Activation energy of thermal degradation of cotton fabric and coated fabric samples wasdetermined by applying Coats-Redfern method on TG data. Action of intumescent was found concurrent with the process ofdecomposition of cotton fabric on heating. Activation energy of coated fabric with intumescent (165.8 kJ mol^–1) was foundlower than that of uncoated cotton fabric (226.5 kJ mol^–1), which further decreased on inclusion of metals in intumescentformulations (111-127 kJ mol^–1). Char yield for coated fabric with intumescent increased from zero to 11.9% at 600°C. LOIvalue for pure cotton fabric (18%) increased for intumescent-coated fabric (21.8%). <br/> <br/>Page(s): 548-554 http://nopr.niscair.res.in/handle/123456789/4330 Title: Metal cutting process parameters modeling: an artificial intelligence approach <br/> <br/>Authors: Tanikic, Dejan; Manic, Miodrag; Radenkovic, Goran; Mancic, Dragan <br/> <br/>Abstract: This study presents metal cutting process’ parameters modeling (cutting temperature, cutting force, and quality of machinedsurface) using artificial neural networks, and hybrid, adaptive neuro-fuzzy systems. Proposed models can be used for metalcutting process optimization, increasing productivity and reducing manufacturing costs. <br/> <br/>Page(s): 530-539 http://nopr.niscair.res.in/handle/123456789/4329 Title: Incorporating multi-delivery policy and quality assurance into economic productionlot size problem <br/> <br/>Authors: Chiu, Yuan-Shyi Peter; Chiu, Singa Wang; Li, Chun-Yi; Ting, Chia-Kuan <br/> <br/>Abstract: This paper incorporates a multi-delivery policy and quality assurance into an imperfect economic production quantity(EPQ) model with scrap and rework. A portion of nonconforming items produced is considered to be scrap, while other isassumed to be repairable and is reworked in each cycle when regular production ends. Finished items can only be delivered tocustomers if whole lot is quality assured after rework. Fixed quantity multiple installments of finished batch are delivered byrequest to customers at a fixed interval of time. Expected integrated cost function per unit time is derived. A closed-form optimalbatch size solution to the problem is obtained. Two special cases are examined and a numerical example given to demonstratemodel’s practical usage. <br/> <br/>Page(s): 505-512 http://nopr.niscair.res.in/handle/123456789/4328 Title: Composite laminates from jute caddies - an industrial waste <br/> <br/>Authors: Ganguly, P K <br/> <br/>Abstract: This paper describes design and fabrication process of composite laminates from jute caddies as fibrous reinforcement tounsaturated polyester resin (UPR). Tested composite laminates are found suitable in furniture making, construction andautomobile industries, and railway coach building. <br/> <br/>Page(s): 560-562
