Endoscopic sinus surgery training courses: Benefit and problems – a multicenter evaluation
No full textIntroduction: Dissection courses are important for trainees and surgeons in
mastering the skills required to perform endoscopic sinus surgery (ESS) which is
a common surgery in otorhinolaryngology.
Aim: To evaluate the benefits of ESS training courses and ways to improve
training.
Material and methods: In a prospective study using a structured questionnaire, participants of ESS courses in the United Kingdom, Malaysia, India and
Thailand were asked on their experiences in these courses and suggestions on
improving them.
Results and discussion: The majority of the participants have experiences
in performing ESS prior to joining the course. Infundibulotomy was considered
the easiest dissection step in ESS while frontal sinus surgery was considered the
most challenging by the majority of the participants. The motivation for most
of the participants in joining the course is to improve their skills with almost
all stating that their expectations of the course have been fulfilled with improvement of their surgical techniques, anatomical skills and on patient’s safety. Almost all the participants were satisfied with the course and would recommend
attending it.
Conclusions: ESS dissection courses are an integral part in the learning process of trainees in becoming a competent surgeon and for surgeons to improve their
techniques. Continuous improvement should be made to ensure that the participants will benefit from attending the cours

On the Structures of the Hard Palate of Felis tigris
No full text【Abstract】On December 13,1925, news was received of the appearance of
a tiger in the hills of Nan Pu-toa, in Amoy. It was supposed to
have come from the mountnins of Nan Tai Wu, about five miles
from the Amoy Island across the bay, reaching the latter place
by swimming over. Three days later it was shot by police and
brought to the court for exhibition. President Lim Boon Keng, of
the University of Amoy, secured the skeleton for the University
Museum. I had the pleasure of making some observations on
some of the soft structures of the hard palate left with the skull

Mitigation Of Syn-Flooding Attack Using High Speed Programmable Network Processor
No full textDenial of service (DoS) attacks tie up resources of a remote host or network, thereby denying or degrading service to legitimate users. This thesis brings closer two emerging areas of networking, network processor and firewall system. We propose an innovative and practical SYN-flooding defense system built on network processor. An embedded architecture, called synmon (SYN-flooding monitoring) is proposed. Our solution is an end-point-based autonomous system which is deployable at both source and victim network's border routers
HVAC-Aware Occupancy Scheduling (Extended Abstract)
No full textMy research focuses on developing innovative ways to control Heating, Ventilation, and Air Conditioning (HVAC) and schedule occupancy flows in smart buildings to reduce our ecological footprint (and energy bills). We look at the potential for integrating building operations with room booking and meeting scheduling. Specifically, we improve on the effectiveness of energy-aware room-booking and occupancy scheduling approaches, by allowing the scheduling decisions to rely on an explicit model of the building's occupancy-based HVAC control. From computational standpoint, this is a challenging topic as HVAC models are inherently non-linear non-convex, and occupancy scheduling models additionally introduce discrete variables capturing the time slot and location at which each activity is scheduled. The mechanism needs to tradeoff minimizing energy cost against addressing occupancy thermal comfort and control feasibility in a highly dynamic and uncertain system
Fabrication of 3D printing filament utilising recycled PET (rPET) and rPET - PETG blends from marine sources
No full textPlastic, due to its unique advantages compared to other materials, has brought about varied uses across a plethora of industries globally. However, as waste disposal of rubbish (and plastic) is not properly regulated in numerous countries, many of which end up in sewers and rivers across the globe. As the water bodies are connected, the waste gets carried downstream and they eventually end up in the seas as marine waste. Several of the major polluters hail from across Asia, where due to their geographical location, their waste discharge comes close to the Pacific Ocean. These interactions of ocean currents carry waste which eventually forms the Great Pacific Garbage Patch, which is still increasing by size yearly.
Plastic and its derivatives virgin polymers) are important materials for 3D printing process. In recent years, 3D printing has gained immense popularity due to widespread technology advancement which allows 3D printing to be more accessible due to a lowering of price of 3D machineries. With more consumers recognising the benefits and ease of convenience that 3D printing brings, the increase in popularity in 3D printing has led to an increase in demand for raw material (polymer filament) required during the process.
This paper explores the possibility of creating 3D printing filament from using recycling marine waste plastic collected from Singapore’s shorelines, effectively giving the plastic a second life.Bachelor of Engineering (Materials Engineering

No full textFeasibility of pre-treating wastewater/water to prevent /minimize reverse osmosis(RO) membrane biofouling using combined UV/Ozone processes
No full textAs biofouling is a prevalent problem in Reverse Osmosis membranes, the use of advance oxidation processes (AOP) to solve this issue has been researched on by many. This study focuses on the effect of combine UV/Ozone advance oxidation process in inactivating a model bacteria. Pseudomonas aeruginosa (PA01) was chosen as it is one of the common opportunistic bacteria that has been detected in biofilms in RO membranes. A stable consistent PA01 culture was obtained and exposed to UV/Ozone. Ozone strength was varied between 100-400mg/h while keeping the UV strength constant at 2.5W. Based on the results, the inactivation effiency was able to reach 100% within 1 minute for all experiments carried out. The kinetic graph was plotted and has shown that the rate constant increases with increase ozone strength. Results has concluded that the use of 400mg/h ozone strength combined with 2.5W UV-C lamp has the best result for killing PA01 of various concentrations within 10 seconds. Energy efficiency was calculated and has shown that 400mg/h ozone strength combined with 2.5W UV-C lamp is the most energy efficient when compared with 400mg/h ozone and 2.5W UV-C lamp individually. This is likely attributed to the synergic effect of the UV/Ozone combined oxidation process, making it a very powerful disinfectant for PA01, thus being the most energy efficient choice. The combine UV/Ozone process appears to be a very promising treatment to prevent membrane biofouling, thus it is strongly recommended for potential future research to use as a pre-treatment disinfectant.

5G Multi-Tier Handover with Multi-Access Edge Computing: A Deep Learning Approach
No full textThe research presented in this thesis discusses the potential enhancement of 5G multi-tier handover. This proposal will utilise two of 5G’s enabling technologies, multi-access edge computing (MEC) and machine learning (ML). MEC and ML techniques are believed to be the primary enablers for enhanced mobile broadband (eMBB) and ultra-reliable and low latency communication (URLLC). The subset of ML that was chosen for this research is deep learning (DL), as it is great at learning long-term dependencies. A variant of artificial neural networks called a long short-term memory (LSTM) network is used in conjunction with a lookup table (LUT), as part of the proposed solution. Subsequently, edge computing virtualisation methods are utilised to reduce handover latency and increase overall throughput of the network. In addition to the proposed, this thesis analyses the validity of various other potential solutions such as multi-connectivity, cloud centralised radio access networks (Cloud C-RAN) and artificial intelligence (AI).
To implement the proposed algorithm, a software simulation of a multi-tier 5G heterogeneous network is developed, based on the 3rd generation partnership project (3GPP) standards for: channel models, schedulers, and handovers. This simulator provided the tools for the author to analyse and evaluate the feasibility of the proposed solution.
The results gained from the research was promising. It showed a 40−60% improvement in overall throughput under high user densities. Although the proposed scheme may increase the number of handovers, it is effective in reducing the handover failure (HOF) and Ping-Ping rates in higher user density scenarios by 30%, and 86% respectively, compared to current state-of-the-art. In conclusion, a detailed analysis was undertaken, and the aims of the research were satisfied
