Rocscience Phase2 v8.024 x64 [Size: 209 MB] ... RS2 (Phase2 8.0) is a powerful 2D finite element program for soil and rock applications (RS2 = Rock and Soil 2-dimensional analysis program). RS2 can be used for a wide range of engineering projects and includes excavation design, slope stability, groundwater seepage, probabilistic analysis, consolidation, and dynamic analysis capabilities.

Complex, multi-stage models can be easily created and quickly analyzed - tunnels in weak or jointed rock, underground powerhouse caverns, open pit mines and slopes, embankments, MSE stabilized earth structures, and much more. Progressive failure, support interaction and a variety of other problems can be addressed. RS2 offers a wide range of support modeling options. Liner elements can be applied in the modeling of shotcrete, concrete, steel set systems, retaining walls, piles, multi-layer composite liners, geotextiles, and more. Liner design tools include support capacity plots, which allow you to determine the safety factor of reinforced liners. Bolt types include end anchored, fully bonded, cable bolts, split sets, and grouted tiebacks. One of the major features of RS2 is finite element slope stability analysis using the shear strength reduction method. This option is fully automated and can be used with either Mohr-Coulomb or Hoek-Brown strength parameters. Slope models can be imported or exported between Slide and RS2 allowing easy comparison of limit equilibrium and finite element results. RS2 includes steady-state, finite element groundwater seepage analysis built right into the program. There is no need to use a separate groundwater program. Pore pressure is determined as well as flow and gradient, based on user defined hydraulic boundary conditions and material conductivity. Pore pressure results are automatically incorporated into the stress analysis. Material models for rock and soil include Mohr-Coulomb, Generalized Hoek-Brown and Cam-Clay. Powerful new analysis features for modeling jointed rock allow you to automatically generate discrete joint or fracture networks according to a variety of statistical models. With new 64-bit and multi-core parallel processing options RS2 can solve larger and more complex models in shorter times.

Laura Graesser, Wah Loon Keng ... 416 pages - ISBN-13: 978-0135172384 - ISBN-10: 0135172381 ... Publisher: Addison-Wesley Professional; (December, 2019) - Language: English.

The Contemporary Introduction to Deep Reinforcement Learning that Combines Theory and Practice: Deep reinforcement learning (deep RL) combines deep learning and reinforcement learning, in which artificial agents learn to solve sequential decision-making problems. In the past decade deep RL has achieved remarkable results on a range of problems, from single and multiplayer games–such as Go, Atari games, and DotA 2–to robotics.

Foundations of Deep Reinforcement Learning is an introduction to deep RL that uniquely combines both theory and implementation. It starts with intuition, then carefully explains the theory of deep RL algorithms, discusses implementations in its companion software library SLM Lab, and finishes with the practical details of getting deep RL to work. This guide is ideal for both computer science students and software engineers who are familiar with basic machine learning concepts and have a working understanding of Python: Understand each key aspect of a deep RL problem + Explore policy- and value-based algorithms, including REINFORCE, SARSA, DQN, Double DQN, and Prioritized Experience Replay (PER) + Delve into combined algorithms, including Actor-Critic and Proximal Policy Optimization (PPO) + Understand how algorithms can be parallelized synchronously and asynchronously + Run algorithms in SLM Lab and learn the practical implementation details for getting deep RL to work + Explore algorithm benchmark results with tuned hyperparameters + Understand how deep RL environments are designed.

Francis D. K. Ching ... 256 pages - Publisher: Wiley; 6th Edition (April, 2015) ... Language: English - AmazonSIN: B00WJZ2PPC.

The bestselling guide to architectural drawing, with new information, examples, and resources: Architectural Graphics is the classic bestselling reference by one of the leading global authorities on architectural design drawing, Francis D.K. Ching. Now in its sixth edition, this essential guide offers a comprehensive introduction to using graphic tools and drafting conventions to translate architectural ideas into effective visual presentations, using hundreds of the author's distinctive drawings to illustrate the topic effectively. This updated edition includes new information on orthographic projection in relation to 3D models, and revised explanations of line weights, scale and dimensioning, and perspective drawing to clarify some of the most difficult concepts. New examples of modern furniture, APA facilities, and presentation layout provide more up-to-date visuals, and the Reference Center features all new animations, videos, and practice exercises.

Architectural graphics are key tools for conveying design through representation on paper or on screen, and this book is the ultimate guide to mastering the skill, then applying your talent to create more effective design communication. + Understand multiview, paraline, and perspective drawing + Master interior sections using a variety of techniques + Render tonal value, enhance depth, and convey illumination + Develop professional-quality layouts for presentations. Architectural graphics both inform the design process and serve as the means by which a design is interpreted and built. Complete mastery of the tools and conventions is essential to the successful outcome of any project, and mistakes can cause confusion, time delays, increased costs, and possible catastrophe. Architectural Graphics is the comprehensive guide to professional architectural drawing, with insight from a leading authority in the field.
