Construction of the measures

We first note that the coercivity and weak lower semicontinuity of the functional n imply that the problem (2.248) has a (unique) solution The coercivity is provided by the following two inequalities, 

Lemma 2.5. There exists a nonnegative measure jx G such that for 

Consider next the variety V of all functions x such that x = X n Co(fl ), and define a linear and positive functional on V  

By the inequality (2.252), valid for all functions % possessing the property XN 0 in this definition of L is correct. Similar to (Landkof, 1966) the functional L can be extended on Co l,p)- The extended functional is linear and positive, and hence it is continuous. This implies that there exists a nonnegative measure p G such that for all (f G Co l,p) a 

First of all, we note that the function x + (W, 0) is an element of the set K provided that W belongs to the space shown in the Lemma 2.6 formulation and W]v 0 on F,. It should be recalled at this point that X = (IF, w) G K is the solution of the problem (2.248). Hence, substituting X + iW, 0) in (2.248) as a test function yields

In the described techniques, the contact resistance-related issues usually are more typical in the through-plane measurements than in the in-plane measurements. However, surface conductivity measurements are also affected by the contact resistance. These types of experiments are sensitive to undesired electric noise (Tong 2011). Also, the qualities of all electric connections are of great importance. Preconditions for reliable results are careful construction of the measuring unit and sample preparation and quality management of testing procedures with reference probes. The environment has effects on the conductivity values and temperature, but humidity in particular may cause inaccurate results (Boudenne et al. 2011). 

The structure of the section is as follows. In Section 2.8.2 we give necessary definitions and construct a Borel measure n which describes the work of the interaction forces, i.e. for a set A c F dr, the value /a(A) characterizes the forces at the set A. The next step is a proof of smoothness of the solution provided the exterior data are regular. In particular, we prove that horizontal displacements W belong to in a neighbourhood of the crack faces. Consequently, the components of the strain and stress tensors belong to the space In this case the measure n is absolutely continuous with respect to the Lebesgue measure. This confirms the existence of a locally integrable function q called a density of the measure n such that... 

Verifying temperature is the second most important aspect of any compressor operation. As with pressure, the basic form of measurement is a simple temperature gauge. The construction of the gauges is quite varied, ranging from a bimetallic device to the filled systems. When transmis sion is involved, the sensor becomes quite simple, taking the form v)l a thermocouple or a resistance temperature detector (RTD). The monitor does the translation from the native signal to a temperature readout ()r signal proportional to temperature.

Implementability of the corrective measure is concerned with the constructability of the facilities (i.e., site constraints, permitability, equipment availability, and the time it takes to implement and to operate and maintain the facility.)... 

This requirement also makes good sense. A calibration is nothing more than a mathematical model that relates the behavior of the measureable data to the behavior of that which we wish to predict. We construct a calibration by finding the best representation of the fit between the measured data and the predicted parameters. It is not surprising that the performance of a calibration can deteriorate rapidly if we use the calibration to extrapolate predictions for... 

From the foregoing treatment of voltammetry it is clear that for its application sophisticated apparatus is required, especially the electronics moreover, the construction of the electrodes and their mutual positions within the measuring vessel, of adapted size and without or with stirring, requires great care and experience. For this reason it is often advisable to purchase commercial apparatus, which has reached a high level of sophistication and reliability. Here the most desirable property is smooth recording of the voltammetric curve, which necessitates the kind of automation inherently required in the voltammetric method this is different from advanced automation, which is treated in Part C. 

Static measurements (stationary solution). After a coulometric pulse of specific magnitude, the resulting pH step is measured. Repeating the experiment with different pulses allows the construction of the titration curve.
