In a typical method of database design, ER diagrams are used to represent the conceptual schema of the database. Use-cases are now widely used to capture requirements in designing the basic architecture of an object-oriented system. Use-cases are highly effective in designing forms required for data insertion, retrieval, update, and...
This report deals with environmental strategies. Such strategies involve comprehensive and broad outlooks. In contrast, environmental tactics involve more limited concerns which can be usually addressed in a disciplinary or multi-disciplinary manner. The development of strategies necessitates interdisciplinary and transdisciplinary outlooks. Such outlooks are extremely difficult to achieve because different...
"The purpose of this report is to present methods and procedures for monitoring estuarine benthic systems. Emphasis is given to those features of benthic systems of significant ecological importance. While the experience of the authors has been within estuarine environments, the material contained herein is relevant to a wide range...
Despite the considerable advances of deposition technologies, it remains a significant challenge to form conformal deposition on surface of nanoporous carbons. Here, we introduce a new ambient hydrolysis deposition method that employs and controls pre-adsorbed water vapor on nanoporous carbons to define the deposition of TiO₂. We converted the deposited...

We, for the first time, demonstrate that orthorhombic V₂O₅ can exhibit superior electrochemical performance in sodium ion batteries when uniformly coated inside nanoporous carbon. The encapsulated V₂O₅ shows a specific capacity as high as 276 mAh/g, while the whole nanocomposite exhibits a capacity of 170 mAh/g. The V₂O₅/C composite was...

Na-ion batteries are emerging as one of the most promising energy storage technologies, particularly for grid-level applications. Among anode candidate materials, hard carbon is very attractive due to its high capacity and low cost. However, hard carbon anodes often suffer a low first-cycle Coulombic efficiency and fast capacity fading. In...

In this project we examine the features of object oriented programming languages that make them most likely languages of choice for implementing simulations. Three simulations of a bank, hospital, and livestock farm scenarios were implemented in the language C++ in order to demonstrate how Object-Oriented languages are used in constructing...
Data structures are essential for any programming task. Most of modem programming languages have a library of reusable data structures. In this project, Smalltalk-like collection classes have been implemented as a Java package. This package, collections, contains several useful data structures such as binary tree, B-Tree, bag, list, hash table...
This dissertation proposes the use of advanced time-varying approaches for modeling the dynamics of the multipath channel in wireless communication networks. These advanced time-varying approaches include linear Kalman innovation models in observable block companion form, and neural network-based models. The e˙ectiveness of these type of models is evaluated through three...
