The purpose of this paper is mainly aimed to provide an energy security strategy for the petroleum production and processing in the grand challenges. Fault detection and diagnosis is the central component of abnormal event management (AEM) [1]. According to the International Federation of Automatic Control (IFAC), a fault is defined as an unpermitted deviation of at least one characteristic property or paramet Read More

This paper presents a novel real-time scale adaptive visual tracking framework and its use in smart traffic monitoring where the framework robustly detects and tracks vehicles from a stationary camera. Existing visual tracking methods often employ a semi-supervised appearance modeling where a set of samples are continuously extracted around the vehicle to train a discriminant classifier between the vehicles an Read More

The work of our group falls within the area of Cyber Security, which is one of Qatar's Research Grand Challenges. We are working on designing a new public key cryptosystem that can improve the security of communication networks. The most widely used cryptosystem at present (like RSA) are based on the difficulty of factorization of numbers that are constructed as product of two large primes. The security of such systems Read More

Background & Objective: Blood vessel segmentation has various applications such as proper diagnosis, surgical planning, and simulation. However, the common challenges faced in blood vessel segmentation are mainly vessels of varying width and contrast changes. In this paper, we propose a segmentation algorithm, where: (1) a histogram-based approach is proposed to determine the initial patch (seeds) and (2) on this patch, Read More

Sensors are the eyes and ears in the service of people - especially in inaccessible areas where regular maintenance or battery replacement is extremely difficult. By using thermoelectric generators, which are capable of directly converting heat flux into electrical energy, self-powered sensor systems can be established wherever temperature differences of a few Kelvin exist. After installation of the sensors, they collect Read More

Digital devices and computer software have the prospect to help children with intellectual challenges (IC) in learning capabilities, profession growth, and self-consciousness living. However, most tools and existing software applications that these children utilize are prepared without observance of their particular deficiency. We conduct an Arabic ontology-based learning system that presents automatically illustrations to characteriz Read More

In this paper we introduce and study special types of magic squares of order six. We list some enumerations of these squares. We present a parallelizable code. This code is based on the principles of genetic algorithms. A magic square is a square matrix, where the sum of all entries in each row or column and both main diagonals yields the same number. This number is called the magic constant. A natural magic squar Read More

INTRODUCTION: Minimally-invasive robotic surgery benefits the surgeon with increased dexterity and precision, more comfortable seating, and depth perception. Indeed, the stereo-endoscopic camera of the daVinci robot provides the surgeon with a high-resolution 3D view of the surgical scene inside the patient body. To leverage this depth information using advanced computational tools (such as augmented reality or colli Read More

The magnetizing characteristic of a Self Excited Induction Generator (SEIG) defines relationship between its magnetizing reactance and air-gap voltage. The characteristic is essential for steady state, dynamic or transient analysis of SEIGs as the magnetizing inductance is the main factor responsible for voltage build-up and its stabilization in these machines. In order to obtain essential data to get this characteristic the ind Read More

GRAPE-X processor is an experimental processor chip designed to achieve extremely high performance per watt. It was made using TSMC's 28 nm technology, and has achieved 30 Gflops/W. This number is three times higher than the performance of best GPGPU cards announced so far, using the same 28 nm technology. The power consumption has been the main factor which limits the performance improvement of HPC syste Read More
