This paper presents an investigation of practical quantum secure communication using multi-photon tolerant protocols. Multi-photon tolerant protocols loosen the limit on the number of photons imposed by currently used quantum key distribution protocols. The multi-photon tolerant protocols investigated in this paper are multi-stage protocols that do not require any prior agreement between a sender Alice and a rec Read More

Background & Objectives: There are 98,000 deaths in the US annually due to errors in the delivery of healthcare causing inpatient mortality and morbidity. Among these errors, ineffective team interaction in the operating room (OR) accounts for one of the main causes. Recently, it has been suggested that developing a conceptual model of verbal and non-verbal exchanges in the OR could lead to a better understanding of th Read More

Qatar has a high potential to develop renewable energy generating systems spatially through solar and wind-based technologies. Although, substantial initiatives have been undertaken in Qatar to reduce the high per capita emissions of the Greenhouse Gases (GHG), solar and wind-based energy generation can also significantly contribute to the mitigation of climate change. The mean Direct Normal Irradiance (DNI) of Qat Read More

Email is one of the most widely used forms of written communication over the Internet, and its use has increased tremendously for both personal and professional purposes. The increase in email traffic comes also with an increase in the use of emails for illegitimate purposes to commit all sort of crimes. Phishing, spamming, email bombing, threatening, cyber bullying, racial vilification, child pornography, viruses and malware pr Read More

The development and improvement of a model that can provide accurate estimates of the power produced by a photovoltaic system is useful for several reasons. A reliable model contributes to the proper operation of a photovoltaic power system since any deviations between modeled and experimental power can be flagged and studied for possible problems that can be identified and addressed. It is also useful to grid oper Read More

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
