Title : PCS Cell Phone
Authors:
Young-Sil Shin and John Saah
Abstract : Our project will involve an overall description of the system, its features and capabilities, as well as the main components within the system. Our project will also include trade-off studies of the 4 main design variables: RF radiation emmissions, battery life, portability/size, and cost. Nowadays, these are the 4 main variables that consumers look at when purchasing a cll phone.
Our idea is to provide overall project analysis in creating a PCS cell phone "line of products" which will involve various versions that offer different levels of each of the 4 main design variables.

Title: A Systems Engineering Approach to the
Design of an Answering Machine Product Line
Authors: The Shady Grove Team:
Elizabeth Koza ,
Rocio Salas-Lopez
and
Vanessa Virtudazo
Abstract : The paper will investigate multiple answering machine designs through the use of Systems Engineering methodologies, paradigms, and tools. By creating a pattern design for an answering machine that turns into several variations of the product, we will be able to satisfy diverse consumer sectors with effectiveness of design and manufacturing. A modular design approach and the concept of re-use will also be considered in order to minimize cost. The benefits of our chosen approach will be demonstrated through optimization and trade-off analysis.

Title:
A Systems Engineering Approach to the Design of an Automobile's Automatic Temperature Control
Authors: Hilton Thom and Keisha Harris
Abstract : This report will attempt to show and identify an automatic temperature control unit for an automobile by using a System Engineering point of view. System modeling, methodology, and techniques will be ascertained by and overall system engineering process. Traceability, trade-off Analysis, and the determination of customization can be an option if system is manufactured.
Title:
Automotive Vehicle Suspension Systems
Authors:
Winston Harris
Abstract : Automotive vehicle suspension systems in today's engineering environment are no longer simple stand-alone designs. Rather they are evolving into an integration of technologies that serve to compose a complex system of systems. These systems include the spring, the upper and lower 'A' arms, the damper, the rotor, the brake caliper, the hub plate, the bearing spindle, the bearings, the rim spindle, the rim, the tire, and the hardware that holds it all together. Ideally the application of a system model imposed on these suspension sub-systems could handle every application in the environment. However, it is necessary to narrow the scope of this endeavor in order to focus on the system modeling aspect of this problem. The assumptions to be made to simplify this system are as follows:
With these constraints in mind, the design elements of the sub-assemblies will be allowed to vary based on user-defined input conditions. Obviously, it is not possible to define design a suspension system that meets every need, but through this paper, it will be shown that a top-level system that makes use of a Unified Modeling Language (UML), can define the problem and all of its variants. By having a fully defined system, it will be shown given any set of inputs, a solution is obtainable with this system model.
Title:
Portable MP3 Player
Author:
Mingjia Dai
Abstract: This project ... Music recordings have progressed so far from the days of vinyl. Now, if you want to expand your music collection fast and easy, an MP3 player is the handiest tool to work with. They're compact and easy to tote around, and can organize hundreds of tunes to play at your whim. How much you want to spend, and how much memory you'll need is up to you (our favorite can hold up to 1,000 songs). Browse through our selection of players and see if there's one worthy of holding your music collection.
MP3 stands for MPEG1 layer 3 audio. MP3 is a compression algorithm that is used to compress audio files. Audio data on conventional CDs is very large (sometimes greater than 50 megabytes). After this .wav file undergoes MP3 compression, it is reduced in size by around a factor of ten. This makes .MP3 files much smaller (around a megabyte a minute depending on the quality). Because of their small size and incredible quality, .MP3 files have become very popular to download from the Internet.
An MP3 player offers several advantages over most other types of portable audio players such as cassette, CD, and MiniDisc players. First, you can easily drag and drop songs around on your PC to build playlists that contain just the songs you want. Second, even early MP3 players are already quite compact -- typically smaller than an audiocassette and weighing just a few ounces. Finally, because many MP3 players have no moving parts at all, you can forget about skipping and all the buffering schemes that never seem to fully fix the problem on portable CD players. The biggest advantage portable MP3 players have over CD players is that there are no moving parts.
Still, with a variety of storage formats, bundled software, interfaces, and file formats, design for a portable MP3 player is a lot harder than a Walkman.
Title:
A Model Breast Pump of the Systems Engineering Mother
Author: Christi Montgomery
Abstract: This project will focus on the function and design of modern portable breast pumps. The author will strive to find the base-line requirements driving the design of current consumer-market pumps, and will seek to find alternative design methods which will result in equal or great consumer satisfaction than currently exists.
Title:
System-Level Design of an Automatic Vending Machine
Author:
Deep Saraf and
Vimal Mayank
Abstract: We plan to make a self-service automated ordering system. In this project when an actor enters into a restaurant, he does not have to wait for a person to attend him. He can make his own order on a touch screen monitor at the counter. He will also make the payment through credit card and the system will check for the authenticity of the card and deduct the ordered amount. Then the system will pass on the message in the kitchen for the final order. Here we can change the settings or the menu or the prices and this will be reserved by the administrator.
Title: Power Driven Roll-Up (Garage) Door Opener
Authors:
Nahid Araghi and
Charles McLendon
Abstract: This project will be a system-level design for opening and closing a garage door for a business or residence from inside or outside the structure, or inside a vehicle (whether the vehicle is inside or outside the structure).
Title:
Variable Message System (VMS) Model
Authors: Ankur Mehta and
Saurav Singh
Abstract: Variable message signs (VMS) are traffic control devices used to provide motorists en- route traveler information. They are commonly installed on full-span overhead sign bridges, post-mounted on roadway shoulders, and overhead cantilever structures. The information is most often displayed in real-time and can be controlled either from a remote centralized location or locally at the site. VMS are designed to affect motorist behavior to improve traffic flow and operations. Traveler information displayed on VMS may be generated as a result of a planned or unplanned event, which is programmed or scheduled by operations personnel. Examples of traveler information include:
The objective of providing the information is to allow the motorist time to avoid an incident, prepare for unavoidable conditions, or to give travel directions.
Title:
Systems Engineering for a Traffic Light Controlled Intersection
Authors:
Saini Yang and
Masoud Hamedi
Abstract: The purpose of this project is to develop a series of systems model for traffic passing through a 4-way intersection, controlled by traffic light. We will assume that arrangement of traffic lights and road lanes is fixed and that the lights switch from red to green to amber in a regular repetitive pattern. Moreover, we assume that driver behavior is constrained by the road rules (we keep this part really simple) and the desire to avoid vehicle collisions.
