Based on similarity theory, the systemic analysis for the distribution characteristics of tunnel temperature field in two different working conditions of having no thermal insulation and installing PU as insulator is progressed by using manufactured model test platform in order to realize the tunnel temperature field rule in cold regions with or without thermal insulation and the influence of thermal insulation layout pattern on insulating effect.

Energy consumption, specifically in the building sector, is expected to rise. One potential way to reduce energy consumption, or to slow this increase, is to reduce the heat loss in residential homes. Silica aerogels have grown in popularity as an insulating material due to their extremely low thermal conductivity. However, the benefits of using silica aerogels as an insulator in residential buildings have not been thoroughly studied. To understand the benefits of using silica aerogels as a thermal insulator in residential homes, experimentally validated simulations were performed. The simulat

This paper deals with the electrical insulation of a gap bridged by a solid dielectric between a pair of electrodes in a vacuum, where the dielectric is a model of an insulating spacer holding electrodes in various vacuum devices. Such gap configuration is typical as a model for studying physical mechanisms of an electrical breakdown or a flashover in a vacuum, in which the insulation ability is considerably lower than a gap without any insulating spacers. Many researchers have long investigated the mechanisms of flashover, and it is believed that the charging of the insulator surface is the p

Abstract:
Utilization of a transparent insulation material (TIM) in a solar collector wall has been proven to have a significant potential to reduce heating load in passive solar buildings. Transparent insulation transmits a high proportion of incident solar radiation onto a layer of thermal mass which subsequently slowly releases heat, thus reduces the requirement for heating throughout the day. Due to the high transmittance and convective suppression properties of the transparent material, the thermal resistance of the wall will be improved extensively with minimum losses of transmitted radiation.

A consequence of insulating the equipment is the necessity to manage the introduced threat of corrosion under insulation (CUI).

Abstract:
The purpose of this paper is to discuss electrical leakage in the insulating material of typical platinum resistance thermometers (PRTs) and how it can be modeled to understand its effect on PRT measurement. The paper will present comprehensive background information regarding PRT insulation leakage, what it is, how it is caused, and how it affects PRT measurement. To model the effect on PRT measurement, the insulating materials and sensor circuit in a typical PRT are transformed into an equivalent electrical circuit that is analyzed using SPICE circuit analysis.

Abstract:
Frozen soil foundations are prone to frost heave and thawing under freeze-thaw cycles, which can cause substantial damage to road structures in permafrost areas. The performance of the thermal insulation of the foamed mixture soil subgrade of the S301 highway in Xinjiang was examined as a case study, and the temporal and spatial variation in temperature and strain of the foamed mixture soil subgrade analyzed and compared with those of the original gravel subgrade. The results show that (1) the thermal insulation performance of the foamed mixture soil subgrade is excellent, temperatures tend to

Abstract:
This study assesses the interaction between climate change and agricultural trade policies. We distinguish between two dimensions of agricultural trade policy: market insulation and subsidy levels. Building on the previous work of Tsigas, Frisvold and Kuhn (1997) we find that, in the presence of current levels of agricultural subsidies, increased price transmission --as called for under the Uruguay Round Agreement on Agriculture-- reduces global welfare in the wake of climate change. This is due to the positive correlation between productivity changes and current levels of agricultural support

Abstract:
To reduce CO2 emissions and save grey energy, natural materials like wood and wooden materials are becoming more and more important. However, these products are particularly sensitive to moisture, as they can be attacked by mould or decay fungi. In contrast to mould growth, which typically is associated with visual impairment and health problems, the growth of decay fungi may result in structural defects which clearly must be excluded. Up to now it is mostly assumed that wooden materials are more sensitive to such attack than solid wood. Therefore, different wood fibre insulation materials wer

Abstract:
Electric and natural gas utilities often find it advantageous to share rights-of-way. Available methods for evaluating electrical effects on gas pipelines have been difficult to use at best, and at worst, incorrect. A generalized approach that addresses inductive and conductive interferences has not been available. Initiated to fill that need, this work is part of a research effort cosponsored by EPRI and the Pipe Line Research Council International, Inc.

Full text
Abstract:
Natural gas meters are often used to measure flows below their minimum design flow rate. This can occur because of inaccurate flow projections, widely varying flow rates in the line, a lack of personnel available to change orifice plates, and other causes. The use of meters outside their design ranges can result in significant measurement errors. The objectives of this project were to examine parameters that contribute to measurement error at flow rates below 10% of a meters capacity, determine the expected range of error at these flow rates, and establish methods to reduce measurement error i

Abstract:
- To understand contemporary challenges to European democracy, it is crucial to look beyond the surface of politics and consider the deeper relationship between democracy and the economy. Instead of focusing exclusively on the rise of ‘populism’, it is necessary to acknowledge the multiplicity of threats to European democracy, in particular those arising from the structure of European economies and economic policymaking. - Understanding these weaknesses in the functioning of European democracies is crucial to an effective approach to future economic transformations, in particular the green tra

Abstract:
Noise levels radiated from the exterior of a pipe wall can significantly contribute to the overall noise levels on the site of a gas plant and at neighboring properties. The noise inside the piping is generated both by the gas compressor itself, and by the flow of gas through valves, elbows and fittings. Sound inside the pipe couples to the pipe wall by exciting vibration modes, some of which are radiated from the exterior of the pipe into the air. Piping is geometrically circular, which provides it with considerable increased stiffness versus a flat plate, and thereby assists in its ability t

Abstract:
This study aims to investigate the effects of various parameters including the height of the profiling region, spacing of profiling ribs, length of the panel, thickness and modulus of the foam core, and thickness of the profiled face sheet, on the local buckling capacity of profiled metal faced insulating sandwich panels. A simplified finite element (FE) modeling approach that models the profiled face sheet as a folded plate structure resting on elastic foundation is adopted. This modeling approach was validated through comparison with tests results and 3D FE modeling of the entire sandwich st

Abstract:
Widely employed in enveloped structures, the metal-faced sandwich panel boasts thermal insulation, noise abatement, lightweight, and remarkable assembly efficiency. In this paper, a new type of profiled steel sheet and polyurethane sandwich slab (PSSPSS) was proposed. Through static load tests and numerical simulations, the flexural properties of the PSSPSS were studied, and the influence of individual geometric parameters on the flexural capacity of the structure was evaluated. The results of this analysis led to the derivation of the calculation formulas for the deflection and flexural beari
