A head-model reconstruction based upon photogrammetric data from Sri Lankan adult males relevant to the design of headgear

Tidskriftsartikel (refereegranskat)abstract
- Due to the large variability in heads and faces in one population, the standard anthropometric dimensions of the head, measured from anatomical landmarks alone, may not suffice for the design of fitting headgear, e.g., helmets. To provide adequate data of the shapes and contours of the head to the designer, appropriate head models sculptured using comprehensive head dimensions, must be developed. This paper describes (a) a procedure of collecting comprehensive anthropometric data of the head using a photogrammetric method and (b) a simple sculpturing technique to reconstruct a head model of the user population

Body size variability between people in developed and developing countries and its impact on the use of imported goods
- 1989
-
Ingår i: International Journal of Industrial Ergonomics. - : Elsevier BV. - 0169-8141 .- 1872-8219. ; 4:2, s. 139-149

Tidskriftsartikel (refereegranskat)abstract
- The Industrially Developing Countries (IDC) today, to a great extent, depend on Industrialized Countries (IC) for the supply of most industrial goods. An attempt has been made to ascertain the degree of design incompatibility experienced by users of these imported goods due to differences in the body sizes of people in producer and user countries. A comparative study of variations in body sizes is made from data available in literature and from anthropometric surveys. The results reveal differences in almost every part of the human body. The need for reliable anthropometric data in respect of IDC is stressed. Urgent measures are required to introduce changes in equipment, particularly for the benefit of users in IDC.

Adult learning, work and citizenship : and reflections from the New Sweden '88 Adult Education Seminars in the USA and Canada, October-November 1988
- 1989
-
Rapport (populärvet., debatt m.m.)abstract
- This document reports the activities and impressions of 30 Swedish adult educators who exchanged ideas, experiences, and research results concerning adult education and learning at more than 20 conferences and seminars organized in the United States and Canada. The foreword briefly summarizes some impressions. (Among them are that adult education is more market-oriented in the United States than in Sweden, which has a more policy-oriented system; that Sweden may have more adults being educated per capita, whereas the United States and Canada may offer a wider variety of programs; and that Sweden may be more concerned with equality as it relates to adult education, whereas personal fulfillment may be a more common value in North America.) Part 1 of the document compares and contrasts the North American and Swedish systems, including such topics as study circles, study finance, outreach activities, workplace learning, public broadcasting, and adult learning, the status of research and development in adult education and the infrastructure of adult learning. Ten references are provided for Part 1. Part 2 contains a set of black and white photographs of the Swedish educators and of people and places they encountered during their visits to North America and Canada. Part 3 provides a smorgasbord of ideas, programs, notes, and references about the trip and the ideas exchanged there

"Fifty-fifty?" : comparative comments on access to adult and higher education in Sweden : paper at an international conference on access to higher education held on March 20-21, 1989 at the South Bank Polytechnic, London, U.K.
- 1989
-
Rapport (populärvet., debatt m.m.)abstract
- It is necessary to develop some comparative indicators in order to describe and compare the systems of education in countries other than one's own. Access to higher education is an important indicator. Currently, 50 percent of the Swedish adult population takes part in some organized learning activity every year and 50 percent of the student population in higher education is composed of adults 25 years old or older. Two principal channels through which adults prepare for higher education are the residential college for adults called the Swedish Folk High School and, most important, the system of municipal adult education called Kumvux. About 13 percent of the Kumvux students begin studies at levels of higher education. The National Board of Education provides an orientation course for adult students and a national education admission test, which gives potential adult students a chance to take university courses. Compulsory school ends at age 16, but more than 90 percent of students continue to the upper secondary level and two-thirds of them take vocational programs for 2 years. A few programs aim at increasing access to higher education for "earmarked" groups of adult students, such as trade union members, women, technicians, and disabled students. Sweden faces a strategic decision about whether to renew the system of higher education as it is or concentrate on developing recruitment strategies for neglected or underrepresented learners.

Thermal expansion of solid parahydrogen at helium temperatures
- 1989
-
Ingår i: Soviet Journal of Low Temperature Physics. - 0360-0335. ; 15:8, s. 492-493
-
Tidskriftsartikel (refereegranskat)abstract
- Thermal expansion of solid parahydrogen is investigated in the temperature range from 0.9 to 5 K. The content of the orthomodification in parahydrogen is 0.13 at. %, and that of nonhydrogen impurities is less than 2 10 - 3 at. %. No anisotropy in thermal expansion was observed within the experimental error. The temperature dependence of the linear expansion coefficient can be described by the expression α=1.82 10 - 7 T3. The obtained values of α are in good agreement with the available data on compressibility and ([partial derivate]p/[partial derivate]T)V. The Grüneisen coefficient is γ=3αV/CV`T=2.00 ± 0.25.
