  • Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.

  • The other routing protocols have been proposed in WSN to improve QoS other restrictions such as the delay. The problem here is that the complexity of the routing protocol significantly increased with integration of more than one QoS parameter. Indeed, define a QoS route meets two or more countries not limited correlation (eg, delay, and bandwidth) is an NP- complete problem (Mellouk et al, 2007), because many limitations optimal path problem can not be solved in polynomial time.

  • Regions and gates can be made to better separate and analyze populations of interest. Furthermore, on the basis that the dyes used to stain cells have overlapping emission spectra, the compensation is normally made to reduce interference. While basic instruments may only permit the simultaneous collection of two or three fluorescence signals, the more complex and expensive research instruments mean that it is possible to obtain more than 14 parameters (Winson & Davey, 2000; Chattopadhyay et al., 2008) depending on the laser equipment utilized.

  • The skin plays an important role in maintaining the integrity of the living organism while allowing the interaction of the organism with its environment. To fulfill these functions, mechanical stability is as important as flexibility. The mechanical properties of skin are very diverse depending on the anatomical location, and they evolve throughout life from the fetus to old age. Both genetic and acquired skin diseases modify skin biomechanics, as do intrinsic and photoaging.

  • The control properties of biochemical pathways can be described by control coefficients and elasticities, as defined in the framework of metabolic control analysis. The determination of these parameters using the traditional metabolic control analysis relationships is, however, lim-ited by experimental difficulties (e.g. realizing and meas-uring small changes in biological systems) and lack of appropriate mathematical procedures (e.g. when the more practical large changes are made).

  • Although assembling of a number of device parts is not really a problem in the macroscaleworld, it needs to be delicately handled in themicroscaleworld. Themain point is the adjustment and alignment accuracy of the parts. Moreover, problems of sealing, fixation and bonding technology may also occur depending on the material and the parameters of the designated process of the device.Depending on the surface quality and the bonding technology applied, aligning errors may reach similar dimensions compared to themicrostructure itself. An example of the same is shown in Figure 1.11.

  • The tribology term comes from the Greeks of the words ‘’ tribos’’ meaning ‘’ friction ‘’, and ‘’logos’’ meaning ‘’ law ‘’. Therefore Tribology is defi ned as “ a science which studies surfaces moving one compared to the other “ and also a fi eld of science studying lubrication, friction, and wear.

  • About a decade ago, the elastic properties of a single chromatin fiber and, subsequently, those of a single nucleosome started to be explored using optical and magnetic tweezers. These techniques have allowed direct mea-surements of several essential physical parameters of individual nucleo-somes and nucleosomal arrays, including the forces responsible for the maintenance of the structure of both the chromatin fiber and the individual nucleosomes
