We consider a leader election algorithm in which a set ofdistributed 'ob· jects (people, computers, elc.) try to identify one object as their leader. The election process is randomized, that is, at every stage of the algorithm. those objects that survived so far flip abiased coin, and those who received, say a tail. survive for the next round. The process .continues until only one objects remai...

B cell entry to lymph nodes and Peyer's patches depends on chemokine receptor signaling, but the principal chemokine involved has not been defined. Here we show that the homing of CXCR4-/- B cells is suppressed in CCL19 (ELC)- and CCL21 (SLC)-deficient paucity of lymph node T cells mice, but not in wild-type mice. We also find that CXCR4 can contribute to T cell homing. Using intravital microsc...

The European Landscape Convention (ELC) has directed the landscape classification towards character analysis. analysis provides a character-based that can combine different values or variables and be applied at scales to define landscapes of each country forces on landscape. In this study, Kapısuyu Basin Küre Mountains National Park, which is one hot spots in world terms natural quality, was cl...

Together with quality power supply criteria, Composite Power System (CPS) reliability is also one of the important aspects deciding security CPS for a given load demand. In current paper, evaluated. The Newton Raphson (NR) approach implemented in Simulation Engineering (PSSE) software to take into account, flows, then available points, evaluate CPS. NR Method was by considering different contin...

This study aims at analyzing the English as a foreign language (EFL) learners’ and teachers’ perception toward use of online videos in EFL classes. The current used mixed method to answer question which is: What is learners teachers classes? It includes both quantitative qualitative techniques, namely questionnaire an interview. To get required data study, researcher collected information by di...

Change detection techniques are widely diffused to derive basic information in the analysis of land cover transformations. Some difficulties in multi-date imagery treatment persist in remote sensing applications because of errors due to noise, to environmental conditions and to geometric and radiometric distortions introduced during the acquisition or transmission phases of satellite systems. S...
