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.

3D models are a new kind of cross-media resource which can be frequently seen in the network. Since the amount of them is very huge now, content-based retrieval can help to recognize a certain object or retrieve similar ones from the giant database. This paper presents a new method for deriving 3D moment invariants and uses them as shape descriptors for the representation of 3D models. They are insensitive to surface noise and can be used in pervasive environment conveniently. We also illustrate how to build up experimental system and simulate 3D shape retrieval in wireless environment

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

Existing multithreaded network processors architecture with multiple processing engines (PEs), aims at taking advantage of blocked multithreading technique which executes instructions of different user-defined threads in the same PE pipeline, in explicit and interleave way. Multiple PEs, each of which is a multithreaded processor core, process several packets in parallel to hide long memory access latency. Most of them are optimized for throughputs mostly in data-plane. In future network workloads, the boundaries between data-plane and control-plane become blurred, so that PEs are demanded not only wire speed packet forwarding on data-plane, but also highly intelligent and increased complex packet processing function on control-plane. In this paper, we analyze SMT's short latency tolerance potential when used in out-of-order and dynamic scheduling PE cores. We show in this paper that 2-4 issue SMT provides an excellent short memory and branch latency tolerance, which gain higher instructions throughout as well as much simpler structures. © Springer-Verlag Berlin Heidelberg 2005.

We propose a simulation-based method in the verification of SoC bus system. By the method, constrained-random vector is used to make simulation first;then a coverage analysis is made in the simulation process until a certain coverage statistics is obtained. Finally, the test vector is manually generated. We use this method to verify a SoC system and get a satisfactory result by reducing the time of simulation effectively.

The accuracy of concrete strength inspection has a great influence on the safety evaluation of the building. In order to increase the accuracy, Fuzzy Neural Network (FNN) was built up to evaluate concrete stmngth: It takes full advantage of the characteristics of the common concrete testing methods: drill and rebound, and the abilities of FNN including automatic learning, generation and fuzzy logic inference. The experiment shows that the max relative error of the predicted results is 1.12%, which is satisfied with the requirements of the engineering. The method effieieatly maps the complex non-linear relationship between the drill values and the rebound values, and provides a efficient way for the concrete strength inspection and evaluation.

The interface and structure of a package of applied programs for the description of plastic deformation by slip in f.c.c. materials are developed. The mathematical model used for calculations is based on the set of differential equations of balance of deformation defects in f.c.c. materials. The processes of generation and annihilation of deformation defects have essentially different rates, and the system of ODE (ordinary differential equations) is stiff. Application of implicit absolutely steady methods is necessary in this situation, because classical Runge-Kutta's methods can require much time for calculations. In this case the use of implicit multistep Gear's method of the variable order for decision the system of ODE is more effective. The applied programs for the description of plastic deformation are oriented for the users who have different qualification in programming and are not require an experience of decision of ODE. © 2003 7th Korea-Russia Intl Sym on science.

The naming of natural features, such as hills, lakes, springs, meadows etc., provides a wealth of linguistic information;the study of the names and naming systems is called onomastics. We consider a data set containing all names and locations of about 58,000 lakes in Finland. Using computational techniques, we address two major onomastic themes. First, we address the existence of local dependencies or repulsion between occurrences of names. For this, we derive a simple form of spatial association rules. The results partially validate and partially contradict results obtained by traditional onomastic techniques. Second, we consider the existence of relatively homogeneous spatial regions with respect to the distributions of place names. Using mixture modeling, we conduct a global analysis of the data set. The clusterings of regions are spatially connected, and correspond quite well with the results obtained by other techniques;there are, however, interesting differences with previous hypotheses. © Springer-Verlag Berlin Heidelberg 2003.

It is widely accepted that use of an Application Specific Instruction Set Processor (ASIP) in an embedded system can provide a solution which is much more flexible than ASICs and much more efficient than standard processors in terms of performance and power consumption. However a lack of an acceptable design methodology and supporting tools for ASIPs limits their use even today. We present in this paper a methodology for design space exploration of high performance VLIW ASIPs by modeling Application Specific Functional Units in Trimaran Compiler Infrastructure. To demonstrate the effectiveness of our strategy we consider two important applications FFT and Kalman Filter and perform compute intensive operations in these applications via special Functional Units. The results we obtain are very promising with up to 2× speed improvement.

Aboard current ships, such as the DDG 51, engineering control and damage control activities are manpower intensive. It is anticipated that, for future combatants, the workload demand arising from operation of systems under conditions of normal steaming and during casualty response will need to be markedly reduced via automated monitoring, autonomous control, and other technology initiatives. Current DDG 51 class ships can be considered as a manpower baseline and under Condition III typical engineering control involves seven to eight watchstanders at manned stations in the Central Control Station, the engine rooms and other machinery spaces. In contrast to this manning level, initiatives such as DD 21 and the integrated engineering plant (IEP) envision a partnership between the operator and the automation system, with more and more of the operator's functions being shifted to the automation system as manning levels decrease. This paper describes some human systems integration studies of workload demand reduction and, consequently, manning reduction that can be achieved due to application of several advanced technology concepts. Advanced system concept studies in relation to workload demand are described and reviewed including. Piecemeal applications of diverse automation and remote control technology concepts to selected high driver tasks in current DDG 51 activities. Development of the reduced ship's crew by virtual presence system that will provide automated monitoring and display to operators of machinery health, compartment conditions, and personnel health. The IEP envisions the machinery control system as a provider of resources that are used by various consumers around the ship. Resource needs and consumer priorities are at all times dependent upon the ship's current mission and the availability of equipment pawnbrokers.
