Coal Geology & Exploration
The evolution of rock internal damage is one of the causes of geotechnical engineering disasters, and revealing the response characteristics of key parameters during the rock failure could provide a basis for the identification instability state after rock failure, which is of great importance for the early warning and prevention of rock engineering disasters. Herein, the siltstone specimens with different damage degrees were prepared by cyclic loading-unloading tests, and uniaxial loading tests were carried out with the damaged specimens. On this basis, the relationship between the damage degree of specimen and the wave velocity, as well as the acoustic emission …

Rock and Soil Mechanics
In coal mining, the excavation of a coal-rock roadway and a thin coal seam will inevitably cause radial unloading of the coal-rock combination system. The radial unloading phenomenon is often accompanied by the rapid accumulation and release of energy, so it is necessary to investigate the energy evolution law of coal-rock combination specimens under the unloading confining pressure condition. To this end, the unloading confining pressure tests with different unloading rates were carried out for the coal-rock combination specimens. The results show that: (1) The axial loading and constant stress stages are the main energy storage stages of the combination …

Technical science and innovation
Vegetable raw materials, as an object of drying, are characterized by a large amount of water and a low content of dry substances. Vegetable raw materials have a capillary-porous structure. Food products contain both bound and free moisture at the same time. The removal of moisture from the material during drying depends on the total moisture content and the form of connection of moisture with the material. Adsorption and osmotic - bound moisture is retained at the interface of colloidal particles with the environment. Food products contain both bound and free moisture at the same time. The quantitative ratio between …

Mansoura Engineering Journal
Globally, a large proportion of a building's energy is consumed to achieve thermal comfort, as promoting energy efficiency and environmental sustainability of buildings is an important global goal. Therefore, the new building regulations are geared explicitly toward energy-saving projects. However, there are usually many competitive priorities, such as maximizing energy use in office buildings, leading to the complex multi-objective optimization topic. The main objective of this research was to reduce the energy consumed for cooling load in the office buildings in the city of Cairo, which is located in a hot desert climate. This was achieved by optimizing ten different …

Technical science and innovation
The article provides analytical information on the study of methods of treatment of used engine oils. The issues of ecological safety of storage, processing and use of automobile waste are considered. The problems of ecological safety of application of lubricants are inseparable from utilization of OWS, which are currently one of the most common man-caused waste that negatively affects all objects of environment - atmosphere, soil and water. It has been shown that water pollution by waste oil accounts for 20% of total techno-genic pollution, or 60% of petroleum product pollution. The study determined that obtaining oils with characteristics superior …

Bulletin of Chinese Academy of Sciences (Chinese Version)
The rapid development of the information society puts forward an ever-increasing urgent need for information storage, processing, and transmission capabilities. With the ending of Moore's Law, the semiconductor industry urgently needs to find new solutions. Lowdimensional materials are considered to be a new breakthrough in the semiconductor industry in the post-Moore era, because of the size characteristics of atomic-level thickness, the structural advantage of no dangling bonds on the surface, and the sensitivity to electrical and optical control methods caused by a large specific surface area. Songshan Lake Materials Laboratory has introduced a group of top scientists and established a …
Lessons Learned From Bp: Deepwater Horizon And The Transition To Renewables, Daniel Valle
Lessons Learned From Bp: Deepwater Horizon And The Transition To Renewables, Daniel Valle
Journal of Global Awareness
This paper analyzes the gradual transition of British Petroleum (BP), one of the world's largest oil and gas companies, into a renewable energy company focused on sustainability and the reduction of carbon emissions. BP's leadership and ethical practices are compared before and after the 2010 Deepwater Horizon disaster. The purpose of the comparison and the broader analysis of the transition is to identify how effective leadership can be used to transform a company with a suspect social responsibility record into a leader among its peers. Lessons learned from the disaster, and the subsequent transition conclude the research.

Modeling Electric Energy Generation In Ercot During Extreme Weather Events And The Impact Renewable Energy Has On Grid Reliability, Adam R. Ruthford, Bivin Sadler
SMU Data Science Review
This paper shows the inadequacy of current grid backup supplies, their ongoing threat to grid reliability, and the increased risk of customer blackouts. This paper also examines reliability concerns caused by renewable energy sources under more normal operating conditions. This paper seeks to model the impacts of extreme weather on ERCOTs grid. Unusual weather patterns require that the electrical grid operates in conditions outside normal operating parameters. Electrical system demand can spike well above normal levels. At the same time, weather influences can change the operating envelope of electrical generation equipment. The ERCOT grid has changed from its’ traditional mix …

Rock and Soil Mechanics
An RLW-2000 micro-computer servo-control rock triaxial testing machine was used to carry out triaxial cyclic loading and unloading experiments of saturated and natural shales under different confining pressures. The mechanical properties and hysteresis effects of two hydrated shales were analyzed. The evolution law of the damping ratio was discussed based on the energy principle. The experimental results show that as the cycle number increases, the cumulative residual strain increases gradually. The relative residual strain decreases first and then tends to a stable region, and finally increases rapidly prior to the rock damage. The deformation modulus of the saturated shale is …

Journal of System Simulation
Abstract: Using renewable energy in data center is an environment-friendly way to solve the problem of high energy consumption of data center. Since renewable energy is variable, delaying the jobs which has no strict deadline i a widely used strategy to maximize the usage of renewable energy. Meanwhile, turning the idle servers off can further reduce energy consumption. If the data required by the jobs to be processed are unavailable, some servers in sleep state need to be reactivated to guarantee that the data required by the jobs are available. Such operation may lead to energy waste due to the …

The energy-saving objective is introduced into the traditional material handling scheduling model for the tow-train and a multi-objective mixed integer programming model is constructed with two objective functions of minimizing the maximum line-side inventory and the total energy consumption. A forwards multi-objective dynamic programming based on the time window and dominance rules is presented to obtain the Pareto solutions: the definition for new states is given to obtain the Markov property, the time window and dominance …

Energy Consumption And Routing Model For First Responder Vehicles, Alex Rodriguez
The Pegasus Review: UCF Undergraduate Research Journal
The ongoing research and prototyping of electric vehicles (EVs) offers numerous opportunities to investigate their performance in various service contexts. As EVs are integrated into society, the reliable prediction of fuel consumption and routing time becomes particularly important in emergency response services. This project develops a preliminary stochastic model that can route and predict the energy consumption and travel time for hypothetical emergency vehicles operating on an electric battery cell. Using a Monte-Carlo framework, we constructed a routing model designed to minimize travel time and resource consumption under various simulated conditions. In doing so, we establish the foundation for balancing …
