A vibrotactile approach to tactile rendering
Authors: Dennis Allerkamp, Guido B&#x00f6;ttcher, Franz-Erich Wolter, Alan C. Brady, Jianguo Qu, Ian R. Summers
Venue: The Visual Computer: International Journal of Computer Graphics (2007)

While moving our fingertip over a fine surface we experience a sensation that gives us an idea of its properties. A satisfactory simulation of this feeling is still an unsolved problem. In this paper, we describe a rendering strategy based on vibrations that play an important role in the tactile exploration of fine surfaces. To produce appropriate excitation patterns we use an array of vibrating contactor pins. Similar to the colour model in computer graphics, we simulate arbitrary vibrations as a superposition of only two sinewaves. Each sinewave is intended for the excitation of a specific population of mechanoreceptors. We carried out first tests of our rendering strategy on Brownian surfaces of different fractal dimensions.
A construction method for optimally universal hash families and its consequences for the existence of RBIBDs
Authors: Philipp Woelfel
Venue: Theoretical Computer Science (2006)

We introduce a method for constructing optimally universal hash families and equivalently RBIBDs. As a consequence of our construction we obtain minimal optimally universal hash families, if the cardinalities of the universe and the range are powers of the same prime. A corollary of this result is that the necessary conditions for the existence of an RBIBD with parameters v, k, λ, namely v ≡ 0 (mod k) and λ(v - 1) ≡ 0(mod k - 1), are sufficient, if v and k are powers of the same prime. As an application of our construction, we show that the k-MAXCUT algorithm of Hofmeister and Lefmann [A combinatorial design approach to MAXCUT, Random Struct. Algorithms 9 (1996) 163-173] can be implemented such that it has a polynomial running time, in the case that the number of vertices and k are powers of the same prime.

Towards a language for the description of IC chips: (part II)
Authors: Reiner W. Hartenstein
Venue: ACM SIGMICRO Newsletter (1973)

This paper is continuing as "part II" a paper out of the preceding number of SIGMICRO Newsletter. That preceding paper (for its title see ref. |10|) is referenced as "part I" in the following lines. (As in part I |10|, also in part II some of the ideas are half-baked ideas.) In part I a draft design has been given of a set of register transfer primitives (RTP) and a corresponding symbolic notation, as well as its block diagramm equivalent. Part I particularly aimed at the demonstration of the use of register transfer notations for modelling constructs known from the software field, as seen with the eyes of a hardware man.
Studying vehicle movements on highways and their impact on ad-hoc connectivity
Authors: Holger Füßler, Marc Torrent-Moreno, Matthias Transier, Roland Krüger, Hannes Hartenstein, Wolfgang Effelsberg
Venue: ACM SIGMOBILE Mobile Computing and Communications Review (2006)

The mobility of the nodes in a Mobile Ad-Hoc Network (MANET) is a crucial factor in the performance studies of communication protocols for these kind of networks. For this reason, researchers usually use a randomized node movement model, such as the Random Way-Point Model [6], in the process of designing or analyzing the behavior of their protocols. Since movement is not very predictable in these scenarios, they generally serve as a "worst case assumption" of node mobility concerning communication protocol performance in the sense that a positive correlation between performance in an RWP scenario and an arbitrary scenario exists. Additionally, RWP is an analytically well-understood mobility scheme and the movements can be generated very easily with tools complementary to most of the common network simulators.
Using performance signatures and software rejuvenation for worm mitigation in tactical MANETs
Authors: Alberto Avritzer, Robert G. Cole, Elaine J. Weyuker
Venue: Proceedings of the 6th international workshop on Software and performance (2007)

In this paper, we propose a new approach for mitigation of worm propagation through tactical Mobile Ad-Hoc Networks (MANETs) which is based upon performance signatures and software rejuvenation. Three application performance signature and software rejuvenation algorithms are proposed and analyzed. These algorithms monitor critical applications' responsiveness and trigger actions for software rejuvenation when host resources degrade due to a co-resident worm competing for host resources. We analyze the effectiveness of our algorithms through analytic modeling and detailed, extensive simulation studies. The key performance metrics investigated are application response time, mean time between rejuvenations and the steady state probability of host infection. We also use simulation models to investigate several design and parameter tuning issues. We investigate the relationship between the rate at which the application performance monitors can detect out-of-specification applications and the rate of worm propagation in the network.
Notes from journals
Authors: Stanley Habib
Venue: ACM SIGMICRO Newsletter (1975)

Incorporating user-oriented features usually found only in much larger computers, the first models of the Eclipse line, the $100 and $200, use a high speed micro-programmed central processor, and can run with either; core or semiconductor memories, or both. The core and semiconductor memories are available with an error detection and correction feature that can find and correct; single bit errors caused by the computer. The semiconductor memories use a high-speed cache to increase memory speed. The Eclipse $100, the smaller of the two computers, will be used by oems or by end users who need a smaller system to meet their requirements. The Eclipse $100 is 5-1/4 inches high, and holds six standard Data General printed circuit boards. It costs $9200, with 16k bytes of core memory, and $10,700 with 16k bytes of semiconductor memory. Eclipse $100 deliveries will begin in December. The Eclipse $200, a system-oriented computer that can hold 16 printed circuit boards, will be used by system builders or end users who will build large scale computing systems around it. The Eclipse $200 is 10-1/2 inches high, and costs $16,300 with 32k bytes of core memory, and $19,300 with 32k bytes of semiconductor memory. Deliveries of the Eclipse $200 will begin in February. The instruction set of both Eclipse computers is microprogrammed in the central processor. There are over 40 new instruction in the Eclipse computers. Programs written on Nova computers will run on either the Eclipse $100 or $200. The central processor includes a Writeable Control Store making up to 256, 56-bit words available to write specialized micro-programmed instructions. The instruction set is enhanced to help programmers writing in assembly language or high-level language programs. Hardware memory stacks, supported by comprehensive instructions, make programming more efficient, while block, word, byte and bit manipulation instructions improve system performance. Instructions are both single word and double word instructions.

Discovering Interesting Relationships among Deep Web Databases: A Source-Biased Approach
Authors: James Caverlee, Ling Liu, Daniel Rocco
Venue: World Wide Web (2006)

The escalation of deep web databases has been phenomenal over the last decade, spawning a growing interest in automated discovery of interesting relationships among available deep web databases. Unlike the "surface" web of static pages, these deep web databases provide data through a web-based query interface and account for a huge portion of all web content. This paper presents a novel source-biased approach to efficiently discover interesting relationships among web-enabled databases on the deep web. Our approach supports a relationship-centric view over a collection of deep web databases through source-biased database analysis and exploration. Our source-biased approach has three unique features: First, we develop source-biased probing techniques, which allow us to determine in very few interactions whether a target database is relevant to the source database by probing the target with very precise probes. Second, we introduce source-biased relevance metrics to evaluate the relevance of deep web databases discovered, to identify interesting types of source-biased relationships for a collection of deep web databases, and to rank them accordingly. The source-biased relationships discovered not only present value-added metadata for each deep web database but can also provide direct support for personalized relationship-centric queries. Third, but not least, we also develop a performance optimization using source-biased probing with focal terms to further improve the effectiveness of the basic source-biased model. A prototype system is designed for crawling, probing, and supporting relationship-centric queries over deep web databases using the source-biased approach. Our experiments evaluate the effectiveness of the proposed source-biased analysis and discovery model, showing that the source-biased approach outperforms query-biased probing and unbiased probing.
An Eclipse microassembler
Authors: Daniel Martin
Venue: ACM SIGMICRO Newsletter (1977)

The microprogrammed Data General Eclipse S/200 computer is available with a writable control store (WCS). The WCS feature of the Eclipse is an extension of the microprogrammed control logic of the computer's central processing unit. It allows a user to implement specialized instructions at a very low level. Its use is however, discouraged since Data General does not provide software support for the WCS feature. A microassembler was written to alleviate this problem on the Memphis State System.
Embedded Image Coding Using Context Adaptive Wavelet Difference Reduction
Authors: Poonlap Lamsrichan, Teerapat Sanguankotchakorn
Venue: IEICE - Transactions on Information and Systems (2007)

It is well-known that one of the best wavelet-based image compression techniques, called Wavelet Difference Reduction--WDR, has both simple algorithm and comparative rate-distortion results comparing to other coders in the literature. In this paper, we propose an algorithm to enhance the performance of WDR coder in a very efficient way. The methodology is highly based on the context adaptive model. High-order statistical context modeling is used for significant coefficients prediction by scanning order adaptation of WDR. In binary mode, the coder is clearly better than Set Partitioning in Hierarchical Trees (SPIHT). A new conditional Arithmetic Coding (AC) using array of contexts is specifically designed for WDR-based coder. Based on our simulation results of all images in the test set which covers various types of images, it is apparent that our proposed coder in AC mode generates the rate-distortion results that are superior to those of all other WDR-based coders in the literature. Furthermore, it is very competitive to SPIHT-AC and JPEG2000, the best coders, at all bit rates.
The lonesome cowboy: A study of the usability designer role in systems development
Authors: Inger Boivie, Jan Gulliksen, Bengt Göransson
Venue: Interacting with Computers (2006)

This paper reports on an evaluation of the usability designer role as applied in two Swedish systems development organisations. The role was initially defined by us, but evolved in these two organisations. We conducted interviews with usability designers, project managers and a user representative. Our main research question was whether or not the introduction of a usability designer has been successful in terms of changes in the systems development process and the impact the role has had on products, projects and organisations. To some extent, the role has met our expectations and intentions for instance, in helping the usability designers shift their focus towards design, and assume some kind of ''users' advocate'' role. But in other ways, the role ''failed''. The usability designers in our study are still facing the kind of problems and obstacles that usability professionals have always had to deal with.
Bash Cookbook: Solutions and Examples for Bash Users (Cookbooks (O'Reilly))
Authors: Cameron Newham, J. Vossen, Carl Albing, Jp Vossen
Venue:  (2007)

The key to mastering any Unix system, especially Linux and Mac OS X, is a thorough knowledge of shell scripting. Scripting is a way to harness and customize the power of any Unix system, and it's an essential skill for any Unix users, including system administrators and professional OS X developers. But beneath this simple promise lies a treacherous ocean of variations in Unix commands and standards. bash Cookbook teaches shell scripting the way Unix masters practice the craft. It presents a variety of recipes and tricks for all levels of shell programmers so that anyone can become a proficient user of the most common Unix shell -- the bash shell -- and cygwin or other popular Unix emulation packages. Packed full of useful scripts, along with examples that explain how to create better scripts, this new cookbook gives professionals and power users everything they need to automate routine tasks and enable them to truly manage their systems -- rather than have their systems manage them.
Factor-analysis based anomaly detection and clustering
Authors: Ningning Wu, Jing Zhang
Venue: Decision Support Systems (2006)

This paper presents a novel anomaly detection and clustering algorithm for the network intrusion detection based on factor analysis and Mahalanobis distance. Factor analysis is used to uncover the latent structure of a set of variables. The Mahalanobis distance is used to determine the "similarity" of a set of values from an "unknown" sample to a set of values measured from a collection of "known" samples. By utilizing factor analysis and Mahalanobis distance, we developed an algorithm 1) to identify outliers based on a trained model, and 2) to cluster attacks by abnormal features.

Venue: Soft Computing - A Fusion of Foundations, Methodologies and Applications (2007)

From the ordinal sum theorem for t-subnorms, Jenei introduced a new left-continuous t-norm (called RDP t-norm) by revising the drastic product t-norm. In this paper, propositional and predicate calculi generated by RDP t-norm and its residuum are introduced and the corresponding formal systems RDP and RDP&#x2200;, which are schematic extensions of Esteva and Godo&#x2019;s MTL and MTL&#x2200;, respectively, are presented and the standard completeness for RDP and RDP&#x2200; are proved. In addition, a new formula defining the standard disjunctive in RDP was given
