### Questions:

1. George Watsky’s spoken word poem “Tiny Glowing Screens Pt. 2” deals with a significance of concealed feelings and the results of living in a westernized society that often asks us to conceal and suppress feelings for the benefit of everyone else.

Talk about how Watsky engages with this idea of concealed or even suppressed feelings and how he reacts baring his interior feelings to the rest of the world. Be sure to use specific examples from the text to support your thinking. Lyrics can be found at Genius.com.

2. In Watsky’s essay “Fa Kieu,” we are introduced to three different schools that all present different challenges to a young George in search of identity: Buena Vista, Alamo, and Estacada.

Take one of these schools and explain briefly what influence they left on Watsky and what coping mechanisms he used to handle his time there.

3. In Watsky’s essay “What Year Is It?” we are introduced to the disability that Watsky has lived with for most of his life: epilepsy. For Watsky, epilepsy is not an entirely debilitating condition, but one that has influenced and affected his life in significant ways.

Explain how Watsky came to terms with his disability and why his writing about his condition might be valuable to readers also experiencing their own issues with disability(s).

### ELEC 4123 Electrical Design Proficiency : Identify Mathematical Model

System Identification
In this task, you are required to understand the dynamic behaviour of the DC MG system and identify mathematical model for it through analysing the actual recoded data and the equivalent Simulink model of the
device as shown in Figure 1. These data are recorded via an Oscilloscope (short-period state-state response
at a high resolution) and an Arduino (long-period dynamic and state-state response).

Four different sets of measured data are available for you to analyse the actual behaviour of the system. The
DC MG was hooked up to a motor driver (TB67H420FTG H-Bridge). Oscilloscope data were recorded for a
period of 50ms at a high resolution during steady-state response (50,000 samples) for duty cycles of 20% to
80%. This provides a detailed behaviour of the system including high frequency noise, low frequency vibration,
input current ripple, and issues with Arduino PWM generator. In reality, we would use a microcontroller to
implement a control system for real time control, so the measurements have to be recorded and processed
by, for example, an Arduino. Therefore, I have recorded the output voltage across a 10Ω high-power load
resistor (which you can use to estimate the output current) as well as reading the PWM signal back into
Arduino (which is useless due to a massive aliasing).
All the tests were carried out with 4 different PWM frequencies, 490Hz, 976.5Hz, 1.96kHz and 7.81kHz (some
other frequencies are also available, but I did not use them like 3.92kHz, 31.37kHz and 62.5kHz). The Arduino
real time operation was compiled in Simulink with a baud rate of 57600. As a result of many overhead codes
used by Simulink, a low-resolution sampling frequency of 100Hz had to be chosen to have a consistent
sampling rate in the recorded data via Arduino. This gives you a practical insight into the impact of heavy
aliasing in the measurements and the impact of quantization and down-sampling noise introduced into the
data, which you need to consider when using these data for dynamic modelling.
Another practical aspect of this task is to investigate how the PWM control affects the operation of the DC
motor. It is known that a DC motor can be more efficiently controlled through changing the duty cycle of the
PWM (compared to using a linear voltage regulator) because the DC motor responds to the average value of
the PWM signal (think why that is the case!). However, this introduces new issues for the motor such creating
input current ripple and triggering some nonlinearity (think about what the impacts of the large current ripple
are or what happens to the H-Bridge switching MOSFETs if the frequency of PWM is too high). There is a
technique called motor current smoothing where a motor choke is added in series with the positive terminal
of the motor to reduce the ripples. But you have to consider a trade-off between the size of the current
smoothing inductance and the PWM frequency. You need to think about and make a choice on their values
for this task (there are other techniques like LC filtering which you might want to look into as well).
The Simulink model of the system is shown in Figure 2. You will be provided with nominal estimated
parameters of an actual DC MG to derive two transfer functions, one with the load resistance voltage (

### 301062 Environmental Building Design

ASSIGNMENT OVERVIEW The Architectural drawings given feature a typical Medium Density Residential Development in a western suburban region. The current design aims to maximize development potential (total of eight mixed single and two storey units) by consolidating two typical suburban lots into one with a central access driveway. The development needs improvement in relation to Environmental Building Design (EBD) principles. TASK You will review this design with an incorporation of Environmental Building Design (EBD) principles. You will develop new individual drawings where you will reconfigure the overall site layout to produce an improved environmental design for the site, as well as detail one specific unit. You need to incorporate a range of EBD elements into the fabric and layout of the unit (appropriate passive design methods, energy and water efficient measures, renewable technologies, waste management, etc). The incorporation of EBD principles must be performed to the site (whole development) as well as to the individual unit (which is a representation of all the EBD principles that were incorporated in all different units in your development
