  • Full Article
To sustain today‟s highly competitive market, every company must minimize its operating expenses. Total Productive Maintenance (TPM) can play an effective role in this aspect. The main purpose of this study is to find out a proper planning system for implementing TPM at the initial stage in the organization. This study discusses the important key performance indicators or KPIs of TPM, which are Machine Breakdown time, Mean Time between Failure (MTBF),Mean Time to Repair (MTTR) and Breakdown time percentage of available time. The case study of TPM implementation has taken from a manufacturing company in Bangladesh that has started implementing TPM since January 2011. Significant improvements of these KPIs are contrasted with previous year‟s values. This study explains how TPM transforms an industry‟s overall maintenance system to increase the productivity.

A Review of Trends in Research on Web Accessibility:
  • Abstract
  • Keywords

  • Full Article
In recent years the growth of the World Wide Web exceeded all expectations.The World Wide Web is a fertile area for data mining research.Web mining is a research topic which combines two of the activated research areas: Data Mining and World Wide Web. Web mining research relates to several research communities such as Database, information Retrieval and Artificial intelligence, visualization. Automated analyses of WCAG 2.0 Level,a success criteria found high percentages of violations overall. Unlike more circumscribed studies, however, the sites exhibited improvements over the years on a number of accessibility indicators, with government sites being less likely than top sites to have accessibility violations. Examination of the causes of success and failure suggests that improving accessibility may be due, in part, to changes in website technologies and coding practices rather than a focus on accessibility per se. This paper reviews the research and application issues in web Accessibility besides proving an overall view of Web mining.

Evalutation of Reservior Impacts on Soil Quality Using Remote Sensing and Gis: A Model Study
  • Abstract

  • Full Article
The problem of soil quality in and around reservoirs is attracting attention for the last couple of years due to the unscientific and unplanned irrigation practices that are bringing a myriad problem. Modern industrialization practices such as chemical industries and indiscriminate use of fertilizers in agricultural activity containing toxic substances contribute to the environmental degradation. Such anthropogenic activities invariably result in the depletion of soil quality, Deterioration of soil quality, contamination of drinking water and various health hazards. Hence there is need to study in a comprehensive way about the soil quality issues in the catchment area. The present study is an attempt made to analyze the physico-chemical parameters and to generate the Soil Quality Index in and around the tandava Reservoir. The soil samples collected at the predetermined locations are analyzed for physico-chemical parameters for the generation of attribute database. Based on the analysis results spatial distribution maps of selected soil quality parameters namely Bulk Density, Moisture content, Organic matter, C%, pH, EC, Ca, Mg, SO4, Nitrate, Phosphorus, Potassium and Texture are prepared using curve-fitting method in GIS software. The physico-chemical analysis properties and computation of SQI are helpful in the grouping of soil samples into excellent, good, poor, very poor and unfit. The spatial distribution of SQI generated in the current study will be of much use for the planners in the management and monitoring of land resources.

An Experimental Study of Effects of Superplasticizer on Fresh and Hardened Properties of Concrete
  • Abstract

  • Reference
  • Full Article
This paper presents the results of an experimental research on the workability and compressive strength of ordinary and standard concrete. Superplasticizers are commonly known as High Range Water Reducers (HRWRs) because it permits low water cement ratio as well as the workability also affected. In this paper the properties of concrete mixtures with three different dosages of superplasticizers SNF have been investigated. In this experimental programme superplasticizer Sikament®170(SWP) of basically modified naphthalene/melamine formaldehyde sulphonate dispersion and having brown liquid confirming to IS: 9103-1999 & IS: 2645, ASTM C 494/C494M, Type F has been used. The properties investigated are workability on the fresh state and compressive strength on the hardened state of concrete by using three mixes with three superplasticizer dosages (0.2%, 0.4% and 0.6%) is used. Various concrete mixes (M-20, M-30 and M-40) are design by IS 10262:2009, Concrete Mix Proportioning - Guidelines. Compressive strength at 7 and 28 days was also determined. The graphs between different percentage of superplasticizers with W/C ratio and compressive strength are plotted. Overall 72 specimens (concrete cube) with the dimension of 150 mm x 150 mm x 150 mm were fabricated at laboratory.

This paper deals with a Cuk dc–dc converter as a single-stage power-factor-correction converter for a permanent magnet (PM) brushless dc motor (PMBLDCM) fed through a diode bridge rectifier from a single-phase ac mains. A three-phase voltage-source inverter is used as an electronic commutator to operate the PMBLDCM driving an air-conditioner compressor. The speed of the compressor is controlled to achieve optimum air-conditioning using a concept of the voltage control at dc link proportional to the desired speed of the PMBLDCM. The stator currents of the PMBLDCM during step change in the reference PMBLDCM drive (PMBLDCMD) without PFC. speed are controlled within the specified limits by an addition of a rate limiter in the reference dc link voltage. The proposed induction motor-based Air-Con system operating in ―on/off‖ PMBLDCM drive (PMBLDCMD) is designed and modeled, and control mode. Its performance is evaluated in Matlab Simulink environment. A PMBLDCM has the developed torque proportional to its Simulated results are presented to demonstrate an improved phase current and its back electromotive force (EMF), which power quality at ac mains of the PMBLDCMD system in a wide is proportional to the speed [1]–[4]. Therefore, a constant range of speed and input ac voltage. Test results of a developed controller are also presented to validate the design and model of current in its stator windings with variable voltage across it's the drive.

A Novel AC–DC Step-Up Converter For Energy Harvesting
  • Abstract
  • Keywords
  • Reference
  • Full Article
The conventional two-stage power converters with bridge rectifiers are inefficient and may not be practical for the low-voltage microgenerators. This paper presents an efficient ac-to-dc power converter that avoids the bridge rectification and directly converts the low ac input voltage to the required high dc output voltage at a higher efficiency. The proposed converter consists of a boost converter in parallel with a buck–boost converter, which are operated in the positive half cycle and negative half cycle, respectively. Detailed analysis of the converter is carried out to obtain relations between the power, circuit parameters, and duty cycle of the converter. Based on the analysis, control schemes are proposed to operate the converter. Design guidelines are presented for selecting the converter component and control parameters. A self-starting circuit is proposed for independent operation of the converter. Detailed loss calculation of the converter is carried out. Simulation results are presented to validate the proposed converter topology and control schemes.
