Engineers Develop Drones to Protect Elephants from Poachers

2019-07-14T11:52:04-07:00

Herd of elephants bathing in the jungle river of Sri Lanka Drones have been used to ward off elephants from destroying crops because of their bee-like buzzing noise, they’re also being used to help the same animals from being hunted for their ivory in Africa. Since off-the-shelf UAVs can easily give pilots an aerial perspective, non-profit Mara Elephant Project (MEP) in Kenya started using drones to fight elephant poaching as far back as 2012.  How Have Drones Helped Curb Elephant Poaching? Drones are just one tool used by MEP Engineers, but they have [...]

Engineers Develop Personal Robots – New Age

2019-07-14T11:52:36-07:00

Engineers Say Personal Robotics Will Become an Important New Category in Family Lives  I have the idea of a “sociable” robot—one that people can have relatively natural interactions with—has been the lore of science fiction for decades. From Lost in Space to Star Wars to WallE and beyond, interactive robotic machines have been the stuff of our creative imagination for some time. In 2019, however, I believe we will start to see more practical implementations of personal robotics devices from several major tech vendors. While several companies have tried, and failed to [...]

Part 2: Self-driving Cars Expand the Fight Over Airwaves

2019-07-14T11:52:43-07:00

Engineers Say Public is Hungry for More Wi-Fi Capacity, the telecom industry is looking to snatch control of underutilized airwaves reserved for the auto industry. But this is coming just as carmakers begin to make progress on developing and adopting technologies for connected and autonomous cars that currently rely on that spectrum. The Big Picture: Tech and telecom companies have been fighting for years over spectrum to support exploding demand for mobile services and smartphones. Automakers have had exclusive access to a band of spectrum for almost 20 years [...]

Engineers Develop Ways to Ventilate Your Home

2019-07-14T11:53:02-07:00

Why ventilate? For centuries homes weren’t ventilated, and they did all right, didn’t they? Why do we need to go to all this effort (and often considerable expense) to ventilate houses today?  Engineers have developed several reasons that ventilation is more important today than it was long ago. Most importantly, houses 100 years ago were leaky. Usually they didn’t have insulation in the walls, so fresh air could easily enter through all the gaps, cracks, and holes in the building envelope., the building materials used 100 years ago were mostly natural [...]

Electric Vehicle Batteries: Recycled

  Material Scientist Ponder What to Do With Used EV Batteries  As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025.  This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements.  The price of cobalt has [...]

Samsung topples Intel as top dog semiconductor market share  Gartner beancounters say price rises driven by memory shortages propelled Samsung into the lead based on semiconductor vendor revenue, vaulting past Intel and its CPUs. The largest memory supplier, Samsung Electronics, gained the most semiconductor market share and took the No. 1 position from Intel – the first time Intel has been toppled since 1992. Memory accounted for more than two-thirds of all semiconductor revenue growth in 2017, and became the largest semiconductor category.  DRAM prices rose 44 per cent from 2016 [...]

Wind Load Calculations and Modeling

2018-02-20T12:26:27-07:00

 Part 1 of our Wind Load Series “Wind load” is a calculated value representing the total force on a structure or object cause by pressure from wind moving over it.  In this blog series, we will discuss different methods for wind load calculations, the factors that influence its magnitude, and the effects a high wind load can have on a structure.  Wind load is most commonly addressed by civil and structural engineers when designing buildings, but mechanical engineers can encounter the effect when designing tall objects like cranes, telescoping communications masts or [...]

Thermal Expansion in a Glass and Aluminum Window: Part 2

2018-02-20T13:29:14-07:00

Figure 1: Simplified model of an aluminum-glass window   In last week’s blog, Thermal Expansion in a Glass and Aluminum Window: Part 1, we introduced the basic concept of thermal expansion in solid materials.  Since CTE mismatch can impose extremely high stress, during mechanical engineering design one must consider the temperature exposure and expansion or contraction of a material.  In order to help the read gain insight, we used a simplified aluminum-framed window to demonstrate that a hot summer day would be enough to shatter glass [...]

Thermal Expansion in a Glass and Aluminum Window: Part 1

2018-02-21T10:38:23-07:00

Equipment designers must accommodate thermal expansion (CTE)of dissimilar materials, especially when they are subject to large temperature changes.  This problem is often called "CTE mismatch."  In this blog, we give the fundamentals of thermal expansion calculations used in thermo-mechanical analysis. These calculations are simple but useful, and easy enough to perform by hand or with a spread sheet. For more complicated shapes, one must use computer modeling.  As an example, we perform a finite element analysis (FEA) in a later blog http://glewengineering.com/thermal-expansion-in-a-glass-and-aluminum-window-part-2/, of a glass and aluminum window [...]
