In this document we present an overview of Transactional Memory models, as well as a comparison to traditional parallel frameworks. In this context, we follow with an analysis on the problem of self-tuning concurrency control in transactional memory, where different mechanisms are used to predict and adjust an application’s concurrency level with respect to available parallelism. We are particu...

The problem of determining the optimal number of clusters is important but mysterious in cluster analysis. In this paper, we propose a novel method to find a set of candidate optimal number Ks of clusters in transactional datasets. Concretely, we propose Transactional-cluster-modes Dissimilarity based on the concept of coverage density as an intuitive transactional inter-cluster dissimilarity m...

Traditional association rules are mainly concerned about intra-transactional rules. In time series analysis, intra-transactional association rules can only reveal the correlations of multiple time series at same time. It is difficult to forecast the trend of time series. In this paper, it is studied the mining problem of inter-transactional association rules in time series with which the trend ...

OBJECTIVE This study sought to determine the prevalence of transactional sex among university students in Uganda and to assess the possible relationship between transactional sex and sexual coercion, physical violence, mental health, and alcohol use. METHODS In 2010, 1954 undergraduate students at a Ugandan university responded to a self-administered questionnaire that assessed mental health,...

The overall aim of the present thesis was to enhance and revive the practical understanding of the active ingredients in Transactional Analysis Psychotherapy (TA) and to define and lay down elements of TA, which makes it a distinct and replicable method of treatment. The thesis includes three empirical studies of a videotaped one-year long TA Group Therapy with 10 clients. Three different key a...
