External morphology of the first and second instars of Lecanodiaspis tingtunensis (Coccoidea: Lecanodiaspididae)
The first and second instars of Lecanodiaspis tingtunensis are described and illustrated. First instars are distinguished from other species of Lecanodiaspis by the arrangement of dorsal 8-shaped pores in six complete longitudinal rows and a partial row in the thoracic region and the number of labial, anal plate, and spiracular setae. Second instars are dimorphic with males possessing well developed 5-segmented legs, dorsal tubular ducts, and long hair-like setae on the venter between the antennae and on the abdominal segments. Females have fewer 8-shaped pores in transverse rows on the dorsum, as well as legs reduced to stubs and only one pair of hair-like medial setae on the venter

A new approach to numerical characterisation of wear particle surfaces in three-dimensions for wear study
In the wear and tear process of synovial joints, wear particles generated and released from articular cartilage within the joints have surface topography and mechanical property which can be used to reveal wear conditions. Three-dimensional (3D) particle images acquired using laser scanning confocal microscopy (LSCM) contain appropriate surface information for quantitatively characterizing the surface morphology and changes to seek a further understanding of the wear process and wear features. This paper presents a new attempt on the 3D numerical characterisation of wear particle surfaces using the field and feature parameter sets which are defined in ISO/FDIS 25178-2. Based on the innovative pattern recognition capability, the feature parameters are, for the first time, employed for quantitative analysis of wear debris surface textures. Through performing parameter classification, ANOVA analysis and correlation analysis, typical changing trends of the surface transformation of the wear particles along with the severity of wear conditions and osteoarthritis (OA) have been observed. Moreover, the feature parameters have shown a significant sensitivity with the wear particle surfaces texture evolution under OA development. A correlation analysis of the numerical analysis results of cartilage surface texture variations and that of their wear particles has been conducted in this study. Key surface descriptors have been determined. Further research is needed to verify the above outcomes using clinic samples

Detection and prediction of osteoarthritis in knee and hand joints based on the X-ray image analysis
Current assessment of osteoarthritis (OA) is primary based on visual grading of joint space narrowing and osteophytes present on radiographs. The approach is observer-dependent, not sensitive enough for the detection of the early stages of OA and time consuming. A promising solution is through fractal analysis of trabecular bone (TB) textures on radiographs. The goal is to develop an automated decision support system for the detection and prediction of OA based on TB texture regions selected on knee and hand radiographs. In this review, we describe our progress towards this development which was conducted in five stages, i.e., (i) development of automated methods for the selection of TB texture regions on knee and hand radiographs (ii), development of fractal signature methods for TB texture analysis, (iii) applications of the methods in the analysis of x-ray images of knees and hands, (iv) development of TB texture classification system, and (v) development of ReadMyXray website for knee x-ray analysis. The results achieved so far are encouraging and it is hoped, that once the system is fully developed and evaluated, it will be used to aid medical practitioners in the decision-making, i.e., in designing OA preventative measures, treatments and monitoring the OA progression

Large Scale Speech Synthesis Evaluation
In speech synthesis evaluation, it is critical that we know what exactly affects the
results of the evaluation rather than employing as vague notions as, say, "good quality
speech". As so far we have only been able to rely on people's subjective judgements, a
deep understanding of the mechanisms behind those judgements might lead to, first,
an improvement in the overall quality of synthetic speech that could now address
precisely the points that users find relevant, secondly, to a better subjective evaluation
method design, and third, to designing an objective method of evaluation, that would
offer stable and reliable comparison across and within systems. We base our work on
the data from a large scale speech synthesis evaluation challenge, the Blizzard
Challenge 2007, and we use a Multidimensional Scaling technique to map the
acoustic features that users pay attention to while evaluating synthetic speech onto the
dimensions along which the systems differ. We then present the results of a perceptual
experiment conducted to test the hypothesis. The final parts of the thesis offer a
discussion of the results and suggest some new directions for speech synthesis that
follow from our findings
