POINTO - A LOW COST SOLUTION TO POINT CLOUD PROCESSING
Authors: Houshiar H. , Winkler S.
Published: November 2017

Abstract. With advance in technology access to data especially 3D point cloud data becomes more and more an everyday task. 3D point clouds are usually captured with very expensive tools such as 3D laser scanners or very time consuming methods such as photogrammetry. Most of the available softwares for 3D point cloud processing are designed for experts and specialists in this field and are usually very large software packages containing variety of methods and tools. This results in softwares that are usually very expensive to acquire and also very difficult to use. Difficulty of use is caused by complicated user interfaces that is required to accommodate a large list of features. The aim of these complex softwares is to provide a powerful tool for a specific group of specialist. However they are not necessary required by the majority of the up coming average users of point clouds. In addition to complexity and high costs of these softwares they generally rely on expensive and modern hardware and only compatible with one specific operating system. Many point cloud customers are not point cloud processing experts or willing to spend the high acquisition costs of these expensive softwares and hardwares. In this paper we introduce a solution for low cost point cloud processing. Our approach is designed to accommodate the needs of the average point cloud user. To reduce the cost and complexity of software our approach focuses on one functionality at a time in contrast with most available softwares and tools that aim to solve as many problems as possible at the same time. Our simple and user oriented design improve the user experience and empower us to optimize our methods for creation of an efficient software. In this paper we introduce Pointo family as a series of connected softwares to provide easy to use tools with simple design for different point cloud processing requirements. PointoVIEWER and PointoCAD are introduced as the first components of the Pointo family to provide a fast and efficient visualization with the ability to add annotation and documentation to the point clouds.

Published: November 2017

Abstract. At present, digital documentation recorded in the form of raster or vector files is the obligatory way of inventorying historical objects. Today, photogrammetry is becoming more and more popular and is becoming the standard of documentation in many projects involving the recording of all possible spatial data on landscape, architecture, or even single objects. Low-cost sensors allow for the creation of reliable and accurate three-dimensional models of investigated objects. This paper presents the results of a comparison between the outcomes obtained when using three sources of image: low-cost Xiaomi cameras, a full-frame camera (Canon 5D Mark II) and middle-frame camera (Hasselblad-Hd4). In order to check how the results obtained from the two sensors differ the following parameters were analysed: the accuracy of the orientation of the ground level photos on the control and check points, the distribution of appointed distortion in the self-calibration process, the flatness of the walls, the discrepancies between point clouds from the low-cost cameras and references data. The results presented below are a result of co-operation of researchers from three institutions: the Systems Research Institute PAS, The Department of Geodesy and Cartography at the Warsaw University of Technology and the National Museum in Warsaw.

Published: November 2017

Abstract. This paper considers Leica backpack and photogrammetric surveys of a mediaeval bastion in Padua, Italy. Furhtermore, terrestrial laser scanning (TLS) survey is considered in order to provide a state of the art reconstruction of the bastion. Despite control points are typically used to avoid deformations in photogrammetric surveys and ensure correct scaling of the reconstruction, in this paper a different approach is considered: this work is part of a project aiming at the development of a system exploiting ultra-wide band (UWB) devices to provide correct scaling of the reconstruction. In particular, low cost Pozyx UWB devices are used to estimate camera positions during image acquisitions. Then, in order to obtain a metric reconstruction, scale factor in the photogrammetric survey is estimated by comparing camera positions obtained from UWB measurements with those obtained from photogrammetric reconstruction. Compared with the TLS survey, the considered photogrammetric model of the bastion results in a RMSE of 21.9cm, average error 13.4cm, and standard deviation 13.5cm. Excluding the final part of the bastion left wing, where the presence of several poles make reconstruction more difficult, (RMSE) fitting error is 17.3cm, average error 11.5cm, and standard deviation 9.5cm. Instead, comparison of Leica backpack and TLS surveys leads to an average error of 4.7cm and standard deviation 0.6cm (4.2cm and 0.3cm, respectively, by excluding the final part of the left wing).

This article deepens the subject of photo-modelling applied to architecture, on a medium and large scale and it shows all the possibilities to apply the last technologies of augmented reality and virtual reality to the historical and architectural contest of Havana City in Cuba. The context was quite unsuitable to our project because of different and complex reasons. The need to minimize the size of the tools, their weight and cost. Minimize the time of survey and photographic shot on site. To face the difficulties given by the continuing presence of a chaotic influx of people disturbing the work. Not least the difficulty of having a limited number of daily hours available to carry out photographic shots that requires special lighting conditions. This article describes the necessary steps to obtain a 3D dimensional textured model from reality through a photographic set.
THE PHOTOGRAMMETRIC SURVEY METHODOLOGIES APPLIED TO LOW COST
3D VIRTUAL EXPLORATION IN MULTIDISCIPLINARY FIELD
Authors: Palestini C. , Basso A.
Published: November 2017

Abstract. In recent years, an increase in international investment in hardware and software technology to support programs that adopt algorithms for photomodeling or data management from laser scanners significantly reduced the costs of operations in support of Augmented Reality and Virtual Reality, designed to generate real-time explorable digital environments integrated to virtual stereoscopic headset. The research analyzes transversal methodologies related to the acquisition of these technologies in order to intervene directly on the phenomenon of acquiring the current VR tools within a specific workflow, in light of any issues related to the intensive use of such devices , outlining a quick overview of the possible "virtual migration" phenomenon, assuming a possible integration with the new internet hyper-speed systems, capable of triggering a massive cyberspace colonization process that paradoxically would also affect the everyday life and more in general, on human space perception. The contribution aims at analyzing the application systems used for low cost 3d photogrammetry by means of a precise pipeline, clarifying how a 3d model is generated, automatically retopologized, textured by color painting or photo-cloning techniques, and optimized for parametric insertion on virtual exploration platforms. Workflow analysis will follow some case studies related to photomodeling, digital retopology and "virtual 3d transfer" of some small archaeological artifacts and an architectural compartment corresponding to the pronaus of Aurum, a building designed in the 1940s by Michelucci. All operations will be conducted on cheap or free licensed software that today offer almost the same performance as their paid counterparts, progressively improving in the data processing speed and management.
TOWARDS GESTURE-BASED MULTI-USER INTERACTIONS
IN COLLABORATIVE VIRTUAL ENVIRONMENTS
Authors: Pretto N. , Poiesi F.
Published: November 2017

Abstract. We present a virtual reality (VR) setup that enables multiple users to participate in collaborative virtual environments and interact via gestures. A collaborative VR session is established through a network of users that is composed of a server and a set of clients. The server manages the communication amongst clients and is created by one of the users. Each user’s VR setup consists of a Head Mounted Display (HMD) for immersive visualisation, a hand tracking system to interact with virtual objects and a single-hand joypad to move in the virtual environment. We use Google Cardboard as a HMD for the VR experience and a Leap Motion for hand tracking, thus making our solution low cost. We evaluate our VR setup though a forensics use case, where real-world objects pertaining to a simulated crime scene are included in a VR environment, acquired using a smartphone-based 3D reconstruction pipeline. Users can interact using virtual gesture-based tools such as pointers and rulers.

Published: November 2017

Abstract. Nowadays, 3D digital imaging proposes effective solutions for preserving the expression of human creativity across the centuries, as well as is a great tool to guarantee global dissemination of knowledge and wide access to these invaluable resources of the past. Nevertheless, in several cases, a massive digitalisation of cultural heritage items (from the archaeological site up to the monument and museum collections) could be unworkable due to the still high costs in terms of equipment and human resources: 3D acquisition technologies and the need of skilled team within cultural institutions. Therefore, it is necessary to explore new possibilities offered by growing technologies: the lower costs of these technologies as well as their attractive visual quality constitute a challenge for researchers. Besides these possibilities, it is also important to consider how information is spread through graphic representation of knowledge. The focus of this study is to explore the potentialities and weaknesses of a newly released low cost device in the cultural heritage domain, trying to understand its effective usability in museum collections. The aim of the research is to test their usability, critically analysing the final outcomes of this entry level technology in relation to the other better assessed low cost technologies for 3D scanning, such as Structure from Motion (SfM) techniques (also produced by the same device) combined with dataset generated by a professional digital camera. The final outcomes were compared in terms of quality definition, time processing and file size. The specimens of the collections of the Civic Museum Castello Ursino in Catania have been chosen as the site of experimentation.
UTILIZATION OF LARGE SCALE SURFACE MODELS
FOR DETAILED VISIBILITY ANALYSES
Authors: Caha J. , Kačmařík M.
Published: November 2017

Abstract. This article demonstrates utilization of large scale surface models with small spatial resolution and high accuracy, acquired from Unmanned Aerial Vehicle scanning, for visibility analyses. The importance of large scale data for visibility analyses on the local scale, where the detail of the surface model is the most defining factor, is described. The focus is not only the classic Boolean visibility, that is usually determined within GIS, but also on so called extended viewsheds that aims to provide more information about visibility. The case study with examples of visibility analyses was performed on river Opava, near the Ostrava city (Czech Republic). The multiple Boolean viewshed analysis and global horizon viewshed were calculated to determine most prominent features and visibility barriers of the surface. Besides that, the extended viewshed showing angle difference above the local horizon, which describes angular height of the target area above the barrier, is shown. The case study proved that large scale models are appropriate data source for visibility analyses on local level. The discussion summarizes possible future applications and further development directions of visibility analyses.
When probabilistic seismic hazard climbs volcanoes: the Mt. Etna case, Italy – Part 2: Computational implementation and first results

Abstract. This paper describes the model implementation and presents results of a probabilistic seismic hazard assessment (PSHA) for the Mt. Etna volcanic region in Sicily, Italy, considering local volcano-tectonic earthquakes. Working in a volcanic region presents new challenges not typically faced in standard PSHA, which are broadly due to the nature of the local volcano-tectonic earthquakes, the cone shape of the volcano and the attenuation properties of seismic waves in the volcanic region. These have been accounted for through the development of a seismic source model that integrates data from different disciplines (historical and instrumental earthquake datasets, tectonic data, etc.; presented in Part 1, by Azzaro et al., 2017) and through the development and software implementation of original tools for the computation, such as a new ground-motion prediction equation and magnitude–scaling relationship specifically derived for this volcanic area, and the capability to account for the surficial topography in the hazard calculation, which influences source-to-site distances. Hazard calculations have been carried out after updating the most recent releases of two widely used PSHA software packages (CRISIS, as in Ordaz et al., 2013; the OpenQuake engine, as in Pagani et al., 2014). Results are computed for short- to mid-term exposure times (10 % probability of exceedance in 5 and 30 years, Poisson and time dependent) and spectral amplitudes of engineering interest. A preliminary exploration of the impact of site-specific response is also presented for the densely inhabited Etna's eastern flank, and the change in expected ground motion is finally commented on. These results do not account for M  >  6 regional seismogenic sources which control the hazard at long return periods. However, by focusing on the impact of M  <  6 local volcano-tectonic earthquakes, which dominate the hazard at the short- to mid-term exposure times considered in this study, we present a different viewpoint that, in our opinion, is relevant for retrofitting the existing buildings and for driving impending interventions of risk reduction.
Integrating faults and past earthquakes into a probabilistic seismic hazard model for peninsular Italy
Authors: Valentini Alessandro , Visini Francesco , Pace Bruno
Published: November 2017

Abstract. Italy is one of the most seismically active countries in Europe. Moderate to strong earthquakes, with magnitudes of up to ∼ 7, have been historically recorded for many active faults. Currently, probabilistic seismic hazard assessments in Italy are mainly based on area source models, in which seismicity is modelled using a number of seismotectonic zones and the occurrence of earthquakes is assumed uniform. However, in the past decade, efforts have increasingly been directed towards using fault sources in seismic hazard models to obtain more detailed and potentially more realistic patterns of ground motion. In our model, we used two categories of earthquake sources. The first involves active faults, and using geological slip rates to quantify the seismic activity rate. We produced an inventory of all fault sources with details of their geometric, kinematic, and energetic properties. The associated parameters were used to compute the total seismic moment rate of each fault. We evaluated the magnitude–frequency distribution (MFD) of each fault source using two models: a characteristic Gaussian model centred at the maximum magnitude and a truncated Gutenberg–Richter model. The second earthquake source category involves grid-point seismicity, with a fixed-radius smoothed approach and a historical catalogue were used to evaluate seismic activity. Under the assumption that deformation is concentrated along faults, we combined the MFD derived from the geometry and slip rates of active faults with the MFD from the spatially smoothed earthquake sources and assumed that the smoothed seismic activity in the vicinity of an active fault gradually decreases by a fault-size-driven factor. Additionally, we computed horizontal peak ground acceleration (PGA) maps for return periods of 475 and 2475 years. Although the ranges and gross spatial distributions of the expected accelerations obtained here are comparable to those obtained through methods involving seismic catalogues and classical zonation models, the spatial pattern of the hazard maps obtained with our model is far more detailed. Our model is characterized by areas that are more hazardous and that correspond to mapped active faults, while previous models yield expected accelerations that are almost uniformly distributed across large regions. In addition, we conducted sensitivity tests to determine the impact on the hazard results of the earthquake rates derived from two MFD models for faults and to determine the relative contributions of faults versus distributed seismic activity. We believe that our model represents advancements in terms of the input data (quantity and quality) and methodology used in the field of fault-based regional seismic hazard modelling in Italy.
Storm-induced water dynamics and thermohaline structure at the tidewater Flade Isblink Glacier outlet to the Wandel Sea (NE Greenland)

Published: November 2017

Abstract. In April 2015, an ice-tethered conductivity–temperature–depth (CTD) profiler and a down-looking acoustic Doppler current profiler (ADCP) were deployed from the landfast ice near the tidewater glacier terminus of the Flade Isblink Glacier in the Wandel Sea, NE Greenland. The 3-week time series showed that water dynamics and the thermohaline structure were modified considerably during a storm event on 22–24 April, when northerly winds exceeded 15 m s−1. The storm initiated downwelling-like water dynamics characterized by on-shore water transport in the surface (0–40 m) layer and compensating offshore flow at intermediate depths. After the storm, currents reversed in both layers, and the relaxation phase of downwelling lasted ∼ 4 days. Although current velocities did not exceed 5 cm s−1, the enhanced circulation during the storm caused cold turbid intrusions at 75–95 m depth, which are likely attributable to subglacial water from the Flade Isblink Ice Cap. It was also found that the semidiurnal periodicities in the temperature and salinity time series were associated with the lunar semidiurnal tidal flow. The vertical structure of tidal currents corresponded to the first baroclinic mode of the internal tide with a velocity minimum at ∼ 40 m. The tidal ellipses rotate in opposite directions above and below this depth and cause a divergence of tidal flow, which was observed to induce semidiurnal internal waves of about 3 m height at the front of the glacier terminus. Our findings provide evidence that shelf–basin interaction and tidal forcing can potentially modify coastal Wandel Sea waters even though they are isolated from the atmosphere by landfast sea ice almost year-round. The northerly storms over the continental slope cause an enhanced circulation facilitating a release of cold and turbid subglacial water to the shelf. The tidal flow may contribute to the removal of such water from the glacial terminus.
Extension parallel to the rift zone during segmented fault growth: application to the evolution of the NE Atlantic

Published: November 2017

Abstract. The mechanical interaction of propagating normal faults is known to influence the linkage geometry of first-order faults, and the development of second-order faults and fractures, which transfer displacement within relay zones. Here we use natural examples of growth faults from two active volcanic rift zones (Koa`e, island of Hawai`i, and Krafla, northern Iceland) to illustrate the importance of horizontal-plane extension (heave) gradients, and associated vertical axis rotations, in evolving continental rift systems. Second-order extension and extensional-shear faults within the relay zones variably resolve components of regional extension, and components of extension and/or shortening parallel to the rift zone, to accommodate the inherently three-dimensional (3-D) strains associated with relay zone development and rotation. Such a configuration involves volume increase, which is accommodated at the surface by open fractures; in the subsurface this may be accommodated by veins or dikes oriented obliquely and normal to the rift axis. To consider the scalability of the effects of relay zone rotations, we compare the geometry and kinematics of fault and fracture sets in the Koa`e and Krafla rift zones with data from exhumed contemporaneous fault and dike systems developed within a > 5×104 km2 relay system that developed during formation of the NE Atlantic margins. Based on the findings presented here we propose a new conceptual model for the evolution of segmented continental rift basins on the NE Atlantic margins.
Seasonal variations of the backscattering coefficient measured by radar
altimeters over the Antarctica Ice Sheet
Authors: Adodo Fifi I. , Remy Frédérique , Picard Ghislain
Published: November 2017

Abstract. Spaceborne radar altimeter is a valuable tool for observing the Antarctica Ice Sheet. The radar wave penetration into the snow provides information both on the surface and the subsurface of the snowpack due to its dependence on the snow properties. However this penetration also induces a negative bias on the estimated surface elevation. Empirical corrections of this space and time-varying bias are usually based on the backscattering coefficient variability. We investigate the spatial and seasonal variations of the backscattering coefficient at the S (3.2 GHz), Ku (13.6 GHz) and Ka (37 GHz) bands. We identified two clearly marked zones over the continent, one with the maximum of Ku band backscattering coefficient in the winter and another with the maximum in the summer. To explain this, we performed a sensitivity study of the backscattering coefficient at the S, Ku and Ka bands to surface snow density, snow temperature and snow grain size using an electromagnetic model. The results show that the seasonal cycle of the backscattering coefficient at the Ka band, is dominated by the volume echo and is mainly explained by snow temperature. In contrast, the cycle is dominated by the surface echo at the S band. At Ku band, which intermediate in terms of wavelength between S and Ka bands, the seasonal cycle is in the first zone dominated by the volume echo and by the surface echo in the second one. Such seasonal and spatial variations of the backscattering coefficient at different radar frequencies should be taken into account the for more precise estimation of the surface elevation changes.
3-D shear-layer model for the simulation of multiple wind turbine wakes: description and first assessment
Authors: Trabucchi Davide , Vollmer Lukas , Kühn Martin
Published: November 2017

Abstract. The number of turbines installed in offshore wind farms has strongly increased in the last years and at the same time the need for more precise estimations of the wind farm efficiency too. In this sense, the interaction between wakes has become a relevant aspect for the definition of a wind farm layout, for the assessment of its annual energy yield and for the evaluation of wind turbine fatigue loads. For this reason, accurate models for multiple overlapping wakes are a main concern of the wind energy community. Existing engineering models can only simulate single wakes, which are superimposed when they are interacting in a wind farm. This method is a practical solution, but it is not fully supported by a physical background. The limitation to single wakes is given by the assumption that the wake is axisymmetric. As an alternative, we propose a new shear-layer model that is based on the existing engineering wake models but is extended to also simulate non-axisymmetric wakes. In this paper, we present the theoretical background of the model and four application cases. We evaluate the new model for the simulation of single and multiple wakes using large-eddy simulations as reference. In particular, we report the improvements of the new model predictions in comparison to a sum-of-squares superposition approach for the simulation of three interacting wakes. The lower deviation from the reference considering single and multiple wakes encourages the further development of the model and promises a successful application for the simulation of wind farm flows.
The impact of customer images on online purchase decisions: Evidence from a Chinese C2C Web site
Authors: Dai Mingming , Van Hove Leo
Published: November 2017

The influence of electronic word-of-mouth (eWOM) on consumers’ online purchase decisions is well-documented. However, little is known about the impact of customer images, a recent form of eWOM. The present paper reports on an exploratory survey among 215 young users of the Chinese C2C shopping Web site Taobao.com. The idea was to test whether the so-called information adoption model — and in particular a variant used in earlier research on an online consumer community — could be transposed to the case of customer images. We find that the perceived quality of customer images — and in particular their ‘comprehensiveness’ — has a significant positive impact on purchase intention. This suggests that shopping sites should encourage customers to share high-quality customer images. From a methodological perspective, the limited reliability of two of the quality dimensions (namely ‘relevance’ and ‘timeliness’) catches the eye. This suggests that there is a need for a dedicated theoretical framework and for scales that take into account the specific nature of customer images. Simply transposing scales that have been validated for other forms of eWOM would not appear to be the best approach.
The transformative power of the thumbnail image: Media logistics and infrastructural aesthetics
Authors: Thylstrup Nanna , Teilmann-Lock Stina
Published: November 2017

Thumbnail images are discreet, yet central navigational tools in increasingly complex visual information environments. Indeed, without thumbnail images there would be no image search: they are an inherent part of the information architecture of most digital information platforms. Yet, how might we understand the role of the thumbnail as an attention technology in the digital economy? And what kind of aesthetic does it produce? This paper examines the legal negotiations of the thumbnail image and the ensuing decision to conceptualize the thumbnail as a functional image against the cultural history of visual attention technologies and the aesthetics of their connective function. Such an endeavour, we propose, allows us to understand and appreciate the significant digital economy and particular aesthetic of the thumbnail image despite its apparent subtlety.
Exploring HIV-AIDS interests in the MENA region using Internet based searches
Authors: Al-Rawi Ahmed
Published: November 2017

Due to the scarcity of official data on sexually transmitted diseases in the Middle East and North Africa region (MENA), it becomes important to seek alternative indications on the online information interests and possible spread of such diseases. This paper uses news stories from 10 Arabic media outlets, Wikipedia views, and data from Google Trends as well as social media on the HIV-AIDS epidemic. In order to investigate whether Internet searches are driven or influenced by media coverage, the correlation between media coverage and Internet searches is examined. The results indicate that there are very weak to moderate correlations between the two as media coverage of HIV-AIDS is not a good indicator of public attention. Data sources that are more accessible, like Google and Wikipedia searches and social media, can provide a better understanding of public information interests. Also, data retrieved from Google Trends in relation to the search terms “AIDS treatment” and “AIDS symptoms” provide important indicators on the top cities from which searches often originate. The findings of the study can aid health practitioners in identifying interest in and awareness of HIV-AIDS in the MENA region.

The fear for the future of human existence on this planet has made it necessary to pay special attention to studies that are related to the environment. In view of this, this study attempts to re-examine the environmental Kuznets curve in the midst of selected macroeconomic variables in Nigeria. The study estimated the relationship between carbon dioxide emission and some selected macroeconomic variables such as energy consumption (proxied by energy price); gross domestic product; population density; trade openness; ratio of manufacturing as a share of GDP and foreign direct investment using the ARDL model. With the adoption of secondary data for the period of 1981 to 2016 obtained from the world development indicator, the findings validated an N-shaped relationship between economic growth and the pollution in Nigeria in the midst of other Macroeconomic variables and based on this, it was recommended among others the building of a strong and effective environmental regulatory framework for the Nigerian economy and the adoption of clean technologies for the Nigerian economy

“The Next Last of the Breed”: Dynastic Succession and Resistance in an Appalachian Storytelling Clan
Authors: Sobol Joseph
Published: November 2017

Appalachian storyteller Ray Hicks was often described metonymically as “the last of his breed.” After Ray’s death in 2003, it emerged that several younger extended family members were capable of re-telling his stories. While space exists in the professional storytelling world for next-generation tellers to step into the family storytelling mantle, internal and external factors have resisted this development. The essay explores attitudes toward private and public performance, memory, identity, and honor among the descendants and relatives of a dominant Appalachian tradition-bearer.

Aim of the study: To analyze the impact of the 1998 wildfire on dwarf pine (Pinus culminicola) population stands 18 years after the fire.Area of study: Cerro el Potosí, Nuevo León (México)Material and methods: We measured regeneration, biovolume of individuals, diversity and species composition in unburned and burned plots randomly selected in the area.Main results: Recovery was very slow, with limited dense natural regeneration and very slow growth. Significant differences between control and burned plots were found with respect to regeneration, species composition, evenness and soil nutrients, suggesting that fire could promote natural regeneration and biodiversity in these communities.Research highlights: Management efforts are necessary to maintain a natural fire regime and ensure grazing exclusion in order to favor the conservation of the community dominated by this rare species P. culminicola.
The Weight-Bearing Shoulder
Authors: Patel Ronak M. , Gelber Jonathan D. , Schickendantz Mark S.
Published: November 2017

The shoulder achieves a wide spectrum of motion, and in a subset of patients, including those who use manual wheelchairs and upper extremity walking aids, the shoulder also serves as the primary weight-bearing joint. Because the weight-bearing shoulder is subject to considerable joint reaction forces and overuse, a broad spectrum of pathology can affect the joint. The combination of muscle imbalance and repetitive trauma presents most commonly as subacromial impingement syndrome but can progress to other pathology. Patients with high-level spinal cord injury, leading to quadriplegia and motor deficits, have an increased incidence of shoulder pain. Understanding the needs of patients who use manual wheelchairs or walking aids can help the physician to better comprehend the pathology of and better manage the weight-bearing shoulder.
Pathological Voice Signal Analysis Using Machine Learning Based Approaches
Authors: Alemami Yahia , Almazaydeh Laiali
Published: November 2017

Voice signal analysis is becoming one of the most significant examination in clinical practice due to the importance of extracting related parameters to reflect the patient's health. In this regard, various acoustic studies have been revealed that the analysis of laryngeal, respiratory and articulatory function may be efficient as an early indicator in the diagnosis of Parkinson disease (PD). PD is a common chronic neurodegenerative disorder, which affects a central nervous system and it is characterized by progressive loss of muscle control. Tremor, movement and speech disorders are the main symptoms of PD. The diagnosis decision of PD is obtained by continued clinical observation which relies on expert human observer. Therefore, an additional diagnosis method is desirable for most comfortable and timely detection of PD as well as faster treatment is needed. In this study, we develop and validate automated classification algorithms, which are based on Naïve Bayes and K- Nearest Neighbors (KNN) using voice signal measurements to predict PD. According to the results, the diagnostic performance provided by the automated classification algorithm using Naïve Bayes was superior to that of the KNN and it is useful as a predictive tool for PD screening with a high degree of accuracy, approximately 93.3%.
The Emerging Retail Market in Myanmar - An Institutional Perspective of Foreign Retailers’ Market Entry Decisions
Authors: Hardaker Sina
Published: November 2017

In contrast to most of its Southeast Asian neighbors, Myanmar still lacks a vibrant retail landscape. Yet, given the political and economic opening-up of the country and the abolition of many sanctions since 2013, commercial interest in Myanmar is growing rapidly. While political and economic reforms sweep across the country, retailers are now eyeing-up the formerly reclusive nation for opportunities. Still, the question remains as to how optimistic the outlook of the Myanmar retailing industry really is? This paper explores and analyses the developments of Myanmar’s retail sector to date. Within the decision making process, companies operate within an external and an internal environment that consist of political, cognitive and sociological elements. A company’s behavior and decision making processes are affected by both environments. This study applies institutional theory as a complementary framework in order to evaluate international retailers’ foreign market entry choices with special regard to Myanmar and evaluates the main factors influencing decisions for, or against market entry. It concludes by proposing institutional theory as complementary to, and not substitutive of, existing theories such as Dunning's eclectic theory or transaction cost analysis.

Are they all stray finds? Metal detector finds and the potential for preserved contexts below the plough soilIn Vestfold County we have since 2013 seen a marked rise in metal detecting finds being delivered to the county archaeologists by amateur detectorists. These finds are a source of both joy and grief for archaeologists all over Norway. Should we see these finds as noncontextual random finds or do they relate to a more complex situation over which we simply do not have full insight? In this article we discuss the possibilities of investigating sites with clusters of metal detecting finds with geophysical prospection. Two case studies in Vestfold County are presented, both of which have provided clusters of metal finds, and we compare the results from the metal detecting with results from geophysical prospection. By doing so our aim is to contribute to further discussion of the possibilities of preserved archaeological contexts under the plow soil.

The objective of the paper was to investigate the main factors determining the yield of fat in goat milk in the dairy goat population of Lithuania. The research was carried out on a total of 1,079 dairy goats (4 breeds: Czech White Shorthaired (n = 610), Saanen (n = 364), Lithuanian native (n = 94) and Anglo-Nubian (11)) in 7 dairy farms. The average milk yield during lactation was 797.42 (±53.3) kg. The average milk fat content was 4.14% (±0.4). The research of the goat milk fat content demonstrated that the indicators investigated in different herds varied. The highest milk fat content in percent was determined among AngloNubian – 5.2%. The milk fat content of all breeds of goats increased with increasing the parity up to the 4–6th parity, respectively, and started decreasing then, after reaching the peak. While assessing the quantity of milk fat during the stage of lactation, the highest milk fat content was determined during the first months (4.5–4.7%) and at the end of lactation (4.5%). The research performed by us showed that such factors as breed, parity, stage of lactation and herd had an impact on the quantity of goat milk fat.
¿Cómo se enseña la Ilustración en 2.º de Bachillerato? Un análisis de los libros de texto, sus contenidos y la cuestión de género.
Authors: Rausell Guillot Helena
Published: November 2017

Con el presente artículo tratamos de analizar cómo se enseña y cómo se ha enseñado el movimiento ilustrado en las aulas de secundaria de nuestro país, a través del estudio de algunos materiales curriculares de 2.º de Bachillerato correspondientes a la asignatura de Historia de España. Estos han sido elaborados en distintos momentos, los últimos años del periodo de vigencia de la Ley de Ordenación General del Sistema Educativo (1990) y en el marco de la actual Ley Orgánica para la Mejora de la Calidad Educativa (2013). Nuestro objetivo es tratar averiguar si las innovaciones aportadas por la historiografía más reciente sobre la Ilustración se han trasladado o no a los mismos. También si estos incorporan la perspectiva de género y, de ser así, de qué manera lo hacen. Los resultados demuestran el mantenimiento en ellos de una visión bastante tradicional a la hora de abordar el movimiento ilustrado, aunque creemos poder detectar alguna evolución y una tímida incorporación de ciertas cuestiones referentes a la historia de las mujeres o las nuevas formas de sociabilidad y trasmisión de las ideas ilustradas.

Our article tries to study the way Enlightenment is taught and it has been taught in Spanish high schools, through analyzing some secondary text books on History of Spain. Those textbooks have been written at various moments. In fact, they correspond to two different organic laws, LOGSE (1990) and the current LOMCE (2013). Our main aim is to find out if recent historiographic approaches and contributions on Enlightenment are included. We would like also to know if they consider, or not, gender perspective and, if so, how it is understood. Our results show how textbooks keep, in general, traditional approaches to Enlightenment. However, we could detect a slight evolution with the incorporation of a certain number of questions on women history and new sociability approaches in more recent textbook.
The Role of Local History in Elementary and Secondary Schools in Slovenia: An Evaluation of the Centre for School and Outdoor Education.
Authors: Trškan Danijela
Published: November 2017

El objetivo del artículo es investigar qué asignaturas de la escuela primaria y secundaria contienen los elementos de la historia local, qué tipos de actividades se ofrecen en el CŠOD (Centro de actividades escolares y extracurriculares de Eslovenia), y qué papel tiene la historia local en la comprensión de la historia nacional, europea y mundial en Eslovenia. El análisis del programa y las actividades del centro han evidenciado que el CŠOD ofrece métodos y actividades apropiados para las asignaturas de ciencias sociales relacionadas con diversos lugares de Eslovenia. El aprendizaje fuera del aula y la exploración del lugar natal permiten a los estudiantes entender mejor a las personas, los acontecimientos y la vida cotidiana del pasado, los cambios y las continuidades, junto a sus razones y consecuencias, así como las necesidades, los derechos y las responsabilidades de las personas que viven en el presente. Teniendo esto en cuenta el artículo sugiere que el conocimiento de la historia local proporciona una base importante para la comprensión del entorno regional, nacional, europeo y mundial.

The aim of the article is to investigate which elementary and secondary school subjects cover topics related to local history, what kind of activities are offered by the Centre for School and Outdoor Education, and what is the role of local history in understanding national, European and world history in Slovenia. Analysing the programme and activities of the Centre, it becomes evident that the Centre offers suitable methods and activities for those social science subjects that relate to various locations in Slovenia. Learning outside the classroom and exploring the hometown enable students to better understand the people, events and everyday life in the past, the changes and continuities and their reasons and consequences, as well as the needs, rights and responsibilities of people living in the present. On this basis, the article suggests that knowledge of local history provides an important basis for the understanding of the regional, national, European and global environment.
Intensified Mega‐ENSO Has Increased the Proportion of Intense Tropical Cyclones Over the Western Northwest Pacific Since the Late 1970s

Published: November 2017

Intense tropical cyclones (TCs) formed over the western part of the western North Pacific (WWNP) pose greater coastal risk than those formed over the eastern part (EWNP). Here we show that the proportion of intense TCs relative to all TCs (PITC) locally formed over the WWNP west of 140°E has increased significantly by about 16% to 20%, or equivalently almost doubled, since the late 1970s. However, the PITC over the EWNP has experienced little change. This sharp west‐east contrast is primarily driven by the La Niña‐like sea surface temperature (SST) pattern in the Pacific, identified as the mega El Niño–Southern Oscillation (ENSO) in previous studies. It is shown that the strong warming in the WWNP has contributed greatly to the increased PITC. In the EWNP, the dynamical conditions associated with the intensified mega‐ENSO play a vital opposite role in offsetting and even overweighting the effect of local SST warming.

At the eastern Qilian Shan mountain front in the NE Tibetan Plateau, the Minle‐Damaying Fault (MDF), the southernmost fault of the North Frontal Thrust (NFT) system, has previously been proposed as an inactive structure during the Holocene. Here we present a detailed record of six strath terraces of the Xie River that document the history of active deformation of the MDF. One optically stimulated luminescence dating sample constrains abandonment of the highest terrace T6at 12.7 ± 1.4 ka. The formation ages of the lower terraces (T4–T1) are dated by AMS14C dating. The cumulative vertical offsets of the MDF recorded by these terraces are determined as 12.2 ± 0.4 m (T6), 8.0 ± 0.4 m (T5), 6.4 ± 0.4 m (T4), 4.6 ± 0.1 m (T3), and 3.2 ± 0.2 m (T1c) by an unmanned aerial vehicle system, respectively. A long‐term vertical slip rate of the MDF of 0.9 ± 0.2 mm/yr is then estimated from the above data of terrace age and vertical offset by a linear regression. Assuming that the fault dip of 35 ± 5° measured at the surface is representative for the depth‐averaged fault dip, horizontal shortening rates of 0.83–1.91 mm/yr are inferred for the MDF. Our new data show that the proximal fault (the MDF) of the NFT system at the eastern Qilian Shan mountain front has remained active when the deformation propagated basinward, a different scenario from that observed at both the western and central Qilian Shan mountain front.
