Authors : Vishva Joshi, Umang Thakkar

Cloud computing is the pool of the heterogeneous resources aim to achieve maximum resource utilization to users with higher availability at minimized cost. Now, a days demand of cloud resources are increases and demand is change day by day. So, to solve the problem of resource utilization required the load balancing, scale- up, scale-down of the resources as per requirement of cloud service users. And for scaling decision there are need check CPU utilization and current requests of users then gives the prediction decision to scale up and scale down scenario.

Hyperspectral data, spectrum mixture, Linear-Nonlinear spectral mixture, Linear-Nonlinear Model, PCA

Authors : Vidhi Joshi, Ritika Lohiya, Shailendra Shrivastava

Hyperspectral imaging is a continuously growing area of remote sensing application. Hyperspectral data is often used to determine what materials are present in a scene. Materials of interest could include roadways, vegetation, and specific targets (i.e. minerals, manmade materials etc.). The AVIRIS-NG (Airborne Visible InfraRed Imaging Spectrometer – Next Generation) data set can be seen as a cube in which each pixel is given by the spectral signature of the underlying materials in that area of the image. The motivation of unmixing is to find a collection of pure spectral constituents. Some of the unmixing techniques are used as Linear Mixing Model (LMM) and Nonlinear Mixing Model. LMM assumes that endmember substances are sitting side-byside within the FOV. Nonlinear Mixture Model assumes that endmembers components are randomly distributed throughout the FOV with Multiple scattering effects. Hyperspectral unmixing is used in many practical applications, such as precision agriculture, monitoring and management of natural disaster, issues related to security, and defense. This paper is related to the basic concepts of hyperspectral unmixing and techniques respectively.

Low-Complexity wavelet Based Channel Estimation with low Leakage for OFDM Systems

Authors : Md Reshma, K.Thirupathi

In this paper, we describes, a low-complexity wavelet -based channel estimator with low leakage is proposed for OFDM systems using virtual subcarriers. In this paper, a new threshold based method using wavelet decomposition will be proposed which is based on an initial LS estimation technique. The reported simulation results show that the proposed method has better performance compared to the other methods such as Lee Method that has been published recently.. The performance and complexity of the proposed channel estimator are analyzed and verified by computer simulation. Simulation results show that the proposed estimator outperforms conventional estimators and provides near-optimal performance while keeping the low complexity comparable to the simple wavelet based channel estimator.

CHARACTERIZATION OF COMPOSITE MATERIAL (CLADDING OF COPPER-ALUMINIUM)

Authors : KODEM SURESH, DR.J.GOVARDHAN

Material obtained by combining two or more materials with various properties by metal working and fastening techniques such as riveting or by using nuts and bolts or by machining is called a composite. The entire work was performed to prepare a composite and to achieve its mechanical and metallurgical properties. The preliminary work was to make using pure Al and pure Cu work pieces where the metal pieces were rolled till a 10% reduction in thickness were obtained. Later Cu roll was sandwiched between Al pieces on either sides and rolling has been performed, thus a composite material with same metals on either sides and other metal in between has been made. The reason for sandwiching Cu in Al on either side is that on exposure to environment, the atmospheric oxygen and other gases reacts with the outer metal and forms oxide. Since Al is on the surface, it forms aluminium oxide which is non-reactive and acts as a protective layer to the inner metal. Thus Al works like a sacrificial anode. The purpose of making such a cladding is that, these types of cladded composites have wide range of applications. It is used for aerospace applications for fighter planes and satellites, used in submarines as the ship body has to be protected from the salt water and corrosive atmosphere. The Al on the outer surface continuously reacts with the salt and forms aluminium oxide which protects the inner Cu metal from getting oxidized and consumed. This type of composite has a wide range of application in defence for designing crucial components that get exposed to atmosphere. The advantages of using a composite material instead of a metal piece alone are that a composite material reduces weight as two or more different metals of different physical properties are being used. Composite material increases the mechanical and metallurgical properties of the work.

A STUDY ON COMBINATION OF STEEL AND GLASS FIBERS AS HYBRID FIBERS IN CONCRETE

Authors : N.N.Pavan Kumar, T.Raja Shekar, P.Tejeswar Kumar

Concrete is a brittle material when subjected to normal stresses and impact loads, where tensile strength is relatively low compared to compressive strength. This can be improved by addition of fibrous material. The geometric size and modulus of fibers are the main factors influence the mechanical performance of fiber reinforced concrete. The use of different type of fibers in a suitable combination may potentially improve the overall mechanical performance of concrete and increase tensile strength, energy absorption capacity of concrete. The present investigation studies the synergic mechanical properties of hybrid fiber polymer reinforced concrete. The properties of plain concrete, mono steel fiber concrete, glass fiber concrete and hybrid fiber concrete of M20 grade were studied and the properties of hybrid fiber concrete are compared with respect to plain and mono steel fiber and glass fiber concrete. Similarly the axial stress-strain curves under Axial Compression are studied.
