In the last twenty years, many algorithms and heuristics were developed to find solutions in constraint networks. Their number increased to such an extent that it quickly became necessary to compare their performances in order to propose a small number of “good” methods. These comparisons often led us to consider FC or FC-CBJ associated with a “minimum domain” variable ordering heuristic as the...

A combined application of independent component analysis and projective filtering of the time-aligned ECG beats is proposed to solve the problem of fetal ECG extraction from multi-channel maternal abdominal electric signals. The developed method is employed to process the four-channel abdominal signals recorded during twin pregnancy. The signals are complicated mixtures of the maternal ECG, the...

We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for en...

This study investigated the influence of genetic factor and personality on leadership role occupancy among a sample of male twins. Identical twins (n =238) who share 100% of their genetic background were compared with fraternal twins (n =188) who are expected to share only 50% of their genetic background. Results indicated that 30% of the variance in leadership role occupancy could be accounted...

Reliable and accurate veri!cation of people is extremely important in a number of business transactions as well as access to privileged information. Automatic veri!cation methods based on physical biometric characteristics such as !ngerprint or iris can provide positive veri!cation with a very high accuracy. However, the biometrics-based methods assume that the physical characteristics of an in...

The prevalence of temporal landmarks has been revealed in a wide range of tasks associated with autobiographical memory, such as recall and dating of personal events. The author examined 3 types of events that have usually been considered landmarks: flashbulb memories, 1st experiences, and reference points in personal histories. The differences between landmark events and nonlandmark events are...

Many approaches are currently being considered to develop digital twins and integrated frameworks. These concentrate on an industrial sector or a single product, with the obvious risks of lack interoperability at differing levels abstraction. However, unified approach is required truly realize benefits achievable their current stage development. We present proof-of-concept case studies where tw...

Off-site construction is an innovative type of with the philosophy standardizing process and deploying latest technological enablers. Many technologies, such as Building Information Model (BIM), Internet Things (IoT), etc., are concerned virtual representation manipulation physical site. However, a holistic view off-site processes lacking in exploration advances, resulting inconsistency when ap...
