2. 1. Unequal Probability Sampling in Active Learning and Traffic Safety

   Author : Henrik Imberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; naturalistic driving; active learning; sampling weighing; optimal design; sequential sampling; probability sampling;

   Abstract : This thesis addresses a problem arising in large and expensive experiments where incomplete data come in abundance but statistical analyses require collection of additional information, which is costly. Out of practical and economical considerations, it is necessary to restrict the analysis to a subset of the original database, which inevitably will cause a loss of valuable information; thus, choosing this subset in a manner that captures as much of the available information as possible is essential.

4. 2. An Experimental Study of a Liquid Steel Sampling Process

   Author : Ola Ericsson; Andrey Karasev; Pär Jönsson; Lauri Holappa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; inclusion characteristics; sampling conditions; sample homogeneity.; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : During the steelmaking process samples are taken from the liquid steel, mainly to assess the chemical composition of the steel. Recently, methods for rapid determination of inclusion characteristics (size and composition) have progressed to the level where they can be implemented in process control. READ MORE

5. 3. Particulate phosphorus accumulation and net retention in constructed wetlands receiving agricultural runoff : Critical analysis of factors affecting retention estimates

   Author : Karin Johannesson; Karin Tonderski; Stefan Weisner; Uno Wennergren; Ben Surridge; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Phosphorus retention; constructed wetlands; agriculture; sampling strategy;

   Abstract : Övergödning är ett allvarligt miljöproblem, som bland annat orsakar omfattande blomningar av alger och blågrönbakterier. I söt- och brackvatten är fosfor ofta det mest begränsande näringsämnet för dessa organismer, varför en minskning av fosfortillförseln är nödvändig för att nå förbättringar. READ MORE

6. 4. Modeling and simulation of intrinsically disordered proteins

   Author : Joao Henriques; Beräkningskemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Intrinsically disordered proteins; Coarse-grained models; Atomistic models; Metropolis Monte Carlo simulations; Molecular dynamics simulations; Sampling; Conformational analysis; Charge regulation; Surface adsorption;

   Abstract : This work is primarily about the development, validation and application of computer simulation models for intrinsically disordered proteins, both in solution and in the presence of uniformly charged, ideal surfaces. The models in question are either coarse-grained or atomistic in nature, and their applications are dependent on the specific purpose of each study. READ MORE

7. 5. Signal readout and sampling in CMOS

   Author : Darius Jakonis; Linköpings universitet; []
   Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : Advances in CMOS technology have resulted in high-performance and low-cost consumer electronics. One of the main driving forces in this progress is technology scaling. The development of integrated circuits is continuously moving to a system-on-chip realization. READ MORE
