Show moreThis study analyzes and designs a logistics network for the distribution of four brands of passenger cars in the Great Lakes region. The study evaluates four types of distribution scenarios. Alternative 1 analyzes direct shipment method with only truck transportation mode from one distribution center located in the Chicago city to the cities in the Great Lakes region. Second alternative analyzes direct distribution method using multimodal transportation modes (railway and truck) from one distribution center to the cities included in this project. Third alternative analyzes peddling distribution method with only truck transportation mode from one warehouse to the project cities and the fourth alternative analyzes car distribution using direct shipment method with only truck transportation mode from two warehouses, where the main warehouse is located in Chicago city and the second warehouse is located in Indianapolis city. The analyses are conducted in order to determine the most cost-effective scenario for passenger car distribution in the Great Lakes region. The results of the study show that the most cost-effective scenario for passenger car distribution in the Great Lakes region includes using direct shipment method with multimodal transportation mode having one warehouse. However, this scenario has many uncovered sections such as we assumed that the warehouse and all destinations are located near to the railway yard and we do not need to transport cars from warehouse to the railway yard or from railway yard to the dealer by car huller truck/trailer. But in most of the time a railway yard and distribution center or a car dealership is not located in the same place or close to each other which in reality could increase the total cost for the logistics network. The second optimal cost provides the Alternative 1, which uses direct shipment method with only truck transportation mode and having one warehouse. This scenario is more practical and possible to use in reality without having significant changes in the total cost.

Show moreThe safe storage of natural resources, such as liquefied natural gas or propane, is essential to the public and companies that distribute these resources. Large diameter, double walled cylindrical storage tanks are the typical structure used to store these natural resources. One of the design factors that commonly govern the structural integrity of the tank is the design seismic response spectra. A component of the tank that is not given much consideration in the industry codes is the suspended insulated deck. The purpose of the deck is to provide a layer of insulation just above the liquid level of the product. This helps control the release of gases that boil off from the product. Despite this deck being made of thin plate material, this can be a considerable mass on large diameter tanks once the insulation and deck stiffeners are accounted for. The supports for the deck are typically one-half inch or sixteen millimeter square rods, which do not provide much lateral resistance. The concern this thesis investigates is what occurs to the suspended deck during an earthquake. By treating the outermost ring of rods as a moment frame, the summation of each rod’s lateral stiffness provides the total deck stiffness and natural period of the structure as a single-degree-of-freedom system. It is determined the standard design is likely to collide with other vital components of the tank under certain seismic events. In order to prevent the deck from potentially damaging these components, the conservative route is to increase the stiffness of the deck until the displacements are within an allowable range. viii This is done by installing a tank specific number of braced frames around the outer perimeter of the deck. The above procedure is a simple method to ensure there are no unexpected collisions between tank components. More time consuming methods, such as finite element analysis may show that the standard design can sufficiently withstand any collisions. However, the ability to provide a quick, easy solution with minimal added construction materials is a considerable advantage when ensuring the safety of the storage tank.

Show moreTemporary structures are structures that are set up for applications in relatively short time periods, most notably category of which are scaffolds that are built in two types: supported and suspended. Tube and coupler scaffolding systems are supported types and are commonly used in nuclear industry’s applications. This study evaluates the behavior of this type of scaffolding system due to the effect of dead, live, i.e. weight of workers and equipment, and lateral earthquake loads applied on the structure. Consistent with OSHA dimensional requirements, six different configurations ranging from 1 to 3 stories and 1 to 2 bay scaffoldings have been selected for this study. Using a finite element analysis, the significance of all gravity loads, as well as potential seismic loads on the safety and stability of aforementioned scaffold types was studied. The seismic acceleration level at which the failure occurs was determined for four failure criteria. These criteria are: (1) the structural member yield failure; (2) the structural member buckling failure; (3) the system sliding failure; and (4) the system overturning (tip-over) failure. The analysis results show that the most critical failure mode for all configurations of tube and coupler scaffolds studied in this thesis occurred due to instability and as result of sliding. No overstress or buckling failure was observed to occur prior or concurrent to this failure. This finding reaffirms that this type of scaffolds has considerable sufficient capacity to resist their intended loads yet are vulnerable to instability because of sliding. With regards to the effect of number of bays and stories on the critical earthquake level, it was observed that as the number of scaffold stories increases, the critical earthquake level becomes smaller except for the case of the 1-bay scaffold for the 2- and xii 3-story configurations. Addition of an extra bay to a simple 1-bay scaffold configuration does not considerably improve the earthquake level at which the sliding failure occurs. With regards to time of failure, addition of stories to a scaffold configuration delays the failure occurrence in all cases except for the case of the 2-bay scaffold and addition of a bay does significantly delay the occurrence of failure for 1- and 2-story scaffolds, about 6 second for 1-story scaffolds, and 8 seconds for 2-story scaffolds. However, this improvement is negligible for 3-story scaffolds. In general, addition of a bay postpones the failure time. The evaluation of stress levels in all various scaffolding elements suggests that increasing the number of bays and/or stories does not generally affect the induced stresses in beams. In addition, the study shows that buckling and overturning (uplift) effects have very minimal effect on the failure of tube and coupler scaffolds.

Show moreReports suggest that Chicago is one of the leading US cities with respect to sustainability and, in order to promote sustainability in a city like Chicago, it is imperative that the residents are aware of factors associated with sustainable development and contribute towards its advancement. Majority of the research conducted so far, does not examine the non-expert level of sustainability understanding. This thesis investigates the public literacy on sustainable development by conducting a survey and analyzing the generated database. The statements posed in the survey do not demand technical education but assess the non-expert resident literacy of sustainability by asking relevant subjects. The survey consists of four demographic questions (participants‟ gender, age, level of education and annual income), fifteen conceptual statements and five opinion statements, based on sustainability. The aim is to find a relation, if any, between the respondents‟ demographics and their responses to the survey. The database generated from the survey of 353 randomly selected individuals, is analyzed by four different statistical methods, which are arranged in increasing order of complexity – (i) descriptive statistics and z-test for proportions, (ii) contingency tables and Pearson chi-square test, (iii) exploratory factor analysis and (iv) multinomial logistic regression. The outcome of the statistical analyses suggests that approximately 50% of the participants have accurately responded to the survey and the non-expert resident does not know the definitions to pertinent sustainability concepts. Additionally, survey responses have a strong association with the participants‟ age. There is a weak association between answers and the respondents‟ gender and annual income. In spite of higher than average participants with a college degree, the level of education has a negligible relation with survey responses. Thus, it is necessary to increase the awareness and educate non-experts about sustainable development. It is promising to observe that the responses to the opinion statements suggest that individuals are willing to contribute towards sustainability provided they are educated about it. Nonetheless, the willingness to contribute requires action and without societal support, it is not possible to promote sustainability, which requires increased understanding and knowledge and willingness to act appropriately.

Show moreSimultaneous removal of dominant forms of nitrogen and phosphorous present in secondary effluents was studied with reactive filtration as the treatment method. The selected media for filter bed included Granular Ferric Hydroxide (GFH), Calcite (C), Silica Sand (S), and Activated Alumina (A). The focus was to evaluate the performances of media blends GFH-C-S and A-C-S for removal of sRP and sNO3-N in lab scale batch and column experiments using secondary effluents provided by Calumet Water Reclamation Plant. The media blends performed better for sRP removal than sNO3-N removal with A-C-S being outperformed by GFH-C-S in batch experiments, and hence was not used for column experiments. The removal kinetic study using GFH-C-S showed 100% sRP removal rate and 45% NO3-N removal rate for an optimal contact time of 2 minutes, with latter showing gradual desorption after initial instant adsorption. The optimal adsorbent dosage for sRP was found to be 15g (1:1:1) whereas for NO3-N, the removal rates increased with an increase in adsorbent dosage. Column experiments with GFH-C-S gave an adsorption capacity of 1.8 mg/g for an equilibrium concentration of 0.1 mg P/L with breakthrough occurring after a throughput of 603 bed volumes.

Chemical phosphorus (P) removal is commonly implemented in wastewater treatment to remove P to very low levels (
Show moreChemical phosphorus (P) removal is commonly implemented in wastewater treatment to remove P to very low levels (<0.1 mg P/L). The dose of precipitant (Al or Fe) needed is several times the stoichiometric dose in order to achieve a filtered effluent level of < 30 μg TP/L. The mechanistic basis for P removal using chemical precipitant addition is generally considered to be more than simple precipitation. The role of adsorption and/or complexation in removal of reactive or unreactive phosphorus to the already formed chemical precipitates or complexes has been investigated. Potential operational efficiency gains resulting from age of chemically precipitated solids and the recycle of these solids to the process stream was undertaken at the Iowa Hill Water Reclamation Facility which employs the DensaDeg® process (IDI, Richmond, VA) for tertiary chemical P removal. The effect of solids age was found to be insignificant over the solids retention time of 2 to 8 days, indicating that the solids were unaffected by the aging effects of decreasing porosity and surface acidity, and that the bulk of solids were retained in the clarifier blanket, hence providing no advantage in the removal mechanisms from increased concentration of solids. When solids recycle was redirected from the traditional location of the flocculation reactor to a point just prior to chemical addition in the chemical mixing reactor, lower effluent soluble P concentrations at lower molar doses of aluminum were achieved. At laboratory scale, the “spent” or “waste” chemical sludge showed high capacity and rapid kinetics for P sorption from real wastewater effluents. A number of scenarios were tested and the wide range of parameter values indicate that the sorption reaction is rather specific to the sludge and the process water matrix. x Saturation concentrations were in the range of 8 to 29 mg soluble reactive P/g solids. Higher saturation concentrations were found at higher temperatures. Ambiguous results were obtained for the effect of sludge age on capacity, implying dependence on either aging conditions or sample matrices. In all instances alum sludge produced without a coagulant aid polymer had a much higher capacity for P sorption than polymer based sludge. The reaction reached equilibrium in less than 10 minutes with 50% or greater removal within the first minute. Removal reactions were modeled well by nth order equations with n 3 and by exponential data fitting. Modeled as a sorption process, the pseudo-second order model presented by Ho and McKay in 1999 proved to be an excellent fit. Second order rate constants ranged approximately from 0.1 to 6 (g mg-1 min-1) depending on the P fraction examined, age of sludge, reaction temperature, and presence or absence of coagulant aid polymer in the sludge.
