We accumulate several cloud services on Amazon Web Services (AWS) into developing a serverless system in the cloud that replaces the current technical support request, which occurs via calls, in a classroom setting. The instructor can notify the so-called IT person with a press on the programmable Internet of Things (IoT) button. We plan to deploy the system at our university as a way for class instructors to request help without interrupting the lecture. The system is low-cost thanks to AWS's pay-as-you-go policy and easy to install.

The most viable path to alleviate the Global Climate Change is the substitution of fossil fuel power plants for the generation of electricity with renewable energy units. The substitution requires the development of very large (utility-level) energy storage capacity, with the inherent thermodynamic irreversibility of the storage-recovery process. Currently the world also experiences a significant growth in the numbers of electric vehicles, which use very large batteries. A fleet of electric vehicles is equivalent to a relatively efficient storage capacity that may be used to supplement the energy storage system of the electricity grid. Calculations based on the demand-supply data of a large electricity grid show that, even though a fleet of electric vehicles cannot provide all the needed capacity for a large electricity grid, the superior round-trip storage efficiency of batteries significantly reduces the energy dissipation associated with the storage and recovery processes. A very small amount of battery storage significantly reduces the dissipated energy in the electricity grid. Also, improvements in the round-trip efficiencies of batteries are three times more effective than improvements in hydrogen storage systems.

The dryer is a steel cylinder, approximately 36 inches in diameter and five feet in length. The cylinder also spins at a rate up to 10 rpm. The inside surface contains 48 lifters. These lifters have two variants and are made of mild steel. They are designed to move limestone through the cylinder while the cylinder spins.

The drying of limestone is usually done industrially in a rotary drum dryer. The purpose of this project is to generate a model that will predict limestone particle motion as it passes through the dryer.  By creating an accurate model of the particle movement during the drying cycle, the operator will be able increase the dryer’s efficiency.  Using basic physics and through experimental testing, our team was able to produce a model that will provide detail of particle motion inside the dryer.

The Mississippi River Delta is the 7th largest river delta on Earth that consists of the Mississippi River and the Gulf of Mexico. Additionally, it contains 40% of the wetlands in the contiguous United States and over two million hectares (4,942,108 acres), an area equivalent to the size of two football fields, of agricultural lands. Due to fertilizer runoff from agricultural lands, the river delta has been experienced excess levels of nitrogen and phosphorus. The excess levels of these nutrients have contributed to water pollution in the delta and the hypoxia zone in the Gulf of Mexico. This research will focus on mapping the levels of nitrogen and phosphorous across the river delta to determine where the highest levels are
