A retractable LCD monitor for use in aircraft and the like is supplied with power from a power supply that is secured in a fixed off-monitor location on the monitor’s housing. The power supply also provides power for a motor assembly that controls a pivoting of the monitor between open and retracted positions. This configuration allows for a…[Leggi tutto]

Solar street lighting is a unique opportunity for sustainable recovery

In response to the economic fallout from COVID-19, the European Union has formulated a major recovery plan for the continent with a key focus on adapting to the digital age and investing in cleaner and more resilient technologies for the future. In the U.S., the 2021 American…[Leggi tutto]

On the Move: Unpacking the Challenges and Opportunities of Electric Vehicles

SINGAPORE – More than 600 electric vehicle (EV) chargers will be installed at some 200 public carparks in HDB estates, industrial estates and the Central Business District over the next 12 months.

The first of these car chargers are expected to be installed by the end…[Leggi tutto]

The trajectory of prices of the five volume commodity PVC resin powder was upward through September; but starting last month, a reversal was underway for most of these resins, possibly excepting PE and PVC. Factors in the continued flat-to-downward trajectory for PP, PS and PET included expectations of improved supply availability, lower feedstock…[Leggi tutto]

An integrated circuit is a semiconductor wafer on which thousands or millions of tiny resistors, capacitors, and transistors are fabricated. Sometimes called a chip or microchip. The invention of the integrated circuit made technologies of the Information Age feasible. ICs are now used extensively in all walks of life, from cars to toasters to…[Leggi tutto]

Now here’s a cool idea: a metal box that helps your food last longer! Have you ever stopped to think how a refrigerator keeps cool, calm, and collected even in the blistering heat of summer? Food goes bad because bacteria breed inside it. But bacteria grow less quickly at lower temperatures, so the cooler you can keep food, the longer it will…[Leggi tutto]

In some batch filtration processes, highly permeable suspensions dewater fast compared to the rest of the process. This work explores the impact of fast-filtering compressible materials on the throughput of fixed-chamber filter presses. The dewatering properties for a compressible yet highly permeable minerals processing slurry are used as inputs…[Leggi tutto]

When a hydraulic pump operates, it performs two functions. First, its mechanical action creates a vacuum at the pump inlet which allows atmospheric pressure to force liquid from the reservoir into the inlet line to the pump. Second, its mechanical action delivers this liquid to the pump outlet and forces it into the hydraulic system.

A pump…[Leggi tutto]

Three-phase motors (also annotated numerically as 3-phase motors) are widely used in industry and have become the workhorse of many mechanical and electromechanical systems because of their relative simplicity, proven reliability, and long service life. Three-phase motors are one example of a type of induction motor, also known as an asynchronous…[Leggi tutto]

This paper is about the development of an expert system for automatic classification of granite tiles through computer vision. We discuss issues and possible solutions related to image acquisition, robustness against noise factors, extraction of visual features and classification, with particular focus on the last two. In the experiments we…[Leggi tutto]

The kids have only been in school for two months, but the papers and artwork are piling up. Normally I keep a select pieces of artwork and recycle the rest (after the kids are in bed). This year I’m taking a different approach. Armed with my Straight Talk Samsung Galaxy S6, I’m taking pictures of their artwork and turning it into a kids art scr…[Leggi tutto]

In this article, we present two methods for calculation of the inductance of toroidal core power inductors wound by rectangular cross-sectional wire, considering that the current density is inversely proportional to the circular coil radius. The first method is to simplify the helical toroidal coil into a thick-walled toroidal, and based on…[Leggi tutto]

We propose the I3* indicator as a non-parametric alternative to the journal impact factor (JIF) and h-index. We apply I3* to more than 10,000 journals. The results can be compared with other journal metrics. I3* is a promising variant within the general scheme of non-parametric I3 indicators introduced previously: I3* provides a single metric…[Leggi tutto]

It is clear that packaging plays a large role in the perceived value of a product and as a whole, the packaging industry really hasn’t changed too much in the past years, compared to the constant innovations made in portable technology. With all the packaging and Color Box choices available in today’s market, it often becomes difficult to sel…[Leggi tutto]
