Improved Forecasting of Extreme Monthly Reservoir Inflow Using an Analogue-Based Forecasting Method: A Case Study of the Sirikit Dam in Thailand
Authors: Amnatsan Somchit , Yoshikawa Sayaka , Kanae Shinjiro
Published: November 2018

Reservoir inflow forecasting is crucial for appropriate reservoir management, especially in the flood season. Forecasting for this season must be sufficiently accurate and timely to allow dam managers to release water gradually for flood control in downstream areas. Recently, several models and methodologies have been developed and applied for inflow forecasting, with good results. Nevertheless, most were reported to have weaknesses in capturing the peak flow, especially rare extreme flows. In this study, an analogue-based forecasting method, designated the variation analogue method (VAM), was developed to overcome this weakness. This method, the wavelet artificial neural network (WANN) model, and the weighted mean analogue method (WMAM) were used to forecast the monthly reservoir inflow of the Sirikit Dam, located in the Nan River Basin, one of the eight sub-basins of the Chao Phraya River Basin in Thailand. It is one of four major dams in the Chao Phraya Basin, with a maximum storage of 10.64 km3, which supplies water to 22 provinces in this basin, covering an irrigation area of 1,513,465 hectares. Due to the huge extreme monthly inflow in August, with inflow of more than 3 km3 in 1985 and 2011, monthly or longer lead time inflow forecasting is needed for proper water and flood control management of this dam. The results of forecasting indicate that the WANN model provided good forecasting for whole-year forecasting including both low-flow and high-flow patterns, while the WMAM model provided only satisfactory results. The VAM showed the best forecasting performance and captured the extreme inflow of the Sirikit Dam well. For the high-flow period (July–September), the WANN model provided only satisfactory results, while those of the WMAM were markedly poorer than for the whole year. The VAM showed the best capture of flow in this period, especially for extreme flow conditions that the WANN and WMAM models could not capture.
A Global Optimization-Based Method for the Prediction of Water Inrush Hazard from Mining Floor

Published: November 2018

Water inrush hazards can be effectively reduced by a reasonable and accurate soft-measuring method on the water inrush quantity from the mine floor. This is quite important for safe mining. However, there is a highly nonlinear relationship between the water outburst from coal seam floors and geological structure, hydrogeology, aquifer, water pressure, water-resisting strata, mining damage, fault and other factors. Therefore, it is difficult to establish a suitable model by traditional methods to forecast the water inrush quantity from the mine floor. Modeling methods developed in other fields can provide adequate models for rock behavior on water inrush. In this study, a new forecast system, which is based on a hybrid genetic algorithm (GA) with the support vector machine (SVM) algorithm, a model structure and the related parameters are proposed simultaneously on water inrush prediction. With the advantages of powerful global optimization functions, implicit parallelism and high stability of the GA, the penalty coefficient, insensitivity coefficient and kernel function parameter of the SVM model are determined as approximately optimal automatically in the spatial dimension. All of these characteristics greatly improve the accuracy and usable range of the SVM model. Testing results show that GA has a useful ability in finding optimal parameters of a SVM model. The performance of the GA optimized SVM (GA-SVM) is superior to the SVM model. The GA-SVM enables the prediction of water inrush and provides a promising solution to the predictive problem for relevant industries.

Phosphates hydrothermaux de basse température et kaolinisation : la gorceixite du massif des Colettes (Allier) et les minéraux associés (hinsdalite)
Authors: Nicolas Jean , Rosen Andrée de
Published: November 2018

Quelques précisions sont tout d'abord apportées à la connaissance de la gorceixite et de la hinsdalite découvertes dans le Massif des Colettes (Allier). Les conditions de genèse de ces deux minéraux et de certaines autres espèces qui leur sont associées dans ce massif sont ensuite examinées. Ces minéraux se sont formés après la kaolinisation hydrothermale, à partir de solutions résiduelles enrichies en P et Al, qui avaient dissous de la barytine, de la fluorine et quelques sulfures. Les conditions physico-chimiques étaient celles d'une zone d'oxydation superficielle.

Les faibles solubilités trouvées au cours des essais d'altération de ces trois minéraux ont conduit à étudier la stabilité de leurs dispersions aqueuses. Celles-ci se comportent comme des hydrosols électro˗négatifs et sont sensibles à l'action des sels dissous. La floculation est d'autant plus rapide que la valence des cations est plus élevée (règle de Schulze˗Hardy). Elle est de plus nettement accélérée par des substances macromoléculaires présentes dans la matière organique de la tourbe.
On the possible mechanism of formation of euhedral crystals in metasomatic processes
Authors: Beus Alexei
Published: November 2018

There is a group of minerals which in most cases are found in euhedral crystals regardless of where they were formed : in a free space of some cavity, or being embedded in a hard rock. This group of minerals mainly includes compounds of amphoteric rare metals (Be, Ta, Nb, Zr), rare earth and B. The above phenomenon could be explained by geochemical peculiarities of transportation of these elements in hydrothermal solutions and crystallization of the respective minerals during metasomatism. Under conditions of a comparatively high total activity of acids in the presence of significant amounts of strong alkalic ions (K⁺, Na⁺) the mobile acidocomplex compounds of listed amphoteric elements are the most probable forms of their transportation in hydrothermal solutions. Désintégration of the mobile acidocomplexes which is followed by formation of the respective minerals is always accompanied by the release of strong acidic anions which takes place at the surface of the crystal in formation. Thus, the metasomatically growing crystal is constantly surrounded by a thin liquid cover of active acidic solution which intensely dissolves the host rock, providing the crystal with conditions of "free growth" in the solid environment.

Characterization of iron distribution in various pumice grades and in the derived zeolites
Authors: Burriesci Nicola , Giordano Nicola , Cariati Franco , Petrera Michele , Bart Jan C. J.
Published: November 2018

On a examiné de la pierre ponce rhyolitique provenant de coulées géologiques très différentes et d'une éruption volcanique sous-marine récente au moyen de techniques d'analyses chimiques, de diffraction de rayons X, de spectroscopie Mössbauer du 57Fe et de spectroscopie paramagnétique électronique (RPE) dans le but de déterminer la distribution et la configuration structurale du fer.

On a procédé à l'interprétation des spectres Mössbauer à 77 K sur la base de quatre spectres partiels (sous-spectres) qui sont typiques de deux sites octaédriques à spin élevé de Fe2+ à différents degrés de distortion et de deux sites à spin élevé de Fe3+ à coordination octaédrique et tétraédrique. Les sites du fer sont semblables dans toutes les variétés de pierre ponce ; cependant les occupations relatives varient. L'analyse statistique des paramètres spectraux (splitting quadrupolaire, déplacements d'isomérie et distribution des cations) permet la classification des pierres ponces selon l'origine et le traitement physico-chimique.

Si l'on considère à part la pierre ponce de Navajo qui est caractérisée par une valeur réelle extrêmement élevée de g due aux ions isolés de Fe3+ dans d'intenses champs cristallins de basse symétrie, les autres échantillons de pierre ponce présentent essentiellement cinq spectres différents de RPE avec des bandes de résonance étroites de contribution variable aux valeurs de g ≃ 4,3 (symétrie C2v de Fe3+ isolé à spin élevé) et de g ≃ 2,0 (Fe3+ coordonné tétraédriquement ou octaédriquement de symétrie Td, Oh ou C3v) et avec un signal peu prononcé à g ≃ 2,3 (dû partiellement aux oxydes de fer).

Cinq échantillons de pierre ponce, choisis sur la base de l'analyse des agglomérats, ont été transformés en zéolite en solution alcaline dans des conditions expérimentales identiques. La sélectivité des zéolites est en corrélation avec le rapport SiO2/Al2O3 et avec la quantité de Fe2+ correspondante.
Le magmatisme alcalin potassique de l'aire volcanique des Virunga (Rift occidental de l'Afrique de l'Est). Une approche statistique dans la recherche des filiations magmatiques et des mécanismes de différenciation
Authors: Pouclet André , Ménot René-Pierre , Piboule Michel
Published: November 2018

The lavas of the Virunga area are divided into four main series : K-basanitic, leucitic, K-nephelinitic and melilitic ones. The assumption of an initial and common magma genesis of K-basanitic type can be considered. The mafic lavas of the four series undergo a comparable evolution through Fe-Mg crystals fractionation. Within the intermediate, and then within the acid lavas, different evolution trends are obvious and depend on the following various processes : fractional crystallization of feldspars, of micas and/or oxides ; crustal contamination and pneumatolytic differentiation. The major element geochemical study, using multivariate statistical methods, allows us to decide between and to give some new precisions about these distinct hypothetical processes ; but no clear evidence of these mechanisms can be given. So, accurate petrological studies remain necessary.

LIFECYCLE PERFORMANCE MEASUREMENT OF PUBLIC-PRIVATE PARTNERSHIPS: A CASE STUDY IN CHINA’S WATER SECTOR
Authors: Bao Fengyu , Martek Igor , Chen Chuan , Chan Albert P. C. , Yu Yao
Published: November 2018

Numerous public-private partnership (PPP) infrastructure projects have been operating in China after nearly 30 years of development. Surprisingly, few lessons and experiences have been drawn from these existing cases, thereby creating an urgent demand for a comprehensive evaluation of their performance. Thus, this paper presents a timely contribution to the assessment of a representative PPP project in China’s water sector, the Chengdu No. 6 Water Plant B Project, from a lifecycle perspective. Through a triangulation method, the project is generally deemed a success providing instructive lessons on the future evolutionary development of PPPs in China despite several imperfections caused by particular historical factors. Moreover, this paper advances the performance measurement of PPPs offering empirical insights to promote the efficacy of conceptual performance measurement frameworks. The outcomes of this research are especially valuable to the current Chinese PPP community where huge opportunities and challenges simultaneously exist.
Numerical Analysis of Nonlocal Convection—Comparison with Three-dimensional Numerical Simulations of Efficient Turbulent Convection
Authors: Cai Tao
Published: November 2018

We compare 1D nonlocal turbulent convection models with 3D hydrodynamic numerical simulations. We study the validity of closure models and turbulent coefficients by varying the Prandtl number, the Péclet number, and the depth of the convection zone. Four closure models of the fourth-order moments are evaluated with the 3D simulation data. The performance of the closure models varies among different cases and different fourth-order moments. We solve the dynamic equations of moments together with equations of the thermal structure. Unfortunately, we cannot obtain steady-state solutions when these closure models of fourth-order moments are adopted. In contrast, the numerical solutions of the down-gradient approximations of the third-order moments are robust. We calibrate the coefficients of the 1D down-gradient model from the 3D simulation data. The calibrated coefficients are more robust in cases of deep convection zones. Finally, we have compared the 1D steady-state solutions with the 3D simulation results. The 1D model has captured many features that appear in the 3D simulations: (1) ∇ − ∇
a
has a U-shape with a minimum value at the lower part of the convection zone; (2) there exists a bump for ∇ − ∇
a
near the top of the convection zone when the Péclet number is large; and (3) the temperature gradient can be sub-adiabatic due to the nonlocal effect. However, aside from these similarities, the prediction on the kinetic energy flux is unsatisfactory.
X-Ray Spectral Properties of Seyfert I Galaxy LEDA 168563
Authors: Liebmann Andrew C. , Fabian Andrew C. , Tsuruta Sachiko , Haba Yoshito , Kunieda Hideyo
Published: November 2018

Interesting among possible mechanisms responsible for X-ray emission from active galactic nuclei (AGNs) is ionized relativistic reflection (IRR). Since it arises close to the central black hole it can test strong gravity. Its characteristic features include a high energy Compton hump, a broad Fe Kα line, and a soft excess. Therefore, using the Swift-Burst Alert Telescope (BAT) catalog we looked for hard X-ray selected AGNs that may exhibit at least one of these characteristic features. Among the possibly interesting targets found is Seyfert I Galaxy LEDA 168563. We obtained a broadband 100 ks Suzaku observation of this source, and careful analysis of the data was carried out. The results support the presence of these IRR distinct features. Moreover, the comparison of the earlier combined XMM-Newton and Swift-BAT and more recent Suzaku data showed interesting long-term spectral variability. The soft excess decreased while higher energy features relatively increased and the power-law component became flatter—the behavior predicted by the IRR model.

Published: November 2018

We have carried out an extensive X-ray spectral analysis of a sample of galaxies exhibiting molecular outflows (MOX sample) to characterize the X-ray properties and investigate the effect of active galactic nuclei (AGNs) on the dynamical properties of the molecular outflows (MOs). We find that the X-ray bolometric correction (L
2–10 keV/L
AGN) of these sources ranges from ∼10−4.5 to 10−0.5, with ∼70% of the sources below 10−2, implying a weak X-ray emission relative to the AGN bolometric luminosity (L
AGN). However, the upper limit on the 2–10 keV luminosity (

) obtained from 12 μm flux, following the correlation derived by Asmus et al., is ∼0.5–3 orders of magnitude larger than the L
2–10 keV values estimated using X-ray spectroscopy, implying a possibility that the MOX sources host normal AGNs (not X-ray weak), and their X-ray spectra are extremely obscured. We find that both L
2–10 keV and L
AGN correlate strongly with the MO velocity and the mass outflow rates (

), implying that the central AGN plays an important role in driving these massive outflows. However, we also find statistically significant positive correlations between the starburst emission and MO mass outflow rate,

versus

, and L
0.6–2keV versus

, which implies that starbursts can generate and drive the MOs. The correlations of MO velocity and

with AGN luminosities are found to be stronger compared to those with the starburst luminosities. We conclude that both starbursts and AGNs play a crucial role in driving the large-scale MO.
Harmonic Summing Improves Pulsar Detection Sensitivity: A Probability Analysis
Authors: Yu Meng
Published: November 2018

The practical application of the harmonic summing technique in the power-spectrum analysis for searching pulsars has exhibited the technique’s effectiveness. In this paper, theoretical verification of harmonic summing considering power’s noise-signal probability distribution is given. With the top-hat and the modified von Mises pulse profile models, contours along which spectra total power is expected to exceed the 3σ detection threshold with 0.999 confidence corresponding to m = 1, 2, 4, 8, 16, or 32 harmonics summed are given with respect to the mean pulse amplitude and the pulse duty cycle. Optimized numbers of harmonics summed relative to the duty cycles are given. The routine presented builds a theoretical estimate of the minimum detectable mean flux density, i.e., sensitivity, under the power-spectrum searching method.
The Connection between Starspots and Flares on Main-sequence Kepler Stars
Authors: Roettenbacher Rachael M. , Vida Krisztián
Published: November 2018

Starspots and flares are indicators of stellar magnetic activity and can both be studied in greater detail by utilizing the long-term, space-based archive of the Kepler satellite. Here, we aim to investigate a subset of the Kepler archive to reveal a connection between the starspots and the stellar flares, in order to provide insight into the overall stellar magnetic field. We use the flare-finding algorithm FLATW’RM in conjunction with a new suite of algorithms that aim to locate the local minima caused by starspot groups. We compare the phase difference between the time of maximum flux of a flare and the time of minimum stellar flux due to a starspot group. The strongest flares do not appear to be correlated to the largest starspot group present, but are also not uniformly distributed in phase with respect to the starspot group. The weaker flares, however, do show an increased occurrence close to the starspot groups.
Perspectives on Rosa Luxemburg 2
Authors: Parry Benita
Published: November 2018

In this exchange, Benita Parry reinstates the significance of Luxemburg as a Marxist thinker and activist, whose kind of political commitment cannot be detached from the revolutionary tradition of socialism. Parry's compelling reflections address Luxemburg's relevance to defining vital
questions in Marxism, especially the centrality of class struggle, the Party, spontaneity, imperialism, combined and uneven development, and the accumulation of capital in a neoliberal age. Parry shows how Luxemburg's vision is necessarily a systemic, dialectical and materialist one, in a
way that could inspire current generations to keep the socialist tradition alive. In the concluding sections, Parry also explores the significance of Luxemburg to rethinking postcolonial studies and the Jewish question today.
Neoliberal Capitalism and Its Crises In Europe: Towards a Luxemburgian Interpretation
Authors: Schmidt Ingo
Published: November 2018

This article recapitulates Rosa Luxemburg's considerations on the capitalist penetration of non-capitalist economies as a condition for capital accumulation, as well as her arguments about the limits of social reform and the shortcomings of claims for national self-determination. The
theoretical tools Luxemburg developed around these issues are then used to analyse the rise, consolidation and crisis of neoliberal capitalism in Europe. This analysis stresses the reintegration of previously communist countries into the capitalist world system and the China boom as drivers
of this neoliberal wave of accumulation. It concludes with pointing at the economic limits of this wave and at emerging left and right alternatives to neoliberal capitalism

Published: November 2018

La loi relative à la sécurisation de l’emploi (LSE) de 2013 a créé une consultation obligatoire sur la stratégie d’entreprise. Elle formalise et renforce ainsi l’implication des institutions représentatives du personnel (IRP). Cette nouvelle consultation soulève un intérêt mitigé chez les élus et fait face à des réticences des directions à partager des informations stratégiques. Celles-ci sont souvent parcellaires et les droits d’accès des élus restreints selon les niveaux de consultation. C’est la notion-même de stratégie qui apparaît disputée. En outre, la recherche d’information et d’un interlocuteur pertinent pour discuter de la stratégie renforce un mouvement de centralisation des IRP au sein des entreprises au détriment des comités d’établissement. Ce renforcement de la centralisation entraîne une recomposition des différentes IRP : à l’établissement, le comité d’hygiène, de sécurité et des conditions de travail (CHSCT), à l’entreprise, le comité central d’entreprise (CCE). Cette recomposition interroge la mise en place des futurs comités sociaux et économiques (CSE).
L’expert auprès des comités d’entreprise, acteur oublié des relations professionnelles

Published: November 2018

Depuis les années 1980, le rôle des experts et expertes auprès des comités d’entreprise (CE) dans les relations professionnelles françaises s’est accru. Cet article propose de mettre en lumière les évolutions de leur rôle à l’occasion de changements législatifs récents. En effet, la loi du 14 juin 2013 relative à la sécurisation de l’emploi (LSE) a créé de nouvelles missions pour les expertes et les experts auprès des CE et redéfini la façon dont ils interviennent dans le cadre des missions existantes. Comment expertes et experts intègrent-ils ces nouvelles mesures dans leurs pratiques professionnelles ? Qu’est-ce que cela révèle des rapports avec les représentants et représentantes des salarié·es ? L’article répond à ces questions à partir d’une analyse secondaire d’entretiens menés dans le cadre d’une enquête sur les CE. L’enquête illustre la façon dont les nouvelles missions sollicitent une variété de registres d’action des experts. Un point commun est qu’ils tendent à s’étendre à des champs d’action que l’on pourrait penser comme relevant du domaine syndical.
L’« Orient sémite » et les aléas de la puissance masculine
Authors: Schneider Monique
Published: November 2018

Accompagnant Freud dans son mouvement vers « l’Orient sémite », Lacan met l’accent, non sur l’avoir masculin, mais sur l’expérience de détumescence, dans ses rapports avec les héritages judaïque et égyptien. L’attention à l’instrument présent dans le cérémonial juif, le chofar, invite à souligner l’importance du « signifiant vocalisé », entrant par l’oreille et conduisant à un « résonateur de type tuyau ». La remise en question de la « puissance » masculine rencontre la démarche d’Apulée dans L’Âne d’or .
Sujet de l’inconscient ?
Authors: Ogilvie Bertrand
Published: November 2018

Accentuant le parti pris freudien d’un rejet de toute normativité thérapeutique, Lacan construit une conception du sujet de l’inconscient dont le but est de faire de la cure un lieu de reconfiguration psychique pour un sujet auquel il dénie toute maîtrise sur le sens de son existence. C’est l’insistance sur la domination du langage dans la vie humaine, milieu d’existence et non instrument de communication, qui fait apparaître la profonde dépendance du sujet et le lien structurel entre le sexe et la mort. La précision clinique des entrelacs de cette articulation permet à ce qui pourrait n’être qu’une nouvelle anthropologie de produire des effets pratiques de déplacements continus.
Oui, une référence à Lacan peut être utile à notre technique analytique
Authors: Joubert Martin
Published: November 2018

Les propositions techniques de Lacan se situent le plus souvent dans le prolongement des écrits techniques de Freud. Son originalité tient à sa fidélité à ces fondamentaux freudiens que sont le langage mis au centre du drame de la cure et son corollaire, la nécessaire asymétrie du dispositif qui la rend possible. L’inquiétante ambiguïté dans laquelle le patient vit son exposition au transfert rend compte de l’importance de la neutralité/ Indifferenz comme position interne fondamentale de l’analyste. En revanche, l’artifice technique de la scansion risque de pousser l’analyste à faire l’économie d’un travail du contre-transfert, pourtant indispensable à pouvoir figurer et mettre en mots certains moments de profonde régression vécus en séance. Ces différents aspects des apports de Lacan à la technique seront confrontés dans cinq vignettes cliniques.

The Truth About Obesity, Exercise, and Nutrition
Authors: Dawson Rachel S.
Published: November 2018

There is a plethora of misinformation regarding obesity, diet, and exercise due to lack of supporting evidence on these topics. There are myths and facts about what exactly encompasses a healthy lifestyle that interfere with the ability to lose weight and stay healthy. These include topics such as the effects of small sustained increases in energy intake or expenditure, establishment of realistic goals, rapid weight loss, readiness for weight loss, physical activity, breast-feeding as well as the effects of eating breakfast daily, early childhood experiences, eating fruits and vegetables, weight that cycles up and down, snacking, and the environment. There are evidence-based approaches that can help guide people in their pursuit of a healthy lifestyle, weight loss, and physical activity. Pediatricians and health care providers should be aware of these approaches when counseling patients on a healthy lifestyle.

Wilson's Disease: A Review for the General Pediatrician
Authors: Capone Kristin , Azzam Ruba K.
Published: November 2018

Wilson's disease, also known as hepatolenticular degeneration, is an autosomal recessive genetic disorder due to a mutation of the ATP7B gene resulting in impaired hepatic copper excretion and copper accumulation in various tissues. It is associated with the classic triad of cirrhosis, neurological manifestations, and the ocular finding of Kayser-Fleischer rings; however, the clinical presentation can vary greatly from incidental findings of abnormal liver enzymes to acute liver failure necessitating liver transplant. Pediatric patients may present with subtle findings including asymptomatic hepatomegaly, transaminitis, changes in behavior, movement disorders, or school failure. The general pediatrician may be the first to recognize these symptoms and should consider Wilson's disease in their differential diagnosis. Wilson's disease can be managed with lifelong chelation or zinc therapy in patients who present early in the disease; therefore, pediatricians should have a low threshold for referral to a pediatric hepatologist for further evaluation when it is suspected.

Estas localidades se sitúan en regiones con bioclima árido y semiárido y escasa cobertura vegetal. Se aportan datos sobre el hábitat, caracteres diagnósticos y variabilidad morfológica de la especie.
L’inefficience des partenariats public-privé appliqués aux prisons françaises
Authors: Rigamonti Éric , Leroux Isabelle
Published: November 2018

Avec le groupage des tâches et la propriété privée de l’équipement, les partenariats public-privé (PPP) devraient être plus efficients que la commande publique traditionnelle (CPT). Toutefois, certains PPP ne produisent pas ce supplément d’efficience. C’est notamment le cas pour les nouvelles prisons françaises. Dans le prolongement de la littérature relative aux PPP, nous étudions le cas de la construction de ces prisons afin d’expliciter les raisons de cette inefficience. Ainsi, nous mettons en exergue comment, dans un environnement concurrentiel peu favorable, le passage de la CPT au PPP peut conduire à la formation d’un oligopole en capacité d’extraire une rente. Nous montrons également que le consortium signataire du contrat de partenariat est imparfait et ne génère pas le système d’incitation attendu.

Nowadays, social media and social networks are increasingly used in business as they have drastically changed the way the community works, communicates, collaborates, socialises, creates content and shares knowledge and ideas. However, in particular, IT professionals and practitioners need to be aware of online security and privacy issues and the potential negative impact that they may cause on different aspects of business, such as online breaches or information theft. The use of social media inevitably leads to disclosure of personal information, with the use of open-source intelligence (OSINT) and other similar techniques. Hence, the aim of this article is twofold, namely first to show results of a survey towards future Greek IT practitioners regarding awareness and viewpoints of social media users concerning security and privacy on social media. More specifically the study was based on responses and viewpoints of 178 Greek electrical engineering and IT students to an online questionnaire. Secondly, the aim is also to show how easily a potential malicious user can anonymously track and retrieve sensitive personal information in an automated and undetectable way from popular social media platforms by using publicly available information, resources, and tools. The results of the survey show that most of the respondents are aware of the privacy settings of the social media platforms they use. However, they consider that they should be more careful concerning personal data and whom they add as friends or followers and they do not feel comfortable with the fact that a stranger might be able to access their personal information through their publications on social media platforms.The case study indicates that it is possible for malicious users to acquire sensitive personal data (e.g. user's location via tweets and instas from smartphones). In addition, the ability to map activity could allow malicious users to track the activities of unsuspected users and predict their future locations.
Automated Context Formalization for Context-aware Specification Approach

Published: November 2018

Requirement specification is a key element in model-checking verification. The context-aware approach is an effective technique for automating the specification of requirement considering specific environmental conditions. In most of existing approaches, there is no support of this crucial task and are mainly based on the considerable efforts and expertise of engineers. A domain-specific language, called CDL, has been proposed to facilitate the specification of requirement by formalizing contexts. However, the feedback has shown that manually writing CDL is hard, error prone and difficult to grasp on complex systems. In this article, the authors propose an approach to automatically generate CDL models using (IODs) elaborated through transformation chains from textual use cases. They offer an intermediate formalism between informal use cases scenarios and CDL models allowing to engineers to manipulate with familiar artifacts. Thanks to such high-level formalism, the gap between informal and formal requirements is reduced; consequently, the requirement specification is facilitated.

Authors: Koole Marguerite , Lewis Kevin wâsakâyâsiw
Published: November 2018

In this article, the authors explore how mobile learning can complement the Certificate of Indigenous Languages program at the University of Saskatchewan in Western Canada. Through the FRAME model analysis, the authors extract salient cultural, pedagogical, environmental, and technological characteristics that should be considered in the development of mobile learning tools and approaches for Cree language teachers. It is hoped that this article will stimulate a dialogue amongst designers and Indigenous groups regarding language sustainability through mobile learning. The article concludes with key findings: the need to follow protocols, to establish good relationships, and to design for areas of low/no bandwidth. Finally, the examination of current Indigenous language learning methods provides ideas for the development of much needed “apps” appropriate for Cree learners and teachers.

Published: November 2018

This article describes how in recent years, the multimedia recording capabilities of mobile devices have been used increasingly to create a more active, learner-centred educational experience. Despite the proven value of student-generated multimedia projects, there are still gaps in our understanding of how students learn during them. This article reports on a project in which first-year information technology students interviewed IT professionals in their workplace and video-recorded the interview to enable sharing with their peers. In order to understand the statistically significant increases found in students' learning, student diaries and reflections were analyzed qualitatively. Factors found to contribute to learning included: the iterative nature of student activities; the multiple, evolving representations of knowledge as students proceeded through the project; the importance of the workplace context in engaging students and enhancing learning; the affordance of mobile technology for capturing and sharing this context; and the collaborative and metacognitive processes fostered by the project.
Literacies and Learning in Motion
Authors: Frawley Jessica Katherine , Dyson Laurel Evelyn
Published: November 2018

Mobile and participatory cultures have led to widespread change in the way we communicate; emphasizing user generated content and digital multimedia. In this environment, informal learning may occur through digital and networked activities, with literacy no longer limited to alphabetic and character-based texts. This article explores adult learners' new literacies within the context of a digital mobile storytelling project. A qualitative approach is used to explore the artifacts and practices of nine adult participants who comprise the study. Participants created a range of fiction, non-fiction, poetry and diary-style content in a variety of modes and media. Outcomes from content analysis, interview and survey methods depict mobile digital literacies as characteristically situated, experiential and multimodal. The mobile and participatory nature of this project was catalytic to participants' imaginative re-interpretation of the world around them as sources for meaning making and transformation. This paper contributes a case example of mobile learning with adults in a community setting.

In this study, the spatial distribution of road accidents involving wandering dogs on urban roads of Naples was assessed using kernel density estimation (KDE). The study included 423 dogs victim of road collisions in the period 2012-2015 collected from the medical records of Interdepartmental Centre of Veterinary Radiology, of Pathological Anatomy Service, of Veterinary Teaching Hospital, “Federico II” University of Naples, and of Veterinary Hospital Attendance of the Local Public Health Unit Napoli1. There were a significant prevalence of young male dogs and the KDE demonstrated the presence of five hotspots in five city neighbourhoods. All areas with the highest KDE were found to be peripheral zones in which wide green areas, uncultivated or cultivated, merged with built areas and crossed by large straight roads with a lot of intersections. Wandering dogs as other animals represent a mounting problem on urban roads in Italy, despite of the effort to reduce these populations. Better knowledge of this phenomenon is important with reference to taking countermeasures and improve road safety. It is also important with reference to One Health and the Decade of Action for Road Safety 2011- 2020 of the United Nations.

Cardiovascular diseases (CVDs) are the leading cause of death globally and the number one cause of death globally. Over 75% of CVD deaths take place in low- and middle-income countries. Hence, comprehensive information about the spatio-temporal distribution of mortality due to cardio vascular disease is of interest. We fitted different spatio-temporal models within Bayesian hierarchical framework allowing different space-time interaction for mortality mapping with integrated nested Laplace approximations to analyze mortality data extracted from the health and demographic surveillance system in Kersa District in Hararege, Oromia Region, Ethiopia. The result indicates that non-parametric time trends models perform better than linear models. Among proposed models, one with non-parametric trend, type II interaction and second order random walk but without unstructured time effect was found to perform best according to our experience and. simulation study. An application based on real data revealed that, mortality due to CVD increased during the study period, while administrative regions in northern and south-eastern part of the study area showed a significantly elevated risk. The study highlighted distinct spatiotemporal clusters of mortality due to CVD within the study area. The study is a preliminary assessment step in prioritizing areas for further and more comprehensive research raising questions to be addressed by detailed investigation. Underlying contributing factors need to be identified and accurately quantified.

The present study was planned to characterize the microclimate experienced by Aedes larvae in different breeding habitats by determining the temperature variations in water kept in containers during different months under natural conditions. The study was conducted in three municipal zones of Delhi. In each site, four types of container material (plastic, cement, iron and ceramic) were chosen for recording the water temperature in the containers. Daily air and water temperatures (mean, maximum and minimum values) recorded by HOBO and Tidbit data loggers, respectively, were compared using analysis of variance and Tukey’s honest significant difference (HSD) tests. Mean monthly temperature of water varied from 16.9 to 33.0 °C in tin containers, 17.3 to 35.6°C in plastic containers, 14.3 to 28.5°C in ceramic pots, 23.3 to 30.4°C in cemented underground tanks (UGT) and 15.8 to 35.1°C in cemented overhead tanks (OHTs). Corresponding values for the air temperature ranged from 17.7 to 36.1°C. The difference between temperature of water in the containers and air temperature was highest for ceramic pots. Daily mean, maximum and minimum temperatures recorded by different data loggers differed significantly (P<0.05). When Tukey HSD test was applied for data analysis, the daily mean air temperature differed significantly from the water temperature in tin and ceramic pots as well as cemented OHTs. The temperature of water in the different breeding habitats investigated was lower than the air temperature. Moreover, actual air temperature as recorded by HOBO was higher than the temperature recorded by local weather stations. Considering the ongoing climate change, cemented UGT and earthen pots may be more productive breeding habitats for the Aedes mosquito in the near future, while plastic and cemented OHTs might no longer be suitable for Aedes breeding.

We studied the geospatial distribution of health facilities in Belgrade, the capital of the Republic of Serbia, in relation to the public transport system. Analyses in this research were based on advanced geographical information systems using numerical methods. We calculated accessibility to health centres as based on public transport properties accounting for the movement of citizens, as well as patients, through the city. Based on results, the city of Belgrade has a moderate connectivity. Public health centres and a group of other health centres in the central-east part of the city have a better connectivity. Also, in this paper we estimated that the average time necessary to reach health facilities on foot is 100 minutes and by public transport vehicles such as buses, trams and trolleys is 42 minutes.

Analytical calculation of the fault-plane problem
Authors: Knopoff L
Published: November 2018

Machine calculation of the solution to the fault-plane problem is possible, if an analytical formulation of the problem can be made. An analytical formulation is made in terms of the probability that a station report the correct sign of first motion in the
presence of disturbing influences such as background noise. The location of the orthogonal planes depends upon the maximization of a certain probability function. The probability function is simplified if it is assumed that the ground motion noise level is constant at ail stations. The maximization
is then made with respect to four variables: the three independent angular variables describing the orientation of the two orthogonal planes and the noise. An example of the machine calculation of the maximization is given for the Alaska earthquake of July 10, 1958; the machine solution is compared
with the solution obtained by visual means.
