Construction of Shipping Linked Data Lifecycle Model and Its Application in Semantic Navigation
Authors: Liang Yiduo 
Published: February 2021

Abstract
As one of the most important government data assets, shipping data has attracted more and more attention from stakeholders. The term linked data refers to a set of best practices for publishing and linking structured data on the web. The application of linked data technology to open the shipping data can promote the transparency and reusability of data. Many shipping data have been placed on the network as linked data. However, the existing construction of shipping linked data does not consider the concept of lifecycle, and the concept of lifecycle naturally lies in the link data itself. Therefore, this paper attempts to propose a linked data lifecycle model to assist in publishing shipping data as linked data on the Web. We first conduct a systematic analysis of the typical lifecycle model. On this basis, a new linked data lifecycle model is proposed, and the role of each step of the model is also explained. In particular, we take domain modeling as the first step of the model and discuss the key role of it in publishing linked data. Taking the voyage data as an example, we show in detail how to use the proposed model to construct shipping linked data. Then, a specific semantic navigation case based on the above data is given to prove the added value of the linked data. The results show that the lifecycle model proposed in this paper is suitable for the publication of shipping data and is convenient for future expansion and maintenance.

Creation and utilization of straightness standard due to reciprocal measurement of linear stage
Authors: Furutani R , Yamaguchi K 
Published: February 2021

Abstract
In general, profile measuring machine consists of a displacement sensor and movable mechanism. However, as the movable mechanism has profile errors, the output of displacement sensor includes the profile error of the movable mechanism. Therefore, it is necessary to distinguish the profile error of the movable mechanism from the output of the displacement sensor. So we propose a new way to distinguish the profile of object from movable profiles. The new method requires two linear stages and the displacement sensor. Two stages can move and locate independently, and displacements are measured at every location. The profile of object is calculated from the output of displacement sensor. Finally, the pre-known profile was measured by the proposed method, and the result is compared with the pre-known profile.
Application of the hereditary creep theory in assessing the effect of temperature influence on the strength of carbon fibre plastics

Published: February 2021

Abstract
One of the problems, which engineers face in using of carbon-reinforced composites, is the large scatter of the strength characteristics. To diminish scatter the method of the merger of tests results under varied climatic conditions might be applied. The aim of this merge is diminishing the scatter of the strength test results, and therefore improving the strength estimation accuracy. It is also in connection with the problem of the impact of climatic changes on the material properties. The climate impact is significantly larger in composites than in metals. To deal with those two problems the heredity mechanics developed earlier by Russian academician Ju. N. Rabotnov and his successors has been applied. The developed earlier modification of this theory, related to climate influence, has been applied to the problem of experimental data merger, obtained under varying temperatures, into one generalized set. For consideration of the orthotropy properties which are specific for reinforced composites, it was proposed the experimental investigation of the specimens cut in three different directions. The Rabotnov’s heredity equation should be written in tensor form. The property of viscoelasticity, which is inherent for carbo-plastics materials (especially under the elevated temperatures), is utilized in the decision of this problem. Experimental data and results of the model application are presented.
Nanomaterials of Fe, Al and Ti, in the reduction of potentially reactive basalt aggregate in Portland cement dosages: deposition of coatings by plasma

Published: February 2021

Abstract
The mitigation of the effects of the alkali aggregate reaction (AAR) in cement mortars and concretes, with the addition of nanomaterial based on Fe, Al and Ti, on reactive aggregates was investigated. The coatings were prepared by the plasma technique. For this purpose, a rotational system was designed to obtain continuous nanometric films. The addition of metal-based nanomaterials and their metallic oxides (Fe, Al and Ti) helped in the reduction of the AAR process, by the formation of nanoclusters with potential reduction of the effects of the aggregated alkali reaction. This occurs by the modification of the degree of wettability of the interface or even a possible chemical interaction of the deposited films with the reactive components of the rock, eliminating the contact of the alkalis of the cementitious paste with the reactive silica of the aggregates.
Random processes imitation in the problem of fatigue under variable loading
Authors: Makhutov N , Gadolina I , Dinyaeva N 
Published: February 2021

Abstract
There is strong evidence, that the extrema and their sequence play a major role in metal fatigue. Due to this random testing with extrema control might be preferable, compared with the testing with generating by the spectral densities. The method is proposed allowing to generate random processes with the stable integral characteristics of cumulative distributions, and at the same time, being random by their nature. The algorithm consists of two steps. The first one is creating the random sequence of extrema, basing on the target Markov matrix, filled up on the base of the loading process, recorded during exploitation. The next step is the creation of the random process with its continuous first derivate. The special concatenation procedure was proposed and had been proved to create the continuous function reconstruction out of the point-wise specification (local maximums and minimums sequence). To judge the frequency content a regression analysis of two random variables was performed. The obtained continuous process might be undergone by the spectral analysis to get the spectral density function, which might be required in applying some methods for random fatigue estimation. The main trait of the proposed method is the coincidence of the rain-flow cycle counting characteristics of the initial and the resulting processes.

Authors: Miyazawa M , Wajima T 
Published: February 2021

Abstract
Glass fiber-reinforced plastics (GFRPs) are composite materials with high strength and flame retardancy; however, their disposal process is expensive, causing illegal dumping. Herein, recycling of waste GFRPs using pyrolysis with KOH under an inert atmosphere was attempted by the gasification of resin and conversion of glass fibers into soluble silicate. The pyrolysis behavior of the GFRP, characteristics of the obtained residue, composition and yield of the generated gas, and extracted amount of silica in the solution obtained using KOH were investigated. The results indicated that the gasification of the resin and conversion of the glass fiber into soluble silicate were promoted by pyrolysis with KOH. With an increase in the heating temperature, KOH addition amount, and heating time, the yield of gases, especially flammable gases (H2 and CH4), and the extracted amount of silica increased, whereas the residual rate decreased. The amount of silica extracted using 1 M HCl is higher than that extracted using distilled water. Compared with those obtained using NaOH, the yield of gases and specific surface area of the residue achieved using KOH are superior, while the extracted amount of silica obtained using NaOH is higher than that acquired using KOH.

Published: February 2021

Abstract
For an inclined high-rise steel structure, for example, the new headquarters of China Central Television (CCTV), if the structural members are manufactured and erected according to the Structural Design Configuration (SDC), it may lead to a considerable deviation between the structural construction completed configuration and the SDC because of its continuously inclined deformation during the installation. And surely it is impossible to connect the cantilever accurately without taking Pre-set Deformation Value (PDV) for structural members during the erection. This paper introduced the concept of the PDV, which includes manufacture pre-set deformation value and erection pre-set deformation value. A new computational method, namely two stage comprehensive iteration method, to determine PDVs of the new CCTV headquarters is proposed. A number of numerical results are obtained which have been used as guidelines for the construction of the new CCTV headquarters.

Published: February 2021

Abstract
Thermo-mechanical stresses developed in a disk, inner boundary of which is subject to the nonstationary thermo-mechanical loadings due to variation in temperature and pressure inside the disk is considered in the presented paper. Problems of theoretical analysis are divided and described as follows: The first problem implies analytical solution of the heat conduction equation with nonhomogeneous boundary conditions of Robin type, and the second problem deals with obtaining analytical solution of dynamic equation of displacement for nonisothermal elastic body (Navier equation) with traction boundary conditions in the plane strain case of uncoupled thermo-elasticity. Finite Hankel transform is used to solve the problems. Two sets of orthogonal basis functions necessary for integral transform are obtained. The first one corresponds to the boundary conditions written for the heat conduction equation, and the second fits the boundary conditions for Navier equation. Integrals defining elements of transformation matrix between the two sets of basis functions are evaluated analytically. In general, convenient method of obtaining analytical solution of linear hyperbolic equation with nonhomogeneous term, which itself is solution of nonhomogeneous parabolic equation, is elaborated within the presented work. Using finite difference method, discrete counterparts of the described problems are constructed and, via the built-in ordinary differential equation (ODE) solvers in MATLAB, numerical solutions are obtained, which exhibit excellent accordance with analytical ones.
Effect of ambient temperature and heating time on high-power LED
Authors: Peng D S , Liu K L 
Published: February 2021

Abstract
LED is widely used in various fields as a new style of light sources. Today the efficiency of LED electro-optical conversion is only 20%, and the rest of energy release in the form of heat, which is generating higher junction temperature. The junction temperature rise will cause serious thermal problems and affect the performance of the LED. In this paper, we mainly focus on the research of the thermal problem of the high-power LED. The result shows that the junction temperature and thermal resistance of the R and G-based LEDs increase with the increase of the ambient temperature and the heating time. This leads to an increase in operating current, ambient temperature, and usage time during operation of the high-power LED, which causes the low luminous efficiency of the LED, thereby increasing the amount of heat generated, which easily causes aging of the device and permanent light decay. Therefore, reducing the thermal resistance and junction temperature in the previous LED design will greatly help the thermal and optical improvement of the LED.

Abstract
In order to analyze the progressive collapse resistance of single-layer reticulated shells, the finite element model of single-layer reticulated shell structure was established by ABAQUS software, and the method of removing key component constraints was used to simulate the progressive collapse resistance of the single-layer reticulated shell structure. The results show that the removal of the key components can cause the continuous failure of the upper members of the reticulated shell, and then lead to the progressive collapse of the whole structure.

Published: February 2021

Abstract
Double Parallelogram Lifting Mechanism (DPLM) is a multi-linkage mechanism adopted as the lifting mechanism of the designed robot in this paper. DPLM is designed based on Double Parallelogram Mechanism (DPM), making it a compact and stable multi-linkage mechanism with a low retracted height and a great working height. This paper investigates the condition in which DPLM obtains static equilibrium at any height using Hookean springs and the minimization of the motor’s required torque exertion against the gravitational moment of the weight of the mechanism. A mathematical model describing all the factors involved in moment balancing of DPLM is derived and established in MATLAB and is verified through experiments with a virtual prototype conducted in SOLIDWORKS. The obtained results show that the magnitude of the moment exerted by the tension of a spring can be determined not only by its exact installation positions but also by its D value, which is the difference in the distances between the two installation points of a spring and their respective rotation axes. An optimization method based on minimizing the RMSE of the unbalanced moment for DPLM is introduced.

Authors: Ho H C , Xiao T Y , Chen C , Chung K F 
Published: February 2021

Abstract
This paper presents recent research findings on true stress strain characteristics of normal strength S275, S355 and high strength S690 steels to EN 10025:2005. It aims to provide generalized constitutive models for analysis and design of steel structures. Comprehensive experimental and numerical investigations into mechanical properties of the structural steels have been carried out based on test results of nine monotonic tensile tests. Non-uniform stress and strain distributions within the necked region are found when the test coupons are under very large deformation. After corrections to the stress and strain non-uniformities by Instantaneous Area Method with successive approximations, true stress strain characteristics of the tested steels were successfully quantified as generalized constitutive models. Moreover, the microstructures of the typical structural steels haven been carefully examined, and their microstructural constituents are successfully quantified by Digital Image Analytics. The research findings are very important for subsequent numerical investigations into the structural performance of steel structures under very large deformations up to fracture. The authors are grateful for the financial supports from the Research Grants Council of the Government of Hong Kong SAR, and the CNERC for Steel Construction (HKB).
