. Servicing of the engine-dynamometer system wascompleted as an ETME 499 project. Instrumentation for the fuel consumption measurementswere added and the measurements were carried out. The results indicate that, at constant load, asthe engine speed was increased the fuel consumption increased. The same trend was seen atconstant speed; the fuel consumption increased as the load was increased. Simulated fueleconomy (miles/gal) graph indicate that the engine economy was about flat at higher loads, but,was decreasing slightly at low loads when the engine speed was increased beyond about 1500rpm.IntroductionThe two engine-dynamometer systems, one with a gasoline engine (Fig.1) and the other one witha diesel engine came with the new building when the

The four distinct forms of integration and examplesreported in [1] include a) Portals integration - the shallowest form of integration, which brings potentially dissimilar applications together in a single Web-based portal entry point. b) Business-process integration - a form of integration that coordinates business processes across applications and around enterprise boundaries. One good example is a supply chain management system. It is observed that Web services [3] using XML-based protocols such SOAP (Simple Object Access Protocol) [4], WSDL (Web Service Definition Language) [5], and UDDI (Universal Description, Discovery, and Integration) [6] and their derivatives are becoming

projects as used intheir Senior Design class. The course was a (1-3-2) class which means the students had 1hour of class and 3 hours of on-line lab in a 2 credit course. Thus, for the EngineeringEconomic Design course, students were only required to attend 7 lectures and meet with theirTA twice. Grading was based mainly on their Midterm and Final Presentations with somepoints assigned for three direct participations on-line. Some teams participated more, someless and some the required amount. The course presentations for the Midterm and Final wereto be completed as a team during their “lab” time. The on-line lab component was considereda supplement to their overall team lab time.The three-time, on-line lab participation required of the students

According to Astin3, peer communities have the significant impact onwhether or not college students are retained. Thus, it was important to the success of SFS toestablish an integrated peer community of underrepresented minority student researchers fromboth institutions.Year 1 of SFSInitial program activities primarily focused on identifying qualified undergraduate students whohad already expressed an interest in graduate school or who had the potential to succeed ingraduate school based on their cumulative GPA.

Over the course of the project, SimPlus gainednumerous advanced features such as a global static kernel implementing the Singleton designpattern, and callback-method automated event processing.1. IntroductionSimulation tools aims at facilitating the tasks of analysts or engineers. Without such tools,writing a simulation program often becomes difficult and requires reinvention of the wheel at thebeginning of each project. As a result, simulation tools have become very popular for industrial,defense, and educational applications.For educational purposes, the final class project of

Student exit interviews were reviewed andapproximately 60 current engineering students met with task force members for input.

RAIDb-0 is similar to common distributed databasesystems, such as Oracle RAC5, PostGreSQL Replication Project, and Emic Application Clustersfor MySQL6. Like these systems, stored data in a RAIDb-0 system is simply distributed amongnodes. No replication or duplication of information is performed. Crecchet indicates, “[that]like for RAID [Redundant Array of Independent Disks] systems, the Mean Time BetweenFailures (MTBF) of the array is equal to the MTBF of an individual database backend, dividedby the number of back-ends in the array.1

To address similar issues, health-monitoring (HM) concept is used in many engineeringdisciplines in various contexts, but is not yet exploited fully in CE practice. While most civilengineers recognize forensic engineering, HM and its system-identification are yet outside therealm of applications in this profession. Given these challenges, four logical research topics to solve infrastructure problems are: 1)full-scale testing of structures and/or subassemblies to understand their behavior under adverseloadings and implement novel strategies to enhance performance; 2) developing improvedmaterials and testing procedures for small-scale models which are cost effective
