Modelica - A Language for Physical System Modeling, Visualization and Interaction
No full textModelica is an object-oriented language for modeling of large, complex and heterogeneous physical systems. It is suited for multi-domain modeling, for example for modeling of mechatronics including cars, aircrafts and industrial robots which typically consist of mechanical, electrical and hydraulic subsystems as well as control systems. General equations are used for modeling of the physical phenomena, No particular variable needs to be solved for manually. A Modelica tool will have enough information to do that automatically. The language has been designed to allow tools to generate efficient code automatically. The modeling effort is thus reduced considerably since model components can be reused and tedious and error-prone manual manipulations are not needed. The principles of object-oriented modeling and the details of the Modelica language as well as several examples are presented

f. 7.10.1873 i Bremerhaven
d. 26.11.1914 i Helsingfors
Naturvetaren och kemiläraren Gustaf (Guss) Mattsson var lite efter sekelskiftet 1900 även produktiv som tidningsman, kåsör, författare och politiker. Det är särskilt i dessa roller han blivit känd för eftervärlden. Som skarp och bildad men samtidigt ledig skribent fick han många läsare, också efter sin död i tuberkulos 1914. Särskilt kända i produktionen är de 916 kåserier han skrev för Helsingfors-Posten och Dagens Tidning under rubriken ”I dag”. I de skarpsynta och insiktsfulla kåserierna gjorde han sig också känd som urban helsingforsskildrare. Texterna är centrala som exempel på sin tids finlandssvenska prosa, med inslag av det lokala vardagsspråket i Helsingforsmiljön. I Matssons produktion ingår därtill bland annat politiska översikter och nyskapande reseskildringar, som exempelvis den postumt utgivna En herre for till Zanzibar (1914).

---Gustaf (Guss) Mattsson
s. 7.10.1873 Bremerhavenissa
k. 26.11.1914 Helsingissä
Luonnontieteilijä ja kemianopettaja Gustaf (Guss) Mattsson oli 1900-luvun alussa tuottelias lehtimies, pakinoitsija, kirjailija ja poliitikko. Juuri nämä tehtävät tekivät Mattsonista tunnetun jälkipolville. Mattssonin kirjoitustyyli oli sekä terävä että sivistynyt, mutta samalla myös vapaa. Tämä tyyli soi hänelle laajan lukijakunnan vielä pitkään sen jälkeen, kun hän kuoli tuberkuloosiin vuonna 1914. Erityisen tunnettuja tuotoksia ovat 916 pakinaa, jotka hän kirjoitti Helsingfors-Posten ja Dagens Tidning -lehdille otsikolla “I dag”. Tarkkasilmäiset ja tiedostavat pakinat tekivät hänet myös tunnetuksi urbaanina Helsingin kuvaajana. Tekstit ovat keskeinen esimerkki ajan suomenruotsalaisesta proosasta, ja niissä on myös piirteitä paikallisesta Helsingin ympäristön arkikielestä. Mattssonin tuotoksiin kuuluu tämän lisäksi muun muassa poliittisia katsauksia sekä luovia matkakertomuksia, kuten esimerkiksi postuumisti julkaistussa En herre for till Zanzibar (1914, suom. Suomen mies meni Zanzibariin, 1915).

Teaching Gerontology in Transcultural Academics : A Phenomenographic Study of Thai and Swedish Nurse Educators' Conceptions of Gerontological Nursing
No full textINTRODUCTION: There is an urgent need for registered nurses with gerontological competence within long-term care (LTC) of older adults. Despite increases of life expectancy, LTC for older adults is not emphasized in nursing curricula in neither Sweden nor Thailand. Thus, the aim was to explore conceptions on gerontological nursing (GN) among Swedish and Thai nurse educators. METHOD: A qualitative phenomenographic method, based on open-ended interviews with five Thai and nine Swedish nurse educators was conducted. RESULTS: The results indicate a paradox between the educators' knowledge about the implications of global aging, their hope of own aging, and LTC. The ethical responsibility of being credible and a source of inspiration in teaching about aging are focused, while GN seem to be less important. DISCUSSION: To increase students' interest in GN, measures need to be taken within the educational arenas, where the educators' own conceptions toward GN, cultural aspects of aging, and LTC are discussed.CC BY 4.0Article first published online: January 8, 2022Corresponding Author: Karin Mattsson, Department of Neurobiology, Care Sciences and Society, Karolinska Institutet, Alfred Nobels Allé 23, C2, S-141 52 Huddinge, 171 77 Stockholm, Sweden.

Transport and location effects of a ring road with or without road pricing
No full textMany city authorities consider how to develop long-tem strategies to achieve sustainable transport and land use systems. One of the key issues is the balance between policy measures to increase transport supply and measures to reduce transport demand or to reduce its adverse environmental impact. Some cities grow rapidly. They are often facing increasing congestion problems in their road transport systems. This leads to demand from the citizens or trade and industry for increased road capacity to improve accessibility and to facilitate mobility of people and goods. Such investments alone would not solve the problems, some analysts argue, but would rather induce new car traffic that would keep the congestion more or less at the same level as before. The solution is rather, they claim, to introduce economic instruments such as congestion pricing. Cities are very complex systems. Investments in the road network, or the introduction of congestion pricing, will not only affect the demand for different modes of transport but will also, in the long run, change the location of activities and hence the land use structure of the city. To be able to evaluate such policies appropriately, city and traffic planners need tools that could help them to clarify transport as well as land use effects of different actions. In a long-run perspective they need to be able to analyse the interaction between the transport and land use markets. Will the effects of a policy instrument in the transport market be counteracted or amplified by the relocation of households and workplaces in the land use market? Eliasson and Mattsson (2001) developed a stylised model of a "generic" symmetric city for the simulation of this kind of policies. In the model there are four groups of actors: households, employers, shops and service establish-ments. The households commute to the workplaces and make shopping and service trips by car, public transport or slow mode. In addition, there are road-based goods transport from the workplaces to the shops and service establishments. The different actors locate in the city in response to accessibility factors that are specific to each group of actor. Eliasson and Mattsson (2001) used the model to evaluate transport and land use effects of congestion pricing or a toll ring in the road network. In the present study we extend this analysis to the effects of the introduction of a ring road connecting the innermost suburbs, combined with or without optimal (i.e., marginal cost-based) congestion pricing or a toll ring. The analysis includes the effects on travel time and travel distance by purpose and mode of transport and the effects on the location of households, workplaces, shops and service establishments. A ring road, which is not combined with any economic instrument, will attract activities to the innermost suburbs. Travel by car will increase both in time and distance, while public transport will loose market shares. If the ring road is combined with optimal congestion pricing, this will not change the location pattern very much. The transport effects will be considerable, however. Car traffic volumes will be reduced, and hence congestion and then also car travel times. Part of the car demand will be transferred to public transport and to slow mode that both will increase their shares. If the ring road instead is combined with a toll ring, the location effect depends in an expected way on whether the toll ring is located inside or outside of the ring road. In general, a toll ring has lower car travel reducing effect, and leads to less toll revenues, than an optimal congestion pricing policy. References Eliasson, J. and Mattsson, L.-G.

A Relationship Between Operator Performance and Arousal in Assembly
No full textIn order to meet the challenges of future complex systems, manufacturing companies need to better understand how social sustainability affects the operator. One way of studying this is to investigate the possible relationships between operator performance and emotion in an assembly experiment. 60 participants took part in an experiment to investigate the relationships between operator performance and objective and subjective arousal. Results showed a weak relationship between operator performance and objective arousal but no significant relationship was found between performance and subjective arousal. The relationships indicate that further studies on operator emotion could be important to better assembly performance. A tool for doing this might be the Qsensor used in this experiment (measure of objective arousal). More studies are needed to further investigate found relationship and if objective emotion measures can be used to predict performance at assembly workstations.CC BY-NC-ND 4.0Edited by Rikard SöderbergThe research has been carried out within the framework of the Sustainable Production Initiative and the Production Area of Advance at Chalmers University of Technology.
