It causes path loss and finally limits coverage area. Empirical models are employed in network planning, most especially for conducting feasibility studies. This research work embraces two empirical models: Friis and Okumura-Hata and are used to predict broadcast signal strength for Akure, Ondo State, Nigeria. Measurement results of signal strength in UHF band taken in the three routes of Akure were compared with the predicted results using the empirical models. However, in this research paper, a modified Okumura-Hata model was developed and can be used for radio communication system design in Akure metropolis. <#LINE#> @ @ Saunders S., Antennas and Propagation for Wireless Communication Systems, Wiley409 (2000) @No $ @ @ Olorunnibi E.D., Path Loss Prediction Model for UHF Radio Waves in Akure Metropolis, A dissertation, Electrical and Electronic Engineering of the Federal University of Technology, Akure, Nigeria (2010) @No $ @ @ Vijay Garg Wireless Communications and Networking, Morgan Kaufmann Publishers, San Francisco, CA 94111(2007) @No $ @ @ Serpil A.

But, India is facing incremental challenges such as rising customer’s expectation, widening customer-base of existing ones, fluctuating demand, taxation, lack of infrastructure and intense competition. Thus, India needs to be more efficient in her key activities or processes to cope with the challenges. Lean manufacturing could be a solution in order to improve the performance in this competitive globalized market where uncertainty is prevalent. The purpose of this study is to examine the techniques of adopting lean, the tools implemented, the motivators, obstacles and challenges in adopting lean in Indian Electronics manufacturing industry. The data collection was conducted through a structured questionnaire both online and off line, observations from the past studies, company reports and visits to the companies were also done. The results show that the degree of lean implementation in Indian electronics manufacturing industry is still nascent. So, the concerned authorities should play a considerable role and frame some policies to promote lean manufacturing. Future research would consider doing analysis in a more number of organizations as this will reflect the true index.<#LINE#> @ @ 2012 Indian Electronics Story a 'Page Turner'? 05 Jan(2012) @No $ @ @ Empfasis - Lean Manufacturing for Electronics (2008) ; www.empf.org/empfasis/2008/Jun08/lean.htm @No $ @ @  Tapping D., Luyster T. and Shuker T., Value Stream Manage, New York, Productivity Press (2002) @No $ @ @ Lee-Mortimer A., A continuing lean journey: An electronic manufacturer’s adopting of Kanban.

<#LINE#>Important aspects of Inter turn Insulation in High Voltage Motors<#LINE#>Puranik@K.K.<#LINE#>15-18<#LINE#>4.ISCA-RJEngS-2013-043.pdf<#LINE#> Singhania University, Pacheri Bari, Rajsthan, INDIA<#LINE#>17/3/2013<#LINE#>2/4/2013<#LINE#>  High voltage induction motors play a vital role in reliable operation and performance of process industries and utilities of power plants. H.V. motors are used to drive boiler feed pumps, primary air fan, cooling water pumps, induced and forced draught fan drive motors, mill motors and other utility operation in thermal power plant. Induction motors have been the most popular electric motors in the family of motors. The failure data on large induction motors indicate that the stator related failure account for about 37% of the total failure. Stator insulation failure results from either the failure of turn to ground insulation or turn to turn insulation which ultimately leads to main insulation failure. The inter turn insulation in a motor is a weak spot, soundness of inter turn insulation is crucial for reliability of motor. The present paper  is aimed to identify the occurrence  of inter turn faults within the coils and turns of the stator winding, requirement of inter turn insulation details of inter turn insulation systems and impulse voltage withstand capacity of  inter turn  insulation., precautions to be taken during manufacture and  assembly of winding. <#LINE#> @ @ Popescu Mirecea, Induction motor modeling for vector control purpose.

Full factorial Design of Experiments (DOE) has been adopted to estimate the number of runs and the combination of independent variables for each run. The data obtained from the experimentation was analyzed using Taguchi Method. The analysis indicate that material thickness is the main contributing parameter for the variation in the surface roughness of the drilled hole compared to other parameters and the least contributing parameter is spindle speed. The analysis results reveal that, except the spindle speed, the rise in the level of the other independent parameters increases the surface roughness. But as spindle speed increases, the surface roughness decreases. The correlation between thrust force and the surface roughness is also predicted. The optimum combination of process parameter settings has been found out using the integration of Taguchi method and Response Surface Methodology (RSM).  <#LINE#> @ @ Jain S., Yang D. and C.H., Delamination-free drilling of composite laminates Trans.

Ten independent fiber orientations are considered and both analytical and finite element solutions are presented using macro mechanics approach of analysis of orthotropic lamina and by using ANSYS10 finite element package. It is observed that the stress intensity at the crack tip increased gradually from zero degrees to seventy degrees and showed a decline after 70 degrees. It is observed that the variations in the load carrying capacity of matrix phase around the discontinuous fibers at the crack tip for different fiber orientations influenced the stress intensity variations. The results obtained from analytical and finite element approaches showed good congruence.  <#LINE#> @ @ Astrom B.T., Manufacturing of polymer composites, Chapman and Hall publications, London, (1992) @No $ @ @ Mallick P.K., Fiber reinforced composites: materials, manufacture and design, Marcel-Dekker, edition , (1993) @No $ @ @ Balaguru I., Senthil Kumar S., Sridhar K., Investigation of stealth strategies in coir fiber reinforced polymer matrix composites, Research Journal of Material Sciences,1(1), 6-10 (2013) @No $ @ @ Sankaran Apurva, Bhuvaneswari B., Maheswaran S., Santhi A.S., Nagesh R., Iyer, Application of Multi layer composites in construction and their future challenges, Research Journal of Material Sciences,1(3), 12-18, (2013) @No $ @ @ Halpin J.C. and Tsai S.W., Effects of environmental factors on composite materials, Airforce technical Report AFML-TR-67-423,Wright Aeronautical labs, Dayton, OH, (1967) @No $ @ @ Halpin J.C., Stiffness and expansion estimates for oriented short fiber composites, Journal of Composite Materials,3,732-734 (1969) @No $ @ @ Hashin Z., Analysis of composite materials-A Survey, ASME Journal of Applied Mechanics, 50, 481-505 (1983) @No $ @ @ Ishai O., Failure of unidirectional composites in tension, J.

In this study, marine bacterium capable of melanin production on marine broth/agar was isolated and identified as Pseudomonas sp. (closely related to guinea) on phenotypic characterization. Melanin production activity of the isolate was studied in liquid mediums such as pure marine broth and vegetable cabbage waste. In pure marine broth, melanin yield was ~5.35 mg/mL and pigment production was absent in pure vegetable waste. However in the presence of marine broth (as starter culture) melanin yield increased to ~2.79 mg/mL. This indicates melanin production may be initiated austerely by marine broth. Pigment from the bacterium was purified and characterized using UV-visible and FTIR analysis. The morphology and size of the bacterium was visualized in scanning electron microscopy (SEM) and the pigment nature was identified by SEM/EDX analysis. The results indicated that the synthesized melanin was very near to synthetic dihydroxyphenylalanine (DOPA)-melanin in all aspects and possess antioxidant activity. <#LINE#> @ @ Sajjan S., Purification and physiochemical characterization of melanin pigment from Klebsiella sp.

The analysis presents comparison for weight of tubular member sections, with the help of which, comparative study has been done between design of truss as per revised provisions of wind load calculations given in IS 875 (Part 3):1987 and designs obtained as per calculations made in SP 38(S&T):1987; Handbook for typified designs for structures with steel roof trusses. Indian Standard Code IS: 875(Part 3)-1987 includes consideration for different conditions of class of structure, topography factor, enlarged provisions of permeability conditions, Terrain, height & structure size factor and various wind zones. These provisions of wind load calculations are different from the considerations used in SP 38(S&T):1987.Because of which, there are considerable variations in design of truss. Hence comparative analysis of design of steel roof truss is needed.  <#LINE#> @ @ Togan Durmaz and Daloglu, Optimization of roof trusses under snow loads given in Turkish Codes, International conference on Engineering Structures, 28-33, (2006) @No $ @ @ Zhong, Chunguang, Jing, structure Design of HSS Roof Trusses,Ningbo International Conference and Exhibition Center,(2003) @No $ @ @ Dubey S.K., Sangamnerkar Prakash and Soni Prabhat, Design optimization of steel roof trusses, Proceedings of National Conference on Advances in steel structures, (2011) @No $ @ @ Dubey S.K., Sangamnerkar P., Soni Prabhat, Analysis of Steel Roof Trusses under Normal Permeability Condition, International Journal of Advanced Engineering Research and Studies, 1(4), 8-12 (2012) @No $ @ @ Indian Standards IS: 875(Part 1)-1987: Code of Practice for Design Loads (Other than Earthquake), Part I: Dead Loads., Part II: Live Loads, Part III: Wind Loads (1987) @No $ @ @ Indian Standards IS: 875-1964 (1964) @No $ @ @ SP38(S and T) 1987-Handbook of typified designs of structures with steel roof trusses (with or without cranes) based on IS Codes (1987) @No
