Developing countries suffer from various health challenges due to inaccessible medical diagnostic laboratories and lack of resources to establish new laboratories. One way to address these issues is to develop diagnostic systems that are suitable for the low-resource setting. In addition to this, applications requiring rapid analyses further motivates the development of portable, easy-to-use, and accurate Point of Care (POC) diagnostics. Lateral Flow Immunoassays (LFIAs) are among the most successful POC tests as they satisfy most of the ASSURED criteria. However, factors like reagent stability, reaction rates limit the performance and robustness of LFIAs. The fluid flow rate in LFIA significantly affect the factors mentioned above, and hence, it is desirable to maintain an optimal fluid velocity in porous media.

The main objective of this study is to build a statistical model that enables us to determine the optimal design parameters and ambient conditions for achieving a desired fluid velocity in porous media. This study mainly focuses on the effects of relative humidity and temperature on evaporation in porous media and the impact of geometry on fluid velocity in LFIAs. A set of finite element analyses were performed, and the obtained simulation results were then experimentally verified using Whatman filter paper with different geometry under varying ambient conditions. Design of experiments was conducted to estimate the significant factors affecting the fluid flow rate.

Literature suggests that liquid evaporation is one of the major factors that inhibit fluid penetration and capillary flow in lateral flow Immunoassays. The obtained results closely align with the existing literature and conclude that a desired fluid flow rate can be achieved by tuning the geometry of the porous media. The derived statistical model suggests that a dry and warm atmosphere is expected to inhibit the fluid flow rate the most and vice-versa.

This dissertation focuses on three different efficiency enhancement methods that are applicable to handset applications. These proposed designs are based on three critical requirements for handset application: 1) Small form factor, 2) CMOS compatibility and 3) high power handling. The three presented methodologies are listed below:

1) A transformer-based power combiner architecture for out-phasing transmitters

2) A current steering DAC-based average power tracking circuit for on-chip power amplifiers (PA)

3) A CMOS-based driver stage for GaN-based switched-mode power amplifiers applicable to fully digital transmitters

This thesis highlights the trends in wireless handsets, the motivates the need for fully-integrated CMOS power amplifier solutions and presents the three novel techniques for reconfigurable and digital CMOS-based PAs. Chapter 3, presents the transformer-based power combiner for out-phasing transmitters. The simulation results reveal that this technique is able to shrink the power combiner area, which is one of the largest parts of the transmitter, by about 50% and as a result, enhances the output power density by 3dB.

The average power tracking technique (APT) integrated with an on-chip CMOS-based power amplifier is explained in Chapter 4. This system is able to achieve up to 32dBm saturated output power with a linear power gain of 20dB in a 45nm CMOS SOI process. The maximum efficiency improvement is about ∆η=15% compared to the same PA without APT. Measurement results show that the proposed method is able to amplify an enhanced-EDGE modulated input signal with a data rate of 70.83kb/sec and generate more than 27dBm of average output power with EVM<5%.

Although small form factor, high battery lifetime, and high volume integration motivate the need for fully digital CMOS transmitters, the output power generated by this type of transmitter is not high enough to satisfy the communication standards. As a result, compound materials such as GaN or GaAs are usually being used in handset applications to increase the output power. Chapter 5 focuses on the analysis and design of two CMOS based driver architectures (cascode and house of cards) for driving a GaN power amplifier. The presented results show that the drivers are able to generate ∆Vout=5V, which is required by the compound transistor, and operate up to 2GHz. Since the CMOS driver is expected to drive an off-chip capacitive load, the interface components, such as bond wires, and decoupling and pad capacitors, play a critical role in the output transient response. Therefore, extensive analysis and simulation results have been done on the interface circuits to investigate their effects on RF transmitter performance. The presented results show that the maximum operating frequency when the driver is connected to a 4pF capacitive load is about 2GHz, which is perfectly matched with the reported values in prior literature.

Impermanence is constant within the world humans live in; the physical environment is ever-changing, parallel with human evolution. Although the moment of a human lifespan is fleeting in comparison to their surrounding landscapes, the evidence of movement that lapses through time and space in relation to body and place reveals a hidden dance that soars across the history of humankind. This document explores the relationship between moving bodies and various environments, specifically how an individual’s perception of place influences the way people dance. Given the author’s background as a choreographer, performer, and filmmaker, the goal and method of this document is to understand the author’s and his ensemble of dancers’ perceived senses within a given geographic environment and to merge personal dialect in an artistic product. Ultimately, what was found was translating into an evening-length, movement-centered presentation.

The author's curiosity with foreign landscapes and his exploratory spirit are the driving forces for this project. Before arriving at the thesis topic, the author knew that environmental exploration and dance would be at the forefront of the research. Similar to a museum exhibition context, this document yearns for variety, and studies the environments through an event that encapsulates it all. This document explores the author’s multiple artistic interests in photography, film, and live performance, all of which were presented in a single event.

This research study aimed to develop, implement, and evaluate the effectiveness of a dance wellness educational curriculum administered in a university-level dance classroom. Using a mixed methods design involving a pre-test/post-test performance assessment and document analysis for qualitative data, this study asked two questions: 1) How does participation in a semester-long course on Group Fitness Instruction and dancer wellness increase participants’ comprehension of exercise science and fitness instruction concepts? 2) How does participation in a semester-long course on Group Fitness Instruction and dancer wellness impact participants’ personal approaches to teaching, training, and wellness? Results showed that the post-test scores were significantly higher than pre-test scores, and qualitative data collected from participants indicated deep levels of meaning-making and application of course content to personal approaches to training and teaching. This suggests that incorporating a dance wellness curriculum in a university-level dance program builds exercise science, wellness, and instructional literacy, while encouraging students to apply gained knowledge in both personal and professional capacities.

The purpose of this project was to foster non-inhibited movement exploration such as the movement of untrained dancers in a setting of a music festival (specifically in this case the Grateful Dead community), into the more ritual performance-based ideals and perspectives that tend to occur in a dance studio setting.

The purpose of this project was to foster non-inhibited movement exploration such as the movement of untrained dancers in a setting of a music festival (specifically in this case the Grateful Dead community), into the more ritual performance-based ideals and perspectives that tend to occur in a dance studio setting. The external visual perceptions of what an ideal dancer ‘should look like’ lends itself to unrealistic expectations and unattainable goals as an artist. Body image and the lack of individualized self-expression is a problem in studio settings and the goal of this research was to use the perspective of untrained and trained dancers to dig deep into movement qualities that are not contrived or performed from ritual or preconceived notions of movement that tend to occur in trained dancers. Through exploratory improvisational somatic experiences helping the dancer access a more embodied and authentic self, the choreography was shaped through delving into the dancers lived experiences. This study culminated in a performance dance project that was filmed at Arcosanti, an experimental Artist community in Northern Arizona that integrates the design of architecture with a respect to the ecology. The goal is to limit the environmental footprint that is left by the community.

Aging is a universal process that every being encounters on their journey of life. The effect of dance as a form of improvement of physical and well-being on the aging body brings upon the question of the impact of somatic-based movement, specifically gestural movement on the perceptions of aging within older and younger adults through a bi-cultural lens of the United States and India. This was investigated using a series of creative partnership workshops that included listening, drawing, and culminating movement activities, followed by a group discussion about the creative process. There were four different participant groups: a group of college students taking an Aging in American Culture collegiate class, a Somatic Practices collegiate dance class, a group of older adults at the Tempe Multigenerational Center, and a group of older adults in Bangalore, India. Inter-generational and cross-cultural observations were discussed, and it was seen that the workshops were able to foster feelings of community and camaraderie among participants depending on the group’s relationship to dance-making. From the research, a dance performance was developed and performed specifically with women of color in ASU’s Dance program with the choreographic process discussed in detail, along with key takeaways about facilitating a multi-dimensional experience for the dancers and choreographer. Future directions for the work include working with intergenerational populations and researching community effects on gendered aging experiences across cultures in the dance world.
