PROJECT 1

Title: PERT Pole System for a University Campus Security
Authors: Daniel Fitzgerald and Maysa Almonayer

Abstract : The purpose of this case study is to apply the fundamentals of system engineering to the operation and selection of the security system used in the university campus. This study will provide a high level representation of the security system used and analyze its efficiency by using the UML notation/semantics and system engineering principles, requirements, use cases, system behavior and system structure, traceability, and optimization and trade-off analysis. In this case study we will describe and deal with one unit of the security system which is the PERT with the video camera, as shown in the picture below.

Our project will analyze one blue light pole on the campus. We will examine the structure and behavior of the telephone, camera, and light associated with the pole. The Security Operations Center and the University of Maryland Department of Public Safety will be users of the system since it will be too complicated to include the departments as part of the system.

PROJECT 2

Title: Optimization of a Cable Lift Operation
Authors: Chris Recla and Nate Tharnish

Abstract: Our project in 641 focused on a ski resort chairlift as a system, with human actors as riders, operators, and ski patrol. Our objective was to optimize the lift for speed, efficiency, cost, etc while maintaining safety. The project, however, focused mainly on the functionality of a single lift.

In 642, we wish to expand this same chairlift idea to optimize a small ski resort containing chairlifts. The objective is to equally disperse skiers around the resort, on both the slopes and lifts. Each slope is categorized under a certain difficulty level. Therefore we assume riders move at a certain rate down the mountain depending on the difficulty level of the slope. Our objective is to design what type and how many lifts best optimize the mountain.

PROJECT 3

Title: System level Design Analysis of Queuing System at Airport Boarding Pass Counter
Author: Bargava Raman Subramanian and Soe Zarni

Abstract: The aim of this project is to model the issuance of boarding pass to passengers in the airports. A queuing model is assumed. The airline deploys a team of trained professionals to handle the issuance of boarding pass. The airline is also allocated a fixed number of counters optimized based on the customersâ~@~Y arrival rate by the airport authority. The passengers come and stand in a line. The person at the front of the queue has his information processed by the first counter that becomes free - and this process continues. We build the system taking the perspective of the airline involved - optimizing the number of crew member deployed, average processing time, etc. In addition to the basic queuing model, a separate processing technique for the issuance of boarding pass to those passengers arriving just around the time of flight's departure is also analyzed.

PROJECT 4

Title: Temperature Control System
Authors: Josemaria Dolores and Francisco Gallo

Website: http://www.wam.umd.edu/~fgallo/ENPM641/Index.htm

Abstract: Design of a system able to maintain the temperature in a room at a certain set point defined through a control panel. A multi-sensing approach has been used to help achieve uniformity of temperature in the room. Also, a multi-diffuser system that is controlled based on the measurements made regulates air flow to compensate internal fluctuations. Control system for the implementation provides various configuration options including the capability of establishing different times for different set points.

PROJECT 6

Title: Building Information Modeling
Author: Abhinav Fatehpuria and Vineet Gupta (in ENSE 621)

Abstract: Defining and categorizing the design requirements of a building from an architectural view point. Preparing the system structure (Class Diagram) at a higher level of abstraction. Defining Validation Parameters to allow the architect to check potential building designs against the specification quickly, easily and in early phases of the design.

PROJECT 7

Title: Airspace Management Decision-Making Tool for Use at a Small Airport
Author: Kerin Thornton

Abstract: Even at small airports, air traffic controllers must maintain a constant awareness of a dynamic situation, which can be enough of a workload to affect decision-making. Any misinterpretation of a given situation may lead to a wrong decision, which has the potential for disaster. The scope of this project is to create a model-based program which air traffic controllers at small airports may use to track aircraft positions, and issue orders accordingly. The program will assist controllers and allow for more efficient airpsace management. It will generate commands for the controller to execute by creating scenarios given the current locations of aircraft within the airport system (airspace, runways, taxiways, terminal gates) and pilot requests (for example, request to take-off).

PROJECT 8

Title: Prognostics System on a Military Wheeled Vehicle
Author: Craig Hershey

Abstract: This system monitors vehicle usage and prognosticates the percentage of component life remaining. All of the monitoring and processing to prognosticate remaining component life is performed on-board the vehicle. The system includes external sensors, embedded sensors, data acquisition unit, data processing equipment and operator alert equipment. External and embedded sensors located on the vehicle generate signals that describe the usage and response of the vehicle to its environment. The signals are digitized and a detailed data quality checking algorithm is performed to determine if the signal is good. After the system ensures the quality of the data, the data is processed for use in damage algorithms. The processes involved are data fusion and data reduction algorithms.

Results from these processes are used in damage algorithms to determine percentage of damage accumulated. Then the percentage-of-life-remaining algorithms use results from the damage algorithms and operator input on expected mission use, or historical data, to estimate the percentage of life remaining for a component.
