Abstract We present a practical analysis of the fermion sign problem in fermionic path integral Monte Carlo (PIMC) simulations grand-canonical ensemble (GCE). As representative model system, we consider electrons 2D harmonic trap. find that GCE is even more severe than canonical at same conditions, which, general, makes latter preferred option. Despite these difficulties, show PIMC are still fe...

Sign recognition is an integral part of autonomous cars. Any misclassi€cation of trac signs can potentially lead to a multitude of disastrous consequences, ranging from a life-threatening accident to even a large-scale interruption of transportation services relying on autonomous cars. In this paper, we propose and examine realistic security aˆacks against sign recognition systems for Deceivin...

This paper addresses an aspect of sign language (SL) recognition that has largely been overlooked in previous work and yet is integral to signed communication. This work is the most comprehensive to-date on the recognition of the complex variations in sign appearances due to grammatical processes (inflections). These processes systematically modulate both the temporal and spatial dimensions of ...

Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...

Integral equations can be defined as in which unknown function to determined appears under the integral sign. These have been used many problems occurring different fields due connection they establish with differential equations. Abel?s equation is an important singular and Abel found this from a problem of mechanics, namely tautochrone problem. This some variants it applications heat transfer...

introduction: esophageal cancer is one of the most frequently occurring cancers in iran and having a  high  incidence  rate  among  other  countries.  radiotherapy  is  one  of  the  three  methods  (surgery,  radiotherapy and chemotherapy) for radical or palliative treatment of esophageal cancer. in this method  of treatment, the organs such as heart and spinal cord are regarded as organs at r...
