Great interest in recent years has been devoted to mobile communications. The research effort has been directed to increasing the capacity of radio systems by applying space reuse techniques. Higher efficiency in the usage of the available frequency spectrum can be obtained either by reducing the cell size, thus requiring the provision of new base stations, or by reusing the available spectrum ...

NASA Langley Research Center (LaRC) developed the Langley Standard Real-Time Simulation in C++ (LaSRS++) to consolidate all software development for its simulation facilities under one common framework. A common framework promised a decrease in the total development effort for a new simulation by encouraging software reuse. To judge the success of LaSRS++ in this regard, reuse metrics were extr...

By applying recent advances in the standards for distributed computing, we have developed an architecture for a CORBA implementation of a library of platform-independent, sharable problem-solving methods and knowledge bases. The aim of this library is to allow developers to reuse these components across different tasks and domains. Reuse should be cost effective; therefore, the library will inc...

Results From October 2014 to January 2015, we included 28 participants. Fifteen (54%) were female, average age was 67 (SD 14) yrs. and average BMI was 30 kg/m2 (SD 8). Household monthly income was less than R$ 1.000 (US$ 317) for 68% of the participants. Median time of insulin therapy was 10 yrs. (range 6 to 20 yrs.); 23 (74%) selfadministered insulin injections. Twenty-seven (96%) participants...

Along with the popularization of endoscopic surgeries, the reuse of disposable single-use devices (SUDs), which may cause various risks, has become a considerable issue globally. We conducted the survey by questionnaires for the operating room (OR) head nurses to obtain hospital-based answer. First survey was done for three months in 2000 by sending the questionnaires to 2,224 hospitals. The se...

This is the project report for the Course CS573 Optimization Compilers. The goal of the project is to study the reuse distance of several of the applications included in the MediaBench Suite. 1 Methodology The reuse distance of a memory location or variable of a program is the number of individual memory references between two consecutive references to the same memory location or variable. The ...

The present paper focuses on the application of the base station cooperation (BSC) technique in fractional frequency reuse (FFR) networks. Fractional frequency reuse is considered to be a promising scheme for avoiding the inter-cell interference problem in OFDMA cellular systems, such as WiMAX, in which the edge mobile stations (MSs) of adjacent cells use different subchannels for separate tran...

The interference mitigation technique based on fractional frequency reuse (FFR) provides improved cell-edge performance with similar overall cell capacity as that of systems with the frequency reuse factor of one. Furthermore, frequency sub-band allocation by FFR has the benefit of allowing flexibility for the deployment of femto-cells through frequency partitioning. Determination of a proper f...

In this article, we propose two levels of resource allocation method in a converged scenario for Macro and Femtocells LTE system. We use a Soft Frequency Reuse for guaranteeing the Quality of Service (QoS) for different Service Data Flows (SDFs) in the converged wireless networks. The first level of our method includes the use of bandwidth allocation between macro and femtocells and admission c...
