Abstract: Fine scalable video coding is a common method for video quality scalable of H264 and MPEG-4, but it has not been used on AVS as yet. This paper presents a new algorithm of fine granularity scalability based on AVS. The DCT residue coefficients of the FGS enhancement layer proposed in this paper are firstly scanned by zigzag and then scaled with the energy distribution characteristic of frequency domain. Then, the scalable coefficients are coded by bit-plane coding and Exp-Golomb coding. Finally, we simulate the algorithm on the software codec model version rm52k of AVS-P2. The experimental results show that the ameliorated scalable coding method can improve the coding efficiency obviously compared with the original FGS in terms of average PSNR.

Abstract: Based on user requirement techniques, this paper suggests a new approach to the generation of a building performance simulation tool interface prototype. This approach requires the Unified Modelling Language (UML) and scenario specifications for analysing user interactions with the computer program core. At the level of user interface specifications, designer can draw interfaces but it is difficult to specify their dynamic behaviour. Coloured Petri-nets are used in specification and check on the behaviour of these interfaces before their implementation. The EnergyPlus input data definition (IDD) file is provided as an example to illustrate the process of generating an executable interface prototype which can be used for scenario validation, and can be evolved towards the target interface tool. The result of the overall approach is a specification consisting of a global coloured Petri-net which can be analysed by means of a simulation together with the generated and refined IDD interface prototype [Copyright &y& Elsevier]

Abstract: Key differences of precisely measuring currents on wafer based solar cells and multi-junction solar cells are shortly described at the beginning of the paper. In the next section, the impact of precise Standard Test Condition (STC) measurements on the energy yield prediction by PV simulation software is reviewed, with special mention of the Staebler-Wronski Effect. Solar modules containing amorphous silicon absorbers perform in moderate latitudes in a cyclic way: hot season with higher output and cool season with lower output. Both, spectral variations of the irradiance as well as temperature rise during irradiance are reported in literature contributing to this cycling behaviour, which finally is not an issue but a feature of this technology. In consequence, a ‘design to geography’ approach is suggested for module manufacturers, allowing for higher energy yields even without considerably increasing nameplate power under STC. Standardisation, which highlights the energy yield in addition to STC nameplate power, is identified as urgently needed. A better understanding of amorphous silicon based multi-junction PV modules can only be gained, if more spectrally resolved data acquisition is performed and evaluated for high and low geographic latitudes. Instead of a ‘static’ temperature coefficient, amorphous silicon modules are better characterised with the ‘effective’ temperature coefficient which can become positive e.g. in building integrated heat-insulating PV elements.

Abstract: A formal semantic model is proposed in this paper which focus on model-driven development for agent-based systems. Agent models are described with algebra specifications, and morphisms are used to describe the relationships between agent models, and the morphism types imply the different semantics of agent interactions. The typed category theory is used to formally describe agent models and their mapping relations, and thus the precise semantic meanings for them are provided. An agent-based intelligent tutoring system is given as a case to illustrate the application of this approach. The formal semantic model can be used to judge whether a transformation satisfies some property preservation constraints or not, and it can provide an effective support for model-driven agent-based software development.

Abstract: There have been strong demands for a fast full-system simulation platform targeted multicore embedded systems to facilitate software developing and debugging. In this paper, we describe the design and implementation of a fast multithreaded full-system simulator called PCSim as a first step towards such a simulation platform. PCSim models a dual-core PowerPC platform named HPCN-MPC8641D produced by FreeScale with two PowerPC E600 cores and plenty of peripherals. It also models exceptions and interrupts to support whole-system applications including OS. It is based on an interpretive simulation technology to provide flexibility and meanwhile implemented as a multithreaded program to accelerate multicore simulation. It provides three simulation modes: 1) the application mode in which target binary programs run directly on the simulator without any guest OS supports; 2) the full-system mode in which full-system applications including OS are simulated; 3) the CUDA-like mode in which the simulator acts just like the NVIDIA CUDA Device. Currently, PCSim supports several peripherals included in the target platform, and can run a tailored Linux OS with an average execution rate of more than 10.5 MIPS. We instantiate as many as 128 virtual cores to carry out a matrix multiplication computation in the CUDA-like mode and prove it works. [Copyright &y& Elsevier]

Abstract: Most of the current detection models for software behavior focus on the integrity detecting of its running path, but they rarely consider detecting the function realization integrity in each stage of the software running path. Therefore, dynamic credibility detection model based on scene mining for software behavior called SCDM is proposed in this paper. First of all, this model describes the integrity of various stages’ function implementation by introducing the concept of scene. Secondly, the model used association rules and sequence pattern algorithm in scene mining. Both of the algorithms can extract the hidden and valuable association information from the captured scene information set. And the mining result is used for credibility detection of software behavior. Finally, the results of simulation experiments indicate that CDMBSM model has a good detection performance.

Abstract: Sequence clustering is significant for analyzing software fault. The existing similarity measures of sequence clustering are inexact for clustering software fault. In this paper, a software fault feature clustering algorithm called ECA is proposed. In ECA the similarity of fault sequence is defined by global and local similarity measure (GLSM) which considers both the items contained in sequence and the order of items occurrence. The clusters are collected according to the entropy of sequences that is computed by global and local similarity. The sequence with the smallest entropy is selected as the centroid of each clustering, and then the clusters are obtained based on the largest similarity between the unselected sequence and the clustering centroid. The optimal number of clusters is determined by the average silhouette coefficient. In order to analyze the fault type, the sequences to be analyzed are matched to each cluster and classed into the most similar cluster. Experimental results show that ECA improves the precision of clustering and reduces the matching scope of the software fault feature. [Copyright &y& Elsevier]

Abstract: During the last decades, spatio-temporal data sets have drawn great attention in research areas and industrial applications. For the purpose of building better predictive models for spatio-temporal data analysis tasks, the data sets are mainly analyzed by traditional Data Mining (DM) tools and Geographical Information Systems (GIS) cooperatively. Usually the geospatial attributes of data need to be generated manually by analyst from GIS. When build/train a model and use the trained model to do prediction, the lack of automation of the geospatial attributes generation makes the task inefficient and hardly repeatable. Still, there are very few tools that can perform spatiotemporal data analysis tasks alone and automate the above procedure. In this paper, we propose a service-based spatio-temporal data analysis framework, which can leverage existing data mining tools and geographical information systems, and perform spatio-temporal data analysis tasks in an integrative manner. In this framework, a data analysis task is divided into traditional data mining tasks and geospatial related tasks, each of which is executed on an existing tool/software. The entire procedure is automated by a bundle of web services. User can analyze data efficiently and repeatably by simply accessing the service. We also develop a discription model based on the Predictive Model Markup Language (PMML) and Keyhole Markup Language (KML) to describe the geospatial related data mining models in our framework. This enables information exchanging capability with other data mining tools and geospatial rendering services. A case study on spatial association rule mining demonstrates the usability of the framework. [Copyright &y& Elsevier]
