Staff Matters: How Much Time Off Should I Give For Bereavement?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

Author Jodi Schafer provides guidance for dental practices on developing clear and consistent bereavement leave policies. She notes that while no federal law requires bereavement leave, standard employer practice typically offers three to five days for immediate family members. The article emphasizes balancing compassion for grieving employees with the operational needs of the practice. Key considerations include whether leave is paid, the definition of covered relationships, and the importance of flexibility, as grief often extends beyond a formal leave period.

“I Didn’T Know Architects Do This”: Interventions In The Social Reproduction Of The Architect Figure In Ireland., Miriam Delaney

Doctoral

The architect is widely understood as the producer of architectural artefacts: buildings, feasibility studies, drawings, and specifications. However, architects (as a professional collective identity) are themselves produced by the complex matrix of social relations and structural forces in which they act; the architect is as much a product as the architectural artefacts.

This thesis provides a retrospective critical examination of aspects of my work in expanded forms of architectural practice from 2011 to 2021. My Critical Appraisal of this work focuses less on the content or successes of the Outputs, the products of production, and more on their collective contribution …

De Astronomiā: A Comparison Of Kepler’S Epitome Astronomiae Copernicanae And Ancient Astronomical Literature, Jillian Lees Darcy

Classics Undergraduate Senior Theses

My thesis is part translation and part analysis. I chose to translate an early modern astronomical text written in Neo-Latin and analyze this text through ancient writing on astronomy and cosmology. I chose to translate Kepler’s Epitome Astronomiae Copernicanae because of the many ancient allusions he makes in the introduction. While this text is valued for its scientific content and contributions, but I was interested in Kepler’s literary strategies, specifically how he engages in authorial self-fashioning, and how classical strategies of knowledge construction are distorted or mirrored in their style and content.  After my translation, I will analyze Kepler’s literary …

Wildlife Tracking Via Uav&Rf, Nam Ah Nguyen

Electrical Engineering

Animal tracking collars transmit very-high-frequency (VHF) beacon signals so researchers can locate tagged wildlife in terrain where direct visual tracking is difficult. This project develops a radio-frequency (RF) wildlife tracking prototype in which a UAV carries a receiving antenna and receiver over the search area to detect the collar signal and send measurements to a ground station. A transmitter test device was built to emulate a tracking collar. An STM32 microcontroller reads keypad input, controls a digital-to-analog converter (DAC), tunes a voltage-controlled oscillator (VCO) to the selected VHF frequency, and sends the RF signal through an amplifier and antenna. The …

Vlsi Spike Encoder For Spiking Neural Networks With 4-Bit Sar Adc, Jack Marshall, Wyatt Tack, Cameron Young, Ryken Thompson

Electrical Engineering

A spike encoder forms the interface between sampled data, such as image data or a sensor signal, and a spiking neural network by converting numerical input samples into discrete spike events. Unlike conventional artificial neural networks, spiking neural networks use spare, even-driven computation instead of continuous-valued activations. This makes them attractive for low-power embedded systems, biomedical electronics, and other edge applications where energy consumption, physical area, and thermal limits are important design constraints.

This project develops a modular spike encoder architecture for spiking neural networks with selectable support for temporal, rate, multi-spike, and delta encoding. Prior work has shown that …

Update: Colorado River Basin Storage Continues Slide Toward System Crash, Anne Castle, Jack Schmidt, Eric Kuhn, Kathryn Sorensen, Katherine Tara

The Traveling Wilburys of the Colorado River

If the Colorado River Basin (Basin) experiences another dry year, similar to Water Year 2025, it is likely that reasonably accessible storage in Lake Powell and Lake Mead would be mostly depleted, even if consumptive uses and losses are at or near historic lows. Run-of-the-river operations would shortly ensue. This would be an outcome with devastating consequences. In contrast, if next year is very wet, similar to Water Year 2023, the Basin’s largest federal reservoirs would recover somewhat, but would provide only about two years of cushion before we find ourselves again in the same position we are in today, …

Characterizing Aging-Induced Rowhammer Vulnerability And Designing A Runtime-Adaptive Defense For Ddr4 Dram, Abdulaziz Alajmi

Electrical and Computer Engineering Master's Theses

Rowhammer is a hardware fault that began as a DRAM reliability concern and became a security vulnerability. Repeatedly activating one row corrupts data in its neighbors, so an attacker who can hammer rows next to sensitive memory can flip bits they could never directly access. The number of activations needed to do so is called the Rowhammer threshold. The Rowhammer threshold has fallen steadily with each generation. The defenses that ship in response, from in-DRAM target-row refresh to the counter-based mitigations now mandated by the DDR5 standard, all rest on a quiet assumption: that this threshold is a fixed property …
