'It's not the form; it's the process' a phenomenological study on the use of creative professional development workshops to improve teamwork and communication skills
Venue: Medical Humanities

Past research has demonstrated the positive effects of visual and performing arts on health professionals' observational acuity and associated diagnostic skills, well being and professional identity. However, to date, the use of arts for the development of non technical skills, such as teamwork and communication, has not been studied thoroughly.  In partnership with a community print and media arts organisation, Centre[3] we used a phenomenological approach to explore front line mental health and social service workers' experiences with a creative professional development workshop based on the visual and performing arts. Through preworkshop and postworkshop interviews with participants and postworkshop interviews with their managers, we sought to examine how participants' perceptions of the workshop compared with their preworkshop expectations, specific impacts of the workshop with respect to participants' teamwork and communication skills and changes in their perceptions regarding the use of the arts in professional development.  Our workshops were successful in enhancing teamwork skills among participants and showed promise in the development of communication skills, though observable changes in workplace communication could not be confirmed. The workshop facilitated teamwork and collegiality between colleagues, creating a more enjoyable and accepting work environment. The workshops also helped participants identify the strengths and weaknesses of their communication skills, made them more comfortable with different communication styles and provided them with strategies to enhance their communication skills.  Participation in the arts can be beneficial for the development of interpersonal skills such as teamwork and communication among health professionals.
Regrown Source/Drain Based InGaAs MOSFET with Si3N4 Nitride Spacer

Regrown source/drain technology is highly appreciated in III V MOSFET, to reduce the thermal budget induced by otherwise activation annealing required by ion implantation technology, as well as to reduce the source/drain resistances by highly doping the epitaxial materials. While regrown source/drain technology is facing the problems such as high parasitic source/drain capacitances and high electric field at the gate edge toward the drain side, leading to high drain leakage current. To relieve the leakage current problem as well as to improve the high frequency performances, low k Si3N4 nitride spacer was introduced to the InGaAs MOSFET. Experimental results showed effective performance enhancements by applying nitride spacer in InGaAs MOSFET including drain leakage current and cutoff frequency.
Nominalisation in high scoring primary and secondary school persuasive texts

This paper makes visible particular persuasive language choices made by the highest scoring Tasmanian primary and secondary school students who completed the 2011 NAPLAN writing test. Specifically, it draws on systemic functional linguistics (SFL) to consider how these students used different forms of nominalisation to persuade readers about the 2011 writing prompt: that too much money is being spent on toys and games. The paper explores how the use of nominalisation differed across the primary and secondary school years and draws links to the Australian Curriculum: English which introduces the nominalisation in Year 8. Recommendations are made for primary and secondary school teachers who wish to equip students with the language resources to deal with the demands of NAPLAN testing, but also to write persuasively in more authentic educational and social contexts.
Sb substitution into ZnO nano composite: Ferromagnetic behavior

Properties of particles whose dimensions are of the nanoscale can be quite different from those of bigger dimension particles. We investigate here the effects of doping Sb 5+ ions into ZnO nanorods (NR's) on the formation of magnetic moments. The pure ZnO and Sb doped ZnO NR's were grown by the hydrothermal process. The fabricated nanorods were then studied using X ray diffraction (XRD) ultraviolet visible light spectroscopy (UV vis) Scanning Electron Microscopy (SEM) Photoluminescence (PL) Spectrometer and Vibrating Sample Magnetometer (VSM) spectrometry. Substitution of Sb into the ZnO leads to the formation of a defect (Sb Zn +2V Zn complex state which can capture the oxygen p orbital electrons of the oxygen atoms and form a spin polarized state. The PL was used to monitor the defect formation in the ZnO NR's when the Sb is doped in. As more Sb was doped in, the visible blue portion of the PL spectrum decreased while the visible red portion increased. Magnetization measurements (VSM) showed that the pure ZnO NR's possessed a magnetic moment which initially increased as Sb is doped in but decreased as more Sb was doped in. We obtain a value of 1.015 memu/g for the saturation magnetization of the pure ZnO nanorod.
Integral image word length reduction using overlapping rectangular regions
Venue: 2016 IEEE International Conference on Industrial Technology (ICIT)

An integral image is a data table whose elements are the sums of pixel values taken from a source image. Using integral images, the total pixel value for any rectangular region in the source image can be calculated at high speeds. However, a large word length is required. In this study, we propose a word length reduction method for the integral image, which is based on the qualities of the integer addition operations. Using overlapping rectangular regions, we are able to reduce the word length and accurately calculate the total pixel values of the rectangular regions. This method can greatly reduce the word length when seeking the total pixel values of a large number of rectangular regions within the image.
Low obstacle detection using stereo vision
Venue: 2016 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS)

Real time obstacle detection is a key component of autonomous vehicles. In this context, low obstacles are particularly challenging, as they are often discarded by traditional algorithms. Curb detection methods that can potentially be suitable for the problem usually target roads with clearly defined curbs and sidewalks. We propose a real time algorithm for the detection of low obstacles (including, but not restricted to curbs) merging 2 D and 3 D information from stereo imaging. A set of candidate object lines is extracted based on their combined 2 D and 3 D features, tracked over time and clustered according to a novel similarity metric. Finally, a 3rd order polynomial spline is fitted to each cluster to represent the obstacle. The proposed system can deal with noisy and incomplete point clouds and keeps the model assumptions to a minimum. To evaluate the algorithm, a new stereo dataset is provided and made available online. We present experiments in different scenarios and lighting conditions, illustrating the applicability of the method.
Sub national Estimates of Human Capital Indicators: Localizing Investments for the Demographic Dividend

Declining fertility in many countries of Africa and Asia combined with a growing proportion of people of working age is opening potential for a demographic dividend in many countries. A demographic dividend is defined as the economic benefit that can arise when a population has a relatively large proportion of working age people coupled with a history of effective human capital investment. Adopting the Global Agenda Council policy framework on achieving a demographic dividend, this research has developed a method for measuring human capital needs at the national and sub national level by using a "demographic dividend index" By mapping the dependency ratios and human capital indicators of the districts of Nepal, this paper illustrates an innovative descriptive method for showing policy makers the priority geographic areas for investments that will maximize prospects for a demographic dividend. Besides the identification of priority districts using the index, the research visualizes the spatial distribution of each indicator, as well as further disaggregates the indicators by urban/rural and gender. This disaggregated data are helpful in identifying the key issues within districts, as well as reducing urban/rural and gender inequality in each district level. The findings provide important insights pertaining to place of residence and gender issues.
Strategic and tactical price decisions in hotel revenue management

Dynamic pricing techniques allow using a number of variables in a tactical way compared to standard catalogue prices. This study merges in a conceptual model the relevance of the tactical and the strategic dimension of these variables, classified according to their tangible, reputational or contextual nature. To empirically validate the hypotheses, a database of 21.596 price observations was retrieved from booking.com The study presents a hedonic price function, using the Shapley Owen decomposition of the R squared to elicit the importance of each group of factors. Further, a hierarchical cluster analysis measures the presence of heterogeneity across operators. The results show that online reputation is gaining importance over the traditional star rating. Despite the tangible variables remain of paramount importance, the findings suggest the relevant role of contextual variables in short run price variations. The players operating in the tourism and hospitality industries should integrate these findings when designing pricing strategies.
An untapped gold mine? Exploring the potential of market basket analysis to grow hotel revenue

Market Basket Analysis identifies and predicts the purchasing behavior of customers based on the expenditure patterns of all previous customers. While widely applied in retail contexts, its use in hospitality is limited. This paper argues that Market Basket Analysis could increase revenue by enabling hotels to determine the most attractive additional products and services (beyond the room type) to offer new and repeat hotel guests. The method's potential is illustrated using five years of internal guest sales records from a luxury hotel group in Australia. Findings point to significant opportunities for hotel operators to use existing stored data to better understand purchasing decision patterns that can significantly increase revenue per transaction. Challenges to adoption and future research suggestions are offered.
Single Image Super Resolution via an Iterative Reproducing Kernel Hilbert Space Method
Venue: IEEE Transactions on Circuits and Systems for Video Technology

Image super resolution (SR) a process to enhance image resolution, has important applications in satellite imaging, high definition television, medical imaging, and so on. Many existing approaches use multiple low resolution (LR) images to recover one high resolution (HR) image. In this paper, we present an iterative scheme to solve single image SR problems. It recovers a high quality HR image from solely one LR image without using a training data set. We solve the problem from image intensity function estimation perspective and assume that the image contains smooth and edge components. We model the smooth components of an image using a thin plate reproducing kernel Hilbert space and the edges using approximated Heaviside functions. The proposed method is applied to image patches, aiming to reduce computation and storage. Visual and quantitative comparisons with some competitive approaches show the effectiveness of the proposed method.
Influence of resin cement shade on the color and translucency of ceramic veneers
Venue: Journal of applied oral science revista FOB

This in vitro study evaluated the effect of two different shades of resin cement (RC A1 and A3) layer on color change, translucency parameter (TP) and chroma of low (LT) and high (HT) translucent reinforced lithium disilicate ceramic laminates.  One dual cured RC (Variolink II, A1 and A3 shade, Ivoclar Vivadent) was applied to 1 mm thick ceramic discs to create thin RC films (100 um thick) under the ceramics. The RC was exposed to light from a LED curing unit. Color change (DE) of ceramic discs was measured according to CIEL*a*b* system with a standard illuminant D65 in reflectance mode in a spectrophotometer, operating in the light range of 360 740 nm, equipped with an integrating sphere. The color difference between black (B) and white (W) background readings was used for TP analysis, while chroma was calculated by the formula C* ab=(a*2+b*2) 1/2 DE of 3.3 was set as the threshold of clinically unacceptable. The results were evaluated by two way ANOVA followed by Tukey's post hoc test.  HT ceramics showed higher DE and higher TP than LT ceramics. A3 shade RC promoted higher DE than A1 shade cement, regardless of the ceramic translucency. No significant difference in TP was noted between ceramic discs with A1 and those with A3 shade cement. Ceramic with underlying RC showed lower TP than discs without RC. HT ceramics showed lower chroma than LT ceramics, regardless of the resin cement shade. The presence of A3 shade RC resulted in higher chroma than the presence of A1 shade RC.  Darker underlying RC layer promoted more pronounced changes in ceramic translucency, chroma, and shade of high translucent ceramic veneers. These differences may not be clinically differentiable.
Conditions for Lorentz invariant superluminal information transfer without signaling

We understand emergent quantum mechanics in the sense that quantum mechanics describes processes of physical emergence relating an assumed sub quantum physics to macroscopic boundary conditions. The latter can be shown to entail top down causation, in addition to usual bottom up scenarios. With this example it is demonstrated that definitions of "realism" in the literature are simply too restrictive. A prevailing manner to define realism in quantum mechanics is in terms of pre determination independent of the measurement. With our counter example, which actually is ubiquitous in emergent, or self organizing, systems, we argue for realism without pre determination. We refer to earlier results of our group showing how the guiding equation of the de Broglie Bohm interpretation can be derived from a theory with classical ingredients only. Essentially, this corresponds to a "quantum mechanics without wave functions" in ordinary 3 space, albeit with nonlocal correlations. This, then, leads to the central question of how to deal with the nonlocality problem in a relativistic setting. We here show that a basic argument discussing the allegedly paradox time ordering of events in EPR type two particle experiments falls short of taking into account the contextuality of the experimental setup. Consequently, we then discuss under which circumstances (i.e. physical premises) superluminal information transfer (but not signaling) may be compatible with a Lorentz invariant theory. Finally, we argue that the impossibility of superluminal signaling despite the presence of superluminal information transfer is not the result of some sort of conspiracy (a la "Nature likes to hide" but the consequence of the impossibility to exactly reproduce in repeated experimental runs a state's preparation, or of the no cloning theorem, respectively.
On the Gamma Ray Bursts Origin

Gamma ray (GRBs) and X ray Bursts are millisecond 10 and 1000 seconds long events of unknown origin. Recent simulations of the merger of binary neutron star systems do not generate a magnetically dominated called funnel nor a relativistic outflow. New models for the detection the afterglow of GRB 121024A, measured 0.15 days after the burst, invoke anisotropy as required to produce the complex microphysics of realistic shocks in relativistic jets. On the other hand the non thermal gamma rays are supposed to be produced by a fireball of relativistic e?e+ pairs that are created by annihilation of neutrino antineutrino pairs in the vicinity of the hot, merged object. It is also known that in a system of a large number of fermions with pairs, gravitational interaction occurs a spontaneous breaking of the vacuum spatial symmetry, accompanied by gravitational mass defect. If spherical symmetry is broken, as in the known case of the merger scenario where a rapidly rotating disk can be formed and material is pulled away from rotation axis by centrifugal forces, then a baryon free funnel along the rotation axes may allow relativistic beam of g's and e?e+ to escape. It might lead to matter ejection with Lorentz factors of ~102 103 which are in the right range to enable copious gamma production during shock interaction with ambient interstellar gas. Here we show that the space rays generation mechanism on a method of direct transformation of intergalactic gamma rays to the proton current on spin shock waves ensure precise agreement between generated proton currents (spin shock waves theory) with the angular distribution data of Galactic gamma rays as well as for the individual pulses of gamma /X ray bursts. There is a precise confirmation of the generated currents (theory) with the burst radiation data characterized by the standard deviation of 1% in intensity in relative units within the sensitivity of the equipment. Thus, it was found that the spin angular momentum conservation law (equation of dynamics of spin shock waves) in the X ray/gamma ranges is fulfilled exactly in real time. The next step involves setting the inverse problem of determining the wave function disturbance on the differential of measured smoothing pulses. In the asymptotic large times the problem is reduced to the solutions of the functional equation with shift of the argument. This will give additional information about the change speed of the wave, as well as on the interaction.

Cutting Force Investigation of Trochoidal Milling in Nickel based Superalloy

The gas turbine, aerospace and nuclear industries are dependent upon nickel based superalloys to enable these industries to continue to innovate. Without these materials the industries would fail to achieve new heights of efficiency as the strength and operating temperature requirements continue to climb. Nickel based superalloys thrive in these elevated temperature applications, where their great resistance to creep and corrosion is coupled with remarkably high strength values. These same characteristics that are invaluable to the final operating environment severely degrade their machinability with high cutting forces and aggressive rate of tool wear. Although the field of machining research is very well established, when it comes to nickel based superalloys there is a large amount of that is yet to be understood. Trochoidal milling has been identified to extend tool life and reduce machining time in the milling of aluminums, however in nickel based superalloys it remains largely unexplored. This work aims to understand the cutting force behavior of milling nickel based superalloys using this alternative milling technique.
Experimental assessment on performance of TiN/TiCN/Al2O3/ZrCN coated tool during dry machining of Nimonic C 263

Nimonic C 263 is one of most important grades of nickel based superalloys particularly used in hot section of gas turbines, aerospace, power generators and heat exchangers. It belongs to the class of difficult to cut materials because of its unique properties such as high hardness, fatigue strength, low thermal conductivity, high chemical affinity and tensile strength along with resistance to corrosion and oxidation. Machinability can be improved with proper selection of cutting tool and cutting parameters. The present paper deals with comparative analysis of tool wear and chip characteristics when machining Nimonic C 263 with uncoated and multilayer coated carbide inserts. Dry turning operation was carried out at two different cutting speeds (Vc) of 51 m/min and 84 m/min with a constant feed (f) of 0.2 mm/rev and depth of cut (ap) of 1 mm. Chip reduction coefficient (z) tool wear, surface roughness and cutting temperature were observed during dry machining of Nimonic C 263. While surface finish could not be improved, remarkable reduction in cutting temperature, chip reduction co efficient and tool wear was noted for the multi layer coated insert under different cutting condition.
