Tactile perception of spatially distributed vibratory stimuli on the fingerpad
Using a pin-array type tactile display as a stimulator of the finger pad, a psychophysical study was conducted on the vibrotactile perception. The passive touch with vibratory stimuli in the low frequency could be an alternative of the active touch for the presented stimuli: polygons, round shapes …

An efficient multinomial sampling algorithm for spatially distributed stochastic particle simulations
This study develops a new particle-resolved method (PGM) for stochastically simulating the transport of particles by advection and diffusion processes. This particle-resolved method is based on a multinomial sampling algorithm which calculates the number of particles transferred between adjacent …

Optimizing Random Access for Information Freshness in Spatially Distributed Wireless Networks
… (AoI) in wireless networks where nodes use a spatially adaptive random access scheme to send status updates to a central base station. We show that the set of achievable AoI in this setting is convex, and design policies to minimize weighted sum, min-max, and proportionally fair AoI by setting …

Age of information for broadcast and collection in spatially distributed wireless networks
… and collecting timesensitive data to and from spatially distributed nodes in the presence of wireless interference. The Age of Information (AoI) is the time that has elapsed since the mostrecently delivered packet was generated, and captures the freshness of information. In the context of …

Hydrologic Evaluation of Low Impact Development Using a Continuous, Spatially-Distributed Model
… ponds partially address. LID analysis takes a spatially lumped approach, based on maintaining the predevelopment Curve Number and time of concentration, precluding consideration of the spatial distribution of impervious areas and Integrated Management Practices (IMP's), runoff-runon processes, …

Development and Evaluation of a Gis-Based Spatially Distributed Unit Hydrograph Model
… The objective of this research was to develop a spatially distributed unit hydrograph (SDUH) model that directly reflects spatial variation in the watershed in generating runoff hydrographs. The SDUH model is a time-area unit hydrograph technique that uses a geographic information system (GIS) to …

Distributed MAC protocol for networks with multipacket reception capability and spatially distributed nodes
… layer. However, we show that in networks with spatially distributed nodes, reusing MAC protocols originally designed for narrow-band systems (e.g., CSMA/CA) is inefficient. It is well known that when networks with spatially distributed nodes operate with such MAC protocols, the channel may be …

Predictions of produced water quality and quantity for spatially-distributed wells in Niobrara formation
… of water handling and treatment facilities in a spatially heterogeneous shale oil and gas field. The information can also be used to model availability of water resources and plan long term recycling strategies for augmenting regional surface water supplies. This study describes protocols to …

A neural network-based method for evaluating a spatially distributed parameter field: An application in groundwater remediation under uncertainty
Uncertainty due to spatial variability of hydraulic conductivity is an important issue in the design of reliable groundwater remediation strategies. Using groundwater management models based on a stochastic approach to groundwater flow, where the log-hydraulic conductivity is represented as a …

Spatially distributed bioaccumulation risk analysis: a GIS-based tool and a case study of polychlorinated biphenyls in the Great Lakes
… Evaluation Screening Tool) to perform spatially distributed bioaccumulation risk analyses. Estimating bioaccumulation risk is important to help predict potentially adverse e ffects from contaminants on ecosystems and human health, which are key factors in the development of sound public …

Development and evaluation of a watershed-scale hybrid hydrologic model
<p>A watershed-scale hybrid hydrologic model (Distributed-Clark), which is a lumped conceptual and distributed feature model, was developed to predict spatially distributed short- and long-term rainfall runoff generation and routing using relatively simple methodologies and state-of-the-art spatial …

Design and Implementation of a Distributed Tdoa-Based Geolocation System Using Ossie and Low-Cost Usrp Boards
… specification allows for these components to be distributed among a set of computing hardware and to be connected by standard interfaces. This research aims to build a spatially distributed SCA application for the Open Source SCA Implementation: Embedded (OSSIE) implementation using low-cost …
