2. 1. Improved computerized perimetric threshold strategies

   Author : Boel Bengtsson; Oftalmologi (Malmö); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; probability maps; normal limits; test time; clinical testing; test strategies. glaucoma; test algorithms; false positive answers; Visual field testing; computerized perimetry; Ophtalmology; Oftalmologi;

   Abstract : Perimetric threshold examination is the most important method for diagnosing and monitoring patients with glaucoma. Such examination, however, is time-consuming and often difficult for the elderly patients in whom glaucoma is prevalent. Shorter test strategies have been proposed, but unfortunately also with lower test quality. READ MORE

4. 2. Priority setting strategies for regulatory testing of industrial chemicals

   Author : Anna Nordberg; Christina Rudén; Sven Ove Hansson; Nils Gunnar Lindquist; KTH; []
   Keywords : HUMANIORA; HUMANITIES; risk assessment; risk management; regulatory toxicology; test strategies; prioritisation; REACH; industrial chemicals; History of technology and industry; Teknik- och industrihistoria;

   Abstract : For the majority of the estimated 70,000 industrial chemical substances available on the European market today there is not enough information to enable a reasonably complete assessment of the risks that they might pose to man and the environment. Any strategy for the generation of additional data for these substances should aim at making testing as efficient as possible taking into account environmental and health protection, time, monetary cost and animal welfare.

5. 3. Structuring Exploratory Testing through Test Charter Design and Decision Support

   Author : Ahmad Nauman Ghazi; Kai Petersen; Jürgen Börstler; Burak Turhan; Blekinge Tekniska Högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Exploratory Testing; Software Testing; Test Charter Design; Decision Support; Survey Research; Software Engineering; Session based test management; SBTM; ET;

   Abstract : Context: Exploratory testing (ET) is an approach to test software with a strong focus on personal skills and freedom of the tester. ET emphasises the simultaneous design and execution of tests with minimal test documentation. READ MORE

6. 4. New Constructions for Competitive and Minimal-Adaptive Group Testing

   Author : Muhammad Azam Sheikh; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; strict group testing; disjoint pools; randomization; competitive group testing; minimal-adaptive group testing; exact bounds; competitive ratio;

   Abstract : Group testing (GT) was originally proposed during the World War II in an attempt to minimize the \emph{cost} and \emph{waiting time} in performing identical blood tests of the soldiers for a low-prevalence disease. Formally, the GT problem asks to find $d\ll n$ \emph{defective} elements out of $n$ elements by querying subsets (pools) for the presence of defectives. READ MORE

7. 5. Engineering Competitive and Query-Optimal Minimal-Adaptive Randomized Group Testing Strategies

   Author : Muhammad Azam Sheikh; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; learning by queries; combinatorial search; competitive ratio; randomization; pooling design; group testing; linear program;

   Abstract : Suppose that given is a collection of $n$ elements where $d$ of them are \emph{defective}. We can query an arbitrarily chosen subset of elements which returns Yes if the subset contains at least one defective and No if the subset is free of defectives. The problem of group testing is to identify the defectives with a minimum number of such queries. READ MORE
