SimSite R.B. Gilbert Civil Engineering Geotechnical Engineering Engineering Geology SimSite is a computer simulation to simulate a site investigation to evaluate the need for remediation. It can be used to educate future practitioners in performing and interpreting site investigations. The Authors have identified four specific objectives of the simulation experience: the user will (1) develop a model for the site and be able to compare that model with the actual site conditions; (2) conduct the investigation with limited resources including money and time; (3) deal with uncertainty and variability just as in real investigations; and (4) be exposed to some of the common technology used in site investigations.

An experimental study of Roman dropshaft hydraulics H. CHANSON, MIAHR, Civil Engineering Hydraulic Engineering and Infrastructure Hydraulics, Hydrology In Roman aqueducts, series of vertical dropshafts were used to dissipate the kinetic energy of the flow: i.e., the dropshaft cascades. A re-analysis of Roman dropshaft hydraulics is conducted with physical model tests. Three basic flow patterns are observed. The results demonstrate that the vertical dropshafts could be very efficient energy dissipators and re-oxygenation structures, under appropriate flowconditions. The optimum operation ofRoman dropshaft is discussed and an analytical model is developed to predict these conditions. Further the performances of aqueduct dropshafts are compared with modern dropshaft designs, and the operation of dropshaft cascades is discussed. Additional material is available upon request.

TEACHING HYDRAULIC DESIGN IN AN AUSTRALIAN UNDERGRADUATE CIVIL ENGINEERING CURRICULUM Dr Hubert CHANSON Engineering Education Curriculum Development and Implementation Curricula Design, Combined Research-Curriculum Development Since the early European settlements, Australia's economy has been highly dependent upon its water supply, although limited because of the dry climate. Today, the Australian continent is equipped with a large number of hydraulic structures per capita, and hydraulic engineering expertise is critical to future developments. In the universities, the civil engineering and environmental engineering undergraduate courses include a significant number of fluid mechanics and hydraulics subjects, including an introduction to hydraulic design. At the University of Queensland, the teaching of hydraulic design is focused on the sound application of the basic principles of fluid mechanics. Basic applications include the hydraulic design of spillways and culverts. Each type of design is supported by a series of lectures and a case study involving homework, a field visit, and a series of tutorials. Practical classes (laboratory and field visit) are an indispensable complement of the lectures. The subject assessment is based upon a combination of homework, practicals, and end-of-semester examination grades.

A Construction Education Searchable Database for MBE and WBE Construction Firms Christine Piper Engineering Education Continuing Education Developing Continuing Education Programs in Engineering This paper intends to provide information regarding a construction education searchable database for MBE and WBE Construction Firms. A survey by the Carolinas Associated General Contractors (AGC) of design and construction professionals in the state of South Carolina identified a need for a continuing education course in construction management processes for individuals working for Minority Business Enterprises (MBE) and Women-owned Business Enterprises (WBE) construction firms. The original objective of the research was to develop continuing education course modules addressing basic project management processes that MBE and WBE construction firms need to know in order to successfully manage a federally funded highway construction project. As the research progressed, it was determined that there was an overlap between the proposed course modules and existing educational training opportunities. This paper describes the development of a CD-ROM searchable database of all training modules, seminars and courses offered in the state of South Carolina or available from other states via home study applications for MBE and WBE construction firms.

A New Paradigm For Assessing Teaching Effectiveness Amir W. Al-Khafaji Engineering Education Student/Faculty Development Developing Course Preparation and Teaching Skills The main objective of this article is to raise fundamental issues for educators by offering a broader understanding of teaching effectiveness and propose suitable measures. Often, teaching performance is narrowly measured using student course evaluations. Such a limited approach fails to distinguish lenient instructors from demanding instructors and those who are on the cutting edge of technology from those who are unwilling to adapt or accept change. The conventional approach is not adequate to educate students, to advance the state of knowledge, and to enhance the stature of the professorate so that higher education systems continue to flourish (Al-Khafaji, et al, 1998). The proposed approach provides a flexible model that integrates several factors in the development of a comprehensive teaching assessment program.

A Study of Management Practices in Small-Volume Home Building Companies D. Mark Hutchings Jay P. Christofferson Civil Engineering Construction Engineering and Management Construction Management, Construction Safety The majority of home building companies in the United States produce fewer than ten homes per year. To better understand the management practices of these builders, surveys were sent to 559 randomly-selected small-volume home builders nationwide. This research report summarizes the responses. The literature review pinpointed a number of management practices implemented by successful small businesses. Although some of the management principles described were followed by the respondents, there were many practices which were neglected. Some of the major shortcomings identified included a lack of business planning, a lack of written documentation, and a neglect of employee training.

An Application of fuzzy Modeling in Construction Engineering Mag Malek Civil Engineering Construction Engineering and Management Construction Management, Construction Safety The focus of this paper is the development of a model to measure the constructability of concrete construction systems. Fuzzy Set Theory (FST) is used to quantify the importance of the primary constructability characteristics: quality, safety, cost, and scheduling. Linguistic rules are also developed to provide a verbal measure of project constructability. The developed model is a constructability assessment tool that is generic enough to allow the company to encompass the particular criteria of the project at hand and to select the construction system best suited for project execution.

An Evaluation of the Good Cents Program in College Station, Texas Lee A. Ellingson Paul K. Woods Civil Engineering Architectural and Building Engineering Intelligent Buildings, Sustainable Buildings The Good Cents Program is designed to encourage builders to build more energy-efficient homes. One difficulty with evaluating this type of program is that energy use not related to outdoor air temperature introduces a large amount of unexplained variability into total energy use. This study uses a statistical method that separates energy related to outdoor temperature from energy not related to outdoor temperature. Three-parameter models have proven to be very useful in modeling residential energy use. This study uses parameter estimates of three-parameter models to compare a treatment group of Good Cents houses to a control group of non-Good Cents houses. Parameters used are cooling slope, heating slope, and Normalized Annual Consumption (NAC).

Building Integrated Photovoltaics: An Analysis of the Benefits of Photovoltaic Coated Glazing in Commercial Buildings Keith E. Sylvester J. H. Haberl Civil Engineering Architectural and Building Engineering Intelligent Buildings, Sustainable Buildings Energy efficient glazing is necessary to reduce heat gains or losses that contribute to the highenergy use of buildings. However, high-rise commercial buildings that use energy efficient glazing are still consumptive. To reduce their energy use further, recent studies have integrated photovoltaic glazed window systems into the building shell. To understand the relationship between photovoltaic windows, energy use and human satisfaction, this paper presents a study of the effects of photovoltaic glazed windows on the energy use of large commercial buildings and includes an assessment of the overall human satisfaction of the workers within photovoltaic glazed office spaces. Specifically, this study targeted high-rise commercial buildings and their occupants in urban centers of the four census regions of the US - West, Northeast, South, and Midwest. A prototypical building was used to develop the base case simulations for the DOE-2 energy simulation program and the PV F-Chart photovoltaic analysis program. By substituting the appropriate variables in the base case simulation for each site, the building was simulated to evaluate the impact of the PV glazing on the building?eat loss/gain as well as the amount of electricity that could be expected from the PV.

Characterizing Green Residential Construction for Green Builder Programs and Construction Education Audrey K. Tinker Richard Burt Civil Engineering Architectural and Building Engineering Intelligent Buildings, Sustainable Buildings The importance of green construction techniques and products is impacting the residential construction sector as educated clients are beginning to demand environmentally friendly homes and green builders are finding success constructing and selling green homes. In response, the popularity and number of residential green building programs is increasing around the country, as is an emphasis on green building at universities. However, there is still much debate concerning exactly what a green residence is. Existing green building programs have both different categories of green features and different specific measures that are used in their checklists to certify green homes. Many features could fit into several categories, thus making a consensus on exact placement difficult. This paper discusses the similarities and differences in green residential rating systems between eight green building programs throughout the United States.

Communication of Project Information Between Builder and Designer: An Analysis of Computer Mediated Communication Techniques Benjamin Wesley Sass Kenneth C. Williamson Civil Engineering Construction Engineering and Management Construction Management, Construction Safety The continual search for better ways to communicate project information has been a recurring challenge in the built enterprise. The purpose of this proposed study is to investigate the affect of computer mediated communication between the designer and builder on the amount of time and money spent in the design and construction of residential projects. Particularly, the differences between a World Wide Web interface and the traditional "hard-copy" system for the review and submittal of construction documents will be examined. An extranet will be set up for MM Design in Bryan, Texas that will allow builders to review drawings in progress as well as submit comments relating to changes in the documents. The number of submittals as well as the amount of time spent on construction document development will be measured and compared between the two methods for builder/designer interaction.

Comparison of Construction Firms Based on Fuzzy Sets Amaury A. Caballero Jack Dye Civil Engineering Construction Engineering and Management Construction Management, Construction Safety The paper builds upon and extends a previous work of the authors. It presents a methodology allowing individuals or organizations to compare the capacity of construction firms using a fuzzy logic expert system model. The paper briefly discusses the concept of fuzzy logic and the task of choosing an appropriate family of parametric membership functions by which to define capacity. The extended methodology is an alternative to a previously developed multiple attribute analytical hierarchical procedure that was developed to enable general contractors to rate the capacity of minority and small/disadvantaged business subcontractors. The model provides a means by which general contractors, private owners, or public agencies can rank competing construction organizations on matters other than the bid price for the work.

Computer Integrated Construction for Small And Medium Contractors Hazem Elzarka Civil Engineering Construction Engineering and Management Construction Management, Construction Safety Computer integrated construction (CIC) systems have a tremendous potential to improve the productivity of the construction industry. CIC systems can automate such business functions as design, estimating, scheduling, value engineering, cost control, materials management, site analysis and facility management. Until recently, only large construction companies could afford the expensive in-house development of CIC systems. Recent advancements in software and hardware technologies however, have made CIC systems within the reach of many small and medium contractors. Off-the-shelf stand-alone packages can now be integrated to develop CIC systems. The paper discusses a cost-effective approach for developing CIC systems by integrating stand-alone CAD, spreadsheet, database and scheduling software packages using Visual Basic for Applications (VBA). The paper ends by presenting a three dimensional CIC prototype system that integrates off-the-shelf packages. The prototype was developed for a concrete subcontractor to demonstrate the potential of CIC to improve the constructability analysis and the construction management process of concrete projects. The prototype is capable of generating three-dimensional intelligent construction objects, generating quantity takeoff and integrating with schedule.

Computer-Assisted Tutorials for Structures Instruction Anoop Sattineni Roger Killingsworth Engineering Education Curriculum Development and Implementation Assessment, Evaluation and Modernization of Existing Curricula In Fall semester 2000 Auburn University made the transition from quarters to semesters. University administration mandated a limit of 120 semester units for all programs. To meet this limit the construction management faculty had to delete all repetition from the construction management undergraduate curriculum including a review of physics principles at the beginning of the structures sequence. As a replacement, computer-assisted tutorials were developed for students to use outside the classroom. The tutorials covered basic topics using interactive questions, pictures, diagrams and video clips. The students' grasp of the principles was measured by means of a quiz at the end of each unit. The quizzes comprised 5 percent of the term grade to encourage student participation. A questionnaire, tutorial generated data and a comparison of quarter grades with semester grades were used to provide a preliminary evaluation of the tutorials. The preliminary evaluation suggested that while some improvements were needed, the tutorials were successful in providing the needed review. The process of creating these tutorials and the results of the survey conducted are detailed in this manuscript.

Devising a Model for Measuring the Effectiveness Level of Construction Organizations Tony Kiani Civil Engineering Construction Engineering and Management Construction Management, Construction Safety, Quality Control This paper presents the process for devising a model to measure the effectiveness of construction organizations. The basic principles of Total Quality Management philosophy and the Constituency theory have been synthesized to devise such a model. The proposed model provides the owners of the construction projects a tool to predict the overall quality of their projects. This research, after analyzing an abundance of variables, identifies two variables as the most significant ones. These two independent variables are related to the capability of the prime contractor being on schedule and the ability to comply with the specifications. The proposed model is a customer driven model; the independent variables being the level of satisfaction of the external and internal customers.

Effectiveness of the Specification, Low-Bid Construction Delivery System Dean Kashiwagi Rudy Erdmann Civil Engineering Construction Engineering and Management Construction Management, Construction Safety, Quality In the last decade, the construction industry performance has been scrutinized. A diminishing supply of trained craftspeople, litigation, nonperformance (not on time, on budget, or meeting quality expectations) has led to different approaches to correct the problems. One solution moves away from the conventional design, bid, build process, which awards to the low-bidder to design-build, construction management at risk, indefinite quantity, indefinite delivery (IDIQ) contracts that include Job Order Contracting (JOC) and time and materials contracts. Other movements involve more inspection and project management. A third major movement is performance based contracting. The objective of this research paper is to identify the source of current construction industrys nonperformance. A methodology developed at Arizona State University, uses the Information Measurement Theory (IMT), coupled with survey results from over 300 contractors from Arizona, California, New York, Florida, Michigan, and Texas, to identify the source of nonperformance.

Engineering Evaluation Criteria 2000 - A Critical Review Centered on Construction Education Bolivar A. Senior Engineering Education Curriculum Development and Implementation Curriculum Standards, Meeting ABET Requirements The Accreditation Board for Engineering and Technology, ABET, has developed a new set of evaluation criteria that departs from traditional standards by its compactness, the absence of specific credit hour requirements, its emphasis on setting goals and measuring outcomes, and the discretion given to programs to prove that accreditation requirements have been met. This article reviews and critiques the background and provisions of this new standard, emphasizing its similarities and differences with the new accreditation standard of the American Council for Construction Education, ACCE. This latter document has been substantially modified from the previous versions, and also emphasizes outcome assessment, although with a more detailed approach than its ABET counterpart.

Enhancing Value Engineering by Integrating CAD and Estimating Software Hazem Elzarka Robert Dorsey Civil Engineering Construction Engineering and Management Construction Management, Construction Safety, Quality Value engineering (VE) is a proven management tool to ensure the best functional balance between the cost, reliability, and performance of construction projects. VE is one of several preconstruction activities that are performed to enable clients to make intelligent and informed decisions about constructing their facilities. In a VE study, initial and follow on costs of various design alternatives, should be weighed against other important non-economic criteria such as aesthetics. The best alternative that achieves owner?equirements with the least life-cycle cost should be selected. Often, however, due to time restraints, a comprehensive study of the impact of various alternatives on cost and aesthetics is not performed.

Mead Civil Engineering Architectural and Building Engineering Intelligent Buildings, Sustainable Building Given increased global concerns with environmental degradation, declining natural species, and global warming, there has been an accelerated movement toward increasing the sustainability of the built environment. In the United States this movement is called the Green Building movement. Green Buildings are buildings that are designed, constructed, operated, and demolished in an environmentally and energy efficient manner. Green Building concepts include energy efficiency and conservation, indoor environmental quality, resource and material efficiency, and improved long term durability. This paper will describe the current state of Green Building in the United States through an investigation of Green Building design principles and four case studies of recently completed commercial buildings. Additionally, the paper will describe the LEED system for measuring building sustainability.

Implementing Quality Control Topics Into The Building Construction Curriculum James L. Jenkins Civil Engineering Construction Engineering and Management Construction Management, Construction Safety, Quality Quality control is essential to the construction industry. A large number of contractors use quality control methods to improve productivity, eliminate the cost of rework, and increase customer satisfaction. While college educators do not dispute these facts, quality control is sometimes overlooked or simply not given a high priority in terms of curriculum planning. The following paper demonstrates the need for quality control to be taught in the classroom and outlines a proposal for implementation of such an addition.

Instructional Design and Use of Interactive Online Construction Exercises Richard C. Ryan Srinath P. Kasturi Engineering Education Instructional Design Technologies/Media in Instructional Design for Engineering The availability of online education is increasing based on current review of announcements and advertisements for continuing education and university offerings. Today we are at a point of growth in online education where we should be seeking to optimize Internet capabilities to deliver more engaging educational experiences. Available web development and database tools are providing greater opportunity to do this. However, online efforts must compensate for the missing interactive component in order to be successful. An automated self-paced interactive format combining animation, video and audio has great potential to overcome or minimize this perception and capture the imagination of the student reinforcing necessary concepts just as well as a "good" Instructor.

Teaching Business Survival Skills to Construction Managers John E. Schaufelberger Civil Engineering Construction Engineering and Management Construction Management, Construction Safety Construction is a risky business, and construction managers often lack the necessary business management skills to be successful. Recent research indicates that ineffective business planning and management often are the primary causes of business failures among construction firms. Interviews with successful construction firms reinforce the importance of good business planning and financial management skills. Both skills need emphasis in construction management curriculums. Effective business planning involves assessing the firm's status, internal strengths and weaknesses, and external opportunities and threats, and selecting strategies and action plans to achieve organizational goals and objectives.

Technological Advances in Geothermal Energy Applications in Construction M.Malek Electrical Engineering Energy/Power Systems New and Renewable Energy Resources Geothermal Energy is heat (thermal) derived from the earth (geo). It is the thermal energy contained in the rock and fluid (that fills the fractures and pores within the rock) in the earth's crust. The current production of geothermal energy is placed third among renewables, following hydroelectricity and biomass, and ahead of solar and wind. Despite these impressive statistics, the current level of geothermal use pales in comparison to its potential. The key to wider geothermal use, is greater public awareness and technical support. Geothermal Energy applications in construction are vital. Ground-source heat pumps use the earth or groundwater as a heat source in winter and a heat sink in summer. Geothermal energy is a domestic energy resource with cost, reliability and environmental advantages over conventional energy sources. Geothermal energy contributes both to energy supply, with electrical power generation and direct-heat uses, and to reduced energy demand, with savings in electricity and natural gas through the use of geothermal heat pumps. The contribution of this paper is that; it is a survey of the recent advances in geothermal energy and it provides an analysis identifying both the advantages and shortcomings of this rapidly developing technology.

Building Surveillance Equipment Tiberius Parcalabu Vlad Panait Mihai Mircea Electrical Engineering Computer Computer Networking, LAN, WAN, Mobile, Client Server Computing After the September 11th attack in New York City, people started considering whether there are ways to help and inform people in case of disasters, such that quick intervention at the affected area is possible with maximum effects. The proposed system is intended to operate for structures visited by a large number of people. We developed a low-priced wireless distributed system that collects data from different sensors and informs both the people inside (they are directed on the shortest safest exit paths) and the outside parties (police or firemen service that can use the information for better rescue operations). In case of a catastrophe (fire, earthquake, terrorist attack, etc.), even if a part of the proposed system is destroyed, the rest uses existing information to guide rescue operations. Moreover, lack of information (possibly together with other information like ?temperature was very high before communication was interrupted?) may be interpreted as ?seriously damaged area?, leading to calculating safe-exit paths around it. The system consists of a distributed LAPE (Local Acquisition and Processing Element) network that has as main function the monitoring of the parameters in a large building. The data collected by one of the LAPEs is shared in the whole system via Bluetooth devices. Each individual LAPE calculates the best exit path based on the status of the building. The system also communicates the state of the whole building to the outside parties for surveillance tasks. The intervention teams can create good and realistic emergency plans based on the information collected by the system. They can also direct people to a new evacuation mean available (an intervention helicopter, for example). In case of emergency, it is feasible to envision that human experts override the directions by new ones, in case they have other information not available to the system. The system is designed as an Open Interface, implying it easily supports the addition of sensors and functionality to the structure.

CarTooth Project - Car Payment System Michal Rein Michal Kowalski Bartosz Nowierski Electrical Engineering Computer Computer Networking, LAN, WAN, Mobile, Client Server Computing Paying for parking, gasoline or toll highways is always a waste of time and an inconvenient procedure. To solve this problem we introduce Car Payment System (CPS) which offers: - full automation of paying for parking and other car-related payments, - charging for actual time of parking in city parking zones, - car monitoring. Our solution will change life of every driver. They will not waste their time anymore searching for a parking meter because the parking meter will find them. They will not have to pay a parking ticket ever again since the devices of our system will pay parking fees for them automatically, not absorbing their attention. When they come back to their car it will be still there because our parking meter will keep thieves away. Moreover, drivers can easily pay, for example, toll road fees or gas charges without stepping out of a car. While designing we intended to create a system which would be practical and fully economically justified. We put emphasis on ensuring transaction security and keeping the price of end-user devices low. Car Payment System ideally fits into the idea of Personal Area Network. Every car has its own CarTooth with Bluetooth onboard. It exchanges information and makes transactions with stationary devices of our system using Bluetooth technology. These devices are scattered all over the city and create a set of wireless networks. In this report we describe Car Payment System from many points of view. The most important part ? CarTooth is discussed thoroughly with regard to hardware, software and related algorithms. We present other modules focusing on their functionality and explain how they cooperate with CarTooth. The report gives the detailed description of solutions to the problems concerning wireless safe transfer of money and recognition of the state of a car. We also cover requirements of users and marketing issues connected with putting CPS into practice.

Mobile Sleep Laboratory:Body Monitoring System with EEG Sensors Peter Lacko Peter Blstak Matus Horvath Electrical Engineering Computer Computer Networking, LAN, WAN, Mobile, Client Server Computing In this report, we describe the mobile Body Monitoring System that can be used for monitoring patients in their natural environment. Its design is focused on creating a universal device suitable for monitoring various functions of human body. This was achieved by supporting loadable communication and device drivers, allowing the monitor unit to connect to almost any sensor using either wired or wireless technologies. To control the behaviour of the Body Monitoring System we developed a special language called Policy Markup Language (PML), which is used to represent policies. Policies describe monitor unit?s response to events reported by sensors. PML is powerful enough to allow describing most situations that can occur when monitoring a person. As a prototype, we developed a mobile sleep laboratory consisting of a monitor unit and two sensors: an electroencephalograph (EEG) and a thermometer. Both sensors connect to the monitor unit using a Bluetooth wireless connection, utilising a custom Message eXchange Protocol (MXP). We have created device drivers for both devices, the EEG one being able to analyse which sleep stage the monitored person is in. Like every other system that stores sensitive personal data the Body Monitoring System has to be reliable and secure. We designed a secure way how to store and transfer measured medical data using symmetric cryptographic algorithms. To ensure our prototype works properly, we have employed extensive validation and testing procedures. There are many possible use cases for the Body Monitoring System. The domain of the system are medical applications like permanent monitoring of a cardiac, taking care of elder or disabled people, preventing the Sudden Infant Death syndrome, or controlling a network of subdermal sensors that would measure hormone levels. But the system can be used in more spheres of human activity, e.g. monitoring people working in dangerous environments.

Rigorous Treatment of Electrical Conduction and Thermo-Electric Effects in Semiconductors (collection of flash simulation) Phuong Nguyen Daryoosh Vashaee Tara Madhyastha Ali Shakouri Electrical Engineering Electronics Quantum Electronics Theory One can treat electrical and thermal conduction and the thermoelectric effects in semiconductors in a unified approach using the concept of "differential conductivity"(i.e. conductivity of electrons with a given energy inside the solid). The traditional derivation based on the Boltzmann transport equation and relaxation time approximation is calculation intensive and it is not appropriate for undergraduate education. It is also difficult to gain insight about the underlying physics. Here we created a user-friendly interface for the Boltzmann transport equation. The key functions such as density-of-states, Fermi-Dirac distribution function and differential conductivity are plotted versus electron energy. Electron mobility, electrical conductivity and Seebeck coefficient are accurately calculated based on the transport model described below. One can change the material properties (such as electron effective mass and mean-free-time between collisions) or the ambient temperature and see how these graphs are modified and what is the effect in the overall conductivity and Seebeck coefficient.

MIXED-SIGNAL MULTI-LEVEL CIRCUIT SIMULATION: AN IMPLICIT MIXED-MODE Xing Zhou Electrical Engineering Devices, Materials and Fabrication VLSI and Nanotechnology A unified and consistent approach to multi-level simulation of mixed-signal VLSI circuits is presented. It isbased on the subcircuit expansion approach, in which digital gates have a dual-representation at the logic andcircuit levels. Dynamic circuit partitioning and mode switching are achieved with the single-engine simulator.A dynamic-delay model is described for gate-level timing simulation, which includes the effects of nonlinear capacitiveloading, input transition time, and multiple-input triggering. It is shown that the approach provides near circuit-levelaccuracy with gate-level speed and is useful for accurate timing simulation of digital and mixed-signal VLSI circuits.A block-level representation for analog circuit acceleration is proposed. The proposed methodology will prove to be very useful for mixed-signal circuit design in the deep-submicron (DSM) technology era.

Robust Load-Balanced Location Management Algorithms Arun K. Somani Electrical Engineering Communications Wireless (Microwave, Satellite, Radio) The current IS-41 standard PCS architecture uses a centralized database, the Home Location Register (HLR), to store service and location information of each mobile registered in the PCS network. However, this is a single point of failure, therefore distributed database architectures have been proposed as possible architectures for future mobile networks. The performance of such architectures improves when the load on the databases is balanced. Though distributed architectures offer increased fault tolerance, they suffer from increased query delay (number of databases to be queried to retrieve the required information). The query delay further increases in the presence of database failures. In this talk, we present bounds for the performance of load balanced location management algorithms in the presence of database failures for three standard performance metrics, worst-case query delay, average query delay, and call blocking probability. A load-balanced algorithm tolerating database failures is presented, and its performance measured using the same performance metrics. A robust parallel location management algorithm which queries databases in parallel is then presented, and we derive expressions for the average query delay for the algorithm in presence of failures.

Shadow Caching: An Efficient Error Detection and Recovery Mechanism for Cache Memories by Employing a Small Shadow Cache Arun K. Somani Electrical Engineering Computer Engineering Computer Architectures (Parallel, Distributed, etc.) To reduce bandwidth gap between the processor and memory, cache memories are widely used in modern microprocessors. Considerably reduced clock cycles of the processors and higher circuit densities increase the transient hardware failure rate in the cache memories. As a result, efficient error detection and recovery mechanisms in cache memories are crucial for reliable computing. We have developed a hardware based approach called shadow caching for transient error detection and recovery for the caches of high-performance systems. To check data validity in the main cache, the data is verified against the corresponding shadow cache data synchronously with the cache access. In addition, asynchronous verification on cache idle or AVCI technique is developed to further improve the error detection capability. We show that on an average 86.95\% and 88.28\% error detection coverage are provided by the basic and the AVCI combined shadow caching with only a 1KB shadow cache and chosen parameters, respectively. The proposed AVCI scheme can reduce the error latency as well as provide further improvement in error detection coverage. In this seminar, we will review the need for fault tolerance and present specific solution for fault detection in cache memories. An overview of other research will also be provided.

SIP vs. H.323: A Business Analysis Wind River Electrical Engineering Controls and Systems Robotics, Servomechanisms The VoIP market is highly fragmented with a handful of competing protocols being offered and deployed by numerous vendors. Two such protocols, H.323 and SIP, are often compared and directly compete with each other in the VoIP market. H.323 was an early leader in that market, and continues to be used in a lot of networks. Recent development in the standards groups has seen the Session Initiation Protocol (SIP) emerge as the protocol of choice going forward. This technical paper presents a brief history of the VoIP market as it relates to H.323, introduces the market trends driving the market, compares SIP and H.323 from a technical view, and provides solid market information showing why H.323 may not be a critical piece of new products.

Mono-Phase and Bi-Phase Ultra-Wideband White Paper Electrical Engineering Communications Wireless (Portable and Mobile Radio Systems) In every commercially deployed radio technology, from cellular phones to WiFi (802.11b) to WiFi5 (802.11a), the methods employed to create the signal transport, called the modulation technique, are widespread early on. They can vary from mono-phase to bi-phase to multi-phase approaches. The marketplace drives these disparate approaches to a standard over time, and, typically, the most efficient methods (measured as a combination of factors such as power consumption, cost to build, data rate, transmission distance, and bit error rate) are the ones chosen in the end. This white paper discusses mono-phase and bi-phase Ultra-Wideband (UWB).

IMMSIM++ Steven Kleinstein Philip E. Seiden Bio Engineering Biomedical Neural System Simulation and Modeling The IMMSIM model is actually not a single model, but a collection of models that co-operate with each other to produce a simulation of the immune system. Currently, we simulate the humoral response only, although an effort is under way to add in the cellular response. As it now stands, IMMSIM contains a model of the bone marrow, thymus and a lymph node. Of these, the lymph node model contains the main part of the simulation and is the most interesting part of the IMMSIM model. The bone marrow model and the thymus model consist of simple rate equations along with probability-based filters. While many models in theoretical immunology are differential equation-based, dealing with entire populations of cells and molecules, IMMSIM represents all of the cells and molecules in the system explicitly.

Project Scope Creep: Making widgets without wedgies Larry Gibson Professional Development Engineering Mgmt Project Mgmt, Scheduling, Time Mgmt, Logistics Project engineering/management dominates the world of new product and process development. However, this process, which must be based on a reasonably well-developed statement of purpose and specification, continues to deliver less than expected. A major contributor to this shortfall is project scope creep. Scope creep prevents organizations from meeting the criteria within specification, on time, and at cost. However, not recognizing new market requirements can prove equally costly. This article includes a a case study on project scope creep and the problems encountered between marketing and engineering groups.

The discontinuity of innovation: Building a better mousetrap Alvin P. Lehner Marc H. Meyer Professional Development Career and Personal Development Developing Business and Entrepreneurship Skills What are the approaches that entrepreneurs and corporate innovators use to create products, systems, and services that take on the best-established market leaders? How does an innovator compete against such dominant designs of form and function in the marketplace? The first step is to understand the market while keeping in mind that a dominant design can also have some disadvantages. The corporation creates the winning design, builds consumer awareness, and scales up production volume to meet demand. However, this very mindset, which focuses on volume as opposed to introducing new capabilities, can impede new product innovation. This article addresses how the success of a new product requires a synthesis between understanding the market, using new materials, and simplicity in design to displace an already established framework.

Seven Habits of Effective Communicators Joan G. Nagle Professional Development Career and Personal Development Report Writing, Oral Presentation, etc. If an engineering product or a documentation product is to do its job and serve its purpose, it needs to be well built. Text, illustrations, or tabular material which are not clear, are not going to meet these needs. Often engineering competence does not coexist with the capability of expressing ideas in writing. To compensate, certain skills must be learned, and then practiced, before writing effectively becomes habitual. This article guides us through seven effective steps in becoming powerful communicators and includes tips on how to organize, review, and revise engineering documents.

Fusion Lynn Yarris Materials Science and Engineering Mechanical/Physical Properties Corrosion, Deterioration Fusion is the melding together of lighter atomic nuclei to form heavier nuclei, an action that releases roughly one million times the energy released by the burning of oil. The reason for the continued pursuit of fusion as a commercial source of energy is no joke. The citizens of this country and the rest of the world currently depend upon fossil fuels-oil, gas and coal-for the energy that lights, heats and cools buildings, powers machinery, and drives industrial processes. One day these fuels will be exhausted. Most projections show that severe shortfalls between global energy demands and fossil fuel supplies will begin to be felt toward the end of the 21st century.
