Abstract A fuzzy extractor derives uniformly random strings from noisy sources that are neither reliably reproducible nor uniformly random. The basic definition of fuzzy extractor was first formally introduced by Dodis et al. and has achieved various applications in cryptographic systems. However, it has been proved that a fuzzy extractor could become totally insecure when the same noisy random source is extracted multiple times. To solve this problem, the reusable fuzzy extractor is proposed. In this paper, we propose the first reusable fuzzy extractor based on the LPN assumption, which is efficient and resilient to linear fraction of errors. Furthermore, our construction serves as an alternative post-quantum reusable fuzzy extractor.

AbstractIn this paper I shall examine the use and misuse of some astronomical terminology as it is commonly found in the literature. The incorrect usage of common terms, and sometimes the terms themselves, can lead to confusion by the reader and may well indicate misconceptions by the authors. A basic definition of the Be phenomena is suggested and other stellar characteristics whose interpretation may change when used for non-spherical stars, is discussed. Special attention is paid to a number of terms whose semantic nature is misleading when applied to the phenomena they are intended to represent. The use of model-dependent terms is discussed and some comments are offered which are intended to improve the clarity of communication within the subject.

This paper explains the basic definition of ignition, combustion and description of the ignition system functionality. The ignition systems are divided according to established criteriums into the most used types and descriptions of each ignition system components. It focuses on ignition timing and circumstances that affect it and how they influence the observed parameters. I am using ignition timing as an instrument for the observation and optimization of ignition. These practices are tested on piston engine in the practical part of this paper. It describes the modification of the timing curve, measuring of engine power and comparison between each curve. It is an analysis of engine performance under different conditions. The most efficient timing curve is chosen and further evaluated. The used engine for this paper was a rebuild from a car engine used in Trabant 601, VEB Automobilwerke automobile.

This chapter deals with puns. The classification of puns is discussed and a basic definition of pun is provided: a text in which a sequence of sounds must be interpreted with a formal reference to a second sequence of sounds and two incongruous meanings are triggered by this process. Puns may come from ambiguity, or paronymy (puns that are similar in sound). The phonetic distance is the measure of how far two paronyms may differ and still be considered puns. The position of the connector (the ambiguous or paronymic element) and the disjunctor (the element in the text that triggers the recognition of the pun) are discussed. A Cratylistic motivated folk-theory of language is shown to underlie puns in the minds of speakers. Finally, a discussion of the psycholinguistics of puns completes the chapter.

Many other authors have attempted to define deference, though none of those definitions were grounded in a full description of the practices of US federal courts. Many of those other efforts were overtly normative, aimed at deriving an ideal structure for deference that can be used to criticize actual practices. Nonetheless, some of those efforts offer valuable insights even for a purely descriptive project. We reject efforts to limit the definition of deference only to instances in which the deferring body changes its decision in some way; mere consideration of another’s decision is sufficient to constitute deference. From Paul Horwitz we take the idea that deferees must be attentive to their role in a system of deference, and from Aileen Kavanaugh we take the idea that deference can sometimes be justified on prudential, or strategic, grounds. But consideration of others’ views does not change our basic definition of deference as: “The giving by a legal actor of some measure of consideration or weight to the decision of another actor in exercising the deferring actor’s function.”

Electronic collaboration (e-collaboration) is operationally defined here as collaboration using electronic technologies among different individuals to accomplish a common task (Kock & D’Arcy, 2002; Kock, Davidson, Ocker, & Wazlawick, 2001). This is a broad definition that encompasses not only computer-mediated collaborative work but also collaborative work that is supported by other types of technologies that do not fit most people’s definition of a “computer.” One example of such technologies is the telephone, which is not, strictly speaking, a computer—even though some of today’s telephone devices probably have more processing power than some of the first computers back in the 1940s. Another example of technology that may enable e-collaboration is the teleconferencing suite, whose main components are cameras, televisions, and telecommunications devices.

It is the age of the social web, where people express themselves by giving their opinions about various issues, from their personal life to the world’s political issues. This process generates a lot of opinion data on the web that can be processed for valuable information, and therefore, semantic annotation of opinions becomes an important task. Unfortunately, existing opinion annotation schemes have failed to satisfy annotation challenges and cannot even adhere to the basic definition of opinion. Opinion holders, topical features and temporal expressions are major components of an opinion that remain ignored in existing annotation schemes. In this work, we propose OpinionML, a new Markup Language, that aims to compensate for the issues that existing typical opinion markup languages fail to resolve. We present a detailed discussion about existing annotation schemes and their associated problems. We argue that OpinionML is more robust, flexible and easier for annotating opinion data. Its modular approach while implementing a logical model provides us with a flexible and easier model of annotation. OpinionML can be considered a step towards “information symmetry”. It is an effort for consistent sentiment annotations across the research community. We perform experiments to prove robustness of the proposed OpinionML and the results demonstrate its capability of retrieving significant components of opinion segments. We also propose OpinionML ontology in an effort to make OpinionML more inter-operable. The ontology proposed is more complete than existing opinion ontologies like Marl and Onyx. A comprehensive comparison of the proposed ontology with existing sentiment ontologies Marl and Onyx proves its worth.

Human habits are considered to be an important root of societal problems. The significance of habits has been demonstrated for a variety of behaviors in different domains, such as work, transportation, health, and ecology, suggesting that habits have a pervasive impact on human life. Studying and changing habits in societal context requires a broad view of behavior, which poses a challenge for applying basic models to complex human habits. We address the conceptualization and operationalization of habits in the current literature and note that claims about the role of habits in societal context rarely agree with the basic definition of habits as goal-independent behavior. We consider future directions that are important for making progress in the study of habit change in societal context.
