Faceted search with a large amount of properties. Exploring opportunities for faceted search for an e-commerce application with a large amount of dynamic properties

Qalixa.com is a online e-commerce meta search engine that consolidate articles from a growing number of retailers from most lines of retail business. The articles in store entail a variety of meta data types such as properties, tags, category structures and free text. In this project, the author try to find ways to exploit the meta data and facilities available through a modern Enterprise search solution to create suggestions on how to build a User interface with sufficient competence to deal with this complex search space in an empowering manner, yet represent a simple enough experience for the end user to allow overview as well as a simple as possible learning curve. A few concepts are prototyped and a variety of options of future work are analyzed. Characteristic issues with applying faceted search to the particular case are found and analyzed to some detail. Concepts that are tested to some extent are selectable facet filters, grouping of properties with clustering, fuzzy logic in facet search and implicit ordering of documents given filter order.

War nibbling: Bluetooth insecurity

A method for drilling boreholes utilizing a plurality of simultaneously operated boring tools. During a drilling operation the loading forces on the tools are measured and constantly compared with a predetermined limiting value representative of a limiting loading value and the variation of a limiting loading value with respect to time. If these limiting values are exceeded at least one working parameter of the tools is adjusted such as feed force, feed speed or track speed of the tools. Apparatus for carrying out the method is also disclosed.
Developing a Software Engineering Methodology for Knowledge-Based Systems.

Abstract : Current expert systems are typically difficult to change once these are built. This report describes a design methodology intended to make a knowledge-based system easier to change, particularly by people other than its original developer. The basic approach for solving this problem is to divide the information in a knowledge base and attempt to reduce the amount of information that each single knowledge engineer must understand before he can make a change to the knowledge base. The method thus divides the domain knowledge in an expert system into groups and then attempts to limit carefully and specify formally the flow of information between these groups to localize the effects of typical changes within the groups. Keywords: Rule based systems; Programming languages; Algorithms; Partitioning; Production systems.
Improving the Round Trip Time Estimation in Internet Routers

We review in this paper the concept of TCP-friendliness and we debate one of its weaknesses. Unfortunately, this weakness reduces the practical applicability of the TCP-friendliness equation. For a very high percent of the Internet flows, the TCP-friendliness test may have wrong re- sults. We suggest in this paper a router algorithm that improves the efficiency of the TCP-friendliness equation for some UDP flows. This algorithm uses the additional information retrieved by the router from competing TCP flows in order to obtain a better approximation for the round trip time as used in the TCP-friendliness test.

Un modèle multi-sources pour la segmentation en sujets de journaux radiophoniques

Nous présentons une méthode de segmentation de journaux radiophoniques en sujets, basée sur la prise en compte d’indices lexicaux, syntaxiques et acoustiques. Partant d’un modèle statistique existant de segmentation thématique, exploitant la notion de cohésion lexicale, nous étendons le formalisme pour y inclure des informations d’ordre syntaxique et acoustique. Les résultats expérimentaux montrent que le seul modèle de cohésion lexicale ne suffit pas pour le type de documents étudié en raison de la taille variable des segments et de l’absence d’un lien direct entre segment et thème. L’utilisation d’informations syntaxiques et acoustiques permet une amélioration substantielle de la segmentation obtenue.

Exchange Rates and Real Long-Term Interest-Rate Differentials: Evidence for Eighteen OECD Countries

The bivariate relationship between real exchange rates and the real long-term interest rate differential has been investigated in a number of recent studies. By exchange-rate-equation standards, this specification does a relatively good job of tracking the historical movements in the dollar-Deutschemark and the dollar-yen bilateral exchange rates, and the dollar effective exchange rate; but does a poor job for the dollar-sterling rate. This paper extends the analysis to 18 OECD countries, in bilateral as well as effective terms. Results from earlier studies are confirmed, but in general the estimation results are sufficiently mixed to suggest that the absence of any risk premia variables may be an important omission . La relation entre les deux variables, taux de change reels et variations du taux d'interet reel a long terme, a ete etudiee dans un certain nombre d'etudes recentes. Comparee aux equations sur les taux de change, cette specification permet de retracer assez valablement les mouvements dans le temps des taux de change bilateraux du dollar par rapport au deutschemark et du dollar par rapport au yen ; il en va toutefois differemment en ce qui concerne le taux du dollar par rapport a la livre sterling. Le present document elargit cette analyse en la faisant porter sur 18 pays membres de l'OCDE et prend en compte tant les taux de change bilateraux que les taux de change effectifs. Les resultats obtenus confirment les etudes anterieures, mais les estimations sont dans l'ensemble suffisamment erratiques pour suggerer que l'absence de toute variable de primes de risque constitue peut-etre une omission importante .
Signaling and Simulations in Sociolinguistics

Along with game theory, the emerging science of networks has given us a framework for analyzing social systems plausible to both intuition and implementation. As an interaction structure in computer simulation models, social networks provide a way to envision phenomena like information spread, dialect formation, and language change in a more robust way. In this sense a multitude of sociolinguistic issues are potential 'objects of study' for a) being delineated with methods from game theory and/or network theory and b) being analyzed by simulations of multi-agent interactions, with the goal of exploring the interplay between social factors and linguistic usage. In this sense we i) consider network structure as an important social variable; ii) depict the usage of computer simulations as an appropriate, valid, and powerful technique to analyze sociolinguistic issues; and iii) put a premium on game theory as a method for adequately modeling communicative behavior, with the conclusion that network theory & game theory in simulation models represents a powerful combination for the analysis of sociolinguistic phenomena. This makes it a crucial supplement towards enhancing current sociolinguistic experimentation and theories.

Geração de impressão digital para recuperação de documentos similares na web

This paper presents a mechanism for the generation of the “fingerprint” of a Web document. This mechanism is part of a system for detecting and retrieving documents from the Web with a similarity relation to a suspicious document. The process is composed of three stages: a) generation of a fingerprint of the suspicious document, b) gathering candidate documents from the Web and c) comparison of each candidate document and the suspicious document. In the first stage, the fingerprint of the suspicious document is used as its identification. The fingerprint is composed of representative sentences of the document. In the second stage, the sentences composing the fingerprint are used as queries submitted to a search engine. The documents identified by the URLs returned from the search engine are collected to form a set of similarity candidate documents. In the third stage, the candidate documents are “in-place” compared to the suspicious document. The focus of this work is on the generation of the fingerprint of the suspicious document. Experiments were performed using a collection of plagiarized documents constructed specially for this work. For the best fingerprint evaluated, on average 87.06% of the source documents used in the composition of the plagiarized document were retrieved from the Web. Resumo. Este artigo apresenta um mecanismo para geracao da “impressao digital” de um documento da Web. Esse mecanismo e parte de um sistema para detectar e recuperar documentos que tenham sido plagiados da Web, sendo similares a um dado documento suspeito. O processo e composto de tres etapas: a) geracao de uma impressao digital do documento suspeito, b) coleta de documentos candidatos da Web e c) comparacao entre cada documento candidato e o documento suspeito. Na primeira etapa, a impressao digital do documento suspeito e usada para identifica-lo. A impressao digital e constituida por um conjunto de frases mais representativas do documento. Na segunda etapa, as frases que constituem a impressao digital sao usadas como consultas e submetidas para uma maquina de busca. Os documentos identificados pelas URLs da resposta da pesquisa sao coletados e formam um conjunto de documentos candidatos a similaridade. Na terceira etapa, os documentos candidatos sao localmente comparados com o documento suspeito. O foco deste trabalho esta na geracao da impressao digital do documento plagiado. Experimentos foram realizados sobre uma colecao de documentos plagiados construida especialmente para este trabalho. Para a impressao digital de melhor resultado, em media 87, 06% dos documentos usados na composicao do documento plagiado foram recuperados da Web.
A Band Without Walls at the End of the World: The Green Mist, Next Stop Antarctica and the Tasmanian geographic imaginary

The Green Mist is a floating international blues entity which evolved in the deep south of Tasmania. Featuring former members of the Violent Femmes and Beasts of Bourbon, the Mist’s first album Next Stop Antarctica represents a vivid evocation of the peculiar strangeness of the island’s atmosphere, history and environment. Musician Julien Poulson’s father Bruce was a historian who lived in a derelict organic garlic farm in the small town of Southport; an area that is often bitterly cold, perpetually gloomy, bleak yet strangely beautiful. Bruce was one of the people who discovered the remains of a garden built in 1792 by French explorers in Recherche Bay, and this discovery was later used to help protect the site from logging. While his dad was dying of cancer, Julien helped him put together his final book about Recherche Bay’s history and later many of these old stories formed the basis of album tracks. Using The Green Mist as a case study, this paper will explore the links between physical place of production and creation; the use of both individual memory and historical narratives in song writing; and the extent to which these factors form part of a conscious or deliberate strategy.
REPRODUÇÃO, INTERPRETAÇÃO OU PERFORMANCE? ACERCA DA NOÇÃO DE PRÁTICA MUSICAL NA TRADIÇÃO CLÁSSICO-ROMÂNTICA VIENENSE

Resumo O termo “reprodução musical”, empregado por Theodor Adorno em grande número de fragmentos e manuscritos redigidos, aproximadamente, entre 1925 a 1965, pode ser definido, de forma elementar, como a realização sonora de uma obra musical com base em sua partitura. Tendo representado na tradição vienense da segunda metade do século XIX e das primeiras décadas do século XX uma prática em que o exercício da interpretação estava vinculado ao da composição, mantém-se hoje quase exclusivamente por meio da repetição de um repertório historicamente definido e delimitado. “Reprodução musical”, todavia, designa um processo multiforme de grande potencial produtivo e transformador, cuja abrangência conceitual aumenta sensivelmente quando se lhe atribuem a interpretação e a performance como elementos (ou princípios) ativos. Porque a análise do termo reprodução musical envolve a transliteração e a tradução de conceitos teóricos fundamentais de um idioma para outro, abordam-se primeiramente os critérios que norteiam a sua aplicação no contexto da tradição clássico-romântica vienense. Em seguida, são apresentadas algumas de suas implicações no debate atual sobre questões dele decorrentes.
On adressee prediction for remote hybrid meeting settings or how to use multiple modalities in predicting whether or not you are being addressed in a live hybrid meeting environment

To answer the question Who said what to whom? is a key part in understanding what is going on in group conversations. The question consists of three parts: who is the source of the message, what does the message entail, and to whom is the message addressed? This master thesis is about the third part of the question: to whom is the message addressed. More specifically, this work tries to create a method for automatically detecting whether a specific member in a group discussion is the intended addressee of an utterance or not. The general approach in this work is the use and creation of machine classifiers. In our case, the machine classifier functions as a piece of software that is working as an assistant for a specific participant in a meeting. The software can help in telling when the participant that it is operating for is being addressed. The details of this will become clear later on. For now, we look at what addressing is and how many different techniques we, humans, deploy in making sure our message reaches the intended audience. The first chapter continues by looking at why we would want to predict this behaviour automatically, and how other researchers in the field have done so.
The Skein Hash Function Family

Executive Summary Skein is a new family of cryptographic hash functions. Its design combines speed, security, simplicity , and a great deal of flexibility in a modular package that is easy to analyze. Skein is fast. Skein-512—our primary proposal—hashes data at 6.1 clock cycles per byte on a 64-bit CPU. This means that on a 3.1 GHz x64 Core 2 Duo CPU, Skein hashes data at 500 MBytes/second per core—almost twice as fast as SHA-512 and three times faster than SHA-256. An optional hash-tree mode speeds up parallelizable implementations even more. Skein is fast for short messages, too; Skein-512 hashes short messages in about 1000 clock cycles. Skein is secure. Its conservative design is based on the Threefish block cipher. The current best attack on the tweaked Threefish-512 is on 35 of 72 rounds, for a safety factor of just over 2.0. For comparison, at a similar stage in the standardization process, the AES encryption algorithm had an attack on 6 of 10 rounds, for a safety factor of only 1.7. Additionally, Skein has a number of provably secure properties, greatly increasing confidence in the algorithm. Skein is simple. Using only three primitive operations, the Skein compression function can be easily understood and remembered. The rest of the algorithm is a straightforward iteration of this function. Skein is flexible. Skein is defined for three different internal state sizes—256 bits, 512 bits, and 1024 bits—and any output size. This allows Skein to be a drop-in replacement for the entire SHA family of hash functions. A completely optional and extendable argument system makes Skein an efficient tool to use for a very large number of functions: PRNG, stream cipher, key derivation function, authentication without the overhead of HMAC, and personalization capability. All these features can be implemented with very low overhead. Together with the Threefish large-block cipher at Skein's core, this design provides a full set of symmetric cryptographic primitives suitable for most modern applications. Skein is efficient on a variety of platforms, both hardware and software. Skein-512 can be implemented in about 200 bytes of state. Small devices, such as 8-bit smart cards, can implement Skein-256 using about 100 bytes of memory. Larger devices can implement the larger versions of Skein to achieve faster speeds. Skein was designed by a team of highly experienced cryptographic experts from academia and industry , with expertise in cryptography, security analysis, software, chip design, and …

Modeled abductive inference for event management and correlation

This thesis describes a number of novel techniques for performing efficient event correlation in computer networks. We develop a new object-oriented event modeling methodology which is algorithm independent, and generalizes or is superior to the modeling capabilities of competing systems. We prove this assertion through the elegant modeling of a number of real world problems, simulation of the models of competing systems using our methodology, and a case study providing a quantitative analysis of the benefits of our methodology. We provide a probabilistically correct correlation algorithm which also generalizes or improves on the correlation component of competing systems. In addition, our algorithms improve correlation efficiency by pruning redundant information from the event model and preprocessing to further reduce correlation-time processing. These features are unique to our system. We demonstrate performance results which are conservatively measured to be greater than an order of magnitude better than those of competing systems.
Multilingual Text to Speech in embedded systems using RC8660

Most multilingual Test to Speech (TTS) systems are software applications which allow people with visual impairments or reading disabilities to listen the written material using computer. This paper describes an approach to make a multilingual TTS and embed it into the portable, low cost, and standalone embedded system to access and read electronic documents particularly in developing countries. There are several TTS such as Doubletalk, DECtalk, and Dolphin available in market, also there are some products using TTS such as Talking OCR, Bill Reader and Intel Reader, which are not affordable or multilingual. To design this system OMAP3530 an application processor board is considered as the hardware platform to process the language-independent parts of the application and RC8660 used as an integrated TTS processor .

Split time warping for improved automatic time synchronization of speech

In this paper, we propose an improvement to the robustness of automatic time synchronization of speech. The basic synchronization system consists of two parts. In the first part the timing relationship between two speech utterances is measured using the well-known technique of dynamic time warping (DTW). In the second part, the original signal (source) is time scaled to synchronize it with the utterance that is used as the timing reference (reference). Both for DTW and for the time-scaling of speech, numerous solutions are already known to exist, but automatic time-synchronization often yielded distorted results in realistic situations [1][2]. This paper presents a dedicated time warping algorithm that overcomes many of the original problems and achieves a more robust automatic synchronization.
Intensional and Extensional Aspects of Java Byte Code

Java Byte Code is a virtual machine language designed for portability and veri ability. A user can download a program in Java Byte Code from the World Wide Web, automatically verify that the program does not violate the language semantics, and execute the code on any machine. This mobility and security makes Java Byte Code well suited for distributed computing and active documents as well as for traditional applications. In this dissertation we consider Java Byte Code both as a language in itself (intensionally) and as a target language for compiling programs written in languages other than Java (extensionally. We investigate the intensional aspects of Java Byte Code through the development of Cream, a bytecode-to-bytecode optimizer with an inter-procedural side-e ect analysis. We show that Java Byte Code is just as optimizable as Java itself, and that some kind of interprocedural analysis is essential for obtaining good results. To study the extensional aspects of Java Byte Code, we have designed and implemented Kaemus, a compiler from Scheme to Java Byte Code, the rst such compiler to implement rst-class continuations and tail recursion properly. Kaemus illustrates that Java Byte Code, though usable, is a less-than-optimal target language for compiling programs from other languages than Java.
