ملخص الدراسة: Various solid wastes that are emerged from steel plants are blast furnace slag, blast furnace flue dust, sludge and mill particle. Therefore, use of waste materials in road pavements is nowadays considered not only as a positive option in terms of sustainability, but also as an effective option in means of providing enhanced […]

ملخص الدراسة: Temperature is one of the most important factors affecting the design and performance of pavement. Temperature variations within the asphalt pavement structure contribute in many different ways to distress and possible failure of that structure. The structural performance of pavements is highly dependent on temperatures to which these pavements are exposed. For a […]

ملخص الدراسة: Recycling is considered to be one of the most important bases of sustainability. Almost all the products we utilize, whether they are metal, concrete, plastic, wood, or even glass, will eventually turn into wastes that must be disposed. The best way to deal with these wastes is to recycle and reuse them as […]

ملخص الدراسة: An important issue of microgrid is to share the load demand, the structure of the research. Two parallel inverters with load system are presented. The paralleled inverters need to work in grid-connected mode and stand-alone mode, and to switch seamlessly between the two modes. For a networked microgrid configuration with linear and nonlinear […]

ملخص الدراسة: Cardiovascular diseases are major causes of morbidity and mortality in the developed countries. One of the cardiac diseases, bradycardia sometimes results in fainting, shortness of breath, and if severe enough, death. It is defined as a heart rate less than 60 bpm. Implantable cardiac devices such as pacemakers are widely used nowadays. They […]

ملخص الدراسة: Renewable energy sources play an important role in electric power generation. There are various renewable sources, which are used for electric power generation, such as solar energy, wind energy, geothermal etc. Solar energy is a good choice for electric power generation, which is viewed as clean and renewable source of energy for the […]

ملخص الدراسة: The availability and continuity of electrical power sources in sensitive building like hospitals is very important issue. Due to the unstable power grid conditions in Gaza Strip, inefficient amount from the main electrical power supplied by public grid, and risk of electrical power fault occurring daily, sensitive building are provided with extra alternative […]

ملخص الدراسة: Inverters are used widely nowadays because of many of renewable energy source available. These energy source can provide DC voltage like solar panels and the real need of storage energy devices as batteries which also provide DC voltage. Traditional DC-AC inverters have main limitation, this limitation is that AC output voltage is limited […]

ملخص الدراسة: Renewable energy sources are usually connected to the power grid via power converters. Zeta converters are very important for microgrid and smart grid applications, and are used in other applications such as power quality improvements, power factor correction, and industrial applications. Choosing Zeta converter alone is not enough since the converted output voltage […]

ملخص الدراسة: Phased array antenna technology is emerging as new way to deal with the growing demand for more powerful, cost effective and highly efficient wireless systems. This thesis presents phased array antenna at Ku-band for satellite system applications with steering capability to receive signals from different satellites. The proposed feeding structure consists of hybrid […]
