Arduino Microcontrollers In The Classroom: Teaching How To Phrase Effective Science Questions And How To Answer Them With Original Data, Tony Dinsmore

Science and Engineering Saturday Seminars

Arduino microcontrollers in the classroom: teaching how to phrase effective science questions and how to answer them with original data. Prof. Tony Dinsmore, UMass Physics This workshop will develop course modules that address a challenge in the science curriculum: how do we teach basic problem-solving and curiosity-based research skills in a classroom setting? The standard science curriculum teaches concepts and theory quite well but leaves rather little opportunity for students to take the lead in designing and implementing their own investigations. The workshop will use the Arduino, an inexpensive microcontroller that is simple to set up. A huge range of ...

Fostering Computational Thinking In An Introductory Physics Lab, Diana Sachmpazidi Sep 2019

Fostering Computational Thinking In An Introductory Physics Lab, Diana Sachmpazidi

STEM Instructional Graduate Teaching Assistant Posters

•Thinking computationally means conceptualizing a problem and formulating it in a way that a computer can solve it (Wing, 2010). •Computational Thinking (CT) is the third pillar of the scientific method along with theory and experimentation and is a fundamental skill that K-12 students and undergraduates should be equipped with (Wing, 2016; 2006). •Research on CT has only been active the last 10 years and most studies are still at the stage of ideas (Kalelioglu et al., 2016). •The integration of CT aspects in instruction is a widely expanding phenomenon in physics classrooms in the context of higher education, and ...


Autonomous Watercraft Simulation And Programming, Nicholas J. Savino Apr 2019

Autonomous Watercraft Simulation And Programming, Nicholas J. Savino

Student Scholar Showcase

Automation of various modes of transportation is thought to make travel more safe and efficient. Over the past several decades, advances to semi-autonomous and autonomous vehicles have led to advanced autopilot systems on planes and boats, and an increasing popularity of self-driving cars. We predicted the motion of an autonomous vehicle using simulations in Python. The simulation models the motion of a small scale watercraft, which can then be built and programmed using an Arduino Microcontroller. We examined different control methods for a simulated rescue craft to reach a target. We also examined the effects of different factors, such as ...

Computational Techniques For Scattering Amplitudes, Juliano A. Everett Dec 2018

Computational Techniques For Scattering Amplitudes, Juliano A. Everett

Publications and Research

Scattering amplitudes in quantum field theory can be described as the probability of a scattering process to happen within a high energy particle interaction, as well as a bridge between experimental measurements and the prediction of the theory.

In this research project, we explore the Standard Model of Particle Theory, it’s representation in terms of Feynman diagrams and the algebraic formulas associated with each combination.

Using the FeynArts program as a tool for generating Feynman diagrams, we evaluate the expressions of a set of physical processes, and explain why these techniques become necessary to achieve this goal.


Comparative Study Of Qubits, Juliano A. Everett, Mubinjon Satymov, Zechariah Ilmot May 2018

Comparative Study Of Qubits, Juliano A. Everett, Mubinjon Satymov, Zechariah Ilmot

Publications and Research

In quantum computing, a quantum bit ("qubit") is a unit of quantum information. A qubit is a two-level quantum system. The developing of qubits with optimal properties, related to quantum entanglement and possibilities of control the states of qubits, is very important for quantum computing applications. We analyzed various types of qubits. There are at least five major quantum computing approaches being explored worldwide: silicon spin qubits, ion traps, superconducting loops, diamond vacancies and topological qubits. We compared the advantages and disadvantages in the properties of all these qubits for applications for quantum computing. We analyzed possible strategies to improve ...


Characterization Of Magnetic Thin Films Using The Magneto Optic Kerr Effect, Nicholas J. Savino Apr 2018

Characterization Of Magnetic Thin Films Using The Magneto Optic Kerr Effect, Nicholas J. Savino

Student Scholar Showcase

Understanding magnetic properties of materials allows for advances in applications such as data storage. The Magneto-Optic Kerr Effect (MOKE) displays the reflective response a magnetic material has to a magnetic field. When polarized light reflects off of a magnetic material, the polarization orientation can change. The application of an external magnetic field can affect how much this polarization changes in a non-linear manner. Hysteresis loops are created when examining the relationship between intensity of the reflected light to the applied magnetic field provide information about magnetic properties of that material, such as the coercive field and field retention. Preliminary measurements ...

Topology Of Earth's Magnetic Shield, David Alan Smith Dec 2017

Topology Of Earth's Magnetic Shield, David Alan Smith

David Smith

The open-closed boundary (OCB) defines the region where geomagnetic field lines transition from being closed to open. Closed field lines have both foot points at or near Earth in opposing hemispheres. Open field lines have one foot point at Earth; the other maps to the interplanetary magnetic field (IMF). Charged particles are able to follow these open field lines into Earth's upper atmosphere. The OCB also defines the polar cap boundary. Being able to identify and track the OCB allows study of several components of the geomagnetic system. Among them are the electrodynamics of the geomagnetic field and the ...


Open/Closed Boundary And Energy Cutoff Latitude For Varying Dst Indices, David Alan Smith Dec 2017

Open/Closed Boundary And Energy Cutoff Latitude For Varying Dst Indices, David Alan Smith

David Smith

Polar Cap Absorption (PCA) events are triggered by highly-energized solar particles gaining
access to upper regions of Earth's atmosphere at high latitudes. One impact of these events is increased
absorption of high-frequency radio signal. Last year at this conference I presented a poster offering a
thorough review of high-frequency radio wave absorption. An important next step would be a better
understanding of which particles are more likely to gain access to Earth's upper atmosphere as well as
other conditions that could either prevent or allow this access. Hence, as a continuation of my research
of PCA events I ...


Searching For The Origins Of Matter, Joshua L. Barrow May 2017

Searching For The Origins Of Matter, Joshua L. Barrow

Andrews Research Conference

The big bang and inflation are experimentally confirmed by multitudes of astronomical observations, yet theoretical tension still exists upon a very important question: why is there something rather than nothing? In other words, why are there unequal amounts of matter and antimatter? Why did a supposedly initially symmetric state not annihilate perfectly?

The breaking of this symmetry has allowed for all of material existence--also known as baryogenesis, the prevalence of matter over antimatter--and yields the theoretical possibility of direct detection by observation of baryon number violating mechanisms, which have previously never been observed.

One such plausible mechanism can be found ...


Stacking 2d Materials, Michael Hernandez, John C. Mann Mar 2017

Stacking 2d Materials, Michael Hernandez, John C. Mann

Seaver College Research And Scholarly Achievement Symposium

Monolayer Transition Metal Dichalcogenides are atomically thin semi-conductors that are considered quasi 2D materials due to their extremely small thickness. It has been observed that atomically thin crystals exhibit different physical properties than their bulk counterparts due to quantum confinement effects. We are attempting discover new physical properties by developing a technique to stack two different monolayer crystals, MoS2 and MoSe2.


The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth Mar 2017

The Property Of Mass: An Interdisciplinary Metaphysical Investigation, Benjamin Hayworth

Student Research and Creative Activity Fair

The property of mass as used in the physical sciences is somewhat of a metaphysical conundrum. Not only has the definition of mass changed with various paradigm shifts in physics, but the powers belonging to the property have also varied. In my study, I begin by examining the historical context surrounding the term, including the changes to its definition. In doing so, it is revealed that various definitions of mass are used and circulated in general discussion, so a cogent criterion of identity is established by which each definition can be measured. After determining the distinctions between each mass term ...


Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks Mar 2017

Between-Day Reliability Activity Fluctuations In Young Adults At Baseline And 6-Months Follow-Up, Connor J. Wicks

Student Research and Creative Activity Fair

Human Daily Motor Activity (DMA) is characterized by complex temporal fluctuations and scale invariance. DMA is estimated from a time series composed of continuous amounts of activity recorded with the Actigraph GT9X monitor. The purpose of this study was to measure the complex temporal fluctuations in several young healthy adults over a 7-day period. After six months there was a follow-up of another 7-day period. Future collections will involve healthy older adults and adults with Parkinson’s disease. For the first phase of this study, 24 healthy young adults wore the monitor on their non-dominant hand for seven straight days ...

A Review Of High Frequency Radio Wave Absorption, David Alan Smith Dec 2016

A Review Of High Frequency Radio Wave Absorption, David Alan Smith

David Smith

Although the technology dates back nearly to Marconi and his wireless telegraph, the high-frequency (HF) radio spectrum continues to be a useful communications medium.  Since long-distance HF propagation depends on the ionosphere, HF propagation is subject to variations in ionospheric characteristics.  Chief among these characteristics is the density of free electrons.  The sun provides the energy required to ionize neutral atmospheric constituents.  Hence, the production and loss of free electrons is not constant.  Day/night variations as well as the ebb and flow of the 11-year solar cycle cause changes in the density of free electrons.  In addition, space weather ...


Preliminary Results From A Ground Based Magnetometer Rotation Table, Rachel Newman, April Gross, Jolene Johnson, Kaye Smith, Erick Agrimson, James Flaten Aug 2016

Preliminary Results From A Ground Based Magnetometer Rotation Table, Rachel Newman, April Gross, Jolene Johnson, Kaye Smith, Erick Agrimson, James Flaten

2017 Academic High Altitude Conference

Understanding high altitude balloon rotation is important for many types of scientific measurements, therefore, balloon and payload rotation is a continuing area of interest and research. In this work, we present results obtained from an Arduino logged magnetometer rotated on a ground based rotation table. This table allowed us to precisely rotate and locate the Arduino logged magnetometer. We compare the Arduino logged results with “known magnetic field orientation” using an AIM rocketry altimeter. This comparison allowed us to test the accuracy of our Arduino logged results and the sampling capabilities of our magnetometer system using different rotational speeds.


Thermal Analysis Of Borosilicate Glass For Its Biological Applications, Gregory Humble Apr 2016

Thermal Analysis Of Borosilicate Glass For Its Biological Applications, Gregory Humble

Symposium of Student Scholars

Borosilicate glass doped with varying wt% of cerium oxide is investigated for biological applications. Thermal studies of each formulation were conducted using an SDT Q600 differential scanning calorimeter. 30mg samples of 350 - 425 μm particle size of each type of glass were heated to 1200°C in order to obtain the glass transition, crystallization, and melting temperatures. Samples were then heated to 900°C at several heating rates, ranging from 2°C/min to 100°C/min, then compared against each other as well as against an undoped borosilicate glass.
