Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab, we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe, 2) measure the length of a closed-pipe resonator, and 3) analyze the data to determine the speed of sound. Procedure: 1. Fill the graduated cylinder nearly to the top with water, with a tall glass tube open at both ends (the water level with act as the closed end). 2. Determine the

How can you describe the Heathers? According to Veronica Sawyer they are simply popular, beautiful, mythic bitches. But do they deserve to die? Heathers took me on an exciting journey with the seniors of Sherwood Ohio that challenge the ideas of homosexuality, promiscuousness, and most obviously suicide. I was lucky enough to experience this twice throughout the run of the show and it was the second time watching the show that I fell in love with the characters and saw the actor’s desire to share

2.8. Optical ring resonator based sensor performance metrics To compare different kinds of optical RR based sensors, it is necessary to define some performance metrics. The suitability of optical sensors for a particular application will depend on their performance across number of sensor requirements. Some metrics such as sensitivity, and sensor cost, can be defined numerically (either by means of experimental or theoretical calculations). Other metrics such as portability is more subjective or

A cacophony of sounds twisted through the air as the house lights dimmed and the stage lights rose on a sun reddened sky. The stage began to fill as voice after voice joined the chorus. Elaborately costumed elephants and antelope paraded through the aisles. It was loud, organized chaos. It was my first time at the theatre, and as a mere eight year old, it scared me - at first. But as I kept watching, everything started to fall into place. I listened to how the singers’ individual voices fit into

breath, but it also came using breathe to stay present in the room. The use of breath also allowed me to go into my body and release the build-up of emotions. As a result of these experiences, my voice was able to drop more consistently to my lower resonator rather than my typical chest voice. The new drop in my voice had its own challenges as well. One, of course, was to avoid reverting into old habits. When it comes to voice work, effort should be applied every day. Just because I was breathing deep

8 We systematically demonstrate that one-dimensional phononic crystal (1-D PnC) tethers can signif- 9 icantly reduce tether loss in micromechanical resonators to a point where the total energy loss is 10 dominated by intrinsic mechanisms, particularly phonon damping. Multiple silicon resonators are 11 designed, fabricated, and tested to provide comparisons in terms of the number of periods in the 12 PnC and the resonance frequency, as well as a comparison with conventional straight-beam tethers.

The term dielectric resonator (DR) first appeared by Ritchmyer [19], when he showed that unmetallized dielectric objects in the form of toroids could function as microwave resonators. However, his theoretical investigations failed to generate significant interest and practically nothing happened in this area for over 25 years. In the early 1960s, researchers from Columbia University, Okaya and Barash [34-35] reported the first ever DR in the form of a single crystal TiO2. In the mid-1960s, Cohn [36]

tuning fork resonators via a force amplifier like a mechanical lever with a special configuration. This schematic of this structure is depicted in Fig. 1. Each of the DETF resonators is actuated to their resonance electrostatically and they will be sustained in their resonance by a feedback loop[17]. When an external acceleration is applied to the structure in proper direction, the proof mass will deflect and as a result of this movement an axial force will transfer to the DETF resonators. This axial

During the last two decades, organic semiconductor lasers (OSLs) have attracted much attention due to their advantageous properties such as wavelength tunability in the visible range,1 low cost, flexibility,2 and large area fabrication.3 These properties make them good candidates for a range of applications including sensing,4 spectroscopy,5 and optical communication.6 However, only optically pumped organic lasers have been realized so far, and the demonstration of an electrically driven organic

According to the acoustic theory of speech production, what we know to be speech output results from a source of sound energy (e.g. the larynx) modulated by a transfer (filter) function which is determined by the shape of the resonator (vocal tract). This model, often referred to as the "source-filter theory of speech production," originates from the works of Gunner Fant (1960, 1980) and Stevens and House (1955, 1961) (Haskins Laboratory, Yale University 2008). Source filter theory puts forth two
