Planning Approaches

AbstractInspection planning approaches so far have focused on automatically obtaining an optimal set of viewpoints required to cover a given object. While research has provided interesting results, the automatic inspection planning has still not been made a part of the everyday inspection system development process. This is mostly because the plans are difficult to verify and it is impossible to compare them to laboratory-developed plans. In this work, we give an overview of available generate-and-test approaches, evaluate their results for various objects and finally compare them to plans created by inspection system development experts. The comparison emphasizes both benefits and downsides of automated approaches and highlights problems which need to be tackled in the future in order to make the automated inspection planning more applicable.

Abstract This paper describes the investigation of donut-shaped probe marker discolorations found on Al bondpads. Based on SEM/EDS, TEM/EELS, and Auger analysis, the corrosion product is a combination of aluminum, fluorine, and oxygen, implying that the discolorations are due to the presence of fluorine. Highly accelerated stress tests simulating one year of storage in air resulted in no new or worsening discolorations in the affected chips. In order to identify the exact cause of the fluorine-induced corrosion, the authors developed an automated inspection system that scans an entire wafer, recording and quantifying image contrast and brightness variations associated with discolorations. Dark field TEM images reveal thickness variations of up to 5 nm in the corrosion film, and EELS line scan data show the corresponding compositional distributions. The findings indicate that fluorine-containing gases used in upstream processes leave residues behind that are driven in to the Al bondpads by probe-tip forces and activated by the electric field generated during CP testing. The knowledge acquired has proven helpful in managing the problem.

The Future

AbstractThe article examines the increasingly important role played by technology in the domain of public security in Germany, illustrating its effects on social life. In order to illuminate developments that govern the adoption of security technologies and render them in their dependencies comprehensible, we present two plausible and consistent future scenarios for Germany 2035. Following Jasanoff and Kim, these scenarios are theoretically conceived as two competing “sociotechnical imaginaries” which implies different trajectories for shaping the future. In these imaginaries, security technologies condition social change, and vice versa, in a mutually interdependent process. On the basis of current literature in tandem with a structured scenario development process, we condensed the present sociotechnical imaginaries into two tangible future scenarios for the field of public security, illustrating its effects on how we live as a society. Our overarching goal is to identify key factors that will mediate future developments, and, by extension, to facilitate discussion on the type of future we find collectively desirable. The analysis of impact factors resulted in ten key factors that play a crucial role for the use of security technologies and serve as a leverage for shaping the future. Projections of these factors lead to two narrative scenarios “To Be Ahead” and “Turn Back The Clock”.

AbstractThe International Planning Competition (IPC) is a prominent event of the artificial intelligence planning community that has been organized since 1998; it aims at fostering the development and comparison of planning approaches, assessing the state-of-the-art in planning and identifying new challenging benchmarks. IPC has a strong impact also outside the planning community, by providing a large number of ready-to-use planning engines and testing pioneering applications of planning techniques.This paper focusses on the deterministic part of IPC 2014, and describes format, participants, benchmarks as well as a thorough analysis of the results. Generally, results of the competition indicates some significant progress, but they also highlight issues and challenges that the planning community will have to face in the future.

Abstract This paper describes the status of the API project to develop and maintain Risk-Based Inspection (RBI) methodology for application within the petroleum and chemical industry. The original project has now moved from a “development” phase into an “implement and improve” phase. This paper describes the essential features of API RBI, the most recent enhancements, software features, the future direction for the project, and some user experiences. This paper also describes the acceptance of RBI by various API codes and standards, by jurisdictional authorities, and it also describes the development of an API recommended practice on RBI (API RP 580) as well as the development of an ASME standard on RBI.

Zur Verbesserung der derzeit manuellen Entwicklung, werden Methoden zur Simulation von VWF erforscht. Der Fachartikel stellt eine physiksimulationsbasierte Sensitivitätsanalyse des Förderguts bezüglich der Topologie im VWF vor. Die Ergebnisse dieser Analyse dienen als Basis für die Entwicklung eines Verfahrens zur automatischen Generierung von Ordnungsschikanen.   Vibratory bowl feeders (VBF) are the most frequently used systems for automated sorting and feeding of bulk material. To improve the current manual development process, methods for simulation of VBF are researched.

These results provide a basis for the future development of an algorithm for the automated generation of orienting devices.
