Selected AbstractsARGUING OVER [THE] REMOTE CONTROL: WHY INDIGENOUS POLICY NEEDS TO BE BASED ON EVIDENCE AND NOT HYPERBOLEECONOMIC PAPERS: A JOURNAL OF APPLIED ECONOMICS AND POLICY, Issue 1 2007BOYD H. HUNTER Recent public debate on Indigenous issues has been provoked, inter alia, by a 2005 Centre for Independent Studies paper by Helen Hughes and Jenness Warin, who focused on the extent to which policies have been effective in improving the living conditions of Indigenous Australians since the era of self-determination commenced. Unfortunately, the quality of historical data is questionable, and hence we need an appreciation of the reliability of estimates. The 2002 National Aboriginal and Torres Strait Islander Social Survey allows a detailed interrogation of the reliability of estimates. This paper critically analyses socioeconomic changes between 1994 and 2002 for remote and other areas by comparing the recent data with analogous data collected in 1994. Changes in health status and a range of socio-economic indicators are documented to provide a more balanced assessment of the level of economic and social development in the respective areas.

[source] Dynamic control of split flow in packed column supercritical fluid chromatography using dual resistively heated restrictorsJOURNAL OF SEPARATION SCIENCE, JSS, Issue 14 2009Jian Jun Li Abstract Remote control of the vent/detector split flow ratio in packed column supercritical fluid chromatography (pSFC) with flame ionization detector (FID) is demonstrated using a dual heated restrictor method. Restrictors stemming from a Tee at the separation column outlet were, respectively, fixed into an FID and a vent port, and their individual temperatures were controlled using resistively heated wires. Subsequently, both system pressure and split flow could be manipulated. For example, for applied restrictor temperatures examined up to 600°C, corresponding vent/FID split flow ratios between 2 and 7 were observed depending on the port heated. As well, column pressures around 16,23 MPa were also achievable over the same range. Conversely, isobaric altering of the split flow ratio was possible when opposing positive and negative temperature gradients were applied at the two restrictors. Under these conditions, the system pressure varied less than 1% RSD over a 10 min period. As an application, the method was used to establish stable detector operation in the analysis of n -alkanes under pSFC-FID conditions that initiated flame instability. Results indicate that this technique could be a relatively simple and inexpensive means of controlling system pressure and detector split flow ratios in pSFC-FID. [source] Considering safety issues in minimum losses reconfiguration for MV distribution networksEUROPEAN TRANSACTIONS ON ELECTRICAL POWER, Issue 5 2009Angelo Campoccia Abstract This paper offers a new perspective over the traditional problem of the multiobjective optimal reconfiguration of electrical distribution systems in regular working state. The issue is indeed here formulated including also safety issues. Indeed, dimensioning the earth electrodes of their own secondary substations, distribution companies take into account the probable future configurations of the network due to transformations of overhead lines into cable lines or realization of new lines. On the contrary, they do not consider that, during normal working conditions, the structure of the network can be modified for long periods as a consequence of reconfiguration manoeuvres, with differences between the design current of the earthing systems and the fault current in certain substations significant. As a consequence, often distribution companies limit the implementation of the optimal reconfiguration layouts because they are unable to suitably evaluate the safety issue. In the paper, the problem is formulated including a further objective in order to account for the safety. A suitable constrained multiobjective formulation of the reconfiguration problem is therefore used aiming at: the minimal power losses operation, the verification of safety at distribution substations, the load balancing among the HV/MV transformers while keeping the voltage profile regular. The application carried out uses an NSGA-II algorithm whose performance is compared to that of a fuzzy logic-based multiobjective evolutionary algorithm. In the considered automated network, the remote control of tie-switches is possible and their layout is the optimization variable. After a brief description of the optimal reconfiguration problem for automated distribution networks, the most recent papers on the topic are reported and commented. Then the problem formulation and the solution algorithm are described in detail. Finally, test results on a large MV distribution network are reported and discussed.

[source] Investigating the performance of a middleware protocol architecture for tele-measurementINTERNATIONAL JOURNAL OF COMMUNICATION SYSTEMS, Issue 5 2008Luca Berruti Abstract The rapid growth of network infrastructures and the large availability of instrumentation supporting remote control have encouraged the deployment of complex and sophisticated laboratories and the design of software platforms for accessing the resources present there. Although the market offers several solutions to remotely manage equipment, little attention has been paid to the hardware and software architectures devoted to control distance learning experimental environments and to manage laboratories consisting of heterogeneous devices. The paper illustrates the architectural approach adopted within the LABNET project and describes in detail the main software components of the devised platform, which allows to exploit the instrumentation via a common Web user interface, thus making the system available independent of any specific (commercial) environment or application. Specifically, attention is focused on the LABNET server (LNS), which represents the supervising central unit and, therefore, a very critical element of the system. The paper mainly points out the architecture and protocols at the basis of the LNS and discusses a set of performance tests aimed at proving the effectiveness of the system and comparing it with a well-known commercial solution.

[source] Home Monitoring in Patients with Implantable Cardiac Devices: Is There a Potential Reduction of Stroke Risk?JOURNAL OF CARDIOVASCULAR ELECTROPHYSIOLOGY, Issue 11 2009Results from a Computer Model Tested Through Monte Carlo Simulations Introduction: Patients with pacemakers and implantable defibrillators (ICD) may experience asymptomatic atrial fibrillation (AF), detected with a delay depending on the in-person follow-up schedule. Home monitoring (HM) remote control with automatic alerts for AF may drive early anticoagulation, potentially reducing stroke risk. Methods and Results: A sample of 136 pacemaker (103) and ICD (33) patients with or without cardiac resynchronization therapy not taking anticoagulation at implant were monitored remotely with HM. Upon HM alerts for AF, patients were recalled to update therapy. Two-year data were entered in a computer Monte Carlo model, simulating 4,000 virtual subjects with the same AF and CHADS2 stroke risk distribution of our real population. Simulations reproduced a 2-year follow-up. Two thousand subjects were supposed to be followed with HM (HM group) and 2,000 with standard in-person follow-up (SF group) at 3, 6, 9, or 12 months. Two-year Kaplan-Meier cumulative probability of ,24-hour AF was 15.6% (95%CI 8.5,23.3%); the AF-related symptom rate was 27% and the median CHADS2 score was 2. As a result of simulations, stroke incidence in case of AF was 2.3 ± 1.1% in the HM group and 2.4 ± 1.1%, 2.5 ± 1.2%, 2.7 ± 1.2%, and 2.9 ± 1.3% in the SF group with 3-, 6-, 9-, and 12-month follow-up programs, with odds ratios of 0.97 (95%CI 0.93,1.01), 0.91 (0.88,0.95), 0.87 (0.84,0.90), and 0.82 (0.79,0.85) (HM better if odds ratios <1), respectively. Conclusions: Daily HM potentially reduces the stroke risk by 9% to 18% with respect to SF with intervisit intervals of 6 to 12 months. [source] MxCuBE: a synchrotron beamline control environment customized for macromolecular crystallography experimentsJOURNAL OF SYNCHROTRON RADIATION, Issue 5 2010José Gabadinho The design and features of a beamline control software system for macromolecular crystallography (MX) experiments developed at the European Synchrotron Radiation Facility (ESRF) are described. This system, MxCuBE, allows users to easily and simply interact with beamline hardware components and provides automated routines for common tasks in the operation of a synchrotron beamline dedicated to experiments in MX. Additional functionality is provided through intuitive interfaces that enable the assessment of the diffraction characteristics of samples, experiment planning, automatic data collection and the on-line collection and analysis of X-ray emission spectra. The software can be run in a tandem client-server mode that allows for remote control and relevant experimental parameters and results are automatically logged in a relational database, ISPyB. MxCuBE is modular, flexible and extensible and is currently deployed on eight macromolecular crystallography beamlines at the ESRF. Additionally, the software is installed at MAX-lab beamline I911-3 and at BESSY beamline BL14.1. [source] Teleworkflow: supporting remote control with Workflow Management SystemsNEW TECHNOLOGY, WORK AND EMPLOYMENT, Issue 2 2007Diana Limburg This paper explores the links between the management of remote workers and dispersed teams and the use of Workflow Management Systems. Using case studies, it demonstrates how such systems can support diverse control approaches independent of the location of employees and managers and thus enhance the success of distant working. [source] Questioning as an instructional method: Does it affect learning from lectures?APPLIED COGNITIVE PSYCHOLOGY, Issue 6 2009Julie Campbell What can be done to improve student engagement and learning in college lectures? One approach is to ask questions that students answer during the lecture. In two lab experiments, students received a 25-slide PowerPoint lecture in educational psychology that included four inserted multiple-choice questions (questioning group) or four corresponding statements (control group). Students in the questioning group used a personal response system (PRS), in which they responded to questions using a hand-held remote control, saw a graph displaying the percentage of students voting for each answer, and heard the teacher provide an explanation for the correct answer. Students in the control group received the corresponding slide as a statement and heard the teacher provide an explanation. The questioning group outperformed the control group on a retention test in Experiment 1 (d,=,1.23) and on a transfer test in Experiment 2 (d,=,0.74), but not on other tests. The results are consistent with a generative theory of learning, and encourage the appropriate use of questioning as an instructional method. Copyright © 2008 John Wiley & Sons, Ltd. [source] Blending telephony and IPTV: Building the TV-link service package using the Alcatel-Lucent Service BrokerÔBELL LABS TECHNICAL JOURNAL, Issue 1 2007Andre Beck This paper discusses the design and implementation of blended services, composite services whose base component services interact within a common control structure. The paper focuses on blended services that combine aspects of Internet Protocol television (IPTV) and IP Multimedia Subsystem, (IMS)-based telephony services and, in particular, focuses on a service that blends TV viewing and telephone call-handling functions. If a subscriber to this service receives a telephone call while watching TV, the caller ID is displayed on the subscriber's TV screen and the subscriber can signal call control instructions using the set-top box remote control. In this service blend, functions from each base service are coordinated with actions in the other. The mechanism allowing this service is an information channel that allows status and control information to move between the subscriber's set-top box and the IMS system. The services described in this paper are built upon a software foundation called the Alcatel-Lucent Service BrokerÔ platform, a platform that has unique capabilities to support such an information channel and to serve as the gateway between IMS and digital TV. This foundation offers service developers a set of important functions for the creation of blended services. Specifically, the Alcatel-Lucent Service Broker offers a means of controlling the invocation of base services, a means of communicating through different protocols, and support for large-scale deployment and for service customization. © 2007 Alcatel-Lucent. [source] Good governance is not about control,it's about remote controlBOARD LEADERSHIP: POLICY GOVERNANCE IN ACTION, Issue 49 2000Article first published online: 15 MAR 200 Marcus Buckingham and Curt Coffman of the Gallup Organization have written a challenging book for managers, First, Break All the Rules (Simon & Schuster, 1999). Their conclusions are built on twenty-five years' research with over a million employees. Whereas the authors deal with many facets that they found to characterize great managers, in this article I want to relate one of their points to principles of Policy Governance.
