Accounting For Midblock Pedestrian Activity In The Hcm 2010 Urban Street Segment Analysis, Albert Forde

Dissertations

The Urban Street segment analysis Chapter of the 2010 Highway Capacity Manual (HCM 2010) provides a methodology for analyzing automobile performance on signalized roadway segments within an urban roadway network. The methodology involves applying a platoon dispersion model to: a) predict the vehicle arrival flow profiles at a downstream signalized intersection; b) use the predicted arrivals to compute the proportion of vehicle arrivals on green; and c) subsequently estimate the delay, travel speed and Level of Service (LOS) under which the segment operates. Vehicles arriving during the red interval at a signalized intersection generally accumulate and form a platoon. When …

Structural Health Monitoring Of Bridges Using Wireless Sensor Networks, Seyed Behrad Ghazi Sharyatpanahi

Theses

Structural Health Monitoring, damage detection and localization of bridges using Wireless Sensor Networks (WSN) are studied in this thesis. The continuous monitoring of bridges to detect damage is a very useful tools for preventing unnecessary costly and emergent maintenance. The optimal design aims to maximize the lifetime of the system, the accuracy of the sensed data, and the system reliability, and to minimize the system cost and complexity

Finite Element Analysis (FEA) is carried out using LUSAS Bridge Plus software to determine sensor locations and measurement types and effectively minimize the number of sensors, data for transmission, and volume of …

Modeling Biodegradation Settlement Of Municipal Solid Waste (Msw) Based On Measurement Of Landfill Gas And Degradable Solids In Leachate Recirculated Bioreactors, Vatsal Atulkumar Shah

Dissertations

The purpose of this work is two-fold: 1) to understand the phenomenon of the biodegradation process of municipal solid waste (MSW) in leachate recirculated bioreactors, and 2) to create a realistic predictive model based on this understanding which is capable of supporting a laboratory-to-field relationship for bioreactor landfills. Biodegradation is best described by loss of mass; however, primary researchers have assumed the phenomenon to be purely volume loss and modeled best by mechanical processes using a conservation of energy approach. It is suggested that the phenomenon requires a fundamental understanding of biodegradation process which results in a loss of mass, …

Expert System For Energy Optimization Of Buildings Using Sustainable And Resilient Strategies, Victoria Ann Scala

Dissertations

An expert system is developed using the science of heuristics to better model energy usage in existing commercial buildings and to predict future improvements more accurately. The software performs an initial audit analysis of all the major building systems including building envelope, HVAC, lighting, office equipment and appliances, water and hot water, and waste handling. A novel feature of the expert system is that it analyzes energy flow within the building more interactively and cohesively, as opposed to looking at each system individually as do most energy analysis tools on the current market. Both forward and backward chaining strategies are …

Assessment Of Flood Protection Strategies For Combined Critical Infrastructure Failure And Hurricane/Storm Surge Events In The Meadowlands Area, Nisharg Dipakkumar Dalwadi

Theses

As a result of a wide-reaching comprehensive post-Sandy NJIT project entitled "Flood Mitigation Engineering Resource Center (FMERC)", a detailed investigation of alternative measures for flood mitigation in the Meadowlands area was completed in June 2014. The project involved the assessment of flood impacts, and the evaluation of a range of structural and non-structural capital improvement measures, maintenance, operations and regulatory measures, and broad system design and redundancy measures.

The basic objective of this thesis is to develop an innovative procedure for the enumeration and simulation of probability-weighted combined events, e.g., Oradell dam failure under various scenarios (sunny day, water level, …

Fates Of Spilt Oil And Factors Affecting The Bio-Degradation Of Oil: A Review, Amogh-Ranganath Chakravarthy

Theses

The usage of crude oil and its products is increasing; in turn, the number of spills is also going up. The inland spills are the more recurrent spills in the U.S today. This review article deals with the weathering of oils, which commences just after oil spills into the environment with various processes such as evaporation, dissolution, photo-oxidation, dispersion, emulsification and bio-degradation along with other possible fates. Biodegradation is one of the most significant processes of weathering which depends on oil physical and chemical characteristics, environmental characteristics, pH, salinity and oil concentration. There is a range of oil concentration for …
