   Author : Karin Björkegren; Kurt Svärdsudd; Åke Schwan; Herman Nilsson-Ehle; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Cobalamin; folate; MMA; tHcy; multivitamin; symptoms; survey; treatment trial; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Family Medicine; Allmänmedicin;

   Abstract : The aims of this study were to document the levels of cobalamin, folate, methylmalonic acid (MMA) and total homocysteine (tHcy) in serum and their relations to symptoms, clinical findings, and other factors in order to improve the possibilities of detecting early deficiency of vitamin B12 or folate, and to study the effects of cobalamin and folic acid treatment over a three-year period. The study population consisted of a 20% random sample of persons 70 years or older living in Älvkarleby in mid-Sweden. READ MORE

5. 3. The Quantification of Society. A Study of a Swedish Research Institute and Survey-Based Social Science

   Author : Christopher Kullenberg; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; quantification; survey; social sciences; SOM Institute; epistemic practice; center of calculation; Actor-Network theory; welfare state;

   Abstract : This thesis is concerned with the contemporary history of quantitative surveys in Sweden. The core epistemic practice of constructing surveys is examined empirically through a case study of the SOM Institute (Samhälle, Opinion, Medier) at University of Gothenburg.

6. 4. Planning for emergence: Confronting rule-based and design-based urban development

   Author : Hye Kyung Lim; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; density; compact city; rule-based approach; diversity; design-based approach; urban resilience; planning by coding; emergent urban form;

   Abstract : Increasing urban populations, climate changes, financial instability, global conflicts, depletion of resources, and increasing land consumption all contribute to the complex and unpredictable urban challenges we are facing today. A compact urban form is promoted by global and local policies, and research has shown the benefits of dense and diverse properties for their capacity to provide complex responses to complex challenges.

7. 5. Event Based Sampling with Application to Spectral Estimation

   Author : Niclas Persson; Fredrik Gustafsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Event based sampling; Time based sampling; Tire pressure monitoring system;

   Abstract : In this thesis event based sampling, estimation of a single resonance frequency and the application indirect tire pressure monitoring system are studied.Event based sampling is an alternative to traditional uniform or equidistant sampling. In event based sampled systems, signals are sampled only when certain pre-defined events take place. READ MORE
