rying to get commercial truck drivers to accept an electric vehicle over the internal combustion engine that they've known for years will be a challenge, but not an impossible one.What it's going to take is getting more concept vehicles out there, and giving more people the opportunity to ride in these vehicles.

Cuts, scrapes, blisters, burns, splinters, and punctures there are a number of ways broken skin happens. Most treatments for skin wounds involve simply placing a barrier over them (usually an adhesive gauze bandage). This keeps it moist, limit pain, and reduces exposure to infectious microbes. A new, scalable approach to speeding up wound healing, developed based on heat-responsive hydrogels. Mechanically active, stretchy, tough, highly adhesive, and antimicrobial, active adhesive dressings (AADs). To close wounds significantly faster than other methods and prevent bacterial growth without additional apparatus or stimuli. https://glewengineering.com/engineers-add-new-updates-to-medical-advances-2019/ This technology has [...]

There are solar panels installed, not only on the roof but on each side as well, in total 334 square feet of thin-film solar panels which can deliver up to 3,000 watts of [...]
Though great on a hot day, an air conditioner is expensive, consumes a lot of energy, and often requires coolants that deplete ozone.
Alternatives for Polystyrene Foam, Made from petroleum, Styrofoam is used in everything from coffee cups, building materials and construction, transportation, and packaging industries. Made from toxic ingredients, depends on petroleum.
A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors, has shown promise in a clinical trial.
Wearable Brain Machine Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair. Interacting with a computer, or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires. This work reports fundamental strategies to design an ergonomic, portable EEG system for a broad range of assistive devices, smart home systems, and neuro-gaming interfaces. Not to mention, primary innovation is in the development of a fully integrated package of high-resolution EEG monitoring systems and circuits [...]
What does it mean for a species to become extinct? It means that those plants or animal have completely died out, and no longer exist on Earth.
Worldwide semiconductor revenue hit and all-time-record of $120.8B in Q2 2018, which represents an almost 4.5% quarter over quarter growth. More Integrated Circuits are being put into traditional products, such as enterprise data storage units and smart phones. Now cars, refrigerators, and a whole host of Internet of Things, are integrating chip sets into their products as well. Memory dominates chip production and usage, and has helped to keep Samsung in its leadership position. (Record Fab Spending) Samsung Remains the Number One Semiconductor Manufacturer Samsung posed Q218 revenue of $19.2B [...]
Fig. 1 A street bike shown in CAD mesh. Mechanical Engineering Consulting Group Evaluates 3D CAD Programs Mechanical Engineering Consulting Testing of Creo™, Solidworks™, and Inventor™ Mechanical Engineering Consulting service companies largely use one of three 3D CAD programs: Creo™, Solidworks™, and Inventor™. At Glew Engineering, we have licensed seats of all three CAD mechanical design packages. We reviewed the CAD workflow and feature sets of each 3D CAD program using motorcycle frame design as an example. Also, we showed that some of the specialized commands of each 3D CAD software programs [...]
Conduction and Radiation of Thermal Energy In my last blog post, I wrote about the conduction and radiation of thermal energy through windows and the thermal transmittance value, called the U-Factor, that characterizes that heat transfer. The U-factor is useful in evaluating window performance and making wise decisions when specifying components for a building, but it is only one piece of the puzzle. The National Fenestration Research Council (NFRC) mandates a second value alongside U-factor in its certification process, called the Solar Heat Gain Coefficient (SHGC). SHGC [...]

Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi. I’ve saved the best for last, however: Leonardo da Vinci. He is the quintessential renaissance man who fits both our running definition of “Italian Master” as well as being included in the standard list of Masters with Rafael, Donatello and Michelangelo Leonardo’s incredibly broad array of talents and interests have long been the subjects [...]
Italian Masters: Volta Jump-Starts Electrical EngineeringFigure 1: Girolamo Cardano (1501-1576) Welcome back to our series on Italian Masters of math and science. Last week I wrote about Galileo’s extensive accomplishments both in the field of astronomy and beyond. This week, I’ll take a look at another renaissance polymath who dabbled in astronomy, along with his work in mathematics, medicine, biology, chemistry, philosophy, and gambling (yes, seriously): Girolamo Cardano. Cardano is a less well-known figure than Galileo or some of the other scientists I’ve written about who have famous equations or units [...]
Portrait of Galileo Galilei Justus Sustermans [Public domain], via Wikimedia Commons I’d like to return to our previous series on the Italian Masters, focused not on the usual masters or painting and sculpture but on the masters or science, mathematics, and engineering. So far in the series I’ve written about the accomplishments of Volta, Cassini, Venturi and Torricelli. Today, I’d like to look at one of the greats: Galileo Galilei. Galileo is most famous today for standing up for heliocentrism against the Catholic Church and spending the last [...]
We'll continue on now with our blog series on finite element analysis (FEA). After discussing how to best set up a computer-aided design (CAD) model for FEA simulation, in this blog I'll cover the next step: meshing the model and applying boundary conditions. "Meshing" is the process by which the CAD model is separated into discrete finite elements; it can be done in the same program that runs the FEA numerical simulation later, or it might be performed in a standalone program, depending on your software. Boundary conditions are the loads (forces, [...]
Figure 1: Giovanni Battista Venturi [i] Glew's News is doing a short series highlighting the lives and accomplishments of the Italian Masters of science, engineering, and mathematics. In the last blog, I wrote about Evangelista Torricelli, a mathematician and physicist from the 17th century. In this blog, I'm focusing on Giovanni Venturi (Figure 1), an accomplished physicist, hydrodynamicist and engineer. Giovanni Battista Venturi (1746-1822) Giovanni Venturi was born to a wealthy family in Reggio, Italy in 1746. A talented young student, by the age of 23 the local seminary had [...]
Figure 1: Reinforced concrete mesh © Glew Engineering Consulting Welcome back to our blog series on FEA. In the last blog entry, we introduced some of the fundamental concepts in finite element analysis (FEA). This entry in the blog series focuses on the initial steps in preparing a computer-aided design (CAD) model ready for use in an FEA program. Since FEA programs are very sensitive to the data they have to work with, it's important that the CAD models being analyzed are compatible with the analysis methods the FEA program uses. In order to illustrate my points [...]
