A vehicular network is expected to empower all aspects of the intelligent transportation system (ITS) and aim at improving road safety traffic efficiency. In view fact that spectrum scarcity becomes more severe owing increasing number connected vehicles, implying sensing technology in network, i.e., cognitive has emerged as a promising solution provide opportunistic usage licensed spectrum. How...

Traditional deep learning methods are suboptimal in classifying ambiguity features, which often arise noisy and hard to predict categories, especially, distinguish semantic scoring. Semantic scoring, depending on logic implement evaluation, inevitably contains fuzzy description misses some concepts, for example, the ambiguous relationship between normal probably always presents unclear boundari...

Neutrophils are the most abundant immune cell in circulation. However, due to a number of technical challenges for researchers, including neutrophil's short lifespan and difficulties with preservation, they often discarded during blood processing thus ignored cohort studies. As such, contribution neutrophils disease their involvement mechanisms is less explored compared other types. Systemic lu...

We investigate the descriptional complexity of limited propagating Lindenmayer systems and their deterministic and tabled variants with respect to the number of rules and the number of symbols. We determine the decrease of complexity when the generative capacity is increased. For incomparable families, we give languages that can be described more efficiently in either of these families than in ...

based on a general rule in civil liability, external causes limits or excludes the liability of defendant. however, the question is that whether it is possible to applied the general rule when there are compulsory liability insurances? this paper is intended to study the subject-matter regarding traffic accidents (as one of the anticipated cases of compulsory insurances) in iranian and french l...

Trust transitivity is a common phenomenon embedded in human reasoning about trust. Given a specific context or purpose, trust transitivity is often manifested through the humans’ intuition to rely on the recommendations of a trustworthy advisor about another entity that the advisor recommends. Although this simple principle has been formalised in various ways for many trust and reputation syste...

The central goal of Public Key Infrastructure (PKI) is to enable trust judgments between distributed users. Although certificates play a central role in making such judgments, a PKI’s users need more than just knowledge of certificates. Minimally, a relying party must able to locate critical parameters such the certificate repositories and certificate validation servers relevant to the trust pa...

With this construction we show that MD5 collisions can be crafted easily in such a way that the principles underlying the trust in Public Key Infrastructure are violated. In particular we find it worrying that from one certificate alone it cannot be determined whether another, different certificate may exist with the same signature. For the second certificate the issuing Certification Authority...
