VIBRATION ANALYSIS OF A ROTATING TAPERED COMPOSITE BEAM WITH TIP MASS
In this study, free vibration responses of a rotating tapered composite beam with tip mass are investigated. The energy expressions for the kinetic and potential energies of a rotating composite beam with tip mass have been formulated. The energy expressions are then applied in Lagrange’s equations to develop the equation of motion of a composite beam with tip mass. The stiffness and mass matrices for a standard composite beam element with two end nodes with two degrees of freedom at each node are derived. Various parametric studies are performed to investigate the effect of tip mass and the rotational speed on the variation of natural frequencies of the composite beam. The investigations are also done to study the effect of hub radius on the natural frequencies. It is shown that the addition of tip mass increases the stiffness of the structure and consequently increases the natural frequencies
GDP-An Accountable Data Transfer Across Multiple Entities
We propose a novel answer for cross-site cold-start item suggestion, which intends to we show a nonspecific information genealogy structure GDP(Generic Data Protection) for information stream over different elements that take two trademark, main parts (i.e., proprietor and buyer). We characterize the correct security ensures required by such an information heredity system toward distinguishing proof of a liable substance, and recognize the streamlining non-denial and genuineness suppositions. We at that point create and break down a novel responsible information exchange convention between two elements inside a pernicious situation by expanding upon unmindful exchange, vigorous watermarking, and mark primitives. At long last, we play out a trial assessment to exhibit the common sense of our convention and apply our system to the vital information spillage situations of information outsourcing and interpersonal organizations
Design and Synthesis of Some New Quinoline Based 1,2,3-Triazoles as Antimicrobial and Antimalarial Agents
A series of novel 6-bromo-2-chloro-3-(4-phenyl-[1,2,3]triazol-1-ylmethyl)-quinoline and its derivatives (5a-j) were synthesized in good yields from the intermediates (6-bromo-2-chloro-quinolin-3-yl)-methanol (2), methanesulfonic acid (6-bromo-2-chloroquinolin-3-yl)methyl methanesulfonate (3) and 3-azidomethyl-6-bromo-2-chloro-quinoline (4). The synthetic route leading to the title compounds is commenced from commercially available 6-bromo-2-chloro-quinolin-3-carbaldehyde (1). The chemical structures of the newly synthesized compounds were elucidated by their IR, 1H and 13C NMR, mass spectral data and elemental analysis. Further, all the target compounds were screened for their antimicrobial activity against various microorganisms and antimalarial activity towards P. falciparum.

Polyethylene glycol (PEG-400) as a medium for novel and efficient synthesis of 2-phenyl-2,3-dihydroquinazolin-4(1H)-one derivatives
A novel, efficient synthesis of 2-phenyl-2, 3-dihydroquinazolin-4(1H)-one derivatives is reported for the first time in PEG-400 by the reaction of various aldehydes, anthranilamide under catalyst-free conditions and the formation of product good to excellent yields. PEG-400 can be recovered and reused without any significant loss of activity
