Water Manipulation through Curvature Energy on Humidity Microparticles

The electric field created in a curvature energy sensor on air microparticles is used to obtain a temperature-humidity map G:M→SO(2)∪F,by stereo-radially of the sensor design to detect and measure the temperature and humidity of certain local region of the environment space.Likewise,considering the curvature energy as the deviation of any field interaction,even the obstruction to its proper flow,is designed and created a humidity-resistor sensor to the control and optimization of humidity in a space with different gradients of humidity,pressure and temperature in a radial detection and measuring.Then the sensing problem is a problem of free boundary conditions where is satisfied an energy functional of norm ||ξ||_(2),to curvature functions κ,that satisfy in the temperature and humidity function ξ,the change limit condition ξ|_(∂Ω)≤2πξ(r).This carries to that the temperature-humidity sensor must be designed on a length gauge to measure the changes of humidity and temperature in the space.

Autonomous and Mobile Prototype of Curvature Sensor with Remote Reliable Communication of Spectral Curvature

Through the creation and construction of a curvature sensor of accelerometer type, using the spectral curvature concept or curvature energy that measures curvature in Volts/m3, an autonomous and mobile censorship of curvature sensing with reliable data transmission/reception in real time and remote position is designed and constructed considering the spectra of curvature of the measured curvature energy during the advance of the prototype as the normed measure by with β , a constant rationalized parameter according with the required advance of the mobile device in the control scale of their velocity. Likewise, the sensed curvature data are digitalized through wireless interconnectivity using a HC-05 Module with a programmable device that includes logic blocks whose interconnection and functionality can be configured according to the sensor measure in situs. Also an application is planted to the obtaining of an energy plus due to the curvature that could be used in the displacement of a vehicle.

Curvature and Size Effects on Reactivities of Mono-to Octa-vacancies in a(5,5) Single-walled Carbon Nanotube

Defect curvature was developed based on our previously proposed direction curvature theory. Defect curvature, as a universal criterion, was used to identify vacancy formation energies E_f of mono-vacancies to octa-vacancies in a（5,5） tube. An ab initio calculation results showed that E_f decreased with increasing the defect curvature K_（V_s）（s = 1~8）. The structures with removed carbon atoms along zigzag chain or the tubular axis were the most stable in each kind of Vs, because their corresponding K_（V_s） was the largest. In addition, local product structures disturbed the variation rule of E_f as K_（V_s）. There was an odd-even oscillation rule in the smallest E_f among each kind of Vs as the s value and vacancies V2, V4 and V6 were more stable. The stabilities of the related vacancy structures were confirmed by two dissociation processes.

Fast Simulation of Lipid Vesicle Deformation Using Spherical Harmonic Approximation

Lipid vesicles appear ubiquitously in biological systems.Understanding how the mechanical and intermolecular interactions deform vesicle membranes is a fundamental question in biophysics.In this article we develop a fast algorithm to compute the surface configurations of lipid vesicles by introducing surface harmonic functions to approximate themembrane surface.This parameterization allows an analytical computation of themembrane curvature energy and its gradient for the efficient minimization of the curvature energy using a nonlinear conjugate gradient method.Our approach drastically reduces the degrees of freedom for approximating the membrane surfaces compared to the previously developed finite element and finite difference methods.Vesicle deformations with a reduced volume larger than 0.65 can be well approximated by using as small as 49 surface harmonic functions.The method thus has a great potential to reduce the computational expense of tracking multiple vesicles which deform for their interaction with external fields.
