An Engineering Approach For Evaluating The Lifetime Experience Of Sex Trafficking Victimization, Kimberly Starr Nagulpelli

Dissertations

This research is an original approach that applies industrial engineering and operations research tools to the sociological problem of sex trafficking victimization. Such an approach enables quantitative evaluation of the impacts on an individual’s lifetime by anti-trafficking efforts and public policies.

A fully interconnected, lifetime model for the experience of sex trafficking victimization is defined as the result of a comprehensive review of literature. Beginning with victimization risk, the defined model is an anticipatory tool to understand the incidences and consequences to individuals during their lifetime. This research develops the model further into a Discrete-Time Markov Chain (DTMC) with definitions …

Study Of Sustainable Development In Paper, Printing And Packaging Material Applications To Support Circular Economy, Prashant Ramesh Kotkar

Dissertations

To support circular economy and sustainability, the use of suitable material in paper, printing, and packaging industries, for several types of industrial printing material and printed product applications, plays a significant role for end user applications. Several types of packaging printing materials, specifically those finished with different printing technologies and exposed to different environmental conditions are targeted.

The purpose of this research study is to improve design and evaluation for paper, printing, and packaging material sustainability in end-user applications, to deal with the addressed sustainability issues brought by the paper, printing and packaging products end user groups. As the impacts …

Dual-Cure Benzoxazine Networks For Additive Manufacturing, Jeremy Weigand

Dissertations

The research presented addresses the design of novel materials for additive manufacturing through a dual-cure approach that combines UV initiated free-radical polymerization of an acrylic network combined with the thermally initiated ring opening polymerization of a benzoxazine network. This work is split into three primary sections: the first and second sections focus on the synthesis and characterization of networks based on dual-cure BOX monomers, while the third develops simulation tools to further investigate thermoset networks prepared via additive manufacturing. A novel 3D printing formulation based on a multifunctional benzoxazine (BOX) monomer possessing both photo and thermally polymerizable functional groups is …

Gravure Printability Of Indium Tin Oxide Nanoparticles On Glass And Pet Films For Applications In Printed Electronics, Dania Awni Alsaid

Dissertations

The advancements in the field of solution processable electro-active materials and their ability to be printed on different substrates have led to the evolution of printed electronics. In this field, electronic components are manufactured with conventional printing methods. Transparent electrodes made from indium tin oxide (ITO) are part of many electronic devices. Currently in industry, highly conductive ITO films are prepared by sputtering. The sputtering and then patterning of ITO films is a sophisticated process that consumes high energy, generates waste and produces films with limited flexibility. Therefore, there is a need to investigate processing methods for creating ITO films …

Inkjet Printability Of Electronic Materials Important To The Manufacture Of Fully Printed Otfts, Sooman Lim

Dissertations

In this study, the inkjet printability of materials important to fabricating OTFTs was researched. In order to understand the jetting evolution of inkjet printed inks, simulations were performed with a nano copper and nano particle silver ink. To predict the inkjettability of the nano copper ink, Z and Oh numbers at different temperatures were determined. The results from the simulation studies were compared to experimental results obtained using a Dimatix inkjet printer. For the semiconductor ink, the inkjet printability of two organic semiconductors, P2TDC17FT4 (poly[(3,7-diheptadecylthieno[3,2-b]thieno[2',3':4,5]thieno[2,3-d]thiophene-2,6-diyl)[2,2'-bithiophene]-5,5'-diyl] dissolved in 1,2-dichlorobenzene and P3HT (poly-3 hexylthiophene) were compared to determine the relationship between drop …
