A robot exploring an unknown environmentmay need to build a world model from sensor measurements. In order to integrate all the frames of sensor data, it is essential to align the data properly. An incremental approach has been typically used in the past, in which each local frame of data

call statecharts, extend conventional state-transition diagrams with essentially three olements, dealing, respectively, with the notions of hierarchy, concurrency and communication. These transform the language of state diagrams into a highly structured' and economical description language

. Control dependence5 are introduced to analogously represent only the essential control flow relationships of a program. Control dependences are derived from the usual control flow graph. Many traditional optimizations operate more efficiently on the PDG. Since dependences in the PDG connect

Many prominent theorists have argued that accurate perceptions of the self, the world, and the future are essential for mental health. Yet considerable research evidence suggests that overly positive selfevaluations, exaggerated perceptions of control or mastery, and unrealistic optimism

Abstract. Web users ’ concerns about their privacy result in reduction of online shopping activity. Widely spread Web marketing is not possible without an appropriate protection of customers ’ privacy. The significance of privacy in electronic commerce is illustrated in this article. We present a classification of Web privacy risks and describe an evolution of privacy enhancing technologies. It includes a review of Client-side Utilities, new protocol – P3P, simple Third Party Proxy Servers and more sophisticated Chaining with Encryption technique. The possibilities of mentioned solutions and their disadvantages are specified. Effective solutions are characterized by low performance and high costs of their realization. Electronic society’s unrealized demands are highlighted against this background. Our proposal of a new method of providing versatile anonymity for Web users is included in the summary of this discussion. The solution overcomes mentioned weaknesses. 1

Our research in statistical cognition uses both qualitative and quantitative methods. A mixed method approach makes our research more comprehensive, and provides us with new directions, unexpected insights, and alternative explanations for previously established concepts. In this paper, we review four statistical cognition studies that used mixed methods and explain the contributions of both the quantitative and qualitative components. The four studies investigated concern statistical reporting practices in medical journals, an intervention aimed at improving psychologists’ interpretations of statistical tests, the extent to which interpretations improve when results are presented with confidence intervals (CIs) rather than p-values, and graduate students ’ misconceptions about CIs. Finally, we discuss the concept of scientific rigour and outline guidelines for maintaining rigour that should apply equally to qualitative and quantitative research.

conserved developmental systems that read an (almost) universal language encoded in DNA base pairs. As such, life is arranged hierarchically with a foundation of discrete, unblendable units (codons, and, for the most part, genes) capable of combining to create increasingly complex and virtually limitless

To affirm Sojourner Truth as a powerful rhetor who advanced the equality and empowerment of women, a study examined several of her speeches on women's suffrage. Although the value of using such role models as Sojourner Truth has been demonstrated in various grade levels, and in the study of history and English, the approach is too seldom employed in today's college classes studying rhetorical criticism. Additional analysis of this female voice is overdue in the field of speech communication. The goal of Sojourner Truth's life was to move the United States toward equality of the sexes, making it appropriate that the critical method used in the study is that of feminist criticism. The study analyzed how in these speeches, and from her perspective as a freed female slave of African descent, Sojourner Truth presented the situation of women; how women perceived society; and the way Sojourner Truth challenged post-Civil War assumptions about females. (The three speeches analyzed are attached. Contains 21 references.) (Author/NKA) Reproductions suppiied by EDRS are the best that can be made from the original document. 'S
