This paper demonstrates the concept of using Heterogeneous networks (HetNets) to improve Long Term Evolution (LTE) system by introducing the LTE Advance (LTE-A). The type of HetNets that has been chosen for this study is Macro with Pico cells. Comparing the system performance with and without Pico cells has clearly illustrated using three well-known scheduling algorithms (Proportional Fair PF, ...

application-speci c design, architecture synthesis, bitwidth, clustering, embedded system, hardware accelerator, operation scheduling, resource allocation PICO is a system for automatically synthesizing embedded hardware accelerators from loop nests speci ed in the C programming language. A key issue confronted when designing such accelerators is the optimization of hardware by exploiting infor...

The genus Apodrosus Marshall is newly recorded for, and revised for Cuba. Nine new species are recognized as follows: Apodrosus alberti (type locality, Granma, Parque Nacional Pico Turquino), A. alternatus (type locality, Guantánamo, El Yunque), A. franklyni (type locality, Cienfuegos, Parque Nacional Pico San Juan), A. griseus (type locality, Santiago de Cuba, Siboney-Jutici Ecological Reserve...

In this paper, we address the issue of answering PICO (Patient/Problem, Intervention, Comparison, Outcome) clinical queries. The contributions of this work include (1) a new document ranking model based on a prioritized aggregation operator that computes the global relevance score based on the relevance estimation of the semantic facet sub-queries and (2) leverages the importance of the facets ...

In this paper, component carrier selection and beamforming on carrier aggregated channels in Heterogeneous Networks are proposed. The scheme jointly selects the component carrier and precoding (i.e. beamforming) vectors with the cooperation of the other cells to deal with the interference between Macro cell and Pico cell. The component carrier selection and beamforming is achieved by optimizing...

The design and implementation of personal communications systems requires the prediction of wave propagation relating to signal-to-noise and signal-to-interference calculation in a cellular system [93]. Small-cell network configurations especially microand pico-cell types are of major interest for urban environments. The commonly used criteria for the definition of a micro-cell is related to th...

Diffractive diffusers (phase gratings) are routinely used for homogenizing and beam shaping for laser beam applications. Another use for diffractive diffusers is in the reduction of speckle for pico-projection systems. While diffusers are unable to completely eliminate speckle they can be utilized to decrease the resultant contrast to provide a more visually acceptable image. Research has been ...
