Solution Concerning Climate Change And Utilization Of Wind Turbine And Floating Pv In Coastal Area, Rifka Sofianita, Adi Surjosatyo, Sri Rachmawati Siregar

ASEAN Journal of Community Engagement

The global average sea level is rising at a rate of 3.2 mm per year according to recent observations of the IPCC. One of the main factors in sea level rise is thermal expansion, where greenhouse gases, especially CO2, accumulate and generate heat (climate change), thereby melting glaciers in the polar regions. Two villages in Kampung Bungin Bekasi, Indonesia, have already been experiencing flooding. Climate change can be addressed by environmental conservation and utilization of renewable energy to reduce CO2 production. Environmental conservation can be conducted by planting mangroves, while renewable energy is achieved by using natural renewable resources. Planting …

Magnetic Field Effects On Lithium Ion Batteries, Kevin Mahon

Theses

The Nobel Prize in Chemistry 2019 was just recently awarded to John B. Goodenough, M. Stanley Whittingham, and Akira Yoshino for the development of lithium-ion batteries. Lithium-ion batteries have seen use in many different industries and applications such as in portable devices, power grids, and electric vehicles. As lithium-ion batteries become more commonplace they will need to be modeled more extensively. The magnetic field effect on lithium-ion batteries has not been studied significantly since they were first discovered.

Modeling these batteries is still difficult because of the many complexities of the operation of a battery. Lithium-ion batteries are commonly modeled …

Study And Modelling Of Lithium Ion Cell With Accurate Soc Measurement Algorithm Using Kalman Filter For Electric Vehicles, Kasthuriramanan Mahendravadi Sivaguru

Theses

Lithium Ion cells are preferred over lead acid cells for electric vehicles due to their energy density, higher discharge current and size. The cost of lithium ion cells is scaling down compared to ten years earlier, but as their performance characteristics increase, the need for safety and accurate modelling also increases.

The absence of a generic cell model is associated to the different makes of cells and different chemistries of Lithium ion cells behave differently under the testing conditions required for every unique application. The focus of this thesis will be on how to provide intelligence to the battery management …

Impact Of Stirrer Speed And Media Type-Loading On The Breakage Kinetics During Wet Stirred Media Milling Of Griseofulvin, Nathaniel Parker

Theses

The aim of this study is to investigate the impact of stirrer speed (2000-4000 rpm) and bead loading (~20-60%) on the breakage kinetics-energy consumption during milling of griseofulvin, a poorly soluble drug, and compare the performance of crosslinked polystyrene (CPS) beads with that of yttrium-stabilized zirconia (YSZ) beads. Laser diffraction, SEM, viscometry, and XRPD were used for characterization. A microhydrodynamic model was used to interpret the breakage kinetics. An increase in stirrer speed led to faster breakage due to more frequent and forceful CPS bead-bead collisions. Despite causing slight decrease in maximum contact pressure, an increase in CPS bead loading …

Domain-Wall Tunneling Electroresistance Effect, M. Li, L. L. Tao, Evgeny Y. Tsymbal

Department of Physics and Astronomy: Faculty Publications

Ferroelectric tunnel junctions (FTJs) utilizing an in-plane head-to-head ferroelectric domain wall (DW) have recently been realized, showing interesting physics and new functionalities. However, the DW state in these junctions was found to be metastable and not reversible after applying an electric field. In this work, we demonstrate that a stable and reversible head-to-head DW state can be achieved in FTJs by proper engineering of polar interfaces. Using density functional theory (DFT) calculations and phenomenological modeling, we explore the DW stability by varying stoichiometry of the La_1−xSr_xO=TiO₂ interfaces in FTJs with La_0.5Sr_{0.5 …}

Antecedents Of Workplace Deviance: Role Of Job Insecurity, Work Stress, And Ethical Work Climate, Shuaib Ahmed Soomro, Yasir Mansoor Kundi, Muhammad Kamran

European Management Studies

This study examines why and how job insecurity affects employees’ deviant behaviour at work. To develop our hypotheses, we build on the conservation of resources theory. Our hypotheses suggested that job insecurity would be positively related to work stress and workplace deviance. Moreover, an ethical work climate was hypothesised to moderate the relationship between work stress and workplace deviance. Using data from 174 employees working in Multi-National Corporations (MNCs) located in Pakistan, the findings indicated that job insecurity has consequences for work stress and two facets of workplace deviance. Further, we found that an ethical work climate prevents employees from …
