Analysis of the Liberian Ebola Survivors Support System (ESSS)

Hanson, Jessi, Faley, Patrick Seeco, Quinn, Megan 01 January 2017 (has links) (PDF)
A systems theoretical analysis to capture the evolution and transition of the network systems supporting Ebola survivors and their affected communities, during the 2014-15 Ebola outbreak and recovery phases. The qualitative analysis includes a literature review, archival review, and interviews with representatives of key actors operating in strategic action fields. This paper uses a series of Diagrams that visually illustrate the various complex phases and their network changes that occurred and were established during the outbreak. This case analysis provides crucial phase information that both captures the historical events that informed the systems changes, including the development of the Ebola Survivors’ Support System (ESSS). Secondly, this analysis acts as, a model of understanding how disease support networks first emerge and can be better supported in other outbreaks.

Thermal Management Implications Of Utility Scale Battery Energy Storage Systems

Mohammad Aquib Zafar (16889376) 08 May 2024 (has links)
<p dir="ltr">The need for reducing reliance on fossil fuels to meet ever-increasing energy demands and minimizing global climate change due to greenhouse gas emissions has led to an increase in investments in Variable Energy Resources (VREs), such as wind and solar. But due to the unreliable nature of VREs, an energy storage system must be coupled with it which drives up the investment cost.</p><p dir="ltr">Lithium-ion batteries are compact, modular, and have high cyclic efficiency, making them an ideal choice for energy storage systems. However, they are susceptible to capacity loss over the years, limiting the total life of the batteries to 15-18 years only, after which they must be safely discarded or recycled. Hence, designing a Battery Energy Storage System (BESS) should consider all aspects, such as battery life, investment cost, energy efficiency, etc.</p><p dir="ltr">Most of the available studies on cost and lifetime of BESS either consider a steady degradation rate over years, or do not account for it at all, they take constant charge/discharge cycles, and sometimes do not consider ambient temperature too. This may result in an error in estimation of the cost of energy storage. The location where the BESS is supposed to be installed can also impact its life, given that each location has its own power consumption trend and temperature profile. In this work, we attempt to simulate a BESS by considering the ambient temperature, degradation rate and energy usage. This will help in getting an insight of a more realistic estimate of levelized cost of storage and for estimating the thermal energy needed to keep them within a certain temperature range, so that they can last longer.</p>
