Design and development of a novel DC/DC bidirectional converter with dual solar/PV-based snow removal and EV charging functionality
… system. One of these factors is the effect of snow cover on PV panels, a subject lacking sufficient academic research. This thesis reviews current research for snow removal in solar PV modules and power electronic circuit topologies used. Additionally, it presents the design, analysis and …

Walking in old age: A year-round perspective on accessibility in the outdoor environment and effects of measures taken
… to improve accessibility in both bare-ground and snow/ice conditions are implemented. An index, developed within this thesis, shows a large variation in the implementation process concerning accessibility among Swedish municipalities. Thus, there is still much to do to accomplish a society …

Calibration of Snowmaking Equipment for Efficient Use on Virginia's Smart Road
… bed for numerous research activities including snow and ice control, remote sensor testing, snow removal management, safety and human factors, and vehicle dynamics. An all-weather testing system will feature 75 automated snowmaking towers. In order to provide timely and repeatable weather …

Comparison of enclave and individual employment of individuals with mental disabilities within college grounds departments
… that are involved in litter control, leaf removal, weeding, and snow removal. This method of employment has provided permanent employment for ten IMD. VPI & SU’s success with enclave employment prompted the development of first a statewide, then a national survey to determine the …

Assessing Maintenance and Management of Infrastructure Systems Using Citizen Reported Service Requests
… to problems with their water, sanitation, snow removal, and traffic congestion. In the first manuscript, service requests were compared to socio-economics within zip codes. Zip codes were clustered by four socio-economic variables including median house value, percent of the population with …

THE EFFECT OF BIOTIC AND ABIOTIC FACTORS WITHIN THE SOIL ENVIRONMENT ON THE MORTALITY OF IXODES SCAPULARIS DURING THEIR OFF-HOST PERIODS
… To further explore the effect of winter weather, snow cover was manipulated over microcosms containing I. scapularis nymphs. At the end of the season snow removal was found to have no effect on overwinter tick survival, but there was a negative relationship between tick survival and the number of …

Carbon dynamics under natural and manipulated meteorological boundary conditions in a forest and a fen ecosystem
… is more likely to occur as rain rather than snow, resulting in reduced snowpacks in winter. In some regions, this can lead to an increasing frequency of soil frost. In summary, changes in the global water cycle can significantly affect boundary conditions within soils. This thesis …

Soil organic matter dynamics in a temperate forest influenced by extreme weather events
… middle of February 2006 we removed the natural snow cover during winter on three replicate plots. Hence we induced soil frost to 15 cm depth (in a depth of 5 cm below surface up to -5°C) from January to April 2006, while the snow-covered control plots never reached temperatures below 0 °C. In …

IMPACTS OF URBAN DEVELOPMENT PATTERN ON RUNOFF PEAK FLOWS AND STREAMFLOW FLASHINESS OF PERI-URBAN CATCHMENTS: ASSESSING THE PERFORMANCE OF PHYSICAL AND DATA-DRIVEN MODELS FOR REAL-TIME ENSEMBLE FLOOD FORECASTING
… is least in winter. Furthermore, winter snow redistribution by plowing and endogenous urban heat affect the snowmelt timing and frequency. Due to the limited availability of data on snow removal and redistribution activities in northern peri-urban catchments, cold-season hydrologic …
