Impact of Coupling an Ocean Model to WRF Nor’easter Simulations
No full textThe impact of ocean–atmosphere coupling and its possible seasonal dependence upon Weather Research and Forecasting (WRF) Model simulations of seven, wintertime cyclone events was investigated. Model simulations were identical aside from the degree of ocean model coupling (static SSTs, 1D mixed layer model, full-physics 3D ocean model). Both 1D and 3D ocean model coupling simulations show that SSTs following the passage of a nor’easter did tend to cool more strongly during the early season (October–December) and were more likely to warm late in the season (February–April). Model simulations produce SST differences of up to 1.14 K, but this change did not lead to significant changes in storm track ( 1) and have low-to-moderate threat scores (0.31–0.59). Analysis of the storm environment and the overall simulation failed to reveal any statistically significant differences in model error attributable to ocean–atmosphere coupling. Despite this result, ocean model coupling can reduce dynamical field error at a single level by up to 20%, and this was slightly greater (1%–2%) with 3D ocean model coupling as compared to 1D ocean model coupling. Thus, while 3D ocean model coupling tended to generally produce more realistic simulations, its impact would likely be more profound for longer-term simulations.© Copyright 2015 American Meteorological Society (AMS).

Re-imagining decker Lake Park
No full textreportDecker Lake Park is a Class Two Regional Park located in West Valley City. For years, the park has had unmet maintenance and supervision needs and, as a result, the park\u27s function and purpose to serve all users has been limited. The problems facing Decker Lake Park range from non-ADA complying infrastructure to poor environmental quality, which, if not addressed, will lead to issues for businesses and residents living nearby. Therefore, efforts have been made to monitor and record existing conditions of Decker Lake Park. The observations show that the park needs funding for maintenance and supervision to improve infrastructure, amenities, and environmental conditions. There are also current proposals to provide funding to add new amenities to the park, but they do not address the park\u27s existing conditions. Therefore, future recommendations proposed for the park should include strategies and methods to improve park accessibility, promote park inclusivity, and increase park funding. A public-private partnership consisting of West Valley City, Salt Lake County, and Keep Decker Lake Beautiful is highly recommended to implement future recommendations outlined in this report and to build support for the park from nearby residents and organizations. In general, the park\u27s future will be determined by how the conditions at the park improve based on this report\u27s recommendations and additional recommendations derived from future public input and community engagement

A Cross-Layer Multicast-Push Unicast-Pull (MPUP) Architecture for Reliable File-Stream Distribution
No full textThe growing deployment of OpenFlow/SDN networks makes it increasingly possible to leverage network multi-cast services. This work proposes a novel cross-layer Multicast- Push Unicast Pull (MPUP) architecture that includes functionality in the application, transport and link layers to offer users a reliable file-stream distribution service to multiple subscribers. A prototype implementation of the MPUP architecture was realized in a new version of Local Data Manager (LDM), LDM7, a software program that has been in use since 1994 for real-time meteorology data distribution. LDM6, the currently deployed version, uses application-layer multicast. Experiment were run on the GENI infrastructure to compare LDM7 and LDM6. The two main findings are (i) LDM7 can be run at a higher sending rate than LDM6 allowing for improved performance (lower file-delivery latency), and (ii) to achieve the same performance, LDM7 uses significantly lower bandwidth and compute capacity. A three-fold improvement in performance improvement was possible with LDM7, and a bandwidth reduction from 350 Mbps to 21.4 Mbps was observed with 24 receivers.Peer reviewe
What happened to the tripple-decker?
No full textThesis (S.M. and M.C.P.)--Massachusetts Institute of Technology, Dept. of Urban Studies and Planning, 2006.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Includes bibliographical references (p. 112-115).This thesis examines the three-decker, a type of small apartment house ("superposed flats") that is common in the Boston metropolitan region and elsewhere in New England. The three-decker is distinctive in two ways: its physical form, which is moderately dense and yet modest in scale; and its tenancy structure, which typically involves one household owning the entire building, while residing in one apartment and renting out the other two. This thesis poses three, interrelated questions: What is the origin of the three-decker? Why did it substantially disappear in the Boston area after 1920, and altogether by 1930? And what has kept it from coming back? In order to get at these questions, the thesis both examines the three-decker in its local context, and compares and contrasts it with similar building types in three other North American cities that have a rich tradition in them: Chicago, Montreal, and New York City. Chapter 1 introduces the topic and describes the three-decker and its counterparts elsewhere. Chapter 2 is a historical analysis that addresses the questions of the origins and decline of the three-decker.(cont.) Chapters 3, 4, 5 examine in turn design, economic, and regulatory factors that impinge, either negatively or positively, on the prospects for the three-decker and similar building types in the present day. Chapter 6 offers a summary of the findings, along with policy recommendations pertaining to the encouragement of superposed flat production and some final thoughts on the viability of the three-decker today. The three-decker is found to be a building type that is problematic in all but a few limited applications in the current era. However, the broader category of superposed flats is found to offer a great deal of potential, both for urban form-giving and for affordable housing. This potential is currently being realized, to different extents and in different ways, in Chicago, Montreal and New York, but not in Boston. This thesis argues that this should change, and that furthermore the superposed flats family of buildings has a lot to offer to cities - the majority of metropolitan areas on the North American continent - where it has never been part of the palette of residential forms.by Jacob Wegmann.S.M.and M.C.P

Effects of burn season on bee and floral community in tallgrass prairies, and the use of museum collections data
No full textPrescribed fires (controlled burns) in tallgrass prairie systems are a common land management technique used across the United States to maintain species diversity. Burns are conducted either in the winter or early spring (dormant season) or in late summer and early fall (growing season). Prairies are rich in diverse bee taxa, including many solitary and social species. It is unknown if dormant season or growing season burns differentially affects the following year’s bee community and their resources. Chapter 1 addresses the question of how fires affect bees in prairie fragments in Illinois. Understanding the effects of the different burn seasons will aid future pollinator- and bee-friendly land management and restoration projects. In 2016 and 2017, bees were collected from seven prairie sites in south-central Illinois using active netting, pan traps, and vane traps. Overall, both burn seasons increased the amount of bare ground compared to unburned areas, but growing season burns contained greater total area of bare ground than dormant season burns. This resulted in an increase in abundance of below-ground nesting bee species after growing season burns. The decrease in nesting material for above-ground nesting bees in the burned treatments resulted in a lower proportional abundance of those species compared to areas that were not burned. However, comparing the dormant and growing seasons of burn, there was no effect on the overall bee community. Amount of semi-natural area in the landscape and the matrix surrounding each prairie fragment may play a larger role in maintaining stable bee communities in highly fragmented habitats. Land managers can burn during both seasons knowing that bee communities will not be adversely affected.
Chapter 2 utilizes the museum specimens housed at the Illinois Natural History Survey (INHS), University of Illinois, to address several issues concerning the use of museum collections to detect species distribution shifts and declines. Many changes to species distributions often occur over long time scales, where museum records are the only source of information regarding the historical occurrences of species. Efforts to digitize museum collections aids in identifying areas and species for conservation, but sampling biases and differences in specimen deposition into museum collections by various collectors over time, data entry errors, and misidentification of specimens can limit the accuracy of date collected from museums. This chapter describes the activities of compiling an updated Illinois bee species checklist of 455 species, correcting errors found in the INHS online database, and identifying potential new county and one state records (Diadasia enavata Cresson, 1872) for Illinois from the collections conducted in Chapter 1. Continued support for natural history museums across the country will allow future research on the impacts to ecosystems caused by human and natural influences.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-12-01The student, Brenna Decker, accepted the attached license on 2017-12-07 at 12:58.The student, Brenna Decker, submitted this Thesis for approval on 2017-12-07 at 13:05.This Thesis was approved for publication on 2017-12-08 at 12:02.DSpace SAF Submission Ingestion Package generated from Vireo submission #11904 on 2018-03-13 at 09:57:38Made available in DSpace on 2018-03-13T15:28:40Z (GMT).

Templated tetramerization of dicyanobenzenes to form mixed porphyrinato and phthalocyaninato rare earth (III) triple-decker complexes
No full textHeteroleptic porphyrinato/phthalocyaninato rare earth(III) triple-decker compounds M-2(Por)(2)(Pc') (1a-4a) and M-2(Por)(Pc')(2) (1c-4c) (M = Eu, Tb; Por = TDOPP, Pc' = OOPc or Por = TpClPP, Pc' = Pc where H-2(TDOPP) = 5,10,15,20-tetrakis(4-n-dodecyloxyphenyl)porphyrin, H-2[OOPc] = 2,3,9,10,16,17,23,24-octakis(n-octyloxy)phthalocyanine, H-2(TpClPP) = 5,10,15,20-tetrakis(4-chlorophenyl)porphyrin, H-2(Pc') = general phthalocyanine, and H-2(PC) = unsubstituted phthalocyanine) were obtained by the cyclic tetramerization of the corresponding dicyanobenzenes 7 using monoporphyrinato rare earth(III) acetylacetonates M(Por)acac as templates with catalysis by the organic base 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). Double-decker complexes M(Por)(Pc') (M = Eu, Tb; Por = TDOPP, Pc' = OOPc or Por = TpClPP, Pc' = Pc) (1b-4b) were isolated as side products. For the purpose of comparative study, homo- and hetero-dinuclear rare earth triple-deckers with one porphyrinato and two phthalocyaninato ligands M-2(Por)(Pc')(2) (1c, 2c) (M = Eu, Tb; Por = TDOPP, Pc' = OOPc) and (Por)M(Pc')M'(Pc') (M not equal M' = Eu, Tb) (5c, 6c) were also prepared using the raise-by-one-story method. The complexes were characterized by UV-vis, near-IR, IR and mass spectra. The comparison between H-1 NMR spectra of the two series of triple-decker compounds a and c, and also between the substituted phthalocyanine- and unsubstituted phthalocyanine-containing europium triple-deckers, renders it possible to assign the aromatic proton signals unambiguously.
