A Method For The Measurement Of The Latency Tolerance Range Of Western Musicians, Jorge Medina Victoria
A Method For The Measurement Of The Latency Tolerance Range Of Western Musicians, Jorge Medina Victoria
PhDs
This thesis presents a new systematic method to measure the ability of western musicians to cope with latency. The core of the method is a listening test and the development of a measure. The viability of the method is statistically tested with an empirical observation of 31 test subjects performing on 17 different musical instruments.
The primary goal of the investigation is the development of a systematic, reliable and replicable method that can be applied to different western music instruments, in order to provide data for analysis on latency issues while performing music in non-collaborative performances. In addition, a measure …

Fall Detection Using Channel State Information From Wifi Devices, D.M Sameera Palipana
PhDs
Falls among the independently living elderly population are a major public health worry, leading to injuries, loss of confidence to live independently and even to death. Each year, one in three people aged 65 and older falls and one in five of them suffers fatal or non fatal injuries. Therefore, detecting a fall early and alerting caregivers can potentially save lives and increase the standard of living. Existing solutions, e.g. push-button, wearables, cameras, radar, pressure and vibration sensors, have limited public adoption either due to the requirement for wearing the device at all times or installing specialized and expensive infrastructure. …
Wireless Sensors For Health Monitoring Of Marine Structures And Machinery, Francisco David Rojas Calvente
Wireless Sensors For Health Monitoring Of Marine Structures And Machinery, Francisco David Rojas Calvente
PhDs
Remote structural and machinery health monitoring (SMHM) of marine structures such as ships, oil and gas rigs, freight container terminals, and marine energy platforms can ensure their reliability. However, the wired sensors currently used in these applications are difficult and expensive to install and maintain. Wireless Sensor Networks (WSN) can potentially replace them but there are significant capability gaps that currently prevent their long-term deployment in the harsh marine environment and the structurally-complex, compartmentalised, all-metal scenarios with high volume occupancy of piping, ducting and operational machinery represented by marine structures. These gaps are in sensing, processing and communication hardware and …
Efficient Control Message Dissemination In Dense Wireless Lighting Networks, Conrad Dandelski
Efficient Control Message Dissemination In Dense Wireless Lighting Networks, Conrad Dandelski
PhDs
Modern lighting systems using LED light sources lead to dense lighting installations. The control of such systems using wireless Machine-to-Machine (M2M) where standard LED light sources are replaced by wirelessly controllable LED light sources create new problems which are investigated in this thesis. Current approaches for control message transmission is such networks are based on broadcasting messages among luminaires. However, adequate communication performance - in particular, sufficiently low latency and synchronicity - is difficult to ensure in such networks, in particular, if the network is part of a wireless building management system and carries not only low-latency broadcast messages but …
