The Washington University in St. Louis IEEE student branch are designing a next-generation LED dance floor that synthesizes color, music, and touch in a way that has not been done in any other device. The device is being designed with modularity and expandability as key features and therefore a solid, reliable power system was needed. This report focuses on the project’s power distribution and ...

This paper addresses the problem of calibrating a pinhole camera from images of a surface of revolution. Camera calibration is the process of determining the intrinsic or internal parameters (i.e., aspect ratio, focal length and principal point) of a camera, and it is important for both motion estimation and metric reconstruction of 3D models. In this paper a novel and simple calibration techni...

We address the determination of the second point-to-point shortest simple path in undirected networks. The effective reduced cost concept is introduced to compute the second best solution. This concept is used to prove that a path tree containing the second point-to-point shortest simple path is adjacent to any shortest path tree. Therefore, this result immediately implies a methods requiring O...

In this paper we present a methodology for the evaluation of networked systems communicating using WLAN technology. We show a case study of goal-oriented cooperating robots, for which our approach is particularly useful. Developing robots is expensive; hence emulation can be employed in the first part of the development cycle to study robot software implementations in realistic conditions at a ...

The Input Validation Testing (IVT) technique has been developed to address the problem of statically analyzing input command syntax as de ned in English textual interface and requirements speci cations and then generating test cases for input validation testing. The technique does not require design or code, so it can be applied early in the lifecycle. A proof-of-concept tool has been implement...

This study presented an improved algorithm for solving large scale LAP. A preprocessing (PP) algorithm was proposed...

The knowledge of how to exactly deploy a wireless multi-hop network can be of interest for both researchers and engineers. Engineers may be interested in the possibility of extending the coverage area of their traditional access point and to provide ubiquitous Internet connectivity at a significantly reduced cost and some communities have already started to do so [1]–[3]. Researchers need large...

This paper describes the results obtained from the merging of two techniques that provide improvements to search and retrieval using Latent Semantic Indexing (LSI): Essential Dimensions of LSI (EDLSI) and partial singular value decomposition (PSVD) updating. EDLSI utilizes an implementation of LSI that requires the use of only a few dimensions in the LSI space. The PSVD updating and folding-up ...

In the near future, there is potential for a tremendous expansion in the number of Earth-orbiting CubeSats, due to reduced cost associated with platform standardization, availability of standardized parts for CubeSats, and reduced launching costs due to improved packaging methods and lower cost launchers. However, software algorithms capable of efficiently coordinating CubeSats have not kept up...
