  3. Every year high volumes of hazardous organic pollutants, such as long-chain petroleum hydrocarbon, contaminate aquatic and soil ecosystems. This occurs because heavy compounds are less prone to natural weathering processes such as, volatilization, biodegradation, and dissolution. Furthermore, these pollutants harm the environment, animals, and huma...

  4. Electrospinning is a fiber production method that uses electricity to draw charged threads of polymer solutions into fiber diameters. This technique is used in a variety of water purification applications. Current water purification applications use a post-treatment on the electrospun fibers in order to create pores that catch impurities. If the po...

  5. Radiotherapy is a common medical procedure, especially for the treatment of cancers such as head and neck, breast prostate, lung and rectum. It is a complex process aimed at maximizing delivery of the planned dose to the tumor sites while minimizing unnecessary radiation to healthy tissues. Today, radiotherapy procedures make use of image guidance ...

  6. With the ever-expanding need for renewable energy sources growing, much time and energy is allocated to finding new and innovative technologies. Current membrane reactors focus on a specific class of photocatalyst or are limited to air purification only. This approach does not take into consideration a broader range of the electromagnetic spectrum,...

  7. Spatial changes during building construction usually manifest as deviations between the as-designed model and the as-built conditions. These deviations can lead to errors that result in delays and additional costs. Project engineers often spend significant time, money, and resources to manually track and analyze changes between the as-designed mode...

  10. Traffic signal control systems are inefficient for simulating traffic and constrain both research and development. Proposed traffic control systems require high computing power or physical replacement of hardware, which results in high manufacturing costs. Therefore, there is a need for a centralized traffic control system that quickly simulates tr...
