This paper introduces a lightweight wideband planar antenna with an antenna array configuration for microwave head imaging. The designed antenna is composed of a double hollow rectangular-shaped patch and with the slotted ground. Its measurements are small: 0.28λ Â 0.24λ Â 0.006λ, where λ is the lowest operating frequency's wavelength. The design process has been completed using CST and then fine-tune the parameters of the architecture structure to accomplish the ideal bandwidth. The antenna is manufactured and measured in order to test antenna properties. The prototype was being used for brain screening than with the Hugo-head model. With adequate impedance matching, the antenna meets an operational bandwidth of 1.82 GHz (1.22-3.04 GHz) with an overall peak gain of 5 dBi with a stable radiation property.Fidelity factors both for face-to-face and side by side alignment are 92.7% and 83.75%, respectively, indicating that the antenna had a little signal interruption. To determine the backscattered signals of the antenna with Hugo-head phantom, a nine-antenna array-based setup is assumed, with one antenna serving as a transmitter and the remaining eight receiving the dispersed signals.

This is a survey of the studies identified with the potential effect that the new changes of Kingdom of Saudi Arabia's vision for 2030 with a consideration on the Ministry of Education (MOE) in Saudi Arabia will influence the selfappraisal of Saudi understudies/students by their family's interest or participation. A few studies indicate strong proof that the developments of the Kingdom of Saudi Arabia's 2030 vision for education to enhance the expanded inclusion of families in the lives of their school-age kids. The impression of instructors and understudies, in addition to their parts in self-evaluation are considered alongside this investigation of' the approaches/techniques utilized by educators and the instructional procedures executed in the KSA 2030 Project which will lead towards world class learning for Saudi Arabian understudies/students and spring boarded by the interest of Saudi Arabian families in their kids' lives. This research article is about a hypothetical investigation and nitty gritty examination of the way of educator's evaluations which will prompt an establishment for a discourse of models taking into account hypothesis for appraisal purposes in instruction/education and sublime teaching method all through Saudi Arabia now and in future and how the Saudi Arabian families and their contribution in their kids' tutoring will prompt enhanced instructors' input/feedback for students understudies.

In recent times there has been a growing trend for more information and knowledge to enhance learning based on cognitive load theory with increased use of Educational Technology based on Web ICT with online education resources. There are also various instructional and expert models being developed for the adaptive e-learning mechanisms as required for effective learning based on Genetic, Neural Networks, Swarm Intelligence and other Bio inspired algorithms or Evolutionary algorithms. Computational Intelligence or Artificial Intelligence has also established new paradigms for Learning Systems in creating virtual class rooms in the physical absence of tutors. It is also possible to create virtual labs on which students that are registered can carry out their experiments from remote with Interactive Intelligent Tutoring Systems.The current paper will develop a problem model using Markov Chain and greedy algorithms for Tutor or Instructor -Student interactive model for virtual labs and virtual class rooms which will be built on the Deep Belief Network architecture as a novel approach for state-of-art courses related to Energy and Wireless Communication for Higher Education proposed as part of Inter University Research Groups. Further, a Bio inspired Differential Evolution algorithm will be deployed for the virtual labs and virtual class rooms to meet the specific learning requirements for the Instructor-Student interactions specific to this E-learning platform.The proposed study will help improve the learning environment to stimulate creativity and innovation as envisaged by the Ministry of Education under the Saudi Arabia Vision 2030 and will help in moving towards creating an international benchmark for deploying innovative E-learning mechanisms for Higher Education.

Security is an illusion unless you are hacked. Attacks in the Cloud have more catastrophic and destructive impact on the organizations than the user might expect. As attacks are constantly evolving and making it difficult to defend. Most of the organization will try to check their devices in the cloud to protect against viruses with traditional security measures like antiviruses, or firewall thinking it secures across different attacks, but with a wide range of change in attack pattern organizations have exposed to significant operational and business consequences, not to mention public embarrassment. In this paper, we conducted the survey on DDOS (Distributed Denial of Service) attacks research work and analyzed prevention and detection methods used for DDOS attacks in the cloud. We found that there is a good amount of research scope in detecting and preventing slow client application layer attacks in the cloud.
