    Flat-plate solar array project. Volume 8: Project analysis and integration

    Get PDF
    Project Analysis and Integration (PA&I) performed planning and integration activities to support management of the various Flat-Plate Solar Array (FSA) Project R&D activities. Technical and economic goals were established by PA&I for each R&D task within the project to coordinate the thrust toward the National Photovoltaic Program goals. A sophisticated computer modeling capability was developed to assess technical progress toward meeting the economic goals. These models included a manufacturing facility simulation, a photovoltaic power station simulation and a decision aid model incorporating uncertainty. This family of analysis tools was used to track the progress of the technology and to explore the effects of alternative technical paths. Numerous studies conducted by PA&I signaled the achievement of milestones or were the foundation of major FSA project and national program decisions. The most important PA&I activities during the project history are summarized. The PA&I planning function is discussed and how it relates to project direction and important analytical models developed by PA&I for its analytical and assessment activities are reviewed

    The issues of enterprise growth in transition and post-transition period: the case of Polish 'Elektrim'

    Get PDF
    Case study of Polish company Elektrim illustrates the changing basis of growth of enterprises between the transition and post-transition periods. Elektrim grew primarily through conglomeration in the transition period. After the exhaustion of this mode of growth Elektrim has started to focus on a few core areas (telecoms, cables, energy). The strategic shift to telecommunications has been based on partnerships with foreign firms and it is likely that this will be the pattern in other areas. In this respect, the case of Elektrim shows the importance of internationalisation for the growth of enterprises in CEE. Based on the case study the paper draws several analytical issues: First, Elektrim's shift from conglomeration to focusing suggests that the institutional context, which drives firm strategy in post-socialist economies like Poland, is, perhaps, also changing. Second, in order to grow Elektrim is forced to enter into equity relationships and partnerships like with French Vivendi. This suggests that the possibilities for firm growth in post-socialist economies, like Poland, through generic expansion are still fewer when compared to growth based on mergers & acquisitions or different forms of alliances. Third, Elektrim's relationship with government is complex and refutes the simplified dichotomy of markets vs. governments. This raises the issue of to what extent post-socialist governments operate as a 'compensatory mechanism' on which firms like Elektrim can rely to grow. Fourth, the opening of the CEECs has led to relocations of EU and other MNCs into this region with the result that they are also transferring the oligopolistic competition from EU into new markets. The case of Elektrim shows how CEE companies and goverment regulations become factors in the oligopolistic competition between big EU companies. CEE companies and governments may use this competition to their advantage but also their limited bargaining powers may lead to outcomes unfavourable to them

    On Applicability of Automated Planning for Incident Management

    Get PDF
    Incident management aims to save human lives, mitigate the effect of accidents, prevent damages, to mention a few of their benefits. Efficient coordination of rescue team members, allocation of available resources, and appropriate responses to the realtime unfolding of events is critical for managing incidents successfully. Coordination involves a series of decisions and event monitoring, usually made by human coordinators, for instance task definition, task assignment, risk assessment, etc. Each elementary decision can be described by a named action (e.g. boarding an ambulance, assigning a task). Taken as a whole, the team coordinating an incident response can be seen as a decision-making system. In this paper, we discuss how invaluable assistance can be brought to such a system using automated planning. In consultation with experts we have derived a set of requirements from which we provide a formal specification of the domain. Following the specification, we have developed a prototype domain model and evaluated it empirically. Here we present the results of this evaluation, along with several challenges (e.g uncertainty) that we have identifie

    Training of Crisis Mappers and Map Production from Multi-sensor Data: Vernazza Case Study (Cinque Terre National Park, Italy)

    Get PDF
    This aim of paper is to presents the development of a multidisciplinary project carried out by the cooperation between Politecnico di Torino and ITHACA (Information Technology for Humanitarian Assistance, Cooperation and Action). The goal of the project was the training in geospatial data acquiring and processing for students attending Architecture and Engineering Courses, in order to start up a team of "volunteer mappers". Indeed, the project is aimed to document the environmental and built heritage subject to disaster; the purpose is to improve the capabilities of the actors involved in the activities connected in geospatial data collection, integration and sharing. The proposed area for testing the training activities is the Cinque Terre National Park, registered in the World Heritage List since 1997. The area was affected by flood on the 25th of October 2011. According to other international experiences, the group is expected to be active after emergencies in order to upgrade maps, using data acquired by typical geomatic methods and techniques such as terrestrial and aerial Lidar, close-range and aerial photogrammetry, topographic and GNSS instruments etc.; or by non conventional systems and instruments such us UAV, mobile mapping etc. The ultimate goal is to implement a WebGIS platform to share all the data collected with local authorities and the Civil Protectio

    The end of indefinitely renewable leave of absence in Scotland: the impact of the Mental Health (Patients in the Community) Act 1995

    Get PDF
    The Mental Health (Patients in the Community) Act 1995 restricted leave of absence (LOA) for detained patients in Scotland to 12 months. This study looked at the impact on patients who were affected by this restriction. A total of 266 patients were identified from Mental Welfare Commission records: 194 reached the new maximum, 47 were 'transitional', 16 were on improperly long LOA and 9 were on community care orders (CCOs) following LOA but not maximum LOA. Of this 194, 12 were transferred to guardianship and the remainder became voluntary patients. The responsible medical officers (RMOs) would have liked to renew LOA for 71% of patients. In 90% of cases RMOs renewed LOA to ensure compliance with medication. Patients were significantly more likely to be compliant with medication while on LOA than post-LOA. A minority (28%) were recorded as being involved in 'incidents' post-LOA. There were 37% who were known to have a substance use problem in their management. The results suggest that RMOs may have been conservative in using LOA

    Asteroseismology of massive stars with the TESS mission: the runaway Beta Cep pulsator PHL 346 = HN Aqr

    Full text link
    We report an analysis of the first known Beta Cep pulsator observed by the TESS mission, the runaway star PHL 346 = HN Aqr. The star, previously known as a singly-periodic pulsator, has at least 34 oscillation modes excited, 12 of those in the g-mode domain and 22 p modes. Analysis of archival data implies that the amplitude and frequency of the dominant mode and the stellar radial velocity were variable over time. A binary nature would be inconsistent with the inferred ejection velocity from the Galactic disc of 420 km/s, which is too large to be survivable by a runaway binary system. A kinematic analysis of the star results in an age constraint (23 +- 1 Myr) that can be imposed on asteroseismic modelling and that can be used to remove degeneracies in the modelling process. Our attempts to match the excitation of the observed frequency spectrum resulted in pulsation models that were too young. Hence, asteroseismic studies of runaway pulsators can become vital not only in tracing the evolutionary history of such objects, but to understand the interior structure of massive stars in general. TESS is now opening up these stars for detailed asteroseismic investigation.Comment: accepted for ApJ

    Approaches to the Algorithmic Allocation of Public Resources: A Cross-disciplinary Review

    Full text link
    Allocation of scarce resources is a recurring challenge for the public sector: something that emerges in areas as diverse as healthcare, disaster recovery, and social welfare. The complexity of these policy domains and the need for meeting multiple and sometimes conflicting criteria has led to increased focus on the use of algorithms in this type of decision. However, little engagement between researchers across these domains has happened, meaning a lack of understanding of common problems and techniques for approaching them. Here, we performed a cross disciplinary literature review to understand approaches taken for different areas of algorithmic allocation including healthcare, organ transplantation, homelessness, disaster relief, and welfare. We initially identified 1070 papers by searching the literature, then six researchers went through them in two phases of screening resulting in 176 and 75 relevant papers respectively. We then analyzed the 75 papers from the lenses of optimization goals, techniques, interpretability, flexibility, bias, ethical considerations, and performance. We categorized approaches into human-oriented versus resource-oriented perspective, and individual versus aggregate and identified that 76% of the papers approached the problem from a human perspective and 60% from an aggregate level using optimization techniques. We found considerable potential for performance gains, with optimization techniques often decreasing waiting times and increasing success rate by as much as 50%. However, there was a lack of attention to responsible innovation: only around one third of the papers considered ethical issues in choosing the optimization goals while just a very few of them paid attention to the bias issues. Our work can serve as a guide for policy makers and researchers wanting to use an algorithm for addressing a resource allocation problem
