Solubility parameters of carbon quantum dots (CQDs) are important physical properties to deploy CQDs in various applications such as organic light emitting diodes (OLEDs), light-converting materials in LEDs, and photoluminescent sensors for metal ion detection. Because of the low toxicity and tunable emission most CQDs have been designed to be water-soluble and biocompatible; oilsoluble CQDs that are essential for OLEDs are not yet explored.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

This study develops an online unmanned UAV path-planning strategy for autonomous search and localisation of RF emitter. The UAV is equipped with Receiver Signal Strength (RSS) sensors to localise stationary radio frequency (RF) emitter. A high-fidelity non-linear measurement model of RF propagation in an urban environment is adopted for this purpose. The measurement model of the likelihood function is considered a Gaussian mixture.

A gene encoding thermostable Lon protease fromBrevi-bacillus thermoruberWR-249 was cloned and characterized. TheBr. thermoruberLon gene (Bt-lon) encodes an 88 kDa protein characterized by an N-terminal domain, a central ATPase domain which includes an SSD (sensor- and sub-strate-discrimination) domain, and a C-terminal protease domain. The Bt-lon is a heat-inducible gene and may be controlled under a putativeBacillus subtilisr A -dependent promoter, but in theabsenceofCIRCE(controlling inverted repeat of chaperone expression)....

Histidine-containing protein (HPr) is a central metabolic sensor in low-GC Gram-positive bacteria and plays a dual role in sugar uptake by the phos-phoenolpyruvate–sugar phosphotransferase system and in transcriptional control during carbon catabolite repression. The latter process is mediated by interaction between HPr and the carbon catabolite repression master transcription regulator, carbon catabolite protein A (CcpA), a member of the LacI-GalR family of DNA-binding proteins.

In proteobacteria capable of H2oxidation under (micro)aerobic conditions, hydrogenase gene expression is often controlled in response to the availab-ility of H2. The H2 -sensing signal transduction pathway consists of a het-erodimeric regulatory [NiFe]-hydrogenase (RH), a histidine protein kinase and a response regulator.

LINEAR SIGNAL CONDITIONING TO SIX-SIGMA CONFIDENCE INTRODUCTION Economic considerations are imposing increased accountability on the design of analog I/O systems to provide performance at the required accuracy for computerintegrated measurement and control instrumentation without the costs of overdesign. Within that context, this chapter provides the development of signal acquisition and conditioning circuits, and derives a unified method for representing and upgrading the quality of instrumentation signals between sensors and data-conversion systems....
