The automated deduction and model checking communities have developed techniques that are impressively e ective when applied to suitable problems. However, these problems seldom coincide exactly with those that arise in formal methods. Using small but realistic examples for illustration, I will argue that e ective deductive support for formal methods requires cooperation among di erent techniqu...

one of the main requirements for providing software security is the enforcement of access control policies, which is sometimes referred to as the heart of security. the main purpose of access control policies is to protect resources of the system against unauthorized accesses. any error in the implementation of access control policies may lead to undesirable outcomes. hence, we should ensure th...

In this research, first of all, the existing problems in fragmentation measurement are reviewed for the sake of its fast and reliable evaluation. Then, the available methods used for evaluation of blast results are mentioned. The produced errors especially in recognizing the rock fragments in computer-aided methods, and also, the importance of determination of their sizes in the image analysis ...

understanding of the runoff generation processes is important in understanding the magnitude and dynamics ofgroundwater discharge. however, these processes continue to be difficult to quantify and conceptualize. in this study,two digital filter based separation modules, the recursive filtering method (rdf) and a generalization of therecursive digital filter (grdf) were1991–2002 in the hableh ro...

PVS stands for \Prototype Veriication System." It consists of a speciication language integrated with support tools and a theorem prover. PVS tries to provide the mechanization needed to apply formal methods both rigorously and productively. This tutorial serves to introduce PVS and its use in the context of hardware veriication. In the rst section, we brieey sketch the purposes for which PVS i...

HOL(y)Hammer is an online AI/ATP service for formal (computer-understandable) mathematics encoded in the HOL Light system. The service allows its users to upload and automatically process an arbitrary formal development (project) based on HOL Light, and to attack arbitrary conjectures that use the concepts defined in some of the uploaded projects. For that, the service uses several automated re...

Challenges related to automated driving are no longer focused on just the construction of such vehicles (AVs), but in assuring safety their operation. Recent advances Level 3 and 4 autonomous have motivated more extensive study guarantees complicated AV maneuvers, which aligns with goal ISO 21448 (Safety Intended Functions, or SOTIF), i.e. minimizing unsafe scenarios both known unknown, as well...
