The reliability of rolling bearings is affected by white etching crack (WEC) or structure flaking (WSF) failures, causing tremendous commercial burdens for bearing manufacturers and operators. research the underlying failure mechanism has attracted interest from a large scientific community over decades. Despite significant amount efforts, root cause cracking still missing. Amongst other factor...

In this study, different plate fixing designs were tested in order to improve rock bolting performances. Instead of commonly used steel nuts, investigated by both laboratory and site studies. addition, the usability nuts energy absorbers made polyamide type engineering polymer was assess whether they are advantageous for aim supplying high-energy absorbing features. experimental deformation-con...

The paper considers the task of increasing durability and safe operation device by eliminating resonant beat vibration equipment during starting torque. During automobiles, contaminants form on surface individual parts assemblies, their high-quality cleaning is achieved chemical mechanical action these contaminants. use more active chemicals costly pollutes environment. Therefore, it desirable ...

Background: Hand dexterity a measure of hand flexibility and coordination can be affected by many factorsincluding grip strength. However, there are limited studies data about the association between handdexterity strength in Asian population. Hence, we aim to investigate relationship healthy males aged 18 25 years old population.Methods: Fiftyhealthy adult male participants 18-25 were recruite...

In this project, the quad processing machine for cutting, shaping, grinding and drilling machines is kept to be in same attachment. This eliminates risk of material handling table. unit driven by 0.25 H.P. three phase motor 1440 rpm. linked with cast-iron (CI) slider. enables slide get rotation movement into reciprocating motion having a stroke length 75mm. The head slotting can tilted getting ...

The field of artificial intelligence, broadly defined as the study and practice of designing intelligent agents, is at least six decades into its existence as a formal discipline. Sometimes called “computational” or “synthetic” intelligence, AI borrows from and informs a wide variety of subjects, including philosophy, psychology, linguistics, neuroscience, statistics, economics, and law. Techni...

Contents related to threat and associated cognitive processes are proposed to be the central characteristic of obsessive-compulsive disorder (OCD) according to 'threat-relatedness hypothesis'. However, evidence for attention bias toward emotionally salient stimuli using the emotional Stroop test is equivocal. This discrepancy could be due to methodological issues, mainly differences in the lexi...

World has entered into a new era where sustainability is the main factor to encounter the challenges of depletion of our reserves and environmental upsets. Wastewater is not only one of the main causes of irreversible damages to the environmental balances but also contributing to the depletion of fresh water reserves at this planet, generating threats to the next generation. A lot of industrial...

The benefits of an investment in an energy efficient durable good depend on the life of the investment. If the expected length of ownership is mis-estimated, this will bias calculations of the benefits of energy efficiency, including estimates of the energy efficiency gap. This paper estimates how expected ownership length affects household appliance choices. I leverage the fact that some types...

Renewable energy generation and electric vehicles (EVs) have attracted much attention in the past decade due to increasingly serious environmental problems as well as less and less fossil energy reserves. Moreover, the forms of energy utilization are changing with the development of information technology and energy technology. The term “energy hub” has been introduced to represent an entity wi...
