This paper aims to provide control strategies for distributed micro-storage energy systems at the residential level to contribute to smart grid goals. The operation of local Energy Storage Systems (ESS) at homes in a Smart Community with distributed generation based of renewable energies is analyzed by simulation. Each individual home receive the active and reactive power set-points from the Smart Community Energy Management System (SCEMS), acting as an aggregator of resources in the community according to the expected demand and production. Besides, in case the ESS has got available capacity, once the SCEMS requirements are satisfied, it is used to inject the harmonic current components demanded by the household circuitry. It allows a local improvement in the power quality of the demanded current, and so contributes to the global power quality consumption of the community. Simulation results showing the operation of the local ESS are presented to validate the proposed control strategies.

The analysis of the perceptual properties of texture plays a fundamental role in tasks like semantic description of images or content-based image retrieval using linguistic queries. In this paper, we propose to model these properties by means of fuzzy partitions defined on the domain of some representative measures. In particular, we have focused our study on the properties of coarseness, contrast and directionality, that play a fundamental role in the human perception of texture. In our approach, the number of fuzzy sets in the partitions, as well as the parameters of the membership functions, are calculated by taking into account the relationship between the computational values given by the measures and the human perception of the corresponding property. The performance of the proposed modelling has been analyzed by applying the obtained fuzzy partitions in several experiments. © 2015 IEEE.

The mechanical performance of carbon nanotube （CNT） reinforced polymer com- posites is primarily controlled by the dispersive capacity and interracial shear strength of CNTs in polymer matrices. CNT functionalizations will improve dispersion and strengthen interracial bonding of CNTs in matrices. To understand the effects of different functionalization schemes on the interracial strength of CNT-polymer composites, pullout of the covalent, noncovalent, and mixed functionalized single-walled carbon nanotube （SWCNT） from polyethylene （PE） matrix was simulated by using molecular dynamics, respectively. The results show that the SWCNT-PE interracial shear strength is significantly improved by SWCNT functionalizations, particularly by mixed functionalization.

Smart meters are the cornerstone in the new conception of the electrical network or Smart Grid (SG), providing detailed information about users' energy consumption and allowing the suppliers to remotely collect data for billing. Nevertheless, their features are not only useful for the energy suppliers, but they can also play a big role in the control of the Microgrid since the recorded power and energy profiles can be integrated in energy management systems (EMS). In addition, basic power quality (PQ) disturbances can be detected and reported by some advanced metering systems. Thus, this paper will expose an example of Smart Meters integration in a Microgrid scenario, which is the Intelligent Microgrid Lab of Aalborg University (AAU). To do this, first the installation available in the Microgrid Lab will be introduced. Then, three different test scenarios and their respective results will be presented, regarding the capabilities of this system and the advantages of integrating the Smart Meters information in the Microgrid control.

This paper introduces a software to calculate two kind of fuzzy histograms on fuzzy color spaces considering recent advances in cardinality and fuzzy quantification techniques. One of the histograms is based on the cardinality of the fuzzy set of pixels that match a certain color (modelled by means of a fuzzy set over a given color domain) and the other one is based on the compatibility between cardinality measures and linguistic labels, i.e., the accomplishment degree of linguistic statements about the number or percentage of colors in images. The software is implemented in Java and includes several graphical tools to calculate histograms for fuzzy colors in an efficient and easy way. Graphical representations of the histograms can also be displayed with this software.

This paper describes the design of a new system architecture for monitoring and controlling purposes of a group of sensors and actuators within a wireless sensor network (WSN). This system can manage an undefined amount of clustered networks. The proposed system architecture enables Internet communications to reach theWSN in a highly efficient way. This structure reduces the bottleneck of the Internet/WSN bridge and the amount of messages inside the WSN when an Internet request arrives. Besides, each individual WSN implements an Intelligent Rule-Based System Automation (IRBSA) that performs the automation of the behaviour of the network motes according to the previously included rules. These rules describe the actions that are executed when all the conditions of that rule are met. Opposite to traditional approaches, IRBSA is placed in the WSN Header Mote rather than in the Internet server or in every mote. © Springer International Publishing Switzerland 2013.

Instruction Set Customization is a well-known technique to enhance the performance and efficiency of Application-Specific Processors (ASIPs). An extensive application profiling can indicate which parts of a given application, or class of applications, are most frequently executed, enabling the implementation of such frequently executed parts in hardware as custom instructions. However, a naive ad hoc instruction set customization process may identify and select poor instruction extension candidates, which may not result in a significantly improved performance with low circuit-area and energy footprints. In this paper we propose and discuss an efficient instruction set customization method and automatic tool, which exploit the maximal common subgraphs (common operation patterns) of the most frequently executed basic blocks of a given application. The speed results from our tool for a VLIW ASIP are provided for a set of benchmark applications. The average execution time reduction ranges from 30% to 40%, with only a few custom instructions.

In this paper we describe an approach for defining customized color descriptors for image retrieval. In particular, a customized fuzzy dominant color descriptor is proposed on the basis of a finite collection of fuzzy colors designed specifically for a certain user. Fuzzy colors modeling the semantics of a color name are defined as fuzzy subsets of colors on an ordinary color space, filling the semantic gap between the color representation in computers and the subjective human perception. The design of fuzzy colors is based on a collection of color names and corresponding crisp representatives provided by the user. The descriptor is defined as a fuzzy set over the customized fuzzy colors (i.e. a level-2 fuzzy set), taking into account the imprecise concept that is modelled, in which membership degrees represent the dominance of each color. The dominance of each fuzzy color is calculated on the basis of a fuzzy quantifier representing the notion of dominance, and a fuzzy histogram representing as a fuzzy quantity the percentage of pixels that match each fuzzy color. The obtained descriptor can be employed in a large amount of applications. We illustrate the usefulness of the descriptor by a particular application in image retrieval. © 2013 Springer-Verlag Berlin Heidelberg.

Application code and processor parallelization, together with instruction set customization, are the most common and effective ways to enhance the performance and efficiency of application-specific processors (ASIPs). Both the effective code parallelization and data/task parallelism exploitation, as well as effective instruction set customization, enable an ASIP to achieve a significant performance improvement using limited extra hardware resources. However, a naive parallelization or instruction set customization may not result in the required performance improvement, leading to a waste of computing and energy resources. Therefore, when performing parallelization or custom instruction selection, complex tradeoffs between processing speed, circuit area and power consumption must be closely observed. In this paper, we propose and discuss an efficient ASIP-based Multi-Processor System-on-a-Chip (MPSoC) design for ray-tracing, exploiting application parallelism and hardware replication-aware instruction set customization. Without hardware sharing among the custom instructions units, the proposed parallel ray-tracer MPSoC design with custom instructions achieves 77% speed up in comparison to a single microprocessor design with the default instruction set. However, with the replication-aware instruction set customization, the speed up increases to 81%. © Springer International Publishing Switzerland 2013.
