NFX is a FEA generalist software committing to make your FEA work efficient and cost effective. Go achieve this goal, NFX carries 3 most distinguishable characteristics:
1) CAE/CFD solution-in-one interface: This makes NFX more multidisciplinary, and seriously saves your effort to switch between platforms.
2) Intuitive workflow and GUI: NFX is designed to carry out complicated tasks in headache-free ways. Consistent feedbacks about “fast learning curve” and “junior engineer friendly” make us confident to claim for the best in this one.
3) High-end analysis capacity with affordable price: provides total solutions from high-end structural analysis functions such as contact analysis, nonlinear analysis, explicit dynamic analysis and fatigue analysis in addition to high-end fluid analysis functions such as moving mesh, free surface analysis and mass transfer analysis.

Abstract:
The Modelica language, being standardized and equation-based, has proven valuable for the for model exchange, simulation and even for model validation applications in actual power systems. These important features have been now recognized by the European Network of Transmission System Operators, which have adopted the Modelica language for dynamic model exchange in the Common Grid Model Exchange Standard (v2.5, Annex F).
Following previous FP7 project results, within the ITEA 3 openCPS project, the presenters have continued the efforts of using the Modelica language for power system modeling and simulation, by developing and maintaining the OpenIPSL library: https://github.com/SmarTS-Lab/OpenIPSL
This seminar first gives an overview of the origins of the OpenIPSL and it’s models, it contrasts it against typical power system tools, and gives an introduction the OpenIPSL library. The new project features that help in the OpenIPSL maintenance (use of continuous integration, regression testing, documentation, etc.) are also described.
Finally, the seminar will present current work at LNLL that exploits OpenIPSL in coordination with other tools including ongoing work integrating openIPSL models into GridDyn an open-source power system simulation tool, as well as a demos of the use of openIPSL libraries in GridDyn.

The suite HyperWorks (HW) was introduced in a course of master degree in Mechanical Engineering. The course titled “Design of Production Processes” has the aim to develop a market-pull product in a set of steps beginning with a perception of a market opportunity and ending in production, sale and delivery activities. HW was used for linear static and non linear quasi static analyses to correctly size the different parts which make up the investigated product. The lessons were organized starting from a general overview on Finite Element Analyses, followed by an introduction to HW interface and, finally, the steps necessary to set-up and to analyze the results of different types of simulation were described. Furthermore, topology optimization of particular sub-components were performed by Inspire.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Car tires require sophisticated analysis because of their complex geometry, large
deformations, nonlinear material behavior, and varying contact conditions. Brick
elements are used to represent the tread and steel bead, while shell elements are
used in the wall area. Membrane elements are used to represent the tire cords.

This guitar features two strips of
graphite running the length of the

moisture content
changed.
Using the FEM calculations,

Future Trends in the FEM and Simulation
• The FEM in particular, and simulation in general, are becoming
integrated with the entire product development process (rather than just
another task in the product development process):
– FEM cannot become the bottleneck.
• A broader range of people are using the FEM:
– Not just hard-core analysts.
• Increased data sharing between analysis data sources (CAD, testing,
FEM software, ERM software.)
• FEM software is becoming easier to use:
– Improved GUIs, automeshers.
– Increased use of sophisticated shellscripts and “wizards.”
25. 25
Future Trends in the FEM and Simulation (cont.)
• Enhanced multiphysics capabilities are coming:
– Coupling between numerous physical phenomena.
» Ex: Fluid-structural interaction is the most common example.
» Ex: Semiconductor circuits, EMI and thermal buildup vary with current
densities.
• Improved life predictors, improved service estimations.
• Increasing use of non-deterministic analysis and design methods:
– Statistical modeling of material properties, tolerances, and anticipated loads.
– Sensitivity analyses.
• Faster and more powerful computer hardware. Massively parallel processing.
•Decreasing reliance on testing.
• FEM and simulation software available via Internet subscription.

Selected FEM Resources on the Internet
• The internet offers virtually unlimited resources to persons
interested in the FEM.
• The following links are a small sample of FEM sites on the
Internet which the author has found useful. Thousands more
(at least!) are readily available.
• Most commercial FEM developers have extensive presence
on the Internet, with web pages that include company
histories, descriptions of software products, and example FEM
solutions.
• Other good FEM resources on the web originate with
academia, government, and discussion and user groups.
