Android Drone: REMOTE QUADCOPTER CONTROL WITH A PHONE

The purpose of the “Android Drone” project was to create a quadcopter that can be controlled by user input sent over the phone’s Wi-Fi connection or 4G internet connection. Furthermore, the purpose was also to be able to receive live video feedback over the internet connection, thus making the drone an inexpensive option compared to other, equivalent drones that might cost thousands of dollars. Not only that, but the Android phone also has a host of other useful features that could be utilized by the drone: this includes GPS, pathing, picture taking, data storage, networking and TCP/IP, a Java software environment, and a large, diverse variety of Android software endpoints that allow for things like facial recognition or motion detection. Ultimately, this project was intended to give a cost effective means of adding hundreds of potential features to a standard quadcopter

Cal Poly Engineering PhotoBot: Final Design Review

The purpose of this project was to create a remotely controlled camera device; the PhotoBot captures images and videos of various plants and perhaps animals for biological analysis. The features for such a device allows a user to capture images and videos from various angles and heights with minimal outside assistance. Furthermore, the device is designed for users that do not wish to spend an extensive amount of time and effort taking pictures and videos in the rainforest. The key constraints of the device includes safety, versatility, ease of use, and durability. Ultimately, this project was completed for Dr. Cris Cristoffer as a senior project through the Mechanical Engineering Department at Cal Poly

Islamic Headcovering and Political Engagement: The Power of Social Networks

This article explores the relationship between headcovering and women’s political participation through an original online survey of 1,917 Muslim-American women. As a visible marker of religious group identity, wearing the headscarf can orient the integration of Muslim women into the American political system via its impact on the openness of their associational life. Our survey respondents who cover are more likely to form insular, strong ties with predominantly Muslim friend networks, which decreased their likelihood of voting and affiliating with a political party. Interestingly, frequency of mosque attendance across both covered and uncovered respondents is associated with a higher probability of political participation, an effect noted in other religious institutions in the United States. Yet, mosque attendance can simultaneously decrease the political engagement of congregants if they are steered into exclusively religious friend groups. This discovery reveals a tension within American Muslim religious life and elaborates on the role of religious institutions vs. social networks in politically mobilizing Muslim-Americans

The Complexity of Covering: The Religious, Social, and Political Dynamics of Islamic Practice in the United States

Mainstream American perception often views Islamic head covering as a controversial practice indicative of gender repression and norms violating individual rights. Practicing Muslims counter that head covering expresses piety, modesty, and protection. Recent scholarship affirms the complexity of the practice, and reveals that the motivations behind donning the headscarf span the religious, social, and political realms for Muslim women.Methods.We explore the motivations for the practice among American Muslims, examining the way religious, social, and political life interact and reinforce one another, using data from an online survey of 1,847 Muslim-American women from 49 states.Results.Our findings demonstrate that religiosity is not a monolithic factor, and religious practices interact with and enforce head covering in complex ways. We illustrate that conventionally understood indicators of Islamic religiosity align along three dimensions: religious lifestyle, religious abstinence, and religious socialization. Elements of a religious lifestyle, such as praying and attending mosque as well as fostering connections with Islamic social networks, are more strongly associated with covering than practices related to abstinence or socialization.Conclusions.Ultimately, our research demonstrates a more nuanced understanding of how different aspects of Muslim religiosity condition covering among Muslim-American women

A Methodology for Risk Assessment to Improve the Resilience and Sustainability of Critical Infrastructure with Case Studies from the United States Army

Reliable performance of energy and water infrastructure is central to the mission readiness of the United States Army. These systems are vulnerable to coordinated attacks from an adversary as well as disruption from natural events. The objectives of this work were to investigate Army installations in North America, identify best practices for improving the resilience and sustainability of critical energy and water infrastructure, and develop a framework and methodology for analyzing the resilience of an installation under varying outage scenarios. This work was accomplished using a multi-layered decision process to identify unique case studies from the 117 active-duty domestic Army installations. A framework for analyzing and assessing the resilience of an installation was then developed to help inform stakeholders. Metered energy and water data from buildings across Fort Benning, GA were curated to inform the modeling framework, including a discrete-event simulation of the supply and demand for energy and water on the installation using ProModel. This simulation was used to study the scale of solutions required to address outage events of varying frequency, duration, and magnitude, the combination of which is described as the severity of outages at a given site. This project helps develop a framework to inform how installations might meet Army Directive 2020-03, which states that installations must be able to sustain mission requirements for a minimum of 14 days after a disruption has occurred

Activity-dependent Golgi satellite formation in dendrites reshapes the neuronal surface glycoproteome

Activity-dependent Golgi satellite formation in dendrites reshapes the neuronal surface glycoproteome. Elife, 10, (2021): e68910, https://doi.org/10.7554/eLife.68910.Activity-driven changes in the neuronal surface glycoproteome are known to occur with synapse formation, plasticity, and related diseases, but their mechanistic basis and significance are unclear. Here, we observed that N-glycans on surface glycoproteins of dendrites shift from immature to mature forms containing sialic acid in response to increased neuronal activation. In exploring the basis of these N-glycosylation alterations, we discovered that they result from the growth and proliferation of Golgi satellites scattered throughout the dendrite. Golgi satellites that formed during neuronal excitation were in close association with endoplasmic reticulum (ER) exit sites and early endosomes and contained glycosylation machinery without the Golgi structural protein, GM130. They functioned as distal glycosylation stations in dendrites, terminally modifying sugars either on newly synthesized glycoproteins passing through the secretory pathway or on surface glycoproteins taken up from the endocytic pathway. These activities led to major changes in the dendritic surface of excited neurons, impacting binding and uptake of lectins, as well as causing functional changes in neurotransmitter receptors such as nicotinic acetylcholine receptors. Neural activity thus boosts the activity of the dendrite’s satellite micro-secretory system by redistributing Golgi enzymes involved in glycan modifications into peripheral Golgi satellites. This remodeling of the neuronal surface has potential significance for synaptic plasticity, addiction, and disease.This work was financially supported by NIH RO1 DA035430, DA044760, and DA043361 (WNG) R01 GM104010 (BSG), T32 GM007183 (FV), and Peter F McManus Foundation (WNG)

The developmental effects of media-ideal internalization and self-objectification processes on adolescents’ negative body-feelings, dietary restraint, and binge eating

Despite accumulated experimental evidence of the negative effects of exposure to media-idealized images, the degree to which body image, and eating related disturbances are caused by media portrayals of gendered beauty ideals remains controversial. On the basis of the most up-to-date meta-analysis of experimental studies indicating that media-idealized images have the most harmful and substantial impact on vulnerable individuals regardless of gender (i.e., “internalizers” and “self-objectifiers”), the current longitudinal study examined the direct and mediated links posited in objectification theory among media-ideal internalization, self-objectification, shame and anxiety surrounding the body and appearance, dietary restraint, and binge eating. Data collected from 685 adolescents aged between 14 and 15 at baseline (47 % males), who were interviewed and completed standardized measures annually over a 3-year period, were analyzed using a structural equation modeling approach. Results indicated that media-ideal internalization predicted later thinking and scrutinizing of one’s body from an external observer’s standpoint (or self-objectification), which then predicted later negative emotional experiences related to one’s body and appearance. In turn, these negative emotional experiences predicted subsequent dietary restraint and binge eating, and each of these core features of eating disorders influenced each other. Differences in the strength of these associations across gender were not observed, and all indirect effects were significant. The study provides valuable information about how the cultural values embodied by gendered beauty ideals negatively influence adolescents’ feelings, thoughts and behaviors regarding their own body, and on the complex processes involved in disordered eating. Practical implications are discussed
