Just-in-time (JIT) is an important topic of lean manufacturing and services, focusing on the reduction of the waiting time. In this study, a JIT ubiquitous output system is established based on the application of a handheld intelligent device. The system can be regarded as a location aware service (LAS). The JIT ubiquitous output system starts from the detection of the user’s location and speed...

Modern browsers such as Chrome and Edge deploy constant blinding to remove attacker-controlled constants from the JIT-compiled code. Without such a defense, attackers can encode arbitrary shellcode in constants that get compiled to executable code. In this paper, we review the security and completeness of current constant blinding implementations. We develop DACHSHUND, a fuzzing-driven framewor...

Mobile device is one of the most widespread devices with rendering capabilities now. With the improved performance of the mobile device, displaying 3D scene becomes reality. This paper implements an optimized soft 3D mobile graphics library based on JIT backend compiler, which is suitable for the features of the mobile device. To deeply exploring the advantages of JIT technology, this paper imp...

Just-in-time (JIT) language implementations make heavy use of speculative optimizations, based on assumptions that might become invalid. This requires the implementation to support a bailout mechanism to undo invalidated optimizations. The interaction between assumptions and optimizations is a major source of complexity for JIT implementers: how should optimizations preserve bailout information...

Since the early 1980’s, when Japanese manufacturing firms in a number of industries—including auto, electronics, and machinery—achieved high levels of international competitiveness, Japanese manufacturing practices—particularly those associated with just-in-time manufacturing (JIT)—have attracted considerable attention in North America. Transfer to the United States of JIT is characterized by s...

Beginning in the early 1980' s, a number of US firms followed the pioneering efforts of Shigeo Shingo and Taichi Ohno and adopted Just-In-Time (JIT) manufacturing in an attempt to reshape their manufacturing environments (see Bragg, Duplaga, and Penlesky, 2005). JIT requires that a company have a few reliable suppliers and is believed to enhance productivity and build a leaner manufacturing sys...

One of the major challenges being faced by Database managers today is to manage the performance of complex SQL queries which are dynamic in nature. Since it is not possible to tune each and every query because of its dynamic nature, there is a definite possibility that these queries may cause serious database performance issues if left alone. Conventional indexes are useful only for those queri...

In just-in-time (JIT) production systems, there is both input stock in the form of parts and output stock in the form of product at each stage. These activities are controlled by production-ordering and withdrawal kanbans. This paper discusses a discrete-time optimal control problem in a multistage JIT-based production and distribution system with stochastic demand and capacity, developed to mi...
