The need to secure and control access to rooms in premises has shifted from allowing some people to enter a room to giving permission to specific persons to access a room and recording who entered the room and the time they spent in it. With such need for higher security in mind, we design an access control system for controlling physical access of people to locations or to specific units in these locations.

Show moreThe need to secure and control access to rooms in premises has shifted from allowing some people to enter a room to giving permission to specific persons to access a room and recording who entered the room and the time they spent in it. With such need for higher security in mind, we design an access control system for controlling physical access of people to locations or to specific units in these locations. Our study gives emphasis to the organization of physical locations, including nested rooms, and the approach used to assign permission to people to access such locations. We also define some security policies to be used in such model as well as appropriate user interfaces. Finally, we develop two patterns based on our model.

Show moreContinuous changes in the software development community require challenging conventional approaches resulting in techniques that allow for early decisions at the design level. This project is a demonstration of the use of design patterns as a common way to organize objects to make practical design decisions helping to generate flexible, manageable and agile software architectures. Due to the continuity and unpredictability of its requirements, the Biometric Industry is appropriate to illustrate of the use of design patterns and object oriented analysis. First, the conceptual model of an Electronic Fingerprint Service establishes the vocabulary for discussing how a system is constructed. Since good design decisions eventually result in a good design model, this model is used to leverage the object reused when requirements change. The Electronic Biometric Services model demonstrates how by applying design patterns, the system can gain the flexibility and agility required to grow and change according to new requirements.

Show moreSince the publication of the book Design Patterns: Elements of Reusable Object-Oriented Software by the Eric Gamma, Richard Helm, Ralph Johnson, and John Vlissides, there has been substantial interest in design patterns in the software engineering community. One of the goals of design patterns is to capture design expertise developed by some of the most experienced developers so that it can be reused even by less experienced programmers. Like other engineering disciplines, the authors presented their materials using a catalog format. That format can present problems for students and practitioners. As an alternative, we suggest to first replace the text-based description with a web-based description to make it easier to browse through the information. Second, we suggest using more graphical design representations for pattern descriptions to reduce the amount of necessary textual details. Using the process of reverse engineering, we recreate the original design representations of various pattern implementations. Third, we provide additional graphical representations to relate the general pattern description to specific implementations. Finally, we provide a web-based prototype of the new representation and shows how a user can take advantage of such representations.

Show moreIn recent years there has been great interest in implementing object recognition frame work on mobile phones. This has stemmed from the fact the advances in object recognition algorithm and mobile phone capabilities have built a congenial ecosystem. Application developers on mobile platforms are trying to utilize the object recognition technology to build better human computer interfaces. This approach is in the nascent phase and proper application framework is required. In this thesis, we propose a framework to overcome design challenges and provide an evaluation methodology to assess the system performance. We use the emerging Android mobile platform to implement and test the framework. We performed a case study using the proposal and reported the test result. This assessment will help developers make wise decisions about their application design. Furthermore, the Android API developers could use this information to provide better interfaces to the third party developers. The design and evaluation methodology could be extended to other mobile platforms for a wider consumer base.

- Abstract/Description

As computing technology continues to advance, it has become increasingly difficult to find businesses that do not rely, at least in part, upon the collection and analysis of data for the purpose of project management and process improvement. The cost of software tends to increase over time due to its complexity and the cost of employing humans to develop, maintain, and evolve it. To help control the costs, organizations often seek to improve the process by which software systems are developed...
Show moreAs computing technology continues to advance, it has become increasingly difficult to find businesses that do not rely, at least in part, upon the collection and analysis of data for the purpose of project management and process improvement. The cost of software tends to increase over time due to its complexity and the cost of employing humans to develop, maintain, and evolve it. To help control the costs, organizations often seek to improve the process by which software systems are developed and evolved. Improvements can be realized by discovering previously unknown or hidden relationships between the artifacts generated as a result of developing a software system. The objective of the work described in this thesis is to provide a visualization tool that helps managers and engineers better plan for future projects by discovering new knowledge gained by synthesizing and visualizing data mined from software repository records from previous projects.

The proposed application, iVESTA (interactive Visualization and Evaluation System for driven Test dAta), employs a web-based architecture which enables users to upload DTD and immediately visualize the test results and observe phone and network performances with respect to different factors such as dropped call rate, signal quality, vehicle speed, handover and network delays. iVESTA provides practical solutions for mobile phone manufacturers and network service providers to perform comprehensive study on their products from the real-world DTD.

Show moreThe Java Devlopment Environment defines SQLJ as a standard way of embedding the relational database language SQL in the object-oriented programming language Java. Oracle Corporation provides an extension of SQLJ that supports dynamic SQL constructs for the processing of SQL commands that are not completely known at compile time. Unfortunately, these constructs are not sufficient to handle all dynamic situations, so that the programmer has to depend on other SQL embeddings, such as JDBC, in addition to Oracle's SQLJ. In this thesis we implement several extensions to Oracle's SQLJ so that all dynamic situations can be programmed in SQLJ, without resorting to other SQL embeddings. We also add a sub-query based for loop facility, similar to the one provided in Oracle's database programming language PL/SQL, as an improvement over the iterator constructs that SQLJ provides. This thesis discusses the design, development and implementation of these SQLJ extensions, and provided applications that show the utility of these extensions in terms of clarity and power.

Real-time systems are systems where time is considered a system resource that needs to be managed. Time is usually represented in these systems as a deadline to complete a task. Unfortunately, by adding timing to even simple algorithms, it complicates them greatly. Real-time systems are by nature difficult and complex to understand.

Show moreReal-time systems are systems where time is considered a system resource that needs to be managed. Time is usually represented in these systems as a deadline to complete a task. Unfortunately, by adding timing to even simple algorithms, it complicates them greatly. Real-time systems are by nature difficult and complex to understand. Object-oriented methodologies have attributes that allow real-time systems to be designed and implemented with less error and some control over the resultant complexity. With object-oriented design, the system is modeled in the environment that it will be used in. Objects themselves, are partitions of the system, into logical, understandable units. In this dissertation, we start by surveying the current real-time object-oriented design methodologies. By comparing these methodologies and developing a set of criteria for evaluating them, we discover that certain aspects of these methodologies still need some work. The most important aspects of the methodologies are understanding the effects of deadlines on statechart behavioral models and understanding the effects of deadlines when object models are inherited or undergo aggregation. The effects of deadlines on statecharts are then explored in detail. There are two basic ways that deadlines are added to statecharts. The first, and most popular, is adding timing as a condition on a state transition. The second is adding a count down timer to a state and forcing a transition if the timer reaches zero. We show that these are equivalent and can be used interchangeably to simplify designs. Next, the effects of deadlines on behavior models when the corresponding object models undergo inheritance or aggregation are studied. We will first analyze the effects on the behavior model when object inheritance is encountered. We found eight ways that the behavior model can be modified and still maintain the properties of inheritance. Finally, deadlines are added and the analysis is repeated.
