for many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. however, an issue that has rarely been studied is the speed of these methods. considering the computer hardware limitations, it is necessary for these methods to run in high speed. one of the methods to increase the processing speed is to use the computer pa...

We report nonlocal spin injection and detection experiments on mesoscopic Co-Al2O3-Cu spin valves. We have observed a temperature-dependent asymmetry in the nonlocal resistance between parallel and antiparallel configurations of the magnetic injector and detector. This strongly supports the existence of a nonequilibrium resistance that depends on the relative orientation of the detector magneti...

The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV ...

visual representations are those that use conventional symbols to represent the relevant elements of a problem’s cover story. For example, the top portion of Figure 1 illustrates the conventional circuit symbols of the following problem: “Consider two resistors with resistance values R1 6 and R2 12 connected in parallel to a voltage source with V 9 V. Find the total resistance of this circuit.”...

Abstract Adjusting the grain growth orientation may be a feasible way to improve oxidation resistance. In this work, textured Ti 3 (SiAl)C 2 ceramic was successfully fabricated via spark plasma sintering technique. The crystal and microstructure were investigated by XRD combined with EBSD. behavior of at 1000–1300 °C for 10 h. results showed that significantly anisotropic surface parallel compr...

We investigated the association between prescribing antimicrobial agents and antimicrobial resistance of Streptococcus pneumoniae among children with acute otitis media in southern Israel. During a 6-year period, all prescriptions of a sample of approximately 20% of Jewish and Bedouin children <5 years of age were recorded and all pneumococcal isolates from middle ear fluid were collected. Alth...
