Objects in the world exhibit complex interactions.When captured in a video sequence, some interactions manifest themselves as occlusions. A visual tracking system must be able to track objects which are partially or even fully occluded. Occlusion is a difficult problem in target tracking, especially...

This paper presents state-of-the-art silicon-based bandstop filters for the realization of microwave system-on-a-chip (SOC) communication systems. The characteristics of the bandstop filters are designed by the adjustment of the geometric dimensions of the filters in order to meet different system requirements....

We are developing an artificial stock market model with investor agents in order to analyze characteristics of a market price. In this paper, we analyze the effects of agent’s reaction rate to technical indicators in a financial market. Intensive experiments have suggested that trend follow investor...

Resource allocation in the econophysics of competing supermarket chains, modelled as a Multi-Agent System is addressed in the context of finding good method to increase the competitiveness of the company in networked economy. A special swapping algorithm which increased the local clustering effects of...

A link in production network is usually a creditor-debtor relationship. If a firm goes into financial insolvency state or bankruptcy, then firms on its upstream can have secondary effect from the bankruptcy. By using the recent 10 years data of bankruptcy in japan, we show that these causes of ``link...

The purpose of this paper is to study vendor selection problem with multi-vendor and multi-item in iron & steel industry. Firstly, the native fuzziness, derived from some uncertainty information, of some parameters in decision-making objectives is analyzed. After that, a fuzzy multiobjective programming...

This paper adopts the grey prediction methods, to investigate the return and volatility of major index futures among American and Eurasian markets. The grey relational theory and GM(1,N) model are further used to observe the volatility spillover effect and find the main influence factor in the volatility...

Some approaches such as path indexing, labeling, and numbering scheme have been proposed in order to facilitate query of XML data. The indexes derived by these approaches must be rebuilt if XML data is updated. The method LSDX (Labeling Scheme for Dynamic XML data) can dynamically add new labels without...

Combining the concepts of balanced scorecard, fuzzy set theory and entropy, a systematic fuzzy multiple criteria decision making (MCDM) for airlines operating performance evaluation is proposed. A hierarchical structure is constructed through the concept of balance scorecard includes four perspectives:...

Building on the framework presented in The Nature of Creative Development (Stanford U. Press, 2006), I describe an approach for representing researchers' focuses of research activity in a field; the approach is based on use of a knowledge representation framework. Application is made to the field of...

In order to reduce the bias of linguistic recognitions among the group decision makings, this study develops “fuzzy multiple preference model” with two stages to better determining the suitable service innovation. A real numerical application in the chain wholesale has also been demonstrated.

This research utilizes the Agent-Based Model to clarify microscopic and macroscopic links between investor behavior and price fluctuations in the financial market. This analysis places focus on the role that investors’ overconfidence plays in the financial market. As a result of this analysis, it has...

This paper addresses hidden structure visualization adaptive to human’s prior understanding. The degree of understanding is parameterized by temperature used in the human-interactive annealing process along with stable deterministic crystallization algorithm. This adaptive nature is demonstrated with...

Image up-sampling is found to be a very effective technique useful in today’s digital image processing applications or rendering devices. In image up-sampling, an image is enhanced from a lower resolution to a higher resolution with the degree of enhancement depending upon application requirements. It...

Three books are reviewed, namely Masao Nagasawa: Schroedinger Equations and Diffusion Theory. Birkhaeuser, Basel Boston Berlin, 1993. 332 pages. David Wick (with a mathematical appendix by William Farris): The Infamous Bounary - Seven Decades of Controversy in Quantum Physics. Birkhaeuser. Boston Basel...

Consider an enterprise that wants to expand its business to multiple cities in global and to be one of well-known multinational enterprises (MNEs). Suppose the MNE hopes each planning investment subsidiary gleans a specific target return within a constant time horizon. Under this premise, this paper...

Mobile agents (MA) needs to migrate to several host to accomplish its task .Migration strategy is responsible for planning out an optimal migration path ,which ensures mobile agent to complete its task correctly and efficiently at the minimum cost .This paper describe the strategy adopted by a mobile...

It is a challenge area in the field of ad hoc networks to support prioritized routing for time sensitive applications, such as multimedia communications, IP telephony and interactive games. However the existing protocols did not consider the special battery discharging behavior of wireless devices. The...

Mobile Ad Hoc network (MANET) is a collection of mobile nodes connected through a wireless link resulting in formation of temporary network without any assistance from existing infrastructure or any kind of centralized administration. The performance of an Ad Hoc network depends on the kind of routing...

Switching system implies data transmission between two communicating entities. This transmission can be either via trunks or it can be completely wireless, technically termed as Telephone Switching and Mobile switching, respectively. We report the implementation of a switching system using very high...

Recognizing the importance of developing renewable energy resources, the Highways Agency commissioned a preliminary scoping study in 2001 to explore available methods and assess the possibility of renewable energy generation being exploited within the highway network. Among the various means of transportation,...

License plate detection process can be divided in two parts 1] plate extraction, 2] character segmentation. License plate detection relies on illumination conditions, background and mainly on camera resolution. There is absence of any common standard to compare various algorithms for a LPD system, because...

Correlation techniques are used to find whether the electrocardiogram (ECG) is normal or abnormal. These correlation techniques could be further used to detect the type of abnormality present in the abnormal ECG. Reference ECG signals could be stored for all type of abnormalities and the test ECG signal...

In this paper, an attempt has been made to design Edge Feed Microstrip , VSWR, phase chactersrtics and observed effect of different parameter by hanging height for all substrate in terms of return losses. The matching act as high radiator for low dielectric and low radiator for high dielectric

In this paper Time Domain Least Mean Square (LMS) algorithm and Wavelet Transform Domain Least Mean Square (WDLMS) algorithm with Daubechies wavelets are used to minimize the undesired noise from speech signals. The performance of this algorithm using different Daubechies wavelets db1, db5 and db10 are...

Low-Energy Adaptive Clustering Hierarchy (LEACH) is one of the most popular distributed cluster-based routing protocols in wireless sensor networks. Clustering algorithm of the LEACH is simple but offers no guarantee about even distribution of cluster heads over the network. LEACH doesn’t ensure even...

With the advancement of networking technology it is anticipated to have Internet like functionality in tactical network. However, unlike commercial network the tactical networks operate under severe environment and resources constraints. Moreover, the MANET architecture and shared resources of wireless...
