Authors: Zhan Jun , Cheng Longsheng , Peng Zhaiming 
Published: November 2019

Abstract
In order to effectively identify the various faults of rolling bearings and the severity of the faults, an intelligent fault diagnosis system based on variational mode decomposition and multi-tree Mahalanobis Taguchi system with multiple mahalanobis distance was proposed. Vibration signals were decomposed into multiple BLIMFs by variational mode decomposition, and time domain and frequency domain features were extracted. The multiple mahalanobis distance method was used to solve the problem of many features in the diagnosis system. By using the advantages of Mahalanobis Taguchi system in features optimization, sensitive modal components for diagnosis and recognition were selected. Multi-tree Mahalanobis Taguchi system was constructed for intelligent identification of multiple fault states. Finally, rolling bearings fault data was tested to verify the accuracy of the algorithm and compared with other algorithms. The results show that the algorithm can simplify the diagnosis system, reduce training time and improve the recognition accuracy.

Published: November 2019

Abstract
In order to improve the modeling accuracy of the motorized spindle, a comprehensive thermal contact resistance (TCR) modeling method was proposed. The fractal theory was introduced to calculate the joint thermal contact resistance. The W-M function and the M-B fractal model were established to characterize the microscopic contour of the rough surface. The bulk thermal resistance, constrained thermal resistance, micro-gap thermal resistance and overall thermal contact resistance of the rough surface of different materials were discussed. The finite element method(FEM)was used to establish the multi-physics coupling analysis model of the motorized spindle, adding the theoretical calculation of thermal contact resistance in the joint surface of the motorized spindle. The temperature rise and deformation variation of the motorized spindle were simulated under the condition of thermal contact resistance. The simulation results demonstrate the influence of thermal contact resistance on the temperature and thermal deformation of the motorized spindle. The results show that when the thermal resistance of the high-speed motorized spindle is considered, the temperature rises and the deformation increases, and the accuracy of the model is more accurate, which is closer to the actual processing.

Published: November 2019

Abstract
Home appliance test is an essential part of the R&D process. However, since home appliance test must be carried out under certain circumstances, it makes the development cycle longer. If it is possible to predicting the home appliance test data, it will improve the efficiency of home appliance development. Sequence to sequence model has been proved that it has a strong ability to map the input sequence and output sequence and it has been widely used in machine translation tasks. In order to solve the home appliance test data prediction problem, we firstly tried to apply sequence to sequence model to predict numerically continuous time series data. Our experiments proved that our model can predict the data of relatively long-time steps when inputting data of relatively short time steps. In our experiment, the mean absolute percentage error of the prediction of our model is about 0.1%. Our approach has a strong generalization ability and performs well in different experimental scenarios. Finally, we believe that the sequence to sequence method performs satisfactorily on prediction problems for continuous time series data. With this model, we can obtain more accurate results than traditional methods and it is meaningful for the R&D of home appliances.

Published: November 2019

Abstract
In this work, the study of the effect of mechanical treatment of TiNi powder on structure and phase composition is presented. The powder was processed in high-energy planetary ball mill for different time. It has been shown that the average particle size measured by scanning electron microscopy changes not monotonous after mechanical treatment, but form of particles changes. The coherently diffracting domain size decreases from 43 nm to 5 nm with increasing of mechanical treatment time that significantly less than the average particle size measured by laser diffraction method and the average particle size calculated from the obtained values of the specific surface. That is to say, the powder particles consist of several crystallites. The width of all peaks changes after 10 s of mechanical treatment that can correspond to an increasing of the defect density. The lattices parameters of all phases change not more than 0.8 % after mechanical treatment. Two processes compete during mechanical treatment, characterizing either brittleness or plasticity. Many defects appear during mechanical treatment stipulate a quasi-amorphous state with increasing of mechanical treatment time.

The region produces up to 45% of nickel, and 13% of copper, and the majority of rare-earth metals, niobium, and titanium compounds from the regional minerals. The ores mined from the existing deposits can be used for production of up to 30 various concentrates. The materials produced from the regional minerals include metal nickel, cobalt, copper, titanium, niobium, rare-earth metals, steel; sealants, components of electrode coatings and welding fluxes, sorbents for disposal of radioactive waste and wastewater containing heavy non-ferrous metals and other contaminants, high-porous heat insulation and fire-resistant materials for arctic application, cement, concretes with improved resistance to frost and sea water. In satisfying demand for new materials, the first and foremost objective is to establish a pilot engineering base for adaptation of process flowsheets, and collection of data for design and construction of new operations. Successive implementation of this objective requires concentrated efforts of scientists and engineers focused on implementation of the Kola Chemical and Technological Cluster Project, which enables to improve significantly the economy of minerals use by means of products of their deep processing. At the first stage of the Cluster operation, a process of new titanium sorbents production will be established to solve environmental issues — treatment of non-ferrous metals industry wastewater from heavy metals, and processing of liquid radioactive waste accumulated in the Arctic zone of Russian Federation.

Abstract
The complete set of optical parameters of micron-sized polycrystalline CH3NH3PbI3−xClx films deposited by the vacuum co-evaporation of lead iodide and methylammonium chloride is determined by analysis of oscillating optical transmittance and reflectance spectra in the wavelength range 400–1000 nm. It is shown that for a medium and weak absorption region the envelope method is valid for the extraction of refractive index, extinction and absorption coefficient when is using only transmittance spectra. As well thickness of the film is determined from transmittance and reflectance spectra with interference-effect. The absorption coefficient for the strong absorption region and optical band gap (direct transition at E
opt = 1.62 eV) are calculated based on transmittance and reflectance spectra by using conventional approximated formulas.

Published: November 2019

Abstract
Aluminum alloy based metal matrix composites are widely used in aerospace, military and automotive industry. The aluminium grades used in present research work are Aluminium alloy 6061, Aluminium alloy 2024, LM6. In this research, composites with Aluminum alloy as matrix with 6 weight % of nano alumina as reinforcement were fabricated using two processing technique namely, powder metallurgy technique (cold pressing and microwave sintering), and by squeeze casting technique. Thus fabricated samples were used to study the effect of processing technique on mechanical properties and wear aspects of the composite. Scanning electron microscope data and mechanical property characteristics reveals the presence of nano alumina particles and their uniform distribution in case of powder metallurgy processed samples. Mechanical and wear properties achieved on the fabricated samples were compared with the existing aerospace brake pad material. The data related to wear characteristics correlated with the number of landings for the existing brake pad material is considered as the bench mark data and the feasibility of replacing it with the developed composites were studied.

Published: November 2019

Abstract
Superconducting QUantum-Interference Devices (SQUIDs) make magnetic resonance imaging (MRI) possible in ultra-low microtesla-range magnetic fields. In this work, we investigate the design parameters affecting the signal and noise performance of SQUID-based sensors and multichannel magnetometers for MRI of the brain. Besides sensor intrinsics, various noise sources along with the size, geometry and number of superconducting detector coils are important factors affecting the image quality. We derive figures of merit based on optimal combination of multichannel data, analyze different sensor array designs, and provide tools for understanding the signal detection and the different noise mechanisms. The work forms a guide to making design decisions for both imaging- and sensor-oriented readers.

Mindfulness and Meditative Movement Interventions for Men Living With Cancer: A Meta-analysis
Authors: Ford C Graham , Vowles Kevin E , Smith Bruce W , Kinney Anita Y 
Published: November 2019

AbstractBackgroundMindfulness-based interventions, Tai Chi/Qigong, and Yoga (defined here as meditative cancer interventions [MCIs]) have demonstrated small to medium effects on psychosocial outcomes in female breast cancer patients. However, no summary exists of how effective these interventions are for men with cancer.PurposeA meta-analysis was performed to determine the effectiveness of MCIs on psychosocial outcomes (e.g., quality of life, depression, and posttraumatic growth) for men with cancer.MethodsA literature search yielded 17 randomized controlled trials (N = 666) meeting study inclusion criteria. The authors were contacted to request data for male participants in the study when not reported.ResultsWith the removal of one outlier, there was a small effect found in favor of MCIs across all psychosocial outcomes immediately postintervention (g = .23, 95% confidence interval [CI] 0.02 to 0.44). Studies using a usual care control arm demonstrated a small effect in favor of MCIs (g = .26, 95% CI 0.10 to 0.42). However, there was insufficient evidence of a superior effect for MCIs when compared to an active control group, including attention control. Few studies examined both short-term and long-term outcomes.ConclusionsThere is evidence for MCIs improving psychosocial outcomes in male cancer survivors. However, this effect is not demonstrated when limited to studies that used active controls. The effect size found in this meta-analysis is smaller than those reported in MCI studies of mixed gender and female cancer patient populations. More rigorously designed randomized trials are needed that include active control groups, which control for attention, and long-term follow-up. There may be unique challenges for addressing the psychosocial needs of male cancer patients that future interventions should consider.
A Dilemma for Modest Actual Intentionalism
Authors: Lin Szu-Yen 
Published: November 2019

Abstract
Modest actual intentionalism is a major position on interpretation in contemporary analytic aesthetics. The position consists of a disjunctive formulation according to which work-meaning is determined by the author’s intention when such intention succeeds or by non-intentionalistic factors when it fails. I challenge the disjunctive view by presenting a constructive dilemma, the conclusion being that modest actual intentionalism ends up either making non-intentionalistic factors idle or making authorial intent superfluous.
