A classical theory is developed which calculates the momentum transfer rate constant between an ion and a non-polar molecule. The model takes into consideration the effect of diffraction outside the capture limit on the rate constants. The theory is used to calculate momentum transfer rate constant for Cl- with trans-dichloroethylene and para-difluorobenzene. Theoretical results ...

Live-trapping capture-recapture studies of animal populations with fixed trap locations inevitably have a spatial component: animals close to traps are more likely to be caught than those far away. This is not addressed in conventional closed-population estimates of abundance and without the spatial component, rigorous estimates of density cannot be obtained. We propose new, flexible capture-re...

The Brownie tag-recovery model is useful for estimating harvest rates but assumes all tagged individuals survive to the first hunting season; otherwise, mortality between time of tagging and the hunting season will cause the Brownie estimator to be negatively biased. Alternatively, fitting animals with radio transmitters can be used to accurately estimate harvest rate but may be more costly. We...

Sculpting various 3D facial expressions from a static 3D face model is a process with intensive manual tuning efforts. In this paper, we present an interactive 3D facial expression posing system through 2D portrait manipulation, where a manipulated 2D portrait serves a metaphor for automatically inferring its corresponding 3D facial expression with fine details. Users either rapidly assemble a ...

The “un” in unmarked is somewhat misleading because the package can be used to analyze data from marked animals. The three most common sampling methods that produce suitable data are removal sampling, double observer sampling, and capture-recapture methods. This document focuses on the analysis of capture-recapture data using a class of models known as multinomial N -mixture models (Royle, 2004...

This paper exposes the experimental evaluation of a new technique for the estimation of the instantaneous helical axis of movement of human anatomical joints. The measurement technique, using a six degrees of freedom spatial electro-goniometer, is tested onto a simple revolute joint and onto a subject’s knee. A motion capture system with active optical markers is used at the same time in order ...

hydatidosis is one of the major zoonotic diseases that cause considerable economic losses and public health problems worldwide. the present study was conducted to determine the prevalence of e. granulosus in domestic and wild carnivores and the infection rate of hydatid cyst in slaughtered animals and people in kashan area, central iran. a total of 142 carnivores including 70 stray dogs, 40 jac...

The capture-release of odontocetes allows for tag deployment which provides an opportunity to study behaviour and habitat use by free-ranging animals, as well clinical assessment the animal tissue collection. This review recognises those elements that are common most capture tagging projects, identifies collective knowledge human health concerns during handling guidelines safer techniques. Hand...

Nowadays, honeypots are widely used to divert attackers from the original target and keep them busy within a decoy environment. DeMilitarized Zone (DMZ) is an important zone for network administrators, because many of the services to the public network is provided at this zone. Many of the security tools such as firewalls, intrusion detection systems and several other secu...

in this study, bimodal meso-porous silica (uvm-7) synthesized and fabricated amino silane modified supports were characterized by powder x-ray diffraction (xrd), n2 adsorption/desorption, transmission electron microscope (tem), elemental analysis and titration. capacity of co2 capture on modified bimodal pore structure silica at 70°c was calculated using breakthrough curves; and it was found th...
