Empirical Model-Based Control For End Milling Process, Abdelmalak Salib Dec 2000

Empirical Model-Based Control For End Milling Process, Abdelmalak Salib

Dissertations

The main objective of this research is to develop an empirical model-based control mechanism to maintain a fine surface finish quality by maintaining on-line cutting force values. The proposed model has been developed to present the control model constraints, by varying the machining parameters to control the force output to be constant. To relate the surface finish and the cutting force in the end milling machining process, a design of experiment has been conducted to determine the effect of two different materials (aluminium and steel) and the machining parameters (feed rate, spindle speed) at a predefined depth of cut.

Predicting Employee Compliance With Safety Regulations, Factoring Risk Perception, Yenny Farinas Diaz Nov 2000

Predicting Employee Compliance With Safety Regulations, Factoring Risk Perception, Yenny Farinas Diaz

FIU Electronic Theses and Dissertations

The purpose of this research was to develop a methodology that would evaluate employees’ personality traits, demographic characteristics, and workplace parameters to predict safety compliance along with the moderating effect of risk perception.

One hundred and twenty five employees of a manufacturing facility were given questionnaires to gather their demographic and perception information. Surveys were also used to measure their personality characteristics, and periodic observations were recorded to document employee’s safety compliance. A significant correlation was found between compliance and the worker's perception of management's commitment to safety (r = 0.27, p < 0.01), as well as with gender (r = -0.19, p < 0.05). Females showed a significantly higher average compliance (78%), than males (69%). These findings demonstrated the value of developing a model to predict safety behavior that would assist companies In maintaining a safe work environment, preventing accidents, ensuring compliance, and reducing associated costs.


Proposed Design Modifications To Reduce Risk Of Operating Rotary Field Mowers, Katie L. White, Larry G. Wells, Scott A. Shearer, Larry R. Piercy Nov 2000

Proposed Design Modifications To Reduce Risk Of Operating Rotary Field Mowers, Katie L. White, Larry G. Wells, Scott A. Shearer, Larry R. Piercy

Biosystems and Agricultural Engineering Faculty Publications

The primary objective of this project was to reduce risk of injury associated with operating a rotary mower driven by a tractor power take-off (PTO) by developing and evaluating design improvements and determining their economic feasibility. Researchers have concluded that alteration of machinery design has a greater impact on the reduction of accidents than safety training. Implementation of an Operator Presence Sensing System (OPSS) and removal of the PTO are the two injury-reducing, engineering modifications evaluated by this research. Hydraulic power allows this to occur by providing dynamic braking, few moving parts (removal of the PTO), and controllable power. A ...

Comparison Of Light Rail Transit With Bus Semirapid Transit, Vukan R. Vuchic Oct 2000

Comparison Of Light Rail Transit With Bus Semirapid Transit, Vukan R. Vuchic

Departmental Papers (ESE)

Selection of transit modes is one of the most important decisions in the transit planning process. A particularly important decision is the selection between bus and rail modes, because it influences the type of service that will be offered and, more importantly, the role transit will play in the city. Ultimately, such a decision has an impact on the quality of life in the city. It is therefore necessary to include in the selection process the physical and economic characteristics of modes, as well as the quality of service, attraction of passengers and the impacts of the transit system on ...

An Analysis Of The Influence Of Age And Ionizing Radiation On Cognitive Performance, Elizabeth L. Gerhardt

Theses - Daytona Beach

This thesis was designed to study whether age has a significant effect on cognitive test results among persons exposed to ionizing radiation. The data for this investigation came from the fourth year of a 1995-98 longitudinal study of subjects exposed to radiation from the 1986 Chernobyl, Ukraine, nuclear power plant accident. Accuracy and efficiency scores from four cognitive tests taken by 84 Ukrainian volunteers were divided into two age groups and three radiation dosage groups for analysis. The results of this study found that decrements in human performance on tasks involving spatial processing increase with age in persons who have ...

Swarm Engineering, S. Kazadi '90 May 2000

Swarm Engineering, S. Kazadi '90

Doctoral Dissertations

Swarm engineering is the natural evolution of the use of swarm-based techniques in the accomplishment of high level tasks using a number of simple robots. In this approach, one seeks not to generate a class of behaviors designed to accomplish a given global goal, as is the approach typically found in mainstream robotics. Once the class of behaviors has been understood and decided upon, specific behaviors designed to accomplish this goal may be generated that will complete the desired task without any concern about whether or not the final goal will actually be completed. As long as the generated behaviors ...

Design, Modeling And Preliminary Control Of A Compliant Hexapod Robot, Uluc Saranli, Martin Buehler, Daniel E. Koditschek Apr 2000

Design, Modeling And Preliminary Control Of A Compliant Hexapod Robot, Uluc Saranli, Martin Buehler, Daniel E. Koditschek

Departmental Papers (ESE)

We present the design, modeling and preliminary control of RHex, an autonomous dynamically stable hexapod possessing merely six actuated degrees of freedom (at the hip attachment of each leg). Our design emphasizes mechanical simplicity as well as power and computational autonomy, critical components for legged robotics applications. A compliant hexapod model, used to build a simulation environment closely informed the design and construction of the physical machine and promises to inform, similarly, our future analysis as well. Simulations and experiments show that RHex can achieve dynamically stable walking, running and turning with very simple clock driven open-loop control strategies.

Event Driven Parts Moving In 2d Endogenuous Environments, C. Serkan Karagoz, H. Isil Bozma, Daniel E. Koditschek Apr 2000

Event Driven Parts Moving In 2d Endogenuous Environments, C. Serkan Karagoz, H. Isil Bozma, Daniel E. Koditschek

Departmental Papers (ESE)

This paper is concerned with the parts’ moving problem based on an event-driven planning and control. We are interested in developing feedback based approaches to the automatic generation of actuator commands that cause the robot to move a set of parts from an arbitrary initial disassembled configuration to a specif ed final configuration. In the Phase I of this project, a composite algorithm that reactively switches between different feedback controllers has been shown to induce a noncooperative game being played among the parts being manipulated. This paper describes experimental results with EDAR - Event-Driven Assembler Robot - developed for moving parts based ...


A Brachiating Robot Controller, Jun Nakanishi, Toshio Fukuda, Daniel E. Koditschek Apr 2000

A Brachiating Robot Controller, Jun Nakanishi, Toshio Fukuda, Daniel E. Koditschek

Departmental Papers (ESE)

We report on our empirical studies of a new controller for a two-link brachiating robot. Motivated by the pendulum-like motion of an ape's brachiation, we encode this task as the output of a "target dynamical system." Numerical simulations indicate that the resulting controller solves a number of brachiation problems that we term the "ladder," "swing-up," and "rope" problems. Preliminary analysis provides some explanation for this success. The proposed controller is implemented on a physical system in our laboratory. The robot achieves behaviors including "swing locomotion" and "swing up" and is capable of continuous locomotion over several rungs of a ...

An Integrated Engineering-Computation Framework For Collaborative Engineering: An Application In Project Management, Hisham Mohamed El-Sayed Abdelsalam

Mechanical & Aerospace Engineering Theses & Dissertations

Today's engineering applications suffer from a severe integration problem. Engineering, the entire process, consists of a myriad of individual, often complex, tasks. Most computer tools support particular tasks in engineering, but the output of one tool is different from the others'. Thus, the users must re-enter the relevant information in the format required by another tool. Moreover, usually in the development process of a new product/process, several teams of engineers with different backgrounds/responsibilities are involved, for example mechanical engineers, cost estimators, manufacturing engineers, quality engineers, and project manager. Engineers need a tool(s) to share technical and ...
