Deployable structures

Research and development for the km3 NEMO. The construction of km3 scale neutrino telescopes requires detailed preliminary studies the choice of the underwater installation site must be carefully investigated to optimise detector performance the readout electronics must have a very low power consumption the data transmission system must allow data flow transmission, as high as 100 Gbps, to shore the mechanical design must allow easy detector deployment and recovery operations, moreover the deployed structures must be reliable over more than 10 years the position monitoring system has to determine the position of OM within 10 cm accuracy. In order to propose feasible and reliable solutions for the km3 installation the NEMO (NEutrino Mediterranean Observatory) Collaboration has been conducting an intense R D activity on all the above subjects since 1998 [53],... 

In this section I show how embedded lead users deploy structural resources for innovation. One distinct characteristic of embedded lead users lies in linking the corporate R D world with the user world. On the one hand most of the embedded lead users were already users before th joined the firm [e.g. Leisures, 5 SportS] and are still embedded in user networks and environments fe.g. Sport3-5). That means they are in contact with users in their free time and can also draw on these resources external of the firm (Leisure 1, 5]. They discuss ideas especially with other close persons in the network and can assess both the perception of their own and competitor firms (Sportl-5,7 Health 2,4,6 Leisurel, 4,5j.

Folymeric materials exposed to radiation and vacuum, especially under space radiation, are susceptible to space environmental effects, which degrade not only their surface characteristics but also their mechanical properties. For application as structural materials in space, for example, as a base film for deployable structures, understanding of the mechanical properties under radiation and vacuum is particularly important. In this context, the case study described in this chapter has led to the following conclusions ... 

However, there are three broad areas in which top management can be valuably deployed, regardless of individual structure or style. These are... 

The classification structure for PIFs used in this chapter is based on the model of human error as arising from a mismatch between demands and resources which was described in Chapter 1, Section 1.6 (Figure 1.6). In this model demands were seen as requirements for human performance which arise from the characteristics of the process environment (e.g., the need to monitor a panel or to be able to fix a seal in a flange) and the nature of the human capabilities to satisfy these demands (e.g., skills of perception, thinking, and physical action). These demands are met by the individual and group resources of personnel and the extent to which the design of the task allows these resources to be effectively deployed. Where demands exceeded resources, errors could be expected to occur. 

It is clear that to ensure adequate protection of a structure under cathodic protection it is necessary to measure its electrode potential. This can only be achieved by using a reference electrode placed in the same environment as the structure and measuring the e.m.f. of the cell so formed. Since the electrode potentials of different types of reference electrode vary, it is clear that the measured e.m.f. will also vary according to the particular reference electrode used. It follows that the potential measured must always be recorded with respect to the reference electrode deployed, which must always be stated. 

The relative development of the infrastructure to transport C02 is still in its early stages. This is reflected by the low number of existing infrastructures developed to transport C02 from stationary sources into geological structures. Table 1 provides an overview of the current developments for C02 transportation globally. /Ml of these examples have been developed in relation to the EOR technique, where the C02 source is found mainly in natural reserves. In Europe, only a few projects are in operation, but there are plans to deploy an extended C02 pipeline network along Europe to optimise C02 storage structures. 

Q10. You have secured the post of Head of Structural Verification in a small pharmaceutical company (by the strategic deployment of some particularly interesting pictures of the chairman at last year s Xmas party) and you have a capital budget of 350 000 for the year. What do you spend it on ... 

In our work, we opted to deploy the IRES sequences within the 5 UTR of mono-cistronic reporter mRNA (Humphreys el al, 2005 Fig. 6.IB), which were directly transfected into HeLa cells. IRES-containing transcripts were further capped with the nonphysiological A(5/)ppp(5/)G cap structure,... 

The quality of a system is a measure of how closely it meets all its requirements it is an attribute of the design itself. Some qualities can be observed only during runtime because they relate to the dynamic behavior of the deployed system others must be observed during development or maintenance activities because they relate to the design structure itself and how it can be manipulated. 

We can describe this architecture with a combination of a physical model, a component deployment model, and frameworks for the protocols used between these components. Moreover, the four-tier structure itself can be described as a framework.
