OBJECTIVES The objective was to determine whether just-in-time (JiT) instructions increase successful tourniquet application by laypersons. METHODS This was a randomized pilot study conducted in August 2014. The study occurred at the Uniformed Services University campus in Bethesda, Maryland. A total of 194 volunteers without prior military service or medical training completed the study. The...

The Java virtual machine (JVM) is usually implemented with an interpreter or just-in-time (JIT) compiler. JIT compilers provide the best performance, but must be substantially rewritten for each architecture they are ported to. Interpreters are easier to develop and maintain, and can be ported to new architectures with almost no changes. The weakness of interpreters is that they are much slower...

Though increasing usage of just-in-time (JIT) practices is reported, academics—including Shapiro at Harvard Business School, Karmarkar at UCLA (Anderson) and Cusumano at MIT (Sloan)—as well as a number of practitioners have warned against the unrestricted pursuit of just-in-time practices. They suggest that pure JIT is appropriate only for limited economic environments, that it is ineffective i...

Function duplication is widely used by JIT compilers to efficiently implement dynamic languages. When the source language supports higher order functions, the called function’s identity is not generally known when compiling a call site, thus limiting the use of function duplication. This paper presents a JIT compilation technique enabling function duplication in the presence of higher order fun...

JavaScript is nowadays the lingua franca of web browsers. This programming language is not only the main tool that developers have to implement the client side of web applications, but it is also the target of frameworks such as Google Web Toolkit. Given this importance, it is fundamental that JavaScript programs can be executed efficiently. Just-in-time (JIT) compilation is one of the keys to ...

In production processes, just-in-time (JIT) completion of jobs helps reduce both the inventory and late delivery of finished products. Previous research which aims to achieve JIT job completion mainly worked on static scheduling problems, in which all jobs are available from time zero or the available time of each job is known beforehand. In contrast, dynamic scheduling problems which involve c...

The Covid-19 pandemic and other recent disruptions in the early 2020s led to sections business press blaming just-in-time (JIT) practices for operational failings. Consequently, there are calls moving away from JIT toward holding more inventory as preparation against future disruptions, which is referred just-in-case. academic community also divided. Some scholars argue that not resilient, whil...

JavaScript has become one of the most popular programming languages. It powers various popular websites and has become the de facto web assembly language. The efficiency of the JavaScript engines become crucial to the success of most web applications. Most modern JavaScript engines use just-in-time (JIT) compilation to translate parts of JavaScript code into efficient machine code at runtime. D...

Dynamically typed programming languages such as JavaScript and Python defer type checking to run time. In order to maximize performance, dynamic language VM implementations must attempt to eliminate redundant dynamic type checks. However, type inference analyses are often costly and involve tradeoffs between compilation time and resulting precision. This has lead to the creation of increasingly...
