Opis:
Most plates used in engineering structures such as aircraft wings, ship ducts and buildings, although quite capable of resisting tensile loads, are poor in withstanding compression. In order to avoid premature failure under compression, it is important to know buckling behavior of the plate. This article primarily deals with the analytical study of buckling behavior of a carbon nanotube reinforcing polymer composite plates based on the first order shear deformation theory by employing Mori-Tanaka micromechanics approach to obtain elastic properties. In this investigation, an attempt is made for evaluating the effect of plate thickness, CNT volume fraction, stacking sequence and CNT radii on the buckling of plates.

Opis:
Coefficient of Variation (C.V) is a unitless measure of dispersion. Hence it is widely used in many scientific and social investigations. Although a lot of work has been done concerning C.V in the infinite population models, it has been neglected in the finite populations. Many areas of applications of C.V involves the finite populations like the use in official statistics and economic surveys of the World Bank. This has motivated us to propose six new estimators of the population C.V. In finite population studies regression estimators are widely used and the idea is exploited to propose the new estimators. Three of the proposed estimators are the regression estimators of the C.V for the study variable while the other three estimators makes use of the regression estimators of population mean and variance to estimate the ratio , the population C.V for the study variable. The bias and mean square error (MSE) of these estimators were derived for the simple random sampling design. The performance of these estimators is compared using two real life data sets. The simulation is carried out to compare the estimators in terms of coverage probability and the length of the confidence interval. The small sample comparison indicates that two of the proposed estimators perform better than the sample C.V. The regression estimator using the information on the Population C.V of the auxiliary variable emerges as the best estimator.

Opis:
This paper presents the review concerning mechanical properties of bone and the miniature specimen test techniques. For developing a realistic understanding of how factors such as moisture content, mineralization, age, species, location, gender, rate of deformation etc. affect the mechanical properties of bone, it is critical to understand the role of these factors. A general survey on existing research work is presented on this aspect. The essential features of miniature specimen test techniques are described, along with the application of small punch test method to evaluate the mechanical behavior of materials. The procedure for the determination of tensile and fracture properties, such as: yield strength, ultimate strength, ductility, fracture toughness etc. using small punch test technique have been described. The empirical equations proposed by various investigators for the prediction of tensile and fracture properties are presented and discussed. In some cases, the predictions of material properties have been essentially made through the finite element simulation. The finite element simulation of miniature specimen test technique is also covered in this review. The use of inverse finite element procedure for the prediction of uniaxial tensile constitutive behaviour of materials is also presented.

Opis:
Pongamia pinnata, a tree bearing oil seeds, has been one of the prime focus among nonedible oil sources for biodiesel production in most parts of India. The oil cake obtained after the extraction of oil serves as an adequate source of cellulose, hemicellulose, proteins, lipids, and starch. The scarce literature data available suggest very low conversion rate of complex sugars to fermentable sugars and further to bioethanol. In the present work, a sulfuric acid hydrolysate obtained from Pongamia oil cake (POC) under microwave irradiation was anaerobically fermented using Bacillus cereus ATCC 14579. Under anaerobic and acidic conditions, the process parameters affecting the bioethanol production efficiency (BPE) were screened and optimized using statistical experimental designs. Of the seven parameters screened (glucose concentration, yeast extract as nitrogen source, agitation speed, pH, inoculum size, fermentation time, and temperature), only 3 were found to be significant and to increase BPE. The significant parameters were optimized using the Box-Behnken experimental design to obtain an optimal condition of 9 g/l reducing sugars, pH 4.6 maintained with acetate buffer, and fermentation period of 51 h that yielded 92% BPE with 4.2 g/l ethanol. Moreover, it was observed that the use of a buffer system to maintain broth pH, especially acetate buffer, significantly improved BPE. Low concentration of fermentation inhibitors is the key factor for improved BPE. The research outcome suggests that the production of dual fuel from Pongamia pinnata, viz. biodiesel and bioethanol, could not only improve the process economics but also reduce waste generation.

An unsteady magnetohydrodynamic (MHD) heat transfer two-fluid flow of ionized gases through a horizontal channel between parallel non-conducting plates, by taking Hall currents into account is studied. The governing partial differential equations that describe the flow and heat transfer under the adopted conditions are solved for the velocity and temperature distributions by a regular perturbation technique. Profiles for the velocity and temperature distributions as well the rates of heat transfer coefficient are presented graphically, and a parametric study is performed. The results reveal that the combined effects of the Hartmann number, Hall parameter, and the ratios of viscosities, heights, electrical and thermal conductivities have a significant impact on an unsteady MHD heat transfer two-ionized fluid flow characteristics.

Opis:
Digital speech copyright protection and forgery identification are the prevalent issues in our advancing digital world. In speech forgery, voiced part of the speech signal is copied and pasted to a specific location which alters the meaning of the speech signal. Watermarking can be used to safe guard the copyrights of the owner. To detect copy-move forgeries a transform domain watermarking method is proposed. In the proposed method, watermarking is achieved through Discrete Cosine Transform (DCT) and Quantization Index Modulation (QIM) rule. Hash bits are also inserted in watermarked voice segments to detect Copy-Move Forgery (CMF) in speech signals. Proposed method is evaluated on two databases and achieved good imperceptibility. It exhibits robustness in detecting the watermark and forgeries against signal processing attacks such as resample, low-pass filtering, jittering, compression and cropping. The proposed work contributes for forensics analysis in speech signals. This proposed work also compared with the some of the state-of-art methods.

Opis:
The shift in Multi-User Multiple Input Multiple Output (MU-MIMO) has gained attention due to its wide support in very high throughput Wireless Local Area Networks (WLANs) such as the 802.11ac. However, the full advantage of MU-MIMO can be utilized only with proper user selection and scheduling. Also, providing Quality of Service (QoS) support is a major challenge for these wireless networks. Generally, user scheduling is done with the acquisition of Channel State Information (CSI) from all the users. In MU-MIMO based WLANs, the number of CSI request increases with the number of users. This results in an increased CSI overhead and in degradation of the overall throughput. Most of the proposals in the literature have not addressed the contention in the CSI feedback clearly. Hence, in this paper a Joint User Selection and Scheduling (JUSS) scheme is discussed and its performance is evaluated in terms of throughput, delay, packet loss and fairness. In the performance comparison some wellknown Medium Access Control (MAC) protocols are considered. The proposed scheme not only enhances throughput, but also avoids contention during CSI feedback period.

Opis:
In this research, the carbon particle dispersions are made in two different levels as carbon nano tube (CNT) and carbon particle in microns range. The mechanical strength is evaluated for the composites developed by axial loading and bending test analysis. In addition, the air jet abrasive particle erosion study is performed for different angle of impingement. The dispersion of carbon particle in the matrix material has reduced the mechanical strength. The sample with 4% of CNT dispersion in the composite has a maximum strength of 143 MPa and a minimum strength of 112 MPa. For the same combination (4% of CNT composite), the maximum flexural strength is 116 MPa. It is clear to infer that the strength of CNT in matrix materials is superior to the increase in length of carbon particle. The dispersion of carbon particle in the matrix material increases the brittleness and the strength is diminished. During the flexural bending, the fiber delamination occurred with severe deformation in the plain composite. When the materials are subjected to impingement of solid particle, the attrition effect on the exposed surfaces is vulnerable towards erosive mechanism. The presence of carbon in the matrix material has significantly increased the surface property. The results are appreciable for 4% of CNT composite. Especially at 30º, the minimum erosive wear 0.0033 g/g has been recorded. Erosive wear is less at minimum impingement angle and the wear is found increasing at higher impingement angle. Therefore, it is recommended not to add carbon particle to a higher weight percentage, since it leads to brittleness.

Urban areas and metros are growing at a much higher rate than the rural areas. Urban areas play a significant role in the development of the nation by contributing 60% of the national income with only 27.78% of the population. Urban Transport is the most crucial (infrastructure) element in shaping urban development and living. The supply of transport is heterogeneous with a number of interacting and competing modes while the demand for it is derived from the overall pattern of urban activity. Urban Transport has a significant impact on the environment, land use, and land development patterns. In India, multiple institutions are responsible for urban transport and it is governed by multiple policies/ Acts/ legislations. While bus is the major mode of urban transport, local/suburban trains (Railway), Taxies/Autos and personalized transport makeup the rest. Lack of proper public transport has resulted in the increase of personal vehicles, causing problems of congestion, pollution and loss of productive time on travel delays. Study of urban transport systems across the world has revealed that well coordinated institutions with dedicated funding sources and proper planning ensure well functioning urban public transport systems, keeping the cities liveable and productive. Urban transport has to be a public good and be funded through public resources. Indian context have revealed a good beginning made in this direction but absence of institutional arrangements for planning at local level, lack of coordination among various institutions and departments, lack of dedicated funding, lack of inter modal coordination, lack of patronage for new rail based systems are also glaring.

Opis:
Water and ethylene glycol as ordinary coolants have been broadly utilized as a part of a car radiator for a long time. These heat exchange liquids offer low thermal conductivity. With the progression of nanotechnology, the new era of heat transfer fluids called, “nanofluids” have been developed and analysts found that these liquids offer higher thermal conductivity contrasted with that of routine coolants. This study concentrated on the utilization of a mixture of water and ethylene glycol based Al2O3 nanofluids in a cooling framework. Pertinent information, nanofluid properties and exact connections were obtained from literature review to examine the performance of a twin cylinder Diesel engine under various blends of nanofluid based coolants, furthermore, to research heat exchange improvement of a car radiator worked with nanofluid-based coolants. It was observed that, the performance of Diesel engine and heat transfer rate in cooling system framework enhanced with the utilization of nanofluids (with water and ethylene glycol the basefluid) contrasted with water and ethylene glycol (i.e. base liquid) alone. In the wake of leading the series of tests on Twin cylinder Diesel engine at 2%, 1% and 0.5% of nanofluid in basefluid, it was observed that performance of Diesel engine and heat exchange is upgraded better at 0.5% of Al2O3 nanofluid coolant.

Opis:
Hepatoprotective and antioxidant activity of Lannea coromandelica bark extract (LCBE) was investigated on thioacetamide induced hepatotoxicity in rats. Hepatotoxicity was induced by thioacetamide (TAA) administration (100 mg/kg. s.c). LCBE at different doses (400 and 200 mg/kg) were administered orally to male wistar rats. Thioacetamide caused elevation of serum concentration of AST, ALT, ALP, serum bilirubin and also reduced serum concentration of total protein, albumin, sodium, potassium in animals as compared to control (p < 0.05) but LCBE treated rats showed maximum reduction of AST [(138±5.1) IU/L], ALT [(71 ±2.7) IU/L], ALP [(140 ±1.9) IU/L] with the high dose (400 mg/kg bw) of combined aqueous and alcoholic bark extract. Whereas, serum bilurubin, cholesterol, sugar and LDH content were varied with the treatments but showed higher with the only ethanolic extract at dose of 400 mg/kg. The IC50 value was observed as (83.28 ±2.12) μg/mL, for DPPH radical scavenging activity. Result concluded that ethanolic extract and combined aqueous and alcoholic bark extract of L. coromandelica showed a potential hepatoprotective and antioxidant activities might be due to the presence of phenolic groups, terpenoids and alkaloids.
