In this paper, we present a WItness based Data priority mEchanism (WIDE) for vehicles in the vicinity of an accident to facilitate liability decisions. WIDE evaluates integrity data generated by these vehicles, called witnesses, event assure reliability be used making decisions and ensure that such are received from credible witnesses. To achieve this, introduces two-level assessment end-to-end...

With its characteristics of decentralization, security, data traceability, and tamper-resistance, the blockchain has been widely used in various domains. Considering difference performance devices, light client is proposed so that devices without ability to store a full copy can also participate transactions. However, communicate with nodes verify authenticity transaction which brings some exte...

Vehicles on the road, where an Intelligent Transportation System (ITS) is built, can share a lot of traffic information and drive more safely efficiently through data sharing. Since incorrect misleads vehicles causes confusion in traffic, vehicular trust model needed to check message’s trustworthiness while considering vehicle’s properties protecting its privacy. In this paper, we proposed two ...

objective: the present study aimed to compare the effectiveness of metacognitive therapy (mct) and cognitive-behavior therapy (cbt) in treating iranian patients with major depressive disorder (mdd). methods: thirty three outpatients meeting dsm-iv-tr criteria for mdd without any other axis i and ii disorders were randomly assigned to one of three treatment conditions, i.e. mct, cbt and pharmaco...

objective: the purpose of the present study was to compare the efficacy of metacognitive therapy with cognitive therapy on reducing test anxiety and meta-worry among students. methods: the present study is a quasi-experimental research with pre- and post-test design with a control group. study population comprised all female students of tarbiat-modaresuniversity of tehran and sample included 15...

introduction: hearing loss occurs when there is a problem with one or more parts of the ear or ears and causes children to have a delay in the language-learning process. hearing loss affects children's lives and their development. several approaches have been developed over recent decades to help hearing-impaired children develop language skills. auditory-verbal therapy (avt) is one such a...

objective: to determine the effect of group cognitive behavior therapy (cbt) on psychological hardiness and coping strategies of infertile women undergoing assisted reproductive therapy (art). methods: two groups of infertile women who received art consisted of experimental group (15 females) and control group (16 females) were compared. the participants in experimental group received 15 sessio...

Blockchain is built on a peer-to-peer network that relies frequent communications among distributively located nodes. In particular, the consensus mechanisms (CMs), which play pivotal role in blockchain, are communication resource-demanding and largely determine blockchain security bounds (i.e., fault tolerances) other key performance metrics such as transaction throughput, latency scalability....

The Internet of Things (IoT) is vulnerable to leakage private information during data sharing. To avoid this problem, access control and secure sharing have been introduced in IoT; however, many challenges are faced because centralized single delegator selection. Additionally, blockchain integrated into IoT enhance the security environment. For that purpose, research proposes dynamic using (DSA...
