Facilitating the Inclusion of Children With Vision Impairment: Perspectives of Itinerant Support Teachers
Authors: Morris Christine , Sharma Umesh 
Published: December 2011

AbstractChildren with vision impairment (VI) and blindness are largely educated in mainstream schools in Australia. Specialist itinerant support teachers – vision (ISTVs) travel from school to school to facilitate the education of these children. The purposes of this study were to examine the barriers that ISTVs face in this role, and to identify strategies used to address these barriers. Seven ISTVs participated in the study. Focus group interviews were conducted to collect data from participants. Constant comparison, a form of thematic analysis, was used to examine the data. Results indicate that barriers include a lack of understanding among regular school educators of the needs of children with VI, lack of awareness of the role of ISTVs, insufficient resources and time, and inadequate training. Frequent communication and good working relationships with staff help to minimise or negate many of the potential barriers. However, barriers such as lack of time and inadequate training remain unaddressed and require the attention of policymakers at higher levels.
Commentary on Carter, Stephenson and Strnadová's Reported Prevalence by Australian Special Educators of Evidence-Based Instructional Practices
Authors: Dempsey Ian 
Published: December 2011

AbstractIn Volume 35, Issue 1 of the Australasian Journal of Special Education, Carter, Stephenson and Strnadová (2011) replicated a study by Burns and Ysseldyke (2009). In Carter et al.'s study, 194 Australian special educators were asked to rate the extent to which they used eight instructional practices. These practices were applied behaviour analysis, direct instruction, formative evaluation, mnemonic strategies, modality training, perceptual-motor training, psycholinguistic training, and social skills training. The first four of these practices had moderate to high effect sizes (and were regarded by the authors as more desirable techniques), and the final four practices had low effect sizes, on the basis of past meta-analytic research. Carter et al.'s findings were that while the Australian teachers used some desirable strategies relatively frequently, they also used some less desirable practices frequently and so desirable instructional practices should be encouraged at the expense of less effective practices. While these results are of interest, they also have the potential to mislead readers and later sections of the current article examine these potential misconceptions.

Informational Advantages and Accuracy Characteristics of the Adaptive Well Log Data Interpretation
Authors: Kozhevnikov D. A. , Kovalenko K. V. , Deshenenkov I. S. 
Published: December 2011

Abstract
The adaptive technology of log data interpretation provides heterogeneous reservoirs evaluation in case of framework and clayey cement polymineral composition, notably clastic reservoir rocks. Values of apparent and total porosity are informativeless for such reservoirs. Petrophysical invariant (normalized effective or dynamic porosity) is applied as an interpretative parameter. It characterizes static reservoir properties as well as filtration properties.
Proposed petrophysical models use minimum number of physically measureable variables (from core data or from prior petrophysical information about simulated object in core data shortage conditions), which tune interpretation algorithms with high accuracy description of reservoir rocks properties diversity. Effective porosity is estimated using adaptive interpretation of logging data. This procedure is conducted according to characteristic responses derived from each standard log (spontaneous potential, sonic, natural radioactivity, density and neutron logs). Then heterogeneous reservoir properties transfer to geological model.
Adaptive technology advantages include following: the technology could be applied for rapid interpretation of log data large volumes; effective porosity could be calculated for complex polymineral reservoirs in absolute units without "reference beds"; the technology provides adaptive tuning on lithological and petrochemical conditions of the particular reservoir in situ, including the wellbore construction influence; it could be used for the old data re-interpretation. Thus, the adaptive log data interpretation practical importance is due to the radical reduction of the error sources number inherent to the conventional technology.
The effective porosity prediction from standard log data is an important link in the chain of modern exploration and production activities. Its implementation determines how accurate and detailed a geological model will be and it definitely affects both reserves estimation and the design of a field development plan.
Wellbore Anti-Collision Safety: Separation Distances Must Be Increased Due To Degraded Positioning Accuracy In Northern Areas
Authors: Bang J.. , Torkildsen T.. 
Published: December 2011

Abstract
The magnitudes of certain significant error terms vary with latitude, for both magnetic and gyroscopic surveying instruments. This implies an increase in surveyed azimuth uncertainty, as one moves into northern regions.
This work analyzes the influence of the uncertainty increase on the required separation distance between wellbores. An expansion factor Fφ2/φ1 is presented, defined as the factor that scales a separation distance from latitude φ1 to latitude φ2, provided that the confidence level, and thus the collision risk, remains the same.
Uncertainty analysis incorporating a broad range of wellbore profiles and several magnetic and gyroscopic surveying instruments has been carried out. The results show that Fφ2/φ1 can range from 1.35 to above 2.0, when moving from 60°N (North Sea region) to 75°N (Barents Sea region). If expansion factors of these magnitudes are ignored, the collision risk typically increases by a factor of 10 to 50, respectively. These numbers show that it is of vital importance to apply the correct latitude dependency in wellbore surveying error models, when planning drilling activities in arctic regions.
Methodology to Assess Thaw Subsidence Impacts on the Design and Integrity of Oil and Gas Wells in Arctic Regions
Authors: Xie J.. , Matthews C. M. 
Published: December 2011

Abstract
Over the past decade, petroleum operators have shown increased interest in exploring and developing oil and gas reservoirs in both onshore and offshore Arctic areas. In many cases, the reservoirs are known to be overlain by massive permafrost layers on the order of 50 to 700 m thick. These conditions create unique design and operation challenges for production and injection wells from the perspective of ensuring that well integrity will not be compromised by the inevitable thaw subsidence of the permafrost soil layers.
This paper presents a methodology for modeling and analyzing the severe casing loading and deformation conditions that can occur under thaw subsidence loading. The well design and evaluation methodology includes several sequential steps as follows: wellbore hydraulic and heat transfer analysis, to determine the heat input to the permafrost interval along the well(s) due to either the production of hydrocarbons or water injection; geothermal and geomechanical analyses, to calculate the extent of the permafrost thaw and the resultant thaw-induced soil stresses and movements; and casing-formation interaction analyses, to establish the structural response and evaluate the mechanical and hydraulic integrity of the well casing under the thaw subsidence loads. Sequential thermal and displacement analysis models are used to establish the extent of the thaw boundary that develops with time around the well(s) and the associated thaw subsidence response of the individual soil layers. These results serve as inputs to the non-linear analyses used to assess casing integrity. Examples are used to demonstrate the potential for thaw subsidence movements to cause casing failures, as a result of excessive compressive strains, buckling or large lateral deformations, in both single and multiple well layout scenarios. The methodology presented is recommended for optimizing well completion designs to minimize the potential for such failures to occur.
Permafrost and Other Geohazards of Arctic Offshore
Authors: Bondarev V. N. , Loktev A. S. 
Published: December 2011

Abstract
Arctic Shelf hydrocarbon reserves are estimated over 100 billiard t (in oil equivalent) by different experts when most part of them are in Barents, Pechora and Kara seas [Kliewer G., 2006, www.gazflot.ru]. Obviously offshore oil and gas fields will be intensively developed at the next decades. And the process has being in progress if take in mind started exploration offshore Sakhalin, and ice gravity platform "Prirazlomnaya" has left Murmansk Aug 18, 2011 (when first well to be drilled until end of 2001 as per planning) [www.gazprom.ru]. And soil investigations are completing for Shtokman project design and construction.
That is why problems of environment study and forecast for designing and construction are getting special value and significance. When name "environment" we have to understand it means three components: atmosphere, hydrosphere and lithosphere; they all have some specificity in the area.
Sever climate with long period of negative temperature and strong continuous winds, influence of hydrodynamic and ice factors, specific soil extend, permafrost and post cryogenic processes are the features. The main geo hazards spread along Arctic Shelf are caused by acting of: -oceanlogical factors (wave, wind, tide, etc),-ice, icebergs, stamukhas, hummocks,-lithodynamic influence,-subbotom permafrost and post cryogenic processes,-tectonics and seismicity,-anthropogenic factors,-structure of soil section (weak and non-homogenic soils, specific deposits),-sea bottom morphology features (variability of sea flour, water depth etc).It should be noted phenomena and processes of water and air mediums have been recording over centuries by man already and that is why they are learnt enough. The main problem come up at engineering-oceanlogical investigation is reliability of forecasts to be a function of observation duration first of all.
Normative documents of GOSSTROI and POSGIDROMET specify the period as 1 to 5 years for production facilities of oil and gas industry. However there are no such continuous and long-term investigations in Arctic Shelf (complete series should include around-year period with extreme and moderate rows). Obviously initial data are the most important factor to be acting to reliability of the results irrespective of mean or method of modeling (mathematical, physical). For instance, AARI recorded many icebergs near Shtokman field at the ice expedition in Barents Sea, 2003 [Buzin I.V., 2006]. The formations had size of up to 0.2x0.4km and mass of upto 3.7 million ton (fig.1). Such their extremal spread and formation had not been noted for over hundred year term observation. And this was not considered at the exploration facilities designing on the field.

Published: December 2011

AbstractOvarian metastatic malignant melanoma is a rare form of disseminated malignant melanoma. We present a rare case of acute abdomen due to rupture of ovarian metastatic malignant melanoma seven years after removal of a primary cutaneous malignant melanoma lesion, followed by reexcision of the cicatrix and axillary dissection (Clark III, Breslow IV), one year after osteoplastic parietal craniotomy for removal of recidiv metastatic lesions, and excision of the cutaneous malignant melanoma lesion on the upper leg were performed. During laparotomy because of acute abdomen, 4 L of free liquid (blood and ascites) were evacuated. The right adnexal mass was loose tumor, size 110x75 mm, with rupture on the posterior wall and hemorrhage. Unilateral adnexectomy was performed. Pathohystologic evaluation revealed tumor cells with eosinophilic, clear cytoplasm, intracytoplasmatic melanotic pigment and a great number of mitosis.Immunohistochemical results supported positivity for protein S-100, whereas results for cytoceratin 7, cytoceratin 20, pancytoceratin, epithelial membrane antigen and HMB-45 were negative. Three months after the surgery the patient died due to disseminated cerebral melanoma. An adnexal mass and the history of previous MM should be suspected to be ovarian metastatic malignant melanoma and the patient should be seen by gynecologist at least for active treatment.

iCompose: context-aware physical user interface for application composition

Published: December 2011

Abstract
Ubiquitous computing environments advocate creating applications by plugging together various resources (mobile devices, displays, augmented everyday objects, and so on) and Web Services to support the user’s everyday activities and needs. This approach is referred to as application composition, and such applications are called composite. Due to the dynamic nature of ubiquitous environments, application composition has to be supported at runtime, so that the applications are able to adapt to the situation within the environment and other contexts. Application composition is usually performed by autonomous context-aware mechanisms that provide limited or no control for users. Still, users need to be aware of their environments and be able to control and configure applications when they are composed and executed. Towards this goal we present in this article a context-aware application composition system based on the iCompose interface for composing and controlling applications at runtime. Users compose applications by simply touching the resources in the environment with their mobile devices, while the iCompose interface provides feedback and assists users by suggesting them possible further actions. The interface relies on a rule-based reasoner and utilizes various context sources to support users dynamically, according to the situation in which they compose applications. We present a complete implementation of the system and report the results of a user evaluation study conducted with 21 participants. This study assesses the issues of control, usability, feasibility and user acceptance of the iCompose interface for context-aware application composition and the prototype as a whole.
Clustgrams: an extension to histogram densities based on the minimum description length principle
Authors: Luosto Panu , Kontkanen Petri 
Published: December 2011

Abstract
Density estimation is one of the most important problems in statistical inference and machine learning. A common approach to the problem is to use histograms, i.e., piecewise constant densities. Histograms are flexible and can adapt to any density given enough bins. However, due to the simplicity of histograms, a large number of parameters and a large sample size might be needed for learning an accurate density, especially in more complex problem instances. In this paper, we extend the histogram density estimation framework by introducing a model called clustgram, which uses arbitrary density functions as components of the density rather than just uniform components. The new model is based on finding a clustering of the sample points and determining the type of the density function for each cluster. We regard the problem of learning clustgrams as a model selection problem and use the theoretically appealing minimum description length principle for solving the task.
Three-dimensional numerical modeling of the water exchange between the Persian Gulf and the Gulf of Oman through the Strait of Hormuz

Published: December 2011

Abstract
In this study, the Navier-Stokes equations that embrace conservation equations of momentum, volume, heat and salt are solved by using a 3-D numerical model. Then, based on the values obtained, the structure and variability of the outflow/inflow between the Persian Gulf and the Gulf of Oman is investigated. The basic equations are cast in a bottom-following, sigma coordinate system which greatly simplifies the numerical solution. Conservative finite difference methods are used to discretise the mathematical model in space. The model results, which are in agreement with limited direct measurements in the Strait, show a volume transport of deep outflow and a near-surface outflow from the Persian Gulf to the Gulf of Oman through the southern part of the Strait. About 65% of total outflow occurs in the bottom layer (40 m to the bottom) and 35% in the upper layer (from the surface to 40 m deep) during the year. The annual mean of surface inflow from the Gulf of Oman to the Persian Gulf, which occurs within the northern part of the Strait is about 0.2 Sv. The net volume transport annual mean through the Strait into the Persian Gulf is about 0.03 Sv. Strong temperature and density contrasts between bottom and surface layer waters are established in spring and summer. These are more pronounced in the southern part of the Strait. In the northern part of the Strait, the salinity contrast is nearly constant, but in the southern half it varies significantly during the year.
ISMIP-HEINO experiment revisited: effect of higher-order approximation and sensitivity study
Authors: Souček Ondřej , Martinec Zdenék 
Published: December 2011

AbstractWe revisit the results of the ISMIP-HEINO benchmark by first analyzing the differences in various model outputs using a wavelet-based spectral technique. Second, the ISMIP-HEINO benchmark experiments are recomputed with a novel numerical ice-sheet model based on the SIA-I algorithm that enables both the shallow-ice and a higher-order approximation of the ice-flow equations to be performed. To assess the significance of the higher-order approximation in the ISMIP-HEINO experiment, a numerical sensitivity study for the shallow-ice approximation (SIA) simulations is also carried out. A high sensitivity of the SIA model response to surface temperature perturbations is found. We conclude that the variations in ISMIP-HEINO results are due to the differences in (1) simulated basal temperatures and (2) numerical treatment of the basal sliding condition.
Kinematic waves in polar firn stratigraphy
Authors: NG Felix , King Edward C. 
Published: December 2011

AbstractRadar studies of firn on the ice sheets have revealed complex folds on its internal layering that form from the interplay of snow accumulation and ice flow. A mathematical theory for these fold structures is presented, for the case where the radar cross section lies along the ice-flow direction and where the accumulation rate and ice-flow velocity are time-invariant. Our model, which accounts for firn densification, shows how ‘information’ (the depth and slope of isochrones) propagates on the radargram to govern its layer undulations. This leads us to discover universal rules behind the pattern of layer slopes on a distance–age domain and understand why the loci of layer-fold hinges curve, emerge and combine on the radargram to form closed loops that delineate areas of rising and plunging isochrones. We also develop a way of retrieving the accumulation rate distribution and layer ages from steady isochrone patterns. Analysis of a radargram from the onset zone of Bindschadler Ice Stream, West Antarctica, indicates that ice flow and accumulation rates have been steady there for the past ∼400 years, and that spatial anomalies in the latter are coupled to surface topography induced by ice flow over the undulating ice-stream bed. The theory provides new concepts for the morphological interpretation of radargrams.
