Introduction to Convolutional Codes with Applications
Authors: Ajay Dholakia
Venue:  (1994)

:Convolutional codes have been extensively used in practical error control applications on a variety of communication channels. Introduction to Convolutional Codes with Applications provides an introduction to the basic concepts of convolutional codes, their structure and classification, various error correction and decoding techniques for convolutionally encoded data, and some of the most common applications. The definition and representations, distance properties, and important classes of convolutional codes are also discussed in detail. Introduction to Convolutional Codes with Applications provides the first comprehensive description of table-driven correction and decoding of convolutionally encoded data. Complete examples of Viterbi, sequential, and majority-logic decoding technique are also included, allowing a quick comparison among the different decoding approaches. Introduction to Convolutional Codes with Applications summarizes the research of the last two decades on applications of convolutional codes in hybrid ARQ protocols. A new classification of hybrid ARQ protocols based on fixed or variable amount of coding redundancy is suggested. This classification allows a natural way of studying the underlying concepts of hybrid ARQ schemes and accommodates all of the new research in this area. A novel application of fast decodable invertible convolutional codes for lost packet recovery in high speed networks is described. This opens the door for using convolutional coding for error recovery in high speed networks. Practicing communications, electronics and networking engineers who want to get a better grasp of the underlying concepts of convolutional coding and its applications will greatly benefit by the simple and concise style of explanation. As a reference, an up-to-date bibliography of over 300 papers is included. Introduction to Convolutional Codes with Applications is also suitable for use as a textbook or a reference text in an advanced course on co
Short-Range Wireless Communication: Fundamentals of RF System Design and Application with Cdrom
Authors: Alan Bensky
Venue:  (2000)

:The expansion of wireless communication in the last 5 to 10 years has been astounding. It is most visible in telecommunications products and services such as cellular telephones, portable telephones, direct broadcast satellite transmissions, and pagers. However, another aspect of the wireless revolution, also forging its path to the future, is the field of short-range radio frequency (RF) communication. We can see its influence in security systems, computer accessories such as the untethered mouse, home automation, emergency call buttons for the sick and elderly, wireless local area networks (WLAN), and radio frequency identification. These applications can be distinguished from the telecommunication services by their short range, typically only up to several hundred meters. Exciting new technologies are coming to fruition right now, the two most promising coming from the 'Bluetooth' standard and the SWAP (Shared Wireless Access Protocol)--with both of these, consortiums of major electronics and communications companies are working to develop wireless digital communication between personal computers, peripherals, and consumer electronic devices around the home and office, using short-range RF. There are virtually no technical books devoted to short-range radio and there is beginning to be a huge need for more published information. This book was written to give a basic but comprehensive understanding of radio communication to a wide base of technically oriented readers who either have a curiosity to know how wireless works, or who will contribute to expanding its uses.

Quasi-Monte Carlo methods in cash flow testing simulations
Authors: Michael G. Hilgers
Venue: Proceedings of the 32nd conference on Winter simulation (2000)

What actuaries call cash flow testing is a large-scale simulation pitting a company's current policy obligation against future earnings based on interest rates. While life contingency issues associated with contract payoff are a mainstay of the actuarial sciences, modeling the random fluctuations of US Treasury rates is less studied. Furthermore, applying standard simulation techniques, such as the Monte Carlo method, to actual multi-billion dollar companies produce a simulation that can be computationally prohibitive. In practice, only hundreds of sample paths can be considered, not the usual hundreds of thousands one might expect for a simulation of this complexity. Hence, insurance companies have a desire to accelerate the convergence of the estimation procedure. This paper reports the results of cash flow testing simulations performed for Conseco L.L.C. using so-called quasi-Monte Carlo techniques. In these, pseudo-random number generation is replaced with deterministic low discrepancy sequences. It was found that by judicious choice of subsequences, the quasi-Monte Carlo method provided a consistently tighter estimate, than the traditional methods, for a fixed, small number of sample paths. The techniques used to select these subsequences are discussed.

The context fabric: an infrastructure for context-aware computing
Authors: Jason I. Hong
Venue: CHI '02 extended abstracts on Human factors in computing systems (2002)

Despite many sensor, hardware, networking, and software advances, it is still quite difficult to build effective and reliable context-aware applications. We propose to build a context infrastructure that provides three things to simplify the task of building context-aware applications: a context data store for modeling, storing, and distributing context data; a context specification language for declaratively stating and processing context needs; and protection mechanisms for safeguarding privacy needs.
Ears and hair: what headsets will people wear?
Authors: Rebecca E. Grinter, Allison Woodruff
Venue: CHI '02 extended abstracts on Human factors in computing systems (2002)

Many different audio headsets are commercially available. To choose a headset for a short-term use environment, we conducted a pilot study to elicit end-user criteria for headsets. We discovered a number of severe end-user issues with less traditional designs, and concluded that a minor variant of a traditional design is more appropriate for our application than many of the more exotic options that have recently become available.
Interaction techniques for navigation through and manipulation of 2D and 3D data
Authors: Dzmitry Aliakseyeu, Sriram Subramanian, Jean-Bernard Martens, Matthias Rauterberg
Venue: Proceedings of the workshop on Virtual environments 2002 (2002)

In this article we present a working prototype incorporating some new interaction techniques for the navigation through and the manipulation of both 3D and 2D data. The prototype aims at professional applications like architectural design, surgical planning and geological exploration. Its design was influenced by the analysis of user requirements and by the requirement for a natural interface. The prototype permits the user to navigate through 3D and 2D data in order to explore the internal structure. 3D navigation is accomplished by means of a natural selection of dynamically updated cross-sections. The user can navigate through these selected cross-sections of 2D data and can perform manipulations with them. As a proof of concept we focus on two disciplines, viz. architectural design and surgical planning. Our usability evaluation of the interaction styles demonstrates that they are perceived as useful and enjoyable additions to existing techniques in these disciplines.

Stochastic wire length sampling for cycle time estimation
Authors: Muzammil Iqbal, Ahmed Sharkawy, Usman Hameed, Phillip Christie
Venue: Proceedings of the 2002 international workshop on System-level interconnect prediction (2002)

Cycle time models perform an a-priori calculation of local signal delays by estimating the lengths of wires connecting different levels of synchronously clocked logic elements. Typically, a signal will have to pass through approximately 15-25 layers of logic during a single clock cycle and it is has been assumed that this number is sufficiently large to allow average wire lengths to be used. This paper investigates the accuracy of this mean value assumption by comparing cycle times calculating using average wire lengths with cycle times calculated using wires sampled from an estimate of the wire length distribution in each wiring layer. The sampling algorithm provides a more accurate calculation of the cycle time and also an estimate of its variation due to the inherently stochastic nature of the layout process. Results for a benchmark netlist, implemented in 0.25 &mgr;m technology, indicate that for a logic depth of 25 the mean value assumption is satisfactory and that clock rate has a standard deviation of approximately 5% of this mean value due to the inherently stochastic nature of the layout process.

Table-driven problem solvers
Authors: David S. Burris, Kurt Schember
Venue: Proceedings of the 18th annual Southeast regional conference (1980)

This paper suggests an extension of decision tables and finite automata to more general table-driven problem solvers. The basic idea is that when a problem description is changed, only the contents table directing the flow of control and actions taken by a program need be modified and not the actual code. Program actions may be changed easily and documentation and program reliability improved.
The Inktomi climate lab: an integrated environment for analyzing and simulating customer network traffic
Authors: Stephane Gigandet, Ashok Sudarsanam, Anshu Aggarwal
Venue: Proceedings of the 1st ACM SIGCOMM Workshop on Internet Measurement (2001)

This paper describes the Inktomi Climate Lab, an in-house environment that analyzes and simulates the HTTP traffic at our customer deployments. This lab is used to verify the stability and measure the performance of our web proxy cache, Inktomi Traffic Server1, which has been deployed at many customer sites. The ability to support all HTTP headers, methods, and status codes, as well as features such as pipelining and chunked-encoding, enables our Climate Lab to accurately simulate any deployment.Having an in-house Climate Lab that is able to reproduce the network traffic at any customer site affords several benefits. For instance, it gives us the ability to thoroughly stress-test the software before deployment, thus ensuring its high quality and robustness in the field. Also, it gives us the ability to quickly reproduce and resolve software issues that do occur in the field.

Self-Organization in Vision: Stochastic Clustering for Image Segmentation, Perceptual Grouping, and Image Database Organization
Authors: Yoram Gdalyahu, Daphna Weinshall, Michael Werman
Venue: IEEE Transactions on Pattern Analysis and Machine Intelligence (2001)

We present a stochastic clustering algorithm which uses pairwise similarity of elements and show how it can be used to address various problems in computer vision, including the low-level image segmentation, mid-level perceptual grouping, and high-level image database organization. The clustering problem is viewed as a graph partitioning problem, where nodes represent data elements and the weights of the edges represent pairwise similarities. We generate samples of cuts in this graph, by using Karger's contraction algorithm (1996), and compute an "average" cut which provides the basis for our solution to the clustering problem. The stochastic nature of our method makes it robust against noise, including accidental edges and small spurious clusters. The complexity of our algorithm is very low: O(|E| log2 N) for N objects, |E| similarity relations, and a fixed accuracy level. In addition, and without additional computational cost, our algorithm provides a hierarchy of nested partitions. We demonstrate the superiority of our method for image segmentation on a few synthetic and real images, both B W and color. Our other examples include the concatenation of edges in a cluttered scene (perceptual grouping) and the organization of an image database for the purpose of multiview 3D object recognition
Application of FPGA technology to accelerate the finite-difference time-domain (FDTD) method
Authors: Ryan N. Schneider, Laurence E. Turner, Michal M. Okoniewski
Venue: Proceedings of the 2002 ACM/SIGDA tenth international symposium on Field-programmable gate arrays (2002)

The continuing advances in the field of electrical engineering, in areas like cellular communications, fiber optics, mobile and multi-gigahertz electronics have necessitated a computer-assisted design approach to the complex electromagnetic interactions and problems that arise. Finite-Difference Time-Domain (FDTD) Analysis is a very powerful tool for the modeling of electromagnetic phenomena. The algorithm is computationally intensive and simulations can run for a few hours to several days. Increasing the computation speed and decreasing the run times of this algorithm would bring greater productivity and new avenues of research to many facets of electrical engineering.The algorithm is transferred to custom FPGA-based hardware using a pipelined bit-serial arithmetic architecture. A one-dimensional resonator is used to verify the implementation and explore the hardware speed and costs. The computational speed is extremely fast and is not related to the number of computational cells in the simulation. Finally, a discussion of future research is presented.
