We present a static analysis algorithm for detecting security vulnerabilities in PHP, a popular server-side scripting language for building web applications. Our analysis employs a novel three-tier architecture to capture information at decreasing levels of granularity at the intrablock, intraprocedural, and interprocedural level. This architecture enables us to handle dynamic features of scrip...

This paper first lists some features of scientific analysis tools that are important for effective analysis in CPSEs (collaborative problem solving environments). Next, design criteria for achieving these features are presented. Then requirements for a CPSE architecture to support these design criteria are listed. Some proposed architectures for CPSEs are reviewed and their capabilities to supp...

Conventional collaborative filtering(CF) recommendation applies the user-based centralized architecture. This architecture has some problems of sparsity and scalability, in addition to not fit the current popular P2P architecture. Therefore, this paper proposes a distributed model to implement the CF algorithm by maintaining the user’s record information distributedly in each nodes throughout t...

In this paper we present a P2P file-sharing architecture optimized for mobile networks. We discuss the applicability of current P2P techniques for resource access and mediation in the context of 2.5G/3G mobile networks. We investigate a mobile P2P architecture that is able to reconcile the decentralized operation of P2P file sharing with the interests of network operators, e. g. control and per...

I present a domain-specific architecture targeted for a real-world version of the Blocks World domain called “Real” Blocks World. The architecture design attempts to include the best features of several popular Agent Architecures, while mitigating their weaknesses. Agent functionality is considered in light of environment scenarios, single-agent, and multiagent systems.

Neuroscience-inspired computational elements and architectures are one of the most popular ideas for replacing the von Neumann architecture. In this work, we propose a neuroscience-inspired dynamic architecture (NIDA) and discuss a method for automatically designing NIDA networks to accomplish tasks. We discuss the reasons we chose evolutionary optimization as the main design method and propose...

Enterprise architecture (EA) is a description of an organization from the integrated business and IT perspective intended to facilitate information systems planning. Popular EA frameworks 1, 2 , books 3, 4 and even academic articles 5 suggest that EA provides comprehensive descriptions of the current and future states of an organization as well as a transition roadmap between them. Essentially,...

in this article which deals with the survey and analytic concept of space in vernacular and modern architecture, first the concept of space is explicated generally while it is briefly free of style and orientation. then, it offers explanations of each kind of above mentioned architectures that has been invoked by researchers and intellectuals about art and architecture. then differences of the ...

technical secondary schools are becoming a common type of schools in iran and “architectural drafting” is a popular field provided in it to prepare drafting technicians for design offices. another main purpose can be conceived for these courses and it is to fill the gap between profession of architecture and the society. special teaching method proposed for these courses is valid to pay attenti...
