113th Annual ASEE Conference and Exposition, 2006

作者： Zoltowski, Carla Oakes, William Myers, Barrett Purdue University United States EPICS Program Purdue University United States ASEE Department of Engineering Education Purdue University United States EPICS Program Computer Programming Technology

There are many benefits to participating in multi-campus collaborations among project-based design teams. First, students gain experience in working in a distributed design environment, which is becoming more commonplace in engineering practice. Second, collaborations offer the ability to share complementary expertise and allow student design teams to participate in projects that they would not normally be able to undertake alone. Third, collaboration among teams of multiple campuses allows for sharing of prior work and the opportunity to build upon the work to have a more significant impact. There are, however, challenges to participating in multi-campus collaborations. It is difficult for student teams to partition projects such that they can be done somewhat independently. Communication issues can be complicated by distance and the lack of face-to-face contact on a regular basis. The EPICS - engineering Projects in Community Service - program engages undergraduate student design teams on long-term projects that solve technology-based problems for local community service organizations. There are sixteen universities with active EPICS programs in the 2005-2006 academic year. While the programs have some variation as EPICS has been integrated into each individual campus, they share basic characteristics. The existence of EPICS programs on multiple campuses has created the opportunity to collaborate across institutions. This paper will describe three models for multi-campus collaboration that have been used in EPICS. © American Society for engineering Education, 2006.

Explorative research is a vital part of biological sciences. Biologists frequently have to examine and compare multiple (large) sets of biological data in an interactive and explorative manner. Exploring alternative ways of examining the data and managing the necessary resources often require substantial (manual) effort and time. In this paper, we present a concrete example of how VLAM, a grid-based workflow management system, can enhance experimentation. We discuss in detail the process of developing the SigWin-detector, an application in the domain of bioinformatics. We show that SigWin-detector can promptly identify regions of increased gene expression in transcriptome maps and periodicity in weather data. We also show that the workflow can be extended or partially modified. The individual modules can also be used to compose different experiments. SigWin-detector fulfills the requirements of interactive and explorative experimentation. ©2006 IEEE.

In this paper the improvement in the performance obtained by a Time Interleaving applied to DVB-T scheme are analyzed in impulsive noise environments. The performance is evaluated in terms of bit error rate probability for 0ms, 100ms and 200ms of time interleaving length. The results are compared with the standard DVB-T (Digital Video Broadcasting - Terrestrial) evaluated on Impulsive Noise channel and Multipath combined with impulsive noise channel. Simulation results shows that employing Time Interleaving only with 100ms the overall system performance can improve significantly. These results are obtained applying an appropriate interleaving after the Mapper of DVB-T system. © 2006 IEEE.

Novices face many barriers when learning to program, including the need to learn both a new syntax and a model of computation. By constraining syntax and providing concrete visual representations on which to operate, direct manipulation programming environments can potentially lower these barriers. However, what if the learning goal of the novice is to be able ultimately to program in conventional textual languages, as is the case for introductory computer science students? Can direct manipulation programming environments lower the barriers to programming, and, at the same time, promote positive transfer to textual programming? To address this question, we designed a new direct manipulation programming interface for ALVIS Live!, a novice programming environment. We then conducted an experimental study that compared the programming outcomes promoted by the new direct manipulation interface to those promoted by ALVIS Live!'s textual programming interface. We found that the direct manipulation interface not only led to significantly better initial programming outcomes, but also to significant positive transfer to the textual interface. Our results show that direct manipulation interfaces can provide novices with a "way in" to traditional textual programming

This work presents the performance of WLAN and MANET networks using the auto-configuration of Mobile IP Agents Protocol (DRMIPA). This scheme would allow groups of MIP nodes in WLANs or MANETs to enjoy IP mobility at any foreign or local network that doesn't implement MIP. To maintain a failure free MIP network, a passive agent is elected from an active agent if this active agent leaves or ceases its participation from current network. The DRMIPA protocol is implemented in WLAN and MANET. A performance analysis is done using a real world testbed scenario.

Cyber theft is a serious threat to Internet security. It is one of the major security concerns by both network service providers and Internet users. Though sensitive information can be encrypted when stored in non-volatile memory such as hard disks, for many e-commerce and network applications, sensitive information is often stored as plaintext in main memory. Documented and reported exploits facilitate an adversary stealing sensitive information from an application's memory. These exploits include illegitimate memory scan, information theft oriented buffer overflow, invalid pointer manipulation, integer overflow, password stealing Trojans and so forth. Today's computing system and its hardware cannot address these exploits effectively in a coherent way. This paper presents a unified and lightweight solution, called InfoShield that can strengthen application protection against theft of sensitive information such as passwords, encryption keys, and other private data with a minimal performance impact. Unlike prior whole memory encryption and information flow based efforts, InfoShield protects the usage of information. InfoShield ensures that sensitive data are used only as defined by application semantics, preventing misuse of information. Comparing with prior art, InfoShield handles a broader range of information theft scenarios in a unified framework with less overhead. Evaluation using popular network client-server applications shows that InfoShield is sound for practical use and incurs little performance loss because InfoShield only protects absolute, critical sensitive information. Based on the profiling results, only 0.3% of memory accesses and 0.2% of executed codes are affected by InfoShield.

The algorithm of the dynamic control functions achieves a complex modeling regarding the behavior of any mechanical robot structure. First of all, considering the kinetic links dominated of stiffness hypothesis, on the basis of the new formulations with matrix exponentials, in this paper, the differentials expressions answerable to the forward kinematics of mechanical robot structures were presented. On the basis of these equations, in the following, the generalized dynamics forces were also analyzed for the robots with rigid and elastic structure

Haskell'05 - ACM SIGPLAN 2005 Haskell Workshop

作者： Stewart, Don Chakravarty, Manuel M. T. Programming Languages and Systems School of Computer Science and Engineering University of New South Wales

ISBN: (纸本)159593071X

Some Lisp programs such as Emacs, but also the Linux kernel (when fully modularised) are mostly dynamic;i.e., apart from a small static core, the significant functionality is dynamically loaded. In this paper, we explore fully dynamic applications in Haskell where the static core is minimal and code is hot swappable. We demonstrate the feasibility of this architecture by two applications: Yi, an extensible editor, and Lambdabot, a plugin-based IRC robot. Benefits of the approach include hot swappable code and sophisticated application configuration and extension via embedded DSLs. We illustrate both benefits in detail at the example of a novel embedded DSL for editor interfaces. Copyright © 2005 ACM.
