Abstract. Feature detection and matching are key techniques in computer vision and robotics, and have been successfully implemented in many fields. So far there is no performance comparison of feature detectors and matching methods for planetary mapping and rover localization using rover stereo images. In this research, we present a comprehensive evaluation and comparison of six feature detectors, including Moravec, Förstner, Harris, FAST, SIFT and SURF, aiming for optimal implementation of feature-based matching in planetary surface environment. To facilitate quantitative analysis, a series of evaluation criteria, including distribution evenness of matched points, coverage of detected points, and feature matching accuracy, are developed in the research. In order to perform exhaustive evaluation, stereo images, simulated under different baseline, pitch angle, and interval of adjacent rover locations, are taken as experimental data source. The comparison results show that SIFT offers the best overall performance, especially it is less sensitive to changes of image taken at adjacent locations.
OPTIMIZING THE DISTRIBUTION OF TIE POINTS FOR THE BUNDLE ADJUSTMENT
OF HRSC IMAGE MOSAICS

Published: August 2017

Abstract. For a systematic mapping of the Martian surface, the Mars Express orbiter is equipped with a multi-line scanner: Since the beginning of 2004 the High Resolution Stereo Camera (HRSC) regularly acquires long image strips. By now more than 4,000 strips covering nearly the whole planet are available. Due to the nine channels, each with different viewing direction, and partly with different optical filters, each strip provides 3D and color information and allows the generation of digital terrain models (DTMs) and orthophotos. To map larger regions, neighboring HRSC strips can be combined to build DTM and orthophoto mosaics. The global mapping scheme Mars Chart 30 is used to define the extent of these mosaics. In order to avoid unreasonably large data volumes, each MC-30 tile is divided into two parts, combining about 90 strips each. To ensure a seamless fit of these strips, several radiometric and geometric corrections are applied in the photogrammetric process. A simultaneous bundle adjustment of all strips as a block is carried out to estimate their precise exterior orientation. Because size, position, resolution and image quality of the strips in these blocks are heterogeneous, also the quality and distribution of the tie points vary. In absence of ground control points, heights of a global terrain model are used as reference information, and for this task a regular distribution of these tie points is preferable. Besides, their total number should be limited because of computational reasons. In this paper, we present an algorithm, which optimizes the distribution of tie points under these constraints. A large number of tie points used as input is reduced without affecting the geometric stability of the block by preserving connections between strips. This stability is achieved by using a regular grid in object space and discarding, for each grid cell, points which are redundant for the block adjustment. The set of tie points, filtered by the algorithm, shows a more homogenous distribution and is considerably smaller. Used for the block adjustment, it yields results of equal quality, with significantly shorter computation time. In this work, we present experiments with MC-30 half-tile blocks, which confirm our idea for reaching a stable and faster bundle adjustment. The described method is used for the systematic processing of HRSC data.
ELEMENTAL AND TOPOGRAPHIC MAPPING OF LAVA FLOWSTRUCTURES IN
MARE SERENITATIS ON THE MOON

Published: August 2017

Abstract. The detection of lunar lava flows based on local morphology highly depends on the available images. The thickness of lava flows, however, has been studied by many researchers and lunar lava flows are shown to be as thick as 200 m. Lunar lava flows are supposed to be concentrated on the northwestern lunar nearside. In this study we present elemental abundance maps, a petrological map and a digital terrain model (DTM) of a lava flow structure in northern Mare Serenitatis at (18.0° E, 32.4° N) and two possible volcanic vents at (11.2° E, 24.6° N) and (13.5° E, 37.5° N), respectively. Our abundance maps of the refractory elements Ca, Mg and our petrological map were obtained based on hyperspectral image data of the Moon Mineralogy Mapper (M3) instrument. Our DTM was constructed using GLD100 data in combination with a shape from shading based method to M3 and Lunar Reconnaissance Orbiter (LRO) Narrow Angle Camera (NAC) image data. The obtained NAC-based DEM has a very high effective resolution of about 1–2 m which comes close to the resolution of the utilized NAC images without requiring intricate processing of NAC stereo image pairs. As revealed by our elemental maps and DEM, the examined lava flow structure occurs on a boundary between basalts consisting of low-Ca/high-Mg pyroxene and high-Ca/low-Mg pyroxene, respectively. The total thickness of the lava flow is about 100 m, which is a relatively large value, but according to our DEM the lava flow may also be composed of two or more layers.
RETRIEVAL OF MINERAL ABUNDANCES OF THE DELTA REGION IN EBERSWALDE, MARS

Published: August 2017

Abstract. Eberswalde Crater, a hotspot of Mars exploration, possesses an unambiguous hydrological system. However, little research has been performed on the large-scale mineral abundances retrieval in this region. Hence, we employed hyperspectral unmixing technology to quantitatively retrieve mineral abundances of the delta region in Eberswalde. In this paper, the single-scattering albedos were calculated by the Hapke bidirectional reflectance function from Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) data (FRT000060DD) and CRISM spectral library respectively, and a sparse unmixing algorithm was adopted to quantitatively retrieve mineral abundances. The abundance maps show that there are six kinds of minerals (pyroxene, olivine, plagioclase, siderite, diaspore, and tremolite). By comparing minerals spectra obtained from images with corresponding spectra in spectral library, we found the similar trend in both curves. Besides, the mineral abundance maps derived in this study agree well spatially with CRISM parameter maps. From the perspective of mineralogy, the instability of pyroxene and olivine indicates the area in which they distribute is close to provenance, and the original provenance is ultrabasic rock (e.g. peridotite) and basic rock (e.g. gabbro), respectively. And minerals, existing in the area of alluvial fan, also distribute in the outside of alluvial fan, which might be caused by fluid transportation.
AUTOMATIC DETECTION AND RECOGNITION OF CRATERS BASED ON THE SPECTRAL FEATURES OF LUNAR ROCKS AND MINERALS

Published: August 2017

Abstract. Crater-detection approaches can be divided into four categories: manual recognition, shape-profile fitting algorithms, machine-learning methods and geological information-based analysis using terrain and spectral data. The mainstream method is Shape-profile fitting algorithms. Many scholars throughout the world use the illumination gradient information to fit standard circles by least square method. Although this method has achieved good results, it is difficult to identify the craters with poor "visibility", complex structure and composition. Moreover, the accuracy of recognition is difficult to be improved due to the multiple solutions and noise interference. Aiming at the problem, we propose a method for the automatic extraction of impact craters based on spectral characteristics of the moon rocks and minerals: 1) Under the condition of sunlight, the impact craters are extracted from MI by condition matching and the positions as well as diameters of the craters are obtained. 2) Regolith is spilled while lunar is impacted and one of the elements of lunar regolith is iron. Therefore, incorrectly extracted impact craters can be removed by judging whether the crater contains "non iron" element. 3) Craters which are extracted correctly, are divided into two types: simple type and complex type according to their diameters. 4) Get the information of titanium and match the titanium distribution of the complex craters with normal distribution curve, then calculate the goodness of fit and set the threshold. The complex craters can be divided into two types: normal distribution curve type of titanium and non normal distribution curve type of titanium. We validated our proposed method with MI acquired by SELENE. Experimental results demonstrate that the proposed method has good performance in the test area.
AN INVESTIGATION OF THE HYPOTHESES FOR FORMATION OF THE PLATY-RIDGED-POLYGONIZED TERRAIN IN ELYSIUM PLANITIA, MARS

Published: August 2017

Abstract. The origin of the platy-ridged-polygonized (PRP) terrains on Martian surface has long been debated. The terrain has generally been classified as water, pack ice, or basalt lava related flow. The crater counting results of the PRP terrains suggest they are geologically very young; therefore, they are significant in understanding the recent evolution of Mars. This work evaluated the current hypotheses through detailed analysis of the distribution and microtopographies with the High Resolution Imaging Science Experiment (HiRISE) images for the PRP terrains in Elysium Planitia, Mars. Quantitative measurements and statistics of the typical features of the PRP terrains were also made. In addition, we also found an analog site in Tarim Basin in Xinjiang, China. Our results suggest that mud flow is responsible for the formation of the PRP terrains on the Mars surface, although the hypothesis of low-viscosity basalt lava floods cannot be completely excluded. This finding implies that a regional environment suitable for liquid water may have existed in recent geologic time, which has great importance for future Mars scientific exploration.
A ROBUST METHOD FOR STEREO VISUAL ODOMETRY BASED ON MULTIPLE EUCLIDEAN DISTANCE CONSTRAINT AND RANSAC ALGORITHM
Authors: Zhou Q. , Tong X. , Liu S. , Lu X. , Liu S. , Chen P. , Jin Y. , Xie H.
Published: August 2017

Abstract. Visual Odometry (VO) is a critical component for planetary robot navigation and safety. It estimates the ego-motion using stereo images frame by frame. Feature points extraction and matching is one of the key steps for robotic motion estimation which largely influences the precision and robustness. In this work, we choose the Oriented FAST and Rotated BRIEF (ORB) features by considering both accuracy and speed issues. For more robustness in challenging environment e.g., rough terrain or planetary surface, this paper presents a robust outliers elimination method based on Euclidean Distance Constraint (EDC) and Random Sample Consensus (RANSAC) algorithm. In the matching process, a set of ORB feature points are extracted from the current left and right synchronous images and the Brute Force (BF) matcher is used to find the correspondences between the two images for the Space Intersection. Then the EDC and RANSAC algorithms are carried out to eliminate mismatches whose distances are beyond a predefined threshold. Similarly, when the left image of the next time matches the feature points with the current left images, the EDC and RANSAC are iteratively performed. After the above mentioned, there are exceptional remaining mismatched points in some cases, for which the third time RANSAC is applied to eliminate the effects of those outliers in the estimation of the ego-motion parameters (Interior Orientation and Exterior Orientation). The proposed approach has been tested on a real-world vehicle dataset and the result benefits from its high robustness.
SMALL CRATERS AND THEIR DIAGNOSTIC POTENTIAL
Authors: Bugiolacchi R.
Published: August 2017

Abstract. I analysed and compared the size-frequency distributions of craters in the Apollo 17 landing region, comprising of six mare terrains with varying morphologies and cratering characteristics, along with three other regions allegedly affected by the same secondary event (Tycho secondary surge). I propose that for the smaller crater sizes (in this work 9–30 m), a] an exponential curve of power −0.18D can approximate Nkm−2 crater densities in a regime of equilibrium, while b] a power function D−3 closely describes the factorised representation of craters by size (1 m). The saturation level within the Central Area suggests that c] either the modelled rates of crater erosion on the Moon should be revised, or that the Tycho event occurred much earlier in time than the current estimate. We propose that d] the size-frequency distribution of small secondary craters may bear the signature (in terms of size-frequency distribution of debris/surge) of the source impact and that this observation should be tested further.
MISSION PROFILE AND DESIGN CHALLENGES FOR MARS
LANDING EXPLORATION

Published: August 2017

Abstract. An orbiter and a descent module will be delivered to Mars in the Chinese first Mars exploration mission. The descent module is composed of a landing platform and a rover. The module will be released into the atmosphere by the orbiter and make a controlled landing on Martian surface. After landing, the rover will egress from the platform to start its science mission. The rover payloads mainly include the subsurface radar, terrain camera, multispectral camera, magnetometer, anemometer to achieve the scientific investigation of the terrain, soil characteristics, material composition, magnetic field, atmosphere, etc. The landing process is divided into three phases (entry phase, parachute descent phase and powered descent phase), which are full of risks. There exit lots of indefinite parameters and design constrain to affect the selection of the landing sites and phase switch (mortaring the parachute, separating the heat shield and cutting off the parachute). A number of new technologies (disk-gap-band parachute, guidance and navigation, etc.) need to be developed. Mars and Earth have gravity and atmosphere conditions that are significantly different from one another. Meaningful environmental conditions cannot be recreated terrestrially on earth. A full-scale flight validation on earth is difficult. Therefore the end-to-end simulation and some critical subsystem test must be considered instead. The challenges above and the corresponding design solutions are introduced in this paper, which can provide reference for the Mars exploration mission.
AN ITERATIVE PIXEL-LEVEL IMAGE MATCHING METHOD FOR MARS MAPPING
USING APPROXIMATE ORTHOPHOTOS

Published: August 2017

Abstract. Mars mapping is essential to the scientific research of the red planet. The special terrain characteristics of Martian surface can be used to develop the targeted image matching method. In this paper, in order to generate high resolution Mars DEM, a pixel-level image matching method for Mars orbital pushbroom images is proposed. The main strategies of our method include: (1) image matching on approximate orthophotos; (2) estimating approximate value of conjugate points by using ground point coordinates of orthophotos; (3) hierarchical image matching; (4) generating DEM and approximate orthophotos at each pyramid level; (5) fast transformation from ground points to image points for pushbroom images. The derived DEM at each pyramid level is used as reference data for the generation of approximate orthophotos at the next pyramid level. With iterative processing, the generated DEM becomes more and more accurate and a very small search window is precise enough for the determination of conjugate points. The images acquired by High Resolution Stereo Camera (HRSC) on European Mars Express were used to verify our method’s feasibility. Experiment results demonstrate that accurate DEM data can be derived with an acceptable time cost by pixel-level image matching.
ESTIMATION OF AEOLIAN DUNE MIGRATION OVER MARTIAN SURFACE EMPLOYING HIGH PRECISION PHOTOGRAMMETRIC MEASUREMENTS
Authors: Kim J.
Published: August 2017

Abstract. At the present time, arguments continue regarding the migration speeds of Martian dune fields and their correlation with atmospheric circulation. However, precisely measuring the spatial translation of Martian dunes has been rarely successful due to the technical difficulties to quantitatively observe expected small surface migrations. Therefore, we developed a generic procedure to measure the migration of dune fields employing a high-accuracy photogrammetric processor and sub-pixel image correlator on the 25-cm resolution High Resolution Imaging Science Experiment (HiRISE). The established algorithms have been tested over a few Martian dune fields. Consequently, migrations over well-known crater dune fields appeared to be almost static for the considerable temporal periods and were weakly correlated with wind directions estimated by the Mars Climate Database. Only over some Martian dune fields, such as Kaiser crater, meaningful migration speeds (> 1m/year) considering photogrammetric error residual have been detected. Currently a technically improved processor to compensate error residual using time series observation is under development and expected to produce the long term migration speed over Martian dune fields where constant HiRISE image acquisitions are available.
COMPARATIVE STUDY OF LUNAR ROUGHNESS FROM MULTI - SOURCE DATA
Authors: Lou Y. , Kang Z.
Published: August 2017

Abstract. The lunar terrain can show its collision and volcanic history. The lunar surface roughness can give a deep indication of the effects of lunar surface magma, sedimentation and uplift. This paper aims to get different information from the roughness through different data sources. Besides introducing the classical Root-mean-square height method and Morphological Surface Roughness (MSR) algorithm, this paper takes the area of the Jurassic mountain uplift in the Sinus Iridum and the Plato Crater area as experimental areas. And then make the comparison and contrast of the lunar roughness derived from LRO's DEM and CE-2 DOM. The experimental results show that the roughness obtained by the traditional roughness calculation method reflect the ups and downs of the topography, while the results obtained by morphological surface roughness algorithm show the smoothness of the lunar surface. So, we can first use the surface fluctuation situation derived from RMSH to select the landing area range which ensures the lands are gentle. Then the morphological results determine whether the landing area is suitable for the detector walking and observing. The results obtained at two different scales provide a more complete evaluation system for selecting the landing site of the lunar probe.
Laboratory and numerical experiments on stem waves due to monochromatic waves along a vertical wall
Authors: Yoon Sung Bum , Lee Jong In , Kim Young Taek , Shin Choong Hun
Published: August 2017

Abstract. In this study, both laboratory and numerical experiments are conducted to investigate stem waves propagating along a vertical wall developed by the incidence of monochromatic waves. The results show the following features: For small amplitude waves, the wave heights along the wall show a slowly varying undulation. Normalized wave heights perpendicular to the wall show a standing wave pattern. Thus, overall wave pattern in the case of small amplitude waves show a typical diffraction pattern around a semi-infinite thin breakwater. As the amplitude of incident waves increases, both the undulation intensity and the asymptotic normalized wave height decrease along the wall. For larger amplitude waves with smaller angle of incidence, the measured data show clearly stem waves. Numerical simulation results are in good agreement with the results of laboratory experiments. It is found from a simple geometric relationship of wave pattern that the lengthening of wave length due to the nonlinearity of waves is responsible for the development of stem waves along the wall. The existence and the properties of stem waves for sinusoidal waves found theoretically based on numerical simulations are fully supported by the physical experiments conducted in this study.
Spatial and temporal variability of sea-salts in ice cores and snow pits from Fimbul Ice Shelf, Antarctica

Published: August 2017

Abstract. Major ions were analysed in three firn cores from different ice rises located at Fimbul Ice Shelf (FIS): Kupol Ciolkovskogo (KC), Kupol Moskovskij (KM), and Blåskimen Island (BI), a 100 m long core drilled near the FIS edge (S100), and five snow pits (M1, M2, G3, G4, and G5) sampled on the ice shelf. These sites are distributed over the entire FIS area so that they provide a variety of elevation and distance to the sea. Sea-salt species (mainly Na+ and Cl−) generally dominate the precipitation chemistry in the study region. Concentrations of these ions were found to decrease with latitude and distance from the sea. We associate a significant six-fold increase in sea-salts observed in the S100 core after the 1950s with a change in deposition regime. This increase in sea-salt concentrations is synchronous with a shift in non-sea-salt sulfate (nssSO42−) toward negative values, suggesting a possible contribution of fractionated aerosol to the sea-salt load in the S100 core most likely by dry deposition. In contrast, wet deposition of atmospheric sea-salts is dominant in the three ice rises cores, and no evidence of a significant contribution of fractionated sea-salt to these sites was found. In summary, these results suggest that the S100 core contains a more local sea-salt signal, dominated by processes during sea-ice formation in the neighbouring waters. In contrast, the ice rises cores register the larger-scale signal of atmospheric flow conditions and transport of sea-salt aerosols produced over open water rather than local changes in sea-ice, wind-blown snow accumulated over sea-ice, and frost flower formation. These findings are a contribution to the understanding of the mechanisms behind sea-salt aerosol production, transport and deposition at coastal Antarctic sites, and for the improvement of the current Antarctic sea-ice reconstructions based on sea-salt chemical proxies obtained from ice cores.

Published: August 2017

La investigación comparada sobre instituciones políticas ha comenzado a girar su foco del diseño institucional formal hacia la fortaleza institucional. Más que asumir la coincidencia entre las reglas formales y comportamiento político, estos estudios examinan cómo la variación en la estabilidad y/o imposición de las reglas formales moldean las expectativas y el comportamiento de los actores. Este artículo explora la agenda emergente de investigación sobre fortaleza institucional. Desagrega el concepto de fortaleza institucional en dos dimensiones -imposición y estabilidad- y argumenta que las instituciones varían ampliamente con respecto a ambas. El artículo luego examina las fuentes de esta variación y sus implicancias para la investigación comparada. Muestra cómo la investigación reciente acerca de las instituciones débiles puede ser utilizada para refinar las teorías existentes sobre los efectos, diseño y desarrollo institucionales, la que debería expandir su alcance comparativo. La conclusión examina diferentes posibilidades para desarrollar medidas comparativas de fortaleza institucional.Palabras clave: Instituciones políticas - desarrollo institucional - instituciones débiles - imposición - estabilidad - países en desarrollo.
LIFO Distortion in the Oil Industry – Revisited
Authors: Li June , Sun Megan Y.
Published: August 2017

LIFO (Last in First out) inventory method has been widely used by US publicly traded companies for its tax advantages in many years. However, LIFO is expected to be repealed with the impending acceptance ofIFRS(the International Financial Reporting Standards) by theSEC. The repeal of LIFO will significantly increase the tax liabilities of those companies previously using LIFO. One hardest hit industry by repeal of LIFO is oil industry. Our study investigates the use of LIFO inventory method in oil industry from 2008 through 2015. The primary focus of this study is the accounting information distortion as a result of using LIFO. We document severe accounting information distortion in the areas of working capital and inventory turnover. Though not as severe, we also observe very significant distortions in the areas of gross profit and current ratio. The accounting information gets increasingly distorted from 2008 to 2011. However the trend reverses from 2012 to 2015. Each of the Obama administration’s budgets proposals proposed the elimination of LIFO for inventories. We believe the findings of our research have significant implications for the policy makers. In addition, a full adoption ofIFRS, which prohibits LIFO, is unlikely in the near future. Non-public companies who are not under the jurisdiction of theSECmay still continue to use LIFO after the adoption of IFRS.
To Investigate ESL Students’ Instrumental and Integrative Motivation towards English Language Learning in a Chinese School in Penang: Case Study
Authors: Hong Yee Chee , Ganapathy Malini
Published: August 2017

Malaysians have long realised the importance of being competent in English as one of the success factors in attaining their future goals. However, English is taught as a second language in Malaysia, and it is not easy to teach under such a foreign context, because authentic input may not exist beyond the classroom, especially in Chinese private schools. In this scenario, English is learnt as a subject with 10 sessions per week, which is considered insufficient for students to master the language effectively. Past research highlights the significance of motivation in English language acquisition. Motivated students tend to put in more effort in their academic endeavours by showing more persistence in their learning process. The purpose of the study was to identify and analyse whether instrumental or integrative motivation plays a more important role in promoting Form Four ESL students’ English language learning. Furthermore, examine the areas of problems that affect ESL students’ motivation towards English language learning. This study was a qualitative case study that used focus group interviews to elicit data from 12 students in a secondary school in Penang. The findings of this research indicate that students are more instrumentally motivated than integratively motivated in ESL learning. Instrumental motivation is found to have a greater impact on students’ English language learning. This research also highlights that vocabulary and grammar are the biggest areas of problems that are encountered by students during their ESL learning process, which further influence their speaking and writing skills.

Published: August 2017

Succession is a  complex process.  It touches issues related to transfer of
ownership, management and knowledge in family firms.  It is a  process that
requires adequate preparation stage and needs to be planned in time. It starts much
before successor involvement in business matters, and ends up with incumbent
retirement. In relation to the aforementioned argumentation the aim of the paper is evaluation and synthesis of the most crucial achievements in the field of research
on succession in family firms. The paper is a review of scientific works discussing
the process of conducting succession in family firms, from planning stage to the
successor selection. The paper is based on articles published in well‑known foreign
journals and covers the period of the past 40 years. Conducted research proved
that different scholars involved in family entrepreneurship research show their
unabated interest in succession problems. Transferring the business to the next
generation is still a controversial issue and there is no way to avoid many personal
or business conflicts.

not possible without continuous increasing of the level of education of workers – human
resources. Lifelong education thus inevitably interferes into the life of every individual,
regardless of their age, sex or job position. These are fundamental starting points from
which the article comes out. The objective of the paper is to show that in present days
lifelong education has a non‑substitutable place in the development of human resources.
The partial objective is to analyze the concept of lifelong learning from the concept point
of view both theoretically and on the basis of the secondary analysis of the representative
research according to the results publicized by the Czech Statistical Office and to empha‑
size the importance of formal, non‑formal and informal education in the development

passages between education and employment. The necessity of the conceptual intercon‑
nection of the educational system is the prerequisite for enabling acquiring qualifications
in various ways, and that is in the course of the whole life of an individual. In the first
part the article than deals with theoretical basis of lifelong education, which it comes out
from the analysis of documents of significant European and world institutions, as from
the Memorandum of the EU on lifelong learning, from  documents of the OECD, from
the concept of permanent education of the Council of Europe or from the conceptual
document Learning to be issued by the organization of the UNESCO. Through analysis
of the documents and further literary sources the authors embark on the description of
the contemporary concept of lifelong education which has been applied since the 1990s
century. The fundamental issue of professional education and preparation to usability
in the job life is in this concept. The second part of the article analyses statistical data
related to single forms of lifelong education – formal education, non‑formal education
and informal education from the point of view of the human resources development. The
article presents concrete data on involvement of employees and employers into the process
of lifelong learning, whereas its conclusion summarizes the solved issue and reaches the

Os estados foram classificados quanto à eficiência, sendo possível realizar comparações entre os mesmos e entre as regiões brasileiras. Os resultados indicam que 25,92% dos estados brasileiros apresentaram gastos eficientes enquanto 74,08% apresentaram resultados ineficientes, apontando para a necessidade de melhorias na gestão educacional e dos recursos utilizados. Conclui-se que a educação merece especial atenção por parte do Estado, principalmente por impactar no nível de bem-estar da população, contribuir para maior produtividade e gerar desenvolvimento.

Este estudo investigou o papel desempenhado por atividades de P&D e clientes nas práticas de gestão da inovação em empresas desenvolvedoras de serviços de software no Distrito Federal (DF). Realizou-se estudo de casos múltiplos com dez unidades de análise com coleta de evidências por entrevistas semiestruturadas e análise de conteúdo por codificação temática. Os resultados permitiram caracterizar o processo empírico de gestão da inovação efetivamente adotado nos casos como sendo de baixa formalização, baixa estruturação e com altos índices de retrabalho, sendo muitas vezes disparado por fontes não tradicionais. Ressalta-se como principal contribuição do artigo o apontamento da dissonância entre o discurso dos entrevistados sobre a importância de clientes e P&D e o efetivo papel desempenhado por esses inputs nas práticas organizacionais. Conclui-se, assim, que os modelos teóricos embasam o discurso dos entrevistados; mas não suas práticas organizacionais.
Revision of Chinese mainland Hybovalgus Kolbe, 1904, with description of a new species, and Excisivalgus Endrödi, 1952 reduced to synonymy with Hybovalgus (Coleoptera: Scarabaeidae)
Authors: Ricchiardi Enrico , Li Sha
Published: August 2017

The genus Hybovalgus Kolbe, 1904 is represented by eight species on the Chinese mainland, many of which also inhabit northern Vietnam and Laos. Species of Hybovalgus are endemic to this area, and to the island of Taiwan. Until now, there is a lot of confusion in our knowledge of Hybovalgus on mainland China, due to erroneous descriptions of new species by European entomologists and incorrect identifications of specimens by local entomologists. Study of more material and many types has clarified this situation by better defining the species, synonymizing some of them, describing one new species, Hybovalgus calvus sp. nov. and recognizing the fact that females of two species were included in the new genus Excisivalgus Endrödi, 1952, which is here synonymized with Hybovalgus.

Collective nostalgia refers to longing for the way society used to be. We tested whether collective nostalgia is associated with ingroup-favoring collective action and whether this association is mediated by outgroup-directed anger and outgroup-directed contempt. We conducted an online study of Hong Kong residents (N = 111) during a large-scale democratic social movement, the Umbrella Movement, that took place in Hong Kong in 2014 in response to proposed electoral reforms by the Chinese government in Mainland China. Reported collective nostalgia for Hong Kong’s past was high in our sample and collective nostalgia predicted stronger involvement in ingroup-favoring collective action, and it did so indirectly via higher intensity of outgroup-directed anger (but not through outgroup-directed contempt). We argue that collective nostalgia has implications for strengthening ingroup-serving collective action, and we highlight the importance of arousal of group-based emotions in this process.
The influence of nonsinusoidal supply voltage on the amount of power consumption and electricity meter readings

Published: August 2017

During electricity generation, transformation, distribution and consumption, distortions of voltage and current sinusoidal signals occur. Most consumers are non-linear, and a significant content of higher harmonics emerges when they are connected to the supply grid. The algorithms of modern electricity meters take into account most of higher harmonics, whilst with some fallibilities. However, when supply voltage and current have the same amplitude and a various harmonic composition, the readings of electricity meters can vary greatly. This article describes how the harmonic composition of supply voltage and current affects the readings of electricity metering devices. The analysed ratios do not depend on the amplitude of supply voltage.
Peculiarities of current sensors used in contemporary electric energy metering devices
Authors: Volokhin Vitalii , Diahovchenko Illia
Published: August 2017

An electricity meter is a  tool that determines the  amount of electricity transferred to the  network by a  producer and consumed by electrically powered loads. Metering devices are composed of sensitive sensors that simultaneously measure currents and voltages and a  microprocessor, which calculates required values basing on the  received data. This article gives an overview of the most common current sensors, which are used in contemporary electricity metering devices. Their principles, advantages and disadvantages are reviewed, conclusions about the external influences on the sensors, which can lead to the incorrect operation of a meter and wrong definition of consumed electricity, are made.
Reflexão crítica sobre a Lei 10.179/2014 da “nova” Política Estadual de Recursos Hídricos do Estado do Espírito Santo: uma visão geográfica./Critical reflection on Law 10.179 / 2014 of the "new" State Policy of Water Resources of the State of Espírito Santo: a geographical view
Authors: Vervloet Roberto José Hezer Moreira
Published: August 2017

Em março de 2014 foi publicada a Lei Nº 10.179/2014 que dispõe sobre a Política Estadual de Recursos Hídricos e institui o Sistema Integrado de Gerenciamento de Recursos Hídricos do Estado do Espírito Santo – SIGERH/ES. Essa lei substitui a anterior de Nº 5.818/98 que, embora não totalmente antiecológica como a atual, sustentava vários dispositivos jurídicos e conceituais, tendo a água a partir de uma concepção vista como “recurso natural”, importante para manutenção dos processos naturais essenciais à dinâmica flúvio ecológica territorial e funcionalidade dos ecossistemas nas paisagens tropicais. A lei atual foi toda construída a partir de uma lógica fundamentada na concepção da água como insumo para o processo produtivo industrial e atividades econômicas afins, maximizando o uso irresponsável e suprimindo por completo a noção de “recurso natural”, fundamental a cultura ecológica das comunidades tradicionais, agricultura de base sustentável e qualidade de vida nos espaços urbanos, além de evitar “crises hídricas”. Este artigo se fundamenta em uma análise crítica das prerrogativas dessa lei, a partir da visão do geógrafo, evidenciando os principais problemas para a sociedade e de como ela tende a agravar a apropriação inadequada deste recurso natural nas próximas décadas.ABSTRACTIn March 2014, Law Nº 10.179/2014 was published, which provides for the State Policy on Water Resources and establishes the Integrated System for the Management of Water Resources of the State of Espírito Santo - SIGERH / ES.This law replaces the former of No. 5.818 / 98 which, while not totally anti-ecological like the current one, supported several legal and conceptual devices,taking the water from a conception seen as "natural resource",important for the maintenance of the natural processes essential to the dynamic ecological river flow and ecosystem functionality in the tropical landscapes. The current law was all built from a logic based on the con - ception of water as an input to the industrial production processand related economic activities,maximizing irresponsible use and completely suppressing the notion of "na - tural resource",essential to the ecological culture of traditional communities, sustaina - ble agriculture and quality of life in urban spaces, in addition to avoiding "water crises". This article is based on a critical analysis of the prerogatives of this law, from the view of the geographer, highlighting the main problems for society and how it tends to ag - gravate the inappropriate appropriation of this natural resource in the coming decades.Keywords: water, water resources, water crisis, politics, territory.
Automated Probabilistic System Architecture Analysis in the Multi-Attribute Prediction Language (MAPL): Iteratively Developed using Multiple Case Studies
Authors: Lagerström Robert , Johnson Pontus , Ekstedt Mathias , Franke Ulrik , Shahzad Khurram
Published: August 2017

The Multi-Attribute Prediction Language (MAPL), an analysis metamodel for non-functional qualities of system architectures, is introduced. MAPL features automate analysis in five non-functional areas: service cost, service availability, data accuracy, application coupling, and application size. In addition, MAPL explicitly includes utility modeling to make trade-offs between the qualities. The article introduces how each of the five non-functional qualities are modeled and quantitatively analyzed based on the ArchiMate standard for enterprise architecture modeling and the previously published Predictive, Probabilistic Architecture Modeling Framework, building on the well-known UML and OCL formalisms. The main contribution of MAPL lies in the probabilistic use of multi-attribute utility theory for the trade-off analysis of the non-functional properties. Additionally, MAPL proposes novel model-based analyses of several non-functional attributes. We also report how MAPL has iteratively been developed using multiple case studies.
