Heat Transfer Simulation in Materials Processing

Thermal processes are often used to create materials with specific mechanical and physical properties for use in advanced product designs in many industries including medical products, automobiles, and aerospace. Gases or liquids are typically used to heat or cool materials via conjugate heat transfer. In this webinar, we will demonstrate the use of COMSOL Multiphysics to investigate the effect of fluid flow rate on the quenching of a hot component. Conjugate heat transfer can occur via conduction, convection and even radiation in the case of high processing temperatures and therefore represents a full-featured heat transfer and CFD application requiring multiphysics analysis for accurate simulation. A Q&A session will take place at the conclusion of the webinar.

Mastering Distributed Control with Fully Integrated Systems

Large multi-axis or multi-process machines often benefit from additional controllers operating local processes while a main controller coordinates the efforts for the entire machine. In these cases, the additional controllers may need enough processing power to handle multi-axis motion as well as localized I/O.

Good Data Gone Bad-Why it is important to recognize bad engineering data before using it for durability and performance analysis.

Collecting good time series data is not a trivial task. This presentation will shed some light on causes and examples of bad data, and what separates good data from bad data. We will explain ways to recognize bad data, and suggest best testing and analysis practices to ensure the best possible engineering decisions are being made.

Rob Mueller, Lead Senior Technologist, Kennedy Space Center, FL

Rob Mueller is the Lead Senior Technologist for the RASSOR (Regolith Advanced Surface Systems Operations Robot) project, as well as all Kennedy Space Center (KSC) Human Robotics Systems. The RASSOR mining robot will collect soil (known as regolith) on the moon or Mars so it can be processed into rocket propellants, breathable air, water, and other consumable commodities as well as manufacturing and construction materials feed stocks.

Effects of Medical Sterilization on Optical Fibers

Optical fibers are successfully used in various areas of medicine, including urology, general surgery, ophthalmology, cardiology, endoscopy, dentistry and medical sensing. Prior to use inside a human body the fiber must be sterilized. Many types of treatments are known as effective sterilization techniques. OFS studied the effects of three sterilization conditions on optical fiber: multiple autoclaving, treatment with ethylene oxide, and treatment with gamma rays. Dr. Andrei A. Stolov will discuss these effects on key optical and mechanical properties of the fibers. Presenter Dr. Andrei Stolov Coatings Scientist OFS View the Tech Talk here.

Reducing Engineering Error and Design Disruptions: Exploring Calculation Software Tools

Performing and understanding calculations is a core responsibility of engineers across every discipline. These detailed calculations impact the beginning stages of design to determine if new concepts are feasible, at the middle stage of design to smooth out the finer details of products and to help with part assembly, and when designs are mature for verification and validation purposes.

Increased Spatial Resolution Lidars and 3D Robotic Vision

The Lunar Orbiting Laser Altimeter (LOLA) on the Lunar Reconnaissance Orbiter (LRO) launched in 2009 was NASA's first multi-beam lidar. LOLA has produced unprecedented topographic maps of the Lunar surface. LOLA used a Diffractive Optical Element (DOE) to produce five beams from a single laser for enhanced topographic spatial resolution.
