Infill panels and partitions are widely used non-structural elements in reinforced concrete buildings, characterized by a significant seismic vulnerability as testified by disastrous collapses observed during recent earthquakes, for both in-plane and out-of-plane actions. The most advanced building codes foresee mandatory verifications of these elements, both when designing a new building and when assessing the seismic adequacy of an existing one. Moreover, recent evaluations have shown that, after low-intensity earthquakes, damage of non-structural parts strongly influences repair costs for typical multi-storey buildings. In this occasion an innovative concept for infill panels and partitions is presented, in which (either concrete ...
USDA's Economic Research Service (ERS) defines food waste as "the component of food loss that occurs when an edible item goes unconsumed, as in food discarded by retailers due to color or appearance and plate waste by consumers." Food waste includes the half-eaten meal left on the plate at a restaurant, food scraps from preparing a meal at home and the rotten milk a family pours down the drain.
To reduce the amount of this waste I present here a concept for a mobile Food Security App generation.
The Food Security App would be for individual mobile phones where ...

This project deals with the protection from advanced fire near the forest or fields, which inhibit the fire or extinguish it until the arrival of rescue forces.
The role of the system is to identify the fire that is approaching a certain area and accordingly activate the sprinkler system and fire warning.
There is currently no domestic systems to prevent large fires but there is a general regional system that can provide a partially solution for residents who live near forest areas or systems that their coverage is very small.
During the project I gathered information ...
The world will remain heavily dependent on fossil fuels such as oil, gas, and coal for the rest of this century for the purpose of power production. But if we don’t think about this then the day is not far where they all will be depleted. That’s is why the concept of extracting the free energy of the universe and to convert it to power to extend the lifetime of the system or to provide an endless power supply to the system has motivated many researchers towards this field.
In this developed system, we provide a new ...

This machine is based on gravity power and seesaw system. We can make it more simple.
As per sketch there will be two seesaw systems and both will be attached with a stand.This stand will work to hold the seesaw. There will a middle track (MIDDLE TRACK SEESAW) which will work a pathway to transport the object from one seesaw to another seesaw.
There will be two motors which will work to incline both sides of the seesaw systems by pushing the counter weight side of each seesaw.
When right side motor will work to push up the counter ...
Solar Transportation Technologies announces designs for a Solar Powered Nationwide Mass Transit system based on self-driving electric cars and high-speed weather proof toll roads.
The system is to be funded by Public / Private Partnership with a 30% government investment. In 15 years government tax revenue from the Nationwide Mass Transit system could top $315 billion annually with total gross annual revenue in excesses of $788 billion at 45% of total miles driven.
The Nationwide High-speed network is accessed via stations that ensure the vehicles are fit for high-speed travel. The toll road powers the electric cars from solar panels ...
This new technology has many applications, suitable for Linear electric motors, Electric Gear Box and Clutch or as an Electric Braking System. In the Electric Gear Box and Clutch, the backing plate that the energised coils are mounted onto can rotate, making it a floating clutch, while as an Electric Braking System, the backing plate that the energised coils are mounted onto, is fixed to the center axle and does not rotate. The energised coils react with the permanent magnets in the rotor to provide a means to provide high torque braking of the rotor using the forces of ...

Today the world's population continues to grow, so does the amount of garbage that people produce. Today's fast lifestyle requires easily disposable products as soda cans or bottles of water etc. The accumulation of these products has led to increased plastic pollution around the world. Plastic is composed of major toxic products has the potential to cause a great harm to the environment in the form of air & land pollution. Some plastics are manufactured from recycled material but their use in engineering tends to be limited because the consistency of formulate & their physical properties tend to be less ...

In recent years the cost of wind and solar generation has dropped precipitously resulting in exponential growth. Governments are now setting goals of 50%, 80% or even 100% renewable generation, but for these goals to be met one critical element is missing: low cost electricity storage.
The preeminent technology is pumped storage hydro (“PSH”), with over 150 gigawatts installed and more planned. However, increasing construction costs and siting constraints are restricting expansion. Batteries are effective in some applications, but far too expensive at PSH scale. Neither of these technologies can solve the storage dilemma.
The Gravity Power Plant (GPP) provides ...

Wave energy has huge capacity which needs to be explore more. In India, total capacity of Wave energy is 41 GW. As compared to wind, solar & hydel power, Wave has two challenges; it is not continuous & energy carrying media, i.e. water, doesn’t have a uni-directional motion. There are various techniques followed in harnessing wave energy which are solving one common challenge- “How to get continuous output of power from discrete wave power”. Predominantly there are two techniques followed; Pumping water from wave energy to a reservoir & releasing to continuous power generation. Second,generate electricity directly ...
