The cyclic loading performance of bamboo double-jointed components different column base connection types was investigated through reversed tests and finite element analysis. Test results indicated that the connections played an important role in failure modes engineered columns: for encased steel plate connection, main mode tensile fracture scrimber section at bottom cladding plate; a slotted-...

OBJECTIVE Anterior cervical discectomy and fusion (ACDF) is often complicated by subsidence, pseudoarthrosis, kyphosis, and graft donor site morbidities. To decrease the occurrence of these complications, various types of cages have been developed. We designed this retrospective study to analyze and compare the efficacy and outcomes of ACDF using double cylindrical cages (DCC) (BK Medical, Seou...

The paper addresses the active control of the sound transmission through a double panel partition. A literature survey indicates that active cavity control is much more efficient than active structural control. The vibro-acoustic behaviour of the double wall is analysed in light of this observation. This analysis shows that the sound transmission through the double panel is larger than that thr...

OBJECTIVES To retrospectively evaluate stabilisation of long-bone fractures in cats and small dogs using the Unilock system. METHODS Medical histories and radiographs of consecutive patients with long-bone fractures stabilised with the Unilock system were reviewed. Cases with follow-up radiographs taken at least four weeks postoperatively were included. Signalment of the patient, fracture loc...

A rectangular isotropic two-layer plate of an irregular structure is considered, the edges which are freely supported, and a constant temperature maintained on them. Two-dimensional Kirchhoff-type thermoelasticity equations two-dimensional heat written for inhomogeneous material were used to study stresses in plate. Using method double trigonometric series spatial variables Laplace integral tra...

Partial discharge (PD) localization is critical to ensure the safe operation of power equipment. In this paper, an optimization scheme developed for PD positioning external insulation The based on eight-element cross sensor array receive ultrasonic signal generated by PD, and uses highly accurate 2-D multiple classification (2-D MUSIC) algorithm locate signal. Simulated adopted test scheme, res...

let  be a banach algebra. let  be linear mappings on . first we demonstrate a theorem concerning the continuity of double derivations; especially that all of -double derivations are continuous on semi-simple banach algebras, in certain case. afterwards we define a new vocabulary called “-higher double derivation” and present a relation between this subject and derivations and finally give some ...

The performance of a new kind of double gap resistive plate counter (RPC) has been studied using cosmic rays. The detector was operated with a mixture containing low percentage of isobutane. A comparison with the behaviour of RPC flowed with standard mixture is presented.

natural vibration analysis of plates represents an important issue in engineering applications. in this paper, a new and simplify method for vibration analysis of circular and rectangular plates is presented. the design of an effective robust controller, which consistently attenuates transverse vibration of the plate caused by an external disturbance force, is given. the dynamics of the plate i...
