Pyscan: Interfacing Laboratory Instruments With Python, Julian N. Payne, Peter E. Timperman
18th Annual Celebration of Undergraduate Research and Creative Activity (2019)
Laboratory instruments can be interfaced with and controlled from personal computers. Several programs to scan lasers and acquire data have been written by students in the Polik Lab. However, computer hardware and software change more rapidly (3-5 years) than instrument lifetime (20 years). Thus, programs must be replaced to run on modern computers and operating systems. This can be done to minimize dependence on specific hardware and software. PyScan is a laser instrument interface program intended to replace the Polik Lab’s current software. It allows the user to control the laser, setup a scan, acquire data, and store the data …

Graphics Processing Units (Gpus) And Cuda, Josiah Brett, Josiah Brouwer
18th Annual Celebration of Undergraduate Research and Creative Activity (2019)
Computers almost always contain one or more central processing units (CPU), each of which processes information sequentially. While having multiple CPUs allow a computer to run several tasks in parallel, many computers also have a graphics processing unit (GPU) which contains hundreds to thousands of cores that allow it to execute many computations in parallel. In order to complete a larger task, GPUs run many subtasks concurrently. Each core performs the same instruction on different sets of data, making it useful for performing tasks such as calculating what each individual pixel displays on a screen. The purpose of this research …

Unmanned Aerial Vehicles (UAVs) are receiving an increasing attention from the research and industry community, and today they are adopted for several civilian and military applications. However, state of the art technologies is still based on a single UAV either directly controlled by the human operator or supervised through the manual definition of a flight plan. As a result, scalability is still a significant limitation for such systems, especially when large areas need to be monitored. In this paper we propose a web-based application for the control of multiple UAVs. The application has three layers. The first layer allows the …
