Background/Objectives: When conventional PI controllers are used to control non linear processes, the controllers must be tuned very conservatively in order to provide stable behavior over the range of operating conditions. The conservative controller tuning can result in serious degradation of control system performance. Therefore it is necessary to go for optimizing techniques. Methods/Statistical Analysis: In this paper a modified approach of firefly algorithm is compared with the firefly algorithm. The modified approach is derived from the impact of the tuning parameters over the objective function peak overshoot. This modified approach using firefly algorithm is validated through simulation results. The transfer functions employed here are stable second order system, second order with inverse response and higher order systems, particularly non minimum phase systems. Findings: For the stable second order systems and for the higher order non minimum phase systems the modified approach based on firefly algorithm outperforms the existing firefly algorithm. The modified approach not only reduces the considered objective functions such as PO, ITAE but also the other functions such as ITAE and settling time. Application/Improvements: The modified approach can also be extended for unstable systems. The modified approach is discussed with third order systems here. However it can be extended for still higher order systems.Keywords

Impulse buying is an emerging phenomenon, which has been the focus of the retailers to attract the customers. Impulse behaviour is the outcome of emotional reactions that generate unpredicted urge to buy. An extensive review of literature on impulse buying has been done in this paper. Several researches on impulse buying have been conducted in many countries. The study’s contribution to the literature is to identify the potential role of impulse buying in consumers purchase decision.

This research work focuses on the cyber crime for the illegal activities which is potentially large. To save the information the Laser Pumer technology is used. By using this involves the scanning process more than one for various eye patterns and fingerprint, permission can be given for access after recognition and restrict the access from intruders. The sensor device reads the fingerprints at any angle and it does not require power supply. The USB Port capability makes it truly plug-and-play and makes an easy access.Keywords

Duloxetine is chemically N – methyl-3-(1-naphthyloxy)-3-(thiophen-2-yl)-propan-1-amine, is a balanced and potent reuptake inhibitor of serotonin and norepinephrine. Methylcobalamin is chemically Methyl-5, 6-dimethyl benzimidazolylcobalamin, is one of the two coenzyme forms of vitamin B12 in the enzyme methionine synthase which functions to transfer methyl groups for the regeneration of methionine from homocysteine. The combination of these two drugs is used in relieving the complications of diabetic peripheral neuropathy. The aim of the current study is to develop a modified simultaneous spectrophotometric determination (Q-Absorbance ratio method) of duloxetine and methylcobalaminin bulk and pharmaceutical dosage form (tablet and capsule). Duloxetine has exhibited maximum absorbance at 288 nm and it transparent at 326 nm. The isobestic point was selected at 254 nm as both the drugs recorded maximum absorbance, also it was found wavelength difference is higher when compared to 278 nm. In replicate analysis (n=5) of the two drugs by the proposed UV method, the % label claim and % RSD of duloxetine and methylcobalamin were appreciably low for tablet and capsule formulation. The correlation between absorbance and concentration in terms of correlation coefficient (r) was found to be 0.9956 and 0.9979. The validation parameters observed proved that this method simple, sensitive, accurate and precise. Hence, the developed new method can be employed for the routine analysis of these two drugs in combined dosage forms.Keywords

A graphical password system is based on cued click point. In this scheme contains a cued-recall graphical password technique. Users Click on one pixel per image for a sequence of images. The second image is based on the previous pixel. Compared with other graphical password methods performance and accuracy was very good in terms of speed. Users preferred pixel point to passed click Points. It is easy to remembering only one pixel for one image. Here each picture triggered their memory of where the corresponding pixel was located. Cued Click Point also provides higher security than Pass Points because it increases the workload for attackers.Keywords

The SGML is not supporting in web browsers, to avoid this problem SGML content is converted into HTML. The biggest barrier is reuse, interchange and automation. Several computers are having the in unsupported formats. That is the case exchanging data between the two systems is the longest process for web developers. Most of the time a very wide amount of data must be lost due to unsupported file format. The XML is the highly efficient derived from SGML. The main goal of XML is to specifying SGML elements are supported in web browsers then it is easy to publish SGML content on the web.Keywords

A study was conducted to assess the impact of different nutrient management practices on soil quality in a permanent manurial experiment cotton field established in 1982 at the Agriculture Research Station of the Tamil Nadu Agricultural University, which falls under the dryland ecosystem of Kovilpatti in Tamil Nadu, India. The experiment was carried out in a randomized block design with nine different treatments. The effect of these treatments in different depths (0–15, 15–30 and 30–45 cm) was compared, and the soil quality index was developed with a total of 27 parameters, including physical, chemical and biological parameters. Principal component analysis was carried out and the principal components with eigenvalue >1 were selected to determine the indicators to be retained in the minimum dataset. The highly weighted variables, viz. field capacity, available water content, cation exchange capacity, nitrogen, phosphorus, potassium, calcium, magnesium, etc. with a variance of 93.57% were retained for MDS. Linear scoring functions were used to transform them into unitless scores ranging from 0 to 1. Three different methods of soil quality were analysed, viz. weighed additive soil quality index (SQIw), additive soil quality index (SQIa) and Nemoro soil quality index (SQIn). In all three methods, the treatment receiving farmyard manure at 12.5 t ha–1 showed superiority in maintaining soil qualityKeywords
