Analysis of nonlinear behavior in novel pneumatic artificial muscles

Title of Thesis: ANALYSIS OF NONLINEAR BEHAVIOR IN NOVEL PNEUMATIC ARTIFICIAL MUSCLES Erica Grace Hocking, Master of Science, 2012 Thesis Directed By: Professor Norman M. Wereley, Department of Aerospace Engineering Motivated by the excellent actuator characteristics of pneumatic artificial muscles (PAMs), two novel actuators based on this technology were developed for applications where traditional PAMs are not suitable. The first of these actuators is a miniature PAM that possesses the same operating principle as a full-scale contractile PAM, but with a diameter an order of magnitude smaller. The second actuator, a push-PAM, harnesses the operational characteristics of a contractile PAM, but changes the direction of motion and force with a simple conversion package. Testing on these actuators revealed each PAM’s evolution of force with displacement for a range of operating pressures. To address the analysis of the nonlinear response of these PAMs, a nonlinear stress vs. strain model, a hysteresis model, and a pressure deadband were introduced into a previously developed force balance analysis. The refined nonlinear model was shown to reconstruct PAM response with higher accuracy than previously possible. ANALYSIS OF NONLINEAR BEHAVIOR IN NOVEL PNEUMATIC ARTIFICIAL MUSCLES
PRELIMINARY ASSESSMENT OF THE INCREASED SPEED LIMIT ON RURAL INTERSTATE HIGHWAYS IN ILLINOIS (ABRIDGMENT)

In May 1987, a 65-mph speed limit was posted on rural Interstate highways in Illinois. The effect of the change in vehicle speeds on the incidence of accidents is assessed for the first year. The method consisted of using 5 years of data collected before the new speed limit and subjecting these data to linear regression to project the number of accidents had there been no change in the posted speed limit. The projected number of accidents of each type was then compared with the reported numbers for the period of the assessment. Average speeds of passenger vehicles on the rural Interstates increased from 59.8 mph during the preceding year to 61.8 mph during the initial 12 months of the increased speed limit. The number of fatal accidents (expected versus reported) increased on each of the three different types of highways (15.2% on rural Interstates, 20.3% on urban Interstates, and 2.9% on the primary system of highways). Most of the increase in fatal accidents on the rural Interstates may be attributed to the increase in fatal pedestrian accidents and fatal accidents involving drinking and driving. Results indicate that the higher posted speed limit in Illinois did not have a clearly noticeable or an obviously adverse effect on fatal accidents during its first year.
The effect of dynamic and static stretching on performance

TITLE: THE EFFECT OF DYNAMIC AND STATIC STRETCHING ON PERFORMANCE Researcher: Jaclyn C. Oakley Advisor: Dr. Ben Reuter Date: 4/20/07 Research Type: Master’s Thesis Purpose: The purpose of this study was to examine the differences between three stretching protocols on the performance of the T-test for agility in Division III collegiate football players. Problem: Recent research has found that the acute effects of stretching may have negative results on both performance. Method: Eighteen male subjects from a Division III football team, volunteered for this study. Each subject was tested on six separate days. All subjects performed a 5 minute jog warm-up first. Subjects then rested for two minutes. Subjects then performed their randomly assigned protocol. They had another rest period of two minutes. They performed two trials of the Ttest for agility with one minute rest in between trials. The best time was recorded. Findings: A significant effect was found (F(2,34)= 5.518, p < . 001. ) Conclusion: This study revealed that the type of stretching protocol has a significant effect on agility performance in Division III collegiate football players.

RISK ANALYSIS OF SLOPES AND ITS APPLICATION TO SLOPES IN CANADIAN SENSITIVE CLAYS

An interesting risk analysis of clay slopes for short-term and long-term analysis, including pore water pressures in sensitive clays, is presented. Application of the analysis to typical clay slopes indicates the contribution of different soil parameters and model uncertainty to the total variance and probability of stability failure. Current design factors give a relatively high risk of failures in practice and are justified on economic grounds except for embankment dams. /Author/
Evolving a roving-eye for go revisited

This thesis presents a further development of Neuroevolution of Augmenting topologies(NEAT)[21]. The author augments NEAT by parallelizing the fitness evaluation of the phenotypes enabling the method to be utilized on highly complex fitness evaluations by running it on a cluster. This augmented version of NEAT is then applied to the inherently complex problem of the Go board game, by using the Gnugo (See www.gnu.org/software/gnugo/.) software package as a fitness evaluator. The performance increase also enables the author to follow up on the predictions of Kenneth Stanleys previous discussions that co-evolution will help evolve a more general Go player, rather than the predicted evolved behaviour of specializing in beating Gnugo.
Recycling awareness among undergraduate student under KAED environmental education: a case study of KAED’s students recycling behaviour

The combination of the Muslims practices of conservation and the environmental education in KAED ensured the recycling awareness of the students in the faculty. Recycling awareness among students helps in cleaning up the environment and participating in the daily natural life cycle to achieve sustainability. The amount of waste carried out of the studio step in the faculty everyday could be a real problem. Students work in the studio most of the time, everyone comes with food and drinks plus the paper used for the projects and model making. The purpose of the research was to analyze the relationship between the recycling awareness of the students and the environmental education they undertake in KAED. The study examined the differences in recycling awareness among the students of KAED and focused towards the students’ recycling awareness in relation to the year of study and the environmental studies they undertake. Chi-square and correlation were calculated for the data to determine the difference in recycling awareness among students in different years of study with respect to gender, department, attitude, facilities location and recycling knowledge undertaken in the faculty. The findings showed that the students’ recycling awareness is significantly related to the year of study. Gender and department showed no relation with the recycling awareness of the students. The results also showed that facilities location played an important part on awareness. Recommendations included intensifying the environmental educational programs to plan for more sustainable environments and increasing the number of recycling bins for better accessibility. Future studies are recommended to focus on the enhancement of the environmentally friendly behavior with respect to sustainable development.

A Review on Natural Disaster Detection in Social Media and Satellite Imagery Using Machine Learning and Deep Learning

A disaster is a devastating incident that causes a serious disruption of the functions of a community. It leads to loss of human life and environmental and financial losses. Natural disasters cause damage and privation that could last for months and even years. Immediate steps need to be taken and social media platforms like Twitter help to provide relief to the affected public. However, it is difficult to analyze high-volume data obtained from social media posts. Therefore, the efficiency and accuracy of useful data extracted from the enormous posts related to disaster are low. Satellite imagery is gaining popularity because of its ability to cover large temporal and spatial areas. But, both the social media and satellite imagery require the use of automated methods to avoid the errors caused by humans. Deep learning and machine learning have become extremely popular for text and image classification tasks. In this paper, a review has been done on natural disaster detection through information obtained from social media and satellite images using deep learning and machine learning.
A Field Modeling Approach to Prediction of Hot Gas Movement Induced By Marine Compartment Fires

Predicting smoke flow movements in marine and offshore compartment fires is still a challenging endeavor for fire safety researchers. The research described in this paper is an effort to apply the computational fluid dynamics (CFD) model to numerically simulate such smoke flows. The present computational model involves a CFD code to solve 3-dimensional turbulent buoyancy-driven flows using a set of low-Mach-number approximated governing equations, a turbulence model based on large eddy simulation, and a combustion model to calculate the heat release rate from fires. A pool fire is simulated and the results are compared to the measured data of a laboratory experiment. A simulation of an engine room fire on a coastal LPG ship is also presented as an example of applications.
Broadband high-efficiency reflective LTC polarization converter with temperature control in the visible range

In practical applications, the linear to circular (LTC) polarization conversion of electromagnetic waves is of great significance. In this work, we designed a broadband high-efficiency reflective LTC polarization converter with temperature control in the visible range. Each periodic unit of the LTC polarization converter is composed of a gold mirror, a dielectric layer, a wide L-shaped gold plate and a narrow anti-L-shaped VO2 strip. The results show that the conversion efficiency can reach 0.9 in the visible range, and the switch of polarization converter can be controlled by VO2. The linear to circular polarization converter has potential applications in stealth technology, electromagnetic measurement.
Process simulation and quality evaluation of incremental sheet forming

Single Point Incremental Forming (SPIF) is a promising sheet-metal-forming process that permits the manufacturing of small to medium-sized batches of complex parts at low cost. It allows metal forming to work in the critical ‘necking-to-tearing' zone which results in a strong thinning before failure if the process is well designed. Moreover, the process is complex due to the number of variables involved. Thus, it is not possible to consider that the process has been well assessed; several remaining aspects need to be clarified. The objective of the present paper is to study some of these aspects, namely, the phenomenon of the wall thickness overstretch along depth and the effect of the tool path on the distribution of the wall thickness using finite element simulations. Abstrak: Pembentukan Tokokan Mata Tunggal (Single Point Incremental Forming (SPIF)) merupakan satu proses pembentukan kepingan logam yang membolehkan pembuatan dalam jumlah yang kecil hingga sederhana, bahagian-bahagian yang kompleks pada kos yang rendah. Jika proses ini direka dengan baik, kaedah ini membolehkan pembentukan logam yang baik terhasil. Jika tidak, semasa peringkat zon kritikal ‘perleheran-ke-pengoyakan' menyebabkan penipisan keterlaluan yang boleh menyebabkan logam tersebut rosak. Tambahan pula, proses ini agak kompleks, kerana ia melibatkan beberapa pemboleh ubah. Maka, walaupun proses ini telah dinilaikan seeloknya; masih terdapat beberapa aspek lain yang perlu diperjelaskan. Objektif kertas ini dibentangkan adalah untuk mengkaji beberapa aspek tertentu, seperti, ketebalan dinding regangan berlebihan di sepanjang kedalaman dan kesan tool path (beberapa siri posisi koordinat untuk menentukan pergerakan alatan memotong ketika operasi memesin) terhadap pengagihan ketebalan dinding menggunakan simulasi unsur terhingga.
Experimental investigation of helicopter vibration reduction using rotor blade aeroelastic tailoring

A wind tunnel investigation has been conducted to parametrically investigate the effect of blade nonstructural mass on helicopter fixed- and rotating-system vibratory loads. The data were obtained using Mach- and aeroelastically-scaled model rotor blades which allowed for the addition of concentrated nonstructural masses at multiple points along the blade radius. Testing was conducted for advance ratios ranging from 0.10 to 0.35 for ten blade mass configurations. Three thrust levels were obtained at representative full-scale shaft angles for each configuration. Results indicate that proper placement of blade nonstructural mass can provide reductions in fixed-system vibratory loads, but that correct mass placement and the loads reduction realized are dependent upon flight condition. The data base obtained with this investigation provides a comprehensive set of fixed-system shears and moments, blade moment, and blade flap and lag response. The data set is well suited for use in the correlation and development of advanced rotorcraft analyses.

Image-Guided Robot-Assisted Techniques with Applications in Minimally Invasive Therapy and Cell Biology

There are several situations where tasks can be performed better robotically rather than manually. Among these are situations (a) where high accuracy and robustness are required, (b) where difficult or hazardous working conditions exist, and (c) where very large or very small motions or forces are involved. Recent advances in technology have resulted in smaller size robots with higher accuracy and reliability. As a result, robotics is finding more and more applications in Biomedical Engineering. Medical Robotics and Cell Micro-Manipulation are two of these applications involving interaction with delicate living organs at very different scales. Availability of a wide range of imaging modalities from ultrasound and Xray fluoroscopy to high magnification optical microscopes, makes it possible to use imaging as a powerful means to guide and control robot manipulators. This thesis includes three parts focusing on three applications of Image-Guided Robotics in biomedical engineering, including: • Vascular Catheterization: a robotic system was developed to insert a catheter through the vasculature and guide it to a desired point via visual servoing. The system provides shared control with the operator to perform a task semi-automatically or through master-slave control. The system provides control of a catheter tip with high accuracy while reducing X-ray exposure to the clinicians and providing a more ergonomic situation for the cardiologists. • Cardiac Catheterization: a master-slave robotic system was developed to perform accurate control of a steerable catheter to touch and ablate faulty regions on the inner walls of a beating heart in order to treat arrhythmia. The system facilitates touching and making contact with a target point in a beating heart chamber through master-slave control with coordinated visual feedback. • Live Neuron Micro-Manipulation: a microscope image-guided robotic system was developed to provide shared control over multiple micro-
HELAS IT-platform: A new tool for the European Helio- and Asteroseismology community.

HELAS is a Coordination Action funded under the European Commission’s Sixth Framework Programme (FP6) since April 1st, 2006 till March 31st, 2010. The HELAS Consortium includes 10 partner institutions that host researchers active in helioand asteroseismology. This initiative offers a unique chance to advance the field further by coordinating the activities of researchers, enhancing the quality and quantity of science performed in Europe. The HELAS Forum is one of its Networking Activities. Its main goal is to encourage, provide, and support the tools, activities, and initiatives emanating from the European helioand asterosesimology scientific communities. Thus, the HELAS Forum should ensure European competence and competitiveness in these areas by better coordinating the groups. It also enhances the synergies between the helioand astero communities and between those and other non-European related activities. Here, we present the Helas Forum IT-platform (www.helas-eu.org), developed to facilitate the coordinated activities such as data and software package exchange, information about workshops and meetings, knowledge of the community, etc., as well as to allow tracking the development of HELAS activities.

Design and Mechanical Properties Analysis of Radially Graded Porous Scaffolds

： A design method based on Gyroid surface is proposed to build radially graded porous scaffolds. Radially graded porous scaffolds with the same average porosity and different porosity change rate are designed by adjusting central porosity P in , marginal porosity P out and gradient change rate n . The mechanical properties of radially graded porous scaffolds and homogeneous porous scaffolds are studied by finite element method (FEM) analysis and mechanical experiment, and their differences are compared. The results of FEM analysis show that the mechanical properties of the radially graded porous scaffolds are better than those of the homogeneous porous scaffolds with the same average porosity. The higher the average porosity is, the better the mechanical properties of radially graded porous scaffolds are. The results of mechanical experiments show that when the average porosity is 70%, the elastic modulus and compressive strength of radially graded porous scaffolds are (2.34±0.05)GPa and (67.63±1.33)MPa, respectively. The elastic modulus and compressive strength of radially graded porous scaffolds are (3.96±0.19)GPa and (90.83±3.35)MPa, respectively. The FEM analysis and mechanical experiment show that the radially graded porous scaffolds have better performances than the homogeneous porous scaffolds.
