Development, Validation, And Testing Of A Novel Ergonomic Backpack, Lyndsey Kate Bouve

Theses and Dissertations (ETD)

Backpacks (BP) are one of the most common means for carrying loads but the loading mechanics that result from carrying heavy loads can have implications across the body. It has been suggested that loads in a BP should not excess 10-15% of the user’s body weight (BW) but that is not always feasible. The loads in a BP are transferred to the body via the shoulder strap which induce a shear and compressive force which act externally on the spine and transfer loads through it to the lumbar. Additionally, the weight of the bag induces an external moment that further …

Why Sigmoid Transformation Helps Incorporate Logic Into Deep Learning: A Theoretical Explanation, Chitta Baral, Vladik Kreinovich

Departmental Technical Reports (CS)

Traditional neural networks start from the data, they cannot easily handle prior knowledge -- this is one of the reasons why they often take very long to train. It is desirable to incorporate prior knowledge into deep learning. For the case when this knowledge consists of propositional statements, a successful way to incorporate this knowledge was proposed in a recent paper by van Krieken et al. That paper uses the fact that a neural network does not directly return a truth value, it returns a real value -- in effect, the degree of confidence in the corresponding statement -- from …

Cnn Feature Map Interpretation And Key-Point Detection Using Statistics Of Activation Layers, Allen Rush

Engineering Ph.D. Theses

Convolutional Neural Networks (CNNs) have evolved to be very accurate for the classification of image objects from a single image or frames in video. A major function in a CNN model is the extraction and encoding of features from training or ground truth images, and simple CNN models are trained to identify a dominant object in an image from the feature encodings. More complex models such as RCNN and others can identify and locate multiple objects in an image. Feature Maps from trained CNNs contain useful information beyond the encoding for classification or detection. By examining the maximum activation values …

Faculty Research 2023

Despite recent advances in the treatment of acute myeloid leukemia (AML), there has been limited success in targeting surface antigens in AML, in part due to shared expression across malignant and normal cells. Here, high-density immunophenotyping of AML coupled with proteogenomics identified unique expression of a variety of antigens, including the RNA helicase U5 snRNP200, on the surface of AML cells but not on normal hematopoietic precursors and skewed Fc receptor distribution in the AML immune microenvironment. Cell membrane localization of U5 snRNP200 was linked to surface expression of the Fcγ receptor IIIA (FcγIIIA, also known as CD32A) and correlated …

Housing As Asset And Payment: Construction, Speculation, And Financialization At The European Periphery, Smoki Musaraj

Sociology & Anthropology Open Access Publications

Construction booms have dominated Albania's economy and politics since the late 1990s. These booms continued even during times of illiquidity. One of the sources of financing construction in Albania is the practice of klering (in-kind payments). In this practice, developers pay subcontractors in (future) apartments in exchange for materials and labor. I argue that, in klering transactions, housing serves as an asset and a means of payment. The practice of klering emerged at the interface of postcommunist transformations, neoliberal reforms, and the fetishization of housing as an asset of more durable and multifaceted economic and cultural value. While grounded in …

UK CARES Faculty Publications

2,2’-Bis(4-dimethylaminophenyl)- and 2,2'-dicyclohexyl-1,1',3,3'-tetramethyl-2,2',3,3'-tetrahydro-2,2'-bibenzo[d]imidazole ((N-DMBI)2 and (Cyc-DMBI)2) are quite strong reductants with effective potentials of ca. −2 V vs ferrocenium/ferrocene, yet are relatively stable to air due to the coupling of redox and bond-breaking processes. Here, we examine their use in accomplishing electron transfer-induced bond-cleavage reactions, specifically dehalogenations. The dimers reduce halides that have reduction potentials less cathodic than ca. −2 V vs ferrocenium/ferrocene, especially under UV photoexcitation (using a 365 nm LED). In the case of benzyl halides, the products are bibenzyl derivatives, whereas aryl halides are reduced to the corresponding arenes. The potentials of the halides that can be …
