Building a Digital Twin of the University of North Texas Using LiDAR and GIS Data

Bhattacharjee, Shwarnali 12 1900 (has links)
Digital twins are virtual renditions of the actual world that include real-world assets, connections, activities, and processes. Recent developments in technologies play a key role in advancing the digital twin concept in urban planning, designing, and monitoring. Moreover, the latest developments in remote sensing technology have resulted in accurate city-scale light detection and ranging (LiDAR) data, which can be used to represent urban objects (buildings, vegetation, roads, and utilities), enabling the creation of digital twin of urban landscapes. This study aims to build a digital twin of the University of North Texas (UNT) using LiDAR and GIS data. In this research, LiDAR point clouds are used to create 3D building and vegetation modeling along with other GIS data (bicycle racks and parking areas) in creating a digital twin model. 3D Basemap solutions of ArcGIS Pro and ArcGIS Online Scene Viewer, respectively, are used to create an initial 3D urban model and build the ultimate digital twin of UNT. The emergency management floorplans of UNT buildings are incorporated into the digital twin to increase emergency management efficiency. Moreover, solar power potential for individual buildings at UNT has been estimated using the Digital Surface Model (DSM) and integrated into the digital twin model to identify the buildings with the highest solar energy capacity. This study indicates that implementing a digital twin in a university enhances campus efficiency, safety, and sustainability, serving as a central system for a smart campus and contributing to intelligent urban growth.

Internet Impact On UNT Traditional Newspaper

Nnagbo, Emmanuel Onyebuchi January 2011 (has links)
The aim of this research is to understand the Internet impact on Uppsala Nya Tidning (UNT) traditional newspaper. By answering the question; has the internet resulted in UNT developingnew products? A case study was selected. The findings indicate that the internet has resulted in UNT consumers, demanding quick, free, and user-generated news. The fact that the newspaper is presently unable to accommodate these different needs have made the consumers discard the paper, thus causing a decrease in UNT newspaper readership. This, however, resulted in UNT developing  new  products (e.g., Free online reading, tabloid newspaper, and multimedia portfolio).

Multi-year Operation Effect of Geothermal Heat Exchanger on Soil Temperature for Unt Zero Energy Lab

Walikar, Vinayak P. 12 1900 (has links)
Ground source heat pump (GSHP) uses earth’s heat to heat or cool space. Absorbing heat from earth or rejecting heat to the earth, changes soil’s constant temperature over the multiple years. In this report we have studied about Soil temperature change over multiple years due to Ground loop heat exchanger (GLHE) for Zero Energy Research Laboratory (ZØE) which is located in Discovery Park, University of North Texas, Denton, TX. We did 2D thermal analysis GLHP at particular Depth. For simulation we have used ANSYS workbench for pre-processing and FLUENT ANYS as solver. TAC Vista is software that monitors and controls various systems in ZØE. It also monitors temperature of water inlet/outlet of GLHE. For Monitoring Ground temperatures at various depths we have thermocouples installed till 8ft from earth surface, these temperatures are measured using LabVIEW. From TAC Vista and LabVIEW Reading’s we have studied five parameters in this report using FLUENT ANSYS, they are; (1) Effect of Time on soil Temperature change over Multi-years, (2) Effect of Load on soil temperature change over Multi-years, (3) Effect of Depth on soil temperature change over Multi-years, (4) Effect of Doubling ΔT of inlet and outlet of GLHE on soil temperature change over multi-years and (5) Effect on soil temperature change for same ZØE Laboratory, if it’s in Miami, Florida. For studying effect of time on soil temperature change for multi-years, we have varied heating and cooling seasons. We have four cases they are Case A: GSHP always “ON” (1) 7 months cooling and 5 month cooling and (2) 257 days are cooling and 108 days heating. Case B: GSHP “OFF” for 2 months (1) 7 months cooling and 3 months heating and (2) 6 months cooling and 4 month heating. For Studying Effect of Load on soil temperature change over multi-years, we have considered maximum temperature difference between inlet and outlet for heating and cooling season for simulation. For studying effect of doubling ΔT of inlet and outlet of GLHE, we have doubled the temperature difference between inlet and outlet of GLHP. There will be soil temperature change over year at various depths. For studying Effect of Depth on soil temperature change for multi-years, we have consider 5 depths, they are 4ft, 6ft, 8ft, 110ft and 220ft. The Densities of soil are known from site survey report of ZØE GSHP manufacturers till depth of 13ft. For studying effect of soil temperature over multi-years for same ZØE in Miami, Florida, we have considered equivalent cooling and heating season from weather data for past one year and assuming same number of days of cooling and heating for next 20 years we have simulated for soil temperature change.

Tre relationer - ett förhållande : - en fallstudie av trepartsförhållandet mellan UNT, läsare och annonsörer

Axelsson, Julius, Krontoft, Pontus January 2010 (has links)
<p>Följande studie undersöker i vilken utsträckning parterna i trepartsförhållandet Upsala Nya Tidning, annonsör och läsare har överensstämmande åsikter om vad som är viktigt i relationen, samt hur väl de känner till varandras uppfattningar. Vi väljer att studera förhållandet ur ett trepartsperspektiv då de mer traditionella tvåpartsförhållandena inte är tillräckliga för att beskriva den komplexa verkligheten. Studien utgår från UNT:s printupplaga, men skildrar även skillnader mellan den och webbupplagan. Ett representativt urval av varje part tillfrågades via en enkätundersökning vad de själva tycker är viktigt och vad de uppfattar är viktigt för övriga parter. Resultatet visar på att parterna inte har överensstämmande åsikter om vad som är betydelsefullt i relationen. Hur väl parterna känner till varandras uppfattningar skiljer sig mellan de olika variablerna. Vidare konstateras att skillnaden både i åsikt och kännedom om varandras åsikter på webb- och printupplaga är mycket liten.</p>

“Almost Astronauts”: Short Stories

Miller, Laura I. 05 1900 (has links)
In this collection of short stories, I abduct experiences from my own life and take them on an imaginative journey. I experiment with elements of structure and point of view, often incorporating the magical or surreal to amplify the narrator’s internal landscape. As demonstrated in the title story, “Almost Astronauts,” these stories all deal with a sudden and sometimes destructive shift in the narrator’s perspective.

Object Detection for Aerial View Images: Dataset and Learning Rate

Qi, Yunlong 05 1900 (has links)
In recent years, deep learning based computer vision technology has developed rapidly. This is not only due to the improvement of computing power, but also due to the emergence of high-quality datasets. The combination of object detectors and drones has great potential in the field of rescue and disaster relief. We created an image dataset specifically for vision applications on drone platforms. The dataset contains 5000 images, and each image is carefully labeled according to the PASCAL VOC standard. This specific dataset will be very important for developing deep learning algorithms for drone applications. In object detection models, loss function plays a vital role. Considering the uneven distribution of large and small objects in the dataset, we propose adjustment coefficients based on the frequencies of objects of different sizes to adjust the loss function, and finally improve the accuracy of the model.

Correlational Study of the UNT Neuropsych-Screen, the MMPI and Time among Chronic Pain Patients

Smith, Russell Joseph 06 1900 (has links)
Although many theorists have speculated that chronic pain may be linked to some sort of central neuropsychological integration deficit, a review of the current literature reveals no empirical support for this theory. This study attempts to assess the severity, if any, of neuropsychological deficits in chronic pain subjects by using a neuropsychological screen developed at the University of North Texas. Also, presented are studies of correlations between the UNT Neuropsych-screen and the MMPI. the Dallas Pain Questionnaire (DPQ), the Dallas Pain Drawing CDPD), and time since injury in order to assess any possible relationships. The subjects in this study consist of 100 volunteers. Of these subjects, 74 were patients of the Spinal and Chronic Pain Center at Medical Arts Hospital in Dallas, Texas and represented the clinical population. The remaining 26 subjects were staff volunteers from the hospital . The results of the study indicate significant differences between chronic pain subjects and non-pain subjects across many areas of neuropsychological functioning, as well as other significant correlations among many of the variables. The implications of this study are elaborated upon, in the discussion section, in detail along with limitations and future research directions.
