Information before unblinding regarding the success of confirmatory clinical trials is highly uncertain. Estimates of expected future power which purport to use this information for purposes of sample size adjustment after given interim points need to reflect this uncertainty. Estimates of future power at later interim points need to track the evolution of the clinical trial. We employ sequential models to describe this evolution. We show that current techniques using point estimates of auxiliary parameters for estimating expected power: (i) fail to describe the range of likely power obtained after the anticipated data are observed, (ii) fail to adjust to different kinds of thresholds, and (iii) fail to adjust to the changing patient population. Our algorithms address each of these shortcomings. We show that the uncertainty arising from clinical trials is characterized by filtering later auxiliary parameters through their earlier counterparts and employing the resulting posterior distribution to estimate power. We devise MCMC-based algorithms to implement sample size adjustments after the first interim point. Bayesian models are designed to implement these adjustments in settings where both hard and soft thresholds for distinguishing the presence of treatment effects are present. Sequential MCMC-based algorithms are devised to implement accurate sample size adjustments for multiple interim points. We apply these suggested algorithms to a depression trial for purposes of illustration.

The idea behind Quiz Challenger was to create knowledgeable environment in which user can share and enhance knowledge by giving and accepting challenge. The Quiz challenger is developed on JavaScript used for front-end and node JS used for back-end development. To dealt with database we use MongoDB.

Realizar entrevistas toma tiempo; por lo tanto no es posible utilizar este método para recopilar toda la información que se necesite en la investigación; incluso el analista debe verificar los datos recopilados utilizando unos de los otros métodos de recabación de dato

Using WebRTC we are trying to develop a prod- uct called 'Ping' used for audio, mult-video, file and screen sharing. Ping uses WebRTC for the source of data exchange and XMPP Server for signalling and transporting. Ping works on Browser to Browser connections instead of naive client server approach. Ping guarentees high scalability and upto 60% more efficiency than existin

Entre las ventajas que tiene la domótica esta la protección del hogar e integración familiar, añadir valor a la vivienda, mejorar la calidad de vida (acondicionar el clima, aislamiento de equipos, encendido y apagado de luces, regular la energía y automatizar los distintos sistemas) de las personas que viven en ella y en este caso la que nos identifica es el ahorro energético que 'añade inteligencia a las casas
