A Spectral Unmixing Method by Maximum Margin Criterion and Derivative Weights to Address Spectral Variability in Hyperspectral Imagery
Authors: Shao Yang , Lan Jinhui
Published: May 2019

Limited to the low spatial resolution of the hyperspectral imaging sensor, mixed pixels are inevitable in hyperspectral images. Therefore, to obtain the endmembers and corresponding fractions in mixed pixels, hyperspectral unmixing becomes a hot spot in the field of remote sensing. Endmember spectral variability (ESV), which is common in hyperspectral images, affects spectral unmixing accuracy. This paper proposes a spectral unmixing method based on maximum margin criterion and derivative weights (MDWSU) to reduce the effect of ESV on spectral unmixing. Firstly, in the MDWSU model, an effective and fast algorithm is employed for establishing the endmember spectral library. Then a spectral weighting matrix based on the maximum margin criterion is constructed based on the endmember spectral library. Besides, derivative analysis and local neighborhood weights are merged into local neighborhood derivative weights, which act as a regularization term to penalize different abundance vectors. Local neighborhood derivative weights and spectral weighting matrix are proved to reduce the effect of ESV. Real hyperspectral data experiments show that the MDWSU model can obtain more accurate endmembers and abundance estimation. In addition, the experimental results, including the spectral angle distance and the root mean square error, prove the superiority of the MDWSU model over the previous methods.
Evaluating Impact of Rain Attenuation on Space-borne GNSS Reflectometry Wind Speeds
Authors: Asgarimehr Milad , Wickert Jens , Reich Sebastian
Published: May 2019

The novel space-borne Global Navigation Satellite System Reflectometry (GNSS-R) technique has recently shown promise in monitoring the ocean state and surface wind speed with high spatial coverage and unprecedented sampling rate. The L-band signals of GNSS are structurally able to provide a higher quality of observations from areas covered by dense clouds and under intense precipitation, compared to those signals at higher frequencies from conventional ocean scatterometers. As a result, studying the inner core of cyclones and improvement of severe weather forecasting and cyclone tracking have turned into the main objectives of GNSS-R satellite missions such as Cyclone Global Navigation Satellite System (CYGNSS). Nevertheless, the rain attenuation impact on GNSS-R wind speed products is not yet well documented. Evaluating the rain attenuation effects on this technique is significant since a small change in the GNSS-R can potentially cause a considerable bias in the resultant wind products at intense wind speeds. Based on both empirical evidence and theory, wind speed is inversely proportional to derived bistatic radar cross section with a natural logarithmic relation, which introduces high condition numbers (similar to ill-posed conditions) at the inversions to high wind speeds. This paper presents an evaluation of the rain signal attenuation impact on the bistatic radar cross section and the derived wind speed. This study is conducted simulating GNSS-R delay-Doppler maps at different rain rates and reflection geometries, considering that an empirical data analysis at extreme wind intensities and rain rates is impossible due to the insufficient number of observations from these severe conditions. Finally, the study demonstrates that at a wind speed of 30 m/s and incidence angle of 30°, rain at rates of 10, 15, and 20 mm/h might cause overestimation as large as ≈0.65 m/s (2%), 1.00 m/s (3%), and 1.3 m/s (4%), respectively, which are still smaller than the CYGNSS required uncertainty threshold. The simulations are conducted in a pessimistic condition (severe continuous rainfall below the freezing height and over the entire glistening zone) and the bias is expected to be smaller in size in real environments.
Airborne LIDAR-Derived Aboveground Biomass Estimates Using a Hierarchical Bayesian Approach

Published: May 2019

Conventional ground survey data are very accurate, but expensive. Airborne lidar data can reduce the costs and effort required to conduct large-scale forest surveys. It is critical to improve biomass estimation and evaluate carbon stock when we use lidar data. Bayesian methods integrate prior information about unknown parameters, reduce the parameter estimation uncertainty, and improve model performance. This study focused on predicting the independent tree aboveground biomass (AGB) with a hierarchical Bayesian model using airborne LIDAR data and comparing the hierarchical Bayesian model with classical methods (nonlinear mixed effect model, NLME). Firstly, we chose the best diameter at breast height (DBH) model from several widely used models through a hierarchical Bayesian method. Secondly, we used the DBH predictions together with the tree height (LH) and canopy projection area (CPA) derived by airborne lidar as independent variables to develop the AGB model through a hierarchical Bayesian method with parameter priors from the NLME method. We then compared the hierarchical Bayesian method with the NLME method. The results showed that the two methods performed similarly when pooling the data, while for small sample sizes, the Bayesian method was much better than the classical method. The results of this study imply that the Bayesian method has the potential to improve the estimations of both DBH and AGB using LIDAR data, which reduces costs compared with conventional measurements.

Published: May 2019

Can we build stable Climate Data Records (CDRs) spanning several satellite generations? This study outlines how the ClOud Fractional Cover dataset from METeosat First and Second Generation (COMET) of the EUMETSAT Satellite Application Facility on Climate Monitoring (CM SAF) was created for the 25-year period 1991–2015. Modern multi-spectral cloud detection algorithms cannot be used for historical Geostationary (GEO) sensors due to their limited spectral resolution. We document the innovation needed to create a retrieval algorithm from scratch to provide the required accuracy and stability over several decades. It builds on inter-calibrated radiances now available for historical GEO sensors. It uses spatio-temporal information and a robust clear-sky retrieval. The real strength of GEO observations—the diurnal cycle of reflectance and brightness temperature—is fully exploited instead of just accounting for single “imagery”. The commonly-used naive Bayesian classifier is extended with covariance information of cloud state and variability. The resulting cloud fractional cover CDR has a bias of 1% Mean Bias Error (MBE), a precision of 7% bias-corrected Root-Mean-Squared-Error (bcRMSE) for monthly means, and a decadal stability of 1%. Our experience can serve as motivation for CDR developers to explore novel concepts to exploit historical sensor data.

Authors: Ahn Ha-Eun , Jeong Jinwoo , Kim Je Woo
Published: May 2019

Visual quality and algorithm efficiency are two main interests in video frame interpolation. We propose a hybrid task-based convolutional neural network for fast and accurate frame interpolation of 4K videos. The proposed method synthesizes low-resolution frames, then reconstructs high-resolution frames in a coarse-to-fine fashion. We also propose edge loss, to preserve high-frequency information and make the synthesized frames look sharper. Experimental results show that the proposed method achieves state-of-the-art performance and performs 2.69x faster than the existing methods that are operable for 4K videos, while maintaining comparable visual and quantitative quality.

Published: May 2019

Water table contribution to plant water use is a significant element in improving water use efficiency (WUE) for agricultural water management. In this study, lysimeter experiments were conducted in a controlled greenhouse environment to investigate the response of soybean water uptake and growth parameters under four different water table depths (WTD) (30, 50, 70, and 90 cm). Soybean crop water use, WUE, and root distribution under the different WTD were examined. For 30, 50, 70, and 90 cm of WTD treatments, the average water table contributions were 89, 83, 79, and 72%; the grain yields were 15.1, 10.5, 14.1, and 17.2 g/lys.; and the WUEs were 0.22, 0.18, 0.25, and 0.31 g/lys./cm, respectively. Further analysis of the root mass and proportional distribution among the different soil layers illustrated that the lysimeters with 70 and 90 cm WTD had greater root mass with higher root distribution at 40–75 cm of the soil layer. The results indicated that 70 and 90 cm of constant WTD can yield higher grain yield and biomasses with greater WUE and better root distribution than the irrigated or shallow WTD treatments.
Stability of Rubble Mound Breakwaters—A Study of the Notional Permeability Factor, Based on Physical Model Tests
Authors: Eldrup Mads Røge , Lykke Andersen Thomas , Burcharth Hans Falk
Published: May 2019

The Van der Meer formulae for quarry rock armor stability are commonly used in breakwater design. The formulae describe the stability as a function of the wave characteristics, number of waves, front slope angle and rock material properties. The latter includes a so-called notional permeability factor characterizing the permeability of the structure. Based on armor stability model tests with three armor layer compositions, Van der Meer determined three values of the notional permeability. Based on numerical model results he added for a typical layer composition one more value. Based on physical model tests, the present paper provides notional permeability factors for seven layer compositions of which two correspond to the compositions tested by Van der Meer. The results of these two layer compositions are within the scatter of the results by Van der Meer. To help determination of the notional permeability for non-tested layer compositions, a simple empirical formula is presented.

Published: May 2019

In the seventies of the previous century, Dr. Zoltán Kováts set two directions in the research of mallows. One of the directions was the biotechnology of the mallow species and the other direction is using the mallow species as biomass material. In order to do this he brought mallow mother spawns of ornamental and biomass sorts from botanical gardens abroad and tested many of them, including the a Sida hermaphrodita kind. Fourty years later, for the second time this plant, known as the „energy mallow” got back to Hungary again, right into the sight of hungarian biomass business with the help of László Balogh and his associates using help from Poland. This genus got into the center of our research, because of it’s valuable attributes. The latest experiments are about using it as an energy plant, without examining genetic details. The plant grows up to morethan 3 meters, has high growing rate and produces big amount of green mass. We don’t have any hungarian data about whether the plant continues the sufficient growing rate or not, after cutting it back.We have to explore the potentials in the Sida’s sublimation. The plant is mostly suitable for ornamental and energy utilization, so further sublimation should be aiming for these aspects. During my research period, we are willing to get to know these potentials and the best possible use of them.

Anaerobe degradation of maize infected by Fusarium graminearum
Authors: Mézes Lili , Bíró György , Tamás János
Published: May 2019

Last year intense rainfalls and moisture conditions were beneficial for the Fusarium sp. in Hungary. Fusarium strains decrease cereal quality (for example maize), furthermore may cause yield loss. Due to the toxin production, the fungi have a dangerous animal and human pathogen effect (Placinta et al., 1999).The effects of the Fusarium infection and its mycotoxin production haven’t been perfectly eliminated. Fusariumgraminearumis the most common agricultural pathogen in Hungary. The utilization of infected maize as an alternative biogas raw material may be an efficient and environmentally friendly disposal method. In this case, Fusarium-, and mycotoxin-content of the maize have to be analyzed as well as the impact of these factors’ on the biogas production process. Our experience was based on the raw material basis of a biogas plant. Different amount of Fusarium free and infected maize grits have been added to the regular raw material mixture. The detection of Fusarium fungi has been analyzedin experimental digesters throughout the different stages of mesophilic digestion. In the biogas liquid end product the Fusarium was detected by breeding and by microscope. According to our results, the Fusarium sp. was not detectable in the liquid end product after 30 days.

Published: May 2019

It is vital to examine the strategic plans and leadership insights of the university, the faculties, the departments and the institutions in the research of the „third mission” of the universities. Because of the undertaken social-economic role in the region it is indispensable to know the turbulently changing environment (hazards – opportunities), to map the competencies available in the university (strengths – weaknesses) and to recognize the relations between the external and internal environment. It is an important factor to define the strategic directions of the departments, examining them in direction dimension (pro-active – adaptive) and in role dimension (top-down – bottom-up). The main objective of this research is to recognize the formal and informal strategic visions of the institutes and departments in the Centre for Agricultural and Applied Economic Sciences of the University of Debrecen, and to examine how these visions are related to the university's role in the regional innovation system.

Penelitian ini berfokus untuk merakam akselerasi sebagai akibat dari aktivitas fisik. Nilai akselerasi sebagai akibat dari suatu aktivitas memiliki pola tertentu sesuai dengan gerakan atau aktivitas yang dilakukan, pola dari akselerasi tersebut selanjutnya dapat diolah atau dikalkulasi untuk mengetahui jenis aktivitas yang dilakukan. Sebelum melakukan pengolahan data akselerasi maka diperlukan proses perekaman data, pada penelitian ini perekaman dilakukan dengan memasang perangkat wearable device pada pinggang sebelah kiri kemudian mengirimkan data tersebut ke komputer yang digunakan untuk merekam pola aktivitas. Wearable device yang dirancang terdiri dari: sensor accelerometer dengan menggunakan modul ADXL345, pembaca nilai sensor dengan menggunakan board Lilypad Arduino, pengirim data dengan menggunakan modul Bluetooth HC-05, dan komputer penerima. Fungsi pengiriman data akselerasi, menampilkan nilai akselerasi, dan perekaman pola akselerasi untuk aktivitas berjalan, duduk, dan berdiri sudah dapat berfungsi dengan baik.
Effects of albinism on Pseudomonas putida infection on convict cichlid (Cichlasoma nigrofasciatum)
Authors: KAYIŞ Şevki , ER Akif , İPEK Zeynep Zehra
Published: May 2019

In the present study, naturally infected albino convict cichlids (Cichlasoma
nigrofasciatum) were examined bacteriologically. The result of the examination
Puseudomonas putida was
isolated from the fish. After this result, comparing the difference of this
infection in normal and albino fish was aimed. So, the trial system for this
purpose was established. Normal and albino fish were infected by the bacteria
and the results were observed. At the end of the experiment, all albino fish
were observed to have died due to infection. Whereas deaths were not observed
in the normal fish. As a result, albino fish (Cichlasoma nigrofasciatum) were found to be more sensitive to Puseudomonas putida infection than
normal fish.
Another law is possible
Authors: Aragón Andrade Orlando
Published: May 2019

This article brings together a series of reflections on the history of the Emancipaciones Collective, with the aim of proposing other ways of understanding the law as well as the possibility of building legal practices from militancy. The Collective was born in a critical academic environment. It has transcended this space, making theory inspire the construction of a professional subjectivity where the legal is understood as something intrinsic to the political, and a legal practice that is based on an ecology of knowledge. I present these reflections from my position as a lawyer and militant anthropologist, member of the Emancipations Collective, and I articulate them with the legal processes that we have carried out with the current Purépecha Municipality of Cherán, Michoacán, as well as with certain readings and discussions that together with these processes have marked the course of the history and action of the Collective.
Hasty Identity
Authors: Peláez Padilla Jorge
Published: May 2019

In the past 10 years Mexico has witnessed a significant increase in levels of social mobilization through the use of the law. This article analyzes a campaign of social movements and organizations to promote and push for the enactment of a new mining law in 2012 as a way to stop the rapid expansion of mining projects in the country. As any process of social mobilization there are multiple dimensions of collective efforts; here I pay special attention to framing process. I argue that the coalition between organizations lacked discussions and agreements on the collective identity of the movement, which led to a weak form of collective action. The case study shows that while the law may be a useful framework regarding public opinion, it poses important challenges to build a solid collective identity that serves as unifying factor for sustained collective action.
State of Exception, Law and Economy: A socio-legal approach to the economy of exception in an era of crisis
Authors: Atiles-Osoria Jose Manuel , Whyte David
Published: May 2019

Departing from a critical understanding of the relationship between state, law and power, we propose a critical overview of the concept of the state of exception developed by Giorgio Agamben. We emphasise the idea that the principle of legal exceptionality is not as merely used in response to the current crisis in capitalism, but is an enduring and core technique of power used by states to reproduce economic and colonial power relations. Thus, this paper offers three core points of departure from dominant understandings of the state of exception. First, we urge a rupture of the crude opposition between positive law and the state of exception. Second, we argue for a rejection of limited Western concept of (liberal, political) rights. Finally, we argue for an attention to the materiality of power relations, rather than a narrow focus on the power projected by formal institutions of state power. Nuestra aproximación al concepto de estado de excepción desarrollado por Giorgio Agamben surge de una comprensión crítica de la relación entre Estado, derecho y poder. Hacemos hincapié en que el principio de excepcionalidad jurídica no es meramente utilizado en respuesta a la actual crisis capitalista, sino que es una técnica de poder central y duradera utilizada por el Estado para reproducir relaciones de poder económicas y coloniales. Esta introducción ofrece tres puntos centrales a partir de la comprensión dominante del estado de excepción: primero, planteamos una ruptura con la oposición cruda entre derecho positivo y estado de excepción; segundo, argüimos en favor del rechazo de la concepción limitada occidental (liberal y política) de los derechos; finalmente, defendemos prestar atención a la materialidad de las relaciones de poder, más que al énfasis limitado en el poder protegido por las instituciones formales del poder estatal.Available from: https://doi.org/10.35295/osls.iisl/0000-0000-0000-0976
Autonomy of the Community and Complementary Currencies in relation to State Law
Authors: Radeljak Florencia
Published: May 2019

The emergence of complementary and community currencies (CCCs) at a global and local scale manifests the normative innovation that characterizes these initiatives. Based on three case studies of CCCs in the Basque Country (the Ekhi, the Eusko and the Txantxi) the present paper explores the normative order of the CCCs and their processes of institutionalization through tactics of legal convergence. The level of autonomy of each CCC is systematized from a socio-legal and a socio-economic approach. The study concludes that through CCCs new institutional fields are opened which strengthen the normative and economic autonomy of the communities.
Research on indoor sex work in Poland
Authors: Ślęzak Izabela
Published: May 2019

In this article, I would like to present selected dilemmas connected with conducting empirical sociological studies of indoor sex work in Poland. The dilemmas result from the social, cultural and legal context in which escort agencies operate. The impact of different dimensions of the context is visible both at the level of actions undertaken by escort agency managers and workers as well as the researcher’s opportunities and possibilities for data collection. My considerations are based on qualitative field research which I carried out between 2007 and 2013, at four premises, so-called escort agencies, operating in the Polish city of Lodz. The article will start with an explanation of what escort agencies are, and with a brief outline of the Polish legal provisions related to prostitution, with special emphasis on the situation of escort agencies. I will then characterize the research project briefly, and present some of the challenges posed during its realization.
‘Benchmarking’ a Supreme Court and Federal Court judge in Australia
Authors: Bartlett Francesca , Douglas Heather
Published: May 2019

In this article, we reflect upon the backgrounds and career trajectories of judicial officers currently presiding over the Federal Court and Supreme Courts, which are some of the highest courts, in Australia. We gathered information through publicly available websites in Australia providing official biographical information, and drew on academic efforts to fill in more details about the judiciary. While patchy, the picture today in the Australian judiciary is of a relatively uniform educational and career background – for both male and female judges. Our analysis shows that judges are predominantly recruited from a long career at the private Bar. However, given continued professional barriers to women succeeding in the Australian legal profession which we describe, we argue that it is time to take seriously the stated goals of modern judicial appointment to widen the pool and consider merit that is not solely defined by a benchmark male career.
Turning Feminist Judgments into Jurisprudence
Authors: Réaume Denise
Published: May 2019

The Women’s Court of Canada project is unique in having chosen to focus its rewriting efforts in a specific area of law – constitutional equality cases. This strategy permits an assessment of the WCC jurisprudence to see if it yields a competing ‘theory’ of equality rights that might be used to systematically critique the real jurisprudence and perhaps produce lines of argument capable of redirecting the real law. This effort reveals the pervasive importance of attention to and representation of context to bringing to life the abstract commitments of an account of substantive equality. While not a new discovery, this demonstration of the work context can do across an array of linked cases is illuminating.
