Using Degeneracy Breaking to Design a MEMS Biosensor
In the paper “Degeneracy Breaking, Modal Symmetry and MEMS Biosensors”, which was presented at the COMSOL Conference 2013 in Rotterdam, researchers experiment with using material and geometric symmetry breaking to design a MEMS biosensor.
Green Energy Management for Communication Systems
The communication network wasn’t designed to carry the amount of traffic that is currently transmitted around the world on a daily basis. With the rapid expansion in data traffic and the exponential growth in high-speed communications, the current network is coming under increasing strain. At Bell Labs, researchers are looking into ways to improve energy efficiency through the use of optimized electronics cooling and energy harvesting technology. Two new energy-savings approaches developed by the group promise significant savings.
Thermal Contact Resistance Simulation
How does thermal contact resistance affect heat transfer? As the sizes of electronic devices continue to decrease, effective heat management becomes even more important. Today, electronic packaging has transitioned from its original purpose of providing mechanical protection and interconnection to also serving as a means of heat dissipation to the outside environment. Using a model from the Model Gallery, we explore the role of thermal contact resistance on heat management in a simple electronic package and heat sink assembly.
Accurate Hematology Analysis Using Hydrofocusing
Hematology analysis is an important step in medical diagnoses, often determining the treatment that a patient will receive. With a patient’s life on the line, it is vital that these analyses are accurate to the highest degree possible. Researchers at HORIBA Medical, a worldwide supplier of medical diagnostic equipment, turned to simulation to develop new methods for optimizing the accuracy of their hematology analysis devices. The resulting technique is currently used in some of their best-selling equipment.
What Is a Packed Bed Reactor?
The chemical industry is considerably important to economies around the world, playing a critical role in processes ranging from the production of clean drinking water to the manufacture of pharmaceutical products. Chemical engineers are faced with the challenge of ensuring profitability in a rapidly growing and evolving market. Packed bed reactors are one of the most common reactors used in the chemical industry due to their high conversion rate per catalyst weight compared to other catalytic reactors.
Solving a Space Problem with Origami Principles
Engineers designing space-bound satellites and solar arrays face a rather ironic challenge — lack of space. In order to overcome this problem, aerospace engineers are turning to an interesting source for inspiration: origami, the ancient art of Japanese paper folding.
Optimizing the Continuous Casting Process with Simulation
The Swiss steel company SMS Concast has been leveraging multiphysics simulation to optimize the steelmaking process of continuous casting. Through research conducted using COMSOL Multiphysics, the R&D team at SMS Concast was able to implement a new technique that allowed a steelmaking plant in Taiwan to reduce yearly CO2 emissions by about 40,000 tons.
Just Published: Paper on Modeling Spinal Column Stimulation
In the 2012 edition of Multiphysics Simulation, we featured an article about modeling spinal cord stimulation to determine the effect that scar tissue can have on electrical current distribution during the treatment of chronic pain. Recently, the full-length paper by Beth Israel Deaconess researchers Jeffrey Arle, Kris Carlson, Longzhi Mei, and Jay Shils was published in the journal Neuromodulation.
