Based on the electromagnetic induction heating method, and curing of Carbon Fiber Reinforced Polymer (CFRP) have advantages high energy utilization no pollution. However, in process, both material weaving structure mold can affect temperature field. Therefore, this study, an finite element analysis model for CFRP circular tubes was established based equivalent thermal characteristics CFRP. The ...

This paper shows how to reduce the temperature dependence of a temporary optical coupler that enables us output signal light from bent fiber by aligning probe in path leaked and input fiber. We experimentally demonstrate coupling efficiency between fibers is significantly improved reducing misalignment these created changes. First, we confirm comparing calculation results measured values conven...

• A transmission line model with Warburg impedance is needed to fit the spectra. The electrical resistance of fibers governs high frequency 45° line. increases yarn length. Performance engineering electrochemical energy-storage devices such as Supercapacitors (SCs) requires updated modeling capable characterizing their output in unique device geometries. In this work, an Equivalent Electrical C...

Interferometric fiber-optic gyroscopes (IFOGs) are widely utilized due to their compact size and solid-state design. However, sensitivity of detecting rotation is limited by the relative intensity noise (RIN) associated with broadband source. To overcome this limitation, a conventional fiber ring resonator (FRR) can be employed filter RIN specifically at IFOG frequency. Nonetheless, implementin...

To design more effective tissue-engineered heart valve replacements, the replacement tissue may need to mimic the biaxial stress-strain behavior of native heart valve tissue. This study characterized the planar biaxial properties of tissue-engineered valve leaflets and native aortic valve leaflets. Fibrin-based valve equivalent (VE) and porcine aortic valve (PAV) leaflets were subjected to incr...

Although the importance of the nucleus raphe magnus in descending inhibitory control of nociception is clear, it is not known whether these effects are equivalent for different types of nociception. Thus, we examined the differential inhibition of behavioral responses evoked by A or C fiber thermonociceptor activation by electrical stimulation of nucleus raphe magnus neurons as well as the invo...

Longitudinal impedance of skinned muscle fibers was measured with extracellular electrodes and an oil gap method in which a central longitudinal section of fiber is insulated by oil while the ends of the fiber are bathed in conducting pools of relaxing solution. Intact single fibers were isolated from frog semitendinosus muscle and the sarcolemma removed either by mechanical or chemical methods...

Abstract This paper describes a method for aligning stiff, high-aspect-ratio microcrystals over macro-length scales using polymer fiber drawing process. A composite preform was constructed with an interfacial, liquid shell layer of grapeseed oil suspending ytterbium-doped potassium lutetium fluoride (30% Yb:K 2 LuF 5 , KLF) between adjacent cylindrical surfaces acrylic (polymethyl methacrylate,...

In this work, a series of numerical simulations are formulated for studying the performance (collection efficiency and pressure drop) of filter media with bimodal diameter distributions. While there are numerous analytical expressions available for predicting performance of filters made up of fibers with a unimodal fiber diameter distribution, there are practically no simple relations for bimod...
