Considering the recent paradigm shift in education brought about by the Covid-19 pandemic, educational institutions have shifted to optimizing the use of technology for distance teaching and learning. This shift has propelled educational institutions worldwide to experiment with innovative teaching and learning methods—a de facto measure employed to ensure educational continuation previously disrupted by pandemic-related closures. Lebanon is not an atypical case; in addition to the pandemic, closures have been inflicted on the education sector by the events of October 17, 2019, and the ...

The origin of mathematical matrices lies with the study of systems of simultaneous linear equations. Today, they are used not simply for solving systems of simultaneous linear equations, but also for describing the quantum mechanics of atomic structure, and even for designing computer game graphics. Matrices are very useful due to the fact that they can be easily manipulated. We use the notation A-1 to denote the inverse of a matrix A. One of the major uses of inverses is to solve a system of linear equations. You can write a system in matrix form as AX=B, then X=A-1B. Inverses are also used in ...

The purpose of this dissertation is to study pseudo-Riemannian algebras, which are algebras with pseudo-Riemannian non-degenerate symmetric bilinear forms. The paper([1]), the authors Zhiqi Chen, Ke Liang, and Fuhai Zhu find that pseudo-Riemannian algebras whose left centers are isotropic play a key role and show that the decomposition of pseudo-Riemannian algebras whose left centers are isotropic into indecomposable non-degenerate ideals is unique up to a special automorphism. Furthermore, if the left center equals the center, the orthogonal decomposition of any pseudo-Riemannian algebra into ...

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 ...

This thesis examines the different type of agents, and how they help evolve the world around, most particularly the way business are undertaken and handled. The following work is based upon the DALIA environment, which stands for Distributed Autonomous and Linguistically Competent Agents. In this work I have extended and improved the DALIA agent negotiation aspect, where two agents are involved in an offer and counter-offer negotiations. The model presented by DALIA for the offers and counter offers ia investigated and the weak points in the negotiation paradigm are identified. A strategy is ...

The scheduling problem is one of the most challenging problems faced in many different areas of everyday life. This problem can be formulated as a combinatorial optimization problem, and it has been solved with various methods using heuristics and intelligent algorithms. We present in this research an efficient solution to the scheduling problem using two different heuristics namely Simulated Annealing and Ant Colony Optimization. A study comparing the performances of both solutions is described and the results are analyzed.

Vaccination is a preventive measure to reduce death and morbidity against infectious diseases, and has been applied effectively against most of the viral and bacterial infections around the world. Targeted campaigns against children diseases have been very effective in drastically reducing such diseases thanks to national immunization programs in both developed and developing countries. However, many individuals including parents of various ages are still reluctant to commit to vaccination and some recent fears have been increasing when it comes to vaccination more recently, especially due to ...

The world is witnessing nowadays a virus that spreads in a very fast manner and it has infected a large number of people. Countries rushed to find ways to stop this virus from spreading and to minimize the risks of getting infected. One of these ways was to integrate technology in people’s daily routine to help in containing the virus. In fact, although several countries took a lot of legal measurements and law enforcement to prevent the spread of the virus, such as wearing facial masks, social distancing, using sanitizers and other forms of hygiene supplements, there were always the need to ...

With the considerable rise of Internet users and the massive and diverse web searches, an excess of data has become available online. A recommendation model, also known as an engine, handles this massive amount of data available to find patterns that reflect user behaviors. Recommendation models have been implemented in several industries, and the most popular implementation is in the entertainment industry, specifically video streaming and on-demand platforms. There are several types of recommendation systems. In this paper, we have proposed a way to escape the loop created by the recommendation ...

There is no doubt that animation is becoming one of the biggest advertising trends and approaches in modern times. No need to wonder why! Simply put, animated advertisement gives us a video that is promotional and entertaining at the same time; leaving the consumer captured by the visuals and animation. With the relevance of animated advertisement in today’s world, this thesis aims to provide a comparative overview of animated vs non-animated advertising. The thesis shall study the “Soul Drops” animated commercial starting from scratch, to the procedures carried on until reaching the result.
