Description
This thesis details the design process of a variable gain amplifier (VGA) based circuit which maintains a consistent output power over a wide range of input power signals. This effect is achieved by using power detection circuitry to adjust the gain of the VGA based on the current input power so that it is amplifier to a set power level. The paper details the theory behind this solutions as well as the design process which includes both simulations and physical testing of the actual circuit. It also analyses results of these tests and gives suggestions as to what could be done to further improve the design. The VGA based constant output power solution was designed as a section of a larger circuit which was developed as part of a senior capstone project, which is also briefly described in the paper.

Description
Social media today is a major source of not only communication, but also news and entertainment. This year, people everywhere have had to embrace virtual environments as their main sources of communication. For students, especially, the move to virtual schoolwork in 2020 has increased the amount of time spent on technology. This observational study examined, through an anonymous online survey, how college students spend their time on social media and how it affects their mental health. The 25-question survey was open to current ASU students as of 2021, and 2020 ASU graduates. Respondents’ results concluded that while students actively use social media for communication and entertainment, it can present a burden on their mental health and their productivity.

Description
While SPICE circuit simulation software gives researchers and industry accurate information regarding the behavior and characteristics of circuits, the auditory effect of SPICE circuit simulation on audio circuits is not well documented. This project takes a thoroughly analyzed and popular audio effect circuit called the Ibanez Tubescreamer and simulates its distortion effect on a .wav file in order to hear the effect of SPICE simulation. Specifically, the TS-808 schematic is drawn in the SPICE program LTSPICE and simulated using generated sinusoids and recorded .wav files. Specific components are imported using .MODEL and .SUBCKT to accurately represent the diodes, bipolar transistors, op amps, and other components in order to hear how each component affects the response. Various transient responses are extracted as .wav files and assembled as figures in order to characterize the result of the circuit on the input. Once the actual circuit is built and debugged, all of the same transient analysis is applied and then compared to the SPICE simulation figures gathered in the digital simulation. These results are then compared along with a subjective hearing test of the digital simulation and analog circuit in order to test the validity of the SPICE simulations. The digital simulations reveal that the distortion follows the signature characteristics of Ibanez Tubescreamer which shows that SPICE simulation will give insight into the real effects of audio circuits modeled in SPICE programs. Diodes--such as Silicon, Germanium, Zener, Red LEDs and Blue LEDs--can dramatically change the waveforms and sound of the inputs within the circuit where as the Op-amps--such as the JRC4558, TL072, and NE5532--have little to no effect on the waveforms and subjective effects on the output .wav files. After building the circuit and hearing the difference between the analog circuit and digital simulation, the differences between the two are apparent but very similar in nature--proving that the SPICE simulation can give meaningful insight into the sound of the actual analog circuit. Some of the differences can be explained by the variance of equipment and environment used in recording and playback. Since this project did not use high fidelity audio recording equipment and consistency in the equipment used for playback, it is uncertain if the simulation and actual circuit could be classified as completely accurate. Any further work on the project would be recording and playing back in a constant environment and looking into a wider range of specific components instead of looking into one permutation.

Description
Objectives: To explore the feasibility and effects of using a meditation mobile app 10-minutes a day for 4-weeks to reduce burnout (primary outcome), improve mindfulness, reduce stress, and depression in physician assistant (PA) students compared to a wait-list control.
Methods: This study was a randomized, wait-list, control trial with assessments at baseline and post-intervention (week 4). Participants were asked to meditate using Calm for 10 minutes per day. A p value ≤0.05 was considered statistically significant.
Results: The majority of participants (n=19) stated using Calm helped them cope with the stress of PA school. The intervention group participated in meditation for an average of 76 minutes/week. There were significant differences in all outcomes for the intervention group (all p ≤0.06). There was a significant interaction between group and time factors in emotional exhaustion (p=.016) and depersonalization (p=.025).
Conclusions: Calm is a feasible way to reduce burnout in PA students. Our findings provide information that can be applied to the design of future studies.

Description
The rates of anxiety, depression, and attempted suicide for transgender individuals are extremely elevated relative to the general population. Yet, little research has been conducted about the transgender population regarding social transition (an individual presenting as their authentic/true gender, one different than the gender they were assigned at birth, in the context of everyday life) and parental acceptance. Both of which have been shown to impact the mental health of transgender individuals. The purposes of this study were: (1) To characterize a sample of transgender adults on their age of awareness of their authentic gender identity and their age of social transition. (2) Examine whether age of social transition, (3) parental acceptance, and (4) the gap in time between age of awareness and age of social transition (awareness-transition gap) were related to mental health. (5) Examine whether parental acceptance was related to age of social transition or to awareness-transition gap. (6) Examine whether age of social transition or awareness-transition gap interact with parental acceptance as correlates of mental health. The sample consisted of 115 transgender adults, ages 18 to 64. Measures were separated into 7 subheadings: demographics, transgender
on-cisgender identity, age of awareness, age of social transition, primary caregiver acceptance, secondary caregiver acceptance, and mental health. Hypotheses were partially supported for age of social transition with mental health, parental acceptance with mental health, and awareness-transition gap with parental acceptance. This study investigated under studied concepts of social transition and parental acceptance that appear to have an effect on the mental health of transgender adults.

Description
Introduction: This research examined the prevalence of Chinese older adults’ risk factors (perceived racial discrimination, fear of COVID-19), protective factors (resilience, community support), and mental health status (depression, PTSD) in Chinese older adults aged 65 years and above during the COVID-19 pandemic. Furthermore, the relationships between risk and protective factors and their mental health outcomes were explored.
Methods: This study was a secondary data analysis using the anonymous survey data collected by a research team. Descriptive statistics were used to describe the distributions of the variables; and hierarchical multiple regression models were conducted to examine their relationships.
Results: The sample included 90 Chinese older adults in the United States. The participants demonstrated a moderate level of fear of COVID-19 (M= 21.55, SD = 4.75; range 10-33). The participants scored on the lower end of the perceived discrimination scale (M = .40, SD = 1.44 before COVID-19; M = .77, SD = 1.54 during COVID-19; range 0-7). Resilience (M = 29.02, SD = 5.78 on a scale of 0-40) demonstrated a moderate to moderately high level of resilience. As for community support, 40.3% of participants reported receiving assistance or information regarding COVID-19 from local Asian organizations, indicating a moderate level of community support. The participants reported a relatively low score for PTSD (M = 0.75 SD = 1.17 on a scale from 0 to 5) or depression (M = 2.76 SD = 2.72 on a scale from 0 to 27). Consistent with hypotheses, findings of hierarchical regression models suggested that the risk factors fear of COVID-19 and perceived racial discrimination were positively associated with PTSD symptoms while resilience was negatively associated with PTSD symptoms. Differently, none of the risk factors were significantly associated with depression symptoms while resilience showed a negative relationship with depression symptoms.
Conclusion: The findings of this research will help public health officials better understand the needs of minority and aging communities to best support them during crises similar to the COVID-19 pandemic.

Description
The COVID-19 pandemic has notably affected the mental health of preadolescents, worsening issues such as depression due to reduced social interactions and increased online activity. "Twisted," a virtual reality (VR) game, integrates Cognitive Behavioral Therapy (CBT) principles to address these issues by helping players identify, and challenge distorted thoughts caused by cognitive distortions. This thesis explores the effectiveness of using VR to enhance the therapeutic potential of game-based interventions. The game encourages players to engage in cognitive restructuring through interactive scenarios, potentially offering a more immersive and effective alternative to traditional therapeutic methods for preadolescents. The research supports the game's ability to improve mental health outcomes by allowing repetitive practice of cognitive skills in a controlled, and engaging environment.

Description
The thesis explores the avenues of machine learning principles in object detection using TensorFlow 2 Object Detection API Libraries for implementation. Integrating object detection capabilities into ESP-32 cameras can enhance functionality in the capstone dragster application and potential applications, such as autonomous robots. The research implements the TensorFlow 2 Object Detection API, a widely used framework for training and deploying object detection models. By leveraging the pre-trained models available in the API, the system can detect a wide range of objects with high accuracy and speed. Fine-tuning these models using a custom dataset allows us to enhance their performance in detecting specific objects of interest. Experiments to identify strengths and weaknesses of each model's implementation before and after training using similar images were evaluated The thesis also explores the potential limitations and challenges of deploying object detection on real-time ESP-32 cameras, such as limited computational resources, costs, and power constraints. The results obtained from the experiments demonstrate the feasibility and effectiveness of implementing object detection on ESP-32 cameras using the TensorFlow2 Object Detection API. The system achieves satisfactory accuracy and real-time processing capabilities, making it suitable for various practical applications. Overall, this thesis provides a foundation for further advancements and optimizations in the integration of object detection capabilities into small, low-power devices such as ESP-32 cameras and a crossroad to explore its applicability for other image-capturing and processing devices in industrial, automotive, and defense sectors of industry.

Description
This study explores the correlation between personality types and internal monologues. Utilizing causal research survey data, a multinomial logistic regression was employed. Findings reveal a significant correlation between personality types and internal monologue types (positive or negative). However, other predicted factors did not yield significant results. Additionally, this regression yielded a low coefficient of determination, leaving room for improvement in the model. These insights contribute to understanding the intricate details of the human mind, providing implications for mental health interventions and therapy practices.
