Module 5-Modelling & Simulation: Thermodynamic and FEM Analysis in SPS
 
49:11
Speaker: Dr. Zhe Zhao (University of Stockholm) Abstract:Spark Plasma Sintering (SPS) has been an attractive sintering technique for preparing nanostructured ceramics and composites for more than 10 years, but there is still no clear image about the sintering mechanisms behind the enhanced densification. Here we will use traditional sintering and creep deformation kinetic method to analysis the densification process in SPS in order to shade light on the potential mechanisms which make SPS different from the other normal pressure-assisted sintering techniques. As another potential technical obstacle to SPS applications for mass-production, the intrinsic temperature and stress profi les are also analyzed by FEM. Both transient and equilibrium state are considered. The knowledge from this lecture can be used as the general guideline for SPS experiments in Labs or industries.
Stable Neo-Hookean Flesh Simulation (SIGGRAPH 2018)
 
04:26
Stable Neo-Hookean Flesh Simulation SIGGRAPH 2018 Breannan Smith Pixar Animation Studios Fernando De Goes Pixar Animation Studios Theodore Kim Pixar Animation Studios Nonlinear hyperelastic energies play a key role in capturing the fleshy appearance of virtual characters. Real-world, volume-preserving biological tissues have Poisson’s ratios near 1/2, but numerical simulation within this regime is notoriously challenging. In order to robustly capture these visual characteristics, we present a novel version of Neo-Hookean elasticity. Our model maintains the fleshy appearance of the Neo-Hookean model, exhibits superior volume preservation, and is robust to extreme kinematic rotations and inversions. We obtain closed-form expressions for the eigenvalues and eigenvectors of all of the system’s components, which allows us to directly project the Hessian to semipositive definiteness, and also leads to insights into the numerical behavior of the material. These findings also inform the design of more sophisticated hyperelastic models, which we explore by applying our analysis to Fung and Arruda-Boyce elasticity. We provide extensive comparisons against existing material models. https://graphics.pixar.com/library/StableElasticity/
1.4 Modeling and simulation of dynamical systems (AE3B35MSD): Second-order models
 
07:01
Video lecture for the undergraduate course on modeling and simulation of dynamical systems given within a study program "Cybernetics and Robotics" at Faculty of Electrical Engineering, Czech Technical University in Prague, Czech Republic. The course website is http://moodle.fel.cvut.cz/courses/a3b... (you can switch the language of the web). In this video we introduce yet another popular format of a mathematical model of dynamical systems - the second-order models. These are particularly popular in mechanical systems, including robotics. We will show that the popular second Newton's law m x''(t) = F(t) is perfectly appropriate not just for a description of (one-dimensional) motion of a single mass but for coupled multiple masses as well. The x(t) should now be interpretted as a vector of positions (and/or possibly angles) and the coefficient(s) (mass, damping, stiffness) are now matrices. These matrices can be constant or they can depend on the actual mechanical configuration, in which case the model is nonlinear (but with a very neat structure). We will encounter the latter in a lecture on Euler-Lagrange modeling of robotic manipulators.

Finite element simulation of bullet impacting skull (2/2)
 
00:02
An advanced physics-based simulation of firearms injury to the human cranium is presented, modeling by finite elements the collision of a firearm projectile into a human parietal bone. The space-discretized equations of motion are explicitly integrated in time with Newmark's time-stepping algorithm. The impact of the projectile on the skull, as well as the collisions between flying fragments, are controlled through a nonsmooth contact algorithm. Cohesive theories of fracture, in conjunction with adaptive remeshing, control the nucleation and the propagation of fractures. The progressive opening of fracture surfaces is governed by a thermodynamically irreversible cohesive law embedded into cohesive-interface elements. Numerical results compare well with forensic data of actual firearm wounds to human crania.

Traits aren't blended! Cambridge opens a department of Genetics So What's it All About? It's about frequencies When talking about population genetics, we are interested in the prevalence of a particular allele or genotype in a population The Hardy-Weinberg Principle States: Frequencies of alleles and genotypes in a population will remain constant over time in the absence of other evolutionary influences Assumptions Organisms are diploid Generations are non-overlapping Population must be large No immigration or emigration No mutation in the gene of interest No natural selection occurs (individuals reproduce at equal rates) Mating is random Alleles and Allele Frequency Penguin Prof Helpful Hints The Sum of All Possible Outcomes MUST Equal 1 p+q = 1 ALLELE FREQUENCY 2 Alleles = Genotype p2 + 2pq + p2 = 1 What if There are Three Alleles? (p, q and r) Sample Problem In a population of 1,000 penguins, 12 have blue feet. Find the frequency of the blue allele, the yellow allele and the frequencies of the three possible genotypes in this population. Solving Hardy-Weinberg Problems Assign the alleles Frequency of the dominant allele is 'p' Frequency of the recessive allele is 'q' Calculate q by taking the square root of the number of homozygous recessive individuals Calculate p (the allele frequencies must equal 1, so p = 1 − q) Use p and q to calculate the other genotype frequencies: frequency of homozygous dominant individuals = p2 frequency of heterozygous individuals = 2pq frequency of homozygous recessives = q2 This may help: Hardy-Weinberg Punnett Square Try Another One...

The position vector 2. The velocity vector at launch and proceeds to calculate the orbital elements of the satellite's orbit. Namely: 1. Length of the Semi-Major Axis 2. Eccentricity 3. Inclination 4. Right Ascension of Ascending Node 5. Argument of Perigee 6. Initial Mean Anomaly after which it proceeds to show a visual animation of the orbit in 3D space, complete with the Earth's rotation,

Statistical network modeling via exchangeable interaction processes Part 2
 
32:33
Title: "Statistical network modeling via exchangeable interaction processes" Abstract: Many modern network datasets arise from processes of interactions in a population, such as phone calls, e-mail exchanges, co-authorships, and professional collaborations. In such interaction networks, the interactions comprise the fundamental statistical units, making a framework for interaction-labeled networks more appropriate for statistical analysis. In this talk, we present exchangeable interaction network models and explore their basic statistical properties. These models allow for sparsity and power law degree distributions, both of which are widely observed empirical network properties. I will start by presenting the Hollywood model, which is computationally tractable, admits a clear interpretation, exhibits good theoretical properties, and performs reasonably well in estimation and prediction. In many settings, the series of interactions are structured. E-mail exchanges, for example, have a single sender and potentially multiple receivers. I will introduce hierarchical exchangeable interaction models for the study of structured interaction networks. In particular, I will introduce the Enron model as a canonical example, which partially pools information via a latent, shared population-level distribution. A detailed simulation study and supporting theoretical analysis provide clear model interpretation, and establish global power-law degree distributions. A computationally tractable Gibbs sampling algorithm is derived. Inference will be shown on the Enron e-mail dataset. I will end with a discussion of how to perform posterior predictive checks on interaction data. Using these proposed checks, I will show that the model fits the data well.
INTEGRATED: Electromagnetic & Particle Trajectory Simulation Software

http://www.integratedsoft.com/ Our philosophy is in our name. Our CAE software programs are seamlessly integrated with each other. In many cases, models are affected by a combination of variables rather than just the electromagnetic or particle trajectory field. Where a combination of factors is involved, thermal and power systems design analysis may also be required. INTEGRATED offers an innovative, world-class suite of thermal and power systems design analysis tools for solutions involving multiple variables.
