Speed Regulation of DC Drive Using Mobile Communication
Shakti Bajaj,Ravinder Kumar Bhataia,J.Sandeep Soni
International Journal of Soft Computing & Engineering , 2013,
Abstract: The importance of the speed control of DC motors inmanufacturing industries like plastic, textile, chemical andpharmaceutical hardly needs any emphasis as it ensures efficientand consistent production. In this paper, the authors presentimplementation of a hardware circuit which is designed forremote speed control of a DC motor by using Dual Tone MultiFrequency (DTMF) tone of mobile phone. The hardware circuitincludes the use of DTMF decoder IC MT8870 and Relay driverIC ULN2003. The mobile keypad keys have been mapped to thespeeds of ‘High Speed’, ‘Medium Speed’, ‘Low Speed’ and ‘Stop’to regulate the speed of DC motor.

Abstract: Some new construction methods of the optimum chemical balance weighing designs and pairwise efficiency and variance balanced designs are proposed, which are based on the incidence matrices of the known symmetric balanced incomplete block designs. Also the conditions under which the constructed chemical balance weighing designs become A-optimal are also been given.

Web Testing: Tool, Challenges and Methods
Shakti Kundu
International Journal of Computer Science Issues , 2012,
Abstract: Web testing is the name given to software testing that focuses on web applications. Issues such as the security of the web application, the basic functionality of the site, its accessibility to handicapped users and fully able users, as well as readiness for expected traffic and number of users and the ability to survive a massive spike in user traffic, both of which are related to load testing. In this paper web testing based on tool, challenges and methods have been discussed which will help in handling some challenges during the website development. This paper presents best methods for testing a web application.
AN INTELLIGENT APPROACH OF WEB DATA MINING
Shakti Kundu
International Journal on Computer Science and Engineering , 2012,
Abstract: With an explosive growth of the World Wide Web, websites are playing an important role in providing an information and knowledge to the end users. Web usage patterns are an important aspect to discover hidden and meaningful information. It will be big challenge in web mining when the volume of traffic is large and the volume of web data is still in the growing phase. To face the challenge an intelligent approach of web traffic analysis has been highlighted in this paper.
Simulating the Effect of Social Network Structure on Workflow Efficiency Performance  [PDF]
Akhilesh Bajaj, Sandip Sen
Social Networking (SN) , 2014, DOI: 10.4236/sn.2014.31004
Abstract:

The effect of social network structure on team performance is difficult to investigate using standard field observational studies. This is because social network structure is an endogeneous variable, in that prior team performance can influence the values of structural measures such as centrality and connectedness. In this work we propose a novel simulation model based on agent-based modeling that allows social network structure to be treated as an exogeneous variable but still be allowed to evolve over time. The simulation model consists of experiments with multiple runs in each experiment. The social network amongst the agents is allowed to evolve between runs based on past performance. However, within each run, the social network is treated as an exogenous variable where it directly affects workflow performance. The simulation model we describe has several inputs and parameters that increase its validity, including a realistic workflow management depiction and real-world cognitive strategies by the agents.

Thermostable alkaline protease production from Bacillus pumilus D-6 by using agro-residues as substrates  [PDF]
Bijender Kumar Bajaj, Gaytri Jamwal
Advances in Enzyme Research (AER) , 2013, DOI: 10.4236/aer.2013.12003
Abstract: Proteases due to their wide range of applications in biotechnological processes have been the  focus of intense research for many decades. However, from industrial application view point most of the available proteases lack desired properties; therefore, search for better and efficient thermostable alkaline proteases are always on. Bacillus pumilus D-6, isolated from dairy plant soil sample, in the current study produced protease which showed activity and stability at high alkaline pH (8 - 12) and high temperatures (70C- 100C). Enzyme activity remained unfazed even in presence of inhibitors like Pb2+and Hg2+which are considered universal inhibitors of enzyme activity. Besides, the organism successfully utilized crude agriculture based substrates as carbon and nitrogen source and produced substantial enzyme titre.



Exhaled Breath Condensates as a Source for Biomarkers for Characterization of Inflammatory Lung Diseases  [PDF]
Puneet Bajaj, Faoud T. Ishmael
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2013, DOI: 10.4236/jasmi.2013.31004
Abstract:

Inflammatory lung diseases such as asthma and chronic obstructive pulmonary disease are common and difficult to diagnose and characterize. This is due in large part to difficulty in obtaining samples directly from the inflamed lung. The collection of lung secretions by traditional methods including bronchoalveolar lavage and induced sputum collection are limited by their invasive nature. Exhaled breath condensate (EBC) is a simple and non-invasive technique of collecting fluid samples, which are representative of airway lining fluid. Advances in collection methods and evolving molecular techniques have led to development of more sensitive assays for existing biomarkers and identification of new biomarkers, which can be potentially useful in monitoring lung inflammation. In this review, we present the current understanding of various biomarkers including small molecules (H2O2, pH and nitric oxide related biomarkers), lipid mediators (8-isprostane, leukotrienes and prostaglandins), small proteins (cytokines and chemokines) and nucleic acids (DNA and microRNAs). We also discuss the differential profile of biomarkers in recognizing different patterns of lung inflammation. As the sensitivity of methods of EBC improves, this biofluid will play an increasing role in diagnosis and monitoring of lung diseases.

Synthesis and antiulcer activity evaluation of conjugates of amino acids with N-aroyl- N, N'-dicyclohexyl urea
Bharat Subudhi, Shakti Sahoo
Chemistry Central Journal , 2011, DOI: 10.1186/1752-153x-5-86
Abstract: Intraduodenal administration of mixed amino acid solution has been reported to significantly inhibit gastric acid secretion and gastrin release, stimulated by intragastric perfusion of peptone [1]. However studies conducted with individual amino acids have yielded varying results. Amino acids such as leucine, isoleucine and proline augment the acid release [2,3], where as amino acids including L-serine [4], L-tryptophan, L-arginine, glycine [5,6], tyrosine- and L-glutamic acid [7] have been shown to provide protection against gastric ulcers. Conjugate of methionine with penta-O-acetylglycyrrhizic acid healed both acute and chronic ulcers of rat stomach mucous lining and had low toxicity [8]. Esters of glycine, valine, leucine, proline and tryptophan with labdane diterpene imbricatolic acid exhibited strong gastro-protective action [9]. Although the mechanism of antiulcer action of individual amino acids is not clear, their N-acylated derivatives have been shown to have direct in vitro H+/K+ ATPase inhibitory activity as well as in vivo efficacy in pylorus ligation model [10]. Further radicals are the major causative factor in stress induced gastric ulceration [11] and antioxidants provide effective gastro protection against stress induced ulceration [12].With this background and keeping in view the good antioxidant activity of N-aroyl- N, N'-dicyclohexyl urea analogs [13], studies were undertaken to synthesize their amino acid conjugates and evaluate their in vivo antiulcer efficacy against pylorus ligation model.The N-cyclohexyl-N-(cyclohexylcarbamoyl) benzamide (1) was prepared by reacting N, N'-dicyclohexylcarbodiimide (DCC) with benzoic acid in the reported manner [13]. Equimolar quantity of benzoic acid and DCC were used with triethylamine (TEA) as catalyst. Reaction of dry toluene in presence of TEA generated the carboxylate anion that acted as nucleophile to undergo nucleophillic addition with DCC to give the O-aryl intermediate that upon rearrangement yielde
