Deep multimodal biometric recognition using contourlet derivative weighted rank fusion with human face, fingerprint and iris images

The goal of multimodal biometric recognition system is to make a decision by identifying their physiological behavioural traits. Nevertheless, the decision-making process by biometric recognition system can be extremely complex due to high dimension unimodal features in temporal domain. This paper explains a deep multimodal biometric system for human recognition using three traits, face, fingerprint and iris. With the objective of reducing the feature vector dimension in the temporal domain, first pre-processing is performed using Contourlet Transform Model. Next, Local Derivative Ternary Pattern model is applied to the pre-processed features where the feature discrimination power is improved by obtaining the coefficients that has maximum variation across pre-processed multimodality features, therefore improving recognition accuracy. Weighted Rank Level Fusion is applied to the extracted multimodal features, that efficiently combine the biometric matching scores from several modalities (i.e. face, fingerprint and iris). Finally, a deep learning framework is presented for improving the recognition rate of the multimodal biometric system in temporal domain. The results of the proposed multimodal biometric recognition framework were compared with other multimodal methods. Out of these comparisons, the multimodal face, fingerprint and iris fusion offers significant improvements in the recognition rate of the suggested multimodal biometric system

Awareness of lifestyle modification in females diagnosed with polycystic ovarian syndrome in India: explorative study

Background: Polycystic ovarian syndrome (PCOS) adversely affect women at varying stages of their life and imperative to emphasis on prevention strategies since incidence of PCOS is on the rise. Study aims to explore perception on PCOS, awareness on life style modification, emotional attributes, concern regarding PCOS and utilization of physiotherapy services.Methods: The study was conducted in Mumbai and Navi Mumbai, India. Self-made validated questionnaire was administered. Descriptive analysis was done. Perception on PCOS, lifestyle modification, emotional attribution and biggest concern were calculated as absolute frequencies and were reported as overall percentages. Chi square test was applied on the demographic factor’s influence on level of awareness.Results: 21% of the respondents are very well aware about PCOS. 51% reported as doctor was their main source of information about PCOS. 81% expressed that PCOS is manageable one. 62% aware that exercise helps in the management of PCOS. Out of this, 39% are doing exercise on a regular basis. However all the study participants reported, they have not had any consultation from physiotherapist for their structured exercise program.32% attributed to anxiety after the diagnosis of PCOS. 64% of the respondents aware that changing in diet or eating habits can influence in PCOS. However 95% of the subjects concurred to follow life style modification.Conclusions: Efforts need to intensify in creating awareness on the general public about PCOS. Absolute majority of the study participant uncoerced to follow lifestyle modification however emphasis needs to address on multidisciplinary approach in managing PCOS

A SINGLE AND BATCH SERVICE QUEUEING SYSTEM WITH ADDITIONAL SERVICE STATION

ABSTRACT A single and batch service queueing system with two servers is considered in this paper. The arrival process is assumed to be Poisson with parameter λ and the service rule is as follows: when the number of customers is less than or equal to c, then server-I takes a customer one by one for service according to First Come First Served (FCFS) basis and mean service rate follows an exponential distribution with parameter 1 µ and if the number of customers is more than c and less than d then server-I serves the customers altogether in a batch and mean service rate follows an exponential distribution with parameter 2 µ and if the number of customers is more than d then server II is activated and both servers are busy with batch service, where server-I serves (d-1) customers in a batch and the remaining customers are served by server-II. The mean service rate of server-II follows an exponential distribution with parameter 3 µ . The Laplace transform of the transient and steady state behavior of the model is considered and we obtained the expressions for the expected queue length

Culture of Efficient Marine Microalgae, Their Biochemical Composition and its Antibacterial Activity against Human Pathogens

Marine microalgae have been used for a long time as food for humans such as Chlorella vulgaris, Spirulina platensis and Nannochloropsis bacillaris and for animals in aquaculture. The biomass of these microalgae and the compounds they produce have been shown to possess several biological applications with numerous health benefits. The three marine microalgae (Chlorella vulgaris, Spirulina platensis and Nannochloropsis bacillaris) were collected from Vellar estuary, South east coast of India. These three microalgae were cultivated in respective media (BG11, Conway, and Zarrouk) and estimated their biochemical composition (Protein content, Carbohydrate (CHO) analysis, Total lipids, Chlorophyll, Carotenoids and antibacterial activity. Simultaneously, these cultures were cultivated in flask containing 500 ml of respective media at lab condition for a period of one month and their growth, pH, biomass, CO2 fixation and carbon content were determined. Based on the growth rate, the pH of three microalgae in media was observed at lab condition. During maximum growth and biomass, the pH was found to be ranged between 9 and 11 for Spirulina platensis; 7 and 9 for Chlorella vulgaris; 8 and 9 for Nannochloropsis bacillaris. The Spirulina platensis and Chlorella vulgaris reached maximum growth rate and produced maximum biomass. Further, Chlorella vulgaris and Spirulina platensis attained maximum biomass in media at lab condition, also fixed highest level of carbon dioxide in media but they did not produce maximum biomass, though the growth of Nannochloropsis bacillaris were found high in media at lab condition. Among the three microalgae, Chlorella vulgaris and Spirulina platensis produced highest biochemical (Protein estimation) compounds. Hence, Chlorella vulgaris and Spirulina platensis were selected as efficient microalgae for antibacterial activity against human pathogen. This study revealed that certain green algae and blue green microalgae having high growth, pH, CO2 fixation, carbon content and biochemical composition paves the way for pharmaceutical activity. Antibacterial activity against human pathogen (Klebsiella pneumoniae, Proteus mirabilis, Vibrio cholera, Salmonella typhi and Escherichia coli) was evaluated.The crude and fractionated extraction of Chlorella and Spirulina were dissolved in different solvents like ethanol, methanol, chloroform and diethyl ether. The extracts were applied to 6 mm dry sterile disc in aliquots of 30 μL of solvent, allowed to dry at room temperature and placed on agar plates seeded with microorganisms. The bacteria were maintained on nutrient agar plates and incubated at 37˚ C for 24 hrs. Zones of growth inhibition were measured after incubation from all the extracts and tested twice at a concentration of 30 mg disc-1 was evaluated for Chlorella and Spirulina with their potential health benefits.Keywords: Chlorella vulgaris, Spirulina platensis, Nannochloropsis bacillaris, CO2 fixation, Biochemical composition, Pharmaceutical activit

Performance Enhancement of MANET based on Cross-layered Reconfigurable Hierarchical Routing Protocol

High speed data communication is the demanding factor in both commercial and defence applications. Several algorithms are proposed to support the high-speed data exchange while ensuring the quality, performance and reliability. However, there is still a gap, citing various compatibility issues with variety of transceiver technologies. This paper proposes a novel algorithm for enhancing the performance of mobile ad-hoc networks using Free-Space Optics (FSO). The FSO has the natural ability to the interference while capable of large bandwidth and excellent compatibility. Low power and adaptability are the features with which it has contributed to the latest technologies like storage area network, wireless area network etc. The proposed work uses optical spheres with a multi-transceiver system and a cross-layered reconfigurable routing mechanism. Parameters such as delay, residual energy, throughput, and drop are verified for the Crosslayered Reconfigurable Hierarchical Routing Optical Sphere (CRHROS) protocol for varying numbers of optical transceivers. The proposed work also compares the performance of two traffic sources, Constant Bit Rate (CBR) and Variable Bit Rate (VBR), for the proposed algorithm

Biochemical and Functional Characterization of Mouse Mammary Tumor Virus Full-Length Pr77Gag Expressed in Prokaryotic and Eukaryotic Cells

The mouse mammary tumor virus (MMTV) Pr77Gag polypeptide is an essential retroviral structural protein without which infectious viral particles cannot be formed. This process requires specific recognition and packaging of dimerized genomic RNA (gRNA) by Gag during virus assembly. Most of the previous work on retroviral assembly has used either the nucleocapsid portion of Gag, or other truncated Gag derivatives—not the natural substrate for virus assembly. In order to understand the molecular mechanism of MMTV gRNA packaging process, we expressed and purified full-length recombinant Pr77Gag-His6-tag fusion protein from soluble fractions of bacterial cultures. We show that the purified Pr77Gag-His6-tag protein retained the ability to assemble virus-like particles (VLPs) in vitro with morphologically similar immature intracellular particles. The recombinant proteins (with and without His6-tag) could both be expressed in prokaryotic and eukaryotic cells and had the ability to form VLPs in vivo. Most importantly, the recombinant Pr77Gag-His6-tag fusion proteins capable of making VLPs in eukaryotic cells were competent for packaging sub-genomic MMTV RNAs. The successful expression and purification of a biologically active, full-length MMTV Pr77Gag should lay down the foundation towards performing RNA–protein interaction(s), especially for structure-function studies and towards understanding molecular intricacies during MMTV gRNA packaging and assembly processes
