The cores of electrical machines are generally punched and laminated to reduce the eddy current losses. These manufacturing processes such as punching and cutting deform the electrical sheets and deteriorate its magnetic properties. Burrs are formed due to plastic deformation of electrical sheets. Burr formed due to punching on the edges of laminated sheets impairs the insulation of adjacent sh...

This study investigates the effects of two different catalytic activation techniques on the thermal performance of the flip-chip heat spreaders. The two activation techniques studied are thin nickel–copper strike and galvanic initiation. Thermal diffusivity and surface roughness of these heat spreaders were studied using the Nano-flash Apparatus and Infinite Focus Microscopy. High temperature s...

Recent advances in biomedical sensors, data acquisition techniques, microelectronics and wireless communication systems opened up the use of wearable technology for ehealth monitoring. We introduce a galvanic coupled intrabody communication for monitoring human body hydration. Studies in hydration provide the information necessary for understanding the desired fluid levels for optimal performan...

the objective of this study was to describe the role of electrical stimulation in controlling peripheral vertigo. in a prospective study on 13 healthy volunteers, nystagmus was induced with caloric stimulation and the interval of nystagmus disappearance was recorded. this time indicates the basal response of vestibular end-organ. after caloric irrigation, pulsed signal was applied for each pers...

introduction to extract and combine information from different modalities, fusion techniques are commonly applied to promote system performance. in this study, we aimed to examine the effectiveness of fusion techniques in emotion recognition. materials and methods electrocardiogram (ecg) and galvanic skin responses (gsr) of 11 healthy female students (mean age: 22.73±1.68 years) were collected ...

A first 352 Mhz CH-cavity is under construction, which will demonstrate main production steps like stem welding and galvanic copper palting of the completed stainless steel tank module

In this paper, two kinds of micro-arc oxidation (MAO) coatings on TA2 with different thickness were prepared by controlled time and then characterized for their composition, crystalline structure, surface morphology. The effect MAO treatment electrochemical corrosion behaviors in 3.5% NaCl solution studied the measurements including open circuit potential (OCP), impedance spectroscopy (EIS) pot...

G replacement reactions between solid metal nanoparticles with oxidizing metal precursors represent a versatile strategy for synthesizing hollow metal nanostructures with tailored properties that are difficult (or even impossible) to achieve from their solid counterparts. For example, reactions of silver nanocubes with aqueous solutions of HAuCl4 enable the synthesis of hollow nanoboxes with se...
