Construction of Pipelined Strategic Connected Dominating Set for Mobile Ad Hoc Networks

Efficient routing between nodes is the most important challenge in a Mobile Ad Hoc Network (MANET). A Connected Dominating Set (CDS) acts as a virtual backbone for routing in a MANET. Hence, the construction of CDS based on the need and its application plays a vital role in the applications of MANET. The PipeLined Strategic CDS (PLS-CDS) is constructed based on strategy, dynamic diameter and transmission range. The strategy used for selecting the starting node is, any source node in the network, which has its entire destination within a virtual pipelined coverage, instead of the node with maximum connectivity. The other nodes are then selected based on density and velocity. The proposed CDS also utilizes the energy of the nodes in the network in an optimized manner. Simulation results showed that the proposed algorithm is better in terms of size of the CDS and average hop per path length

ISPS in system design

This dissertation demonstrates the utility of the Instruction Set Processor Specification (ISPS) in a design environment. Although ISPS supports a wide range of applications in the areas of architecture evaluation and certification, design automation, software generation and fault simulation, the .emphasis in this dissertation is focused on using it in design verification and performance evaluation of a 16-bit processor, AF85. The utility of ISPS to support fault simulation at the functional level is also illustrated by several examples applied on AF85

An approach for selecting a language for computer hardware description and simulation

This paper corrects an apparent deficiency in the published information concerning Hardware Description Languages (HDLs) by introducing and discussing an approach for selecting an HDL for use in a design project. Although three classes of HDLs are discussed in this paper, High-Level Languages (HLLs), General Purpose Simulation Languages (GPSLs) and Computer Hardware Description Languages (CHDLs), the CHDL class has been most heavily emphasized. These have been emphasized because they have been found to be the most suitable for use as a digital design tool. The emphasis is realized by including a chapter reviewing CHDL fundamentals, by presenting several CHDL examples and by aiming the HDL selection approach toward choosing a CHDL. HLLs and GPSLs are appropriate selections for some digital design environments. Therefore these classes of HDL have also been discussed in this paper

Satellite orbit computation methods

Mathematical and algorithmical techniques for solution of problems in satellite dynamics were developed, along with solutions to satellite orbit motion. Dynamical analysis of shuttle on-orbit operations were conducted. Computer software routines for use in shuttle mission planning were developed and analyzed, while mathematical models of atmospheric density were formulated

REGTRAN and MICRO, the implementation of two digital system simulators

REGTRAN (REGister TRANsfer), a hardware description language and SYSSIM (SYStems SIMulation), a simulator for the system described by REGTRAN were originally developed by Edward Pett, Jr [33] at the University of Texas at Austin. These two programs are successfully used to simulate many digital systems of complex nature. It is the primary purpose of this paper to describe the implementation of these two programs for KRONOS at Oregon State University. In this process, various problems, due to the differences in the operating systems, were faced. These problems are discussed in detail and the changes that were made are included. REGTRAN and SYSSIM are not capable of simulating micro-instructions or a microprocessor. For this reason, another simulator MICRO is developed. Detailed description of MICRO and its use as a general purpose simulator as well as a microprogram simulator are given in detail. As an example, partial emulation of DEC PDP-8 is shown. Suggestions for the improvement of MICRO, REGTRAN and SYSSIM are mentioned

On Sustainable and Efficient Design of Ground-Source Heat Pump Systems

This paper is mainly aimed at stressing some fundamental features of the GSHP design and is based on a broad research we are performing at the University of Pisa. In particular, we focus the discussion on an environmentally sustainable approach, based on performance optimization during the entire operational life. The proposed methodology aims at investigating design and management strategies to find the optimal level of exploitation of the ground source and refer to other technical means to cover the remaining energy requirements and modulate the power peaks. The method is holistic, considering the system as a whole, rather than focusing only on some components, usually considered as the most important ones. Each subsystem is modeled and coupled to the others in a full set of equations, which is used within an optimization routine to reproduce the operative performances of the overall GSHP system. As a matter of fact, the recommended methodology is a 4-in-1 activity, including sizing of components, lifecycle performance evaluation, optimization process, and feasibility analysis. The paper reviews also some previous works concerning possible applications of the proposed methodology. In conclusion, we describe undergoing research activities and objectives of future works
