This paper presents a low cost and flexible home control and monitoring system using an embedded micro-web server, with IP connectivity for accessing and controlling devices and appliances remotely using Android based Smart phone app. The proposed system does not require a dedicated server PC with respect to similar systems and offers a novel communication protocol to monitor and control the ho...

Password is the most commonly used authentication technique to authenticate the users on the web. Password based authentication protocols are susceptible to dictionary attacks by means of automated programs because most of the user chosen passwords are limited to the user’s personal domain. In this paper, we propose an inverse cookie based virtual password authentication protocol that preserves...

With the rapid development of Internet, web applications are becoming more and popular. Many people, groups, organizations, or governments use as a means to share information support business tasks. growing number threats attacks on applications, organizations need effective concept application security. The article is devoted security methods ensuring three-level data protection architecture. ...

Spatial data has now been used extensively in the Web environment, providing online customized maps and supporting map-based applications. The full potential of Web-based spatial applications, however, has yet to be achieved due to performance issues related to the large sizes and high complexity of spatial data. In this paper, we introduce a multiresolution approach to spatial data management ...

In this note we show with an analytical counterexample that the expected delay cost for a G/G/1 queue is not necessarily convex in the arrival rate as sometimes claimed in the literature. We can prove, however, that the total expected delay cost rate is convex in the arrival rate. This cost rate is often of interest when designing queueing systems. Mathematics: Convexity. This note shows that t...

BACKGROUND Chemozart is a 3D Molecule editor and visualizer built on top of native web components. It offers an easy to access service, user-friendly graphical interface and modular design. It is a client centric web application which communicates with the server via a representational state transfer style web service. Both client-side and server-side application are written in JavaScript. A co...

Heterogeneity and interoperability of Web data sources represent the current key issue in Web information extraction and integration. Warehouse approach and virtual approach are the common approaches adopted to integrate heterogeneous Web data sources. However, few analytic model and cost model were developed to measure and assess the efficiency and effectiveness of either approach or a combina...

The integration of four design attributes (componentcost, quality, function, and technology) streamlines product design by providing a multilateral view to designers that leads to cost savings in the supply chain. Since the existing information infrastructure, based on server-side components for these design attributes, does not provide interoperable Web interfaces or semantic service descripti...
