Robotic Manufacturing Cell: An Analysis Of Variables Affecting Performance, Elvis Alicic
Robotic Manufacturing Cell: An Analysis Of Variables Affecting Performance, Elvis Alicic
Dissertations and Theses @ UNI
Analyzing the performance of manufacturing cells is a well established concept. The justification for conducting thorough analyses of manufacturing cells comes from the known advantages it can provide, including performance improvement and production planning improvement, both current and future. This study focuses on assessing the variables affecting performance of a robotic manufacturing cell through the measure of throughput. Initially, simulation modeling is utilized to model an existing robotic cell and compare the output to actual production output from the same cell. Additionally, general regression modeling is employed to analyze the following variables and their effect on throughput: machine downtime, off-plan …
Using Metarules To Integrate Knowledge In Knowledge Based Systems. An Application In The Woodworking Industry, Alvaro Villavicencio
Using Metarules To Integrate Knowledge In Knowledge Based Systems. An Application In The Woodworking Industry, Alvaro Villavicencio
Dissertations and Theses @ UNI
The current study addresses the integration of knowledge obtained from Data Mining structures and models into existing Knowledge Based solutions. It presents a technique adapted from commonKADS and spiral methodology to develop an initial knowledge solution using a traditional approach for requirement analysis, knowledge acquisition, and implementation. After an initial prototype is created and verified, the solution is enhanced incorporating new knowledge obtained from Online Analytical Processing, specifically from Data Mining models and structures using meta rules. Every meta rule is also verified prior to being included in the selection and translation of rules into the Expert System notation. Once …

The Design And Evaluation Of Wireless Sensor Networks For Applications In Industrial Locations, Hameed Madwar
Dissertations and Theses @ UNI
In manufacturing industries, there exist many applications where Wireless Sensor Networks (WSN's) are integrated to provide wireless solution for the automated manufacturing processes. It is well known that industrial environments characterized by extreme conditions such as high temperature, pressure, and electromagnetic (EM) interference that can affect the performance of the WSN's. The key solution to overcome this performance issue is by monitoring the received Signal Strength Index (RSSI) at the received sensor of the WSN device and track frame error rate of wireless packets.
ZigBee is a wireless sensor network (WSN) standard designed for specific needs of the remote monitoring …
Ergonomics Evaluation Of Task Demands Among Kitchen Staff, Jaqueline Pereira Da Silva
Ergonomics Evaluation Of Task Demands Among Kitchen Staff, Jaqueline Pereira Da Silva
Dissertations and Theses @ UNI
The purpose of this study was to evaluate the workplace demands faced by a group of kitchen staff at six dining centers and to survey musculoskeletal complaints among this sample of workers. The dining centers were located in six different public elementary and middle schools in a city in the south of Brazil. This research was developed following qualitative research design, and the researcher made use of the “Activity Oriented Ergonomics (AOE) methodology.
The AOE focuses on the work analysis that evaluates real work situations that allows a reassessment of work demands. In this case the chosen methodology was a …
Coolant Fluid In A Turning Operation: Soybean Coolant Fluid In Different Concentrations Versus Petroleum Coolant Fluid, Mary Esther Eckman
Coolant Fluid In A Turning Operation: Soybean Coolant Fluid In Different Concentrations Versus Petroleum Coolant Fluid, Mary Esther Eckman
Dissertations and Theses @ UNI
The manufacturing sector today's market felt the need to reduce costs along with the ability to be more "green."
Traditionally petroleum based fluids are used in the manufacturing industry. However they are environmentally more harmful as well as cause significant hazards to the operator. This thesis will provide a case study for this sector to become more environmentally friendly with the use of a soybean based cutting fluid. To prove the point a number of tests were performed turning 4140 steel on a CNC turning center. A number of tests were conducted to provide a comparative study of dry, petroleum …

The Integration Of Wind Energy In The Electrical Grid During The Contingencies, Islam Ali
Dissertations and Theses @ UNI
As wind energy expansion develops, there are also many problems and challenges to connect the wind farms to the grid. There are many different interactions during the connection like the voltage flicker, harmonics, transient, short circuit current, frequency, and safety protection. Those problems may affect the performance of the grid and may cause serious problems. This study investigates the grid-connection problems for the wind turbines and offers appropriate solutions. This study provides a simulation for the power system during the faults. The electrical grid in the simulation contains generators and wind turbines which are connected to the grid. It also …

Modeling And Analysis Of Grid-Connected Solar-Wind Hybrid Power System, Sultan Altamimi
Dissertations and Theses @ UNI
Renewable energies are considered to be a significant part of the energy mix to assist the existing electricity demand and the future of electrical generation. Electrical power simulation software is increasingly being used to answer and determine the source of potential problems in the actual power system. To have a better understanding of an electrical power system, it is essential to validate all the components through simulation within an environment that allows accurate modeling of all power system components. This research presents modeling and analysis of an actual grid-connected solar-wind hybrid system at University of Northern Iowa campus in Cedar …
