Innovative concepts in lightweight engineering for automotive and aerospace applications increasingly trust in Multi-Material-Design. Additionally metal-plastic-combinations are often used in white or brown goods as well as within the furniture industry or in novel architecture concepts. A special challenge for multi material designs is the joining process. Existing technologies to join metals to polymers, like adhesive bonding or mechanical fastening, are ineffective regarding process time (adhesive bonding) or don’t applicate the forces optimally into the material (riveting, bolting). Moreover those technologies use supplemental materials like glue or rivets, which add weight and costs to the construction. The newly developed HPCI® (HeatPressCool-Integrative) tool appears like a spot resistance welding gun, which is widely used in car body engineering for metal ...

BACKGROUND:

Every year thousands of people lose body parts in accidents caused by different ways. Usually most of the other parts which are used to interact with computer are lost, but the eyes are still working, so why don't we use them? It doesn't mean if he or she doesn't have hands or he or she can't speak, and just because of this issue, he/she will go to bed and sleep the rest of their life. Why don't we find a way to allow their work to be carried out in the same way they used to do? For this purpose we figured that eyes are one of the biggest blessing we take for granted. We are trying to ...

An agreement has been reached between scientists that mercury exposure today is so high in many areas of the globe that it threatens human health. Mercury compounds have carcinogenic, mutagenic and teratogenic properties. Therefore, the Minamata Convention to limit anthropogenic mercury emission was signed in 2013 and ratified in 2017. To limit the anthropogenic mercury emission will be significant for creating a cleaner atmosphere in the future.

Coal combustion in coal-fired power plant is one of the main sources of anthropogenic mercury emission around the world, and the mercury released into the atmosphere with the flue gas emission. In the coal-fired flue gas, elemental mercury, Hg(0), is difficult to be controlled due to its high volatility and low solubility. ...

BRAILLE II implements a cheap, simple and portable multi-line Braille display compatible with any touch screen device, allowing low-income blind users to get access to education, public services and work opportunities easier than ever.

The device implements a mechanism that can generate Braille symbols and automatically slide them across user's finger, imitating the tactile feedback they would get reading ordinary Braille text. User's other hand is used to navigate across the surface of the screen of, let's say, a tablet. Said tablet reads touch coordinates and transmits a corresponding letter to BRAILLE II which is subsequently displayed to the user. Any graphical or console interface can be made available in Braille just by sending corresponding symbol commands to BRAILLE ...

The recent advances in state estimation, perception, and navigation algorithms have significantly contributed to the ubiquitous use of quadrotors for inspection, mapping, and aerial imaging. To further increase the versatility of quadrotors, recent works investigated the use of an adaptive morphology, which consists of modifying the shape of the vehicle during flight to suit a specific task or environment. However, these works either increase the complexity of the platform or decrease its controllability.

In this work, we propose a novel, simpler, yet effective morphing design for quadrotors consisting of a frame with four independently rotating arms that fold around the main frame. To guarantee stable flight at all times, we exploit an optimal control strategy that adapts on the ...

Environmental contaminants like total petroleum hydrocarbons (TPH), polycyclic aromatic hydrocarbons (PAH), and polychlorinated biphenyls (PCB) persist for decades in soils and sediments, and have been linked to cancer, immune and nervous system disorders, reproductive and developmental abnormalities, learning disorders, birth defects, and other health concerns. Traditional remediation methods are expensive and can further damage the environment. The estimated cost of remediating contaminated sites was estimated at $6-$8 billion annually in the U.S. and $425-$500 billion globally, mostly for remediating soils. Current cleanup methods include soil dredging, soil capping, and excavation. Dredging and/or excavating to remove contaminants is expensive, time consuming, and labor intensive, and risks harmful secondary effects such as damage to the ecosystem and the release of carbon ...

We introduce a low-cost pipette tip-based ELISA platform “ELISA in a Tip” as a next generation assay tool with lower cost, better sensitivity, shorter time, low sample and reagent volumes than traditional ELISA. Our platform could serve as a simple microfluidic adaptor that encourages to blend microfluidic advancement, multiplexing and smartphone integration with widely practiced gold standard ELISA without need for major overhaul of current infrastructure in hospitals and testing laboratories.

Pipette-tip adapters represent the first engineering advancement in decades-old well established diagnostic technique "ELISA." Tips were produced using a desktop 3D printer and were designed to fit most commercially available bench-top pipettes. Unlike ELISA which require extensive training and specialized technicians, pipette-tip ELISA users needs to know basic ...

SueChef is the first fully automated, start-to-finish, meal preparation solution and smart kitchen ecosystem. The SueChef itself, a multi-meal cold food storage and oven combination, removes the human element from cooking (and even the premises) by taking food from cold storage and putting it in the oven. This automated process is what makes SueChef such a leap from currently available smart cooking appliances, which focus on ease-of-use rather than transforming the food preparation paradigm altogether.

SueChef is the Keurig of food and just like Keurig, the SueChef has a proprietary K-cup equivalent, the SueTrée. The SueTrée is carefully designed to fit the form factor of SueChef, provide cooking data to SueChef upon load, easily transition from cold to hot without ...

Enriching work efficiency and rate of production, reducing production costs and workload, refining services and customer relations, maintaining security on a vast scale are a few of the top reasons why the Unmanned Aerial Vehicles (UAVs) industry is promising.

To gain an insight, in consequence of the continuous population growth- Egypt leads its way towards sustainability through the investment in its vast territories. In a world free of UAVs technologies, quality assurance imposes the existence of a complex infrastructure, powered by thousands of employees who will be in charge of observing these landscapes, collecting data, examining the overall conditions, predicting potential crisis and acting upon which - if any occurred. On such a large-scale project, a lot of workload ...

Someone in the US has a stroke every 40 seconds (nearly 800,000 strokes per year) and stroke is a leading cause of long-term disability. When brain damage occurs after a stroke, it can disrupt the nerve messaging between the brain and muscles, causing paralysis. People who suffer a stroke often experience arm and hand paralysis, which can lead to a loss of independence if they cannot adequately care for themselves, and result in the need for long-term care either at home or in a nursing home.

The approaches to coping with and restoring lost hand function can include using physical rehabilitation, braces, assistive devices, and hand exercise devices. A supportive brace helps with weakness and preventing painful muscle cramps, ...
