Industrial steel fabrication encounters numerous difficulties in having efficient production. These are usually caused by the presence of bottlenecks that not easily identified using traditional methods. Value Stream Map (VSM) is a lean tool can be used to identify process inefficiencies and plan minimize non-value-added activities. However, VSM designed applied non-repetitive work environment ...

BACKGROUND Quality improvement within health and social care facilities is needed and has to be evidence-based and patient-centered. Value Stream Mapping, a method of Lean management, aims to increase the patients' value and quality of care by a visualization and quantification of the care process. The aim of this research is to examine the effectiveness of Value Stream Mapping on structure, pr...

This paper establishes a stylized fact: in a cross-section of American consumers, consumption is an extremely poor predictor of future income. The PSID now contains the majority of the lifetime income stream for an early cross-section of consumers. Under the assumption that consumption is a function of the expected present value of income, I invert this function and compare the realized present...

A fundamental diiculty in automatic formal veriication of nite-state systems is the state explosion problem { even relatively simple systems can produce very large state spaces, causing great dii-culties for methods that rely on explicit state enumeration. We address the problem by exploiting structural symmetries in the description of the system to be veriied. We make symmetries easy to detect...

introduction: one of the reasons people do not refer to dental offices is anxiety over pain. preoperative education is one of non-pharmacological methods to treat anxiety. this study evaluated the effect of preoperative education on decreasing state and trait anxiety in patients referring to a dental surgery center. materials and methods: the subjects in this clinical trial consisted of all the...

Matching frictions imply the value of being unemployed depends on the stream of future UI payments. The sooner a worker's eligibility to UI payments expires, the lower the value to remaining unemployed. In the moral hazard literature, declining UI payments are used to trigger greater search e®ort. Here declining UI payments undermine the worker's bargaining position and (partially) corrects the...

Linked Stream Data, i.e., the RDF data model extended for representing stream data generated from sensors social network applications, is gaining popularity. This has motivated considerable work on developing corresponding data models associated with processing engines. However, current implemented engines have not been thoroughly evaluated to assess their capabilities. For reasonable systemati...

This paper presents an investigation of current state practice of the Manufacturing Engineering discipline for concurrent manufacturing planning. The research adopted a case study approach and has been conducted at a globally operating manufacturer of aerospace products. The investigation establishes how information systems and the cross-functional teaming enable integrated processes for planni...

Watermarking is known to be a very difficult task. Robustness, Distortion, Payload, Security, Complexity are many constraints to deal with. When applied to a video stream, the difficulty seems to be growing in comparison to image watermarking. Many classical non malicious manipulations of a compressed stream may suppress the embedded information. For example, a simple re-compression of a DVD mo...
