Recently many applications like fire simulation bring more interests in the extents of moving objects. Present research usually focuses on the positions of moving objects. The proposed models are more compatible for the position management. As a result, tracking the continuously changing extents of moving objects is becoming increasingly necessary. This paper proposes a novel model that can represent...
We modified the Java code of the MOSS simulator to develop a robust virtual memory simulator which allows the user to easily switch between different page replacement algorithms including FIFO, LRU, and optimal replacement algorithms. The simulator clearly demonstrates the behavior of the page replacement algorithms in a virtual memory system, and provides a convenient way to obtain their page fault...
Petri nets are a well-known paradigm for simulating dynamic systems. Coloured Petri nets are characterised by tokens with attributes whose values are changed by events in the model. They cannot play an active role in the system behaviour. Using them to model human beings, with continuously changing attributes and simple decision-making abilities, would require a large number of auxiliary elements...
Group decisions are more complex compared to single decision making, because a number of contradicting factors are involved. These include individuals' personal opinions, goals and stakes resulting in a social procedure, where negotiation and strategy plays a critical role. In this paper we present an integrated intelligent module for the development of a Group Decision Support System. The approach...
When there is an outbreak of a certain disease, gathering individual patient history is a time-critical task. So is the allocating and finding medical products for the remedy. To address this problem, we introduce an infrastructure with Web services that provides a timely and effective way for the government, healthcare institutions, and businesses to cooperate, focusing on the outbreak notification...
To enhance the practicability of management laws and demonstrate their suitable adoption for management concerns within Web-Technology, we endeavour to smoothly and accurately bridge the gap between current advances in SLAs at the deployment level and our conceptual business-level based management laws. We propose to take advantage of the most recent event-driven (ECAs) Web standards with particular...
The Hong Kong Police Force (HKPF) is currently utilizing static images stored in computers or on printed hard- copies to recognize Missing Persons (MP) and Wanted Persons (WP). This method is unsuitable for today's rapidly changing environment. The Missing Person Unit (MPU) is still using plastic sheets with human distinguishing characteristics to sketch the face of the MPs. This approach is inefficient...
The identification and labeling of non-hierarchical relations are among the most challenging tasks in ontology learning. This paper describes an approach for suggesting ontology relationship types to domain experts based on implicitly learned relations from a domain corpus. The learning process extracts verb- vectors from sentences containing domain concepts. It computes centroids for known relationship...
Mobile phones in today's era are not just small devices that provide the means of communication, rather, they are equipped with more processing power, storage capacity and battery performance. Now, the hand held devices are not only service consumers but are also capable of hosting and providing services to their peers. These services deployed on mobile devices bring in the idea of mobile Web services...
The Fuzzy Radial basis function Neural Networks (FRBFN) for software cost estimation is designed by integrating the principles of RBFN and the fuzzy C- means clustering algorithm. The architecture of the network is suitably modified at the hidden layer to realise a novel neural implementation of the fuzzy clustering algorithm. Fuzzy set-theoretic concepts are incorporated at the hidden layer, enabling...
This paper introduces a new multidimensional sessions comparison method (MSCM) using dynamic programming. Our method takes into consideration of different session dimensions such as the page list, the time spent on each page, and the length of each session. The method showed more accurate results than other known methods such as sequence alignment method (SAM), multidimensional sequence alignment...
Content delivery networks (CDNs) provide an efficient support for serving "resource-hungry" applications while minimizing the network impact of content delivery as well as shifting the traffic away from overloaded origin servers. However, their performance gain is limited since the storage space in CDN's servers is not used optimally. In order to manage their storage capacity in an efficient...
As more and more approaches focus on service oriented architecture, the idea presented in this paper looks much further. An approach for a new identity is introduced that describes a machine or a service neither by technical details nor addresses but by the needs they may satisfy. The new human oriented identity management, by focusing on the user's view, leads to a convenient and easy service discovery...
This paper reviews the XML data model and its associated query language within the context of a parallel computing environment. It examines several techniques for structuring and storing XML data across the different parallel nodes. In addition, this paper develops a number of algorithms suitable for processing a certain class of Xqueries, namely, the containment queries, against the parallel XML...
As the wireless technology evolves into the third generation (3G), more bandwidth is available. Because higher bandwidth guarantees better QoS, multimedia services on mobile phones boom, such as video telephony, video share, mobile phone TV, etc. However, data services other than Email and WAP Explorer are not as popular as multimedia services. One possible reason is that there is no unified platform...
This paper is presenting progress status of our project named as emotion based reasoning for constructing a virtual emotional interactive human model. It is based on a person model, whose emotional characteristic been extracted from his work and other physiological, observations. A prototype of the system has been constructed for such experiment and based on famous Japanese writer namely Miyazawa...
Institute of Computer Science of Masaryk University is working on the field of supporting medicine multimedia data transport archiving and processing more than ten years. Since first steps like transport of ultrasound and CT images across private fibre optics network these activities have grown up to regional PACS archive. Today more and more hospitals are participating on this project know under...
In this paper we introduce a new dynamic document adaptation technique for mobile devices. Handheld interfaces most likely invite a goal-directed kind of use - not only because of the limited interaction mechanisms of such devices, but also because of the situations in which they are used. We will explain how the context profile and the user profile can be used, in the first step, to automatically...
This paper aims to determine the measurements for the EMF of some appliances for a healthy human subject including a variety of ELF and RF ranges and to detect the Hot Spot distance and time dependent. Two alternative methods are used for measuring the electromagnetic field and are compared with each other. The first method is by using a cell sensor device to obtain the relation between power densities...
Constructing max-heap-form overlay governed by node gain scores (NGSs), earned from requested bandwidth discrepancy ratio (BDR) with respect to available bandwidth, and latency discrepancy ratio (LDR) between the nodes and the source, reduces induced packet loss caused by schemes neglecting these parameters in constructing the tree. This proposal positions nodes using NGSfunction governed by available...
