Applying Visual Identity At The Main Entrances To Cities (Case Study: Entrance To Beni Suef City), Nesma Mohamed Abd El- Maksoud

Mansoura Engineering Journal

Egypt’s vision and many initiatives, such as the “Controlling Egyptian Urbanism and Supporting Visual Identity” initiative, seek to create a visual identity for Egypt’s governorates, to deepen the concept of national belonging, and to issue a guideline for visual identity at the level of each governorate. The visual identity of cities is produced from a set of urban, social, cultural, historical, and environmental variables. Economically, the research studies how to link the urban and visual identity of cities and express it through the entrances to cities and the urban spaces surrounding them to improve and develop the city’s local and …

Vision-Language Integration For Enhanced Locomotion Mode Prediction, Ehsan Ahmadi

LSU Master's Theses

Wearable exoskeletons offer significant potential in enhancing human mobility in industrial environments. However, their adaptability to dynamic, task-intensive settings presents challenges, especially in accurately predicting locomotion modes such as ladder climbing, stair navigation, low-space movement, and obstacle navigation. This research proposes a multimodal framework that integrates visual data and speech commands to improve locomotion mode prediction in unpredictable environments. Multimodal data was collected using smart glasses, capturing both the user’s perspective (field-of-view, FOV) and voice during locomotion tasks. State-of-the-art models—CLIP, ImageBind, and GPT-4o—process these visual and linguistic inputs to predict locomotion activities. The models were evaluated in zero-shot and fine-tuned …

Preservice Elementary Teachers’ Perceptions Of The Incorporation Of An Ecojustice Framework In An Undergraduate Stem Integration Course, Rita G. Ortiz

USF Tampa Graduate Theses and Dissertations

Environmental education across the K-12 science curriculum lacks critical examination of human and ecological relationships, particularly in relation to science, technology, engineering, and mathematics (STEM) education. While the Next Generation Science Standards include environmental topics within their disciplinary core ideas and many schools offer environmental science courses, this gap can be addressed in teacher preparation programs, particularly for those teaching younger students. Ecojustice centers on socioecological topics by addressing cultural assumptions we, as humans, live by in relation to natural systems. Ecojustice education is a critical pedagogy that engages learners about social issues related to our current ecological crisis. This …

Dynamic And Harmonic Studies Of Inverter Based Resources, Rabi Shankar Kar

USF Tampa Graduate Theses and Dissertations

As the inverter-based generation is the primary technology driving renewable energy sources such as solar photovoltaic and wind turbines, its penetration is increasing rapidly. Due to the high penetration, there are multiple situations of IBR misoperation due to any type of grid contingency. This dissertation focuses on exploring the response of IBR towards grid contingency.

The primary objectives of the study are as follows: 1. Conducting a harmonic analysis of inverter-based resources when subjected to balanced and unbalanced grid conditions, 2. The use of a circuit simplification method to streamline the analysis process and study the dynamic response of IBR …

The Vietnam War was an inescapable part of life for Americans in the 1960s. This thesis serves to tell the story of one Arkansas boy’s life who serves as a microcosm of the American boys sent overseas to fight in a war that they largely did not understand. The information within the project is drawn from primary source materials collected by the Jacksonville Museum of Military History and the possessions of John Wayne Acosta sent home from Vietnam. Secondary sources serve to complement the class and personal struggles John Wayne had to deal with in volunteering and then re-upping to …

Synthesis And Characterization Of Titanium And Vanadium Nitride–Carbon Composites, Helia Magali Morales, David A. Sanchez, Elizabeth M. Fletes, Michael Odlyzko, Victoria Padilla, Mataz Alcoutlabi, Jason Parsons

Mechanical Engineering Faculty Publications

Titanium nitride and vanadium nitride–carbon-based composite systems, TiN/C and VN/C, were prepared using a new synthesis method based on the thermal decomposition of titanyl tetraphenyl porphyrin (TiOTPP) and vanadyl tetraphenyl porphyrin (VOTPP), respectively. The structure of the TiN/C and VN/C composite materials, as well as their precursors, were characterized using Fourier Transformed Infrared Spectroscopy, X-Ray diffraction (XRD), X-Ray energy dispersive (EDS) and X-Ray photoelectron spectroscopy (XPS). Morphologies of the TiN/C and VN/C composites were examined by means of scanning electron (SEM) and transmission electron (TEM) microscopy. The synthesis of the non-metalated tetraphenyl porphyrin, the titanium, and vanadium tetraphenyl porphyrin complexes …

Lengthening Atlantic Hurricane Seasons With Earlier Storm Formation Dates Including Implications From 2020, Barry D. Keim, L. C. Hamilton, V. M. Brown, P. J. Klotzbach, A. B. Lewis, D. T. Thompson

School of Public Health Faculty Publications

This paper analyzes the formation dates of the nth storm in a sequence for all named North Atlantic tropical cyclones (TCs) and assesses whether the intraseasonal length of the Atlantic hurricane season has changed temporally. The record-breaking 2020 season, with 30 named storms, set records for the earliest third TC formation (Cristobal) and from the sixth TC (Fay) onward. Analysis of season length from 1851 to 2022 identifies only one statistically significant breakpoint detected in the early 1970s, roughly coinciding with the introduction of satellite observations. Since 1970, we also find a trend toward longer North Atlantic hurricane seasons. The …

Hybrid Energy Systems: Synergy Margin And Control Co-Design, Mario Garcia Sanz

Faculty Scholarship

Extraordinary properties emerge from subsystems' interactions. Hybrid energy systems (HESs) are a promising concept that could change the renewable energy landscape. By co-designing generation, storage, and conversion technologies, HESs can provide new electrical power services, increase grid stability and control authority, and generate energy and/or nonenergy products such as electricity, hydrogen, ammonia, heat, digital data, or fresh water. This article discusses some conditions the co-design of HESs should follow to optimize the combined system (synergy), avoiding deterioration (dysfunction). It introduces some technoeconomic synergy conditions, develops a synergy margin, and analyses several case studies, exploring also the control co-design methodology to …

Korea, Germany, And The Arsenal Of Democracy, Michael Fitzpatrick

The US Army War College Quarterly: Parameters

In the 1970s, the United States and West Germany developed a vital transatlantic partnership focused on new military doctrines and technology that met the challenges of the late Cold War. Due to domestic politics and strategic concerns, the United States never recreated this type of relationship with countries in the Indo-Pacific region—specifically with South Korea. Using a unique synthesis of American, German, and Korean sources, this article argues that another partnership is required in Asia today. Rather than fall back on European partners, Washington should collaborate with Seoul to develop a new generation of doctrine and technology.

Development Of Long-Term Studies Evaluating The Potential Of Chondrostereum Purpureum As A Mycobiocontrol On Invasive Buckthorn, Abraham F. Stone

Michigan Tech Undergraduate Scholarship

Chondrostereum purpureum is a circumboreal polypore with high potential as a native fungal biocontrol for weedy, deciduous tree species in the Northern Hemisphere. This thesis describes the development of three multi-year studies designed to evaluate the effectiveness of C. purpureum as a management tool for invasive buckthorn (Rhamnus cathartica and Frangula alnus) in Upper Michigan, in a manner that tests a broader range of application methods beyond girdling or cut-stump treatments. Our experiments focused on a) developing a viable liquid inoculum to spray on buckthorn whips and b) creating a symptomatic assessment scale to quantify disease progression of C. purpureum …

Structural, Thermal, And Optical Spectroscopic Studies Of Sm3+-Doped Ba2znsi2o7 Phosphors For Optical Thermometry Applications, None Tejas, A. Princy, S. Masilla Moses Kennedy, Vikash Mishra

Open Access archive

Samarium-doped Ba2ZnSi2O7 orange red-emitting phosphors for novel applications in temperature measurement were prepared by a solid-state synthesis method. A Ba2ZnSi2O7 akermanite-structured Sm³⁺ phosphor was allocated to the C2/c space group and monoclinic system. Using FTIR, identification of different bonds with their vibrational modes has been done. Stimulated at 403 nm, the as-prepared phosphors show yellow (560 nm), orange (600 and 645 nm), and red (705 nm) emissions, which were also used to maximize the dopant concentration. Sm³⁺ ions may be uniformly dispersed throughout the Ba2ZnSi2O7 matrix, and Sm³⁺ consists of irregular microparticles. Optical energy bandgap values for …

Phagolysosomes Break Down The Membrane Of A Non-Apoptotic Corpse Independent Of Macroautophagy, Shruti Kolli, Cassidy J. Kline, Kimya M. Rad, Ann M. Wehman

Biological Sciences: Faculty Scholarship

Cell corpses must be cleared in an efficient manner to maintain tissue homeostasis and regulate immune responses. Ubiquitin-like Atg8/LC3 family proteins promote the degradation of membranes and internal cargo during both macroautophagy and corpse clearance, raising the question how macroautophagy contributes to corpse clearance. Studying the clearance of non-apoptotic dying polar bodies in Caenorhabditis elegans embryos, we show that the LC3 ortholog LGG-2 is enriched inside the polar body phagolysosome independent of autophagosome formation. We demonstrate that ATG-16.1 and ATG-16.2, which promote membrane association of lipidated Atg8/LC3 proteins, redundantly promote polar body membrane breakdown in phagolysosomes independent of their role …

Does Muscle Pain Induce Alterations In The Pelvic Floor Motor Unit Activity Properties In Interstitial Cystitis/Bladder Pain Syndrome? A High-Density Semg-Based Study, Monica Albaladejo-Belmonte, Michael Houston, Nicholas Dias, Theresa Spitznagle, Henry Lai, Yingchun Zhang, Javier Garcia-Casado

2020-Current year OA Pubs

Several studies have shown interstitial cystitis/bladder pain syndrome (IC/BPS), a chronic condition that poses challenges in both diagnosis and treatment, is associated with painful pelvic floor muscles (PFM) and altered neural drive to these muscles. However, its pathophysiology could also involve other alterations in the electrical activity of PFM motor units (MUs). Studying these alterations could provide novel insights into IC/BPS and help its clinical management. This study aimed to characterize PFM activity at the MU level in women with IC/BPS and pelvic floor myalgia using high-density surface electromyography (HD-sEMG). Signals were recorded from 15 patients and 15 healthy controls …
