Abstract:

Severe drought events have raised concerns regarding their effects on the phenological cycles of forest species. This study evaluates the correspondence between in situ phenophases and those detected by an unmanned aerial vehicle (UAV) in tree species coexisting within a mixed forest, with particular attention to their relationship with climatic variables. Based on 12 consecutive monthly field observations, we compared phenological developments with UAV-derived normalized difference vegetation index (NDVI) values, which were then correlated with environmental variables. The analysis revealed a

Abstract:

Summary The interplay of multiphase-flow effects and pressure/volume/temperature behavior encountered in reservoir simulations often provides strongly coupled nonlinear systems that are challenging to solve numerically. In a sequentially implicit method, many of the essential nonlinearities are associated with the transport equation, and convergence failure for the Newton solver is often caused by steps that pass inflection points and discontinuities in the fractional-flow functions. The industry-standard approach is to heuristically chop timesteps and/or dampen updates suggested by the Newton

Abstract:

The Lake Urmiah has undergone a drastic shrinkage in size over the past few decades. The initial intention of this paper is to present an approach for determining the so called “salient times” during which the trend of the shrinkage process is accelerated or decelerated. To find these salient times, a quasi_continuous curve was optimally fitted to the Topex altimetry data within the period 1998 to 2006. To find the salient points within this period of time, the points of inflections of the fitted curve is computed using a second derivative approach. The water volume was also computed using 16

The simplest equation of state compatible with the Widom and Griffiths scaling hypothesis have been built for the uniaxial ferroelectrics TGS and MAPCB. The explicit forms have been found of the scaling invariants deduced from the curves of the electric susceptibility measured in a constant biasing field. Smooth and sharp inflection points of the susceptibility curve in the vicinity of the critical temperature have been classified. The invariants and the inflection points have been used to determine critical parameters of TGS and MAPCB.

The time evolution of the temperature in a coke particle during its ignition in a heated gas has been analyzed in order to analytically determine the induction period with regard for the mass transfer of oxygen to the particle surface. It is shown that the ignition process can be divided into characteristic stages. But the inflection points in the time dependence of the particle temperature do not coincide with the stage boundaries and, hence, cannot be used for their identification. When determining the end of the heating stage analytically, it is better to associate it with a temperature tha

Density distribution functions for rut depths, stripping inflection points, and rutting resistance index (RRI) values used in the HWTT were obtained for mixtures with different nominal maximum aggregate size (NMAS) values and binder performance grades. Clear distinctions among the rut depth distributions for the high-temperature performance grade mixtures were observed in the laboratory-compacted specimens

Abstract:

Thermal analysis methods - such as TGA, DSC analysis, DTA, and TDS analysis - have been used in many reports to determine the activation energy for hydride decomposition. In our preceding work, we showed that the dehydriding rate of Mg-5Ni samples obeyed the first-order law and the Kissinger equation could thus be used to determine the activation energy. In the present work, we used the Mg-5Ni samples after activation. We obtained Tm at different heating rates by finding the temperature at which the ratio of the desorbed hydrogen quantity Hd change to T change, dHd/dT, was the highest from the

Abstract:

Non-renewable resources such as natural stone and asphalt are in short supply. Recycling technology, with its lower cost, has been used as the primary approach to asphalt pavement maintenance engineering. The inclusion of reclaimed asphalt pavement materials in producing new asphalt pavements may increase the risk of cracking. The strength and toughness of the asphalt mixture can be reduced. In this study, Hamburg wheel tracking tests (HWTT) were performed on rejuvenated asphalt mixtures with distinct maintenance processes. Different kinds of fibers have been used as additives to reinforce the

Abstract:

In long-period running of switch cabinet, the temperature of contact points will be rose by the big contact resistance, poor contact and longtime overloading. Overheat can cause oxidation of contact points and the increasing of contact resistance, and then the contact may be generated the spark and arc discharge. That is a bad circle. So the temperature of contact points can affect the reliability of switch cabinet. For detecting the temperature of contacts and the switch cabinet’s environment in Yanjin transformer substation, we design an Insulated FBG temperature sensor. The surveys of upper

Abstract:

The Microwave Radiation Imager (MWRI) onboard the FengYun satellite plays a crucial role in global change monitoring and numerical weather prediction. Estimating and correcting geolocation errors are important to retrieving accurate geophysical variables. However, the instantaneous field of view (IFOV) inter-channel deviation, which is mainly caused by the structure mounting error and measurement error of feedhorns, is less studied. In this present study, we constructed a general theoretical model to automatically estimate the IFOV inter-channel deviations suitable for conical-scanning instrum

SAGD technology has been successfully and widely applied in the development of superheavy oil and oil sand projects. Before normal SAGD process, some preheating ways are often needed to realize interwell hydraulic connection, and this means that determining reasonable SAGD conversion timing from the preheating stage is an essential precondition for good performance. Previous numerical simulations or qualitative analysis of temperature fall-off data are often adopted in the industry, but they have deficiencies in terms of dependent on static geological model or insufficient data utilization.

Abstract:

The use of integral abutment bridges with abutments supported on steel H-piles has become common practice in a number of states. These H-piles are subjected to various combinations of axial load and bending moment as the bridge undergoes temperature change. One commonly used approach to the design of these H-piles is, first, to perform an analysis to estimate the distance between inflection points on a pile and, second, to apply the AASHTO or AISC column design equations to the design of the pile. This approach neglects any lateral support provided by the soil between inflection points.Tests w

Abstract:

The Hough transform is commonly used for detecting linear features within an image. A line is mapped to a peak within parameter space corresponding to the parameters of the line. By analysing the shape of the peak, or peak locus, within parameter space, it is possible to also use the line Hough transform to detect or analyse arbitrary (non-parametric) curves. It is shown that there is a one-to-one relationship between the curve in image space, and the peak locus in parameter space, enabling the complete curve to be reconstructed from its peak locus.
