On the quality of RS41 radiosonde descent data
Authors: Ingleby Bruce , Motl Martin , Marlton Graeme , Edwards David , Sommer Michael , von Rohden Christoph , Vömel Holger , Jauhiainen Hannu
Published: June 2021

Abstract. Radiosonde descent profiles have been available from tens of stations for several years now – mainly from Vaisala RS41 radiosondes. They have been compared with the ascent profiles, with ECMWF short-range forecasts and with co-located radio-occultation retrievals. Over this time our understanding of the data has grown, and the comparison also shed some light on radiosonde ascent data. It has become clear that the fall rate is very variable and that it is an important factor, with high fall rates being associated with temperature biases, especially at higher altitudes. Ascent winds are affected by pendulum motion, on average descent winds are less affected by pendulum motion and are smoother. It is plausible that the true wind variability in the vertical lies between that shown by ascent and descent profiles. The discrepancy indicates the need for reference wind measurements.
Spatial distribution of groundwater recharge, based on regionalized soil moisture models in Wadi Natuf karst aquifers, Palestine
Authors: Messerschmid Clemens , Aliewi Amjad
Published: June 2021

Abstract. While groundwater recharge is considered fundamental to hydrogeological insights and basin management, only relatively little attention has been paid to its spatial distribution. And in ungauged catchments it has rarely been quantified, especially on the catchment scale. For the first time, this study attempts such analysis, in a previously ungauged basin. Our work based on field data of several soil moisture stations, which represent five geological formations of karst rock in Wadi Natuf, a semi-arid to sub-humid Mediterranean catchment in the occupied Palestinian West Bank. For that purpose, recharge was conceptualized as deep percolation from soil moisture under saturation excess conditions, which had been modelled parsimoniously and separately with different formation-specific recharge rates. For the regionalisation, inductive methods of empirical field-measurements and observations were combined with deductive approaches of extrapolation, following the recommendations for hydrological Prediction in Ungauged Basins (PUB), by the International Association of Hydrological Sciences (IAHS). Our results show an average annual recharge estimation in Wadi Natuf Catchment (103 km2), ranging from 24 to 28 Mm3/yr, equivalent to recharge coefficients (RC) of 39–46 % of average annual precipitation. Thus, for the first time, formation-specific RC-values could be derived, assessed and quantified in their spatial distribution, and by creating a schematic conceptual basin classification framework for regionalisation that is also applicable in many comparable sedimentary basins in the Mediterranean and worldwide.
RADIOMETRIC QUALITY ASSESSMENT FOR MAXAR HD IMAGERY
Authors: Yalcin I. , Kocaman S. , Saunier S. , Albinet C.
Published: June 2021

Abstract. The requirement for very high-resolution satellite imagery by different applications has been increasing continuously. Several commercial and government-supported missions provide sub-meter spatial resolutions from optical sensors aboard Earth Observation (EO) satellites. The MAXAR satellite constellation acquires images with up to 30 cm Ground Sampling Distances (GSDs); and the High-Definition (HD) image production technology developed by MAXAR doubles the resolution by using artificial intelligence methods. Although the spatial resolution is one of the most important image quality metrics, several other factors indicated by diverse radiometric and geometric characteristics may circumscribe the usability of data in different projects. As part of mandatory activities of European Space Agency (ESA), Earthnet Programme provides a framework for integrating Third-Party Missions into the overall EO strategy and promotes the international use of the data. The Earthnet Data Assessment Pilot (EDAP) project aims at assessing the quality and the suitability of TPMs, and provides a communication platform between mission providers to ensure the coherence of the systems. In this study, the radiometric quality of the MAXAR HD products was evaluated within the EDAP project framework by using several General Image-Quality Equation (GIQE) metrics, visual inspections, and comparative assessments with orthophotos obtained from an Unmanned Aerial Vehicle (UAV) platform and with the original (non-HD) orthophotos with 30 cm resolutions. The results show that the spatial resolution improvements are observable in urban areas, where sharp edges are present. However, blurring and color noise patterns also occured in the HD images.

Authors: Souza T. G. D. , Fonseca F. D. R. , Fernandes V. D. O. , Pedrassoli J. C.
Published: June 2021

Abstract. The exploratory spatial analysis allows to describe patterns of spatial distribution, to identify clusters and outliers through specific techniques of spatial association and data model. The objective of the study is to verify the spatial autocorrelation between the mean prices of the housing obtained from web scraping technique in online platforms in the city of Salvador, on the coast of northeast Brazil. For this purpose, the Global Moran’s Index (which provides a general measure of association) and the Local Index of Spatial Association (LISA) were calculated. The results of Global Moran’s Index indicate positive autocorrelation between the mean prices of housing prices in the 163 districts of the municipally that are statistically significant, such as identification of clusters through LISA. Thus, the analysis allows to conclude the existence of a heterogeneous pattern in the distribution of these mean prices in the urban space of Salvador.
GENERATIVE ADVERSARIAL NETWORKS TO GENERALISE URBAN AREAS IN TOPOGRAPHIC MAPS
Authors: Courtial A. , Touya G. , Zhang X.
Published: June 2021

Abstract. This article presents how a generative adversarial network (GAN) can be employed to produce a generalised map that combines several cartographic themes in the dense context of urban areas. We use as input detailed buildings, roads, and rivers from topographic datasets produced by the French national mapping agency (IGN), and we expect as output of the GAN a legible map of these elements at a target scale of 1:50,000. This level of detail requires to reduce the amount of information while preserving patterns; covering dense inner cities block by a unique polygon is also necessary because these blocks cannot be represented with enlarged individual buildings. The target map has a style similar to the topographic map produced by IGN. This experiment succeeded in producing image tiles that look like legible maps. It also highlights the impact of data and representation choices on the quality of predicted images, and the challenge of learning geographic relationships.
AI IN SUPPORT TO WATER QUALITY MONITORING

Published: June 2021

Abstract. This study explores the possibility of using Artificial Intelligence (AI) as a means to support water monitoring. More precisely, it addresses the issue of the quality and reliability of Citizen Science data. The paper addresses the tools and data of the SIMILE (Informative System for the Integrated Monitoring of Insubric Lakes and their Ecosystems) project in order to develop an open pre-filtering system for Volunteer Geographic Information (VGI) of lake water monitoring at the global scale. The goal is to automatically determine the presence of harmful phenomena (algae and foams) in the images uploaded by citizen scientists to reduce the time required for a manual check of the contributions. The task is challenging because of the heterogeneity of the data that consist in geotagged pictures taken without specific instructions. For this purpose, different tools and deep learning techniques have been tested (Clarifai platform, a Convolutional Neural Network (CNN), and an object detection algorithm called faster Region-based CNN (R-CNN). The original dataset composed by the observations of SIMILE – Lake Monitoring application, has been integrated with the results of both keyword and image searches on web engines (Google, Bing, etc) and crawling Flickr data. The performances of the different algorithms are presented for their capability of detecting the presence and correctly labelling the phenomenon together with some possible strategies to improving them in the future.
BUILDING OPENDRIVE MODEL FROM MOBILE MAPPING DATA
Authors: Barsi M. , Barsi A.
Published: June 2021

Abstract. The development of self-driving vehicles has been efficiently accelerated by applying computer simulations. These environments can achieve the best result only if reality has been digitized: highly accurate and detailed maps are required. The high-definition (HD) maps aim to fulfill these requests. Companies and academia are seeking adequate technology, where OpenDRIVE standard seems to win this race.A software was developed to create high-definition road models for self-driving car testing purposes, which can also be used in driving simulators, for example, for testing vehicle prototypes.The data of a sample area was received located in northern Budapest, which included inconsistent information about the lanes of the road network. The top-priority task was to build a highly structured, consistent model satisfying this open standard, an increasingly popular modeling format to describe the environment for various simulating software. In order to do that, the relevant information had to be extracted from an AutoCAD file. The result was a collection of points that was added to a software module written in C++. The code has built a structure from those points, including determining connections between lanes, building roads from the lanes, determining connections between roads, adding road marks, and building the final OpenDRIVE model.Two different sets of data have been used thus far in the software: a circa 8 km long road section and a separate junction – meaning about 20,000 points to process. Two independent models were created; both were tested in various automotive simulators – including IPG CarMaker, probably the most well-known simulating tool used in car manufacturing – which showed that both are indeed correct. The overall time required to build those models from simple text files to well-structured OpenDRIVE models is no more than two minutes, while before the software development – when all of those aforementioned processes were done by humans – it required several weeks, if not months.The software is already capable of building basic road models but is nowhere near finished. Numerous other features can be added to it as well, for instance, traffic signs and signals and environmental elements such as roadside objects, trees, and buildings.
Technical note: Stability of tris pH buffer in artificial seawater stored in bags
Authors: Wolfe Wiley H. , Shipley Kenisha M. , Bresnahan Philip J. , Takeshita Yuichiro , Wirth Taylor , Martz Todd R.
Published: June 2021

Abstract. Equimolal tris (2-amino-2-hydroxymethyl-propane-1,3-diol) buffer in artificial
seawater is a well characterized and commonly used standard for oceanographic pH measurements. We evaluated the stability of tris pH when stored in purportedly gas-impermeable bags across a variety of experimental conditions, including bag type and storage in air vs. seawater over
300 d. Bench-top spectrophotometric pH analysis revealed that the pH of tris stored in bags decreased at a rate of 0.0058±0.0011 yr−1 (mean slope ±95 % confidence interval of slope). The upper and lower bounds of expected pH change at
t=365 d, calculated using the averages and confidence intervals of slope and intercept of measured pH change vs. time data, were −0.0042 and −0.0076 from initial pH. Analyses of total dissolved inorganic carbon
confirmed that a combination of CO2 infiltration and/or microbial
respiration led to the observed decrease in pH. Eliminating the change in pH of bagged tris remains a goal, yet the rate of pH change is lower than many processes of interest and demonstrates the potential of bagged tris for sensor calibration and validation of autonomous in situ pH measurements.
How realistic are the wakes of scaled wind turbine models?
Authors: Wang Chengyu , Campagnolo Filippo , Canet Helena , Barreiro Daniel J. , Bottasso Carlo L.
Published: June 2021

Abstract. The aim of this paper is to analyze to which extent wind tunnel experiments
can represent the behavior of full-scale wind turbine wakes. The question
is relevant because on the one hand scaled models are extensively used for
wake and farm control studies, whereas on the other hand not all wake-relevant physical characteristics of a full-scale turbine can be
exactly matched by a scaled model. In particular, a detailed scaling
analysis reveals that the scaled model accurately represents the principal
physical phenomena taking place in the outer shell of the near wake,
whereas differences exist in its inner core. A large-eddy simulation
actuator-line method is first validated with respect to wind tunnel
measurements and then used to perform a thorough comparison of the wake at
the two scales. It is concluded that, notwithstanding the existence of some
mismatched effects, the scaled wake is remarkably similar to the full-scale
one, except in the immediate proximity of the rotor.

Relationship between urban tourism traffic and tourism land use: A case study of Xiamen Island
Authors: Gao Yueer , Liao Yanqing , Wang Donggen , Zou Yongguang
Published: June 2021

The development of tourism leads to changes in land-use demands and patterns, which are complex and dynamic, in tourist cities. Functional differences in land use produce different travel needs and have different impacts on traffic, especially on tourism. This paper explores the relationship between tourism land use and tourism traffic. Taking Xiamen Island as an example, using multivariable linear regression models, tourism land use is divided into accommodation land use, shopping land use and restaurant land use as the independent variables of the model; and the origin-destination (OD) density of traffic analysis zones (TAZs) during National Day in 2018 (October 1 to 5) is chosen as the dependent variable. To compare the different impacts between tourism land use and tourism traffic during the tourism and non-tourism periods, the non-tourism period (March 11 to 15) is further studied. The results show the following: (1) Xiamen, as a tourism city, has not only regular traffic but also tourism traffic, and traffic during the tourism period is totally different than that in the non-tourism period. (2) Tourism land use has a considerable impact on both tourism traffic and non-tourism traffic, but the impact is greater during the tourism period than the non-tourism period. (3) In the morning peak hour of both the tourism period and the non-tourism period, accommodation land use shows prominent effects on traffic. In the evening peak hour, shopping land use significantly impacts traffic. The study provides a basis for urban tourism land use adjustment to achieve the sustainable development of tourism traffic.

Automation of the Spectrum, Automation and the Spectrum: Legal Challenges When Optimising Spectrum Use for Military Operations
Authors: Massingham Eve
Published: June 2021

The role of the electromagnetic spectrum in all manner of military operations is increasing. The same can be said for all aspects of our everyday civilian lives. Consequently, demand on the spectrum, both by the military and for civilian purposes, is increasing. The spectrum, while fully renewable, is not unlimited at any one point in time and allocation of the spectrum for optimum utilisation is key. This is raising a range of issues. Questions arise both because of the role of autonomous capabilities in devices that make use of the spectrum, which have the potential to create demand and interference challenges, and because of the valuable role that autonomous capabilities may play in managing the spectrum itself. This paper looks at attempts to use automation technologies to better utilise and manage the spectrum while noting the challenges created by signal interference and the ‘dual-use’ nature of this valuable resource.

Six groundings for Aboriginal and Torres Strait Islander story in the Australian creative writing classroom: Part 1
Authors: Collis Paul , Crawford Jen
Published: June 2021

‘All Australian children deserve to know the country that they share through the stories that Aboriginal people can tell them,’ write Gladys Idjirrimoonra Milroy and Jill Milroy (2008: 42). If country and story, place and voice are intertwined, it is vital that we make space in Australian creative writing classrooms for the reading and writing of Australian Indigenous story. What principles and questions can allow us to begin? We propose six groundings for this work:

1. Indigenous story is literary history, literary history is creative power. 2. We do culture together: culture becomes in collaboration, conscious or unconscious. 3. There is no such thing as Indigenous story, and yet it can be performed and known. 4. Country speaks, to our conceptions of voice and point of view. 5. History and memory are written in the land and on the body in bodies of practice. 6. Story transmits narrative responsibility. Narrative responsibility requires fierce listening.

This two-part paper will discuss each of these groundings as orienting and motivating principles for work we do as teachers of introductory creative writing units at the University of Canberra.
Overland to Malta
Authors: Bell Liam Murray
Published: June 2021

This essay details a research trip undertaken, by train and ferry, from Scotland to Malta. In doing so, it examines the creative process of writing my third novel dot dot dash and the research supporting the writing of the text. This aspect focuses on the historical and political context of Malta in the 1940s and 60s, as well as the linkages to the contemporary political situation in Scotland, in particular the Independence Referendum of 2014 and the Brexit vote of 2016, making use of examples from the creative narrative. dot dot dash is the story of a Maltese steward in the Royal Navy, Pietru, who has impacted on the lives of the three main characters in the book in various ways: as a father to young Joe; as a wartime husband to Beth; and, it emerges, as the man responsible for the horrific airman’s burns suffered by RAF pilot Stuart. It is a historical literary thriller.
Writing dislocation and disruption: The strange country of mothers of children with disabilities
Authors: Knight Kathryn
Published: June 2021

The sociocultural narratives available to mothers of children with disabilities exhort them to resist the impacts of their exclusion from mainstream discourses of motherhood, perform resilience, and re-interpret their marginalisation as a ‘different kind’ of mothering: a re-location. Such narratives function to suppress the complex emotions associated with the profound sense of dislocation experienced by these mothers. Two short pieces of writing are discussed, both of which use geographical metaphors to represent the competing themes of emotional containment versus disruption; the first is a tale widely circulated among families of children with disabilities, and the second is a memoir piece by the author. This discussion draws on the emergent literature by mothers of children with disability and academic research on families of children with disabilities, as well as on insights from Friedman’s work on the geographics of identity. The mother who seeks to write about her own dislocation must be prepared to speak against the dominant scripts that work to deny her emotional responses, while her own entitlement to self-represent is challenged by the compounded impacts of the discourses surrounding motherhood and disability.

In 21st century, developing communication and technology usage has increased people's interest and need for English and made English a common language in many fields such as science, culture, art, and economy. In this context, important changes have been made in English curricula in Turkey like many countries. In this study, the curricula between the years 1973-2017 were examined and discussed within the framework of similarities and differences. The study is conducted by qualitative research method. The curricula were examined based on the original and official document by using document analysis. When the findings were examined, it was understood that from 1973 to 2017, students became responsible for their own learning, teachers were transformed into guides and the learning-teaching environment was tried to be created in more technological structures. It has been observed that in the curricula of 2014 and beyond, the concepts of information and communication technologies, culture and values were dominant. During the assessment process, it was observed that classical assessment methods gave way to alternative assessment methods. According to the results, since development is a holistic process, more emotional and psychomotor objectives could be included in new curricula. Student motivation can increase positively with themes that appeal to students' interests more. New technologies should be introduced into teaching-learning process.

Schools are among the most important educational organizations where education and training activities are carried out. Along with the impossibility of the continuation of face-to-face education during the COVID-19 pandemic called new type of coronavirus, the distance education process has affected schools' ability to continue educational activities. School administrators, who are among the most important sections responsible for carrying out education and training services in schools properly, have played a significant role in the continuation of distance education during the present COVID-19 pandemic. Although school administrators have carried out the general activities of the school within the framework of social isolation rules, they have done all kinds of work to continue the distance education process efficiently. The aim of this study was to determine school administrators' views on distance education activities during the COVID-19 pandemic process. The results of the study are considered to be important since they will provide information on school administrators' perceptions of distance education during the COVID-19 pandemic process. The study was designed according to the qualitative research method. 46 school administrators (Principal or Deputy Principal) working in Elazığ province. A structured interview form was used as the data collection method. The "content analysis" was performed in the study. The responses in all interview forms were tabulated under common codes in a way to form categories (themes). The most remarkable results of the study were that school administrators indicated that distance education during the COVID-19 pandemic process generally had positive and negative aspects. Furthermore, the situations such as Internet access, lack of technical infrastructure, and computer/tablet shortage were the most determined problems during the pandemic.

Integration of e-learning and computerized assessments into many levels of educational programs has been increasing as digital technology progresses. Due to handful of prominent advantages of computer-based-testing (CBT), a rapid transition in test administration mode from paper-based-testing (PBT) to CBT has been emerged. Recently, many national and international testing agencies have been offering electronic version of some low- and high-stake tests along with their paper versions. In this study, we aim to examine test administration mode effect from a standpoint of cognitive effort exertion. To this end, the results of this experimental study suggest that the cognitive effort exertion rates of CBT and PBT examinees are different. More specifically, the study results suggest empirical evidence that examinees exert higher cognitive effort in a CBT in comparison to its PBT counterpart.

Objective: to determine the effects of physical activity on quality of life among female undergraduate students. Material & Methods: A randomized clinical trial was conducted on n=52 female students, after taking approval from higher authorities of the Bilquis Postgraduate College for Women PAF Nur Khan Base Rawalpindi, The inactive female students >1monthbetween 18-25 years were included in the study. The participants were randomly divided into three groups, such as Light Physical Activity (LPA), Moderate Physical Activity (MPA) and Vigorous Physical activity (VPA) group. The short form (SF-36) was used to observe Quality of Life (QOL), among participant at baseline and after six weeks of intervention. The One Way ANOVA with Tukey HSD post hoc was applied on mean differences for comparison. The clinical significance eta squared (η2) was used. Results: The result showed that Role limitation (mental) was significantly improved in vigorous activity group than the light (MD=21.20, d=0.85, 95% CI=0.97 to 43.37) and moderate (MD=23.94, d=0.96 95% CI=4.05 to 43.83) activity group. While social function showed significant improvement in moderate activity group as compared to light (MD=15.30, d=1.01, 95% CI=3.83 to 26.76) activity and vigorous (MD=9.60, d=0.63, 95% CI=1.68 to 20.88) activity group. The pain also showed significant improvement in moderate activity as compared to light (MD=20.32, d=1.09, 95% CI=5.48 to 35.16) and vigorous (MD=21.97, d=1.18, 95% CI=9.67 to 34.26) activity group.

Mô hình Pendubot là mô hình có ngõ vào điều khiển ít hơn số bậc tự do, có độ phi tuyến cao và rất khó để điều khiển. Pendubot với cấu trúc cơ khí không quá phức tạp nên được nhiều nhà nghiên cứu sử dụng để kiểm tra giải thuật điều khiển trong các phòng thí nghiệm. Trong bài báo này, tác giả sử dụng giải thuật toàn phương tuyến tính dựa trên logic mờ (Fuzzy Linear Quadratic Regulator) để giải quyết bài toán cân bằng tại vị trí TOP của mô hình Pendubot. Ý tưởng chính của phương pháp này là sử dụng giải thuật mờ kết hợp với giải thuật di truyền để lựa chọn thông số điều khiển cho bộ điều khiển tuyến tính bậc hai (Linear Quadratic Regulator). Thông qua mô phỏng trên Matlab/Simulink và thực nghiệm điều khiển tại vị trí TOP với thanh 1 và thanh 2 lần lượt tại 90 độ và 0 độ.
