Establishing Governance for Hybrid Cloud and the Internet of Things
Authors: Wolfe Martin
Published: October 2016

This chapter is focused on the current and future state of operating a Hybrid Cloud or Internet of Things (IoT) environment. This includes tools, data, and processes which allow an organization to use these assets to serve business goals. Examining governance in this context shows how it works today and how it should change, using some real-world examples to show the impacts and advantages of these changes. It is a high level overview of those important topics with prescriptive detail left for a future and follow-on analysis. Finally, all of the lessons learned, when combined together form a governance fabric, resulting in a set of techniques and actions which tie together into a supporting framework and set of processes. The important questions include: Why does governance matter in the deployment and operation of Hybrid Cloud and IoT? If governance already exists how must it change? What are the important and salient characteristics of governance which need special focus? Thus, this analysis gives a context of how today's governance approach should change when moving to a Hybrid Cloud or IoT model.
The Origins of International Rankings
Authors: O'Leary John
Published: October 2016

The chapter traces the development of international rankings of universities from their domestic predecessors in the United States and United Kingdom in particular. It soon became clear that different measures were required because of the scarcity of data collected on the same basis worldwide. This remains their overriding challenge, particularly where teaching quality is concerned. It is also why the best-read rankings – those published by QS, the Shanghai Rankings Consultancy and Times Higher Education – are based primarily on research quality. The process has become more sophisticated since the first international rankings appeared in 2003 and 2004, with a much wider variety of users than the early compilers expected, but they are unlikely ever to satisfy critics in the academic world.
Analyzing the Disciplinary Focus of Universities
Authors: Robinson-Garcia Nicolas , Jiménez-Contreras Evaristo
Published: October 2016

The phenomenon of rankings is intimately related with government interest in fiscalizing the research outputs of universities. New forms of managerialism have been introduced into the higher education system, leading to an increasing interest from funding bodies in developing external evaluation tools to allocate funds. Rankings rely heavily on bibliometric indicators. But, bibliometricians have been very critical with their use. Among other, they have pointed out the over-simplistic view rankings represent when analyzing the research output of universities, as they consider them as homogeneous ignoring disciplinary differences. Although many university rankings now include league tables by fields, reducing the complex framework of universities' research activity to a single dimension leads to poor judgment and decision making. This is partly because of the influence disciplinary specialization has on research evaluation. This chapter analyzes from a methodological perspective how rankings suppress disciplinary differences which are key factors to interpret correctly these rankings.
Overcoming Size and Subject Bias in Rankings
Authors: Pratt Simon Michael
Published: October 2016

Although it is impossible to distill the complexity of a university down to a single ranking position that represents the multiple missions of a university or the different stakeholders of ranking user, rankings are here to stay. It is essential that rankings publishers are clear about their objectives and use techniques to overcome bias. This paper discusses in detail some of the trends and bias found in data used in rankings and methods that can be used to overcome bias. It also discusses the motivations behind rankings and the influence of institution size on ranking outcome.
Building a World-Class University and the Role of University Ranking
Authors: Khomyakov Maxim B.
Published: October 2016

The chapter is devoted to the analysis of the impact of the global academic rankings and the concept of world-class university upon the system of high education both globally and in contemporary Russia. The author analyses the use of the rankings in benchmarking and strategy planning, and demonstrates negative influence of the obsession with the rankings in some countries. The chapter considers the case of the strategy of Ural Federal University (Russia) as one of the examples of both use and abuse of the rankings in large regional Russian university. The author argues for the necessity of organizing transnational associations and consortia of the universities, especially in emerging countries (BRICS nations, for example), to resist neo-Imperial features of today's global Academia. One of the remedies the chapter proposes is to adopt the idea of plural modernities from sociology and to treat global education environment as kind of a multi-polar world. Then, the author argues, the rankings should be supplemented with qualitative comparative analysis of educational systems.
Assembly, Space, and Things
Authors: Speranza Philip , Germany Jason O.
Published: October 2016

Each day as one notices more people walking along sidewalks, head down peering into smart phones, the fear is that social interaction in public space is dead. However, the integration of human and non-human processes may connect our communities now in more ways than ever before. New urban design theory suggests that “the city” may not be understood as a whole, rather as an assembly of dynamic urban processes. At many bike share systems around the world only static maps with limited interaction experience. Urban interaction design and the Internet of Things, is changing this experience. The interdisciplinary methodology describes a symbiosis of people, space and things. The significance is the integrated urban interaction design process of: urban design theory using classification of urban experience; geospatial analysis at the street-scale of point addresses, and fabrication of a test-bed kiosk to test ambient sensors and user interaction. Connectivity experienced in the virtual space of social media may now enter back into the physical realm of public space.

Published: October 2016

The increasing use of technologies like smart phones and mobile apps enables people to be actively involved in collecting data that can be the base of useful services to the whole citizenship. In the realm of volunteer data collection, this chapter addresses the problem of mobility and accessibility limitations for vulnerable citizens in today's cities. The MEP (Maps for Easy Paths) project proposes a set of tools and mobile apps for the enrichment of geographical maps with information about accessibility of urban pedestrian pathways, targeted at people with mobility problems. Different issues are considered and discussed in this chapter, including: the problem of collecting data of a user's route and of reconstructing it with novel sensor fusion techniques; the problem of correcting the positions obtained from low-cost GNSS receivers of mobile devices; the need of usable and accessible applications for the fruition of the collected data suitable for the target users.
Design and Development of Sentient Collective Urban Spaces
Authors: Pak Burak
Published: October 2016

This chapter aims to envision design approaches for creating ubiquitous interactive spaces which can empower the users to shape and reshape their living environments. It starts with the discussion of the affordances of networked sentient technologies to facilitate cycles of reflexivity through a comparative case study. Based on this analysis, the author distils key principles for future practices including: incomplete, dynamic architectural program, continuous representation of the user needs, incorporation of user variety and differences, embracing open-endedness, self-organization and spontaneity in use. Following these principles, the author reveals a conceptual design for a sentient space in Ghent as a means to demonstrate action possibilities latent in ubiquitous spaces. In conclusion, the author shares lessons learned and elaborates on future directions.
Consider Four Types of Online Identities for Teaching and Modeling Online Behavior
Authors: Koh-Herlong L. , Brown Abbie
Published: October 2016

The purpose of this chapter is to provide data and suggestions to educators for teaching and modeling concepts and practices related to online identity. The capabilities introduced by Web 2.0 have changed the potential benefits and liabilities of using online identities. Because online identities can be different from a person's real, offline self, approaches for teaching online self-presentation will differ from the traditional methods of teaching about social interaction. The authors present two theoretical foundations to frame the concept of online self. After a discussion of issues and problems associated with online identities, the authors apply the findings from a recent study to help educators model and teach about online identities. The primary findings are the identification of four types of online identities that include real, desired, enhanced, and deceptive. The chapter concludes with recommendations for future studies to further this topic and extend the current research.
Developing an Understanding of Cyberbullying
Authors: Walker Carol M.
Published: October 2016

When considering ethical practice for educators in the 21st Century it is imperative that teacher educators, school counselors, and administration are knowledgeable in all aspects of bullying via technology that youth and young adults are experiencing on school campuses throughout the country. The exponential proliferation of technology and social media has brought traditional bullying into cyberspace. The purpose of this chapter is to enhance the reader's understanding of the incidents of cyberbullying, to provide knowledge of the challenges researchers face in operationalizing cyberbullying that will enable all professionals to assist victims, and to proffer techniques that may be implemented in the ethical practice of primary, secondary, or college educators as they work with Millennials and Neo-millennials in the 21st Century classroom.
2D and 3D Visual Attention for Computer Vision
Authors: Ricordel Vincent , Wang Junle , Da Silva Matthieu Perreira , Le Callet Patrick
Published: October 2016

Visual attention is one of the most important mechanisms deployed in the human visual system (HVS) to reduce the amount of information that our brain needs to process. An increasing amount of efforts has been dedicated to the study of visual attention, and this chapter proposes to clarify the advances achieved in computational modeling of visual attention. First the concepts of visual attention, including the links between visual salience and visual importance, are detailed. The main characteristics of the HVS involved in the process of visual perception are also explained. Next we focus on eye-tracking, because of its role in the evaluation of the performance of the models. A complete state of the art in computational modeling of visual attention is then presented. The research works that extend some visual attention models to 3D by taking into account of the impact of depth perception are finally explained and compared.
Integration of Legal Aspects in 3D Cadastral Systems
Authors: El-Mekawy Mohamed Sobaih Aly , Paasch Jesper M. , Paulsson Jenny
Published: October 2016

This article continues a research on the feasibility of BIM for 3D cadastre in unified building models, presented in . It describes problems and solutions concerning interaction between BIM and the registration and visualisation of legal 3D property information. BIM and legal 3D property are two seemingly different domains, and there is a lack of BIM-3D property research in relation to technical and registration issues. The article therefore focuses on possibilities and difficulties of addressing legal interests (i.e. rights, restrictions and responsibilities) in land. A Swedish case study is used to describe the use of 3D property formation and registration in Sweden, and how it might be possible to achieve a more integrated, standard based registration of legal boundaries and physical buildings. The results emphasize how BIM and 3D property domains can interact to serve the needs for effective information handling by e.g. importing 3D cadastral boundaries into BIM as basis for decision-making or to use BIM as input in the 3D cadastral formation process.
Laser Metal Deposition Process
Authors: Mahamood Rasheedat M.
Published: October 2016

Laser metal deposition process belongs to the directed energy deposition class of additive manufacturing process that is capable of producing highly complex part directly from the three dimensional (3D) computer aided design file of the component by adding materials layer after layers. Laser metal deposition process is a very important additive manufacturing process and it is the only class of additive manufacturing process that can be used to repair valued component parts which were not repairable in the past. Also because this additive manufacturing process can handle multiple materials simultaneously, it is used to produce part with functionally graded material. Some of the features of the laser metal deposition process are described in this chapter. Some experimental studies on the laser metal deposition of Titanium alloy- composite are also presented.
Towards ProGesture, a Tool Supporting Early Prototyping of 3D-Gesture Interaction
Authors: Bomsdorf Birgit , Blum Rainer , Künkel Daniel
Published: October 2016

Development of gesture interaction requires a combination of three design matters: gesture, presentation, and dialog. However, in current work on rapid prototyping the focus is on gestures taking into account only the presentation. Model-based development incorporating gestures, in contrast, supports the gesture and dialog dimensions. The work on ProGesture aims at a rapid prototyping tool supporting a coherent development within the whole gesture-presentation-dialog design space. In this contribution, a first version of ProGesture is introduced. Here, gestures are specified by demonstrating the movements or they are composed of other gestures. The tool also provides a dialog editor, which allows gestures to be assigned to dialog models. Based on its executable runtime system the models and gestures can be tested and evaluated. In addition, gestures can be bound to first presentations or existing applications and evaluated in their context.

Authors: Bacil Eliane Denise Araújo , Piola Thiago Silva , Watanabe Priscila Iumi , Da Silva Michael Pereira , Legnani Rosimeide Francisco Santos , De Campos Wagner
Published: October 2016

Este estudo tem como objetivo analisar a associação entre maturação biológica e comportamento sedentário em crianças e adolescentes. Realizou-se uma revisão sistemática em maio de 2015 nos bancos de periódicos eletrônicos da PubMed/MEDLINE, SportDiscus, Web of Science e LILACS, sem restrição de período de tempo. Foram identificados 294 artigos potencialmente relevantes e sete preencheram os critérios de inclusão. Foi possível identificar uma associação direta entre comportamento sedentário e tempo da maturação biológica. O comportamento sedentário parece aumentar com o avançar da idade cronológica e biológica em ambos os sexos. No que se refere a relação entre comportamento sedentário e timing da maturação biológica, os escolares de ambos os sexos maturados precocemente apresentaram maior comportamento sedentário. No entanto, em alguns estudos esta relação varia entre os sexos. A maturação biológica parece contribuir para o aumento do comportamento sedentário em crianças e adolescentes.Palavras-chave: Puberdade. Estilo de vida sedentário. Estudantes.

A palynological analysis of middle Cretaceous strata in the Hume River section, Northwest Territories, Canada
Authors: Fensome R A
Published: October 2016

The Hume River section northwest of the town of Norman Wells, Northwest Territories consists of a 2-km-thick succession of Cretaceous strata deposited in a foreland basin ahead of the advancing Mackenzie Mountains thrust-and-fold belt. Rocks in the section have
been assigned (from bottom to top) to the Martin House, Arctic Red, Slater River and Trevor formations. The Martin House Formation rest unconformably on Paleozoic strata, and an unconformity separates the Arctic Red and Slater River formations. In terms of paleoenvironments, the section represents
fluctuating fully marine to non-marine deposits near the margin of the Western Interior Seaway. Previous age determinations have encompassed an Aptian to Turonian age range for the section as a whole. My analyses indicate an early to middle Albian age for the Martin House Formation, a middle to late
Albian age for Arctic Red Formation (which accords with a late Albian U-Pb radiometric date for the unit), a late Albian age for the lowest part of the Slater River Formation (in contrast to Cenomanian age determined by the most recent foraminiferal analyses), and a Cenomanian or younger age for the
upper part of the Slater River Formation and for the Trevor Formation. I found no conclusive evidence for an age younger than Cenomanian. The Albian-Cenomanian boundary may be within the basal part of the Slater River Formation rather than at the unconformity between that formation and the
underlying Arctic Red Formation. Interesting parallels can be drawn with lithological units and dinocyst assemblages in other parts of the Western Interior Basin, notably in northern Alberta. Perhaps there too, the Albian-Cenomanian boundary is within the basal part of the Fish Scales Marker Bed
(equivalent to the Slater River Formation) rather than at its base.
More than Just a Break from Treatment: How Substance Use Disorder Patients Experience the Stable Environment in Horse-Assisted Therapy
Authors: Kern-Godal Ann , Brenna Ida Halvorsen , Arnevik Espen Ajo , Ravndal Edle
Published: October 2016

Inclusion of horse-assisted therapy (HAT) in substance use disorder (SUD) treatment is rarely reported. Our previous studies show improved treatment retention and the importance of the patient–horse relationship. This qualitative study used thematic analysis, within a social constructionist framework, to explore how eight patients experienced contextual aspects of HAT's contribution to their SUD treatment. Participants described HAT as a “break from usual treatment”. However, four interrelated aspects of this experience, namely “change of focus”, “activity”, “identity”, and “motivation,” suggest HAT is more than just a break from usual SUD treatment. The stable environment is portrayed as a context where participants could construct a positive self: one which is useful, responsible, and accepted; more fundamentally, a different self from the “patient/self” receiving treatment for a problem. The implications extend well beyond animal-assisted or other adjunct therapies. Their relevance to broader SUD policy and treatment practices warrants further study.
Wedge Operations and Torus Symmetries II
Authors: Choi Suyoung , Park Hanchul
Published: October 2016

A fundamental idea in toric topology is that classes of manifolds with well-behaved torus actions (simply, toric spaces) are classified by pairs of simplicial complexes and (non-singular) characteristic maps. In a previous paper, the authors provided a new way to find all characteristic maps on a simplicial complex K(J) obtainable by a sequence of wedgings from K.The main idea was that characteristic maps on K theoretically determine all possible characteristic maps on a wedge of K.

We further develop our previous work for classification of toric spaces. For a star-shaped simplicial sphere K of dimension n-1 with m vertices, the Picard number Pic(K) of K is m-n. We call K a seed if K cannot be obtained by wedgings. First, we show that for a fixed positive integer 𝓁, there are at most finitely many seeds of Picard 𝓁 number supporting characteristic maps. As a corollary, the conjecture proposed by V. V. Batyrev in is solved affirmatively.

Secondly, we investigate a systematicmethod to find all characteristic maps on K(J) using combinatorial objects called (realizable) puzzles that only depend on a seed K. These two facts lead to a practical way to classify the toric spaces of fixed Picard number.

Published: October 2016

La violencia sobre las mujeres se produce no solo en situaciones de conflicto armado o de desastre natural sino que está presente en contextos normalizados. Específicamente está presente en el ámbito laboral, tanto de manera manifiesta como simbólica y siempre con consecuencias psicosociales  devastadoras. Método: Este trabajo examina, a través de un análisis de contenido de dos diarios especializados y de entrevistas en profundidad a once directivas y a dieciséis directivos, la imagen social de las mujeres que se emplean en el sector de la construcción y la propia imagen que ellas tienen sobre sí mismas. Resultados y conclusiones: La proyección de directivas que trabajan en la construcción en los diarios especializados es inexistente. El análisis de su autoimagen sugiere que no perciben barreras de género en su acceso y ascenso laboral. Hay que incidir sobre la imagen que proyectan los medios sobre las autopercepciones para luchar contra las discriminaciones.
Developing Emotional Intelligence in the Clinical Learning Environment: A Case Study in Cultural Transformation
Authors: Cohen-Katz Joanne , Sternlieb Jeffrey L. , Hansen Susan E. , Dostal Julie A.
Published: October 2016

Background 

Burnout continues to erode the physician workforce, and there are few effective intervention studies to guide educators.

Objective 

We explored residents' experience in a model environment emphasizing resident wellness, safety, and interpersonal skills.

Methods 

As 1 of 14 participants in the national Preparing the Personal Physician for Practice (P4) project, the family medicine residency at Lehigh Valley Health Network implemented a series of curricular changes designed to transform the culture of education. This mixed-methods case study utilizes the results from 3 quantitative self-report instruments for well-being, along with content analysis of transcripts from 20 focus groups and 33 resident advising sessions to describe experiences of the residents enrolled between July 2007 and June 2012.

Results 

In the intervention, we found no statistically significant quantitative differences in the well-being of residents compared with the family medicine faculty and staff. Deductive (a priori and template) analysis and inductive thematic analysis of the residents' articulations of their experiences revealed 6 recurrent themes: naming/articulation of emotions, relationships, attitudes about self-care, self-reflection, delivery of learning experiences, and availability of resources.

Conclusions 

Quantitative measures of well-being did not capture the experiential value of the curricular innovations implemented by the residency program, while qualitative analysis highlighted themes important to residents. While not all residents in the intervention expressed support for the changes, repeated references to the nurturing educational environment indicate recognition of, and favorable responses to, the creation of an emotionally intelligent learning community.
Proof of concept for turbulence measurements with the RPAS SUMO during the BLLAST campaign
Authors: Båserud Line , Reuder Joachim , Jonassen Marius O. , Kral Stephan T. , Paskyabi Mostafa B. , Lothon Marie
Published: October 2016

Abstract. The micro-RPAS (remotely piloted aircraft system) SUMO (Small Unmanned Meteorological Observer) equipped with a five-hole-probe (5HP) system for turbulent flow measurements was operated in 49 flight missions during the BLLAST (Boundary-Layer Late Afternoon and Sunset Turbulence) field campaign in 2011. Based on data sets from these flights, we investigate the potential and limitations of airborne velocity variance and TKE (turbulent kinetic energy) estimations by an RPAS with a take-off weight below 1 kg. The integration of the turbulence probe in the SUMO system was still in an early prototype stage during this campaign, and therefore extensive post-processing of the data was required. In order to be able to calculate the three-dimensional wind vector, flow probe measurements were first synchronized with the autopilot's attitude and velocity data. Clearly visible oscillations were detected in the resulting vertical velocity, w, even after correcting for the aircraft motion. The oscillations in w were identified as the result of an internal time shift between the inertial measurement unit (IMU) and the GPS sensors, leading to insufficient motion correction, especially for the vertical wind component, causing large values of σw. Shifting the IMU 1–1.5 s forward in time with respect to the GPS yields a minimum for σw and maximum covariance between the IMU pitch angle and the GPS climb angle. The SUMO data show a good agreement to sonic anemometer data from a 60 m tower for σu, but show slightly higher values for σv and σw. Vertical TKE profiles, obtained from consecutive flight legs at different altitudes, show reasonable results, both with respect to the overall TKE level and the temporal variation. A thorough discussion of the methods used and the identified uncertainties and limitations of the system for turbulence measurements is included and should help the developers and users of other systems with similar problems.
Surface complexation modeling of Cd(II) sorption to montmorillonite,
bacteria, and their composite
Authors: Wang Ning , Du Huihui , Huang Qiaoyun , Cai Peng , Rong Xingmin , Feng Xionghan , Chen Wenli
Published: October 2016

Abstract. Surface complexation modeling (SCM) has emerged as a powerful tool for simulating heavy metal adsorption processes on the surface of soil solid components under different geochemical conditions. The component additivity (CA) approach is one of the strategies that have been widely used in multicomponent systems. In this study, potentiometric titration, isothermal adsorption, zeta potential measurement, and extended X-ray absorption fine-structure (EXAFS) spectra analysis were conducted to investigate Cd adsorption on 2 : 1 clay mineral montmorillonite, on Gram-positive bacteria Bacillus subtilis, and their mineral–organic composite. We developed constant capacitance models of Cd adsorption on montmorillonite, bacterial cells, and mineral–organic composite. The adsorption behavior of Cd on the surface of the composite was well explained by CA-SCM. Some deviations were observed from the model simulations at pH < 5, where the values predicted by the model were lower than the experimental results. The Cd complexes of X2Cd, SOCd+, R-COOCd+, and R-POCd+ were the predominant species on the composite surface over the pH range of 3 to 8. The distribution ratio of the adsorbed Cd between montmorillonite and bacterial fractions in the composite as predicted by CA-SCM closely coincided with the estimated value of EXAFS at pH 6. The model could be useful for the prediction of heavy metal distribution at the interface of multicomponents and their risk evaluation in soils and associated environments.
Prediction of biopore- and matrix-dominated flow from X-ray CT-derived
macropore network characteristics

Published: October 2016

Abstract. Prediction and modeling of localized flow processes in macropores is of crucial importance for sustaining both soil and water quality. However, currently there are no reliable means to predict preferential flow due to its inherently large spatial variability. The aim of this study was to investigate the predictive performance of previously developed empirical models for both water and air flow and to explore the potential applicability of X-ray computed tomography (CT)-derived macropore network characteristics. For this purpose, 65 cylindrical soil columns (6 cm diameter and 3.5 cm height) were extracted from the topsoil (5 cm to 8.5 cm depth) in a 15 m  ×  15 m grid from an agricultural field located in Silstrup, Denmark. All soil columns were scanned with an industrial X-ray CT scanner (129 µm resolution) and later employed for measurement of saturated hydraulic conductivity, air permeability at −30 and −100 cm matric potential, and gas diffusivity at −30 and −100 cm matric potential. Distribution maps for saturated hydraulic conductivity, air permeability, and gas diffusivity reflected no autocorrelation irrespective of soil texture and organic matter content. Existing empirical predictive models for saturated hydraulic conductivity and air permeability showed poor performance, as they were not able to realistically capture macropore flow. The tested empirical model for gas diffusivity predicted measurements at −100 cm matric potential reasonably well, but failed at −30 cm matric potential, particularly for soil columns with biopore-dominated flow. X-ray CT-derived macroporosity matched the measured air-filled porosity at −30 cm matric potential well. Many of the CT-derived macropore network characteristics were strongly interrelated. Most of the macropore network characteristics were also significantly correlated with saturated hydraulic conductivity, air permeability, and gas diffusivity. The predictive Ahuja et al. (1984) model for saturated hydraulic conductivity, air permeability, and gas diffusivity performed reasonably well when parameterized with novel, X-ray CT-derived parameters such as effective percolating macroporosity for biopore-dominated flow and total macroporosity for matrix-dominated flow. The obtained results further indicate that it is crucially important to discern between matrix-dominated and biopore-dominated flow for accurate prediction of macropore flow from X-ray CT-derived macropore network characteristics.
Short-to-medium range hydrologic forecast to manage water and
agricultural resources in India
Authors: Shah Reepal , Sahai Atul Kumar , Mishra Vimal
Published: October 2016

Abstract. Water resources and agriculture are often affected by the weather anomalies in India resulting in a disproportionate damage. While short to medium range prediction systems and forecast products are available, a skilful hydrologic forecast of runoff and root-zone soil moisture that can provide timely information has been lacking in India. Using precipitation and air temperature forecasts from the Climate Forecast System v2 (CFSv2), Global Ensemble Forecast System (GEFSv2) and four products from Indian Institute of Tropical Meteorology (IITM), here we show that the IITM ensemble mean (mean of all four products from IITM) can be used operationally to provide hydrologic forecast in India at 7–45 days lead time. The IITM ensemble mean forecast was further improved using bias correction for precipitation and air temperature. Forecast based on the IITM-ensemble mean showed better skill in majority of India for all the lead times (7–45 days) in comparison to the other forecast products. Moreover, the VIC simulated forecast of runoff and soil moisture successfully captured the observed anomalies during the severe droughts years. The findings reported herein have strong implications for providing timely information that can help farmers and water managers in decision making in India.

Abstract. The use of Unmanned Aerial Vehicles (UAVs) for surveying is now widespread and operational for several applications – quarry monitoring, archeological site surveys, forest management and 3D modeling for buildings, for instance. UAV is increasingly used by land surveyors especially for those kinds of projects. It is still ambiguous whether UAV can be applicable for smaller sites and property division. Therefore, the objective of this research is to extract a vectorized plan utilizing a UAV for a small site and investigate the possibility of an official land surveyor exploiting and certificating it. To do that, two plans were created, one using a UAV and another utilizing classical land surveyor instruments (Total Station). A comparison was conducted between the two plans to evaluate the accuracy of the UAV technique compared to the classical one. Moreover, other parameters were also considered such as execution time and the surface covered. The main problems associated with using a UAV are the level of precision and the visualization of the whole area. The results indicated that the precision is quite satisfactory with a maximum error of 1.0 cm on ground control points, and 4 cm for the rest of the model. On the other hand, the results showed that it is not possible to represent the whole area of interest utilizing a UAV, due to vegetation.
3D WEIGHT MATRICES IN MODELING REAL ESTATE PRICES

Abstract. Central role in spatial econometric models of real estate data has the definition of the weight matrix by which we capture the spatial dependence between the observations. The weight matrices presented in literature so far, treats space in a two dimensional manner leaving out the effect of the third dimension or in our case the difference in height where the property resides. To overcome this, we propose a new definition of the weight matrix including the third dimensional effect by using the Hadamard product. The results illustrated that the level effect can be absorbed into the new weight matrix.
GLOBAL REGISTRATION OF KINECT POINT CLOUDS USING AUGMENTED EXTENDED INFORMATION FILTER AND MULTIPLE FEATURES
Authors: Kang Z. , Chang M.
Published: October 2016

Abstract. Because the Infra-Red (IR) Kinect sensor only provides accurate depths up to 5 m for a limited field of view (60°), the problem of registration error accumulation becomes inevitable in indoor mapping. Therefore, in this paper, a global registration method is proposed based on augmented extended Information Filter (AEIF). The point cloud registration is regarded as a stochastic system so that AEIF is used to produces the accurate estimates of rigid transformation parameters through eliminating the error accumulation suffered by the pair-wise registration. Moreover, because the indoor scene normally contains planar primitives, they can be employed to control the registration of multiple scans. Therefore, the planar primitives are first fitted based on optimized BaySAC algorithm and simplification algorithm preserving the feature points. Besides the constraint of corresponding points, we then derive the plane normal vector constraint as an additional observation model of AEIF to optimize the registration parameters between each pair of adjacent scans. The proposed approach is tested on point clouds acquired by a Kinect camera from an indoor environment. The experimental results show that our proposed algorithm is proven to be capable of improving the accuracy of multiple scans aligning by 90%.

Abstract. In this work an Observing System Simulation Experiment (OSSE) approach is used to investigate the Argo array spatial sampling necessary in the Mediterranean Sea to recover the mesoscale signal as seen by altimetry. The monitoring of the mesoscale features is not an initial objective of the Argo network. However, it is an interesting question in the perspective of future network extensions in order to improve the ocean state estimates. A quality assessment of the performances of the altimeter product is carried out to quantify the differences between Argo and altimetry needed to conduct the simulation experiments. The method used here to evaluate the altimeter data is based on the comparison of Sea Level Anomalies (SLA) from altimetry and Dynamic Height Anomalies (DHA) referred to both 400 and 900 dbar computed from the in-situ Argo network. A standard deviation of the differences between SLA and DHA of 4.92 cm is obtained when comparing altimetry and Argo data referred to 400 dbar. The simulation experiments show that a configuration similar to the current Argo array in the Mediterranean (with a spatial resolution of 2° × 2°) is only able to recover the large-scale signals of the basin. On the contrary, the SLA field reconstructed from a 0.75° x 0.75° Argo network can retrieve most of the mesoscale signal. Such an Argo array of around 450 floats in the Mediterranean Sea would be enough to recover the SLA field with an RMSE of 3 cm for spatial scales higher than 150 km, similar to those captured by the altimetry.

Estudo transversal realizado em hospital de referência em urgência com amostragem por conveniência cujos dados foram coletados de junho a julho de 2014. Objetivou analisar os acidentes domésticos em idosos atendidos em hospital público de urgência. Do total de 83 entrevistados, 77,1% eram mulheres, possuíam 80 a 89 anos (32,5%), analfabetos (32,5%), viúvos (44,6%), residindo com cônjuge e outros familiares (73,5%), aposentados (84,4%), recebiam um a dois salários mínimos (88%). A prevalência de acidentes domésticos foi de 6,4%, com predominância de queda (84,4%), da própria altura (55,6%). Descuido na observação do ambiente foi auto referido como principal causa (45,8%). A não associação entre a ocorrência de quedas, existência de doença crônica, medicação de uso contínuo e realização de atividade no instante do acidente foi um achado relevante. Recomenda-se cuidado multiprofissional com avaliação funcional ampla identificando as deficiências dos idosos e limitações ambientais visando orientação comunitária e planejamento de intervenções integradas.

Published: October 2016

The present study objective was identifying mechanisms of response to water deficit of paricá seedlings. The experiment was conducted in a greenhouse, in 8-liter pots, with substrate consisting of soil (dystrophic Red-Yellow Latosol), in randomized block design, with five different irrigations based on the evapotranspiration of the plants (20, 40, 60, 80 and 100%), with six replications. The plants were irrigated daily, with a water volume corresponding to 100% of the evapotranspired water, and, at 90 days after germination, subjected to ten days of water deficit, after that irrigated during ten days with the different percentages of evapotranspiration, then evaluated. The following variables were measured: number of leaves (NL), plant height (PH), stem diameter (SD), total biomass (TB), total daily transpiration (TDT), total chlorophyll (TC), carotenoids (CAR), root mass ratio (RMR), leaf mass ratio (LMR) stem mass ratio (SMR). Concluded that paricá seedlings response to water deficit with slowing down of dehydration, with reduction of content of carotenoids and increase in root volume. As a consequence of water stress, they reduce the number of leaves, stem diameter, plant height, and, of course, total biomass, aiming at maintaining the internal water, indicating low ability to tolerate stress.

Published: October 2016

O objetivo desse artigo foi, ao gerar informações econômicas sobre a atividade de reflorestamento com Eucalipto spp, no estado do Acre, subsidiar a formulação de políticas públicas voltadas à utilização dos recursos florestais locais. Em termos específicos, essa pesquisa visou: (a) identificar os custos relacionados à implantação e manutenção de povoamentos de eucalipto na região do Baixo Acre; (b) quantificar as receitas da atividade de reflorestamento nessa região e (c) avaliar a viabilidade econômica de povoamentos florestais na região. O método utilizado identificou o valor presente líquido (VPL), a taxa interna de retorno (TIR) e o valor esperado da terra (VET), válidos para os povoamentos com eucalipto nessa região. Dos resultados gerados pode-se inferir que: (a) os projetos analisados apresentaram um elevado custo de implantação e manutenção quando comparados com os custos encontrados em outros estudos; (b) os reflorestamentos avaliados geraram uma renda menor que as obtidas em projetos similares implantados em outras regiões do Brasil e (c) os povoamentos pesquisados demonstram que, nas condições propostas, produzir eucalipto para atender à geração de energia em Rio Branco não oferece viabilidade superior ao custo de oportunidade do capital, indicando assim a inviabilidade econômica dessa atividade.
