Path-average kernels for long wavelength traveltime tomography

SUMMARY Although much effort goes into improving the resolution of tomographic models, investigating their quality has only just started. Probabilistic tomography provides a framework for the quantitative assessment of uncertainties of long-wavelength tomographic models. So far, this technique has been used to invert maps of surface wave phase velocities and normal-mode splitting functions. Including body waves would substantially increase the depth resolution in the lowermost mantle. In surface wave tomography, the construction of phase velocity maps and splitting functions is a well-defined inverse problem, and the depth inversion is less well constrained but characterized by a small number of dimensions suitable for a Monte Carlo search. Traveltime tomography is mostly based on ray theory that covers the 3-D Earth, thus the dimension of the inverse problem is too large for a Monte Carlo search. The ray-mode duality suggests to apply the path-average approximation to body wave traveltimes. In this way the measured traveltime residual as a function of ray parameter can be inverted using path-average kernels, which depend on depth only, similar to surface wave tomography. We investigate the validity of the path-average approximation for delay times in both the forward and the inverse problem using the velocity model S20RTS as well as random models. We numerically illustrate the precision of such kernels compared with ray-theoretic and finitefrequency ones. We further invert traveltime residuals, calculated from Fermat rays, using the path-average kernels. We find that the agreement between classical ray theory and path-average theory is good for long wavelength structures. We suggest that for mapping long wavelength structures, body waves can be inverted in two steps, similar to surface waves, where the ray parameter and the vertical traveltime play the role of frequency and phase velocity, respectively.
Chartering Predictive Analytics : A Case Study Full paper

Many organizations are implementing analytics projects. Unfortunately, most big data projects fail, and the reasons are not well understood (LaValle et al. 2013). This paper studies the chartering phase of a predictive analytics project to further our understanding of big data projects. We conduct a qualitative study at a large supply chain company. We employ a variety of qualitative research techniques, including participant observation and interviews of key project personnel. In particular, we conduct a case study of the company’s predictive analytics journey and the challenges it encountered. These include corporate governance, vendor relationships, and lack of data. This research adds insight into why companies implement predictive analytics projects and the challenges they face. The study makes several contributions to the IS literature by adding a qualitative perspective to the big data field, which is dominated by quantitative studies, and focusing on the chartering phase of project implementation.
Testing Predator-Prey Theory by Studying Fluctuating Populations of Small Mammals

Fluctuating populations of small mammals provide an excellent opportunity to study the functional and numerical responses of predators because of the wide range in prey density that occurs. I reinterpret data from six studies that have examined the role of predation in the population dynamics of voles in California, southern Sweden and western Finland, of snowshoe hares in northern Canada, and of house mice and rabbits in Australia. Most studies have measured functional responses by relying on changes in diet as reflected by scat or stomach contents. These methods are probably biased toward showing predator satiation. Contrary to previous conclusions I find that there is little evidence for non-linear (Type 111) functional-response curves or predator satiation at high prey densities. Recent studies indicate that the functional and numerical responses of predators can be rapid and strong enough to initiate cyclic declines, dampen fluctuations, or even cause stable numbers. The exception to this appears to be the irruptions of mice and rabbits in Australia. I propose a general explanation for the role of predation whereby the effect of predation is largely dependent on the entire prey community. When potentially cyclic prey are a small component of the overall prey biomass, generalist predators are able to prevent fluctuations by strong functional or numerical responses. As the prey community becomes dominated by a few species that fluctuate, limit cycles predominate. Limit cycles turn into irruptive population dynamics when seasonal prey reproduction is eliminated because of extended periods of vegetation growth (vegetation flushes following drought). In the future we must test assumptions underlying the way we study predation by telemetric monitoring of prey mortality and by experimentally manipulating predation.
Evaluation of selected mutants of grasspea (Lathyrus sativus L.) var. Krab as an ingredient in broiler chicken diet

The aim of the study was to evaluate the nutritional value of Lathyrus sativus var. Krab in broiler chickens as well as that of 3 mutants (K-12, K-63 and K-64) developed from var. Krab by mutagenic treatment and selection towards improved agronomic traits. The proximal composition of mutants was similar to that of var. Krab with the exception of a higher protein content in K-12, and lower β-N-oxalyl-L-α,β-diaminopropionic acid (ODAP) and tannin contents in the mutants. Trypsin inhibitor activity ranged from 57 to 68 mg/g crude protein (CP) in mutants, and equaled 72 mg/g CP in Krab variety seeds. Four test diets composed using the basal diet and evaluated grasspea seeds at a proportion of 6:4 were used in the balance experiment; the control diet without grasspea, and 4 isonitrogenous diets containing 10% grasspea were used in the growth experiment. Apparent total tract protein digestibility and metabolizable energy in mutant K-12 equaled 72% and 9.8 MJ ME/kg DM, respectively, and were similar as in var. Krab but higher than in mutants K-63 and K-64 (P<0.05). In chickens fed from day 8 to 40 of age diets containing 10% grasspea, performance, tibia ash content, and tibia ultimate strength did not differ from the control group. However, birds fed the diet with var. Krab seeds had enlarged pancreases (P<0.05) and livers in comparison with controls; the weight of these organs was lower (P<0.05) in groups fed mutant seeds. Bone and joint deformations indicative of neurolathyrism were found in four birds from the group fed var. Krab, while they were not seen in birds fed the diets with seeds from mutants.
Precision vector control of a superconducting RF cavity driven by an injection locked magnetron

The technique presented in this paper enables the regulation of both radio frequency amplitude and phase in narrow band devices such as a Superconducting RF (SRF) cavity driven by constant power output devices i.e. magnetrons [1]. The ability to use low cost high efficiency magnetrons for accelerator RF power systems, with tight vector regulation, presents a substantial cost savings in both construction and operating costs - compared to current RF power system technology. An operating CW system at 2.45 GHz has been experimentally developed. Vector control of an injection locked magnetron has been extensively tested and characterized with a SRF cavity as the load. Amplitude dynamic range of 30 dB, amplitude stability of 0.3% r.m. s, and phase stability of 0.26 degrees r.m.s. has been demonstrated.
FROM THE COGNITIVE PARADiGM

The paper identifies a paradigm shift in researcl. on teaching effectiveness from the process-product approach tc explanations from cognitive psychology related to mediating variables which intervene between teacher behavior and pupil performance. Implications of this paradigm shift for research on the effectiveness of teachers of deaf students are arawn. Research on predictors of student outcomes with deaf students has tended to focus on background chFracteristics of students or on the effecrs of school placement in a very superfic: . 1 way. Few studies hae investigated the mediating variables betweeh teachers and their hearing impaired students. A set of recommendations linking research on teacher effectiveness with the cognitive psychology framework in the cc \text of deafness education is offered. The docdment notes the importance of providing feedback to teachers about their students' behavior and thinking in improving teaching outcomes. Researchable topics related to ,,tudent and teacher thought processes SU7n as student and teacher expectations, attention, motivation, memory, comprehension and knowledge acquisition, learning strategies, and metacognitive processes are identified. Modifications necessary for dealing with a deaf population are addressed for describing tne reaching-learning process from the cognitive perspective.

State of the art in chromovitrectomy Estado da arte da cromovitrectomia

Vitrectomy is a surgery that involves complex and delicate techniques that treat diseases such as macular hole, epiretinal membrane and diabetic macular edema. Chromovitrectomy is one of these techniques and includes the use of coloring agents such as vital dyes or crystals to enhanced visibility of transparent structures during vitrectomy. The aim of this study was to present a modern approach, based on scientific evidence, about the application and indication of vital coloring agents during vitrectomy. The use of such agents has made this surgery more predictable and has increased its post-operative prognosis. Although research on chromovitrectomy is currently expanding there is still not an established gold standard dyeing agent.

Public Opinions on Strategies for Managing Stray Cats and Predictors of Opposition to Trap-Neuter and Return in Brisbane, Australia

A survey of Brisbane residents was undertaken to investigate community attitudes toward urban stray cats and their management. Surveys were distributed to 84 medical and dental practices across Brisbane City, and were completed by 305 patients and staff. Practices were targeted to achieve a sample of respondents from a representative distribution of socioeconomic backgrounds. After being informed about trap, neuter, and return (TNR) programs for management of urban stray cats, most respondents (79%), chose TNR as their preferred management strategy, while a lesser proportion (18%) expressed a preference to continue the current Brisbane City Council lethal control program (catching and culling ~1,000 cats annually), and 3.4% selected to leave the cats alone. Differences in beliefs and attitudes toward urban stray cats as a function of demographic variables were investigated. Statistical analyses indicated that respondents who were male, older, non-cat owners, those who believed euthanasia of stray cats was humane, and that urban stray cats spread disease to humans were significantly more likely to express a preference for lethal control, as opposed to non-lethal population management. Based on these findings, we recommend that information is disseminated to mitigate these concerns or negative beliefs, where warranted. Ultimately, findings from this study demonstrate that current Queensland legislation does not reflect public views and opinions on stray cat management and should be reviewed. Formal research evaluating the efficacy of TNR programs for urban stray cats in Australia would be in the public interest.
Diagnosis of turbulence radiation interaction in turbulent flames and implications for modeling in Large Eddy Simulation

An ap rioristudy of the turbulence radiation interaction (TRI) is performed on numerical data from Direct Numerical Simulation (DNS) of a turbulent flame. The influence of the various correlations that appear in the radiative emission is investigated and their impact is evaluated in the context of Large Eddy Simulation (LES). In LES, only filtered quantities are computed, where the filter is the grid. The radiative emission is reconstructed first from the exact, then filtered solution variables and the sensitivity to the filter size is evaluated. Three approaches are used to take into account the subgrid scale correlations: the no-TRI, partial TRI and full TRI approaches. Results show that the full TRI is exact compared to the reference emission and that the partial TRI performs worse than the no-TRI for the studied configuration. This indicates that in the studied case, the TRI must be considered in LES in a full formulation.
Comparison Of Standard And Image-filter Fusion Techniques

Image fusion in a general sense, can be defined as:’<the combination of two or more dljlerent images to form a new image by using a certain algorithm” [1]. It aims to extract flom a set of different images of the same area those properties which are unavailable by the single sensor and which form in a combined way a new image with a higher multispectral resolution. In standard image fusion one multispectral image band is entirely substituted by the panchromatic band. It is not new, however, that due to the incoherence of sensor performances the original multispectral information becomes distorted and hence, the data provides only limited use in the spectral classification of textural image information. In comparison, newly evolved image filter data fusion techniques preserve both spatial and multispectral information. Results of both techniques are shown here using a higher resolution panchromatic image (IRS-1 C) and a lower resolution multispectral image (SPOT XS). In detail, this paper discusses on one side the performance of three standard image fhsion techniques, Intensity Hue Saturation (IHS), Principle Component Analysis (PCA) and High Pass Filter (HPF) and on the other side the use of a newly evolved image fusion technique, the Adaptive Image Filter (AIF) fksion. Results are visually assessed for image interpretability and statistically for spectral classification of textural data. From this assessment the IHS and PCA fusion achieved similar good results for visual image interpretation. If fused images are used for subsequent image classification, then the AIF fhsion is the preferable one, preserving the multispectral information while adding textural and structural detail. © 2002 WIT Press, Ashurst Lodge, Southampton, SO40 7AA, UK.

Passwords Management via Split-Key

This paper proposes a scheme for password management by storing password encryptions on a server. The method involves having the encryption key split into a share for the user and one for the server. The user’s share shall be based solely on a selected passphrase. The server’s share shall be generated from the user’s share and the encryption key. The security and trust are achieved by performing both encryption and decryption on the client side. We also address the issue of countering dictionary attack by providing a further enhancement of the scheme.

Automated Image Segmentation Methods for Digitally-Assisted Palaeography of Medieval Manuscripts

We explore methods of automating the digital palaeographic process, using a divide and conquer approach. Firstly, image noise is reduced using a combination of colour removal, and varied blurring and thresholding techniques. Initial values for these processes are calculated by the system based on the average greyscale colour of the image upon initial importation. By combining these algorithms, the system is able to achieve high levels of noise reduction. The process of segmenting the script into letters is also divided. First, blocks of text are detected in the noise-reduced image, by measuring the proportion of black pixels within predefined sized blocks of pixels, comparing these values to the average colour values of not only the entire image, but the surrounding blocks (minimising false positive rates). These blocks of text are split into individual lines through detection of whitespace, and then further segmented into individual letters, through a similar technique. In order to verify the integrity of the letters, the sizing of each segment is compared to the letter average (since most letters within manuscripts are of a similar width). Any letters excessively differential to this average, are then re-checked, by re-performing the segmentation algorithms in these specific locations with thresholding set to both lighter and darker levels. The results of these segmentations are then merged, with each box finally being expanded to fit the letter more precisely.
