Ensembled self

Demilitarization Protective Emsemble (DPE), or Toxicological Agent Protective Ensemble Self-Contained (TAPES), used with prior approval from AMC Field Safety Activity. [Pg.442]

Statistical Ensembles A statistical ensemble of states can be constructed by assigning the probability for each of the 2 possible configurations. By an equiprobable ensemble, we will mean a (maximally disordered) collection of states such that each configuration appears with equal probability. A self-organizing evolution under a particular nde modifies the a-priori equal probabilities for states of the ensemble to occur. [Pg.80]

We will refer to the combination of alphabet and probability measure as an ensemble. The self information of the mth symbol in the ensemble is now defined as... [Pg.195]

The most important characteristic of self information is that it is a discrete random variable that is, it is a real valued function of a symbol in a discrete ensemble. As a result, it has a distribution function, an average, a variance, and in fact moments of all orders. The average value of self information has such a fundamental importance in information theory that it is given a special symbol, H, and the name entropy. Thus... [Pg.196]

As an example of self information and entropy, consider the ensemble, U, consisting of the binary digits, 0, and 1. Then if we letp = Pr(l),... [Pg.197]

The self-organization or assembly of nnits at the nanoscale to form supramolecnlar ensembles on mesoscopic length scales comprises the range of colloidal systems. There is a need to understand the connection between structure and properties, the evolution and dynamics of these structures at the different levels—supramolecnlar, molecular, and sub-molecular— by learning from below. ... [Pg.689]

Sol-gel processing forms the basis for various routes employed for the fabrication of a wide diversity of functional materials. To impart a structural organization at various length scales, the syntheses are performed using templates. Most consist of a self-organized ensemble of surfactants and co-polymers [1-10]. They have been successfully applied to control the geometry and dimensions of pores that are periodically arranged as in the initial structures. Mesoporous silica materials of the MCM family, which were first synthesized by a team from the Mobil oil company [11,12], are a well-known example. [Pg.75]

Protective Ensemble and Self-Contained Breathing Apparatus for Rescue Operations During a Terrorist Chemical Agent Incident. August 2003. [Pg.104]

Abstract Chemists may find it difficult to admit that their concepts and opportunities have always been strongly influenced by the available methods for characterization and analysis. Physics, has, of course, the lead when it comes to the visualization of single molecules in real space and to the detection of their specific, not ensemble-averaged properties. The challenge for chemistry is to provide molecules as objects of study which really disclose new concepts of structure and function. This chapter presents a chemical approach toward nanosciences which comprises (i) design and synthesis, (ii) immobilization, often using principles of self-assembly, (iii) visualization, e.g. by scanning probe... [Pg.317]

Model of a supramolecular structure of polymolecular ensembles or clusters, determined by interaction and mutual arrangement of the forming molecules. At this level, the specific mechanisms of supramolecular chemistry, including molecular recognition, self-assembly, etc. [4] can be allocated. In most cases, it is possible to limit this area to objects with the sizes under 1 to 2 nm, since further increase in the sizes admits application of statistical concepts like phase and interphase surface. [Pg.300]

Thermodynamically controlled self-assembly of an equilibrated ensemble of POMs with [AlVWnO40]6 as the main component could act as a catalyst for the selective delignification of wood (lignocellulose) fibers (Figure 13.2) [55], Equilibration reactions typical of POMs kept the pH of the system near 7 during the catalysis that avoided acid or base degradation of cellulose. [Pg.465]

The probabihty distribution/(u,s,f) for the local segment distribution is related to the contribution from the ensemble of segments at s to the total stress. It is calculated self-consistently from the survival probabihty function by letting the surviving tube segments be deformed by the total deformation tensor over their lifetimes, Eftt k... [Pg.245]

While D issuing from these experiments is not strictly the diffusion coefficient of water per se, but rather that of H throughout the ensemble of environments in the hydration microstructure, these authors rationalized that it could in fact be identified with D at both high and low water contents. It should be appreciated that self-diffusion coefficients measured in this way reflect fundamental hopping events on a molecular scale. [Pg.333]

The diffusion coefficient D is one-third of the time integral over the velocity autocorrelation function CvJJ). The second identity is the so-called Einstein relation, which relates the self-diffusion coefficient to the particle mean square displacement (i.e., the ensemble-averaged square of the distance between the particle position at time r and at time r + f). Similar relationships exist between conductivity and the current autocorrelation function, and between viscosity and the autocorrelation function of elements of the pressure tensor. [Pg.405]
