Abstract:

As a significant component of rotation machinery, bearing plays a role in supporting and transmitting power. However, bearings are subject to complex operating conditions and are prone to failure. To avoid ineffectiveness and improve the reliability of bearings, a data-driven method is used to predict the remaining useful life (RUL). However, this method is less stable and can only forecast the RUL of bearings under training sample conditions. An ensemble deep, long-term, and short-term memory (EDLSTM) method is proposed to solve this problem. First, the feature of the forecast-bearing RUL was

Abstract:

The diagnosis of a rolling bearing for monitoring its status is critical in maintaining industrial equipment while using rolling bearings. The traditional method of diagnosing faults of the rolling bearing has low identification accuracy, which needs artificial feature extraction in order to enhance the accuracy. The one-dimensional convolution neural network (1D-CNN) method can not only diagnose bearing faults accurately, but also overcome shortcomings of the traditional methods. Different from machine learning and other deep learning models, the 1D-CNN method does not need pre-processing one

Abstract:

There is a relation between corporate risks, risk bearing ability and equity. In order to assess the risk bearing ability of a corporation, one reference figure is equity, understood as the sum of legal capital and reserves, free reserves and accrued profits. Equity shows the risk bearing ability related to the risk of asset reduction as well as the ability of the corporation to attract new liquidity by increasing debts, in case of a negative free cash flow. Equity is the risk reserve of the corporation. The relation between equity and risk bearing ability allows defining the necessary amount

Computer simulations of a number of journal bearing’s geometries utilising acoustic levitation were carried out.

Deformations of analysed variants of the bearing’s shape were generated by numerical simulations utilising the finite element method. For the chosen shapes of geometry, prototype bearings were made and their usefulness verified experimentally. As a res

Abstract:

Wear particle production in load-bearing orthopaedic implants is one of the major factors currently limiting the service life of the implant. Most of the research carried out to date in attempting to solve this problem has used the approach of finding more wear-resistant biocompatible material pairs. In contrast, other researchers have attempted to reduce wear by encouraging elastohydrodynamic film formation through the use of elastomeric bearing surfaces. Unfortunately, these elastomeric bearing surfaces have poor tribological properties when a fluid film is not present. Boundary lubrication

Enhancement and AI create moral dilemmas not envisaged in standard ethical theories. Some of this stems from the increased malleability of personal identity that this technology affords: an artificial being can instantly alter its memory, preferences, and moral character. If a self can, at will, jettison essential identity-giving characteristics, how are we to rely upon, befriend, or judge it? Moral problems will stem from the fact that such beings are para-persons: they meet all the standard requirements of personhood (self-awareness, agency, intentional states, second-order desires, etc.) bu

Chapter 1 uses a historical, and notably unconventional, example of witnessing to demonstrate how bearing witness involves sometimes radical and purposeful rhetorical invention (or reinvention) of historical fact.

This counterintuitive example indicates that witnesses bear witness in public only if social, political, or moral authorities permit their testimonies.

Abstract:

Abstract The condition monitoring of bearings and wheels is pivotal in ensuring the safe and efficient transport of freight within the railway industry. Bearing seizures remains an issue that can lead to catastrophic train derailments, affirming the importance of effective monitoring practices. Existing wayside detection devices, such as Hot Bearing Detectors (HBDs) and Trackside Acoustic Detection Systems (TADS™), track, respectively, the operating temperature and acoustic emissions of bearings at discrete intervals as trains pass by these systems. However, these systems have demonstrated ina

Abstract:

Abstract Fully ceramic bearings have been demonstrated to provide a forty to fifty percent reduction in weight over steel bearings. They can also provide improved reliability due to increased corrosion protection. One of the primary challenges to incorporating ceramic bearings is the coefficient of thermal expansion mismatch between the ceramic bearing races and its mating surfaces. The application of a tolerance ring was developed to address these challenges. The tolerance ring was applied between the inner bearing race and the pinion shaft to retain the race and absorb the thermal expansion

Abstract:

One type of test performed for evaluating bearings for application into turbomachinery is the synchronous bearing response to rotor imbalance. This paper presents rotordynamic tests on a rotor system using a 70mm diameter damped gas bearing reaching ultra-high speeds of 50,000 rpm. The main objective of the study was to experimentally evaluate the ability of the damped gas bearing to withstand large rotor excursions and provide adequate damping through critical speed transitions. Two critical speeds were excited through varying amounts and configurations of rotor imbalance, while measuring syn

Abstract:

A Clegg Impact Tester, also known as a Clegg Hammer, is a portable device invented by Dr. Baden Clegg to assess surface shock absorption and bearing capacity. It measures the strength of soils, aggregates, and synthetic materials for roads and sports surfaces. The tester consists of a compaction hammer, guiding tube, and piezoelectric accelerometer. It quantifies a surface's ability to withstand structural load and offers insights into strength, stiffness, and stability. The hammer is dropped from a specific height, and its impact is measured. Clegg Impact Testers are used for various applicat

Abstract:

Similar to most metering technologies, turbine meters are known to be affected by abnormal flow or abnormal mechanical conditions which can cause bias in flow measurement. These types of flow conditions include blockage at the flow meter or straightening vanes, grime or liquid contamination on the internal meter components, damage to the internal meter components, and pulsation in the flow. With the introduction of ultrasonic and Coriolis meters for gas applications, the natural gas industry has embraced the concept of meters with embedded diagnostic capabilities.

Abstract:

Our previous work indicated that suspension-cultured plant cells show remarkable flexibility in altering cell wall structure in response either to growth on saline medium or in the presence of the cellulose synthesis inhibitor 2,-6-dichlorobenzonitrile (DCB). We have continued to analyze the structure of these modified cell walls to understand how the changes modify wall strength, porosity, and ability to expand. The major load-bearing network in the walls of DCB-adapted dicot cells that lack a substantial cellulose-xyloglucan network is comprised of Ca2+-bridged pectates; these cells also hav

The genome of Cmm contains numerous genes encoding for extracellular serine proteases and cell wall degrading enzymes. The first objective was to elucidate the role of secreted serine proteases in Cmm virulence. Mut

In the present research we attempted to enhance bee visitation to Male Sterile (M-S) tomato flowers generally used in the production of hybrid seeds. These flowers that lack both pollen and nectar are unattractive to bees that learn rapidly to avoid them. The specific objects were to elucidate the chemical composition of the exocrine products of two bumble bee species the North American Bombus impatiens and the Israeli B. terrestris.

Puncture tests of the ring nets and two-point traction tests of the three-ring chains with various wire-ring specifications were conducted. Correlation analysis was used to test the results between ring nets and chains, revealing that three structural performance indicators of the test specimens were strongly related.

Abstract:

A simplified analysis model of the overall steel frame with external wall panels is established by finite element numerical method, and the influence of external wall panels on the internal force and seismic performance of the steel frame is studied. Pushover analysis and cyclic loading analysis are carried out on the simplified model. The results show that the external wall panel can improve the initial stiffness and ultimate bearing capacity of the steel frame, and after considering the external wall panel, the shear demand of the column increases accordingly.
