lean manufacturing is a systematic approach to identifying and eliminating wastes (non-value added activities) through continuous improvement by conveying the product at the pull of the customer in pursuit of production. in a more basic term, more value with less work. since lean manufacturing eliminates many of the problems associated with poor production scheduling and line balancing, lean ma...

The dynamics of change in the market force organizations to be ready take up challenges. innovation enterprises is a determinant their development. Implementation technological involves large number important strategic decisions. This publication discusses issue implementing manufacturing enterprise. subject manuscript includes creation comprehensive methodology proceedings. This, turn, issues ...

EAF plants normally consume coal and coke as reactants, alloying elements, or fuel. The price of these materials varies from € 0.20-0.35/kg. This is while nearly 10 million pieces of tires are annually discarded in Iran. The present study shows that scrap tires can be used as a substitute for coal and coke in EAF plants. Thirteen grades of steel including low, medium, and high carbon steels as ...

This paper introduces a perpetual type-2 Neuro-Fuzzy modelling structure for continuous learning and its application to the complex thermo-mechanical metal process of steel Friction Stir Welding (FSW). The ‘perpetual’ property refers to the capability of the proposed system to continuously learn from new process data, in an incremental learning fashion. This is particularly important in industr...

  Background: Nowadays job stress is one of the most important health problems that health and safety professionals are facing with. Much of previous studies have focused on interventions such as stress management and, they have ignored the role of psychosocial factors in occurrence of job stress. This study investigated the mediator role of supervisor support on the association between wo...

aisi 4340 steel is one of the super strong steels that can be selected for different applications. by designing theproper cycles of heat treatment, the optimum microstructure and properties of this steel can be achieved. in thisstudy, different heat treatment cycles were introduced to achieve the optimum microstructure and improve themechanical and magnetic properties of aisi 4340 steel. the re...

ABSTRACT: It is commonly recognized that knowledge is the only source of core competence in the knowledge based companies, but the productivity rate of Knowledge Workers is always Low. Based on Knowledge Workers’ characteristics, in this paper, we seek to identify factors influencing the Productivity of Knowledge Workers, and then strategies present for improvement of theirs Productivity. Final...

We measured emissivity of sample presenting panel of ALMA antenna using Band-10 heterodyne SIS receiver as antenna switching balanced radiometer with 8 GHz instantaneous bandwidth. Receiver noise temperature measured with 80 K/300 K antenna loads was ≈560 K (DSB). Emissivity of the surface is detected at LO frequency about 840 GHz via the imbalance of the antenna switch due to extra reflection ...
