Experimental Studies of Stiffened Struc- Tures

چکیده
It is common to use sound insulation as a last resort for noise control in an urban city. Sound insulation of air-conditioned building is of importance. The stiffeners have important effects on the sound insulation properties of a stiffened structure. The experimental studies on the stiffened structures are vital for the study of the stiffener effects. Based on this concern, a simple stiffened plate system is designed which can be conveniently used in the experimental studies to investigate the effects of the stiffeners, such as the effects of the stiffener number, different stiffener locations and different stiffener materials. Experiments are carried out on this system. The results show that the properties of the stiffener, such as the stiffener positions, indeed have significant effects on the structural responses. The effectiveness of the designed stiffened system is also demonstrated.

Product of derivations on C$^*$-algebras
Let $mathfrak{A}$ be an algebra. A linear mapping $delta:mathfrak{A}tomathfrak{A}$ is called a textit{derivation} if $delta(ab)=delta(a)b+adelta(b)$ for each $a,binmathfrak{A}$. Given two derivations $delta$ and $delta'$ on a $C^*$-algebra $mathfrak A$, we prove that there exists a derivation $Delta$ on $mathfrak A$ such that $deltadelta'=Delta^2$ if and only if either $delta'=0$ or $delta=sdel...

متن کاملExperimental and Numerical Free Vibration Analysis of Hybrid Stiffened Fiber Metal Laminated Circular Cylindrical Shell
The modal testing has proven to be an effective and non-destructive test method for estimation of the dynamic stiffness and damping constant. The aim of the present paper is to investigate the modal response of stiffened Fiber Metal Laminated (FML) circular cylindrical shells using experimental and numerical techniques. For this purpose, three types of FML-stiffened shells are fabricated by a s...

A lot of recent work has studied strategies related to bulk loading of large data sets into multidimensional index structures In this paper we address the problem of bulk insertions into existing index struc tures with particular focus on R trees which are an important class of index structures used widely in commercial database systems We pro pose a new technique which as opposed to the curren...
متن کاملAutomatic rebuilding and optimization of crystallographic struc- tures in the PDB
Motivation: Macromolecular crystal structures in the Protein Data Bank (PDB) are a key source of structural insight into biological processes. These structures, some more than 30 years old, were constructed with methods of their era. With PDB_REDO we aim to automatically optimize these structures to better fit their corresponding experimental data, passing the benefits of new methods in crystal...
