The microorganisms can be divided into many groups depending of their need for oxygen. Although there are several groups, two main classes can be distinguished – aerobes and anaerobes. Organisms that cannot use oxygen are called anaerobes. They lack the respiratory system. Aerobes are capa[r]
(e) Derive the complex Poynting theorem in the form V.-[½(r)XH*(r) + 2j < w > = 0 What is <w>? 6. A paradoxical case of Poynting's theorem occurs when a static electric field is applied perpendicularly to a static magnetic fi[r]
during formation of drops of high-viscosity liquids. FEM have also been used in analysis of liquid drops among others. [42-44] However, the representations for the interface shape in these works, which are radially spherical ray, would fail long bef[r]
relatively low top speeds of battery powered robots, forward momentum is not included as a comparison of mobility methods in this book. One last interesting criteria that bears mentioning is the vehicle’s shape. This may not seem to have much bearing on mobility, and indeed[r]
Materials selection enters each stage of the design. The nature of the data needed in the early stages differs greatly in its level of precision and breadth from that needed later on (Figure 2.4, right-hand side). At the concept stage, the de[r]

What is the data modelling? Data modelling is the method used to define and analyze data requirements needed to support the business processes of a project. The data requirements are recorded as a conceptual data model with associated data definitions. In this case study, you will notably discover :[r]
Identification, wall thickness and weights are extracted from ASME B36.10M and B36.19M. The notations STD, XS and XXS indicate Standard, Extra Strong, and Double Extra Strong pipe, respectively. Transverse internal area values listed in “sq.ft” also represent volume in cubic feet per foot[r]
In a "relational" organization of a computerized dictionary with complex interlinked structures, each word acquires its meaning as a result of its position in some of the partitionings created by the formalized relatio[r]
‘adaptive remeshing techniques’ have been employed to resolve the tool’s cutting edge radius. Whereas the ‘Eulerian approach’ tracks volumes rather than mate- rial particles, having the advantage of not needing to rezone any distorted meshes. Moreover the ‘Eulerian technique’ ,[r]
For design problems that can be solved using these techniques, analytic mod- els are ideal. However, the integration of analytic models representing individual systems, each with process characteristics and performance constraints, is not triv- ial. To obtain maximum benefit, these models[r]
An examination of the existing database discloses a number of limitations (Is- kander and Olson, 1992). The data are largely for piles in medium to dense clean sands. For side shear, 63% of the capacity is estimated to come from clean sand, 28% from silty sands and sand[r]
This paper investigates the use of ANNs for the modelling of the magnetic nonlinearity of the SRM. Since this method does not require any prior information regarding the SRM system apart from the input and output signals, it is quite simple and cost effective. The [r]
1.6 Inherent Ill-Posedness A well-posed mathematical problem derived from a physical system must satisfy the existence, uniqueness and stability conditions, and if any one of these conditions is not satisfied the problem is ill-posed. But in[r]
Note also that calling PURGE may cause the user session's message buffer to be overwritten by messages discarded from the pipe. Be sure to send any message packed in the session buffer prior to calling PURGE. Expert technical reviewer Dan Clamage points out that this is because the implementa[r]
