The Development of the New Feeder System: Applying the System Development Life Cycle Methodology
Get PDFMy graduate project proposal is the development of the new Feeder system. The new Feeder system is comprised of five individual feeders, which are the Hourly Payroll, Salary Payroll, Stores, Job Labor and Accounts Payable feeders. My task is to effectively apply the methodology of the system development life cycle to this project. The purpose of this paper is to demonstrate my ability to identlfy and solve a real world problem using the theories and skills learned in the
Master of System Analysis program. This paper begins by focusing on the problems that resulted in the development of a new Feeder system. It answers the question of 'Why should a new
system be developed?' Also, the paper outlines the methodology applied in the development of the new system. This addresses the question of "How did I develop the new system?" Next, I
address the learning experiences in developing this project. In addition, I will outline the special features and the costbenefit analysis of the new system
GPS Civil Signal Self-Interference Mitigation During Weak signal Acquisition
Get PDFCurrent global positioning system receivers can acquire weak satellite signals with = 15 dB/Hz if there is no self-interference from other strong satellite signals. This correspondence presents a computational efficient partitioned subspace projection method to mitigate the self-interference. The method is evaluated using simulated signals and a block-based weak signal acquisition algorith
The Integration of Software Development Tools
Get PDFThe effectiveness of software development tools can be dr
creased by their integration (i.e. their cooperation). This paper discusses the problems to be overcome in integration of tools, and a categorization of the degree of tool integration. The continuum from loose to tight integration is parameterized. An informal method is described to apply these parameters
to tools in order to determine some nxeasure of their ability to be integrated
Software Development for Manufacturing Systems- Language and Networking Issues
Get PDFWe have witnessed unprecedented changes in the industrial world with the advent of computers and the field of manufacturing is no exception. With the boom of microcomputers, th eir usage in manufacturing systems was realized at every level- from the shop floor level to the administrative and management layers. This paper deals with the software development issues that a software engineer has to take into account when analyzing, designing, and implementing software for manufacturing systems. Two important criteria that one has to consider are the real-time requirements and the device indepemdent abstractions that such software has to provide to the end-user, since it is reasonable to expect an end-user to know very little about the software intricacies. Two specific aspects of manufaturing software are discussed indetail here. The first part discusses a language with an object oriented flavor for programming manufacturing systems. In particular, some of the design aspects and implementation issues are discussed. The other part describes the networking issues that are specific ot the manufaturing environment. A prototype manufacturing system developed as a part of the p roject is used as a model to explain the various concepts and issues. A detailed description of the new language, Cell Programing Language (CPL), developed for the prototype is also included
"State-based Control Language a State-based, Interrupt-driven, Concurrent Language with Error Detection and Recovery"
Get PDFA programming environment to support interactive, concurrent programming for Miarni University's Flexible Manufacturing System is described. The environment is intended to replace the existing extended cell programming language (ECPL), which was sequential in nature, to a state-driven one in order to
support concurrency. The system has been altered from being sequential to reactive and is interrupt driven. This also enhances error detection and recovery capabilities. This paper will address the topics of Flexible Manufacturing Systems (FMS) and programming languages for manufacturing control, and will then develop a criteria for analyzing a FMS programming language. Based on that criteria, the former ECPL language will be discussed and analyzed to address problems in ECPL. The paper will conclude with an analysis of the new system outlining areas for further investigation and improvement
Development of an Object-Oriented High-Level Language and Construction of an Associated Object-Oriented Compiler
Get PDFComputerized automation has long past been in practice, and engineers are developing ways and means of improving strategies to achieve better performance. Related search is concentrated on developing methords to diversify the application of computing technologies by bringing software and its field of application close together. The idea is to eventually create a software configuration that makes itself transparent to the user by mapping reality onto the computer's monitor. This paper is a report on a portion of and interdisciplinary project that attempts to apply state-of-the-art software techniques in the design of an integrated programming environment for manufacturing purposes. The portion of the project described in this paper is concerned with two aspects: designing a special purpose object-oriented high-level language for programming a classroom research laboratory for manufacturing students and faculty, and designing and implementing an object-oriented compiler to allow students to write programs using this language. The purpose of the project is to integrate manufacturing devices and cells with the existing computer network to provide a flexible manufacturing system
A Simple System Dynamics Model For the Wildlife and Fish Resource
Get PDFThis research aims to build a dynamic model to describe the major relationships within the "Wildlife and Fish" element of the Forest Service. Our purpose is to capture the major relationships so that the model is capable of reproducing the dynamic behavior patterns exhibited by the important Wildlife and Fish variables. Such a model should include not only the "physical variables" (such as "acres prescribed burned" or "number of water developments") but also the management
decision processes which influence those variables. Once the major "physical relationships" and "decision relationships" are appropriately described in the model, the latter should be able to exhibit the basic dynamic performance patterns observed in the Wildlife and Fish (WhF) sector. Then, such a model can be used a s a "management laboratory". It is possible to explicate why and how particular performance patterns are exhibited by certain variables. If some of these performance patterns aril undesirable, the model can help managers generate alternative policies to eliminate those undesired patterns. By using such dynamic models for Wildlife & Fish sector it is possible to
investigate the aedium-to-long-term implications of various alternative management policies
Full-Cycle Assessment of Critical Thinking in an Ethics and Science Course
Get PDFEnhancing critical thinking skills for undergraduate students is important across the curriculum and between disciplines. We report on a method of improving critical thinking skills, which was studied through an Ethics and Science First-Year Seminar course. We used full cycle assessment over a three-year period to assess students’ development and to modify the course teaching and assignments with the goal of increasing student development of critical thinking skills. Data were obtained from student writing throughout the semester during each offering. Modest, but significant, overall gains of ~0.7 on a 4 point scale are reported between early and midterm assignments in the course using a seven trait assessment rubric. Key factors that contribute to the increase in critical thinking skills are identified including peer review, scaffolded assignments, and the use of a grading rubric for each assignment
Comprehensive Description and Critical Analysis of Object-Oriented Software Development
Get PDFoai:dspace.lib.miamioh.edu:2374.MIA/213Object-orientation and the object model underlie a simple, intuitive, and useful approach to software development that has great potential for significantly improving the software development process. Object-orientation unifies activities, such as analysis and design, that currently largely independent and somehwat incompatible. Despite its simplicity, a sroud of msytery surrounds this approach. The difficult often encountered when learning and understanding object-oriented methods sems partly from the capricious and improper use of object-oriented jargon in conversation and in the literature. This paper explores the foundations of the object model, defines the associated terminology in concrete terms, and gives an overview of various object-oriented methods as they relate to the software lifecycle
Signature Files: An Integrated Access Method for Formatted and Unformatted Databases
Get PDFThe signature file approach is one of the most powerful information storage and retrieval techniques which is used for finding the data objects that are relevant to the user queries. The main idea of all signature based schemes is to reflect the essence of the data items into bit pattern (descriptors or signatures) and store them in a separate file which acts as a filter to eliminate the non aualifvine data items for an information reauest. It provides an integrated access method for both formattid and formatted databases. A complative
overview and discussion of the proposed signatnre generation methods and the major signature file organization schemes are presented. Applications of the signature techniques to formatted and unformatted databases, single and multiterm query cases, serial and paratlei architecture. static and dynamic environments are provided with a special emphasis on the multimedia databases where the pioneering prototype systems
using signatnres yield highly encouraging results
