This paper presents the dependency of collector efficiency on the radial dimensions of the multi-stage depressed collector. In addition, an approach to reduce the radial dimensions of the collector without significantly compromising the collector efficiency using external magnetic field in the collector region would also be presented.

It is observed that volume component is similar in both the decompositions. However, this component is over-estimated as compared to odd and even bounce scattering mechanisms for all land cover targets. The supervised maximum likelihood classification has been performed in this paper. Apart from this, the same area was also monitored using optical remote sensing imagery. An overall classification accuracy of above 85 % is observed using hybrid SAR and optical data.

One function of the nervous system that can be exploited by neuromodulation is regulation of disease intensity. Optimal interfacing of devices with the nervous system requires suitable models of peripheral nerve systems so that closed-loop control can be utilized for therapeutic benefit. APPROACH We use physiological data to model afferent signaling in the vagus nerve that carries information about inflammation in the small intestine to the brain. MAIN RESULTS The vagal nerve signaling system is distributed and complex; however, we propose a class of reductive models using a state-space formalism that can be tuned in a patient-specific manner. SIGNIFICANCE These models provide excellent fits to a large range of nerve recording data but are computationally simple enough for feedback control in i...

Revegetation helps in restoring the productivity of soil by reducing soil erosion and protecting soil from further degradation during land reclamation. There are several approaches to revegetation, such as coir matting, plantation of lemon grass, vetiver grass and local (host) plants, which may be used effectively to stabilise iron ore mines dumps. The plantation of local plants through the Miyawaki method has been found more effective than the conventional methods of plantation. This method involves plantation of a number of local (host) plants, such as Karanj (Ponganna Pinnata), Shisham (Dalbergia Sissoo), Neem (Azadirachta India), Sal (Shorea Robusta), Kendu (Diospyros Melanoxylon), Amla (Phyllanthus Emblical) Jamun (Syzgium Cumini), Banyan (Ficus Benghalensis) and Krishnachura (Delonix Regia), closely spaced in a dump slope or small pit.

India is the ‘Incredible’ source of languages that diversify in various geographical boundaries. Constitutional provision with its amendments its representatives and users give oriented multidimensional safeguards to nation building. Presently, wants and needs have current results disengaged with social participation, inheritance less consideration or forward to next generation and digital addiction following declining language-centred services also measures that give languages less importance. This paper emphasises to delimit the boundaries related to language services and connectivity with languages for the welfare of all people in terms of libraries as a resource centre of language environment. The library is one place centre where universal data, information and knowledge about any language retrieve in desired medium and formats by individual user/residents. To describe the important role of libraries for languages, a model is prepared called ‘Libraries are mirrors’ and summarise mainly under the following steps such as Role of Libraries and Librarians, Bottom-to-top approach shows the users centric inhouse activities, Languages resources classification according to dewy Decimal Classification. Top-to-bottom approach distinguishes the dissemination of services at various levels such as anticipatory, reprographic, reference and referral service with web-based open access catalogue. Libraries provide translation of source languages into target languages with multidimensional behaviour. Important links are lists to find languages source and service. Some important suggestions put forth for the development and welfare languages and its users.

This makes researchers interested to study the hybrid polarimetric SAR data for various remote sensing applications. In this paper, backscatter signals and scattering decomposition from hybrid polarimetric Radar Imaging Satellite-1 (RISAT-1) SAR data for various land cover targets have been studied. Even though SAR transmits right circular polarized signal, the return RADAR signal may be partially polarized (which means sum of completely polarized and un-polarized signal). The RADAR return signal and scattering decomposition varies for different land cover targets depending on the geometrical, structural and electrical properties of the target under consideration. Here, Stokes classical parameters are used to study the RA...

The variation of horizontal and vertical length of L-strip has been investigated in circular disk patch antenna. The bandwidth of the antenna is found inversely proportional to the horizontal length of L-strip whereas it is almost invariable with vertical length of L-strip. Typically the bandwidth of this antenna is found to be 16.63 % with maximum gain of 8.515 dBi. Further L-strip proximity fed U-slot loaded disk patch is studied. In this geometry bandwidth of the antenna increases up to 37.01% when the vertical length of L-strip is 6.5 mm but there is marginal effect in the bandwidth with the variation of horizontal length of L-strip. Gain of this antenna varies from 8.195 dBi to 7.015 dBi for the entire operating frequency band. Radiation pattern of both the antennas is stable across the operating band.

This bound, obtained from detailed numerical simulations and theoretical estimates, provides compelling evidence not only for recent conjectures lambdasimsqrtT\lambda \sim \sqrt{T}lambdasimsqrtT for chaotic, equilibrium, classical many-body systems, as well as, numerical results from frustrated spin systems, but also, remarkably, show that lambda\lambdalambda scales linearly with the degrees of freedom in a finite-dimensional, classical, chaotic system.

This IoT infrastructure generates an enormous amount of data in the form of city-scale physical measurements and public opinions, constituting big data. Smart cities aim to efficiently use this wealth of data to manage and solve the problems faced by modern cities for better decision making. However, interpretation of the massive amount of smart city generated big data to create actionable knowledge is a challenging task. Aggregation and Summarization (data clustering) is a useful tool to create knowledge from raw data from different sources. However, traditional data clustering algorithms are not suitable for unlabelled smart city data owing to its high volume and generation velocity and limited experience about generating phenomenon. This thesis presents a novel framework for clustering tendency assessment for big data: clusiVAT, which provides...

Many herbal medicines have been used as alternative therapy for depression. Mucuna pruriens, belonging to family Fabaceae, has been used in traditional Ayurvedic medicine for various ailments. Present study was undertaken to evaluate the anti-depressive activity of acute and chronic administration of Mucuna pruriens in forced swimming test (FST). Methods: The study was conducted on 30 male Swiss albino mice. Animals were divided into five groups (n = 6 /group): control (normal saline, p.o.), the three doses of Mucuna pruriens (100, 200, 400 mg/kg, p.o.) and standard dose of imipramine (20 mg/kg, p.o.) for 30 days treatment. The pharmacologically validated model forced swimming test (FST) was used to take as a measure of antidepressant activity. Results: Mucuna pruriens showed dose dependent decrease in immobility time. At the dose of 200 mg/kg it reduced immobility time significantly on day 20 and day 30 whil...
