Creating geo-specific road databases from aerial photos for driving simulation

WSEAS Transactions on computers 2007年第6期6卷 871-879页

Geo-specific road databases are sometimes necessary for driving simulation studies. However, manually creating them is very time consuming. One of the reasons is that a real road can have non-uniform cross sections due to irregular shaped road boundaries. Additionally, in the UCF (University of Central Florida) driving simulator system, the road database format requires identification of repeatable cross sections, also a labor intensive process. Even though some commercial software applications, such as the MultiGen Road Tool have road modeling functions, roads with non-uniform cross-sectional profiles are still hard to model.

This paper reports on the very impressive outcome of a project designed and built by a group of engineering students. The project was dubbed Project G (short for Godzilla). The students were all undergraduate students, from various graduating classes and mostly from all five of our engineering departments. Their teamwork and their problem-solving skills were very exemplary throughout the project duration. Furthermore, the students accomplished their task from beginning to end without any faculty supervision. An impressive accomplishment which, for us faculty, is interpreted as a testimony that we must, after all, be doing something right in class. Or so we hope at least. Project G consists basically of a large Lego-built dragon that can move around, and spit fire. The intricacy in its details is a result of the countless hours that the students worked on it and the engineering problem solving skills that they demonstrated. Every step was documented and pictures and videos were recorded, a testimony to the high commitment to teamwork from this group of students who come from a wide variety of disciplines. We describe project G in an informal manner, and all the steps and solutions along the way of its creation. We demonstrate that with proper preparation, a good selection of courses, a high commitment to teaching and learning, a university can educate its engineering students to solve, without supervision, a very difficult problem that they (and we) can be very proud of. We suggest in conclusion that though project G in its current form would not yet be suitable for a senior design capstone project, it would be a very good example for a multi-disciplinary engineering design project. © American Society for engineering Education, 2007.

The purpose of the proposed study was to provide a solution to the Wisconsin Diagnostic Breast Cancer (WDBC) classification problem. The WDBC dataset, provided by the University of Wisconsin Hospital, was derived from a group of images using Fine Needle Aspiration (biopsies) of the breast. An ensemble of Support Vector Machines (SVM's) was employed in this study. Support vectors with linear, polynomial and RBF kernel functions were trained using a fraction of the WDBC dataset as a training set. The five top performing models were recruited into the ensemble. The classification was then carried out using the majority opinion of the ensemble. The SVM ensemble successfully classified more than 99 percent of the testing data and in the process yielded 100 percent benign tumor prediction accuracy. © 2007 IEEE.

Intrusion detection is the process of monitoring the events occurring in a computer system or network and analyzing them for signs of intrusions, defined as attempts to compromise the confidentiality, integrity, availability, or to bypass the security mechanisms of a computer or net-work. This paper proposes the development of an Intrusion Detection program (IDP) which could detect known attack patterns. An IDP does not eliminate the use of any preventive mechanism but it works as the last defensive mechanism in securing the system. Three variants of genetic programming techniques namely Linear Ge-netic programming (LGP), Multi-Expression programming (MEP) and Gene Expression programming (GEP) were evaluated to design IDP. Several indices are used for comparisons and a detailed analysis of MEP technique is provided. Empirical results reveal that genetic programming technique could play a major role in developing IDP, which are light weight and accurate when compared to some of the conventional intrusion detection systems based on machine learning paradigms.

We describe recruitment and selection procedures of the computer science, engineering, and Mathematics Scholarship (CSEMS) program at the University of Wisconsin-Milwaukee that are designed to attract students who are academically talented, financially needy, and diverse. In particular, we address the possible exclusion of underrepresented minority students that could result if standardized test scores are used indiscriminately as metrics of student performance in both recruitment and selection procedures. We describe a "conditional award" process that enables students whose calculus placement is moderately below calculus to competitively apply for and receive scholarships;awards to such students are activated on the condition that they attempt to attain calculus placement prior to matriculation. We present data that demonstrate moderate effectiveness of these methods in fostering diversity among our scholars and reasonably encouraging retention and estimated graduation rates. We discuss areas of improvement for future program years, such as forging new partnerships with local Project Lead The Way high schools to recruit higher numbers of females and minorities, and developing new mentoring opportunities to reduce attrition, especially among underrepresented minority students. © American Society for engineering Education, 2007.

Diversity preservation has already been established as an important concern for evolutionary computation. Clustering techniques were, among others, successfully applied to this purpose. Another important aspect of the research on evolutionary computation is related to linkage learning - the detection of the problem structure avoiding disruption of building blocks when new individuals are generated. This paper presents a novel approach which is a new estimation of distribution algorithm (EDA) where clustering plays two roles: diversity preservation and linkage learning. Initial empirical investigations illustrate the behavior of the algorithm when solving two benchmark optimization problems. © 2007 IEEE.

This paper introduces an on-going research for developing a dynamic path planning system to improve mobile robot navigation in a dynamic building construction site by integrating a set of sensor-equipped robots into a real-time indoor positioning system. In the proposed navigation system, the communication between mobile robot, an ultrawideband (UWB) position system, and a portable computer is implemented over a wireless LAN. The location data from the UWB sensor network enables accurate visual representation of the mobile robot to be displayed in a 3D CAD drawing in a real-time manner. The tested positional accuracy of the wireless configuration of the current UWB system is about 36 cm. The key advantages of the proposed approach are: (1) this approach is fully untethered self-powered wireless system with real time data delivery, and (2) the developed position tracking and robot control software modules can be easily imbedded into standard CAD programs, thus reducing computational burden on developing a new graphical user interface (GUI) for different building applications. © 2007 American Society of Civil Engineers.

Anisotropic fluorocarbon plasma etching of Si/SiGe heterostruetures

引用

Journal of Vacuum science and Technology B: Microelectronics and Nanometer Structures 2007年第2期25卷 404-409页

作者： Ding, R. Klein, L.J. Eriksson, M.A. Wendt, A.E. Materials Science Program University of Wisconsin-Madison Madison WI 53706 Department of Physics University of Wisconsin-Madison Madison WI 53706 Department of Electrical and Computer Engineering University of Wisconsin-Madison Madison WI 53706

Fluorocarbon plasma etching of Si/SiGe heterostructures is demonstrated as a method for fabrication of quantum devices with vertical sidewalls. The heterostructures consist of layers of Si and SiGe, and anisotropic etching of the heterostructures using plasmas to isolate device elements is an attractive approach to fabricating devices. A challenge that has limited the use of fluorocarbon etching is the difference in Si and SiGe etch rates under comparative conditions. Preferential etching of SiGe can lead to undercutting beneath the top Si layer, causing a reduction in critical device dimensions of unknown magnitude. By using fluorocarbon etch gases with high carbon content, fluorocarbon sidewall passivation improves the anisotropy of etched feature profiles by preventing lateral etching of SiGe. Etch results with a C 4F8/Ar/N2 gas mixture show a straight sidewall profile through the layers of the heterostructure. © 2007 American Vacuum Society.

The concept of having first-year students conduct 'One Minute Engineer' (OME) presentations was presented at the 2006 ASEE National Conference1. OME presentations, first developed at Northeastern University (NU), consist of having students individually provide a short (nominally one minute) presentation on an engineering-related topic at the beginning of class each day, with each student participating once during the term. Students select the topics in advance on a first-come, first-serve basis, with feedback from the instructor on the chosen topic. Instructors could then relate future lectures and concepts to earlier student presentations. The 2006 ASEE paper presented results from two instructors at two different universities. The data showed that students reported an increased awareness of engineering topics as a result of the One-Minute Engineer. Since this method showed similar - and promising - outcomes at two different institutions, the authors agreed to implement the OME activity across all sections of the first engineering course at Ohio Northern University (ONU). Pre- and post- surveys similar to those administered in the original OME implementation were used at this institution. These results were compared to the previously published data as well as with the current class at the originating institution. An additional level of assessment was added to this iteration of the OME through the establishment of a rubric for evaluating the students' presentation skills. Finally, assessment data on students' engineering awareness was compared across universities. © American Society for engineering Education, 2007.
