Microscale thermal engineering of electronic systems

The electronics industry is encountering thermal challenges and opportunities with lengthscales comparable to or much less than one micrometer. Examples include nanoscale phonon hotspots in transistors and the increasing temperature rise in onchip interconnects. Millimeter-scale hotspots on microprocessors, resulting from varying rates of power consumption, are being addressed using two-phase microchannel heat sinks. Nanoscale thermal data storage technology has received much attention recently. This paper provides an overview of these topics with a focus on related research at Stanford University.

Indices de escolarización en Enseñanza Media.

Contribuir a clarificar la situación actual en el Distrito Universitario de Oviedo de uno de los principales objetivos reiteradamente planteados por la política educativa: la escolarización en Bachiller Superior y COU. Escolarización en Bachillerato Superior en el Distrito Universitario de Oviedo. Se estudian las relaciones existentes entre la población demográfica total y la escolarizada, y de ésta última respecto a la población escolarizable que los planes oficiales del MEC estiman como 'desideratum' a alcanzar. Además, se analizan estadísticos como: total de efectivos escolares, ritmo de crecimiento en los últimos años, comparación con la media nacional y la relación entre escolarización y factores demográficos, socioeconómicos y proximidad de los centros de enseñanza. Datos del MEC, INE, Inspección de Enseñanza Media del Distrito. El ritmo de crecimiento del total de efectivos escolarizados en Bachillerato Superior ha sido altamente progresivo hasta el curso 1974-75, descendiendo considerablemente en el curso 75-76. El crecimiento en COU ha sido igualmente muy progresivo, no descendiendo en el curso 75-76. En el período de tiempo estudiado, el incremento de alumnos de Bachillerato siempre ha sido superior en la provincia de León respecto a Oviedo, dato que se manifiesta de forma inversa en COU. El crecimiento de la población total escolarizada en BUP ha sido superior que el de la población total nacional. El ritmo de crecimiento ha sido superior en COU que en BUP. Se aprecian claras diferencias en la escolarización entre diversas zonas. Pese al alto crecimiento de los porcentajes de escolarización, no se han alcanzado los objetivos propuestos por la política educativa. A nivel de comarcas, existen grandes diferencias entre la población escolarizada y escolarizable. La utilización de tasas e índices de escolarización a nivel provincial entraña considerables riesgos. Las tasas de escolarización en BUP y COU dependen más del factor socioeconómico que del demográfico y de las oportunidades de estudio que ofrece el medio.

Financial Information Mediation: A Case Study of Standards Integration for Electronic Bill Presentment and Payment Using the COIN Mediation Technology

Each player in the financial industry, each bank, stock exchange, government agency, or insurance company operates its own financial information system or systems. By its very nature, financial information, like the money that it represents, changes hands. Therefore the interoperation of financial information systems is the cornerstone of the financial services they support. E-services frameworks such as web services are an unprecedented opportunity for the flexible interoperation of financial systems. Naturally the critical economic role and the complexity of financial information led to the development of various standards. Yet standards alone are not the panacea: different groups of players use different standards or different interpretations of the same standard. We believe that the solution lies in the convergence of flexible E-services such as web-services and semantically rich meta-data as promised by the semantic Web; then a mediation architecture can be used for the documentation, identification, and resolution of semantic conflicts arising from the interoperation of heterogeneous financial services. In this paper we illustrate the nature of the problem in the Electronic Bill Presentment and Payment (EBPP) industry and the viability of the solution we propose. We describe and analyze the integration of services using four different formats: the IFX, OFX and SWIFT standards, and an example proprietary format. To accomplish this integration we use the COntext INterchange (COIN) framework. The COIN architecture leverages a model of sources and receivers’ contexts in reference to a rich domain model or ontology for the description and resolution of semantic heterogeneity.

Dissolution of Dynamic Electronic Institutions, a first approach: Relevant factors and causes

In the context of the digital business ecosystems, small organizations cooperate between them in order to achieve common goals or offer new services for expanding their markets. There are different approaches for these cooperation models such as virtual enterprises, virtual organizations or dynamic electronic institutions which in their lifecycle have in common a dissolution phase. However this phase has not been studied deeply in the current literature and it lacks formalization. In this paper a first approach for achieving and managing the dissolution phase is proposed, as well as a CBR process in order to support it in a multi-agent system

JISC TechDis Accessibility essentials guide: Making electronic documents more readable

The TechDis Accessibility Essentials Guide for Reading has been divided into the following three sections: Font colours and styles; Enlarging text and Navigating documents. These guides have been designed to give practical step-by-step information to enable anyone reading electronic material to amend its look and feel into a style which suits them, their audience or the context in which it is used.

EPS (Electronic Portfolio System)

In 2001, before the term “e-portfolio” was common parlance there was a perceived need to enable teachers in training to save, store, present and archive their electronically-based work so that it could be assessed by tutors. A Teacher Training Agency (TTA) Grant was used to design and implement an online system for trainee teachers to save evidence of their activities called Electronic Portfolio System (EPS). Over the years, its use and value has changed and, through the support of the Teacher Development Agency for schools (TDA), the system will continue to develop. The features of the system have grown organically because of technology changes and by tutors and mentors identifying affordances. This presentation will identify the principles and how they guide the development process. It will give an opportunity to elucidate the next stages in e-portfolio developments.

A User-Centric Approach to eCertificate for Electronic Identities (eIDs) Management in Mobile Environment

The use of electronic documents is constantly growing and the necessity to implement an ad-hoc eCertificate which manages access to private information is not only required but also necessary. This paper presents a protocol for the management of electronic identities (eIDs), meant as a substitute for the paper-based IDs, in a mobile environment with a user-centric approach. Mobile devices have been chosen because they provide mobility, personal use and high computational complexity. The inherent user-centricity also allows the user to personally manage the ID information and to display only what is required. The chosen path to develop the protocol is to migrate the existing eCert technologies implemented by the Learning Societies Laboratory in Southampton. By comparing this protocol with the analysis of the eID problem domain, a new solution has been derived which is compatible with both systems without loss of features.

Efecto de la glicemia materna en la monitoría electrónica fetal

Introducción: Después del ingreso de la monitoría fetal electrónica como estudio de bienestar fetal, se ha considerado por décadas que un aporte de carbohidratos a la gestante antes de la realización de la monitoría fetal influye en el reporte pero existen estudios que consideran que los niveles de glicemia materna no afecta la variabilidad de la monitoría fetal. Metodología: Se realizó un estudio de corte transversal, para evaluar el efecto de la glicemia materna en la monitoría fetal electrónica comparando los valores de glicemia materna con su resultado, según la categorización del ACOG. Las principales variables fueron las horas de ayuno, valores de glicemia, variabilidad de la monitoría fetal y presencia de aceleraciones. Resultados: Se incluyeron un total de 60 pacientes, que ingresaron al servicio de obstetricia y ginecología del Hospital Universitario Mayor Méderi en el periodo de estudio. No se encontraron diferencias estadísticamente significativas entre los resultados de monitoría fetal y los valores de glicemia materna. Ninguna paciente presentó monitoría categoría III (según categorización de la ACOG). Discusión Se requieren estudios analíticos más amplios para evaluar el papel de la glicemia en el resultado de la monitoría, pero el presente estudio sugiere que no existe relación entre la glicemia materna y el resultado de la monitoría fetal electrónica en la categorización del Colegio Americano De Ginecología Y Obstetricia (ACOG).
