Digital twins in the BT-4 light rail extension project in Bergen. The combination of Digital Twins and BIM methodology has enabled 18 disciplines from 5 countries to manage a better coordination of a new light rail extension in Bergen, Norway. Digital Twins technology continues its progress in the construction sector. Atkins and Cardiff University collaborate on new project for digital replicas in buildings and cities. Women and BIM: an increasingly common combo in construction.

After you read through it once to learn the language, you may find yourself referring back to it to refresh your memory about some of the trickier points of JavaScript.

It is the lowest-level syntax of a language; it specifies such things as what variable names look like, the delimiter char- acters for comments, and how one program statement is separated from the next.

This short chapter documents the lexical structure of JavaScript. Unicode is a superset of ASCII and Latin-1 and supports virtually every written language currently used on the planet. This means that language keywords, variables, function names, and other identifiers must always be typed with a consistent capitali- zation of letters. Because of its close association with client-side JavaScript, this difference can be confusing.

Many client-side JavaScript objects and properties have the same names as the HTML tags and attributes they represent. While these tags and attribute names can be typed in any case in HTML, in JavaScript they typically must be all lowercase. Because you can use spaces and newlines freely in your programs, you can format and indent your programs in a neat and consistent way that makes the code easy to read and understand.

A carriage return, line feed sequence is treated as a single line terminator. They are important for the proper display of some non-English languages and are allowed in JavaScript comments, string literals, and regular expres- sion literals, but not in the identifiers e. To support programmers using this older technology, JavaScript defines special sequences of six ASCII characters to represent any bit Unicode codepoint.

Unicode escapes may appear in JavaScript string literals, regular expression literals, and in identifiers but not in language keywords. These two encodings may look exactly the same when displayed by a text editor, but they have different binary en- codings and are considered different by the computer. JavaScript assumes that the source code it is interpreting has already been normalized and makes no attempt to normalize identifiers, strings, or regular expressions itself.

Regular expression literals are covered in Chapter In JavaScript, identifiers are used to name variables and functions and to provide labels for certain loops in JavaScript code. A JavaScript iden- tifier must begin.

October September RSS Feed. Abstract Numerous studies of the reliability of solder joints have been performed. Most life prediction models are limited to a deterministic approach. However, manufacturing induces uncertainty in the geometry parameters of solder joints, and the environmental temperature varies widely due to end-user diversity, creating uncertainties in the reliability of solder joints. In this study, a methodology for accounting for variation in the lifetime prediction for lead-free solder joints of ball grid array packages PBGA is demonstrated.
