Safety Assessment of Collaborative Robotics Through Automated Formal Verification

An Automated Formal Verification Flow for Safety Registers

Automotive microcontrollers support an increasing number of safety applications and include various safety mechanisms in order to meet the ISO 26262 standard. Derivatives of product families address different market segments and customers with individual safety requirements. Thus flexibility is needed to adjust the overhead introduced by extra safety circuitry to the actual configurations and s...

Formal Verification and Safety Assessment of a Hemodialysis Machine

Design and formal verification of DZMBE+

In this paper, a new broadcast encryption scheme is presented based on threshold secret sharing and secure multiparty computation. This scheme is maintained to be dynamic in that a broadcaster can broadcast a message to any of the dynamic groups of users in the system and it is also fair in the sense that no cheater is able to gain an unfair advantage over other users. Another important feature...

Risk Assessment in Collaborative Robotics

Problems and Objectives. In Human-Robot Collaborative (HRC) applications, operators and robots work in a common space. Their close interactions increase the likelihood of direct physical contacts either due to the intrinsics of the operations (e.g., tools, motions, etc) or behavior of the operator (e.g., mistakes, misuses, instruction misunderstanding, etc). Unintended physical contacts may lea...

Automated Formal Verification of Model Tranformations

As the Model Driven Architecture (MDA) relies on complex and highly automated model transformations between arbitrary modeling languages, the quality of such transformations is of immense importance as it can easily become a bottleneck of a model-driven design process. Automation surely increases the quality of such transformations as errors manually implanted into transformation programs durin...
