The PICO-N system automatically synthesizes embedded nonprogrammable accelerators to be used as co-processors for functions expressed as loop nests in C. The output is synthesizable VHDL that defines the accelerator at the register transfer level (RTL). The system generates a synchronous array of customized VLIW (very-long instruction word) processors, their controller, local memory, and interf...

| Handover control of indoor pico-cellular radio systems becomes unstable due to severe mul-tipath fading in buildings. The previously proposed decision-avoided handover algorithm can greatly improve the robustness of indoor handover control. This paper analyzes soft handover control algorithms for indoor DS-CDMA systems. The soft handover algorithm exhibits the same robustness as the decision-...

Paper proposes a new design and a simulation model for the pico base station based on IEEE 802.16e standard and evaluates its performance in a mutihop-relay and mesh networks. The proposed base station design allows multihoprelay communications and thus opens a possibility for the proposed base station to be an element of mesh networks. The conventional IEEE 802.16e base stations interconnected...

It is expected that projector phones and pico projectors will be very widespread in a few years. This paper reports a formative field study in which we analyzed over a period of three days what people think about such devices, what they would use them for and how they react when seeing others using them. We report our findings regarding the usage of project phones for different applications and...

BACKGROUND In patients with acute respiratory distress syndrome, whether inverse ratio ventilation differs from high positive end-expiratory pressure (PEEP) for gas exchange under a similar mean airway pressure has not been adequately examined. The authors used arterial oxygenation, gastric intramucosal partial pressure of carbon dioxide (PiCO(2)), and pH (pHi) to assess whether pressure-contro...

Introduction Diffuse optical tomography is the use of diffuse light to create an image of the desired target. In our case, the CamBoard pico

We proposed a design for a LASER pico-projector with a low speckle contrast value and high contrast ratio that maintains system efficiency. The method for speckle contrast reduction utilizes two diffusers and a Voice Coil Motor (VCM) oscillator. The two different diffusers for a high contrast ratio and high system efficiency can be divided into two categories. In Category 1, the speckle contras...

The aim of this paper is to show the special characteristics of the indoor environment related to radio propagation and furthermore to radio network planning. The aspects of the radio network planning are highlighted especially for Wideband Code Division Multiple Access (WCDMA) radio access technology that is used widely in the third generation mobile networks. Moreover, the detailed planning p...

The Long Term Evolution-Advanced (LTE-A) heterogeneous network (HetNet), which can increase the capacity of LTE-A, is composed of high power macrocells and low power picocells. However, unbalanced loading between macro and pico cells and inter-cell interference problems are two major performance bottlenecks in LTE-A heterogeneous networks (HetNets). We propose Self-Organizing Network (SON)-base...
