  4. Options for pricing ancillary services in a deregulated power system

    Yamin, Hatim Yahya

    2001-07-01

    GENCOs in restructured systems are compensated for selling energy in the market. In a restructured market, a mechanism is required to entice participants in the market to provide ancillary services and to ensure adequate compensation that would guarantee its economic viability. The ISO controls the dispatch of generation, manages the reliability of the transmission grid, provides open access to the transmission, buys and provides ancillary services as required, coordinates day-ahead, hour-ahead schedules and performs real time balancing of load and generation, settles real time imbalances and ancillary services sales and purchases. The ISO, also, administers congestion management protocols for the transmission grid. Since the ISO does not own any generating units it must ensure that there is enough reserves for maintaining reliability according to FERC regulations, and sufficient unloaded generating capacity for balancing services in a real-time market. The ISO could meet these requirements by creating a competitive market for ancillary services, which are metered and remain unbundled to provide an accurate compensation for each supplier and cost to each consumer, In this study, we give an overview for restructuring and ancillary services in a restructured power marketplace. Also, we discuss the effect of GENCOs' actions in the competitive energy and ancillary service markets. In addition, we propose an auction market design for hedging ancillary service costs in California market. Furthermore, we show how to include the n-1 and voltage contingencies in security constrained unit commitment. Finally, we present two approaches for GENCOs' unit commitment in a restructured power market; one is based on game theory and the other is based on market price forecasting. In each of the two GENCOs' unit commitment approaches, we discuss the GENCOs' optimal bidding strategies in energy and ancillary service markets to maximize the GENCOs' profit.

    Bert, Jack M

    2008-01-01

    The delivery of high quality medical services is approaching a crisis situation in the United States. As physician reimbursements decline and overhead increases, orthopedic surgeons must seek additional sources of revenue to remain financially viable and control the quality of medical care that they deliver. The orthopedic surgeon group is well positioned to control its own service lines and deliver excellent patient care as a result. This article reviews the possibilities of multiple types of ancillary service lines available for the orthopedic group practice. PMID:18061762

    In addition to providing energy to end-consumers, power system operators are also responsible for ensuring system reliability. To this end, power markets maintain an array of ancillary services to ensure it is always possible to balance the supply and demand for energy in real-time. A subset of these ancillary services are commonly procured through market-based mechanisms: namely, Regulation, Spinning, and Non-spinning Reserves.

  11. Using OWL-S to annotate services with ancillary behaviour

    Belecheanu, R A; Jacyno, M; Payne, T.

    2004-01-01

    This paper introduces the concept of services with ancillary behaviour and illustrates the use of OWL-S to semantically describe them. The OWL-S syntax used reflects the dynamic and core-function independent nature of ancillary behaviour. The approach is illustrated on the case of a ubiquitous computing system designed to offer care in the home of a cardiac patient. Here one of the challenges is to ensure service availability, team awareness and transaction atomicity. The concept of commitmen...

  12. Integration of Flexible Consumers in the Ancillary Service Markets

    Biegel, Benjamin; Westenholz, Mikkel; Hansen, Lars Henrik;

    2014-01-01

    Flexible consumption devices are often able to quickly adjust the power consumption making these devices very well suited as providers of fast ancillary services such as primary and secondary reserves. As these reserves are among the most well-paid ancillary services, it is an interesting idea...... to let an aggregator control a portfolio of flexible consumption devices and sell the accumulated flexibility in the primary and secondary reserve markets. However, two issues make it difficult for a portfolio of consumption devices to provide ancillary services: First, flexible consumption devices only...... have a limited energy capacity and are therefore not able to provide actual energy deliveries. Second, it is often difficult to make an accurate consumption baseline estimate for a portfolio of flexible consumption devices. These two issues do not fit the current regulations for providing ancillary...

  13. The evolving design of RTO ancillary service markets

    Although the markets for ancillary services at the North American Independent System Operators are often structured in quite different ways there is an emerging set of core design elements that represent a rough consensus as to what the optimal design configuration for ancillary services should be, albeit with some regional variation. This paper looks back at how the design of ancillary services markets has recently evolved to put this development in context. Thereafter it examines the methods by which ancillary services are procured by highlighting the procurement practices at a number of different Independent System Operators, principally those in California, New York, New England, Texas and the PJM Interconnection, in an attempt to tease out the remaining reasons why the ancillary service markets are still so different. This is important as there are many innovations that are not rooted in regional differences but reflect genuine technical advances and economic efficiency gains and can be replicated across other ISOs to produce more efficient designs, greater reliability and lower costs.

  14. Loads Providing Ancillary Services: Review of International Experience

    Heffner, Grayson; Goldman, Charles; Kintner-Meyer, Michael

    2007-05-01

    In this study, we examine the arrangements for and experiences of end-use loads providing ancillary services (AS) in five electricity markets: Australia, the United Kingdom (UK), the Nordic market, and the ERCOT and PJM markets in the United States. Our objective in undertaking this review of international experience was to identify specific approaches or market designs that have enabled customer loads to effectively deliver various ancillary services (AS) products. We hope that this report will contribute to the ongoing discussion in the U.S. and elsewhere regarding what institutional and technical developments are needed to ensure that customer loads can meaningfully participate in all wholesale electricity markets.

  15. Optimal generator bidding strategies for power and ancillary services

    Morinec, Allen G.

    As the electric power industry transitions to a deregulated market, power transactions are made upon price rather than cost. Generator companies are interested in maximizing their profits rather than overall system efficiency. A method to equitably compensate generation providers for real power, and ancillary services such as reactive power and spinning reserve, will ensure a competitive market with an adequate number of suppliers. Optimizing the generation product mix during bidding is necessary to maximize a generator company's profits. The objective of this research work is to determine and formulate appropriate optimal bidding strategies for a generation company in both the energy and ancillary services markets. These strategies should incorporate the capability curves of their generators as constraints to define the optimal product mix and price offered in the day-ahead and real time spot markets. In order to achieve such a goal, a two-player model was composed to simulate market auctions for power generation. A dynamic game methodology was developed to identify Nash Equilibria and Mixed-Strategy Nash Equilibria solutions as optimal generation bidding strategies for two-player non-cooperative variable-sum matrix games with incomplete information. These games integrated the generation product mix of real power, reactive power, and spinning reserve with the generators's capability curves as constraints. The research includes simulations of market auctions, where strategies were tested for generators with different unit constraints, costs, types of competitors, strategies, and demand levels. Studies on the capability of large hydrogen cooled synchronous generators were utilized to derive useful equations that define the exact shape of the capability curve from the intersections of the arcs defined by the centers and radial vectors of the rotor, stator, and steady-state stability limits. The available reactive reserve and spinning reserve were calculated given a

  16. Demand Response Resources for Energy and Ancillary Services (Presentation)

    Hummon, M.

    2014-04-01

    Demand response (DR) resources present a potentially important source of grid flexibility particularly on future systems with high penetrations of variable wind an solar power generation. However, DR in grid models is limited by data availability and modeling complexity. This presentation focuses on the co-optimization of DR resources to provide energy and ancillary services in a production cost model of the Colorado test system. We assume each DR resource can provide energy services by either shedding load or shifting its use between different times, as well as operating

  17. Ancillary services and optimal household energy management with photovoltaic production

    This article presents a project designed to increase the monetary value of photovoltaic (PV) solar production for residential applications. To contribute to developing new functionalities for this type of PV system and an efficient control system for optimising its operation, this article explains how the proposed system could contract to provide ancillary services, particularly the supply of active power services. This provision of service by a PV-based system for domestic applications, not currently available, has prompted a market design proposal related to the distribution system. The mathematical model for calculating the system's optimal operation (sources, load and exchanges of power with the grid) results in a linear mix integer optimisation problem in which the objective is to maximise the profits achieved by taking part in the electricity market. Our approach is illustrated in a case study. PV producers could gain by taking part in the markets for balancing power or ancillary services despite the negative impact on profit of several types of uncertainty, notably the intermittent nature of the PV source.

  20. Usage of direct search methods in predictive control of ancillary services

    Most European transmission systems are interconnected to ensure the reliability and accessibility of electric power supply. Transmission system operators (TSOs) are responsible for ensuring that contracted cross-border supplies are available and that deficits are accommodated. TSOs typically buy ancillary services in advance for use in periods of deficit. This paper described a predictive control approach for ancillary services in interconnected electricity systems. The model was designed to predict the difference between contracted and actual cross-border transmission of electric power. The power sources were considered as individual power plants. The receding horizon principle was applied in order to compute the time sequences of individual sources for longer prediction periods using only the initial part of the sequences. Coverage included positive tertiary regulation; negative tertiary regulation; quickstart; dispatch reserve; and energy bought from other countries. Inputs were converted into binary values for the optimization algorithm. The technical properties of individual sources were used as fundamental constraints. The optimization algorithm was able to determine optimal sequences of ancillary services within a prediction horizon of 6 hours. 6 refs., 1 tab., 6 figs.

  1. Commercial Building Loads Providing Ancillary Services in PJM

    MacDonald, Jason; Kiliccote, Sila; Boch, Jim; Chen, Jonathan; Nawy, Robert

    2014-06-27

    The adoption of low carbon energy technologies such as variable renewable energy and electric vehicles, coupled with the efficacy of energy efficiency to reduce traditional base load has increased the uncertainty inherent in the net load shape. Handling this variability with slower, traditional resources leads to inefficient system dispatch, and in some cases may compromise reliability. Grid operators are looking to future energy technologies, such as automated demand response (DR), to provide capacity-based reliability services as the need for these services increase. While DR resources are expected to have the flexibility characteristics operators are looking for, demonstrations are necessary to build confidence in their capabilities. Additionally, building owners are uncertain of the monetary value and operational burden of providing these services. To address this, the present study demonstrates the ability of demand response resources providing two ancillary services in the PJM territory, synchronous reserve and regulation, using an OpenADR 2.0b signaling architecture. The loads under control include HVAC and lighting at a big box retail store and variable frequency fan loads. The study examines performance characteristics of the resource: the speed of response, communications latencies in the architecture, and accuracy of response. It also examines the frequency and duration of events and the value in the marketplace which can be used to examine if the opportunity is sufficient to entice building owners to participate.

  2. Effective Ancillary Services Market Designs on High Wind Power Penetration Systems: Preprint

    Ela, E.; Kirby, B.; Navid, N.; Smith, J. C.

    2011-12-01

    This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power. Ancillary services markets have been developed in many of the restructured power system regions throughout the world. Ancillary services include the services that support the provision of energy to support power system reliability. The ancillary services markets are tied tightly to the design of the energy market and to the physics of the system and therefore careful consideration of power system economics and engineering must be considered in their design. This paper focuses on how the ancillary service market designs are implemented and how they may require changes on systems with greater penetrations of variable renewable energy suppliers, in particular wind power.

  3. An assessment of market and policy barriers for demand response providing ancillary services in U.S. electricity markets

    An impact of increased variable renewable generation is the need for balancing authorities to procure more ancillary services. While demand response resources are technically capable of providing these services, current experience across the U.S. illustrates they are relatively minor players in most regions. Accessing demand response resources for ancillary services may require a number of changes to policies and common practices at multiple levels. Regional reliability councils must first define ancillary services such that demand response resources may provide them. Once the opportunity exists, balancing authorities define and promulgate rules that set the infrastructure investments and performance attributes of a resource wishing to provide such services. These rules also dictate expected revenue streams which reveal the cost effectiveness of these resources. The regulatory compact between utility and state regulators, along with other statutes and decisions by state policymakers, may impact the interest of demand response program providers to pursue these resources as ancillary service providers. This paper identifies within these broad categories specific market and policy barriers to demand response providing ancillary services in different wholesale and retail environments, with emphasis on smaller customers who must be aggregated through a program provider to meet minimum size requirements for wholesale transactions. - Highlights: • We identify barriers keeping demand response from providing ancillary services. • Institutional, financial and program provider business model barriers exist. • Product definitions and rules do not always accommodate demand response well. • Expected revenues are uncertain and may not exceed required investments costs. • Regulatory compact and state statutes limit opportunities for program providers

  4. Transactive Control and Coordination of Distributed Assets for Ancillary Services

    The need to diversify energy supplies, the need to mitigate energy-related environmental impact, and the entry of electric vehicles in large numbers present challenges and opportunities to power system professionals. Wind and solar power provide many benefits, and to reap the benefits the resulting increased variability—forecasted as well as unforecasted—should be addressed. Demand resources are receiving increasing attention as one means of providing the grid balancing services. Control and coordination of a large number (~millions) of distributed smart grid assets requires innovative approaches. One such is transactive control and coordination (TC2)—a distributed, agent-based incentive and control system. The TC2 paradigm is to create a market system with the following characteristics: • Participation should be entirely voluntary. • The participant decides at what price s/he is willing to participate. • The bids and responses are automated. Such an approach has been developed and demonstrated by Pacific Northwest National Laboratory for energy markets. It is the purpose of this project to develop a similar approach for ancillary services. In this report, the following ancillary services are considered: • spinning reserve • ramping • regulation. These services are to be provided by the following devices: • refrigerators • water heaters • clothes dryers • variable speed drives. The important results are summarized below: The regulation signal can be divided into an energy-neutral high frequency component and a low frequency component. The high frequency component is particularly well suited for demand resources. The low frequency component, which carries energy non-neutrality, can be handled by a combination of generators and demand resources. An explicit method for such a separation is obtained from an exponentially weighted moving average filter. Causal filters (i.e., filters that process only present and past values of a signal

  6. Technical and economic aspects of ancillary services markets in the electric power industry: an international comparison

    We present a comparative analysis of technical and economic aspects of ancillary services on the markets of England and Wales, Nordic Countries, California, Argentina, Australia and Spain, comparing the services of voltage control, frequency regulation and system restoration. All the analyzed markets rely on the existence of an administrator of ancillary services, function that leads to the figure of the system operator. Among the services analyzed, the mandatory nature of voltage control and primary frequency regulation stands out, being both the ancillary services with the higher market price and the shortest period of time requirements. In general, the recognized costs of the services correspond to investments operation, maintenance, and opportunity costs. In the provision of these ancillary services, there are no clear preferences for a particular resource allocation mechanism, where mandatory provision, auctions, competitive offers and different time length bilateral contracts are combined

  13. Security-constrained ancillary services allocation and pricing in integrated markets

    Ancillary services are used to control system frequency and to ensure the secure and reliable transmission of electricity from suppliers to consumers. A new dispatch formulation for determining optimal network security constraints for generator active-power schedules and the allocation of ancillary services was presented in this study. The conventional optimal power flow (OPF) formulation was based on an integrated market model with energy and ancillary services procured simultaneously using a co-optimization process. The Newton method for optimizing the Lagrange function formed from individual cost functions and constraints was used. The contingency formulation considered power demand variations at load nodes. Additional control variables were added in order to meet new load demands in the dispatch formulation. A Lagrange function was used to develop an extended set of security constraints as well as individual prices for ancillary service providers. Costs related to maintenance, lower efficiency and lower active-power generation were the variable costs of frequency control. Services compensating the transmission system losses between consumers and suppliers were described as grid loss compensation services. Case studies of representative power systems were used to verify the new dispatch calculation method. The study showed that minimizing the procurement costs of ancillary services can lead to insecure system operations. 13 refs., 3 tabs., 3 figs.

Most of the tariffs filed with FERC price these services on the basis of traditional cost-of-service (embedded) costs, Because most of these services are provided by generating units, however, it should be possible to create competitive markets for them. This paper describes, the structure of, and results from, a spreadsheet model that simulates markets for seven services: losses,...

    Johnstone, Peter A S; Hendrickson, Julie A W; Dernbach, Allison J; Secord, Ann R; Parker, John C; Favata, Michael A; Puckett, Michael L

    2003-01-01

    Within the naval medical center construct, the disparate disciplines encompassed within ancillary services lend themselves to formal quality analysis and process improvement. This analysis uses the Six Sigma approach. Error rates were investigated and calculated for various processes within ancillary services at Naval Medical Center, San Diego. These were translated into the common metric of defects per million opportunities (DPMO). DPMO rates vary between 21.5 and 420,000. These correspond to Sigma values from 1.7 to approaching 6. Rates vary with biological complexity of the system and the degree of automation available. Some ancillary services translate well into a Six Sigma schema. Systems with high potential patient risk if performed poorly and those amenable to second checking and computer oversight may be candidates for such optimization. This should be undertaken in a local environment conducive to individual error reporting, and in a corporate environment with the will and funding to support the transition. PMID:12593375

  17. Mixed integer non-linear programming and Artificial Neural Network based approach to ancillary services dispatch in competitive electricity markets

    Highlights: • Ancillary services market management. • Ancillary services requirements forecast based on Artificial Neural Network. • Ancillary services clearing mechanisms without complex bids and with complex bids. - Abstract: Ancillary services represent a good business opportunity that must be considered by market players. This paper presents a new methodology for ancillary services market dispatch. The method considers the bids submitted to the market and includes a market clearing mechanism based on deterministic optimization. An Artificial Neural Network is used for day-ahead prediction of Regulation Down, regulation-up, Spin Reserve and Non-Spin Reserve requirements. Two test cases based on California Independent System Operator data concerning dispatch of Regulation Down, Regulation Up, Spin Reserve and Non-Spin Reserve services are included in this paper to illustrate the application of the proposed method: (1) dispatch considering simple bids; (2) dispatch considering complex bids

This paper summarizes AS in China and analyzes the necessary characteristics and advantages of industrial users to provide AS according to their response mechanism. Cement manufacturing and aluminum smelter processes are selected as two representatives of responsive industrial loads. An agent-based model that includes generation, industrial user, and grid agents is proposed. Using two case studies, we analyze the integrated power management of conventional units and industrial loads in day-ahead and real-time AS scheduling based on real device parameters, price mechanisms and production data. The simulation results indicate that the participation of responsive industrial loads in the provision of AS, in China, can improve the coal consumption rate and the system-wide load factor as well as reduce the total system cost for the provision of AS significantly.

    The ECCAD database (Emissions of atmospheric Compounds and Compilation of Ancillary Data) provides a user-friendly access to global and regional surface emissions for a large set of chemical compounds and ancillary data (land use, active fires, burned areas, population,etc). The emissions inventories are time series gridded data at spatial resolution from 1x1 to 0.1x0.1 degrees. ECCAD is the emissions database of the GEIA (Global Emissions InitiAtive) project and a sub-project of the French Atmospheric Data Center AERIS (http://www.aeris-data.fr). ECCAD has currently more than 2200 users originating from more than 80 countries. The project benefits from this large international community of users to expand the number of emission datasets made available. ECCAD provides detailed metadata for each of the datasets and various tools for data visualization, for computing global and regional totals and for interactive spatial and temporal analysis. The data can be downloaded as interoperable NetCDF CF-compliant files, i.e. the data are compatible with many other client interfaces. The presentation will provide information on the datasets available within ECCAD, as well as examples of the analysis work that can be done online through the website: http://eccad.aeris-data.fr.

    With significantly increasing share of variable renewable power generation like wind and solar PV, the need in the power system for ancillary services supporting the network frequency, voltage, etc. changes. Turning this issue around, market opportunities will emerge for wind and solar PV technology to deliver such grid services. In the European power system, adequate market mechanisms need to be developed to ensure that there will be an efficient trading of these services. For that purpose a range of (economic) characteristics of wind (and solar) power as providers of grid services need to be better understood. This relates both to the technical capabilities of the plants for delivering specific services and to the quantification of the needs. The paper presents the approach of the European lEE project REserviceS, aiming at establishing reference guidance for the ongoing developments in Europe of network codes and electricity market design. Economic insights gained from REserviceS will be shaped into recommendations to be used when establishing electricity market mechanisms and Network Codes at EU level. The project approach presented in the paper consists of two main parts namely (1) conceptually analyzing system needs for ancillary services and at assessing the technical aspects of and cost of delivering these services by solar PV and wind power, in scenarios of high renewable penetration. (2) Investigation of the need for ancillary services in typical transmission and distribution networks, and the cost and options to deliver these services at high penetration. The paper will give an overview of case studies envisaged, together with the intended methods used for the analysis. The paper also gives some initial project results. It presents the outcome of the assessment of ancillary services that are especially relevant for wind and solar power. These are mainly related to frequency, voltage control and restoration of the system. In addition, based on existing

  5. VOLTTRON-Based System for Providing Ancillary Services with Residential Building Loads

    Jin, Xin

    2016-07-01

    Ancillary services entail controlled modulation of building equipment to maintain a stable balance of generation and load in the power system. Ancillary services include frequency regulation and contingency reserves, whose acting time ranges from several seconds to several minutes. Many pilot studies have been implemented to use industrial loads to provide ancillary services, and some have explored services from commercial building loads or electric vehicle charging loads. Residential loads, such as space conditioning and water heating, represent a largely untapped resource for providing ancillary services. The residential building sector accounts for a significant fraction of the total electricity use in the United States. Many loads in residential buildings are flexible and could potentially be curtailed or shifted at the request of the grid. However, there are many barriers that prevent residential loads being widely used for ancillary services. One of the major technical barriers is the lack of communication capabilities between end-use devices and the grid. End-use devices need to be able to receive the automatic generation control (AGC) signal from the grid operator and supply certain types of telemetry to verify response. With the advance of consumer electronics, communication-enabled, or 'connected,' residential equipment has emerged to overcome the communication barrier. However, these end-use devices have introduced a new interoperability challenge due to the existence of numerous standards and communication protocols among different end devices. In this paper, we present a VOLTTRON-based system that overcomes these technical challenges and provides ancillary services with residential loads. VOLTTRON is an open-source control and sensing platform for building energy management, facilitating interoperability solutions for end devices. We have developed drivers to communicate and control different types of end devices through standard

  6. Alternative Approaches for Incentivizing the Frequency Responsive Reserve Ancillary Service

    Ela, E.; Milligan, M.; Kirby, B.; Tuohy, A.; Brooks, D.

    2012-03-01

    Frequency responsive reserve is the autonomous response of generators and demand response to deviations of system frequency, usually as a result of the instantaneous outage of a large supplier. Frequency responsive reserve arrests the frequency decline resulting in the stabilization of system frequency, and avoids the triggering of under-frequency load-shedding or the reaching of unstable frequencies that could ultimately lead to system blackouts. It is a crucial service required to maintain a reliable and secure power system. Regions with restructured electricity markets have historically had a lack of incentives for frequency responsive reserve because generators inherently provided the response and on large interconnected systems, more than sufficient response has been available. This may not be the case in future systems due to new technologies and declining response. This paper discusses the issues that can occur without proper incentives and even disincentives, and proposes alternatives to introduce incentives for resources to provide frequency responsive reserve to ensure an efficient and reliable power system.

    This study provides an examination of various market and policy barriers to demand response providing ancillary services in both ISO/RTO and non-ISO/RTO regions, especially at the program provider level. It is useful to classify barriers in order to create a holistic understanding and identify parties that could be responsible for their removal. This study develops a typology of barriers focusing on smaller customers that must rely on a program provider (i.e., electric investor owned utility or IOU, ARC) to create an aggregated DR resource in order to bring ancillary services to the balancing authority. The barriers were identified through examinations of regulatory structures, market environments, and product offerings; and discussions with industry stakeholders and regulators. In order to help illustrate the differences in barriers among various wholesale market designs and their constituent retail environments, four regions were chosen to use as case studies: Colorado, Texas, Wisconsin, and New Jersey.

  10. Identifying children in need of ancillary and enabling services: a population approach.

    Benedict, Ruth E; Farel, Anita M

    2003-12-01

    Children with chronic or disabling conditions use health, education and social services at a higher rate than their healthy peers. Estimates of the number of children in need of these specialized services are widely varied and often depend on categorical definitions that do not account for either the diversity or commonality of their experiences. Developing methods for identifying the population in need of services, particularly children likely to use long-term ancillary (audiology, occupational, physical or speech therapy, or social work) and/or enabling services (special equipment, personal care assistance, respite care, transportation, or environmental modifications), is essential for effective policy and program implementation. This study examines several recent attempts to operationalize definitions of children with chronic conditions using a noncategorical classification approach. Particular emphasis is placed on the subgroup of children identified as having functional limitations. Proposed operational definitions of children with functional limitations are compared using data from the 1994-1995 Disability Supplement to the US National Health Interview Survey. Estimates of the number of children reported to be using ancillary and enabling services are generated and compared across operational definitions of functional limitation as well as by the number, severity, and type (i.e. mobility, self-care, communication/sensory, social cognition/learning ability) of limitation. Depending on the operational definition selected, 9-14% of US community-dwelling children are estimated to have functional limitations. Among children with limitations, 26-30% regularly use ancillary services and 11-14% use enabling services. The strengths, limitations, and potential applications for each operational definition are discussed. PMID:14512235

  13. Resource and revenue potential of California residential load participation in ancillary services

    Increasing penetrations of intermittent renewable energy resources will require additional power system services. California recently adopted an energy storage mandate to support its renewable portfolio standard, which requires 33% of delivered energy from renewables by 2020. The objective of this paper is to estimate the amount of energy storage that could be provided by residential thermostatically controlled loads, such as refrigerators and air conditioners, and the amount of revenue that could be earned by loads participating in ancillary services markets. We model load aggregations as virtual energy storage, and use simple dynamical system models and publicly available data to generate our resource and revenue estimates. We find that the resource potential is large: 10–40 GW/8–12 GWh, which is significantly more than that required by the mandate. We also find that regulation and spinning/non-spinning reserve revenues vary significantly depending upon type of load and, for heat pumps and air conditioners, climate zone. For example, mean regulation revenues for refrigerators are $11/year, for electric water heaters are $24/year, for air conditioners are $0-32/year, and for heat pumps are $22–56/year. Both consumer choices, such as appliance settings, and policy, such as the design of ancillary service compensation and appliance standards, could increase revenue potentials. - Highlights: • California's energy storage mandate requires 1.325 GW of energy storage by 2020. • Residential loads such as refrigerators have thermal energy storage. • California's residential loads could provide 10-40 GW/8-12 GWh of storage. • Loads participating in ancillary services markets could earn up to $56/load/year. • Consumer choices and policy mechanisms could increase revenue potentials

  16. An integrated pan-European ancillary services market for frequency control

    Real-time balancing of mismatches between consumption and production is one of the key elements for the secure operation of power systems. This takes place within the framework of ancillary services managed by respective national transmission system operating companies. The objective of this paper is to investigate the option of one integrated pan-European ancillary services market. Our contribution is twofold: quantifying the potential benefit of such an option and outlining a possible approach to such an option highlighting its positive properties as well as risks and challenges. In several recently published considerations of pan-European electricity supply models this topic has not been adequately addressed, but we believe it is one of the crucial subjects in shaping the future electricity supply in Europe. -- Author-Highlights: •We investigated the option of a one-area market for frequency control in Continental Europe. •For the current situation a centralised approach may lead to a significant reduction of control reserves. •In the long run it is a possibility to avoid a tremendous increase of needed control reserves. •The implementation of an integrated market is not to be underestimated

    The Pacific Gas and Electric Company (PG&E) is conducting a pilot program to investigate the technical feasibility of bidding certain demand response (DR) resources into the California Independent System Operator's (CAISO) day-ahead market for ancillary services nonspinning reserve. Three facilities, a retail store, a local government office building, and a bakery, are recruited into the pilot program. For each facility, hourly demand, and load curtailment potential are forecasted two days ahead and submitted to the CAISO the day before the operation as an available resource. These DR resources are optimized against all other generation resources in the CAISO ancillary service. Each facility is equipped with four-second real time telemetry equipment to ensure resource accountability and visibility to CAISO operators. When CAISO requests DR resources, PG&E's OpenADR (Open Automated DR) communications infrastructure is utilized to deliver DR signals to the facilities energy management and control systems (EMCS). The pre-programmed DR strategies are triggered without a human in the loop. This paper describes the automated system architecture and the flow of information to trigger and monitor the performance of the DR events. We outline the DR strategies at each of the participating facilities. At one site a real time electric measurement feedback loop is implemented to assure the delivery of CAISO dispatched demand reductions. Finally, we present results from each of the facilities and discuss findings.

  18. Development of modified rational buyer auction for procurement of ancillary services utilizing participation matrix

    The rational buyer auction is based on a simultaneous auction that is the redesigned auction mechanism for ancillary services by the California independent system operator (CAISO). The incentive for the rational buyer auction is CAISO's intent to adopt a common sense rule of substituting higher-quality lower-cost services for lower-quality higher-cost services, when it results in reduced total procurement cost. For the purposes of designing a desirable auction where the minimum cost for the objective function as well as prevention of price reversal are achieved, either the payment cost in marginal pricing auction must be lowered or price reversal in rational buyer auction must be avoided. The objectives of this study are (a) to develop a newly proposed 'modified rational buyer' auction that does not allow price reversal and (b) to propose and validate a solution procedure that is based on participation matrix and discrete programming. The validation of the proposed solution procedure is accomplished through examination of two case studies available in the literature. Based on the first case study data, it is shown that the newly developed modified rational buyer auction avoids price reversal occurrence, while the total payment of ISO is increased by 5.8%, as compared with rational buyer auction. Also in comparison with marginal pricing auction, the ISO payment is lowered by 38.8%, when the newly developed modified rational buyer auction is utilized. For future work, it is recommended that the application of the modified rational buyer auction to joint dispatch of energy and ancillary services is investigated. (author)

  19. Electric industry restructuring, ancillary services, and the potential impact on wind

    1997-12-31

    The new competitive electric power environment raises increased challenges for wind power. The DOE and EPRI wind programs have dealt extensively with the traditional vertically integrated utility planning and operating environment in which the host utility owns the generation (or purchases the power) and provides dispatch and transmission services. Under this traditional environment, 1794 MW of wind power, principally in California, have been successfully integrated into the U.S. electric power system. Another 4200 MW are installed elsewhere in the world. As issues have arisen, such as intermittency and voltage regulation, they have been successfully addressed with accepted power system procedures and practices. For an intermittent, non-dispatchable resource such as wind, new regulatory rules affecting power transmission services, raise questions about which ancillary services wind plants will be able to sell, which they will be required to purchase, and what the economic impacts will be on individual wind projects. This paper begins to look at issues of concern to wind in a restructured electric industry. The paper first briefly looks at the range of unbundled services and comments on their unique significance to wind. To illustrate the concerns that arise with restructuring, the paper then takes a more detailed look at a single service: regulation. Finally, the paper takes a brief look at technologies and strategies that could improve the competitive position of wind.

  2. Cost-Causation-Based Tariffs for Wind Ancillary Service Impacts: Preprint

    Kirby, B.; Milligan, M.; Wan, Y.

    2006-06-01

    Conference paper discussing the integration cost of wind. Although specific tariffs for wind generation for ancillary services are uncommon, we anticipate that balancing authorities (control areas) and other entities will move toward such tariffs. Tariffs for regulation and imbalance services should be cost-based, recognize the relevant time scales that correspond with utility operational cycles, and properly allocate those costs to those entities that cause the balancing authority to incur the costs. In this paper, we present methods for separating wind's impact into regulation and load following (imbalance) time scales. We show that approximating these impacts with simpler methods can significantly distort cost causation and even cause confusion between the relevant time scales. We present results from NREL's wind data collection program to illustrate the dangers of linearly scaling wind resource data from small wind plants to approximate the wind resource data from large wind plants. Finally, we provide a framework for developing regulation and imbalance tariffs, we outline methods to begin examining contingency reserve requirements for wind plants, we provide guidance on the important characteristics to consider, and we provide hypothetical cases that the tariff can be tested against to determine whether the results are desired.

  3. Accessibility of adolescent health services

    S Richter

    2000-09-01

    Full Text Available Adolescents represent a large proportion of the population. As they mature and become sexually active, they face more serious health risks. Most face these risks with too little factual information, too little guidance about sexual responsibility and multiple barriers to accessing health care. A typical descriptive and explanatory design was used to determine what the characteristics of an accessible adolescent health service should be. Important results and conclusions that were reached indicate that the adolescent want a medical doctor and a registered nurse to be part of the health team treating them and they want to be served in the language of their choice. Family planning, treatment of sexually transmitted diseases and psychiatric services for the prevention of suicide are services that should be included in an adolescent accessible health service. The provision of health education concerning sexual transmitted diseases and AIDS is a necessity. The service should be available thought out the week (included Saturdays and within easy reach. It is recommended that minor changes in existing services be made, that will contribute towards making a health delivery service an adolescent accessible service. An adolescent accessible health service can in turn make a real contribution to the community’s efforts to improve the health of its adolescents and can prove to be a rewarding professional experience to the health worker.

  5. Analysis of the Effects of a Flexible Ramping Ancillary Service Product on Power System Operations: Preprint

    Krad, Ibrahim; Ibanez, Eduardo; Ela, Erik

    2015-10-19

    The recent increased interest in utilizing variable generation (VG) resources such as wind and solar in power systems has motivated investigations into new operating procedures. Although these resources provide desirable value to a system (e.g., no fuel costs or emissions), interconnecting them provides unique challenges. Their variable, non-controllable nature in particular requires significant attention, because it directly results in increased power system variability and uncertainty. One way to handle this is via new operating reserve schemes. Operating reserves provide upward and downward generation and ramping capacity to counteract uncertainty and variability prior to their realization. For instance, uncertainty and variability in real-time dispatch can be accounted for in the hour-ahead unit commitment. New operating reserve methodologies that specifically account for the increased variability and uncertainty caused by VG are currently being investigated and developed by academia and industry. This paper examines one method inspired by the new operating reserve product being proposed by the California Independent System Operator. The method is based on examining the potential ramping requirements at any given time and enforcing those requirements via a reserve demand curve in the market-clearing optimization as an additional ancillary service product.

  6. Impact of Production from Photovoltaic Power Plants on Increase of Ancillary Services in the Czech Republic

    Martin Smocek

    2016-01-01

    Full Text Available Renewable energy resources represent a noticeable part of the overall energetic concept development. New integration of renewable energy resources into power grids has a significant impact on the reliability and quality of power supply. The major problem of the photovoltaic and wind power plants is their dependency on weather conditions, since it has a direct effect on their immediate output produced that shows stochastic behaviour. These stochastic outputs result in very adverse impacts on the power grid. Further development of these resources could lead to exceeding of the control and absorption abilities of the power grid. The power grid must be set in balance with respect to the production and consumption of electric power at any time. The operation of photovoltaic power plants impair keeping this balance. That has an adverse impact on the very operation and maintenance of network parameters within the extent required. This survey deals with analysis focused on operation of the photovoltaic power plants with respect to the increase of reserve power in ancillary services in the Czech Republic.

    The German government aims at a share of electricity generation based on renewable sources (RES-E) of more than 30% by 2020. A major part of this share will be reached by the use of wind power plants (WPP). Therefore, when amending the Renewable Energy Sources Act (EEG) in June 2008, the German government acknowledged the importance of enhanced technical requirements for WPP and announced the development of a respective technical ordinance. For all WPP that go into operation after June 2010, full grid code-compliance becomes a precondition for privileged network access, receipt of feed-in tariff, and extra payments (''ancillary services bonus''). The basis for the technical requirements in the EEG has been laid down by Medium-Voltage (MV)-Directive 2008 and the TransmissionCode 2007. However, the work of the authors - consulting the German government during the development of the technical ordinance - showed that the TransmissionCode 2007 needed careful review and some clarifying specifications were proposed. Eventually, the so called ''Ancillary Services Ordinance'' for wind power plants went into power in July 2009. The interrelation between all three grid codes as well as their specifications and implications for renewable energy sources generators, with special regard to wind power plants, are presented in this paper.

    Revenue insufficiency, or the missing money problem, occurs when the revenues that generators earn from the market are not sufficient to cover both fixed and variable costs to remain in the market and/or justify investments in new capacity, which may be needed for reliability. The near-zero marginal cost of variable renewable generators further exacerbates these revenue challenges. Estimating the extent of the missing money problem in current electricity markets is an important, nontrivial task that requires representing both how the power system operates and how market participants behave. This paper explores the missing money problem using a production cost model that represented a simplified version of the Electric Reliability Council of Texas (ERCOT) energy-only market for the years 2012-2014. We evaluate how various market structures -- including market behavior, ancillary services, and changing fleet compositions -- affect net revenues in this ERCOT-like system. In most production cost modeling exercises, resources are assumed to offer their marginal capabilities at marginal costs. Although this assumption is reasonable for feasibility studies and long-term planning, it does not adequately consider the market behaviors that impact revenue sufficiency. In this work, we simulate a limited set of market participant strategic bidding behaviors by means of different sets of markups; these markups are applied to the true production costs of all gas generators, which are the most prominent generators in ERCOT. Results show that markups can help generators increase their net revenues overall, although net revenues may increase or decrease depending on the technology and the year under study. Results also confirm that conventional, variable-cost-based production cost simulations do not capture prices accurately, and this particular feature calls for proxies for strategic behaviors (e.g., markups) and more accurate representations of how electricity markets work.

  10. Secure provision of reactive power ancillary services in competitive electricity markets

    El-Samahy, Ismael

    decoupled and assumed to be fixed during the reactive power dispatch procedures; however, the effect of reactive power on real power is considered in the model by calculating the required reduction in real power output of a generator due to an increase in its reactive power supply. In this case, real power generation is allowed to be rescheduled, within given limits, from the already dispatched levels obtained from the energy market clearing process. The proposed dispatch model achieves the main objective of an ISO in a competitive electricity market, which is to provide the required reactive power support from generators at least cost while ensuring a secure operation of the power system. The proposed reactive power procurement and dispatch models capture both the technical and economic aspects of power system operation in competitive electricity markets; however, from an optimization point of view, these models represent non-convex mixed integer non-linear programming (MINLP) problems due to the presence of binary variables associated with the different regions of reactive power operation in a synchronous generator. Such MINLP optimization problems are difficult to solve, especially for an actual power system. A novel Generator Reactive Power Classification (GRPC) algorithm is proposed in this thesis to address this issue, with the advantage of iteratively solving the optimization models as a series of non-linear programming (NLP) sub-problems. The proposed reactive power procurement and dispatch models are implemented and tested on the CIGRE 32-bus system, with several case studies that represent different practical operating scenarios. The developed models are also compared with other approaches for reactive power provision, and the results demonstrate the robustness and effectiveness of the proposed model. The results clearly reveal the main features of the proposed models for optimal provision of reactive power ancillary service, in order to suit the requirements of

  11. From a bundled energy-capacity pricing model to an energy-capacity-ancillary services pricing model

    In this paper, we extend the Chilean power generation pricing mechanism, with capacity and energy payments, to one where ancillary services (AS), as frequency regulation and voltage control, are explicitly recognized. Adequacy and security attributes of the electric system and the public good characteristics of AS are set within the payment structure to distribute the financing of AS among those who benefit from their provision. The contribution to finance the provision of AS is determined assessing the value assigned to the system security by each agent, following what's an efficient pricing mechanism in the presence of public goods

  12. Active Power Control of Wind Turbines for Ancillary Services: A Comparison of Pitch and Torque Control Methodologies

    Aho, Jacob; Fleming, Paul; Pao, Lucy Y.

    2016-08-01

    As wind energy generation becomes more prevalent in some regions, there is increased demand for wind power plants to provide ancillary services, which are essential for grid reliability. This paper compares two different wind turbine control methodologies to provide active power control (APC) ancillary services, which include derating or curtailing power generation, providing automatic generation control (AGC), and providing primary frequency control (PFC). The torque APC controller provides all power control through the power electronics whereas the pitch APC controller uses the blade pitch actuators as the primary means of power control. These controllers are simulated under various wind conditions with different derating set points and AGC participation levels. The metrics used to compare their performance are the damage equivalent loads (DELs) induced on the structural components and AGC performance metrics, which are used to determine the payments for AGC services by system operators in the United States. The simulation results show that derating the turbine reduces structural loads for both control methods, with the APC pitch control providing larger reductions in DELs, lower AGC performance scores, and higher root-mean-square pitch rates. Providing AGC increases the structural loads when compared to only derating the turbine, but even the AGC DELs are generally lower than those of the baseline control system. The torque APC control methodology also allows for more sustained PFC responses under certain derating conditions.

  13. A framework for cost-based pricing of transmission and ancillary services in competitive electric power markets

    In this paper the authors propose a framework for accurate cost determination and pricing of transmission and ancillary services in competitive electric power markets. The proposed framework is based on their anticipation of the evolving environment and industry structure. They envision the future as a competitive energy market with a centralized control entity that coordinates system activities, prices transmission and ancillary services and controls various system resources. This control entity has control over a certain (pre-defined) geographical area. It is proposed that the system operation and control be kept as they are currently done in control centers, no major change in these functions is required for the proposed pricing strategy. The pricing strategy is divided into two main classes based on time scale separation and firmness, short and long term, firm and interruptible contracts. The approach is based on superposition of different transaction on the network, and a three-part tariff design. The charges are directly related to the impact of each transaction on the system

  14. Three utilization patterns of the renovated Moste hydro power plant on an electricity market of power and ancillary services

    In addition to electricity, most hydro power plants can offer also the ancillary services: secondary and tertiary control reserve. On emerging electricity markets the need for these additional services is becoming more and more important, recognised and also paid. However, for each plant, there is some interdependence among those options. The same plant cannot provide maximal peaking electricity, maximal secondary control reserve as well as maximal tertiary control reserve at the same time. The generation capabilities of the plant must thus be partitioned properly among those options so as to achieve some overall goal (e.g. the maximum of revenue, etc.). This article briefly presents those options for the renovated Moste cascade on the upper Sava river near Bled in Slovenia. A small but effective mixed integer linear programme has been used.

  15. The business of medicine: how to overcome financial obstacles and secure financing for your private practice and ancillary services business.

    Nayor, David

    2012-01-01

    Doctors across the country who operate private medical practices are facing increasing financial obstacles, namely shrinking income as a result of rising costs and lower reimbursements. In addition, as hospitals have become overburdened many physicians have opened up private surgical centers; magnetic resonance imaging and computed tomography and positron emission tomography scanning facilities; pathology labs; colonoscopy/endoscopy suites; lithotripsy centers; and other medical businesses typically performed within the hospital. Moreover, many doctors seek loans to purchase existing practices or for their capital contribution in medical partnerships. The past decade has thus seen a significant increase in the number of doctors taking out small business loans. Indeed, banks view the healthcare industry as a large growth market. This article includes practical information, advice, and resources to help doctors to secure bank financing for their practices, ancillary services business, real estate, and equipment on the best possible market terms.

  8. Smart microgrid hierarchical frequency control ancillary service provision based on virtual inertia concept: An integrated demand response and droop controlled distributed generation framework

    Highlights: • Detailed formulation of the microgrid static and dynamic securities based on droop control and virtual inertia concepts. • Constructing a novel objective function using frequency excursion and rate of change of frequency profiles. • Ensuring the microgrid security subject to the microgrid economic and environmental policies. • Coordinated management of demand response and droop controlled distributed generation resources. • Precise scheduling of day-ahead hierarchical frequency control ancillary services using a scenario based stochastic programming. - Abstract: Low inertia stack, high penetration levels of renewable energy source and great ratio of power deviations in a small power delivery system put microgrid frequency at risk of instability. On the basis of the close coupling between the microgrid frequency and system security requirements, procurement of adequate ancillary services from cost-effective and environmental friendly resources is a great challenge requests an efficient energy management system. Motivated by this need, this paper presents a novel energy management system that is aimed to coordinately manage the demand response and distributed generation resources. The proposed approach is carried out by constructing a hierarchical frequency control structure in which the frequency dependent control functions of the microgrid components are modeled comprehensively. On the basis of the derived modeling, both the static and dynamic frequency securities of an islanded microgrid are provided in primary and secondary control levels. Besides, to cope with the low inertia stack of islanded microgrids, novel virtual inertia concept is devised based on the precise modeling of droop controlled distributed generation resources. The proposed approach is applied to typical test microgrid. Energy and hierarchical reserve resource are scheduled precisely using a scenario-based stochastic programming methodology. Moreover, analyzing the

    2006-06-01

    The European Southern Observatory (ESO) is in the process of creating a central access point for all services offered to its user community via the Web. That gateway, called the User Portal, will provide registered users with a personalized set of service access points, the actual set depending on each user's privileges. Correspondence between users and ESO will take place by way of "profiles", that is, contact information. Each user may have several active profiles, so that an investigator may choose, for instance, whether their data should be delivered to their own address or to a collaborator. To application developers, the portal will offer authentication and authorization services, either via database queries or an LDAP server. The User Portal is being developed as a Web application using Java-based technology, including servlets and JSPs.

  11. Improving service accessibility in service-oriented HIS.

    Babamir, Seyed Morteza; Arabfard, Masoud

    2012-12-01

    Nowadays, new trend in design and implementation of Hospital Information System (HIS) is towards using Web-based Service-Oriented Architecture (SOA). However, the standard SOA includes an insensitive service store through which the accessibility of some hospital services becomes difficult when their specification or network address are changed or missed. This paper discusses problems of insensitive service store and then presents a model where a sensitive service store is used to mitigate the problems. To show the efficiency of the proposed model, HIS of the Shahid Beheshti Hospital of Kashan including information systems of Admission, Outpatient, Ward, Pharmacy, Medical Document, Discharge and Insurance was designed and implemented with sensitive service store and its performance was considered.

  18. NASA Alternate Access to Station Service Concept

    Bailey, M. D.; Crumbly, C.

    2002-01-01

    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

  6. Health services accessibility among Spanish elderly.

    Fernández-Mayoralas, G; Rodríguez, V; Rojo, F

    2000-01-01

    The paper aims to identify the variables that best explain the use of health services by people aged 65 and over in Spain. The data comes from the 1993 Spanish National Health Survey (ENSE 93). The conceptual framework is the model proposed by Andersen, who suggests that utilisation is a function of predisposition to use the services, the ability to use them and of need. A bivariate and multivariate analysis (SPSS-X Discriminant Procedure) is conducted to define the predictors that best discriminate users and non-users. The use of each health service is explained by a different set of variables. The need variables play a more important role in predicting the use of non-discretionary services that are more closely related to healing processes (medical consultations, emergencies and hospitalisation). The predisposing and enabling variables are more relevant in explaining the use of dental services, indicating a certain degree of inequity of these discretionary services. PMID:10622691

    2011-06-01

    Full Text Available Abstract Background Many bioinformatics algorithms and data sets are deployed using web services so that the results can be explored via the Internet and easily integrated into other tools and services. These services often include data from other sites that is accessed either dynamically or through file downloads. Developers of these services face several problems because of the dynamic nature of the information from the upstream services. Many publicly available repositories of bioinformatics data frequently update their information. When such an update occurs, the developers of the downstream service may also need to update. For file downloads, this process is typically performed manually followed by web service restart. Requests for information obtained by dynamic access of upstream sources is sometimes subject to rate restrictions. Findings SideCache provides a framework for deploying web services that integrate information extracted from other databases and from web sources that are periodically updated. This situation occurs frequently in biotechnology where new information is being continuously generated and the latest information is important. SideCache provides several types of services including proxy access and rate control, local caching, and automatic web service updating. Conclusions We have used the SideCache framework to automate the deployment and updating of a number of bioinformatics web services and tools that extract information from remote primary sources such as NCBI, NCIBI, and Ensembl. The SideCache framework also has been used to share research results through the use of a SideCache derived web service.

  13. Making Spatial Statistics Service Accessible On Cloud Platform

    Mu, X.; Wu, J.; Li, T.; Zhong, Y.; Gao, X.

    2014-04-01

    Web service can bring together applications running on diverse platforms, users can access and share various data, information and models more effectively and conveniently from certain web service platform. Cloud computing emerges as a paradigm of Internet computing in which dynamical, scalable and often virtualized resources are provided as services. With the rampant growth of massive data and restriction of net, traditional web services platforms have some prominent problems existing in development such as calculation efficiency, maintenance cost and data security. In this paper, we offer a spatial statistics service based on Microsoft cloud. An experiment was carried out to evaluate the availability and efficiency of this service. The results show that this spatial statistics service is accessible for the public conveniently with high processing efficiency.

  14. Unifying Access to National Hydrologic Data Repositories via Web Services

    Valentine, D. W.; Jennings, B.; Zaslavsky, I.; Maidment, D. R.

    2006-12-01

    The CUAHSI hydrologic information system (HIS) is designed to be a live, multiscale web portal system for accessing, querying, visualizing, and publishing distributed hydrologic observation data and models for any location or region in the United States. The HIS design follows the principles of open service oriented architecture, i.e. system components are represented as web services with well defined standard service APIs. WaterOneFlow web services are the main component of the design. The currently available services have been completely re-written compared to the previous version, and provide programmatic access to USGS NWIS. (steam flow, groundwater and water quality repositories), DAYMET daily observations, NASA MODIS, and Unidata NAM streams, with several additional web service wrappers being added (EPA STORET, NCDC and others.). Different repositories of hydrologic data use different vocabularies, and support different types of query access. Resolving semantic and structural heterogeneities across different hydrologic observation archives and distilling a generic set of service signatures is one of the main scalability challenges in this project, and a requirement in our web service design. To accomplish the uniformity of the web services API, data repositories are modeled following the CUAHSI Observation Data Model.

  15. 3PAC: Enforcing Access Policies for Web Services

    Bemmel, van J.; Wegdam, M.; Lagerberg, K.

    2005-01-01

    Web services fail to deliver on the promise of ubiquitous deployment and seamless interoperability due to the lack of a uniform, standards-based approach to all aspects of security. In particular, the enforcement of access policies in a service oriented architecture is not addressed adequately. We p

  16. Secure Access to Private Services in Intranet for Mobile Clients

    2013-02-01

    Full Text Available With wide adoption of Service Computing and Mobile Computing, people tend to invoke services with mobile devices, requiring accurate and real-time feedback from services at any time and any place. Among these services, some are private to limited users and require identity authorization before use; hence secure access control in wireless network should be provided. To address the challenge, in this study, we propose the architecture and protocols of a system of access to private services for mobile clients, which combines the technologies of trusted computing, Diffie-Hellman key agreement protocol, digital certificate, DES data encryption algorithm and twice verification. We further show the implementation of the proposed system, in which we have realized the authentication and authorization of mobile clients and then secure data transfer between mobile clients in the unsafe Internet and private services in the Intranet.

  17. The Critical Role of Institutional Services in Open Access Advocacy

    Tomasz Neugebauer

    2013-06-01

    Full Text Available This paper examines the development of the Open Access movement in scholarly communication, with particular attention to some of the rhetorical strategies and policy mechanisms used to promote it to scholars and scientists. Despite the majority of journal publishers’ acceptance of author self-archiving practices, and the minimal time commitment required by authors to successfully self-archive their work in disciplinary or institutional repositories, the majority of authors still by and large avoid participation. The paper reviews the strategies and arguments used for increasing author participation in open access, including the role of open access mandates. We recommend a service-oriented approach towards increasing participation in open access, rather than rhetoric that speculates on the benefits that open access will have on text/data mining innovation. In advocating for open access participation, we recommend focusing on its most universal and tangible purpose: increasing public open (gratis access to the published results of publicly funded research. Researchers require strong institutional support to understand the copyright climate of open access self-archiving, user-friendly interfaces and useful metrics, such as repository usage statistics. We recommend that mandates and well-crafted and responsive author support services at universities will ultimately be required to ensure the growth of open access. We describe the mediated deposit service that was developed to support author self-archiving in Spectrum: Concordia University Research Repository. By comparing the number of deposits of non-thesis materials (e.g. articles and conference presentations that were accomplished through the staff-mediated deposit service to the number of deposits that were author-initiated, we demonstrate the relative significance of this service to the growth of the repository.

    Full Text Available Abstract Background Still picture transmission was performed using a telemedicine system in an Emergency Medical Service (EMS during a prospective, controlled trial. In this ancillary, retrospective study the quality and content of the transmitted pictures and the possible influences of this application on prehospital time requirements were investigated. Methods A digital camera was used with a telemedicine system enabling encrypted audio and data transmission between an ambulance and a remotely located physician. By default, images were compressed (jpeg, 640 x 480 pixels. On occasion, this compression was deactivated (3648 x 2736 pixels. Two independent investigators assessed all transmitted pictures according to predefined criteria. In cases of different ratings, a third investigator had final decision competence. Patient characteristics and time intervals were extracted from the EMS protocol sheets and dispatch centre reports. Results Overall 314 pictures (mean 2.77 ± 2.42 pictures/mission were transmitted during 113 missions (group 1. Pictures were not taken for 151 missions (group 2. Regarding picture quality, the content of 240 (76.4% pictures was clearly identifiable; 45 (14.3% pictures were considered “limited quality” and 29 (9.2% pictures were deemed “not useful” due to not/hardly identifiable content.

    Kefayati, Mahdi; Baldick, Ross

    2014-01-01

    Flexible loads, i.e. the loads whose power trajectory is not bound to a specific one, constitute a sizable portion of current and future electric demand. This flexibility can be used to improve the performance of the grid, should the right incentives be in place. In this paper, we consider the optimal decision making problem faced by a flexible load, demanding a certain amount of energy over its availability period, subject to rate constraints. The load is also capable of providing Ancillary ...

    ABSTRACT:The characteristics of demand side resources, such as fast response and low cost, are very helpful to improve wind power penetration when they are utilized to provide ancillary services for the power system. Typically, industrial demand response resources have the advantages of large capacity, load stability and are easy to manage when they are compared with commerce and inhabitant users. As a result, industrial demand response resources are very suitable to deal with large-scale wind power integration. In order to have an in-depth study on the response mechanism of industrial loads to provide ancillary services, this paper chosen electrolytic aluminum and irrigation pumping station as two typical industrial power users and analyzed the ancillary services type which could be provided. Then, a multi-agent response modeling containing these two kinds of industrial loads and the grid was built based on multi-agent technology. The goal, structure and behavior strategies of each agent were explained in the paper. In the process of simulation, the grid companies could adjust the ancillary services price according to the response of industrial power consumers. The results show that the pricing strategy of ancillary services in this model can fully exploit the response potential of all types of industrial power users to provide ancillary services while satisfying their interests.%挖掘响应迅速且成本较低的需求侧资源为电力系统提供辅助服务,对促进风电消纳具有积极意义。工业需求响应资源与商业、居民等用户相比具有容量大、负荷稳定、易于管理等优势,在应对大规模风电接入等方面具有更明显的优势。为深入研究工业用户提供辅助服务的响应机理,在分析电解铝、灌溉泵站2类典型工业负荷提供辅助服务类型的基础上,基于多智能体技术,构建了包含电网及以上2类工业负荷的多智能体系统,阐述各类智能体的目标

  2. NASA's Eos ClearingHOuse: Integrating Access to Data Services

    Burnett, M. T.; Pfister, R.; Wichman, K.

    2002-12-01

    ECHO (The Earth Observing System (EOS) ClearingHOuse) is being developed to provide flexibility to NASA's EOS to better meet the needs of the science community. ECHO is a clearinghouse of metadata, representing the data offerings of participating data providers. ECHO is being built with the goal of being an enabling system: Enabling a variety of Data Providers to participate. Enabling access to an ever-changing variety of Earth Science Data. Enabling access to an ever-growing suite of services, provided by the Science Community, which improves the usefulness of this data, including the binding of those services to the data represented in the clearinghouse. The purpose of this enabling philosophy is to support current Science efforts, but also to give the opportunity for creative organizations and individuals to break the traditional paradigm for discovering and leveraging Earth Science Data and Services in completely new ways. This presentation will focus on ECHO's approach to integrating Data Services from varied Service Providers, and facilitating access to those services by the user community. ECHO can be viewed as a typical Service oriented architecture. The fundamental interactions that it supports are (abstractly) Publish, Find and Bind. ECHO provides interfaces and mechanisms that allow organizations to publish their services. Using these interfaces, Service Providers can effectively "plug-in" their capabilities. There are mechanisms that allow the correlation of their service to the data types in the clearinghouse. ECHO's user community can find, or discover, services through a separate set of interfaces. Bindings are the mechanisms that support the invocation of services by ECHO's user community. ECHO supports binding either directly between the user and the service provider, or indirectly by using ECHO as a Service Broker. ECHO is supporting all of these Service capabilities by leveraging the contemporary (and evolving) "standards" of Web Services. Web

    A randomized controlled trial of outpatient open-access physiotherapy was carried out at West Cornwall Hospital during 1979/80. The referral rate to consultant outpatient clinics for those patients offered open-access physiotherapy was considerably lower than for the control group (17 per cent and 56 per cent respectively). Patients using the service received physiotherapy promptly although this did not result in shorter treatments. Those of the control group who eventually received physiothe...

  4. A Service Access Security Control Model in Cyberspace

    Qianmu, Li; Jie, Yin; Jun, Hou; Jian, Xu; Hong, Zhang; Yong, Qi

    A service access control model in cyberspace is proposed, which provides a generalized and effective mechanism of security management with some items constraint specifications. These constraint specifications are organized to form a construction, and an enact process is proposed to make it scalable and flexible to meet the need of diversified service application systems in cyberspace. The model of this paper erases the downward information flow by extended rules of read/write, which is the breakthrough of the limitations when applying the standard role-based access control in cyberspace.

  8. Richmond Wellbeing Service Access Strategy for Older Adults

    Gowling, Sarah; Persson, Jennie; Holt, Genevieve; Ashbourne, Sue; Bloomfield, James; Shortland, Hannah; Bate, Clare

    2016-01-01

    IAPT (Improving Access to Psychological Therapies) is a national programme aimed at increasing availability of evidence based psychological therapies in the NHS. IAPT is primarily for people who have mild to moderate, common mental health difficulties such as depression, anxiety, phobias and post traumatic stress disorder (PTSD). The programme seeks to use the least intrusive method of care possible to treat people at the time when it will be of most help to them. Individuals are able to self-refer into most IAPT services or alternatively can request to be referred by their GP or other services in the community. Richmond Wellbeing Service (RWS) is one such IAPT Service and this research is based on our work to promote accessibility of the service to one of the harder to reach population groups - older adults. We know that IAPT services could have a positive impact on older adults as it is believed on average, 25% of over 65 year olds face common mental health problems. However, only a third of these people discuss this with their GP and so are less likely to be referred to an IAPT Service. In relation to the above, this project was designed to look at increasing access for older adults into Richmond Wellbeing Service (RWS) specifically to improve access to the RWS by older adults by 100. The overall goal was to increase older adult (65+) referral rates by 20% over a year, in raw number this would translate to an increase of 100 over a year period, and in percentage terms an average of 8% of total referrals. Results yielded an increase of 39 referrals between baseline and test period. The majority of this increase had occurred in the final five months of the projects duration(31). Interestingly the number of older adults in the older age band (85+) almost doubled within this period (from 12 to 21). In total, in percentage terms this translates to an an increase of OA referrals from 6% up to 6.7%, as above we are aiming for 8% or an additional increase of 61 patients

    2012-10-15

    Nigeria experiences a remarkable paradox -- the abundance of energy resources and widespread energy poverty. Only about 40% of the population has access to the country’s grid electricity. About 72% of the population depends on traditional fuelwood for cooking. Despite this, government financing of energy services that benefits majority of Nigeria’s population has been grossly inadequate. Private sector investments and donor support have not fared better. This paper examines the current level of energy poverty in Nigeria. It analyses the level of government, private sector and donor funding for energy services that benefit the poor. It further reviews international best practices in expanding access for pro poor energy services. The paper finds a significant decline in political interest for expanding electricity services to rural areas. Even though ambitious policy reforms have commenced, agreed programmes are not implemented effectively. Not only are investments in rural electrification in decline, there is no history of annual budgeting for cooking energy programmes. The paper recommends a number of action points for expanding access to energy services that benefit the poor. These include the development and launching of a new national rural electrification strategy; establishment of a national cooking energy programme; and the development of clear policy incentives to support private sector investment in energy services for the poor. It calls on the Nigerian Central Bank of Nigeria to set aside 10% of the existing power intervention fund for pro poor energy financing; and the Nigerian Electricity Regulatory Commission to establish a clear framework for the utilization of the Consumer Assistance Fund. Other recommendations include the use of a proportion of the Ecological Fund to finance cooking energy; establishment of a donor’s platform on pro poor energy; and the mobilization of civil society in providing community-level energy services.

    2012-05-01

    Full Text Available Abstract Background Often new arrivals from refugee backgrounds have experienced poor health and limited access to healthcare services. The maternal and child health (MCH service in Victoria, Australia, is a joint local and state government operated, cost-free service available to all mothers of children aged 0–6 years. Although well-child healthcare visits are useful in identifying health issues early, there has been limited investigation in the use of these services for families from refugee backgrounds. This study aims to explore experiences of using MCH services, from the perspective of families from refugee backgrounds and service providers. Methods We used a qualitative study design informed by the socioecological model of health and a cultural competence approach. Two geographical areas of Melbourne were selected to invite participants. Seven focus groups were conducted with 87 mothers from Karen, Iraqi, Assyrian Chaldean, Lebanese, South Sudanese and Bhutanese backgrounds, who had lived an average of 4.7 years in Australia (range one month-18 years. Participants had a total of 249 children, of these 150 were born in Australia. Four focus groups and five interviews were conducted with MCH nurses, other healthcare providers and bicultural workers. Results Four themes were identified: facilitating access to MCH services; promoting continued engagement with the MCH service; language challenges; and what is working well and could be done better. Several processes were identified that facilitated initial access to the MCH service but there were implications for continued use of the service. The MCH service was not formally notified of new parents arriving with young children. Pre-arranged group appointments by MCH nurses for parents who attended playgroups worked well to increase ongoing service engagement. Barriers for parents in using MCH services included access to transportation, lack of confidence in speaking English and making

  15. SERVICE AVAILABILITY AND ACCESSIBILITY OF REQUIREMENTS USINGCLUSTERING IN CLOUD ENVIRONMENT

    Thamilvaani Arvaree Alvar

    2012-01-01

    Full Text Available Cloud computing is one contemporary technology in which the research community has recently embarked. Cloud computing faces many of the challenges and difficulties. Meeting the user needs is the important issue in any business environment. The need for quality services that satisfies both customers and service providers is very essential. Lacking of guarantees for the customer to fully satisfy with the retrieved services from the service provider for the requested requirements has been identified as the major problem statement of this study. Clustering is one of the methods that widely used in data mining especially for information retrieval. Information retrieval is a process of group similar content or files together. There are different algorithms available to do the clustering such as partitioned clustering (K-means Clustering and Hierarchical Clustering (Agglomerative Hierarchical Clustering (AHC. Due to large amount of data efficient access and exploration of information retrieval is always critical. Most of the time, user will get a long list of documents which is partially match their requirements. While searching for services or access the service, there are many irrelevant documents returned with the relevant document which meets the requirements. Therefore, clustering will be used to overcome the above problem. This technique will implemented in an application to efficiently assess the correctness (fitness of requirements measurement for the required services in cloud computing. The results or findings from the application will be the evidence to ensure meeting customer requirements more adequately while providing services. Reducing the inadequacy of meeting requirements will be the major contribution of this research with the support of the application.

  16. A SOAP Web Service for accessing MODIS land product subsets

    SanthanaVannan, Suresh K [ORNL; Cook, Robert B [ORNL; Pan, Jerry Yun [ORNL; Wilson, Bruce E [ORNL

    2011-01-01

    Remote sensing data from satellites have provided valuable information on the state of the earth for several decades. Since March 2000, the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on board NASA s Terra and Aqua satellites have been providing estimates of several land parameters useful in understanding earth system processes at global, continental, and regional scales. However, the HDF-EOS file format, specialized software needed to process the HDF-EOS files, data volume, and the high spatial and temporal resolution of MODIS data make it difficult for users wanting to extract small but valuable amounts of information from the MODIS record. To overcome this usability issue, the NASA-funded Distributed Active Archive Center (DAAC) for Biogeochemical Dynamics at Oak Ridge National Laboratory (ORNL) developed a Web service that provides subsets of MODIS land products using Simple Object Access Protocol (SOAP). The ORNL DAAC MODIS subsetting Web service is a unique way of serving satellite data that exploits a fairly established and popular Internet protocol to allow users access to massive amounts of remote sensing data. The Web service provides MODIS land product subsets up to 201 x 201 km in a non-proprietary comma delimited text file format. Users can programmatically query the Web service to extract MODIS land parameters for real time data integration into models, decision support tools or connect to workflow software. Information regarding the MODIS SOAP subsetting Web service is available on the World Wide Web (WWW) at http://daac.ornl.gov/modiswebservice.

  3. Access of rural AFDC Medicaid beneficiaries to mental health services.

    Lambert, D; Agger, M S

    1995-01-01

    This article examines geographic differences in the use of mental health services among Aid to Families with Dependent Children (AFDC)-eligible Medicaid beneficiaries in Maine. Findings indicate that rural AFDC beneficiaries have significantly lower utilization of mental health services than urban beneficiaries. Specialty mental health providers account for the majority of ambulatory visits for both rural and urban beneficiaries. However, rural beneficiaries rely more on primary-care providers than do urban beneficiaries. Differences in use are largely explained by variations in the supply of specialty mental health providers. This finding supports the long-held assumption that lower supply is a barrier to access to mental health services in rural areas. PMID:10153467

  4. Towards Emulation-as-a-Service: Cloud Services for Versatile Digital Object Access

    Dirk von Suchodoletz

    2013-06-01

    Full Text Available The changing world of IT services opens the chance to more tightly integrate digital long-term preservation into systems, both for commercial and end users. The emergence of cloud offerings re-centralizes services, and end users interact with them remotely through standardized (web-client applications on their various devices. This offers the chance to use partially the same concepts and methods to access obsolete computer environments and allows for more sustainable business processes. In order to provide a large variety of user-friendly remote emulation services, especially in combination with authentic performance and user experience, a distributed system model and architecture is required, suitable to run as a cloud service, allowing for the specialization both of memory institutions and third party service providers.The shift of the usually non-trivial task of the emulation of obsolete software environments from the end user to specialized providers can help to simplify digital preservation and access strategies. Besides offering their users better access to their holdings, libraries and archives may gain new business opportunities to offer services to a third party, such as businesses requiring authentic reproduction of digital objects and processes for legal reasons. This paper discusses cloud concepts as the next logical step for accessing original digital material. Emulation-as-a-Service (EaaS fills the gap between the successful demonstration of emulation strategies as a long term access strategy and it’s perceived availability and usability. EaaS can build upon the ground of research and prototypical implementations of previous projects, and reuse well established remote access technology.In this article we develop requirements and a system model, suitable for a distributed environment. We will discuss the building blocks of the core services as well as requirements regarding access management. Finally, we will try to present a

The main reason of not using contraception mostly because they want to have children 27.0% in urban, 28.2% rural whereas, the second reason is the fear of side effects 23.1% in urban, 16.5% rural. There is 10% of respondent did not use contraceptives, because they did not need it. Health seeking behavior of pregnant women with family planning work status has a significant relationship (prevalence ratio 1.073. The jobless mothers has better access to family planning services compared to working mother. Conclusions: Accessibility of family planning services is inadequate, because not all rural ‘Poskesdes’ equipped with infrastructure and family planning devices, a lack of knowledge of family planning in rural areas. Health seeking behavior of family planning services is mostly to the midwives, the scond is to community health centers and than polindes, ‘poskesdes’ as the ranks third.

  6. A JEE RESTful service to access Conditions Data in ATLAS

    Formica, Andrea; The ATLAS collaboration

    2015-01-01

    Usage of Conditions Data in ATLAS is extensive for offline reconstruction and analysis (for example: alignment, calibration, data quality). The system is based on the LCG Conditions Database infrastructure, with read and write access via an ad hoc C++ API (COOL), a system which was developed before Run 1 data taking began. The infrastructure dictates that the data is organized into separate schemas (assigned to subsystems/groups storing distinct and independent sets of conditions), making it difficult to access information from several schemas at the same time. We have thus created PL/SQL functions containing queries to provide content extraction at multi-schema level. The PL/SQL API has been exposed to external clients by means of an intermediate java application server (JBoss), where an application delivering access to the DB via RESTful services has been deployed. The services allow navigation over multiple schema content, via simple URLs. The queried data can be retrieved either in XML or JSON formats, vi...

  10. Web Services Provide Access to SCEC Scientific Research Application Software

    Gupta, N.; Gupta, V.; Okaya, D.; Kamb, L.; Maechling, P.

    2003-12-01

    Web services offer scientific communities a new paradigm for sharing research codes and communicating results. While there are formal technical definitions of what constitutes a web service, for a user community such as the Southern California Earthquake Center (SCEC), we may conceptually consider a web service to be functionality provided on-demand by an application which is run on a remote computer located elsewhere on the Internet. The value of a web service is that it can (1) run a scientific code without the user needing to install and learn the intricacies of running the code; (2) provide the technical framework which allows a user's computer to talk to the remote computer which performs the service; (3) provide the computational resources to run the code; and (4) bundle several analysis steps and provide the end results in digital or (post-processed) graphical form. Within an NSF-sponsored ITR project coordinated by SCEC, we are constructing web services using architectural protocols and programming languages (e.g., Java). However, because the SCEC community has a rich pool of scientific research software (written in traditional languages such as C and FORTRAN), we also emphasize making existing scientific codes available by constructing web service frameworks which wrap around and directly run these codes. In doing so we attempt to broaden community usage of these codes. Web service wrapping of a scientific code can be done using a "web servlet" construction or by using a SOAP/WSDL-based framework. This latter approach is widely adopted in IT circles although it is subject to rapid evolution. Our wrapping framework attempts to "honor" the original codes with as little modification as is possible. For versatility we identify three methods of user access: (A) a web-based GUI (written in HTML and/or Java applets); (B) a Linux/OSX/UNIX command line "initiator" utility (shell-scriptable); and (C) direct access from within any Java application (and with the

    2003-01-01

    The benefits of climate policy normally consist exclusively of the reduced impacts of climate change, i.e., the policy’s primary aim. Our analysis of benefits of climate policy suggests, however, that researchers and policymakers should also take account of ancillary benefits, e.g., in the shape of improved air quality induced by climate protection measures. A consideration of both, primary and ancillary benefits, has a positive influence on global climate protection efforts, e.g., because th...

    Ancillary experiments' are a new technique whereby researchers use a completed experiment conducted by others to recover causal estimates of a randomized intervention on new outcomes. The method requires pairing new outcome data with randomized treatments the researchers themselves did not oversee. Since ancillary experiments rely on interventions that have already been undertaken, oftentimes by governments, they can provide a low-cost method with which to identify the effects of large-scale ...

    Third party access to postal networks can be made subject to a range of access conditions. While the pricing of postal network access has received much research attention, the effects of access on quality of service have received less. Using data on international postal services in a large panel of European countries, we estimate an econometric model of average time-to-delivery for letter post, including a range of access conditions. We find that several access conditions have a significant a...

    An increasing number of information systems integrate semantic data stores for managing ontologies. To access these knowledge bases most of the available implementations provide application programming interfaces (APIs). The implementations of these APIs normally do not support any kind of network protocol or service interface. This works fine as long as a monolithic system is developed. If the need arises to integrate such a knowledge base into a service-oriented architecture a different app...

  19. Pilot evaluation of a web-based intervention targeting sexual health service access.

    Brown, K E; Newby, K; Caley, M; Danahay, A; Kehal, I

    2016-04-01

    Sexual health service access is fundamental to good sexual health, yet interventions designed to address this have rarely been implemented or evaluated. In this article, pilot evaluation findings for a targeted public health behavior change intervention, delivered via a website and web-app, aiming to increase uptake of sexual health services among 13-19-year olds are reported. A pre-post questionnaire-based design was used. Matched baseline and follow-up data were identified from 148 respondents aged 13-18 years. Outcome measures were self-reported service access, self-reported intention to access services and beliefs about services and service access identified through needs analysis. Objective service access data provided by local sexual health services were also analyzed. Analysis suggests the intervention had a significant positive effect on psychological barriers to and antecedents of service access among females. Males, who reported greater confidence in service access compared with females, significantly increased service access by time 2 follow-up. Available objective service access data support the assertion that the intervention may have led to increases in service access. There is real promise for this novel digital intervention. Further evaluation is planned as the model is licensed to and rolled out by other local authorities in the United Kingdom. PMID:26928566

  2. A Collaborative Wireless Access to On-Demand Services

    Zohar Naor

    2008-02-01

    Full Text Available A collaborative access scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. The key idea is that individual clients requesting for the same content can collaborate and share the same data channel. As opposed to broadcasting, this method enables the clients to determine online the delivered content, and thus supports on-demand services. On the other hand, a multicast content delivery is much more efficient than a unicast content distribution, which must use a dedicated data channel per each and every client. This method is particularly suitable for sessions having a long-time duration, for applications in which clients can subscribe to ahead of time, and for applications in which the clients receive the same information simultaneously. A multicast content distribution increases the network service throughput in terms of the expected number of clients served simultaneously, and therefore it offers a reduced waiting time for content delivery at highly loaded time periods. It is shown that the problem of maximizing the efficiency of distributing a content in a wireless network is NP-hard. An approximation algorithm is therefore used, that for any 0<ε<1 finds an approximation solution with a relative accuracy ε. The proposed method does not require any hardware modification on the network equipment. Thus, it can be easily implemented.

  3. Resolving mobility constraints impeding rural seniors' access to regionalized services.

    Ryser, Laura; Halseth, Greg

    2012-01-01

    Rural and small town places in developed economies are aging. While attention has been paid to the local transportation needs of rural seniors, fewer researchers have explored their regional transportation needs. This is important given policies that have reduced and regionalized many services and supports. This article explores mobility constraints impeding rural seniors' access to regionalized services using the example of northern British Columbia. Drawing upon several qualitative studies, we explore geographical, maintenance, organizational, communication, human resources, infrastructure, and financial constraints that affect seniors' regional mobility. Our findings indicate that greater coordination across multiple government agencies and jurisdictions is needed and more supportive policies and resources must be in place to facilitate a comprehensive regional transportation strategy. In addition to discussing the complexities of these geographies, the article identifies innovative solutions that have been deployed in northern British Columbia to support an aging population. This research provides a foundation for developing a comprehensive understanding of the key issues that need to be addressed to inform strategic investments in infrastructure and programs that support the regional mobility and, hence, healthy aging of rural seniors.

    Lasota, M.; McCracken, M.C.; Zanasi, L. [Informetrica Ltd., Ottawa, ON (Canada)

    2002-04-01

    This study discussed the ancillary spending that would be incurred by the Yukon Government as a result of the Alaska Highway Pipeline Project. Ancillary spending refers to investment that is needed to facilitate pipeline construction but is not directly related to the pipeline. It includes investment in roads and highways, water treatment, sewage and solid waste, air transportation, rail transportation (including the White Pass and the Canadian Arctic Railway), port development, schools, health services, and jails. It was determined that ancillary expenditures to the Yukon Government excluding health and correctional services is estimated at $6.95 to $7.85 million in pre-pipeline construction. During the 3 years of pipeline construction and the first 3 years of pipeline operation, the ancillary spending is not expected to be greater than $21.7 million. Ancillary spending includes the need to repair existing facilities and infrastructures after the pipeline is completed. This will provide employment for a variety of skilled people including engineers and trades people. Other developments associated with the AHPP may include gas field and mining development as well as developments in local gas and electricity distribution. 4 refs., 1 tab.

  9. Access Control Mechanisms for Semantic Web services-A Discussion on Requirements & Future Directions

    Gondara, Mandeep Kaur

    2011-01-01

    Semantic Web is an open, distributed, and dynamic environment where access to resources cannot be controlled in a safe manner unless the access decision takes into account during discovery of web services. Security becomes the crucial factor for the adoption of the semantic based web services. An access control means that the users must fulfill certain conditions in order to gain access over web services. Access control is important in both perspectives i.e. legal and security point of view. This paper discusses important requirements for effective access control in semantic web services which have been extracted from the literature surveyed. I have also discussed open research issues in this context, focusing on access control policies and models in this paper.

  10. Spatial analysis of elderly access to primary care services

    Lozano-Gracia Nancy

    2006-05-01

    Full Text Available Abstract Background Admissions for Ambulatory Care Sensitive Conditions (ACSCs are considered preventable admissions, because they are unlikely to occur when good preventive health care is received. Thus, high rates of admissions for ACSCs among the elderly (persons aged 65 or above who qualify for Medicare health insurance are signals of poor preventive care utilization. The relevant geographic market to use in studying these admission rates is the primary care physician market. Our conceptual model assumes that local market conditions serving as interventions along the pathways to preventive care services utilization can impact ACSC admission rates. Results We examine the relationships between market-level supply and demand factors on market-level rates of ACSC admissions among the elderly residing in the U.S. in the late 1990s. Using 6,475 natural markets in the mainland U.S. defined by The Health Resources and Services Administration's Primary Care Service Area Project, spatial regression is used to estimate the model, controlling for disease severity using detailed information from Medicare claims files. Our evidence suggests that elderly living in impoverished rural areas or in sprawling suburban places are about equally more likely to be admitted for ACSCs. Greater availability of physicians does not seem to matter, but greater prevalence of non-physician clinicians and international medical graduates, relative to U.S. medical graduates, does seem to reduce ACSC admissions, especially in poor rural areas. Conclusion The relative importance of non-physician clinicians and international medical graduates in providing primary care to the elderly in geographic areas of greatest need can inform the ongoing debate regarding whether there is an impending shortage of physicians in the United States. These findings support other authors who claim that the existing supply of physicians is perhaps adequate, however the distribution of them across

    Rosa E. Lillo

    1999-01-01

    Full Text Available We examine the service mechanism of two queueing models with two units in tandem. In the first model, customers who complete service in Unit 1 must wait in an intermediate buffer until the ongoing service in Unit II ends. In the second model, jobs can be pre-positioned in an intermediate buffer to await service in Unit II. Under the assumption of phase-type service times, the steady-state regime of the service system is studied in detail.

    2000-01-01

    California has undertaken a major restructuring of its electricity utility sector. Most electricity is now sold in open markets operated by the PX and other entities. Bilateral contracting among some market participants is also permitted. A group of independent generating companies bids into these markets together with out of state resources. In addition to these markets, CAISO operates markets for both imbalance energy and AS, a quite unusual feature of the California system. These markets were initially quite chaotic and were rife with market power problems. However, various reforms have now created a system that functions well. During the restructuring process, special provisions were made to protect public purpose programs, including renewable generation.

    2014-12-01

    Full Text Available OBJECTIVE To assess the inequalities in access, utilization, and quality of health care services according to the socioeconomic status. METHODS This population-based cross-sectional study evaluated 2,927 individuals aged ≥ 20 years living in Pelotas, RS, Southern Brazil, in 2012. The associations between socioeconomic indicators and the following outcomes were evaluated: lack of access to health services, utilization of services, waiting period (in days for assistance, and waiting time (in hours in lines. We used Poisson regression for the crude and adjusted analyses. RESULTS The lack of access to health services was reported by 6.5% of the individuals who sought health care. The prevalence of use of health care services in the 30 days prior to the interview was 29.3%. Of these, 26.4% waited five days or more to receive care and 32.1% waited at least an hour in lines. Approximately 50.0% of the health care services were funded through the Unified Health System. The use of health care services was similar across socioeconomic groups. The lack of access to health care services and waiting time in lines were higher among individuals of lower economic status, even after adjusting for health care needs. The waiting period to receive care was higher among those with higher socioeconomic status. CONCLUSIONS Although no differences were observed in the use of health care services across socioeconomic groups, inequalities were evident in the access to and quality of these services.

    With the mutual consent to use WSDL (Web Service Description Language) to describe web service interfaces and SOAP as the basic communication protocol, the cornerstone for web service-oriented architecture (WSOA) has been established. Considering the momentum observable by the growing number of specifications in the web service domain for the indispensable cross-cutting concern of identity management (IdM) it is still an open issue how a WSOA-aware IdM architecture is built and how it is link...

  7. Semantic Data Access Services at NASA's Atmospheric Science Data Center

    Huffer, E.; Hertz, J.; Kusterer, J.

    2012-12-01

    The corpus of Earth Science data products at the Atmospheric Science Data Center at NASA's Langley Research Center comprises a widely heterogeneous set of products, even among those whose subject matter is very similar. Two distinct data products may both contain data on the same parameter, for instance, solar irradiance; but the instruments used, and the circumstances under which the data were collected and processed, may differ significantly. Understanding the differences is critical to using the data effectively. Data distribution services must be able to provide prospective users with enough information to allow them to meaningfully compare and evaluate the data products offered. Semantic technologies - ontologies, triple stores, reasoners, linked data - offer functionality for addressing this issue. Ontologies can provide robust, high-fidelity domain models that serve as common schema for discovering, evaluating, comparing and integrating data from disparate products. Reasoning engines and triple stores can leverage ontologies to support intelligent search applications that allow users to discover, query, retrieve, and easily reformat data from a broad spectrum of sources. We argue that because of the extremely complex nature of scientific data, data distribution systems should wholeheartedly embrace semantic technologies in order to make their data accessible to a broad array of prospective end users, and to ensure that the data they provide will be clearly understood and used appropriately by consumers. Toward this end, we propose a distribution system in which formal ontological models that accurately and comprehensively represent the ASDC's data domain, and fully leverage the expressivity and inferential capabilities of first order logic, are used to generate graph-based representations of the relevant relationships among data sets, observational systems, metadata files, and geospatial, temporal and scientific parameters to help prospective data consumers

  8. A Service Oriented Architecture for Personalized Universal Media Access

    Ingo Brunkhorst

    2011-04-01

    Full Text Available Multimedia streaming means delivering continuous data to a plethora of client devices. Besides the actual data transport, this also needs a high degree of content adaptation respecting the end users’ needs given by content preferences, transcoding constraints, and device capabilities. Such adaptations can be performed in many ways, usually on the media server. However, when it comes to content editing, like mixing in subtitles or picture-in-picture composition, relying on third party service providers may be necessary. For economic reasons this should be done in a service-oriented way, because a lot of adaptation modules can be reused within different adaptation workflows. Although service-oriented architectures have become widely accepted in the Web community, the multimedia environment is still dominated by monolithic systems. The main reason is the insufficient support for working with continuous data: generally the suitability of Web services for handling complex data types and state-full applications is still limited. In this paper we discuss extensions of Web service frameworks, and present a first implementation of a service-oriented framework for media streaming and digital item adaptation. The focus lies on the technical realization of the services. Our experimental results show the practicality of the actual deployment of service-oriented multimedia frameworks.

  10. IVOA Recommendation: SimpleDALRegExt: Describing Simple Data Access Services

    Plante, Raymond; Harrison, Paul; Tody, Doug

    2014-01-01

    An application that queries or consumes descriptions of VO resources must be able to recognize a resource's support for standard IVOA protocols. This specification describes how to describe a service that supports any of the four fundamental data access protocols -- Simple Cone Search (SCS), Simple Image Access (SIA), Simple Spectral Access (SSA), Simple Line Access (SLA) -- using the VOResource XML encoding standard. A key part of this specification is the set of VOResource XML extension schemas that define new metadata that are specific to those protocols. This document describes in particular rules for describing such services within the context of IVOA Registries and data discovery as well as the VO Standard Interface (VOSI) and service self-description. In particular, this document spells out the essential markup needed to identify support for a standard protocol and the base URL required to access the interface that supports that protocol.

  11. Accessibility to primary health care services in the state of Goiás

    Juliana Pires Ribeiro

    2015-09-01

    Full Text Available The objective of this study was to evaluate accessibility to primary health care services in the state of Goiás. A descriptive cross-sectional study was conducted based on secondary data from the National Program to Improve Access to and Quality of Primary Health Care. The study sample was composed of health professionals from 1,216 primary health care units. Results showed that 68.5% of the health units miss a screening room, thus considerably damaging prompt decision-making by professionals. The lack of medical offices in 2% of the sites hinders the primary health care services accessibility in Goiás. As regards opening hours and work shifts, 86% of the units are open five days a week in eight-hour shifts, which does not favor accessibility for users. This study confirms the lack of accessibility to health services and the need for additional investments to strengthen primary health care.

  14. Implementation of levels of services on broadband networks with cable modem access

    Campos, Luis A.; Yu, Che-Fn

    1997-10-01

    Residential broadband access networks using technologies such as ADSL and cable modems have enabled the provisioning of emerging Internet applications such as Internet telephony, video conferencing and interactive games. These applications have specific end-to-end performance requirements from the network in order to have an acceptable performance. Currently the Internet is a best effort network which doesn't provide levels of service. There are many elements of an end-to-end network which are currently suitable to provide quality-of- service guaranties such as ATM links. Nevertheless, only with recent deployments of broadband access technologies and the introduction of Internet protocols such as RSVP, providing levels of service becomes feasible without the use expensive links to the customer site. This paper examines several network implementation options for introducing levels of service using cable modem access. Limitations imposed by the applications on the network as well as the contribution of the different network elements to level of service parameters such as end-to-end delay, throughput and jitter are examined. Concentration network architectures as well as proposed backbone configuration options for end-to-end level of service provisioning are presented. At the access network, provisioning of level of service using bandwidth control through packet throttling and through access network design providing excess bandwidth to customers are presented. HFC protocol dependent means to provide level of services including reservation and ATM based protocols are examined as well.

  15. AccessMod 3.0: computing geographic coverage and accessibility to health care services using anisotropic movement of patients

    Ebener Steeve

    2008-12-01

    Full Text Available Abstract Background Access to health care can be described along four dimensions: geographic accessibility, availability, financial accessibility and acceptability. Geographic accessibility measures how physically accessible resources are for the population, while availability reflects what resources are available and in what amount. Combining these two types of measure into a single index provides a measure of geographic (or spatial coverage, which is an important measure for assessing the degree of accessibility of a health care network. Results This paper describes the latest version of AccessMod, an extension to the Geographical Information System ArcView 3.×, and provides an example of application of this tool. AccessMod 3 allows one to compute geographic coverage to health care using terrain information and population distribution. Four major types of analysis are available in AccessMod: (1 modeling the coverage of catchment areas linked to an existing health facility network based on travel time, to provide a measure of physical accessibility to health care; (2 modeling geographic coverage according to the availability of services; (3 projecting the coverage of a scaling-up of an existing network; (4 providing information for cost effectiveness analysis when little information about the existing network is available. In addition to integrating travelling time, population distribution and the population coverage capacity specific to each health facility in the network, AccessMod can incorporate the influence of landscape components (e.g. topography, river and road networks, vegetation that impact travelling time to and from facilities. Topographical constraints can be taken into account through an anisotropic analysis that considers the direction of movement. We provide an example of the application of AccessMod in the southern part of Malawi that shows the influences of the landscape constraints and of the modes of transportation on

  3. Web service activities at the IRIS DMC to support federated and multidisciplinary access

    Trabant, Chad; Ahern, Timothy K.

    2013-04-01

    At the IRIS Data Management Center (DMC) we have developed a suite of web service interfaces to access our large archive of, primarily seismological, time series data and related metadata. The goals of these web services include providing: a) next-generation and easily used access interfaces for our current users, b) access to data holdings in a form usable for non-seismologists, c) programmatic access to facilitate integration into data processing workflows and d) a foundation for participation in federated data discovery and access systems. To support our current users, our services provide access to the raw time series data and metadata or conversions of the raw data to commonly used formats. Our services also support simple, on-the-fly signal processing options that are common first steps in many workflows. Additionally, high-level data products derived from raw data are available via service interfaces. To support data access by researchers unfamiliar with seismic data we offer conversion of the data to broadly usable formats (e.g. ASCII text) and data processing to convert the data to Earth units. By their very nature, web services are programmatic interfaces. Combined with ubiquitous support for web technologies in programming & scripting languages and support in many computing environments, web services are very well suited for integrating data access into data processing workflows. As programmatic interfaces that can return data in both discipline-specific and broadly usable formats, our services are also well suited for participation in federated and brokered systems either specific to seismology or multidisciplinary. Working within the International Federation of Digital Seismograph Networks, the DMC collaborated on the specification of standardized web service interfaces for use at any seismological data center. These data access interfaces, when supported by multiple data centers, will form a foundation on which to build discovery and access mechanisms

  4. Accessing the SEED Genome Databases via Web Services API: Tools for Programmers

    Vonstein Veronika

    2010-06-01

    Full Text Available Abstract Background The SEED integrates many publicly available genome sequences into a single resource. The database contains accurate and up-to-date annotations based on the subsystems concept that leverages clustering between genomes and other clues to accurately and efficiently annotate microbial genomes. The backend is used as the foundation for many genome annotation tools, such as the Rapid Annotation using Subsystems Technology (RAST server for whole genome annotation, the metagenomics RAST server for random community genome annotations, and the annotation clearinghouse for exchanging annotations from different resources. In addition to a web user interface, the SEED also provides Web services based API for programmatic access to the data in the SEED, allowing the development of third-party tools and mash-ups. Results The currently exposed Web services encompass over forty different methods for accessing data related to microbial genome annotations. The Web services provide comprehensive access to the database back end, allowing any programmer access to the most consistent and accurate genome annotations available. The Web services are deployed using a platform independent service-oriented approach that allows the user to choose the most suitable programming platform for their application. Example code demonstrate that Web services can be used to access the SEED using common bioinformatics programming languages such as Perl, Python, and Java. Conclusions We present a novel approach to access the SEED database. Using Web services, a robust API for access to genomics data is provided, without requiring large volume downloads all at once. The API ensures timely access to the most current datasets available, including the new genomes as soon as they come online.

    2012-06-01

    Full Text Available In Internet of Things, computing and processing of information is the core supporting. In this paper, we introduce “Service-Oriented Computing” to solve the computing and processing of information in IoT. However, a key challenge in service-oriented environment is the design of effective access control schemas.We put forward a model of Workflow -oriented Attributed Based Access Control (WABAC, and an access control framework based on WABAC model. WABAC model grants and adapts permissions to subjects according to subject atttribute, resource attribute, environment attribute and current task, meeting access control request of SOC. Using the approach presented can effectively enhance the access control security for SOC applications, and prevent the abuse of subject permissions.

  1. An interaction-based access control model (IBAC) for collaborative services

    Altunay, Mine; /Fermilab; Byrd, Gregory T.; Brown, Doug E.; Dean, Ralph A.; /North Carolina State U.

    2008-04-01

    A collaboration is a collection of services that work together to achieve a common goal. Although collaborations help when tackling difficult problems, they lead to security issues. First, a collaboration is often performed by services that are drawn from different security domains. Second, a service interacts with multiple peer services during the collaboration. These interactions are not isolated from one another--e.g., data may flow through a sequence of different services. As a result, a service is exposed to multiple peer services in varying degrees, leading to different security threats. We identify the types of interactions that can be present in collaborations, and discuss the security threats due to each type. We propose a model for representing the collaboration context so that a service can be made aware of the existing interactions. We provide an access control model for a service participating in a collaboration. We couple our access control model with a policy model, so that the access requirements from collaborations can be expressed and evaluated.

    2007-10-01

    Full Text Available Abstract Background International research shows that injecting drug users (IDUs can encounter many barriers when they try to access drug treatment and other services. However, the existing literature is mostly quantitative and does not consider the kinds of factors that injectors themselves identify as enabling them to access and benefit from services. Responding to this gap in knowledge, our paper explores IDUs' own suggestions for improving service engagement and their reports of other factors enabling them to seek help. Methods Semi-structured qualitative interviews were conducted with 75 current illicit drug injectors in three geographically diverse areas of West Yorkshire, England. Recruitment was through needle exchange programmes, with additional snowball sampling to ensure inclusivity of gender, ethnicity and primary drug injected. Transcribed data were analysed thematically using Framework. Results Although participants were often satisfied with current access to services, they made three broad suggestions for improving engagement. These were: providing more services (more providers and more forms of support; better operation of existing services (including better communication systems and more flexibility around individual needs; and staffing-related improvements (particularly, less judgemental and more understanding staff attitudes. Other factors identified as important enablers of help seeking were: having supporting relationships (particularly with family members; personal circumstances/life events (especially becoming a parent; and an injector's state of mind (such as feeling motivated and positive. Conclusion A range of practical suggestions for improving IDUs' access to drug treatment and other services are identified.

    2015-06-01

    Full Text Available This study assessed the association between accessibility of catering service venues and adolescents’ alcohol use over the previous 30 days. The data were collected from cross-sectional surveys conducted in 2014, 2223 students at 27 high schools in Chaoyang and Xicheng districts, Beijing using self-administered questionnaires to collect the adolescents information on socio-demographic characteristics and recent alcohol experiences. The accessibility of, and proximity to, catering service venues were summarized by weights, which were calculated by multiplication of the type-weight and the distance-weight. All sampled schools were categorized into three subgroups (low, middle, and high geographic density based on the tertile of nearby catering service venues, and a multi-level logistic regression analysis was performed to explore variance between the school levels. Considering the setting characteristics, the catering service venues weighted value was found to account for 8.6% of the school level variance of adolescent alcohol use. The odds ratios (OR and 95% confidence intervals (CI of drinking over the past 30-days among adolescents with medium and high accessibility of catering service venues were 1.17 (0.86, 1.57 and 1.47 (1.06, 2.02, respectively (p < 0.001 for trend test. This study addressed a gap in the adolescent drinking influence by the catering service venues around schools in China. Results suggest that the greater accessibility of catering service venues around schools is associated with a growing risk of recent drinking.

  5. A Semantic Context-Based Model for MobileWeb Services Access Control

    Haibo Shen

    2011-02-01

    Full Text Available As mobile web services becomes more pervasive, applications based on mobile web services will need flexible access control mechanisms. Unlike traditional approaches based on the identity or role for access control, access decisions for these applications will depend on the combination of the required attributes of users and the contextual information. This paper proposes a semantic context-based access control model (called SCBAC to be applied in mobile web services environment by combining semantic web technologies with context-based access control mechanism. The proposed model is a context-centric access control solutions, context is the first-class principle that explicitly guides both policy specification and enforcement process. In order to handle context information in the model, this paper proposes a context ontology to represent contextual information and employ it in the inference engine. As well as, this paper specifies access control policies as rules over ontologies representing the concepts introduced in the SCBAC model, and uses semantic web rule language (SWRL to form policy rule and infer those rules by JESS inference engine. The proposed model can also be applied to context-aware applications.

  6. Government policy and access to natural gas service in Canada

    As part of the Canadian energy policy between the mid-1970's to the mid-1980's, consumers were encouraged to use fuels alternative to oil. The first set of policy issues involved measures to provide consumers with incentives to switch to non-oil-burning equipment, whereas the second set of. policy papers emphasized the expansion of the natural gas distribution system. More than $1 billion have been spent on the gas pipeline expansion project. Consequences of program expenditures in each province were examined. With the exception of Manitoba, it was found that annual net pipeline additions were higher during the program period, indicating that the program policies induced these activities to occur sooner than if the policies were not in place. Kilometres of gas pipeline per individual constructed was highest in Quebec, where construction proceeded mainly between the more densely populated centres. In contrast, in Saskatchewan and Alberta, the program encouraged natural gas pipeline construction in rural areas with lower populations. Without the program, these areas may not have had access to natural gas for a very long time. It was concluded that, in this, and some other instances, public investment had the effect of accelerating developments, or encouraging the completion of projects that otherwise would not have been undertaken. It was suggested that in the future decision-makers consider the costs of changes in activity patterns prior to designing such programs. 2 figs., 1 table

  7. Data Access Services interoperability in the Geosciences by means of the GI-axe Brokering Framework

    Boldrini, Enrico; Santoro, Mattia; Papeschi, Fabrizio; Nativi, Stefano

    2013-04-01

    Many software tools are in use in the different Geosciences domains to the aim of publishing, accessing, evaluating and using available datasets in a service based environment. These tools/services are often domain-specific and usually support a small and disciplinary set of protocols and data models. On the other hand, multidisciplinary applications need to access many of these tools/services belonging to different domains in order to retrieve heterogeneous datasets (e.g. satellite acquired gridded coverages and in-situ sensor time series), then "uniformly process them" and achieve a deeper insight. Moreover datasets, to be easily processed, should be available according to a given Common Grid Environment (CGE): i.e. a geospatial environment characterized by a common spatio-temporal CRS (Coordinate Reference System), resolution, extension and by a common format encoding. Now, the interoperability effort needed by multidisciplinary applications is ordinarily in charge of data providers servers or user clients: in both cases, this represents a high entry barrier. The GI-axe Access Broker addresses this interoperability issue by taking charge of the needed implementation effort. It acts as an intermediation service between the User Clients and the Data Provider Services, placing itself in a third party (Broker) Layer. Indeed the Access Broker can access datasets available through well known access services in use by the Geosciences communities (e.g. OGC WCS, WMS, WFS, OPeNDAP, FTP, REST APIs, …) and republish them according to the application client interfaces. Moreover, GI-axe transforms datasets according to the a CGE specified by Users. In doing so it may resort to external processing services already in use by the community, supplementing the functionalities already supported by the data provider services. The external processing services list can be configured by Users. GI-axe is also a flexible framework, composed of extensible components. This architecture

    Full Text Available Background: Inequalities in healthcare between population groups of South Africa existed during the apartheid era and continue to exist both between and within many population groups. Accessibility and affordability of healthcare is a human right.Objectives: The aim of the study was to explore and describe accessibility, affordability and the use of health services by the mixed race (coloured population in the Western Cape, South Africa.Method: A cross-sectional descriptive, non-experimental study with a quantitative approach was applied. A purposive convenient sample of 353 participants (0.6% was drawn from a population of 63 004 economically-active people who lived in the residential areas as defined for the purpose of the study. All social classes were represented. The hypothesis set was that there is a positive relationship between accessibility, affordability and the use of health services. A pilot study was conducted which also supported the reliability and validity of the study. Ethics approval was obtained from the University of Stellenbosch and informed consent from respondents. A questionnaire was used to collect the data.Results: The hypothesis was accepted. The statistical association between affordability (p = < 0.01, accessibility (p = < 0.01 and the use of health services was found to be significant using the Chi-square (χ² test.Conclusion: The study has shown how affordability and accessibility may influence the use of healthcare services. Accessibility is not only the distance an individual must travel to reach the health service point but more so the utilisation of these services. Continuous Quality Management should be a priority in healthcare services, which should be user-friendly.

  10. Programmatic access to data and information at the IRIS DMC via web services

    Weertman, B. R.; Trabant, C.; Karstens, R.; Suleiman, Y. Y.; Ahern, T. K.; Casey, R.; Benson, R. B.

    2011-12-01

    The IRIS Data Management Center (DMC) has developed a suite of web services that provide access to the DMC's time series holdings, their related metadata and earthquake catalogs. In addition, services are available to perform simple, on-demand time series processing at the DMC prior to being shipped to the user. The primary goal is to provide programmatic access to data and processing services in a manner usable by and useful to the research community. The web services are relatively simple to understand and use and will form the foundation on which future DMC access tools will be built. Based on standard Web technologies they can be accessed programmatically with a wide range of programming languages (e.g. Perl, Python, Java), command line utilities such as wget and curl or with any web browser. We anticipate these services being used for everything from simple command line access, used in shell scripts and higher programming languages to being integrated within complex data processing software. In addition to improving access to our data by the seismological community the web services will also make our data more accessible to other disciplines. The web services available from the DMC include ws-bulkdataselect for the retrieval of large volumes of miniSEED data, ws-timeseries for the retrieval of individual segments of time series data in a variety of formats (miniSEED, SAC, ASCII, audio WAVE, and PNG plots) with optional signal processing, ws-station for station metadata in StationXML format, ws-resp for the retrieval of instrument response in RESP format, ws-sacpz for the retrieval of sensor response in the SAC poles and zeros convention and ws-event for the retrieval of earthquake catalogs. To make the services even easier to use, the DMC is developing a library that allows Java programmers to seamlessly retrieve and integrate DMC information into their own programs. The library will handle all aspects of dealing with the services and will parse the returned

    William Dubinski; Leighl, Natasha B.; Ming-Sound Tsao; David M. Hwang

    2012-01-01

    The pathologic diagnosis of lung cancer historically has relied primarily on morphologic features of tumors in histologic sections. With the emergence of new targeted therapies, the pathologist is called upon increasingly to provide not only accurate typing of lung cancers, but also to provide prognostic and predictive information, based on a growing number of ancillary tests, that may have significant impact on patient management. This review provides an overview of ancillary tests currently...

  12. Access to general practitioner services amongst underserved Australians: a microsimulation study

    Schofield Deborah J

    2012-01-01

    Full Text Available Abstract Background One group often identified as having low socioeconomic status, those living in remote or rural areas, are often recognised as bearing an unequal burden of illness in society. This paper aims to examine equity of utilisation of general practitioner services in Australia. Methods Using the 2005 National Health Survey undertaken by the Australian Bureau of Statistics, a microsimulation model was developed to determine the distribution of GP services that would occur if all Australians had equal utilisation of health services relative to need. Results It was estimated that those who are unemployed would experience a 19% increase in GP services. Persons residing in regional areas would receive about 5.7 million additional GP visits per year if they had the same access to care as Australians residing in major cities. This would be a 18% increase. There would be a 20% increase for inner regional residents and a 14% increase for residents of more remote regional areas. Overall there would be a 5% increase in GP visits nationally if those in regional areas had the same access to care as those in major cities. Conclusion Parity is an insufficient goal and disadvantaged persons and underserved areas require greater access to health services than the well served metropolitan areas due to their greater poverty and poorer health status. Currently underserved Australians suffer a double disadvantage: poorer health and poorer access to health services.

  13. Remote information service access system based on a client-server-service model

    Konrad, Allan M.

    1996-01-01

    A local host computing system, a remote host computing system as connected by a network, and service functionalities: a human interface service functionality, a starter service functionality, and a desired utility service functionality, and a Client-Server-Service (CSS) model is imposed on each service functionality. In one embodiment, this results in nine logical components and three physical components (a local host, a remote host, and an intervening network), where two of the logical components are integrated into one Remote Object Client component, and that Remote Object Client component and the other seven logical components are deployed among the local host and remote host in a manner which eases compatibility and upgrade problems, and provides an illusion to a user that a desired utility service supported on a remote host resides locally on the user's local host, thereby providing ease of use and minimal software maintenance for users of that remote service.

  16. Addressing Service Access Barriers for Homeless Youth: A Call for Collaboration

    Jeffrey L. PERRON

    2014-06-01

    Full Text Available Homeless youth are among the most vulnerable individuals in North American society. The day-to-day stressors they face while living on the streets pose a great threat to their mental and physical health. A number of barriers that youth face in accessing care have been identified in the literature. This discussion article highlights work that has been done to apply geographic theory to issues of service access among homeless youth. To date, most such work has been theoretical in nature, with collaborations between geographers and homeless youth researchers to make applied recommendations for the location of services. Urban geographers and homeless youth researchers are implored to collaborate in order to make recommendations that will increase the access to service, particularly for rural homeless youth.

  17. Satisfaction with Access to Health Services: The Perspective of Estonian Patients with Rheumatoid Arthritis

    Kaja Põlluste

    2012-01-01

    Full Text Available In this cross-sectional study we explained the possible determinants of satisfaction with access to health services in patients with rheumatoid arthritis (RA. Of the 2000 randomly selected Estonian adult patients with RA, a total 1259 completed the survey. Regression analysis was used to analyse the predictors of patients' satisfaction with access to health services. Half of the respondents were satisfied with their access to health services. Factors that had a negative impact on satisfaction included pain intensity, longer waiting times to see the doctors, as well as low satisfaction with the doctors. Transportation costs to visit a rheumatologist and higher rehabilitation expenses also affected the degree of satisfaction. Patients who could choose the date and time at which they could visit the rheumatologist or who could visit their “own” doctor were more likely to be satisfied than patients whose appointment times were appointed by a healthcare provider.

    Remote access to dynamically changing information elements is a required functionality for various network services, including routing and instances of context-sensitive networking. Three fundamentally different strategies for such access are investigated in this paper: (1) a reactive approach initiated by the requesting entity, and two versions of proactive approaches in which the entity that contains the information element actively propagates its changes to potential requesters, either (2)...

  1. Access to and use of infertility services in the United States: framing the challenges.

    Adashi, Eli Y; Dean, Laura A

    2016-05-01

    An overview of access to and use of general infertility and assisted reproductive technology (ART) services in the United States (U.S.) shows a declining trend for the ever-use of infertility services. Moreover, the use of ART services lags relative to other member nations of the Organization for Economic Co-operation and Development (OECD). Access to and use of general infertility and ART services is primarily undermined by a severely constrained underwriting universe dominated by self-insured employers and by a finite number of state infertility insurance mandates. The contribution of traditional public and private payers to the underwriting of ART is limited. As compared with OECD member nations wherein the access to and underwriting of general infertility and ART services is universal, the current status quo in the U.S. can only be characterized as dismal. Further, the current state of affairs is socially unjust in that the right to build a family in the face of infertility appears to have become a function of economic prowess. Given the dominance of the self-insured employers as underwriters of general infertility and ART services, advocacy directed at this interest group is likely to prove most productive. Improving the state of underwriting of general infertility and ART services in the U.S. must be embraced as a central moral imperative and as an unwavering strategic goal of the professional societies entrusted with the reproductive health of women and men.

  2. Living large: the experiences of large-bodied women when accessing general practice services

    Russell N

    2013-09-01

    Full Text Available INTRODUCTION: Numerous studies report high levels of stigma and discrimination experienced by obese/overweight women within the health care system and society at large. Despite general practice being the most utilised point of access for health care services, there is very little international or national exploration of the experiences of large-bodied women (LBW accessing these services. The aim of this study was to explore LBW's experiences of accessing general practice services in New Zealand. METHODS: This is a qualitative, descriptive, feminist study. Local advertising for participants resulted in eight self-identified, large-bodied women being interviewed. A post-structural feminist lens was applied to the data during thematic analysis. FINDINGS: The women in this study provided examples of verbal insults, inappropriate humour, negative body language, unmet health care needs and breaches of dignity from health care providers in general practice. Seven themes were identified: early experiences of body perception, confronting social stereotypes, contending with feminine beauty ideals, perceptions of health, pursuing health, respecting the whole person, and feeling safe to access care. CONCLUSION: Pressure for body size vigilance has, in effect, excluded the women in this study from the very locations of health that they are 'encouraged' to attend-including socialising and exercising in public, screening opportunities that require bodily exposure, and accessing first point of care health services.

    Web services are starting to be widely used in applications for remotely accessing data. This is of special interest for research based on small and medium scale fusion devices, since scientists participating remotely to experiments are accessing large amounts of data over the Internet. Recent tests were conducted to see how the new network traffic, generated by the use of web services, can be integrated in the existing infrastructure and what would be the impact over existing applications, especially those used in a remote participation scenario

  5. Location- and Time-Dependent VPD for Privacy-Preserving Wireless Accesses to Cloud Services

    Yoon, Jong P

    2011-01-01

    The advent of smartphones in recent years has changed the wireless landscape. Smartphones have become a platform for online user interface to cloud databases. Cloud databases may provide a large set of user-private and sensitive data (i.e., objects), while smartphone users (i.e., subjects) provide location-sensitive information. Secure and private services in wireless accessing to cloud databases have been discussed actively for the past recent years. However, the previous techniques are unsatisfactory for dynamism of moving subjects' wireless accesses. In this paper, we propose a novel technique to dynamically generate virtual private databases (VPD) for each access by taking subjects' location and time information into account. The contribution of this paper includes a privacy-preserving access control mechanism for dynamism of wireless access.

  6. Access to eye health services among indigenous Australians: an area level analysis

    Kelaher Margaret

    2012-09-01

    Full Text Available Abstract Background This project is a community-level study of equity of access to eye health services for Indigenous Australians. Methods The project used data on eye health services from multiple sources including Medicare Australia, inpatient and outpatient data and the National Indigenous Eye Health Survey. The analysis focused on the extent to which access to eye health services varied at an area level according to the proportion of the population that was Indigenous (very low = 0-1.0%, low = 1.1-3.0%, low medium = 3.1-6.0%, high medium = 6.1-10.0%, high = 10.1-20.0%, very high = 20 + %. The analysis of health service utilisation also took into account age, remoteness and the Socioeconomic Indices for Areas (SEIFA. Results The rate of eye exams provided in areas with very high Indigenous populations was two-thirds of the rate of eye exams for areas with very low indigenous populations. The cataract surgery rates in areas with high medium to very high Indigenous populations were less than half that reference areas. In over a third of communities with very high Indigenous populations the cataract surgery rate fell below the World Health Organization (WHO guidelines compared to a cataract surgery rate of 3% in areas with very low Indigenous populations. Conclusions There remain serious disparities in access to eye health service in areas with high Indigenous populations. Addressing disparities requires a co-ordinated approach to improving Indigenous people’s access to eye health services. More extensive take-up of existing Medicare provisions is an important step in this process. Along with improving access to health services, community education concerning the importance of eye health and the effectiveness of treatment might reduce reluctance to seek help.

    2005-01-01

    The authors examine the impact of local politics and government structure on the allocation of publicly subsidized (SUS) health services across municipios (counties) in Brazil, and on the probability that uninsured individuals who require medical attention actually receive access to those health services. Using data from the 1998 PNAD survey they demonstrate that higher per capita levels of SUS doctors, nurses, and clinic rooms increase the probability that an uninsured individual gains acces...

  9. Disparities in Access to Easy-to-Use Services for Children with Special Health Care Needs.

    2016-05-01

    Objectives Families, clinicians and policymakers desire improved delivery of health and related services for children with special health care needs (CSHCN). We analyzed factors associated with ease of use in obtaining such services. We also explored what were specific difficulties or delays in receiving services. By examining data from the National Survey of Children with Special Health Care Needs (NS-CSHCN 2009-2010) and using the revised criteria for "ease of use," we were able to assess the percentage of parents who reported that their experiences seeking services for their children met those criteria. Methods We performed Chi square tests to examine associations between the independent variables and their relationship to the difficulties or delays assessed in the survey; including: eligibility, availability of services, waiting lists, cost, and access to information. We used logistic regression to determine the association of meeting the "ease of use" criteria with socio-demographic, complexity of need, and access variables. Results Overall, a third of families of CSHCN (35.3 %) encounter difficulties, delays, or frustrations in obtaining health and related services. The lack of access to health and community services in this study fell most heavily on children from racial/ethnic minority backgrounds, those in poverty, and those with complex emotional/behavioral or developmental needs and functional limitations. Conclusions for Practice CSHCN require services from a broad array of providers across multiple systems. Unfortunately, there are certain difficulties that hamper the accessibility of these systems. These findings underscore the need for both practice-level response and systems-level reform to ensure equitable distribution of health and community resources. PMID:26728898

  10. Are social franchises contributing to universal access to reproductive health services in low-income countries?

    Sundari Ravindran, T K; Fonn, Sharon

    2011-11-01

    A social franchise in health is a network of for-profit private health practitioners linked through contracts to provide socially beneficial services under a common brand. The early 21st century has seen considerable donor enthusiasm for promoting social franchises for the provision of reproductive health services. Based on a compendium of descriptive information on 45 clinical social franchises, located in 27 countries of Africa, Asia and Latin America, this paper examines their contribution to universal access to comprehensive reproductive health services. It finds that these franchises have not widened the range of reproductive health services, but have mainly focused on contraceptive services, and to a lesser extent, maternal health care and abortion. In many instances, coverage had not been extended to new areas. Measures taken to ensure sustainability ran counter to the objective of access for low-income groups. In almost two-thirds of the franchises, the full cost of all services had to be paid out of pocket and was unaffordable for low-income women. While standards and protocols for quality assurance were in place in all franchises, evidence on adherence to these was limited. Informal interviews with patients indicated satisfaction with services. However, factors such as difficulties in recruiting franchisees and significant attrition, franchisees' inability to attend training programmes, use of lay health workers to deliver services without support or supervision, and logistical problems with applying quality assurance tools, all raise concerns. The contribution of social franchises to universal access to reproductive health services appears to be uncertain. Continued investment in them for the provision of reproductive health services does not appear to be justified until and unless further evidence of their value is forthcoming. PMID:22118144
