Active Fault Management in Autonomous Systems Using Sensitivity Analysis

fault location in power distribution networks using matching algorithm

چکیده رساله/پایان نامه : تاکنون روش‏های متعددی در ارتباط با مکان یابی خطا در شبکه انتقال ارائه شده است. استفاده مستقیم از این روش‏ها در شبکه توزیع به دلایلی همچون وجود انشعاب‏های متعدد، غیر یکنواختی فیدرها (خطوط کابلی، خطوط هوایی، سطح مقطع متفاوت انشعاب ها و تنه اصلی فیدر)، نامتعادلی (عدم جابجا شدگی خطوط، بارهای تک‏فاز و سه فاز)، ثابت نبودن بار و اندازه گیری مقادیر ولتاژ و جریان فقط در ابتدای...

Autonomous Management of Virtual Machine Failures in IaaS Using Fault Tree Analysis

Cloud IaaS services bring the novelty of elastic delivery of computational resources in a virtualized form and resource management through easy replication of virtual nodes and live migration. In such dynamic and volatile environments where resources are virtualized, availability and reliability are mandatory for assuring an accepted quality of service for end users. In this context specific fa...

Active Trust Management for Autonomous Adaptive Survivable Systems

Fault Sensitivity Analysis

This paper proposes a new fault-based attack called the Fault Sensitivity Analysis (FSA) attack, which unlike most existing fault-based analyses including Differential Fault Analysis (DFA) does not use values of faulty ciphertexts. Fault sensitivity means the critical condition when a faulty output begins to exhibit some detectable characteristics, e.g., the clock frequency when fault operation...

Active World Model for Testing Autonomous Systems Using CEFSM

This paper describes a model-based test generation approach for testing autonomous systems interacting with their environment (i.e., world). Unlike other approaches that assume a static world with attributes and values, we present and test a dynamic world. We use Communicating Extended Finite State Machine (CEFSM) to illustrate an active world model that describes behaviors of environmental fac...
