    Full Text Available The purpose of this research was to preliminarily study the Mae Moh lignite grindability tests emphasizing onHardgrove grindability and approximate work index determination respectively. Firstly, the lignite samples were collected,prepared and analyzed for calorific value, total sulfur content, and proximate analysis. After that the Hardgrove grindabilitytest using ball-race test mill was performed. Knowing the Hardgrove indices, the Bond work indices of some samples wereestimated using the Aplan’s formula. The approximate work indices were determined by running a batch dry-grinding testusing a laboratory ball mill. Finally, the work indices obtained from both methods were compared. It was found that allsamples could be ranked as lignite B, using the heating value as criteria, if the content of mineral matter is neglected. Similarly,all samples can be classified as lignite with the Hargrove grindability indices ranging from about 40 to 50. However, there isa significant difference in the work indices derived from Hardgrove and simplified Bond grindability tests. This may be due todifference in variability of lignite properties and the test procedures. To obtain more accurate values of the lignite workindex, the time-consuming Bond procedure should be performed with a number of corrections for different milling conditions.With Hardgrove grindability indices and the work indices calculated from Aplan’s formula, capacity of the roller-racepulverizer and grindability of the Mae Moh lignite should be investigated in detail further.

    Investigations into the effects of moisture and coal blending on Hardgrove Grindability Index (HGI) were carried out on Collie coal of Western Australia. Experiments were conducted in a standard Hardgrove apparatus on four individual Premier seam coals (namely P2, P3, P4 and Hebe) and several blends (namely Hebe/P2, Hebe/P3, Hebe/P4, Hebe/P2/P4) prepared at various blending ratios. The experiments comprised of 5 days of air-drying followed by oven drying. Among the coal seams tested, Hebe showed the highest HGI (58) whereas P4 was the lowest (47). HGI was found to correlate well with residual moisture, with correlation coefficients ranging from 0.5 to 0.9 depending on the type of coal seam or blend. In contrast, moisture measurements on the samples loaded into the HGI apparatus (size 0.600 to 1.180 mm), referred to as the 'coarse fraction' showed erratic trends with HGI. The experimental results suggest that no relationship exist between the coarse fraction moisture and HGI. Measured HGI values of binary and ternary blends were found to correspond well with the weighted average values of HGI within {+-}2 HGI units. This effect was confirmed by a further investigation with a range of 11 binary (P3/Hebe) blends of various proportions.

    Investigations into the effects of moisture and coal blending on Hardgrove Grindability Index (HGI) were carried out on Collie coal of Western Australia. Experiments were conducted in a standard Hardgrove apparatus in two stages comprising three Premier seam coals (namely P2, P4 and Hebe) and several blends (namely Hebe/P2, Hebe/P4, Hebe/P2/P4) prepared at various blending ratios. Stage 1 experiments comprised of five days of air-drying followed by oven drying. Stage 2 experiments followed the procedure of overnight air drying with 2 and 4 hours oven drying at 40{sup o}C on successive days. HGI was found to correlate well with residual moisture in both stages of experiments, with correlation coefficients ranging from 0.5-0.9 depending on the type of coal seam or blend. In contrast, moisture measurements on HGI samples (0.6-1.8 mm fraction) showed erratic trends with HGI. Both Stage 1 and Stage 2 experimental results suggest that no relationship exist between HGI sample moisture and HGI.

    Full Text Available This paper presents results of investigations of torrefied biomass grindability using a modified Hardgrove test. The following types of torrefied biomass were used during the testing: alder chips, palm kernel shells and willow chips. Tests were conducted in a standard Hardgrove test mill for 50 cm3 volumetric samples (the same volume as applied in [1]. Volumetric samples of raw biomass were also tested for comparison purposes. Two ranges of the sample particle size were applied during the investigations: 0.6-1.18 mm (as in [2] and 0.2-1.18 mm. As opposed to the standard Hardgrove test, the cumulative passing mass of the product was determined for a wider range of passing of standard sieves. The obtained results point to an increase in the grindability of torrefied fuels compared to raw biomass. They can be used to categorize torrefied biomass fuels due to their grindability, and as basic information in semi-technical scale studies on torrefied biomass comminution features.

    Grindability index of coal is an important technological parameter to understand the behaviour and assess the relative hardness of coals of varying ranks and grades during comminution. This is usually determined by Hardgrove Grindability Index (HGI), which involves requirement of a costly grinding equipment and accessories not readily available and affordable. Due to heterogeneous character of coals as regards maturity, petrological constituents, mineral impurities, etc. as well as mechanism of comminution render such determination rather difficult, leading to poor reproducibility and repeatability of HGI value, contrary to other analyses for coal characterisation. As such, it often gives misleading results to understand and explain properties emerging from other analyses and testing. In view of such problems, many attempts have been done in the past to develop correlation of HGI with simple analytical composition of coal. In this perspective a fresh attempt in arriving at a more reliable and reproducible correlation with proximate analysis alone is reported. Such an index termed as Statistical Grindability Index (SGI), may be found useful in assessment of coal behaviour not only in crushing and grinding of coal but also its friability vis-a-vis dust emission during comminution.

  8. Solid fuel grindability: a literature review

    2007-07-01

    The most commonly used measurement of coal grindability is the Hardgrove Grindability Index (HGI) however, many solid fuels do not exhibit the grinding performance predicted by this index. Parameters which can influence grindability and possibly lead to inaccurate prediction of grindability as determined by HGI include: composition and texture, mineral components, brittleness, and rank (which establishes carbon, volatile matter, and moisture contents). Descriptions of these parameters are provided. Alternative measurements of grindability from literature are presented. The most promising may be a revision on the standard HGI, in which a mill capacity factor is derived from the number of mill rotations to crush coal to a specific fineness. 88 refs.

    This paper presents briefly the standard grindability testing methods such as Bond- and Hardgrove process. Then the study shows two relatively fast alternative way for the determination of specific grinding work and Bond work index of brittle materials. The standard laboratory grindability tests can be applied to the grinding of materials in a relatively coarse particle size interval (Bond method: x {lt} 3.36 mm, Hardgrove: x = 0.59-1.19 mm, Zeisel process: x = 0.75-1.00 mm). However, there has been huge industrial demand for the production of different kind of fine materials for few decades. The feed material particle size is generally below 50-100 {mu} m. That is way the reliable mill dimensioning demands the investigation of the grindability of fine materials. One of the main aims of the grindability research is to develop a grindability determination method, mainly for fine materials, by means of the improvement of Hardgrove and Bond measuring methods and devices. Therefore, the Hardgrove- and Bond mills were equipped with torque and power input measuring instruments (torque-meter, electric energy meter). Standard and modified Bond- and Hardgrove tests were carried out systematically with different kind of brittle materials in the standard particle size range. Furthermore, locked-cycle grinding experiments were completed with Universal Hardgrove mill in order to compare the results with the values obtained previously by the 'one-step' Hardgrove grindability test. The results proved the reliability of the new modified tests. Thereafter experiment series were performed with fine materials such as alumina and power station coal fly ash. In case of alumina sample the laboratory specific grinding work results were compared with those values of industrial ball mill.

    This paper presents the experimental results on the Hardgrove and Bond grindabilities of the Hungarian lignite and its isolated textural components. It is shown that for such heterogeneous materials as lignites, the Hardgrove grindability index can be used only as a quantitative feature. Nevertheless the Bond-work index is the genuine grindability parameter. A Smith formula for re-calculating the Bond-work index from the Hardgrove grindability is also analysed. A self-developing algorithm for the simulation of Bond grindability is introduced. This algorithm fits the experimental data better than the ones proposed earlier and, at the same time, has shorter testing times. It was proved experimentally that selective grinding was an effective technique for producing an advanced solid fuel or other products with low ash and high humic acid contents from lignites having a high tendency for size degradation. The paper also deals with the theoretical and experimental possibilities of the further improvement of the advanced lignite product by steam dehydration.

    Full Text Available Thermal power plants in the Republic of Serbia are making considerable efforts and even more considerable investments, not only to maintain electricity production at maximum design levels, but even to additionally increase the power output of existing generating units. Capacities of mills used in pulverized coal preparation are identified as one of the main constraints to achieving maximum mill plant capacity, while coal grindability is seen as one of the factors that directly affect capacities of the coal mills utilized in thermal power plants. The paper presents results of experimental investigation conducted for the purpose of determining Hardgrove grindability index of coal. The investigation was conducted in accordance with ISO 5074 and included analysis of approximately 70 coal samples taken from the open pit mine of Kolubara coal basin. Research results obtained indicate that coal rich in mineral matter and thus, of lower heating value is characterized by higher grindability index. Therefore, analyses presented in the paper suggest that characteristics of solid fuels analyzed in the research investigation conducted are such that the use coals less rich in mineral matter i. e. coals characterized by lower grindability index will cause coal mills to operate at reduced capacity. This fact should be taken into account when considering a potential for electricity production increase.

    Although there are several formulas available for predicting Hardgrove grindability of coal, most of them are linear and do not simultaneously take into consideration most of the relevant factors. The artificial neural network is an information processing tool that is capable of establishing an input-output relationship by extracting controlling features from a database presented to the network. In this paper, a neural network approach was proposed to deal with the grindability behavior of coal. 195 sets of experimental data were evaluated with artificial neural network to predict the HGI of Kentucky coals. Two different kinds of the trained artificial neural network were undertaken using the database created in this study. It is shown from the examples that the artificial neural network adequately recognized the characteristics of the coal experimental data sets, retaining a generality for further prediction. It is believed that an artificial neural network based prediction procedure shown in this paper can be further employed for Hardgrove grindability index prediction. The influence of liptinite, vitrinite, ash, and sulfur content on HGI was studied by a parametric study. (author)

  13. Improved grindability test: essential refinements to method

    Under Project C12063 a test was developed and demonstrated which overcame all of the deficiencies of the Standard Hardgrove Grindability Index (HGI) Test. It used a standard volume of a representative 'by zero' sample, and expressed the results of the standard grind in terms of the Sauter mean diameter, SMD (in {mu}m). The test was named the Improved Grindability Test (IGT). In Project C13065 a steady state IGT was developed. A modification to the method was needed to overcome the effect of prior breakage and this was the basis for this project. Six coals of widely varying type were sampled at exposed coal faces i.e. with no prior breakage history. These were dropped repeatedly, crushed to pass 50 mm, and divided into A and B streams. A was 'gently' crushed to pass 8 mm (jaw crusher), while B was 'vigorously' crushed to pass 8 mm. Each -8 mm sample was then crushed to pass 2 mm by passing about ten times through a plate mill with progressively closer settings. The results have shown that the effects of prior breakage history can be substantially minimised, although not completely eliminated (especially for the softest coals), by increasing the starting sample top size from 4.75 to 8 mm and crushing all of the sample each time, for a large number of passes, to the 2 mm top size for the IGT test. Testing outcomes, and the interpretation of results, have been significantly compromised by sample losses during preparation and testing. Precision at a given laboratory seems acceptable, although agreement between laboratories is disappointing. The Steady State version of the IGT shows great promise, with the mass% of -75 {mu}m produced by grinding, under 'steady state' conditions (5 minutes) being a useful indicator of a coal's grindability.

    The effects of proximate and ultimate analysis, maceral content, and coal rank (R{sub max}) for a wide range of Kentucky coal samples from calorific value of 4320 to 14960 (BTU/lb) (10.05 to 34.80 MJ/kg) on Hardgrove Grindability Index (HGI) have been investigated by multivariable regression and artificial neural network methods (ANN). The stepwise least square mathematical method shows that the relationship between (a) Moisture, ash, volatile matter, and total sulfur; (b) ln (total sulfur), hydrogen, ash, ln ((oxygen + nitrogen)/carbon) and moisture; (c) ln (exinite), semifusinite, micrinite, macrinite, resinite, and R{sub max} input sets with HGI in linear condition can achieve the correlation coefficients (R{sup 2}) of 0.77, 0.75, and 0.81, respectively. The ANN, which adequately recognized the characteristics of the coal samples, can predict HGI with correlation coefficients of 0.89, 0.89 and 0.95 respectively in testing process. It was determined that ln (exinite), semifusinite, micrinite, macrinite, resinite, and R{sub max} can be used as the best predictor for the estimation of HGI on multivariable regression (R{sup 2} = 0.81) and also artificial neural network methods (R{sup 2} = 0.95). The ANN based prediction method, as used in this paper, can be further employed as a reliable and accurate method, in the hardgrove grindability index prediction. (author)

    Grindability index of coal is usually determined by Hardgrove Grindability Index (HGI). The correlation between the proximate analysis of Chinese coal and HGI was studied. It was found from statistical analysis that, the higher the moisture and the volatile matter content in coal, the less the HGI will be. On the contrary, the higher the ash and the fixed carbon content in coal, the higher the HGI will be. But the correlation between proximate analysis and HGI in coals is nonlinear. The prediction equation of HGI reported in literature, which is based on proximate analysis of coal and linear regression method, is not correct for coals in China. In this paper, the generalized regression neural network (GRNN) method was used to predict the HGI. A higher precision in the prediction result was obtained through such new method. By this method, the HGI can be estimated indirectly from the proximate analysis of coal when the HGI measurement equipment is not available. 12 refs., 2 figs., 1 tab.

    In recent years, use of artificial neural networks have increased for estimation of Hardgrove grindability index (HGI) of coals. For training of the neural networks, gradient descent methods such as Backpropagaition (BP) method are used frequently. However they originally showed good performance in some non-linearly separable problems, but have a very slow convergence and can get stuck in local minima. In this paper, to overcome the lack of gradient descent methods, a novel particle swarm optimization and artificial neural network was employed for predicting the HGI of Kentucky coals by featuring eight coal parameters. The proposed approach also compared with two kinds of artificial neural network (generalized regression neural network and back propagation neural network). Results indicate that the neural networks - particle swarm optimization method gave the most accurate HGI prediction.

  18. Torrefied Biomass Pellets—Comparing Grindability in Different Laboratory Mills

    Full Text Available The firing and co-firing of biomass in pulverized coal fired power plants around the world is expected to increase in the coming years. Torrefaction may prove to be a suitable way of upgrading biomass for such an application. For transport and storage purposes, the torrefied biomass will tend to be in pellet form. Whilst standard methods for the assessment of the milling characteristics of coal exist, this is not the case for torrefied materials—whether in pellet form or not. The grindability of the fuel directly impacts the overall efficiency of the combustion process and as such it is an important parameter. In the present study, the grindability of different torrefied biomass pellets was tested in three different laboratory mill types; cutting mill (CM, hammer mill (HM and impact mill (IM. The specific grinding energy (SGE required for a defined mass throughput of pellets in each mill was measured and results were compared to other pellet characterization methods (e.g., durability, and hardness as well as the modified Hardgrove Index. Seven different torrefied biomass pellets including willow, pine, beech, poplar, spruce, forest residue and straw were used as feedstock. On average, the particle-size distribution width (across all feedstock was narrowest for the IM (0.41 mm, followed by the HM (0.51 mm and widest for the CM (0.62 mm. Regarding the SGE, the IM consumed on average 8.23 Wh/kg while CM and HM consumed 5.15 and 5.24 Wh/kg, respectively. From the three mills compared in this study, the IM seems better fit for being used in a standardized method that could be developed in the future, e.g., as an ISO standard.

    The effects of macerals, ash, elemental analysis and moisture of wide range of Kentucky coal samples from calorific value of 23.65-34.68 MJ/kg (10,170-14,910 (BTU/lb)) on Hardgrove Grindability Index (HGI) have been investigated by multivariable regression method. Two sets of input: (a) macerals, ash and moisture (b) macerals, elemental analysis and moisture, were used for the estimation of HGI. The least square mathematical method shows that increase of the TiO{sub 2} and Al{sub 2}O{sub 3} contents in coal can decrease HGI. The higher Fe{sub 2}O{sub 3} content in coal can result in higher HGI. With the increase of micrinite and exinite contents in coal, the HGI has been decreased and higher vitrinite content in coal results in higher HGI. The multivariable studies have shown that input set of macerals, elemental analysis and moisture in non-linear condition can be achieved an acceptable correlation, R = 90.38%, versus R = 87.34% for the input set of macerals, ash and moisture. It is predicted that elemental analysis of coal can be a better representative of mineral matters for the prediction of HGI than ash. 16 refs., 9 figs., 2 tabs.

  20. Alternative Evaluation of the grindability of Pozzolanic Materials for Cement Production

    2017-10-01

    An ecological way of reducing CO2 emissions in cement production is the usage of blended cement with an active pozzolan. A part of this issue is the adjustment of granularity of raw materials. This is often achieved by the grinding of the input components. All conventional methods for the evaluation of grindability require a specific grinding instrument. These grinding instruments do not have any other practical use and thus are not very common. This paper focuses on the alternative evaluation of grindability. Inspired by the VTI method used in the coal industry, which uses porcelain laboratory ball mill and compares material based of oversize particles, a new method was created. The first modification in methodology was the use of a planetary mill instead of a porcelain drum mill. Another modification was in the measurement of undersize by means of laser granulometry. This method was then tested on clinker, slag, and recycled glass, which can also be used as an active pozzolan in blended cement. Also, co-milling measurements were made on clinker-pozzolan combinations. These results were then used in the calculation of the grindability index, which can be used for the comparison of properties. The modification of the VTI methodology has a positive impact on the evaluation of grindability, especially with regard to fine particles, thanks to the use of laser granulometry and at the same time it makes use of more a commonly available grinding apparatus

We analysed the effect of the austenitization temperature on the grain size, the amount of retained austenite and percentage of retained austenite in HS3-1-1 steel. Furthermore, the investigations concerned on the efficiency of the keyway broaches during the whole period of operation were carried out. It was found that the value of average roughness parameter increases together with increases in the grinding depth. The investigations also show the influence of tempering conditions on the volume of carbide phases in HS3-1-1 steel.

    Torrefaction, also known as mild pyrolysis, is proven to convert raw biomass into a value-added energy commodity particularly for application in combustion and co-firing systems with improved storage and handling properties. This paper aims to compare the characteristics of Malaysian bituminous coal i.e. Silantek coal with raw and torrefied biomass pellet originated from oil palm frond and fast growing tree species, Leucaena Leucocephala. Biomass samples were initially torrefied at 300 °C for 60 minutes. Resulting torrefied biomass pellets were analysed using a number of standard fuel characterisation analyses i.e. elemental analysis, proximate analysis and calorific content (high heating values) experiments. Investigations on combustion characteristics via dynamic thermogravimetric analysis (TGA), grindability and moisture uptake tests were also performed on the torrefied biomass pellets. Better quality bio-chars were produced as compared to its raw forms and with optimal process conditions, torrefaction may potentially produces a solid fuel with combustion reactivity and porosity equivalent to raw biomass while having compatible energy density and grindability to coal.

    2017-11-01

    Full Text Available This study aimed to investigate the relationship between the surface mechanical properties and the grindability of Ti alloys. Binary Ti alloys containing 5 wt % concentrations of Al, Cr, Sn, or V were prepared using a vacuum arc melting furnace, and their surface properties and grindability were compared to those of commercially pure Ti (cp-Ti. Ti alloys containing Al and Sn had microstructures that consisted of only α phase, while Ti alloys containing Cr and V had lamellar microstructures that consisted of α + β phases. The Vickers microhardness of Ti alloys was increased compared to those of cp-Ti by the solid solution strengthening effect. Among Ti alloys, Ti alloy containing Al had the highest Vickers microhardness. At a low SiC wheel speed of 5000 rpm, the grinding rates of Ti alloys showed an increasing tendency as the hardness values of Ti alloys decreased. At a high SiC wheel speed of 10,000 rpm, the grinding rates of Ti alloys showed an increasing tendency as the tensile strength values increased. The Ti alloy containing Al, which showed the lowest tensile strength, had the lowest grinding rate.

    Grinding of a high volatile bituminous coal was performed in three comminution devices: Raymond Mill (RM), Rolls Crusher (RC) and Ball Mill (BM). The pulverised samples were sieved to obtain four particle size fractions, and temperature-programmed combustion (TPC) was used for the evaluation of their combustion behaviour. In addition, three coals of different hardness and rank were mixed in various proportions in order to compare the combustibility characteristics of the binary coal blends with those of the individual coals. The effect of coal blending on grindability was also studied. It was found that grindability was non-additive especially when coals of very different hardgrove grindability index (HGI) were blended. The combustion studies also suggested that there exists an interaction between individual coals when they are burnt as a blend. (orig.)

    Investigations into the effects of mineral matter content on Hardgrove Grindability Index (HGI) were carried out on some low-rank Turkish coals. Quantitative X-ray diffraction (XRD) analyses were carried out using an interactive data processing system (SIROQUANT(TM)) based on Rietveld interpretation methods. Selective leaching processes were used to determine the water and acid-soluble contents of coal samples. Among the coal seams tested, the HGI values of Elbistan coal samples presented a large range from 39 to 83, whereas Tufanbeyli coal samples ranged from 48 to 69. Treatment of the coal with water, ammonium acetate, and hydrochloric acid showed that a considerable part of the ash-forming inorganic matter occurs in water-soluble, acid-soluble, or ion-exchangeable form. Grindability tests on samples of varied water and acid-soluble content showed a significant effect of water and acid-soluble contents on HGI.

    In this work, a series of coals with different origin and rank were blended and several aspects of the resultant blends were studied. This included determination of the grindability of individual coals and blends by means of the Hardgrove Grindability Index (HGI), and temperature programmed combustion test, which were carried out in a thermogravimetric analyser (TG) coupled to a quadruple mass spectrometer (MS) for evolved gas analysis. Special attention was paid to the combustibility parameters and the NO emissions during blends combustion. It was found that while some coal blends present interaction between the individual coals, others do not. This behaviour was assumed to be due to the differences in coal structure and functional groups composition. 18 refs., 11 figs., 2 tabs.

    The nonlinear back-propagation (BP) neural network models were developed to predict the maximum solid concentration of coal water slurry (CWS) which is a substitute for oil fuel, based on physicochemical properties of 37 typical Chinese coals. The Levenberg-Marquardt algorithm was used to train five BP neural network models with different input factors. The data pretreatment method, learning rate and hidden neuron number were optimized by training models. It is found that the Hardgrove grindability index (HGI), moisture and coalification degree of parent coal are 3 indispensable factors for the prediction of CWS maximum solid concentration. Each BP neural network model gives a more accurate prediction result than the traditional polynomial regression equation. The BP neural network model with 3 input factors of HGI, moisture and oxygen/carbon ratio gives the smallest mean absolute error of 0.40%, which is much lower than that of 1.15% given by the traditional polynomial regression equation.

    The replacement of fossil fuels will lead to an increasing demand for unconventional biofuels. Fuel characterisation to predict combustion properties and facilitate the choice of combustion applications is important to avoid costly and time-consuming mistakes. Traditional methods are developed mainly for coal. Therefore procedures adapted specifically for solid biomass fuels are needed. This work is a survey on approaches for combustion characterisation of biomass developed during the last ten years. Innovative characterisation methods of interest concern: 1) Fuel handling behaviour: grindablility, erosion and abrasion properties. 2) Combustion characterisation: devolatilisation properties (important for ignition and flame stability), char burnout time. 3) Slagging and fouling properties of ash: ash particle formation, ash particle size distribution, ash composition, melting and gasification temperatures, slagging of bottom ash, reducing the risk by mixing with other fuels or using fuel additives and choice of suitable combustion applications for specific fuels. The main conclusions are: 1) a method to measure grindability which takes electric power consumption into account is needed as the Hardgrove Grindability Index used for coal grinding is pointless for biofuels, 2) there is a need to develop convenient low-cost methods to measure slagging and fouling tendencies, devolatilisation kinetics and char burnout for high heating rates found in fluidised beds and powder burners

    Full Text Available Proponents of the efficient market hypothesis believe that active portfolio management is largely wasted effort and unlikely to justify the expenses incurred. Therefore, they advocate a passive investment strategy that makes no attempt to outsmart the market. One common strategy for passive management is indexing where a fund is designed to replicate the performance of a broad-based index of stocks and bonds. Traditionally, indexing was used by institutional investors, but today, the use of index funds proliferated among individual investors. Over the years, both international and domestic index funds have disproportionately outperformed the market more than the actively managed funds have.

    Science.gov (United States)

    The Walkability Index dataset characterizes every Census 2010 block group in the U.S. based on its relative walkability. Walkability depends upon characteristics of the built environment that influence the likelihood of walking being used as a mode of travel. The Walkability Index is based on the EPA's previous data product, the Smart Location Database (SLD). Block group data from the SLD was the only input into the Walkability Index, and consisted of four variables from the SLD weighted in a formula to create the new Walkability Index. This dataset shares the SLD's block group boundary definitions from Census 2010. The methodology describing the process of creating the Walkability Index can be found in the documents located at ftp://newftp.epa.gov/EPADataCommons/OP/WalkabilityIndex.zip.

    This Australian Coal Association Research Program (ACARP) project aimed to demonstrate that the Hardgrove Grindability Index (HGI) coupled with standard Petrographic Analysis can be used to greatly improve the prediction of mill power requirements, mill throughput and product size. The project examined the mill test data from ACIRL's pilot scale vertical spindle mill on 96 coals. A total of 360 mill tests, conducted under a wide range of throughputs, roll pressures and classifier settings, were included into the data set. The mill performance of maceral groups or microlithotypes was assumed to be additive, that is, each maceral group or microlithotype behaved independently and a size fraction of the product PF was the volume weighted sum of the petrographic components of that size fraction. Based on this assumption it was possible to determine the size distribution of the product PF, for a wide range of milling conditions, based solely on petrographic analysis. Microlithotypes were not determined directly but were estimated from the maceral analysis. The size distribution of individual maceral groups or microlithotypes can also be estimated based on developed correlations. Size distribution determined from petrographic analysis proved to be a better estimate than that determined from the HGI. Mill power can be estimated from petrographic analysis, but the HGI was found to be a better predictor of mill power. 19 refs., 4 figs., 1 tab.

  1. Temporal and spatial variations in fly ash quality

    Fly ash quality, both as the amount of petrographically distinguishable carbons and in chemistry, varies in both time and space. Temporal variations are a function of a number of variables. Variables can include variations in the coal blend organic petrography, mineralogy, and chemistry; variations in the pulverization of the coal, both as a function of the coal's Hardgrove grindability index and as a function of the maintenance and settings of the pulverizers; and variations in the operating conditions of the boiler, including changes in the pollution control system. Spatial variation, as an instantaneous measure of fly ash characteristics, should not involve changes in the first two sets of variables listed above. Spatial variations are a function of the gas flow within the boiler and ducts, certain flow conditions leading to a tendency for segregation of the less-dense carbons in one portion of the gas stream.Caution must be applied in sampling fly ash. Samples from a single bin, or series of bins, may not be representative of the whole fly ash, providing a biased view of the nature of the material. Further, it is generally not possible to be certain about variation until the analysis of the ash is complete.

  2. Coal quality assessment - the validity of empirical tests

    2002-09-01

    In the current increasingly environment, long established quality criteria for assessing coals for pulverised fuel-power plants are being re-examined. Reliable tests are needed for evaluating potential fuels. There is a growing consensus that the current standard tests are inadequate and inaccurate, and their ability to predict full-scale performance can be unreliable. Among the tests whose validity has been questioned are the ash fusion temperature, volatile matter, and Hardgrove Grindability Index. This report reviews these and other tests currently in use, examines their validity, and assesses proposed alternatives. It includes tests for assessing a coal's handling and milling behaviour, its combustion characteristics (ignition, flame stability, char reactivity and burnout), and its slagging and fouling propensities. Coal properties affecting the emission of air pollutants (sulphur dioxide, nitrogen oxides, particulates, trace elements and carbon dioxide) and methods for their determination are also covered. It is concluded that the tests will probably be used, for the foreseeable future, primarily to rank unfamiliar coals in comparison with known coals, rather than to give absolute performance parameters. 252 refs., 32 figs., 28 tabs.

    Twenty field-scale tests were conducted in a 28 MW pulverized coal power plant in Healy, Alaska, to examine mill power consumption in relation to coal grind size. The intent in this field-scale study was to verify if grind size truly impacted power consumption by a detectable amount. The regression model developed from the data indicates that grind size does impact mill power consumption, with finer grinds consuming significantly more power than coarser grinds. However, other factors such as coal hardness (i.e. the lower the Hardgrove Grindability Index, or the harder the coal, the higher the power consumption) and mill throughput (i.e., the higher the throughput, the higher the power consumption) had to be included before the impact of grind size could be isolated. It was also observed that combining amperage and flow rate into a single parameter, i.e., specific amperage, hurt modeling. Cost analysis based on the regression model indicate a power savings of $19,972 per year if the coal were ground to 50% passing 76 {mu}m rather than the industry standard of 70% passing 76 {mu}m. The study also demonstrated that size reduction constituted a significant portion of the power consumption.

  4. Low-Rank Coal Grinding Performance Versus Power Plant Performance

    Energy Technology Data Exchange (ETDEWEB)

    Rajive Ganguli; Sukumar Bandopadhyay

    2008-12-31

    The intent of this project was to demonstrate that Alaskan low-rank coal, which is high in volatile content, need not be ground as fine as bituminous coal (typically low in volatile content) for optimum combustion in power plants. The grind or particle size distribution (PSD), which is quantified by percentage of pulverized coal passing 74 microns (200 mesh), affects the pulverizer throughput in power plants. The finer the grind, the lower the throughput. For a power plant to maintain combustion levels, throughput needs to be high. The problem of particle size is compounded for Alaskan coal since it has a low Hardgrove grindability index (HGI); that is, it is difficult to grind. If the thesis of this project is demonstrated, then Alaskan coal need not be ground to the industry standard, thereby alleviating somewhat the low HGI issue (and, hopefully, furthering the salability of Alaskan coal). This project studied the relationship between PSD and power plant efficiency, emissions, and mill power consumption for low-rank high-volatile-content Alaskan coal. The emissions studied were CO, CO{sub 2}, NO{sub x}, SO{sub 2}, and Hg (only two tests). The tested PSD range was 42 to 81 percent passing 76 microns. Within the tested range, there was very little correlation between PSD and power plant efficiency, CO, NO{sub x}, and SO{sub 2}. Hg emissions were very low and, therefore, did not allow comparison between grind sizes. Mill power consumption was lower for coarser grinds.

    1997-08-01

    Using an instrumented laboratory high-pressure grinding rolls mill, the grinding force, gap dimension, mass flow rate and net mill power were measured for size coals and a crystalline quartz. A technique was developed to estimate the compressive stress-strain curves for compression of the materials in the mill plus the effects of elastic decompression. To reconcile the mill power and grinding pressure results, it was necessary to allow for the energy recovery on decompression. No clear correlation was obtained between the form of the stress-strain curves or the variation of specific mill power factor with the Hardgrove grindability index (HGI), although coals with the lowest and highest HGIs (i.e., 44 and 106) gave results significantly different from the other coals. Feeds below 140 mesh (105 {mu}m) flowed more rapidly than coarser feeds and would not build up high grinding pressures. This indicated shearing and fluid-like properties rather than compression as a locked bed. 6 refs., 9 figs., 1 app.

    As part of the activities conducted under the U.S. Hungarian Science and Technology Fund, a total of 39 samples from five coal mines in Hungary were selected for standard coal analyses and major, minor and trace elements analysis. The mine areas sampled were selected to provide a spectrum of coal quality information for comparison with other coal areas in central Europe and worldwide. All of the areas are of major importance in the energy budget of Hungary. The five sample sites contain coal in rocks of Jurassic, Cretaceous, Eocene, Miocene, and Pliocene age. The coals, from four underground and one surface mine, range in rank from high volatile bituminous to lignite B. Most of the coal produced from the mines sampled is used to generate electricity. Some of the power plants that utilize the coals also provide heat for domestic and process usage. The standard coal analysis program is based on tests performed in accordance with standards of the American Society for Testing and Materials (ASTM). Proximate and ultimate analyses were supplemented by determinations of the heating value, equilibrium moisture, forms of sulfur, free-swelling index, ash fusion temperatures (both reducing and oxidizing), apparent specific gravity and Hardgrove Grindability index. The major, minor and trace element analyses were performed in accordance with standardized procedures of the U.S. Geological Survey. The analytical results will be available in the International Coal Quality Data Base of the USGS. The results of the program provide data for comparison with test data from Europe and information of value to potential investors or cooperators in the coal industry of Hungary and Central Europe.

Since index and indexing are remarkably significant in information retrieval, its quality and evaluation and provision of criteria and standards had always been the mainstay of researchers in this field. Given the fact that Indexing is a complex process, offering definitions, principles and methods could be step towards optimal use of the information. The present study, while offering a capsule definition of index, will investigate the indexing evaluation criteria and would follow it up with a definition of indexing. Finally a number of standards in the field of indexing are presented and would make its conclusions.

  3. Mill performance of coal blends

    2005-07-01

    Evaluating the potential performance of coal blends for use as pulverised fuel (PF) in power plants and pulverised coal injection (PCI) into blast furnaces requires knowledge of the size distribution of the organic and mineral matter components of a blend, especially when there are significant differences in the Hardgrove Grindability Index (HGI) of the component coals. The size distribution of the organic matter impacts on combustibility of thermal and PCI coal blends and handleability of PCI coal blends. Petrography techniques were used to examine four size fractions from the PF of single coals and blends to measure the size distribution of maceral groups. For most coals, a good estimate of a blend's size distribution can be made assuming that the size distribution of the individual coals, milled under the same conditions, are added together in the proportions of the blend. The exception is when a very soft coal (HGI 90) is blended with a very hard coal (HGI 35). In this case preferential milling (more reporting to the smaller size fractions) of the softer coal occurred. All coals studied in this project show some sign of preferential grinding of the softer maceral group when the coal was milled individually or in a blend. It is only when there is a large difference in the relative strength of the maceral groups of the coals blended that the preferential milling of a coal in a blend is observed in the size distribution of the blend. The results indicate that the breakage characteristics (change in size reduction per unit of energy) of maceral groups in individual coals do not change when they are blended with other coals. 12 refs., 5 figs., 2 tabs.

    The objective of the research is to improve the efficiency of power station fine coal grinding circuits through the application of modelling and simulation technology. The overall project is expected to complete in 3.5 years as a PhD study program. ACARP funded the first two years (Project C15079) related to the site work conducted at Tarong Power Station, the results of which are presented in this report. A new sampling technique has been developed to collect samples from a fully enclosed vertical spindle ball-race mill and air classifier system and that around the milling circuit. This is crucial in providing reliable data of various streams in the system for model development. Seven surveys on the full scale fine coal grinding operation were conducted at Tarong Power Station using this sampling technique. Extensive sample processing work has been completed. This included size analysis of 217 samples, float-sink tests on 255 samples, and ash content determination on 461 samples. A new float-sink testing technique was developed to process the fine coal samples. Preliminary breakage characterisation using HGI (Hardgrove Grindability Index) tests, DWT (Drop Weight Tester) on single coal particle, and DWT on coal beds of four coal samples was conducted at the JKMRC. This report covers the details of the sampling technique, plant surveys, and preliminary coal breakage characterisation. The observed trends of size distributions, the washability curves, the density - size relation, the density - ash content - size relation, and the correlation among the three breakage characterisation methods are presented and discussed.

    Laboratory crushing experiments were conducted on a range of low to high volatile bituminous coals to investigate the various factors influencing airborne respirable dust generation. Bituminous coal samples from 8 mines (5 U.S. and 3 Polish) were uniformly prepared and processed through a double roll crusher located in a low air velocity wind tunnel. Experimental factors studied included inherent coal seam constituents, specific energy of crushing, product size characteristics, dust cloud electrostatic field, and specific quantity of airborne respirable dust generated. A combination of factors is associated with the generation of airborne respirable dust. One factor involved is the effect of coal rank, described by the inherent moist fuel ratio, on the product size characteristics. However, since coals of high moist fuel ratio (high rank) are generally more extensively cleated, it is suggested that the degree of cleating is directly responsible for the quantity of respirable-sized particles produced in the crushed product material for eastern U.S. coals. This is implied by the relationship of ash content and at least one mineral constituent (pyrite, determined from pyritic sulfur analysis) to the percentage of airborne respirable dust. A clear delineation of coals, based on well-known proximate analysis characteristics, that generate the most respirable dust appears to be possible. It was also shown that the dust-generating characteristics of coals could be reasonably described by both the moist fuel ratio and the Hardgrove Grindability Index (HGI). These results show a clear distinction between eastern and western U.S. coals. However, no consistent distinction for Polish coal was observed.

    To further characterize the Nation's coals, the Penn State Coal Sample Bank and Data Base were expanded to include a total of 1150 coal samples. The Sample Bank includes full-seam channel samples as well as samples of lithotypes, seam benches, and sub-seam sections. To the extent feasible and appropriate basic compositional data were generated for each sample and validated and computerized. These data include: proximate analysis, ultimate analysis, sulfur forms analysis, calorific value, maceral analysis, vitrinite reflectance analysis, ash fusion analysis, free-swelling index determination, Gray-King coke type determination, Hardgrove grindability determination, Vicker's microhardness determination, major and minor element analysis, trace element analysis, and mineral species analysis. During the contract period more than 5000 samples were prepared and distributed. A theoretical and experimental study of the pyrolysis of coal has been completed. The reactivity of chars, produced from all ranks of American coals, has been studied with regard to reactivity to air, CO/sub 2/, H/sub 2/ and steam. Another area research has concerned the catalytic effect of minerals and various cations on the gasification processes. Combustion of chars, low volatile fuels, coal-oil-water-air emulsions and other subjects of research are reported here. The products of this research can be found in 23 DOE Technical Research Reports and 49 published papers. As another mechanism of technology transfer, the results have been conveyed via more than 70 papers presented at a variety of scientific meetings. References to all of these are contained in this report.

    The paper discusses the notion of steps in indexing and reveals that the document-centered approach to indexing is prevalent and argues that the document-centered approach is problematic because it blocks out context-dependent factors in the indexing process. A domain-centered approach to indexing...... is presented as an alternative and the paper discusses how this approach includes a broader range of analyses and how it requires a new set of actions from using this approach; analysis of the domain, users and indexers. The paper concludes that the two-step procedure to indexing is insufficient to explain...... the indexing process and suggests that the domain-centered approach offers a guide for indexers that can help them manage the complexity of indexing....

    To determine glycemic, insulinemic, and satiety indices of 3 types of kefir. This study was divided into 3 phases. In phase 1, 50 g of available carbohydrate from low-fat strawberry kefir or orange kefir was tested, and in phase 2, low-fat plain kefir containing 25 g of available carbohydrates was tested for glycemic index (GI), in both cases compared with an equivalent amount of glucose. In phase 3, 1000-kJ portions of all 3 types of kefirs were compared with white bread with the same energy content to determine the insulinemic index (II) and satiety index (SI) of all 3 kefirs. In all phases, a single-meal, randomized crossover design was performed in which the test meals were given to healthy adults, 5 men and 5 women. The total incremental plasma glucose area under the curve (iAUC) for strawberry, orange, and plain kefirs was significantly lower compared with the respective high-GI control food, which was glucose solution. However, the IIs and SIs of kefir did not differ significantly from the white bread. Kefir is a low- to moderate-GI food; however, its II was high. Although kefir had higher water content, the SI of kefir was not significantly different from white bread.

  19. New Concepts in Indexing *

    Science.gov (United States)

    Shank, Russell

    1965-01-01

    Recent trends in indexing emphasize mechanical, not intellectual, developments. Mechanized operations have produced indexes in depth (1) of information on limited areas of science or (2) utilizing limited parameters for analysis. These indexes may include only citations or both useful data and citations of source literature. Both keyword-in-context and citation indexing seem to be passing the test of the marketplace. Mechanical equipment has also been successfully used to manipulate EAM cards for production of index copy. Information centers are increasingly being used as control devices in narrowly defined subject areas. Authors meet growing pressures to participate in information control work by preparing abstracts of their own articles. Mechanized image systems persist, although large systems are scarce and the many small systems may bring only limited relief for information control and retrieval problems. Experimentation and limited development continue on theory and technique of automatic indexing and abstracting. PMID:14306025

    The glycemic index is a ranking of carbohydrate containing foods. Foods are ranked according to their immediate effect on blood sugar levels. The higher a f ood raises blood sugar, the higher its glycemic index. Scientists published the first index in 1981 when they were researching diet therapy for diabetes. This first list contained 51 foods, and the list has continued to expand, with the most recent official list containing 750 foods. Fruits, grains, dairy products, some vegetables, pastas...

    We measure the efficiency of mergers and acquisitions by putting forward an index (the ‘M&A Index’) based on stochastic frontier analysis. The M&A Index is calculated for each takeover deal and is standardized between 0 and 1. An acquisition with a higher index encompasses higher efficiency. We find that takeover bids with higher M&A Indices are more likely to succeed. Moreover, the M&A Index shows a strong and positive relation with the acquirers’ post-acquisition stock perfo...

    2012-02-01

    In recent years, many of the concerns surrounding the glycemic index have been addressed by methodological studies and clinical trials comparing diets carefully matched for other nutrients. These findings are reviewed together with new observational evidence for the role of the dietary glycemic index in the etiology of cardiovascular disease. The determination and classification of the glycemic index of a food product is now standardized by the International Standards Organization. Systematic studies using isoenergetic single and mixed meals have shown that glycemic index and/or glycemic load are stronger predictors of postprandial glycemia and insulinemia than carbohydrate content alone. In overweight individuals, a diet that combined modestly higher protein and lower glycemic index carbohydrates was the most effective diet for prevention of weight regain. New observational studies have reported increased risks of coronary heart disease associated with higher intakes of carbohydrates from high glycemic index foods. Epidemiological evidence has emerged linking dietary glycemic index to visceral fat and inflammatory disease mortality. There is growing recognition that replacing saturated fat with refined, high glycemic index carbohydrates increases postprandial glycemia and may be detrimental for weight control and predisposition to cardiovascular and inflammatory disease. In contrast, low glycemic index carbohydrates reduce risk.

    We propose three indexing schemes for storing a set S of N points in the plane, each moving along a linear trajectory, so that any query of the following form can be answered quickly: Given a rectangle R and a real value t, report all K points of S that lie inside R at time t. We first present...... an indexing structure that, for any given constant >0, uses O(N/B) disk blocks and answers a query in O((N/B)1/2+ +K/B) I/Os, where B is the block size. It can also report all the points of S that lie inside R during a given time interval. A point can be inserted or deleted, or the trajectory of a point can...... be changed, in O(logB2 N) I/Os. Next, we present a general approach that improves the query time if the queries arrive in chronological order, by allowing the index to evolve over time. We obtain a tradeoff between the query time and the number of times the index needs to be updated as the points move. We...

  5. Effects of coal properties on the production rate of combustion solid residue

    Energy Technology Data Exchange (ETDEWEB)

    Durgun, D. [Catalagzi Thermal Plant, Catalagzi, Zonguldak (Turkey); Genc, A. [Department of Environmental Engineering, Zonguldak Karaelmas University, 67100 Zonguldak (Turkey)

    The production rates of furnace bottom ash in a pulverized coal-fired power plant were monitored for a two-year period and its variations with respect to coal properties were analyzed. The power plant was originally designed to fire the coal sludge generated from a washing process; however, the coal sludge and its mixture with low-rank bituminous coal have been started to be used as the main fuel with time. The results of the hardgrove grindability measurements have shown that the grinding properties of sludge or its mixtures could not be predicted based on proximate analysis (moisture, ash, carbon and volatile contents); it could only be determined by experiments. The production rate of bottom ash in this particular power plant remained relatively insensitive to the high ash and moisture contents and could be estimated almost only by knowing the calorific value of the source coal. The evaluated dependency was linear. (author)

    Full Text Available It is quite impressive the visibility of online publishing compared to offline. Lawrence (2001 computed the percentage increase across 1,494 venues containing at least five offline and five online articles. Results shown an average of 336% more citations to online articles compared to offline articles published in the same venue. If articles published in the same venue are of similar quality, then they concluded that online articles are more highly cited because of their easier access. Thomson Scientific, traditionally concerned with printed journals, announced on November 28, 2005, the launch of Web Citation Index™, the multidisciplinary citation index of scholarly content from institutional and subject-based repositories (http://scientific.thomson. com/press/2005/8298416/. The Web Citation Index from the abstracting and indexing (A&I connects together pre-print articles, institutional repositories and open access (OA journals (Chillingworth, 2005. Basically all research funds are government granted funds, tax payer’s supported and therefore, results should be made freely available to the community. Free online availability facilitates access to research findings, maximizes interaction among research groups, and optimizes efforts and research funds efficiency. Therefore, Ambi-Água is committed to provide free access to its articles. An important aspect of Ambi-Água is the publication and management system of this journal. It uses the Electronic System for Journal Publishing (SEER - http://www.ibict.br/secao.php?cat=SEER. This system was translated and customized by the Brazilian Institute for Science and Technology Information (IBICT based on the software developed by the Public Knowledge Project (Open Journal Systems of the British Columbia University (http://pkp.sfu.ca/ojs/. The big advantage of using this system is that it is compatible with the OAI-PMH protocol for metadata harvesting what greatly promotes published articles

The summaries we support include frequent items, quantiles, and various sketches, all of which are of central importance in massive data analysis......), of a particular attribute of these records. Aggregation queries are especially useful in business intelligence and data analysis applications where users are interested not in the actual records, but some statistics of them. They can also be executed much more efficiently than reporting queries, by embedding...... properly precomputed aggregates into an index. However, reporting and aggregation queries provide only two extremes for exploring the data. Data analysts often need more insight into the data distribution than what those simple aggregates provide, and yet certainly do not want the sheer volume of data...

  8. The great contribution: Index Medicus, Index-Catalogue, and IndexCat.

    Science.gov (United States)

    Greenberg, Stephen J; Gallagher, Patricia E

    2009-04-01

    The systematic indexing of medical literature by the Library of the Surgeon-General's Office (now the National Library of Medicine) has been called "America's greatest contribution to medical knowledge." In the 1870s, the library launched two indexes: the Index Medicus and the Index-Catalogue of the Library of the Surgeon-General's Office. Index Medicus is better remembered today as the forerunner of MEDLINE, but Index Medicus began as the junior partner of what the library saw as its major publication, the Index-Catalogue. However, the Index-Catalogue had been largely overlooked by many medical librarians until 2004, when the National Library of Medicine released IndexCat, the online version of Index-Catalogue. Access to this huge amount of material raised new questions: What was the coverage of the Index-Catalogue? How did it compare and overlap with the Index Medicus? Over 1,000 randomly generated Index Medicus citations were cross-referenced in IndexCat. Inclusion, form, content, authority control, and subject headings were evaluated, revealing that the relationship between the two publications was neither simple nor static through time. In addition, the authors found interesting anomalies that shed light on how medical literature was selected and indexed in "America's greatest contribution to medical knowledge."

    In this paper we explore the logic of now, yesterday, today and tomorrow by combining the semantic approach to indexicality pioneered by Hans Kamp [9] and refined by David Kaplan [10] with hybrid tense logic. We first introduce a special now nominal (our @now corresponds to Kamp’s original now...... operator N) and prove completeness results for both logical and contextual validity. We then add propositional constants to handle yesterday, today and tomorrow; our system correctly treats sentences like “Niels will die yesterday” as contextually unsatisfiable. Building on our completeness results for now......, we prove completeness for the richer language, again for both logical and contextual validity....

  16. Review of Cohesion in Indexing

    Directory of Open Access Journals (Sweden)

    Hasan Ashrafi Rizi

    2007-07-01

    Full Text Available Indexers often disagree on judging terms that best reflect the content of a document. Difference of opinion highlights one of the characteristics of indexing which is indexing cohesion. Also known as consistency, little study of the subject matter has been undertaken in the past few years. However, its importance has been recently acknowledged in effective information retrieval and expansion of access points to the document content. The present paper investigates cohesion in indexing. In addition of presenting the definitions offered by experts, it takes note of the factors influencing indexing cohesion. Methods for measuring cohesion are offered.

  17. Solar index generation and delivery

    Energy Technology Data Exchange (ETDEWEB)

    Lantz, L.J.

    1980-01-01

    The Solar Index, or, more completely defined as the Service Hot Water Solar Index, was conceptualized during the spring of 1978. The purpose was to enhance public awareness to solar energy usability. Basically, the Solar Index represents the percentage of energy that solar would provide in order to heat an 80 gallon service hot water load for a given location and day. The Index is computed by utilizing SOLCOST, a computer program, which also has applications to space heating, cooling, and heat pump systems and which supplies economic analyses for such solar energy systems. The Index is generated for approximately 68 geographic locations in the country on a daily basis. The definition of the Index, how the project came to be, what it is at the present time and a plan for the future are described. Also presented are the models used for the generation of the Index, a discussion of the primary tool of implementation (the SOLCOST program) and future efforts.

When the air temperature is high, the wind increases thermal comfort. But more important for the body is the wind when the air temperature is low. When the air temperature is lower and wind speed higher, the human body is threatening to freeze faster. Cold wind index is used in Canada, USA, Russia (temperature "equivalent" to the facial skin etc., in the weather forecast every day in the cold season. The index can be used and for bioclimatic regionalization, in the form of skin temperature index.

    2014-01-01

    Full Text Available The present paper analyses and revises the latest Democracy Index published by the Economist Intelligence Unit in the United Kingdom. We analyze the changes produced in the index from 2006 to 2011, as well as in the five basic factors that constitute the index: electoral process and pluralism; civil liberties; the functioning of government; political participation; and political culture. The analysis of these factors ?measured by sixty variables? has made it possible to develop a new index, based on the data from 167 countries, and calculate a revised ranking. Countries have been classified into four types: democracies, flawed democracies, mixed systems, and authoritarian/totalitarian regimes. The new index permits a better understanding of the impact of the crisis through variables such as economic growth, human development, quality of life, corruption, and violence.

  15. Wallah. Indexing the new locality

    DEFF Research Database (Denmark)

    Skovse, Astrid Ravn

    This paper aims to add new, empirically based insights to the understanding of the dynamics by which linguistic features come to index locality. It does so through examining the indexicalities of the term wallah among adolescents living in the suburban, multi-ethnic Danish neighborhood Vollsmose....... The paper shows how the term wallah, by being emblematic of the enregistered voices of somewhat competing, locally constructed characterological figures (Agha 2005), comes to serve as an index of highly specific kinds of locality. The data comes from an experimental mapping method tapping into informants...... in a wide range of multi-ethnic settings in Scandinavia – wallah is nevertheless capable of indexing both local and supralocal sociolinguistic scales at once, reflecting the multiscalarity of the “new localities” of globalization (Blommaert 2010). By considering the possibility of features indexing a range...

    2003-01-01

    Authors present an estimation of articulo-trochanteric-distance (ATD) and ATD index in patients with Perthes disease and if there is any correlation between ATD and ATD index and age at the onset, gender, type of treatment, Herring and Stulberg classification. The study population consisted of 242 patients (35 female and 207 male) who had reached skeletal maturity at last follow up. The mean age at the onset of symptoms was 7 years and 4 months. All patients were treated by containment methods (bed rest and traction in abduction, brace, Petri cast, varus osteotomy, Salter osteotomy and shelf operation). ATD was estimated according to the Edgren methods and ATD index was calculated as relation ATD on Perthes site to ATD in normal joint. The late results were classified according to the Stulberg classification. Statistical analysis did not revealed any correlation between the age at the onset, gender and ATD index and ATD during last follow up. Both parameters decreased with poor results according to the Stulberg classifications. ATD index and ATD were statistically significant less after surgical treatment than after non-operative treatment. The same relations were seen between patients with leg length discrepancy (LLD) and without LLD. Patients in Herring group A had statistically significant bigger both parameters than patients in group B, C and patients in Herring group B than C. Articulo-trochanteric-distance and ATD index decreased during follow up and ATD decreased also in normal joint. In our opinion ATD index is a more reliable radiological parameter than ATD. ATD index decreases with bigger necrosis of the femoral head and poor result according to the Stulberg classification. This parameter is an evidence of the dysfunction proximal femoral growth plate in patients with LLD. The most decreased ATD index was observed after surgical treatment. There was no correlation between the age at the onset, gender and ATD index at last follow up.

Novel terms added to the NASA Thesaurus will therefore proceed directly into both the NASA-RECON aerospace information system and its portion of the ESA-Information Retrieval Service, giving users full access to material thus indexed. If a given term appears in the title of a record, it is given special weight. An illustrative graphic representation of the CAI search strategy is presented.

    Full Text Available The main objective of this paper is to bring a model for firm sustainability performance index by applying both classical and Bayesian structural equation modeling (parametric and semi-parametric modeling. Both techniques are considered to the research data collected based on a survey directed to the China, Taiwan, and Malaysia food manufacturing industry. For estimating firm sustainability performance index we consider three main indicators include knowledge management, organizational learning, and business strategy. Based on the both Bayesian and classical methodology, we confirmed that knowledge management and business strategy have significant impact on firm sustainability performance index.

  4. The Callias index formula revisited

    CERN Document Server

    Gesztesy, Fritz

    2016-01-01

    These lecture notes aim at providing a purely analytical and accessible proof of the Callias index formula. In various branches of mathematics (particularly, linear and nonlinear partial differential operators, singular integral operators, etc.) and theoretical physics (e.g., nonrelativistic and relativistic quantum mechanics, condensed matter physics, and quantum field theory), there is much interest in computing Fredholm indices of certain linear partial differential operators. In the late 1970’s, Constantine Callias found a formula for the Fredholm index of a particular first-order differential operator (intimately connected to a supersymmetric Dirac-type operator) additively perturbed by a potential, shedding additional light on the Fedosov-Hörmander Index Theorem. As a byproduct of our proof we also offer a glimpse at special non-Fredholm situations employing a generalized Witten index.

    decomposed than pyrite at the same exposure conditions. Scanning electron microscope (SEM), optical microscope, and X-ray diffraction results indicated that the alterations during microwave treatment were complex. Some intermediate products (e.g. Fe sub ( sub 1 sub - sub x sub ) S) were formed before the sulphides were completely oxidised into hematite (Fe sub 2 O sub 3). Oxidation developed from the surfaces into the cores of the microwaved particles. Metallic particles were also formed during microwave exposure. Lihir gold ore, in which gold was finely disseminated in pyrite and marcasite, was an extremely refractory gold ore. Without pretreatment, only 37 approx 39% of the gold could be extracted with sodium cyanide. However, this was improved after the head ores or floatation concentrates were pretreated by microwave radiation. 74.5 approx 81.2% of the gold was extracted from the microwave treated head ore.

  12. DIDA: Distributed Indexing Dispatched Alignment.

    Directory of Open Access Journals (Sweden)

    Hamid Mohamadi

    Full Text Available One essential application in bioinformatics that is affected by the high-throughput sequencing data deluge is the sequence alignment problem, where nucleotide or amino acid sequences are queried against targets to find regions of close similarity. When queries are too many and/or targets are too large, the alignment process becomes computationally challenging. This is usually addressed by preprocessing techniques, where the queries and/or targets are indexed for easy access while searching for matches. When the target is static, such as in an established reference genome, the cost of indexing is amortized by reusing the generated index. However, when the targets are non-static, such as contigs in the intermediate steps of a de novo assembly process, a new index must be computed for each run. To address such scalability problems, we present DIDA, a novel framework that distributes the indexing and alignment tasks into smaller subtasks over a cluster of compute nodes. It provides a workflow beyond the common practice of embarrassingly parallel implementations. DIDA is a cost-effective, scalable and modular framework for the sequence alignment problem in terms of memory usage and runtime. It can be employed in large-scale alignments to draft genomes and intermediate stages of de novo assembly runs. The DIDA source code, sample files and user manual are available through http://www.bcgsc.ca/platform/bioinfo/software/dida. The software is released under the British Columbia Cancer Agency License (BCCA, and is free for academic use.

    This paper is about combining nondeterminism and probabilities. We study this phenomenon from a domain theoretic point of view. In domain theory, nondeterminism is modeled using the notion of powerdomain, while probability is modeled using the powerdomain of valuations. Those two functors do...... not combine well, as they are. We define the notion of powerdomain of indexed valuations, which can be combined nicely with the usual nondeterministic powerdomain. We show an equational characterization of our construction. Finally we discuss the computational meaning of indexed valuations, and we show how...

    2000-01-01

    In the past, human security has been endangered not only by military threats, but also of resource scarcity, rapid population growth, human rights abuses, and outbreaks of infectious diseases, environmental degradation, pollution, and loss of biodiversity. As a result, the Index of Human Insecurity (IHI) was developed as a classification system that distinguishes the perception of vulnerability and insecurity of different countries. In calculating IHI, the following steps must be used: 1) establishment of complete time series for indicators and countries; 2) standardization of data; and 3) classification of data and calculation of indexes. Indicators used in IHI include the environment, economy, society, and institutions. Furthermore, the indicators used actually define the meaning of human security, compare the relative levels of insecurity, and exclude the vulnerability to natural hazards and income distribution. Comparing the efficacy of using the IHI with Human Development Index, it indicated the transparency of IHI in identifying variability in human security; stronger theoretical base of IHI to both human security and development; and the efficacy of IHI in addressing the issue of perception. To end, policy implications and future applications of IHI indicate that despite the need for constant evaluation of the index, it demonstrates a potential for measuring sustainability, development and human security.

    There has been work on database systems that can retrieve multimedia objects by their content. We are extending this work by using the World Wide Web as source and storage for multimedia objects much like current text search engines do for textual information. A system that can access all types of multimedia objects by their content is a formidable task and improvements are constantly being made to indexing techniques. We have taken an important first step in demonstrating the viability of this technique while laying the groundwork for a larger, more capable system. We have implemented a simple indexing scheme while concentrating on building the infrastructure to support this system. Our system can retrieve references to images on the WWW, index those images, and store those images using spatial access methods. We then use query by example to find a set of images on the WWW that resemble our query image. Due to its design, it is easy to include additional context features, to substitute different indexing schemes, and add other types of multimedia to our system like time sequences, voice and video.

    2010-01-01

    Index Coding has received considerable attention recently motivated in part by applications such as fast video-on-demand and efficient communication in wireless networks and in part by its connection to Network Coding. The basic setting of Index Coding encodes the side-information relation, the problem input, as an undirected graph and the fundamental parameter is the broadcast rate $\\beta$, the average communication cost per bit for sufficiently long messages (i.e. the non-linear vector capacity). Recent nontrivial bounds on $\\beta$ were derived from the study of other Index Coding capacities (e.g. the scalar capacity $\\beta_1$) by Bar-Yossef et al (FOCS'06), Lubetzky and Stav (FOCS'07) and Alon et al (FOCS'08). However, these indirect bounds shed little light on the behavior of $\\beta$ and its exact value remained unknown for \\emph{any graph} where Index Coding is nontrivial. Our main contribution is a hierarchy of linear programs whose solutions trap $\\beta$ between them. This enables a direct information-...

  16. The Biodiversity Informatics Potential Index

    Science.gov (United States)

    2011-01-01

    Background Biodiversity informatics is a relatively new discipline extending computer science in the context of biodiversity data, and its development to date has not been uniform throughout the world. Digitizing effort and capacity building are costly, and ways should be found to prioritize them rationally. The proposed 'Biodiversity Informatics Potential (BIP) Index' seeks to fulfill such a prioritization role. We propose that the potential for biodiversity informatics be assessed through three concepts: (a) the intrinsic biodiversity potential (the biological richness or ecological diversity) of a country; (b) the capacity of the country to generate biodiversity data records; and (c) the availability of technical infrastructure in a country for managing and publishing such records. Methods Broadly, the techniques used to construct the BIP Index were rank correlation, multiple regression analysis, principal components analysis and optimization by linear programming. We built the BIP Index by finding a parsimonious set of country-level human, economic and environmental variables that best predicted the availability of primary biodiversity data accessible through the Global Biodiversity Information Facility (GBIF) network, and constructing an optimized model with these variables. The model was then applied to all countries for which sufficient data existed, to obtain a score for each country. Countries were ranked according to that score. Results Many of the current GBIF participants ranked highly in the BIP Index, although some of them seemed not to have realized their biodiversity informatics potential. The BIP Index attributed low ranking to most non-participant countries; however, a few of them scored highly, suggesting that these would be high-return new participants if encouraged to contribute towards the GBIF mission of free and open access to biodiversity data. Conclusions The BIP Index could potentially help in (a) identifying countries most likely to

    Full Text Available This article investigates MySQL's index capabilities. It begins by reviewing how indexes work, as well as their structure. Next, it reviews indexing features specific to each of the major MySQL data storage engines. This article then examines a broad range of situations in which indexes might help speed up your application. In addition to examining how indexes can be of assistance. In this article we present index usage type: B-trees, hash and bitmap, in order to optimize queries, although MySQL has implemented and indexes spacious R-trees. The index type corresponds to the particular kinds of internal algorithms and datastructures used to implement the index. In MySQL, support for a particular index type is dependent upon the storage engine.

  19. Pricing of temperature index insurance

    2012-01-01

    Full Text Available The aim of this paper is to study pricing of weather insurance contracts based on temperature indices. Three different pricing methods are analysed: the classical burn approach, index modelling and temperature modelling. We take the data from Malaysia as our empirical case. Our results show that there is a significant difference between the burn and index pricing approaches on one hand, and the temperature modelling method on the other. The latter approach is pricing the insurance contract using a seasonal autoregressive time series model for daily temperature variations, and thus provides a precise probabilistic model for the fine structure of temperature evolution. We complement our pricing analysis by an investigation of the profit/loss distribution from the contract, in the perspective of both the insured and the insurer.

    After determined carbohydrate classification, two biscuits products, were evaluated glycemic indexes (GI) and insulin indexes (II). The analytical results showed that the two biscuits were with lower water content and higher lipid than bread. In term of carbohydrate (CHO), the ratio of slow digestible starch (SDS) and resistant starch (RS) to total CHO for two biscuits (> 60%) were higher than bread (18.3%), although the sugar content were also higher. Contrast to GI and II value of glucose (as 100%), the GI and II for bread was 96.2% and 105.2%, respectively. The GIs for both biscuits were lower than 55%, as well as the IIs lower than 73%. It was showed that carbohydrate classification determination is a good way for food industry to produce products with ideal GI value.

    Abstract Background Biodiversity informatics is a relatively new discipline extending computer science in the context of biodiversity data, and its development to date has not been uniform throughout the world. Digitizing effort and capacity building are costly, and ways should be found to prioritize them rationally. The proposed 'Biodiversity Informatics Potential (BIP) Index' seeks to fulfill such a prioritization role. We propose that the potential for biodiversity informatics be assessed ...

    Full Text Available We introduce a tensor sum which is useful for the design and analysis of digit-index permutations (DIPs algorithms. Using this operation we obtain a new high-performance algorithm for the family of DIPs. We discuss an implementation in the applicative language Sisal and show how different choices of parameters yield different DIPs. The efficiency of the special case of digit reversal is illustrated with performance results on a Cray C-90.

    The glycemic index (GI) is a physiological assessment of a food's carbohydrate content through its effect on postprandial blood glucose concentrations. Evidence from trials and observational studies suggests that this physiological classification may have relevance to those chronic Western diseases associated with overconsumption and inactivity leading to central obesity and insulin resistance. The glycemic index classification of foods has been used as a tool to assess potential prevention and treatment strategies for diseases where glycemic control is of importance, such as diabetes. Low GI diets have also been reported to improve the serum lipid profile, reduce C-reactive protein (CRP) concentrations, and aid in weight control. In cross-sectional studies, low GI or glycemic load diets (mean GI multiplied by total carbohydrate) have been associated with higher levels of high-density lipoprotein cholesterol (HDL-C), with reduced CRP concentrations, and, in cohort studies, with decreased risk of developing diabetes and cardiovascular disease. In addition, some case-control and cohort studies have found positive associations between dietary GI and risk of various cancers, including those of the colon, breast, and prostate. Although inconsistencies in the current findings still need to be resolved, sufficient positive evidence, especially with respect to renewed interest in postprandial events, suggests that the glycemic index may have a role to play in the treatment and prevention of chronic diseases.

  6. Deterministic indexing for packed strings

    Bille, Philip; Gørtz, Inge Li; Skjoldjensen, Frederik Rye

    2017-01-01

    Given a string S of length n, the classic string indexing problem is to preprocess S into a compact data structure that supports efficient subsequent pattern queries. In the deterministic variant the goal is to solve the string indexing problem without any randomization (at preprocessing time...... or query time). In the packed variant the strings are stored with several character in a single word, giving us the opportunity to read multiple characters simultaneously. Our main result is a new string index in the deterministic and packed setting. Given a packed string S of length n over an alphabet σ......, we show how to preprocess S in O(n) (deterministic) time and space O(n) such that given a packed pattern string of length m we can support queries in (deterministic) time O (m/α + log m + log log σ), where α = w/log σ is the number of characters packed in a word of size w = θ(log n). Our query time...

    Full Text Available Indexing the etymological lexicographic systems The main problems and directions for the development of the etymological lexicographic systems in the digital environment are studied. The formal conceptual model of the lexicographic system for fundamental academic Etymological Dictionary of the Ukrainian Language (EDUL is developed. The lexicographic structure of the EDUL individual elements are developed and described. The EDUL metalanguage was studied and described. The formal model and technology of the EDUL parsing are worked out. That made it possible to convert automatically the EDUL text into the lexicographic database, which corresponds to the conceptual model of the lexicographic system. The conceptual foundations of instrumental tool to form the etymological dictionaries are developed to create the Virtual Lexicographic Laboratory «Etymological Dictionary of the Ukrainian Language», which was implemented with a modern approach to the real lexicographic array of the EDUL. That allowed to form the database of the EDUL multilingual index (about 250 languages in the automatic mode. This index is a basis of the seventh (final volume of the EDUL. The possibility of applying the developed models to other etymological dictionaries are studied. The conceptual foundations for integration of the etymological lexicographic systems are discussed.

  8. Experimental comparison between speech transmission index, rapid speech transmission index, and speech intelligibility index.

    Larm, Petra; Hongisto, Valtteri

    2006-02-01

    During the acoustical design of, e.g., auditoria or open-plan offices, it is important to know how speech can be perceived in various parts of the room. Different objective methods have been developed to measure and predict speech intelligibility, and these have been extensively used in various spaces. In this study, two such methods were compared, the speech transmission index (STI) and the speech intelligibility index (SII). Also the simplification of the STI, the room acoustics speech transmission index (RASTI), was considered. These quantities are all based on determining an apparent speech-to-noise ratio on selected frequency bands and summing them using a specific weighting. For comparison, some data were needed on the possible differences of these methods resulting from the calculation scheme and also measuring equipment. Their prediction accuracy was also of interest. Measurements were made in a laboratory having adjustable noise level and absorption, and in a real auditorium. It was found that the measurement equipment, especially the selection of the loudspeaker, can greatly affect the accuracy of the results. The prediction accuracy of the RASTI was found acceptable, if the input values for the prediction are accurately known, even though the studied space was not ideally diffuse.

    The pioneering work of Charles W. Frederick and George W. Morey on the design by Frederick of an "ideal photographic lens" using hypothetical glasses, and the subsequent discovery and development of rare-element borate glasses by Morey, has been resumed at Eastman Kodak. New ultra-high index, low dispersion crown glasses and companion flint glasses have been developed, based on the needs dictated by lens design studies for novel fast cine' and still camera lenses. These new glasses reduce the number of elements required in a lens while maintaining or improving lens performance. Composition studies leading to these new glasses will be discussed.

    The Net Reclassification Index (NRI) is a very popular measure for evaluating the improvement in prediction performance gained by adding a marker to a set of baseline predictors. However, the statistical properties of this novel measure have not been explored in depth. We demonstrate the alarming...... marker is proven to erroneously yield a positive NRI. Some insight into this phenomenon is provided. Since large values for the NRI statistic may simply be due to use of poorly fitting risk models, we suggest caution in using the NRI as the basis for marker evaluation.

    Full Text Available Bibliometric analyses based on citations are most often at the forefront where scientific publications are concerned. A fact often neglected is that the visibility and availability of scientific publications are basic prerequisites for future reading, citation and influence. Journal visibility can be significantly improved by providing open access and availability through popular online databases. In this study, we investigated 112 mapping science journals to determine the visibility of scientific publications in a smaller interdisciplinary field. In addition to other data, we collected data on open access, indexing, subject areas within the Web of Science and Scopus bibliographic databases and the number of journals in these databases. The coverage of mapping science journals in 14 bibliographic databases was analyzed. Only 11% of the titles from the journals analyzed were indexed in 10 or more databases. Google Scholar, Scopus, Bibliotheca Cartographica and GEOBASE include most mapping science journals, while only 19 are included in Web of Science. A comparison indicates more thorough coverage of an individual journal in Web of Science than in Scopus. Only a few mapping science journals appear in the Directory of Open Access Journals, despite the large number of open access mapping science journals available. Adding subject categories within databases does not facilitate finding mapping science journals, which are dispersed among numerous, mostly inadequate categories in the Web of Science and Scopus databases.

  12. Environmental/Biomedical Terminology Index

    The Information Center Complex (ICC), a centrally administered group of information centers, provides information support to environmental and biomedical research groups and others within and outside Oak Ridge National Laboratory. In-house data base building and development of specialized document collections are important elements of the ongoing activities of these centers. ICC groups must be concerned with language which will adequately classify and insure retrievability of document records. Language control problems are compounded when the complexity of modern scientific problem solving demands an interdisciplinary approach. Although there are several word lists, indexes, and thesauri specific to various scientific disciplines usually grouped as Environmental Sciences, no single generally recognized authority can be used as a guide to the terminology of all environmental science. If biomedical terminology for the description of research on environmental effects is also needed, the problem becomes even more complex. The building of a word list which can be used as a general guide to the environmental/biomedical sciences has been a continuing activity of the Information Center Complex. This activity resulted in the publication of the Environmental Biomedical Terminology Index (EBTI).

  13. Glycemic index in sport nutrition.

    Mondazzi, Luca; Arcelli, Enrico

    2009-08-01

    Carbohydrates (CHO) can be classified on the basis of their glycemic index (GI), and the use of this classification has been increasingly supported by science. Because of its impact on blood glucose and insulin responses following the ingestion of CHO foods, the GI has been studied in many fields of medicine, including sport nutrition. As a new tool in sport nutrition, glycemic index manipulation has been evaluated to improve the first and second phases of glycogen recovery, glycogen load, and exercise metabolism, including control of rebound hypoglycemia and, it is interesting to note, stimulation of lipid oxidation for longer availability of glucose sources during endurance exercise. Although attractive, the use of GI in sport nutrition has received only partial support from available experimental evidence. At the biochemical level, consistent evidence has been attained to suggest that GI manipulation can determine variations in adipocyte lipolysis, plasma free fatty acids levels, and lipid and CHO oxidation rates during exercise. However, when the effects of GI manipulation have been assessed at the functional level, the results have been inconsistent, with evidence of improved exercise performance in some studies, but not in many others. The purpose of the current article is to review the effects and limits of GI manipulation in sport nutrition, and to propose an overall strategy for its application.

    2005-10-01

    A new low-loss high-index-contrast photonics platform has been developed for integrated optics and microwave photonics. The platform consists of a material system that has an index contrast that is adjustable from 0 to 25% and which is processed using conventional CMOS tools. The platform allows one to four orders of magnitude reduction in the size of optical components compared with conventional planar technologies. As an example, meter long path lengths occupy coils that are millimeters in diameter. Microwave photonic building blocks that are enabled include large bit count programmable delay lines for beam steering and shaping that fit in less than a square centimeter and which have delays controllable from 5 fsec to 10 nsec. Also enabled are arrays of high order tunable filters, a hundred micrometers in size, having linewidths ranging from tens of MHz to tens of GHz. These filters can be tuned over several hundred GHz, and when placed in Vernier architectures can be tuned across the C band (5 THz). An optical chip typically consists of dozens of optical elements. Each element is placed in its own micro-control loop that consists of a thin film heater for thermo-optic control and a thermistor for electronic feedback. The micro-control loops impart intelligence to the optical chip.

    Full Text Available Abstract Background: Indexing is a crucial step in any information retrieval system. In MEDLINE, a widely used database of the biomedical literature, the indexing process involves the selection of Medical Subject Headings in order to describe the subject matter of articles. The need for automatic tools to assist MEDLINE indexers in this task is growing with the increasing number of publications being added to MEDLINE. Methods: In this paper, we describe the use and the customization of Inductive Logic Programming (ILP to infer indexing rules that may be used to produce automatic indexing recommendations for MEDLINE indexers. Results: Our results show that this original ILP-based approach outperforms manual rules when they exist. In addition, the use of ILP rules also improves the overall performance of the Medical Text Indexer (MTI, a system producing automatic indexing recommendations for MEDLINE. Conclusion: We expect the sets of ILP rules obtained in this experiment to be integrated into MTI.

    Wu, Chao-Cheng; Chang, Chein-I.

    2009-05-01

    Pixel Purity Index (PPI) has been widely used in endmember extraction. While it is available in ENVI software there are several interesting issues arising in its implementation. This paper re-invents the wheel by re-visiting the design rationale of the PPI and re-designing algorithms to implement PPI. More specifically, it develops the so-called Causal PPI (CPPI) which implements the PPI in a causal manner in the sense that the information used for data processing is only up to the data sample currently being visited. If the time required for computer processing is negligible, the CPPI actually becomes a real time PPI. The proposed CPPI can be implemented automatically and resolves the main issue of requiring human intervention to determine parameters.

    This study develops two sub-indexes of port classification and capacity, and combines cases of these two sub-indexes into various types in order to find a proper port hub index. The paper demonstrates how different types of port hub index are useful measurements for evaluating outputs and inputs of container ports. In a case analysis we show that the indexes of period variables and lagged variables have more explanatory power with regard to changes of port throughputs and high correlation with inputs.

  1. Possible values of UV index in Serbia

    Directory of Open Access Journals (Sweden)

    Letić Milorad

    2008-01-01

    Full Text Available INTRODUCTION UV Index is an indicator of human exposure to solar ultraviolet (UV rays. The numerical values of the UV Index range from 1-11 and above. There are three levels of protection against UV radiation; low values of the UV Index - protection is not required, medium values of the UV Index - protection is recommended and high values of the UV Index - protection is obligatory. The value of the UV Index primarily depends on the elevation of the sun and total ozone column. OBJECTIVE The aim of the study is to determine the intervals of possible maximal annual values of the UV Index in Serbia in order to determine the necessary level of protection in a simple manner. METHOD For maximal and minimal expected values of total column ozone and for maximal elevation of the sun, the value of the UV Index was determined for each month in the Northern and Southern parts of Serbia. These values were compared with the forecast of the UV Index. RESULTS Maximal clear sky values of the UV Index in Serbia for altitudes up to 500m in May, June, July and August can be 9 or even 10, and not less than 5 or 6. During November, December, January and February the UV Index can be 4 at most. During March, April, September and October the expected values of the UV Index are maximally 7 and not less than 3. The forecast of the UV Index is within these limits in 98% of comparisons. CONCLUSION The described method of determination of possible UV Index values showed a high agreement with forecasts. The obtained results can be used for general recommendations in the protection against UV radiation.

    2009-01-01

    Full Text Available Polycarbonates and polythiourethanes are the most popular materials in use today, for optical applications. Polycarbonates are of two types which fall in the category of low refractive index and medium refractive index. The present paper describes the conversion of low refractive index polycarbonates into high refractive index material by the use of a high refractive index monomer, polythiol, as an additive. Novel polycarbonates, where the properties of refractive index and Abbe number can be tailor made, have been obtained. Thermal studies and refractive index determination indicate the formation of a new polymer with improved properties and suitable for optical applications.

  4. Approximate String Matching with Compressed Indexes

    Directory of Open Access Journals (Sweden)

    Pedro Morales

    2009-09-01

    Full Text Available A compressed full-text self-index for a text T is a data structure requiring reduced space and able to search for patterns P in T. It can also reproduce any substring of T, thus actually replacing T. Despite the recent explosion of interest on compressed indexes, there has not been much progress on functionalities beyond the basic exact search. In this paper we focus on indexed approximate string matching (ASM, which is of great interest, say, in bioinformatics. We study ASM algorithms for Lempel-Ziv compressed indexes and for compressed suffix trees/arrays. Most compressed self-indexes belong to one of these classes. We start by adapting the classical method of partitioning into exact search to self-indexes, and optimize it over a representative of either class of self-index. Then, we show that a Lempel- Ziv index can be seen as an extension of the classical q-samples index. We give new insights on this type of index, which can be of independent interest, and then apply them to a Lempel- Ziv index. Finally, we improve hierarchical verification, a successful technique for sequential searching, so as to extend the matches of pattern pieces to the left or right. Most compressed suffix trees/arrays support the required bidirectionality, thus enabling the implementation of the improved technique. In turn, the improved verification largely reduces the accesses to the text, which are expensive in self-indexes. We show experimentally that our algorithms are competitive and provide useful space-time tradeoffs compared to classical indexes.

The l-index is compared with degree (a local measure), betweenness and Eigenvector centralities (two global measures) in the case of a biological network (Yeast interaction protein-protein network) and a linguistic network (Moby Thesaurus II). In both networks, the l-index has a poor correlation with betweenness but correlates with degree and Eigenvector centralities. Although being local, the l-index carries more information about its neighbors than degree centrality. Also, it requires much less time to compute when compared with Eigenvector centrality. Results show that the l-index produces better results than degree and Eigenvector centrality for ranking purposes.

    2016-01-01

    One of the determining factors of the quality of Web search engines is the size of their index. In addition to its influence on search result quality, the size of the indexed Web can also tell us something about which parts of the WWW are directly accessible to the everyday user. We propose a novel...... method of estimating the size of a Web search engine’s index by extrapolating from document frequencies of words observed in a large static corpus of Web pages. In addition, we provide a unique longitudinal perspective on the size of Google and Bing’s indices over a nine-year period, from March 2006...... until January 2015. We find that index size estimates of these two search engines tend to vary dramatically over time, with Google generally possessing a larger index than Bing. This result raises doubts about the reliability of previous one-off estimates of the size of the indexed Web. We find...

  11. Risk weighted alpha index – analysis of the ASX50 index

    Directory of Open Access Journals (Sweden)

    Nipun Agarwal

    2013-12-01

    Full Text Available Major stock indexes are developed on the market capitalization or price weighted indexation method. The Australian Stock Exchange 50 (ASX50 index is a market capitalization index of the top 50 Australian stocks. Fundamental indexation, equal weighted index and risk weighted index methods have recently been developed as an alternative to the market cap and price indexes. However, empirical studies do not conclusively prove if these alternate methods are more efficient to the existing market cap or price weighted methods. Also, the fundamental index method provides a higher alpha, while the risk weighted index methods focus on risk reduction through diversification. There is a gap to develop another passive indexation method in order to provide the investor a higher return (alpha and lower volatility. This paper re-weights the ASX50 index using the risk weighted alpha method and provides higher weight to stocks that have increasing returns and lower volatility. The empirical study for ASX50 index from 2002-2012 is undertaken and results show that the risk weighted alpha method provides higher return and has lower systematic risk than the ASX50 index.

    Full Text Available Abstract The study provides the rationale, history and current status of the Index Medicus for the World Health Organization Eastern Mediterranean Region. The Index is unique in combining the geographic coverage of peer-reviewed health and biomedical journals (408 titles from the 22 countries of the Region. Compiling and publishing the Index coupled with a document delivery service is an integral part of the WHO Regional Office's knowledge management and sharing programme. In this paper, bibliometric indicators are presented to demonstrate the distribution of journals, articles, languages, subjects and authors as well as availability in printed and electronic formats. Two countries in the Region (Egypt and Pakistan contribute over 50% of the articles in the Index. About 90% of the articles are published in English. Epidemiology articles represent 8% of the entire Index. 15% of the journals in the Index are also indexed in MEDLINE, while 7% are indexed in EMBASE. Future developments of the Index will include covering more journals and adding other types of health and biomedical literature, including reports, theses, books and current research. The challenges and lessons learnt are discussed.

    Full Text Available Purpose: This paper combines a synthetic index system by the variables and evaluates China’s financial safety through the change of indexes in a comprehensive way. First of all, it builds the financial industry evaluation index system composed of 25indicators in terms of the operation of the financial industry and external economic environment and particularly takes into consideration factors which might trigger liquidity risks such as off-balance-sheet business, interbank business and shadow banking; then it selects 10 indicators to conduct empirical analysis and identifies the indicator weight through principal component analysis; finally it combines the financial safety indexes through the linear weighted comprehensive evaluation model.Design/methodology/approach: Synthesis of indexes is made by constructing a proper comprehensive evaluation mathematical model, integrating a number of evaluation indexes into one comprehensive evaluation index and then obtaining corresponding comprehensive evaluation results. In this paper, it selects 10 indexes to conduct empirical analysis and identifies the index weight through principal component analysis; finally it combines the financial safety indexes through the linear weighted comprehensive evaluation model. Principal component analysis (PCA is a statistical procedure that uses an orthogonal transformation to convert a set of observations of possibly correlated variables into a set of values of linearly uncorrelated variables called principal components. PCA was invented in 1901 and was later independently developed (and named by Harold Hotelling in the 1930s.Findings: From 2003 to 2013 China’s financial safety indexes fluctuated. From 2003 to 2007 indexes rose, which indicates China’s financial safety status gradually improved; from 2007 to 2009 indexes declined, which indicates due to the impact of subprime crisis, China’s financial safety status took a turn for the worse; from 2009 to 2012

    Full Text Available Ecological security of the state – is a complex and multifaceted category that requires deep study. A comprehensive assessment of environmental security in terms of national security in Ukraine is not exercised. The paper summarizes the theoretical aspects of ecological safety of Ukraine and its components, contains the analysis of environmental safety indexes compiled by international organizations, including the Commission on Sustainable Development UN, the International Institute for Sustainable Development (IISD, the Scientific Committee on Problems of the Environment (SCOPE, Yale University. Analyses of such indexes as Environmental Sustainability Index, Environmental Performance Index, Human Development Index, Environmental Vulnerability Index, Enabling Environment Index had shown that despite all of them represent the level of ecological security, there is a lack of adapted for Ukraine method to assess domestic ecological situation and to compare it with global tendencies. On the basis of statistical data, a concept of evaluation of Environmental Safety Index (ESfIof Ukraine is proposed for subsequent adequate science-based assessment of the current level of ecological situation in Ukraine in comparison with other countries. Its main feature is that it takes into account in addition to the most important environmental indicators also economic and demographic indicators as threats/risks components. The rating of more than 150 countries according to ESfI is evaluated.

    The glycemic index concept owes much to the dietary fiber hypothesis that fiber would reduce the rate of nutrient absorption and increase the value of carbohydrate foods in the maintenance of health and treatment of disease. However, properties and components of food other than its fiber content contribute to the glycemic and endocrine responses postprandially. The aim of the glycemic index classification of foods was therefore to assist in the physiological classification of carbohydrate foods which, it was hoped, would be of relevance in the prevention and treatment of chronic diseases such as diabetes. Over the past two decades low glycemic index diets have been reported to improve glycemic control in diabetic subjects, to reduce serum lipids in hyperlipidemic subjects and possibly to aid in weight control. In large cohort studies, low glycemic index or glycemic load diets (glycemic index multiplied by total carbohydrate) have also been associated with higher levels of high-density lipoprotein cholesterol, reduced C-reactive protein concentrations and with a decreased risk of developing diabetes and cardiovascular disease. More recently, some case-control and cohort studies have also found positive associations between the dietary glycemic index and the risk of colon, breast and other cancers. While the glycemic index concept continues to be debated and there remain inconsistencies in the data, sufficient positive findings have emerged to suggest that the glycemic index is an aspect of diet of potential importance in the treatment and prevention of chronic diseases.

    2004-01-01

    Full Text Available The plasticity index of clayey soils has been known as a good indicator for many soil parameters. This paper describes how the plasticity index of clays correlates well with the friction coefficient on certain concrete interfaces. Interface direct shear tests were carried out on undisturbed clay samples. The test specimens were normally loaded to simulate the lateral stress at its field condition, and later sheared along a concrete interface. The ratio between the shear stress and the normal stress is termed as the friction coefficient. It appeared that for a certain interface a unique relation between plasticity index and the friction coefficient could be established. Thus, knowing the plasticity index of a clay layer we could determine its adhesion or skin resistance to an embedded pile surface. Abstract in Bahasa Indonesia : Index plastisitas tanah kelempungan mempunyai pengaruh terhadap sifat-sifat tanah tersebut, dan telah dipakai untuk menentukan beberapa parameter tanah. Penelitian dalam tulisan ini berupaya mengetahui pengaruh index plastisitas tanah kelempungan terhadap koefisien geseknya ke permukaan suatu bahan beton. Percobaan dilakukan dalam alat geser langsung (direct shear. Spesimen uji tanah digeserkan ke atas permukaan suatu bahan beton setelah dibebani sesuai dengan tegangan lateral yang pernah diterimanya. Koefisien gesek didefinisikan sebagai rasio antara tegangan geser serta tegangan lateral ini. Ternyata untuk sesuatu macam permukaan bahan didapat hubungan yang cukup unik antara koefisien gesek dengan index plastisitas tanah. Untuk sesuatu lapisan tanah kelempungan dengan index plastisitas tertentu dapat ditentukan besarnya hambatan lekat tanahnya pada permukaan suatu tiang pondasi yang ditahannya.

    The development of transparent materials is closed to optoelectronic technology. It plays an increasingly important role in various fields. It is not only widely used in optical lens, optical element, optical fiber grating, optoelectronics, but also widely used in the building material, pharmaceutical industry with vessel, aircraft windshield and daily wear glasses.Regard of solving the problem of refractive index measurement in optical transparent materials. We proposed that using the polychromatic confocal method to measuring the refractive index of transparent materials. In this article, we describes the principle of polychromatic confocal method for measuring the refractive index of glass,and sketched the optical system and its optimization. Then we establish the measurement model of the refractive index, and set up the experimental system. In this way, the refractive index of the glass has been calibrated for refractive index experiment. Due to the error in the experimental process, we manipulated the experiment data to compensate the refractive index measurement formula. The experiment taking the quartz glass for instance. The measurement accuracy of the refractive index of the glass is +/-1.8×10-5. This method is more practical and accurate, especially suitable for non-contact measurement occasions, which environmental requirements is not high. Environmental requirements are not high, the ordinary glass production line up to the ambient temperature can be fully adapted. There is no need for the color of the measured object that you can measure the white and a variety of colored glass.

  18. Decomposing the misery index: A dynamic approach

    Directory of Open Access Journals (Sweden)

    Ivan K. Cohen

    2014-12-01

    Full Text Available The misery index (the unweighted sum of unemployment and inflation rates was probably the first attempt to develop a single statistic to measure the level of a population’s economic malaise. In this letter, we develop a dynamic approach to decompose the misery index using two basic relations of modern macroeconomics: the expectations-augmented Phillips curve and Okun’s law. Our reformulation of the misery index is closer in spirit to Okun’s idea. However, we are able to offer an improved version of the index, mainly based on output and unemployment. Specifically, this new Okun’s index measures the level of economic discomfort as a function of three key factors: (1 the misery index in the previous period; (2 the output gap in growth rate terms; and (3 cyclical unemployment. This dynamic approach differs substantially from the standard one utilised to develop the misery index, and allow us to obtain an index with five main interesting features: (1 it focuses on output, unemployment and inflation; (2 it considers only objective variables; (3 it allows a distinction between short-run and long-run phenomena; (4 it places more importance on output and unemployment rather than inflation; and (5 it weights recessions more than expansions.

    Full Text Available Consumer confidence index is a national indicator that suggest about current and future expectations of the economic conditions. With consumer confidence index, it is aimed to determine the trends and expectations of consumers according to their general economic situation, employment opportunities, their financial situations and developments in the markets. Another parameter is also the Human Development Index (HDI. This index is an indicator that examines the development of countries both economically and socially. Countries are sorted by these two indices and are considered as basic parameters in international platforms. The purpose of this study is to group the selected countries according to the consumer confidence index and reveal the features of the groups and then determine the position of the grouped countries with the Human Development Index. According to the results of cluster analysis, it is shown that India, China, Sweden and USA have the highest total consumer confidence index, employment, expectation and investment index

    2003-01-01

    With the proliferation of mobile computing, the ability to index efficiently the movements of mobile objects becomes important. Objects are typically seen as moving in two-dimensional (x,y) space, which means that their movements across time may be embedded in the three-dimensional (x,y,t) space...... is to reduce movements to occur in one spatial dimension. As a consequence, the movement data becomes two-dimensional (x,t). The advantages of considering such lower-dimensional trajectories are the reduced overall size of the data and the lower-dimensional indexing challenge. Since off-the-shelf database...... management systems typically do not offer higher-dimensional indexing, this reduction in dimensionality allows us to use such DBM- Ses to store and index trajectories. Moreover, we argue that, given the right circumstances, indexing these dimensionality-reduced trajectories can be more efficient than using...

Presently (2011), the index velocity method is being used to compute discharge records for approximately 470 gaging stations operated and maintained by the U.S. Geological Survey. The purpose of this report is to document and describe techniques for computing discharge records using the index velocity method. Computing discharge using the index velocity method differs from the traditional stage-discharge method by separating velocity and area into two ratings—the index velocity rating and the stage-area rating. The outputs from each of these ratings, mean channel velocity (V) and cross-sectional area (A), are then multiplied together to compute a discharge. For the index velocity method, V is a function of such parameters as streamwise velocity, stage, cross-stream velocity, and velocity head, and A is a function of stage and cross-section shape. The index velocity method can be used at locations where stage-discharge methods are used, but it is especially appropriate when more than one specific discharge can be measured for a specific stage. After the ADVM is selected, installed, and configured, the stage-area rating and the index velocity rating must be developed. A standard cross section is identified and surveyed in order to develop the stage-area rating. The standard cross section should be surveyed every year for the first 3 years of operation and thereafter at a lesser frequency, depending on the susceptibility of the cross section to change. Periodic measurements of discharge are used to calibrate and validate the index rating for the range of conditions experienced at the gaging station. Data from discharge measurements, ADVMs, and stage sensors are compiled for index-rating analysis. Index ratings are developed by means of regression

    We propose a simple real-time index of global human-induced warming and assess its robustness to uncertainties in climate forcing and short-term climate fluctuations. This index provides improved scientific context for temperature stabilisation targets and has the potential to decrease the volatility of climate policy. We quantify uncertainties arising from temperature observations, climate radiative forcings, internal variability and the model response. Our index and the associated rate of human-induced warming is compatible with a range of other more sophisticated methods to estimate the human contribution to observed global temperature change.

    Full Text Available Cephalic index is the ratio of head’s breadth to length, which reflects the cranial dimensions and is an important parameter in anthropometry. Cephalic index is also known as cranial index and was defined by Swedish professor of anatomy Anders Retzius. It is useful to differentiate different types of crania belonging to different races, gender, age, geographical zones, tradition and nutrition, etc. AIMS To estimate foetal cephalic index by ultrasonography, to classify foetal heads as per international categories and to know the frequent head types in second and third trimesters of pregnancy. MATERIAL AND METHODS This prospective cross-sectional study included 100 normal singleton pregnant women with foetuses in the duration 12 to 40 weeks of gestational age. By ultrasonography, foetal head breadth and length was measured. Cephalic index was calculated by Breadth/Length X 100 and all the heads were classified as per international categories. RESULTS Of the total 100 foetal heads in the gestational age of 12 to 40 weeks, the mean cephalic index was 78.95±03.01. Mean biparietal diameter was 68.04±22.26. Mean occipitofrontal diameter was 86.38±28.61. According to cephalic index value 51% mesocephalic, 38% brachycephalic, 10% dolichocephalic and 1% hyperbrachycephalic heads were noticed. A mean cephalic index of 80 at 12-16 weeks, 78.48 at 36-40 weeks and a constant cephalic index of 78 to 79 was observed between 16-36 weeks. CONCLUSIONS The mean cephalic index in the present study was 78.95 and is of mesocephalic phenotype in our study. It is the most frequent head type noticed. A linear correlation was observed between gestational age versus biparietal diameter and occipitofrontal diameter. No linear relationship was seen between gestational age and cephalic index. Brachycephalic heads at 12-16 weeks, mesocephalic heads at 36-40 weeks and a constant cephalic index of 78 to 79 was noticed from 16 to 36 weeks of gestation.

    We show that specializations of the 4d N=2 superconformal index labeled by an integer N is given by Tr ℳ N where ℳ is the Kontsevich-Soibelman monodromy operator for BPS states on the Coulomb branch. We provide evidence that the states enumerated by these limits of the index lead to a family of 2d chiral algebras A_N . This generalizes the recent results for the N = -1 case which corresponds to the Schur limit of the superconformal index. We show that this specialization of the index leads to the same integrand as that of the elliptic genus of compactification of the superconformal theory on S 2 × T 2 where we turn on 1/2N units of U(1) r flux on S 2.

  15. The refractive index of relic gravitons

    CERN Document Server

    Giovannini, Massimo

    2016-01-01

    The dynamical evolution of the refractive index of the tensor modes of the geometry produces a specific class of power spectra characterized by a blue (i.e. slightly increasing) slope which is directly determined by the competition of the slow-roll parameter and of the rate of variation of the refractive index. Throughout the conventional stages of the inflationary and post-inflationary evolution, the microwave background anisotropies measurements, the pulsar timing limits and the big-bang nucleosythesis constraints set stringent bounds on the refractive index and on its rate of variation. Within the physically allowed region of the parameter space the cosmic background of relic gravitons leads to a potentially large signal for the ground based detectors (in their advanced version) and for the proposed space-borne interferometers. Conversely, the lack of direct detection of the signal will set a qualitatively new bound on the dynamical variation of the refractive index.

    With the indexing of imaginative literature included in an expanding number of bibliographic databases, the overall representation of this kind of literature has definitely been improved. Still, in terms of information retrieval and being able to judge the relevance of the titles, it seems...... that the usefulness of classification and indexing alike are still being restricted by some old romantic and objectivistic, or even positivistic, ideas and ideals. In order to argue that point the paper firstly re-examines the classification of imaginative literature in early editions of the Dewey Decimal......

  2. Identifying Critical States through the Relevance Index

    Directory of Open Access Journals (Sweden)

    Andrea Roli

    2017-02-01

    Full Text Available The identification of critical states is a major task in complex systems, and the availability of measures to detect such conditions is of utmost importance. In general, criticality refers to the existence of two qualitatively different behaviors that the same system can exhibit, depending on the values of some parameters. In this paper, we show that the relevance index may be effectively used to identify critical states in complex systems. The relevance index was originally developed to identify relevant sets of variables in dynamical systems, but in this paper, we show that it is also able to capture features of criticality. The index is applied to two prominent examples showing slightly different meanings of criticality, namely the Ising model and random Boolean networks. Results show that this index is maximized at critical states and is robust with respect to system size and sampling effort. It can therefore be used to detect criticality.

    We report the effect of changes in the corneal hydration on the refractive index of the cornea. Using optical coherence tomography (OCT), the geometrical thickness and the group refractive index of the bovine cornea were derived simultaneously as the corneal hydration was varied. The corneal hydration was then calculated from the corneal thickness. The group refractive index of the cornea increased non-linearly as the cornea dehydrated. In addition, a simple mathematical model was developed, based on the assumption that changes in corneal hydration occur only in the interfibrilar space with constant water content within the collagen fibrils. Good agreement between the experimental results and the mathematical model supports the assumption. The results also demonstrate that the measurement of refractive index is a quantitative indicator of corneal hydration.

  13. Aggregated Indexing of Biomedical Time Series Data.

    2012-09-01

    Remote and wearable medical sensing has the potential to create very large and high dimensional datasets. Medical time series databases must be able to efficiently store, index, and mine these datasets to enable medical professionals to effectively analyze data collected from their patients. Conventional high dimensional indexing methods are a two stage process. First, a superset of the true matches is efficiently extracted from the database. Second, supersets are pruned by comparing each of their objects to the query object and rejecting any objects falling outside a predetermined radius. This pruning stage heavily dominates the computational complexity of most conventional search algorithms. Therefore, indexing algorithms can be significantly improved by reducing the amount of pruning. This paper presents an online algorithm to aggregate biomedical times series data to significantly reduce the search space (index size) without compromising the quality of search results. This algorithm is built on the observation that biomedical time series signals are composed of cyclical and often similar patterns. This algorithm takes in a stream of segments and groups them to highly concentrated collections. Locality Sensitive Hashing (LSH) is used to reduce the overall complexity of the algorithm, allowing it to run online. The output of this aggregation is used to populate an index. The proposed algorithm yields logarithmic growth of the index (with respect to the total number of objects) while keeping sensitivity and specificity simultaneously above 98%. Both memory and runtime complexities of time series search are improved when using aggregated indexes. In addition, data mining tasks, such as clustering, exhibit runtimes that are orders of magnitudes faster when run on aggregated indexes.

    2010-03-01

    A clinical index that discriminates disease progression independent of histopathologic features may be valuable in the best timing of biopsy. This study addresses the question if a clinical index based on cortical echogenicity, renal length to body height ratio (KL/H), and serum creatinine levels predicts renal survival. The study enrolled 154 patients. Biopsy specimens were graded for chronic (glomerular obsolescence, segmental glomerular sclerosis, tubular atrophy and interstitial fibrosis) and acute (mesangial proliferation, leucocyte permeation, crescent and fibrinoid necrosis and interstital infiltrate) index by the sum of scored lesions. A chronic clinical index was created by the sum of scored cortical echogenicity relative to liver or spleen, creatinine serum levels and KL/H. The study end point was start on dialisis. Higher grade of chronic clinical and biopsy indices were associated with poorer long-term renal survival. Five out of six patients with serum creatinine levels > 2.5mg/dL, highest cortical echogenicity and KL/H < 0.60, before biopsy, started on dialysis and one increased creatinine levels up to 4.5 mg/dL. The chronic clinical index correlates well with chronic biopsy index. The chronic clinical index could be useful to predict a clinical setting in which a renal biopsy will show advanced chronic and irreversible lesion. In patients with highest grade of clinical parameters renal biopsy can be obviate. As a chronicity of illness index for groups of patients with renal medical diseases, the system could be useful in outcome comparisons and evaluation of therapeutic efficacy.

    Full Text Available The rapid advance of DNA sequencing technologies has yielded databases of thousands of genomes. To search and index these databases effectively, it is important that we take advantage of the similarity between those genomes. Several authors have recently suggested searching or indexing only one reference genome and the parts of the other genomes where they differ. In this paper we survey the twenty-year history of this idea and discuss its relation to kernelization in parameterized complexity.

    We study the problem of constructing an optical surface separating two homogeneous, isotropic media, one of which has a negative refractive index. In doing so, we develop a vector form of Snell's law, which is used to study surfaces possessing a certain uniform refraction property, both in the near and far field cases. In the near field problem, unlike the case when both materials have positive refractive index, we show that the resulting surfaces can be neither convex nor concave.

    Two of the most important properties of a porous silicon multilayer for photonic applications are flat interfaces and a relative large refractive index contrast between layers in the optical wavelength range. In this work, we studied the effect of the current density and HF electrolyte concentration on the refractive index of porous silicon. With the purpose of increasing the refractive index contrast in a multilayer, the refractive index of porous silicon produced at low current was studied in detail. The current density applied to produce the low porosity layers was limited in order to keep the electrolyte flow through the multilayer structure and to avoid deformation of layer interfaces. We found that an electrolyte composed of hydrofluoric acid, ethanol and glycerin in a ratio of 3:7:1 gives a refractive index contrast around 1.3/2.8 at 600 nm. Several multilayer structures with this refractive index contrast were fabricated, such as dielectric Bragg mirrors and microcavities. Reflectance spectra of the structures show the photonic quality of porous silicon multilayers produced under these electrochemical conditions. (copyright 2009 WILEY-VCH Verlag GmbH and Co.

    Similarity inference, one of the main bioinformatics tasks, has to face an exponential growth of the biological data. A classical approach used to cope with this data flow involves heuristics with large seed indexes. In order to speed up this technique, the index can be enhanced by storing additional information to limit the number of random memory accesses. However, this improvement leads to a larger index that may become a bottleneck. In the case of protein similarity search, we propose to decrease the index size by reducing the amino acid alphabet. The paper presents two main contributions. First, we show that an optimal neighborhood indexing combining an alphabet reduction and a longer neighborhood leads to a reduction of 35% of memory involved into the process, without sacrificing the quality of results nor the computational time. Second, our approach led us to develop a new kind of substitution score matrices and their associated e-value parameters. In contrast to usual matrices, these matrices are rectangular since they compare amino acid groups from different alphabets. We describe the method used for computing those matrices and we provide some typical examples that can be used in such comparisons. Supplementary data can be found on the website http://bioinfo.lifl.fr/reblosum. We propose a practical index size reduction of the neighborhood data, that does not negatively affect the performance of large-scale search in protein sequences. Such an index can be used in any study involving large protein data. Moreover, rectangular substitution score matrices and their associated statistical parameters can have applications in any study involving an alphabet reduction.

  6. WEATHER INDEX- THE BASIS OF WEATHER DERIVATIVES

    2011-07-01

    Full Text Available This paper approaches the subject of Weather Derivatives, more exactly their basic element the weather index. The weather index has two forms, the Heating Degree Day (HDD and the Cooling Degree Day (CDD. We will try to explain their origin, use and the relationship between the two forms of the index. In our research we started from the analysis of the weather derivatives and what they are based on. After finding out about weather index, we were interested in understanding exactly how they work and how they influence the value of the contract. On the national level the research in the field is scares, but foreign materials available. The study for this paper was based firstly on reading about Weather Derivative, and then going in the meteorogical field and determining the way by which the indices were determined. After this, we went to the field with interest in the indices, such as the energy and gas industries, and figured out how they determined the weather index. For the examples we obtained data from the weather index database, and calculated the value for the period. The study is made on a period of five years, in 8 cities of the European Union. The result of this research is that we can now understand better the importance of the way the indices work and how they influence the value of the Weather Derivatives. This research has an implication on the field of insurance, because of the fact that weather derivative are at the convergence point of the stock markets and the insurance market. The originality of the paper comes from the personal touch given to the theoretical aspect and through the analysis of the HDD and CDD index in order to show their general behaviour and relationship.

Besides maintaining an adequate supply of energy during exercise, this response may favor an increase in fat oxidation in the postprandial period before the exercise compared to high glycemic index (HGI) foods. The majority of the studies that evaluated the effect of foods differing in glycemic index on substrate oxidation during the postprandial period b...

    The objective of this work is to create a bilingual (French/English) Drug Information Portal (DIP), in a multi-terminological context and to emphasize its exploitation by an ATC automatic indexing allowing having more pertinent information about substances, organs or systems on which drugs act and their therapeutic and chemical characteristics. The development of the DIP was based on the CISMeF portal, which catalogues and indexes the most important and quality-controlled sources of institutional health information in French. DIP has created specific functionalities and uses specific drugs terminologies such as the ATC classification which used to automatic index the DIP resources. DIP is the result of collaboration between the CISMeF team and the VIDAL Company, specialized in drug information. DIP is conceived to facilitate the user information retrieval. The ATC automatic indexing provided relevant results in 76% of cases. Using multi-terminological context and in the framework of the drug field, indexing drugs with the appropriate codes or/and terms revealed to be very important to have the appropriate information storage and retrieval. The main challenge in the coming year is to increase the accuracy of the approach.

    Full Text Available OBJECTIVE: To present a Diet Quality Index proper for dietary intake studies of Brazilian adults. METHODS: A diet quality index to analyze the incorporation of healthy food choices was associated with a digital food guide. This index includes moderation components, destined to indicate foods that may represent a risk when in excess, and adequacy components that include sources of nutrients and bioactive compounds in order to help individuals meet their nutritional requirements. The diet quality index-digital food guide performance was measured by determining its psychometric properties, namely content and construct validity, as well as internal consistency. RESULTS: The moderation and adequacy components correlated weakly with dietary energy (-0.16 to 0.09. The strongest correlation (0.52 occurred between the component 'sugars and sweets' and the total score. The Cronbach's coefficient alpha for reliability was 0.36. CONCLUSION: Given that diet quality is a complex and multidimensional construct, the Diet Quality Index-Digital Food Guide, whose validity is comparable to those of other indices, is a useful resource for Brazilian dietary studies. However, new studies can provide additional information to improve its reliability.

    To obtain high quality in orthodontics; it is important to evaluate the treatment. There are many indices for evaluation of treatment outcome however all of them compare treatment outcome with ideal occlusion. Therefore Stockholm Eastman Index of Treatment Outcome (SEITO) was invented. This index relates the treatment outcome to the treatment goal. SEITO is a morphological index based on criteria from the records including study casts, and/or intra oral photos. The outcome of treatment is related to the treatment goal as stated in the records. Pre-treatment goals are divided into subgroups; overjet, vertical relation anterior/lateral), anterior cross bite, transverse relations, impacted teeth and space crowding/ spacing. Each subgroup is scored; the points are 0, 1, 3 or 5 depending on the severity of the malocclusion. The points for each subgroup are added to give a total sum of treatment goal points. Each post-treatment subgroup above is evaluated. If the treatment goal is fulfilled, the treatment outcome points are equal to the treatment goal points. If not - there is a reduction in the outcome points. Finally the outcome points are expressed as a percentage of the treatment goal points and form a measure of the success of treatment. SEITO index is a simple and quick way to obtain a picture of the quality of treatment outcome, and the only orthodontic index that relates the treatment outcome to the treatment goal.

  13. An absolute index (Ab-index to measure a researcher's useful contributions and productivity.

    Directory of Open Access Journals (Sweden)

    Akshaya Kumar Biswal

    Full Text Available Bibliographic analysis has been a very powerful tool in evaluating the effective contributions of a researcher and determining his/her future research potential. The lack of an absolute quantification of the author's scientific contributions by the existing measurement system hampers the decision-making process. In this paper, a new metric system, Absolute index (Ab-index, has been proposed that allows a more objective comparison of the contributions of a researcher. The Ab-index takes into account the impact of research findings while keeping in mind the physical and intellectual contributions of the author(s in accomplishing the task. The Ab-index and h-index were calculated for 10 highly cited geneticists and molecular biologist and 10 young researchers of biological sciences and compared for their relationship to the researchers input as a primary author. This is the first report of a measuring method clarifying the contributions of the first author, corresponding author, and other co-authors and the sharing of credit in a logical ratio. A java application has been developed for the easy calculation of the Ab-index. It can be used as a yardstick for comparing the credibility of different scientists competing for the same resources while the Productivity index (Pr-index, which is the rate of change in the Ab-index per year, can be used for comparing scientists of different age groups. The Ab-index has clear advantage over other popular metric systems in comparing scientific credibility of young scientists. The sum of the Ab-indices earned by individual researchers of an institute per year can be referred to as Pr-index of the institute.

  15. Automatic Indexing Based on Term Activity

    Science.gov (United States)

    Matsumura, Naohiro; Ohsawa, Yukio; Ishizuka, Mitsuru

    With the increasing number of electronic documents, automatic indexing from a document is an essential approach in information retrieval systems, such as search engines. This paper proposes an automatic indexing method named PAI (Priming Activation Indexing) which extracts keywords expressing assertions of a document. The basic idea is that since an author writes a document for insisting on his/her main point, impressive terms to be born in the mind of the reader could represent the asserted keywords of the document. Our approach employs a spreading activation model to extract keywords based on the activity of terms without using corpus, thesaurus, syntactic analysis, dependency relations between terms, and the other knowledge except for stop-word list. Experimental evaluations are reported by applying PAI to both papers and the archives of a mailing-list.

    The current proliferation of on-line information resources underscores the requirement for the ability to index collections of information and search and retrieve them in a convenient manner. This study develops criteria for analytically comparing the index and search engines and presents results for a number of freely available search engines. A product of this research is a toolkit capable of automatically indexing, searching, and extracting performance statistics from each of the focused search engines. This toolkit is highly configurable and has the ability to run these benchmark tests against other engines as well. Results demonstrate that the tested search engines can be grouped into two levels. Level one engines are efficient on small to medium sized data collections, but show weaknesses when used for collections 100MB or larger. Level two search engines are recommended for data collections up to and beyond 100MB.

    Health care services for registered "band" Indians in Ontario are provided primarily by the Canadian Federal Government. Complex management methods preclude the direct involvement of Indian people in the decisions for their health resource allocation. Health indicators, need, and health status indexes are reviewed. The biostatistics of mortality and demography of the Indian and reference populations are aggregated with hospitalization/morbidity experience as the Chen G'1 Index, as an indicator of normative and comparative need. This is weighted by linear measurements of perceived need for preventive medicine programs, as ranked and scaled values of priorities, Zj. These were determined by community survey on 11 Indian reserves using a non-probabilistic psychometric method of "pair comparisons," based upon "Thurstone's Law of Comparative Judgement.," The calculation of the aggregate single unit Indian Health Status Index [Log.G'1].Zj and its potential application in a "zero-base" budget is described.

    The Australian Natural Disaster Resilience Index Martin Thoms, Melissa Parsons, Phil Morley Bushfire and Natural Hazards Cooperative Research Centre, Geography and Planning, University of New England, Armidale NSW 2351, Australia. Natural hazard management policy directions in Australia - and indeed internationally - are increasingly being aligned to ideas of resilience. Resilience to natural hazards is the ability of individuals and communities to cope with disturbance and adversity and to maintain adaptive behaviour. Operationalizing the measurement and assessment of disaster resilience is often undertaken using a composite index, but this exercise is yet to be undertaken in Australia. The Australian Natural Disaster Resilience Index is a top-down, national scale assessment of the resilience of communities to natural hazards. Resilience is assessed based on two sets of capacities: coping and adaptive capacities. Coping capacity relates to the factors influencing the ability of a community to prepare for, absorb and recover from a natural hazard event. Adaptive capacity relates to the arrangements and processes that enable adjustment through learning, adaptation and transformation. Indicators are derived under themes of social character, economic capital, infrastructure and planning, emergency services, community capital, information and engagement and governance/leadership/policy, using existing data sets (e.g. census data) or evaluation of policy and procedure (e.g. disaster management planning). A composite index of disaster resilience is then computed for each spatial division, giving national scale coverage. The results of the Australian Natural Disaster Resilience Index will be reported in a State of Disaster Resilience report, due in 2018. The index is co-designed with emergency service agencies, and will support policy development, planning, community engagement and emergency management.

    Full Text Available Let $G$ be an $(n,m$-graph. We say that $G$ has property $(ast$ if for every pair of its adjacent vertices $x$ and $y$, there exists a vertex $z$, such that $z$ is not adjacent to either $x$ or $y$. If the graph $G$ has property $(ast$, then its complement $overline G$ is connected, has diameter 2, and its Wiener index is equal to $binom{n}{2}+m$, i.e., the Wiener index is insensitive of any other structural details of the graph $G$. We characterize numerous classes of graphs possessing property $(ast$, among which are trees, regular, and unicyclic graphs.

    2015-04-01

    A new type of photonic crystal (PC) named graded index (GRIN) PC was proposed by E. Centeno in 2005. It is obtained by appropriately modifying the parameters of a regular PC, thus resulting in gradual index variation. Many applications are inspired by this notion. This review will introduce different ways of designing GRIN PCs from both theoretical and experimental point of views. Some typical applications based on GRIN PCs are presented, followed by the focusing mechanism of GRIN PC. (copyright 2015 by WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

    2009-04-01

    Supernatural inflation is an attractive model based on just a flat direction with soft supersymmetry breaking mass terms in the framework of supersymmetry. The beauty of the model is that it needs no fine-tuning. However, the prediction of the spectral index is ns≳1, in contrast to experimental data. In this paper, we discuss supernatural inflation with the spectral index reduced to ns=0.96 without any fine-tuning, considering the general feature that a flat direction is lifted by a nonrenormalizable term with an A-term.

  12. Reflective random indexing for semi-automatic indexing of the biomedical literature.

    Vasuki, Vidya; Cohen, Trevor

    2010-10-01

    The rapid growth of biomedical literature is evident in the increasing size of the MEDLINE research database. Medical Subject Headings (MeSH), a controlled set of keywords, are used to index all the citations contained in the database to facilitate search and retrieval. This volume of citations calls for efficient tools to assist indexers at the US National Library of Medicine (NLM). Currently, the Medical Text Indexer (MTI) system provides assistance by recommending MeSH terms based on the title and abstract of an article using a combination of distributional and vocabulary-based methods. In this paper, we evaluate a novel approach toward indexer assistance by using nearest neighbor classification in combination with Reflective Random Indexing (RRI), a scalable alternative to the established methods of distributional semantics. On a test set provided by the NLM, our approach significantly outperforms the MTI system, suggesting that the RRI approach would make a useful addition to the current methodologies.

    The sesamoid index was originally described as an aid to the diagnosis of acromegaly. We performed this study to assess the value of the thumb sesamoid index in the diagnosis of psoriatic arthropathy. Retrospective measurement of the sesamoid index (length x width of the medial thumb sesamoid), along with the age and sex were recorded for patients as described below. Patients with psoriasis were subdivided into those with or without radiographic evidence of hand arthropathy. Fifty-nine consecutive patients attending rheumatology clinics with arthralgia and psoriasis were studied. Comparison groups with radiographic evidence of rheumatoid arthritis (52 patients), osteoarthritis (44) or normal hands (55) were also recorded. Twenty-one of 59 patients with psoriasis and arthropathy had a sesamoid index >40, compared with two of 52 with rheumatoid arthritis, none of 44 with osteoarthritis and none of 55 normals. Psoriatic arthropathy is a recognised cause of bone enlargement, usually in the phalanges due to periostitis and proliferative enthesopathy. We have confirmed that psoriatic hand arthropathy can cause significant enlargement of the thumb sesamoids, a feature which is easily quantified and may assist diagnosis. (orig.)

    2017-01-01

    This paper reports measurements of the refractive index of Homosil (Heraeus) over the wavelength range of 0.343.16 m and temperature range of 120335 K. These measurements were performed by using the Cryogenic High Accuracy Refraction Measuring System (CHARMS) facility at the NASAs Goddard Space Flight Center. These measurements were in support of an integrated Structural-Thermal-Optical-Performance (STOP) model that was developed for a field-widened Michelson interferometer that is being built and tested for the High Spectral Resolution Lidar (HSRL) project at the NASA Langley Research Center (LaRC). The cryogenic refractive index measurements were required in order to account for the highly sensitivity performance of the HSRL instrument to changes in refractive index with temperature, temperature gradients, thermal expansion, and deformation due to mounting stresses. A dense coverage of the absolute refractive index over the aforementioned wavelength and temperature ranges was used to determine the thermo-optic coefficient (dndT) and dispersion relation (dnd) as a function of wavelength and temperature. Our measurements of Homosil will be compared with measurements of other glasses from the fused silica family studied in CHARMS as well as measurements reported elsewhere in literature.

  13. Indexation and causation of financial markets

    CERN Document Server

    Tanokura, Yoko

    2015-01-01

    This book presents a new statistical method of constructing a price index of a financial asset where the price distributions are skewed and heavy-tailed and investigates the effectiveness of the method. In order to fully reflect the movements of prices or returns on a financial asset, the index should reflect their distributions. However, they are often heavy-tailed and possibly skewed, and identifying them directly is not easy. This book first develops an index construction method depending on the price distributions, by using nonstationary time series analysis. Firstly, the long-term trend of the distributions of the optimal Box–Cox transformed prices is estimated by fitting a trend model with time-varying observation noises. By applying state space modeling, the estimation is performed and missing observations are automatically interpolated. Finally, the index is defined by taking the inverse Box–Cox transformation of the optimal long-term trend. This book applies the method to various financial data. ...

    Gelin, Philippe; Wellekens, Christian J.

    1997-10-01

    We tackle the problem of multimedia indexing using keyword spotting on the spoken part of the data. Word spotting systems for indexing have to meet vary hard specifications: short response times to queries, speaker independent mode, open vocabulary in order to be able to track any keyword. To meet these constraints keyword models should be build according to their phonetic spelling and the process should be divided in two parts: preprocessing of the speech signal and query over a lattice of hypotheses. Different classification criteria have been studied for hypothesis generation: frame labeling, maximum likelihood and maximum a posteriori (MAP). The hypothesis probability is computed either through standard gaussian model or through a hybrid Hidden Markov Model-Neural Network. The training of the phonemic models is based either on Viterbi alignment or on recursive estimation and maximization of a posteriori probabilities. In the latter discriminant properties between phonemes are enforced. Tests have been conducted on TIMIT database as well as on TV news soundtracks. Interesting results have been obtained in time saving for the documentalist. The ultimate goal is to couple the soundtrack indexing with tools for video indexing in order to enhance the robustness of the system.

    Full Text Available Recent large trials with eicosapentaenoic acid (EPA and docosahexaenoic acid (DHA in the cardiovascular field did not demonstrate a beneficial effect in terms of reductions of clinical endpoints like total mortality, sudden cardiac arrest or other major adverse cardiac events. Pertinent guidelines do not uniformly recommend EPA + DHA for cardiac patients. In contrast, in epidemiologic findings, higher blood levels of EPA + DHA were consistently associated with a lower risk for the endpoints mentioned. Because of low biological and analytical variability, a standardized analytical procedure, a large database and for other reasons, blood levels of EPA + DHA are frequently assessed in erythrocytes, using the HS-Omega-3 Index® methodology. A low Omega-3 Index fulfills the current criteria for a novel cardiovascular risk factor. Neutral results of intervention trials can be explained by issues of bioavailability and trial design that surfaced after the trials were initiated. In the future, incorporating the Omega-3 Index into trial designs by recruiting participants with a low Omega-3 Index and treating them within a pre-specified target range (e.g., 8%–11%, will make more efficient trials possible and provide clearer answers to the questions asked than previously possible.

  10. Temporally resolved refractive index structure parameter measurement

    Science.gov (United States)

    Henriksson, Markus; Forsling, Robin

    2017-09-01

    The refractive index structure parameter is the most common measure of optical turbulence. It is defined as a statistical quantity for the Kolmogorov spectrum energy cascade of turbulent eddies of different sizes. As such it is formally assumed to be constant in time and space. However, the large scale variation with the diurnal cycle, with altitude or with terrain characteristics is well known. The ensemble average in the definition of the refractive index structure parameter is thus assumed to be applied over a restricted region in space and time. The question of how large volume is needed to determine the refractive index structure parameter and on how short temporal scales it can vary has not received significant attention. To study the temporal variation we have used two independent measurement systems to measure the path-averaged refractive index structure parameter over a 171 m path at 1 m above ground with higher than 1 Hz temporal resolution. One measurement system uses the differential angle-of-arrival of an array of LEDs. The other system measures the scintillation of a single path laser beam using a photon counting system, with time correlation of picosecond pulses for simultaneous measurement of signal and background and with temporal autocorrelation-based variance determination to separate turbulence related scintillations from shot noise. The data shows excellent agreement between the two measurement systems on second level temporal variation, giving confidence in that the measured values show true variation of the refractive index structure parameter. Large scale variation of up to two orders of magnitude can be coupled to solar insolation on this partly cloudy day. High frequency variations that are consistent between the systems used show factor two changes at time scales below one second.

    2016-01-01

    Several technical indicators have been proposed to assess the impact of authors and institutions. Here, we combine the h-index and the PageRank algorithm to do away with some of the individual limitations of these two indices. Most importantly, we aim to take into account value differences between citations-evaluating the citation sources by defining the h-index using the PageRank score rather than with citations. The resulting PR-index is then constructed by evaluating source popularity as well as the source publication authority. Extensive tests on available collections data (i.e., Microsoft Academic Search and benchmarks on the SIGKDD innovation award) show that the PR-index provides a more balanced impact measure than many existing indices. Due to its simplicity and similarity to the popular h-index, the PR-index may thus become a welcome addition to the technical indices already in use. Moreover, growth dynamics prior to the SIGKDD innovation award indicate that the PR-index might have notable predictive power.

  13. A new burn severity index based on land surface temperature and enhanced vegetation index

    2016-03-01

    Remotely sensed data have already become one of the major resources for estimating the burn severity of forest fires. Recently, Land Surface Temperature (LST) calculated from remote sensing data has been considered as a potential indicator for estimating burn severity. However, using the LST-based index alone may not be sufficient for estimating burn severity in the areas that has unburned trees and vegetation. In this paper, a new index is proposed by considering LST and enhanced vegetation index (EVI) together. The accuracy of the proposed index was evaluated by using 264 composite burn index (CBI) field sample data of the five fires across different regional eco-type areas in the Western United States. Results show that the proposed index performed equally well for post-fire areas covered with both sparse vegetation and dense vegetation and relatively better than some commonly-used burn severity indices. This index also has high potential of estimating burn severity if more accurate surface temperatures can be obtained in the future.

    1979-09-01

    You have heard about issues surrounding indexing and retrieval of nuclear records and automation and micrographics of these records. Now we are going to get each of you involved in indexing and assigning keywords. The first part of this hands-on workshop will be a very basic, elementary step-by-step introduction, concentrating on how to assign keywords. It is a workshop for beginners, People who have never done it before. It is planned to demonstrate what an analyst has to do to index and assign keywords to a document. Then I will take some pages of a report and demonstrate how I choose keywords for it. Then each of you will have a chance to do the same thing with similar pages from another report. Then we will discuss the variations ln the keywords you individually assigned. There are many systems that can be used. In this particular workshop we will cover only a system of building your own keyword listing as you index your documents. We will be discussing keywords or descriptors or subject words, but first I want to point out a few other critical points about indexing. When developing an indexing project the most important thing to do first lS decide what elements you want to retrieve by. Whether you go into a large computer retrieval system or a small three-by-five card system, you have to decide in advance what you want to retrieve. Then you can go on from there. If you only need to search by equipment number or by purchase order or by contract number, then you can use a very simple retrieval system. But if you want to be able to retrieve a record by any combination of elements, then you have to consistently input these into your system. For example, if you want to be able to ask for the drawings of the piping in the secondary cooling system, level 3, manufactured by a certain vendor, then you must have put the information into the index by a retrieval file point, in advance. I want to stress that the time spent in deciding what has to be retrievable is never

  19. Efficient protein structure search using indexing methods.

    Kim, Sungchul; Sael, Lee; Yu, Hwanjo

    2013-01-01

    Understanding functions of proteins is one of the most important challenges in many studies of biological processes. The function of a protein can be predicted by analyzing the functions of structurally similar proteins, thus finding structurally similar proteins accurately and efficiently from a large set of proteins is crucial. A protein structure can be represented as a vector by 3D-Zernike Descriptor (3DZD) which compactly represents the surface shape of the protein tertiary structure. This simplified representation accelerates the searching process. However, computing the similarity of two protein structures is still computationally expensive, thus it is hard to efficiently process many simultaneous requests of structurally similar protein search. This paper proposes indexing techniques which substantially reduce the search time to find structurally similar proteins. In particular, we first exploit two indexing techniques, i.e., iDistance and iKernel, on the 3DZDs. After that, we extend the techniques to further improve the search speed for protein structures. The extended indexing techniques build and utilize an reduced index constructed from the first few attributes of 3DZDs of protein structures. To retrieve top-k similar structures, top-10 × k similar structures are first found using the reduced index, and top-k structures are selected among them. We also modify the indexing techniques to support θ-based nearest neighbor search, which returns data points less than θ to the query point. The results show that both iDistance and iKernel significantly enhance the searching speed. In top-k nearest neighbor search, the searching time is reduced 69.6%, 77%, 77.4% and 87.9%, respectively using iDistance, iKernel, the extended iDistance, and the extended iKernel. In θ-based nearest neighbor serach, the searching time is reduced 80%, 81%, 95.6% and 95.6% using iDistance, iKernel, the extended iDistance, and the extended iKernel, respectively.

    Index tracking is an investment strategy in portfolio management which aims to construct an optimal portfolio to generate similar mean return with the stock market index mean return without purchasing all of the stocks that make up the index. The objective of this paper is to construct an optimal portfolio using the optimization model which adopts regression approach in tracking the benchmark stock market index return. In this study, the data consists of weekly price of stocks in Malaysia market index which is FTSE Bursa Malaysia Kuala Lumpur Composite Index from January 2010 until December 2013. The results of this study show that the optimal portfolio is able to track FBMKLCI Index at minimum tracking error of 1.0027% with 0.0290% excess mean return over the mean return of FBMKLCI Index. The significance of this study is to construct the optimal portfolio using optimization model which adopts regression approach in tracking the stock market index without purchasing all index components.

    Singh, Saransh; De Graef, Marc

    2017-02-01

    The dictionary-based approach to the indexing of diffraction patterns is applied to electron channeling patterns (ECPs). The main ingredients of the dictionary method are introduced, including the generalized forward projector (GFP), the relevant detector model, and a scheme to uniformly sample orientation space using the "cubochoric" representation. The GFP is used to compute an ECP "master" pattern. Derivative free optimization algorithms, including the Nelder-Mead simplex and the bound optimization by quadratic approximation are used to determine the correct detector parameters and to refine the orientation obtained from the dictionary approach. The indexing method is applied to poly-silicon and shows excellent agreement with the calibrated values. Finally, it is shown that the method results in a mean disorientation error of 1.0° with 0.5° SD for a range of detector parameters.

    Full Text Available Abstract The persistence of an epidemic of obesity and type 2 diabetes suggests that new nutritional strategies are needed if the epidemic is to be overcome. A promising nutritional approach suggested by this thematic review is metabolic effect of low glycaemic-index diet. The currently available scientific literature shows that low glycaemic-index diets acutely induce a number of favorable effects, such as a rapid weight loss, decrease of fasting glucose and insulin levels, reduction of circulating triglyceride levels and improvement of blood pressure. The long-term effect of the combination of these changes is at present not known. Based on associations between these metabolic parameters and risk of cardiovascular disease, further controlled studies on low-GI diet and metabolic disease are needed.

    Structural Equation Modeling (SEM) is a second generation statistical analysis techniques developed for analyzing the inter-relationships among multiple variables in a model simultaneously. There are two most common used methods in SEM namely Covariance-Based Structural Equation Modeling (CB-SEM) and Partial Least Square Path Modeling (PLS-PM). There have been continuous debates among researchers in the use of PLS-PM over CB-SEM. While there is few studies were conducted to test the performance of CB-SEM and PLS-PM bias in estimating simulation data. This study intends to patch this problem by a) developing the Comparative Bias Index and b) testing the performance of CB-SEM and PLS-PM using developed index. Based on balanced experimental design, two multivariate normal simulation data with of distinct specifications of size 50, 100, 200 and 500 are generated and analyzed using CB-SEM and PLS-PM.

    1980-06-01

    To adequately define the problem of waste management, quantitative measures of hazard must be used. This study reviews past work in the area of hazard indices and proposes a geotoxicity hazard index for use in characterizing the hazard of toxic material buried underground. Factors included in this index are: an intrinsic toxicity factor, formulated as the volume of water required for dilution to public drinking-water levels; a persistence factor to characterize the longevity of the material, ranging from unity for stable materials to smaller values for shorter-lived materials; an availability factor that relates the transport potential for the particular material to a reference value for its naturally occurring analog; and a correction factor to accommodate the buildup of decay progeny, resulting in increased toxicity.

  8. Effective spectral dispersion of refractive index modulation

    Vojtíšek, Petr; Květoň, Milan; Richter, Ivan

    2017-04-01

    For diffraction effects inside photopolymer materials, which act as volume diffraction systems (e.g. gratings), refractive index modulation is one of the key parameters. Due to its importance it is necessary to study this parameter from many perspectives, one of which is its value for different spectral components, i.e. its spectral dispersion. In this paper, we discuss this property and present an approach to experimental and numerical extraction and analysis (via rigorous coupled wave analysis and Cauchy’s empirical relation) of the effective dispersion of refractive index modulation based on an analysis of transmittance maps measured in an angular-spectral plane. It is indicated that the inclusion of dispersion leads to a significantly better description of the real grating behavior (which is often necessary in various design implementations of diffraction gratings) and that this estimation can be carried out for all the diffraction orders present.

    This report describes the NASA Lexical Dictionary, a machine aided indexing system used online at the National Aeronautics and Space Administration's Center for Aerospace Information (CASI). This system is comprised of a text processor that is based on the computational, non-syntactic analysis of input text, and an extensive 'knowledge base' that serves to recognize and translate text-extracted concepts. The structure and function of the various NLD system components are described in detail. Methods used for the development of the knowledge base are discussed. Particular attention is given to a statistically-based text analysis program that provides the knowledge base developer with a list of concept-specific phrases extracted from large textual corpora. Production and quality benefits resulting from the integration of machine aided indexing at CASI are discussed along with a number of secondary applications of NLD-derived systems including on-line spell checking and machine aided lexicography.

    1980-10-01

    In an effort to determine the environmental intensities to which energy materials in transit may be exposed, a Data Center of technical environmental information has been established by Sandia National Laboratories, Division 5523, for the DOE Office of Transportation Fuel Storage. This document is an index which can be used to request data of interest. Access to the information held is not limited to Sandia personnel. The purpose of the Transportation Technical Environmental Information Center is to collect, analyze, store, and make available descriptions of the environment of transportation expressed in engineering terms. The data stored in the Center are expected to be useful in a variety of transportation related analyses. Formulations of environmental criteria for shipment of cargo, risk assessments, and detailed structural analyses of shipping containers are examples where these data have been applied. For purposes of indexing and data retrieval, the data are catalogued under two major headings: Normal and Abnormal Environments.

Knowing a document’s topics helps people judge its relevance quickly. However, assigning topics manually is labor intensive. This thesis shows how to generate them automatically in a way that competes with human performance. Three kinds of indexing are investigated: term assignment, a task commonly performed by librarians, who select topics from a controlled vocabulary; tagging, a popular activity of web users, who choose topics freely; and a new method of keyphrase extraction, where topics are equated to Wikipedia article names. A general two-stage algorithm is introduced that first selects candidate topics and then ranks them by significance based on their properties. These properties draw on statistical, semantic, domain-specific and encyclopedic knowledge. They are combined using a machine learn...

    Full Text Available The research presents photography indexing methods from the perspective of Henri Cartier Bresson's work and the decisive instant. The methodology is exploratory and descriptive, with a qualitative approach, using documental research procedures, survey and content analysis. The research was based on the method of classification and indexing by studying the best indexing method for the photographs of Henri Cartier-Bresson, in order to extract as much information as possible from the visual representation of the document (photographs, and to minimize the losses in this transcription. For this, we used the four methods of indexing of photographs developed by the authors Panofsky (1986, Smit (1986, Manini (2002 and Rodrigues (2007, applying them to three (03 Bresson photographs. After the application, we performed a comparative analysis and discussion of the results.

It leads to violations of carbohydrate and lipidic exchange, development of obesity, diabetes, cardiovascular and other diseases. Relevance of development of foodstuff, in particular – the confectionery promoting decrease in risk of developing of such pathologies is proved. A research objective – development of a compounding of wafers with the lowered glycemic index. As an object of a research the wafers baked in house conditions are chosen. In work various characteristics are analysed (hygroscopicity, a cariogenicity sweet degree, power value, a glicemic index and a glycemic response the sweetening substances, the choice of fructose as sugar substitute for production of wafers with the lowered glycemic index is reasonable. By optimization of a compounding of wafers the amount of sugar was replaced with amount of sweetener, equivalent on sweet. As a result of predesigns the interval of a variation of amount of the fructose entered into a compounding of wafers is established. Further assessment of the indicators of quality forming consumer demand of products – appearance, taste, a smell, existence of a crunch is carried out. Humidity of the received wafers after their production and in the course of storage is also investigated. Decrease in a glycemic index was fixed by amount of glucose in blood. Its measurements saw by means of the glucose meter "on an empty stomach" and after the use of wafers to a complete recovery of level of sugar in blood. The confectionery made on the optimized compounding practically doesn't differ on caloric content from a control sample, and glucose level in blood after their use on about 20% below.

    We present a phase-coherent timing solution for PSR J1640–4631, a young 206 ms pulsar using X-ray timing observations taken with NuSTAR. Over this timing campaign, we have measured the braking index of PSR J1640–4631 to be n = 3.15 ± 0.03. Using a series of simulations, we argue that this unusually high braking index is not due to timing noise, but is intrinsic to the pulsar's spin-down. We cannot, however, rule out contamination due to an unseen glitch recovery, although the recovery timescale would have to be longer than most yet observed. If this braking index is eventually proven to be stable, it demonstrates that pulsar braking indices greater than three are allowed in nature; hence, other physical mechanisms such as mass or magnetic quadrupoles are important in pulsar spin-down. We also present a 3σ upper limit on the pulsed flux at 1.4 GHz of 0.018 mJy.

  3. Indexing molecules with chemical graph identifiers.

    Gregori-Puigjané, Elisabet; Garriga-Sust, Rut; Mestres, Jordi

    2011-09-01

    Fast and robust algorithms for indexing molecules have been historically considered strategic tools for the management and storage of large chemical libraries. This work introduces a modified and further extended version of the molecular equivalence number naming adaptation of the Morgan algorithm (J Chem Inf Comput Sci 2001, 41, 181-185) for the generation of a chemical graph identifier (CGI). This new version corrects for the collisions recognized in the original adaptation and includes the ability to deal with graph canonicalization, ensembles (salts), and isomerism (tautomerism, regioisomerism, optical isomerism, and geometrical isomerism) in a flexible manner. Validation of the current CGI implementation was performed on the open NCI database and the drug-like subset of the ZINC database containing 260,071 and 5,348,089 structures, respectively. The results were compared with those obtained with some of the most widely used indexing codes, such as the CACTVS hash code and the new InChIKey. The analyses emphasize the fact that compound management activities, like duplicate analysis of chemical libraries, are sensitive to the exact definition of compound uniqueness and thus still depend, to a minor extent, on the type and flexibility of the molecular index being used.

    To study heart disease in childhood aiming to know its incidence and consequences upon the nutritional status. Two-hundred patients were distributed in three groups: 1) 113 (56.5%) with congenital acyanotic form; 2) 19 (9.5%) with congenital cyanotic form and 3) 68 (34%) with acquired forms. All of them regularly visiting the ambulatory service of Paediatric cardiology of the Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da USP from 1987 until 1990. The majority (92%) of the children (being 56% male and aging 5.1 +/- 0.4 years-old) showed nutritional indexes between 5 and 95 (percentile scale). The overall diagnosis distribution were: 1) ventricular septal defect (51 cases); 2) atrial septal defect (21 cases); 3) valvular diseases (21 cases); 4) arrhythmias (20 cases); 5) cardiac involvement of systemic diseases (20 cases); and 6) tetralogy complex (8 cases). Twelve patients (6%) were underscored (below percentile 5) and only 4 (2%) scored above percentile 95 (obese patients). The comparison of the mean indexes were found statistical different (p less than 0.05), being the cyanotic congenital forms the worst ones and the acquired forms the best one. Heart disease in childhood is associated to nutritional index deficits in the majority of the cases.

  5. Efficient Joins with Compressed Bitmap Indexes

    Energy Technology Data Exchange (ETDEWEB)

    Computational Research Division; Madduri, Kamesh; Wu, Kesheng

    2009-08-19

    We present a new class of adaptive algorithms that use compressed bitmap indexes to speed up evaluation of the range join query in relational databases. We determine the best strategy to process a join query based on a fast sub-linear time computation of the join selectivity (the ratio of the number of tuples in the result to the total number of possible tuples). In addition, we use compressed bitmaps to represent the join output compactly: the space requirement for storing the tuples representing the join of two relations is asymptotically bounded by min(h; n . cb), where h is the number of tuple pairs in the result relation, n is the number of tuples in the smaller of the two relations, and cb is the cardinality of the larger column being joined. We present a theoretical analysis of our algorithms, as well as experimental results on large-scale synthetic and real data sets. Our implementations are efficient, and consistently outperform well-known approaches for a range of join selectivity factors. For instance, our count-only algorithm is up to three orders of magnitude faster than the sort-merge approach, and our best bitmap index-based algorithm is 1.2x-80x faster than the sort-merge algorithm, for various query instances. We achieve these speedups by exploiting several inherent performance advantages of compressed bitmap indexes for join processing: an implicit partitioning of the attributes, space-efficiency, and tolerance of high-cardinality relations.

  6. Analysis of Sugarcane Juice Quality Indexes

    2017-01-01

    Full Text Available The analysis of the quality indexes of sugarcane juice plays a vital role in the process of refining sugarcane, breeding, cultivation, and production management. The paper analyzes the dynamic laws of five quality indexes (i.e., brix, purity, polarization, sucrose content, and reducing sugar combined with graphs over time along the course of crushing season (December–March in Guangxi province of China. During this time, the sugarcane is in the mature stage and hypermature stage. At the beginning of December to early January, during which sugarcane is in the later stage of maturity, the nutrients are accumulating, causing brix, purity, polarization, and sucrose content increase. At the beginning of January to mid-February, due to low temperature and insufficient light, it is not conducive to accumulation of nutrients. However, there is the so-called “sugar back” phenomenon and reducing sugar rises gradually in March, leading to deterioration of the quality of sugarcane juice. The results show that timely harvest of sugarcane is beneficial for sugar making. The regression analysis results show that some of quality indexes have strong correlation between them and the regression models are extremely significant, indicating that the prediction results are ideal.

    The evidence for a role of diet on ovarian cancer prevention remains inconclusive. While many studies have evaluated individual foods and food groups, the evaluation of a comprehensive dietary quality index for predicting cancer risk has received little attention. This study investigates the association between the Healthy Eating Index (HEI), which reflects adherence to the current USDA Dietary Guidelines for Americans, and ovarian cancer risk in a population-based case-control study in New Jersey. A total of 205 cases and 390 controls completed the Block 98.2 Food Frequency Questionnaire (FFQ) in addition to reporting on potential risk factors for ovarian cancer. FFQ data were then utilized to calculate the HEI score, and cup, ounce, gram, or caloric equivalents for the 12 different food groups comprising the index. In multivariate models the OR for the highest tertile of the HEI score compared to the lowest (reflecting a better diet compared to a worse diet) was 0.90 (95% CI: 0.55–1.47). There was limited evidence for a statistically significant association between any of the 12 individual food components and ovarian cancer risk. Based on this study’s results, neither individual food groups nor dietary quality showed potential for preventing ovarian cancer. PMID:21286802

Engle-Granger and Johansen tests were used to detect whether and to what extent the series co-move in the long run and which one of the variables contributes proactively to such an equilibrium by reacting to disequilibria from the long-run path. The estimates highlight that i the two wine indexes have a higher Sharpe ratio compared to the general stock market index, revealing wine stocks as a profitable investment per se, and ii the absence of cointegration among the three series and the existence of possible diversification benefits. In fact, in the long-run price do not move together and, therefore, investors may be better off by including wine stocks into investment portfolios and take advantage of diversification

    The aim of the present investigation was to determine the possibilities of the Reid's colposcopic index to diffentiate the grade of the findings in sexually active teenagers. The study was based on 83 girls without child-birth in history, aged between 14 an 19 (mean age 18.13 years)q with different grade cytological and/or colposcopic atypia. Colposcopic findings were joined, according to semiobjective Reid's index and the results achieved were compared with the histological findings from the target biopsies. The results from the colposcopic investigation were divided into 4 groups: in group 0--without pathological findings were classified 12 cases, in gr. 1 (Reid)--42, in gr. 2 (Reid)--24 and in gr. 3 (Reid)--5 patients. Histological equivalents were summarized as follow: normal and papiloma epithelium--in 27, CIN I--in 36, CIN II--15q and CIN III--5 cases. The investigation performed, shows the good correlation (91.6%) between colposcopic impression and histological diagnosis, and this put the question about the place and role of the Reid's colposcopic index in predicting the severity of the pathological changes of the uterine cervix in sexually active adolescent girls.

    To evaluate the perinatal outcome with the abnormal umbilical cord coiling index. This prospective study was carried out in the department of OBG at Adichunchangiri Institute of Medical Sciences, B.G.Nagara, Mandya, Karnataka, India from January 2008 to August 2010. 200 patients who were in active labour with term gestations, irrespective of their parities, who had singleton pregnancies with live babies who were either delivered by vaginal or LSCS were included in the study. Umbilical cord coiling index was calculated and it was correlated with various perinatal parameters like birth weight, meconium stained liquor, Apgar score, ponderal index and foetal growth restriction. Chi square and Fisher exact tests were used to find the significance of study parameters. There was a significant correlation between the hypercoiled cords (UCI >90(th) percentile) and IUGR of the babies (p value of UCI which was UCI which was > 90(th) percentile was associated with IUGR and low ponderal indices. Hypocoiled cords or UCI which was <10th percentile was associated with meconium staining, Apgar score at 1 min of <4 and at 5 min of <7, more LSCS rates and more NICU admissions.

  11. A new index quantifying the precipitation extremes

    Events of extreme precipitation have a great impact on society. They are associated with flooding, erosion and landslides.Various indices have been proposed to quantify these extreme events and they are mainly related to daily precipitation amount, which are usually available for long periods in many places over the world. The climate signal related to changes in the characteristics of precipitation extremes is different over various regions and it is dependent on the season and the index used to quantify the precipitation extremes. The climate model simulations and empirical evidence suggest that warmer climates, due to increased water vapour, lead to more intense precipitation events, even when the total annual precipitation is slightly reduced. It was suggested that there is a shift in the nature of precipitation events towards more intense and less frequent rains and increases in heavy rains are expected to occur in most places, even when the mean precipitation is not increasing. This conclusion was also proved for the Romanian territory in a recent study, showing a significant increasing trend of the rain shower frequency in the warm season over the entire country, despite no significant changes in the seasonal amount and the daily extremes. The shower events counted in that paper refer to all convective rains, including torrential ones giving high rainfall amount in very short time. The problem is to find an appropriate index to quantify such events in terms of their highest intensity in order to extract the maximum climate signal. In the present paper, a new index is proposed to quantify the maximum precipitation intensity in an extreme precipitation event, which could be directly related to the torrential rain intensity. This index is tested at nine Romanian stations (representing various physical-geographical conditions) and it is based on the continuous rainfall records derived from the graphical registrations (pluviograms) available at National

  12. Two-dimensional refractive index and birefringence profiles of a graded index bent optical fibre

    A theory to recover refractive index profile of the bent graded index (GRIN) optical fibre, in core region, is proposed. This theory is applied to the bent GRIN optical fibre when it is located orthogonal in the light path of the object arm in digital holographic phase shifting interferometer; like Mach-Zehnder interferometer. In the experiment, the fibre is bent with two different bending radii and fixed on a microscope slide keeping it immersed in matching liquid. The produced phase shifted holograms, with the presence of the fibre, are recorded using an attached CCD camera. Two different processes controlling the index profile shape of the bent GRIN optical fibre are assumed. In the first process, a linear index variation is evolved from stresses in the direction of the bent radius. In the second one, there is a release of these stresses near the fibre surface, which depends on the fibre's radius. This will affect the outer free surface of the cladding. Based on these assumptions, we are able to construct the index profile in two dimensions normal to the optical axis. We propose two functions to describe the refractive index profiles in cladding and the core regions of the bent GRIN optical fibre. The recorded phase shifted holograms are combined, reconstructed and analyzed to get the phase map of the bent GRIN optical fibre. Comparing the extracted optical phase differences with the calculated ones, a good agreement between them is found. This means that the used two dimensional proposed functions, which are describing cladding and the core indices profiles, are the most proper in this situation. Thus, we are able to determine a realistic induced birefringence profile inside the fibre which is generated by a bending operation, not only in the cladding but also in graded index core region as well.

    The H-index is widely used to quantify and standardize researchers' scientific impact. However, the H-index does not account for the fact that co-authors rarely contribute equally to a paper. Accordingly, we propose the use of a stratified H-index to measure scientific impact. The stratified H......-index supplements the conventional H-index with three separate H-indices: one for first authorships, one for second authorships and one for last authorships. The stratified H-index takes scientific output, quality and individual author contribution into account....

    Full Text Available Lack of reliable data on the optical properties of black and green liquors complicates control of their composition in technological process of sulphate cellulose production. In this regard the paper presents measurement results of refraction index of black liquors n (k,t at concentration in solutions of bone-dry solids up to k = 70% and at temperatures t = 10-90 °C, as well as in green liquors n(C,t at the total alkalinity of C = 0-250 g/l and in the same temperature range. All samples of solutions of black and green liquors were provided by Segezha Pulp and Paper Mill and certified in factory laboratory. Measurements were taken by means of the laboratory Abbe refractometer (URL-1, digital refractometer "Expert pro", goniometer spectrometer GS-5, and ultra-violet spectrophotometer as well. The work also presents optical D density spectra in the ultra-violet region of the wavelengths for the samples of a green liquor and main mineral component to form it, i.e. Na2S (sodium sulphide. To calculate dispersion of n (λ in the visible spectral range, here a Lorentz single-oscillator model was used. The paper discusses study results of dispersive dependence of refraction index in green liquors with various concentration and chemical components of n (λ, C forming them at t = 20°C. Computing and experimental dependences of n (λ had not only good qualitative, but also quite satisfactory quantitative compliance. The work also describes main mineral components defining optical properties in these liquors. Given here data on concentration and temperature dependences of a refraction index in black n(k,t and green n(C,t liquors have been never published before. These data are of essential interest to control soda recovery technologies in manufacturing sulphate cellulose. The received results can be also used to tune and calibrate modern domestic and foreign industrial refractometers.

    The work is conducted in the framework of the European programme SIDDACLICH (SImulation, Diagnosis and Direction of the Anthropogenic CLImate CHange), co-ordinated by DKRZ (Deutsches Klimarechenzentrum) of Hamburg. This project aims to perform and analyze climatic simulations with coupled models in order to study detection and impact of possible climate change linked to human activities. EDF/R and D D contribution to this project is limited to the delivery of diagnosis programs concerning acetylacetone blocking detection, in order to permit the evaluation of the impact of climate change on this type of situation from the results of coupled simulations performed in the project. First, two blocking indexes had been coded from works of Mullen and Kaas and Branstator, reported in the literature and applied to evaluate the impact of the augmentation of CO{sub 2} gas atmospheric concentration on a situation of this type, staring from the results of different equilibrium simulation results of atmospheric only simulations performed in the framework of a previous programme on Anthropogenic Climate Change. Then, these indexes have been confronted with a more commonly used index, the Tibaldi et al. index, using a long series of data covering the period 1963-1988, in order to have an idea of the situations detected by each index for the Euro-Atlantic sector in winters for which the situation is well known.

    1997-11-01

    The authors develop new SVD-updating algorithms for three types of updating problems arising from Latent Semantic Indexing (LSI) for information retrieval to deal with rapidly changing text document collections. They also provide theoretical justification for using a reduced-dimension representation of the original document collection in the updating process. Numerical experiments using several standard text document collections show that the new algorithms give higher (interpolated) average precisions than the existing algorithms and the retrieval accuracy is comparable to that obtained using the complete document collection.

    One reviews the recently introduced field of matter-wave "meta-optics", i.e. the extension of optical negative-index media (NIM) to atom optics. After emphasizing the differences with light meta-optics and particularly the necessary transient character of NIM's in atom optics, we present the way of generating matter-wave NIM's and their general properties: negative refraction, atom meta-lenses. Finally their specific features are reviewed: longitudinal wave packet narrowing associated to a time-reversal effect, transient revivals of evanescent matter waves and atom reflection echoes at a potential barrier.

    Many methods are used to track patient exposure during acquisition of plain film radiographs. A uniform international standard would aid this process. To evaluate and describe a new, simple quality-assurance method for monitoring patient exposure. This method uses the ''exposure index'' and the ''deviation index,'' recently developed by the International Electrotechnical Commission (IEC) and American Association of Physicists in Medicine (AAPM). The deviation index measures variation from an ideal target exposure index value. Our objective was to determine whether the exposure index and the deviation index can be used to monitor and control exposure drift over time. Our Agfa workstation automatically keeps a record of the exposure index for every patient. The exposure index and deviation index were calculated on 1,884 consecutive neonatal chest images. Exposure of a neonatal chest phantom was performed as a control. Acquisition of the exposure index and calculation of the deviation index was easily achieved. The weekly mean exposure index of the phantom and the patients was stable and showed <10% change during the study, indicating no exposure drift during the study period. The exposure index is an excellent tool to monitor the consistency of patient exposures. It does not indicate the exposure value used, but is an index to track compliance with a pre-determined target exposure. (orig.)

    The purpose of this study was to translate the Insomnia Severity Index (ISI) into Arabic (Fusha dialect), and obtain preliminary reliability and validity estimates for the translated version. Arabic populations experience sleep problems that interfere with their vitality and quality of life. The ISI was established to screen for insomnia in both clinical and research situations. This study used a descriptive correlational design. The ISI was translated into Arabic using the back-translation method and compared with three other sleep measures: the Pittsburgh Sleep Quality Index, the Epworth Sleepiness Scale, and the Vitality Subscale from the Medical Outcomes Study Short Form-36. These measures were administered to 35 healthy Arabic bilingual participants from three community locations. The mean ISI score was 9.2 (SD = 5.8; range 0-20). Internal consistency reliability was 0.84. The correlations between the total ISI score and the single items ranged from 0.49 to 0.92 (p Arabic populations in their own countries. Preliminary psychometric estimates show that the translated ISI is reliable and valid in this community-dwelling Arabic sample. The translated ISI allows for Arabic researchers to screen for insomnia and plan for future intervention studies. © 2011 Sigma Theta Tau International.

    Since 2008, BNF Technology Inc. and Kyung Hee University have developed the 'Plant Health Index (PHI)' which is a software package to detect 'unhealthy conditions' of plant equipment in advance. While the difference between a setpoint and an operational condition is called 'process margin', the residual between an anticipated normal condition and an operational condition is called 'process uncertainty' or 'healthiness' in this study. It is obvious that the anomalies in process uncertainty can be observed earlier than those in process margin, which is the concept of 'early-warning' proposed in the recent condition-based maintenance (CBM) studies. One of the key factors for implementing the early warning capability should be how to expect the anticipated normal conditions using available information. The PHI was developed on the basis of empirical models, and we have published a few papers with regarding to the core technologies of the PHI. However, the overall architecture and features of the PHI have not been introduced to academic area so far. This paper delineates the overview of the PHI, and focuses on the recently developed module, which is the health index generator

    The Ranking Index of Components (RIC) is an Asset Reliability Manager (ARM), which itself is a Web Enabled front end where plant database information fields from several disparate databases are combined. That information is used to create a specific weighted number (Ranking Index) relating to that components health and risk to the site. The higher the number, the higher priority that any work associated with that component receives. ARM provides site Engineering, Maintenance and Work Control personnel with a composite real time - (current condition) look at the components 'risk of not working' to the plant. Information is extracted from the existing Computerized Maintenance management System (CMMS) and specific site applications and processed nightly. ARM helps to ensure that the most important work is placed into the workweeks and the non value added work is either deferred, frequency changed or deleted. This information is on the web, updated each night, and available for all employees to use. This effort assists the work management specialist when allocating limited resources to the most important work. The use of this tool has maximized resource usage, performing the most critical work with available resources. The ARM numbers are valued inputs into work scoping for the workweek managers. System and Component Engineers are using ARM to identify the components that are at 'risk of failure' and therefore should be placed into the appropriate work week schedule.

    2007-01-01

    Machine Aided Indexing (MAI) is a Web-based application program for aiding the indexing of literature in the NASA Scientific and Technical Information (STI) Database. MAI was designed to be a convenient, fully interactive tool for determining the subject matter of documents and identifying keywords. The heart of MAI is a natural-language processor that accepts, as input, any user-supplied text, including abstracts, full documents, and Web pages. Within seconds, the text is analyzed and a ranked list of terms is generated. The 17,800 terms of the NASA Thesaurus serve as the foundation of the knowledge base used by MAI. The NASA Thesaurus defines a standard vocabulary, the use of which enables MAI to assist in ensuring that STI documents are uniformly and consistently accessible. Of particular interest to traditional users of the NASA Thesaurus, MAI incorporates a fully searchable thesaurus display module that affords word-search and hierarchy- navigation capabilities that make it much easier and less time-consuming to look up terms and browse, relative to lookup and browsing in older print and Portable Document Format (PDF) digital versions of the Thesaurus. In addition, because MAI is centrally hosted, the Thesaurus data are always current.

    2017-07-01

    The limitation of the fixed time scale in the Palmer drought severity index (PDSI) family has long been criticized in drought literatures. By modifying the algorithm of duration factors estimation of the self-calibrating PDSI (SC-PDSI), this paper proposed a new approach that could extend the time scale in a wide range. The properties of these newly derived SC-PDSI variants (denoted as SC-PDSIx) at short, medium, and long time scales, respectively, were evaluated through comparisons with the multiscalar standardized precipitation evapotranspiration index (SPEI) over 134 meteorological sites in China. Results show that new SC-PDSIx generally inherits the advantages of original SC-PDSI with a rather stable behavior in aspects of drought frequency and other statistical characteristics. Besides, the spatiotemporal pattern of the 2011 drought reflected by matched SC-PDSIx and SPEI is very similar, indicating that the multiscalar SC-PDSI could be a useful alternative to monitor droughts at different time scales.

    We propose and analyze a novel Multi-Index Monte Carlo (MIMC) method for weak approximation of stochastic models that are described in terms of differential equations either driven by random measures or with random coefficients. The MIMC method is both a stochastic version of the combination technique introduced by Zenger, Griebel and collaborators and an extension of the Multilevel Monte Carlo (MLMC) method first described by Heinrich and Giles. Inspired by Giles s seminal work, instead of using first-order differences as in MLMC, we use in MIMC high-order mixed differences to reduce the variance of the hierarchical differences dramatically. Under standard assumptions on the convergence rates of the weak error, variance and work per sample, the optimal index set turns out to be of Total Degree (TD) type. When using such sets, MIMC yields new and improved complexity results, which are natural generalizations of Giles s MLMC analysis, and which increase the domain of problem parameters for which we achieve the optimal convergence, O(TOL-2).

    We propose and analyze a novel Multi-Index Monte Carlo (MIMC) method for weak approximation of stochastic models that are described in terms of differential equations either driven by random measures or with random coefficients. The MIMC method is both a stochastic version of the combination technique introduced by Zenger, Griebel and collaborators and an extension of the Multilevel Monte Carlo (MLMC) method first described by Heinrich and Giles. Inspired by Giles’s seminal work, instead of using first-order differences as in MLMC, we use in MIMC high-order mixed differences to reduce the variance of the hierarchical differences dramatically. Under standard assumptions on the convergence rates of the weak error, variance and work per sample, the optimal index set turns out to be of Total Degree (TD) type. When using such sets, MIMC yields new and improved complexity results, which are natural generalizations of Giles’s MLMC analysis, and which increase the domain of problem parameters for which we achieve the optimal convergence.

    Background: Multiple diet indexes have been developed to capture the Dietary Approaches to Stop Hypertension (DASH) dietary pattern and examine relations with health outcomes but have not been compared within the same study population to our knowledge. Objective: We compared 4 established DASH indexes and examined associations with colorectal cancer. Design: Scores were generated from a food-frequency questionnaire in the NIH-AARP Diet and Health Study (n = 491,841). Separate indexes defined by Dixon (7 food groups, saturated fat, and alcohol), Mellen (9 nutrients), Fung (7 food groups and sodium), and Günther (8 food groups) were used. HRs and 95% CIs for colorectal cancer were generated by using Cox proportional hazard models. Results: From 1995 through 2006, 6752 incident colorectal cancer cases were ascertained. In men, higher scores were associated with reduced colorectal cancer incidence by comparing highest to lowest quintiles for all indexes as follows: Dixon (HR: 0.77; 95% CI: 0.69, 0.87), Mellen (HR: 0.78; 95% CI: 0.71, 0.86), Fung (HR: 0.75; 95% CI: 0.68, 0.83), and Günther (HR: 0.81; 95% CI: 0.74, 0.90). Higher scores in women were inversely associated with colorectal cancer incidence by using methods defined by Mellen (HR: 0.79; 95% CI: 0.68, 0.91), Fung (HR: 0.84; 95% CI: 0.73, 0.96), and Günther (HR: 0.84; 95% CI: 0.73.0.97) but not Dixon (HR: 1.01; 95% CI: 0.80, 1.28). Conclusion: The consistency in findings, particularly in men, suggests that all indexes capture an underlying construct inherent in the DASH dietary pattern, although the specific index used can affect results.

    Price changes of goods and services used in biomedical research and development have important effects on the costs of conducting research. We summarize the trends suggested by a recently constructed biomedical research and development price index, which measures the effects of price changes on the inputs to biomedical research from 1979 to 1986. The fixed-weighted index uses fiscal year 1984 National Institutes of Health expenditure patterns in developing the weights. The rate of increase shown in the price index peaked in 1981 and slowed in following years. However, in most years, the rate of increase in the price index has exceeded the rate of increase in other major price indexes, such as the consumer price index, the producer price index, and the Gross National Product fixed-weighted price index.

  1. Provenance graph query method based on double layer index structure

    Order to solve the problem that the efficiency of the existing source map is low and the resource occupancy rate is high, considering the relationship between the origin information and the data itself and the internal structure of the origin information, a method of provenance graph query based on double layer index structure is proposed. Firstly, we propose a two layer index structure based on the global index of the dictionary table and the local index based on the bitmap. The global index is used to query the server nodes stored in the source map. The local index is used to query the global index. Finally, based on the double-level index structure, a method of starting map query is designed. The experimental results show that the proposed method not only improves the efficiency of query and reduces the waste of memory resources.

    indexing and achieves workload-awareness by controlling the underlying index’s filtering quality. QU-Trade safely drops index updates, increasing the overlap in the index when the workload is update-intensive, and it restores the filtering capabilities of the index when the workload becomes query-intensive......The increased deployment of sensors and data communication networks yields data management workloads with update loads that are intense, skewed, and highly bursty. Query loads resulting from location-based services are expected to exhibit similar characteristics. In such environments, index...... structures can easily become performance bottlenecks. We address the need for indexing that is adaptive to the workload characteristics, called workload-aware, in order to cover the space in between maintaining an accurate index, and having no index at all. Our proposal, QU-Trade, extends R-tree type...

  10. The Extreme Climate Index: a novel and multi-hazard index for extreme weather events.

    In this presentation we introduce the Extreme Climate Index (ECI): an objective, multi-hazard index capable of tracking changes in the frequency or magnitude of extreme weather events in African countries, thus indicating that a shift to a new climate regime is underway in a particular area. This index has been developed in the context of XCF (eXtreme Climate Facilities) project lead by ARC (African Risk Capacity, specialised agency of the African Union), and will be used in the payouts triggering mechanism of an insurance programme against risks related to the increase of frequency and magnitude of extreme weather events due to climate regimes' changes. The main hazards covered by ECI will be extreme dry, wet and heat events, with the possibility of adding region-specific risk events such as tropical cyclones for the most vulnerable areas. It will be based on data coming from consistent, sufficiently long, high quality historical records and will be standardized across broad geographical regions, so that extreme events occurring under different climatic regimes in Africa can be comparable. The first step to construct such an index is to define single hazard indicators. In this first study we focused on extreme dry/wet and heat events, using for their description respectively the well-known SPI (Standardized Precipitation Index) and an index developed by us, called SHI (Standardized Heat-waves Index). The second step consists in the development of a computational strategy to combine these, and possibly other indices, so that the ECI can describe, by means of a single indicator, different types of climatic extremes. According to the methodology proposed in this paper, the ECI is defined by two statistical components: the ECI intensity, which indicates whether an event is extreme or not; the angular component, which represent the contribution of each hazard to the overall intensity of the index. The ECI can thus be used to identify "extremes" after defining a

    Full Text Available This study intends to investigate whether stock returns affect the consumer sentiment. In particular, socially responsible companies are incorporated in the sample in order to capture the specification of socially responsible investors. For this reason, the University of Michigan Consumer Confidence Index is used as a proxy for consumer confidence, while data from Dow Jones Sustainability Index US is employed as a proxy for socially responsible companies for the period 1999-2016. The generalized autoregressive conditional heteroskedasticity model applied and illustrated that stock returns affect positively the consumer confidence. The result has important implications for investors and policy makers.

    Modulation of the refractive index of materials is elementary, yet it is crucial for the manipulation of electromagnetic waves. Relying on the inherent properties of natural materials, it has been a long-standing challenge in device engineering to increase the index-modulation contrast. Here, we demonstrate a significant amount of ultrafast index modulation by optically exciting non-equilibrium Dirac fermions in the graphene layer integrated onto a high-index metamaterial. Furthermore, an ext...
