Software systems find themselves working in an environment that forces them to be undergoing rapid change, and with each change to provide better services. In some systems, the functional requirements are easy to provide, it is the non-functional ones that are difficult. Yet with the ever changing requirements comes the demands for better quality and performance. For software system to achieve…

Purpose: the main purpose of the present study is to compare Internet addiction, feeling of loneliness, and educational progress between two groups of students of Oshnavieh Payam-e-Noor University including healthy and at-risk students. Methods: for the purpose of this study 260 subjects (143 female and 111 male students) participated which were selected by proportional random method. The rese…

Electrical Discharge Machining (EDM) is a well-established noncontact machining technique for manufacturing geometrically complex shapes on hard but electrically conductive materials that are extremely difficult-tocut by conventional processes. EDM has low material removal rate and Powder-Mixed Electrical Discharge Machining (PMEDM) is one of the latest techniques that has emerged to improve ma…

This research work verified the input solar irradiance and average power output per day of a 10W polycrystalline silicon solar panel (PsSp) and a 10W gallium arsenide (GaAs) solar panel, both of dimension 350x290x25mm3, fill-factor 0.7 in the four different quarters of the year 2013. The average power output in KWh/m2 per day in four quarters of the year were compared to determine which quarte…

The cadmium sulphide (CdS) is an important II–VI semiconductor (Eg = 2.42 eV, 515 nm) at room temperature with many excellent physical and chemical properties. It has promising applications in multiple technical fields including photochemical catalysis, gas sensor, detectors for laser and infrared, solar cells, nonlinear optical materials, various luminescence devices, optoelectronic devices…

Gamma ray radiation alert monitoring 4 was used to determine the variation of terrestrial gamma radiation levels in some parts of Ogun state, South Western Nigeria. The study revealed that there is variation in the value of absorbed dose on ground surface and a metre above the ground surface. The value recorded on the ground for sedimentary terrain, basement complex and suspected transition zon…

The degree of dependence of power delivered by a solar panel on input solar irradiance was examined with a 10watt polycrystalline silicon (Si) solar panel and a 10watt polycrystalline gallium Arsenide (GaAs) solar panel, each at a fill-factor of 0.7.The research was carried out at Ilesa city located at coordinates 7037′0″N 4043′00E / 7.616670N4.716670E, in Osun State of Nige…
