Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do not provide any information about important cell ...

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...
Lifescan Scotland is a medical device company that designs and manufactures blood glucose monitoring kits for the global diabetes market. These involve the self-monitoring of blood glucose levels through specialized monitoring systems and test strips that comprise of a plastic substrate, two carbon-based electrodes, a thin dry reagent layer, and a capillary volume where the blood is placed. ...

In many medical procedures and tests, it is necessary to isolate cells of interest for further analysis. Microfluidics has revolutionized the way in which these tests are conducted enabling, for example, the ability to detect cancer from a blood sample. One of the most promising microfluidic techniques to separate and concentrate cells is called inertial focusing. The equilibrium positions for ...

High-power laser beam welding uses a localized heat source to achieve narrow deep welds and high welding rates. Engineers run into some difficulties because the use of a localized heat source often results in the distortion of metal components; spattering and the ejection of droplets from the weld pool results in underfills, undercuts, craters, blowholes, or blowouts. A stationary magnetic ...

Modern cars offer a wide range of complex functionality that comes with several design challenges. This story discusses some of the necessary updates to a roof module in a premium car and the charging system of an electric car. The roof module of a particular model houses several components. 90% of the generated heat goes into its printed circuit board (PCB), so temperature control is vital for ...

Radiation therapy targeting in cancer treatment involves many uncertainties, including the movement of targeted sites due to breathing and the like. Magnetic resonance imaging (MRI) can accurately identify the location of a tumor in soft tissue, but unfortunately its magnetic field can interfere with radiation treatment delivered by a linear particle accelerator (Linac). A team of researchers at ...

Professor Mark Reed and his team at Yale University are using COMSOL Multiphysics to develop a MEMS-based solution for detecting bacteria in blood. Called the aScreen, it will provide analyses speedily, accurately, and cost-effectively. Such a device would greatly help the food industry in improving meat quality and reducing the risk for infections. Current methods take too long for most food ...

This is an application brief describing the concept of Conjugate Heat Transfer, which is important in many industrial processes, such as quenching. In this brief, they simulate the heat transfer with and without phase transformation to analyze the rate of heat dissipation with respect to the flow conditions of the coolant media. The fluid flow conditions could then be modified to produce a ...
