Low response time context awareness through extensible parameter adaptation with ORCA

Ubiquitous computing applications or widespread robots interactions execute in unforeseen environments and need to adapt to changeful available services, user needs, and variations of the environment. Context-awareness ability addresses such a need, enabling, through adaptation rules, applications to react to the perceived dynamic variations. Responses to adaptation have to be quick enough to maximize the time during which the application is coherent with its environment. Adaptation rules, associating variations of the environment to application reactions, are usually established at design time. However, in unforeseen and partially anticipated environments, we claim that adaptation rules have to be dynamically extensible to match previously unexpected variations. Our approach enables rule composition and ensures a deterministic result. We propose to use parameter adaptation to quickly respond to environmental variations and dynamic compositional adaptation to provide extensibility to the parameter adaptation. To foster even lower response times, we internalize context-awareness processing and decision into the application.

Think Small for Big Impact

Molecular engineering has emerged as an approach to integrate molecular‐level science and engineering to develop solutions to urgent societal problems. It aims to bring together molecular design—both rational and evolutionary, chemistry, and assembly to achieve new (bio)materials and device functionality. Molecular engineering also aims to bring researchers together to create new research interfaces between computation, machine learning, (bio)chemical synthesis and technology creation perspectives to accelerate new technologies for water and energy resources, information security, and human health.     

Factory cycle-time prediction with a data-mining approach

An estimate of cycle time for a product in a factory is critical to semiconductor manufacturers (and in other industries) to assess customer due dates, schedule resources and actions for anticipated job completions, and to monitor the operation. Historical data can be used to learn a predictive model for cycle time based on measured and calculated process metrics (such as work-in-progress at specific operations, lot priority, product type, and so forth). Such a method is relatively easy to develop and maintain. Modern data mining algorithms are used to develop nonlinear predictors applicable to the majority of process lots, and three methods are compared here. They are compared with respect to performance in actual manufacturing data (to predict times for both final and intermediate steps) and for the feasibility to maintain and rebuild the model.

Design and Performance Evaluation of a Remote Catheter Navigation System

A novel remote catheter navigation system has been developed to reduce physical stress and irradiation to the interventionalist during fluoroscopic X-ray guided catheter intervention. The unique teleoperated design of this system allows the interventionalist to apply conventional axial and radial motion, as used in current practice, to an input catheter placed in a radiation-safe location to control a second catheter placed inside the procedure room. A catheter sensor (used to measure motion of the input catheter) and a catheter manipulator (used to manipulate the second catheter) are both presented. Performance evaluation of the system was assessed by first conducting bench-top experiments to quantify accuracy and precision of both sensed and replicated motion, and then conducting two experiments to evaluate the latency from sensed to replicated motion. The first study consisted of replicating motions of prescribed motion trajectories, while the second study utilized eight operators to remotely navigate a catheter through a normal carotid model. The results show the system has the ability to sense and replicate motion to within 1 mm and 1^deg in the axial and radial directions, respectively. Remote catheter manipulation was found to be operator dependent and occurred under 300 ms. Future applications of this technology are then presented.

ITU-T initiatives on climate change

It is estimated that ICTs contribute around 2 percent of global greenhouse gas emissions. These percentages are likely to grow as ICTs become more widely available. At the same time, ICTs can be a major linchpin in efforts to combat climate change and serve as a potent cross-cutting tool to limit and ultimately reduce GHG emissions across economic and social sectors. This article looks at the potential role ICTs play at different stages, from contributing to global warming to monitoring it, to developing long-term solutions to mitigate its effects, both directly in the ICT sector and in other sectors such as energy, transport, buildings, and finally to helping adapt to its effects. The article addresses the efforts made by the ITU and its membership to develop new climate-friendly technologies.

Three hundred-mm wafers: a technological and an economical challenge

For the transition from 200- to 300-mm wafers, in addition to the technological challenges, there is the equivalent cost challenge to be met. The ultimate target is cost parity per unit area of silicon between 200 and 300 mm. The major blocking point to be cleared appears to be crystal pulling. The question of cost of crystal pulling is mainly related to the large crystal weights (>300 kg) and to the issue of crystal defects (crystal originated pits (COPs); voids in the Si crystal) generated by crystal pulling. An alternative route to address the defect problem is to use epitaxy to create a defect-free layer of Si for the active device regions. Close co-operation between wafer manufacturers and users is absolutely necessary to address these key issues. Furthermore, to contain cost, wafer makers and device manufacturers have to work together intensively to implement standardisation wherever possible and to avoid cost driving overspecifications (e.g. for front and backside particles or flatness).     

Quasi-periodic spatiotemporal filtering.

This paper presents the online estimation of temporal frequency to simultaneously detect and identify the quasiperiodic motion of an object. We introduce color to increase discriminative power of a reoccurring object and to provide robustness to appearance changes due to illumination changes. Spatial contextual information is incorporated by considering the object motion at different scales. We combined spatiospectral Gaussian filters and a temporal reparameterized Gabor filter to construct the online temporal frequency filter. We demonstrate the online filter to respond faster and decay faster than offline Gabor filters. Further, we show the online filter to be more selective to the tuned frequency than Gabor filters. We contribute to temporal frequency analysis in that we both identify ("what") and detect ("when") the frequency. In color video, we demonstrate the filter to detect and identify the periodicity of natural motion. The velocity of moving gratings is determined in a real world example. We consider periodic and quasiperiodic motion of both stationary and nonstationary objects.     

Lorsque la stratégie du grain de sable et la conformité aux normes freinent ľinnovation

For a company, information and communication system is a product of divergent rationalities which come to clash. Dissimilar logic leads to diverging projects : one focused on information aims to integrate and control its processing and flow rate, the other prefers to look at communication as a vector of working together among peers. However beyond these conflicts appears a factor of coherence and cohesion which ultimately helps the rationalities to join. A management able to combine integration of wage earners by identifying the objectives of the company and individualism (information systems is a vector of such a strategy). The goal is to avoid a major risk in form of mass action. The remaining question turns about the ability for innovation allowed to wage-earners in a company driven by standards and believes, in fact ideology. Sticking to standards, in other words conformity seems to leave out marginal handling and conflicting situation sources of innovative spirit.
