A Kuga fiber variety is a family of abelian varieties parametrized by a locally symmetric space and is constructed by using an equivariant holomorphic map of Hermitian symmetric domains. We construct a complex torus bundle T over a Kuga fiber variety Y parametrized by X and express its cohomology H∗(T ,C) in terms of the cohomology of Y as well as in terms of the cohomology of the locally symme...

In this paper we discuss how cognitive science may contribute to understanding the concepts of situatedness and situated play. While situatedness has become something of a catch-all term, it actually has several different meanings, ranging from “higher” social-cultural forms to “lower” sensori-motoric activities. We also discuss an often overlooked, but crucial aspect of situatedness, which is ...

A simple analytic design procedure for bireciprocal lattice wave digital filters (bireciprocal LWDFs) is presented with approximate linear phase. The design is started by replacing the odd order all-pass filter branch in the bireciprocal LWDF with a pure delay, leaving the other branch as an all-pass even function of z . Analytic design procedure is then formulated. Several design examples usin...

On April 2, 2012 the Eindhoven University of Technology published the first adaptive PhD thesis [4] describing the research on the adaptation language and engine GALE, and served (adaptively) by the GALE engine. The aim of the this research was twofold: to make the authoring of adaptive documents feasible without much technical knowledge, and to create an adaptation and user modeling service th...

This paper proposes a design method of separable denominator 2-D variable digital filters with high frequency tuning accuracy. In the proposed method, a parallel allpass structure with complex coefficients is used as a prototype structure of the 2-D variable digital filters. The proposed 2-D variable digital filters are composed of first-order complex allpass sections. To improve the frequency ...

Although largely absent from modern accounts of the Industrial Revolution , watches were the first mass produced consumer durable, and were Adam Smith's pre-eminent example of technological progress. In fact, Smith makes the notable claim that watch prices may have fallen by up to 95 per cent over the preceding century; a claim that this paper attempts to evaluate. We look at changes in the rep...

A promising method for estimation of the time-delay in continuous-time linear dynamical systems uses the phase of the allpass part of a discrete-time model of the system. We have discovered that this method can sometimes fail totally and we suggest a method for avoiding such failures.

A 42-year-old Caucasian man presented with a 15-year history of a widespread, persistent, pruritic eruption over his trunk and extremities. He was not on medication and had no relevant family history. On physical examination, multiple discrete, pinkish, hyperkeratotic 1 to 2 mm papules, arranged in a rippled pattern, were detected on the trunk and extremities (Figure 1). Widespread pruritic pap...

Communication errors are identified by the Joint Commission as the primary root cause of sentinel events across all categories. In addition, improving the effectiveness of communication among healthcare providers is listed as one of the Joint Commission's 2008 National Patient Safety Goals. Nursing programs are expected to graduate practice-ready nurses who demonstrate quality and safety in pat...

The working of a 19-bed isolation unit in a general hospital was studied from August 1975 to July 1976. A few patients received the highest degree of isolation, but infections in all categories were contained and patients at risk in the same unit were protected from infection.
