    The aim of data mining as a scientific research is developing methods to analyze large amounts of data in order to discover interesting regularities or exceptions. Typical problems, which should be resolved during developing effective data mining algorithms, arise from the large sizes of both: The data sets used in the data mining process and the patterns results sets (for example in rules) which form discovered knowledge. Scientific researchers are oriented to find the most advantageous (i.e. most effective) solutions both during the data preparation stage and exploration and finally post- ...

    The Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a test used to differentiate between humans and machines. In this thesis, we have implemented a deep neural network architecture to automatically recognize CAPTCHAs. The main idea behind this thesis is to test the reliability of test-based CAPTCHAs in differentiating between humans and machines. We utilized convolutional neural networks instead of the conventional strategies of CAPTCHA breaking which, typically, use segmentation techniques. Our model is comprised of 8 layers to learn textbased images; ...

The main part of this study is the texture analysis since it is the hardest problem in common. As a start, 4 different techniques in texture analysis have been introduced, the Spatial Gray-level Dependence Matrices (SGLDM), The Fourier Power Spectrum (FPS), The Gray- Level Difference Statistics (GLD), and Law's Texture Energy Measure (TEM). Each of these methods have been discussed ...
  • Hatoum, Oussama (Notre Dame University-Louaize, 2004)
    This thesis aim is defining a new meaning for microprogramming as we know it. Microprogramming was seen from two different views. In commercial applications microprogramming was treated primarily as an emulation tool. This allowed systems such as the IMB system/386 to implement both backward and forward compatibility. In military applications microprograming was considered as a tool for building optimized and fault tolerance control units. Dynamic and user microprogramming are usually used to refer to the same concept. In this thesis we will make a clear distinction between the two terms. User ...
  • Keyrouz, Karam (Notre Dame University-Louaize, 2018-02)
    Nearly 1.3 million people die in road crashes each year and 20 to 50 million people are injured or disabled. This made automated car accident prevention and detection a topic of extreme interest worldwide. However, as of yet, the different systems that have been proposed and implemented, do not take underdeveloped countries into account despite their greater need. This is probably due to the fact that this problem is already hard enough to tackle without adding more constraints to it. In addition, these constraints have not been identified and lack of awareness regarding the importance of this ...
  • Shammas, Shady J. (Notre Dame University-Louaize, 1999)
    Over the last few years, LAN technologies have been driven by the need to support an increasing number of users as well as bandwidth intensive applications. As new and existing network applications evolve to embrace high-resolution graphics, video and other rich media types, pressure is growing at the desktop, the server, the hub and the switch for increased bandwidth. All this has led to new network protocols needed to support the amount of information required. In this thesis, we will briefly review conventional networking protocols and internetworking devices. Then we present a table comparing ...

  • Faddoul, Fady S. (Notre Dame University-Louaize, 2004)
    Software components enable practical reuse of software parts and amortization of investments over multiple applications. Software components are binary units of independent production, acquisition that are combined together to form a functioning system. Building solution by combining bought and made components improves quality and supports rapid development, leading to short time to market. For these reasons, component technology is expected by many to be the corner stone of software in the year to come. Even though component software is a very promising way of building applications, it is very ...

    This thesis uses the link structure of the World Wide Web as a basis to create better search engines. It focuses on the HITS algorithm, which was the first algorithm to up the link topology. HITS is implemented with slight modifications and tested with variations of its input parameters. It is also used in order to discover emerging communities in cyberspace. Other related algorithms, which use the link structure of the web as an undirected graph are described and compared with HITS. Finally, an attempt to combine link-based with text-based analysis in order to create more accurate search methods ...

    Enterprise resource planning – ERP – is among the latest technologies that companies have undertaken. Typically it is a software package that has a centralized database for several modules; these modules could be customized based on the organization’s needs. Since the cost of an ERP implementation is considered to be very high, it is critical for organizations to make it a success and start having return on their investment. But what makes an ERP implementation project successful? How to evaluate its success? These are the questions addressed by the thesis. Answering these questions, a research ...
  • Kamouh, Walid A. (Notre Dame University-Louaize., 2000-07)
    The internet is once again suffering from its own success. Since 1995, there has been a massive increase in demand for internet services, resulting in an exponential growth of the Internet. We have entered now an era where the users of the Internet are unable to obtain the bandwidth needed to support their applications, and they are experiencing high packet loss. Packet loss problem arises whenever the number of packets arriving at a given router is much higher than its buffering space. The main goal of this thesis is to find adaptive schemes capable of optimizing the communication network ...

    Geographic Information Systems (GIS) have gone a great way since it has started as a science. GIS is making headlines in a number of disciplines and, through its advancement, has improved our ability to model our real world. In the past years the need to support the storage and retrieval of dynamic changes, which occur to our data, has increased which consequently led to the interest in spatio-temporal behavior in GIS. These years have also seen the birth of several spatio-temporal data Models, whose aim is to support this spatio-temporal behavior. The main aim behind Spatio-Temporal support is ...

    UML is an acronym for Unified Modelling Language. It has become de facto the standard for the object-oriented software analysis and design stages in software development. UML is a visual modelling language, and it consists of a set of diagrams. Static diagrams are used to depict static structure of a program, where is dynamic diagrams specify how the control flow(s) of the program should behave. The examples of behavioral diagrams are a Sate diagram, which describes the behavior of objects of a given class, and a Sequence diagram, which describes inter-object interactions in a given scenario. A ...
  • Ibrahim, Rita Jack (Notre Dame University-Louaize, 2000-06)
    In this thesis, we investigate the use of neural networks for solving the Traveling Salesman Problem (TSP). First, we review the main elements of the theory of NP-completeness. Then, we explain what makes some problems computationally intractable. We review some heuristic approaches used to provide near-optimal solutions to NP-complete problems. Then, we introduce the topic of neural networks and describe some of the most popular neural network models. We pay a special attention to a recent model, named the Hybrid Neural Network model (HNN), used for solving optimization problems and the Hybrid ...
