We study the optimization of the expected number of bytes that must be transferred by a Web server when a user visits one of its pages. Given a Web site, we want to find an assignment of hotlinks (shortcuts) that minimizes the expected data transfer, i.e., the average amount of bytes to be downloaded in order to reach one of its pages. We propose an optimization algorithm and perform simulation...

In the online metric matching problem, there are servers on a given space and requests one-by-one. The task of an algorithm is to match each request immediately irrevocably with one unused servers. this paper, we pursue competitive analysis for two variants problem. first variant restriction where server placed at positions, which denoted by OMM([Formula: see text]). We show that simple greedy ...

“Machine learning as a service” (MLaaS) in the cloud accelerates adoption of machine techniques. Nevertheless, externalization data on raises serious vulnerability issue because it requires disclosing private to provider. This paper deals with this problem and brings solution for K-nearest neighbors (k-NN) algorithm homomorphic encryption scheme (called TFHE) by operating end-to-end encrypted w...

One of the basic combinatorial optimization problems is the assignment problem that deals with assigning jobs to individuals. In traditional assignment problems, n jobs usually assign to n individuals such that the total cost is minimized or the total profit is maximized. However, in numerous real-life applications, various attributes could be considered in assignment problems while data (obj...

We study the problem of applying adaptive filters for approximate query processing in a distributed stream environment. We propose filter bound assignment protocols with the objective of reducing communication cost. Most previous works focus on value-based queries (e.g., average) with numerical error tolerance. In this paper, we cover entity-based queries (e.g., nearest neighbor) with non-value...

Model-Driven Software Development (MDSD) can be used to enhance developing and maintaining web applications. Furthermore, security plays a crucial role in the area of web applications. A seamless integration of access control and modeling web applications becomes important. This work introduces model-driven integration of security concerns into the development life cycle of web applications. In...

BACKGROUND Identification of negation in electronic health records is essential if we are to understand the computable meaning of the records: Our objective is to compare the accuracy of an automated mechanism for assignment of Negation to clinical concepts within a compositional expression with Human Assigned Negation. Also to perform a failure analysis to identify the causes of poorly identif...

we consider an m/g/1 queue with regular and optional phase vacation and withstate dependent arrival rate. the vacation policy is after completion of service if there are no customers in the system, the server takes vacation consisting of k -phases, each phase is generally distributed. here the first phase is compulsory where as the other phases are optional. for this model the supplementary var...

This paper presents Free Parking System (FPS), a system for assigning free curbside parking spaces to drivers in the cities. FPS has two components: a mobile app running on the drivers’ smart phones that submits parking requests and guides drivers to their parking spaces, and a server that manages the parking assignment process. Unlike existing parking systems, FPS is cost-effective as it does ...
