Availability of service

The requirement for transport air-conditioning or refrigeration is for an air cooling, air-cooled unit with reliable availability of service. 

To be useful to those concerned with choices in the allocation of health and social care resources, the data for economic evaluations need to be timely, relevant, credible and accurate (Davies, 1998). As a minimum, the costs associated with the interventions should be estimated from activity data, which quantify resources used, and price or unit cost data. Often evidence from well-controlled prospective trials with high internal validity is required to establish whether differences in economic end points are directly attributable to the interventions. However, the economic evaluations of acetylcholinesterase inhibitors estimated costs from retrospective analysis of available datasets Qonsson et al, 1999b), analysis of published literature (e.g. Stewart et al, 1998) and expert opinion (e.g. O Brien et al, 1999 Neumann et al, 1999). This means that it is not clear whether differences in costs were due to the anticholinesterase inhibitors or to other factors such as availability of services in different areas, the living situation of the patient, or disease severity.

Related decisions are where one represents security parameters (see Section 5.2.4, Initialization ), how active attacks on honest users are modeled (Section 5.4.2), and the formalization of availability of service (Section 5.2.7). 

Availability of service means that everybody can carry out transactions of their choice and transactions end within reasonable time. ... 

The requirement that the recipient obtains an output could have been deferred to the availability of service, but connections are easier to handle if the outputs are required to occur simultaneously. The value of this output is usually simply eot . 

The reason for using UNLESS, and not UNTIL, is that it is currently not guaranteed in the structure that sequences never end in the middle of transactions. Anyway, availability of service will be a general requirement that transactions do end. 

Availability of service is the general term for requirements that the system provides service with reasonable delay in particular, deliberate denial of service should be impossible or at least hard. Such requirements are not present in most current definitions of types of signature schemes, because most of them fix a fairly simple stmcture, fi-om which availability of service can easily be seen. 

Availability of service is assumed in addition to the two requirements on disputes, and disputes must be available a little longer than authentication if system termination is considered. 

After a forgery. A stops simulating A and starts a dispute about the forgery, i.e., it inputs all the correct commands at the access points of the interest group and provides the correct connections at the connection-control access point. (And it makes no further inputs.) Before that, it may have to wait until previous transactions at those access points end availability of service guarantees that this happens. 

Availability of service also guarantees that the dispute ends. If the court s output is neither TRUE nor not cooperated , the requirement of the recipient is not fulfilled, because recipient accepts idg, m, id ) had occurred. If it is TRUE or not cooperated , the requirement of the signer is not fulfilled, because signer signs idg, m) had not occurred until the forgery and A made no further inputs since. 

To prevent mischief, one can add a preliminary step where the signer s entity sends an ordinary digital signature on the transaction description to the recipient s entity. The mischief would be that an attacker starts authentication in the name of a signer. The attacker cannot really gain anything by this, but it reduces the availability of service, because the recipient can only use each value i once. 

This property, which will guarantee availability of service in the chosen model, is only defined here, but not always required, because that would exclude the general abstract construction with message hashing, unless the notion of hash functions were modified significantly. However, the constructions with concrete collision-intractable families of hash functions can be modified to have this property (see Section 10.1). 

The algorithm group verification, on input ( 1 , q,p), first tests if I l2 Ipl2 2 len p(lc) this can be done in time polynomial in k. If yes, it continues and tests if > 2 and q I (p-1), and if p and q are prime. As discussed with the factoring assumption, the Rabin-Miller test is used in practice, although it introduces an exponentially small error probability into some properties (but not into availability of service). These tests take time polynomial in the length of q and p, which were already verified to be polynomial in k. 

Availability improvement Clients are sensitive to performance of the system, but they do not perceive the physical structure of the distribution for requests. In other words, the group of networked servers seems to the client like one server. In a distributed processing environment, even if one server breaks, other servers can substitute for the broken server and continue to process its tasks. This can guarantee the high availability of services to the client compared to a host-centric processing environment. 

Preventive Maintenance measures, inspection plans, integrated condition monitoring systems and the availability of service and spare parts at any time over the entire lifetime ensure reliability of an electrolysis system. 

Figure 1.16 Schematic layout of hypothetical process for semi-continuous extraction from bed of particulate solids using a supercritical solvent. The layout shown above for the product recovery and recompression units is not necessarily the most economic one and the design engineer would wish to examine other possibilities. The ideal work requirement, for example, which from Figure 1.19 is 30 joules per gram of CO2 recirculated, could be substantially reduced by condensing the CO2 and recompressing in the liquid state (see chapter 9). However, the subsequent return of the CO2 stream to the extraction temperature would involve an appreciable heat load. It might also be preferable to operate the separator under sub-critical conditions. The economic consequences of these and other modifications would need to be examined in the light of the requirements of the particular process and the availability of services on the plant site.

A large and ever-increasing selection of infrared spectrophotometers is available to the analyst. This section will summarize some of the distinguishing factors in these instruments and provide some basis for interpreting manufacturers specifications. Final selection of a particular instrument depends not only on the best match between the specifications and the requirements of the particular laboratory, but also on many factors that lie beyond the scope of this chapter. These include the personal confidence of the analyst in the manufacturer the availability of service, spare parts, and supplies delivery time cost ... 

Problems with physical access have broad ramificatiorrs for people with disabilities and impede their ability to avail of services in other areas such as food rations, healthcare, education, and vocational opportunities. A closer look at each of these areas reveals additional barriers for displaced persons with disabilities. 

Order capture processes enter customer s request for products. It does so using a standard interface platform. Order validation creates the library of business and technical rules that can be used to determine if an order is valid and should be accepted for further processing. For example, business rules define possible actions on customer s credit limit and/or the contractual terms. Technical rules define availability of services needed to complete the order in the customer s premises. Order decomposition provides a mechanism to generate multiple sub-orders based on the product definition (product decomposition) or based on the delivery location (work order decomposition). For example, a customer may order a broadband...
