We have synthesized eco-friendly, economic, and equally efficient polysulfobetaine-based gel electrolyte to the alternative of liquid electrolyte in the fabrication of dye-sensitized solar cells (DSSCs) for the first time. This nitrogen-rich and highly conductive polysulfobetaine was synthesized by an easy and facile method without the use of any catalyst and explored for its DSSC application. The synthesized polymer gel electrolyte exhibited good ionic conductivity about 6.8 × 10-3 Scm-1 at ambient temperatures. DSSCs were fabricated based on this polysulfobetaine gel electrolyte and studied for their performance based on photovoltaic parameters. The DSSC photovoltaic results were appreciable and are Voc = 0.82 V, Jsc = 11.49 mA/cm2, FF = 66%, and PCE = 6.26% at 1 sun intensity. These values are slightly lower than conventional liquid electrolyte-based DSSC shown as Voc = 0.78 V, Jsc = 12.90 mA/cm2, FF = 69%, and PCE = 7.07%, both at 100 mWcm-2. Conductivity and photovoltaic parameters of the device reveals that as prepared polysulfobetaine-based polymer gel electrolyte may be useful in the fabrication of DSSC and other electrochemical devices. © 2017 John Wiley & Sons, Ltd.

One of the generalizations of fuzzy programming (FP) is intuitionistic fuzzy programming (IFP). IFP and goal programming (GP) are two important techniques for determining the solution (optimal) of multi-objective optimization problem by transforming it to a single objective one. The main purpose of this article is to introduce the similarities between IFP and GP. In this work, the max and min-operator are considered to transform the IFP to a deterministic program. One example is given to show the applicability of the proposed theory. © Springer Nature Singapore Pte Ltd. 2017.

In this paper, a production inventory model is designed with the assumption made about the cost function that will influence the empirical results obtained regarding measurement of volume flexibility. We consider a particular kind of products which are usually stored in stacks and damaged during the storage due to accumulated stress of heaped stock. These are known as damageable items. Here the model is developed for such items with stock-time-price sensitive demand and shortages. The unit production cost is taken to be a convex function of the production rate. The mathematical expression for the total relevant cost is derived and it is minimized subject to different constraints of the system. Because of the nonlinearity and complexity of the problem, the model is solved numerically and the final evaluations are made using genetic algorithm (GA). A numerical example is given and sensitivity analyses are performed to analyze the influence of various parameters on the overall cost. The results can help those manufacturing firms which deal in damageable products. © 2012 Springer India Pvt. Ltd.

Wheat production and productivity in the past witnessed a remarkable growth. However, this growth rate could not be sustained during the last decade, causing concern among world wheat community. Marker-assisted selection (MAS), which is being practiced for improvement of a variety of traits in wheat around the world, may at least partly help in providing the desired solution. Marker-trait associations are now known for a number of simple, but difficult-to-score traits, so that MAS has been found useful for improvement of several of these important economic traits. Breeding strategies including marker-assisted backcrossing, forward breeding, MAS involving doubled haploid technology and F2 enrichment have been successfully utilized for this purpose. However, for improvement of complex polygenic traits, newer technologies based on high throughput genotyping associated with new marker systems (e. g., DArT and SNP), and new selection strategies such as AB-QTL, mapping-as-you-go, marker-assisted recurrent selection and genome-wide selection will have to be tried in future. The progress made in all these aspects of marker-assisted wheat breeding, and the limitations and future prospects of this emerging technology have been reviewed in this article. © 2009 Springer Science+Business Media B.V.

The paper emphasizes on two warehouse manufacturing model for deteriorating items following time dependent demand pattern. Every manufacturing organization intends to produce perfect quality items. Due to long course of action, various types of difficulties concerning machinery capabilities, labor potential or facility from other resources may appear. Consequently, the systems shift from in-control state to out-of-control state which leads to the production of imperfect quality items. The produced lot can be screened at a cost and then separated defective items can be sold at reduced selling price. Using LIFO (last in first out) dispatching policy for model formulation, our objective is to determine the maximum total profit and the corresponding optimum decision variables. This problem is a constrained non-linear programming and hence a parameter-tuned Genetic Algorithm (OA) is implemented to solve it efficiently. The application of the model is illustrated by providing a numerical example and result is analyzed regarding the impact of various parameters on the proposed policy. © 2012 Published by Elsevier Ltd.

Objective: This study was undertaken to establish a cutoff significant titer for Widal test using healthy volunteers as control group. Utilizing the baseline titer obtained from the control group, a diagnosis of typhoid fever was made in the test group comprising outpatients and inpatients. Methods: Blood samples were collected from healthy volunteers and patients attending G.S Medical College and Hospital, Pilkhuwa, over a period of 6 months from September 2016 to March 2017. Antibodies to Salmonella typhi (TO, TH) and Paratyphi A (AH) and Paratyphi B (BH) are determined by this tube agglutination test. A total of 124 healthy controls and 303 patients having clinical suspicion of typhoid fever were subjected to Widal test. Results: In healthy control group, titer TO ≥20 was observed in 43 (34.7%), TO ≥40 in 48 (38.7%), TO≥80 in 25 (20.2%), and titer TO ≥160, TO ≥320 was observed in none of the control group. Titer TH ≥40 in 58 (46.8%), AH ≥40 in 7 (5.6%), and BH ≥40 in 13 (10.5%) were observed in the control group. Among the test group, 96 (31.7%) sera were positive out of 303 clinically suspected enteric fever by the Widal test. Among different age group studied, 34 (46.6%) patients belonged to the age group of 11-20 years which formed the highest followed by the age group of 21-30 years (33.3%). Conclusion: Based on the study, a cutoff titer of ≥160 for anti-O and anti-H antibodies and titer of ≥80 for anti-AH and anti-BH antibodies be considered as significant titer in diagnosis of enteric fever in this region. The baseline titer helps in early recognition and treatment of this serious health problem. © 2017 The Authors. Published by Innovare Academic Sciences Pvt Ltd.

Today, the world is taking large leaps of progress in technology. The technology is turning the vision of achieving transparency, speed, accuracy, authenticity, friendliness and security in various services and access control mechanisms, into reality. Consequently, new and newer ideas are coming forth by researchers throughout the world. Khan et al. (Chaos Solitons Fractals 35(3):519-524, 2008) proposed remote user authentication scheme with mobile device, using hash-function and fingerprint biometric. In 2012, Chen et al. pointed out forged login attack through loss of mobile device on Khan et al.'s scheme and subsequently proposed a scheme to improve on this drawback. Truong et al. (Proceedings of 26th IEEE International Conference on Advanced Information Networking and Applications, pp 678-685, 2012) demonstrated that in Chen et al.'s scheme, an adversary can successfully replay an intercepted login request. They also showed that how an adversary can make fool of both the participants of Chen et al.'s protocol by taking advantage of the fact that the user is not anonymous in scheme. Further, they proposed an improvement to Chen et al.'s scheme to cut off its problems. Through this paper, we show that Chen et al.'s scheme has some other drawbacks too and the improvement proposed by Truong et al. is still insecure and vulnerable. We also propose an improved scheme which overcomes the flaws and inherits the goodness of both the schemes, Chen et al.'s scheme and Truong et al.'s scheme. © 2013 Springer-Verlag Wien.

Increasing communication traffic and plans to increase various services may cause a serious problem towards the power consumption of network equipment. One of the causes of large power consumption in the present network is the multiplexing scheme, such as wavelength division multiplexing (WDM) and electrical routing of the packet signals. WDM requires O/E (optical to electrical) and E/O (electrical to optical) signal conversion circuits with the same number as that of wavelength, resulting in an increase in power consumption. In addition to this electrical signal processing for the IP packet, routing, and switching at the router consumes a large amount of power. If we could process ultrafast signals using electromagnetic light waves without converting to electrical signals, this would reduce the power consumption of routers. One of the ways to overcome these problems is the development of all-optical computing devices. All-optical computing devices are based on the nonlinear interaction of light waves, which is an electromagnetic wave. The use of electromagnetic light waves makes computing, such as switching, possible at very high frequencies of more than 100 GHz. We discuss all-optical computing devices based on semiconductor optical amplifiers with the main emphasis on all-optical logic gates. © 2012 Society of Photo-Optical Instrumentation Engineers (SPIE).

In this paper we discuss one parameter Lindley distribution. It is suggested that it may serve as a useful reliability model. The model properties and reliability measures are derived and studied in detail. For the estimation purposes of the parameter and other reliability characteristics maximum likelihood and Bayes approaches are used. Interval estimation and coverage probability for the parameter are obtained based on maximum likelihood estimation. Monte Carlo simulation study is conducted to compare the performance of the various estimates developed. In view of cost and time constraints, progressively Type II censored sample data are used in estimation. A real data example is given for illustration. © 2011 IMACS.

A field experiment was conducted during the winter season of 2009-10 to find out the optimum dose of phosphorus and sulphur on growth, nodulation, yield attributes and yield of garden pea (Pisum sativum L.). Four levels of P2O5 (0, 20, 40 and 60 kg/ha) and three levels of sulphur (0, 20 and 40 kg/ha), were applied through single super phosphate and gypsum, respectively. Treatments were replicated three times in factorial randomized block design. Application of phosphorus and sulphur resulted in an increase in various growth characters, nodulation, yield attributing traits and yield of garden pea. The application of 60 kg P2O5 produced the highest mature green pod yield (73.83 q/ha). Similarly the levels of sulphur up to 40 kg/ha showed linear increased in growth, nodulation and yield of garden pea. The application of 40 kg sulphur produced the highest yield of 66.51 q/ha.
