A Simultaneous Approach for Activity Type and Activity Duration of Disabled People

, M.Sc. Thesis Sharif University of Technology Hajivosough, Shaghayegh Sadat (Author) ; Samimi, Amir (Supervisor)

Abstract

Daily activity patterns that include type and duration of activities are modeled simultaneously in MDCEV models. Conventionally, however, a diverse range of econometric models are used to sequentially model the decisions. Focusing on the disabled individuals, we aimed at comparing the prediction power of the two methods. A three level Nested Logit along with a Hazard model represent the sequential approach, the performance of which is compared to the MDCEV method. A random forest model is applied during the activity type prediction by MDCEV model. With considering 6.35 percent error in random forest model, the results confirmed that simultaneous approach improves activity type prediction by...

Predictive Cordon Pricing to Reduce Air Pollution

, Ph.D. Dissertation Sharif University of Technology Vosough, Shaghayegh Sadat (Author) ; Poorzahedy, Hossain (Supervisor) ; Lindsey, Robin (Co-Supervisor)

Abstract

Traffic is a major contributor to emissions in many large cities with severe air pollution. Experience in London, Milan, and Stockholm shows that charging for the use of roads can be effective in reducing emissions, as well as congestion. This study examines the use of predictive cordon tolls based on weather forecasts to reduce ambient air pollution and congestion. Travelers choose their destinations inside or outside the cordon, and whether to drive or take public transport. Passenger vehicles are divided into three classes according to their emission characteristics, and higher tolls are imposed on more polluting vehicles. The Box model of emission dispersion is used to predict air...

Flexible Solar Cells Based on Nanostructured Tin Perovskite Compounds

, M.Sc. Thesis Sharif University of Technology Arabloo, Shaghayegh (Author) ; Simchi, Abdolreza (Supervisor)

Abstract

One type of solar cell that has gained significant attention among researchers globally and demonstrated considerable efficiency is the lead-based perovskite solar cell. However, due to the high toxicity of lead and its harmful environmental effects, combined with low stability against moisture and oxygen, the widespread application of these cells has been limited. Therefore, extensive research is currently being conducted to eliminate lead from the perovskite structure and develop tin-based perovskite solar cells. In this study, colloidal solutions of CsSnI3 perovskite nanoparticles were processed using the Hot Injection method. By replacing long-chain ligands like oleic acid and oleylamine...

Abstract

This paper concerns with the interfacial tension (IFT), wettability modification and adsorption behavior of a new plant-based surface active agent, Zizyphus Spina Christi, onto sandstone minerals which has been rarely attended in the available literature. Both kinetics and equilibrium adsorption data were obtained from batch mode tests. It was revealed that Freundlich isotherms matched better fit to the equilibrium data which implied that multilayer coverage of Zizyphus Spina Christi onto the sandstone particle surfaces was more likely to occur. Analysis of experimental kinetic data based on intraparticle diffusion model disclosed that the intraparticle diffusion mechanism is not the only...

Abstract

Characterization of viscous fingering in low tension displacements especially for heavy oil surfactant pair in heterogeneous systems is neither straight forward nor well understood. In this work layered porous models containing fractures with different geometrical properties were used and the finger behavior during displacement of LTNS, as a new EOR agent, in heavy oil was quantified. Dynamic propagation of the fingers independent to the type of heterogeneity is well correlated with the dimensionless displacement time in a linearly form. And also, the rate of finger growth is nearly independent to the type of medium heterogeneity. When injection is scheduled through high permeable region in...

Abstract

In oil and gas fields, it is a common practice to flow liquid and gas mixtures through choke valves. In general, different types of primary valves are employed to control pressure and flow rate when the producing well directs the natural gas to the processing equipment. In this case, the valve normally is affected by elevated levels of flow (or velocity) as well as solid materials suspended in the gas phase (e.g., fine sand and other debris). Both surface and subsurface chokes may be installed to regulate flow rates and to protect the porous medium and surface facilities from unusual pressure instabilities.In this study a reliable, novel, computer based predictive model using Least-Squares...

Abstract

A fundamental chemical enhanced oil recovery (EOR) process is surfactant flooding in which the key mechanism is to reduce interfacial tension between oil and the displacing fluid and hence mobilizing the trapped oil. Surfactant loss by adsorption is one of the most important criteria that governs the economics of the surfactant flooding methods. In addition to this, detrimental effects and high price of currently used surfactants cause EOR process so expensive and unfeasible. This study is aimed to introduce a novel kind of plant based surfactant which is extracted from Zizyphus Spina-Christi tree. In addition, equilibrium adsorption behavior of this novel biosurfactant in aqueous solution...

Abstract

Over the years, accurate prediction of dew-point pressure of gas condensate has been a vital importance in reservoir evaluation. Although various scientists and researchers have proposed correlations for this purpose since 1942, but most of these models fail to provide the desired accuracy in prediction of dew-point pressure. Therefore, further improvement is still needed. The objective of this study is to present an improved artificial neural network (ANN) method to predict dew-point pressures in gas condensate reservoirs. The model was developed and tested using a total set of 562 experimental data point from different gas condensate fluids covering a wide range of variables. After a...

Abstract

Snakebite envenoming is an important cause of preventable death. The World Health Organization (WHO) set a goal to halve snakebite mortality by 2030. We used verbal autopsy and vital registration data to model the proportion of venomous animal deaths due to snakes by location, age, year, and sex, and applied these proportions to venomous animal contact mortality estimates from the Global Burden of Disease 2019 study. In 2019, 63,400 people (95% uncertainty interval 38,900–78,600) died globally from snakebites, which was equal to an age-standardized mortality rate (ASMR) of 0.8 deaths (0.5–1.0) per 100,000 and represents a 36% (2–49) decrease in ASMR since 1990. India had the greatest number...
