This research explores the role of Computer Aided Design (CAD) software used to optimize the product design process prior to manufacturing. CAD software called SolidWorks simulates how a part will behave under a variety of engineering constraints.  These simulations are then used to optimize performance both of the part and the overall manufacturing process.  The software analyzes the constraints and suggest an optimized geometry of the part which may be converted to a finalized and validated redesign.

This project is about using math to produce art. We follow a systematic procedure to construct a curve known as This project is about using math to produce art. We follow a systematic procedure to construct a curve known as Bézier Curve.  Then we use an open-source drawing program, Krita, which has a pen tool based on Bézier Curves to draw art-like Picasso’s cubism paintings. The goal is to help people who do not know math or art and show them very easy ways to draw a nice artwork with the implicit use of math.

In a modern society, access to restrooms is a key indicator of human health and sanitation- yet 40% of the World’s population has limited access to it. Furthermore, over 800,000 deaths worldwide are attributed to inadequate sanitation. In developed countries, where flush based sanitation systems are a standard, there are fundamental questions being asked about the restrooms being connected to both the water supply system and the wastewater infrastructure. The purpose of this paper is to evaluate the downfalls of the flush based sanitation system, and to develop decentralized dry restroom systems which potentially use a significantly lesser amount of water and could potentially provide a value-added product in the form of either energy or fertilizers. Restrooms in remote regions are often expensive to connect to the twin-circulation system, and environmentally unsustainable. We plan to design systems using a biodigester with anaerobic bacteria to decompose the fecal matter into treated water, and methane, which could then be potentially used as a fuel source. This would be  expected to provide approximately 240KWh of energy for every metric tone of waste released in the restroom.

In bioinformatics, scientists have to analyze large amounts of data to find some meaningful information within it. They must also be able to share their analysis results in an organized and understanding way so others may support their findings. As a solution, scientists can use different computer programs for data analysis. Using Rstudios, scientists are able to analyze data using R code based file types such as R script, R markdown, R notebook, and R shiny. The project discusses the features and abilities of each file type, along with executed examples of how each file type may be used for data analysis in bioinformatics. The material constructing each of the executed file types was provided from previously completed lab activities from Bioinformatics II(BIO 3352L). These hands-on examples show how each file type may be useful and what their purpose may be when discovering and sharing information.

The purpose of my research project is to show the power of matrices to explore graphs related to airline route maps. Have you ever wondered how the airline companies show you the possible flight numbers in different ways that would get you from one place to another? This project is focused on finding the number of flight connections between seven cities in Hawaii by Hawaiian Airlines company using graph theory. At first, a directed graph from the route map is constructed and afterwards a matrix M is obtained from it. Then, using matrix powers, I observe the number of existing or non-existing direct flights in two steps between any two cities. Then I obtain another matrix S to find the airport hubs. This investigation is helpful to reduce the unnecessary cost of flights by finding the exact number of direct flights in the minimum number of steps between the cities.

The Leslie Matrix Model was developed to study population growth based on the age distribution over time. It is very popular around population ecology. To understand the dynamics of the growth process, we need to use advanced tools from Linear Algebra. The goal of this project is to understand the mathematics behind the results that indicate if the population is eventually increasing, decreasing, or if it is stabilizing.

Our goal was to design and create two mountings that would gratings of different sizes. We took the measurements of each grating and then used it to design two different structures that would hold each grating. After we finished the design process it was time to take our design to a mechanical engineer to bring it to life. The mechanical engineer collaborated with us to cut the cost of production and materials that we would use by suggesting that we make the top of the mounting adjustable and the bottom circular so that it would fit on a rotating stage.

According to the Glossary of Prosthodontics Terms, an obturator is a prosthesis used to close a congenital or an acquired tissue opening, primarily of the hard palate and/or contiguous alveolar structures. The aim of this project is to identify the ethical considerations, economic issues and to apply this knowledge in a real case. while in comparison on the knowledge learned before on the process of making a conventional denture. Obturator dentures can impact and help people with congenital defects, trauma and cancer. A maxillary defect it’s a problem that affect millions of people around the world and with a proper prosthesis we can change their lives.

Satellite-based remote sensing observations at different wavelengths and frequencies are used for various climate, environmental, meteorological, and water resources studies. Among different bands, infrared and microwave data are crucial for the retrieval of several atmospheric quantities related to land surface processes, to monitor vegetation phenology and surface properties, and for numerical weather prediction (NWP) data assimilation. Land surface emissivity which is related to the earth surface characteristics is derived from infrared land surface temperature (LST)microwave brightness temperature(TB)data. In this project, students are learning about both infrared data from Moderate Resolution Imaging Spectroradiometer (MODIS) and microwave data from Global Precipitation Measurement(GPM) Microwave Imager (GMI)at the global scale. Students are also engaging in downloading data from NASA website and processing them. So far, we have done the infrared part.
