In the university, course scheduling and preparation for each semester can be defined as the process of determining what courses to offer, the number of sections needed for each course, assigning of a faculty member to teach each section, and allocating a timeslot and a classroom for each section to avoid clashes. The output of this activity (which is a timetable) affects every faculty member and student in various departments. This process is essentially broken down into three main stages: det...
Experimental Validation of Receiver Sensitivity for 100-Mbps Data Rates in Seawater by Using 2.4 GHz-Low-Power Electronics
Published in: International Journal on Communications Antenna and Propagation
Feb 01, 2019
This paper presents an experimental validation of the receiver sensitivity for 100- Mbps microwave data communications in a typical subsea environment. It is demonstrated that underwater microwave-based pinless connector solutions can perform under conditions that have not been explored until now. Traditional “pinned” subsea wet-mate connectors require precise rotational and angular alignment to achieve efficient and reliable connections. The demonstrated flexibility offered by pinless connecti...

Prior investigations have pointed out that an understanding of the impacts of information quality is essential to the organisation's success. Nevertheless, few investigations have analysed the impacts of information quality in a business context. This paper analyses the impacts of information quality on the decision-making process in a systematic way. To reach this goal, we suggest a pragmatic approach that allows estimation of information quality categories and dimensions. The results of the p...
High gain dielectric resonator antenna with soft cavity and soft surface for millimeter-wave applications
Published in: International Journal of Mechanical Engineering and Technology
Dec 01, 2018
In this paper, a 60 GHz high-gain dielectric resonator antenna (DRA), integrated with soft surface and capacitive soft cavity is presented. The soft surface consists of a perforated dielectric cylinder, shorting vias, and three concentric layers of metallic strips printed on both sides of the dielectric cylinder. The capacitive soft cavity comprises ten concentric planar strips printed on top of a dielectric substrate. The soft surface blocks surface wave propagation by introducing a gap wavegu...
