ITE JOURNAL / AUGUST 2001 BACKGROUND High speeds and rapidly increasing vehicle volumes characterize many of America’s rural, two-lane highways. These features, combined with midto shortradius horizontal curves and limited sight distances, can create hazardous road conditions for the motoring public. These highways may or may not exhibit high accident numbers or rates but are often described by...

It is shown that, in any secant polar stereographic projection, a small circle on a sphere projects into a circle. This property provides a simple relationship between K H , the horizontal component of curvature of a horizonal curve and Kb, the curvature of its projection on a secant polar stereographic map. K H can be computed by subtracting from the map factor times K h the earth’s curvature ...

v. dannon showed that spherical curves in e4 can be given by frenet-like equations, and he thengave an integral characterization for spherical curves in e4 . in this paper, lorentzian spherical timelike andspacelike curves in the space time 41 r are shown to be given by frenet-like equations of timelike andspacelike curves in the euclidean space e3 and the minkowski 3-space 31 r . thus, finding...

Foundation dewatering combined with a waterproof curtain is widely applied to ensure the safety of foundation pit in areas multi-aquifer–aquitard alternative strata. The buried depth diaphragm wall can influence environmental effect due obviously. This paper investigates impact on groundwater drawdown considering anisotropic permeability aquifer. Numerical simulation conducted based an engineer...

Stability analysis of heat transfer (by Conduction, Convection, and Radiation) has been found for a model flow between two horizontal plates, one them is thermally insulated. The stability measure through the neutral curve this shows that an increase buoyancy represented by Gershoff number (Gr) leads to in region, especially considerable value Reynolds R. results indicated effects forces have s...

We have established a novel method to evaluate the redox properties of tea polyphenols by HPLC-coulometric-array analysis. We plotted the quantity of electricity (µC) on the vertical axis and the electric potential (mV), adjusted with the associated palladium reference electrode, on the horizontal axis to provide "quantity versus potential (QP) plot". The patterns of the plots correspond to the...

Horizontal collision correlation analysis (HCCA) imposes a serious threat to simple power analysis resistant elliptic curve cryptosystems involving unified algorithms, for e.g. Edward curve unified formula. This attack can be mounted even in presence of differential power analysis resistant randomization schemes. In this paper we have designed an effective countermeasure for HCCA protection, wh...

This paper is concerned with two themes: imprisoned curves and the b-length functional. In an earlier paper by the author, it was claimed that an endless incomplete curve partially imprisoned in a compact set admits an endless null geodesic cluster curve. Unfortunately, the proof was flawed. We give an outline of the problem and remedy the situation by providing a proof by different methods. Ne...

Devnagari script is the major script of India and is widely used for various languages. In this work we propose a stroke based technique for analyzing handwritten Devnagari characters. After preprocessing the character is segmented in various strokes using our thinning and segmentation algorithm. We propose average compressed direction codes for segmented strokes to classify the strokes as left...
