this research was aimed to investigate the condition of the existing roads and designing road network based on forest management plan at armardah, baneh. using analytical hierarchy process (ahp) method, the important layers of slope, aspect, forest type and distance to villages and resorts, were weighted and ranked. maps were produced to weighted layers generated in gis to find suitable regions...

Peer-to-peer (P2P) botnets have recently become serious security threats on the internet. It is difficult to detect the propagation of P2P botnets by isolated monitoring on individual machines due to its decentralised control structure. In this paper, we propose a contact tracing chain-based framework to detect and block P2P botnets by tracing contact behaviours among peers. In the proposed fra...

This work presents threshold tracing schemes. Tracing schemes trace the source of keys which are used in pirate decoders for sensitive or proprietary data (such as pay-TV programs). Previous tracing schemes were designed to operate against any decoder which decrypts with a nonnegligible success probability. We introduce threshold tracing schemes which are only designed to trace the source of ke...

In the last years, the well known ray tracing algorithm gained new popularity with the introduction of interactive ray tracing methods. The high modularity and the ability to produce highly realistic images make ray tracing an attractive alternative to raster graphics hardware. Interactive ray tracing also proved its potential in the field of Mixed Reality rendering and provides novel methods f...

In this paper we present several performance and quality enhancements to classical sphere tracing: First, we propose a safe, over-relaxation-based method for accelerating sphere tracing. Second, a method for dynamically preventing self-intersections upon converting signed distance bounds enables controlling precision and rendering performance. In addition, we present a method for significantly ...

Workžow-centric tracing captures the workžow of causallyrelated events (e.g., work done to process a request) within and among the components of a distributed system. As distributed systems grow in scale and complexity, such tracing is becoming a critical tool for understanding distributed system behavior. Yet, there is a fundamental lack of clarity about how such infrastructures should be desi...

In Crypto’99, Boneh and Franklin proposed a public key traitor tracing scheme [1], which was believed to be able to catch all traitors while not accusing any innocent users (i.e., full-tracing and errorfree). Assuming that Decision Diffie-Hellman problem is unsolvable in Gq, Boneh and Franklin proved that a decoder cannot distinguish valid ciphertexts from invalid ones that are used for tracing...
