Combined experimental and computational analysis of hygrothermal performance of an interior thermal insulation system applied on a brick wall is presented in the paper. In the experimental part, the functionality of the insulation system is tested at simulated difference climate conditions using a semi-scale device. The measured temperature and relative humidity profiles are used for the calibr...

A patient is described in whom myopotentials orginating from the anterior abdominal wall muscle suppressed the implanted demand pacemaker despite its bipolar mode of action. This phenomenon was shown by simultaneous recording of the electrocardiogram the electromyogram. At operation, a defect in the insulation of a previously repaired epicardial electrode was found lying in close proximity to t...

In this study, we discuss about the energy saving in different type of building walls by using optimum insulation thickness with suitable insulation material. The energy saving is maintained by reducing the energy consumption in buildings. Heat losses from building envelope have a major share in waste of energy. So it is essential to save the energy by using optimum insulation thickness. The in...

Solid wall dwellings in the UK are urgent need for energy retrofit to support achieving net-zero strategies building sector and reduce fuel poverty. Several barriers a cause of uncertainty householders about Wall 1nsulation (SWI) slow down progress. This paper aims examine people's perceptions possible inclusion aesthetics elements Internal Insulation (IWI), providing suitable solution promote ...

This work introduces an economic solution for the problems of sound insulation of recording studios. Sound insulation at wall resonance frequency is weak. Instead of acoustical treatment, a digital filter is used to eliminate the effects of wall resonance and coincidence phenomena on recording of speech. Sound insulation of studio is measured to calculate the wall resonance frequency and the co...

The acoustic insulation provided by separating walls has been studied for many years, with the first publications dating from the early part of the 20th century [1]. Since then, different analytical and numerical models, for predicting the sound transmission via single and multi-panel walls, have been proposed. However, given the large number of variables of this problem and the uncertainties i...

Detailed simulations have indicated optimum insulation thicknesses of walls’ insulation for a variety of cases. Simplified analytical relations have also been proposed to the same aim, allowing the extraction of more general results, with limited accuracy however, as imposed by mathematical simplicity requirements. In this sense, a variety of important parameters are ignored, such as: the exist...

Here, we report a nanopipette-based electrochemical approach to prepare metal nanoelectrodes with excellent control over electrode size, shape, and thickness of the insulation wall. Nanoelectrodes are prepared by electrochemical plating in a laser-pulled quartz nanopipette tip immersed in a liquid gallium/indium alloy electrode, which not only protects the ultrasmall quartz tip but also starts ...

1 ABSTRACT With uncertainty of energy prices and an increased interest in sustainability, more builders and designers are striving for dramatic levels of home energy efficiency. Performance of the home’s envelope is clearly critical in this endeavor. In colder climates, several builders are moving towards whole-wall thermal resistances above 30 fthr°F/Btu (4.9 m°C/W). While there are numerous h...

oil and gas transmission pipelines are critical items of infrastructure in providing energy sources to regions and countries. steel pipes are commonly used which can be subject to both internal and external corrosion. this paper presents an advanced nondestructive inspection technique for detection of oil-gas pipeline corrosion defect. the pulsed eddy current (pec) method has been successfully ...
