Hello, my name is Fatima Ikhmais. I am a student in the Department of Architectural Technology. We all know that at the present time we rely heavily on electricity to heat and cool buildings, thus consuming a lot of energy and air pollution that leads to climate change. The aim of this project is to research, study, analyze and integrate passive cooling and heating strategies used by man in ancient times in contemporary architecture. This study focuses on the integration of passive cooling and heating strategies in the design and construction of buildings in the climatic conditions of New York City. Thus, reducing energy consumption and providing a healthy and comfortable environment for people.

We explore genetics in this project. More specifically, we analyze how physical features and characteristics are passed down through generations. We are mostly focused on recessive inheritance. In this situation, a recessive gene is only expressed when the organism has two recessive variations for that gene. In this case, one mutated gene is inherited from each parent. This means that both parents carry one mutated gene and one normal gene for the disease, without having the disease. We go through this form of inheritance and how the parent’s genes are passed down to their children. We develop matrix models that predict children’s set of genes as a function of their parents’ set of genes, and we use them to monitor the distribution of genotypes, or the collection of genes in a population, through generations. The possibility of inheriting a characteristic when it runs in the family is determined by looking at the various features passed down from the mother and father to the offspring.

The goal of my project is to study the female population growth based on their age. We use the Leslie Matrix Model to study the dynamics of this growth, which depends on the initial age distribution vector. We consider several initial vectors to see how they influence the future female population. The method depends on the calculation of powers of the Leslie matrix. We use an open-source mathematical software system called SageMath to perform the computations.

The purpose of this project was to investigate the structure and function of TTHERM 00287920, a member of the T. thermophila family, using computational techniques. TTHERM 00287920 was chosen, and a Blastp search was performed using NCBI BLAST to determine which human calpains TTHERM 00287920 was most similar to. A graphic representation of the blast protein sequence was also useful in determining whether human calpains are unrelated to TTHERM 00287920. MUSCLE, MAFFT, T-COFFE, and MEGA were used to analyze the similarity between the selected proteins using multiple sequence alignment techniques. Phylogenetic analysis was done using Phylogeny.Fr and Molecular Evolutionary Genetics Analysis (MEGA). Results from these tools suggest TTHERM_OO287920 is closely related to 7, 10 and 15. To streamline the human calpain that TTHERM_OO287920 is more closely related to, SWISS-MODEL, PHYRE2 and VMD tools were used. Analysis using these tools confirmed TTHERM_00287920 to be more closely related to human calpain 7 compared to the others.

Our project focuses on time spent in Open Lab and its correlation to the grades that Radiologic Imaging students receive on their practical’s. Open Lab is the time provided by the school, outside of the regular school hours for students to practice and try to enhance their positioning skills and help them grasp didactic concepts. These skills they develop not only help them for the practical’s but also help them while they are at clinicals. We distributed unbiased Google Surveys to the Juniors and the Seniors in the major. We also obtained longitudinal data from out mentor. Then we compared all the data that was collected. We obtained some very interesting data and there were some interesting correlations made!

The purpose of this investigation is to compare the amount of dose absorbed using a Phillips digital radiography x-ray machine VS a Pascal dosimeter and if the collimation on a larger body part reduces dose at a higher percentage than a smaller body part. Collimation was increased by 1-inch length and width for each exposure of the hand and lumbar spine. With collimation increased, the exposure field decreased meaning less dose to the body parts. Different dose absorption was observed in the DR machine vs the pascal dosimeter. DR machine decreased dose consistently and on pascal dosimeter dose first increased then drastically decreased, once the dosimeter was out of the light field. The lumbar spine decreased dose at 29% and the hand at 14% on the DR machine. On the dosimeter, lumbar spine dose decreased 6% and for the hand increased 214%. This research is useful in radiation protection practices and demonstrates that collimating can decrease dose.

This project is about using math to produce art. We follow a systematic procedure to understand how Bézier curves are constructed.  Then we use an open-source drawing program called Krita, which has a pen tool based on Bézier curves. This tool can be used to trace over images and create a piece of art. We discuss some strategies to reproduce a picture by selecting certain control points that are used to define a Bézier curve.

Hi, my name is Wilna Michel and I want to talk to you about the exciting world of publishing. Over the Fall 2021 semester, I was given the opportunity to view the world of Publishing from within with my mentor Professor Sara Woolley. We prepared the sketches and turned them into digital files ready for line Development and color Application. At the end of all these steps, we have created a piece of art ready to be seen by everyone. Upon finishing that we organized the pages in the book format and added text.
