Effect On 360 Degree Video Streaming With Caching And Without Caching, Md Milon Uddin Dec 2022

Effect On 360 Degree Video Streaming With Caching And Without Caching, Md Milon Uddin

Electrical Engineering Theses

People all around the world are becoming more and more accustomed to watching 360-degree videos, which offer a way to experience virtual reality. While watching videos, it enables users to view video scenes from any perspective. To reduce bandwidth costs and provide the video with less latency, 360-degree video caching at the edge server may be a smart option. A hypothetical 360-degree video streaming system can partition popular video materials into tiles that are cached at the edge server. This study uses the Least Recently Used (LRU) and Least Frequently Used (LFU) algorithms to accomplish video caching and suggest a …


Wearable Sensors For Plants, Nafize Ishtiaque Hossain Dec 2022

Wearable Sensors For Plants, Nafize Ishtiaque Hossain

Electrical Engineering Theses

This thesis reports PlantFit: a research and development project that is intended to develop wearable sensors for plants. Plants are responsible for providing food, fiber, fuel, and fodder to the society. To overcome the problem of a limited land base, a more efficient farming approach needs to be developed, and thus precision farming is required. Precision farming would entail personalized healthcare in plants. When the plant is under any stress, the productivity declines. Plants release phytohormones, also known as early responders, in response to these stressors. The key crop phytohormones that respond to environmental stresses include salicylic acid (SA), indole-3-acetic …


An Integrated Electronic-Skin Patch For Real-Time And Continuous Monitoring Of A Panel Of Biomarkers Combined With Drug Delivery, Tanzila Noushin Dec 2022

An Integrated Electronic-Skin Patch For Real-Time And Continuous Monitoring Of A Panel Of Biomarkers Combined With Drug Delivery, Tanzila Noushin

Electrical Engineering Theses

Inflammatory biomarkers present in the human body play a vital role in medical field by guiding the clinician in decision-making for many diseases. The levels of these inflammatory biomarkers are associated with the severity and progress of several diseases. Researchers have found that increasing severity of many diseases such as cardiovascular disease, after surgery infection, and adverse clinical outcomes due to infectious diseases, results in the elevation of the level of inflammatory biomarkers in human sweat. Furthermore, the inflammatory cytokines indicate the pathophysiology and prognosis of critically ill SARS‑CoV‑2 patients. In this thesis work, different sensors have been developed for …


Surface Flashover Under Various Surface Conditions, Bradley A. Hannum May 2022

Surface Flashover Under Various Surface Conditions, Bradley A. Hannum

Electrical Engineering Theses

Electrical insulators are critical components used in every high voltage application whether it is operated continuously or in a pulsed mode. Bulk dielectric breakdown and surface flashover must be prevented in all use cases, especially those that occur in polluted environments. Though electrical standards have been written as a guide to prevent insulator surface flashover, such as Underwriters Laboratories (UL) 840, they are not directly applicable to applications where size and weight are critical. UL 840 experimental design is vague, does not consider all environments, and is written primarily with the electric power utilities in mind. The research presented here …


Development Of A Novel Sensor For Soil Moisture's Profile, Toan Canh Nguyen May 2022

Development Of A Novel Sensor For Soil Moisture's Profile, Toan Canh Nguyen

Electrical Engineering Theses

Monitoring of soil’s water content has been an important part of the irrigation system in farming, regional resources development, rainfall detection as well as disaster prevention. There has been studies and developments in this area over the decades. However, most of the works are focused on sensing the soil as a homogeneous medium, which does not accurately reflect the heterogeneous structure of soil. Works on multi-layer soil sensing have been researched and developed. Though, the current design is complex, not easy to produce and assemble. This work presents a novel low-cost and simple soil sensor design to detect the soil’s …
