With the current rising trend in wireless based systems, applications such as video on demand, remote monitoring and surveillance are now being used in greater abundance. Coupled with this growth comes the ongoing need for improved network performance. This is due to the resource hungry nature of video data which places stringent requirements on communication networks. This study investigates performance improvement for remote surveillance applications over hybrid 2-stage disordering networks. It specifically focuses on resequencing alternatives for video data. A resequencing and batch aggregation ...

Several studies have shown a link between pesticide exposure and neurological problems. In the present study, we show the effect of twenty common pesticides (dieldrin, rotenone, endosulfan, penconazole, trifiuralin, dicofol, chloropropham, hexachlorobenzene, thiamethoxam, dimethoate, maneb, p,p' -DDE, paraquat, permethrin, chlorfenapyr, propanil, kresoxim-methyl, boscalid, triadimefon, lambda-cyhalothrin) on myelin gene expression (PLP and MBP) in oligodendrocytes. We first studied the toxicology of each chemical to determine the doses to consider by calculating the ration of dead to living ...

Taxon identification is highly needed for a wide variety of research including ecology, agronomy and medicine. As of 1970, classification of plants was introduced into computer vision techniques. Most research conducted in this area focuses on leaves due to their availability as well as their ability to discretize. The most common features researchers base their work on are shape, texture and venation. This research study proposes a dual path, dual feature model for plant leaf identification. We weigh our research on shape and venation features. Sobel operators are used for primary and secondary ...

Quantum Computers, the next wave of computing, and an emerging field in computer science have brought numerous advancements to problem solving and a quantum approach to programming a certain machine. This thesis tackles three main areas in the approach to quantum computers. First, the thesis provides a state-of-the-art review to Quantum computers/ Second it proposes a timeline for the progress of the technology and highlights the importance of early action. Finally, it focuses on the implications of such advancements on the current standards of network security. Specifically, it proposes ...

This thesis addresses the problem of analysis the Web hyperlink structure in order to locate authoritative web pages relevant to a certain query subject. In particular, we discuss the HITS algorithm, a pioneering method that exploits the web link structure in order to locate important information sources, as well as other algorithms based on HITS such as ARC and Page Rank. We experiment with different aspects of HITS, and introduce new heuristics for assigning the link weights based on textual contexts.

An extraction protocol for saponins of Styrax Officinalis plant was adopted, modified and successfully applied. The extract obtained was tested by stabilizing Oil-in-Water emulsions. Ethanol extraction and successful one-step partial purification using AB-8 adsorption column chromatography yielded positive colorimetric (Vanillin – Sulfuric Acid) TLC results. The 3D structure of the four Styrax Officinalis saponins reported in the literature were rendered for the first time, and their partitioning properties exclusively acquired using Marvin Sketch chemical drawing software. 10% w/w Sunflower Oil ...

The 80/20 rule says that 20% of the customers produce 80% of the sales; this rule indicates the existence of hidden sales potentials that must be revealed. Those hidden sales potentials can only be discovered by building acustomer profile. A smart customer profile finds the high potential targets, creates CRM strategies, and starts programs to sell the hidden targets. Shifting just a small percentage of the customers whom are not generating profit to the top group of customers generating profit adds significantly sales growth increase profits. Customer profile puts the full picture together to ...

The emerging field of wireless sensor networks combines sensing, computation, and communication into a single tiny device. Through advanced mesh networking protocols, these devices form a sea of connectivity that uses any possible communication path by hopping data from one node to another in search of its destination. While the capabilities of any single device are minimal, the collection of hundreds of sensors offers major new technological possibilities. Examples of usage scenarios for these devices are real-time tracking and security monitoring, issues that will be studied in this thesis. ...

Internet banking is somehow a new technology used by banks to interact with their customers providing them with a wide range of services available online. These services can be classified into 5 categories: informational, administrative, transactional, portal and others. However with these come new challenges, risks and threats when adapting internet banking that are either inherited from the internet or that are specific to the open banking environment. Therefore, specific security requirements to the internet banking environment should be adopted aiming to control these risks and manage ...

With the rise of the Internet, recommender systems are becoming a used solution to solve the information overload problem. These systems are like any other system, subject to noise: malicious noise that is caused by attacks and natural noise that is due to the human error. Many detection algorithms solve the noise problem. However, since natural noise and serendipity overlap in their definition, removing noise results in removing serendipity. Serendipity that is the happy surprise of finding something relevant unexpectedly is important for the issue of over personalization caused by the recommender ...
