The heteroatom-containing porphyrin analogues or core-modified porphyrins that resulted from the replacement of one or two pyrrole rings with other five-membered heterocycles such as furan, thiophene, selenophene, tellurophene, indene, phosphole, and silole are highly promising macrocycles and exhibit quite different physicochemical properties compared to regular azaporphyrins. The properties of heteroporphyrins depend on the nature and number of different heterocycle(s) present in place of pyrrole ring(s). The heteroporphyrins provide unique and unprecedented coordination environments for metals. Unlike regular porphyrins, the monoheteroporphyrins are known to stabilize metals in unusual oxidation states such as Cu and Ni in +1 oxidation states. The diheteroporphyrins, which are neutral macrocycles without ionizable protons, also showed interesting coordination chemistry. Thus, significant progress has been made in last few decades on core-modified porphyrins in terms of their synthesis, their use in building multiporphyrin arrays for light-harvesting applications, their use as ligands to form interesting metal complexes, and also their use for several other studies. The synthetic methods available in the literature allow one to prepare mono- and diheteroporphyrins and their functionalized derivatives, which were used extensively to prepare several covalent and noncovalent heteroporphyrin-based multiporphyrin arrays. The methods are also developed to synthesize different hetero analogues of porphyrin derivatives such as heterocorroles, heterochlorins, heterocarbaporphyrinoids, heteroatom-substituted confused porphyrins, and so on. This Review summarizes the key developments that have occurred in heteroporphyrin chemistry over the last four decades. © 2016 American Chemical Society.

A linear stability analysis of convection in viscoelastic liquids with temperature-dependent viscosity is studied using normal modes and Galerkin method. Stationary convection is shown to be the preferred mode of instability when the ratio of strain retardation parameter to stress relaxation parameter is greater than unity. When the ratio is less than unity then the possibility of oscillatory convection is shown to arise. Oscillatory convection is studied numerically for Rivlin-Ericksen, Maxwell and Jeffreys liquids by considering free-free, rigid-rigid and rigid-free isothermal/adiabatic boundaries. The effect of variable viscosity parameter is shown to destabilize the system. The problem reveals the stabilizing nature of strain retardation parameter and destabilizing nature of stress relaxation parameter, on the onset of convection. The Maxwell liquids are found to be more unstable than the one subscribing to Jeffreys description whereas the Rivlin-Ericksen liquid is comparatively more stable. Free-free adiabatic boundary combination is found to give rise to a most unstable system, whereas the rigid isothermal rigid adiabatic combination gives rise to a most stable system. The problem has applications in non-isothermal systems having viscoelastic liquids as working media. © 2009 Elsevier Masson SAS. All rights reserved.

In a multi-hop WSN a sensor node spends most of its energy for relaying data packets due to which energy reduction is one of the major issue in the designing of a wireless sensor network to prolong the lifetime of a network. One of the solutions of this problem is to shorten the hop distance a sensor's data that has to travel until reaching the sink. These distances can be reduced effectively by deploying multiple sinks instead of one and every sensor communicates with its closest sink. In order to achieve the shortest distances the sinks have to be deployed carefully. In this paper we have considered the problem of optimal deployment of k sink nodes in a wireless sensor network for minimizing average hop distance between sensors and its nearest sink with maximizing degree of each sink node which can solve hot spot problem which is another critical issue of WSN design. Given a wireless sensor network where the location of each sensor node is known, partition the whole sensor network into k disjoint clusters and place sink nodes optimally. We propose multi sink placement algorithm, based on Particle swarm optimization. The simulation results show that our proposed optimization based algorithm perform better over algorithm without optimization. © 2013 IEEE.

V-65 (Russian grade) is commercial Aluminium alloy used in making rivets in aerospace applications as it exhibits relatively high shear strength and plasticity. Controlling properties of this alloy by the addition of second phase particles in the form Zirconium that hinders grain growth by exerting Zener drag is discussed in this work. The alloys were subjected to differential thermal analysis and peaks were observed at 4190c, indicating the dissolution of Al3Zr particles. The alloy was warm extruded at 300 & 3500c and the kinetics of Recrystallization was followed by image analysis on samples of recrystallized at 4200c for various times assuming that short duration of anneal would not dissolve Al3Zr because of diffusion coefficient of Zirconium in Aluminium is low. Detailed microstructure analysis indicated the Al3Zr particles exerted pinning pressure on grain boundaries effectively producing fine grains. These results were justified by the volume fraction analysis of grains. Transmission Electron Microscopy was also conducted and the fine particles were found to be Al3Zr particles with L1-2 crystal structure and lattice parameter 4.08 A0.The cube grains were identified by etch pit technique and it was found that addition of Zr did not alter the number of cube grains. These cube grains facilitate the alloy in deep drawing and its application in the fuselage of an aeroplane. © 2017 Elsevier Ltd. All rights reserved.

An experimental study was carried out in order to investigate the influence of volume of paste and powder on the fluid-solid system of SCC. This paper presents the results of the compressive strength of SCC mixtures. Tests have been conducted on 57 SCC mixes, with constant water content, varying from 175 l/m3 to 210 l/m3 with three different paste contents and 21 comparable normal concrete mixes. Among the different water contents and w/c ratios studied in each series, w/c ratio and more importantly water is kept constant. The results indicate that the compressive strength of SCC increases with paste content for the same w/c ratio. The existence of optimal value of volume of paste was observed which was independent of the water content, indicating the importance of volume of paste along with w/c ratio in the mix design. Considerable increase in compressive strength over comparable normal concrete was noticed when the paste content of SCC was enhanced from 0.38 to 0.43. Suitable modification factors are suggested to the standard Abram's curve for normal concrete and thus the increase can be suitably factored in concrete mix design to economize on cement content.

In this study, the author investigates the problem of lifetime enhancement of mobile nodes in mobile ad hoc networks. Here, the author uses two metrics namely, residual battery capacity of the node and non-critical node to route the data packets from the source to the destination. The proposed model uses the non-critical node if all the nodes contain residual battery capacity above the threshold value. The proposed model has been simulated using Qualnet Simulator-4.5. The proposed model has compared against the existing algorithms such as minimum total transmission power routing, conditional max-min battery capacity routing and lifetime prediction routing. From the results, the author concludes that the proposed model has reached at the top position in terms of the number of survived nodes, energy saving and number of nodes with zero remaining energy. © 2011 © The Institution of Engineering and Technology.

Wireless ad hoc networks are growing important because of their mobility, versatility, and ability to work with fewer infrastructures. The mobile ad hoc network is an autonomous system consisting of mobile nodes connected with wireless links. Establishing a path between two nodes is a complex task in wireless networks. It is still more complex in the wireless mobile ad hoc network because every node is no longer as an end node and an intermediate node. In this paper, it focuses on design of connectionless routing protocol for the wireless ad hoc networks based on the mobile agent concept. The proposed model tries to discover the best path taking into consideration some concerns like bandwidth, reliability, and congestion of the link. The proposed model has been simulated and tested under various wireless ad hoc network environments with the help of a different number of nodes. The results demonstrate that the proposed model is more feasible for providing reliable paths between the source and destination with the minimum control message packets over the network. It has delivered more number of packets to the destination over the network. Copyright © 2012 John Wiley & Sons, Ltd.

A mobile ad hoc network is a dynamic wireless network, which does not have fixed infrastructure. This paper presents a new multicast algorithm to increase the lifetime of node and network in the mobile ad hoc network. Here, it considers two metrics, namely residual-battery-capacity of the node and relay-capacity of the node to do multicasting from the source to a group of destination nodes. The proposed model is simulated using network simulator-2.33 and is tested under various conditions. The proposed model is compared with the existing algorithms such as multicast-incremental-power, lifetime-aware- multicast-tree, multicast-ad-hoc-on-demand-distance-vector protocol and multiple-path-multicast-ad-hoc on-demand vector. The proposed model shows the best results in terms of node lifetime, network lifetime and throughput. © 2001-2012 IEEE.

This paper focused on the design and implementation of a sliding mode controller with fuzzy logic tuning for depth control of an autonomous underwater vehicle (AUV). A fuzzy tuning approach to sliding mode control is employed for enhancing the tracking performance as well as reducing reaching time. The sliding surface can rotate or shift in the phase space in such a direction that the tracking behavior can be improved, which can be carried out using fuzzy tuning method. The reaching time and tracking error in the approaching phase can be significantly reduced. Experimental results indicate the effectiveness of the proposed controller in dealing with model uncertainties, nonlinearities of the vehicle dynamics and environmental disturbances caused by ocean currents and waves.
