  1. PERFORMANCE EVALUATION OF AN ALTERNATIVE CONTROLLER FOR BLUETOOTH SERVICE DISCOVERY

    Directory of Open Access Journals (Sweden)

    M. Sughasiny

    2012-06-01

    Full Text Available Bluetooth is a short range radio technology to form a small wireless system. It is used in low –cost, low power ad-hoc networks and it suffers from long service discovery delay and high power consumption. Bluetooth employs the 2.4 GHz ISM band, sharing the same bandwidth with the wireless LAN implementing the IEEE 802.11 standards. Thus it causes significantly lower interference. For improving the efficiency of SDP, we present an implementation of Bluetooth 2.1 in the NS-2 simulator, discuss the IEEE 802.11b as a Bluetooth controller and propose a new alternative Bluetooth Controller based on Adaptive Frequency Hopping techniques using Amplifier Power. The resulting approach significantly reduces the service discovery time, thereby lowering power consumption and increasing the throughput. We present the benefits of our new approach and compare it with existing approach using NS-2 Simulations and we have presented the comparison graphs in support of our approach.

    1992-03-01

    Contract medical transcription services can be of great assistance in meeting the demands for transcription, without jeopardizing patient, physician, or institutional confidentiality. You simply must require the contract service to provide at least the same degree of protection and preservation of confidentiality that you should require inhouse. To achieve this you must make these requirements explicit, comprehensive, comprehensible, believable, and enforceable. Discuss the requirements with prospective contractors. Review them at least annually with existing contractors and when contracts are due for renewal. Be sure to specify the consequence of breaching confidentiality, and if there are breaches, enforce the terms of the contract. Consult your institution's legal counsel both in developing the contract and in enforcing its provisions. Take into consideration your department's and institution's policies, AHIMA's statement on confidentiality, as well as local, state, and federal laws. Above all, never lose sight of the patient. Ultimately, it is not patient information that you are obligated to protect. It is the patient.

    Meanwhile, the producer-independent service is more than an alternative. In order to offer a successful service to the offers, many requirements must be fulfilled. A substantial characteristic is the competence, i.e. the capability of all coworkers in the company to justice to the individual requirements. For this, Deutsche Windtechnik Service GmbH and Co. KG (Ostenfeld, Federal Republic of Germany) has specialized in special types of plants. Further requirements are the organisational structure, the service strategy, the existing service network, the data remote monitoring, warranties and guarantee, documentation and communication.

    2001-01-01

    The Globus information service wasn't working well. There were many updates of data from Globus daemons which saturated the single server and users couldn't retrieve information. We created a second server for NASA and Alliance. Things were great on that server, but a bit slow on the other server. We needed to know exactly how the information service was being used. What were the best servers and configurations? This viewgraph presentation gives an overview of the evaluation of alternative designs for a Grid Information Service. Details are given on the workload characterization, methodology used, and the performance evaluation.

    The evolving nature of the NASA space enterprise compels the agency to develop new and innovative space systems concepts. NASA, working with increasingly strained budgets and a declining manpower base, is attempting to transform from operational activities to procurement of commercial services. NASA's current generation reusable launch vehicle, the Shuttle, is in transition from a government owned and operated entity to a commercial venture to reduce the civil servant necessities for that program. NASA foresees its second generation launch vehicles being designed and operated by industry for commercial and government services. The "service" concept is a pioneering effort by NASA. The purpose the "service" is not only to reduce the civil servant overhead but will free up government resources for further research - and enable industry to develop a space business case so that industry can sustain itself beyond government programs. In addition, NASA desires a decreased responsibility thereby decreasing liability. The Second Generation Reusable Launch Vehicle (RLV) program is implementing NASA's Space Launch Initiative (SLI) to enable industry to develop the launch vehicles of the future. The Alternate Access to Station (AAS) project office within this program is chartered with enabling industry to demonstrate an alternate access capability for the International Space Station (ISS). The project will not accomplish this by traditional government procurement methods, not by integrating the space system within the project office, or by providing the only source of business for the new capability. The project funds will ultimately be used to purchase a service to take re-supply cargo to the ISS, much the same as any business might purchase a service from FedEx to deliver a package to its customer. In the near term, the project will fund risk mitigation efforts for enabling technologies. AAS is in some ways a precursor to the 2nd Generation RLV. By accomplishing ISS resupply

    In order to realize alternative fueling for military and commercial use, the industry has set forth guidelines that must be met by each fuel. These aviation fueling requirements are outlined in MIL-DTL-83133F(2008) or ASTM D 7566 Annex (2011) standards, and are classified as "drop-in" fuel replacements. This report provides combustor performance data for synthetic-paraffinic-kerosene- (SPK-) type (Fischer-Tropsch (FT)) fuel and blends with JP-8+100, relative to JP-8+100 as baseline fueling. Data were taken at various nominal inlet conditions: 75 psia (0.52 MPa) at 500 degF (533 K), 125 psia (0.86 MPa) at 625 degF (603 K), 175 psia (1.21 MPa) at 725 degF (658 K), and 225 psia (1.55 MPa) at 790 degF (694 K). Combustor performance analysis assessments were made for the change in flame temperatures, combustor efficiency, wall temperatures, and exhaust plane temperatures at 3, 4, and 5 percent combustor pressure drop (DP) for fuel:air ratios (F/A) ranging from 0.010 to 0.025. Significant general trends show lower liner temperatures and higher flame and combustor outlet temperatures with increases in FT fueling relative to JP-8+100 fueling. The latter affects both turbine efficiency and blade and vane lives.

  16. Alternative High-Performance Ceramic Waste Forms

    Energy Technology Data Exchange (ETDEWEB)

    Sundaram, S. K. [Alfred Univ., NY (United States)

    2017-02-01

    This final report (M5NU-12-NY-AU # 0202-0410) summarizes the results of the project titled “Alternative High-Performance Ceramic Waste Forms,” funded in FY12 by the Nuclear Energy University Program (NEUP Project # 12-3809) being led by Alfred University in collaboration with Savannah River National Laboratory (SRNL). The overall focus of the project is to advance fundamental understanding of crystalline ceramic waste forms and to demonstrate their viability as alternative waste forms to borosilicate glasses. We processed single- and multiphase hollandite waste forms based on simulated waste streams compositions provided by SRNL based on the advanced fuel cycle initiative (AFCI) aqueous separation process developed in the Fuel Cycle Research and Development (FCR&D). For multiphase simulated waste forms, oxide and carbonate precursors were mixed together via ball milling with deionized water using zirconia media in a polyethylene jar for 2 h. The slurry was dried overnight and then separated from the media. The blended powders were then subjected to melting or spark plasma sintering (SPS) processes. Microstructural evolution and phase assemblages of these samples were studied using x-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersion analysis of x-rays (EDAX), wavelength dispersive spectrometry (WDS), transmission electron spectroscopy (TEM), selective area x-ray diffraction (SAXD), and electron backscatter diffraction (EBSD). These results showed that the processing methods have significant effect on the microstructure and thus the performance of these waste forms. The Ce substitution into zirconolite and pyrochlore materials was investigated using a combination of experimental (in situ XRD and x-ray absorption near edge structure (XANES)) and modeling techniques to study these single phases independently. In zirconolite materials, a transition from the 2M to the 4M polymorph was observed with increasing Ce content. The resulting

    Danehy, L J; Scutt, R C; Stonehill, E

    1985-05-01

    Because the performance of shared service and tax-exempt status under Section 501(c)(3) of the Internal Revenue Code can be incompatible, hospitals planning to provide services to each other or to other organizations on a fee-for-service basis may wish to do so through a separate corporate entity. Using either a Section 501(e) shared service organization, a Sub-chapter T cooperative, or a taxable business corporation, a compromise can be reached between operational flexibility and tax benefits.

  1. Integrating complementary and alternative medicine into mainstream healthcare services: the perspectives of health service managers.

    Science.gov (United States)

    Singer, Judy; Adams, Jon

    2014-05-22

    Complementary and alternative medicine (CAM) is increasingly included within mainstream integrative healthcare (IHC) services. Health service managers are key stakeholders central to ensuring effective integrative health care services. Yet, little research has specifically investigated the role or perspective of health service managers with regards to integrative health care services under their management. In response, this paper reports findings from an exploratory study focusing exclusively on the perspectives of health service managers of integrative health care services in Australia regarding the role of CAM within their service and the health service managers rational for incorporating CAM into clinical care. Health service managers from seven services were recruited using purposive and snowball sampling. Semi-structured interviews were conducted with the health service managers. The services addressed trauma and chronic conditions and comprised: five community-based programs including drug and alcohol rehabilitation, refugee mental health and women's health; and two hospital-based specialist services. The CAM practices included in the services investigated included acupuncture, naturopathy, Western herbal medicine and massage. Findings reveal that the health service managers in this study understand CAM to enhance the holistic capacity of their service by: filling therapeutic gaps in existing healthcare practices; by treating the whole person; and by increasing healthcare choices. Health service managers also identified CAM as addressing therapeutic gaps through the provision of a mind-body approach in psychological trauma and in chronic disease management treatment. Health service managers describe the addition of CAM in their service as enabling patients who would otherwise not be able to afford CAM to gain access to these treatments thereby increasing healthcare choices. Some health service managers expressly align the notion of treating the whole person

    2017-11-01

    Surveys of military personnel indicate substantial use of complementary and alternative medicine (CAM) that possibly exceeds use in the general U.S. Although military treatment facilities (MTFs) are known to offer CAM, surveys do not indicate where service members receive this care. This study offers a comprehensive system-wide accounting of the types of CAM offered across the military health system (MHS), the conditions for which it is used, and its level of use. These data will help MHS policymakers better support their population's healthcare needs. A census survey of MTFs across the MHS on all CAM use, supplemented where possible by MHS utilization data. Types of CAM offered by each MTF, reasons given for offering CAM, health conditions for which CAM is used, and number of patient visits for each CAM type. Of the 142 MTFs in the MHS, 133 (94%) responded. Of these, 110 (83%) offer at least one type of CAM and 5 more plan to offer CAM services in the future. Larger MTFs (those reporting ≥25,000 beneficiaries enrolled) are both more likely to offer CAM services (p 10) of different types of CAM (p = 0.010) than smaller MTFs. Three-fourths of MTFs offering CAM provide stress management/relaxation therapy, two-thirds provide acupuncture, and at least half provide progressive muscle relaxation, guided imagery, chiropractic, and mindfulness meditation. MTFs most commonly report CAM use for pain and mental health conditions. Acupuncture and chiropractic are most commonly used for pain, and stress management/relaxation therapy and mind-body medicine combinations are most often used for mental health-related conditions. We estimate 76,000 CAM patient encounters per month across the MHS. The availability of CAM services in the MHS is widespread and is being used to address a range of challenging pain and mental health conditions.

  7. Open Search Environments: The Free Alternative to Commercial Search Services

    Directory of Open Access Journals (Sweden)

    Adrian O'Riordan

    2014-06-01

    Full Text Available Open search systems present a free and less restricted alternative to commercial search services. This paper explores the space of open search technology looking in particular at the issue of interoperability. A description of current protocols and formats for engineering open search applications is presented. The suitability of these technologies and issues around their adoption and operation are discussed. This open search approach is especially proving a fitting choice in applications involving the harvesting of resources and information integration. Principal among the technological solutions are OpenSearch and SRU. OpenSearch and SRU implement a federated model to enable existing and new search engines and search clients communicate. Applications and instances where Opensearch and SRU can be combined are presented. Other relevant technologies such as OpenURL, Apache Solr, and OAI-PMH are also discussed. The deployment of these freely licensed open standards in digital library applications is now a genuine alternative to commercial or proprietary systems.

    2003-12-01

    Hydrogen has promise to be the fuel of the future. Its use as a chemical reagent and as a rocket propellant has grown to over eight million metric tons per year in the United States. Although use of hydrogen is abundant, it has not been used extensively as a transportation fuel. To assess the viability of hydrogen as a transportation fuel and the viability of producing hydrogen using off-peak electric energy, Pinnacle West Capital Corporation (PNW) and its electric utility subsidiary, Arizona Public Service (APS) designed, constructed, and operates a hydrogen and compressed natural gas fueling station—the APS Alternative Fuel Pilot Plant. This report summarizes the design of the APS Alternative Fuel Pilot Plant and presents lessons learned from its design and construction. Electric Transportation Applications prepared this report under contract to the U.S. Department of Energy’s Advanced Vehicle Testing Activity. The Idaho National Engineering and Environmental Laboratory manages these activities for the Advanced Vehicle Testing Activity.

    Haynes, R.A.; Pierson, L.G.

    1997-01-01

    Networks at major computational organizations are becoming increasingly complex. The introduction of large massively parallel computers and supercomputers with gigabyte memories are requiring greater and greater bandwidth for network data transfers to widely dispersed clients. For networks to provide adequate data transfer services to high performance computers and remote users connected to them, the networking components must be optimized from a combination of internal and external performance criteria. This paper describes research done at Sandia National Laboratories to model network data services and to visualize the flow of data from source to sink when using the data services.

  16. Reconsidering the measurement of ancillary service performance.

    Science.gov (United States)

    Griffin, D T; Rauscher, J A

    1987-08-01

    Prospective payment reimbursement systems have forced hospitals to review their costs more carefully. The result of the increased emphasis on costs is that many hospitals use costs, rather than margin, to judge the performance of ancillary services. However, arbitrary selection of performance measures for ancillary services can result in managerial decisions contrary to hospital objectives. Managerial accounting systems provide models which assist in the development of performance measures for ancillary services. Selection of appropriate performance measures provides managers with the incentive to pursue goals congruent with those of the hospital overall. This article reviews the design and implementation of managerial accounting systems, and considers the impact of prospective payment systems and proposed changes in capital reimbursement on this process.

  17. Evaluating a NoSQL Alternative for Chilean Virtual Observatory Services

    2015-09-01

    Currently, the standards and protocols for data access in the Virtual Observatory architecture (DAL) are generally implemented with relational databases based on SQL. In particular, the Astronomical Data Query Language (ADQL), language used by IVOA to represent queries to VO services, was created to satisfy the different data access protocols, such as Simple Cone Search. ADQL is based in SQL92, and has extra functionality implemented using PgSphere. An emergent alternative to SQL are the so called NoSQL databases, which can be classified in several categories such as Column, Document, Key-Value, Graph, Object, etc.; each one recommended for different scenarios. Within their notable characteristics we can find: schema-free, easy replication support, simple API, Big Data, etc. The Chilean Virtual Observatory (ChiVO) is developing a functional prototype based on the IVOA architecture, with the following relevant factors: Performance, Scalability, Flexibility, Complexity, and Functionality. Currently, it's very difficult to compare these factors, due to a lack of alternatives. The objective of this paper is to compare NoSQL alternatives with SQL through the implementation of a Web API REST that satisfies ChiVO's needs: a SESAME-style name resolver for the data from ALMA. Therefore, we propose a test scenario by configuring a NoSQL database with data from different sources and evaluating the feasibility of creating a Simple Cone Search service and its performance. This comparison will allow to pave the way for the application of Big Data databases in the Virtual Observatory.

    The aims of this paper are (1) to identify the characteristics of maintenance service providers that directly impact maintenance service quality, using 18 independent covariables; (2) to quantify the change in risk these covariables present to service quality, measured in terms of equipment turnaround time (TAT). A survey was applied to every maintenance service provider (n = 19) for characterization purposes. The equipment inventory was characterized, and the TAT variable recorded and monitored for every work order of each service provider (N = 1,025). Finally, the research team conducted a statistical analysis to accomplish the research objectives. The results of this study offer strong empirical evidence that the most influential variables affecting the quality of maintenance service performance are the following: type of maintenance, availability of spare parts in the country, user training, technological complexity of the equipment, distance between the company and the hospital, and the number of maintenance visits performed by the company. The strength of the results obtained by the Cox model built are supported by the measure of the Rp,e(2) = 0.57 with a value of Rp,e= 0.75. Thus, the model explained 57% of the variation in equipment TAT, with moderate high positive correlation between the dependent variable (TAT) and independent variables.

  19. Discriminating performance of disposal alternatives - can it be done

    International Nuclear Information System (INIS)

    A basic principle of radioactive waste disposal is that the degree of isolation of the waste from human exposure should increase with the increase in the hazard of the waste. Most disposal concepts, including low-level waste disposal concepts, rely on isolation, limits on release rates, environmental retention, or environmental dilution to provide the necessary margin of safety. The answer to the question posed by the title of this paper is a qualified yes, depending on the measure of performance. Three methodologies for discriminating performance of low-level waste disposal alternatives are described. The disposal technology classification system distinguishes technologies on the basis of three qualitative performance functional features. These are relationship to natural grade, extent of cover, and presence and type of structure. Multi-attribute utility estimation is a semiquantitative decision analysis methodology used to rank disposal alternatives by taking into account both the technical merit of a particular alternative and the relative importance of issues and factors used to make the technical judgment. Use of this decision methodology by several states and compacts to rank proposed near surface disposal alternatives is described. Multipathway performance assessment is a quantitative methodology that uses models to evaluate the abilities of different disposal technologies to limit the release of radioactivity to man and the environment. Unfortunately, the degree of sophistication of present models is such that discrimination between technologies is, generally, determined by differences in input parameters that are usually difficult to justify. Several examples of the use of pathway modeling are presented. 11 references, 2 figures, 5 tables

    2018-06-01

    Prolonged sitting is a risk factor for several diseases and the prevalence of worksite-based interventions such as sit-to-stand workstations is increasing. Although their impact on sedentary behaviour has been regularly investigated, the effect of working in alternating body postures on cognitive performance is unclear. To address this uncertainty, 45 students participated in a two-arm, randomised controlled cross-over trial under laboratory conditions. Subjects executed validated cognitive tests (working speed, reaction time, concentration performance) either in sitting or alternating working postures on two separate days (ClinicalTrials.gov Identifier: NCT02863731). MANOVA results showed no significant difference in cognitive performance between trials executed in alternating, standing or sitting postures. Perceived workload did not differ between sitting and alternating days. Repeated measures ANOVA revealed significant learning effects regarding concentration performance and working speed for both days. These results suggest that working posture did not affect cognitive performance in the short term. Practitioner Summary: Prior reports indicated health-related benefits based on alternated (sit/stand) body postures. Nevertheless, their effect on cognitive performance is unknown. This randomised controlled trial showed that working in alternating body postures did not influence reaction time, concentration performance, working speed or workload perception in the short term.

    Maintaining an outpatient practice and providing high-quality inpatient care pose significant challenges to the traditional call team approach. To introduce a unique rotating hospitalist inpatient program and assess its clinical, educational, and financial impact. The chief of service (COS) program requires 1 attending physician to rotate weekly as chief of the inpatient service with no conflicting elective duties. This was a retrospective internal billing data review performed at a tertiary pediatric hospital. A total of 1241 patients were evaluated by the COS from October 2012 through October 2013. All patients were treated by the inpatient service under the supervision of the COS. A retrospective analysis of patient encounters and procedures, including International Classification of Diseases, Ninth Revision (ICD-9) and Current Procedural Terminology (CPT) codes, locations of service, clinicians, service dates, and average weekly relative value units (RVUs). Over the study period, the COS was involved in the care of 1241 patients, generating 2786 billable patient encounters. The COS averaged 11.2 patient encounters per day. The most common reasons for consultation were respiratory distress, dysphagia, and stridor. Of patient encounters, 63.0% resulted in a procedure; 82.8% of those procedures were performed in the operating room with the most common being lower airway endoscopy (340 [19.4%]). The average weekly RVUs for the COS (232) were comparable with those of the average weekly outpatient clinic and procedural RVUs of the other otolaryngology faculty in the group (240). The COS program was created to meet the clinical, educational, and organizational demands of a high-volume and high-acuity inpatient service. It is a financially sustainable model with unique advantages, particularly for the staff who maintain their outpatient practices without disruption and for the trainees who have the opportunity to work closely with the entire faculty.

    2007-01-01

    Full Text Available In recent years, mobile devices have become relatively more powerful with additional features which have the capability to provide multimedia streaming. Better, faster and more reliable data storage solutions in the mobile messaging platform have become more essential with these additional improvements. The existing mobile messaging infrastructure, in particular the data storage platform has become less proficient in coping with the increased demand for its services. This demand especially in the mobile messaging area (i.e. SMS – Short Messaging Service, MMS – Multimedia Messaging Service, which may well exceeded 250,000 requests per second, means that the need to evaluate competing data management systems has become not only necessary but essential. This paper presents an evaluation of SMS and MMS platforms using different database management systems – DBMS and recommends the best data management strategies for these platforms.

    2015-01-01

    Ablative thermal protection systems are commonly used as protection from the intense heat during re-entry of a space vehicle and have been used successfully on many missions including Stardust and Mars Science Laboratory both of which used PICA - a phenolic based ablator. Historically, phenolic resin has served as the ablative polymer for many TPS systems. However, it has limitations in both processing and properties such as char yield, glass transition temperature and char stability. Therefore alternative high performance polymers are being considered including cyanate ester resin, polyimide, and polybenzoxazine. Thermal and mechanical properties of these resin systems were characterized and compared with phenolic resin.

  15. Engaging service providers in improving industry performance

    International Nuclear Information System (INIS)

    Oberth, R.

    2012-01-01

    Effective task leadership is the key to achieving results in the nuclear industry and in most other industries. One of the themes of this conference is to discuss how the nuclear industry can undertake Issue-Identification and Definition as a means of 'identifying what needs attention' and then 'defining what needs to be done to make that happen'. I will explore this theme from the perspective of the 'Service Provider' - which by the definition of this conference includes everyone not within an operating utility - meaning 'those involved in everything from inspection and repair to research and plant architecture' - basically the member companies of my association, OCI. Our members take the definition of the roles and responsibilities of the 'Service Provider' community very seriously. In the context of this discussion a key utility function is the early definition of requirements and expectations of Service Providers in supplying to these requirements. Let's explore for a moment the Service Provider role and perspective. Service Providers are by nature pro-active - they seek ways to engage with utilities (and tier one vendors) to solve problems and achieve good outcomes. They come to industry conferences like this one to learn about upcoming utility programs and supply opportunities and how they can improve performance. Service Providers particularly want to hear senior utility people comment on emerging issues even those at the very early identification stage. Some Clarification of Roles is in Order - as that is the focus of this conference: 'Issue-Identification and Definition'. 'Issue-Identification' is the utility's job - it is the utility's role to identify as early as possible 'what needs attention and what their needs and expectations are'. This takes place before service provider engagement. 'Issue-Definition' is more challenging. It means 'determining and prioritizing what needs to be done to deal with the situation at hand'. This typically involves

    The transformation and integration of government services, enabled by the use of new technologies such as application servers and Web services, is fundamental to reduce the cost of government and improving service outcomes to citizens. Many core Government information systems comprise applications running on legacy mainframes, databases and transaction processing monitors. As Governments worldwide provide direct access over the Internet to these legacy applications from the general public, they may be exposed to workloads well above the origin design parameters of these back-end systems. This creates a significant risk of high profile failures for Government agencies whose newly integrated systems become overloaded. In this paper we describe how we conducted a performance assessment of a business-critical, Internet-facing Web services that integrated new and legacy systems from two Australian Government agencies. We leveraged prototype tools from our own research along with known techniques in performance modeling. We were able to clearly demonstrate that the existing hardware and software would be adequate to handle the predicted workload for the next financial year. We were also able to do ‘what-if’ analysis and predict how the system can perform with alternative strategies to scale the system. We conclude by summarizing the lessons learnt, including the importance of architecture visibility, benchmarking data quality, and measurement feasibility due to issues of outsourcing, privacy legislation and cross-agency involvement.

    As the Army moves toward more mobile and agile forces and continued sustainment of numerous high-cost legacy logistics management systems, the requirement for wireless connectivity and a wireless network to supporting organizations has become ever more critical. There are currently several Army communications initiatives underway to resolve this wireless connectivity issue. However, to fully appreciate and understand the value of these initiatives, a Tradeoff Analysis is needed. The present study seeks to identify and assess solutions. The analysis identified issues that impede Interim Brigade Combat Team (IBCT) communication system integration and outlined core requirements for sharing of logistics data between the field and Army battle command systems. Then, the analysis examined wireless communication alternatives as possible solutions for IBCT logistics communications problems. The current baseline system was compared with possible alternatives involving tactical radio systems, wireless/near term digital radio, cellular satellite, and third-generation (3G) wireless technologies. Cellular satellite and 3G wireless technologies offer clear advantages and should be considered for later IBCTs.

    This memo summarizes the current status of the Ceph block storage service as it is used for OpenStack Cinder Volumes and Glance Images as of May 2014. We present the block storage activity on the current cluster, measuring IOPS and latencies, and present a cost/benefit analysis of using SSDs to optimize the cost and performance efficiency of the service. During tests in collaboration with IT-CF, we have concluded that by adding SSDs as the synchronous write journals (used to guarantee data durability), we are able increase the IOPS capacity by 4-5 times, at a cost of decreasing the available volume by 20%. Further, the testing has shown that the Ceph implementation is able to operate at the limit of the hardware performance; software-induced performance limitations were not yet observed in either the spinning disk or SSD configurations. In addition, we believe that increasing small write performance with SSDs is applicable only to the block storage use-case; high-bandwidth use-cases such as physics data stora...

  1. Performance of alternative refrigerants for residential air-conditioning applications

    International Nuclear Information System (INIS)

    Park, Ki-Jung; Seo, Taebeom; Jung, Dongsoo

    2007-01-01

    In this study, performances of two pure hydrocarbons and seven mixtures composed of propylene, propane, HFC152a, and dimethylether were measured to substitute for HCFC22 in residential air-conditioners and heat pumps. Thermodynamic cycle analysis was carried out to determine the optimum compositions before testing and actual tests were performed in a breadboard-type laboratory heat pump/air-conditioner at the evaporation and condensation temperatures of 7 and 45 deg. C, respectively. Test results show that the coefficient of performance of these mixtures is up to 5.7% higher than that of HCFC22. While propane showed a 11.5% reduction in capacity, most of the fluids had a similar capacity to that of HCFC22. For these fluids, compressor-discharge temperatures were reduced by 11-17 deg. C. For all fluids tested, the amount of charge was reduced by up to 55% as compared to HCFC22. Overall, these fluids provide good performances with reasonable energy-savings without any environmental problem and thus can be used as long-term alternatives for residential air-conditioning and heat-pumping applications

    The traditional incremental approach to computerization presents substantial problems as systems develop and grow. The Data Base Management System approach to computerization was developed to overcome the problems resulting from implementing computer applications one at a time. The authors describe the applications approach and the alternative Data Base Management System (DBMS) approach through their developmental history, discuss the technology of DBMS components, and consider the implications of choosing the DBMS alternative. Human service managers need an understanding of the DBMS alternative and its applicability to their agency data processing needs. The basis for a conscious selection of computing alternatives is outlined.

    Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F(2008) or ASTM D 7566 (2010) standards, respectively, and are classified as drop-in fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are certified individually on the basis of feedstock. Adherence to alternate fuels and fuel blends requires smart fueling systems or advanced fuel-flexible systems, including combustors and engines without significant sacrifice in performance or emissions requirements. This paper provides preliminary performance (Part A) and emissions and particulates (Part B) combustor sector data for synthetic-parafinic-kerosene- (SPK-) type fuel and blends with JP-8+100 relative to JP-8+100 as baseline fueling.

  11. Monitoring the performance of an alternative cover using caisson lysimeters

    Energy Technology Data Exchange (ETDEWEB)

    Waugh, W.J.; Smith, G.M.; Mushovic, P.S.

    2004-02-29

    The U.S. Department of Energy (DOE) office in Grand Junction, Colorado, and the U.S. Environmental Protection Agency (EPA), Region 8, collaborated on a series of field lysimeter studies to design and monitor the performance of an alternative cover for a uranium mill tailings disposal cell at the Monticello, Utah, Superfund Site. Because groundwater recharge is naturally limited at Monticello in areas with thick loess soils, DOE and EPA chose to design a cover for Monticello using local soils and a native plant community to mimic this natural soilwater balance. Two large drainage lysimeters fabricated of corrugated steel culvert lined with high-density polyethylene were installed to evaluate the hydrological and ecological performance of an alternative cover design constructed in 2000 on the disposal cell. Unlike conventional, lowpermeability designs, this cover relies on (1) the water storage capacity of a 163-cm soil “sponge” layer overlying a sand-and-gravel capillary barrier to retain precipitation while plants are dormant and (2) native vegetation to remove precipitation during the growing season. The sponge layer consists of a clay loam subsoil compacted to 1.65 g/cm2 in one lysimeter and a loam topsoil compacted to 1.45 g/cm2 in the other lysimeter, representing the range of as-built conditions constructed in the nearby disposal cell cover. About 0.1 mm of drainage occurred in both lysimeters during an average precipitation year and before they were planted, an amount well below the EPA target of <3.0 mm/yr. However, the cover with less compacted loam topsoil sponge had a 40% greater water storage capacity than the cover with overly compacted clay loam subsoil sponge. The difference is attributable in part to higher green leaf area and water extraction by plants in the loam topsoil. The lesson learned is that seemingly subtle differences in soil types, sources, and compaction can result in salient differences in performance. Diverse, seeded communities of

However, the use of fault recovery could have impact on the performance of cloud service. In this paper, we conduct a preliminary study on this issue. Cloud service performance is quantified by service response time, whose probability density function as well as the mean is derived.

  14. Towards Alliance Performance Management in Service Logistics

    Directory of Open Access Journals (Sweden)

    Bianca Keers

    2015-04-01

    Full Text Available This study explores the management of stakeholder values for alliance success. A multiple-case study method is used to analyze – within six organizations attempting to form alliances – how the management of inter-organizational dimensions of stakeholder value adds to the success of an alliance business strategy. Our study focuses on the establishment of vertical service alliances within the Dutch maritime sector, including private-private as well as public-private initiatives. The findings point toward the usefulness of developing an inter-organizational success map. Because of its comprehensive multi-stakeholder orientation, a success map can be used by alliance managers to understand management’s considerations, including the trade-offs among an alliance’s various performance drivers. This new conceptual thinking can enhance research and best practices on inter-organizational design.

    2016-12-01

    Full Text Available The aim of this study was to evaluate 2 alternative breeding systems that differ from the current system in terms of reproduction rhythm, age of females at first insemination and the age of kits at weaning and at slaughter. We measured the performance of 332 females and their offspring over 4 consecutive cycles, as well as the sustainability of the systems. We compared an intensive (group I: reproduction rhythm [RR]=35 d; first insemination [AI1]=20.6 wk of age; weaning age [WA]=32 d; slaughter age [WS]=63 d an extensive (group E: RR=49 d; AI1=16.6 wk; WA=30 d; WS=70 d and a semi-intensive system (group S: RR=42 d; AI1=19.6 wk; WA=35 d; WS=70 d considered as the control system. Sustainability was evaluated using a multicriteria assessment method that takes 14 economic, environmental and social criteria into account, for which 3 to 5 indicators were expressed as the relative score [–1; –0.5; 0; +0.5; +1] for alternative systems compared to the control system. The productivity measured at 28 d (3.5, 4.2 and 4.6 kg/AI, for groups I, S and E, respectively, at 63 d post-partum (30, 38 and 42 kg/female for 4 cycles, respectively, and the total body energy measured 3 d after the 1st and at the 4th insemination (45.4, 46.8 and 49.5 MJ, respectively, were significantly increased when the reproductive rhythm decreased (P<0.001. Before and after weaning, kit mortality decreased when the reproduction rhythm decreased (11.4, 7.3, and 1.9% and 18.3, 15.3 and 10.6% for groups I, S and E, respectively, P<0.05. Carcass quality (weight and dressing percentage was lower in I than in the S and E groups (P<0.001. On this basis, the yearly productivity per doe at weaning could be estimated at 79, 83, and 78 kg for groups I, S and E, respectively. Consequently, the productivity per reproductive cycle increases with the extensification of the breeding system. Nevertheless, compared with the current French system (S, simultaneous changes in several breeding

    2007-01-01

    Full Text Available An approach to dynamic workflow management and optimisation using near-realtime performance data is presented. Strategies are discussed for choosing an optimal service (based on user-specified criteria from several semantically equivalent Web services. Such an approach may involve finding "similar" services, by first pruning the set of discovered services based on service metadata, and subsequently selecting an optimal service based on performance data. The current implementation of the prototype workflow framework is described, and demonstrated with a simple workflow. Performance results are presented that show the performance benefits of dynamic service selection. A statistical analysis based on the first order statistic is used to investigate the likely improvement in service response time arising from dynamic service selection.

    1987-01-01

    In Mexico, youth face difficulties in obtaining reliable information on sex education and family planning through existing community programs. Two alternative strategies to provide these services are being tested in poor urban areas of Monterrey. In one experimental area, Integrated Youth Centers were established, which provide sex education and family planning services as well as counseling, academic tutoring, and recreational activities. In another area, trained young adults and community counselors work through informal networks to provide sex education and family planning information. Both utilization and the cost of these services are examined in the context of plans for expanding coverage in Mexico-U.S. border areas.

  6. Use of alternative waste materials in producing ultra-high performance concrete

    Directory of Open Access Journals (Sweden)

    Ahmad Shamsad

    2017-01-01

    Full Text Available In a corrosive environment similar to that of the Arabian Gulf, use of high-performance concrete is one of the options to ensure a target service life of concrete structures. However, in absence of good quality coarse aggregates, it is a challenging task to produce high-performance concrete. Recently, the possibility of producing ultra-high-performance concrete (UHPC has been widely reported in the literature. UHPC is produced without coarse aggregates at very low water to cementitious materials ratio, high amounts of cement, mineral admixtures, and superplasticizer along with fine quartz sand as aggregate, quartz powder as micro-filler, a nd steel fibres for fracture toughness. In the present work, an effort was made to utilize local waste materials as alternative mineral admixtures and local dune sand as aggregate in producing different UHPC mixtures without addition of quartz powder. The mechanical properties, shrinkage, and durability characteristics of the UHPC mixtures were studied. Test results indicate that it is possible to produce UHPC mixtures using alternative waste materials, which would have targeted flow, strength, toughness, and resistance against reinforcement corrosion. The information presented in the paper would help in optimum selection of a mixture of UHPC considering the availability of local materials, exposure conditions and structural requirements.

    2016-12-01

    To characterize requests received through an academic drug information consultation service related to complementary and alternative medicines. A retrospective review and descriptive analysis of drug information consultations was conducted. A total of 195 consultations related to complementary and alternative medicine were evaluated. All consultation requests involved questions about dietary supplements. The most common request types were related to safety and tolerability (39%), effectiveness (38%), and therapeutic use (34%). Sixty-eight percent of the requests were from pharmacists. The most frequent consultation requests from pharmacists were questions related to drug interactions (37%), therapeutic use (37%), or stability/compatibility/storage (34%). Nearly 60% of complementary and alternative medicine-related consultation requests were able to be completely addressed using available resources. Among review sources, Natural Medicines Comprehensive Database, Clinical Pharmacology, Micromedex, and Pharmacist's Letter were the most common resources used to address consultations. Utilization of a drug information service may be a viable option for health care professionals to help answer a complementary and alternative medicine-related question. Additionally, pharmacists and other health care professionals may consider acquiring resources identified to consistently answering these questions. © The Author(s) 2015.

  2. Multiple-Use Services as an Alternative to Rural Water Supply Services: A Characterisation of the Approach

    Directory of Open Access Journals (Sweden)

    Stef Smits

    2010-02-01

    Full Text Available Multiple-use services (MUS have recently gained increased attention as an alternative form of providing rural water services in an integrated manner. This stems from the growing recognition that users anyway tend to use water systems for multiple purposes. This paper aims to characterise this practice on the basis of case evidence collected in eight countries in Africa, Asia and Latin America. The cases show that people almost universally use water for both domestic and productive activities at and around the homestead. Although seldom the main source of people’s income or food production, these activities are of considerable importance for people’s livelihoods. The extent to which people use water for multiple purposes is closely related to the level of access to water expressed in the form of a water ladder in this paper. The case studies presented demonstrate how access is created by different types and combinations of well-known technologies. Additional financial and management measures are required to ensure sustainability of services. Despite the practical feasibility of the MUS approach, it is not yet widely applied by service providers and sector agencies due to observed barriers in institutional uptake. A better characterisation of MUS, alongside a learning-driven stakeholder process was able to overcome some of these barriers and improve the consideration of multiple uses of water in policy and practice.

  3. Alternative measure for performance of HLW geologic repository

    A repository performance model that can show effects of canister multiplicity and repository configuration has been developed. Masses of a radionuclide in the repository and in the far field are proposed as performance measures. Canister multiplicity has significant effects on the release of long-lived radionuclides from the repository. As more canisters are included in the same water stream, the radionuclide concentration in the stream increases, but becomes independent of the number of canisters for sufficiently many canisters. Effects of reduction of radionuclide mass in the repository on the repository performance are clearly observed if the canister multiplicity is taken into account and the mass-based measures are applied.

  4. Assessing the performance of mental health service facilities for meeting patient priorities and health service responsiveness.

    Bramesfeld, A; Stegbauer, C

    2016-10-01

    The World Health Organisation has defined health service responsiveness as one of the key-objectives of health systems. Health service responsiveness relates to the ability to respond to service users' legitimate expectations on non-medical issues when coming into contact with the services of a healthcare system. It is defined by the areas showing respect for persons and patient orientation. Health service responsiveness is particularly relevant to mental health services, due to the specific vulnerability of mental health patients but also because it matches what mental health patients consider as good quality of care as well as their priorities when seeking healthcare. As (mental) health service responsiveness applies equally to all concerned services it would be suitable as a universal indicator for the quality of services' performance. However, performance monitoring programs in mental healthcare rarely assess health service performance with respect to meeting patient priorities. This is in part due of patient priorities as an outcome being underrepresented in studies that evaluate service provision. The lack of studies using patient priorities as outcomes transmits into evidence based guidelines and subsequently, into underrepresentation of patient priorities in performance monitoring. Possible ways out of this situation include more intervention studies using patient priorities as outcome, considering evidence from qualitative studies in guideline development and developing performance monitoring programs along the patient pathway and on key-points of relevance for service quality from a patient perspective.

    In 2009, Blue Cross-Blue Shield of Massachusetts (BCBSMA) implemented the alternative quality contract (AQC), which pays provider organizations a global payment for all services used by enrollees. BCBSMA claims for 2006-2011 were used to compare youths enrolled in provider organizations participating in the AQC (7,407 person-years [PYs]) with those not participating (45,398 PYs). Difference-in-differences models estimated changes in mental health and substance abuse treatment service utilization and spending attributable to the AQC. The AQC was associated with small increases in the probability of any outpatient visits and in the probability and number of medication management visits among children with attention-deficit hyperactivity disorder (ADHD). Spending did not change, and there was no evidence of reductions in service utilization or spending for children with ADHD in the first three years of AQC implementation.

    In the near future, services for the nuclear power plants in operation will become particularly important. Already at the present stage, engineering firms contribute to the planning of revisions and repair work, to the design, procurement and project management of new components and subsystems, respectively; they delegate supporting engineering personnel for the execution of in-plant measures, create special EDP software, develop quality assurance systems and work on quality control. This enumeration presents a rough outline of the field of activities, although it is far from complete. Also, the lines are drawn rather artibrarily, leaving out, for instance, the extensive activities in the fields of waste management and fuel management. These are main activities of specialized engineering firms which will be the subject of a future report. (orig.) [de

  12. Operational safety system performance alternative to the WANO's indicator

    2002-01-01

    One of the operational safety performance indicators recommended by the World Association of Nuclear Operators (WANO) and adopted by Electronuclear is the reliability of the safety systems. The parameter selected to represent this indicator is the average unavailability of the trains of the concerned system. This parameter would be universally representative of the reliability for comparison purpose only if all nuclear power plants were designed within the same redundancy criteria. Considering the diversity of design criteria of the power plants in operation and based on a probabilistic approach, this paper proposes new performance indicators which are comparable regardless the redundancy criteria of the system. A case example applied to a system of the Angra 2 nuclear power plant shows that, even though with the plant in the infancy phase, the performance of the system in the period is very good. (author)

  16. Measuring the performance of G2G services in Iran

    Science.gov (United States)

    Zarei, Behrouz; Safdari, Maryam

    To highlight the growth of e-government and the importance of its services it is essential to evaluate the performance of the service delivery to customers. Research indicates that traditional performance indexes are not suitable for this evaluation; moreover, it is noticeable that the e-government services are intangible and invisible. Among different e-government services, measurement of quality government to government (G2G) services has been less attractive for researchers while crucial for government policy-makers. This calls for a better understanding of the specific needs of users of these services in order to provide appropriate type and level of services that meets those needs. In this paper, the performance of the G2G services is measured in the Iranian context. For this purpose, SERVQUAL, which is a well-known method for assessing service quality, is employed. This study proposes and tests a five-factor of SERVQUAL instrument to explain user satisfaction and gap analysis, between expectations and perceptions of its customers, consisting thirty ministries and main governmental organizations. Based on a Chi-square test, factor analysis, gap analysis and correlations, it is concluded the gap between expectations and perceptions of G2G customers is significant and customer satisfaction of G2G services is at low level.

  17. Learning and performance under alternative instructional manifestations of experimental practice

    Science.gov (United States)

    Ford, Michael J.

    Before we can understand how students learn "to do" science, we must make explicit our assumptions about what scientific practice is. This study compares the learning outcomes of two sixth-grade instructional units on experimentation, each based on a particular characterization of practice. In one unit, instruction focused on acquisition and application of the control of variables strategy (CVS; Chen & Klahr, 1999), which is consistent with a popular conception of science education, stemming from Piaget, as the mastery of logical forms. In the other unit, students designed experimental apparatus to answer a target question, and instruction emphasized practices of rendering and transforming the material world in ways that support scientific understanding. Students in both groups were assessed for CVS acquisition and subsequent experimental performance on a novel task, and group performances on these assessments different across instructional conditions. I will argue that student understandings of goals, norms of instructional expectation, and strategies explain these differences, in some cases by supporting performance and in other cases by hindering it. I will also argue that the results question the role typically attributed to logical method in learning to design experiments.

    2016-06-01

    Full Text Available Alternative service delivery (ASD is generally confined to the provision opublic services within the boundaries of a single nation state. This paper extends thisconceptualization and practice beyond a single nation state by focusing on services provided  by international regional organizations (IROs, which encompass more than a single country. Recognizing that the regional approach may not be suitable under all circumstances, the papertakes a contingency approach and discusses with illustrations the conditions under which the regional or continental approaches may provide superior public services to the wider population. Three examples from the East African Community (EAC, Africa’s riparian river basins, and cross-border illicit trade of conflict minerals in the Great Lakes region are given as illustrative cases. Noting that Africa’s growing aspirations for inclusive development and rapid transformation call for better governance and quality public services, the paper ends by calling for more scholarly work and field experiments on ASD and other models applicable at local, national, regional and continental levels.

    Purpose Measuring healthcare service quality provides an objective guide for managers and policy makers to improve their services and patient satisfaction. Consequently, the purpose of this paper is to measure service quality provided to surgical and medical inpatients at Kerman Medical Sciences University (KUMS) in 2015. Design/methodology/approach A descriptive-analytic study, using a cross-sectional method in the KUMS training hospitals, was implemented between October 2 and March 15, 2015. Using stratified random sampling, 268 patients were selected. Data were collected using an importance-performance analysis (IPA) questionnaire, which measures current performance and determines each item's importance from the patients' perspectives. These data indicate overall satisfaction and appropriate practical strategies for managers to plan accordingly. Findings Findings revealed a significant gap between service importance and performance. From the patients' viewpoint, tangibility was the highest priority (mean=3.54), while reliability was given the highest performance (mean=3.02). The least important and lowest performance level was social accountability (mean=1.91 and 1.98, respectively). Practical implications Healthcare managers should focus on patient viewpoints and apply patient comments to solve problems, improve service quality and patient satisfaction. Originality/value The authors applied an IPA questionnaire to measure service quality provided to surgical and medical ward patients. This method identifies and corrects service quality shortcomings and improving service recipient perceptions.

    Full Text Available As the global economy becomes a service oriented economy, food service accounts for over 20% of service revenue, with an annual growth rate of more than 3%. Compared to physical products, service features are invisible, and the production and sale occurs simultaneously. There is not easy to measure the performance of service. Therefore, the service quality of catering services is considered to be an important topic of service management. According Market Intelligence & Consulting Institute (MIC to apply blog text analyzing to point out top 10 restaurants of blog in Taiwan, what it’s popular restaurant in food service industries. This paper attempts to identify both the importance and performance of restaurant service quality in the Taiwan food service industry using the SERVQUAL and IPA model. We can conclude with certainty that three methods (SERVQUAL, IF and IPA are able to explain significant amount of service quality. At the same time, the service quality factors of IPA model had more comprehensive consideration in comparison to those of SERVQUAL and IF.

    Ecosystems can shift between alternative states characterized by persistent differences in structure, function, and capacity to provide ecosystem services valued by society. We examined empirical evidence for alternative states in a semiarid grassland ecosystem where topographic complexity and contrasting management regimes have led to spatial variations in levels of livestock grazing. Using an inventory data set, we found that plots (n = 72) cluster into three groups corresponding to generalized alternative states identified in an a priori conceptual model. One cluster (biocrust) is notable for high coverage of a biological soil crust functional group in addition to vascular plants. Another (grass-bare) lacks biological crust but retains perennial grasses at levels similar to the biocrust cluster. A third (annualized-bare) is dominated by invasive annual plants. Occurrence of grass-bare and annualized-bare conditions in areas where livestock have been excluded for over 30 years demonstrates the persistence of these states. Significant differences among all three clusters were found for percent bare ground, percent total live cover, and functional group richness. Using data for vegetation structure and soil erodibility, we also found large among-cluster differences in average levels of dust emissions predicted by a wind-erosion model. Predicted emissions were highest for the annualized-bare cluster and lowest for the biocrust cluster, which was characterized by zero or minimal emissions even under conditions of extreme wind. Results illustrate potential trade-offs among ecosystem services including livestock production, soil retention, carbon storage, and biodiversity conservation. Improved understanding of these trade-offs may assist ecosystem managers when evaluating alternative management strategies.

  3. EVALUATION OF HOTEL SERVICE-PERFORMANCE PROCESS IN BULGARIA

    Full Text Available The paper analyses the hotel service-performance process in Bulgarian hotels, which is based on the results of the research about tourists’ opinion on basic moments in service process. One of the most important characteristics of hotel industry is the leading role of the human factor in service-performance process. It cannot be accomplished without the participation of the customer and without the participation of the staff.This makes the evaluation of service process strongly subjective. Because of this, customer needs satisfaction is a big challenge for the hotel management. Under the present conditions of an increased competition, satisfying customers means offering service-performance process, which not only meets, but also exceeds guests’expectations. This can be achieved by a preliminary study of their requirements and expectations.

    As healthcare organizations become increasingly complex, healthcare administrators and human resource managers face the cost and challenges of employment-related disputes. Litigation and legal costs associated with employment disputes are escalating at a significant rate. Additionally, litigation procedures are drawn out and damage the employer-employee relationship. Alternative dispute resolution (ADR) programs such as mediation and arbitration alleviate the burden of litigation and preserve positive employment relationships between the organization and its employees. A proposed ADR program is presented is a guideline for health services organizations considering the adoption of such programs.

  13. Development and performance of an alternative biofilter system.

    Lee, D H; Lau, A K; Pinder, K L

    2001-01-01

    Step tracer tests were carried out on lab-scale biofilters to determine the residence time distributions (RTDs) of gases passing through two types of biofilters: a standard biofilter with vertical gas flow and a modified biofilter with horizontal gas flow. Results were used to define the flow patterns in the reactors. "Non-ideal flow" indicates that the flow reactors did not behave like either type of ideal reactor: the perfectly stirred reactor [often called a "continuously stirred tank reactor" (CSTR)] or the plug-flow reactor. The horizontal biofilter with back-mixing was able to accommodate a shorter residence time without the usual requirement of greater biofilter surface area for increased biofiltration efficiency. Experimental results indicated that the first bed of the modified biofilter behaved like two CSTRs in series, while the second bed may be represented by two or three CSTRs in series. Because of the flow baffles used in the horizontal biofilter system, its performance was more similar to completely mixed systems, and hence, it could not be modeled as a plug-flow reactor. For the standard biofilter, the number of CSTRs was found to be between 2 and 9 depending on the airflow rate. In terms of NH3 removal efficiency and elimination capacity, the standard biofilter was not as good as the modified system; moreover, the second bed of the modified biofilter exhibited greater removal efficiency than the first bed. The elimination rate increased as biofilter load increased. An opposite trend was exhibited with respect to removal efficiency.

    2007-08-01

    Full Text Available The contribution of services to the development of every national economy is in the progress,they becoming the major contributor to the gross national product of most countries. In their turn, thecustomers become more demanding and powerful in their relationship with service providers. They askfor more and new relationship. The appropriate new marketing, known as Relationship Marketing, looksto engage the customer interactively in the many steps of creating value which is later shared betweenservice provider and customer. This requires to focus on long-term customer relationship. In order toestablish and maintain long-term relationship, the relationship marketing should understand customerexpectations, know the customers, evaluate services process, obtain a proper service quality and adequatelymanage customers’ relationships. The service customer’s is placed on an expectation range to afive dimension scale and have two levels which may be analyzed into a model of service. A stimulus forrelationship marketing performance may be the quality of service. The objective and subjective quality ofservice is essential for the service customer relationship management. In order to reach the goal ofretaining actual customers, service companies should be prepared to spot customers who leave and thenanalyze and act on information they provide. Managers should make sure the entire organization understandthe importance of keeping customers and encourage employees to pursue zero defections by tryingincentives, planning, and budgeting to defections targets. Most important, managers use defections as avehicle for continuously improving the quality and value of the service they provide to customer.

  8. How to construct a service quality index in performance based ratemaking

    Energy Technology Data Exchange (ETDEWEB)

    Alexander, B.R.

    1996-04-01

    Nothing will derail the movement to competition quicker than a falloff in service quality. During the uncertain transition to a more competitive electricity market, utility regulators should carry out their duty to ensure adequate service quality by adopting innovative performance tracking methods. Despite all the talk - and there is plenty of that - the restructuring of the electric utility industry is not yet upon us. But many state regulatory bodies - having already experienced restructuring in the telecommunications industry, in which many employed new regulatory models known under the rubric of performance-based regulation - are beginning to experiment with some form of PBR in the increasingly competitive electricity industry. PBR is usually undertaken on the assumption that, in a more competitive industry, a lighter regulatory hand coupled with the discipline of market competition will produce better results for both utility customers and shareholders. PBR, as an alternative to traditional base rate regulation, typically retains strict control over basic service rates for core customers, either by freezing prices or establishing a formula that restricts the utility`s ability to raise prices for these customer groups. The utilty is usually given significant pricing and marketing flexibility over more competitive services and the ability to retain earnings from these services. A hallmark of these alternative schemes is their multi-year nature: the utility is offered the opportunity to earn higher profits over, say, a two-to-five year period, in return for stricter regulatory controls on prices charged to core customers. The purpose of this article, based in large part on the telecommunications experience, is to describe why it is necessary to address customer service issues that are inherent in PBR and to provide the basic tools to create a customer service and reliability index that can be included in any alternative rate plan for a utilty.

  10. Shifting Away From Fee-For-Service: Alternative Approaches to Payment in Gastroenterology.

    Science.gov (United States)

    Patel, Kavita; Presser, Elise; George, Meaghan; McClellan, Mark

    2016-04-01

    Fee-for-service payments encourage high-volume services rather than high-quality care. Alternative payment models (APMs) aim to realign financing to support high-value services. The 2 main components of gastroenterologic care, procedures and chronic care management, call for a range of APMs. The first step for gastroenterologists is to identify the most important conditions and opportunities to improve care and reduce waste that do not require financial support. We describe examples of delivery reforms and emerging APMs to accomplish these care improvements. A bundled payment for an episode of care, in which a provider is given a lump sum payment to cover the cost of services provided during the defined episode, can support better care for a discrete procedure such as a colonoscopy. Improved management of chronic conditions can be supported through a per-member, per-month (PMPM) payment to offer extended services and care coordination. For complex chronic conditions such as inflammatory bowel disease, in which the gastroenterologist is the principal care coordinator, the PMPM payment could be given to a gastroenterology medical home. For conditions in which the gastroenterologist acts primarily as a consultant for primary care, such as noncomplex gastroesophageal reflux or hepatitis C, a PMPM payment can support effective care coordination in a medical neighborhood delivery model. Each APM can be supplemented with a shared savings component. Gastroenterologists must engage with and be early leaders of these redesign discussions to be prepared for a time when APMs may be more prevalent and no longer voluntary.

    Chien, Chun-Cheng; Chou, Hsin-Kai; Hung, Shuo-Tsung

    2008-01-01

    Based on the conceptual framework known as the "service triangle," the authors constructed a model of nurses' goal orientation, service behavior, and service performance to investigate the antecedents and consequences of the medical service behavior provided by nurses. This cross-sectional study collected data from 127 nurses in six hospitals using a mail-in questionnaire. Analysis of the model revealed that the customer-oriented behavior of nurses had a positive influence on organizational citizenship behavior; and both of these behaviors had a significant positive influence on service performance. The results also indicate that a higher learning goal orientation among nurses was associated with the performance of both observable customer-oriented behavior and organizational-citizenship behavior.

  12. Experimental demonstration of radiation effects on the performance of a stirling-alternator convertor and candidate materials evaluation

    Science.gov (United States)

    Mireles, Omar R.

    Free-piston Stirling power convertors are under consideration by NASA for service in the Advanced Stirling Radioisotope Generator (ASRG) and Fission Surface Power (FSP) systems to enable aggressive exploration missions by providing a reliable and constant power supply. The ASRG must withstand environmental radiation conditions, while the FSP system must tolerate a mixed neutron and gamma-ray environment resulting from self-irradiation. Stirling-alternators utilize rare earth magnets and a variety of organic materials whose radiation limits dominate service life estimates and shielding requirements. The project objective was to demonstrate the performance of the alternator, identify materials that exhibit excessive radiation sensitivity, identify radiation tolerant substitutes, establish empirical dose limits, and demonstrate the feasibility of cost effective nuclear and radiation tests by selection of the appropriate personnel and test facilities as a function of hardware maturity. The Stirling Alternator Radiation Test Article (SARTA) was constructed from linear alternator components of a Stirling convertor and underwent significant pre-exposure characterization. The SARTA was operated at the Sandia National Laboratories Gamma Irradiation Facility to a dose of over 40 Mrad. Operating performance was within nominal variation, although modestly decreasing trends occurred in later runs as well as the detection of an electrical fault after the final exposure. Post-irradiation disassembly and internal inspection revealed minimal degradation of the majority of the organic components. Radiation testing of organic material coupons was conducted since the majority of the literature was inconsistent. These inconsistencies can be attributed to testing at environmental conditions vastly different than those Stirling-alternator organics will experience during operation. Samples were irradiated at the Texas A&M TRIGA reactor to above expected FSP neutron fluence. A thorough

  13. Alternate service delivery models in cancer genetic counseling: a mini-review

    Directory of Open Access Journals (Sweden)

    Adam Hudson Buchanan

    2016-05-01

    Full Text Available Demand for cancer genetic counseling has grown rapidly in recent years as germline genomic information has become increasingly incorporated into cancer care and the field has entered the public consciousness through high-profile celebrity publications. Increased demand and existing variability in the availability of trained cancer genetics clinicians place a priority on developing and evaluating alternate service delivery models for genetic counseling. This mini-review summarizes the state of science regarding service delivery models such as telephone counseling, telegenetics and group counseling. Research on comparative effectiveness of these models in traditional individual, in-person genetic counseling has been promising for improving access to care in a manner acceptable to patients. Yet, it has not fully evaluated the short- and long-term patient- and system-level outcomes that will help answer the question of whether these models achieve the same beneficial psychosocial and behavioral outcomes as traditional cancer genetic counseling. We propose a research agenda focused on comparative effectiveness of available service delivery models and how to match models to patients and practice settings. Only through this rigorous research can clinicians and systems find the optimal balance of clinical quality, ready and secure access to care, and financial sustainability. Such research will be integral to achieving the promise of genomic medicine in oncology.

  16. Performance Testing of a High Temperature Linear Alternator for Stirling Convertors

    Science.gov (United States)

    Metscher, Jonathan F.; Geng, Steven M.

    2016-01-01

    The NASA Glenn Research Center has conducted performance testing of a high temperature linear alternator (HTLA) in support of Stirling power convertor development for potential future Radioisotope Power Systems (RPS). The high temperature linear alternator is a modified version of that used in Sunpower's Advanced Stirling Convertor (ASC), and is capable of operation at temperatures up to 200 deg. Increasing the temperature capability of the linear alternator could expand the mission set of future Stirling RPS designs. High temperature Neodymium-Iron-Boron (Nd-Fe-B) magnets were selected for the HTLA application, and were fully characterized and tested prior to use. Higher temperature epoxy for alternator assembly was also selected and tested for thermal stability and strength. A characterization test was performed on the HTLA to measure its performance at various amplitudes, loads, and temperatures. HTLA endurance testing at 200 deg is currently underway.

  11. Application of Value Engineering to Improve upon Customer Services Performance in Mazandaran Water and Sewage Company

    Directory of Open Access Journals (Sweden)

    Reza Tavakkoli-Mogahddam

    2007-06-01

    Full Text Available Over the course of producing and marketing goods and services, it appears that industry faces a new challenge in which information and science form the basis for any organizational movement. In this regard, the competitive preference of the organization concentrates on customer and value creation in the organization. Value engineering recognizes product/service functions and produces those with the maximum value at the lowest cost without the loss of production or service quality and safety. In this paper, using value engineering based on the international job plan of the SAVE (Society of American Value Engineering, various alternatives are proposed to improve upon the performance of Customer Services of Water and Sewage Co. The results indicate possible savings of about 714 Million Rials for the water authority in the city of Sari and 4860 Million Rials across Mazandaran Province.

  12. Emergency medical services key performance measurement in Asian cities.

    Rahman, Nik Hisamuddin; Tanaka, Hideharu; Shin, Sang Do; Ng, Yih Yng; Piyasuwankul, Thammapad; Lin, Chih-Hao; Ong, Marcus Eng Hock

    2015-01-01

    One of the key principles in the recommended standards is that emergency medical service (EMS) providers should continuously monitor the quality and safety of their services. This requires service providers to implement performance monitoring using appropriate and relevant measures including key performance indicators. In Asia, EMS systems are at different developmental phases and maturity. This will create difficultly in benchmarking or assessing the quality of EMS performance across the region. An attempt was made to compare the EMS performance index based on the structure, process, and outcome analysis. The data was collected from the Pan-Asian Resuscitation Outcome Study (PAROS) data among few Asian cities, namely, Tokyo, Osaka, Singapore, Bangkok, Kuala Lumpur, Taipei, and Seoul. The parameters of inclusions were broadly divided into structure, process, and outcome measurements. The data was collected by the site investigators from each city and keyed into the electronic web-based data form which is secured strictly by username and passwords. Generally, there seems to be a more uniformity for EMS performance parameters among the more developed EMS systems. The major problem with the EMS agencies in the cities of developing countries like Bangkok and Kuala Lumpur is inadequate or unavailable data pertaining to EMS performance. There is non-uniformity in the EMS performance measurement across the Asian cities. This creates difficulty for EMS performance index comparison and benchmarking. Hopefully, in the future, collaborative efforts such as the PAROS networking group will further enhance the standardization in EMS performance reporting across the region.

  14. Strategic cost management, contingent factors and performance in services

    Directory of Open Access Journals (Sweden)

    Odysseas Pavlatos

    2018-06-01

    Full Text Available The purpose of this paper is to investigate the relationship between contextual factors identified from contingency-based research, the extent of the use of strategic cost management (SCM techniques and business performance in services. An empirical survey was conducted on a sample of 88 services in Greece. The analysis of the survey data indicates that the use of strategic cost management techniques in services can be considered quite satisfactory. By drawing on the grounds of contingency theory, five factors were identified as potentially exhibiting an emergent relationship with strategic cost management. The five factors are; (1 Perceived environmental uncertainty, (2 Structure, (3 Organizational life cycle stage, (4 Strategy and (5 Size. The survey revealed that SCM usage is positively affected by these five contingent factors, while SCM usage, in turn, positively affects performance. A significant mediating effect of SCM usage on performance is evident.

    Gadde, U; Kim, W H; Oh, S T; Lillehoj, Hyun S

    2017-06-01

    With the increase in regulations regarding the use of antibiotic growth promoters and the rise in consumer demand for poultry products from 'Raised Without Antibiotics' or 'No Antibiotics Ever' flocks, the quest for alternative products or approaches has intensified in recent years. A great deal of research has focused on the development of antibiotic alternatives to maintain or improve poultry health and performance. This review describes the potential for the various alternatives available to increase animal productivity and help poultry perform to their genetic potential under existing commercial conditions. The classes of alternatives described include probiotics, prebiotics, synbiotics, organic acids, enzymes, phytogenics, antimicrobial peptides, hyperimmune egg antibodies, bacteriophages, clay, and metals. A brief description of the mechanism of action, efficacy, and advantages and disadvantages of their uses are also presented. Though the beneficial effects of many of the alternatives developed have been well demonstrated, the general consensus is that these products lack consistency and the results vary greatly from farm to farm. Furthermore, their mode of action needs to be better defined. Optimal combinations of various alternatives coupled with good management and husbandry practices will be the key to maximize performance and maintain animal productivity, while we move forward with the ultimate goal of reducing antibiotic use in the animal industry.

    Full Text Available Public sector reform aims to increase performance by improving its efficiency and effectiveness by improving the quality of services provided by public service in order to maximize individual welfare of citizens. The purpose of reform is to improve public services because they have to deal with uncertainties and rapid changes that take place in the internal environmental and external pressures. Public administration, in quality of service provider must make a series of efforts to ensure that citizens know their rights and public services on witch they can benefit taking into account the simplification of service delivery, a high quality of its, new administrative procedures for allocating resources in a transparent way and informing the citizens of standards of services and of the methods of compensation in case if the provided quality is different from that promised. Most important is the fact that the local government must realize that effectiveness involves defining objectives that must be achieved simultaneously with the estimation of the results obtained.

    Full Text Available Abstract Background Bharatpur Eye Hospital in Chitwan District, a primarily agrarian setting in south-central Nepal, reduced the number of diagnostic screening and treatment (DST camps by one half (151 to 75 in an attempt to increase both the efficiency of its outreach program and the number of people that go directly to the hospital for service. The Hospital evaluated the two program models in terms of program costs, cataract surgical utilization, hospital direct payment and patient equity. Methods The study is a prospective, before and after, study of the impact of an alternate outreach model on cataract service utilization patterns and cost per outreach camp and cost per cataract surgery at Bharatpur Eye Hospital, comparing the service years July 2006 to June 2007, with July 2007 to June 2008. Study findings were based on routinely gathered hospital and outreach administrative data. Results The total cost of the DST camps decreased by approximately US$2000. The cost per camp increased from US$52 to $78 and the cost per cataract surgery decreased from US$ 3.80 to $3.20. The number of patients who went directly to the hospital, and paid for cataract surgery, increased from 432 (17% to 623 (25%. The total number of cataract surgical procedures at Bharatpur Eye Hospital remained very similar between the two service years (2501 and 2449, respectively. The presenting visual acuity and sex of the two cataract surgical populations were very similar (favouring women, 53 and 55% in the two years, respectively. A shift toward younger men and women occurred with a 245 (64% increase in people age 50-59 years, and shift away from people age 70 years and older with a 236 (22% reduction. The age and sex distribution of the direct paying patients were very similar in the two years. Conclusion The new, more concentrated, more rural DST model of service delivery reduced overall outreach program costs, cost per cataract surgery transported, while increasing

    1990-01-01

    The purpose of this study was to analyse the performance and to establish the lowest detectable occupational dose (LDOD) of the TNO TL dosemeter, in use for large scale routine individual monitoring since 1983. The TNO individual monitoring service uses three TLD reader systems and over 45000 TL dosemeters, designed to measure H s (0.07) and H p (10). Each reader system is normalised daily and each individual dosemeter is calibrated every ten readout cycles. The performance of the service is monitored by a double blind experimental set-up. A series of 10 routine dosemeters is issued every fortnight, mailed, exposed by staff not involved in the monitoring service, sent back and evaluated. The conclusion of this study is that the lowest detectable occupational dose is less than 0.04 mSv and that the integrated dose at the level of the annual dose limit is measured within 2%. (author)

    OpenAIRE

    Boyne, George A.; James, Oliver; John, Peter; Petrovsky, Nicolai

    2010-01-01

    Political and organizational theories suggest that the turnover of chief executives and other members of senior management teams are likely to be influenced by public service performance. We use a panel data set of 148 English local governments over 4 years to test this proposition. The empirical results show that performance has a negative effect on turnover, but that this effect is weaker for chief executives than for members of their senior management teams. In addition, top team turnover ...

  13. Organization structure and the performance of hospital emergency services.

    Science.gov (United States)

    Georgopoulos, B S

    1985-07-01

    A comparative study of 30 hospital emergency departments (EDs) and nearly 1,500 individuals associated with them was conducted. Data were obtained from institutional records, physicians, patients, and other sources. The object was to investigate the relationship between the organization and performance of these health service systems. The study assessed the quality of medical care, the quality of nursing care, and the economic efficiency of hospital EDs. The results show substantial interinstitutional differences in these criteria. They also show a significant relationship between medical and nursing care, but not between the quality of care and economic efficiency. Differences in ED performance are related to medical staffing patterns, medical teaching affiliation, personnel training, scope of emergency services, number of patient visits processed, and hospital size and complexity. Not all of these variables, however, correlate positively with all three criteria of performance, nor are they equally important to each.

    The claim that perceived organizational red tape hampers public services has become a central theme in public administration research. Surprisingly, however, few scholars have empirically examined the impact of perceived red tape on organizational performance. This study empirically analyzes how...... perceived organizational red tape among managers and frontline staff relates to objectively measured performance. The data consists of survey responses from teachers and principals at Danish upper secondary schools combined with grade-level administrative performance data. Based on theories of red tape...... and motivation crowding, we hypothesize that perceived organizational red tape reduces performance within such organizations. The empirical result is a small, negative relationship between staff perception of red tape and performance, and no relationship between manager-perceived red tape and performance....

    Cohen, Howard J; Van Orden, Drew R

    2008-03-01

    A study was conducted to assess historical asbestos exposures of mechanics performing clutch service on motor vehicles. For most of the 20th century, friction components used in brakes and manual transmission clutches contained approximately 25-60% chrysotile asbestos. Since the late 1960s, asbestos exposure assessment studies conducted on mechanics performing brake service have frequently reported levels below the current OSHA permissible exposure limit (PEL) of 0.1 fiber/cc (flcc). Although there is a robust asbestos exposure data set for mechanics performing brake service, there are almost no data for mechanics removing and replacing clutches in manual transmission vehicles. Personal and area airborne asbestos samples were collected during the removal of asbestos-containing clutches from 15 manual transmissions obtained from salvage facilities by an experienced mechanic. Clutch plates and debris were analyzed for asbestos using EPA and ISO published analytical methods. More than 100 personal and area air samples were collected and analyzed for asbestos fibers using NIOSH methods 7400 and 7402. A separate study involved a telephone survey of 16 automotive mechanics who began work prior to 1975. The mechanics were asked about the duration, frequency, and methods used to perform clutch service. Wear debris in the bell housing surrounding clutches had an average of 0.1% chrysotile asbestos by weight, a value consistent with similar reports of brake debris. Asbestos air sampling data collected averaged 0.047 flcc. Mechanics participating in the telephone survey indicated that clutch service was performed infrequently, the entire clutch assembly was normally replaced, and there was no need to otherwise handle the asbestos-containing clutch plates. These mechanics also confirmed that wet methods were most frequently used to clean debris from the bell housing. Combining the asbestos exposure that occurred when mechanics performed clutch service, along with the duration

    Internet of Things (IoT) is the next wave of industry revolution that will initiate many services, such as personal health care and green energy monitoring, which people may subscribe for their convenience. Recommending IoT services to the users based on objects they own will become very crucial for the success of IoT. In this work, we introduce the concept of service recommender systems in IoT by a formal model. As a first attempt in this direction, we have proposed a hyper-graph model for IoT recommender system in which each hyper-edge connects users, objects, and services. Next, we studied the usefulness of traditional recommendation schemes and their hybrid approaches on IoT service recommendation (IoTSRS) based on existing well known metrics. The preliminary results show that existing approaches perform reasonably well but further extension is required for IoTSRS. Several challenges were discussed to point out the direction of future development in IoTSR.

    This study theorized and examined the influence of the interaction between Service-Oriented high-performance work systems (HPWSs) and service leadership on collective customer knowledge and service climate. Using a sample of 569 employees and 142 managers in footwear retail stores, we found that Service-Oriented HPWSs and service leadership reduced the influences of one another on collective customer knowledge and service climate, such that the positive influence of service leadership on collective customer knowledge and service climate was stronger when Service-Oriented HPWSs were lower than when they were higher or the positive influence of Service-Oriented HPWSs on collective customer knowledge and service climate was stronger when service leadership was lower than when it was higher. We further proposed and found that collective customer knowledge and service climate were positively related to objective financial outcomes through service performance. Implications for the literature and managerial practices are discussed. (c) 2015 APA, all rights reserved).

    Full Text Available In today’s business life, employees from different sectors have the opportunity to work in other industries and can have different positions through the organization. This can be considered from the perspective of skill transfer (transfer of tacit knowledge. The success can be questioned in terms of company performance. If this process can be managed well performance will be higher. This research mainly aims to identify whether veterans with military service experience can contribute to employee motivation, organizational motivation and organizational benefits. In order to test the assumed associations, the research employs a survey study on the veterans who have served for Bosnian army and are currently employees of Bosnian firms. The results provide that military service experience is significantly influential on the motivations of employees and organizations and on company performance. It can be suggested that the adaptation of external knowledge (skill transfer, military service experience, into new organizational environment can be enhanced by the help of knowledge management. This research is valuable in that it is among the few studies in its respective field and in the region.

  8. ANALYSING PERFORMANCE ASSESSMENT IN PUBLIC SERVICES: HOW USEFUL IS THE CONCEPT OF A PERFORMANCE REGIME?

    Martin, Steve; Nutley, Sandra; Downe, James; Grace, Clive

    2016-03-01

    Approaches to performance assessment have been described as 'performance regimes', but there has been little analysis of what is meant by this concept and whether it has any real value. We draw on four perspectives on regimes - 'institutions and instruments', 'risk regulation regimes', 'internal logics and effects' and 'analytics of government' - to explore how the concept of a multi-dimensional regime can be applied to performance assessment in public services. We conclude that the concept is valuable. It helps to frame comparative and longitudinal analyses of approaches to performance assessment and draws attention to the ways in which public service performance regimes operate at different levels, how they change over time and what drives their development. Areas for future research include analysis of the impacts of performance regimes and interactions between their visible features (such as inspections, performance indicators and star ratings) and the veiled rationalities which underpin them.

However, these tasks are also sensitive to nonfrontal lesions, and cognitive processes such as the induction of rule-learning strategies also are needed in order to perform well on these tasks. Performance on DA and OA tasks was explored in 10 patients with alcohol-induced persisting amnestic disorder (Korsakoff’s syndrome, 11 abstinent long-term alcoholics, and 13 healthy non-alcoholic controls under each of two rule provision conditions: Alternation Rule and Correction Rule. Results confirmed that rule knowledge is a crucial cognitive component for solving problems such as DA and OA, and therefore, that errors on these tasks are not due to defective response inhibition alone. Further, rule-induction strategies were helpful to Korsakoff patients, despite their poorer performance on the tasks. These results stress the role of multiple cognitive abilities in successful performance on rule induction tasks. Evidence that these cognitive abilities are served by diffusely distributed neural networks should be considered when interpreting behavioral impairments on these tasks.Keywords: alcoholism, Korsakoff’s syndrome, comparative neuropsychology, perseveration, rule induction, working memory

  10. Impact of alternative fuels on the operational and environmental performance of a small turbofan engine

    Gaspar, R.M.P.; Sousa, J.M.M.

    2016-01-01

    Highlights: • A wide range of alternative fuels is studied in a small two-spool turbofan engine. • Impact of fuel properties on flame temperature and droplet evaporation considered. • Performance and pollutant emissions at different operating conditions are analyzed. • Use of alternative fuels generally leads to an improved performance of the engine. • Mostly reductions in soot emissions, but also cuts in NO_x and CO, are obtained. - Abstract: A wide range of alternative jet fuels is studied in this work for use in a small two-spool turbofan engine. These embrace the five production pathways currently approved by the American Society for Testing and Materials. Both neat products and blends (within certified limits) have been considered. The present analysis is based on a 0-D thermodynamic modeling of the aero-engine for off-design and transient simulations. In addition, the selected approach incorporates fuel effects on combustion and the impact of fuel properties on the flame temperature, as well as on the droplet evaporation rate. Predicted performance and pollutant emission outputs for the alternative fuels are presented at different operating conditions, namely: take-off, top of climb, cruise, low power and ground idle. The results are discussed and comprehensively compared with data available in the literature. It was concluded that the combustion of alternative fuels generally leads to enhancements in engine performance with respect to the use of conventional kerosene. Reductions in pollutant emissions occur mostly in soot, but also in nitrogen oxides and carbon monoxide, depending on the fuel and operating conditions. In contrast, increased emissions of unburned hydrocarbons are generally observed. Concerns about the aero-engine dynamic response are raised only in very few cases, involving the use of neat products.

These services are based on parametric data rapidly provided by 66 seismological networks which are automatically merged and processed at EMSC. A web page which is updated every minute displays a list and a map of the latest earthquakes as well as additional information like location maps, moment tensors solutions or past regional seismicity. Since 2004, the performances and the popularity of these services have dramatically increased. The number of messages received from the contributors and the number of published events have been multiplied by 2 since 2004 and by 1.6 since 2005 respectively. The web traffic and the numbers of users of the Earthquake Notification Service (ENS) have been multiplied by 15 and 7 respectively. In terms of performances of the ENS, the median dissemination time for Euro-Med events is minutes in 2008. In order to further improve its performances and especially the speed and robustness of the reception of real time data, EMSC has recently implemented a software named QWIDS (Quake Watch Information Distribution System) which provides a quick and robust data exchange system through permanent TCP connections. At the difference with emails that can sometimes be delayed or lost, QWIDS is an actual real time communication system that ensures the data delivery. In terms of hardware, EMSC imple-mented a high availability, dynamic load balancing, redundant and scalable web servers infrastructure, composed of two SUN T2000 and one F5 BIG-IP switch. This will allow coping with constantly increas-ing web traffic and the occurrence of huge peaks of traffic after widely felt earthquakes.

    Alternate aviation fuels for military or commercial use are required to satisfy MIL-DTL-83133F(2008) or ASTM D 7566 (2010) standards, respectively, and are classified as "drop-in" fuel replacements. To satisfy legacy issues, blends to 50% alternate fuel with petroleum fuels are certified individually on the basis of processing and assumed to be feedstock agnostic. Adherence to alternate fuels and fuel blends requires "smart fueling systems" or advanced fuel-flexible systems, including combustors and engines, without significant sacrifice in performance or emissions requirements. This paper provides preliminary performance (Part A) and emissions and particulates (Part B) combustor sector data. The data are for nominal inlet conditions at 225 psia and 800 F (1.551 MPa and 700 K), for synthetic-paraffinic-kerosene- (SPK-) type (Fisher-Tropsch (FT)) fuel and blends with JP-8+100 relative to JP-8+100 as baseline fueling. Assessments are made of the change in combustor efficiency, wall temperatures, emissions, and luminosity with SPK of 0%, 50%, and 100% fueling composition at 3% combustor pressure drop. The performance results (Part A) indicate no quantifiable differences in combustor efficiency, a general trend to lower liner and higher core flow temperatures with increased FT fuel blends. In general, emissions data (Part B) show little differences, but with percent increase in FT-SPK-type fueling, particulate emissions and wall temperatures are less than with baseline JP-8. High-speed photography illustrates both luminosity and combustor dynamic flame characteristics.

    The Model 9975 shipping package specifies the materials of construction for its various components. With the loss of availability of material for two components (cane fiberboard overpack and Viton(reg s ign) GLT O-rings), alternate materials of construction were identified and approved for use for transport (softwood fiberboard and Viton(reg s ign) GLT-S O-rings). As these shipping packages are part of a long-term storage configuration at the Savannah River Site, additional testing is in progress to verify satisfactory long-term performance of the alternate materials under storage conditions. The test results to date can be compared to comparable results on the original materials of construction to draw preliminary conclusions on the performance of the replacement materials.

    This study aimed to develop a new casemix classification system as an alternative method for the budget allocation of oral healthcare service (OHCS). Initially, the International Statistical of Diseases and Related Health Problem, 10th revision, Thai Modification (ICD-10-TM) related to OHCS was used for developing the software "Grouper". This model was designed to allow the translation of dental procedures into eight-digit codes. Multiple regression analysis was used to analyze the relationship between the factors used for developing the model and the resource consumption. Furthermore, the coefficient of variance, reduction in variance, and relative weight (RW) were applied to test the validity. The results demonstrated that 1,624 OHCS classifications, according to the diagnoses and the procedures performed, showed high homogeneity within groups and heterogeneity between groups. Moreover, the RW of the OHCS could be used to predict and control the production costs. In conclusion, this new OHCS casemix classification has a potential use in a global decision making.

    Treatment effectiveness holds considerable importance in the association between service quality and satisfaction in medical service studies. While complementary and alternative medicine (CAM) use grows more prominent, comprehensive evaluations of the quality of medical service at CAM-oriented hospitals are scarce. This study assesses the quality of medical services provided at a CAM-oriented hospital of Korean medicine using the service encounter system approach and analyzes the influence of treatment effectiveness on patient loyalty. A survey study using one-on-one interviews was conducted using a cross-sectional design in outpatients visiting one of fifteen Korean medicine facilities located throughout Korea. A total of 880 surveys were completed from June to July, 2014, and 728 surveys were included in the final analysis after excluding incomplete or incorrect questionnaires. The reliability and validity of the surveys was confirmed using Cronbach's alpha coefficient and confirmatory factor analysis, and a structural equation modeling analysis was performed to verify causality and association between factors (quality of medical service, treatment effectiveness, patient satisfaction, and intent to revisit). The measured factors of physician performance and quality of service procedures had a positive effect on treatment effectiveness. The impression of the facilities and environment directly impacted satisfaction rates for interpersonal-based medical service encounters, while treatment effectiveness positively affected satisfaction regarding quality of medical service. However, treatment effectiveness had a more significant effect on satisfaction compared to facilities and environment, and it indirectly affected satisfaction and directly influenced intent to revisit. Treatment effectiveness and satisfaction both positively influenced intent to revisit. The importance of treatment effectiveness should be recognized when examining quality of medical services, and

    Decision-analytic models are routinely used as a framework for cost-effectiveness analyses of health care services and technologies; however, these models mostly ignore resource constraints. In this study, we use a discrete-event simulation model to inform a cost-effectiveness analysis of alternative options for the organization and delivery of clinical services in the ophthalmology department of a public hospital. The model is novel, given that it represents both disease outcomes and resource constraints in a routine clinical setting. A 5-year discrete-event simulation model representing glaucoma patient services at the Royal Adelaide Hospital (RAH) was implemented and calibrated to patient-level data. The data were sourced from routinely collected waiting and appointment lists, patient record data, and the published literature. Patient-level costs and quality-adjusted life years were estimated for a range of alternative scenarios, including combinations of alternate follow-up times, booking cycles, and treatment pathways. The model shows that a) extending booking cycle length from 4 to 6 months, b) extending follow-up visit times by 2 to 3 months, and c) using laser in preference to medication are more cost-effective than current practice at the RAH eye clinic. The current simulation model provides a useful tool for informing improvements in the organization and delivery of glaucoma services at a local level (e.g., within a hospital), on the basis of expected effects on costs and health outcomes while accounting for current capacity constraints. Our model may be adapted to represent glaucoma services at other hospitals, whereas the general modeling approach could be applied to many other clinical service areas.

Subgroup analyses for those aged 80–89 years were performed due to significant differences in the mean ages of the study groups. Test–retest reliability for alternating forearm movements was studied in 11 patients (mean age 80.3 ± 6.7 years and 10 controls (mean age 87.4 ± 1.6 years. Pulses generated were transformed to an analog signal shown on a modified electrocardiogram. Numbers of cycles at 10 and 15 seconds were calculated for the right and left hand. Walking 2 × 15 m and the Get-Up-and Go (GUG test were performed at self-selected and maximal speed. Associations between tests of upper and lower extremity function were sought in eight patients (mean age 85 ± 2.7 years and 16 controls (mean age 85.1 ± 2.8 years and also according to types of dementia in nine patients with probable Alzheimer's disease and 10 patients with other types of dementia.Results: Patients with dementia could perform the test and had significantly fewer cycles (P = 0.02–0.006 at both 10 and 15 seconds compared with controls after age adjustment. A higher number of cycles was associated with higher self-selected walking speeds in patients (r = -0.79. Test–retest reliability for alternating forearm movements was high for both patients (intraclass correlation 0.88–0.94 and controls (intraclass correlation 0.74–0.94.Conclusion: Alternating forearm movements at fast speed can be used as a reliable test in both

Besides that, an alternative resin, castor oil-based polyurethane, was used to bond the particles, due to the better environmental performance when compared to other resins commonly used worldwide in OSB production. Physical properties such as the moisture content, thickness swelling, and water absorption, both after 2 and 24 hours of water immersion, and mechanical properties such as the modulus of elasticity and resistance in static bending, in major and minor axes, and internal bonding were investigated. All tests were performed according to European code EN 300:2006. Results showed the influence of wood species on physical and mechanical properties. Panels made with higher density woods such as Cambará presented better physical performance, while those made with lower density woods such as Pinus presented better mechanical properties. Besides that, strand particle geometry was also influenced on all physical and mechanical properties investigated. Therefore, the feasibility of using alternative species and wood from first thinning and with castor oil-based polyurethane resin in OSB production was verified.

    1997-01-01

    Chemical processing of nuclear fuels and targets at Savannah River Site resulted in generation of millions of gallons of liquid wastes. The wastes were further processed to reduce volume and allow for extended temporary storage of a more concentrated material. Waste evaporators have been a central point for waste reduction for many years. Currently, the transfer and processing of the concentrated wastes for permanent storage requires dilution and results in generation of significant quantities of additional liquid wastes. A new round of volume reduction is required to fit existing storage capacity and to allow for removal of older vessels from service. Evaporator design, performance and repairs are discussed in this report

    This paper presents the development and evaluation of a method for enabling quantitative and automatic scoring of alternating tapping performance of patients with Parkinson's disease (PD). Ten healthy elderly subjects and 95 patients in different clinical stages of PD have utilized a touch-pad handheld computer to perform alternate tapping tests in their home environments. First, a neurologist used a web-based system to visually assess impairments in four tapping dimensions ('speed', 'accuracy', 'fatigue' and 'arrhythmia') and a global tapping severity (GTS). Second, tapping signals were processed with time series analysis and statistical methods to derive 24 quantitative parameters. Third, principal component analysis was used to reduce the dimensions of these parameters and to obtain scores for the four dimensions. Finally, a logistic regression classifier was trained using a 10-fold stratified cross-validation to map the reduced parameters to the corresponding visually assessed GTS scores. Results showed that the computed scores correlated well to visually assessed scores and were significantly different across Unified Parkinson's Disease Rating Scale scores of upper limb motor performance. In addition, they had good internal consistency, had good ability to discriminate between healthy elderly and patients in different disease stages, had good sensitivity to treatment interventions and could reflect the natural disease progression over time. In conclusion, the automatic method can be useful to objectively assess the tapping performance of PD patients and can be included in telemedicine tools for remote monitoring of tapping.

    Multitasking is associated with the generation of stimulus-locked theta (4-7 Hz) oscillations arising from prefrontal cortex (PFC). Transcranial alternating current stimulation (tACS) is a non-invasive brain stimulation technique that influences endogenous brain oscillations. Here, we investigate whether applying alternating current stimulation within the theta frequency band would affect multitasking performance, and explore tACS effects on neurophysiological measures. Brief runs of bilateral PFC theta-tACS were applied while participants were engaged in a multitasking paradigm accompanied by electroencephalography (EEG) data collection. Unlike an active control group, a tACS stimulation group showed enhancement of multitasking performance after a 90-minute session (F1,35 = 6.63, p = 0.01, ηp2 = 0.16; effect size = 0.96), coupled with significant modulation of posterior beta (13-30 Hz) activities (F1,32 = 7.66, p = 0.009, ηp2 = 0.19; effect size = 0.96). Across participant regression analyses indicated that those participants with greater increases in frontal theta, alpha and beta oscillations exhibited greater multitasking performance improvements. These results indicate frontal theta-tACS generates benefits on multitasking performance accompanied by widespread neuronal oscillatory changes, and suggests that future tACS studies with extended treatments are worth exploring as promising tools for cognitive enhancement.

  12. Random spectrum loading of dental implants: An alternative approach to functional performance assessment.

    Shemtov-Yona, K; Rittel, D

    2016-09-01

    The fatigue performance of dental implants is usually assessed on the basis of cyclic S/N curves. This neither provides information on the anticipated service performance of the implant, nor does it allow for detailed comparisons between implants unless a thorough statistical analysis is performed, of the kind not currently required by certification standards. The notion of endurance limit is deemed to be of limited applicability, given unavoidable stress concentrations and random load excursions, that all characterize dental implants and their service conditions. We propose a completely different approach, based on random spectrum loading, as long used in aeronautical design. The implant is randomly loaded by a sequence of loads encompassing all load levels it would endure during its service life. This approach provides a quantitative and comparable estimate of its performance in terms of lifetime, based on the very fact that the implant will fracture sooner or later, instead of defining a fatigue endurance limit of limited practical application. Five commercial monolithic Ti-6Al-4V implants were tested under cyclic, and another 5 under spectrum loading conditions, at room temperature and dry air. The failure modes and fracture planes were identical for all implants. The approach is discussed, including its potential applications, for systematic, straightforward and reliable comparisons of various implant designs and environments, without the need for cumbersome statistical analyses. It is believed that spectrum loading can be considered for the generation of new standardization procedures and design applications. Copyright © 2016 Elsevier Ltd. All rights reserved.

  13. Lightweight Provenance Service for High-Performance Computing

    Dai, Dong; Chen, Yong; Carns, Philip; Jenkins, John; Ross, Robert

    2017-09-09

    Provenance describes detailed information about the history of a piece of data, containing the relationships among elements such as users, processes, jobs, and workflows that contribute to the existence of data. Provenance is key to supporting many data management functionalities that are increasingly important in operations such as identifying data sources, parameters, or assumptions behind a given result; auditing data usage; or understanding details about how inputs are transformed into outputs. Despite its importance, however, provenance support is largely underdeveloped in highly parallel architectures and systems. One major challenge is the demanding requirements of providing provenance service in situ. The need to remain lightweight and to be always on often conflicts with the need to be transparent and offer an accurate catalog of details regarding the applications and systems. To tackle this challenge, we introduce a lightweight provenance service, called LPS, for high-performance computing (HPC) systems. LPS leverages a kernel instrument mechanism to achieve transparency and introduces representative execution and flexible granularity to capture comprehensive provenance with controllable overhead. Extensive evaluations and use cases have confirmed its efficiency and usability. We believe that LPS can be integrated into current and future HPC systems to support a variety of data management needs.

    2009-09-01

    Full Text Available Probiotics and prebiotics were compared to antimicrobials as alternative growth promoters in male broilers grown from 1 to 42 days of age. Eight treatments were evaluated: a control feed without antimicrobials or alternative growth promoters, a control feed with antimicrobials, a control feed with the antimicrobials colistine and avilamicine, three rations with probiotic Bacillus subtilis in different concentrations and/or under recommended usage, one ration with probiotic Saccharomyces cerevisiae in addition to a mixture of probiotic Bacillus subtilis, Saccharomyces cerevisiae and Aspergillus oryzae, and one ration with mananoligossacarids (MOS plus betaglutanes. Antimicrobials and alternative growth promoters were added to an initial feed and to a growth feed common to all birds. Thirteen to 17 replicates of 50 birds of a Cobb line were utilized per treatment in a completely randomized design. Feed consumption, feed conversion and production costs did not significantly differ among treatments. The weights of 42-day-old birds fed on Bacillus subtilis (1,6 x 109CFU/g or the mixture of probiotics were higher or similar to the weights of birds fed on ration with antimicrobials. It was concluded that probiotics can replace antimicrobials as growth promoters for broilers up to 42 days of age without negative effects on growth performance and production cost.

    The aim of this study was to describe the current state of home visit nursing services in the Korean context and to suggest future policy directions. First, the three home visit nursing services that have developed in Korea are compared using the analytic framework provided by Gilbert and Terrell in 2012. The framework is based on four dimensions of social welfare: users, services, source of funds, and service delivery process. Second, we perform a strength, weakness, opportunity, and threat analysis to suggest comprehensive and constructive home visit nursing service policies for the future. Specifically, we advocate the creation of an organization that steers the central government to operate an integrated management organization to distribute services and reduce redundancy for preventing the waste of both medical and state financial resources. This study also recommends the development of educational programs to improve the quality of services and service evaluation criteria for the objective assessment of those services. These policy guidelines may prove useful both for Korea and for other countries that intend to prepare or revise their home visit nursing service systems. © 2014 Wiley Periodicals, Inc.

    2016-12-01

    Needs and service performance assessment are key components in improving recovery among individuals with mental disorders. To test the role of service performance as a mediating factor between severity of patients' needs and outcomes. A total of 339 adults with mental disorders were interviewed. A mediation analysis between severity of needs, service performance (adequacy of help, continuity of care and recovery orientation of services) and outcomes (personal recovery and quality of life) was carried out using structural equation modelling. The structural equation model provided a good fit with the data. An increase in needs was associated with lower service performance and worse outcomes, whereas higher service performance was associated with better outcomes. Service performance partially mediated the effect of patient needs on outcomes. Poorer service performance has a negative impact on outcomes for patients with the highest needs. Ensuring more efficient services for patients with high needs may help improve their recovery and quality of life. © The Royal College of Psychiatrists 2016.

    Kolos, S; Boutsioukis, G; Hauser, R

    2012-01-01

    The ATLAS[1] experiment is operated by a highly distributed computing system which is constantly producing a lot of status information which is used to monitor the experiment operational conditions as well as to assess the quality of the physics data being taken. For example the ATLAS High Level Trigger(HLT) algorithms are executed on the online computing farm consisting from about 1500 nodes. Each HLT algorithm is producing few thousands histograms, which have to be integrated over the whole farm and carefully analyzed in order to properly tune the event rejection. In order to handle such non-physics data the Information Service (IS) facility has been developed in the scope of the ATLAS Trigger and Data Acquisition (TDAQ)[2] project. The IS provides a high-performance scalable solution for information exchange in distributed environment. In the course of an ATLAS data taking session the IS handles about a hundred gigabytes of information which is being constantly updated with the update interval varying from a second to a few tens of seconds. IS provides access to any information item on request as well as distributing notification to all the information subscribers. In the latter case IS subscribers receive information within a few milliseconds after it was updated. IS can handle arbitrary types of information, including histograms produced by the HLT applications, and provides C++, Java and Python API. The Information Service is a unique source of information for the majority of the online monitoring analysis and GUI applications used to control and monitor the ATLAS experiment. Information Service provides streaming functionality allowing efficient replication of all or part of the managed information. This functionality is used to duplicate the subset of the ATLAS monitoring data to the CERN public network with a latency of a few milliseconds, allowing efficient real-time monitoring of the data taking from outside the protected ATLAS network.

    This study is part of the Project on Alternative Systems Study, PASS, with the overall aim to perform a technical/economical ranking of alternative repository concepts and canisters for the final storage of spent nuclear fuel. The comparison should in the first stage separately assess technology in construction and operation, long-term performance and safety, and costs. Three of the repository concepts are assumed to be located at a depth of approximately 500 m in the host rock, KBS-3, Very Long Holes (VLH) and Medium Long Holes (MLH). In the KBS-3 concept the canisters are deposited in vertical deposition holes in a system of parallel storage tunnels. In the VLH concept larger canisters are deposited in long horizontal tunnels. The MLH concept, is an evolution of the two other concepts, with KBS-3 type canisters deposited in horizontal tunnels. Smaller canisters are to be deposited in deep bore holes at a depth between 2000 to 4000 m in the Very Deep Holes (VDH) concept. In all concepts the canisters will be surrounded by a bentonite buffer. The aim of the present study is to analyze and compare the performance and long-term safety of the repository concepts. Only a qualitative comparison of the concepts is made as no calculations of radionuclide releases or dose to man have been performed. The ranking of the repository concepts was carried out by comparing the VDH, VLH and MLH concept with the KBS-3 concept. The performance and long-term safety of the repositories located at 500 m level will be based on a multiple barrier system and the predictions for the concepts will involve similar uncertainties.

  5. Sustainable covers for uranium mill tailings, USA: alternative design, performance, and renovation - 16369

    International Nuclear Information System (INIS)

    Waugh, William J.; Benson, Craig H.; Albright, William H.

    2009-01-01

    The U.S. Department of Energy Office of Legacy Management is investigating alternatives to conventional cover designs for uranium mill tailings. A cover constructed in 2000 near Monticello, Utah, USA, was a redundant design with a conventional low-conductivity composite cover overlain with an alternative cover designed to mimic the natural soil water balance as measured in nearby undisturbed native soils and vegetation. To limit percolation, the alternative cover design relies on a 160-cm layer of sandy clay loam soil overlying a 40- cm sand capillary barrier for water storage, and a planting of native sagebrush steppe vegetation to seasonally release soil water through evapotranspiration (ET). Water balance monitoring within a 3.0-ha drainage lysimeter, embedded in the cover during construction, provided convincing evidence that the cover has performed well over a 9-year period (2000- 2009). The total cumulative percolation, 4.8 mm (approximately 0.5 mm yr -1 ), satisfied a regulatory goal of -1 . Most percolation can be attributed to the very wet winter and spring of 2004-2005, when soil water content exceeded the storage capacity of the cover. Diversity, percent cover, and leaf area of vegetation increased over the monitoring period. Field and laboratory evaluations several years after construction show that soil structural development, changes in soil hydraulic properties, and development of vegetation patterns have not adversely impacted cover performance. A new test facility was constructed in 2008 near Grand Junction, Colorado, USA, to evaluate low-cost methods for renovating or transforming conventional covers into more sustainable ET covers.

    Full Text Available The present study was carried out to evaluate the effects of alternative feedstuffs as partial substitutes of corn and soybean in free-range broiler diets on performance, carcass yield and technical-economic viability. A total of 400 Pescoço Pelado broilers were distributed in a completely randomized experimental design (CRD, with four treatments (treatment 1:Control; treatment 2: 10% rice bran inclusion; treatment 3: 10% ground cassava leaves; and treatment 4: 10% ground lead tree hay with four replicates per treatment. Each replicate consisted of a group of 25 birds per paddock, separated per sex. Initial weight (IW, final weight (FW, body weight (BW, daily weight gain (DWG, feed intake (FI and feed conversion ratio (FCR were evaluated. Carcass, cuts (breast, thigh, drumstick, back, neck, leg and wings, abdominal fat and giblets (gizzard, heart and liver yields were determined. The technical-economic viability of each treatment was assessed by determining the cost of feed per kg body weight, economic efficiency index and cost. The highest final weights were obtained with the use of rice bran. Rice bran and cassava leaves promoted higher carcass yield, as well as lower back and abdominal fat yields. The use of cassava leaves showed better economic efficiency among the treatments with alternative feedstuffs. The use of alternative feedstuffs at 10% inclusion in substitution of corn and soybean meal did not not result in major changes in performance and carcass parameters, and economic efficiency, and therefore, their use is recommended when the availability or the price of key ingredients, such as soybean meal and corn, increase.

  7. Non-Dam Alternatives for Delivering Water Services at Least Cost and Risk

    Directory of Open Access Journals (Sweden)

    Michael P. Totten

    2010-06-01

    We present evidence that a value-adding and risk-minimising water planning process can be achieved by shifting from the conventional focus on supply expansion to one that concentrates on efficiently delivering services at and near the point of use. The State of California has two decades of experience with this approach, demonstrating that market-based policy and regulatory innovations can unleash efficiency gains resulting in more utility water services and energy services delivered with less supply expansion at lower costs, while minimising climate-change risk, pollution and the social cost that accompany large infrastructural projects. Efficiency in delivered water services could be accomplished with investments in the range of US$10-25 billion annually, while obviating the need for spending hundreds of billions of dollars on more expensive hydropower and related infrastructural expansion projects. The shift to a regulatory system that encompasses cost-effective end-use efficiency improvements in delivering water and energy services could eliminate the need for an estimated half of all proposed dams globally, thus allowing for the maintenance of other ecosystem service benefits and offer the best hopes of meeting basic human needs for water at a more achievable level of investment.

  9. Alternative test method to assess the energy performance of frost-free refrigerating appliances

    International Nuclear Information System (INIS)

    Hermes, Christian J.L.; Melo, Cláudio; Knabben, Fernando T.

    2013-01-01

    This paper outlines an alternative test method to evaluate the energy consumption of frost-free refrigerators and freezers for residential applications. While the standardized methods require the refrigerating appliance to be kept running according to its onboard control system, which usually drives the refrigerator through an on–off cycling pattern, the proposed approach assesses the refrigerator energy performance in the steady-state regime, being therefore much faster and more reliable. In this procedure, the cooling capacity is matched to the cooling loads by PID-controlled electrical heaters installed within the refrigerated compartments, so that the compartment temperatures are kept at the desired standardized levels. Comparisons between the experimental results obtained using the steady-state energy test and the standardized procedures showed that the former follows closely the trends observed for the latter. - Highlights: ► An alternative test method to assess the energy consumption of refrigerators is proposed. ► PID-controlled electrical heaters were installed within the compartments. ► Steady-state and ISO energy tests were performed and compared. ► Both proposed and standardized test procedures showed similar trends.

So for some of them, calibration is nece...

  11. Performance Optimization of Alternative Lower Global Warming Potential Refrigerants in Mini-Split Room Air Conditioners

    Energy Technology Data Exchange (ETDEWEB)

    Shen, Bo [ORNL; Abdelaziz, Omar [ORNL; Shrestha, Som S [ORNL

    2017-01-01

    Oak Ridge National laboratory (ORNL) recently conducted extensive laboratory, drop-in investigations for lower Global Warming Potential (GWP) refrigerants to replace R-22 and R-410A. ORNL studied propane, DR-3, ARM-20B, N-20B and R-444B as lower GWP refrigerant replacement for R-22 in a mini-split room air conditioner (RAC) originally designed for R-22; and, R-32, DR-55, ARM-71A, and L41-2, in a mini-split RAC designed for R-410A. We obtained laboratory testing results with very good energy balance and nominal measurement uncertainty. Drop-in studies are not enough to judge the overall performance of the alternative refrigerants since their thermodynamic and transport properties might favor different heat exchanger configurations, e.g. cross-flow, counter flow, etc. This study compares optimized performances of individual refrigerants using a physics-based system model tools. The DOE/ORNL Heat Pump Design Model (HPDM) was used to model the mini-split RACs by inputting detailed heat exchangers geometries, compressor displacement and efficiencies as well as other relevant system components. The RAC models were calibrated against the lab data for each individual refrigerant. The calibrated models were then used to conduct a design optimization for the cooling performance by varying the compressor displacement to match the required capacity, and changing the number of circuits, refrigerant flow direction, tube diameters, air flow rates in the condenser and evaporator at 100% and 50% cooling capacities. This paper compares the optimized performance results for all alternative refrigerants and highlights best candidates for R-22 and R-410A replacement.

  12. Automatic and Objective Assessment of Alternating Tapping Performance in Parkinson’s Disease

    2013-12-01

    Full Text Available This paper presents the development and evaluation of a method for enabling quantitative and automatic scoring of alternating tapping performance of patients with Parkinson’s disease (PD. Ten healthy elderly subjects and 95 patients in different clinical stages of PD have utilized a touch-pad handheld computer to perform alternate tapping tests in their home environments. First, a neurologist used a web-based system to visually assess impairments in four tapping dimensions (‘speed’, ‘accuracy’, ‘fatigue’ and ‘arrhythmia’ and a global tapping severity (GTS. Second, tapping signals were processed with time series analysis and statistical methods to derive 24 quantitative parameters. Third, principal component analysis was used to reduce the dimensions of these parameters and to obtain scores for the four dimensions. Finally, a logistic regression classifier was trained using a 10-fold stratified cross-validation to map the reduced parameters to the corresponding visually assessed GTS scores. Results showed that the computed scores correlated well to visually assessed scores and were significantly different across Unified Parkinson’s Disease Rating Scale scores of upper limb motor performance. In addition, they had good internal consistency, had good ability to discriminate between healthy elderly and patients in different disease stages, had good sensitivity to treatment interventions and could reflect the natural disease progression over time. In conclusion, the automatic method can be useful to objectively assess the tapping performance of PD patients and can be included in telemedicine tools for remote monitoring of tapping.

    1992-01-01

    Experiments are described which were conducted at the JPL Advanced Teleoperator Lab to demonstrate and evaluate the effectiveness of various teleoperator control modes in the performance of a simulated Solar Max Satellite Repair (SMSR) task. THe SMSR was selected as a test because it is very rich in performance capability requirements and it actually has been performed by two EVA astronauts in the Space Shuttle Bay in 1984. The main subtasks are: thermal blanket removal; installation of a hinge attachment for electrical panel opening; opening of electrical panel; removal of electrical connectors; relining of cable bundles; replacement of electrical panel; securing parts and cables; re-mate electrical connectors; closing of electrical panel; and reinstating thermal blanket. The current performance experiments are limited to thermal blanket cutting, electrical panel unbolting and handling electrical bundles and connectors. In one formal experiment even different control modes were applied to the unbolting and reinsertion of electrical panel screws subtasks. The seven control modes are alternative combinations of manual position and rate control with force feedback and remote compliance referenced to force-torque sensor information. Force-torque sensor and end effector position data and task completion times were recorded for analysis and quantification of operator performance.

  16. An in-house alternative to traditional SDI services at Argonne National Laboratory

    Energy Technology Data Exchange (ETDEWEB)

    Noel, R.E.; Dominiak, R.R.

    1997-02-20

    Selective Dissemination of Information (SDIs) are based on automated, well-defined programs that regularly produce precise, relevant bibliographic information. Librarians have typically turned to information vendors such as Dialog or STN international to design and implement these searches for their users in business, academia, and the science community. Because Argonne National Laboratory (ANL) purchases the Institute for Scientific Information (ISI) Current Contents tapes (all subject areas excluding Humanities). ANL scientists enjoy the benefit of in-house developments with BASISplus software programming and no longer need to turn to outside companies for reliable SDI service. The database and its customized services are known as ACCESS (Argonne Current Contents Electronic Search Service). Through collaboration with librarians on Boolean logic and selection of terms, users can now design their own personal profiles to comb the new data, thereby avoiding service fees from outside providers. Based on the feedback from scientists, it seems that this new service can help transform the ANL distributed libraries into more efficient central functioning entities that better serve the users. One goal is to eliminate the routing of paper copies of many new journal issues to different library locations for users to browse; instead users may be expected to rely more on electronic dissemination of both table of contents and customized SDIs for new scientific and technical information.

  17. Viability of healthcare service delivery alternatives for the Australian mining sector.

    Williams, Patricia A H; Giles, Margaret

    2012-01-01

    The changing and demanding nature of the mining workforce in rural and remote Australia brings unique challenges to the delivery of healthcare services. In an attempt to control costs whilst delivering cost effective and quality healthcare, new models of delivery must be considered. For a workforce that is fly-in/fly-out, the provision of healthcare is problematic given the lack of consistency in location. A cost-benefit framework is analysed comparing three models of service provision using travel to a major location, locum services and remote health monitoring. Ultimately, new models of care must be considered to address the issues of increasing workforce turnover, to cater for rising healthcare costs, and to improve the health of such communities.

    1999-08-01

    As part of studies into the siting of a deep repository for nuclear waste, Swedish Nuclear Fuel and Waste Management Company (SKB) has commissioned the Alternative Models Project (AMP). The AMP is a comparison of three alternative modeling approaches for geosphere performance assessment for a single hypothetical site. The hypothetical site, arbitrarily named Aberg is based on parameters from the Aespoe Hard Rock Laboratory in southern Sweden. The Aberg model domain, boundary conditions and canister locations are defined as a common reference case to facilitate comparisons between approaches. This report presents the results of a discrete fracture pathways analysis of the Aberg site, within the context of the SR 97 performance assessment exercise. The Aberg discrete fracture network (DFN) site model is based on consensus Aberg parameters related to the Aespoe HRL site. Discrete fracture pathways are identified from canister locations in a prototype repository design to the surface of the island or to the sea bottom. The discrete fracture pathways analysis presented in this report is used to provide the following parameters for SKB's performance assessment transport codes FARF31 and COMP23: * F-factor: Flow wetted surface normalized with regards to flow rate (yields an appreciation of the contact area available for diffusion and sorption processes) [TL -1 ]. * Travel Time: Advective transport time from a canister location to the environmental discharge [T]. * Canister Flux: Darcy flux (flow rate per unit area) past a representative canister location [LT -1 ]. In addition to the above, the discrete fracture pathways analysis in this report also provides information about: additional pathway parameters such as pathway length, pathway width, transport aperture, reactive surface area and transmissivity, percentage of canister locations with pathways to the surface discharge, spatial pattern of pathways and pathway discharges, visualization of pathways, and statistical

    1995-12-31

    The State of New York has carried out a comparison of six alternative disposal methods for low-level radioactive waste (LLRW). An important part of these evaluations involved quantitatively analyzing the long-term (10,000 yr) performance of the methods with respect to dose to humans, radionuclide concentrations in the environment, and cumulative release from the facility. Four near-surface methods (covered above-grade vault, uncovered above-grade vault, below-grade vault, augered holes) and two mine methods (vertical shaft mine and drift mine) were evaluated. Each method was analyzed for several generic site conditions applicable for the state. The evaluations were carried out using RIP (Repository Integration Program), an integrated, total system performance assessment computer code which has been applied to radioactive waste disposal facilities both in the U.S. (Yucca Mountain, WIPP) and worldwide. The evaluations indicate that mines in intact low-permeability rock and near-surface facilities with engineered covers generally have a high potential to perform well (within regulatory limits). Uncovered above-grade vaults and mines in highly fractured crystalline rock, however, have a high potential to perform poorly, exceeding regulatory limits.

    Full Text Available Efficiency is generally defined as the extent to which resources or effort is employed in order to achieve a certain purpose or objective. As per an economic perspective, this term may also mean a minimum quantity of supplies which can generate a maximum result. But can we talk about efficiency in terms of human resources and their allocation to a specific task? And how one asses the activity of the employees when considering service encounters? This study aims to provide an answer to these two questions from an emotional labor perspective: individuals employ their emotional abilities in order to perform a certain job. This is a process under a commercial perspective: the wage represents the exchange value for these competencies.

  4. Alternative Shear Panel Configurations for Light Wood Construction. Development, Seismic Performance, and Design Guidance

    2002-04-01

    Shear panels are used in light wood construction to resist lateral loads resulting from earthquakes or strong winds. These panels are typically made of wooden sheathing nailed to building frame members, but this standard panel design interferes with the installation of sheet insulation. A non-insulated shear panel conducts heat between the building interior and exterior wasting considerable amounts of energy. Several alternative shear panel designs were developed to avoid this insulation-mounting problem and sample panels were tested according to standard cyclic test protocols. One of the alternative designs consisted of diagonal steel straps nailed directly to the structural framing. Several others consisted of sheathing nailed to 2 x 4 framing then set into a larger 2 x 6 structural frame in such a way that no sheathing protruded beyond the edge of the 2 x 6 members. Also samples of industry-standard shear panels were constructed and tested in order to establish a performance baseline. Analytical models were developed to size test panels and predict panel behavior. A procedure was developed for establishing design capacities based on both test data and established baseline panel design capacity. The behavior of each panel configuration is documented and recommended design capacities are presented.

    2013-10-01

    Adult participants played computerised games of "Paper Scissors Rock". Participants in one group were told that they were playing against the computer, and those in the other group were told that they were playing against another participant in the adjacent room. The participant who won the most games would receive a $50 prize. For both groups however, the opponent's responses (paper, scissors, or rock) were generated by the computer, and the distribution of these responses was varied across four blocks of 126 trials. Results were analysed using the generalised matching law for the three possible pairs of alternatives (paper vs. scissors, paper vs. rock, and scissors vs. rock) across all participants in each group. Overall, significantly higher estimates of sensitivity to the distribution of opponent's responses were obtained from participants who were told their opponent was a computer compared to participants who were told their opponent was another participant. While adding to the existing literature showing that the generalised matching law is an adequate descriptor of human three-alternative choice behaviour, these findings show that external factors such as perceived opponent type can affect the efficacy of reinforcer contingencies on human behaviour. This suggests that generalising the results from tasks performed against a computer to real-life human-to-human interactions warrants some caution. Copyright © 2013 Elsevier B.V.

    Badami, M.; Nuccio, P.; Pastrone, D.; Signoretto, A.

    2014-01-01

    Highlights: • One synthetic fuel, one bio-fuel blend and one traditional kerosene were tested on a small-scale turbojet. • The three fuels were characterized and their chemical and physical specifications were compared. • The experimental results, in term of CO, UHC and NO x emissions, are discussed. • Emissions are compared with CFD analysis and semi-empirical equations found in literature. - Abstract: The growing use of aeronautical fuels, together with the increasing attention towards reduced environmental impact technologies, are driving governments and aeronautical companies to search for alternative aeronautical fuels to petroleum based kerosene. Analysis and measurements on real aeronautical turbines are complex and expensive; for this reason the use of parts of real engines or small size turbojets can be very interesting for research activities. The present paper describes the results of an experimental and numerical activity, regarding the influence of alternative fuels on the performance in term of emissions, on a small-scale turbojet engine with a nominal thrust of 80 N at 80,000 rpm. Three different fuels, a traditional Jet-A kerosene, a synthetic Gas To Liquid (GTL) fuel and a blend of 30% Jatropha Methyl Ester (JME) and 70% Jet-A, were tested. The experimental results, in term of CO, UHC and NO x emissions, are discussed and compared with results obtained from CFD analysis and from semi-empirical equations found in literature

    2012-01-01

    The ATLAS experiment is being operated by highly distributed computing system which is constantly producing a lot of status information which is used to monitor the experiment operational conditions as well as to access the quality of the physics data being taken. For example the ATLAS High Level Trigger(HLT) algorithms are executed on the online computing farm consisting from about 1500 nodes. Each HLT algorithm is producing few thousands histograms, which have to be integrated over the whole farm and carefully analyzed in order to properly tune the event rejection.

    Bioretention can be an effective measure for stormwater treatment. However, there is a lack of systematic analysis of the impact of bioretention design parameters on hydrologic performance. Herein, SWMM and RECARGA models were applied to generate the typical annual rainfall runoff and simulate the water balance of the bioretention system in an expressway service area. The purpose of the investigation was to identify key design parameters for the bioretention system and delineate the priorities in developing the design. Results showed that the average groundwater recharge ratios for bioretention basins with and without an underdrain were 58.29% and 92.27%, respectively, the average overflow ratios were 4.13% and 4.19%, the average evapotranspiration ratios were 4.48% and 4.47%, and the average outflow ratio for bioretention with an underdrain was 33.94%. The ratio of the bioretention area to drainage area, and the saturated infiltration rates of planting soil and native soil were the main factors influencing water balance, while the underdrain diameter and gravel layer depth exerted little effect. Based on the impact analysis, multivariate nonlinear regression models of runoff reduction rate for two types of bioretention basin were established, which both exhibited high determination coefficients and acceptable Nash-Sutcliffe coefficients.

    Improvements in medication use achieved by pharmacy generalists using a care bundle approach to antimicrobial stewardship are reported. A six-month prospective, repeated-treatment, quasi-experimental study involving three month-long intervention periods and three month-long control periods was conducted in the setting of an existing antimicrobial stewardship program at a large hospital. The intervention involved prospective audit and feedback conducted by pharmacy generalists who were trained in an antimicrobial stewardship care bundle approach. During control months, a pharmacy generalist who was not trained in antimicrobial stewardship rounded with the multidisciplinary team and provided standard-of-care pharmacy services. The primary endpoint was compliance with a care bundle of four antimicrobial stewardship metrics: documentation of indication for therapy in the medical record, selection of empirical therapy according to institutional guidelines, documented performance of indicated culture testing, and deescalation of therapy when indicated. Two-hundred eighty-six patients were enrolled in the study: 124 in the intervention group and 162 in the control group. The cumulative rate of full compliance with all care bundle components during the six-month study was significantly greater during intervention months than during control months (68.5% versus 45.7%, p management.

    2007-01-01

    In this study, two pure hydrocarbon refrigerants, R1270 (propylene) and R290 (propane), and three binary mixtures composed of R1270, R290 and R152a were tested in a refrigerating bench tester with a scroll compressor in an attempt to substitute R502, which is used in most low temperature and transport refrigeration applications. The test bench provided 3-3.5 kW capacity, and water and water/glycol mixture were employed as the secondary heat transfer fluids. All tests were conducted under the same external conditions, resulting in the average saturation temperatures of -28 and 45 o C in the evaporator and condenser, respectively. The test results showed that all refrigerants tested had 9.6-18.7% higher capacity and 17.1-27.3% higher COP than R502. The compressor discharge temperature of R1270 was similar to that of R502, while those of all the other refrigerants were 23.7-27.9 o C lower than that of R502. For all alternative refrigerants, the charge was reduced up to 60% as compared to R502. There, of course, was no problem with mineral oil, since the mixtures were mainly composed of hydrocarbons. Since some of them are mixtures, one can change their compositions a little to suit various needs in many applications without significant deterioration of the performance. Overall, these alternative refrigerants offer better system performance and reliability than R502 and can be used as long term substitutes for R502 due to their excellent environmental properties

    The global demand for polystyrene is supposed to reach an overall baseline of 23.5 million tons by 2020. The market has experienced the effects of such growth, especially regarding the environmental performance of the production processes. In Brazil, renewable assets have been used to overcome the adverse consequences of this expansion. This study evaluates this issue for the production of Brazilian polystyrene resins, general-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS). The effects of replacing fossil ethylene with a biobased alternative are also investigated. Life Cycle Assessment is applied for ten scenarios, with different technological approaches for renewable ethylene production and an alternative for obtaining bioethanol, which considers the export of electricity. The fossil GPPS and HIPS show a better performance than the partially renewable sources in terms of Climate Change (CC), Terrestrial Acidification (TA), Photochemical Oxidant Formation (POF), and Water Depletion (WD). The exception is Fossil Depletion (FD), a somewhat predictable result. The main environmental loads associated with the renewable options are related to the sugarcane production. Polybutadiene fails to provide greater additional impact to HIPS when compared to GPPS. With regard to obtaining ethylene from ethanol, Adiabatic Dehydration (AD) technology consumes less sugarcane than Adiabatic Dehydration at High Pressure (ADHP), which leads to gains in TA and POF. In contrast, ADHP was more eco-friendly for WD because of its lower water losses and in terms of CC because of the advantageous balance of fossil CO2(eq) at the agricultural stage and the lower consumption of natural gas in ethylene production. The electricity export is an auspicious environmental opportunity because it can counterbalance some of the negative impacts associated with the renewable route. According to a "cradle-to-grave" perspective, the partially renewable resins show a more favorable balance of

  15. Environmental acceptability of high-performance alternatives for depleted uranium penetrators

    1996-08-01

    The Army`s environmental strategy for investigating material substitution and management is to measure system environmental gains/losses in all phases of the material management life cycle from cradle to grave. This study is the first in a series of new investigations, applying material life cycle concepts, to evaluate whether there are environmental benefits from increasing the use of tungsten as an alternative to depleted uranium (DU) in Kinetic Energy Penetrators (KEPs). Current military armor penetrators use DU and tungsten as base materials. Although DU alloys have provided the highest performance of any high-density alloy deployed against enemy heavy armor, its low-level radioactivity poses a number of environmental risks. These risks include exposures to the military and civilian population from inhalation, ingestion, and injection of particles. Depleted uranium is well known to be chemically toxic (kidney toxicity), and workplace exposure levels are based on its renal toxicity. Waste materials containing DU fragments are classified as low-level radioactive waste and are regulated by the Nuclear Regulatory Commission. These characteristics of DU do not preclude its use in KEPs. However, long-term management challenges associated with KEP deployment and improved public perceptions about environmental risks from military activities might be well served by a serious effort to identify, develop, and substitute alternative materials that meet performance objectives and involve fewer environmental risks. Tungsten, a leading candidate base material for KEPS, is potentially such a material because it is not radioactive. Tungsten is less well studied, however, with respect to health impacts and other environmental risks. The present study is designed to contribute to the understanding of the environmental behavior of tungsten by synthesizing available information that is relevant to its potential use as a penetrator.

    1993-01-01

    In the Health and Safety Executive's ''Requirements for the Approval of Dosimetry Services under the Ionising Radiations Regulations 1985'', it is stipulated that dosimetry services seeking approval must show that they have successfully completed a performance test. The services must arrange for the tests to be carried out on application and thereafter every 18 months, by a laboratory which has received accreditation from the National Measurement Accreditation Service (NAMAS) for the whole performance testing activity. The performance tests must be carried out to published protocols and the purpose here is to provide protocols for external, whole body film and TLD dosimetry services, and for skin and extremity dosimetry services.

  18. The performance of low-cost commercial cloud computing as an alternative in computational chemistry.

    Science.gov (United States)

    Thackston, Russell; Fortenberry, Ryan C

    2015-05-05

    The growth of commercial cloud computing (CCC) as a viable means of computational infrastructure is largely unexplored for the purposes of quantum chemistry. In this work, the PSI4 suite of computational chemistry programs is installed on five different types of Amazon World Services CCC platforms. The performance for a set of electronically excited state single-point energies is compared between these CCC platforms and typical, "in-house" physical machines. Further considerations are made for the number of cores or virtual CPUs (vCPUs, for the CCC platforms), but no considerations are made for full parallelization of the program (even though parallelization of the BLAS library is implemented), complete high-performance computing cluster utilization, or steal time. Even with this most pessimistic view of the computations, CCC resources are shown to be more cost effective for significant numbers of typical quantum chemistry computations. Large numbers of large computations are still best utilized by more traditional means, but smaller-scale research may be more effectively undertaken through CCC services. © 2015 Wiley Periodicals, Inc.

    We analyzed the extent to which the service recovery performance of frontline employees in private health care institutions is influenced by employee perceptions of manager attitudes toward service quality, workplace support, and manager fairness and organizational commitment. We also examined the relationship of service recovery performance to employee job satisfaction and turnover intentions. Partial least square path modeling of data from 178 frontline employees in private health care institutions in North Cyprus was utilized. Although empowerment and role clarity were positively related to service recovery performance, perceived managerial attitudes toward hospital customer service, teamwork, and customer service-oriented training as indicators of workplace support were not related to frontline employees' service recovery performance. Organizational justice was related to affective commitment, which in turn was related to service recovery performance. Although service recovery performance was not related to employee turnover intentions, it was related to job satisfaction. Managerial implications of these study findings are presented in the light of the cognitive evaluation theory. Health services differ from other service organizations in the way that intrinsic and extrinsic rewards influence the service recovery efforts of frontline employees. To ensure high quality services, managers should focus on intrinsic rewards, empower and give more autonomy to staff.

    2015-11-01

    Role of alternative fuels on reducing the combustion pollutants is gaining momentum in both land and air transport. Recent studies have shown that addition of nanoscale metal particles as fuel additives to liquid fuels have a positive effect not only on their combustion performance but also in reducing the pollutant formation. However, most of those studies are still in the early stages of investigation with the addition of nanoparticles at low weight percentages. Such an addition can affect the hydrodynamic and thermo-physical properties of the fuel. In this study, the near nozzle spray performance of gas-to-liquid jet fuel with and without the addition of alumina nanoparticles are investigated at macro- and microscopic levels using optical diagnostic techniques. At macroscopic level, the addition of nanoparticles is seen to enhance the sheet breakup process when compared to that of the base fuel. Furthermore, the microscopic spray characteristics such as droplet size and velocity are also found to be affected. Although the addition of nanoscale metal particles at low weight percentages does not affect the bulk fluid properties, the atomization process is found to be affected in the near nozzle region.

  6. Alternative oxidase: a respiratory electron transport chain pathway essential for maintaining photosynthetic performance during drought stress.

    2016-07-01

    Photosynthesis and respiration are the hubs of energy metabolism in plants. Drought strongly perturbs photosynthesis as a result of both diffusive limitations resulting from stomatal closure, and in some cases biochemical limitations that are associated with a reduced abundance of key photosynthetic components. The effects of drought on respiration, particularly respiration in the light (RL ), are less understood. The plant mitochondrial electron transport chain includes a non-energy conserving terminal oxidase called alternative oxidase (AOX). Several studies have shown that drought increases AOX transcript, protein and maximum capacity. Here we review recent studies comparing wild-type (WT) tobacco to transgenic lines with altered AOX protein amount. Specifically during drought, RL was compromised in AOX knockdown plants and enhanced in AOX overexpression plants, compared with WT. Significantly, these differences in RL were accompanied by dramatic differences in photosynthetic performance. Knockdown of AOX increased the susceptibility of photosynthesis to drought-induced biochemical limitations, while overexpression of AOX delayed the development of such biochemical limitations, compared with WT. Overall, the results indicate that AOX is essential to maintaining RL during drought, and that this non-energy conserving respiration maintains photosynthesis during drought by promoting energy balance in the chloroplast. This review also outlines several areas for future research, including the possibility that enhancement of non-energy conserving respiratory electron sinks may be a useful biotechnological approach to increase plant performance during stress. © 2016 Scandinavian Plant Physiology Society.

    To evaluate the cost-effectiveness of changing opening times, introducing a donor health report and reducing the minimum inter-donation interval for donors attending static centres. Evidence is required about the effect of changes to the blood collection service on costs and the frequency of donation. This study estimated the effect of changes to the blood collection service in England on the annual number of whole-blood donations by current donors. We used donors' responses to a stated preference survey, donor registry data on donation frequency and deferral rates from the INTERVAL trial. Costs measured were those anticipated to differ between strategies. We reported the cost per additional unit of blood collected for each strategy versus current practice. Strategies with a cost per additional unit of whole blood less than £30 (an estimate of the current cost of collection) were judged likely to be cost-effective. In static donor centres, extending opening times to evenings and weekends provided an additional unit of whole blood at a cost of £23 and £29, respectively. Introducing a health report cost £130 per additional unit of blood collected. Although the strategy of reducing the minimum inter-donation interval had the lowest cost per additional unit of blood collected (£10), this increased the rate of deferrals due to low haemoglobin (Hb). The introduction of a donor health report is unlikely to provide a sufficient increase in donation frequency to justify the additional costs. A more cost-effective change is to extend opening hours for blood collection at static centres. © 2018 The Authors.

    Optimal scheduling and calendar management in an outpatient chemotherapy unit is a complex process that is driven by a need to focus on safety while accommodating a high degree of variability. Primary constraints are infusion times, staffing resources, chair availability, and unit hours. We undertook a process to analyze our existing management models across multiple practice settings in our health care system, then developed a model to optimize safety and efficiency. The model was tested in one of the community chemotherapy units. We assessed staffing violations as measured by nurse-to-patient ratios throughout the workday and at key points during treatment. Staffing violations were tracked before and after the implementation of the new model. The new model reduced staffing violations by nearly 50% and required fewer chairs to treat the same number of patients for the selected clinic day. Actual implementation results indicated that the new model leveled the distribution of patients across the workday with an 18% reduction in maximum chair utilization and a 27% reduction in staffing violations. Subsequently, a positive impact on peak pharmacy workload reduced delays by as much as 35 minutes. Nursing staff satisfaction with the new model was positive. We conclude that the proposed optimization approach with regard to nursing resource assignment and workload balance throughout a day effectively improves patient service quality and staff satisfaction.

  14. Trade-offs between ecosystem services and alternative pathways toward sustainability in a tropical dry forest region

    Directory of Open Access Journals (Sweden)

    Francisco Mora

    2016-12-01

    Full Text Available The design of strategies aimed at sustainable resource management requires an understanding of the trade-offs between the ecosystem services at stake, to determine appropriate ways in which to navigate them. We assess trade-offs between forage production for cattle ranching and the maintenance of carbon stocks or tree diversity in a Mexican tropical dry forest. Trade-offs between pairs of services were assessed by identifying their efficiency frontiers at both site and landscape scales. We also estimated service outcomes under current and hypothetical land-management conditions. We found stark trade-offs between fodder and carbon stocks and between fodder and tree species richness at the site scale. At the landscape scale, the efficiency frontier was concave, with a much less pronounced trade-off in the fodder-species richness case. Our estimates of current service supply levels showed a reduction of 18-21% for C stock and 41-43% for fodder biomass, relative to the maximum feasible values along the efficiency frontier. Choice of the optimum management strategy to reduce such inefficiency depended on deforestation level: secondary forest regeneration was most suitable when deforestation is low, whereas increased fodder productivity in the pastures is best when deforestation is high. Pasture enrichment with forage trees and secondary forest growth are potential management alternatives for achieving sustainability given the range of enabling ecological factors and to balance ecological and social sustainability given the requirements and preferences of local stakeholders. Given that analogous trade-offs are found across the tropics, this work contributes to reconciling tropical forest maintenance and its use for sustainable rural livelihoods.

    The industrial needs in reducing the energy consumption is part of a continuing search towards higher levels of sustainability and competitiveness. Considering these aspects, the aluminum industry seeks new alternatives for a better performance of aluminum melting and holding furnaces and this aim is directly dependent on the refractory materials ability to conserve heat and withstand the mechanical, chemical and thermal degradation processes. This paper presents the thermo-mechanical characterization of five aluminous dense commercial refractory (average density of 2.7 g / cm ³), used in such equipment. The results indicated that choosing the most suitable composition requires the evaluation of the microstructure aspects, such as porosity, permeability and pore size, and also the refractory's physical integrity, such as thermal shock resistance, abrasion resistance and high temperature modulus of rupture. The laboratory tests allowed the characterization of all the materials at the same conditions. Moreover, it was possible to optimize the selection of lining materials for melting and holding furnaces and to provide basis to a possible costs improvements synergy. (author)

    A field study was conducted to assess the ability of landfill covers to control percolation into the waste. Performance of one conventional cover was compared to that of two evapotranspiration (ET) tree covers, using large (7 x 14 m) lined lysimeters at the Leon County Solid Waste management facility in Tallahassee, Florida. Additional unlined test sections were also constructed and monitored in order to compare soil water storage, soil temperature, and tree growth inside lysimeters and in unlined test sections. The unlined test sections were in direct contact with landfill gas. Surface runoff on the ET covers was a small proportion of the water balance (1% of precipitation) as compared to 13% in the conventional cover. Percolation in the ET covers averaged 17% and 24% of precipitation as compared to 33% in the conventional cover. On average, soil water storage was higher in the lined lysimeters (429 mm) compared to unlined test sections (408 mm). The average soil temperature in the lysimeters was lower than in the unlined test sections. The average tree height inside the lysimeters was not significantly lower (8.04 mfor eucalyptus and 7.11 mfor cottonwood) than outside (8.82 m for eucalyptus and 8.01 m for cottonwood). ET tree covers vegetated with cottonwood or eucalyptus are feasible for North Florida climate as an alternative to GCL covers.

  17. Study of Gasohol as Alternative Fuel for Gasoline Substitution: Characteristics and Performances

    Directory of Open Access Journals (Sweden)

    Bardi Murachman

    2014-12-01

    Full Text Available Gasohol is a mixture of premium petrol (gasoline with alcohol, in this case ethanol. The use of gasohol can reduce fuel consumption without having to modify the existing engine. Therefore, this research is conducted to study the characteristics and performance of gasohol in various mixing ratios, which includes analysis of physical properties and the use of gasohol in the machine. Results show that the addition of technical ethanol at 7.0169%v increases the value of gasohol vapor pressure on the value of 8.6682 psi (7.7 psi for regular gasoline. Gasohol with technical ethanol content above 30%v decreases vapor pressure, promotes phase separation, and causes a sharp drop in temperature from 40%v distillation. In term of corrosivity, gasohol with up to 50%v ethanol content has the same corrosion level with regular gasoline, which is corrosion level 1A. Based on gasohol characteristics test, it is known that gasohol with technical ethanol content below 20%v can be used as a fuel substitute for gasoline. Real-time performance test of gasohol in engines has shown that the addition of ethanol content in gasohol tend to increase the engine power at a certain compression ratio, but it also increases fuel consumption because the heat value of ethanol is lower than gasoline. Machine in gasohol with ethanol content below 20%v can operate smoothly without having to modify the engine. Based on the studies that have been done, gasohol in the range of 10%v ethanol content is well-functioned as a substitute for gasoline fuel and meets fuel specifications required by the General Director of Oil and Gas. The feasibility of using gasohol as an alternative fuel can be studied further.

  20. Assessment of Energy Performance and Emission Control Using Alternative Fuels in Cement Industry through a Process Model

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Cement manufacturing is one of the most energy intensive processes and is accountable for substantial pollutant emissions. Increasing energy costs compel stakeholders and researchers to search for alternative options to improve energy performance and reduce CO2 emissions. Alternative fuels offer a realistic solution towards the reduction of the usage of fossil fuels and the mitigation of pollutant emissions. This paper developed a process model of a precalciner kiln system in the cement industry using Aspen Plus software to simulate the effect of five alternative fuels on pollutant emissions and energy performance. The alternatives fuels used were tyre, municipal solid waste (MSW, meat and bone meal (MBM, plastic waste and sugarcane bagasse. The model was developed on the basis of energy and mass balance of the system and was validated against data from a reference cement plant. This study also investigated the effect of these alternative fuels on the quality of the clinker. The results indicated that up to a 4.4% reduction in CO2 emissions and up to a 6.4% reduction in thermal energy requirement could be achieved using these alternative fuels with 20% mix in coal. It was also found that the alternative fuels had minimum influence on the clinker quality except in the case of MSW. Overall, MBM was found to be a better option as it is capable on reducing energy requirement and CO2 emissions more than others. The outcomes of the study offer better understanding of the effects of solid alternative fuels to achieve higher energy performance and on mitigating pollutant emissions in cement industry.

  6. Performance Comparison of Reservation Based and Instant Access One-Way Car Sharing Service through Discrete Event Simulation

    Directory of Open Access Journals (Sweden)

    Ganjar Alfian

    2015-09-01

    Full Text Available A car sharing service has been highlighted as a new urban transport alternative for an environmentally friendly economy. As the demand for the service from customers increases, car sharing operators need to introduce a new service such as a one-way option that will allow customers to return the car to different stations. Due to the complexity of the one-way system, it needs to be managed and optimized for real cases. This paper focuses on developing a simulation model in order to help operators evaluate the performance of the one-way service. In addition, this research demonstrates a strategy for an open one-way service that can increase revenue and customer satisfaction. A real case dataset is used for investigation to find the best result from the simulation. The result showed that the total number of cars, number of one-way reservations and station size have an impact on one-way performance. Thus, company profit and customer satisfaction can be maximized by optimizing these factors.

  7. Northeast Empire Limited Partnership No. 2 Alternative Energy, Inc. and Maine Public Service Company (Docket No. EA-95): Environmental Assessment

    International Nuclear Information System (INIS)

    1992-05-01

    This environmental assessment (EA) has been prepared in connection with the application (the Application) by Alternative Energy, Inc. (AEI), Northeast Empire Limited Partnership number-sign 2 (the Partnership) and Maine Public Service Company (MPS and, collectively with AEI and the Partnership, the Applicants), filed on January 6, 1992, for authorization to transmit electric energy to a foreign country. The electric energy to be exported would be produced by a 39-megawatt (MW), wood-fired powerplant (the Project) to be developed by AEI and to be built by the Partnership in Ashland, Maine, which is located in MPS' service territory. In the Application, the Applicants requested authorization for MPS to transmit electricity generated by the Project from Maine through New Brunswick, Canada, on route back to the US for domestic use by Central Maine Power Company (MP). The need to cross the US -Canadian border arises due to the geography of the area and to facilitate access to an existing transmission line. None of the power will be used in Canada. This EA addresses the environmental impacts associated with the export of electric energy and the connected actions which are expected to result from the authorization of those exports. The electricity would be exported over cross-border transmission facilities maintained between MPS and New Brunswick Power Corporation (NB Power). No new cross-border facilities, and no modification of any existing cross-border facilities, are required in connection with the proposed action

    Blaakman, Aaron Philip; Salehi, Ahmad Shah; Boitard, Romain

    2014-01-01

    Since 2003, the Afghan Ministry of Public Health (MoPH) and international partners have directed a contracting-out model through which non-governmental organisations (NGOs) deliver the Basic Package of Health Services (BPHS) in 31 of the 34 Afghan provinces. The MoPH also managed health service delivery in three provinces under an alternative initiative entitled Strengthening Mechanisms (SM). In 2011, under the authority of the MoPH and Delegation of the European Union to Afghanistan, EPOS Health Management conducted a cost and technical efficiency study of the contracting-out and SM mechanisms in six provinces to examine economic trade-offs in the provision of the BPHS. The study provides analyses of all resource inputs and primary outputs of the BPHS in the six provinces during 2008 and 2009. The authors examined technical efficiency using Data Envelopment Analysis (DEA) at the BPHS facility level. Cost analysis results indicate that the weighted average cost per BPHS outpatient visit totalled $3.41 in the SM provinces and $5.39 in the NGO-led provinces in 2009. Furthermore, the data envelopment analyses (DEAs) indicate that facilities in the three NGO-led provinces scored 0.168 points higher on the DEA scale (0-1) than SM facilities. The authors conclude that an approximate 60% increase in costs yielded a 16.8% increase in technical efficiency in the delivery of the BPHS during 2009 in the six provinces.

    1995-01-01

    The most appropriate conceptual model for performance assessment (PA) at the waste isolation pilot plant (WIPP) is believed to include gas generation resulting from corrosion and microbial action in the repository, and a dual-porosity (matrix and fracture porosity) representation for the solute transport in the Culebra dolomite member of the Rustler formation. Under these assumptions, complementary cummulative distribution functions (CCDFs) which summarize the radionuclide releases to the accessible environment, resulting from both cutting removal and groundwater transport, fall substantially below the release limits promulgated by the US Environmental Protection Agency (EPA), with the releases being dominated by cuttings removal. To provide additional views, the following alternative conceptual models were considered as part of a preliminary PA for the WIPP: no gas generation in the repository and a dual-porosity transport model in the Culebra; gas generation in the repository and a single-porosity (fracture porosity) transport model in the Culebra; no gas generation in the repository and a single-porosity transport model in the Culebra; gas generation in the repository and a dual-porosity transport model in the Culebra, without chemical retardation; gas generation in the repository, chemical retardation in the Culebra, and extremes of climatic variation. These variations relate to groundwater transport, so do not affect the releases resulting from cuttings removal. Several of these variations substantially increase the importance of releases resulting from groundwater transport relative to releases resulting from cuttings removal. However, the total amount of releases generally remained small, with the CCDFs which summarize the releases to the accessible environment falling below the EPA release limits

    2016-03-01

    Adopting high performance cloud computing for medical image processing is a popular trend given the pressing needs of large studies. Amazon Web Services (AWS) provide reliable, on-demand, and inexpensive cloud computing services. Our research objective is to implement an affordable, scalable and easy-to-use AWS framework for the Java Image Science Toolkit (JIST). JIST is a plugin for Medical- Image Processing, Analysis, and Visualization (MIPAV) that provides a graphical pipeline implementation allowing users to quickly test and develop pipelines. JIST is DRMAA-compliant allowing it to run on portable batch system grids. However, as new processing methods are implemented and developed, memory may often be a bottleneck for not only lab computers, but also possibly some local grids. Integrating JIST with the AWS cloud alleviates these possible restrictions and does not require users to have deep knowledge of programming in Java. Workflow definition/management and cloud configurations are two key challenges in this research. Using a simple unified control panel, users have the ability to set the numbers of nodes and select from a variety of pre-configured AWS EC2 nodes with different numbers of processors and memory storage. Intuitively, we configured Amazon S3 storage to be mounted by pay-for- use Amazon EC2 instances. Hence, S3 storage is recognized as a shared cloud resource. The Amazon EC2 instances provide pre-installs of all necessary packages to run JIST. This work presents an implementation that facilitates the integration of JIST with AWS. We describe the theoretical cost/benefit formulae to decide between local serial execution versus cloud computing and apply this analysis to an empirical diffusion tensor imaging pipeline.

  17. Development and performance measurement of micro-power pack using micro-gas turbine driven automotive alternators

    International Nuclear Information System (INIS)

    Sim, Kyuho; Koo, Bonjin; Kim, Chang Ho; Kim, Tae Ho

    2013-01-01

    Highlights: ► We develop micro-power pack using automotive alternator and micro-gas turbine. ► We measure rotordynamic and power generation performance of micro-power pack. ► Micro-power pack shows dramatic increases in mass and volumetric power densities. ► Test results assure feasibility of micro-power pack for electric vehicles. -- Abstract: This paper presents the development of a micro-power pack using automotive alternators powered by a micro-gas turbine (MGT) to recharge battery packs, in particular for electric vehicles (EVs). The thermodynamic efficiency for the MGT with the power turbine is estimated from a simple Brayton cycle analysis. The rotordynamic and power generation performance of the MGT driven alternator was measured during a series of experiments under electrical no-loading and loading conditions, and with belt-pulley and flexible bellows couplings. The flexible coupling showed superior rotordynamic and power generation performance than the belt coupling due to the enhanced alignment of the alternator rotor and the reduced mechanical frictions. Furthermore, the micro-power pack showed dramatic increases in the mass and volumetric power densities by ∼4 times and ∼5 times, respectively, compared with those of a commercial diesel generator with similar power level. As a result, this paper assures the feasibility of the light-weight micro-power pack using a MGT and automotive alternators for EVs.

  19. Performing Ecosystem Services at Mud Flats in Seocheon, Korea: Using Q Methodology for Cooperative Decision Making

    Directory of Open Access Journals (Sweden)

    Jae-Hyuck Lee

    2017-05-01

    Full Text Available The concept of ecosystem services, which are the direct and indirect benefits of nature to humans, has been established as a supporting tool to increase the efficiency in decision-making regarding environmental planning. However, preceding studies on decision-making in relation to ecosystem services have been limited to identifying differences in perception, whereas few studies have reported cooperative alternatives. Therefore, this study aimed to present a method for cooperative decision-making among ecosystem service stakeholders using Q methodology. The results showed three perspectives on ecosystem services of small mud flat areas: ecological function, ecotourism, and human activity. The perspectives on cultural services and regulating services were diverse, whereas those on supporting services were similar. Thus, supporting services were considered crucial for the cooperative assessment and management of small mud flat ecosystems as well as for the scientific evaluation of regulating services. Furthermore, this study identified practical implementation measures to increase production through land management, to manufacture related souvenirs, and to link them to ecotourism. Overall, our results demonstrated the ideal process of cooperative decision-making to improve ecosystem services.

Idea: The core idea of the paper is to measure the effects of logistics process on customer service and the performance of furniture manufacturing firms. The study takes the logistics process as an independent variable, the customer service as the first dependent variable and manufacturing performance as a moderating variable. Data: Primary data on logistics, customer service, manufacturing flexibility and firm performance were conveniently collected through a questionnaire from owners/managers of 61 furniture manufacturing firms. Tool: Descriptive statistics, correlation and regression analyses were run to draw the results. Findings: Logistics processes positively affect customer service and firm performance. Customer service also exerts a positive effect on firm performance while the moderating role of manufacturing flexibility was not supported for the relationship of logistics processes and customer service. Contribution: Through efficiency in logistics processes, furniture manufacturing firms can serve customers in a superior way to ultimately achieve improved firm performance. The framework being restricted to efficiency of logistics processes only constitutes an important limitation of the study.

    An experimental campaign on plate heat exchangers, used as evaporators and condenser in domestic refrigeration loops is presented in this paper. The research's purpose is to test the influence of some thermal-hydraulic parameters on the global overall heat transfer coefficient. R134a, R407C, R410A, and R22 are the fluids tested under reference thermal conditions. The experimental tests allows one to withdraw conclusions on the substitution effect on the thermal and global efficiency of the plant. Also, a new method for calculating the thermodynamical mixture parameters is applied to the condensation of mixtures R407C and R410A and its benefit evaluated. The refrigerant loop overall performance and the condenser global heat transfer coefficient are the parameters chosen to enlighten the characteristics of the alternative refrigerants (R134a, R407C, and R410A) with respect to the fluid that they are supposed to substitute (R22). [Italian] Scambiatori a piastre compatti impiegati come evaporatori e condensatori nei circuiti frigoriferi, sono l'oggetto della ricerca presentata in questo articolo. L'efficienza termica di tali componenti e' valutata in condizioni di riferimento commerciali. I refrigeranti utilizzati sono tre fluidi proposti per sostituire l'R22, un Hcfc, attualmente il refrigerante piu' utilizzato nel condizionamento ambientale. Una serie di prove condotte con quest'ultimo fluido consente di studiare gli effetti della sostituzione del fluido di progetto sulle prestazioni sia degli scambiatori, sia piu' in generale, dell'intero circuito frigorifero. In particolare sono state studiate le prestazioni di due coppie di evaporatori e condensatori in termini di coefficiente globale di scambio termico e di Cop dell'impianto.

    GNSS is being used effectively to precise position for many measuring and geodetic purposes at the present time. There is an increasing variety of these systems including the post-processing calculations in terms of number, quality and features and many different techniques are developed to determine position. Precise positioning intend to derive requires user experience and scientific or commercial software with costly license fees. However, in recent years important alternatives to this software that are user friendly and offer free web-based online precise point positioning service have become widely used in geodetic applications. The aim of this study is to test the performance of PPP techniques on ground control points with different visibility conditions. Within this framework, static observations were carried out for three hours a day repeatedly for six days, in YTU Davutpasa Campus on three different ground control points. The locations of these stations were selected by taking into account the impact of natural (trees, etc.) and artificial (buildings, etc.) obstacles. In order to compare the obtained GPS observations with PPP performances, first of all the accurate coordinates of the control points were computed with relative positioning technique in connection with the IGS stations using Bernese v5.0 software. Afterwards, three different web-based positioning services (CSRS-PPP, magicGNSS, GAPS) were used to analyze the GPS observations via PPP technique. To compare all of the obtained results, ITRF2008 datum measurement epoch coordinates were preferred by taking the service result criteria into consideration. In coordinate comparison, for the first station located nearby a building and possibly subjected to multipath effect horizontal discrepancies vary between 2-14.5 cm while vertical differences are between 3.5-16 cm. For the second point located partly in a forestry area, the discrepancies have been obtained as 1.5-8 cm and 2-10 cm for horizontal and

    2014-11-01

    To explore whether oral impacts on daily performances are related to recent use of dental services among children and whether oral impacts on specific daily performances are more strongly related to recent use of dental services. Data from a cross-sectional survey, including 805 11-12-year-old children attending four randomly selected schools in Lima (Peru), were used. The child version of the oral impacts on daily performances (Child-OIDP) was used to assess prevalence, intensity, and extent of oral impacts. Use of dental services was assessed by self-reports of last dental visit and reason for the visit. Associations of the prevalence, intensity, and extent of oral impacts with use of dental services were tested in logistic regression models. Children with oral impacts were 1.99 (95% CI: 1.17-3.37) times more likely to have used dental services recently than their counterparts. The intensity and extent of oral impacts were linearly associated with children's use of dental services. Difficulties in eating were the only type of oral impacts on daily performances associated with use of dental services, independent of children's demographic characteristics, and impacts on other performances. Oral impacts on daily performances were related to recent use of dental services among these schoolchildren. © 2013 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    An integral part of a system that manages medical data is the persistent storage engine. For almost twenty five years Relational Database Management Systems(RDBMS) were considered the obvious decision, yet today new technologies have emerged that require our attention as possible alternatives. Triplestores store information in terms of RDF triples without necessarily binding to a specific predefined structural model. In this paper we present an attempt to compare the performance of Apache JENA-Fuseki and the Virtuoso Universal Server 6 triplestores with that of MySQL 5.6 RDBMS for storing and retrieving medical information that it is communicated as RDF/XML ontology instances over a RESTful web service. The results show that the performance, calculated as average time of storing and retrieving instances, is significantly better using Virtuoso Server while MySQL performed better than Fuseki.

    Full Text Available AYUSH, an acronym for Ayurveda, Yoga and Naturopathy, Unani, Siddha, Sowa-Rigpa and Homeopathy represents the alternative systems of medicine recognized by the Government of India. Understanding the patterns of utilization of AYUSH care has been important for various reasons including an increased focus on its mainstreaming and integration with biomedicine-based health care system. Based on a nationally representative health survey 2014, we present an analysis to understand utilization of AYUSH care across socioeconomic and demographic groups in India. Overall, 6.9% of all patients seeking outpatient care in the reference period of last two weeks have used AYUSH services without any significant differentials across rural and urban India. Importantly, public health facilities play a key role in provisioning of AYUSH care in rural areas with higher utilization in Chhattisgarh, Kerala and West Bengal. Use of AYUSH among middle-income households is lower when compared with poorer and richer households. We also find that low-income households display a greater tendency for AYUSH self-medication. AYUSH care utilization is higher among patients with chronic diseases and also for treating skin-related and musculo-skeletal ailments. Although the overall share of AYUSH prescription drugs in total medical expenditure is only about 6% but the average expenditure for drugs on AYUSH and allopathy did not differ hugely. The discussion compares our estimates and findings with other studies and also highlights major policy issues around mainstreaming of AYUSH care.

  7. The paradox of non-evidence based, publicly funded complementary alternative medicine in the English National Health Service: An explanation.

    Science.gov (United States)

    Sheppard, Maria K

    2015-10-01

    Despite the unproven effectiveness of many practices that are under the umbrella term 'complementary alternative medicine' (CAM), there is provision of CAM within the English National Health Service (NHS). Moreover, although the National Institute for Health and Care Excellence was established to promote scientifically validated medicine in the NHS, the paradox of publicly funded, non-evidence based CAM can be explained as linked with government policy of patient choice and specifically patient treatment choice. Patient choice is useful in the political and policy discourse as it is open to different interpretations and can be justified by policy-makers who rely on the traditional NHS values of equity and universality. Treatment choice finds expression in the policy of personalised healthcare linked with patient responsibilisation which finds resonance in the emphasis CAM places on self-care and self-management. More importantly, however, policy-makers also use patient choice and treatment choice as a policy initiative with the objective of encouraging destabilisation of the entrenched healthcare institutions and practices considered resistant to change. This political strategy of system reform has the unintended, paradoxical consequence of allowing for the emergence of non-evidence based, publicly funded CAM in the NHS. The political and policy discourse of patient choice thus trumps evidence based medicine, with patients that demand access to CAM becoming the unwitting beneficiaries.

  8. Cross-Sectoral Resource Management: How Forest Management Alternatives Affect the Provision of Biomass and Other Ecosystem Services

    Directory of Open Access Journals (Sweden)

    Susanne Frank

    2015-02-01

    Full Text Available Integrated forest management is faced with the challenge that the contribution of forests to economic and ecological planning targets must be assessed in a socio-ecological system context. This paper introduces a way to model spatio-temporal dynamics of biomass production at a regional scale in order to derive land use strategies that enhance biomass provision and avoid trade-offs for other ecosystem services. The software platform GISCAME was employed to bridge the gap between local land management decisions and regional planning by linking growth and yield models with an integrative mesoscale modeling and assessment approach. The model region is located in Saxony, Germany. Five scenarios were simulated, which aimed at testing different alternatives for adapted land use in the context of climate change and increasing biomass demand. The results showed, for example, that forest conversion towards climate-change-adapted forest types had positive effects on ecological integrity and landscape aesthetics. In contrast, negative impacts on landscape aesthetics must be expected if agricultural sites were converted into short rotation coppices. Uncertainties with stem from assumptions regarding growth and yield models were discussed. Future developmental steps which consider, for example, accessibility of the resources were identified.

  10. Performance Prediction of Centrifugal Compressor for Drop-In Testing Using Low Global Warming Potential Alternative Refrigerants and Performance Test Codes

    Directory of Open Access Journals (Sweden)

    Joo Hoon Park

    2017-12-01

    Full Text Available As environmental regulations to stall global warming are strengthened around the world, studies using newly developed low global warming potential (GWP alternative refrigerants are increasing. In this study, substitute refrigerants, R-1234ze (E and R-1233zd (E, were used in the centrifugal compressor of an R-134a 2-stage centrifugal chiller with a fixed rotational speed. Performance predictions and thermodynamic analyses of the centrifugal compressor for drop-in testing were performed. A performance prediction method based on the existing ASME PTC-10 performance test code was proposed. The proposed method yielded the expected operating area and operating point of the centrifugal compressor with alternative refrigerants. The thermodynamic performance of the first and second stages of the centrifugal compressor was calculated as the polytropic state. To verify the suitability of the proposed method, the drop-in test results of the two alternative refrigerants were compared. The predicted operating range based on the permissible deviation of ASME PTC-10 confirmed that the temperature difference was very small at the same efficiency. Because the drop-in test of R-1234ze (E was performed within the expected operating range, the centrifugal compressor using R-1234ze (E is considered well predicted. However, the predictions of the operating point and operating range of R-1233zd (E were lower than those of the drop-in test. The proposed performance prediction method will assist in understanding thermodynamic performance at the expected operating point and operating area of a centrifugal compressor using alternative gases based on limited design and structure information.

    Full Text Available With rapid advancement of Cloud computing and networking technologies, a wide spectrum of Cloud services have been developed by various providers and utilized by numerous organizations as indispensable ingredients of their information systems. Cloud service performance has a significant impact on performance of the future information infrastructure. Thorough evaluation on Cloud service performance is crucial and beneficial to both service providers and consumers; thus forming an active research area. Some key technologies for Cloud computing, such as virtualization and the Service-Oriented Architecture (SOA, bring in special challenges to service performance evaluation. A tremendous amount of effort has been put by the research community to address these challenges and exciting progress has been made. Among the work on Cloud performance analysis, evaluation approaches developed with a system modeling perspective play an important role. However, related works have been reported in different sections of the literature; thus lacking a big picture that shows the latest status of this area. The objectives of this article is to present a survey that reflects the state of the art of Cloud service performance evaluation from the system modeling perspective. This articles also examines open issues and challenges to the surveyed evaluation approaches and identifies possible opportunities for future research in this important field.

    To analyze the relationship between health system financing and services organization models with costs and health services performance in each of Rosario's health sub-systems. The financing and organization models were characterized using secondary data. Costs were calculated using the WHO/SHA methodology. Healthcare quality was measured by a household survey (n=822). Public subsystem:Vertically integrated funding and primary healthcare as a leading strategy to provide services produced low costs and individual-oriented healthcare but with weak accessibility conditions and comprehensiveness. Private subsystem: Contractual integration and weak regulatory and coordination mechanisms produced effects opposed to those of the public sub-system. Social security: Contractual integration and strong regulatory and coordination mechanisms contributed to intermediate costs and overall high performance. Each subsystem financing and services organization model had a strong and heterogeneous influence on costs and health services performance.

    2015-01-01

    Due to the power generation industry's desire to decrease outage time and extend inspection intervals for highly stressed turbine parts, advanced and reliable Non-destructive methods were developed by Siemens Non-destructive laboratory. Effective outage performance requires the optimized planning of all outage activities as well as modern Non-destructive examination methods, in order to examine the highly stressed components (turbine rotor, casings, valves, generator rotor) reliably and in short periods of access. This paper describes the experience of Siemens Energy with an ultrasonic Phased Array inspection technique for the inspection of radial entry pinned turbine blade roots. The developed inspection technique allows the ultrasonic inspection of steam turbine blades without blade removal. Furthermore advanced Non-destructive examination methods for joint bolts will be described, which offer a significant reduction of outage duration in comparison to conventional inspection techniques.

    The objective of this study was to develop information needed to evaluate the long-term performance of concrete and reinforced concrete as a structural material for alternative LLW disposal methods. The capability to carry out such an evaluation is required for licensing a site which employs one of these alternative methods. The basis for achieving the study objective was the review and analysis of the literature on concrete and its properties, particularly its durability. In carrying out this program, criteria for evaluating performance of concrete and factors that can effect its performance were identified. The factors are both intrinsic, i.e., associated with composition of the concrete (and thus controllable), and extrinsic, i.e., due to external environmental forces such as climatic conditions and aggressive chemicals in the soil. A section of the report is devoted to the properties of coatings and their possible use in protecting concrete from chemical attack and enhancing its useful properties. The testing of concrete, using both accelerated tests and long-term non-accelerated tests, is discussed with special reference to its application to modeling of long-term performance prediction. On the basis of the study's results, minimum acceptance criteria are recommended as an aid in the licensing of disposal sites which make sure use of alternative methods

One of the route is Ciputat – Bundaran Hotel Indonesia (Tosari) and integrated with corridor 1 (one) and 8 (eight). This service is not travel on the exclusive lane or bus-way. Objective of Government Jakarta to provide this service is to decrease private car to enter the central of Jakarta. The objective of this study is to find the performance of the service. Survey have conducted static and dynamic on work day to get variable of travel time and delay, waiting time of passenger at the bus stop, headway and ridership of the bus. Service Standard Minimum of Trans-Jakarta have compared with the result of variable headway, travel speed, and waiting time at bus stop as concern of all the passengers. Analysis use correlation test method and linear regression model have done. The performance of Trans-Jakarta bus suburban service, based on travel speed indicator is fairly bad, only 8.1% of trip could comply with Minimum Service Standard. Bus performance based on the indicator of density in the bus is good, where all points are below the maximum limit i.e. 8 people/m2 at peak hour and 5 people/m2 at off-peak hour.

    2017-12-01

    Subspecialty consultation in inpatient medicine is increasing, and enhancing performance of consultation services may have a broad-reaching impact. Multisource feedback is an important tool in assessing competence and improving performance. A mechanism for primary team resident feedback on performance of consult services has not been described. We developed and evaluated an instrument designed to assess internal medicine (IM) subspecialty inpatient consult service performance. We hypothesized that the instrument would be feasible to administer and provide important information to fellowship directors. The instrument was administered in 2015 and 2016 at a single academic center. All IM residents were invited to evaluate 10 IM subspecialty consult services on 4 items and an overall satisfaction rating. The instrument allowed for free-text feedback to fellows. Program directors completed another survey assessing the impact of the consult service evaluation. A total of 113 residents responded (47 in 2015 and 66 in 2016, for a combined response rate of 35%). Each of the 4 items measured (communication, professionalism, teaching, and pushback) correlated significantly with the overall satisfaction rating in univariate and multivariate analyses. There were no differences in ratings across postgraduate year or year of administration. There was considerable variation in ratings among the services evaluated. The 7 program directors who provided feedback found the survey useful and made programmatic changes following evaluation implementation. A primary team resident evaluation of inpatient medicine subspecialty consult services is feasible, provides valuable information, and is associated with changes in consult service structure and curricula.

  17. Importance-performance analysis as a guide for hospitals in improving their provision of services.

    Whynes, D K; Reed, G

    1995-11-01

    As a result of the 1990 National Health Services Act, hospitals now compete with one another to win service contracts. A high level of service quality represents an important ingredient of a successful competitive strategy, yet, in general, hospitals have little external information on which to base quality decisions. Specifically, in their efforts to win contracts from fundholding general practitioners, hospitals require information on that which these purchasers deem important with respect to quality, and on how these purchasers assess the quality of their current service performance. The problem is complicated by the fact that hospital service quality, in itself, is multi-dimensional. In other areas of economic activity, the information problem has been resolved by importance-performance analysis and this paper reports the findings of such an analysis conducted for hosptials in the Trent region. The importance and performance service quality ratings of fundholders were obtained from a questionnaire survey and used in a particular variant of importance-performance analysis, which possesses certain advantages over more conventional approaches. In addition to providing empirical data on the determinants of service quality, as perceived by the purchasers of hospital services, this paper demonstrates how such information can be successfully employed in a quality enhancement strategy.

    Based on the laboratory investigation in FY16, for R-22 and R-410A alternative low GWP refrigerants in two baseline rooftop air conditioners (RTU), we used the DOE/ORNL Heat Pump Design Model to model the two RTUs and calibrated the models against the experimental data. Using the calibrated equipment models, we compared the compressor efficiencies, heat exchanger performances. An efficiency-based compressor mapping method was developed, which is able to predict compressor performances of the alternative low GWP refrigerants accurately. Extensive model-based optimizations were conducted to provide a fair comparison between all the low GWP candidates by selecting their preferred configurations at the same cooling capacity and compressor efficiencies.

    2010-01-01

    The literature points to possible efficiencies in local-hospital-system performance, but little is known about the internal dynamics that might contribute to this. Study of the service arrangements that nearby same-system hospitals have with one another should provide clues into how system efficiencies might be attained. The purpose of this research was to better understand the financial and operational effects of service sharing and receiving arrangements among nearby hospitals belonging to the same systems. Data are compiled for the 1,227 U.S. urban acute care hospitals that belong to multihospital systems. A longitudinal structural equation model is employed-environmental pressures and organizational characteristics in 1997 are associated with service sharing and receiving arrangements in 2000; service sharing and receiving arrangements are then associated with performance in 2003. Service sharing and receiving are measured by counts of services focal hospitals report that are not duplicated by other-system hospitals within the same county. Linear Structural Relations (LISREL) is used to estimate the model. In general, market competition from managed care and hospitals influences hospitals to exchange services. For individual hospitals, service sharing has no effects on operational efficiency and financial performance. Service receiving, however, is related to greater efficiencies and higher profits. The findings underscore the asymmetrical relationships that exist among local-system hospitals. Individual hospitals benefit from service receiving arrangements but not from sharing arrangements-it is better to receive than to give. To the extent that individual hospitals independently determine service capacities, systems may not be able to effectively rationalize service offerings.

    U.S. hospitals have been investing in high-technology medical services as a strategy to improve financial performance. Despite the interest in high-tech medical services, there is not much information available about the impact of high-tech services on financial performance. The aim of this study was to examine the impact of high-tech medical services on financial performance of U.S. hospitals by using the resource-based view of the firm as a conceptual framework. Fixed-effects regressions with 2 years lagged independent variables using a longitudinal panel sample of 3,268 hospitals (2005-2010). It was hypothesized that hospitals with rare or large numbers (breadth) of high-tech medical services will experience better financial performance. Fixed effects regression results supported the link between a larger breadth of high-tech services and total margin, but only among not-for-profit hospitals. Both breadth and rareness of high-tech services were associated with high total margin among not-for-profit hospitals. Neither breadth nor rareness of high-tech services was associated with operating margin. Although breadth and rareness of high-tech services resulted in lower expenses per inpatient day among not-for-profit hospitals, these lower costs were offset by lower revenues per inpatient day. Enhancing the breadth of high-tech services may be a legitimate organizational strategy to improve financial performance, especially among not-for-profit hospitals. Hospitals may experience increased productivity and efficiency, and therefore lower inpatient operating costs, as a result of newer technologies. However, the negative impact on operating revenue should caution hospital administrators about revenue reducing features of these technologies, which may be related to the payer mix that these technologies may attract. Therefore, managers should consider both the cost and revenue implications of these technologies.

  15. Testing OGC Web Feature and Coverage Service performance: Towards efficient delivery of geospatial data

    Directory of Open Access Journals (Sweden)

    Gregory Giuliani

    2013-12-01

    Full Text Available OGC Web Feature Service (WFS and Web Coverage Service (WCS specifications allow interoperable access to distributed geospatial data made available through spatial data infrastructures (SDIs. To ensure that a service is sufficiently responsive to fulfill users’ expectations and requirements, performance of services must be measured and monitored to track latencies, bottlenecks, and errors that may negatively influence its over- all quality. Despite the importance of data retrieval and access, little research has been published on this topic and mostly concentrates on the usability of services when integrating distributed data sources. Considering these issues, this paper extends and validates the FOSS4G approach to measure the server-side performance of different WFS and WCS services provided by various software implementations; and provides guidance to data providers looking to improve the quality of their services. Our results show that performance of tested implementations is generally satisfactory and memory tuning/data and storage optimization are essential to handle increased efficiency and reliability of services.

    Performance assessment of healthcare services is receiving greater attention due to increasing health care expenditures, greater expectations among the population, and the need to obtain results from the invested resources. Taking advantage of the existing experience of the Agència de Salut Pública de Barcelona and the Consorci Sanitari de Barcelona, which compared the healthcare services of Barcelona and Montreal, a grant from the Agència d'Avaluació de Tecnologia i Recerca Mèdiques, and the health planning interest of the Departament de Salut, the performance assessment of the Catalan healthcare service project was started in Catalonia in 2005. This article aims to present the development of the project, to provide some examples that illustrate the kind of numerical and graphical information that could be obtained and the kind of analysis that could be performed, to provide possible explanations for the results shown, and to discuss some limitations and implications. Currently, the added value of this project is that it identifies the extent to which the healthcare system is achieving its objectives, establishes a set of homogeneous indicators that could be used in the future, and is a key tool in the development of the Central de Resultats del Departament de Salut de la Generalitat de Catalunya.

    Full Text Available The study examined effects of manpower planning and development in Lagos state civil service performance. Lagos state civil service is the greatest asset of the state in its quest for socio-economic development. The primary question that was explored is whether the nature of manpower planning and development curriculum in Lagos state civil service has effect on the service performance and the attainment of state objective. The study relied on primary and secondary data, and multiple stage sampling technique was used to select the sample population. The data collected was presented in frequency bar chart and simple percentage. Pearson’s Product Moment Correlation Coefficient (PPMC statistical tool was used to test the hypotheses. Findings of the study show that the nature of manpower planning and development curriculum has a positive effect on the Lagos state civil performance. It also reveals that the manpower planning and development has a positive effect on the attainment of Lagos state objective. To achieve better performance in the service, it should among others, improve on the current manpower planning strategy and continue to update its manpower development curriculum in line with the global best practices. Given the pivotal role that technology plays in the 21st century, the service should avail itself the windows of opportunities that information technology provides in its drive to enhance employees’ skills, knowledge and abilities that will invariably improve the service performance. Yet, the service should imbibe the prescripts of New PublicManagement theory (NPM, and that goals and targets should be defined and measurable as indicators of organizational performance.

Findings: The results of our research allow us to identify that human resource management and customer relationship practices have significant effects on job satisfaction, knowledge, integration into ordinary companies and personal and social adjustment. Research limitations/implications: Data came only from one industry; therefore the results would not be directly generalized to other contexts. Practical implications: Managers in Sheltered work centers can estimate the impact of the deployment of alternative tools to mass production. Originality/value: There are few papers relating lean manufacturing tools and human resources performance indicators. At the same time, there are very few research carried out in sheltered work centers context.

    Despite the widespread use of accreditation in many countries, and prevailing beliefs that accreditation is associated with variables contributing to clinical care and organisational outcomes, little systematic research has been conducted to examine its validity as a predictor of healthcare performance. To determine whether accreditation performance is associated with self-reported clinical performance and independent ratings of four aspects of organisational performance. Independent blinded assessment of these variables in a random, stratified sample of health service organisations. Acute care: large, medium and small health-service organisations in Australia. Study participants Nineteen health service organisations employing 16 448 staff treating 321 289 inpatients and 1 971 087 non-inpatient services annually, representing approximately 5% of the Australian acute care health system. Correlations of accreditation performance with organisational culture, organisational climate, consumer involvement, leadership and clinical performance. Results Accreditation performance was significantly positively correlated with organisational culture (rho=0.618, p=0.005) and leadership (rho=0.616, p=0.005). There was a trend between accreditation and clinical performance (rho=0.450, p=0.080). Accreditation was unrelated to organisational climate (rho=0.378, p=0.110) and consumer involvement (rho=0.215, p=0.377). Accreditation results predict leadership behaviours and cultural characteristics of healthcare organisations but not organisational climate or consumer participation, and a positive trend between accreditation and clinical performance is noted.

    In order to leverage individual and organizational learning and to remain competitive in current turbulent markets it is important for employees, managers, planners and leaders to perform at high levels over time. Employee competence and skills are extremely important matters in view of the general shortage of talent and the mobility of employees with talent. Two factors emerged to have the greatest impact on the competitiveness of complex service systems: improving managerial and employee's knowledge attainment for skills, and improving the training and development of the workforce. This paper introduces the knowledge-based user-centered service design approach for sustainable skill and performance improvement in education, design and modeling of the next generation of complex service systems. The rest of the paper cover topics in human factors and sustainable business process modeling for the service industry, and illustrates the user-centered service system development cycle with the integration of systems engineering concepts in service systems. A roadmap for designing service systems of the future is discussed. The framework introduced in this paper is based on key user-centered design principles and systems engineering applications to support service competitiveness.

    2016-01-01

    Performance Management (PM) processes have become a potent part of strategic and service quality decisions in healthcare organisations. In 2005, the management of public healthcare in Ireland was amalgamated into a single integrated management body, named the Health Service Executive (HSE). Since then, the HSE has come up with a range of strategies for healthcare developments and reforms, and has developed a PM system as part of its strategic planning. The purpose of this paper is to review the application of PM in the Irish Healthcare system, with a particular focus on Irish Hospitals and Emergency Services. An extensive review of relevant HSE's publications from 2005 to 2013 is conducted. Studies of the relevant literature related to the application of PM and of international best practices in healthcare performance systems are also presented. PM and performance measurement systems used by the HSE include many performance reports designed to monitor performance trends and strategic goals. Issues in the current PM system include inconsistency of measures and performance reporting, unclear strategy alignment, and deficiencies in reporting (e.g. feedback and corrective actions). Furthermore, PM processes have not been linked adequately into Irish public hospitals' management systems. The HSE delivers several services such as mental health, social inclusion, etc. This study focuses on the HSE's PM framework, with a particular interest in acute hospitals and emergency services. This is the first comprehensive review of Irish healthcare PM since the introduction of the HSE. A critical analysis of the HSE reports identifies the shortcomings in its current PM system.

    2014-06-01

    Full Text Available There is no question that performance is the desired result of every activity or action. In order to correctly measure an organization’s performance it is necessary to select key performance indicators (KPIs that will deliver long-term value to the company. KPIs are presenting performance information for all levels of the organization and they are reflecting the progress made so far to achieve strategic objectives. The selection of the key performance indicators must be made according to the organization’s industry and activity. The company must truly understand its business and its mission. Also, KPIs must be closely linked to the strategic objectives. The focus of this research is to present effective rules for defining key performance indicators for the Service industry. This sector of economy consists in generating intangible goods like experience, expertise and information. Therefore, monitoring this type of services requires a different approach when defining performance indicators compared to the manufacturing industry.

    As lack of forage resource, alternative roughage sources have been developed for ruminant production and their inclusion would exert a great effect on the dietary nutrition, consequently affecting animal performance. Four silages (corn silage (CS), corn stalk silage (SS), inoculated CS and inoculated SS) were separately offered to 60 Bohai Black cattle (15 cattle/group) during a 24-week finishing period, in which the growth performance, carcass trait, beef quality and oxidative stability of steers were determined. Neither silage material nor silage inoculant exerted a significant effect on the growth performance, carcass trait and oxidative stability of beef cattle (P>0.05). As to beef quality, cattle offered CS had higher (P0.05) on the proximate components and fatty acids profile of beef muscle. There was neither an interaction (P>0.05) between inoculated treatment and silage material. There were no differences (P>0.05) in cholesterol content and meat quality traits in animals fed alternative silages. The collective findings suggest that it is not economical to substitute high-quality forage for relative low-quality forage in a high-concentrate finishing ration of beef cattle and silage inoculant inclusion would not exert a direct effect on animal performance.

    Full Text Available Nearly three billion people use solid fuels for cooking and heating, which leads to extremely high levels of household air pollution and is a major cause of morbidity and mortality. Many stove manufacturers have developed alternative cookstoves (ACSs that are aimed at reducing emissions and fuel consumption. Here, we tested a traditional clay chulha cookstove (TCS and five commercially available ACSs, including both natural draft (Greenway Smart Stove, Envirofit PCS-1 and forced draft stoves (BioLite HomeStove, Philips Woodstove HD4012, and Eco-Chulha XXL, in a test kitchen in a rural village of western India. Compared to the TCS, the ACSs produced significant reductions in particulate matter less than 2.5 µm (PM2.5 and CO concentrations (Envirofit: 22%/16%, Greenway: 24%/42%, BioLite: 40%/35%, Philips: 66%/55% and Eco-Chulha: 61%/42%, which persisted after normalization for fuel consumption or useful energy. PM2.5 and CO concentrations were lower for forced draft stoves than natural draft stoves. Furthermore, the Philips and Eco-Chulha units exhibited higher cooking efficiency than the TCS. Despite significant reductions in concentrations, all ACSs failed to achieve PM2.5 levels that are considered safe by the World Health Organization (ACSs: 277–714 μg/m3 or 11–28 fold higher than the WHO recommendation of 25 μg/m3.

    Full Text Available Abstract Background General practitioners (GPs can refer patients to an asthma/COPD service (AC-service for diagnostic assessment of spirometry and medical history and for asthma or COPD monitoring. The AC-service reports diagnostic results and additional information about disease burden (BORG-score for complaints, MRC-dyspnoea score, exacerbation rate, life style, medication and compliance, to the patient’s GP. This study explores how GPs use this additional information when discussing the patient’s disease burden and how this influences GPs’ information and education provision during consultations with asthma/COPD patients. Method Patients with (a suspicion of asthma or COPD were referred to an AC-service and consulted their GPs after they had received a report from the AC-service. Retrospectively patients answered questions about their GPs’ performance during these consultations. Performances were compared with performances of the same GPs during consultations without support of the AC-service (usual care, earlier that year. Results Of consultations not initiated by an AC-service check-up, 91% focussed on complaints, the initial reason for the consultation. In AC-service supported follow-up consultations, GPs explored disease burden when the (BORG-score for complaints was high - as reported by the AC-service - even when patients themselves thought it was irrelevant. GPs put significantly less effort in exploring disease burden when the Borg-score was low (BORG 3–4: 69%; BORG1-2: 51%, p = 0,01. GPs mostly ignored MRC-dyspnoea scores: attention to dyspnoea was 18% for MRC-score p = 0,63. GPs encouraged physical fitness in 13% of patients. Smoking behaviour was discussed with 66% of the actual smokers but only 14% remembered a stop smoking advice. Furthermore, pharmacotherapeutic management education in AC-service supported consultations did not differ from performance in usual care according to patient evaluations. Conclusion

    Renewed interest in proton exchange membrane fuel cell technology for space and terrestrial (particularly electric vehicles) was stimulated by the demonstration, in the mid 1980s, of high energy efficiencies and high power densities. One of the most vital components of the PEMFC is the proton conducting membrane. In this paper, an analysis is made of the performances of PEMFCs with Dupont`s Nafion, Dow`s experimental, and Asahi Chemical`s Aciplex-S membranes. Attempts were also made to draw correlations between the PEMFC performances with the three types of membranes and their physico-chemical characteristics. Practically identical levels of performances (energy efficiency, power density, and lifetime) were achieved in PEMFCs with the Dow and the Aciplex-S membranes and these performances were better than in the PEMFCs with the Nafion-115 membrane. The electrode kinetic parameters for oxygen reduction are better for the PEMFCs with the Aciplex-S and Nafion membranes than with the Dow membranes. The PEMFCs with the Aciplex-S and Dow membranes have nearly the same internal resistances which are considerably lower than for the PEMFC with the Nafion membrane. The desired membrane characteristics to obtain high levels of performance are low equivalent weight and high water content. (Author)

    2014-01-01

    Background Cancer is the leading cause of deaths in the world. A widening disparity in cancer burden has emerged between high income and low-middle income countries. Closing this cancer divide is an ethical imperative but there is a dearth of data on cancer services from developing countries. Methods This was a multi-center, retrospective observational cohort study which enrolled women with breast cancer (BC) attending 8 participating cancer centers in Malaysia in 2011. All patients were followed up for 12 months from diagnosis to determine their access to therapies. We assess care performance using measures developed by Quality Oncology Practice Initiative, American Society of Clinical Oncology/National Comprehensive Cancer Network, American College of Surgeons’ National Accreditation Program for Breast Centers as well as our local guideline. Results Seven hundred and fifty seven patients were included in the study; they represent about 20% of incident BC in Malaysia. Performance results were mixed. Late presentation was 40%. Access to diagnostic and breast surgery services were timely; the interval from presentation to tissue diagnosis was short (median = 9 days), and all who needed surgery could receive it with only a short wait (median = 11 days). Performance of radiation, chemo and hormonal therapy services showed that about 75 to 80% of patients could access these treatments timely, and those who could not were because they sought alternative treatment or they refused treatment. Access to Trastuzumab was limited to only 19% of eligible patients. Conclusions These performance results are probably acceptable for a middle income country though far below the 95% or higher adherence rates routinely reported by centres in developed countries. High cost trastuzumab was inaccessible to this population without public funding support. PMID:24650245

    Providing high service quality is one of the main functions of health systems. Measuring service quality is the basic prerequisite for improving quality. The aim of this study was to evaluate the quality of service in teaching hospitals using importance-performance analysis matrix. A descriptive-analytic study was conducted through a cross-sectional method in six academic hospitals of Qazvin, Iran, in 2012. A total of 360 patients contributed to the study. The sampling technique was stratified random sampling. Required data were collected based on a standard questionnaire (SERVQUAL). Data analysis was done through SPSS version 18 statistical software and importance-performance analysis matrix. The results showed a significant gap between importance and performance in all five dimensions of service quality (p quality gap and "responsiveness" had the lowest gap (1.97). Also, according to findings, reliability and assurance were in Quadrant (I), empathy was in Quadrant (II), and tangibles and responsiveness were in Quadrant (IV) of the importance-performance matrix. The negative gap in all dimensions of quality shows that quality improvement is necessary in all dimensions. Using quality and diagnosis measurement instruments such as importance-performance analysis will help hospital managers with planning of service quality improvement and achieving long-term goals.

  6. Peak height velocity as an alternative for maturational classification associated with motor performance

    2009-01-01

    Full Text Available Adolescence is a phase characterized by important physical and maturational alterations, with individuals of the same chronological age, but who are more mature, may present sportive advantages because of greater force gain and additional muscle mass. Thus, in studies evaluating motor skills of children and adolescents, maturational classification should be an efficient and easily applicable tool in order to facilitate the interpretation of the true relationship between maturation and motor performance. Therefore, the objective of this study was to compare the relationship between motor performance and different types of classification of biological maturation in 209 boys aged to 17 years (11.59 ± 2.57 practicing soccer. Anthropometric variables were obtained according to the ISAK criteria. Biological maturation was determined based on age at peak height velocity (PHV and also by self-assessment of sexual maturation (genitalia and pubic hair. Motor performance was evaluated by sit-and-reach tests, horizontal jump, modified push-ups, 50-m run, and 9/12-min run/walk. The results showed progression in the variables analyzed as the subjects reached maturity. Correlation analysis and the egression values indicated higher consistency for the PHV classification, which better explained motor performance according to maturational status, exceeding the values obtained by comparison according to age or sexual maturation. Thus, the use of PHV as a classification instrument is preferably recommended for youngsters with haracteristics similar to those of the present sample.

    Brown, Norman Merrill

    1998-09-01

    Historically, researchers have reported an achievement difference between females and males on standardized science tests. These differences have been reported to be based upon science knowledge, abstract reasoning skills, mathematical abilities, and cultural and social phenomena. This research was designed to determine how mastery of specific science content from public school curricula might be evaluated with performance-based assessment models, without producing gender achievement differences. The assessment instruments used were Harcourt Brace Educational Measurement's GOALSsp°ler: A Performance-Based Measure of Achievement and the performance-based portion of the Stanford Achievement Testspcopyright, Ninth Edition. The identified independent variables were test, gender, ethnicity, and grade level. A 2 x 2 x 6 x 12 (test x gender x ethnicity x grade) factorial experimental design was used to organize the data. A stratified random sample (N = 2400) was selected from a national pool of norming data: N = 1200 from the GOALSsp°ler group and N = 1200 from the SAT9spcopyright group. The ANOVA analysis yielded mixed results. The factors of test, gender, ethnicity by grade, gender by grade, and gender by grade by ethnicity failed to produce significant results (alpha = 0.05). The factors yielding significant results were ethnicity, grade, and ethnicity by grade. Therefore, no significant differences were found between female and male achievement on these performance-based assessments.

    2016-03-01

    Full Text Available The paper aims to explore the implementation of performance monitoring and evaluation tools used in Botswana’s public service. The paper also identifies achievements and challenges of implementing performance monitoring and evaluation system and suggests ways for improvement. This paper uses secondary data sources. The paper reveals lack of performance monitoring and evaluation skills, poor supervision, poor conditions of service and a poor work ethic as some of the factors contributing to ineffective use of performance monitoring and evaluation tools in the service. Leadership commitment and support, benchmarking reforms, training and education, developed administrative and governance structures as well as well-defined public policy and program formulation and implementation processes are some of the success factors to enhanced performance management and evaluation systems in Botswana. The paper argues for adoption of a developmental-led model in order to enhance existing performance monitoring and evaluation system that would improve implementation of government policies and programs. Botswana has been striving to excel in service delivery through performance monitoring and evaluation oriented reforms.

  13. Stress and performance: do service orientation and emotional energy moderate the relationship?

    Smith, Michael R; Rasmussen, Jennifer L; Mills, Maura J; Wefald, Andrew J; Downey, Ronald G

    2012-01-01

    The current study examines the moderating effect of customer service orientation and emotional energy on the stress-performance relationship for 681 U.S. casual dining restaurant employees. Customer service orientation was hypothesized to moderate the stress-performance relationship for Front-of-House (FOH) workers. Emotional energy was hypothesized to moderate stress-performance for Back-of-House (BOH) workers. Contrary to expectations, customer service orientation failed to moderate the effects of stress on performance for FOH employees, but the results supported that customer service orientation is likely a mediator of the relationship. However, the hypothesis was supported for BOH workers; emotional energy was found to moderate stress performance for these employees. This finding suggests that during times of high stress, meaningful, warm, and empathetic relationships are likely to impact BOH workers' ability to maintain performance. These findings have real-world implications in organizational practice, including highlighting the importance of developing positive and meaningful social interactions among workers and facilitating appropriate person-job fits. Doing so is likely to help in alleviating worker stress and is also likely to encourage worker performance.

    Highlights: • An alternative cathode using TiO{sub 2} nanotubes. • Determination of the structural, morphological and electronic characteristics of the cathode. • Effect of crystalline structure on MFCs performances. - Abstract: In the present work, amorphous and crystalline TiO{sub 2} nanotubes (TiNT) were fabricated via anodization and characterized as an alternative cathode for Microbial Fuel Cells (MFCs). The morphology of TiNT is characterized by scanning electron microscopy (SEM). The crystalline structure and chemical composition are examined by X-ray diffraction (XRD) and Energy dispersive X-ray spectroscopy (EDX). The electrical conductivity characteristics were examined by electrochemical impedance spectroscopy (EIS). MFCs based on the alternative cathodes were evaluated in terms of energy generation and wastewater treatment. The performances of the as-anodized nanotubes and TiNT annealed at 450 °C and at 550 °C were investigated in double-chamber MFCs with carbon rod and graphite granules as anode and polymer inclusion membrane based on ionic liquid as separator. Industrial wastewater was the source of carbon and inoculum for the experiments. The as grown amorphous nanotubes exhibited the best output power density of 15.16 mWm{sup −2}. The results reported here indicate that the specific surface area and the oxygen vacancies of the TiNT cathode can influence the MFCs performance together, because both factors play crucial role in the oxygen reduction reaction (ORR). As-anodized TiNT, due to its higher specific surface provide more active sites for electrode reactions. The final oxygen demand (COD) for all systems achieved a COD removal within the interval 54–71% after 10 days. This approved the suitability of MFCs for wastewater treatment.

Ejector has been modeled by considering experimental data based correlations of component efficiencies to take care of all irreversibilities. Ejector area ratio has been optimized based on maximum coefficient of performance (COP for typical air-conditioner operating temperatures. Selected refrigerants have been compared based on area ratio, pressure lift ratio, entrainment ratio, COP, COP improvement and volumetric cooling capacity. Effects of normal boiling point and critical point on the performances have been studied as well. Using ejector as an expansion device, maximum improvement in COP is noted in R1234yf (10.1%, which reduces the COP deviation with R134a (4.5% less in basic cycle and 2.5% less in ejector cycle. Hence, R1234yf seems to be best alternative for ejector expansion system due to its mild flammability and comparable volumetric capacity and cooling COP. refrigerant R161 is superior to R134a in terms of both COP and volumetric cooling capacity, although may be restricted for low capacity application due to its flammability.

    Full Text Available Background: This study investigates the role of an incremental change in organizational process in creating radical performance results in a service provider company. The role of Kaizen is established prominently in manufacturing, but is nascent in service applications. This study examines the impact of introducing Kaizen as an ODI tool-how it is applied, how it works, and whether participants believe it helps service groups form more effective working relationships that result in significant performance improvements. Methods: Exploring the evolving role of Kaizen in service contexts, this study explores a variety of facets of human communication in the context of continuous improvement and teamwork inter-organizationally. The paper consists of an archival study and an action research case study. A pre-intervention study consisting of observations, interviews, and submission of questionnaires to employees of a manufacturing and air-sea freight firm was conducted. A Kaizen intervention occurred subsequently, and a post-intervention study was then conducted. Results: Radical improvements in both companies such as 30% financial growth, 81% productivity improvement and more are demonstrated in this paper. Conclusions: Findings offer unique insights into the effects of Kaizen in creating radical performance improvements in a service company and its customer. Both qualitative and quantitative results of business, satisfaction, and productivity suggest time invested in introducing Kaizen into a service organization helps the companies improve relationships and improve the bottom line dramatically.

    Background Poor service user experiences are often reported on mental health inpatient wards. Crisis houses are an alternative, but evidence is limited. This paper investigates therapeutic alliances in acute wards and crisis houses, exploring how far stronger therapeutic alliance may underlie greater client satisfaction in crisis houses. Methods and Findings Mixed methods were used. In the quantitative component, 108 crisis house and 247 acute ward service users responded to measures of satisfaction, therapeutic relationships, informal peer support, recovery and negative events experienced during the admission. Linear regressions were conducted to estimate the association between service setting and measures, and to model the factors associated with satisfaction. Qualitative interviews exploring therapeutic alliances were conducted with service users and staff in each setting and analysed thematically. Results We found that therapeutic alliances, service user satisfaction and informal peer support were greater in crisis houses than on acute wards, whilst self-rated recovery and numbers of negative events were lower. Adjusted multivariable analyses suggest that therapeutic relationships, informal peer support and negative experiences related to staff may be important factors in accounting for greater satisfaction in crisis houses. Qualitative results suggest factors that influence therapeutic alliances include service user perceptions of basic human qualities such as kindness and empathy in staff and, at service level, the extent of loss of liberty and autonomy. Conclusions and Implications We found that service users experience better therapeutic relationships and higher satisfaction in crisis houses compared to acute wards, although we cannot exclude the possibility that differences in service user characteristics contribute to this. This finding provides some support for the expansion of crisis house provision. Further research is needed to investigate why acute

  6. Economic and environmental performance of alternative policy measures to reduce nutrient surpluses in Finnish agriculture

    Directory of Open Access Journals (Sweden)

    H. LEHTONEN

    2008-12-01

    Full Text Available This paper provides an economic sector level analysis of the effectiveness of different policy measures in decreasing nitrogen (N and phosphorus (P surpluses from agriculture in order to reduce nutrient runoff from agricultural fields to watercourses and to improve water quality of surface waters. Assuming no changes in the EU level policies after CAP reform 2003 we focus on national level policy measures such as full or partial de-coupling of national support from production, payments for reduced nutrient surpluses of N and P, and N fertiliser tax. None of the analysed policy measures is superior one with respect to environmental performance, since full decoupling of national support would be the most effective in reducing P surpluses while payment for reduced nutrient surplus performed best with respect to N surpluses. Economic performance (farmers’ compliance cost per %-reduction of N or P surplus of full and partial de-coupling of national support is clearly better than that of specialised agri-environmental policy instruments, because both decoupling scenarios result in the increase of farmers’ income in comparison to base scenario, and thus compliance costs are in fact negative in these two cases. Our analysis confirms the fact that the overall policy package matters a lot for the effectiveness of agrienvironmental policy measures. Environmental performance of agri-environmental policy measures may be significantly reduced, if they are implemented jointly with production coupled income support policies. Thus, in order to increase the effectiveness of agri-environmental policy measures agricultural income support policies should be decoupled from production and this alone would bring substantial reduction in nutrient surpluses.;

    2011-12-01

    Full Text Available An experimental analysis was done using a four-stroke, single cylinder, constant speed, water-cooled diesel engine, which was interfaced with Engine software. Performance and emission characteristics were evaluated for three non-edible vegetable oils, i.e. thumba, jojoba, neem oil, as well as jojoba methyl ester, to study the effect of injection pressure at 205, 220, 240 and 260 bar with a variation in injection timing at 23°bTDC and 28°bTDC. The performance of jojoba methyl ester improved with an increase in injection pressure. A maximum brake thermal efficiency of 29.72% was obtained with lower emissions compared to the other vegetable oils; this might be explained by low viscosity and better combustion. Further investigations were carried out with a new lubricant, SAE 5W-30, which improved the performance of the CI engine by 1.59%. All of the abovementioned investigations were fruitful and these results are expected to lead to substantial contributions in the development of a viable vegetable oil engine.

    Highlights: • A thermal model for a single-tube Fresnel receiver has been developed. • A comparative analysis based on different design parameters, has been carried out. • A comparative analysis based on different working fluids, has been carried out. • The receiver thermal performance is characterized by energy and exergy efficiencies. - Abstract: Although most of recent commercial Solar Thermal Power Plants (STPP) installed worldwide are parabolic trough plants, it seems that Linear Fresnel Collectors (LFC) are becoming an attractive option to generate electricity from solar radiation. Contrary to parabolic trough collectors, the design of LFC receivers has many degrees of freedom, and two basic designs can be found in the literature: single-tube and multi-tube design. This article studies the single-tube design, for which a thermal model has been developed. This model has been thought to be accurate enough to characterize the heat transfer in a non-elementary geometry and flexible enough to support changes of the characteristic parameters in the receiver design. The thermal model proposed is based on a two-dimensional, steady-state energy balance, in the receiver cross section and along its length. One of the features of the model is the characterization of the convective and radiative heat transfer in the receiver cavity, as it is not an elementary geometry. Another feature is the possibility of studying the receiver performance with different working fluids, both single-phase or two-phase. At last, the receiver performance has been characterized by means of the energy and exergy efficiency. Both variables are important for a complete receiver thermal analysis, as will be shown in the paper. The model has been first applied to the comparative study of the thermal performance of LFC receivers based on the value of some parameters: selective coating emissivity in the tube and inlet fluid thermal properties, for the case of using water/steam.

  11. Development of a new quality fair access best value performance indicator (BVPI) for recycling services.

    2008-01-01

    Recycling schemes are being used worldwide to reduce the impact of municipal waste. Those using public funds are usually obliged to set performance indicators by which the standards of such schemes can be measured. In the UK, a set of statutory Best Value Performance Indicators (BVPI) must be reported annually, such as the Quality of Fair Access, which monitors the public's access to recycling facilities within 1000 m (known as BVPI 91). This work shows that BVPI 91, and performance indicators like it, quantify only very basic recycling services. A much more sensitive performance indicator is developed in this paper, labelled as the Maximum Practicable Recycling Rate Provision (MPRRP) achievable by a local authority. It indicates the percentage of local waste that could be reasonably recycled using the services provided, calculated on the basis of the average composition of the local waste, the local population coverage for collection of any materials, and nationally provided information stating how much of each material stream is generally suitable (practical) for recycling. Evidence for the usefulness of this new quantity is presented. Although this paper refers a particular performance indicator in the UK, its findings are applicable to all urban areas worldwide needing to monitor recycling service. Furthermore, the MPRRP could be used for planning purposes, and for determining the level of performance of an existing service, by comparing its predicted recycling rate to that actually obtained. Further work is now being carried out on this.

  12. A Fast Optimization Method for Reliability and Performance of Cloud Services Composition Application

    2013-01-01

    Full Text Available At present the cloud computing is one of the newest trends of distributed computation, which is propelling another important revolution of software industry. The cloud services composition is one of the key techniques in software development. The optimization for reliability and performance of cloud services composition application, which is a typical stochastic optimization problem, is confronted with severe challenges due to its randomness and long transaction, as well as the characteristics of the cloud computing resources such as openness and dynamic. The traditional reliability and performance optimization techniques, for example, Markov model and state space analysis and so forth, have some defects such as being too time consuming and easy to cause state space explosion and unsatisfied the assumptions of component execution independence. To overcome these defects, we propose a fast optimization method for reliability and performance of cloud services composition application based on universal generating function and genetic algorithm in this paper. At first, a reliability and performance model for cloud service composition application based on the multiple state system theory is presented. Then the reliability and performance definition based on universal generating function is proposed. Based on this, a fast reliability and performance optimization algorithm is presented. In the end, the illustrative examples are given.

    In earlier papers, discussions of the mechanisms which are important in performance assessment in fractured media are given. The influence of the mechanisms have been demonstrated using CHAN3D. In this study CHAN3D has been used to simulate production of input data to COMP23 and FARF31. CHAN3D has been integrated with COMP23 in earlier studies, but it has not been used before to calculate input data to FARF31. In the normal use of CHAN3D, the transport part of the concept simulates far field migration. The task in this study was to produce input data according to a specification and using a defined hypothetical repository located at Aespoe HRL as a platform. During the process of applying CHAN3D to the site, the scaling of conductivity was studied, using both data from Aespoe HRL and synthetic data. From the realisations performed, ensemble statistics of water travel time, flux at repository scale, flow-wetted surface and F-ratio values were calculated. Two typical realisations were studied in more detail. The results for three specified canister positions were also highlighted. Exit locations for the released particles were studied. In each realisation statistics were calculated over the entities. The values were post-processed to obtain performance measures of higher order. From the averaging over all the realisations it can be concluded that the Monte Carlo stability is reached for the ensemble statistics. The presence of fracture zones has a large influence on flow and transport in the rock. However, for a single canister the result may be very different between realisations. In some realisations there may be a fast path to a fracture zone whereas in other realisations the opposite may be valid. From the calculation of the flow over the boundaries between the regional model and the smaller local model the consistency seem to be acceptable considering that a perfect match of properties is hard to obtain

    Paying for performance provides financial rewards to medical care providers for improvements in performance measured by utilization and quality of care indicators. In 2006, Rwanda began a pay for performance scheme to improve health services delivery, including HIV/AIDS services. Using a prospective quasi-experimental design, this study examines the scheme's impact on individual and couples HIV testing. We find a positive impact of pay for performance on HIV testing among married individuals (10.2 percentage points increase). Paying for performance also increased testing by both partners by 14.7 percentage point among discordant couples in which only one of the partners is an AIDS patient. Copyright © 2014.

    2007-06-01

    Performance assessments for the Area 5 Radioactive Waste Management Site on the Nevada Test Site have used three different mathematical models to estimate Rn-222 flux density. This study describes the performance, uncertainty, and sensitivity of the three models which include the U.S. Nuclear Regulatory Commission Regulatory Guide 3.64 analytical method and two numerical methods. The uncertainty of each model was determined by Monte Carlo simulation using Latin hypercube sampling. The global sensitivity was investigated using Morris one-at-time screening method, sample-based correlation and regression methods, the variance-based extended Fourier amplitude sensitivity test, and Sobol's sensitivity indices. The models were found to produce similar estimates of the mean and median flux density, but to have different uncertainties and sensitivities. When the Rn-222 effective diffusion coefficient was estimated using five different published predictive models, the radon flux density models were found to be most sensitive to the effective diffusion coefficient model selected, the emanation coefficient, and the radionuclide inventory. Using a site-specific measured effective diffusion coefficient significantly reduced the output uncertainty. When a site-specific effective-diffusion coefficient was used, the models were most sensitive to the emanation coefficient and the radionuclide inventory.

    The performance characteristics of several propulsion technologies applied to piloted Mars missions are compared. The characteristics that are compared are Initial Mass in Low Earth Orbit (IMLEO), mission flexibility, and flight times. The propulsion systems being compared are both demonstrated and envisioned: Chemical (or Cryogenic), Nuclear Thermal Rocket (NTR) solid core, NTR gas core, Nuclear Electric Propulsion (NEP), and a mirror fusion space propulsion system. The proposed magnetic mirror fusion reactor, known as the Mirror Fusion Propulsion System (MFPS), is described. The description is an overview of a design study that was conducted to convert a mirror reactor experiment at Lawrence Livermore National Lab (LLNL) into a viable space propulsion system. Design principles geared towards minimizing mass and maximizing power available for thrust are identified and applied to the LLNL reactor design, resulting in the MFPS. The MFPS' design evolution, reactor and fuel choices, and system configuration are described. Results of the performance comparison shows that the MFPS minimizes flight time to 60 to 90 days for flights to Mars while allowing continuous return-home capability while at Mars. Total MFPS IMLEO including propellant and payloads is kept to about 1,000 metric tons. 50 refs

    Full Text Available Direct seeded rice is promising alternative to traditional transplanting, but requires appropriate crop and water management to maintain yield performance and achieve high water productivity. Present study evaluated the effect of seed priming and irrigation on crop establishment, tillering, agronomic traits, paddy yield, grain quality and water productivity of direct seeded rice in alternate wetting and drying (DSR-AWD in comparison with direct seeded rice at field capacity (DSR-FC. Seed priming treatments were osmo-priming with KCl (2.2%, CaCl2 (2.2% and moringa leaf extracts (MLE, 3.3% including hydro-priming as control. Among the treatments, seed osmo-primed with MLE emerged earlier and had higher final emergence, followed by osmo-priming with CaCl2. Tillering emergence rate and number of tillers per plant were the highest for seed priming with CaCl2 in DSR-AWD. Total productive and non-productive tillers, panicle length, biological and grain yields, harvest index were highest for seed priming with MLE or CaCl2 in DSR-AWD. Similarly, grain quality, estimated in terms of normal grains, abortive and chalky grains, was also the highest in DSR-AWD with MLE osmo-priming. Benefit cost ratio and water productivity was also the highest in DSR-AWD for seed priming with MLE. In conclusion, seed priming with MLE or CaCl2 can be successfully employed to improve the direct seeded rice performance when practiced with alternate wetting and drying irrigation.

    Full Text Available We analyse a panel data set covering the years 2001 to 2005 and comprised of a stratified sample of A, AB and AH non financial companies listed on China’s Shanghai and Shenzhen stock exchanges to provide empirical evidence on the influence of corporate control and governance characteristics on the quality and independence of corporate decision making in these companies. The characteristics considered are the level of concentration in and type of ownership of the companies, particularly high levels of government and foreign ownership, and the composition (expertise and size of the companies’ two boards. Performance outcomes, and by association the quality and independence of corporate policy decisions, are measured in the form of firm bad debt to accounts receivable ratio (BD/AR. We find that for our sample firms’ concentration of ownership, including state and foreign ownership, and board size and independence are significant factors in determining the levels of the bad debt ratio.

    Full Text Available The potential of information technology (IT as an enabler of customer service process continues to generate interest, which is reflected in the large number of IT-related studies. In spite of the significant progress made in this area, research findings have been mixed and inconsistent. Also, the underlying mechanisms by which IT can affect customer service process remain underexamined. The aim of this study was to find out whether IT investments and IT managerial capabilities can account for variations in customer service performance among insurance companies in Nigeria. Using survey research design, the three formulated hypotheses were tested with data gathered from 402 staff at the managerial level drawn from the selected insurance companies in Nigeria, which have been among the largest investors in IT, and where customer service is widely perceived as strategically important. Responses were analyzed using linear regression. A major finding of this study is that IT is a necessary, but not sufficient, condition for sustainable competitive advantage in customer service. Results show that the interaction of IT investments and tacit, path-dependent, and firm-specific IT managerial capabilities significantly explains variations in customer service performance. Consequently, this study recommends that to realize IT-business value, investments in IT should be accompanied by building and developing IT managerial capabilities.

    Urodynamics (UDS) is widely used for the diagnosis of lower urinary tract dysfunction. Air-Charged catheters (ACC), one of the newer technologies for UDS pressure recording, has been adopted in growing numbers around the world for the past 15 years. Currently, there is a lack of published studies characterizing specific performance of the ACC. Since linearity, hysteresis, pressure drift, and frequency response are important components in characterizing accuracy for catheter-manometer systems; this study aimed to assess these four aspects in ACC. A total of 180 T-DOC® ACC were used in three different laboratory settings to assess pressure linearity and hysteresis (15 dual-sensor vesical and urethral and 30 single-sensor abdominal), pressure drift over 2 h (115 single-sensor), and frequency response (20 single-sensor). Data are presented as mean ± standard deviation. ACC showed linearity of 0.99 ± 0.01, 0.99 ± 0.01, and 1.01 ± 0.01; and hysteresis of 0.57 ± 0.3%, 0.76 ± 0.48%, and 1 ± 0.89% for the abdominal, vesical, and urethral sensors, respectively. A pressure drift of 2.2 ± 1.4% at 1 h and 4.4 ± 2.5% at 2 h were observed when compared to baseline pressures. The catheters did not show any amplification factor during the sweep from 1 to 30 Hz, and recorded signals up to 5 Hz attenuating higher frequency signals. In this study the T-DOC® ACC showed a linear performance with minimal hysteresis associated with acceptable pressure drift, and adequate frequency response to capture clinically relevant pressures. The accurate results observed in this study suggest that these catheters are technically suitable to be used as a measuring instrument for UDS. © 2017 Wiley Periodicals, Inc.

    Highlights: • Variation of the stream properties in the syngas-fueled hybrid SOFC–GT cycle. • Detailed analysis of the operation of the methane-fueled SOFC–GT cycle. • Investigate effects of inlet fuel type and composition on performance of cycle. • Comparison of system operation when operated with and without anode recirculation. - Abstract: In this paper, the hybrid solid oxide fuel cell (SOFC) and gas turbine (GT) model was applied to investigate the effects of the inlet fuel type and composition on the performance of the cycle. This type of analysis is vital for the real world utilization of manufactured fuels in the hybrid SOFC–GT system due to the fact that these fuel compositions depends on the type of material that is processed, the fuel production process, and process control parameters. In the first part of this paper, it is shown that the results of a limited number of studies on the utilization of non-conventional fuels have been published in the open literature. However, further studies are required in this area to investigate all aspects of the issue for different configurations and assumptions. Then, the results of the simulation of the syngas-fueled hybrid SOFC–GT cycle are employed to explain the variation of the stream properties throughout the cycle. This analysis can be very helpful in understanding cycle internal working and can provide some interesting insights to the system operation. Then, the detailed information of the operation of the methane-fueled SOFC–GT cycle is presented. For both syngas- and methane-fueled cycles, the operating conditions of the equipment are presented and compared. Moreover, the comparison of the characteristics of the system when it is operated with two different schemes to provide the required steam for the cycle, with anode recirculation and with an external source of water, provides some interesting insights to the system operation. For instance, it was shown that although the physical

    Full Text Available Because of its specificity, service quality is difficult to assess, especially since there is no materiality in it, it cannot be seen. Usually the gap between the expectations of customer and their perceptions in relation to a particular service is observed. This article aim is to evaluate the quality of catering services offered by one of the breweries (restaurant in Silesia. The importance-performance analysis, which is often underestimated, was used in order to show its advantages. The survey was conducted among 137 customers of the selected brewery in Czestochowa. The average values of evaluations of all individual questions from both parts of survey were calculated. Then, average values for the pair of statements (performance; importance were placed in the importance-performance map. The analysis revealed that the service quality of the research brewery is placed in quadrant II, i.e. the area of reasonable property of needs. This means that the improvement of service quality is not necessary.

  14. Applying Service Performance Guarantees to Reduce Risk Perception in the Purchase and Consumption of Higher Education

    Directory of Open Access Journals (Sweden)

    Nooraini Mohamad Sheriff

    2006-12-01

    Full Text Available The intangible nature of education is one contributor to consumers’ perception of risk prior to their purchase and consumption. This risk includes: functional risk, financial risk, temporal risk, physical risk, psychological risk and social risk. The presence of these risks often makes consumer evaluation prior to purchase and consumption difficult. Invoking a service guarantee is a platform available to enable higher educational institutions to minimize such risk perception so as to induce purchase. Specifically, service guarantee for higher education entails the application of teaching performance guarantee. This form of guarantee focuses on two important customer groups of higher educational institutions namely, students and faculty members, and focuses only on a specific performance aspect such as instructor’s performance. Thus, if students are dissatisfied with an instructor’s performance they are entitled to receive their money back. The imposition of such a teaching performance guarantee would implicate instructor’s accountability for certain aspects of their performance. It also establishes a mechanism to solicit feedback to better understand why and how instructors fail. Consequently, service performance guarantee creates a high level of customer focus and signals instructors’ care towards students

    Nozzles with large and small dimensions are widely used in various industries. The main objective of this research is to investigate the effects of dimensional size and surface roughness on the service performance of a micro Laval nozzle. The variation of nozzle service performance from the conventional macro to micro scale is presented in this paper. This shows that the dimensional nozzle size has a serious effect on the nozzle gas flow friction. With the decrease of nozzle size, the velocity performance and thrust performance deteriorate. The micro nozzle performance has less sensitivity to the variation of surface roughness than the large scale nozzle does. Surface quality improvement and burr prevention technologies are proposed to reduce the friction effect on the micro nozzle performance. A novel process is then developed to control and depress the burr generation during micro nozzle machining. The polymethyl-methacrylate as a coating material is coated on the rough machined surface before finish machining. Finally, the micro nozzle with a throat diameter of 1 mm is machined successfully. Thrust test results show that the implement and application of this machining process benefit the service performance improvement of the micro nozzle. (paper)

    Lysozyme is a 1,4-β-N-acetylmuramidase that has antimicrobial properties. The objective of this experiment was to determine if lysozyme in nursery diets improved growth performance and gastrointestinal health of pigs weaned from the sow at 24 d of age. Two replicates of 96 pigs (192 total; 96 males, 96 females) were weaned from the sow at 24 d of age, blocked by BW and gender, and then assigned to 1 of 24 pens (4 pigs/pen). Each block was randomly assigned 1 of 3 dietary treatments for 28 d: control (two 14-d phases), control + antibiotics (carbadox/copper sulfate), or control + lysozyme (100 mg/kg diet). Pigs were weighed and blood sampled on d 0, 14, and 28 of treatment. Blood was analyzed for plasma urea nitrogen (PUN) and IgA. At 28 d, pigs were killed, and samples of jejunum and ileum were collected and fixed for intestinal morphology measurements. An additional jejunum sample was taken from the 12 pigs with the median BW per treatment to determine transepithelial electrical resistance (TER). Pigs consuming antibiotics or lysozyme grew at a faster rate than control pigs (0.433 ± 0.009 and 0.421 ± 0.008 vs. 0.398 ± 0.008 kg/d, respectively; P 0.48), but G:F was improved in pigs consuming antibiotics or lysozyme (0.756 ± 0.014, 0.750 ± 0.021, and 0.695 ± 0.019 kg/kg; P 0.48). Dietary treatment did not affect TER (P > 0.37), but gilts had lower TER compared with barrows (P 0.53). However, jejunum villi height was increased and crypt depth was decreased in pigs consuming antibiotics or lysozyme (P pigs weaned from the sow at 24 d of age.

    Climate change impacts on air temperatures and water availability have the potential to alter future electricity sector investment decisions as well as the reliability and performance of the power sector. Different electricity sector configurations are more or less vulnerable to climate-induced changes. For example, once-through cooled thermal facilities are the most cost-effective and efficient technologies under cooler and wetter conditions, but can be substantially affected by and vulnerable to warmer and drier conditions. Non-thermal renewable technologies, such as PV and wind, are essentially "drought-proof" but have other integration and reliability challenges. Prior efforts have explored the impacts of climate change on electric sector development for a limited set of climate and electricity scenarios. Here, we provide a comprehensive suite of scenarios that evaluate how different electricity sector pathways could be affected by a range of climate and water resource conditions. We use four representative concentration pathway (RCP) scenarios under five global circulation models (GCM) as climate drivers to a Water Balance Model (WBM), to provide twenty separate future climate-water conditions. These climate-water conditions influence electricity sector development from present day to 2050 as determined using the Regional Energy Deployment Systems (ReEDS) model. Four unique electricity sector pathways will be considered, including business-as-usual, carbon cap, high renewable energy technology costs, and coal reliance scenarios. The combination of climate-water and electricity sector pathway scenarios leads to 80 potential future cases resulting in different national and regional electricity infrastructure configurations. The vulnerability of these configurations in relation to climate change (including in-stream thermal pollution impacts and environmental regulations) is evaluated using the Thermoelectric Power and Thermal Pollution (TP2M) model, providing

    Nanocomposites can be considered safe during their life cycle as long as the nanofillers remain embedded in the matrix. Therefore, a possible release of nanofillers has to be assessed before commercialization. This report addresses possible life cycle release scenarios for carbon nanotubes (CNT), graphene, and carbon black (CB) from a thermoplastic polyurethane (TPU) matrix. The content of each nanofiller was adjusted to achieve the same conductivity level. The nanofillers reduced the rate of nanoscale releases during mechanical processing with decreasing release in the order neat TPU, TPU-CNT, TPU-graphene, and TPU-CB. Released fragments were dominated by the polymer matrix with embedded or surface-protruding nanofillers. During electron microscopy analysis, free CB was observed, however, there was no free CNT or graphene. Quantitatively, the presence of free nanofillers remained below the detection limit of <0.01% of generated dust. Further, both the production process and type of mechanical processing showed a significant impact with higher release rates for injection-molded compared to extruded and sanded compared to drilled materials. Due to its optimal performance for further development, extruded TPU-CNT was investigated in a combined, stepwise worst case scenario (mechanical processing after weathering). After weathering by simulated sunlight and rain, CNT were visible at the surface of the nanocomposite; after additional sanding, fragments showed protruding CNT, but free CNT were not detected. In summary, this preliminary exposure assessment showed no indication that recommended occupational exposure limits for carbonaceous nanomaterials can be exceeded during the life cycle of the specific TPU nanocomposites and conditions investigated in this study.

  19. Assessing the Sustainability Performance of Urban Plans based on Ecosystem Services

    Aiming at efficient and mindful use of natural resources while enabling social cohesion and economic development; sustainable development is one of the most emerging phenomenon in last decade. In this regard, role of urban development is critical by means of achieving sustainability since more than half of the world's population lives in cities. However, there is no solid and widely accepted approach for sustainability assessment in land use planning because there is not enough evidence on the relation between land use plans and environmental sustainability. With the basic aim of setting up relation between environmental sustainability and urban plans, this study utilizes ecosystem services phenomenon to define sustainability performance of a land use plan. Since ecosystem services can easily be related with land cover and land use they can be used as an efficient tool to act as indicators of sustainability. Meanwhile, while urban plans can provide ecosystem services and their level of service provision can be quantified, this is not solely enough for understanding its sustainability. Because it is also known that a land use plan mostly has negative impact on sustainability. Hence, this study embraces land use plans as a source of ecosystem services and environmental impacts. The difference between these entities are assumed to be the sustainability performance of a plan. The analysis relies on four parameters: ecosystem service capacity (environmental impact capacity), areal quantity of a land cover / use function, fragmantation level of the land use / cover and weight of ecosystem services / environmental impacts. Lastly, this approach is adopted for Istanbul's environmental master plan of 2009 and actual land cover of the same period. By calculating both data's environmental performance, the change of sustainability level sourced from environmental plan is analyzed.
