Agents with incomplete knowledge of their actions can either plan around the incompleteness, ask questions of a domain expert, or learn through trial and error. We present and evaluate several approaches to formulating plans under incomplete information, using the plans to identify relevant (goaldirected) questions, and interleaving acting, planning, and question asking. We show that goal-direc...

Yahoo Japan Search Technology (YJST) team participated in the Query Understanding subtask of NTCIR-12 IMine-2. We explored various search log mining techniques to discover subtopics against the given original topics. For Vertical Identification, we trained a Gradient Boosted Decision Tree (GBDT) learner to identify a vertical label to each subtopic using several complex features including topic...

Any change that will influence the system’s safety requirements after we have finished the safety analysis and safety planning for development of safety-critical software will require a change impact analysis. One of the reasons for using Scrum is its declarations to “embrace change”. Using agile development we may add new requirements, change existing requirements and make current requirements...

This paper considers the endogenous formation of an institution to provide a public good. If the institution governs only its members, players have an incentive to free ride on the institution formation of others and the social dilemma is simply shifted to a higher level. Addressing this second-order social dilemma, we study the effectiveness of three different minimum participation requirement...

Failure Mode and Effects Analysis (FMEA) is a widely used dependability and safety technique aiming at systematically identifying failure modes, their causes, their effects, and the countermeasures that could mitigate their impact. Although FMEA has been thought for hardware, its use is also advocated for software (SW-FMEA). However, this involves several major hurdles such as the complexity of...

Signalling, a complex system is one of the most important infrastructures of railway service. The performance of railway signalling system depends on the functioning of a number of subsystems, such as panel, cable, relay, point and point machine, trackcircuit, signal, back indication, point-drive card, signal-drive card, and level crossing gate. Railway signalling system plays an important role...

The Fault Mode Effects and Criticality Analyses (FMECA), describe the impact of identified faults. They form an important category of knowledge gathered during the design phase of a satellite, and are used also for diagnosis activities. This paper proposes their extension, allowing a finer representation of the available knowledge, at approximately the same cost, through the introduction of an ...

While the transition to lead-free electronics, which began nearly a decade ago, is complete for most commercial products, many safety, mission and infrastructure critical systems that were originally exempt from RoHS and WEEE are only now transitioning. For these types of products qualification is very expensive and the consequences of failure can be catastrophic, therefore carefully engineered...

The increase of complexity in aircraft systems demands for enhanced analysis techniques. Methods are required that leverage the burden of their application by reusing existing design and process information and by enforcing the reusability of analyses results allowing early identification of design’s weak points and check of design alternatives. This report elaborates on a method that assumes a...

The cable harness manufacturing industry has been growing in a fast pace during the recent years in India. Cable harnesses are used to link together all the electrical components scattered throughout any electrical equipment. Cable harness manufacturing involves a series of operations which are to be carried out in a proper sequence to make a good quality harness. In real time scenario, high vo...
