Compatibility code

Backwards compatible multichannel coding adds the option of forward and backwards compatible coding of multichannel signals including the 5.1 channel configuration known from cinema sound. 

Those derived from the adjacency matrix the total adjacency index, the Zagreb group indices, the Randic connectivity index, the Platt index, the compatibility code, and the largest eigenvalue index ... 

Using a Terminal. Dial-up terminals may also be used to access a vendor s databases however, the terminal, personal computer, word processor, or microcomputer must all be compatible with specific functionaHties. Eor example in order to access the DIALOG service these must all be TTY compatible have ASCII coding and be compatible for asynchronous transmission in full-duplex mode for communication through DIALNET,... 

Electiical classification. Article 500 of the National Electric-Code provides for the classification of the hazardous nature of the process area in which the measurement device will be installed. If the measurement device is not inherently compatible with this classification, suitable enclosures must be purchased and included in the installation costs. 

Lined vessels are used for many applications. Any type of lining can be used in an ASME Code vessel, provided it is compatible with the metal of the vessel and the contents. Glass, rubber, plastics, rare metals, and ceramics are a few types. The hning may be installed separately, or if a metal is used, it may be in the rorm of clad plate. The cladding on plate can sometimes be considered as a stress-carrying part of the vessel. 

For each fold one searches for the best alignment of the target sequence that would be compatible with the fold the core should comprise hydrophobic residues and polar residues should be on the outside, predicted helical and strand regions should be aligned to corresponding secondary structure elements in the fold, and so on. In order to match a sequence alignment to a fold, Eisenberg developed a rapid method called the 3D profile method. The environment of each residue position in the known 3D structure is characterized on the basis of three properties (1) the area of the side chain that is buried by other protein atoms, (2) the fraction of side chain area that is covered by polar atoms, and (3) the secondary stmcture, which is classified in three states helix, sheet, and coil. The residue positions are rather arbitrarily divided into six classes by properties 1 and 2, which in combination with property 3 yields 18 environmental classes. This classification of environments enables a protein structure to be coded by a sequence in an 18-letter alphabet, in which each letter represents the environmental class of a residue position.

The overall design process depends on the use of codes of practice and specifications, and to an increasing extent on computer-based techniques. The potential cost of delay is therefore a strong incentive to the use of standard solutions, compatible with the codes of practice , and to develop ways of using the computer to provide corrosion information and knowledge, or to improve prediction of corrosion behaviour. Note that both points relate to the use of existing knowledge, in the sense of an important conclusion of the Hoar Report. ... 

The modern discipline of Materials Science and Engineering can be described as a search for experimental and theoretical relations between a material s processing, its resulting microstructure, and the properties arising from that microstructure. These relations are often complicated, and it is usually difficult to obtain closed-form solutions for them. For that reason, it is often attractive to supplement experimental work in this area with numerical simulations. During the past several years, we have developed a general finite element computer model which is able to capture the essential aspects of a variety of nonisothermal and reactive polymer processing operations. This "flow code" has been Implemented on a number of computer systems of various sizes, and a PC-compatible version is available on request. This paper is intended to outline the fundamentals which underlie this code, and to present some simple but illustrative examples of its use. 

To carry out a numerical solution, a single strip of quadrilateral elements is placed along the x-axis, and all nodal temperatures are set Initially to zero. The right-hand boundary is then subjected to a step Increase in temperature (T(H,t) - 1.0), and we seek to compute the transient temperature variation T(x,t). The flow code accomplishes this by means of an unconditionally stable time-stepping algorithm derived from "theta" finite differences a solution of ten time steps required 22 seconds on a PC/AT-compatible microcomputer operating at 6 MHz. 

Explosive chemicals tend to be governed by separate legislation, e.g., in the UK, The Classification and Labelling of Explosives Regulations 1983. These require the HSE to classify any explosive before it may be supplied. Under the scheme, explosives are labelled according to a classification based on hazard division (Table 12.7), and on compatibility (Table 12.8), which takes into account their sensitivity, explosivity and chemical nature. Labels are diamond shaped the top half is reserved for the pictograph and division number, the bottom half shows the hazard code and the classification number. Figure 12.1 shows the label for Class 1, Division 1.1, 1.2 or 1.3 explosive. 

An excellent way to export information from SAS to another SAS user is with PROC CPORT. PROC CPORT creates an operating system-independent SAS transport file that can hold data sets as well as SAS programs, permanent format catalogs, and other SAS catalogs. Note that PROC CPORT files are not backward compatible with older versions of SAS, so a transport file created by PROC CPORT in SAS 9 cannot be read by SAS 8. Here is some example code showing how to place all of the SAS data sets and permanent formats from a libref called library into a SAS transport file called mytrial.xpt. ... 

The ideal PrHA team has an intimate knowledge of the standards, codes, specifications, and regulations applicable to the process. Team members must be compatible, and the team leader must be able to manage the team and the study. 

It is often convenient to get that compatible implementation by subclassing from another class, but it never matters to the client whether or not we subclass we could just as well cut and paste the methods, delegate, or code it all ourselves. In Smalltalk the only check is a runtime verification that each message sent is supported. 

Modifications to code, including bug fixes, that can override or patch existing code in another package (with certain restrictions ensuring backward compatibility). 

A new version is backward-compatible from a user s point of view. The new material is only an extension of the old. If the contents are program code, then the code may be different, but it should at least meet the previous version s spec. 

It may be legacy in the sense that there is a lot of code and data already built for a given application or only in the sense that compatibility constraints force the use of more-traditional technology such as RDBs. 

When a GC 16A series gas chromatograph is used as the core, various laboratory-automation-oriented attachments such as bar-code reader and a magnetic-card reader become compatible a labour-saving system can be built, in which the best operational parameters are automatically set. Each satellite gas chromatograph (GC 14A series) operates as an independent instrument when a keyboard unit is connected.
