An ensemble lossless watermarking scheme is proposed in the present study by integrating different concepts like redistributed invariant wavelet transform, discrete fractional Fourier transform, singular value decomposition (SVD) and visual cryptography within the framework of a single algorithm. The invariant wavelet transform helps to obtain the transform domain, which is invariant to flipping and rotation of image, this is followed by discrete fractional Fourier transform to obtain the translation invariant domain. Finally, embedding positions are selected based on a key and reliable features are extracted by performing SVD on a window centered at these positions. Based on these reliable features a binary map is generated through which a master share is created. The corresponding ownership share is produced from the master share and the watermark. In verification process the same operations of the embedding process are applied to the test image to obtain the master share and the watermark is recovered by stacking it over the ownership share. There are two main features of the proposed scheme (1) The quality of the image to be watermarked do not degrade during the process and (2) the extracted watermark can still be identified even from a seriously distorted image. These findings are also demonstrated with the help of a comparative study with several related schemes. © 2017 Springer Science+Business Media New York

Sufficient literature is available on approaches to deal with heterogeneous traffic on mid-blocks in developing countries, but not much work is done on roundabouts. The estimation of passenger car unit (PCU) for different vehicles to convert heterogeneous traffic into homogeneous traffic is a well-accepted procedure. But the parameters used for mid-blocks may not be helpful on roundabouts as traffic flow characteristics on the two locations are different. Suggested PCU values on roundabouts from developing countries are not recent, and needs a relook. It is also not clear whether to use static or dynamic PCU values on account of possible temporal and spatial variations across locations. This paper presents an estimation approach for PCUs on roundabouts and suggests using static value instead of dynamic. The problem to deal with re-estimation of PCU values at different locations, due to possible traffic flow variations, is dealt with by proposing a heterogeneity equivalency factor (H-Factor). The factor is multiplicative and converts heterogeneous traffic (veh/h) into homogeneous traffic (pcu/h). © 2017, Iran University of Science and Technology.

Managing service quality has always been one of the most important areas of concern in hospitals. With the advancement of lifestyle, education and awareness among consumers, they are becoming more and more demanding. This is the reason why hospitals are spending huge amount in managing service quality that leads to satisfaction among patients and ultimately contributes in brand building. Thus the first and most important consideration is to determine and understand the various dimensions of service quality in the perspective of hospitals. Many researchers have studied these dimensions of hospital service quality but none of the studies cover all the possible areas of service quality management in a hospital set-up. This study aims to critically review the work of different researchers to determine and define the dimensions that would cover all areas of service quality management in hospitals. This study has developed a conceptual framework of hospital service quality by identifying 15 different dimensions: infrastructure, resource availability, waiting time, food, clinical procedures, administrative procedures, price, trustworthiness, information availability, patient safety, continuity, personalized attention, staff attitude, quality of outcome and religious needs. These 15 dimensions are further clubbed under three broad dimensions such as ‘infrastructural dimension’, ‘procedural dimension’ and ‘interactional dimension’. These dimensions can be used for measuring service quality management practices followed across different categories of hospitals like public and private or multi-specialty and super-specialty. © 2017 Indian Institute of Health Management Research.

Multivariate analysis is a type of multivariate statistical approach commonly used in, automotive diagnosis, education evaluating clusters in finance etc and more recently in the health-related professions. The objective of the paper is to provide a detailed exploratory discussion about factor analysis (FA) in image retrieval method and correlation analysis (CA) of network traffic. Image retrieval methods aim to retrieve relevant images from a collected database, based on their content. The problem is made more difficult due to the high dimension of the variable space in which the images are represented. Multivariate correlation analysis proposes an anomaly detection and analysis method based on the correlation coefficient matrix. Anomaly behaviors in the network include the various attacks on the network like DDOs attacks and network scanning. © 2014 AIP Publishing LLC.

Glycation is the result of covalent bonding of a free amino group of biological macromolecules with a reducing sugar, which results in the formation of a Schiff base that undergoes rearrangement, dehydration and cyclization to form a more stable Amadori product. The final products of nonenzymatic glycation of biomacromolecules like DNA, proteins and lipids are known as advanced glycation end products (AGEs). AGEs may be generated rapidly or over long times stimulated by distinct triggering mechanisms, thereby accounting for their roles in multiple settings and disease states. Both Schiff base and Amadori glycation products generate free radicals resulting in decline of antioxidant defense mechanisms and can damage cellular organelles and enzymes. This critical review primarily focuses on the mechanistic insight of glycation and the most probable route for the formation of glycation products and their therapeutic interventions. Furthermore, the prevention of glycation reaction using therapeutic drugs such as metformin, pyridoxamine and aminoguanidine (AG) are discussed with special emphasis on the novel concept of the bioconjugation of these drugs like, AG with gold nanoparticles (GNPs). At or above 10 mM concentration, AG is found to be toxic and therefore has serious health concerns, and the study warrants doing this novel bioconjugation of AG with GNPs. This approach might increase the efficacy of the AG at a reduced concentration with low or no toxicity. Using the concept of synthesis of GNPs with abovementioned drugs, it is assumed that toxicity of various drugs which are used at high doses can be minimized more effectively. © The Author 2014.

The traditional system on chip designs employ the shared bus architecture for data transfer in highly integrated Multiprocessor system on chips(MPSoC).Network on chip (NoC)is a new paradigm for on chip communication for Multiprocessor systems on chips(MPSoCs). NoCs replace the traditional shared buses system with routing switches. Heart of the NoC is the router and it consists of an input buffer, arbiter, crossbar and an output port. The NoC router uses a buffer to store the incoming packets. These buffers improve the performance but they consume more power and area. Bufferless deflection routing is the solution for improvement in energy efficiency. In this method deflections of the packets take place to overcome the contention problem. But at high network load, deflection routing degrades the performance because of unnecessary hopping of data packets. The MinBD (minimally buffered deflection) router is a new router design that uses a small buffer for bufferless deflection routing. In this paper the input block of MinBD router is implemented on FPGA which shows that a small buffer will help to reduce the network deflection rate. It also improves the performance and energy efficiency while buffering only deflected data packets.

Indian agriculture sector heavily depends on monsoon rainfall for successful harvesting. In the past, prediction of rainfall was mainly performed using regression models, which provide reasonable accuracy in the modelling and forecasting of complex physical systems. Recently, Artificial Neural Networks (ANNs) have been proposed as efficient tools for modelling and forecasting. A feed-forward multi-layer perceptron type of ANN architecture trained using the popular back-propagation algorithm was employed in this study. Other techniques investigated for modeling monthly monsoon rainfall include linear and non-linear regression models for comparison purposes. The data employed in this study include monthly rainfall and monthly average of the daily maximum temperature in the North Central region in India. Specifically, four regression models and two ANN model's were developed. The performance of various models was evaluated using a wide variety of standard statistical parameters and scatter plots. The results obtained in this study for forecasting monsoon rainfalls using ANNs have been encouraging. India's economy and agricultural activities can be effectively managed with the help of the availability of the accurate monsoon rainfall forecasts. © 2014 AIP Publishing LLC.

This article shows experimental investigation carried out to study the effect of exposure to elevated temperature on concrete. Four concrete mixes obtained using different proportions of ground granulated blast furnace slag (GGBFS) and silica fume (SF) with 43 grade ordinary Portland cement were considered. Concrete cubes of 100 mm size were cast, cured and exposed to different peak temperatures (up to 700 °C) for different heating periods (1, 2, 3 and 7 h) and tested to failure under compression. Before subjecting the heated specimens to compression test, the heated cubes were closely examined for any signs of cracking, disintegration and loss of mass. The concrete specimens with 5% SF do not show any sign of cracks at different peak temperatures, whereas 10% SF cubes split from corners at 425 °C. However, the concrete cubes with 10% GGBFS did not show any sign of cracking even for 7-h exposure to a temperature of up to 500 °C. The mass loss of all concrete specimens increased sharply up to 200 °C, and after that, it increased marginally. The compressive strength of all concrete mixes increased up to 200 °C and decreased with further increase in temperature, with the exception of concrete containing 5% SF which increased even at higher temperatures but at a slower rate. © 2015 Taylor & Francis
