Evaluation Gauge

Wind and density induced currents near the bottom temporarily are very weak. If there were no tidal currents, which are weak but are always ( ) present oxygen depletion in the near-bottom layers of the Baltic Sea probably would occur more frequently. Land uplift and subsidence play a major role in current studies of sea level rise. However, when evaluating gauge data, also the tides have to be taken into account, especially in historical datasets (Liebsch, 1997),...

Ra.m Tensile. A ram tensile test has been developed to evaluate the bond-2one tensile strength of explosion-bonded composites. The specimen is designed to subject the bonded interface to a pure tensile load. The cross-section area of the specimen is the area of the aimulus between the outer and inner diameters of the specimen. The specimen typically has a very short tensile gauge length and is constmcted so as to cause failure at the bonded interface. The ultimate tensile strength and relative ductihty of the explosion-bonded interface can be obtained by this technique. 

The evaluation methods could be direct, e.g., measuring a containment index, or indirect, e.g., measuring pressure loss or velocity distribution. The direct methods are used to measure the performance of a hood or an inlet during periodic preventive maintenance. Indirect methods are used for verifying or checking on a daily basis (routine checks). How often each method is used depends on the availability of instrumentation and qualified personnel, since direct measurement of a hood s performance can be both expensive and difficult. On the other hand, indirect methods are usually easier to use and can sometimes include inexpensive, continuously monitoring instruments (pressure gauges or velocity indicators). 

Perhaps the most widely misunderstood aspect of gauge development is the role of the controlled shock-compression experiment in the development process. It is often stated that the gauges are being calibrated. In fact, it is not possible to calibrate a gauge that must be used over the wide range of conditions and over the wide range of wave profiles encountered and is destroyed in use. Only in special cases of shocks to fixed conditions is the response measured for a gauge in controlled experiments directly a suitable calibration. Even in the direct shock experiment, the controlled shock-compression experiment serves as a shock calibration only if the reproducibility of materials in the sensor is evaluated quantitatively and a persistent reproducible materials source is available. 

There are different techniques to evaluate the quantitative stress level in prototype and production products. They can predict potential problems. Included is the use of electrical resistance strain gauges bonded on the surface of the product. This popular method identifies external and internal stresses. Their various configurations are made to identify stresses in different directions. This technique has been extensively used for over a half century on very small to very large products such as toys to airplanes. There is the optical strain measurement system that is based on the principles of optical interference. It uses Moire, laser, or holographic interferometry (2,3,20). 

As far as topics and learning needs typically addressed during mentoring sessions are concerned, Bernard Wynne states that . .. there seems to be very little that is not discussed and when meetings take place, they are clearly productive. Some of the needs that were discussed can be gauged from the evaluation outcomes reported below. 

The most recently developed mode of economic evaluation is cost-utility analysis (CUA). It is similar to CFA with the important exception that it gauges the impact of an intervention, not in terms of a single... 

Other things being equal, the greater and the more diverse a patient s needs, the broader the range of services likely to be used and the greater the number of outcome dimensions that an evaluation might he expected to need in order to gauge their impact fully. 

All proficiency testing schemes should have a statistical protocol which states clearly how the data will be processed and how laboratory performance will be evaluated. This protocol should also describe how the assigned value for any parameter in a test sample is estimated. This is an important consideration, as the performance of individual laboratories is gauged by comparison with the assigned value. 

Laboratory rotors have been used to evaluate the drag resistance of immersed surfaces as well. The rotational frequency of the innermost cylinder is adjusted to the relevant speed (monitored by a tachometer) and after about 30 minutes of flow stabilisation a 50 Nm strain gauge transducer picks up the torque, M,. All measurements are based on the average of three replicate tests. A sketch of the set-up is shown in Figure 13 details on the set-up and calculations are described in Weinell et al. (2003). 

To gauge the favorability of Mn entering tetrahedral sites in the presence of chemical substitutions that alter the Mn oxidation state, the energy difference between structures such as ps-(LiMn)tet(Li-Sub oaO Sub= Mn and/or substitutional elements) with tetrahedral Mn and 7-Lii/2Mni/4Su7>3/402 Sub = Mn and/or substitutional elements) without tetrahedral Mn have been evaluated over a large range of chemical substitutions.
