Global Warming

Global Warming

Morteza Soltani; Hossein Gholami; Shahide Dehghan

Lap Lambert Academic Publishing
2022
pokkari
Global warming is the long-term heating of Earth's surface observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere. This term is not interchangeable with the term "climate change."Since the pre-industrial period, human activities are estimated to have increased Earth's global average temperature by about 1 degree Celsius (1.8 degrees Fahrenheit), a number that is currently increasing by more than 0.2 degrees Celsius (0.36 degrees Fahrenheit) per decade. The current warming trend is unequivocally the result of human activity since the 1950s and is proceeding at an unprecedented rate over millennia.

Dam Stability

Dam Stability

A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC.

The objective of this book is to provide students with fundamental knowledge of finite element analysis and how to apply this knowledge to the solution of civil engineering problems at intermediate and advanced levels. At the end of this unit, students should acquire knowledge of methods of formulating finite element equations, basic element types, the use of finite element methods for solving problems in structural, geotechnical and continuum analysis and the use of finite element software packages. The syllabus comprises introduction to finite element theory, analysis of bars, beams and columns, and assemblages of these structural elements; analysis of elastic continua; problems of plane strain, plane stress and axial symmetry; use, testing and validation of finite element software packages; and extensions to apply this knowledge to problems encountered in engineering practice. On completion of this unit, students will have gained the following knowledge and skills: Knowledge of methods of formulating finite element equations. This will provide students with an insight into the principles at the basis of the FE elements available in commercial FE software.

Water Engineering in Numerical Method

Water Engineering in Numerical Method

Shahide Dehghan; Hossein Norouzi; Hossein Gholami

Lap Lambert Academic Publishing
2023
pokkari
Underground water sources are one of the most important sources of water supply, so their modeling is important. In the meantime, studying and investigating the fluctuations of the underground water level in terms of management studies, creating engineering structures, agricultural uses and obtaining high quality underground water is of great importance. Most of the demand for drinking and agricultural water in Mashgin Shahr plain is also supplied through underground water. Four artificial intelligence models, including forward neural network, backward neural network, Sagno fuzzy logic and support vector machine were used to predict the groundwater level.
