Recently, Gutiérrez-Naranjo and Leporati considered performing basic arithmetic operations on a new class of bioinspired computing devices - spiking neural P systems (for short, SN P systems). However, the binary encoding mechanism used in their research looks like the encoding approach in electronic circuits, instead of the style of spiking neurons (in usual SN P systems, information are encoded as the time interval between spikes). In this work, three SN P systems are constructed as adder, subtracter and multiplier, respectively. In these devices, a number is inputted to the system as the interval of time elapsed between two spikes received by input neuron, the result of a computation is the time between the moments when the output neuron spikes. © 2011 IEEE.

This paper shows the result of an analysis pertaining to the applicability of RESTful web services (RESTful WS) in solving various software and data integration scenarios in control centers for the electric power system domain. There are many possible ways to enhance power system software/data integration by combining RESTful WS and the IEC 61970 set of standards. The goal of this paper is to highlight those lines of integration in control centers, where the benefits of leveraging RESTful WS are most noticeable. The importance of selecting the most prominent integration scenarios from the viewpoint of RESTful WS stems from the fact, that not all integration problems are naturally fitted for RESTful WS. Assuming a type of RESTful WS, which wraps the resource oriented power system data model defined in the IEC 61970-301 Common Information Model (CIM) and the generic query interface defined in IEC 61970-403 Generic Data Access (GDA), the paper demonstrates that such a RESTful WS may be successfully utilized in many concrete integration situations. As an added advantage, a RESTful WS atop of existing IEC 61970 standards can significantly loose the couplings between different software packages used in power system control centers. We have realized several pilot projects using real life power system data models (some used in CIM interoperability tests) to assert the outcome of our feasibility study. This study clearly shows that RESTful web services are a powerful tool for solving numerous power system software and data integration problems in control centers. © 2011 IEEE.

MmView: A web-based viewer of the mmCIF format

BMC Research Notes 2011年第1期4卷 1-8页

Background: Structural biomolecular data are commonly stored in the PDB format. The PDB format is widely supported by software vendors because of its simplicity and readability. However, the PDB format cannot fully address many informatics challenges related to the growing amount of structural data. To overcome the limitations of the PDB format, a new textual format mmCIF was released in June 1997 in its version 1.0. mmCIF provides extra information which has the advantage of being in a computer readable form. However, this advantage becomes a disadvantage if a human must read and understand the stored data. While software tools exist to help to prepare mmCIF files, the number of available systems simplifying the comprehension and interpretation of the mmCIF files is limited. Findings: In this paper we present mmView - a cross-platform web-based application that allows to explore comfortably the structural data of biomacromolecules stored in the mmCIF format. The mmCIF categories can be easily browsed in a tree-like structure, and the corresponding data are presented in a well arranged tabular form. The application also allows to display and investigate biomolecular structures via an integrated Java application Jmol. Conclusions: The mmView software system is primarily intended for educational purposes, but it can also serve as a useful research tool. The mmView application is offered in two flavors: as an open-source stand-alone application (available from http://***/projects/mmview) that can be installed on the user's computer, and as a publicly available web server. © 2011 Svozil et al;licensee BioMed Central Ltd.

It is impossible to plan in advance unpredictable phenomena at monitoring, diagnosis and control of industrial batch and continuous equipment and processes such as chemical composition of the raw materials, the process leads to unexpected reactions and changes its parameters, etc. The agent is active, a program entity, has its own ideas how to perform the tasks of the own agenda. Agents perceive, behave ＂reasonably＂, communicate with other agents. Agents can represent equipment and operations in batch processes as recommended by the ISA $88. Jadex system is based on Java language and on FIPA org. recommendations. The description of ripening tank T406 and recipe for yogurt production in the holding of MADETA Corp. in the Czech Rep. It is described modeling and displaying of＂normal＂ and error, fault unit state of the ripening tank. Agents are within the Jadex system and describing the behavior of ripening tank T406 with state diagrams-automata and assist in diagnosing of fault states. States are described in XML language-SCXML （State Charts XML）. Jadex control Center-JCC represents a major access point to use for operating in real time.

Object detection and recognition is a common problem related to fault diagnosis in engineering or analysis of changes in biomedical data observations. As such data are often contaminated by noise it is necessary to reduce its effect during this process as well. The paper presents the application of wavelet transform to perform these task using the three dimensional wavelet decomposition, coefficients thresholding and object reconstruction. The proposed method is verified for simulated data at first and then applied for processing of backbone parts to emphasize its selected components. The goal of the paper is in (i) the presentation of the three-dimensional wavelet transform, (ii) discussion of its use for volume data de-nosing, and (iii) proposal of the following data extraction to allow their classification. The paper compares numerical results achieved by the use of different wavelet functions and thresholding methods with the experience of an expert to propose the best algorithmic approach to this problem.

Arithmetic coding is a widely applied compression tool with superior coding efficiency to other entropy coding methodsHowever, it suffers from the error resilience and complexityIn this paper, the integer implementation of binary arithmetic coding with forbidden symbol for error resilience is studiedCoding redundancies for employing different quantization coefficients in probability representation and cost effective backtracking distance in bits for maximum a posteriori(MAP) decoding are studied in depthWe observe that the optimal quantization coefficients are independent of forbidden symbol and the probabilities of source and the cost effective backtracking distance is related to the source entropy and the given forbidden symbol probabilitiesSuch observations are also demonstrated by extensive experiments.

In this paper, applications of the interacting multiple model (IMM) nonlinear filters to ultra-tightly coupled GPS/INS integrated navigation system. An ultra-tight GPS/INS architecture involves the integration of in-phase (I) and quadrature (Q) components from the correlator of a GPS receiver with the INS data. The error caused by linearization as in the extended Kalman filter (EKF) can be avoided using the unscented Kalman filter (UKF), which employs a set of sigma points by deterministic sampling, can efficiently deal with the nonlinear problem. The interacting multiple model (IMM) has the configuration that runs in parallel several model-matched state estimation filters, which exchange information (interact) at each sampling time. The use of IMM provides the appropriate value of process noise covariance so as to maintain good estimation accuracy and tracking capability. Performance assessment for EKF/UKF and IMMEKF/IMMUKF is carried out. The results show that the proposed IMMUKF algorithm demonstrates remarkable improvement in navigation estimation accuracy as compared to the conventional approaches.
