Pedestrian safety has recently been considered as one of the most serious issues in the research of traffic safety. This study aims at analyzing the spatial correlation between the frequency of pedestrian crashes and various predictor variables based on open source point-of-interest (POI) data which can provide specific land use features and user characteristics. Spatial regression models were developed at Traffic Analysis Zone (TAZ) level using 10,333 pedestrian crash records within the Fifth Ring of Beijing in 2015. Several spatial econometrics approaches were used to examine the spatial autocorrelation in crash count per TAZ, and the spatial heterogeneity was investigated by a geographically weighted regression model. The results showed that spatial error model performed better than other two spatial models and a traditional ordinary least squares model. Specifically, bus stops, hospitals, pharmacies, restaurants, and office buildings had positive impacts on pedestrian crashes, while hotels were

BACKGROUND This study aims to suggest an approach that integrates multilevel models and eigenvector spatial filtering methods and apply it to a case study of self-rated health status in South Korea. In many previous health-related studies, multilevel models and single-level spatial regression are used separately. However, the two methods should be used in conjunction because the objectives of both approaches are important in health-related analyses. The multilevel model enables the simultaneous analysis of both individual and neighborhood factors influencing health outcomes. However, the results of conventional multilevel models are potentially misleading when spatial dependency across neighborhoods exists. Spatial dependency in health-related data indicates that health outcomes in nearby neighborhoods are more similar to each other than those in distant neighborhoods. Spatial regression models can address this problem by modeling spatial dependency. This study explores the possibility of integrating a

Downloadable (with restrictions)! Abstract We attempt to clarify a number of points regarding use of spatial regression models for regional growth analysis. We show that as in the case of non-spatial growth regressions, the effect of initial regional income levels wears off over time. Unlike the non-spatial case, long-run regional income levels depend on: own region as well as neighbouring region characteristics, the spatial connectivity structure of the regions, and the strength of spatial dependence. Given this, the search for regional characteristics that exert important influences on income levels or growth rates should take place using spatial econometric methods that account for spatial dependence as well as own and neighbouring region characteristics, the type of spatial regression model specification, and weight matrix. The framework adopted here illustrates a unified approach for dealing with these issues.

Alcohol expenditures can provide a different perspective on alcohol use by providing an understanding of the consumer demand for alcohol, the effect of alcohol sales on the economy and the impact on the household budget. Previous studies have focused on alcohol expenditure at the individual-level and have not considered population level factors or the influences of geographical variation. The goal of this study was to examine the socio-economic and built-environment characteristics associated with alcohol expenditures at the small-area level in the City of Toronto. Alcohol expenditure data consisting of purchases in licensed premises and purchases in stores for the year 2010 were retrieved from the Survey of Household Spending (SHS) at the Dissemination Area (DA) level. Socio-economic and built-environment variables were retrieved from the 2006 Census of Canada and DMTI Enhanced Points of Interest (EPOI) data, respectively. Multivariate spatial regression models were used to analyze the ...

METHODS: PBE and PME data for California kindergarten classes from the 2001/2002 to 2013/2014 school years were matched to the locations of schools. Nonspatial clustering algorithms were implemented to group 5147 schools according to their trends in PBE percentages among kindergartners. Cluster assignments were mapped and hotspot analysis was performed to find areas in California where schools sharing trends in PBEs over time were colocated. Schools were further associated both with school-level data on minority enrollment and free and reduced price lunch participation and with charter/private and rural/urban status. Spatial regression was implemented to determine which school-level variables were correlated with PBE rates in the 2013/2014 school year. ...

Appropriate spatiotemporal interpolation is critical to the assessment of relationships between environmental exposures and health outcomes. A powerful assessment of human exposure to environmental agents would incorporate spatial and temporal dimensions simultaneously. This paper compares shape function (SF)-based and inverse distance weighting (IDW)-based spatiotemporal interpolation methods on a data set of PM2.5 data in the contiguous U.S. Particle pollution, also known as particulate matter (PM), is composed of microscopic solids or liquid droplets that are so small that they can get deep into the lungs and cause serious health problems. PM2.5 refers to particles with a mean aerodynamic diameter less than or equal to 2.5 micrometers. Based on the error statistics results of k-fold cross validation, the SF-based method performed better overall than the IDW-based method. The interpolation results generated by the SF-based method are combined with population data to estimate the population exposure to

Multiple logistic regression is precluded from many practical applications in ecology that aim to predict the geographic distributions of species because it requires absence data, which are rarely available or are unreliable. In order to use multiple logistic regression, many studies have simulated pseudo-absences through a number of strategies, but it is unknown how the choice of strategy influences models and their geographic predictions of species. In this paper we evaluate the effect of several prevailing pseudo-absence strategies on the predictions of the geographic distribution of a virtual species whose true distribution and relationship to three environmental predictors was predefined. We evaluated the effect of using a) real absences b) pseudo-absences selected randomly from the background and c) two-step approaches: pseudo-absences selected from low suitability areas predicted by either Ecological Niche Factor Analysis: (ENFA) or BIOCLIM. We compared how the choice of pseudo-absence

Work on visualization tools for area-based spatial data has taken place within the framework of existing statistical and cartographic software, independently of ViSC software such as Iris or AVS (Earnshaw and Wiseman 1992).This may be in part due to the way in which visualization of this type of spatial data has grown out of initial concerns with the lack of spatial analysis facilities in GIS systems. Whatever the reason, it would be extremely interesting to see whether ViSC products could in fact be used for the visualization of area-based data, since they are already available to the academic community and structures have been put in place to support them and this is also suggested as a topic for future research.. ...

Weighting is assigned to sample points through the use of a weighting coefficient that controls how the weighting influence will drop off as the distance from new point increases. The greater the weighting coefficient, the less the effect points will have if they are far from the unknown point during the interpolation process. As the coefficient increases, the value of the unknown point approaches the value of the nearest observational point.. It is important to notice that the IDW interpolation method also has some disadvantages: the quality of the interpolation result can decrease, if the distribution of sample data points is uneven. Furthermore, maximum and minimum values in the interpolated surface can only occur at sample data points. This often results in small peaks and pits around the sample data points as shown in 图 11.41.. In GIS, interpolation results are usually shown as a 2 dimensional raster layer. In 图 11.42, you can see a typical IDW interpolation result, based on elevation ...

A major obstacle in the spatial analysis of infectious disease surveillance data is the problem of under-reporting. This article investigates the possibility of inferring reporting rates through joint statistical modelling of several infectious diseases with different aetiologies. Once variation in under-reporting can be estimated, geographic risk patterns for infections associated with specific food vehicles may be discerned. We adopt the shared component model, proposed by Knorr-Held and Best for two chronic diseases and further extended by (Held L, Natario I, Fenton S, Rue H, Becker N. Towards joint disease mapping. Statistical Methods in Medical Research 2005b; 14: 61-82) for more than two chronic diseases to the infectious disease setting. Our goal is to estimate a shared component, common to all diseases, which may be interpreted as representing the spatial variation in reporting rates. Additional components are introduced to describe the real spatial variation of the different diseases. ...

Integrate powerful spatial analysis and spatial statistics into your predictive modeling, to go beyond points on a map and identify the where, when, and why.

High-content spatial analyses are critical to understanding the structural organization and dynamics of many complex biological processes. Increasing the number of cellular components that can be visualized will help delineate the functions of many interacting and competing cellular pathways. However, the physical limitations of spectral bandwidth and the experimental difficulty of genomic manipulation have hampered traditional approaches to multiplex molecular analyses in both fixed samples and live cells. The programmable and predictable nature of the DNA molecule makes it a tantalizing candidate for an engineering tool to help alleviate some of these limitations. This thesis seeks to harness both the chemical and biological utility of DNA as a building block to multiplex the color and control the number and location of fluorescent reporters in biological samples. First in the context of in situ immunofluorescence imaging of fixed cells or tissues, And second in the context of live-cell ...

Transportation Flows Mapping Using R. The geographic visualization of data using programming languages, and specifically R, has seen a substantial upsurge in adoption and popularity among members of the GIS and data analytics community in recent years. While the learning curve in acquainting oneself with scripting techniques might be steeper than using more traditional and out of box GIS applications, it undoubtedly provides some other benefits such as building customizable processes and handling complex spatial analysis operations. The latter point being imperative for projects containing extensive amounts of data as is often the case with transportation and commuting flows which ordinarily contain considerable amount of records comprising of trips origins and destinations, mode of transport and travel times information. An added interesting perk is that R offers very creative and visually appealing finalized graphical solutions which were one of the motivators behind the choice of technique ...

Spatial interpolation is used to predicts values for cells in a raster from a limited number of sample data points around it. We are studying streaming high-frequency temperature data in Chicago retrieved from Array of Thing (AoT). Kriging is a family of estimators used to interpolate spatial data. This family includes ordinary kriging, universal kriging, indicator kriging, co-kriging, and others (Taken from Lefohn et al., 2005). The choice of which kriging to use depends on the characteristics of the data and the type of spatial model desired. The most commonly used method is ordinary kriging, which was selected for this study. Reference: ...

Most of the approaches for diagnosis or prognosis of deteriorated reinforced concrete (RC) structures are based on two stages: acquiring data (concrete properties, quantitative degradation information), and then predicting the evolution of degradation by using appropriate models. Spatial variability of both properties and degradation processes cannot be neglected in the lifecycle assessment and implies that (i) data should be acquired for a representative part of the concrete surface and (ii) models should be capable of dealing with this variability. However, the assessment and modeling of spatial variability is not a straightforward task particularly when uncertainties affect the measurements or when the number of measurements is limited. The present paper aims at studying the capability of analytical carbonation models to deal with the spatial variability of model inputs in terms of spatial correlation of model outputs. Analytical models are considered herein because they provide practical and usual

In the study of intrinsically stationary spatial processes, a new nonparametric variogram estimator is proposed through its spectral representation. The methodology is based on estimation of the variograms spectrum, here for the isotropic case, which is formulated in terms of solving a regularized inverse problem. We use quadratic programming to obtain the solution. The estimated variogram is guaranteed to be conditionally negative-definite, a key property of variograms. Simulation shows that our estimator is flexible and generally has smaller mean integrated squared error than the parametric estimator under model misspecification.. ...

This paper explores changing socio-environmental interactions in the vegetable producing areas of the Jos Plateau over the decade 1991-2001. It considers the pressures of market forces and ethnic competition and the tensions which arise as interactions between the two are played out in a fragile physical, social and institutional environment. The region has seen a remarkable expansion in irrigated vegetable production, as dry season surveys in 1991 and 2001 attest. Local farmers appear extremely positive in their perceptions of change, pointing not only to expanded production, but also to other improvements, like growing percentages of children in school and improved transport. But behind this rosy view of change there are tensions and a series of unresolved questions which may soon have to be addressed. We examine the changing nature of socio-environmental interactions over the decade and ask whether and how current levels of production can be sustained in the context of a currently largely ...

Sperm cells swim very efficiently when moving upstream against a current and may cooperate whilst doing so, scientists have observed. Researchers found that when sperm cells are faced with a current, they swim in a spiralling motion, rather than in a straight line, and move towards where the current is slowest. This causes the cells to accumulate in groups, swimming in shoals.. This challenges the commonly held belief that sperm cells compete to reach the egg cell first. There could actually be cooperation among these cells that allows them to swim faster collectively, said Dr Jörn Dunkel, lead researcher on the study.. Hundreds of millions of sperm cells enter the oviduct, or Fallopian tube, however only a select few will reach the egg. They have to cover distances more than 1,000 times their length and navigate complex terrain. To try to understand how sperm cells manage this, researchers set up an artificial sperm assault course in the lab. They used a variety of sizes of channels and ...

As game worlds become more complex, game characters need to become more aware of their surroundings. These days, it is no longer sufficiently believable for an agent to merely walk through these environments. Believable movement demands so much more. Characters may now need to jump, climb, duck or vault in order to navigate through their world. Additionally, simply being in a space brings in issues with cover selection, visibility, positioning and other forms of spatial awareness. In the past, this often meant time-consuming manual markup of levels or highly constrained level designs, and it certainly didnt support dynamic environments! This session will show two different architectures being developed - one by Havok and one by MASA - to help automate those spatial issues in a way that is independent of level design ...

The performance of the Weather Research and Forecasting (WRF) model to reproduce the surface wind circulations over complex terrain is examined. The atmospheric evolution is simulated using two versions of the WRF model during an over 13year period (1992 to 2005) over a complex terrain region located in the northeast of the Iberian Peninsula. A high horizontal resolution of 2km is used to provide an accurate representation of the terrain features. The multiyear evaluation focuses on the analysis of the accuracy displayed by the WRF simulations to reproduce the wind field of the six typical wind patterns (WPs) identified over the area in a previous observational work. Each pattern contains a high number of days which allows one to reach solid conclusions regarding the model performance. The accuracy of the simulations to reproduce the wind field under representative synoptic situations, or pressure patterns (PPs), of the Iberian Peninsula is also inspected in order to diagnose errors as a ...

Background: Spatial analysis has been vital in mapping the spread of diseases and assisting in policy making. Targeting diarrhea transmission hotspots is one of the potential strategies for reducing diarrhea cases. This study aimed to examine the spatial-temporal variations and to identify the modifiable determinants of diarrhea while controlling for the spatial dependence in the data. Methods: An ecological study on diarrhea data from DLHS-3 and NFHS- 4 in India. Morans I and LISA were used to detect the spatial clustering of diarrhea cases and to test for clustering in the data. Spatial regression was used to identify the modifiable factors associated with the prevalence of diarrhea. The study comprised of the prevalence of diarrhea among the children below the age of five years (U-5 s) across different states in India. The determinants of diarrhea were obtained using spatial lag models. The software used were GeoDa 1.6.6 and QGIS 2.0. Results: The presence of spatial autocorrelation in ...

This thesis uses a geographic information system (GIS) to demonstrate spatial analysis techniques in order to examine changes to a prehistoric society of Native American Wappo dating from 2450 to 1950 years before present (BP) from the Upper Archaic Period in the Napa Valley of California. This cemetery was excavated by Pacific Legacy Inc., a private cultural resources management firm, in compliance with the National Historic Preservation Act (NHPA) and the California Environmental Quality Act (CEQA) for a flood control project. While Pacific Legacy Inc. analyzed the burials on an individual basis, they did not conduct a spatial analysis. They incorporated their data into a simple spreadsheet to look for patterns. This thesis serves as a complimentary spatial examination of the burials based on spatial data. ❧ The dataset is incomplete as it was not collected using a consistent, systematic methodology. Additional burials related to the dataset had also been removed from the site before ...

In some digital Earth engineering applications, spatial interpolation algorithms are required to process and analyze large amounts of data. Due to its powerful computing capacity, heterogeneous computing has been used in many applications for data processing in various fields. In this study, we explore the design and implementation of a parallel universal kriging spatial interpolation algorithm using the OpenCL programming model on heterogeneous computing platforms for massive Geo-spatial data processing. This study focuses primarily on transforming the hotspots in serial algorithms, i.e., the universal kriging interpolation function, into the corresponding kernel function in OpenCL. We also employ parallelization and optimization techniques in our implementation to improve the code performance. Finally, based on the results of experiments performed on two different high performance heterogeneous platforms, i.e., an NVIDIA graphics processing unit system and an Intel Xeon Phi system (MIC), we show that

This research aimed at establishing whether spatial data and Geographic Information Systems (GIS) can contribute to Strategic Environmental Assessment (SEA). To achieve this, an integrated GISEA approach was developed and applied to a number of spatial planning SEAs in the Republic of Ireland. The practical applicability of the approach was examined, evaluating the potential benefits derived from using spatial data and GIS in SEA and assessing the potential barriers to an effective GIS use. The implementation of the SEA Directive incorporated a new dimension into plan-making by calling for the assessment of potential environmental effects that may derive from implementing a plan. The intrinsic spatial nature of land use plans poses specific requirements on the tools and assessment methods used. GIS - with their capacity to visually display and spatially assess information- have the potential to support SEA processes. Moreover, GIS tools can tackle the spatio-temporal dimensions that conventional

Levels of morbidity varied within and between regions, with several clusters of very high morbidity identified. At the regional level, morbidity was modestly associated with practice funding, with the North East and North West appearing underfunded. The regression model explained 39% of the variability in practice funding, but even after adjusting for covariates, a large amount of variability in funding existed across regions. High morbidity and, especially, rural location were very strongly associated with higher practice funding, while associations were more modest for high deprivation and older age.. ...

The invention concerns a system wherein the spatial values (S1 to Sn) of the physical quantity are represented by measurement pulses (I1 to In) whereof the temporal ordering represents said values. The system comprises a plurality of processing units (U1 to Un) for processing said measurement pulses. They are arranged in at least one row and include each an output (SOR1 to SORn) whereon, during successive processing cycles, a measurement pulse processed therein can be delivered to form the output signal (SU) of the system. The invention is characterized in that each processing unit (U1 to Un) comprises inhibiting means (BI) for, in other units of the row and during a given processing cycle, inhibiting the passage to the outputs (SOR1 to SORn) of said other units respective measurement pulses processed therein and hence preventing them from forming the output signal (SU), if said measurement impulses are temporally ordered later in the given processing cycle than the one processed in the unit concerned.

Abstract , References , Similar Articles , Additional Information Abstract: This article presents a new mathematical framework to perform statistical analysis on time-indexed sequences of 2D or 3D shapes. At the core of this statistical analysis is the task of time interpolation of such data. Current models in use can be compared to linear interpolation for one-dimensional data. We develop a spline interpolation method which is directly related to cubic splines on a Riemannian manifold. Our strategy consists of introducing a control variable on the Hamiltonian equations of the geodesics. Motivated by statistical modeling of spatiotemporal data, we also design a stochastic model to deal with random shape evolutions. This model is closely related to the spline model since the control variable previously introduced is set as a random force perturbing the evolution. Although we focus on the finite-dimensional case of landmarks, our models can be extended to infinite-dimensional shape spaces, and ...

Spatial distributions have played a major role in the epidemiology of several diseases and are essential for the analysis of data involving exposures to environmental pollutants. This chapter explores the process of identifying non-random spatial patterns of disease, and introduces several important statistical techniques (nearest-neighbor analysis, randomization tests, and bootstrap analytic methods) that can be applied to a wide range of other kinds of data. ...

This function computes the theil-sen estimator and the associated P-value, for each pixel over time in a stack of images. The output consists of two rasters (one for the estimators and one for the P-values). It is recommended to use a RasterBrick, which is more efficient in memory management.

Autocorrelation occurs when the residuals are not independent of each other. That is, when the value of e[i+1] is not independent from e[i].. While a residual plot, or lag-1 plot allows you to visually check for autocorrelation, you can formally test the hypothesis using the Durbin-Watson test. The Durbin-Watson statistic is used to detect the presence of autocorrelation at lag 1 (or higher) in the residuals from a regression. The value of the test statistic lies between 0 and 4, small values indicate successive residuals are positively correlated. If the Durbin-Watson statistic is much less than 2, there is evidence of positive autocorrelation, if much greater than 2 evidence of negative autocorrelation. ...

A contactless system and method for estimating the volume, mass or weight of a target animal is provided. First, the target animal is imaged, preferably with a stereoscopic camera. A spatial representation of the target animal is derived from the stereoscopic images. Next, a virtual three-dimensional spatial model is provided, preferably having a shape resembling that of a characteristic of the animal to which the target animal belongs. A software module is provided to reshape the virtual spatial model, using a finite set of independently configurable shape variables, to approximately fit the spatial representation of the individual animal. Finally, the volume, mass or weight of the target animal is estimated as a function of shape variables characterizing the reshaped virtual model.

A medical monitor determines the period of a physiological function, such as blood circulation pulses, by operating a probe that produces an electrical signal which corresponds to the physiological function. The electrical signal is digitized at a given sampling rate to acquire a plurality of signal samples which are stored in a memory. A time scaling factor is adjusted dynamically so that the amount of signal samples being processed does not exceed a maximum limit. The magnitude of the signal samples also may be scaled dynamically. Serial autocorrelation is applied to the signal samples to produce a sequence of summation values. The quantity of summation values from the initial one in the sequence to a peak summation value is determined. The physiological function period is derived from the quantity of summation values, the given sampling rate, and any time scaling factor that was used.
