ملخص الدراسة: Shrinkage in concrete is a problem which faces most of concrete structures especially in the horizontal surface that causes cracks. Drying shrinkage cracks are caused by evaporation of water of cement paste after setting, where rapid evaporation occurs. The rapid evaporation destroys the integrity of the surface and reduces its durability. To increase […]

ملخص الدراسة: Owing to the shortage of space for land reclamation in Gaza Strip, it is difficult to dispose tons of construction and demolition waste generated daily from construction activities and destroying of building during Israeli campaigns in addition to the huge amount of ex-settlements destroyed buildings. Adoption of recycled aggregate from concrete waste thus […]

ملخص الدراسة: Knowledge Management (KM) is recognized as an important weapon for sustaining and improving performance. The evaluation of knowledge management performance has become increasingly important since it provides the reference for directing the organizations to enhance their performance. This study aims to study knowledge management as an effective tool for the improvement of performance […]

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 […]

ملخص الدراسة: Oxidation ditch (OD) is a common activated sludge method for wastewater treatment. The control of oxygen supply for this type of wastewater treatment is of great importance in controlling the treatment efficiency. The European Hospital (EH) in Gaza strip suffers from the same problem. Therefore, the main objective of this research is to […]

ملخص الدراسة: This thesis presents the design of two-dimensional axis magnetic lavitation control system. An object should be able to levitate purely with magnetics fields. In order to produce a stable output and allwo movement of the levitated object between two solenoids around, a two-dimensional classical feedback control may be utilized. This is accomplished by […]

ملخص الدراسة: Passive Optical Networks (PON) have garnered interest in recent years from network providers and researchers alike owing to their tremendous economic advantages for application in last mile services and optical sensing. Optical code division multiple access (OCDMA) is a multiplexing technique that has a number of inherent advantages that make it suitable for […]

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 […]
