A Framework To Aid Decision Making For Smart Manufacturing Technologies In Small-And Medium-Sized Enterprises, Purvee Bhatia Jun 2021

A Framework To Aid Decision Making For Smart Manufacturing Technologies In Small-And Medium-Sized Enterprises, Purvee Bhatia

USF Tampa Graduate Theses and Dissertations

The fourth industrial revolution or Industry 4.0 has changed today’s manufacturing scenario. The transition to smart manufacturing technologies has been evolving over the last few years and has recently accelerated due to the pandemic. The need to make manufacturing systems agile, adaptive, resilient, and robust has expediated the adoption and implementation of smart manufacturing technologies.

Despite the interest of manufacturers in smart manufacturing, the adoption rate has been slow due to the lack of decision-making tools that can provide a clear strategic roadmap for effective execution. Small and medium sized enterprises (SMEs) are especially slow in adoption due to the …


Development Of 3-D Printed Hybrid Packaging For Gaas-Mems Oscillators Based On Piezoelectrically-Transduced Zno-On-Soi Micromechanical Resonators, Di Lan Jun 2018

Development Of 3-D Printed Hybrid Packaging For Gaas-Mems Oscillators Based On Piezoelectrically-Transduced Zno-On-Soi Micromechanical Resonators, Di Lan

USF Tampa Graduate Theses and Dissertations

Prior research focused on CMOS-MEMS integrated oscillator has been done using various foundry compatible integration techniques. In order to compensate the integration compatibility, MEMS resonators built on standard CMOS foundry process could not take full advantage of highest achievable quality factor on chip. System-in-package (SiP) and system-on-chip (SoC) is becoming the next generation of electronic packaging due to the need of multi-functional devices and multi-sensor systems, thus wafer level hybrid integration becomes the key to enable the full assembly of dissimilar devices. In this way, every active circuit and passive component can be individually optimized, so do the MEMS resonators …


Large Area Sintering Test Platform Design And Preliminary Study On Cross Sectional Resolution, Christopher J. Gardiner Nov 2017

Large Area Sintering Test Platform Design And Preliminary Study On Cross Sectional Resolution, Christopher J. Gardiner

USF Tampa Graduate Theses and Dissertations

Additive manufacturing involves the layer-wise patterned addition of material to create 3D parts, allowing for parts with complex geometries that traditional subtractive manufacturing processes cannot create, while offering good value for low run production parts by eliminating the cost of tooling. Large Area Sintering is a form of powder based additive manufacturing where entire layer cross sections are heated and fused in a single continuous exposure process. This layer by layer powder sintering process is similar to selective laser sintering, but by heating the cross section at a slower and controllable rate there is an opportunity to achieve tighter control …


Laser Machining And Near Field Microwave Microscopy Of Silver Inks For 3d Printable Rf Devices, Anthony J. Ross Iii Jun 2017

Laser Machining And Near Field Microwave Microscopy Of Silver Inks For 3d Printable Rf Devices, Anthony J. Ross Iii

USF Tampa Graduate Theses and Dissertations

3D printable materials for RF devices need improvement in order to satisfy the demand for higher frequency and lower loss performance. Characterization of materials that have shown improvements of conductor conductivity have been performed. By using a laser machining technique the loss of a 3D printed 2.45 GHz microstrip Square Open Loop Resonator (SOLR) bandpass filter has been shown to improve by 2.1dB, along with an increase in bandwidth from 10% to 12.7% when compared to a SOLR filter that has not been laser machined. Both laser machined and microwaved silver inks have been mapped for conductivity using a Near …
