A Rectangular Dielectric Resonator Antenna (RDRA) is theoretically analyzed using the Conventional Dielectric Waveguide Model (CDWM), numerically simulated using the High Frequency Structure Simulator (HFSS) based on the Finite Element Method (FEM) software package and experimentally investigated with the consideration of the fundamental mode TE 111. Antenna parameters under investigation inclu...

The solid waste management (SWM) represents one of the most important challenges worldwide in current period. Also, it contributes to large negative effect on three aspects sustainability which are environmental, social and economic sustainability. Approximately 50% total annual global generated (SW) is from construction demolition (CDW). case CDW Egypt has become a major challenge, encounters ...

Working memory depends on communication between the hippocampus and the prefrontal cortex (PFC); however, the neural circuitry that mediates interactions between these brain areas has not been well characterized. Two candidate structures are the thalamic reuniens (RE) and rhomboid (Rh) nuclei, which are reciprocally connected with both the hippocampus and PFC. These known anatomical connections...

nowadays, it’s very usual to use these models in almost all sciences. use of these models has provided quick, appropriate and economic answers to many questions. modeling is developing in different fields of agriculture, including irrigation and drainage. field tests are useful to determine and analyze the different irrigation management but there are significant limitations. the most important...

It is quite common that guides are introduced to suppress the information spreading in modern society for different purposes. In this paper, an agent-based model is established to quantitatively analyze the impacts of suppressing guides on information spreading. We find that the spreading threshold depends on the attractiveness of the information and the topology of the social network with no s...

For the travel industry, technology, digitalization, and connectivity are factors of significant importance. We proposed a city guide app (CGA) model in this research. The general tourist information is enormous, but it essential to know interest for travelers useful mobile applications. used an online survey detect kind information. interviewees were young people aged 20 24 from Romania who at...
