we report the development of different types of oxygen sensors based on yittria-stabilized zirconia (ysz) as a solid electrolyte. the conventional oxygen sensor is a concentration cell with two porous pt electrodes, one of which is exposed to air as a constant (reference) oxygen concentration and the other is exposed to automobile exhaust gas of variable oxygen concentration, depending on the a...
Constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. Due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.On the other hand, ...
Inevitable dominance of lean system concepts on operations world in recent decades, has motivated lots of companies to implement them. But not considering the preferences and limited resources, has caused their failure. This paper aims at presenting a methodology for determining leanness path for companies using their leanness critical success and failure factors. For this first lean indexes im...
Introduction & Objective: Proportion of Waist-to-Hip Ratio (WHR) is an indicator of abdominal obesity, which is supported by some studies but rejected by others. The aim of this study was to examine the accuracy of the WHR and obtain suitable cut- off points for detecting obesity among adult Iranians. Materials & Methods: In this cross-sectional-descriptive study the sample consisted of 19366 a...
This paper presents a comprehensive lean approach, based on Value Stream Management (VSM), which makes it possible to enhance the performance of a service, by spotting and tackling its criticalities. The study is motivated by the growing need to extend lean concepts to the service industry and, on the other hand, by a lack of operating tools capable to support technical staff in this effort. Sp...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
objective: the objective of this study was to investigate the invitro fluoride release of four new self-adhesive resin cements; set (sdi, australia), breeze (pentron, usa), embrace wetbond (pulpdent, usa), g-cem (gc, japan) and to assess the bonding performance of these self-adhesive resin cements for bonding of orthodontic brackets. materials and methods: for fluoride release experiment, six ...
Gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. It also has significant impact on heat transfer. Both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. An arrangement for obtaining a stratified charge, using port injection, is proposed for a ...
Purpose – There is no argument that using games (gamification) is an efficient way of learning in higher education. The questions, though, are which gamification approach is most suitable at that level and how to assess its suitability? This paper aims to attempt to partially answer these two questions, in the context of lean thinking education. Design/methodology/approach – The paper offers an...
