作者： K. Kociuszkiewicz F. Morgan K. Kepa Dept. of Electron. Eng. Ireland Nat. Univ. Galway Ireland Electronic Engineering Department National University of Ireland Galway Computer Architecture Group Wroclaw University of Technology Poland

A reconfigurable system-on-chip (rSoC) architecture incorporating embedded uClinux operating system and multiple co-processing nodes has been reported (Williams and Bergmann, 2004). Our paper extends this platform to incorporate transparent management of reconfigurable hardware resources. This provides a convenient and flexible means for rapid application development of rSoC systems. The co-processor allocation and task management system is described. Details of the implementation are also included

A scheme was obtained using synthesis of Petri nets sharing a kind of subnet, according to process of several enterprises sharing a plant to produce some product. First, the Petri net model of single enterprise in sharing a plant to produce some product was set up. Second, the global Petri net model was obtained through using shared subnet synthesis method. Using the global Petri net model people can actualize synchronization and save resources. Several conditions were proposed for the synthesis net of free choice nets (FC) {asymmetric choice nets (AC)} is a FC net {AC net}. Some conditions of the structural liveness preservation by the shared subnet synthesis of Petri nets were obtained. These results are useful for studying the properties of Petri synthesis nets and establishing models for large complex system.

In order to access target information while getting an overview of the entirety of a large-scale database, a search must be carried out in parallel with various modifications to the frame of reference and dynamic organization of the information. In this research, this type of database search is realized through an information access space dynamically constructed of hyperlinks based on an arbitrary frame of reference. The authors propose a new concept and structure for the frames of reference and develop a mechanism for dynamically linking individual database records with multiple information access spaces, dynamically constructed on the basis of declarative definitions of these frames of reference. The authors also provide a three-dimensional interface for editing frames of reference and for spatial navigation threaded by these links. These operations correspond to query processing by narrowing down the subject tables and joining multiple tables;the user can gradually narrow his focus and arrive at the target information by dynamically modifying his frame of reference and repeating spatial movements. In this paper, a three-dimensional interface is developed and database searches using that interface are evaluated;it is shown that this technique makes it possible to quickly access target information. © 2006 Wiley Periodicals, Inc.

Recently, large-scale protein-protein interactions were recovered using the similar two-hybrid system for the model systems. This information allows us to investigate the protein interaction network from a systematic point of view. However, experimentally determined interactions are susceptible to errors. A previous assessment estimated that only ~10% of the interactions can be supported by more than one independent experiment, and about half of the interactions may be false positives. These false positives might unnecessarily link unrelated proteins, resulting in huge apparent interaction clusters, which complicate elucidation for the biological importance of these interactions. Address this problem, we present an approach to integrate, assess and characterize all available protein-protein interactions in model organisms yeast and fly. We first integrate all available protein-protein interaction databases of yeast and fly, and merge all the datasets. We then use machine learning techniques to score the reliability for each interaction, and to rigorously validate the scoring scheme of yeast protein-protein interactions from different aspects. Our results show that this scoring scheme provides a good basis for selecting reliable protein-protein interaction dataset

Radio Frequency Identification (RFID) system which is based on a contactless sensing identification technology causes dramatic change in the exiting business management strategies. The technologies in the fields of inventory automation and production automation will be highly promoted with the application of RFID. Today most research work of RFID applications concentrate on using RFID tag as a product description device. In this paper, we propose a new usage development. The RFID tag will also be treated as a portable electronic form. With uniqueness of every RFID tag and the digital signature technique, the RFID tag can be as a secured storage device. A demonstration system for the inventory works of yacht equipments suppliers is presented to show the workability of this new development. The most notable characteristic of this system is the non-interrupted e-process under the failure condition of computer network which will be switched to used manual process in before.

The Collaborative Large-scale Engineering Analysis Network for Environmental Research (CLEANER) Project Office has been established with funding from the National Science Foundation (NSF) to the University of Illinois Urbana-Champaign (UIUC) and a coalition of 11 other institutions. The project office is coordinating the creation of a strategic plan consisting of research, cyberinfrastructure, and education plans that set forth a roadmap for the collaborative engineering analysis network for the study of environmental problems. This report will be completed by July 2007 and requires input from K-12 educators, administrators and other stakeholders in K-12 education. This paper describes the CLEANER project, provides an example of the CLEANER Education Committee's vision for the K-12 area and lists contacts for further information. The intention of this paper is to elicit input from the K-12 engineering education community, including K-12 educators, on how the CLEANER Education Plan could better meet the future needs of K-12 students and educators © American Society for Engineering Education, 2006.

TaSe model for long term time series forecasting

TaSe model for long term time series forecasting

8th International Workshop on Artificial Neural Networks, IWANN 2005: Computational Intelligence and Bioinspired Systems

There exists a wide range of paradigms and a high number of different methodologies applied to the problem of Time Series Prediction. Most of them are presented as a modified function approximation problem using I/O data, in which the input data is expanded using outputs at previous steps. Thus the model obtained normally predicts the value of the series at a time (t + h) using previous time steps (t - τ1), (t - τ2),..., (t - τn). Nevertheless, learning a model for long term time series prediction might be seen as a completely different task, since it will generally use its own outputs as inputs for further training, as in recurrent networks. In this paper we present the utility of the TaSe model using the well-known Mackey Glass time series and an approach that upgrades the performance of the TaSe one-step-ahead prediction model for long term prediction. © Springer-Verlag Berlin Heidelberg 2005.

TSK models are a very powerful tool for function approximation problems given a dataset of input/output data. Given a global error function to approximate, there are several methodologies for training (adjust the parameters and find the optimal structure) the TSK model. Nevertheless, this strategy implies that the interpretability of the rules comprising the neuro-fuzzy TSK system as linearizations of the nonlinear subjacent system can be lost. Several recent works have addressed this problem with partial success, sometimes performing a tradeoff between global accuracy and local models interpretability. In this paper we propose an accurate modified TSK neuro-fuzzy model for function approximation that solves the cited problem, and that furthermore allows us to interprete the output of the rules as the Taylor Series Expansion of the system output around the rule centres. © Springer-Verlag Berlin Heidelberg 2005.
