When planning an intervention on a complex experiment like ATLAS, the detailed knowledge of the system under intervention and of the interconnection with all the other systems is mandatory. In order to improve the understanding of the parties involved in an intervention, a rule-based expert system has been developed. On the one hand this helps to recognise dependencies that are not always evident and on the other hand it facilitates communication between experts with different backgrounds by translating between vocabularies of specific domains. To simulate an event this tool combines information from different areas such as detector control (DCS) and safety (DSS) systems, gas, cooling, ventilation, and electricity distribution. The inference engine provides a list of the systems impacted by an intervention even if they are connected at a very low level and belong to different domains. It also predicts the probability of failure for each of the components affected by an intervention. Risk assessment models considered are fault tree analysis and principal component analysis. The user interface is a web-based application that uses graphics and text to provide different views of the detector system adapted to the different user needs and to interpret the data

While, in recent years, the progress of the science of electricity has been very rapid, few investigations have been made in the old province of frictional electricity. It cannot be doubted, however, that the laws connecting electricity with friction, and with the nature of the substances rubbed, are of great importance; and the acquisition of more detailed knowledge in this department may throw some light on the still imperfect theory of the voltaic cell. Several electricians have expressed an opinion that the development of electricity by friction is only a modification of the development of electricity by contact–that friction is contact in which the number of points which come together is increased by sliding the one substance over the other. But whether friction is a form of contact, or contact a form of friction, or the two co-ordinate to one another, it is interesting to inquire whether the metals can be arranged in an electro-frictional series similar to the electro-contact series; and if so, to observe the relation of the former to the latter.

Designing reliable Web-based courseware systems is not trivial. Courseware authors need to allow as much flexibility in navigating through the system as possible on the one hand, and to ensure the satisfaction of properties and constraints in the system on the other. The problem is aggravated with facilities like Java applets which incorporate dynamic behaviour into the information structure. These issues motivate the need for designing such systems through rigorous modelling and analysis. We propose a scheme using a formal method called the Calculus of Communicating Systems (CCS) to unify the modelling of the courseware based on its navigational structure, semantics and dynamic components. Properties like ordering constraint, reachability and coverage constraint can be answered after a model is extracted from the implementation. Besides, our approach can be extended to assist in the design phase of the construction process, just like what computer-aided software engineering (CASE) tools do. A hypothetical example is used throughout the chapter as an illustration.

The One

This chapter examines the implications the turn-taking approach for our understanding of early modern performance practices. On the one hand, Shakespearean dialogue is full of subtle effects of timing and sequence that would seem to call for careful rehearsal and a detailed knowledge of the script. On the other hand, everything we know about early modern theatre suggests it was performed with minimal rehearsal by actors who did not necessarily know when, or from where, their next cue would arrive. This apparent mismatch I call ‘the performability gap’. The question is how it can be bridged. The explanation provided by Simon Palfrey and Tiffany Stern—that Shakespeare’s plays are designed to make artistic capital from their own under-rehearsal—does not entirely solve the problem. The second half of the chapter speculates about how else we might account for the gap.

The Historical Development of Idealism and Realism

The principal component elements in the progressive struggle of the historical development of Idealism and Realism were, “Hellenism ” on the one side, and a misunderstood “Christianity” on the other. Hellenism, in spite of its Platonic idealism, still represented the embodiment of the forces of nature, while Christianity strove for the spiritualization and “disembodiment” of all phenomena, and of man himself. This tendency, which took its origin in the ascetics of India and the mystic priests of Egypt, produced that grand and mighty phenomenon of monasticism, the aim of which was to retire from the world, and to attain a state of conscious blissfulness in this life. Monks were said to be able to dispense with food, to float in the air, to have intercourse with angels and sometimes also with demons, to see with bodily eyes the glories of the saints, to pierce the future, and to lead an incorporeal life in spite of their living bodies. An EgyptoBuddhistic Platonism began to sway the minds of Christian believers, and they thronged in tens of thousands to people deserts and woods, mountains and sea-shores, with anchorets, pillar saints, coenobites, and hermits. Humanity was apparently altogether absorbed in a spiritualized stoicism, applying Epicurus's principles to an ascetic life, finding joy, contentment.

This article introduces the art historical method of functional deixis into the study of material culture in anthropology. Functional deixis begins with a thorough empirical description of communicative effects—visual and embodied—produced by a material thing on the beholder. It then proceeds by tending to a kind of formalisation that enables us, on the one hand, to sharpen our intuitive reaction to the thing and, on the other, to obtain detailed knowledge about the ways material things produce significance. Here, the method is applied to a tatanua mask originating from present-day Papua New Guinea and currently housed at the Grassi Museum für Völkerkunde in Leipzig, Germany. Based on a thick description, we propose an in-depth interpretation of the mask as a complex response to a fundamental injury, articulating a symbolic expression of grief (left side) with an iconic expression overcoming grief (right side) after a passage through a real word expressed through the front of the mask. In doing so, the article offers a tool to study with rather than a text to read off.

While developing a Web-based travel planning system, the necessity to implement a mobile component has been identified. Such a conception is aimed at a comprehensive support of a workflow that enables users to plan a trip in advance using the Web-based application, but to modify the original plan wherever and whenever they want while carrying out the journey. Within both components, Point-of-Interest (POI) plays a significant role to determine a tour. It is one claim of this chapter that the relevance of POI is dependent on the perspective of a user. As a consequence, the originally used POI database was replaced by a POI ontology which promised to support the workflow more comprehensively. This conceptual change raised several questions concerning the domain dependence of the POI ontology on the one side and universal aspects of the ontology on the other.

Abstract A new method and device for temperature measurement are presented. The method reduces the measurement of the unknown temperature to the solving of an optimal control problem, using a numerical computer. The device consists of a hardware part including some conventional transducers and a software one. The problem of temperature measurement, according to this method, is mathematically modelled by means of the one-dimensional heat equation, describing the heat transfer through the device. The principal component of the device is a rod. The variation of the temperature which is produced near one end of the rod is determined using some temperature measurements in the other end of the rod, the mathematical model and a type of gradient algorithm. This device works as an attenuator of high temperatures and as an amplifier of low temperatures.

This article analyses processes of change undergone by Spanish medium-sized cities during 1981–2011 on the one hand, and 2000–2018 on the other, as they are different sources. We established a classification to show the importance of this type of city starting from the hypothesis that the process is a generalised one in which they behave according to their position in the territory. The dynamics of change are predominantly associated with contexts of economic expansion. The typology was generated based on population and housing variables, which synthesise the role played by economic activity in each city. Additional methodologies were used: firstly, the bibliography on medium-sized cities in different social and cultural contexts was reviewed; secondly, statistical data were selected, compiled and processed using multivariant statistical analyses, and the results mapped. A study of 133 cities was carried out and absolute values and variation rates used to understand the processes of change. As a result, seven representative groups were obtained. The conclusions of the study can be corroborated by different sources.

This paper proposes a solution to facilitate maintenance activities associated with stand-alone solar photovoltaic installations in our developing countries. The autonomous photovoltaic solar installation is not connected to the electricity distribution grid. It meets the electricity needs on the one hand, of those who are too far away and who do not have access to the distribution grid. On the other hand, those who wish to overcome the constraints of connection to the electrical distribution grid. Our work focuses on the capitalization of knowledge in maintenance activity. The goal is to propose a model capable of helping maintenance technicians during their interventions by providing them with knowledge elements that will be drawn from a knowledge base. This knowledge base is built from the knowledge collected during previous maintenance activities in a given solar photovoltaic installation.

The effectiveness of solution-focused working in coaching and consultancy The effectiveness of solution-focused working in coaching and consultancy C. Visser & R. Butter, Gedrag & Organisatie, volume 21, March 2008, pp. 35-55 Until now, little research has been done on the effectiveness of organizational consultancy and coaching. This study aims to make a contribution to the knowledge development in this area. A web-based questionnaire was administered with 158 clients of coaches and organizational consultants. Through this questionnaire, the relation was studied between, on the one hand, the way of contracting and the approach followed, and on the other hand the effectiveness of the project. One of the most striking conclusions is that a client-led way of working – which is one of the important characteristics of the solution-focused approach – in which the client directs the process while the advisor responds flexibly, is strongly associated with success. The article closes with some practical suggestions for advisors and for follow-up research.
