An Evolutionary Multi-Objective Crowding Algorithm (Emoca): Benchmark Test Function Results, Ramesh Rajagopalan, Chilukuri K. Mohan, Kishan G. Mehrotra, Pramod K. Varshney Dec 2005

An Evolutionary Multi-Objective Crowding Algorithm (Emoca): Benchmark Test Function Results, Ramesh Rajagopalan, Chilukuri K. Mohan, Kishan G. Mehrotra, Pramod K. Varshney

Electrical Engineering and Computer Science - All Scholarship

A new evolutionary multi-objective crowding algorithm (EMOCA) is evaluated using nine benchmark multiobjective optimization problems, and shown to produce non-dominated solutions with significant diversity, outperforming state-of-the-art multi-objective evolutionary algorithms viz., Non-dominated Sorting Genetic Algorithm – II (NSGA-II), Strength Pareto Evolutionary algorithm II (SPEA-II) and Pareto Archived Evolution Strategy (PAES) on most of the test problems. The key new approach in EMOCA is to use a diversity-emphasizing probabilistic approach in determining whether an offspring individual is considered in the replacement selection phase, along with the use of a non-domination ranking scheme. This approach appears to provide a useful compromise between the …


Design Of A Prototype Model Aircraft Utilizing Propulsive Airfoil Technology, Richard L. Pepe May 2005

Design Of A Prototype Model Aircraft Utilizing Propulsive Airfoil Technology, Richard L. Pepe

Honors Capstone Projects - All

Researchers have considered the concept of a simple, compact aircraft for personal use for many years. To date, no effort has led to the development of a practical and affordable vehicle. The Computational Fluid Dynamics (CFD) Lab atSyracuseUniversity, however, has been researching a distributed propulsion technique, called propulsive airfoil technology, that has significant promise to meet the requirements for personal ownership of a small, hybrid road and air vehicle.

The propulsive airfoil concept is rooted in HVAC technology, utilizing a cross-flow fan (CFF) embedded into the trailing edge of a thick airfoil section, drawing in air from the top surface …


Using A Pda To Control Home Appliances, Atif Albraiki May 2005

Using A Pda To Control Home Appliances, Atif Albraiki

Honors Capstone Projects - All

The Personal Digital Assistant (PDA) is a handheld device that gives users different organizational capabilities. Over the years, the functionality of PDAs has expanded tremendously to include internet connectivity and different computer applications. The purpose of my honors thesis, combined with my engineering senior design project, was to include a new functionality to the PDA and use it to control different home appliances. The goal of the project was to develop a PDA program that will communicate with a PC program, and have the PC program communicate with a microcontroller to control home appliances. My part of the project was …


Studies On Novel Semiconductor Detectors And Front-End Electronics For Heavy Flavor Decay Studies, Gustavo Kertzscher May 2005

Studies On Novel Semiconductor Detectors And Front-End Electronics For Heavy Flavor Decay Studies, Gustavo Kertzscher

Honors Capstone Projects - All

I have studied novel semiconductor detectors designed to provide precise space point information of the trajectory of charged subatomic particles produced in high energy physics (HEP) collisions. The technological thrust aims toward maintaining good performance of these detectors in a hard radiation environment for an extended period of time. My studies approached two different types of silicon devices: a whole wafer comprised of test structures and pixel devices designed for the inner vertex detector of the BTeV experiment, and small test structures of a novel type of quasi-3D detectors developed in the context of the CERN RD50 collaboration. This collaboration …


Modeling Interface Failure In Fiber-Composites, Andrew J. Craig May 2005

Modeling Interface Failure In Fiber-Composites, Andrew J. Craig

Honors Capstone Projects - All

Interface failure has been studied in depth for more than the past twenty years due to its significant impact on the application of composite materials. The objective of this work is to investigate the role of the interface in the mechanical response of fiber-matrix composite materials subjected to an applied load. To do this, a single composite cylinder consisting of a rigid core, the fiber, and an elastic annulus, the matrix, with an interface of vanishing thickness separating them, is considered as the first step in what will later be representative of a composite material. Three non-linear, Needleman-type, force-separation relations …


Analyst-Focused Arabic Information Retrieval, Robert N. Oddy, Ann R. Diekema, Jean Hannouche, Elizabeth Liddy, Grant Ingersoll Jan 2005

Analyst-Focused Arabic Information Retrieval, Robert N. Oddy, Ann R. Diekema, Jean Hannouche, Elizabeth Liddy, Grant Ingersoll

School of Information Studies - Faculty Scholarship

An English-Arabic Cross-Language Information Retrieval Environment was created in which the analyst can query an Arabic database in English and retrieve a set of relevant Arabic documents. The retrieved Arabic documents are automatically translated into English to facilitate readability by the English-only analyst. Proper names of people, places, and organizations are extracted from the retrieved documents and transliterated from Arabic into English. They are presented to the analyst and serve to provide a brief summarization of the retrieved document search query in English. Cross-Language Information Retrieval (CLIR), itself a desideratum in the ARDA workshop, is a special case of Information …


A Beacon-Less Location Discovery Scheme For Wireless Sensor Networks, Lei Feng, Wenliang Du, Peng Ning Jan 2005

A Beacon-Less Location Discovery Scheme For Wireless Sensor Networks, Lei Feng, Wenliang Du, Peng Ning

Electrical Engineering and Computer Science - All Scholarship

In wireless sensor networks (WSNs), sensor location plays a critical role in many applications. Having a GPS receiver on every sensor node is costly. In the past, a number of location discovery schemes have been proposed. Most of these schemes share a common feature: they use some special nodes, called beacon nodes, which are assumed to know their own locations (e.g., through GPS receivers or manual configuration). Other sensors discover their locations based on the information provided by these beacon nodes. In this paper, we show that efficient location discovery can be achieved in sensor networks without using beacons. We …


Enhancing Erp System’S Functionality With Discrete Event Simulation, Young Moon, Dinar Phatak Jan 2005

Enhancing Erp System’S Functionality With Discrete Event Simulation, Young Moon, Dinar Phatak

Mechanical and Aerospace Engineering - All Scholarship

Purpose – To develop a methodology to augment enterprise resource planning (ERP) systems with the discrete event simulation’s inherent ability to handle the uncertainties.

Design/methodology/approach – The ERP system still contains and uses the material requirements planning (MRP) logic as its central planning function. As a result, the ERP system inherits a number of shortcomings associated with the MRP system, including unrealistic lead-time determination. The developed methodology employs bi-directional feedback between the non-stochastic ERP system and the discrete event simulation model until a set of converged lead times is determined.

Findings – An example of determining realistic production lead-time data …
