This paper deals with the use of ‘hot’ real-world cases for both testing and teaching purposes such as in the Introductory System Dynamics course at Delft University of Technology in the Netherlands. The paper starts with a brief overview of the System Dynamics curriculum. Then the problem-oriented teaching and testing approach is explained, followed by a presentation and discussion of several ...

We propose content-based methods for construction of recommendations for reports in the OLAP reporting tool. Recommendations are generated based on preference information in user profile, which is updated implicitly by collecting and analyzing user activity in the reporting tool. Taking advantage of data about user preferences for data warehouse schema elements, existing reports that potentiall...

Cross-domain algorithms have been introduced to help improving recommendations and to alleviate cold-start problem, especially in small and sparse datasets. These algorithms work by transferring information from source domain(s) to target domain. In this paper, we study if such algorithms can be helpful for large-scale datasets. We introduce a large-scale cross-domain recommender algorithm deri...

The objective of this study was to standardize an HIV Proviral DNA PCR from newly infected HIV-1 individuals. Thirty five consenting, HIV-1 seropositive adults were enrolled in this study. Proviral DNA was extracted by QIAmp® DNA Mini Kit (QIAGEN, Germany) method. Gene testing was performed using Hot Start Polymerase chain reaction (PCR) to avoid non specific amplification. After amplification,...

optimization of the condition for pcr-directed sequencing of microsatellites poly adenine (a) length polymorphisms is more difficult and sensitive compared with other common sequences. replication slippage may occur for polymerase enzyme during microsatellite amplification and direct sequencing of these pcr products will be challenging for heterozygote samples. so, the aim of this study is to i...
