This article concerns the design of Decision Support Systems (DSS) based on a Knowledge Discovery from Data (KDD) process. This process aims at generating a set of software modules; it is iterative and interactive For this reason, it is essential to us to take Human-Computer Interaction principles and models into account in the development of such systems. The interactive decisional system development is currently approached according to two antagonistic approaches. For the first approach, technology is fundamental; the second is "user-centered", placing the human actors in a central position. Although the first approach is still very present in companies, the current tendency "is user-centered ". In this context, we propose an approach which aims at integrating the stages of KDD process in a development model enriched under the human-computer interaction point of view, which is the U-model. Our application context is the fight against the nosocomial infections in the healthcare domain.

Purpose – The problem of robotic co-manipulation is often addressed using impedance control based methods where the authors seek to establish a mathematical relation between the velocity of the human-robot interaction point and the force applied by the human operator (HO) at this point. This paper aims to address the problem of co-manipulation for handling tasks seen as a constrained optimal control problem. Design/methodology/approach – The proposed point of view relies on the implementation of a specific online trajectory generator (OTG) associated with a kinematic feedback loop. This OTG is designed so as to translate the HO intentions to ideal trajectories that the robot must follow. It works as an automaton with two states of motion whose transitions are controlled by comparing the magnitude of the force to an adjustable threshold, in order to enable the operator to keep authority over the robot's states of motion. Findings – To ensure the smoothness of the interaction, the authors propose to generate a velocity profile collinear to the force applied at the interaction point. The feedback control loop is then used to satisfy the requirements of stability and of trajectory tracking to guarantee assistance and operator security. The overall strategy is applied to the penducobot problem. Originality/value – The approach stands out for the nature of the problem to be tackled (heavy load handling tasks) and for its vision on the co-manipulation. It is based on the implementation of two main ingredients. The first one lies in the online generation of an appropriate trajectory of the interaction point located at the end-effector and describing the HO intention. The other consists in the design of a control structure allowing a good tracking of the generated trajectory.

Flow as propounded by Csikszentmihalyi is an extraordinary phenomenon helping people maintaining all-encompassing performance ability often triggers curiosity of whether that particular phenomenon can be replicated time and again amongst all the humans. Well, the answer can be both a YES and a NO. In order to explore the phenomenon, we will explore the principles or laws of the universe and its functioning as propounded by Gurdjieff and draw assertions from the exploration to design applicable understanding in the nature of flow. The understanding of Gurdjieff was based on his search for the truth and the mysteries present within the mystic schools in the East. Much of the spiritual work is based on this basic premise that life propagates itself and the understanding of this phenomenon is self-evident to be propounded in the basic dogmatic revelations of the individual agenda. The fundamental truth about the expectation and reality dilemma about the performance scenario based on the interaction point of view with human and its capacities along with the environmental stimuli often brings around certain understanding about the capacities and performance ability in a certain environmental setup. This particular transcending phenomena and immersion and evolving in the process of working and making extraordinary revolutions in all the spheres of life has been a constant curious case to be solved and debated with the help of yoga, Zen, science, religion, mysticism, and occult culminating from various forms of old age and new age philosophical dimensions engulfed into the spiritual underpinnings. Transcending above one's own physical boundaries to take into to the cosmic vibrations and inculcate the energy field within one's own boundaries helping them to perform and replicate things in finest creativity levels often motivates to explore these phenomena into further details.

When using computer-aided translation systems in a typical, professional translation workflow, there are several stages at which there is room for improvement. The SCATE (Smart Computer-Aided Translation Environment) project investigated several of these aspects, both from a human-computer interaction point of view, as well as from a purely technological side. This paper describes the SCATE research with respect to improved fuzzy matching, parallel treebanks, the integration of translation memories with machine translation, quality estimation, terminology extraction from comparable texts, the use of speech recognition in the translation process, and human computer interaction and interface design for the professional translation environment. For each of these topics, we describe the experiments we performed and the conclusions drawn, providing an overview of the highlights of the entire SCATE project.

In this discussion is intended to explore a philosophical point of view about quantum mechanics, proposing quantum chemistry as neo-science, this philosophical approach to our view is certainly much neglected in many textbooks. The importance of creating new concepts in chemistry and propose new methodological tools motivate to the scientist to create new concepts and interpretations in theoretical chemistry.

The Impact

The term geo-sciences has been used here to include the disciplines geology, geophysics and geochemistry. However, in order to apply geophysics and geochemistry effectively one must begin with a geological model. Therefore, the science of geology should be used as the basis for lunar exploration. From an astronomical point of view, a lunar terrain heavily impacted with meteors appears the more reasonable; although from a geological standpoint, volcanism seems the more probable mechanism. A surface liberally marked with volcanic features has been advocated by such geologists as Bülow, Dana, Suess, von Wolff, Shaler, Spurr, and Kuno. In this paper, both the impact and volcanic hypotheses are considered in the application of the geo-sciences to manned lunar exploration. However, more emphasis is placed on the volcanic, or more correctly the defluidization, hypothesis to account for lunar surface features.

ABSTRACTThe mechanism by which a shepherd satellite exerts a confining torque on a ring is considered from the point of view of a single ring particle. It is still not clear how one might most meaningfully include damping effects and other collisional processes into this type of approach to the problem.

Potential Use

The origin of mica polytypes has long been a challenging problem for crystal- lographers, mineralogists and petrologists. From the petrological point of view, interest in this field arose from the potential use of layer stacking data to furnish further informations about equilibrium and/or kinetic conditions prevailing during the crystallization of the widespread mica-bearing rocks. From the compilation of previous experimental works dealing with the occurrence domains of the various mica "polymorphs" (1Mr, 1M, 2M1, 2M2 and 3T) within water-pressure vs temperature fields, it became clear that most of these modifications should be considered as metastable for a fixed mica species. Furthermore, the natural occurrence of long-period (or complex) polytypes could not be accounted for by phase considerations. This highlighted the need of a more detailed kinetic approach of the problem and, in particular, of the role growth mechanisms of basal faces could play in this crystallographic phenomenon.
