Air quality models form one of the most important components of an urban air quality management plan. Various statistical modeling techniques (regression, multiple regression and time series analysis) have been used to predict air pollution concentrations in the urban environment. These models calculate pollution concentrations due to observed traffic, meteorological and pollution data after an appropriate relationship has been obtained empirically between these parameters. In the present paper, a review of the applications of ANN in vehicular pollution modeling under urban condition and basic features of ANN and modeling philosophy, including performance evaluation criteria for ANN based vehicular emission models have been described.

P S Chakraborty , G Majumder & B Sarkar

This study, done on a light engineering industry situated at Faridabad having most of the vendors within 10 K.M radius, evaluates the performance of existing die casting vendors. The organization wants to reduce existing die casting vendors from five to three. System adaptability criterion consists of factors such as green manufacturing, support to lean manufacturing by adapting Direct on Line (DOL) system. Other criteria are cost, quality, schedule adherence and general cooperation Performance of the vendors was evaluated using Analytical Hierarchy Process (AHP), which is a powerful and flexible decision-making tool for complex, multi-criteria problems. Consistency ratio was checked. Composite rank was calculated for vendors. Based on composite rank score recommendations were made. After that number of vendors reduced to streamline the supply chain.

Design of adaptive neuro-fuzzy inference system for predicting surface roughness in turning operation

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Shibendu Shekhar Roy

This paper proposes an Adaptive Neuro-Fuzzy Inference System (ANFIS) for predicting the surface roughness in turning operation for set of given cutting parameters, namely cutting speed, feed rate and depth of cut. Two different membership functions, triangular and bell shaped, were adopted during the training process of ANFIS in order to compare the prediction accuracy of surface roughness by the two membership functions. The comparison of ANFIS values with experimental data indicates that the adoption of both triangular and bell shaped membership functions in proposed system achieved satisfactory accuracy. The bell-shaped membership function in ANFIS achieves slightly higher prediction accuracy than triangular membership function.

This paper presents brief account on smart antenna (SA) system. Smart or adaptive antenna arrays consist of an array of antenna elements with signal processing capability, that optimize the radiation and reception of a desired signal, dynamically. SAs can place nulls in the direction of interferers via adaptive updating of weights linked to each antenna element. SAs thus cancel out most of the co-channel interference resulting in better quality of reception and lower dropped calls. SAs can also track the user within a cell via direction of arrival algorithms.

Estimation of uncertainty in measurement in precision calibration of DC high current source up to 100 A

 

 

 

 

 

 

 

Shiv Kumar Jaiswal, V N Ojha &
Ajeet Singh

 

In the present paper, calibration of precision DC high current source (> 2 A and up to 100 A), widely used in industries and research, has been discussed as case studies of transconductance amplifier and precision power supply calibration. The various sources of uncertainty in measurement and their estimation based on Type A and Type B method as per ISO ‘GUM’ document are discussed in detail. The results are reported at coverage factor k=2 for approx 95% confidence level. The standards used for calibration are traceable to the ‘National Standards’ and their uncertainties were evaluated prior to use to avoid variation in results due to drift.

Navin Chandra, Nitin Agnihotri, Priya Sharma, Sanjeev Bhasin & S S Amritphale

 

Separation of lead ions from aqueous solutions containing 5, 10, 20, 50, 100, 200 and 500 ppm lead was studied by adsorption at the surface of talc mineral of Indian origin. The effect of temperature (20, 30, 40, 50, 60, 70oC) on adsorption phenomena was studied and the data was analyzed using Langmuir isotherm. The changes in enthalpy (DH), free energy (DG) and entropy (DS) were evaluated. The negative values of DG and DH indicate the adsorption of lead ions on talc surface to be spontaneous and exothermic under the experimental conditions.

Effect of titanate coupling agent on clay and talc has been studied with polybutadiene as a matrix. Tensile properties were measured on a computerized UTM using ASTM procedure. Comparison of properties of composites filled with treated and untreated fillers established that treatment of fillers imparts better reinforcing properties. The properties under consideration were tensile strength, modulus (100% & 400%), Young’s modulus, hardness, etc. Improvement in properties for clay and talc respectively were as follows: Tensile strength, 14, 19; Modulus (400%), 140, 90%; and Young’s modulus, 275, 25%.

Study on sodium and potassium salts of polyacrylic acid as corrosion inhibitors

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

S Mishra, I D Patil & Dipak Deore

The effect of sodium and potassium (20-100 ppm) salts of polyacrylic acid (PAA) was determined on mild steel (MS) and copper (Cu) metals by immersing in Jalgaon ground water for 4-24 h in reflux condition (100 °C) and from 5-30 days in ambient condition. The salt deposition on MS and Cu increases with increase in time in hot and cold water without addition of polymer. On addition of polymer, with increase in concentration in water, the salt deposition decreases. In cold water on MS, salt deposition is more than Cu, while in hot water it is vice-versa. With increase in the reflux time (4-24 h), salt deposition on Cu and MS increases up to 6 h of reflux time for all concentrations of K salt of PAA and further it decreases from 12 to 24 h. For Na salt of PAA, deposition increases for the lower concentrations (up to 40 ppm), up to 12 h of reflux time and further the deposition decreases for both MS and Cu. At higher concentrations (100 ppm), Na salt of PAA in water is more effective than K salt as the deposition becomes negligible on Cu.

Production and partial characterization of alkali-tolerant xylanase from an alkalophilic Streptomyces sp. CD3

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Pankaj Sharma & Bijender K Bajaj

Of the 30 isolates screened, Streptomyces sp CD3, an alkalophilic isolate, showed maximum xylanase production. Organism efficiently used wheat bran and bagasse as substrates and produced 2.211 and 1.896 U/ml of xylanase, respectively. Soybean meal supplementation enhanced xylanase production substantially, while yeast extract and gelatin did so moderately. Although, optimum enzyme activity was at pH 8 and temperature (50oC), but enzyme retained considerable activity at higher pH (80% at 9-10) and temperature (60 % at 70-90oC). The enzyme was strongly inhibited by Hg2+, while Fe3+, Ca2+ and Zn2+ were slight inducers of xylanase. Zymogram analysis suggested the presence of three xylanases (mol wt, 69.18, 63.09 & 43.65 kDa). Purification (108-fold) was achieved by carboxymethyl sephadex chromatography. Enzyme obeyed Michaelis-Menten kinetics (Km 3.9 mg/ml). Industrially desirable characteristics of the enzyme like thermostability and alkali-stability, and highly alkalophilic nature of the organism, and its ability to grow and produce enzyme on low value agricultural by-products reflects the potential commercial importance of this study.

Experimental analysis of heat pipe solar collector with different L/dI ratio of heat pipe

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

B Sivaraman & N Krishna Mohan

Heat Pipe Solar Collector has better collecting efficiency compared to the conventional collectors. In this paper, experiments on the effect of L/d ratio of heat pipe on heat pipe solar collector are presented. Heat pipes are designed to have heat transport factor of around 194 W and 260 W of thermal energy. Experiments were conducted during summer season with a collector tilt angle of 13o to the horizontal. The collector with L/di ratio of 52.63 was found to be more efficient than the collector with L/di ratio of 58.82. This improved efficiency is due to increase in heat transport factor of heat pipe, which increase with decrease in L/di ratio.

Raj Kumar Agrawal & Piyush Kant Pandey

The study describes techniques of recycling the gas cleaning plant (GCP) sludge generated during basic oxygen furnace (BOF) steel making process. Two different experiments were conducted to gainfully utilize converter sludge in iron making and steel making. The experiments resulted in two different products namely lime sludge briquette (LSB) and dolomite sludge mix (DSM). While LSB is used as a coolant in steel making, DSM is used for sinter production. Each one is having cost effective advantages on one hand and substantially reduced dumping of waste on the other.
