Management Concepts In Shishupalavadha, Sathyanarayanan V

Theses and Dissertations

Management of organizations, people, and entities has been a subject matter of great interest today. Schools of business and management were established in the West about 125 years ago, and countries in other parts of the world, including India, simply followed these practices. Consequently, there is a widespread feeling today that management concepts originated in the West. All Indian business schools teach management concepts propounded by Western scholars in the last 100 years or so.

Going by the first principles, whenever multiple people, resources, entities, and institutions are involved, there is a requirement for Management. This implies that management as …

Exploring The Intersection Of Race And Native Speakerism In English Language Teaching: Experiences Of Black African Teachers In Turkey, John Ayodeji Odudele

Linguistics

Research on race and native speaker status in language teaching provides little insight into the experiences of Black African English teachers (BAETs) in the diaspora. To address this gap, this study examines how aspects of BAETs' positionalities - such as race and native speaker status create challenges in their professional and societal lives in Turkey. Data from twelve semi­ structured interviews of BAETs were analyzed using thematic analysis. Findings suggest that race­ related challenges trump language-related ones and that Blackness fundamentally shapes outsiders’ perception and value of BAETs’ linguistic expertise. Even when BAETs possess the same or superior qualifications as …

Development Of Low-Profile Wideband Microstrip Antennas For Cubesat Phased-Array Applications, Mitchell R. Hay

Engineering

CubeSat missions rely heavily on effective communication systems in order to transmit and receive large amounts of data quickly and efficiently. The total throughput is limited by the capacity of the channel - a quantity dependent upon the signal quality and bandwidth of the link. Volume and power constraints on a CubeSat impede overall capacity in a fixed bandwidth channel. Phased-array antennas provide a more power efficient solution to improving signal quality by optimizing the spatial properties of the link, rather than broadcasting higher signal power over a broader area through power amplification alone. In order to take advantage of …

Effects Of Eogo In Metakaolin-Based Geopolymer, Chaewon Lee, Hoyoung Lee, Jinwoo An, Boo Hyun Nam

Civil Engineering Faculty Publications

Geopolymer concrete uses a geopolymer binder instead of traditional Portland cement; thus, it reduces carbon emissions by a significant amount. In this study, Edge-Oxidized Graphene Oxide (EOGO), a carbon-based nanomaterial, was added into a metakaolin-based geopolymer, and its effect on the mechanical and rheological properties of the mixture was investigated. EOGO was added into the mixture at 0% (control), 0.1%, 0.5%, and 1% of the metakaolin mass. Several experiments were conducted to characterize the properties of the metakaolin–EOGO (MKGO) geopolymer, including its compressive strength, free–free resonance column (FFRC), void content, water absorption, setting time, flow, and rheology.

Exploring Longitudinal Stability Of Spatiotemporal Sequential Patterns By Means Of Autoencoder Schemes For Eeg Based Personal Identification, Muhammed E. Oztemel

LSU Doctoral Dissertations

Robust personal identification remains a critical and challenging task in the digital era. Electroencephalography (EEG) offers a unique biometric modality that captures individual brain dynamics through complex neural signals. This dissertation proposes autoencoder (AE) based feature extraction and subject identification through these features. EEG recordings are first transformed into topographic maps to represent spatial brain activity. Consecutive topomaps are then concatenated to capture temporal transitions across frames. Convolutional autoencoders (CAEs) are used to learn spatial and temporal patterns, while domain-adaptive AEs are designed to model evoked potential based responses. Additionally, self-attention mechanism is incorporated to enhance feature representation. To analyze …

Geotechnical Investigation Of Sand Flow Slides, Haines, Alaska, Christopher Kalev

Engineering

The Lutak Spur (LS) - a prominent glacio-deltaic landform located near Haines, Alaska - formed during the retreat of the Cordilleran Ice Sheet during the Last Glacial Maximum. This study evaluates its geologic evolution, soil development, and hydrologic-slope stability response to a December 2020 atmospheric river (AR) event, which triggered multiple slope failures. Geologic mapping and interpretation of previous work suggest that the LS formed as an ice­ contact kame delta at the margin of a retreating valley glacier. Following deglaciation, post­ glacial isostatic adjustment and sea-level changes exposed the LS surface, allowing for the development of Spodosols with iron-cemented …
