A conceptual framework for the assessment of integrated energy storage resources
No full textConcerns regarding climate change impacts, energy security and sustainability are key drivers of the growing deployment of renewable energy resources. The variability, uncertainty and intermittency associated with the integration of these resources make the operation of the conventional power grid particularly challenging. Energy storage resources (ESRs) are one of the most promising solutions to address these challenges. The unique and versatile nature of storage finds its use in applications over a broad time spectrum. Furthermore, fast acting storage helps smoothen out the variable renewable output, minimize spillage of clean energy and manage the steep ramps associated with renewable energy integration. Storage also finds its use across all three domains of the electrical network, i.e., generation, transmission and distribution.
Cost reductions, technological innovations and regulatory initiatives have invigorated the interest in storage. However, the rapid growth of the storage sector is met by daunting challenges to the implementation of storage in the grid, especially since storage is very different from the conventional grid assets. The nature of storage is unique and its implementation has to be treated as such to fully harness the value it brings to the system it is integrated into. To this end, we outline a framework in this thesis for the integration of energy storage resources into the grid. The framework provides a systematic construct to study the various aspects of ESR integration in a system. The framework is comprehensive as it reflects the physical, information, environmental and financial aspects of storage operations. The thrust of the framework is its flexibility to accommodate the wide range of applications that storage provides on different time-scales. Furthermore, the framework explicitly captures the nature of deployment of storage for a particular application and shows the necessary interactions between ESR and the various players that interact with the ESR.
Case studies to illustrate the implementation of the information, environmental and financial layers of the framework are also presented in the thesis. The studies and their results establish that the framework is an extremely useful construct for the development of tools and models to aid in planning and operational studies and the formulation of policy and incentives and as such, is helpful in bringing the vision of energy storage closer to reality.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2018-05-01The student, Archana Manjunath, accepted the attached license on 2016-04-09 at 13:31.The student, Archana Manjunath, submitted this Thesis for approval on 2016-04-09 at 13:43.This Thesis was approved for publication on 2016-04-13 at 11:07.DSpace SAF Submission Ingestion Package generated from Vireo submission #9172 on 2016-07-07 at 13:49:01Made available in DSpace on 2016-07-07T20:27:12Z (GMT).

Insertion and deletion tolerance of point processes
No full textWe develop a theory of insertion and deletion tolerance for point processes. A process is insertion-tolerant if adding a suitably chosen random point results in a point process that is absolutely continuous in law with respect to the original process. This condition and the related notion of deletion-tolerance are extensions of the so-called finite energy condition for discrete random processes. We prove several equivalent formulations of each condition, including versions involving Palm processes. Certain other seemingly natural variants of the conditions turn out not to be equivalent. We illustrate the concepts in the context of a number of examples, including Gaussian zero processes and randomly perturbed lattices, and we provide applications to continuum percolation and stable matching
Emerg Infect Dis
No full textTo explain the spread of the 2014 Ebola epidemic in West Africa, and thus help with response planning, we analyzed publicly available data. We found that the risk for infection in an area can be predicted by case counts, population data, and distances between affected and nonaffected areas
Relatório de Estágio Logistic Operators: operational planning performance & decision targgets
No full textThis report presents a global perspective on the internship carried out in Luís Simões, S.A group and it also registers the planned and the enrolled activities.
The impact reached by logistics, in this “New Era” of worldwide dimensions, technologies and novel markets, introduced a progressive motivation to this area. Researchers and practitioners have recognised these opportunities and the new related social paradigms, presenting them in different scientific and technical papers. A special focus is devoted to the contributions emphasising the impact of planning and scheduling of logistic operators. These contributions were important incentives to the challenge provided by Luís Simões, S.A.
The core activities developed during the internship concerned the regular operation of a logistic operator namely, fleet planning and scheduling, warehouse control, monitoring and programming of clients and orders. Besides that, the development of some Key Performance Indicators (KPI) was also part of the objectives. Moreover, these desirably would be integrated within the new information system, Transportation Management System (TMS), implemented in Luís Simões, S.A. Herein, some improvement can be achieved concerning parameterisations, measurements and monitoring being reportable. These can be considered as TMS customisation for the practices of the group in Coimbra region
Clin Infect Dis
No full textBackground.West Nile virus (WNV) is the leading cause of arboviral disease in the United States and is associated with significant morbidity and mortality. A previous analysis found that a vaccination program targeting persons aged 6560 years was more cost-effective than universal vaccination, but costs remained high.Methods.We used a mathematical Markov model to evaluate cost-effectiveness of an age- and incidence-based WNV vaccination program. We grouped states and large counties ( 65100 000 persons aged 6560 years) by median annual WNV incidence rates from 2004 to 2017 for persons aged 6560 years. We defined WNV incidence thresholds, in increments of 0.5 cases per 100 000 persons 6560 years. We calculated potential cost per WNV vaccine-prevented case and per quality adjusted life-years (QALYs) saved.Results.Vaccinating persons aged 6560 years in states with an annual incidence of WNV neuroinvasive disease of 650.5 per 100 000 resulted in approximately half the cost per health outcome averted compared to vaccinating persons aged 6560 years in the contiguous United States. This approach could potentially prevent 37% of all neuroinvasive disease cases and 63% of WNV-related deaths nationally. Employing such a threshold at a county level further improved cost-effectiveness ratios while preventing 19% and 30% of WNV-related neuroinvasive disease cases and deaths, respectively.Conclusions.An age- and incidence-based WNV vaccination program could be a more cost-effective strategy than an age-based program while still having a substantial impact on lowering WNV-related morbidity and mortality.CC999999/ImCDC/Intramural CDC HHSUnited States/2022-11-02T00:00:00Z34117746PMC90705631205
Evidence of HIV-1 adaptation to HLA-restricted immune responses at a population level
No full textSelection of HIV-1 variants resistant to antiretroviral therapy is well documented. However, the selection in vivo of HIV-1 mutant species that can escape host immune system HLA class I restricted cytotoxic T-lymphocyte responses has, to date, only been documented in a few individuals and its clinical importance is not well understood. This thesis analyses the observed diversity of the HIV-1 reverse transcriptase protein in a well characterised, stable, HLA-diverse cohort of HIV-1 infected patients with over two thousand patient-years of observation. The results show that HIV-1 polymorphism is selected within functional constraints and is associated with specific HLA class I alleles. Furthermore, these associations significantly cluster along the sequence and tend to occur within known corresponding HLA-restricted epitopes. Absence of polymorphism is also HLA-specific and more often seen with common HLA alleles. Knowledge of HLA specific viral polymorphisms can be used to model an individual’s viral load from their HLA type and viral sequence. These results suggest that cytotoxic T-lymphocyte escape mutation in HIV-1 is critical to the host at an individual and population level as well as to short and long term viral evolution. This work provides new insights into viral-host interactions and has clinical implications for individualisation of HIV-1 therapy and vaccine design
