Context-aware services platforms aim at supporting the handling of contextual information in order to provide better user-tailored services. This paper proposes a novel services platform architecture to support mobile context-aware applications, giving emphasis to the configurability of the platform’s generic functionality. The paper introduces concepts and a language to cope with configurabili...

holoprosencephaly is a rare congenital brain malformation resulting from failure of diverticulation and cleavage of primitive prosencephalon which occurs at 4 - 8th week of gestation and is usually associated with multiple midline facial anomalies. it is the most common forebrain developmental anomaly in humans with prevalence of 1/16,000 in live borns, an incidence as high as 1:250 in conceptu...

A Monte Carlo computer program has been used to calculate characteristics of the response of fully depleted silicon and germanium radiation detectors to monoenergetic gamma rays. Data for total absorption probability, intrinsic efficiency, escape peak efficiency and pulse height spectra are presented as functions of detector thickness and photon energy. Other parameters of interest in analysing...

We performed a first-principle, computational study of the optical properties of ruthenium dioxide. Our method employed a local density potential and the linear combination of atomic orbitals (LCAO). We circumvented a recently discovered spurious effect that is inherently associated with basis sets in variational calculations of the Rayleigh-Ritz type. Consequently, a significantly new feature ...

Guatemala es un país de gran diversidad biológica, la que ha permitido a diferentes investigadores productos naturales, obtener resultados interés y relevancia científica, principalmente sobre propiedades farmacológicas, sin embargo, hasta el momento se desconoce estructura molecular, conformaciones configuraciones exactas muchos los metabolitos secundarios responsables dichas propiedades. Por ...

We describe the use of an ambient display called Twitterspace for promoting awareness of events and member activities within our community centers. Content for the display pulls from the social networking platform Twitter. Tweets, which are the recent posts from community members, move across large screens placed in public rooms. Through the concept of community-at-aglance, we use these tweets ...
