The prototype

Several sensors were used for monitoring the body functions and movements of the user. Sensors monitoring heart rate were attached to the underwear. The rest of the sensors were attached to the suit itself. There are six sensors for measuring the outside temperature and four for measuring the inside temperature. The temperature differences are used for analysing where and in which position the user is, i.e. is he on his back in the snow or is he just lying down by a fire All the electronic devices were attached to the suit itself, including the processor and communications network, with interfaces in 

GSM was selected for data transfer. Instead of using a mobile telephone, the Siemens Cellular Engine M20 was installed as part of the central processing unit. This device is capable of sending and receiving short messages. 

The power supply was the tricky part. After checking all the possibilities, from solar panels to utilizing static electricity, conventional batteries had to be selected. The smallest battery to guarantee power for 24 hours would weigh 600 to 700 g. The battery is rechargeable either at home or from the snowmobile during the drive.

The prototype of verification system of ultrasonic flaw detector developed is described in the scheme given in figure 2. The verification operators performed with the system are as much automated as possible. The level of automatization is limited by the necessity of human reading of information on flaw detector screen, or other operations as manual adjustment of flaw detector settings. 

The CamuS system is intended to be applied mainly in the field of weld inspection, where it is anticipated that the benefits of the analysis and visualisation facilities will be greatest. The specification for the prototype recognised that the system should be applicable to joints where the parent material is between 6mm and 150mm thick, and where the configuration and geometry of the weld preparation are of the types described in prEN1714 (see Figure 2). 

Ultrasonic techniques are an obvious choice for measuring the wall thickness. In the pulse-echo method times between echoes from the outer and inner surface of the tube can be measured and the wall thickness may be calculated, when the ultrasonic velocity of the material is known. In the prototype a computer should capture the measuring data as well as calculate and pre.sent the results. First some fundamental questions was considered and verified by experiments concerning ultrasonic technique (Table I), equipment, transducers and demands for guidance of the tube. 

For the prototype equipment normal immersion inspection in water was selected instead of the delay line solution. 

The final test of the prototype was performed during actual drawing operation. In Figure 6 an example is shown with all four channels recorded during tube drawing. To see the influence of tube velocity the drawing speed was increased every 30 sec, going from zero to 350 tn/sec. 

Evaluation and calibration. A piece of tube was rotated around its own axis during four channel wall thickness mea.surements (Figure 7). The four traces are not identical A rotation apart as should be expected. The calibrations of the four equipment s from the manufacture was not the same. Especially one of the traces has less dynamic than the other three. Based on these observations a dynamic calibration system was suggested using a tube, which could be rotated around its own axis in the measuring system. The values should be verified using traditional mechanical measurement around the tube circumference. The prototype system was permanently installed in the workshop at the production hall. Experimental work was more difficult under such circumstances so our participation in the development work stopped.

The reaction of an atom with a diatomic molecule is the prototype of a chemical reaction. As the dynamics of a number of atom-diatom reactions are being understood in detail, attention is now being turned to the study of the dynamics of reactions involving larger molecules. The reaction of Cl atoms with small aliphatic hydrocarbons is an example of the type of polyatomic reactions which are now being studied [M, 72, 73].

The H4 system is the prototype for many four-elecbon reactions [34]. The basic tetrahedral sfructure of the conical intersection is preserved in all four-electron systems. It arises from the fact that the four electrons are contributed by four different atoms. Obviously, the tefrahedron is in general not a perfect one. This result was found computationally for many systems (see, e.g., [37]). Robb and co-workers [38] showed that the structure shown (a tetraradicaloid conical intersection) was found for many different photochemical transformations. Having the form of a tetrahedron, the conical intersection can exist in two enantiomeric structures. However, this feature is important only when chiral reactions are discussed. 

Here the prototype is H4—as only three spin-pairing arrangements are possible, this system is simple to analyze. It turns out to be very frequently encountered in practice, even in rather complex systems. 

The prototype system for all four electron problem is the H4 system, discussed in Section n. 

The full quantum mechanical study of nuclear dynamics in molecules has received considerable attention in recent years. An important example of such developments is the work carried out on the prototypical systems H3 [1-5] and its isotopic variant HD2 [5-8], Li3 [9-12], Na3 [13,14], and HO2 [15-18], In particular, for the alkali metal trimers, the possibility of a conical intersection between the two lowest doublet potential energy surfaces introduces a complication that makes their theoretical study fairly challenging. Thus, alkali metal trimers have recently emerged as ideal systems to study molecular vibronic dynamics, especially the so-called geometric phase (GP) effect [13,19,20] (often referred to as the molecular Aharonov-Bohm effect [19] or Berry s phase effect [21]) for further discussion on this topic see [22-25], and references cited therein. The same features also turn out to be present in the case of HO2, and their exact treatment assumes even further complexity [18],... 

The DENDRAL project initiated in 1964 at Stanford was the prototypical application of artificial intelligence techniques - or what was understood at that time under this name - to chemical problems. Chemical structure generators were developed and information from mass spectra was used to prune the chemical graphs in order to derive the chemical structure associated with a certain mass spectrum. 

To begin a more general approach to molecular orbital theory, we shall describe a variational solution of the prototypical problem found in most elementary physical chemistry textbooks the ground-state energy of a particle in a box (McQuanie, 1983) The particle in a one-dimensional box has an exact solution... 

In helium we need to look more closely at the consequences of electron spin since this is the prototype of all atoms and molecules having easily accessible states with two different multiplicities. 

Composites. Various composite materials have evolved over the years as a significant class of high performance textile products. The prototype composite is carbon fiber with an epoxy resin matrix for stmctural akcraft components and other aerospace and military appHcations. Carbon fiber composites ate also used in various leisure and spotting items such as golf clubs, tennis rackets, and lightweight bicycle frames. However, other types of appHcations and composites ate also entering the marketplace. For example, short ceUulose fiber/mbbet composites ate used for hoses, belting, and pneumatic tire components. 

The prototype of a pure ethylenediamine is tripeleimamine antazoline [91-75-8] C27H22N2, belongs to the same family of compounds. Several well-known alkylamines in addition to chlorpheniramine are known. Hexchlorpheniramine maleate [2438-32-6] and triprohdine monohydrochloride monohydrate [6138-79-0] an alkenyl derivative, are two examples. 

The synthesis of compounds of general stmcture (44) and (45) is carried out as shown in Eigures 2 and 3. Nafoxidine [1845-11 -0] 52) (38), the prototype dibydronaphthalene lacking an acyl group at C-1, was one of the first compounds found to have higher affinity at the AEBS than at the estrogen receptor (20). 

In order to support the design and fabrication of the prototypical flow train, extensive component testing at the 50 MW level was performed at the CDIF, in addition to testing of electrodes and sidewalls and of coal-fired channels of 20 MW si2e at Textron Defense Systems.
