The modern GNSS technique is one of the most effective geoscience and remote-sensing tool to observe crustal motions quantify plate tectonics dynamics. Given multiple installed continuously operating observing stations, multi-frame transformation implemented connect timevarying coordinates by traditional step-wise method. Compared with treatment each pair frames, proposed structured total least-squares method considers combined estimation for all guaranteeing unique consistent results...
In real estate valuation using the Hedonic Price Model (HPM) estimated via Ordinary Least Squares (OLS) regression, subjectivity and measurement errors in independent variables violate Gauss–Markov theorem assumption of a non-random coefficient matrix, leading to biased parameter estimates incorrect precision assessments. this contribution, Errors-in-Variables model equipped with Total (TLS) estimation is proposed address these issues. It fully considers random both dependent variables. An...
Abstract Polyethylene glycol (PEG) is a widely available and environmentally friendly phase change material known for its high energy storage capacity. However, application in various industries limited due to slow heat absorption release, poor mechanical properties, inadequate weather resistance. PEG was blended with waterborne epoxy resin (WER) improve properties Furthermore, graphene nanoplatelets (GNPs) boron nitride (BN) were incorporated into the WER/PEG substrate prepare...
The reliability theory has been an important element of the classical geodetic adjustment and methods in a linear Gauss-Markov model since Baarda invented 1968. Although widely investigated applied to variety geodetic, photogrammetric, remote sensing problems, there is no report theoretical progress improve further Baarda's measures among models. We propose power effect minimum detectable outlier on parameters as alternative external measure, present regularized reliability, demonstrate for...
Cellular composite, with an array of regular hexagonal cells in the cross section, is a type textile composites having advantage being light weight and energy absorbent over solid composite materials. However, when it under same level low velocity impact different tup mass velocity, its behavior yet unknown. In experiment, four groups samples, twelve geometrical variants have been systematically created for testing. The test running two categories one initial 5.5 m/s by 0.55 kg, another...
In this paper, by combining the structures of epoxy and benzoxazine, we report a method preparing multifunctional resins without decreasing overall number functionality. Herein, phosphorus-containing benzoxazine (1) with hydroxyl linkage was designed. Based on (1), series advanced (2) various phosphorus contents were prepared nucleophilic addition phenolic OH oxirane CNE. addition, effect reaction conditions preparation monitored EEW titration NMR analysis. our study, although functionality...
In this article, the deficiencies of traditional methods project cost control have been objectively analyzed. Through applying process project, establishing method management information systems and combining practices, system model dynamic has explained.
With the continuous improvement of China’s construction technology, application mass concrete structures is increasingly popular in various order to meet requirements structure and function, such as tall buildings, dams, railways highways. There are all kinds cracks process because big cross section. many reasons form cracks, but temperature most common cause. It vital quality that hydration heat, especially peak value rise, calculated advance precautions implement accordingly. In this...
Although the least squares (LS) fitting of circle has been widely known in measurement, weighted LS is not thoroughly investigated, particular, when prior weight information only partly known. Based on Gauss-Helmert model (GHM), we first investigate invariance translation and rotation. The results show that though translational holds, rotation broken except for some specific structures. As main finding this paper, develop VCE theory directly adapting to nonlinear GHM representation problem...
