Gas detection is one of the major processes that has to be taken into consideration as an important part of a monitoring system for production and distribution of gases. Gas is a critical resource. Therefore, for safety reason, it is imperative to keep monitoring in real time all parameters such as temperature, concentration and mixture. The presented research in this abstract on gas identification is part of an ongoing research pr Read More

I.BACKGROUND & OBJECTIVES Owing to its high-bandwidth, robustness to EMI, and operation in unregulated spectrum, free-space optical communication (FSO) is uniquely qualified as a promising alternative or complementary technology to fiber optic and wireless radio-frequency (RF) links. Despite the vibrant advantages of FSO technology and the variety of its applications, its widespread adoption has been hampered Read More

Secure communications is one of the key challenges faced in the field of information security as the transmission of information between legitimate users is vulnerable to interception by illegitimate listeners. The state-of-the -art secure communication schemes employ cryptographic encryption methods. However, the use of cryptographic encryption methods requires generation, distribution and management of keys to encrypt t Read More

Islamic web content offers a very convenient way for people to learn more about Islam religion and the correct practices. For instance, via these web sites they could ask for fatwas (Islamic advisory opinion) with more facilities and serenity. Regarding the sensitivity of the subject, large communities of researchers are working on the evaluation of these web sites according to several criteria. In particular there is a huge Read More

With the recent rise of social media, Arabic speakers have started increasingly using dialects in writing, which has constituted research in dialectal Arabic (DA) as a field of interest in natural language processing (NLP). DA NLP is still in its infancy, both in terms of its computational resources and in its tools, e.g. lack of dialectal morphological segmentation tools. In this work, we present a 2.7M-token collection of monolingual corpo Read More

Smart watches have been available for quite some time now. However,with the announcement of"Apple Watch"by Apple Inc., a strong buzz about smart watches has been created. A highly anticipated success of Apple watches can also be linked to an expected increase in the smart watch market in the very near future. Apart from Apple, other big companies such as Sony, Motorola, Nike have their own brand of smart watc Read More

The energy utilization efficiency of commercial photovoltaic (PV) pumping systems can be significantly improved by employing many MPPT methods available in the literature such as the constant voltage, short-Current Pulse, Open Voltage, Perturb and Observe, Incremental-Conductance and non-linear methods (Fuzzy Logic and Neural Networks). This paper presents a detailed experimental study of the two Read More

To get readers of international news stories interested and engaged, it is important to show how a piece of far-away news relates to them and how it might affect their own country. As a step in this direction, we have developed a tool to automatically create textual relations between news articles and readers. To produce such connections, the first step is to detect the countries mentioned in the article. Many news sites, incl Read More

sPCA: Scalable Principle Component Analysis for Big Data Web sites, social networks, sensors, and scientific experiments today generate massive amounts of data i.e Big Data. Owners of this data strive to obtain insights from it, often by applying machine learning algorithms.Thus, designing scalable machine learning algorithms that run on a cloud computing infrastructure is an important area of research. Many of these algo Read More
