Abstract:A Self-Modifying Protocol (SMP) is a set of instructions, rules, or conventions that can be changed by the systems that communicate with the help of that protocol. This concept is expected to be of great importance for the next generation of intelligent distributed systems. At this time, the idea is still difficult to be captured into working computer code. In this paper, Self-Modifying Automata (SMA) is adopted for the description and design of such protocols. We illustrate the idea of using SMA for protocol design through some solid examples. A solution framework is suggested for incorporating SMPs. One self-regulating and self-modifying communication mechanism is presented for implementing SMPs. In addition, real-time on-the-fly data-driven code is proposed to implement the prototypes of these ‘autonomous protocols’. © 2007 Inderscience Enterprises Ltd.

Abstract:Researchers have proposed intelligent product-brokering applications to help facilitate the m-commerce shopping process. However, most algorithms require explicit, user-provided feedback to learn about user preference. In practical applications, users may not be motivated to provide unrewarded and time-consuming feedback. By adopting a cognitive approach, this paper investigates the possibility of replacing user feedback with user behavioral data analysis during product browsing. By means of evolutionary algorithms, the system is able to derive corresponding models that simulate the user's shopping behavior. User group profiling is also implemented to help identify the user's shopping patterns. Upon simulations of trial cases with consistent and rational shopping patterns, our experimental results confirm this approach being promising. The system shows high accuracy in detecting the preferences of the user. The algorithms are also portable and effective across different products. © Imperial College Press.

9.Classification Of Cerebral Palsy Gait By Kernel Fisher Discriminant Analysis

Source：International journal of hybrid intelligent systems,2008,Vol.

Abstract:Cerebral palsy (CP) is generally considered as a non-progressive neuro-developmental condition that occurs in early childhood and is associated with a motor impairment, usually affecting mobility and posture. Automatic accurate identification of cerebral palsy gait has many potential applications, for example, assistance in diagnosis, clinical decision-making and communication among the clinical professionals. In previous studies, support vector machine (SVM) and some other pattern classification methods like neural networks have been applied to classify CP gait patterns. The objective of this study is to first further investigate different classification paradigms in the CP gait analysis, particularly the Kernel Fisher Discriminant Analysis (KFD) which has been successfully applied to many pattern recognition problems and identified as a strong competitor of SVM. The component obtained by KFD maximally separates two classes in the feature space, thus overcoming the limitations of linear discriminant analysis of being unable to extract nonlinear features representing higher-order statistics. Using a publicly available CP gait dataset (68 normal healthy and 88 with spastic diplegia form of CP), a comprehensive performances comparison was presented with different features including the two basic temporal-spatial gait parameters (stride length and cadence). Various cross-validation testing show that the KFD offers better classification accuracies than the support vector machine and is superior to a number of other classification methods such as decision tree, multiple layer perceptron and k nearest neighbor.

10.An image indexing and searching system based both on keyword and content

Author：Zhang, N;Song, Y

Source：ADVANCED INTELLIGENT COMPUTING THEORIES AND APPLICATIONS, PROCEEDINGS: WITH ASPECTS OF THEORETICAL AND METHODOLOGICAL ISSUES,2008,Vol.5226

Abstract:Content-based image retrieval (CBIR) has certain advantages over those pure keyword-based. CBIR indexes images by visual features that are extracted from the images. This may save the effort spent on the manual annotation. However, because low-level visual features, such as colour and texture, often carry no high-level concepts, images retrieved purely based on content may not match with the intention of the user. The work presented in this paper is an image retrieval system that bases both on text annotations and visual contents. It indexes and retrieves images by both keywords and visual features, with the purpose that the keywords may mend the gap between the semantic meaning an image carries and its visual content. Tests were made on the system that have demonstrated that such a hybrid approach did improve retrieval precisions over those pure content-based.

Source：IEEE TRANSACTIONS ON CIRCUITS AND SYSTEMS FOR VIDEO TECHNOLOGY,2008,Vol.18

Abstract:In this paper, model-based approaches for real-time 3-D soccer ball tracking are proposed, using image sequences from multiple fixed cameras as input. The main challenges include filtering false alarms, tracking through missing observations, and estimating 3-D positions from single or multiple cameras. The key innovations are: 1) incorporating motion cues and temporal hysteresis thresholding in ball detection; 2) modeling each ball trajectory as curve segments in successive virtual vertical planes so that the 3-D position of the ball can be determined from a single camera view; and 4) introducing four motion phases (rolling, flying, in possession, and out of play) and employing phase-specific models to estimate ball trajectories which enables high-level semantics applied in low-level tracking. In addition, unreliable or missing ball observations are recovered using spatio-temporal constraints and temporal filtering. The system accuracy and robustness are evaluated by comparing the estimated ball positions and phases with manual ground-truth data of real soccer sequences.

Abstract:In information age, reliability of digital manufacturing equipment has a large impact on throughput, productivity and executing predictive maintenance. Accurate reliability forecasts can provide a good assessment of machine performance in order to execute predictive maintenance effectively. This paper investigates a methodology of applying support vector machines(SVMs) to predict reliability in computerized numerical control(CNC) machine tool of digital manufacturing system. SVM is capable to solve nonlinear regression and times series problems lie on conducting the structural risk minimization principle seeking to minimize an upper bound of the generalization error rather than minimize the training error. A real reliability data (for 42 suits) of CNC machine tool were employed as the data set. SVM can be trained to learn the relationship between past historical reliability indices and the corresponding targets, and then future reliability or failures can be predicted. The experimental results demonstrate that the SVM prediction model is a valid potential for predicting system reliability and failures. © 2008 IEEE.

15.Initiate, Develop, and Implement a Strategic 360 Degree Performance Appraisal System to improving Employee Development for China-based Enterprises

Author：Pak, D

Source：2008 INTERNATIONAL CONFERENCE TECHNOLOGY MANAGEMENT AND INNOVATION IN CHINA: CHALLENGES AND OPPORTUNITIES IN THE 21ST CENTURY, BOOKS I AND II,2008,Vol.

Abstract:Performance Management has evolved from a simple method to where either the employees performance if below standard or above and a decrease or an increment was warranted. This prehistoric method left little to the overall development of the appraisal. Now, performance management is a structured interaction between team leader and subordinate, an annual or bi annual process whereby one could argue a SWOT analysis of the employee past performance is undertaken. Many organizations, not all, link their performance appraisal to merits. In turn, performance is still merit based, but opportunity to identify weaknesses and further training and development are included. As any tool or technique, criticisms will always prevail, either through misunderstandings or the fear of change etc. From this two paradoxes arise; "Some have even suggested that the process is so inherently flawed that it may be impossible to perfect it" (Derren, 1990) and Performance Appraisals "the most crucial aspect of organizational life" (Lawrie, 1990). This suggests that organizations require an amicable yardstick to measure performance. The author implies that times has changed; organizations require employees to go beyond efficient and effective, but rather. to distinguish themselves. Organizations require a tool to enhance performance, 360 Degree provides that, but without with out proper planning a framework to initiate, develop and, implement, disaster is imminent. This paper attempts to provide the guidelines required to satisfy that need.

16.TADL - An architecture description language for trustworthy component-based systems

Author：Mohammad,Mubarak;Alagar,Vasu

Source：Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics),2008,Vol.5292 LNCS

Abstract:Existing architecture description languages mainly support the specification of the structural elements of the system under design with either only a limited support or no support to specify non-functional requirements. In a component-based development of trustworthy systems, the trustworthiness properties must be specified at the architectural level. Analysis techniques should be available to verify the trustworthiness properties early at design time. Towards this goal we present in this paper a meta-architecture and TADL, a new architecture description language suited for describing the architecture of trustworthy component-based systems. The TADL is a uniform language for specifying the structural, functional, and nonfunctional requirements of component-based systems. It also provides a uniform source for analyzing the different trustworthiness properties. © 2008 Springer-Verlag Berlin Heidelberg.

Abstract:Photovoltaic (PV) generation has now-a-days proved to be a cost-effective method for renewable power generation with minimum environmental impact. Due to environmental and economic benefits, PV is now being widely deployed as a distributed energy resources (DER) in distributed generation systems or microgrids. Extensive laboratory-based research and simulation studies are being performed for assessing its effectiveness as DER in microgrids. Simulation studies mostly involve development of mathematical models which can account for the variation of PV output with solar irradiance and ambient temperature as well as the simulation of MPPT feature that is built in the inverters usually interfaced with the PV arrays. Simulation studies of microgrids with interconnected DERs and elaborate control schemes often warrants the development of simple and robust mathematical models for PV arrays that would pose low mathematical burden on the system, have low data storage requirements and which can be represented by standard block sets of a modelling software. At the same time, the models should be able to simulate the weather dependent electrical behaviour of the PV modules. This paper reports on the development or a DC voltage source model of a polycrystalline PV Array in MATLAB Simulink and its performance analysis under various loading and weather conditions as well as the application of the model to develop a load shedding scheme for a stand-alone PV system.

Abstract:In this paper, a new mathematic model for calculating available transfer capability (ATC) of power system in power market is presented. This model considers the bidding of generators, bus locational marginal price (LMP) and system security constraints. The objective function is to maximize the total active power consumption for load in sink area. The constraint is the system operation in a security and economy way. A bi-level leader-follower decision-making measure is taken to solve the problem. Relative to the former ATC models which only consider system security constraints, this model is more in accord with the market reality and its solution can guide all parties in market to make decision more efficiently. The numerical simulation results in IEEE30 bus system demonstrate the validity of this model. © 2008 DRPT.
