Column-oriented database has gained popularity as Data Warehousing data and performance issues for Analytical Queries have increased. Each attribute of a relation is physically stored as a separate column, which will help analytical queries to work fast. The overhead is incurred in tuple reconstruction for multi attribute queries. Each tuple reconstruction is joining of two columns based on tup...

The Double Gate FinFET has been designed for 90nm as an alternative solution to bulk devices. The FinFET with independent gate (IDG) structure is designed to control Vth. When the Vth is controlled the leakage current can be decreased by improving its current driving capability. The metal used for the front gate and back gate is TiN. Here the device performance is compared using nitride spacer ...

Efficient sequence alignment is one of the most important and challenging activities in bioinformatics. Many algorithms have been proposed to perform and accelerate sequence alignment activities. Among them SmithWaterman (S-W) is the most sensitive (accurate) algorithm, however, the fact that it is the most computationally intensive algorithm makes it necessary to implement hardware acceleratio...

Health care expenditure in Ireland has reached 9.5% of GDP (2009 data). This figure is similar to the UK and is in line with most other European countries apart from France and the Netherlands which are higher at over 11%. In most western societies health spending is rising faster than economic growth, a trend that was first observed in the 1970s and has continued unchecked. The spending on hea...

Performance Improvement CME (PI CME) is an educational activity in which clinicians retrospectively assess their current clinical practice, choose areas for improvement and implement interventions based on treatment guidelines and health care standards, and then re-evaluate their clinical practice to assess the improvements made. This PI CME activity focuses on improving the safety and efficacy...

For mobile users without antenna arrays, transmission diversity can be achieved with cooperative transmissions, or by multi-branch system which uses the relays reached by the transmitter. When there is only one relay that can be reached by the transmitter, the transmission diversity can be obtained by a multi-hop system, then we emulate the (2 transmit antennas, 2 receive antennas) cooperative ...

Performance of ATM networks depends on switch performance and architecture. This paper presents a simulation study of a new dynamic allocation of input buffer space in ATM switching elements. The switching elements are composed of input and output buffers which are used to store received and forwarded cells, respectively. Efficient and fair use of buffer space in an ATM switch is essential to g...

Authors have proposed new methodology in recent years for evaluating the improvement in prediction performance gained by adding a new predictor, Y, to a risk model containing a set of baseline predictors, X, for a binary outcome D. We prove theoretically that null hypotheses concerning no improvement in performance are equivalent to the simple null hypothesis that Y is not a risk factor when co...

In this paper, we present the review and the focus is on the Convolution coding used in WiMAX system and the difference between WiMAX system and Wi-Fi Technology is shown. The architecture used on WiMAX to drive a service over a radius upto several kilometers is configured in the same way as a traditional cellular network with base stations.
