Background: A spiral phase rear mounted masked scheme is proposed based on Gyrator Transform (GT) to enhance the security contribution of second lens of the existing Double Random Phase Encoding (DRPE) system by modulating the phase of the output obtained in output plane. An additional third layer of Spiral Phase Mask (SPM) is included in the output plane in the same 4f system. Objective: To develop a symmetri Read More

Background: The Planar Inverted-F Antenna (PIFA) is most widely used for wireless communication applications due to its unique properties as low Specific Absorption Rate, low profile geometry and easy fabrication. In literature a number of multiband PIFA designs are available that support various wireless applications in mobile communication, satellite communication and radio frequency field. Methods: In this paper, a mini Read More

Background: The last three decades were marked by a spectacular evolution of CPUs. Both cores number on chip and shared Low Level Cache (LLC) size are increasing what makes LLC the bottleneck's system. One major weakness of future cache memory hierarchies will be to carry out memory blocks availability for vertical requests, with no consideration to horizontal proximity to cores. Simulations show that some LLC Read More

Background: The World Wide Web houses an abundance of information that is used every day by billions of users across the world to find relevant data. Website owners employ webmasters to ensure their pages are ranked top in search engine result pages. However, understanding how the search engine ranks a website, which comprises numerous web pages, as the top ten or twenty websites is a major challenge. Although Read More

Background: In this paper, a Convolutional Neural Network (CNN) to learn safe driving behavior and smooth steering manoeuvring, is proposed as an empowerment of autonomous driving technologies. The training data is collected from a front-facing camera and the steering commands issued by an experienced driver driving in traffic as well as urban roads. Methods: This data is then used to train the proposed CNN to fa Read More

Background: DNA and Protein sequences of an organism contain a variety of repeated structures of various types. These repeated structures play an important role in Molecular biology as they are related to genetic backgrounds of inherited diseases. They also serve as a marker for DNA mapping and DNA fingerprinting. Efficient searching of maximal and super maximal repeats in DNA/Protein sequences can lead to many Read More

Background: In just last two-years most of the world's video data has been created by the digital devices like smartphone, surveillance cameras, and wireless sensor networks. These days the IEEE 802.11n enabled devices for Wireless Local Area Networks (WLANs) are being used to achieve higher throughput at the Medium Access Control (MAC) layer. Methods: In this research, the Dynamic Aggregation Mechanism (DAM) alg Read More

Background: Social media texts are often highly unstructured in accordance with the presence of hashtags, emojis and URLs occurring in abundance. Thus, a sentiment or emotion analysis on these kinds of texts becomes very difficult. The difficulty increases even more when such texts are in local languages like Arabic. Methods: This work utilizes novel deep learning architectures in the form of character-level Conv Read More
