UNLABELLED Uniformity testing is performed daily to ensure adequate camera performance before clinical use. The aim of this study is to assess the reliability of Beth Israel Deaconess Medical Center's locally built, centralized, Web-based uniformity analysis system by examining the differences between manufacturer and Web-based National Electrical Manufacturers Association integral uniformity c...

In this thesis, we step inside an unexplored region of Wireless Sensor Networks (WSNs) research. Nowadays, almost all WSNs research relies upon a hidden uniformity assumption. This assumption involves deployment, distribution and radio transmissions. Unfortunately, the real world is not uniform. In the thesis, we break the uniformity assumption and study the non-uniformity influence in WSNs. In...

Plot size has an important impact on variation among plots in agronomic field trials, but is rarely considered during the design process. Uniformity trials can inform a researcher about underlying variance, are seldom used due to their laborious nature. The objective of this research was describe maize varying and develop tool optimize field-trial using uniformity-trial statistics. Six uniformi...

Application requirements for avionics are often very strict. For example, the heat sinks of avionics need very good temperature uniformity, but the flow rate of coolant is very restricted. In addition, the use of micro-channels is not recommended due to the potential clogging issue. Considering these design requirements, we will discuss a multiple-objective optimal design method to obtain a goo...

We report the application of the technique of infrared transmission to measure the temperature of silicon wafers during the growth of silicon-germanium alloy heteroepitaxial layers in a rapid thermal processing system. The silicon-germanium alloy layers have negligible absorption at 1.3 and 1.55 pm over wide ranges of thickness, composition, and strain condition. The substantial improvement of ...

In a nulling interferometer, the requirements on uniformity of phase, amplitude, and state of polarisation among the interferometer arms are stringent and hardly to be met in practice. The application of modal filters makes deep nulling possible as such filters may reduce the mismatch of interfering fields. We review the principle of modal filtering and discuss the achievable filter bandwidth a...

Preparation of dense alumina (Al₂O₃) thin film through atomic layer deposition (ALD) provides a pathway to achieve the encapsulation of organic light emitting devices (OLED). Unlike traditional ALD which is usually executed at higher reaction n temperatures that may affect the performance of OLED, this application discusses the development on preparation of ALD thin film at a low temperature. O...
