Compactness and light weight, large exit pupil diameter distance, small distortion for virtual image, see-through paths are pivotal factors to achieve a better, wearable experience of optical head-mounted displays (OST-HMDs). In addition, efficiency the image path is an important factor heat dissipation in HMD devices. This paper presents new type OST-HMD system that includes three wedge-shaped freeform prisms two symmetric lenses. Based on 0.71 in. microdisplay, prototype with diagonal...
Jiayuguan, the first majestic pass at western end of Ming Dynasty's Great Wall, is an important world cultural heritage site with high historical, scientific, social, and artistic value. It primarily constructed rammed earth has existed in form relics for over 600 years. Due to prolonged exposure natural environmental factors such as rainfall, wind-borne sand, temperature variations, typical crack diseases have developed significantly, posing a threat overall stability earthen site. To...
This study aims to investigate the heat and thermal insulation mechanisms of aerogel heat-insulating reflective coatings. Two working conditions, hot box method open environment at end, were simulated using a gypsum board as substrate. We conducted tests on blank panels, composite panels with coatings, XPS-insulated for two operating conditions. And power calculation was carried out barrier materials. The test results show that air temperature differences between cold ends blank, coating,...
The influence of temperature on the dynamical read performance tags is presented in this paper. A RFID detection system including a control devised to simulate dynamic reading UHF system. distance tag measured at different temperature. result shows that reduces with increase test This paper provides an effective method for selection and evaluation
The impact–echo method is a superior for detecting the health of concrete structures, but it has disadvantage significant errors when identifying structural boundaries. In order to overcome this limitation, paper proposes calculation using cross-sectional vibration mode in combination with detect columns. variation predominant frequency mid-column region and critical boundary studied. influence edge on detection results analyzed. differences eigenvalues under different cross-section modes...
Shrinkage differentiation and the need for multiple replenishments of slurry after fissure reinforcement are key problems grouting fissures in earthen sites. In this study, quicklime was mixed with 1.5% SH binder, clay, fly ash different proportions to prepare nine mixtures water-cement ratios SH-(CaO + C F) slurry. An expansibility test performed, based on results, four groups were selected a fluidity test. Ultimately, three considered, mixing ratio 3 : 2 5 determined produce optimum The...
This paper presents the combination diagnosis method based on genetic algorithm for rotating machinery according to limitation that any single fault feature or can not achieve accurate result in whole state space. effectively use all kinds of different characteristic features and methods then bring into play their advantage, so rate is improved. combines neural network with artificial immune using features. Then each displays its advantage optimal Wavelet Packet "energy" Bispectrum are used...
Although the fully grouted tension anchorage system (T-anchorage system) has been widely used in field of anchoring earthen heritage sites, it always suffered from failure bolt–slurry interface debonding and strong attenuation shear stress along embedment length. In this article, a new type tension–compression composite (TC-anchorage is proposed, which made up pressure bearing with same diameter anchor hole at end bolt. The situ anchorage, pull-out test interfacial stress–strain monitoring...
Fully grouted anchor systems have been widely used for stability control at earthen sites. The bond performance between the bolt and slurry, which is determined from type, diameter, slurry thickness length, has an important influence on working mechanism of system. This paper considers three consisting different types bolts modified glutinous rice slurry. To test relevant physical mechanical indexes soil a site, bolts, in situ anchor, pull-out tests stress–strain monitoring bolt–slurry...
The peeling disease has caused the volume of earthen site to recede over years, seriously jeopardizing longevity sites. Accurately evaluating degree development is key carrying out conservation work. This paper organically combines Decision Making Trial and Evaluation Laboratory, multi-correlation coefficient, anti-entropy weight method in a weighted average combination, assigns weights indicators rank sum ratio method. improved RSR evaluation comprehensively, objectively, accurately...
