With the increasing demands for cloud resources, the task to keep it balanced with supply at all times becomes especially challenging. However, most of existing mechanisms focus on auction-based allocation of cloud resources rather than balancing the demands for cloud resources. In order to deal with this problem, this paper presents the problem of cloud resources consumption shifting between two...
Human resource allocation problem is a social problem that has been studied extensively. Aimed at the allocation of human resources, this paper proposed a reasonable mechanism of human resource allocation in which human resource allocation is regarded as the formation of multiple teams. First, tasks submit the skills that they require to the mechanism, and then the mechanism sorts the tasks in a descending...
In view of that the existing auction mechanism cannot effectively allocate cloudlet resource, which leads to a low resource utilization rate and social welfare. In this paper, we design a truthful greedy mechanism (TGM) to coordinate the auction of mobile users (buyers) and cloudlets (sellers). TGM consists of the greedy allocation algorithm based on buyer preferences and pricing mechanism, and improves...
Wound area changes over multiple weeks are highly predictive of the wound healing process. Big data processing is considered as one of the main solutions for it. We usually analysis the images of wound bed. Unfortunately, accurate measurements of wound area changes are difficult. In this paper, we propose a novel level set model (LSM) for pre-processing the intensity inhomogeneity images before encoder...
With the rapidly growing demands for cloud resource, the task to keep it balanced with supply at all times becomes especially challenging. However, most of existing mechanisms focus on auction-based allocation of cloud resource rather than balancing the demands for cloud resource. In order to address this issue, we formulate the problem of cloud resource consumption shifting between two different...
In the model of partnership formation, every agent is in hot pursuit of maximizing his own utility. Doft Talman and Zaifu Yang have revealed the necessary condition of the existence of partnership equilibrium, however, the methods of how to compute the equilibrium are not given. The paper presents a method to compute the partnership utility equilibrium based on socially optimal assignment Firstly,...
Market mechanism constitutes an efficient scheme for the allocation of cloud-based computing resources with the view of virtual machines. However, most of the existing mechanisms commonly use fixed price model and ignore flexible price model for the cloud providers. In this paper, we formulate the problem of virtual machine allocation in clouds as a combinatorial auction problem and propose a mechanism...
It is critical of self-adaptive software system to monitor all kinds of information in real-time and obtain relevant data of the system to make the system can adjust automatically when necessary. In order to cope with the current market needs and rapidly changing environment, and combine the Web services with self-adaptive software systems perfectly, we proposed a monitoring and prediction model for...
With the rapid grows of cloud-based internet application, a need for efficient resource allocation, load balance and cost management increases. In this paper, we propose a group-auction based mechanism for the cloud instance market to efficiently allocate resources. In the market system, resource providers offer resources in the form of virtual machine. Users submit their bids. The proposed system...
Program comprehension is one of the most frequently performed activities during software maintenance and evolution. In order to facilitate program comprehension, a variety of graphical models have been proposed in software engineering community to construct relationships between program elements. These graphical models are mostly used for understanding the system based on structural syntax dependencies...
In this paper, we extend the idea of noise shaping for dual-tree complex wavelet transform (DCWT) image coding to a perceptual-based noise shaping. In classical noise shaping, the spatial error information is compensated by adding it back into the whole DCWT domain, which allows the retained to coefficients have better capability to approximate the original image. The proposed perceptual noise shaping...
In order to achieve an efficient allocation in price interval, this paper allows bidders to present their demands list on all items so as to promote the possibility to be allotted an item and generate the farthest price ascending under real demands. We propose a concept named matrix of demand strength which is yield by a multi-price ascending simultaneously, and, based on this matrix, an allocation...
This paper describes the results of the OIIETM (Ontology-based Intelligent Interactive Electronic Technology Manual) project, as well as the method of constructing a knowledge-based intelligent system from the text of technology manual. Considering the complexity of domain knowledge and the ill-structured representation of technology manual, this paper suggests the architecture of OIITEM system, and...
Coordination is a vital aspect of any type of interaction between computer agents in open distributed systems such as the Web. As distributed systems become more ubiquitous, autonomous and complex, the need to ground them on common data model grows stronger. In particular, Semantic Web services are based on synchronous message exchange, thus being incompatible with the REST architectural model of...
Internet provides a fertile medium for new breeds of computer viruses. Many people who have access to a wealth of information via Internet are attacked by more computer viruses than they can effectively process. We present a dynamic computer virus detection model that can detect known viruses and previously unknown viruses to prevent information systems from damage. This model is inspired by biological...
The researches of Web service fasten on composition process, and are lack of the formalized description on dynamic attributes of service component itself. Aiming to these, a new dynamic and concurrent model of Web service component is presented. Firstly, this paper analyzes the process of state transition of service component under certain actions, and then depicts the dynamic transition process of...
A difficulty of sharing messages transferred among Web services is absence of common vocabulary, and the semantic organization and description of Web services is an important requirement for enabling the automatic discovery, selection, composition, execution and monitoring of Web services. This paper proposes a model for semantic-based interaction between Web services. The method defined some ontology-based...
