Show moreIn a hybrid electric vehicle (HEV) with parallel powertrain, the system can be controlled by splitting the required power between the electric propulsion machine and internal combustion engine (ICE) to meet specific goals related to fuel consumption, efficiency, performance, and/or emissions. This power splitting scenario, which is of great hybridization importance, is in fact the control strategy or energy management of the hybrid vehicle. Performance of the system depends on the control strategy, which needs to be robust, stable, reliable, and independent from uncertainties. This Ph.D. research is focused on model based control strategies, which are proposed for parallel hybrid powertrains, showing significant advantages in performance and fuel economy. If a model based control strategy is used to develop the hybrid power management algorithm, the accuracy of the model data needs to be high for proper control. Therefore, this type of management method is parameter sensitive. Implementing system identification features into this algorithm reduces the effect. As a result, the proposed controller algorithm learns the existing component parameters while operating. Furthermore, combining the base controller with an online tuner, which simultaneously optimizes the controller for current conditions, will improve the performance of the power management. In addition, this Ph.D. thesis presents a novel neural adaptive equivalent consumption minimization strategy (ECMS) and applies it to a hybrid representative sport utility vehicle (SUV) with parallel powertrain. The ECMS is a model based optimal control strategy and is based on the minimization of both fuel consumption and battery charge usage by introducing the equivalent coefficient between them. Proper operation of the controller depends on the accuracy of the model. It also depends on the correct selection of the equivalent coefficient. In this Ph.D. thesis, specific neural network structures are proposed for both coefficient selections by drive cycle recognition and for precise model building by system identification. This thesis also presents a novel fast solution method of ECMS algorithm for real time applications.

Show moreA flow direction collar is positionable in an electrical zone sensing apparatus with an elongated bore therein disposed in substantial alignment with an aperture through which particles carried by a liquid pass while being electrically sensed. The collar is positioned immediately upstream of the aperture to cause a directional flow of the liquid along a path substantially parallel to a longitudinal axis for the aperture. The flow through the collar directs the particles to flow along paths substantially parallel to the aperture axis thereby reducing the turbulence about the particle created by abrupt changes in velocity. Preferably, the collar includes a housing for telescoping on the bottom of a detection tube.

Show moreDiabetes is one of the prevalent diseases in the USA, which affects the lives of millions of people. In 2010 only, there was a total of 234,051 deaths linked to diabetes in the USA. Research related to preclinical and clinical assays are always costly and time consuming. Modeling is a helpful method to reduce the cost of clinical experiments and accelerates the discovery and improvement of new therapies. This research is focused on the development of a high performance agent-based model simulating the pathogenesis of Type 1 diabetes mellitus in pancreas. The whole immune response takes place in three compartments, pancreatic lymph node, circulation, and pancreas. A significant part of the complex interactions leading to Type 1 diabetes takes place in the pancreatic tissue. Therefore, the focus was placed on the islets of Langerhans in the pancreas, and the interaction of CD8+ T cells and Beta cells were modeled. T cell behavior was incorporated as rules in this model such as activation, migration, proliferation, apoptosis, and cytotoxicity. Likewise Beta cell death and regeneration under the T cell attack were modeled. The model is able to capture the trends of T cell and Beta cell variations during the disease progression and portrays the role of CD8+ T cells in the process. It is expected that, with the addition of other immune system and pancreatic tissue components, the model will be a valuable tool for the planning of clinical studies.

Show moreA method for removing a contaminant from a treatment region of a contaminated region of a site in the earth having water therein and being contaminated with the contaminant includes heating the earth by establishing an electric field through the treatment region. The electric field gives rise to an electric conduction or displacement current through the treatment region. The electric current electrically heats at least a portion of the treatment region to a temperature below the boiling point of water to evaporate the water. A vacuum is drawn in a nether region of the site to collect water vapor evolved from the water and contaminant vapor evolved from the contaminant by movement of air from the surface of the earth, while the water vapor strips the contaminant from the earth. The contaminant vapor is disposed of in an innocuous manner.

Show moreA morphologically structured model is proposed to describe penicillin production in fed-batch cultivations. The model accounts for the effects of dissolved oxygen on cell growth and penicillin production and variations in volume fractions of abiotic and biotic phases due to biomass formation. Penicillin production is considered to occur in the subapical hyphal cell compartment and to be affected by availability of glucose and oxygen. As it stands, the model provides a wide range of applicability in terms of operating conditions. The model has been tested for various conditions and has given satisfactory results. A series of glucose feeding profiles have been considered to demonstrate the capabilities of the proposed model. It is concluded that the model may be valuable for the interpretation of experimental data collected specifically for metabolic flux analysis during fed-batch cultivation because the elements of measured specific production rates are determined from measurements of the concentrations of the components and their mass balances. The proposed model may be further used for developing control strategies and model order reduction algorithms

Title: P21 IS A BIOMARKER OF CELL FATE AFTER UV IRRADIATION

Show moreUV irradiation can cause DNA damage, which leads to either cell cycle arrest or apoptosis. As a major transcriptional target of p53 protein in response to DNA damage, p21 protein plays critical roles in both cell cycle arrest and apoptosis. However, the specific range of UV doses and functions of p21 protein leading to the determination of cell fate in human androgen-independent prostate cancer cells has not been completely elucidated. Here, we show that low doses of UV irradiation (< 40 J/m2) induced cell cycle arrest with up-regulation of p21 protein. However, high doses of UV irradiation (> 60 J/m2) can induce apoptotic cell death as indicated by caspase-3 activation, which is also consistent with apoptotic morphological changes. Interestingly, p21 protein is degraded at early time course of high-dose UV irradiation-induced apoptosis, pretreatment of proteasome inhibitor MG132 which can block p21 degradation but partially inhibits apoptotic cell death. Consistently, similar results were obtained in both 104-R1 cells and 104-IS cells. Taken together, the results suggest that there is a narrow window of UV doses range that serves as a “switch” point, in which cells make a decision: either cell cycle arrest or cell death. p21 protein serves as a good indicator for both cell cycle arrest and apoptotic cell death post-UV irradiation in human androgen-independent prostate cancer cells. Therefore, p21 may be a potential therapeutic target in prostate cancer.

Show moreThe present invention is directed to a novel steamflooding process which utilizes three specific stages of steam injection for enhanced oil recovery. The three stages are as follows: As steam is being injected into an oil-bearing reservoir through an injection well, the production rate of a production well located at a distance from the injection well is gradually restricted to a point that the pressure in the reservoir increases at a predetermined rate to a predetermined maximum value. After the maximum pressure has been reached, the production rate is increased to a value such that the predetermined maximum pressure value is maintained. Production at maximum pressure is continued for a length of time that will be unique for each individual reservoir. In some cases, this step of the steamflooding process of the invention may be omitted entirely. In the third stage of the steamflooding process of the invention, production rates at the producing well are increased gradually to allow the pressure to decrease down from the maximum pressure value to the original pressure value at the producing well. The rate of pressure reduction will be unique for each reservoir. After completing stage three, the three stages can be repeated or the steamflood may be terminated as considered desirable.

Show moreIn the recent years, anisotropic metallic nanoparticles have drawn much attention because of their unique optical properties. Particularly, gold and silver nanorods show great potential in extensive applications such as health care, food storage, drug delivery, biosensor, and cancer treatment. Among a variety of nanorods synthesis methods, the seed-mediated growth approach stands out due to its mild and convenient experimental conditions. However, there exist two defects of this method, the poor reproducibility and low yield of nanorods. In order to create nanoparticle systems of reproducible quality in high yields, a deeper understanding of the mechanism of nanorods formation as well as identifying the more important variables is necessary. In this study, the original seed-mediated growth method has been modified to promote the reproducibility and yield of nanorods. Effects of CTAB concentration and ages of growth solution have been investigated in the nanorods formation process. The results suggest that a high concentration of CTAB is not necessary for the growth process and the age of growth solution can affect the optical performance of nanorods. In a brief survey on the stability property of nanorods, it shows that the degradation rate decreases with increasing concentrations of CTAB.
