Convolutional Neural Network Based Fault Detection for Rotating Machinery

This review covers advances in electrochemical and biochemical sensor development and usage during 2010 and 2011 In choosing scholarly articles to contribute to this review, special emphasis was placed on work published in the areas of reference electrodes, potentiometric sensors, voltammetric sensors, amperometric sensors, biosensors, immunosensors, and mass sensors In the past two years there have been a number of important papers, that do not fall into the general subsections contained within the larger sections Such novel advances are very important for the field of electrochemical sensors as they open up new avenues and methods for future research Each section above contains a subsection titled “Other Papers of Interest” that includes such articles and describes their importance to the field in general For example, while most electrochemical techniques for sensing analytes of interest are based on the changes in potential or current, Shan et al1 have developed a completely novel method for performing electrochemical measurements In their work, they report a method for imaging local electrochemical current using the optical signal of the electrode surface generated from a surface plasmon resonance (SPR) The electrochemical current image is based on the fact that the current density can be easily calculated from the local SPR signal The authors demonstrated this concept by imaging traces of TNT on a fingerprint on a gold substrate

Full articles and reviews were primarily amassed by searching the SciFinder Scholar and ISI Web of Knowledge Additional articles were found through alternate databases or by perusing analytical journals for pertinent publications Due to the reference limitation, only publications written in English were considered for inclusion Obviously, there have been more published accounts of groundbreaking work with electrochemical and biochemical sensors than those covered here This review is a small sampling of the available literature and not intended to cover every advance of the past two years The literature chosen focuses on new trends in materials, techniques, and clinically relevant applications of novel sensors To ensure proper coverage of these trends, theoretical publications and applications of previously reported sensor development were excluded

We want to remind our readers that this review is not intended to provide comprehensive coverage of electrochemical sensor development, but rather to provide a glimpse of the available depth of knowledge published in the past two years This review is meant to focus on novel methods and materials, with a particular focus on the increasing use of graphene sheets for sensor material development For readers seeking more information on the general principles behind electrochemical sensors and electrochemical methods, we recommend other sources with a broader scope2, 3 Electrochemical sensor research is continually providing new insights into a variety of fields and providing a breadth of relevant literature that is worthy of inclusion in this review Unfortunately, it is impossible to cover each publication and unintentional oversights are inevitable We sincerely apologize to the authors of electrochemical and biochemical sensor publications that were inadvertently overlooked

On the Application of Strain Gauges for a Structural Member Subjected to Complex Type of Loading

In recent times Hydrostatic journal bearings have received considerable amount of attention by the researchers on account of their excellent performance as compared to other class of bearings. The objective of the present paper is to presents an analysis of a four-pocket capillary-compensated worn hydrostatic journal bearing system. The FEM has been used to solve the Reynolds equation governing the flow of lubricant in the clearance space of a multirecess journal bearing system together with capillary restrictor flow equation as a constant. The bearing performance characteristics of a capillary compensated 4-pocket worn hydrostatic journal bearing have been presented for a wide range of values of external load and nondimensional wear depth parameters. The numerically simulated results of bearing characteristics parameters in terms of maximum fluid-film pressure, minimum fluid-film thickness, lubricant flow rate and fluid film reaction have been presented. The simulated results suggest that for an accurate prediction of bearing characteristics data it is essential to include the effect of wear in the analysis of the hydrostatic journal bearing system.Copyright © 2009 by ASME

Analysis of a Worn Multirecess Hydrostatic Journal Bearing System

In-situ composites offer a wide selection of constituent and an opportunity for understanding the mechanisms their mechanical properties so that intelligent decisions may be taken while tailoring a composite for a specific application. Properties of material are basically governed by the constituent phases and their distribution and depend on the composition and processing conditions. In the present investigation tribological properties of hot forged Cu-Cr-SiC and annealed after hot forging system are proposed to be studied by addition of Cr and SiC into the copper matrix. The effect of constituent phases on tribological properties after hot forged and annealed after hot forged has been investigated. It is expected to enhance the understanding of tribological properties in this presented work for the hot forged Cu-Cr-SiC composite system.

Dry Sliding Wear Behavior of Hot Forged and Annealed Cu-Cr-SiС In Situ Composite

Elastomers are widely used in various engineering applications due to their huge elasticity and good dynamic behavior. One of the elastomeric elements is rubber blocks, which are used in many applications, such as vibration isolators, bumpers, shock absorbers, dampers, etc. In this research, the impact on the ride index due to the deflated state of the air spring with various kinds of hyperelastic materials is analyzed by the finite element method. The stress–energy function of rubber materials is first diagnosed, and Poisson’s ratio defined the volumetric terms. The rubber isolator’s stress is studied based on the finite element model, and the structure is improved. It is observed that for the deflated state of the air spring, laminated rubber isolation diminishes the muscular amount of structural responses compared to the conventional rubber base structures, and improves the ride comfort. This study would assist in doing finite element analysis of the secondary suspension system and other vibration-damping components.

A Comparative Study on the Behavior of Ride Quality Due to Deflated State of Air Spring using Different Properties of Hyperelastic Material

Aim: The present study was conducted to investigate the biocontrol potential of fluorescent pseudomonads in- vitro and in-vivo responsible for causing sheath blight of rice. Methodology: Indigenous isolates (20 nos.) of fluorescent pseudomonads, collected from the rhizosphere of basmati paddy fields from different locations of Jammu province, which were further characterized for their bio-control activity against Rhizoctonia solani causing sheath blight of rice under laboratory and glasshouse conditions at Division of Plant Pathology, Faculty of Agriculture, SKUAST- Jammu, ChathaResults: On the basis of biochemical tests, isolate Fp1, Fp2, Fp4, Fp5, Fp6, Fp7, Fp9, Fp11, Fp17 and Fp18 were able to grow at 4°C and were identified as Pseudomonas fluorescens, whereas, isolate Fp3, Fp8, Fp10, Fp12, Fp13, Fp14, Fp15, Fp16, Fp19 and Fp20 which grew at 41°C and utilized the acetamide were identified as Pseudomonas aeruginosa. Under in vitro conditions, out of ten isolates (Fp1- Fp10), Fp6 showed maximum per cent inhibition (84.09 and 86.66) of mycelial growth of R. solani, followed by Fp1 (81.81and 84.89), whereas, minimum inhibition was observed by Fp8 (43.40 and 64.00) on PDA and NA media, respectively, using dual culture assay. All the isolates reduced the germination of R. solani sclerotia with range of 49.05-90.87% and also enhanced the vigour index of the rice seedlings ranging from 595.05 to 1683.27. In detached leaf assay rice leaves treated with suspension of Fp6 isolate significantly showed minimum lesion length (12.66 mm) with maximum per cent reduction of lesion (81.91%) as compared to untreated control (70.00 mm). The treatment T4 (P. fluorescens) and T8 (P. aeruginosa) (seed soaking + seedling dip +foliar spray) showed disease intensity of 10.94 and 14.06 per cent with 42.19 and 39.07 per cent disease reduction, respectively, as compared to untreated control. Interpretation: Due to dominance of fluorescent pseudomonads (P. fluorescens and P. aeruginosa) in the rice rhizosphere and diverse mechanism of action, it had the potential for reducing sheath blight incidence of rice caused by R. solani.
