Opening position of a Research Assistant for a Study of Photovoltaic (PV) Systems

by

We are looking for a full time (5 days a week, 8 hours) Research Assistant for 24 months appointment to commence in January 2017.
 
Project: The research tasks explore innovative ideas investigating the impacts of photovoltaic (PV) systems selection and their impact on localised power generation for net-zero energy building movement. Modifications to the PV systems to enhance their power generation efficiency will be examined to satisfy the increasing demand and reduce maintenance of the systems under tropical context. This research will run in parallel with other two researches related to the Tropical Technology (T2) Lab and the energy efficient PV systems in tropical environment. Therefore, a regular collaboration among two or three RAs is also expected.
 
Domain: Solar energy, Photovoltaic, BIPV
 
The appointed RA will be involved in the following tasks:

  • Assist and take care of all the tasks related to publications related to the domain.
  • Participate in research and writing of articles
  • Assist in development, design, and setup of the photovoltaic research facilities
  • Analysis and collection of data, and graphical representation of information using suitable tools (such as Autocad, MATLAB, PVsyst, etc.)

Job Requirements:

  • Master’s Degree in Architecture or Bachelor’s (preferably Master’s) Degree of Electrical and Electronic Engineering or other relevant engineering
  • Knowledge in the photovoltaic systems and design
  • Experience in research work and writing
  • Skilled in graphic design and representation
  • Capacity to work independently
  • Management skills

There is a new publication regarding the use of acoustic vector-sensor (a.k.a. the vector hydrophone) near a reflecting boundary.  The article is published in the Journal of the Acoustical Society of America.  Please visit this link.

Classroom Acoustics Session at ASA meeting in Salt Lake City

by

Dr Siu-Kit Lau and Prof Shiu-Keung Tang have chaired a session of Classroom Acoustics at the 171st Meeting of Acoustical Society of America in Salt Lake City on 23-27 May 2016.  During the meeting, Prof Tang and Dr Lau presented a paper entitled “Cantonese speech intelligibility tests in two Hong Kong primary school classrooms”.  Abstract of the presentation can be found at this link. A preliminary observation is that there is higher probability for the pupils to give wrong answers when the sound of a character lasts for relatively long duration, especially when there are abrupt temporal changes in the time-frequency spectra. Correct answers are usually given when the corresponding time-frequency spectral energy is more concentrated within a short duration.

An impedance-mobility model of acoustic metamaterials

by

A fast prediction method for the performance of stacked membrane-type metamaterials has been developed using An impedance-mobility model.  Matthew Blevins of the University of Nebraska-Lincoln introduced the method and a Matlab platform regarding this approach at the Spring 2015 meeting of Acoustical Society of America.  The work is collaborated and supervised by Dr. Siu-Kit Lau and Dr. Lily Wang.  Metamaterials are man-made materials to have properties that have not yet been found in nature. Membrane-type acoustic metamaterials have been proven to exhibit high low-frequency transmission loss despite their small thickness and light weight.  The efficient model based on the impedance-mobility can be used to facilitate design and optimization of stacked membrane-type acoustic metamaterials.
