Geospatial aspects of catchment hydrology [PDF]

open access: yes, 2004
The catchment is a fundamental unit of study in hydrology. It is normally well defined topographically, can be studied as a series of nested units (larger catchments are made of many smaller sub-catchments), and is an open system for measuring inputs ...

Analysis of Narrow s-channel Resonances at Lepton Colliders

open access: yes, 1999
The procedures for studying a single narrow s-channel resonance or nearly degenerate resonances at a lepton collider, especially a muon collider, are discussed.

A multi-channel real-time detection method for tunnel boring machine cutter wear based on Chirped Fiber Bragg Gratings

open access: yesAIP Advances, 2019
We propose a multi-channel real-time detection method for tunnel cutter wear of boring machine (TBM) based on Chirped Fiber Bragg Gratings (CFBG). We designed and fabricated the real-time wear detection sensor and the multi-channel real-time demodulation

A Two-Step Quantum Direct Communication Protocol Using Einstein-Podolsky-Rosen Pair Block

open access: yes, 2003
A protocol for quantum secure direct communication using blocks of EPR pairs is proposed. A set of ordered $N$ EPR pairs is used as a data block for sending secret message directly.

INVESTIGATING THE ROLES OF MECHANORECEPTIVE CHANNELS IN TACTILE APPARENT MOTION PERCEPTION: A VIBROTACTILE STUDY [PDF]

open access: yes, 2018
Tactile apparent motion (TAM) is a perceptual phenomenon in which consecutive presentation of multiple tactile stimuli creates an illusion of motion. Employing a novel tactile display device, the Latero, allowed us to investigate this.

Top quark pair cross section measurement at ATLAS [PDF]

open access: yes, 2008
An accurate determination of the top quark pair production cross section at the LHC provides a valuable check of the Standard Model. Given the high statistics which will be available (about one top quark pair per second, at a luminosity of 10^33 cm^-2 s^-

Bias current dependence of spin accumulation signals in a silicon channel detected by a Schottky tunnel contact

open access: yes, 2011
We study the electrical detection of spin accumulation at a ferromagnet-silicon interface, which can be verified by measuring a Hanle effect in three-terminal lateral devices.

А Меаsuring Method for Gyro-Free Determination of the Parameters of Moving Objects

open access: yesMetrology and Measurement Systems, 2016
The paper presents a new method for building measuring instruments and systems for gyro-free determination of the parameters of moving objects. To illustrate the qualities of this method, a system for measuring the roll, pitch, heel and trim of a ship ...
