Joined-wing aircraft are being designed for ‘sensorcraft’ configuration. Joined wings lead to multiple load paths and constraints. The focus of this work is to understand the nonlinear structural as well as aeroelastic behavior of joined wings. The paper presents a formulation for the nonlinear aeroelastic analysis of joined wings. Results are presented for two joined wings configurations. Over...

Excessive vibration can be detrimental to the structural integrity of structures or can adversely affect the performance of instruments such as telescopes or antennas. One field in Structural Dynamics is the design and application of systems that reduce the amplitude and duration of vibration. There are two types of vibration suppression systems: passive and active. Passive means that the dampi...

in this report, we describe a procedure for in-silico design of a novel haloalkane dehalogenase protein that exhibits luciferase property which can be potentially used in biosensor applications. from a pdb blast search, the selected haloalkane dehalogenase (pdb code: 1ede) had a close structural homology with a lucifearse (pdb code: 2psj chain a) sharing an identity of 33%. initially, the amino...

The concept of business banking relationship, ie, the relations between banks and their client firms, as found in literature, is a poor conceptualisation of a rich and complex phenomenon whose structural, dynamic and organisational aspects are thus neglected. Most studies stress the operative and administrative issues whilst others looked at the relationships between banks and their customers a...

In this literature, the symmetric inverse generalized eigenvalue problem with submatrix constraints and its corresponding optimal approximation problem are studied. A necessary and sufficient condition for solvability is derived, and when solvable, the general solutions are presented.

At the territories of three key sites with different environmental conditions (coast of Irkutsk Reservoir, the Goloustnaya River basin, surroundings of Gakhany settlement in 60 km northward from the urbanized area Ust’-Orda, Irkutsk Region), we performed studies aimed to reveal the structural-dynamic organization and trends of forests reconstitution at the places of burnt areas and of cuttings ...
