Advisor: Dr. Naeim Henein

Major: Mechanical Engineering

Degree: Master of Science

Although diesel engines are considered the best powerhouses for their heavy-duty

capabilities, concerns have been raised because of their emission issues. Alternative

fuels like jet fuels can be substitute to them for improved efficiencies. The Department Of

Defense uses JP8 for their combat vehicles under their Single Fuel Concept for a better

logistic supply chain. However, due to the projected …

Kinematic Modeling Of An Automated Laser Line Scanning System, Kiran Sunil Deshmukh

Wayne State University Theses

This research work describes the geometric coordinate transformation in an automated laser line scanning system caused by movements required for scanning a component surface. The elements of an automated laser scanning system (robot, laser line scanner, and the component coordinate system) function as a mechanical linkage to obtain a trajectory on a component surface. This methodology solves the forward kinematics, derives the component surface, and uses inverse kinematic equations to characterize the movement of the entire automated scanning system on point trajectory. To reach a point on the component, joint angles of robot have been calculated. As a result, trajectory …

Enhancement Of Cancer Vaccine Efficacy Via Nanoparticle Or Molecular-Based Adjuvants, Myunggi An

Wayne State University Theses

Adjuvants are immunomodulators which enhance immune responses to vaccines. However, parenteral administration of unformulated adjuvants fails to reach lymph nodes (LNs), the anatomic organ where the primary functions of immune cells are orchestrated. The LN-targeting delivery plays the key roles in promoting immune activation and has the great potential to transform disease treatment. The main goal of this thesis is to develop efficient vaccine delivery systems to target therapeutics into draining lymph nodes (dLNs) for ensuring their immunostimulatory activity. We introduced therapeutic applications of activating TLR9 with synthetic CpG oligodeoxynucleotide (ODN) agonists in nanoparticle or molecular form to activate immune …

Experimental Strain Measurement In Ultrasonic Welding Of Battery Tabs, Chen Chen

Wayne State University Theses

Lithium-ion battery is one the most popular types of batteries currently used in electric

vehicles. To meet the power requirement, hundreds of Lithium ion battery cells are connected together before being assembled into a battery pack. Ultrasonic welding is the most widely used joining technology to connect battery cells together. In an ultrasonic welding process, high frequency oscillation is used to generate small relative motions between sheet metals to be welded, and produce solid-state bonds between the sheet metals clamped under pressure. One of the major issues for battery pack ultrasonic welding is that sometimes the welding process damages the …

Quantitative Assessment Of Brain Iron Content As A Function Of Age Using Magnetic Resonance Imaging, Kiarash Ghassaban

Wayne State University Theses

As the most abundant transition metal in the brain, iron is known to play a key role in a variety of functional and cellular processes. Recent in vivo and post-mortem studies have shown that the levels of iron deposition in the brain, particularly in deep gray matter nuclei, vary as a function of age. On the other hand, elevated iron has also been associated with some neurodegenerative diseases such as Multiple Sclerosis (MS) and Parkinson’s disease (PD) among others.

Magnetic Resonance Imaging (MRI) is a widely used non-invasive and non-ionizing imaging modality which is sensitive to magnetic properties of materials …

Induction Local Softening Of Advanced High Strength Steel, Jorge Saul Cisneros

Wayne State University Theses

This study was to determine the important parameters regarding induction local softening of dual phase steel with improved manufacturability for autobody stamping. Samples were inductively heat-treated, and then tested using micro hardness test, tensile test, microstructure analysis, and x-ray diffraction analysis. It was found that above 800oC there was a significant reduction in hardness. The cooling rate was found to be the most important parameter affecting the final properties of the steel. The tensile test showed a significant increase in total elongation with a small reduction in ultimate tensile strength. These factors led to the ultimate increase in formability. X-ray …

Implementation Of Camera Arm Control By An Oculus Rift On A Da Vinci Surgical System Simulation, Hamid Sadeghi

Wayne State University Theses

Camera control methods play a significant role in remote surgery. Two methods have been developed to control the camera arm of the da Vinci Surgical System: a standard clutch-based method for manual movement of the camera and an autonomous camera (auto-camera) method. In the standard method, the surgeon positions the camera manually using a pair of hand controllers. This happens frequently during the surgery and may serve as a distraction during surgical procedures. The second method was developed in order to help surgeon to remove the issue mentioned in the standard method. Auto-camera method enables the system to move the …

Targeted Delivery Of Nrf2 Sirna Using Modular Polymeric Micellar Nanodelivery System For Efficient Target Gene Knockdown In Hepatocellular Carcinoma, Shaimaa Mohamed Ibrahim Yousef

Wayne State University Theses

Tumor selective drug delivery as well as chemotherapy associated multi drug resistance (MDR) pose tremendous hurdles for effective cancer therapy. In this regard, designing multifunctional nanocarriers loaded with drug/gene payloads and engineered with tumor targeting ligands can serve as a modular platform for targeted drug/gene delivery. In this study we undertook the synthesis of a self-assembling block copolymer constructed using poly(styrene-co-maleic anhydride, partial iso-octyl ester) (SMAPIE) and branched polyethylenimine (PEI) as building blocks and evaluated its micelle forming ability, siRNA complexation and siRNA delivery potentials. In addition, we engineered galactosamine decorated nanomicelles using modular “click” chemistry based approaches for evaluating …

Novel Design And Synthesis Of Transition Metal Hydroxides And Oxides For Energy Storage Device Applications, Peifeng Li

Wayne State University Theses

Supercapacitors (SCs) and Li-ion batteries (LIBs) are two types of important electrical energy storage devices with high power density and high energy density respectively. However, to satisfy the increasing demand of high-performance energy storage devices, the energy density of SCs and power/energy densities of LIBs have to be further improved. The exploration, research, and development of electrode materials with high-performance for applications in SCs and LIBs are still needed to meet the ever-increasing demand on energy and power densities. Herein, the amorphous Ni-Co-Mo ternary hydroxides nanoflakes for SCs and oxides nanoflakes for LIBs with ultrathin stature, abundant open spaces, and …
