Numerical and experimental investigation of FBG strain response at cryogenic temperatures

Strain response of FBG sensors are investigated at various temperatures from 298 K to 4.2 K. Numerical modelling is carried out for acrylate coated, substrate-free fiber Bragg grating (FBG) sensors at room temperature of 298 K and cryogenic temperatures of 77 K, 10 K and 4.2 K. A 1550 nm Bragg wavelength (λB) FBG sensor is modelled and simulated for applied strain (ε) ranging from 0 to 800 µm/m. The Bragg wavelength shifts (ΔλB) thus obtained are compared with the experimentally investigated values obtained by subjecting the FBG sensor to axial strain, with its sensing part not being bonded to any surface. The MTS25 tensile machine with a cryostat under vacuum conditions (10-4 mbar pressure) is used for the experiments and the required temperatures are maintained using liquid Nitrogen (LN2) and compressed Helium gas (He). The Bragg wavelength shift (ΔλB) versus induced strain (ε) is regressed with a linear polynomial function and the strain sensitivity obtained in both the cases are discussed

In G. corticola var. cylindrica the yield of agar ranged from 33.1 to 48.6% and gel strength from 12 to 67 gm/cm'

Seaweeds-products, processing and utilization

Seaweeds-products, processing and utilization Marine macroalgae which are popularly termed as Seaweeds belong to the primitive group of nonflowering plants known as Thallophyta. They are autotrophic plants and grow in the intertidal and subtidal regions of the sea

Distribution and seasonal changes of marine algal flora from seven localities around Mandapam

Studies on the distribution and seasonal changes in tHe marine aLgal flora was made for a period of one year from July '83 to June '84 by making fortnightly collection of algae from intertidal and subtidal regions upto 1.0 m depth at seven localities along Mandapam coast namely Rameswaram, Pamban, Krusai Island, Thonithurai, Seeniappa Darga, Pudumadam and Kilakarai. Totally 104 algal species belonging to the groups Chlorophyta, Phaeophyta, Rhodophyta and Cyanophyta were recorded from these places. A maximum number of 77 algal species at Krusadai Island and a minimum number of 35 species at Rameswaram were recorde

An exploratory study of ERM perception in Oman and proposing a maturity model for risk optimization

Enterprise Risk management is a process vital to enterprise governance which has gained tremendous momentum in modern business due to the dynamic nature of threats, vulnerability and stringent regulatory requirements. The business owners have realized that, risk creates opportunity which in turn creates value. Identifying and mitigating risk proactively across the enterprise is the purview of Enterprise Risk Management (ERM).However, key errors in the ERM process such as misinterpretation of statistical data, overlooking change management, inadequate attention to supply chain interdependencies, excessive trust of insiders and business partners, ambiguous grouping of risks and poor documentation has contributed significantly to the failure of ERM. To examine the ERM perception in Oman, the authors have conducted a survey among various risk management practitioners. Based on the findings, the authors have broadly classified risk into three types namely business risks, technical risks and regulatory risks and threat vs. consequence mapping is defined to provide direction to moderately group risks. Further, this article defines various ERM approaches including due diligence, probabilistic risk analysis, scenario-based analysis and system analysis which offers a wide range of decision-support tools to the management

Tool Wear and its Effect on Residual Tensile Strength in Drilling of Quartz Cyanate Ester Polymeric Composite

Quartz-Fibre-Reinforced cyanate ester Plastics (QFRP) has superior performance in terms of mechanical, electromagnetic properties and are being widely used in military applications. Drilling is the general machining process for making hole to join the composite part to another sub-assembly. This study presents an influence of optimized drilling parameters on carbide tool wear and its impact on hole characteristics in QFRP composite. The aim is to achieve the optimum use of drill during the drilling process from application perspective without compromising the quality. In addition, the effect of tool wear and its impact on residual tensile strength of quartz composite are studied. The dominant wear mechanism observed is flank wear caused by the abrasive nature of the quartz fibre. The tool wear and delamination factor after drilling 200 holes are 186 µm and 1.40 respectively. The residual strength is affected by the tool wear due to relatively poor interlaminar property between fiber and resin in this quartz composite. The residual strength of quartz specimen drilled with the tool after drilling 200 holes is 14 % lower than the property of specimen drilled with fresh drill. The highlight of the present work is a combined analysis of wear in the tool, delamination induced and residual strength of quartz specimen. The results of this study strengthen the understanding of the drilling process of quartz polymeric composite material in aerospace applications

Present status of seaweed exploitation and seaweed industry in India

The survey of marine algal resources conducted by CMFRI along Tamil Nadu coast during 1971-76. The standing crop from the total area of 17,125 ha was estimated at 22,044 tonnes (wet wt.), consisting of 1,709 tonnes of agarophytes, 10,266 tonnes of alginophytes and 10,069 tonnes of other seaweeds. The resources of the commercially important species are 74 tonnes of Gelidiella acerosa, 914 tonnes of Gracilaria spp., 798 tonnes of Hypnea spp., 9,381 tonnes of Sargassum spp. and 714 tonnes of Turbinaria spp. The year to year fluctuation in the quantity of alginophytes landed was due to the variation in the demand of the major algin producing industries based on their supply orders for sodium alginate

Robust Face Recognition Using Enhanced Local Binary Pattern

Face recognition is an emerging research area in recognition of the people. A novel feature extraction technique was introduced for robust face recognition. Enhanced Local binary pattern (EnLBP) divided the image into sub regions. For each sub region, the salient features are extracted by obtaining the mean value of each sub region. In LBP, each pixel was replaced by applying LBP into each sub region. In this paper, the mean value of sub region was replaced for the sub region. It reduced the dimension of the image and extracts the salient information on each sub region. The extracted features are compared with similarity measures to recognize the person. EnLBP reduces the operation time and computational complexity of the system. The experimental results were carried out in the standard benchmark database LFW-a. The proposed system achieved a higher recognition rate than other local descriptors
