Aerial Reconnaissance – University of Missouri College of Engineering

The Missouri Department of Conservation’s Andy Raedeke worked with this image during a waterfowl survey of the Swan Lake National Wildlife Refuge near Sumner, Missouri. Currently, when the Missouri Department of Conservation (MDC) wants to keep track of the waterfowl population in the state or monitor wetlands for invasive plant species, they send a natural resource manager into the field to do a manual count, which is very labor intensive and not very accurate. Other methods to monitor bird populations…

Determining the Best Option for NVMe-over-Fabrics

Non-volatile memory express (NVMe) presents a streamlined means for delivering low-latency operation, and it’s being adopted by all major server and storage vendors (see figure). The architecture is replacing Small Computer System Interface (SCSI) in modern solid-state-disk (SSD) resources. As a result of its adoption, NVMe-enabled SSDs are now eliminating the bottlenecks that were inherent in traditional storage implementations—leading to substantial improvements in the access speeds for a range of applications from mobile platforms to enterprise data centers. This article…

System achieves new level of efficiency in harnessing sunlight to make fresh potable water from seawater — ScienceDaily

A completely passive solar-powered desalination system developed by researchers at MIT and in China could provide more than 1.5 gallons of fresh drinking water per hour for every square meter of solar collecting area. Such systems could potentially serve off-grid arid coastal areas to provide an efficient, low-cost water source. The system uses multiple layers of flat solar evaporators and condensers, lined up in a vertical array and topped with transparent aerogel insulation. It is described in a paper appearing…

Pressure is on to Recruit the Next Generation

The inability to attract and retain talent is a top concern for manufacturers. That’s the refrain manufacturers have preached for years, and according to a report prepared by Deloitte and The Manufacturing Institute, an estimated 2.4 million manufacturing jobs could go unfilled by 2028. What’s behind the shortfall? The short answer: a significant skills gap. The opportunities are being created faster than employers can fill them, say the experts, despite an estimated $26.2 billion spend in 2019 on internal and external training…

Composites Improve Machine Tool Structures

When it comes to designing the moving structural elements of high-performance machine tools—such as beams, shafts and spindles, and the assemblies used to hold cutting tools—the need for the machine tool to be accurate, consistent and durable translates into being built of parts that are light, strong, and stiff. Whichever material a designer selects, the physical requirements call for hollow section members with thin walls. Thin-walled hollow structures have the stiffness and low weight, but they can have other characteristics…

Improving Business and Customer Experience using Natural Language Processing

Do you remember a familiar voice over the phone saying “This call may be monitored for training and quality purposes”? Well, this is quite an acquainted encounter when we call customer care service of any company. Moreover, these calls are recorded for training but the data is actually gathered to improve automated services to customers by improving natural language processing algorithms. Natural language processing is assisting businesses to descend meaning from the uncountable unstructured data available online and in call-logs.…

Fluid Intelligence | Machine Design

As part of Machine Design’s 90th anniversary issue in January, we’ve asked industry experts to take a look at the present and future of technology and how it will impact the design and operation of manufacturing over the next decade. Q: What products do you see that are currently solving design engineers’ problems? Mathews: We’ve seen consumer products make giant leaps in functionality thanks to the use of modular, optimized hardware defined by software (as is the case with smartphones…

Red alert as Arctic lands grow greener — ScienceDaily

New research techniques are being adopted by scientists tackling the most visible impact of climate change — the so-called greening of Arctic regions. The latest drone and satellite technology is helping an international team of researchers to better understand how the vast, treeless regions called the tundra is becoming greener. As Arctic summer temperatures warm, plants are responding. Snow is melting earlier and plants are coming into leaf sooner in spring. Tundra vegetation is spreading into new areas and where…

Medical Devices Drive the DC Motor Market

The blood brain barrier (BBB) in humans consists of blood vessels and tissues that regulate the passage of chemicals and other substances going from the bloodstream into the brain. It does a good job of keeping potentially harmful molecules from crossing over and affecting the central nervous system. The downside is that if clinicians need to treat a brain problem, such as toxic chemical exposure or a tumor, it’s difficult to get therapeutic drugs across that barrier to do their…

Find the Resolve to Resolve your Issues

Welcome to February! Everybody who is continuing to keep their New Year’s resolutions, please raise your hands. I’ll wait. (Pause.) Not too many hands there. Anyone else? Me, either. I had vowed to eat well, exercise frequently, stretch out my aging body and generally get myself in some kind of shape. After a month, I’m getting to the gym more, and I’m eating a little better, and I’m able to touch my toes, but I’d hardly call this effort a…
