A Characteristic Study on NIPAM Gel Dosimetry Using Optical-CT Scanner

This study investigated the dose characteristics of N-isopropylacrylamide (NIPAM) polymer gel dosimetry in intensity-modulated radiation therapy (IMRT). The NIPAM gel was composed of 5% gelatin, 5% NIPAM, 3% Bis, and 5 mM tetrakis (hydroxymethyl) phosphonium chloride (THPC). The gel was poured into a cylindrical acrylic phantom with a diameter of 10 cm, a height of 10, and a wall thickness of 3 mm. The gel phantom was irradiated with IMRT. The phantom energy was 6 MV and the dose rate was 250 MU. The NIPAM gel was scanned using an optical computed tomography (CT) scanning system. In terms 2of uniformity, the intra-dosimeter showed a consistent dose profile at different depths and a deviation of less than 1.8%. The scanning results showed a consistent dose distribution for each scanning experiment. The percentage isodose lines from the measured data agreed well with those from the treatment planning system (TPS) at 60% to 100% dose level region which is acceptable for clinical applications. Gamma index analysis was performed for representative gamma comparison between the TPS and the measurement results. The acceptance pass rate was calculated for various criteria. The pass rates were as high as 99.5% and 97.8% with 5%/5 mm and 4%/4 mm gamma acceptance criteria, respectively. The results indicate that a NIPAM polymer gel dosimeter can be used in conjunction with optical CT as a dose verification tool, especially for three-dimensional dose verification.

Modelling the Monthly and Annual Temperature Series of Quetta, Pakistan

The monthly average temperature series of Quetta – Pakistan from 1950 – 2000 is examined. A straight line is fitted to the data and seasonal variation and trend in temperature for each month of the year were obtained. An overall model is constructed as large variations in the monthly slopes were observed. In order to describe the seasonal pattern and trend in temperature, corresponding to the different months, both sine/cosine waves and sine/cosine waves multiplied by the time were included in the model as independent variables. The lag-1 autocorrelation was found in the residual of the model and hence another model was fitted to the pre-whiten series that shows a good fit ( ) and is free from correlated residuals. Both parametric and non-parametric tests applied to each month temperature show significant trend in all months except February and March.
A model for performance enhancement in competitive cycling

A 3D cycling model is presented that combines bicycle dynamics, a tyre model, rider biomechanics and environmental factors into a single dynamic system. The system is constructed using Matlab toolboxes (SimMechanics/Simulink) with the aim of identifying mechanical mechanisms that can influence performance in a road cycling time trial. Initial conditions are specified and a variable step ODE solver numerically integrates solutions to the equations of motion. Initial validation compared rider-less self-stability presented in a published “benchmark” with model simulation and found an error of <1.5%. Model results included the weave eigenvalue becoming negative at 4.2 m/s and the capsize eigenvalue approaching a positive value at 6.1 m/s. The tyre model predicted peak front tyre slip and camber forces of 130 N and 17 N respectively which were within 0.9% of values reported in the literature. Experimental field validation compared actual and model predicted time taken by 14 experienced cyclists to complete a time trial over an undulating 2.5 mile road course. An error level of 1.4% (±1.5%) was found between actual and predicted time. This compares well with the average 1.32% error reported by existing road cycling models over simpler courses.

Aquaculture Monitoring and Control Systems for Seaweed and Fish Farming

This paper reviews aquaculture monitoring and control systems for seaweed and fish farming. Seaweeds farming play an important role in business and constantly growing. Seaweed is considered to be second largest freshwater farming industry in the world. Not only seaweeds are eaten raw, but through industrial process, some components are extracted to use in other foods. This paper provides 5 types of seaweed species and their aquaculture methods that are very popular. Also we have reviewed, the per capita fish consumption (region-wise), global annual fish production, global fish production in past 60 years, fish production in percentage by region, global seaweed production, seaweed value and important seaweeds for industrial use. Implication of technology such as the Recirculating Aquaculture System (RAS) integrated with sensors, pumping system and filtering mechanism to measure, control and eradicate parameters, variables, and wastes developed by academic institution that has already been demonstrated was reviewed. Typical specification of a 4-tank based RAS is given. The paper also provides an advanced monitoring and control architecture that can be capable of automating precise production processes. Details about the control hardware such as sensors, motors, pumps, electronics, computer and software are presented.
Voltage and Current Wave Behaviour on Transmission-Line Network With Cross-Junction Discontinuities

A simple time-domain numerical analysis of transmission line networks with cross-junction discontinuities is presented. The numerical method bases on the modified central difference technique, in which the internal boundary treatment introduced the time-domain scattering matrix is carried out for the cross junction of the internal line discontinuity. The voltage and current wave propagation on the whole transmission line network model of the lattice-line hybrid are demonstrated to clarify the microwave circuit operation and the time domain reflectometry. The efficient simulation technique has been required in the system design of transmission line network models, such as planar type microwave circuits and antennas including various line discontinuities. It is very important to analyze the behaviour of the propagation signal over the transmission lines in the planar circuit systems, so it has to clarify the circuit operation and the reflection characteristic in terms of the time-domain analysis. Many analytical and numerical techniques for obtaining input/output responses of the planar type microwave circuits have been described in [1]. Then, the three-dimensional electromagnetic field analysis simulators, such as the finite element method, the method of Moment, and the FD-TD method [2], have also reported in many researches. However, their approaches relatively take much more CPU time and memory requirements for obtaining the time-domain solutions of the voltage and current waves propagation on the transmission line networks with the various line discontinuities, such as branch-line couplers, hybrid rings and so on. Here, we apply the modified central difference (MCD) method with the boundary treatments combining the time-domain scattering matrix formulation to analyze the transmission line network including cross-junction discontinuities. By using this new time-domain simulation technique, the signal propagation, reflection and the standing waves of the lattice-line hybrid can be represented for various excitation wave forms. Namely, it is shown that from the simulated results, the behaviour of the propagation signals and reflections for the voltage and current waves are easily clarified by visualizing the time-domain solutions. The aim of this paper is to present a simple simulation technique for visualising signal propagation on the transmission line network with cross-junction discontinuities. It is show that this numerical approach is useful to analyze the transient responses and the transition of the voltage and current distributions on the whole transmission line network model, e.g. the lattice-line hybrid directional coupler. The behaviour of the signal propagation and reflection is demonstrated to confirm the circuit operation including multiple reflections caused by each of the junction. This method can be used for educational and engineering purposes sufficiently.
NETWORKS AND INTERMEDIARIES IN SEASONAL AGRICULTURAL LABOR MARKETS IN TURKEY

In casual labor markets, intermediaries are used in order to match employers and employees. This function is especially important when the market is imperfect and employers and employees have not formed solid networks. This paper investigates the network effects and the role of intermediaries in the seasonal agricultural labor market in the irrigated area of Adana, Turkey. The network of rural households is divided into one composed mainly of farmers and one composed mainly of seasonal agricultural workers. Our regression analyses show that the seasonal workers who do not have strong networks with farmers have difficulty finding jobs. Middlemen serve to mitigate the seasonal workers’ lack of a network and play a key role in the area’s seasonal agricultural labor market. At the same time, however, blood ties and territorial ties between middlemen and workers may cause middlemen to discriminate among seasonal workers based on their origins.
On the Labeling Correctness in Computer Vision Datasets

Image datasets have heavily been used to build computer vision systems. These datasets are either manually or automatically labeled, which is a problem as both labeling methods are prone to errors. To investigate this problem, we use a majority voting ensemble that combines the results from several Convolutional Neural Networks (CNNs). Majority voting ensembles not only enhance the overall performance, but can also be used to estimate the confidence level of each sample. We also examined Softmax as another form to estimate posterior probability. We have designed various experiments with a range of different ensembles built from one or different, or temporal/snapshot CNNs, which have been trained multiple times stochastically. We analyzed CIFAR10, CIFAR100, EMNIST, and SVHN datasets and we found quite a few incorrect labels, both in the training and testing sets. We also present detailed confidence analysis on these datasets and we found that the ensemble is better than the Softmax when used estimate the per-sample confidence. This work thus proposes an approach that can be used to scrutinize and verify the labeling of computer vision datasets, which can later be applied to weakly/semi-supervised learning. We propose a measure, based on the Odds-Ratio, to quantify how many of these incorrectly classified labels are actually incorrectly labeled and how many of these are confusing. The proposed methods are easily scalable to larger datasets, like ImageNet, LSUN and SUN, as each CNN instance is trained for 60 epochs; or even faster, by implementing a temporal (snapshot) ensemble.
Chemical abundances in a high velocity RR Lyrae star near the bulge

Low-mass, variable, high-velocity stars are interesting study cases for many aspects of Galactic structure and evolution. Until recently, the only known high- or hyper-velocity stars were young stars thought to originate from the Galactic centre. Wide-area surveys like APOGEE and BRAVA have found several low-mass stars in the bulge with Galactic rest-frame velocities larger than 350 km/s. In this study we present the first abundance analysis of a low-mass, RR Lyrae star, located close to the Galactic bulge, with a space motion of ~ -400 km/s. Using medium-resolution spectra, we derive abundances (including upper limits) of 11 elements. These allow us to chemically tag the star and discuss its origin, although our derived abundances and metallicity, at [Fe/H] =-0.9 dex, do not point toward one unambiguous answer. Based on the chemical tagging, we cannot exclude that it originated in the bulge. However, combining its retrograde orbit and the derived abundances suggests that the star was accelerated from the outskirts of the inner (or even outer) halo during many-body interactions. Other possible origins include the bulge itself, or the star could be stripped from a star cluster or the Sagittarius dwarf galaxy when it merged with the Milky Way.
Energy-Aware Replica Selection for Data-Intensive Services in Cloud by

Energy-Aware Replica Selection for Data-Intensive Services in Cloud Bo Li, M.S. Rochester Institute of Technology, 2012 Supervisor: Dr. Ivona Bezáková With the increasing energy cost in data centers, an energy efficient approach to provide data intensive services in the cloud is highly in demand. This thesis solves the energy cost reduction problem of data centers by formulating an energy-aware replica selection problem in order to guide the distribution of workload among data centers. The current popular centralized replica selection approaches address such problems but they lack scalability and are vulnerable to a crash of the central coordinator. Also, they do not take total data center energy cost as the primary optimization target. We propose a simple decentralized replica selection system implemented with two distributed optimization algorithms (consensus-based distributed projected subgradient method and Lagrangian dual decomposition method) to work with clients as a decentralized coordinator. We also compare our energy-aware replica selection
The Value of Protecting Venice from the Acqua Alta Phenomenon Under Different Local Sea Level Rises

Venice (Italy) is built on several islands inside a lagoon. It undergoes a periodical �ooding phenomenon, called "Acqua Alta" (AA). A system of mobile dams, called Mo.S. E. , is currently under construction to protect it. When needed, several fl�oodgates will be lifted to separate the lagoon from the Adriatic sea. AA, whose length and height has been increasing in recent years, is a random phenomenon, correlated with local sea level rise (LSLR). Several possible LSLRs can be assumed as consequences of different global warming scenarios. We investigate here the cost-bene�t of Mo.S. E. under different possible LSLRs. First, we simulate the future patterns of AA for the next 50 years under alternative LSLRs. Then, we calculate the bene�t of Mo.S. E. , converting each avoided AA episode into an economic value (avoided cost). We show that the bene�ts are just at the level of the costs, when a low LSLR is assumed and increase with LSLR, provided that it does not reache a catastrophic (yet unpredictable) extreme level.
Title An enhanced MITOMAP with a global mtDNA mutational phylogeny Permalink

The MITOMAP (http://www.mitomap.org) data system for the human mitochondrial genome has been greatly enhanced by the addition of a navigable mutational mitochondrial DNA (mtDNA) phylogenetic tree of 3000 mtDNA coding region sequences plus expanded pathogenic mutation tables and a nuclear-mtDNA pseudogene (NUMT) data base. The phylogeny reconstructs the entire mutational history of the human mtDNA, thus defining the mtDNA haplogroups and differentiating ancient from recent mtDNA mutations. Pathogenic mutations are classified by both genotype and phenotype, and the NUMT sequences permits detection of spurious inclusion of pseudogene variants during mutation analysis. These additions position MITOMAP for the implementation of our automated mtDNA sequence analysis system, Mitomaster.
Simulating , animating and rendering clothes

This paper presents a retrospective of past work in the field of cloth simulation and rendering. Cloth animation is crucial for the rendering of a scene involving virtual actors. Over the years a broad range of methods have been proposed to animate cloth in a fast and stable way. Furthermore, collisions of the cloth, either with itself or other objects in the scene are a challenging area. To date a variety of work has been published about how to efficiently detect and resolve collisions. The internal microstructure of cloth makes it difficult to render garments in a fast and sophisticated way. Special rendering techniques to overcome the problems will therefore be reviewed. The availability of programmable GPUs has resulted in a great body of work about real-time simulation of cloth on graphics hardware.
Beginning Teacher Knowledge: Results from a Self-Assessed TPACK Survey.

For over twenty years teachers in Australia and internationally have been encouraged to use ICT in their practice. Various government policies have been implemented to provide the technical means for teachers to do so as well as numerous teacher professional learning programs, often skills based, short term and off site. Yet teacher uptake of technologies in their routine classroom practice continues to be slow and uneven, with pre-service teacher education sometimes bearing the brunt of blame. The TPACK framework developed by Mishra and Koehler (2006) has emerged as an influential tool for describing the knowledge teachers need to integrate technology into their practice. This paper reports on a survey which measured the TPACK knowledge of sixty-four beginning teachers in Victoria, Australia. This data was analysed to reveal how beginning teachers self-assessed their knowledge in each of the seven domains, as well as to explore patterns by gender. As a result of these findings several suggestions for pre-service teacher education are made.
G305.136+0.068: A MASSIVE AND DENSE COLD CORE IN AN EARLY STAGE OF EVOLUTION

We report molecular line observations, made with ASTE and SEST, and dust continuum observations at 0.87 mm, made with APEX, toward the cold dust core G305.136+0.068. The molecular observations show that the core is isolated and roughly circularly symmetric and imply that it has a mass of 1.1 × 103 M☉. A simultaneous model fitting of the spectra observed in four transitions of CS, using a non-LTE radiative transfer code, indicates that the core is centrally condensed, with the density decreasing with radius as r−1.8, and that the turbulent velocity increases toward the center. The dust observations also indicate that the core is highly centrally condensed and that the average column density is 1.1 g cm−2, a value slightly above the theoretical threshold required for the formation of high-mass stars. A fit to the spectral energy distribution of the emission from the core indicates a dust temperature of 17 ± 2 K, confirming that the core is cold. Spitzer images show that the core is seen in silhouette from 3.6 to 24.0 μm and that it is surrounded by an envelope of emission, presumably tracing an externally excited photo-dissociated region. We found two embedded sources within a region of 20″ centered at the peak of the core, one of which is young, has a luminosity of 66 L☉, and is accreting mass with a high accretion rate of ∼1 × 10−4 M☉ yr−1. We suggest that this object corresponds to the seed of a high-mass protostar still in the process of formation. The present observations support the hypothesis that G305.136+0.068 is a massive and dense cold core in an early stage of evolution, in which the formation of a high-mass star has just started.
Therapist or Anything , I ’ ll Immediately Scope Them Out ” : Anorexia Nervosa Clients ’ Perceptions of Their Therapist ’ s Body Journal Item

Although people with an eating disorder are known to observe and assess body related stimuli, research has yet to explore these behaviors in the therapy room. Consequently, practitioners do not know if their body is having an impact on their client or the therapy process. This lack of knowledge is problematic given the poor recovery rates and high levels of drop out in eating disorders treatment. Using semi-structured interviews this study investigated the beliefs and experiences of 11 women diagnosed with anorexia nervosa or bulimia nervosa with a history of restricting who had received counseling from a female therapist. Results derived from a thematic analysis suggested that the women not only observed, speculated and made assumptions about their therapist’s body but also that their assumptions and speculations had the potential to influence both their beliefs about the therapist’s ability to help them, and their willingness to engage in therapy.
Advanced interpretation of land subsidence by validating multi-interferometric SAR data: the case study of the Anthemountas basin (Northern Greece)

Abstract. The potential of repeat-pass space borne SAR (Synthetic Aperture Radar) interferometry has been exploited to investigate spatial patterns of land subsidence in the Anthemountas basin, in the northern part of Greece. The PSI (Persistent Scatterer Interferometry) approach, based on the processing of long series of SAR acquisitions, has been applied to forty-two images acquired in 1995–2001 by ERS1/2 satellites. Interferometric results have been analysed at a basin scale as support for land motion mapping and at a local scale for the characterisation of ground motion events affecting the village of Perea in the Thermaikos municipality and the "Macedonia" international airport. PSI results revealed a moderate subsidence phenomenon along the wider coastal zone of Anthemountas basin corresponding to intense groundwater extraction. Highest values, exceeding −20 mm yr−1, were measured in the airport area where the thickest sequence of compressible Quaternary sediments occurs. Intense subsidence has been detected also in the Perea village (maximum deformation of −10 to −15 mm yr−1), where a series of fractures, causing damages to both buildings and infrastructure, occurred in 2005–2006.
