abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...

For the purpose of splicing widening bridges without interrupting traffic in expressway reconstruction and extension projects, different types anti-differential disturbance concrete (ADC) were developed. This paper experimentally investigated mechanical performance ADC under influence traffic–vehicle coupling vibration. The experimental device, with one end fixed other vertically vibrated, was ...

the vibration of cable-stayed bridges subjected to the passage of high-speed trains is studied in this article. the moving train includes a number of wagons, each of which is modeled as a four-axle system possessing 48 degrees of freedom. the car model is nonlinear and three-dimensional and includes nonlinear springs and dampers of primary and secondary suspensions, dry friction between differe...

Externally bonding steel plates is a common method for strengthening old bridges. Structural features and diseases of T-beam bridge are described. The project Erdao River Bridge was taken as an example. Based on static load test, changes deflection stress studied at the bottom RC T-beams strengthened by externally in loading process. Numerical simulation also carried out. results test show that...

Abstract In this paper, we study a plate equation as model for suspension bridge with time-varying delay and weights. Under some conditions on the weight functions, establish stability result associated energy functional. The present work extends generalizes similar results in case of wave or equations.

The orthotropic steel deck is sensitive to fatigue, and a number of cracks have been found in existing bridges. Based on the long-span Guangzhou Mingzhu Bay arched bridge, this paper focus cracking process, fatigue mechanism, performance evaluation an bridge under traffic load. A finite element model three-U-rib three-span was first established investigate stress state most unfavorable wheel lo...

In this paper, an analytical method is proposed for the modeling of electromagnetic energy harvesters (EMEH) with planar arrays permanent magnets. It shown that can accurately simulate generation electrical power in EMEH from vibration a bridge subjected to traffic loading. The consists two parallel 5 by small cubic magnets (PMs) are firmly attached solid aluminum base plate, and thick rectangu...

This paper reports on electric field measurements, using the field-induced second harmonic (E-FISH) method, sampling spatial structure and temporal development of DC-driven positive streamer coronas in atmospheric-pressure air at relevant timescales to examine self-pulsating behavior discharge. The discharge is triggered from a point-to-plate geometry consists transient coronas, which bridge in...

The objective of this work was to monitor the consolidation of the femur after osteosynthesis with a bridge plate associated with the intramedullary pin using scintigraphy. We used seven New Zealand breed male rabbits, at 4 months of age, with a mean weight of 3.5 kg. We performed a three-phase bone scintigraphy with technetium-labeled methylene diphosphonate (99mTc-MDP) before and after surger...

Bridge expansion joints (BEJs) are equipped at the girder end of long-span railway bridges to ensure reliable transition track. BEJs should have suitable dynamic stiffness running safety and stability vehicle. To explore influence vertical on response vehicle, track, bridge, a three-dimensional vehicle-track-bridge coupled model is established, sleeper spacing vehicle speed taken into considera...
