WOMEN AND DEVELOPMENT INTRODUCTION 20. 01 Women constitute an important pool of resource that can be mobilized to achieve the national development agenda. Through the continuous efforts of the Government in providing an enabling environment during the Seventh Plan period, women continued to participate in and contribut e towards the social and economic development of the country. 20. 02 During the Eighth Plan period, efforts will continue to be undertaken to enhance the role, position and status of women to ensure their participation as equal partners in national development.Women will be provided with the skills and knowledge to cope with the challenges of globalization and fulfil the needs of the knowledge-based economy. II. PROGRESS, 1996-2000 20. 03 During the Seventh Plan period, women continued to make significant contributions in various fields of national development through greater participation in the economy. This was made possible through the further operationalization of the National Policy for Women and its Plan of Action for the Advancement of Women, which included the implementation of gender-sensitive and awareness training programmes.In addition, the removal of legal and institutional constraints that inhibited the participation of women in the development process further facilit ated the involvement of women. Population, Labour Force and Employment 20. 04 Based on the 2000 Population Census, about 48. 9 per cent or 11. 4 million of the total population were women. The age-structure of the female Chapter 20 557 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan Ma population was similar to that of the male, with 52. 4 per cent of the female population in the age-group 24 years and below.The Census also revealed that due to the improved female life expectancy, the proportion of the female population in the 65 to 74 years age-group increased from 3. 0 per cent in 1991 to 4. 3 per cent in 2000. 20. 05 Although 48 per cent of women were in the working age population of 15-64 years, they only accounted for a third of the labour force. Female labour force participation registered an increase, from 43. 5 per cent in 1995 to 45. 8 per cent in 1997, but declined to 44 per cent in 1998 due to the economic downturn. W ith the economic recovery, this rate subsequently increased to 44. per cent in 2000. 20. 06 Female employment in the mining and quarrying sector experienced the largest decline of 4. 9 per cent, between 1995 and 2000, followed by the agriculture, forestry, livestock and fishing sector, which recorded a decline of 1. 8 per cent during the same period, as shown in Table 20-1. Various efforts were undertaken to assist these women to re-enter the job market, including the implementation of training programmes to encourage them to venture into small businesses as well as retraining, and the identification and placement of these women in alternative jobs. 0. 07 Overall, the manufacturing sector absorbed the largest share of employed women accounting for 27. 3 per cent in 2000, consistent with the expanding opportunities in the sector. Another sector that recorded high female employment is the wholesale and retail trade, hotel and restaurants, as shown in Table 20-2. 20. 08 Improvements we re recorded in the occupational structure, with more women moving into higher-paying occupations during the Plan period. The proportion of women in the professional and technical category increased from 12. 7 per cent in 1995 to 13. per cent in 2000, while the proportion of women in the administrative and managerial category recorded an increase of 0. 4 per cent during the same period, as shown in Table 20-3. The share of women employed as agriculture workers declined from 16. 6 per cent in 1995 to 14. 8 per cent in 2000, consistent with the overall decline in total employment in the sector. Women were mainly employed as production and related workers, which accounted for 22. 6 per cent of total female employment in 2000. 558 TABLE 20-1 EMPLOYMENT DISTRIBUTION BY GENDER WITHIN SECTORS, 1995 AND 2000 (%) 1995 2000Sector Male Female Male Female Agriculture, Forestry, Livestock & Fishing 71. 4 28. 6 73. 2 26. 8 Mining & Quarrying 82. 1 17. 9 87. 0 13. 0 Manufacturing 57. 2 42. 8 58. 9 41. 1 Construction 93. 5 6. 5 94. 0 6. 0 Electricity, Gas & Water 90. 4 9. 6 90. 5 9. 5 Transport, Storage & Communications 87. 9 12. 1 86. 9 13. 1 Wholesale & Retail Trade, Hotel & Restaurants 61. 3 38. 7 60. 7 39. 3 Finance, Insurance, Real Estate & Business Services 60. 1 39. 9 60. 1 39. 9 Other Services 60. 0 40. 0 54. 7 45. 3 66. 1 33. 9 65. 5 34. 5 Total TABLE 20-2 EMPLOYMENT DISTRIBUTION BY SECTOR AND GENDER, 995 AND 2000 (%) 1995 2000 Sector Male Female Male Female 21. 6 16. 9 20. 2 14. 1 0. 5 0. 2 0. 4 0. 1 Manufacturing 20. 2 29. 4 20. 6 27. 3 Construction 11. 3 1. 5 12. 1 1. 5 0. 9 0. 2 0. 7 0. 1 Agriculture, Forestry, Livestock & Fishing Mining & Quarrying Electricity, Gas & Water Transport, Storage & Communications 6. 2 Finance, Insurance, Real Estate & Business Services 1. 7 6. 1 1. 7 16. 6 Wholesale & Retail Trade, Hotel & Restaurants 20. 5 18. 1 22. 3 4. 5 5. 7 17. 2 27. 1 100. 0 100. 0 100. 0 Chapter 20 559 5. 6 24. 0 100. 0 Total 4. 3 18. 4 Other ServicesMalaysia P lan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan Ma TABLE 20-3 EMPLOYMENT DISTRIBUTION BY OCCUPATION AND GENDER, 1995 AND 2000 (%) 1995 2000 Occupation Category Male Female Male Female Professional, Technical & Related Workers 8. 4 12. 7 8. 9 13. 5 Administrative & Managerial Workers 3. 9 1. 8 4. 7 2. 2 Clerical & Related Workers 7. 5 17. 5 7. 1 17. 5 10. 5 11. 6 11. 1 12. 1 9. 4 14. 4 9. 5 17. 4 Agriculture Workers 21. 9 16. 6 20. 4 14. 8 Production & Related Workers 38. 3 25. 4 38. 4 22. 6 100. 0 100. 0 100. 0 100. Sales & Related Workers Service Workers Total 20. 09 Various measures were undertaken to improve female participation in the labour market. The Employment Act 1955 was amended in 1998, which among others, provided for flexible working hours and empowered the Minister of Human Resources to make rules on statutory benefits to be paid to part-time workers proportionate to that of full-time employees. This amendment permitted wome n, especially housewives, to be gainfully employed in part-time employment, while allowing them the flexibility to meet their family obligations.In an effort to allow women in the public sector to care for their newborn and to encourage breastfeeding, as of May 1998, maternity leave up to 60 days was allowed for a maximum of up to five children. In addition, provisions for tax deductions were provided to employers for the establishment of child-care centres near or at the workplace. Employers were also encouraged to provide facilities such as proper housing, transport and healthcare for the benefit of rural migrants, the majority of whom were women. Educational Attainment 20. 0 An important factor that contributed towards the social and economic advancement of women was the huge investments in educational facilities 560 accompanied by the provision of equal access to educational opportunities. Female primary and secondary school enrolment in local public institutions reflected the g ender ratio in the country. At the primary and secondary levels, enrolment of female students was about half of the total enrolment, while at the upper secondary level, female students accounted for about 66 per cent of total enrolment in 2000.Intake of female students into public universities expanded significantly from 50 per cent in 1995 to 55 per cent in 2000. 20. 11 With regard to preference for courses, female dominance in the arts streams continued to be prevalent accounting for 65 per cent of total enrolment in the arts and humanities courses in 2000. Females also made further inroads into science and technical courses. Female enrolment in the sciences in institutions of higher learning accounted for 60 per cent, while in the technical field it was 30 per cent in 2000.Skills and Entrepreneur Development 20. 12 Specific skills and entrepreneur training programmes were implemented to enable women to improve themselves and take advantage of the opportunities in the job market. In this regard, courses in areas such as business, organizational and financial management were implemented. Skills training programmes provided by the Centre for Instructor and Advanced Skills Training were expanded, resulting in an increase of 19. 4 per cent in the female enrolment between 1995 and 2000. 20. 3 With improved literacy and the changing needs of the rural community, courses that contributed towards the involvement of women in income-generating activities were also undertaken. Towards this end, extension services in the form of the provision of equipment, initial capital grants, advisory services and training in areas such as product processing, as well as leadership and motivation courses were conducted. 20. 14 Measures were undertaken to facilitate the involvement of women in business through the provision of easy access to capital. The Women Entrepreneurs Fund was established in 1998 with an allocation of RM10 million.A total of 12 projects amounting to RM9. 5 milli on was approved under the Fund. Through the Small Entrepreneur Fund, a total of about 6,000 women entrepreneurs obtained loans amounting to RM65 million. Chapter 20 561 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan Ma 20. 15 Various women entrepreneur and industry associations were formed, generally to serve as a platform for women entrepreneurs to establish networks and exchange information and experiences as well as to conduct training programmes, seminars, and workshops on motivation, leadership and entrepreneur development.The Women’s Institute of Management (WIM) offered skills training courses, particularly in the area of entrepreneurship as well as operated an on-line network called WIMNET that provided database search facilities to businesswomen around the world. In addition, the Institute of Women’s Advancement, the Federation of Women Entrepreneurs Association and the Association for Bumiputera Women En trepreneurs conducted courses and seminars in skills and entrepreneur development.A total of about 10,000 women benefited from these courses. Research and Development 20. 16 Women were actively involved in research and development activities during the Plan period. According to the 1998 National Survey of Research and Development, which covered research undertaken by government research institutions, institutions of higher learning and the private sector, women accounted for about a third of the total number of researchers with masters and bachelor degree qualifications, as shown in Table 20-4.In terms of research fields in the public sector, females were predominantly found in the medical and health and information sectors.

As such, the health status of women continued to register improvements during the Plan period. The average female life expectancy continued to improve from 74 years in 1995 to 74. 7 years in 2000 compared with 69. 3 years and 69. 9 years, respectively, for males. The maternal mortality rate, which is an indicator of the health status of women, remained low at 0. 2 per 1,000 live births during the Plan period. 20. 8 With the introduction of the Family Health Programme in 1996, women’s health was given emphasis from two perspectives, namely, the health of the family comprising maternal and child health, immunization, family planning, early detection of cancers and nutrition, as well as diseases affecting women with specific attention to human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS). The maternal and child health programme, aimed at reducing maternal and infant mortality and morbidity, improving prenatal and antenatal healthcare and providing health and utrition education continued to be implemented. In addition, increased accessibility to safe delivery services contributed towards the achievement of a satisfactory maternal mortality rate. As a result, deliveries in the public sector health facilities increased from 85. 1 per cent in 1985 to 95. 3 per cent in 1999. Concerted efforts were also undertaken to widen the coverage of antenatal health care services resulting in 72 per cent of pregnant women having access to such services.The Government introduced the Nutrition Rehabilitation Programme for Pregnant Mothers in 1997 to further improve the health status of women through the provision of adequate nutrition, particularly women in t he low-income group. 20. 19 With longer life expectancy and to ensure that women are healthy and remain healthy in their old age, health education programmes, seminars and workshops on healthy lifestyles, nutrition and the importance of regular medical examinations were introduced by the public and private sectors.In view of the fact that women, especially young women, are in the high-risk category in terms of vulnerability to AIDS, greater emphasis was given towards providing information on AIDS awareness and education. Despite these efforts, the percentage of women with HIV infection increased from 4. 3 per cent in 1995 to 5. 1 per cent in 1999. A programme, specifically for pregnant mothers infected with HIV, was also introduced at all antenatal clinics. Chapter 20 563 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan MaPoverty among Female-headed Households 20. 20 Recognizing that increasing poverty among women is a world-wide phenomenon, various efforts were undertaken by the Government and nongovernmental organizations (NGOs) to reduce the incidence of poverty among women. These included the provision of micro-credit facilities to about 22,850 women through Amanah Ikhtiar Malaysia to facilitate their involvement in small businesses and training programmes to assist single mothers to obtain employment. Despite these efforts, the incidence of poverty among female-headed households increased from 15. per cent or 585,688 households in 1997 to 16. 1 per cent or 588,554 households in 1999. Supportive Legislation 20. 21 During the period, efforts to further enhance the status of women continued to be undertaken. Existing regulations were reviewed and new ones enacted to protect the rights and dignity of women in both public and private life. In recognition of the importance of women’s contribution to the labour force, the amendment of the Employment Act 1955 encouraged more women to join the labour for ce.With the increased participation of women in the labour force, the existence of a healthy working environment is crucial. Towards this end, in 1999 the Government introduced a code of ethics for the prevention of sexual harassment at the workplace. This code, although applicable to both men and women, contains specific provisions to protect women in the workplace. In addition, women taxpayers, whose husbands had no taxable income, were provided taxable relief similar to that available to a male taxpayer whose wife had no taxable income. 20. 2 To enhance the capability and capacity of syariah courts, including in the handling of issues pertaining to Muslim women, the Government initiated a review of the organization of syariah courts in the country. Consequently, the Department of Syariah Judiciary was established in 1997, among others, aimed at ensuring uniformity among states in the judgement of cases pertaining to Islamic Family Law. During the period, five states, namely, Mela ka, Negeri Sembilan, Perlis, Pulau Pinang and Selangor as well as the Federal Territory of Kuala Lumpur implemented the Islamic Family Law.With this implementation, Muslim women were provided with better protection. 564 20. 23 Various efforts were undertaken to further protect the rights and dignity of women. The Women and Girls Protection Act 1973 and the Child Protection Act 1991 were reviewed and streamlined into the Child Act 2000. In addition, recognizing the role of women in caring for their families, the Guardianship of Infants Act 1961 was amended in 1999 to allow joint guardianship of children in matters relating to immigration and registration.In implementing this amendment, the Government, in 2000, also allowed mothers to sign all documents involving their underage children. National Machinery for the Advancement of Women 20. 24 The national machinery for the advancement of women in Malaysia comprises the Government, the private sector and NGOs, working in tandem towards the common objective of improving the status of women. Recognizing the need to further enhance the effectiveness of the national machinery, the Women’s Affairs Department at the Ministry of National Unity and Social Development was transferred to the Prime Minister’s Department in 1999.To enable more effective implementation of the National Policy for Women, the Plan of Action for the Advancement of Women was introduced to all public and private sector agencies to be used as a guide in the planning and implementation of development programmes. In addition, gender sensitization training programmes continued to be implemented in the public sector and similar programmes were initiated in the private sector. 20. 5 During the period, the National Advisory Council on the Integration of Women in Development (NACIWID) continued to function as the coordinating, consultative and advisory body on women’s affairs by highlighting to the Government issues and concerns pertain ing to women. Measures were also undertaken to institute links with the grassroot through the establishment of women service centres at the state level and women’s affairs consultative committees at the state and district levels.During the Plan period, centres were established in the States of Kedah, Kelantan, Pahang, Sabah and Selangor, which provided various services such as counselling, legal assistance and temporary shelter for women in need. The consultative committees monitored the implementation and impact of programmes and projects for women and provided the necessary feedback for improved project formulation and implementation. 20. 26 NGOs played an important role in complementing the efforts of the Government in advancing the status of women.In addition to organizing courses in family health, legal literacy, entrepreneurial development and parenting skills, Chapter 20 565 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malays ia Plan Ma NGOs also implemented various activities to increase the knowledge and skills of women in the vocational and technical fields. Specific programmes were also introduced to assist single mothers in obtaining employment and caring for their families. NGOs also played the catalytic role in highlighting issues to further improve the status and rights of women.III. PROSPECTS, 2001-2005 20. 27 During the Eighth Plan period, efforts will continue to be undertaken to further enhance the role, position and responsibilities of women so as to increase their participation and involvement in the social and economic life of the country. In implementing the Plan of Action for the Advancement of Women, the Government will continue to ensure that strategies and programmes implemented are consistent with Malaysian values, religious beliefs and cultural norms. 20. 8 Taking cognizance of the changes in the global environment and the need to adjust to these changes, efforts will be undertaken to provide women with the skills and knowledge to cope with the twin responsibilities of family and career. Towards this end, the strategic thrusts for the future advancement of women will be: t increasing female participation in the labour market; t providing more education and training opportunities for women to meet the demands of the knowledge-based economy and improve their upward mobility in the labour market; t enhancing women’s involvement in business; reviewing laws and regulations that inhibit the advancement of women; t improving further the health status of women; t reducing the incidence of poverty among female-headed households; t strengthening research activities to increase participation of women in development and enhance their well-being; and t strengthening the national machinery and the institutional capacity for the advancement of women. 566 Increasing Female Participation in the Labour Force 20. 29 Although women account for nearly half of the working ag e population, their participation in the labour force is relatively low.Various efforts will be undertaken to mobilize this available pool of resource, thus increasing the supply of labour and contributing towards enhancing the nation’s output. The private sector, being the largest employer, will be further encouraged to introduce the necessary support facilities such as establishing child-care centres as well as providing transportation and housing facilities for their women employees. In addition, the Employment Act 1955 will be amended to include new and flexible working arrangements such as teleworking, part-time work and job sharing, to enable women to integrate career with household duties.Providing More Education and Training Opportunities 20. 30 Women will be provided with more education and training opportunities to meet the demands of the knowledge-based economy as well as to facilitate their upward mobility into higher-paying occupations. To encourage more women to pursue non-traditional fields of study such as science, engineering and vocational and technical education, career counselling programmes will be implemented to provide information and instill greater awareness among female students and parents regarding career opportunities in the professional and technical fields. 0. 31 With the need to increase knowledge and skills as well as move towards higher capital intensity, there will be a greater demand for highly and multiskilled workers. Women will thus be provided with more training opportunities to acquire new and advanced skills relevant to the needs of the industry. In addition, in response to the rapid changes in technology that requires constant upgrading of skills, women will be provided with increased opportunities for retraining.The private sector will also be encouraged to complement the efforts of the Government in providing more skills training opportunities for women, including in new technologies. 20. 32 Efforts will be u ndertaken to improve women’s access to information and communications technology (ICT). Formal and non-formal training in areas such as computer literacy and applications of ICT will be conducted jointly by the Government and NGOs, with special emphasis given to rural women. In addition, to enhance the effectiveness of the training programmes, efforts will be taken to ensure that software development is gender sensitive.Chapter 20 567 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan Ma Enhancing Women’s Involvement in Business 20. 33 Efforts to enhance women’s involvement in business will continue to be undertaken. Training in business-related areas such as marketing, accounting, budgeting and planning will be implemented by the Government and NGOs. Programmes will be implemented to enable women entrepreneurs to be more competitive in terms of production, product quality and design as well as packaging and la belling. In addition, the utilization of ICT in business will be emphasized.The Government will also continue to provide funds under the Women Entrepreneurs Fund to enable more women to participate in business. Through the implementation of gender sensitive strategies, more opportunities will be provided to women to increase their participation and involvement in business ventures. Reviewing Laws and Regulations 20. 34 Existing laws and regulations will be reviewed to eliminate provisions that discriminate or have adverse effects on women. Legislation that will be reviewed includes those pertaining to family law and the distribution of property for non-Muslims.The Government will study the feasibility of establishing family courts with a view towards ensuring that issues pertaining to the family are discussed and decisions made in a more conducive environment. Efforts will also be undertaken to ensure the effective enforcement and speedy implementation of court decisions, including decisions of syariah courts, so as to provide for the protection and welfare of women. In addition, steps will continue to be taken to ensure the implementation of Islamic Family Law in the remaining states. Improving the Health Status 20. 5 Emphasis will continue to be given to promoting women’s health and that of their families. Through the family health programme, special attention will be given to HIV and sexually-transmitted infection prevention, family planning, as well as the identification of factors causing non-communicable diseases such as cancers, mental illnesses and cardiovascular diseases. In view of the fact that women have longer life expectancy and to ensure that women remain healthy in their old age, specific health education programmes including the promotion of healthy lifestyles and nutrition will continue to be implemented. 68 20. 36 Recognizing the peculiarities of illnesses confronting women, such as osteoporosis and those related to reproductive healt h, and in an effort to provide higher quality healthcare for women, the Government will establish a special hospital for women. This hospital will be the national referral centre for women’s health and well-being. In addition, research on various aspects of women’s health will be undertaken, with emphasis on biomedical, socio-behavioural and clinical research. Reducing the Incidence of Poverty among Female-headed Households 20. 7 In view of the increasing number of female-headed households and the rising incidence of poverty among them, efforts will be undertaken to ensure that these women have the capacity and capability to care for their families. Towards this end, research on the difficulties faced by women as head of households as well as the differing impacts of poverty on women and men will be undertaken to assist in the development of relevant programmes and projects. A special programme aimed at reducing the incidence of poverty among female-headed households w ill also be formulated to improve their quality of life as well as that of their families.Strengthening Research Activities 20. 38 During the Plan period, emphasis will be given to strengthening research in specific areas that will contribute towards increasing the participation of women in national development and enhancing their well-being. Research will be undertaken in areas such as the involvement of women in science and technology and ICT, the welfare of women in the informal sector, the role and status of women in the workplace, mobility of women in the labour force and remunerations received, women and mental health, and difficulties faced by women as head of households.Findings from these activities will assist in the formulation of policies and programmes that will further promote the advancement of women. Strengthening the National Machinery and the Institutional Capacity 20. 39 The establishment of the Ministry for Women and Family Development will provide greater focus on issues relating to women as well as ensure the effective implementation and coordination of programmes for women and families. Chapter 20 569 Malaysia Plan Ma laysia Plan Malay 8 sia Plan Malaysia Plan Malaysia Pl an Malaysia Plan Malaysia Plan MaConsistent with the goals of the National Policy for Women, efforts will be undertaken to improve and strengthen the national machinery for the advancement of women. Towards this end, measures will be instituted to ensure greater coordination and collaboration in the implementation of activities for women. In addition, links with the grassroots will continue to be strengthened with the establishment of women service centres in the remaining 10 states. 20. 40 During the Plan period, various mechanisms will be instituted to enable women to participate in decision-making processes at all levels.This is to ensure the incorporation of the needs of women in the formulation of policies and the development of strategies and programmes for the fu rther advancement of women. Gender analysis training and sensitization for policy-makers and planners and programme implementors will continue to be implemented in the public and private sectors. Greater efforts will also be undertaken to ensure the systematic collection and compilation of gender disaggregated data to facilitate analysis, create awareness and formulate appropriate and effective follow-up action on gender issues. IV. CONCLUSION 0. 41 With the provision of equal access to healthcare as well as educational and training programmes and improved employment opportunities, women made advancements in various fields of development. During the Eighth Plan period, efforts will continue to further enhance the status of women as equal partners in development. Towards this end, the Government will provide the enabling environment and supportive mechanisms, including the implementation of gender sensitive programmes, to enable women to reach their full potential in the social and e conomic fields of development. 570

Tolerance Analysis

A Comprehensive System for Computer-Aided Tolerance Analysis of 2-D†¦ http://adcats. et. byu. edu/Publication/97-4/cirp_2_7_97a. html 7. 0 ASSEMBLY TOLERANCE SPECIFICATIONS An engineering design must perform properly in spite of dimensional variation. To achieve this, engineering design requirements must be expressed as assembly tolerance limits. The designer must assign limits to the gaps, clearances and overall dimensions of an assembly which are critical to performance.Assembly tolerance limits are applied to the statistical distribution of the assembly variations predicted by tolerance analysis to estimate the number of assemblies which will be within the specifications. Designers need to control more than just gaps and clearances in assemblies. Orientation and position of features may also be important to performance. To be a comprehensive design tool, a tolerance analysis system must provide a set of assembly tolerance specifications which covers a wide range of common des ign requirements. A system of assembly tolerance specifications patterned after ANSI Y14. 5 has been proposed [Carr 93].Those ANSI Y14. 5 feature controls which require a datum appear to be useful as assembly controls. However, there is a distinct difference between component tolerance and assembly tolerance specifications, as seen in Fig. 9. In the component tolerance specification shown, the parallelism tolerance zone is defined as parallel to datum A, a reference surface on the same part. By contrast, the assembly parallelism tolerance defines a tolerance zone on one part in the assembly which is parallel to a datum on another part. In order to distinguish an assembly tolerance specification from a component specification, new symbols have been proposed.The feature control block and the assembly datum have been enclosed in double boxes. Fig. 9 Comparison of component and assembly tolerance specifications. 8. 0 MODELING PROCEDURES AND RULES The ability to model a system is a funda mental skill for effective engineering design or manufacturing systems analysis. Unfortunately, few engineers know how to construct variational models of assemblies beyond a 1-D stack. This is primarily because the methods have not been established. There is little treatment of assembly modeling for tolerance analysis in engineering schools or texts.Until engineers learn how to model, tolerance analysis will never become widely used as have other CAD/CAE tools. A consistent set of modeling procedures, with some guiding rules for creating vector assembly models, allows for a systematic approach which can be applied to virtually any assembly. The steps in creating a model are: 1. Identify the assembly features critical to the assembly. Locate and orient each feature and specify the assembly tolerances. 2. Locate a datum reference frame (DRF) for each part. All model features will be located relative to the DRFs. 3.Place kinematic joints at the points of contact between each pair of ma ting parts. Define the joint type and orient the joint axes. These are the assembly constraints. 4. Create vector paths from the DRF on each part to each joint on the part. The paths, called datum paths, must follow feature dimensions until arriving at the joint. Thus, each joint may be located relative to the DRF by controlled engineering dimensions. 5. Define the closed vector loops which hold the assembly together. The datum paths defined in Step 2 7 of 14 5/11/2011 4:27 PM A Comprehensive System for Computer-Aided Tolerance Analysis of 2-D†¦ ttp://adcats. et. byu. edu/Publication/97-4/cirp_2_7_97a. html become segments of the vector loop. A vector loop must enter a part through a joint and leave through another joint, passing through the DRF along the way. Thus, the vector path across a part follows the datum path from the incoming joint to the DRF and follows another datum path from the DRF to the outgoing joint. 6. Define open vector loops to describe each assembly tolera nce specification. For example, for an assembly gap, the loop would start on one side of the gap, pass through the assembly, and end at the other side of the gap. 7.Add geometric variations at each joint. Define the width of the tolerance zone and length of contact between the mating parts as required. The nature of the variation and direction is determined by the joint type and joint axes. Other variations, such as position, may be added at other feature locations. Modeling rules are needed to ensure the creation of valid loops, a sufficient number of loops, correct datum paths, etc. For example, an important set of rules defines the path a vector loop must take to cross a joint. Each joint introduces kinematic variables into the assembly which must be included in the vector model.Fig. 10 shows the vector path across a 2-D cylinder-slider joint. The rule states that the loop must enter and exit the joint through the local joint datums, in this case, the center of the cylinder and a reference datum on the sliding plane. This assures that the two kinematic variables introduced by this joint are included in the loop, namely, the vector U in the sliding plane and the relative angle f at the center of the cylinder, both of which locate the variable point of contact in their corresponding mating parts. Fig. 11 shows a similar vector path through a 3-D crossed cylinders joint.A more complete set of modeling rules is described in [Chase 94]. Fig. 10: 2-D vector path through a joint Fig. 11 3-D vector path through a joint 9. 0 MODELING EXAMPLE The process of creating an assembly tolerance model for analysis is illustrated in the figures below for a seatbelt retraction mechanism. The device is an inertial locking mechanism for the take-up reel. One of the critical assembly features is the gap between the tip of the locking pawl and the gear, as shown in Fig. 12. The assembly is of reasonable complexity, with about 20 dimensional variations and several geometric variati ons as contributing sources.The contribution by each variation source depends on the sensitivity of the gap to each component variation. Fig. 13 shows the DRFs for each part and local feature datums which define model dimensions. 8 of 14 5/11/2011 4:27 PM A Comprehensive System for Computer-Aided Tolerance Analysis of 2-D†¦ http://adcats. et. byu. edu/Publication/97-4/cirp_2_7_97a. html Fig. 12 Example 2-D assembly Fig. 13 Part DRFs and feature datums. In Figure 14, the kinematic joints defining the mating conditions are located and oriented. Clearance in the rotating joints was modeled by two methods.In the first case, the shafts were modeled as revolute joints, centered in the clearance, with clearance variation added as an equivalent concentricity. In the second case, the CAD model was modified so each shaft was in contact with the edge of the hole, modeled by parallel cylinder joints, and variation was determined about this extreme position. After the joints have been locat ed, the assembly loops can then be generated, as shown in Fig. 15. To simplify the figure, some of the vectors are not shown. Fig. 14 Kinematic joints define mating conditions. Fig. 5 Vector loops describe assembly. Models for geometric variation may then be inserted into the vector assembly model, as shown in Fig. 16. The completed CATS model, in Fig. 17, is ready for assembly tolerance analysis. 9 of 14 5/11/2011 4:27 PM A Comprehensive System for Computer-Aided Tolerance Analysis of 2-D†¦ http://adcats. et. byu. edu/Publication/97-4/cirp_2_7_97a. html Fig. 16 Geometric variation sources are added.

Fig. 18 3-D CATS model. 10. 0 TOLERANCE ANALYSISThe analysis approach used within the CATS system is based on linearization of the assembly equations and solution for the variations by matrix algebra. A detailed description with examples may be found in [Chase 95, 96] and [Gao 97]. The linearized method provides an accurate and real-time analysis capability that is compatible with engineering design approaches and tools. Vector assembly models can be used with any analysis system. Gao used the CATS Modeler as a graphical front end for 10 of 14 5/11/2011 4:27 PM A Comprehensive System for Computer-Aided Tolerance Analysis of 2-D†¦ http://adcats. et. byu. du/Publication/97-4/cirp_2_7_97a. html a Monte Carlo simulator [Gao 93]. An iterative solution was used to close the vector loops for each simulated assembly. Histograms for each assembly feature being analyzed were generated from the computed assembly dimensions. A comparison of the linearized approach with Monte Carlo analysis is presented in [Gao 95]. 11. 0 CAD IMPLEMENTATION Fig. 19 shows the structure of the Computer-Aided Tolerancing System integrated with a commercial 3-D CAD system. The CATS ® Modeler creates an engineering model of an assembly as a graphical and symbolic overla y, linked associatively to the CAD model.Pop-up menus present lists of joints, datums, g-tols and design specs to add to the CAD model. The model is created completely within the graphical interface of the CAD system. There are no equations to type in to define mating conditions or other assembly relationships. CATS is tightly integrated with each CAD system, so it becomes an extension of the designer's own CAD system. Current CAD implementations include: Pro/ENGINEERa (TI/TOL 3D+), CATIAa, CADDS5a, and AutoCADa; (AutoCATS). Fig. 19 The CATS System Architecture The CATS Analyzer accesses the assembly tolerance model that was created and stored in the CAD system.The Analyzer has built-in statistical algorithms to predict variation in critical assembly features due to process variation. It features built-in algorithms for tolerance synthesis, which re-size selected tolerances to meet target assembly quality levels. Matrix analysis gives instant feedback for any design iteration or â⠂¬Å"what-if† study. The user interface is standard XWindows Motif, with multiple windows, scroll bars, pop-up menus, dialog boxes, option buttons, data fields and slide bars for data entry, etc. The designer is in complete control of the tolerance analysis/design process.Graphical plots give visual feedback in the form of statistical distributions, ranked sensitivity and percent contribution plots. Engineering limits are shown on the distribution, with corresponding parts-per-million reject values displayed. The current status of the CATS Modeler and Analyzer, with respect to ease of use by an interactive graphical user interface and internal automation are summarized in Table 1 and Table 2. Table 1.

Tactics Paper Essay Example | Topics and Well Written Essays - 2000 words

Tactics Paper - Essay Example How could a group of colonies spread out over a vast region with no central government or treasury and an army that was inadequately trained and equipped possibly defeat the British who were the most powerful military force at that time? Britain had ruled over the thirteen colonies in America for more than 200 years prior to the Revolution. By the beginning of the Revolution, the wars against France fought on both sides of the Atlantic had burdened Britain with a massive national debt. To ease the national debt, Parliament imposed taxes on the colonists believing it only fair that they bear part of the expenses incurred by the British military in protecting them from Indian attacks and French invasions. The Stamp Act taxed paper goods sent to the colonies. It was the first of these laws while, with the tea tax, was one of the most infamous of these laws. The colonists thought taxation without representation in the British government to be unjust and openly protested these laws which led to hostilities between British troops and the Massachusetts Minutemen in 1775. This and other conflicts with the ‘Red Coats’ led to colonists forming the Continental Congress which immediately created the Continental Arm y and in 1776, signed the Declaration of Independence. The Americans, outmatched by more than three-to-one, were predictably defeated in the majority of battles that occurred during the war’s first year. However, the Americans’ fortune began to change following the victories at Saratoga and Germantown in 1777. These important first triumphs gave increased credibility to what had previously been widely considered as an unorganized, minor uprising certain to be vanquished by the mighty British army. By 1778, France had become convinced that Britain stood the chance of being defeated. Wanting nothing more than this, America’s first formal alliance was

Dance review Movie Example | Topics and Well Written Essays - 750 words

Dance - Movie Review Example The performance is structured around a collection of themes as well as reoccurring settings. The work can be viewed as being light but punctuated with some heavier moments. The choreographer, Barton ventures more into subjects regarding femininity, masculinity, ritual, water and nurture. The choreography depicted from the performance is quite demanding but despite this the performers rise to the challenge. There are three dancers that standout due to the fact that they are heavily featured: Davon Rainey, William Briscoe and Jonathan Alsberry. The three dancers are quite captivating based on their fast as well as a percussive unison section where they are able to sway their hips and also strut their things in a quite incredible but yet masculine way. The piece Awaa is a one evening length that is performed within a condensed time frame of about 45 minutes from the full version which was 75 minutes(Barton). The dance is a group work performed by six male and one female. The movements are simple and effectively magnified in order to suit the rhythm of the music selected. The dance movements are fast and greatly coordinated among the dancers. The dancers move at a meditative pace as they execute each routine of their performance. Based on my perception I tend to think that the choreographer, Barton tends to leave most of the explanation of the performance to the audience. Nevertheless, the performance made me view different aspects that are involved in choreography. The work clearly shows the relationship that tends to exist between dance and music. The dance routine must be greatly coordinated with the music that goes along with it. The piece Awaa has a unique dance routine that tries to tell a story based on the subjects of femininity and masculinity but due to the element of confusing array of the projected images it is quite difficult to formulate the entire story or what message the dance is trying to pass across to the audience. The dancers

Economics and Business of the Asia Pacific Region Essay

Economics and Business of the Asia Pacific Region - Essay Example The country focused on enhancing its economic situation by introducing positive alterations in its income, output along with employment. The reform also aimed at altering the economic structure of China fostering foreign trade to a large extent from. It can be stated that the post-Mao reforms in China were more focused on the reorganizing the economic structure which tends to restrict sustainable development. Thus, the purposes and objectives relevant to the restructuring can be observed as strongly associated with the economic expansion and progress during the late 1970s (Liou, 1998). On the other hand, the strategy of open door was intended to lure the foreign investors, highly developed technology along with management expertise to the cities of China as well as the coastal regions. This restructuring policy implemented in the post-Mao reform had a significant influence and contribution towards the overall economic growth of China, its economic composition and the distribution of the economic actions in the national stage as well as in the local stage. It is worth mentioning that the contribution of this policy was more apparent in a few specific local regions that that in the overall national environment (Weng, 1998). These development policies contributed greatly towards the enhancement of the macroeconomic functions and the living standards of the residents in China. For instance during 1978 to 1995, the Chinese economy was observed to attain rapid growth which was recorded in majority of the facets of the different economic indicators such as, gross national product by 9.8 percent, boost in per capita GNP by 8.3 percent, boost in the total production value in terms of agriculture by 6.6 percent and boost in the industries total production value by 15.0 percent. This entailed an annual boost of the overall economic performance and thus played a key role in enhancing the living standards as well as macroeconomic functions within the country (Mauri, 2008; L iou, 2000). In addition, the post-Mao economic restructures not only had a positive effect on the Chinese economy but also had a direct as well as an indirect consequence on the other facets that formed the part of the Chinese society including the state-society relations.  

Governance Regulations and Ethics in the UK Essay

Governance Regulations and Ethics in the UK - Essay Example Governance Regulations and Ethics Task 1: Economic Recession 1.0 Introduction In the book, in chapter one, there is a lot of emphasis on corporate responsibility towards ethical issues in management so as to conform to international set standards where the guidelines and management principles that conform across countries and cultures. In the film, it is clear that most countries especially America made attempts to set into place control mechanisms through various acts so as to ensure honest and moral conduct in business. The book brings into focus the dishonest by the investment companies when they undertook to promote internet stock companies they were quite aware would fail. This was in an attempt to precipitate the crisis by, in fact, defrauding innocent investors. This resulted in derivatives. This is an outright case of dishonest as business terms require such loyalty and obligation in the management of the corporations by people charged with the responsibility whether CEOs or employees. 2.0 Issues in the Movie Covered in the Existing Corporate Codes 2.1 The UK Corporate Governance Code of the year 2010 The UK Cooperate Governance Code of the year 2010 is mainly included with the aim of establishing a well a created board of governors for accompany or corporation through principles and rules, as opposed to rigid rules. The main Aim of the code is to ensure proper directorship of companies through the underlying principles of accountability, transparency, probity, and insight into sustainable success. It is clear that the financial crisis as reported in the movie, â€Å"The Inside Job’ was as a result of management of the business with the aim of success but without consideration of the eventual effect of such practices, which were fraudulent, in nature. This is in the book which defines better and acceptable ethical practices in the corporate world 2.2 Flaws in the Implementation of the Code Although the code in section 4 about governance sets out the moral practices of an organization through sound and upright board behavior, implementation, and adherence are not a guarantee. This is evident in the movie since the CEOs of the investment companies did not actually follow the guidelines, though they existed. The Lehman Brothers, for instance, ignored the moral and ethical guidelines and continued promoting borrowing to firms without the capability to remain in the market with that clearly in their knowledge. The firm had to crumble and come down in 2008. 2.3 Role of corporate Leadership in Disregarding the Code Leadership of the chairman of a board, the support is given to and by the chief executive officer and the openness and frankness to discussions by the directors is the key in this endeavor according to the governance code.
