Background: Gland is a prevalent organ in a human body, synthesizing hormones and other vital substances. Gland morphology is an important feature in diagnosing malignancy and assessing the tumor grade in colorectal adenocarcinomas. However, a good detection and segmentation of glands is required prior to the extraction of any morphological features. Objectives: The aim of this work is to generate a glandular map Read More

A significant research effort has been dedicated in developing smartgrids in the form of interconnected microgrids. Their use is especially suitable for integration of solar generated electricity, due to the fact that by separating the electrical grid into smaller subsections, the fluctuations in the voltage and frequency that occur, can be to, a certain extent, isolated from the main grid. For the new topology, it is essential to optimiz Read More

Nowadays, Nuclear Medicine becomes a potential research field of a growing importance at the universities. This fact can be explained, on one hand, by the increasing number of purchases in medical imaging devices by the hospitals, and, in other hand, by the number of PhD students and researchers becoming interested to medical studies. A Positron Emission Tomography (PET) system is a functional medical imaging tech Read More

The classification of Islamic content on the Internet is a very important step towards authenticity verification. Many Muslims complain that the information they get from the Internet is either inaccurate or simply wrong. With the content growing in an exponential way, its manual labeling and verification is simply an impossible task. To the extent of our knowledge, no previous work has been carried out regarding his task. I Read More

The rapid development of biosensors and wireless communication devices brings new opportunities for Body-Centric Wireless Networks (BCWN) which has recently received increasing attention due to their promising applications in medical sensor systems and personal entertainment technologies. Body-centric wireless communications (BCWCs) is a central point in the development of fourth generation mobile commun Read More

In this project, we address the problem that a research funding agency may face when matching potential reviewers with submitted research proposals. A list of potential reviewers for a given proposal is typically selected manually by a small technical group of individuals in the agency. However, the manual approach can be an exhausting and challenging task, and (more importantly) might lead to ineffective selections t Read More

Static Team Theory is a mathematical formalism of decision problems with multiple Decision Makers (DMs) that have access to different information and aim at optimizing a common pay-off or reward functional. It is often used to formulate decentralized decision problems, in which the decision-making authority is distributed through a collection of agents or players, and the information available to the DMs to implement their act Read More

A remote laboratory containing a specially designed experiment was built to demonstrate and visualize the characteristics of wire-shape shape memory alloys (SMAs). In particular, the unit helps the study of the hysteretic behavior of SMAs as well as how the electrical driving frequency changes the hysteresis loop. One such SMA remote experiment with a novel unified framework was constructed at the Texas A&M Unive Read More

This paper analyzes the performance of a hybrid control access scheme for small cells in the context of two-tier cellular networks. The analysis considers MIMO transmit/receive arrays configuration that implements transmit antenna selection (TAS) and maximal ratio combining (MRC) under Rayleigh fading channels when the interfering sources are described using Poisson field processes. The adopted models of aggregate int Read More

Fault tolerance techniques should let the program continue servicing in spite of the presence of errors. They are of primary importance mainly in case of mission-critical systems. Their eventual failure may produce important human and economic casualties. For these reasons, researchers have assigned the software reliability as an important research area in terms of checking its design and functionality. As a matter of fact Read More

Mobile robots provide automated solutions for a range of tasks in industrial settings including but not limited to inspection. Our interest is automated inspection tasks including gas leakage detection in natural gas processing facilities such as those in Qatar. Using autonomous mobile robot solutions remove humans from potentially hazardous environments, eliminate potential human errors from fatigue, and provide d Read More

Power lines (PLC), mainly dedicated and optimized for delivering electricity, are, nowadays, used to transfer data. Its low cost and wide coverage makes it one of the pivotal technologies in building up smart grid. The actual role of PLC technology is controversial while some preconize that PLC systems are very good candidates for some applications others discard it and look at wireless as a more elaborated alternative. It is obvi Read More

Opinion mining is becoming of high importance with the availability of opinionated data on the Internet and the different applications it can be used for. Intensive efforts have been made to develop opinion mining systems, and in particular for the English language. However, models for opinion mining in Arabic remain challenging due to the complexity and rich morphology of the language. Previous approaches can be categorize Read More

Cyber security is moving from traditional infrastructure to sophisticated mobile infrastreless threats. We believe that such imminent transition is happening at a rate exceeding by far the evolution of security solutions. In fact, the transformation of mobile devices into highly capable computing platforms makes the possibility of security attacks originating from within the mobile network a reality. All recent security report emphas Read More

Annotation Guidelines for Non-native Arabic Text in the Qatar Arabic Language Bank The Qatar Arabic Language Bank (QALB) is a corpus of naturally written unedited Arabic and its manual edited corrections. QALB has about 1.5 million words of text written and post-edited by native speakers. The corpus was the focus of a shared task on automatic spelling correction in the Arabic Natural Language Processing Worksh Read More

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
