In the paper we study popular b-matchings, which in other words are popular many-to-many matchings. The problem can be best described in graph terms: We are given a bipartite graph G = (A ∪H,E), a capacity function on vertices b : A ∪H → N and a rank function on edges r : E → N . A stands for the set of agents and H for the set of houses. Each member of a set of agents a ∈ A has a preference li...

this study evaluates the lifelikeness layers of boroujerdi’s house in kashan as a case study to analyze the houses of islamic period, especially qajar era. why traditional iranian architecture was considered as sustainable architecture? what are the elements included in the traditional architecture to take the most advantage of the least facilities? what elements does the modern architecture la...

In this paper, we propose a novel adaptive dynamic programming (ADP) architecture with three networks, an action network, a critic network, and a reference network, to develop internal goalrepresentation for online learning and optimization. Unlike the traditional ADP design normally with an action network and a critic network, our approach integrates the third network, a reference network, int...

Application sandboxes provide restricted execution environments that limit an application’s access to sensitive OS resources. These systems are an increasingly popular method for limiting the impact of a compromise. While a variety of mechanisms for building these systems have been proposed, the most thoroughly implemented and studied are based on system call interposition. Current interpositio...

In modern FPGA CAD ow, netlist routing on a particular routing architecture is solved in two steps, global routing based on wire bandwidth constraints of the architecture, and subsequent detailed routing based on the ner switching constraints of the architecture. Detailed routing is dif-cult and provably NP-complete in popular 2-D mesh architectures such as the Xilinx 4000 series FPGAs 16]. Cer...

Digital image archival and distribution systems are an indispensable part of the modern digital age. Organizations perceive a need for increased information security. However, conventional image encryption methods are not versatile enough to meet more advanced image security demands. We propose a universal multi-level ROI image encryption architecture that is based on biometric data. The propos...

Disk arrays, or RAIDs, have become the solution to increase the capacity, bandwidth and reliability of most storage systems. In spite of its high redundancy level, disk mirroring is a popular RAID paradigm, because replicating data also doubles the bandwidth available for processing read requests, improves the reliability and achieves fault tolerance. In this paper, we present a new RAID archit...

Location-based social networking services are becoming increasingly popular among the multitude of mobile applications. The new location sharing functionalities made possible by GPS-based mobile phones, however, also raise two main privacy issues: users are typically limited to a only few built-in options that do not support fine-granular or even changing privacy preferences, and location data ...

With WSDL, SOAP and UDDI, Web services are becoming popular with Web application. However, current Web services architecture is confronted with a few intractable problems. We shall give an overview of these problems and current efforts. Finally, we set an eye on the amalgamation of Web services and Grid technologies.

Web development is currently driven by model-view-controller (MVC) frameworks. How has content management adapted to this scenario? This paper reviews content management features in Ruby on Rails framework and its most popular plug-ins. These features are distributed among the different layers of the MVC architecture.
