|A Frame Work for Quality Assessment Using Critical Factors of the Primary Health Care: A Case of Rural Area in North Karnataka|
India is made up of villages, Primary health care (PHC) are the backbone of these villages in health sector. PHC is not new to India. Due to lack of inadequate resources, inadequate staff and many problems PHCs of India in general and PHCs of Karnataka are in particular are suffering. An attempt is made to assess critical factors affecting the quality treatment. The main objective of this paper is to present a frame work for north karnataka rural area PHC by assessing various factors, considering critical factors using existing model and the literature of health care services for quality treatment and improvement of PHC. This would enable PHC medical officer understand how patient evaluate the quality treatment provided and aid them to allocate necessary resources, facilities, staff etc to various aspects of healthcare, considered to be important by the patients. List of general and critical factors are identified, patients give feedback on these critical factors in turn medical officers and other staff also gives the feed back on these critical factors, finally integrating and comparing critical factors the quality treatment is assessed. The current work could be extended to determine the link between various aspects of PHC and patient satisfaction.

|The Role of Project Manager in Improving the Projects Performance|
A project manager is the person who has the overall responsibility for the successful initiation, planning, design, execution, monitoring, controlling and closure of a project. And to complete the project on schedule, with in the budgeted costs and specified quality towards making the project a success. However, many reports have shown the opposite results. Studies on this issue are pointing towards the poor understanding of good practice as a basic problem for the failures in project management. The objective of this paper is to identify the competency skills that a project manager should have to influence a successful project performance. The data was collected as well as obtained from and through project reports, questionnaires and interviews with the project managers and project teams of the relevant projects. The variables were then separated into two classifications that could be defined as either success or failure. The good project management practices result in a higher project performance.

|Analysis of Banded Texture of Friction Stir Weld Bead Surface by Image Processing Technique|
The tool shoulder of friction stir welding is considered to be one of the prime element which controls the material flow and heat input, generating required temperature and hydrostatic pressure along the weld line in producing a defect-free weld. The interaction of tool shoulder with base material in the formation of friction stir weld is studied by analyzing the banded texture of weld bead surface using image processing techniques, since the textures form an important clue for the recognition of surface. Experiments are carried out by capturing the images of weld bead surface of friction stir welded specimens produced using different process parameters. The images are digitally processed and analyzed by defining suitable region of interest along good and defect weld region based on X-Ray radiography results of friction stir welded specimens to determine first order and second order statistical textural parameters of weld bead surface using MATLAB. The variation in the textural parameters along good and defect weld regions are observed which enables to assess the quality of friction stir weld using image processing.

|An Optimal Replacement Problem for Three–State Repairable Systems Using Arithmetico-Geometric Process|
This paper demonstrates a Deteriorating Simple Repairable System with three states. They include two failure states and one working state. Assuming that the up times and down times are exposing to Arithmetico Geometric Process an attempt is made to obtain replacement policy N under which we replace the system when the number failures of the system reaches N. An explicit expression of the average cost rate is derived and corresponding optimal policy N* is obtained. Finally it provides numerical results.

|Direct Reusing of Textile Wastewater in Scouring-Bleaching of Cotton Goods Devoid of Any Treatment|
Reusing of textile wastewater is generally based on some sorts of wastewater treatment process before reusing. Current paper discusses the direct reusing of textile wastewater without any treatment which not only can reduce the freshwater consumption rate but also reduce the effluent load. Six different types of rinsing wastewaters were studied. Wastewaters were segregated by collecting them separately from the drain line of dyeing machine. Then collected wastewaters were used for the scouring bleaching of knitted cotton fabric. Few specific types of rinsing water have showed bright prospect of reusing. Among them, one type of ‗before dyeing rinsing' water has found to be quite acceptable and safe to reuse for the scouring-bleaching of cotton goods. Bleached samples were then dyed to investigate the dyeing performance. Weight loss of scoured-bleached sample has found 6.65% for wastewater and 6.53 % for fresh water. Reflectance of whiteness of bleached wastewater and fresh water samples have found 76.68% and 77.92 % respectively whereas the shade variation between them was only 0.62 (ΔE value) which is quite acceptable. Absorbency of bleached samples have also found excellent. After dyeing, the variation of shade between fresh water and wastewater treated samples have found 0.65 (ΔE value) which is also well below the maximum acceptable limit. Beside this, Fastness rating of wastewater treated samples were 4/5, 4 and 4/5 for rubbing, washing and perspiration fastness respectably.

|Two-Layer Fuzzy Logic Based Load-Frequency Controller for a Two-Area Interconnected Power System Considering Nonlinearities with Super Capacitor Energy Storage Units|
This paper proposes a sophisticated application of Super Capacitor Energy Storage (SCES) unit for the improvement of the Load-Frequency Control in a two-area interconnected power system considering Governor Dead Band (GDB) and Generation Rate Constraints (GRC) nonlinearities. In this paper, the proposed fuzzy controller, called as two layered fuzzy controller, consists of two layers. The first layer is called compensator, which is used to generate and update the reference value of Area Control Error (ACE). The second layer called feedback fuzzy logic controller, makes ACE decay to zero at steady state. The proposed two layered fuzzy controller, with the updated reference value of Area Control Error using pre-compensator ensures the ACE to zero with the inclusion of Proportional plus Integral (PI) controllers. The Integral Square Error (ISE) criterion is adopted in optimizing the PI controller gains. In addition to levelling load, the SCES is advantageous for secondary control in the power system and maintains the power quality. When an AC power system is subjected to load disturbances, considerable frequency oscillations may result to system instability. So as to ensure the system stability, the power modulation control offered by SCES is enhanced to suppress the peak value of the transient frequency deviation. Simulation results show that the proposed two layered fuzzy logic controller is not only effective in damping out the frequency oscillations, but also capable of alleviating the transient frequency swing caused by large load disturbance. Moreover, the output results obtained proves that the proposed two layered fuzzy load frequency controller provides very good transient and steady state response compared to the fuzzy controller and conventional PI controllers.

|Comparison of Photoconduction Property of Pbpc and Cupc Thin Films|
A thin film of Lead Phthalocyanine (PbPc) and Copper Phthalocyanine (CuPc) on glass substrates were prepared by Vacuum deposition method for a study of photoconduction properties. The thicknesses of the films were 150 nm, 300 nm and 450 nm on glass substrate. The higher thickness 450 nm films were annealed in air at 323 K and 373 K. The Current-Voltage characteristics were measured under dark and illumination conditions at the temperature of 30˚C using a double beam spectrometer. For illuminating, light of 100 W halogen lamps was used and focused on the sample. The light intensity varied from 0 to 1 mW/cm2 and applied voltage from -30 V to 30 V. The conductivity of PbPc and CuPc on the glass substrates was studied. The electrical property of PbPc and CuPc were caused by the orientation of the molecular planes in the films, which was due to their one dimensional conductivity nature of Pb ions.

|Low-Power Video Codec Design|
Power consumption is the most critical design issue in a portable appliance. For a battery-operated mobile device to support high-complexity multimedia functions, low- power and power-aware techniques are the key to a successful design. This article reviews typical techniques for a low-power video IC design, and introduces emerging power-aware concepts toward a more power-efficient video codec. obile multimedia devices such as smart phones are energy-constrained, so reducing their power is critical for extending video playback times. The goal of this thesis is to explore different power saving techniques for video decoders and demonstrate them on a hardware application-specific integrated circuit (ASIC) architecture.
