Memetic algorithms (MAs) are hybrid evolutionary algorithms (EAs) that combine global and local search by using an EA to perform exploration while the local search method performs exploitation. Combining global and local search is a strategy used by many successful global optimization approaches, and MAs have in fact been recognized as a powerful algorithmic paradigm for evolutionary computing....

In heterogeneous distributed computing systems, partitioning of the application software into modules and the proper allocation of these modules among dissimilar processors are important factors which determine the efficient utilization of resources. This paper presents a new heuristic model, the HMLM/SA, which performs static allocation of such program modules in a heterogeneous distributed co...

Systems enabling to drive automatically are being introduced on the market. When using this technology, drivers are in need for interfaces which support them with supervision of the automated control. Assessment of Situation Awareness (SA) which drivers are able to gain while using such interfaces, is important. Based on comparison between SART and SAGAT measurement techniques within a simulato...

Background Incidence of anomalous coronary anatomy (ACA) in caucasian and middle eastern patients with ventricular septal defect (VSD) and pulmonary stenosis (PS) is between 29%. Prevalence of ACA in South Asian (SA) patients is unknown. Patients with VSD and PS may have Tetrology of Fallot (TOF) or Double Outlet Right ventricle (DORV) morphology. This study looks at the prevalence of ACA in SA...

a knowledge of physical and aerodynamic properties of agricultural crops is important and essentially required for the design and development of a crop's harvesting and post-harvesting equipments. in the present research, experiments were conducted to determine physical and aerodynamic properties of fars province pinto bean namely: kernel size and shape (length, width, thickness, projected...

OBJECTIVES To quantify fatigue risk and sleepiness among anesthesia residents in Saudi Arabia (SA). Methods: Between April 2014 and April 2015, all anesthesia residents training in western, central, and eastern regions in SA were invited to fill a survey. We conducted a cross-sectional self-reporting survey that included demographic data, the Epworth sleepiness scale (ESS), and 2 other scales t...

One of the key assumptions in Endsley’s three-level Situation Awareness (SA) model is the critical role of mental models in the development and maintenance of SA. We explored a prescriptive way of modeling this essential mental process of the fire incident commanders’ fire ground assessment. The modeling was drawn from the Fast and Frugal Heuristics (FFHs) program, given the strong parallels be...

Previous spreadsheet inspection experiments have had human subjects look for seeded errors in spreadsheets. In this study, subjects attempted to find errors in human-developed spreadsheets to avoid the potential artifacts created by error seeding. Human subject success rates were compared to the successful rates for error-flagging by spreadsheet static analysis tools (SSATs) applied to the same...

South Africa (SA) has the highest number of women infected with HIV and AIDS during pregnancy, which results in more than 70 000 infected babies being born each year AIDS is the major contributor to maternal and child morbidities and mortalities in the country. To combat this, the SA government has developed a national policy to prevent mother-to-child HIV transmission (PMTCT). However, for eff...
