Negative Gilbert damping in cavity optomagnonics
No full textExceptional point (EP) associated with the parity-time (PT) symmetry breaking is receiving considerable recent attention by the broad physics community. By introducing balanced gain and loss, it has been realized in photonic, acoustic, and electronic structures. However, the observation of magnonic EP remains elusive. The major challenge is to experimentally generate the negative Gilbert damping, which was thought to be highly unlikely but is demanded by the PT symmetry. In this work, we study the magneto-optical interaction of circularly-polarized lasers with a submicron magnet placed in an optical cavity. We show that the off-resonant coupling between the driving laser and cavity photon in the far-blue detuning can induce the magnetic gain (or negative damping) exactly of the Gilbert type. A hyperbolic-tangent function ansatz is found to well describe the time-resolved spin switching as the intrinsic magnetization dissipation is overcome. When the optically pumped magnet interacts with a purely lossy one, we observe a phase transition from the imbalanced to passive PT symmetries by varying the detuning coeffcient. Our findings provide a feasible way to manipulate the sign of the magnetic damping parameter and to realize the EP in cavity optomagnonics
Direct conversion RF front-end with a low-power consumption technique for 2.4 GHz ISM band
No full textThe implementation and performance measurements of RF front-end are presented. The low-power RF front-end designed in TSMC 0.18 mm process for 2.4 GHz ISM band direct conversion is presented. The proposed RF front-end is comprised of the folded mixer, fully differential low-noise amplifier (LNA) and interstage matching network. Gilbert-cell mixers using the folded technique and current reused LNA are designed for low power consumption. The folded mixers are implemented by using PMOS devices in the switching stage of mixers with a resonating inductor for low flicker noise. The proposed RF front-end consumes 7.2 mW from the 1.2 V supply and a conversion gain of 23 dB is achieved. The third-order intercept point (IIP3) is -10.5 dBm, and the proposed RF front-end has good linearity. By using PMOS devices and the folded technique, low flicker noise of 10 dB at 10 kHz is achieved, and thus the proposed RF front-end can be used in the direct conversion receiver for narrow bandwidth
Ouch That Hurt! A Visual EP and Documentary
No full textThis culminating experience project consisted of a visual and collaborative Extended Play (referred to as “EP” henceforth) and a documentary of the process of creating a visual EP in its entirety. The most important part of the author’s culminating experience was a finished EP of three original songs. The author created visuals for each song, using a variety of different sources learned during her time at Berklee. The EP featured all original music written by the author and was a collaboration between instrumentalists, recording engineers, mixing and mastering engineers from Berklee. Additionally, each song featured a different analog or digital emulation synthesizer in order to expand the author\u27s knowledge of music technology and of music history in the synth pop genre. The author chose to do an EP for her culminating experience project in order to expand her personal artistry, continue working on her songwriting, production and engineering, learn about new synthesizers, and to capture the entire process in an educational documentary in order to show how an EP is created from start to finish.https://remix.berklee.edu/graduate-studies-production-technology/1270/thumbnail.jp

Inter rater reliability of recovery capital: Assessment of a clinician rated measure
No full textThis study investigated the inter rater reliability for the Clinician Recovery Capital Measure as a tool to assess recovery capital for clients with alcohol and other drug problems. The sample consisted of 15 women (M = 40.07 years, SD = 10.79 years) and 6 men (M = 47.83 years, SD = 13.57 years), who had at least a three year degree or equivalent in a relevant field plus professional/practical experience with mental health clients. Assessment of inter rater reliability required participants to code standardised case notes using the Clinician Recovery Capital Measure. Data were analysed for total recovery capital as well as the subcategories of social, human, cultural and physical capital. Use of the Intra Class Correlation Coefficient (ICC) demonstrated excellent levels of inter rater reliability for total recovery capital ICC = 0.909, social capital ICC = 0.884, human capital ICC = 0.775, cultural capital ICC = 0.857, and physical capital ICC = 0.975. These ICC results demonstrate that the Clinician Recovery Capital Measure can be reliably coded by a range of mental health practioners in an Australian clinical context. This study is an important step in the development of the clinician recovery capital measure and the process of operationalising recovery.

EP - Kyan Palmer
No full textabstract: "EP \u2014 Kyan Palmer" is a compilation of three songs, "Hit List," "Queen Cobra," and "Burn Mona Lisa" all written and recorded by Barrett student, Kyan Palmer. The project explores the process involved in creating recorded music and exposes the vulnerability and self-reflection in writing a song. The following depicts the thought process that came about in the creation of each song from the lyrics, to the vocals, to the production. This paper depicts a journal-like writing style outlining the various events that took place while creating EP \u2014 Kyan Palmer. The bulk of this Thesis/Creative Project was the written, produced, and recorded music attached in the appendix. With that said, the following document is intended to be reflective rather than scholarly and acts as an accompaniment to the audio recordings and video entries
Hammock, An EP and Visuals about Ego and Success
No full textThis project seeks to produce a musical universe in the form of an Extended Play (EP) with seven songs and accompanying visuals. The EP is a concept album that is centered on themes of ego and success. This album blends rock, electronic, hip-hop, and storytelling. This project was recorded and mixed in the Berklee Valencia studios. First, a template was made for each part of the story and visual themes, and then the songs were recorded instrument by instrument. All the sounds, visuals, samples and music are original creations by the author of the project Michael Dodson. The author learned how to design sounds and visuals to represent thematic elements in the music. In the future, he will create a live show based around the EP. The show will feature live composing and live visuals.https://remix.berklee.edu/graduate-studies-production-technology/1294/thumbnail.jp
Please Rewind: An Instrumental EP
No full textThis project is an instrumental EP, consisting of five tracks which the author wrote, produced and mixed. The goal for the project was to create a complete project that would serve to showcase the author’s abilities as a musician, sound designer and engineer, in order to assist in the search for career opportunities after graduation. The project combined modern Hip Hop influences, with the author’s love for 1980’s era film soundtracks and their synth heavy scores, into a blend that highlights the music the author is passionate about, and how he can contribute to its creation.https://remix.berklee.edu/graduate-studies-production-technology/1176/thumbnail.jp
