A model to investigate the dynamic-pull-in characteristics of a functionally carbon nanotube (FG-CNT) reinforced polymer co...

Calcium copper titanate (CCTO) sputtering target was fabricated by adopting solid state route. CCTO thin films were deposited on p-Si (100) substrates by RF magnetron sputtering technique at room temperature with RF power and deposition pressure of 105 W and 5 × 10-3 mbar, respectively. Post deposition annealing was carried out for the sputtered samples at different temperature ranging from 650 °C to 950 °C in air atmosphere. From X-ray diffraction, evolution of CCTO crystalline peaks was ob...

In this article, we present a Neuromorphic Person Re-Identification (NPReId) framework to establish the correspondence among individuals observed across two disjoint camera views. The framework comprises three modules (observation, cognition, and contemplation), inspired by the Form-and-Color-and-Depth (FACADE) theory model of object recognition system. In observation module, a semantic partitioning scheme is introduced to segment a pedestrian into several logical parts, and an exhaustive se...

During the summer monsoon period India received above normal rainfall in 2013 and below normal rainfall in 2009. The present study aims to understand the variability of sea level anomalies (SLA) and mesoscale eddies during the contrasting summer monsoon years of 2009 and 2013 over the Bay of Bengal. To accomplish this satellite derived daily gridded SLA product with 0.25° spatial resolution is examined. Oceanic mesoscale eddies are identified from the gridded SLA using widely adopted Oku...

Molybdenum and vanadium complexes of various O-N and/or N-S donor scaffolds are appealing candidates in the search for new diagnostic and therapeutic agents. Examples of molybdenum mediated C-C coupling and –C=N bond cleavage reactions are interesting and sparse in literature. Also, in contrast to the well–known molybdenum(VI/IV) complexes few structural reports are there of monooxido MoIV complexes, generated through “oxotransfer” processes. On another hand, in comparison to the well-kn...

Soils of low salt concentration that dislodge easily and quickly, when comes in contact with water are called dispersive soils. These are unstable and disintegrate or erodible. These soils are present in many parts of the world such as India, United States, Australia, Greece, America, South Africa, Thailand, and others. They pose serious problems in stability of earthen structures, road fills, and other engineering structures. Even if there are simple methods to identify the dispersivity...

This paper presents an efficient method to reconstruct 3D point cloud from an arbitrary number of views of an object of interest. Nowadays, Light Detection and Ranging (LIDAR) devices are used in autonomous vehicles and robots to get the 3D measurements. LIDAR contains laser scanners which directly gives the 3D information. However, these scanners are very expensive and prone to interferences and noise due to bulk hardware present in the device. To address this problem, mobile phone c...

Inflation affects the growth rate positively or remains silence up to some level; beyond certain level it affects the growth rate negatively. That level of inflation is known as threshold level of Inflation. This paper estimates the threshold level of inflation for India from the period of April 2006 to May 2015. The threshold level of inflation treated as a regime point and the whole sample is divided into two different regimes i.e. from April 2006 to March 2013 and April 2013 to May 20...

Camera Model Identification is the digital forensic problem of identifying the source of an image under question, i.e., to map the image to its source device. This assists forensic analysts to map a suspect's camera with a possibly illegal image repository, or to attribute an image under question to its legitimate source. Counter-forensic attacks to Camera Model Identification techniques, primarily comprise of image anonymization. Image Anonymization is a technique adopted by an intelligent a...

Our society gets huge benefits from the water storage dams, but the consequences are devastating if a dam fails. It causes extensive damage to the life and properties mostly due to short warning time. Important factors governing failure studies are the breaching parameters that help to quantify the risk associated with dam break floods. Many empirical equations have been developed for predicting the breaching parameters associated with peak outflow, and these equations are generally devel...

Tropical cyclones (TC) activity over North Indian Ocean (NIO) and the atmospheric and oceanic parameters responsible for the associated changes need to be analysed. The study is conducted by dividing the whole considered period into two parts i.e. pre-warming period (PWP) from 1880 to 1946 and 1947 onwards as current warming period (CWP) on the basis of sea surface temperature (SST) variation. During CWP, annual TC genesis trend over NIO and BOB is decreasing severely in contrast to that...

Chennai stood still by the extreme rainfall event that occurred in November-December 2015. It received ~300% excessive rainfall from the mean observed amount of 407.4 mm for the month of November. The record-breaking rainfall created history by exceeding the 24-hour rainfall (290 mm) on 1st and 2ndDecember. For analysing this event series, a multi fold observational and modelling approach is adopted in this study. Simulation of the whole event is performed in six experiments using Noah b...

The influence of curing conditions on strength and microstructure of lime-amended fly ash is presented in this paper. A series of compaction, UCS and CBR tests are carried out by varying the lime content from 0 to 12%. The curing of specimen is done for 0 to 60 days under temperature of 10ºC to 90ºC. The test results showed that an increase of either lime content or curing period increases the UCS and CBR values. The curing temper-ature also influences the rate of strength gain and formation ...

Extensive laboratory model tests were conducted on a rectangular embedded foundation resting over homogeneous sand bed and subjected to an eccentric load to determine the ultimate bearing capacity. The depth of embedment varies from 0 to 1B with an increment of 0.5B; where B is the width of foundation and the eccentricity ratio (e/B) varies from 0 to 0.15 with an increment of 0.05. Based on the laboratory model test results, a neural network model is developed to estimate the reduction factor...

Laboratory model tests have been conducted on a strip foundation resting over multi-layered geogrid-reinforced dense and loose sand subjected to inclined load. Based on the laboratory model test results, a neural network model is developed to estimate the reduction factor for bearing capacity. The reduction factor obtained by ANN can be used to estimate the ultimate bearing capacity of an inclined loaded foundation from the ultimate bearing capacity of a vertically loaded foundation. A thorou...

Thin plated structures of different geometries are widely used in the field of civil, mechanical, aerospace and naval engineering. The structures can be subjected to any time varying loading like blast or impact loads. This paper thus presents nonlinear transient vibration analysis of arbitrary thin plates using a superparametric element. The geometry of the plate is represented by cubic serendipity shape function and the displacement field is defined by an ACM plate bending element along wit...

Chilika lake is a brackish water lagoon as well as the largest coastal lagoon in India and the second largest lagoon in the world, of Odisha state on the east coast of India covering an area of over 1,160 km2. The size of the lagoon is decreasing over the years due to large siltation of the rivers joining Chilika lake and dredging is required to deal with siltation. Utilization of dredging sand from Chilika for construction purposes is a sustainable method to deal with siltation. In the prese...

Red mud is an alkaline by-product which is generated during the processing of bauxite. Generally red mud is considered as a waste material which is disposed into large lagoons. Red mud contains large amount of Fe2O3, Al2O3 and small amounts of CaO, SiO2 and some valuable metals such as titanium however it devoid of reactive alumino-silicates. As red mud is highly alkaline, it is possible to stabilize red mud by adding industrial waste materials rich in alumino-silicates by geopolymerization. ...
