In this work we investigate the performance of the Always Best Packet Switching (ABPS) operation approach. ABPS is a cross-layer wireless communication scheme that enables mobile terminals to exploit its multiple Network Interface Cards (NICs) concurrently. The ABPS software module installed on the mobile terminal determines dynamically the most appropriate NIC to use as single point of access to the Internet, and can switch to another NIC dynamically and transparently to the applications. For the assessment, we propose a performance model based on Markov reward models. Through it, we estimate the availability, reliability and throughput provided by ABPS, a standard SIP-based approach and conventional communication protocol employing a single NIC. Results show the performance improvements introduced by ABPS.

This paper describes an idea of one approach to small aircraft safety increasing. The project was founded as reaction on numbers of small simple-engine aircraft accidents in the Czech Republic and their usual reason - human factor. Pilots and schools in the Czech Republic recently started to use glass cockpits which can be used also in other way than pure EFIS. Glass cockpit system could be extended by appropriate safety software modules. software modules can be used in critical situations for flight analysis and giving appropriate advices to the pilot. Under this project was developed simple module navigating pilot to landing site when engine fails. Paper describes first version of EFIS with mentioned modules and also summarizes idea of designing system including testing approaches.

In this paper concept for dynamic frequency scaling algorithm implementation for low-power embedded systems is proposed. The algorithm is based on system's power consumption analysis in different operating modes. Depending on clock module settings, parameters for minimal power consumption are found. In this paper concept of a software module that would allow automatic frequency control in order to reduce power consumption and sastisfy timing constraints of program tasks is proposed.

Enterprise storage systems are generally shared by multiple servers in a SAN environment. Our experiments as well as industry reports have shown that disk arrays show poor performance when multiple servers share one RAID due to resource contention as well as frequent disk head movements. We have studied IO performance characteristics of several shared storage settings of practical business operations. To avoid the IO contention, we propose a new dynamic data relocation technique on shared RAID storages, referred to as DROP, Dynamic data Relocation to Optimize Performance. DROP allocates/manages a group of cache data areas and relocates/drops the portion of hot data at a predefined sub array that is a physical partition on the top of the entire shared array. By analyzing profiling data to make each cache area owned by one server, we are able to determine optimal data relocation and partition of disks in the RAID to maximize large sequential block accesses on individual disks and at the same time maximize parallel accesses across disks in the array. As a result, DROP minimizes disk head movements in the array at run time giving rise to high IO performance. A prototype DROP has been implemented as a software module at the storage target controller. Extensive experiments have been carried out using real world IO workloads to evaluate the performance of the DROP implementation. Experimental results have shown that DROP improves shared IO performance greatly. The performance improvements in terms of average IO response time range from 20% to a factor 2.5 at no additional hardware cost.

A number of V&V datasets are publicly available. These datasets have software measurements and defectiveness information regarding the software modules. To facilitate V&V, numerous defect prediction studies have used these datasets and have detected defective modules effectively. software developers and managers can benefit from the existing studies to avoid analogous defects and mistakes if they are able to find similarity between their software and the software represented by the public datasets. This paper identifies the similar datasets by comparing association patterns in the datasets. The proposed approach finds association rules from each dataset and identifies the overlapping rules from the 100 strongest rules from each of the two datasets being compared. Afterwards, average support and average confidence of the overlap is calculated to determine the strength of the similarity between the datasets. This study compares eight public datasets and results show that KC2 and PC2 have the highest similarity 83% with 97% support and 100% confidence. Datasets with similar attributes and almost same number of attributes have shown higher similarity than the other datasets.

The so-called fuzzy inference-grams (fingrams) constitute a novel and powerful tool for expert analysis of fuzzy rule bases at inference level in terms of co-fired rules, i.e., rules fired at the same time by a given input vector. A fuzzy rule base can be seen as a population made up of a set of individual rules which are competing and collaborating among them with the aim of yielding both good generality-specificity and interpretability-accuracy trade-offs. Thus, system behavior turns up from the existing relations among rules which can be easily analyzed by looking at the rule base as a fingram, i.e., as a social network made of nodes representing fuzzy rules. This paper introduces a new software module for fingram generation and analysis which is provided with the last version of GUAJE, a free software tool devoted to the generation of understandable and accurate fuzzy systems. Notice that, fingram analysis consists of studying the interaction among nodes in the network for the purpose of understanding the structure and behavior of the fuzzy rule base under consideration. It is based on the basic principles of social network analysis which have been properly incorporated into GUAJE and adapted to the design of fuzzy systems.

We propose a set of open-source software modules to perform structured Perceptron Training, Prediction and Evaluation within the Hadoop framework. Apache Hadoop is a freely available environment for running distributed applications on a computer cluster. The software is designed within the Map-Reduce paradigm. Thanks to distributed computing, the proposed software reduces substantially execution times while handling huge data-sets. The distributed Perceptron training algorithm preserves convergence properties, thus guaranties same accuracy performances as the serial Perceptron. The presented modules can be executed as stand-alone software or easily extended or integrated in complex systems. The execution of the modules applied to specific NLP tasks can be demonstrated and tested via an interactive web interface that allows the user to inspect the status and structure of the cluster and interact with the MapReduce jobs.

Quantifying Multiplexing Gains in a Wireless Network Cloud

The Wireless Network Cloud (WNC) [1] is a novel network architecture where wireless base-stations are implemented as software modules and multiple base-stations are consolidated to a single centralized computing platform. Due to the time-varying and random nature of base-station traffic, consolidation leads to multiplexing of statistically-varying base-station loads on a common hardware platform. In turn, this can lead to significant hardware reduction in the consolidated platform when compared to the distributed network. This paper represents the first analysis of such consolidation gain. Through traffic simulation experiments, we quantify the extent and variation of this multiplexing gain in a WiMAX base-station network in different traffic conditions. We show experimentally, that the obtained gain increases linearly with network size (number of base-stations). Further, we also show that the consolidation gain is higher when the consolidated base-stations face higher traffic intensity.
