Luk-khrueng Between Worlds
No full textLuk-khrueng Between Worlds is a memoir about growing up between cultures, that of my white New Zealand father, and my mother’s Thai culture. My childhood years in Thailand during the 1960s and early 1970s was marked by the war in Vietnam, and the influx of American military personnel who brought significant cultural change to Thailand. My teenage years straddle Thailand and New Zealand where I completed high school and began my working life as a School Dental Nurse. I came to Australia in 1979 as a 20-year-old, seeking to follow my father’s footsteps into the Australian bush. In the Northern Territory I married a man I met while working as a governess on a remote cattle station. Much of my memoir is set in the Australian landscape, from the cattle stations in the country’s north, the vast sheep runs of Queensland and through to the cool mountain environments of the Upper Murray region of southern New South Wales. My love of the land began in the rice paddies of northern Thailand. By intertwining narratives of those childhood years with my experiences in the Australian landscape, I explore the major themes of my life; childhood and intergenerational trauma, family violence, grief, shame, identity and belonging, as well as gender, sexuality and interracial relationships. As an eco-memoir partially set in Australia’s Northern Territory, in my exegesis I examine other memoirs written by white women in the Top End in order to frame my own experiences as an outsider, a migrant and a witness, as well as a beneficiary of settler heritage in a colonised country. This exegesis, written after the devastating bushfires of 2019 that threatened our mountain home, and through the fear, confusion and restrictions of COVID-19, also deals with grief and the sudden loss of my mother in 2021. It is an exegesis reflecting on language and story, and their authority to effect identity, community, citizenship and social and political change
Adaptive simulated annealing for optimization in signal processing applications
No full textMany signal processing applications pose optimization problems with multimodal and nonsmooth cost functions. Gradient methods are ineffective in these situations. The adaptive simulated annealing (ASA) offers a viable optimization tool for tackling these difficult nonlinear optimization problems. Three applications, maximum likelihood (ML) joint channel and data estimation, infinite-impulse-response (IIR) filter design and evaluation of minimum symbol-error-rate (MSER) decision feedback equalizer (DFE), are used to demonstrate the effectiveness of the ASA
Digital IIR filter design using particle swarm optimisation
No full textAdaptive infinite-impulse-response (IIR) filtering provides a powerful approach for solving a variety of practical signal processing problems. Because the error surface of IIR filters is typically multimodal, global optimisation techniques are generally required in order to avoid local minima. This contribution applies the particle swarm optimisation (PSO) to digital IIR filter design in a realistic time domain setting where the desired filter output is corrupted by noise. PSO as global optimisation techniques offers advantages of simplicity in implementation, ability to quickly converge to a reasonably good solution and robustness against local minima. Our simulation study involving system identification application confirms that the proposed approach is accurate and has a fast convergence rate and the results obtained demonstrate that the PSO offers a viable tool to design digital IIR filters. We also apply the quantum-behaved particle swarm optimisation (QPSO) algorithm to the same digital IIR filter design and our results do not show any performance advantage of the QPSO algorithm over the PSO, although the former does have fewer algorithmic parameters that require tuning

Non-parametric linear time-invariant system identification by discrete wavelet transforms
No full textWe describe the use of the discrete wavelet transform (DWT) for non-parametric linear time-invariant system identification. Identification is achieved by using a test excitation to the system under test (SUT) that also acts as the analyzing function for the DWT of the SUT's output, so as to recover the impulse response. The method uses as excitation any signal that gives an orthogonal inner product in the DWT at some step size (that cannot be 1). We favor wavelet scaling coefficients as excitations, with a step size of 2. However, the system impulse or frequency response can then only be estimated at half the available number of points of the sampled output sequence, introducing a multirate problem that means we have to 'oversample' the SUT output. The method has several advantages over existing techniques, e.g., it uses a simple, easy to generate excitation, and avoids the singularity problems and the (unbounded) accumulation of round-off errors that can occur with standard techniques. In extensive simulations, identification of a variety of finite and infinite impulse response systems is shown to be considerably better than with conventional system identification methods.Department of Computin
Delicious Luk-Luk / Shieralyn Mosiun... [et al.]
No full textDelicious Luk Luk is a food truck service that sells variety of foods with a
cheap price to the consumers. Our food truck will be in two different places at
noon and night, since we are targeting the low income people and University
students from UiTM Kota Kinabalu, Politeknik Sepanggar, lnstitut Kemahiran
Mara Sepanggar and other institutes nearby Sepanggar, we will start our
business at Indah Permai Sepanggar because it is the most strategic location
and it is easier for our customers to find our food truck there. Our business
will move to Tanjung Aru beach at night. We decided to open our business
there because Tanjung Aru beach is one of the main attractions in Kota
Kinabalu and lots of people will visit Tanjung Aru beach every day and we
saw an opportunity to attract more customers there.
The main products that we will produce are economy rice and Luk Luk. We
have chosen to produce economy rice because "food truck service" has been
a very popular business in Kota Kinabalu over the year and we wanted to
make something unique by producing economy rice as our main product
since none of the other food truck services served as one of their menus.
Other than that, we also offer delivery service to our customers without any
charge. The delivery service will be done at any time in a day since we have
our own transportation other than the food truck, this will make it easier for us
to make our delivery service at any time. That is what makes our business
unique because one of our missions is to satisfy our customers' wants and
needs
