Directional Distance-Bounding Identification Protocols
Distance-Bounding Public-Key Authentication Directional Antenna
2018/4/19
Distance bounding (DB) protocols allow a prover to convince a verifier that they are within a distance bound. A public key distance bounding relies on the public key of the users to prove their identi...
Multi-Directional Sprint Training Improves Change-Of-Direction Speed and Reactive Agility in Young Highly Trained Soccer Players
COD movements repeated shuttle sprints speed Speedcourt team sport
2016/7/7
The aim of this study was to evaluate the effect of a repeated sprint training with multi-directional change-of-direction (COD) movements (RSmulti) compared to repeated shuttle sprints (RSS) on variab...
Quantitative,Directional Measurement of Electric Field Heterogeneity Within an Enzyme Active Site
Quantitative Directional Measurement Electric Field Heterogeneity Enzyme Active Site
2016/5/25
Extensive structural studies of enzymes have revealed that biological catalysis occurs within sequestered active site crevices, where reacting substrates are surrounded by an anisotropic and chemicall...
We present an algorithm for automatic type checking of logic programs with respect to directional types that describe both the structure of terms and the directionality of predicates. The type checkin...

Study on the Uncertain Directional Relations Model Based on Cloud Model
Spatial analysis Modelling Computer Vision Spatial modelling
2015/12/2
The directional relationship of spatial objects is an important spatial relationship of GIS, which is involved in spatial database query, spatial position, and spatial analysis etc. The directional re...
DEVELOPING A METHOD TO GENERATE INDOORGML DATA FROM THE OMNI-DIRECTIONAL IMAGE
IndoorGML Omni-directional Image Topological Data
2015/11/3
Recently, many applications for indoor space are developed. The most realistic way to service an indoor space application is on the omni-directional image so far. Due to limitations of positioning tec...
MISR (Multiangle Imaging SpectroRadiometer) is an instrument on the EOS Terra platform, which takes
data at nine view angles ranging from 70 deg forward to 70 deg aftward in spectral bands centered a...
DETERMINING THE DIRECTIONAL RESPONSE AND FIELD OF VIEW OF TWO FIELD SPECTRORADIOMETERS
directional response field
2015/9/8
Accurately determining the field of view (FOV) has rarely been considered in detail in field
spectroscopy where spectroradiometer manufacturers?specifications generally lack clarity or
detail. For u...

Directional sensitivity analysis of vegetation indices from multi-angular chris/proba data
Vegetation indices CHRIS/PROBA multiangular
2015/8/20
View angle effects present in vegetation indices are either being seen as unwanted information or as an additional source of
information. However, the magnitude of these angular effects remains for m...
The directional spectrum S(k) [or S(f,θ)] measures the distribution of wave energy in wave number, k, (or frequency, f) and direction. Different contributions to local wave energy, e.g., swell from di...
