Application Of Recurrent Neural Network For The Prediction Of Target Non-Apneic Arousal Regions In Physiological Signals, Naimahmed Nesaragi, Shubha Majumder, Ashish Sharma, Kouhyar Tavakolian, Shivnarayan Patidar

Electrical Engineering Faculty Publications

This work presents a new method for detection of target non-apneic arousals by applying a recurrent neural network architecture on the various specified polysomnographic (PSG) signals. The proposed two stage architecture uses sequences of instantaneous frequencies and spectral entropies of the chosen PSG signals as feature vectors. At the first stage, these feature vectors are used to train several long-short term memory (LSTM) models. The LSTM networks can learn long-term relationships between time steps of time-frequency based sequences obtained out of physiological signals. As a second stage, some quadratic discriminant (QD) layers are modelled and appended to the trained LSTMs …

Determining The Respiratory State From A Seismocardiographic Signal - A Machine Learning Approach, Christian Ulrich, Martin Jensen, Rolf Oberlin, Kouhyar Tavakolian, Farzad Khosrow-Khavar, Andrew Blaber, Kasper Sørensen, Samuel Schmidt

Electrical Engineering Faculty Publications

Seismocardiography (SCG) is a non-invasive method for measurement of vibrations on the chest wall originating from the heart. Respiration changes the morphology of the SCG-signal and analyzing these changes could improve the diagnostic value of SCG. This study aimed to determine the nasal respiration signal amplitude at mitral closure (MC) and aortic opening (AO) using SCG features. The three proposed methods for this were multiple regression analysis (MRA), support vector regression (SVR), and a neural network (NN). SCG, Electrocardiography and nasal-catheter flow signals were acquired from 18 healthy subjects (age 29± 6). SCG-signal fiducial points were used as features and …

An Initial Study Of The Catalytic Reforming Of Crop Oil‐Derived 1‐Alkenes With Hzsm‐5 To Aromatic Hydrocarbons, Shelby Amsley‐Benzie, Swapnil Fegade, Brian Tande, Alena Kubatova, Evguenii Kozliak, Wayne Seames

Chemical Engineering Faculty Publications

This study explored the production of aromatic hydrocarbons from the longer‐chain alkenes produced by the pyrolysis/cracking of crop oils. 1‐Tetradecene, serving as a model compound for these alkenes, was reformed in a batch reactor with a HZSM‐5 catalyst to produce a liquid hydrocarbon mixture with a high‐aromatic content. These reactions resulted in a >99% conversion of the 1‐tetradecene feedstock with a yield of up to 22 wt% of aromatic hydrocarbons. Surprisingly, isomers of C3‐substituted benzenes along with xylenes and diaromatics (lower homologs of alkyl‐substituted indanes and naphthalenes) were the main aromatic products rather than their lower‐molecular‐weight (MW) homologs, benzene, toluene, …

Overall Psd And Fractal Characteristics Of Tight Oil Reservoirs: A Case Study Of Lucaogou Formation In Junggar Basin, China, Xixin Wang, Jiagen Hou, Yuming Liu, Peiqiang Zhao, Ke Ma, Dongmei Wang, Xiaoxu Ren, Lin Yan

Geology and Geological Engineering Faculty Publications

Lucaogou tight oil reservoir, located in the Junggar Basin, Northwest of China, is one of the typical tight oil reservoirs. Complex lithology leads to a wide pore size distribution (PSD), ranging from several nanometers to hundreds of micrometers. To better understand PSD and fractal features of Lucaogou tight oil reservoir, the experiment methods including scanning electron microscope (SEM), rate-controlled mercury injection (RMI) and pressure-controlled mercury injection (PMI) were performed on the six samples with different lithology. The results indicate that four types of pores exist in Lucaogou tight oil reservoir, including dissolution pores, clay dominated pores, microfractures and inter-granular pores. …

Developing A New Storage Format And A Warp-Based Spmv Kernel For Configuration Interaction Sparse Matrices On The Gpu†, Mohammed Mahmoud, Mark Hoffmann, Hassan Reza

Computer Science Faculty Publications

Sparse matrix-vector multiplication (SpMV) can be used to solve diverse-scaled linear systems and eigenvalue problems that exist in numerous, and varying scientific applications. One of the scientific applications that SpMV is involved in is known as Configuration Interaction (CI). CI is a linear method for solving the nonrelativistic Schrödinger equation for quantum chemical multi-electron systems, and it can deal with the ground state as well as multiple excited states. In this paper, we have developed a hybrid approach in order to deal with CI sparse matrices. The proposed model includes a newly-developed hybrid format for storing CI sparse matrices on …

A Phonology Of Hill (Kone-Tu) Asho, Daniel Tignor

Theses and Dissertations

Asho (ISO 639-3: csh) is a Tibeto-Burman language in the Southern Chin branch of Kuki-Chin. It is spoken by about 170,000 people, primarily in western and west-central Myanmar (Simons & Fennig 2018). Although Asho received some early attention in the studies of Tibeto-Burman languages (Houghton 1892; Joorman 1906), it has remained mostly unstudied for the past century. Current data confirm the traditional distinction of two basic dialects of Asho (Hill and Plains), and this paper focuses on the Hill or "Kone-tu" dialect. The Hill dialect has 26 consonants (compared to 29 in the Plains dialect), and both dialects have 14 …
