OPTIMIZATION OF ENERGY AND WATER QUALITY COSTS FOR DRINKING WATER UTILITIES
(2021-08)INTRODUCTION A drinking water utility operates with the primary goal to provide safe, aesthetically pleasing water to its customers while meeting demand at a reduced cost. In doing so, the water utility considers the ... -
Optimization of Growth Conditions for the Model Bacterium Synechococcus sp. PCC 7002 for Chemical Production Using Wastewater-Based Media
(2017-06-07)The term “cyanobacterial biorefinery” refers to the application of genetically engineered cyanobacteria for production of chemicals that could serve as an alternative source to petroleum derivatives. Various life cycle ... -
OPTIMIZATION OF PUMPING RELATED ENERGY USE AND COST IN A MUNICIPAL DRINKING WATER SYSTEM
(2019)In terms of water production, Madison Water Utility (MWU) is the largest groundwater-sourced utility in the state of Wisconsin (Bohnert, 2012). In 2017 alone, MWU pumped 9.42 billion gallons of water while consuming 20.3 ... -
OVERVIEW OF THE DDAC-REACT SYSTEM: A COUPLED DIRECT AIR CAPTURE AND MINERALIZATION PROCESS
(2022-05-31)Abstract A study by the Rhodium group shows that in order for the US to reach net-zero by 2045, 560 to 1850 million metric tons of CO2 will need to be removed by DAC technologies depending on the growth of other carbon ... -
Performance of Integrated Project Delivery (IPD) For Mechanical and Electrical Contractors
(2013-08-25)Integrated Project Delivery (IPD) is a relatively new delivery system that is generating much interest in the construction industry today. IPD is characterized by a multiparty contract and the very early involvement of key ... -
A Pilot Scale Study of Low Dissolved Oxygen Nutrient Removal Supplemented with Ammonia-Based Aeration Controls
(2018-06-22)In order to refine a previously acclimated pilot to low dissolved oxygen (DO) conditions for nutrient removal, ammonia-based aeration control was introduced in an effort to successfully remove ammonia throughout an entire ... -
A Pilot Scale-Study at the Nine Springs Wastewater Treatment Plant: Seasonal Cod and F/M Ratio Trends and Their Application To Modeling Treatment Processes
(2021-05)Wastewater treatment is a complex process that involves the simultaneous application of diverse sciences such as chemistry, biology, and engineering. Chemistry allows to describe the composition of wastewater through the ... -
POWER SYSTEM MODELS FORMULATED AS EIGENVALUE PROBLEMS AND PROPERTIES OF THEIR SOLUTIONS
(2010-12-15)Eigenvalue problems incorporate multiplicative nonlinearities in otherwise linear equations. Two power systems models with multiplicative nonlinearities are reformulated as eigenvalue problems. Reformulation allows for ... -
PREDICTING PRODUCTION RATES IN THE WISCONSIN HIGHWAY CONSTRUCTION INDUSTRY USING COMPUTER TOOLS
(2016-10-14)Poor estimates of project contract completion time can produce dire consequences. Awarding too much time to complete a project creates conditions where contractors may be encouraged to perform work less aggressively, while ... -
Probabilistic Streamflow Forecasts to Advance Flood Preparedness: Statistical Applications and User Perspectives
(2021-05)Disaster planning has historically allocated minimal effort and finances toward advanced preparedness; however, evidence supports reduced vulnerability to flood events through appropriate early actions, saving lives and ... -
Qualitative Analysis of Lost Labor Productivity in Electrical Construction from the Perspective of Field Personnel
(2018-05-31)Executive Summary The stagnant production practices, the decline in experienced workers, and the steep economical labor cost has challenged the construction industry to improve labor production practices. This research ... -
QUANTITATIVE ANALYSIS OF IMIDACLOPRID IN ENVIRONMENTAL WATER MATRICES BY SURFACE-ENHANCED RAMAN SPECTROSCOPY
(2023)Neonicotinoids are synthetic pesticides commonly employed in agricultural fields to combat pests. Due to their high water solubility and persistence, they can be transported via percolating water or runoff into groundwater ... -
Rapid Short and Medium Span Bridge Construction Using Innovative Precast Structural Systems
(2010-12-15)The direct costs of bridge construction, such as materials, labor, and equipment are all well known. Recently however the indirect costs such as the cost of traffic disruptions, and construction safety are beginning to ... -
Reaching a Consensus Among Construction Stakeholders: Defining Success and Benchmarking Performance
(2021-12)Executive Summary Despite significant and increasing figures for expenditure and employment which are demonstrative of a successful and growing economic sector, construction still has an industrial struggle with the precise ... -
Recognition Distance and Elongation Ratio for Elongated Horizontal Pavement Markings: A Simulator Study
(2014-05-18)All factors being equal, pavement marking signs are more likely to be detected by drivers than post-mounted signs. Several international manuals/guidelines explicitly state that elongation improves the legibility distance ... -
Reducing Stakeholder Vulnerability to Climate Variability in Southern Peru Using Statistically-Based Prediction and Risk Management Tools
(2018-05-31)Located at a complex topographic, climatic, and hydrologic crossroads, southern Peru is a semi-arid region that exhibits high spatiotemporal variability in precipitation. The economic viability of the region hinges on this ... -
