Rotational Stabilization of Cargo Container Slung Loads
Authors: Cicolani Luigi , Ivler Christina , Ott Carl , Raz Reuben , Rosen Aviv
Published: August 2015

The stabilization of “difficult” loads that become aerodynamically unstable at airspeeds well below the power-limited speed of the helicopter-load configuration has been studied since the 1960s. This paper looks at the possibility of stabilizing slung loads in forward flight
by imposing a slow steady rotation in yaw (spin stabilization). Slow rotations of 100–150 deg/s suffice to suppress the pendulum motions of the load. A swivel is required at the hook, and only a few foot-pounds of yaw moment are needed to overcome swivel friction and impose the desired
yaw rate. The approach is limited to single-point suspensions. A stabilizer design consisting of a one-shaft anemometer-like device with hemispherical cups at the ends was developed in wind tunnel tests. The shaft angle can be controlled to vary the applied yaw moment and allow feedback regulation
of the load yaw rate. Flight tests with two cargo containers demonstrated that a simple linear control law with fixed gains was effective in maintaining the desired yaw rate in forward flight over the range of configurations of the test loads. Wind tunnel data were obtained at all stages of
the development and testing and proved to be an accurate source of design data and an accurate predictor of performance in flight.
Geology of Mayo Lake, Scougale Creek and McQuesten Lake map-areas
Authors: Green L H
Published: August 2015

The Mayo Lake, Scougale Creek and McQuesten Lake map-areas cover about 790 square miles in central Yukon Territory bounded by latitudes 63°45 ' and 64°15'N and longitudes 134°30' and 135°30'W. The area lies within Stewart Plateau, a
subdivision of the Yukon Plateau. Much of the area is underlain by quartzite, phyllitic quartzite, and phyllite that have been separated into a number of map-units believed to range from Precambrian to Mesozoic in age. The Keno Hill Quartzite, a distinctive, dark, massive quartzite, is the marker
horizon for mapping. This quartzite, formerly considered of Precambrian age, is now believed to be of Early Cretaceous age on the basis of work to the west of the present area. The Keno Hill Quartzite and the underlying Lower Schist have been intruded by numerous sills of diorite and gabbro, now
extensively altered to secondary minerals. These sills, locally referred to as greenstone, are believed to have been intruded prior to and possibly also in the early stages of an older deformation. Fold-like terminations of a number of greenstone bodies are described. Granitic rocks of probable Late
Cretaceous age intrude older sedimentary rocks. Two periods of folding and faulting are believed to have affected rocks of the area, ( 1) an older deformation that may have begun by the thrusting of Precambrian rocks on Mesozoic rocks followed by extensive northward movement with the production of
complex folds, both small- and large-scale, and pervasive development of foliation ; and (2) a younger deformation marked by open folding, the formation of wrinkle lineation and possible rotation of earlier formed fold axes. Late faulting may be the final phase of this deformation. The area lies
adjacent to and is underlain by the same rocks as the highly productive Keno and Galena Hills silver camp. A number of silver-lead showings have been explored within the area, but those discovered to date lack the high silver values of the main camp.
Metamorphic map of the Canadian Cordillera
Authors: Monger J W H , Hutchison W W
Published: August 2015

The metamorphic map of the Canadian Cordillera is subdivided into nine units based largely on the metamorphic minerals listed in the accompanying inventory. These units arc (I) unmetamorphosed rocks, (l a) low-grade metamorphic rocks with no known index minerals,
(2) rocks of prehnite-pumpellyite metagreywacke facies, (2a , b) rocks transitional between (2) and respectively the (3) blue schist facies and (4) green schist facies , ( 5) rocks of amphibolite facies and (6) granitic rocks. Green schist and amphibolite facies rocks of largely Barrovian type,
accompanied by granitic rocks, arc confined mainly lo two belts, the eastern, Cassiar-Omineca-Columbia belt and the western Coast Mountains belt, that merge in the Yukon and possibly near the International Boundary in the south. Between the belts and flanking them on east and west are
unmetamorphosed and low-grade rocks. This pattern results almost entirely from Mesozoic metamorphism, although there is evidence that the metamorphic history of the Cordillera extends back well into the Precambrian.

Geology of Berens River-Deer Lake map-area, Manitoba and Ontario and a preliminary analysis of tectonic variations in the area
Authors: Ermanovics I F
Published: August 2015

The Berens River -Deer Lake map-area is underlain by massive and layered quartz monzonite and granodiorite which a lso constitute the dominant rock types in the northern part of the adjacent Hecla-Carroll Lake map-area to the south. Gneissose and laye red quartz
monzonite and granodiorite underlie 46 per cent of the area, massive granodiorite 32 per cent and leucoquartz monzonite 19 per cent; metadacite and metasedimentary gneiss constitute 3 per cent. Tectonic variation in both map-areas is synthesized to three domains: metavolcanic-sedimentary rocks
(domain I); an adjacent, hybrid mobile zone containing highgrade gn e iss es and basic plutonic rocks (domain II), and a sialic nucleus comprising massive and layered siliceous plutonic rocks (domain III). Domains I and II constitute a down-faulted remnant of the total volcanic-sedimentary
tectogene, originally deposited on the sialic nucleus of domain III.
Geology of Ordovician to Pennsylvanian rocks, M'clintock Inlet, north coast of Ellesmere Island, Canadian Arctic Archipelago
Authors: Trettin H P
Published: August 2015

The geology of a key a rea of about 380 square miles within the magmatic belt of the Franklinian Geosyncline is described and analyzed. Three major stratigraphic sequences separated by angular unconformities are exposed: (1) A Middle Ordovician or older.
unfossiliferous, partly metamorphosed sequence, more than J,000 feet thick, consists of keratophyres, cherts, slates, and limes tones. (2) A late Middle Ordovician (Wildernessian) to Late Silurian (Ludlovian) sequence, more than 14,600 feet thick, consists of carbonates, keratophyres, and elastic
sediments assigned to seven format ions. These strata were deposited in non-marine to deep-sea environments, predominantly under shallow-water marine and shelf conditions. The elastic sediments, generally coarse grained and immature, were derived from volcanic, sedimentary, and metamorphic terranes
of sialic composition in the present Arctic Ocean region that were periodically above sea level. Volcanism was limited to the Wildernessian-early Richmondian interval, and was probably an after-effect of Middle Ordovician tectonism. (3) A Middle Pennsylvanian and (?) younger sequence, more than
4,400 feet thick, consists of elastic sediments, limestones, and evaporites, deposited in non-marine to shallow-water marine environments. The elastic sediments were partly or wholly derived from nearby northerly sources. Igneous intrusions differ widely in size, composition, and age. Altered dykes
and sills of intermediate to ultrabasic composition are Middle Ordovician and /or older; a major, serpentinized, ultrabasic pluton is Early Devonian or older; small quartz dioritic intrusions are probably Early Devonian (390±21 m.y.). Southerly trending structures, continuous with the extreme
southeastern flank of the Lomonosov Ridge, characterize the northwestern part of the area. Easterly trends, conforming with the predominant structural grain of northern Ellesmere Island, are typical of the south ha lf. Terrains continuous with the Lomonosov Ridge were elevated relative to terrains
to the east in early and middle Paleozoic times. The intersection of the easterly and the southerly trending structures, marked by a structural trough and by ultrabasic intrusions, was repeatedly a site of crustal extension.

Beginning at about 15:30 on June 20, 1993, a sensitive clay flow occurred near the former townsite of Lemieux, Ontario. The failure involved 2.5 to 3.5 Mm3 of sand, silt, and clay which flowed into South Nation Valley, inundating 3.3 km of the valley bottom and
impounding South Nation River. By late June 22, 1993, the river overtopped the dam and again flowed downstream. This paper provides a photographic record of the event and post-failure conditions.
A review of non-strabismic accommodative-vergence anomalies in school-age children. Part 1: Vergence anomalies
Authors: Wajuihian Samuel O. , Hansraj Rekha
Published: August 2015

Comfortable reading and the performance of near point activities involve efficient accommodative and vergence systems. However, accommodative and vergence anomalies are associated with various symptoms that impair efficient near point tasks. Although several studies investigated accommodative-vergence anomalies in school-age populations, their findings were diverse owing to differences in diagnostic techniques and the criteria used to define the variables. The aim of this paper is to derive prevalence and distribution estimates of vergence anomalies in school-age children and address variations in the study methods and findings. Despite variations in the study methods and findings, accommodativevergence anomalies were common in school-age populations. Variations and limitations of previous studies are discussed and recommendations for improving future studies are suggested.

Comfortable reading and the performance of related near point activities involve efficient accommodative and vergence systems. However, accommodative and convergence anomalies are associated with various symptoms of asthenopia that impair efficient near point tasks. In Part 1 of this two-part article, studies on vergence anomalies were reviewed. In the current paper (Part 2), anomalies of accommodation are reviewed. The aims of the latter paper were to derive the prevalence and distribution estimates of anomalies of accommodation in school-age children and address variations in the study methods and findings. Despite variations in the study methods and findings, anomalies of accommodation are prevalent among school-age populations. Variations and limitations of previous studies are discussed and recommendations for improving future studies are suggested.
Limited effect of anthropogenic nitrogen oxides on Secondary Organic Aerosol formation
Authors: Zheng Y. , Unger N. , Hodzic A. , Emmons L. , Knote C. , Tilmes S. , Lamarque J.-F. , Yu P.
Published: August 2015

Abstract. Globally, secondary organic aerosol (SOA) is mostly formed from emissions of biogenic volatile organic compounds (VOCs) by vegetation, but can be modified by human activities as demonstrated in recent research. Specifically, nitrogen oxides (NOx = NO + NO2) have been shown to play a critical role in the chemical formation of low volatility compounds. We have updated the SOA scheme in the global NCAR Community Atmospheric Model version 4 with chemistry (CAM4-chem) by implementing a 4-product Volatility Basis Set (VBS) scheme, including NOx-dependent SOA yields and aging parameterizations. The predicted organic aerosol amounts capture both the magnitude and distribution of US surface annual mean measurements from the Interagency Monitoring of Protected Visual Environments (IMPROVE) network by 50 %, and the simulated vertical profiles are within a factor of two compared to Aerosol Mass Spectrometer (AMS) measurements from 13 aircraft-based field campaigns across different region and seasons. We then perform sensitivity experiments to examine how the SOA loading responds to a 50 % reduction in anthropogenic nitric oxide (NO) emissions in different regions. We find limited SOA reductions of 0.9 to 5.6, 6.4 to 12.0 and 0.9 to 2.8 % for global, the southeast US and the Amazon NOx perturbations, respectively. The fact that SOA formation is almost unaffected by changes in NOx can be largely attributed to buffering in chemical pathways (low- and high-NOx pathways, O3 versus NO3-initiated oxidation) and to offsetting tendencies in the biogenic versus anthropogenic SOA responses.

Abstract. The Pliocene Model Intercomparison Project (PlioMIP) is a co-ordinated international climate modelling initiative to study and understand climate and environments of the Late Pliocene, and their potential relevance in the context of future climate change. PlioMIP operates under the umbrella of the Palaeoclimate Modelling Intercomparison Project (PMIP), which examines multiple intervals in Earth history, the consistency of model predictions in simulating these intervals and their ability to reproduce climate signals preserved in geological climate archives. This paper provides a thorough model intercomparison project description, and documents the experimental design in a detailed way. Specifically, this paper describes the experimental design and boundary conditions that will be utilised for the experiments in Phase 2 of PlioMIP.
EwE-F 1.0: an implementation of Ecopath with Ecosim in Fortran 95/2003 for coupling and integration with other models

Published: August 2015

Abstract. Societal and scientific challenges foster the implementation of the ecosystem approach to marine ecosystem analysis and management, which is a comprehensive means of integrating the direct and indirect effects of multiple stressors on the different components of ecosystems, from physical to chemical and biological and from viruses to fishes and marine mammals. Ecopath with Ecosim (EwE) is a widely used software package, which offers capability for a dynamic description of the multiple interactions occurring within a food web, and, potentially, a crucial component of an integrated platform supporting the ecosystem approach. However, being written for the Microsoft .NET framework, seamless integration of this code with Fortran-based physical and/or biogeochemical oceanographic models is technically not straightforward. In this work we release a re-coding of EwE in Fortran (EwE-F). We believe that the availability of a Fortran version of EwE is an important step towards setting up coupled/integrated modelling schemes utilising this widely adopted software because it (i) increases portability of the EwE models and (ii) provides additional flexibility towards integrating EwE with Fortran-based modelling schemes. Furthermore, EwE-F might help modellers using the Fortran programming language to get close to the EwE approach. In the present work, first fundamentals of EwE-F are introduced, followed by validation of EwE-F against standard EwE utilising sample models. Afterwards, an end-to-end (E2E) ecological representation of the Gulf of Trieste (northern Adriatic Sea) ecosystem is presented as an example of online two-way coupling between an EwE-F food web model and a biogeochemical model. Finally, the possibilities that having EwE-F opens up are discussed.

Abstract. Data assimilation has become a popular method to integrate observations from multiple sources with land surface models to improve predictions of the water and energy cycles of the soil-vegetation-atmosphere continuum. Multivariate data assimilation refers to the simultaneous assimilation of observation data from multiple model state variables into a simulation model. In recent years, several land data assimilation systems have been developed in different research agencies. Because of the software availability or adaptability, these systems are not easy to apply for the purpose of multivariate land data assimilation research. We developed an open source multivariate land data assimilation framework (DasPy) which is implemented using the Python script language mixed with the C++ and Fortran programming languages. LETKF (Local Ensemble Transform Kalman Filter) is implemented as the main data assimilation algorithm, and uncertainties in the data assimilation can be introduced by perturbed atmospheric forcing data, and represented by perturbed soil and vegetation parameters and model initial conditions. The Community Land Model (CLM) was integrated as the model operator. The implementation allows also parameter estimation (soil properties and/or leaf area index) on the basis of the joint state and parameter estimation approach. The Community Microwave Emission Modelling platform (CMEM), COsmic-ray Soil Moisture Interaction Code (COSMIC) and the Two-Source Formulation (TSF) were integrated as observation operators for the assimilation of L-band passive microwave, cosmic-ray soil moisture probe and land surface temperature measurements, respectively. DasPy has been evaluated in several assimilation studies of neutron count intensity (soil moisture), L-band brightness temperature and land surface temperature. DasPy is parallelized using the hybrid Message Passing Interface and Open Multi-Processing techniques. All the input and output data flows are organized efficiently using the commonly used NetCDF file format. Online 1-D and 2-D visualization of data assimilation results is also implemented to facilitate the post simulation analysis. In summary, DasPy is a ready to use open source parallel multivariate land data assimilation framework.
EVALUATION OF STEREO ALGORITHMS FOR OBSTACLE DETECTION WITH FISHEYE LENSES
Authors: Krombach N. , Droeschel D. , Behnke S.
Published: August 2015

Abstract. For autonomous navigation of micro aerial vehicles (MAVs), a robust detection of obstacles with onboard sensors is necessary in order to avoid collisions. Cameras have the potential to perceive the surroundings of MAVs for the reconstruction of their 3D structure. We equipped our MAV with two fisheye stereo camera pairs to achieve an omnidirectional field-of-view. Most stereo algorithms are designed for the standard pinhole camera model, though. Hence, the distortion effects of the fisheye lenses must be properly modeled and model parameters must be identified by suitable calibration procedures. In this work, we evaluate the use of real-time stereo algorithms for depth reconstruction from fisheye cameras together with different methods for calibration. In our experiments, we focus on obstacles occurring in urban environments that are hard to detect due to their low diameter or homogeneous texture.
A ROBUST MATCHING METHOD FOR UNMMANED AERIAL VEHICLE IMAGES WITH DIFFERENT VIEWPOINT ANGLES BASED ON REGIONAL COHERENCY
Authors: Shao Z. , Li C. , Yang N.
Published: August 2015

Abstract. One of the main challenges confronting high-resolution remote sensing image matching is how to address the issue of geometric deformation between images, especially when the images are obtained from different viewpoints. In this paper, a robust matching method for Unmanned Aerial Vehicle images of different viewpoint angles based on regional coherency is proposed. The literature on the geometric transform analysis reveals that if transformations between different pixel pairs are different, they can't be expressed by a uniform affine transform. While for the same real scene, if the instantaneous field of view or the target depth changes is small, transformation between pixels in the whole image can be approximated by an affine transform. On the basis of this analysis, a region coherency matching method for Unmanned Aerial Vehicle images is proposed. In the proposed method, the simplified mapping from image view change to scale change and rotation change has been derived. Through this processing, the matching between view change images can be converted into the matching between rotation and scale changed images. In the method, firstly local image regions are detected and view changes between these local regions are mapped to rotation and scale change by performing local region simulation. And then, point feature detection and matching are implemented in the simulated image regions. Finally, a group of Unmanned Aerial Vehicle images are adopted to verify the performance of proposed matching method respectively, and a comparative analysis with other methods demonstrates the effectiveness of the proposed method.
PRELIMINARY RESULTS FROM THE PORTABLE IMAGERY QUALITY ASSESSMENT TEST FIELD (PIQuAT) OF UAV IMAGERY FOR IMAGERY RECONNAISSANCE PURPOSES

Published: August 2015

Abstract. The article presents a set of initial results of a quality assessment study of 2 different types of sensors mounted on an unmanned aerial vehicle, carried out over an especially designed and constructed test field. The PIQuAT (Portable Imagery Quality Assessment Test Field) field had been designed especially for the purposes of determining the quality parameters of UAV sensors, especially in terms of the spatial, spectral and radiometric resolutions and chosen geometric aspects. The sensor used include a multispectral framing camera and a high-resolution RGB sensor. The flights were conducted from a number of altitudes ranging from 10 m to 200 m above the test field. Acquiring data at a number of different altitudes allowed the authors to evaluate the obtained results and check for possible linearity of the calculated quality assessment parameters. The radiometric properties of the sensors were evaluated from images of the grayscale target section of the PIQuAT field. The spectral resolution of the imagery was determined based on a number of test samples with known spectral reflectance curves. These reference spectral reflectance curves were then compared with spectral reflectance coefficients at the wavelengths registered by the miniMCA camera. Before conducting all of these experiments in field conditions, the interior orientation parameters were calculated for the MiniMCA and RGB sensor in laboratory conditions. These parameters include: the actual pixel size on the detector, distortion parameters, calibrated focal length (CFL) and the coordinates of the principal point of autocollimation (miniMCA - for each of the six channels separately.

The concept was defined in late 2009 and it is designed for a maximum weight of 25 kg which is now the accepted cut-off defining small civil UASs. A very clean tractor propeller layout is used with a lightweight composite structure and a high aspect ratio wing to obtain good range and endurance. The design features and performance of the initial electrically powered version are discussed and progress with developing a multifuel engine version is described. The system includes features enabling operation beyond line of sight (BLOS) and the proving missions are described. The vehicle has been used for aerial photography and low cost mapping using a professional grade Nikon DSLR camera. For forest fire research a FLIR A65 IR camera was used, while for georeferenced mapping a new Applanix AP20 system was calibrated with the Nikon camera. The sorties to be described include forest fire research, wildlife photography of bowhead whales in the Arctic and surveys of endangered caribou in a remote area of Labrador, with all these applications including the DSLR camera.

Published: August 2015

Abstract. In the discovering, identifying and mapping work of heritage objects in forest or desert areas, LiDAR ensures work efficiency and can provide the most complete and accurate 3D data. In the field of heritage documentation in China, the integration of LiDAR and small UAV is highly desirable. However, due to issues on the vibration of flying platform, load capacity, safety and other factors, not all UAVs can be used as LiDAR carriers. Therefore, the selection and design of suitable UAVs are very important. Little research has been done in this area and related experiments, complete test data and clear conclusions are hard to find. After long-term selection, design, trial-manufacturing and testing, the authors compare the vibration, capacity, reliability, stability of many UAV types, and finally develop two UAV platforms which are most suitable for carrying LiDAR for heritage mapping projects.
UAV POSITIONING AND COLLISION AVOIDANCE BASED ON RSS MEASUREMENTS
Authors: Masiero A. , Fissore F. , Guarnieri A. , Pirotti F. , Vettore A.
Published: August 2015

Abstract. In recent years, Unmanned Aerial Vehicles (UAVs) are attracting more and more attention in both the research and industrial communities: indeed, the possibility to use them in a wide range of remote sensing applications makes them a very flexible and attractive solution in both civil and commercial cases (e.g. precision agriculture, security and control, monitoring of sites, exploration of areas difficult to reach). Most of the existing UAV positioning systems rely on the use of the GPS signal. Despite this can be a satisfactory solution in open environments where the GPS signal is available, there are several operating conditions of interest where it is unavailable or unreliable (e.g. close to high buildings, or mountains, in indoor environments). Consequently, a different approach has to be adopted in these cases. This paper considers the use ofWiFi measurements in order to obtain position estimations of the device of interest. More specifically, to limit the costs for the devices involved in the positioning operations, an approach based on radio signal strengths (RSS) measurements is considered. Thanks to the use of a Kalman filter, the proposed approach takes advantage of the temporal dynamic of the device of interest in order to improve the positioning results initially provided by means of maximum likelihood estimations. The considered UAVs are assumed to be provided with communication devices, which can allow them to communicate with each other in order to improve their cooperation abilities. In particular, the collision avoidance problem is examined in this work.
WILDLIFE MULTISPECIES REMOTE SENSING USING VISIBLE AND THERMAL INFRARED IMAGERY ACQUIRED FROM AN UNMANNED AERIAL VEHICLE (UAV)
Authors: Chrétien L.-P. , Théau J. , Ménard P.
Published: August 2015

Abstract. Wildlife aerial surveys require time and significant resources. Multispecies detection could reduce costs to a single census for species that coexist spatially. Traditional methods are demanding for observers in terms of concentration and are not adapted to multispecies censuses. The processing of multispectral aerial imagery acquired from an unmanned aerial vehicle (UAV) represents a potential solution for multispecies detection. The method used in this study is based on a multicriteria object-based image analysis applied on visible and thermal infrared imagery acquired from a UAV. This project aimed to detect American bison, fallow deer, gray wolves, and elks located in separate enclosures with a known number of individuals. Results showed that all bison and elks were detected without errors, while for deer and wolves, 0–2 individuals per flight line were mistaken with ground elements or undetected. This approach also detected simultaneously and separately the four targeted species even in the presence of other untargeted ones. These results confirm the potential of multispectral imagery acquired from UAV for wildlife census. Its operational application remains limited to small areas related to the current regulations and available technology. Standardization of the workflow will help to reduce time and expertise requirements for such technology.
PLANAR CONSTRAINTS FOR AN IMPROVED UAV-IMAGE-BASED DENSE POINT CLOUD GENERATION
Authors: He F. , Habib A. , Al-Rawabdeh A.
Published: August 2015

Abstract. In this paper, we proposed a new refinement procedure for the semi-global dense image matching. In order to remove outliers and improve the disparity image derived from the semi-global algorithm, both the local smoothness constraint and point cloud segments are utilized. Compared with current refinement technique, which usually assumes the correspondences between planar surfaces and 2D image segments, our proposed approach can effectively deal with object with both planar and curved surfaces. Meanwhile, since 3D point clouds contain more precise geometric information regarding to the reconstructed objects, the planar surfaces identified in our approach can be more accurate. In order to illustrate the feasibility of our approach, several experimental tests are conducted on both Middlebury test and real UAV-image datasets. The results demonstrate that our approach has a good performance on improving the quality of the derived dense image-based point cloud.
SINGLE IMAGE DEHAZING FOR VISIBILITY IMPROVEMENT
Authors: Zhai Y. , Ji D.
Published: August 2015

Abstract. Images captured in foggy weather conditions often suffer from poor visibility, which will create a lot of impacts on the outdoor computer vision systems, such as video surveillance, intelligent transportation assistance system, remote sensing space cameras and so on. In this paper, we propose a new transmission estimated method to improve the visibility of single input image (with fog or haze), as well as the image’s details. Our approach stems from two important statistical observations about haze-free images and the haze itself. First, the famous dark channel prior, a statistics of the haze-free outdoor images, can be used to estimate the thickness of the haze; and second, gradient prior law of transmission maps, which is based on dark channel prior. By integrating these two priors, to estimate the unknown scene transmission map is modeled into a TV-regularization optimization problem. The experimental results show that the proposed approach can effectively improve the visibility and keep the details of fog degraded images in the meanwhile.
WORKFLOW FOR BUILDING A HYPERSPECTRAL UAV: CHALLENGES AND OPPORTUNITIES
Authors: Proctor C. , He Y.
Published: August 2015

Abstract. Owing to the limited payload capacities of most UAV platforms within an academic research budget, many UAV systems utilize commercial RGB cameras or modified sensors with some capacity for sensing in the NIR. However, many applications require higher spectral fidelity that only hyperspectral sensors can offer. For instance, the Photochemical Reflectance Index relies upon the narrow band absorbance of xanthophyll pigments at 531 and 570nm to quantify photosynthetic light use efficiency which are important indicators of productivity and stress in agricultural and forest ecosystems. Thus, our research group has been working on building a research paradigm around a commercial off-the-shelf hyperspectral sensor and UAV. This paper discusses some of the key decisions made regarding selection of equipment and navigating the regulatory and logistical landmines. The imagery collected to date and the options available to process and utilize hyperspectral data are discussed at the end.
UNMANNED AERIAL VEHICLES FOR ALIEN PLANT SPECIES DETECTION AND MONITORING

Published: August 2015

Abstract. Invasive species spread rapidly and their eradication is difficult. New methods enabling fast and efficient monitoring are urgently needed for their successful control. Remote sensing can improve early detection of invading plants and make their management more efficient and less expensive. In an ongoing project in the Czech Republic, we aim at developing innovative methods of mapping invasive plant species (semi-automatic detection algorithms) by using purposely designed unmanned aircraft (UAV). We examine possibilities for detection of two tree and two herb invasive species. Our aim is to establish fast, repeatable and efficient computer-assisted method of timely monitoring, reducing the costs of extensive field campaigns. For finding the best detection algorithm we test various classification approaches (object-, pixel-based and hybrid). Thanks to its flexibility and low cost, UAV enables assessing the effect of phenological stage and spatial resolution, and is most suitable for monitoring the efficiency of eradication efforts. However, several challenges exist in UAV application, such as geometrical and radiometric distortions, high amount of data to be processed and legal constrains for the UAV flight missions over urban areas (often highly invaded). The newly proposed UAV approach shall serve invasive species researchers, management practitioners and policy makers.
Socioeconomic modifications of the universal soil loss equation
Authors: Erol A. , Koşkan Ö. , Başaran M. A.
Published: August 2015

Abstract. While social scientists have long focused on socioeconomic and demographic factors, physical modelers typically study soil loss using physical factors. In the current environment, it is becoming increasingly important to consider both approaches simultaneously for the conservation of soil and water, and the improvement of land use conditions. This study uses physical and socioeconomic factors to find a coefficient that evaluates the combination of these factors. It aims to determine the effect of socioeconomic factors on soil loss and, in turn, to modify the universal soil loss equation (USLE). The methodology employed in this study specifies that soil loss can be calculated and predicted by comparing the degree of soil loss in watersheds, with and without human influence, given the same overall conditions. A coefficient for socioeconomic factors, therefore, has been determined based on adjoining watersheds (WS I and II), employing simulation methods. Combinations of C and P factors were used in the USLE to find the impact of their contributions to soil loss. The results revealed that these combinations provided good estimation of soil loss amounts for the second watershed, i.e., WS II, from the adjoining watersheds studied in this work. This study shows that a coefficient of 0.008 modified the USLE to reflect the socioeconomic factors, such as settlement, influencing the amount of soil loss in the studied watersheds.

Authors: Drwenski Matt
Published: August 2015

This paper attempts a number of tasks that will further the study of world-historical human inequality, by arguing for a comprehensive understanding of inequality and by informally comparing and aggregating multiple datasets. The paper briefly surveys and critiques the existing corpus of inequality data, noting areas of overlap, opportunities for harmonization of data, and the coverage of the historical information.  The inclusion of micro-level data from historical scholarship that is not in communication with the social scientific studies is essential to further the field. The paper concludes with a regional and global narrative of human inequality over the last two centuries.

Mental Toughness and Emotional Maturity in Basketball Performance: Identifying Performance Indicators
Authors: Singh Davinder
Published: August 2015

The present study was aimed to indentify the mental toughness and emotional maturity among basketball players. For this purpose, sixty female basketball players of 20 to 25 years of age were selected. They were further divided into three groups; (i.e., N1=20; District, N2=20; State and N3=20 National). To determine level of Mental Toughness among subjects, Mental Toughness, constructed by Goldberg et al. (1998) was administered. To determine level of Emotional Maturity among subjects, Emotional Maturity Scale constructed by Singh and Bhargava’s (1988) was administered. One way Analysis of Variance (ANOVA) was employed to find out the intra-group differences. The findings show that no significant differences were found among female basketball players on the sub-variables of Mental Toughness. Conculdingly from the above findings that insignificant differences were present among female basketball players on the sub-variables of Emotional Maturity.
The Influence of Knowledge Sharing on Employee Innovation Capabilities
Authors: Ologbo Andrew C. , Md Nor Khalil , Okyere-Kwakye Eugene
Published: August 2015

Knowledge is the most vital element in innovation. According to the literature, knowledge management plays a prominent role which enables firms to leverage their innovation capabilities into product and service development. Knowledge sharing which is the important process of knowledge management is therefore crucial to enhance an employee innovation capability which is itself a component of the overall firm innovation capabilities.Purpose: The purpose of this paper is to empirically examine the influence of knowledge sharing on employee innovation capabilities. Design/methodology/approach: A questionnaire-based survey was employed for the data collection. A total of 204 engineers working with manufacturing firms in Malaysia participated in the survey. Findings: The findings show that knowledge sharing influences employee innovation capabilities.
Humanely Killed?
Authors: Johnson Jeff
Published: August 2015

Humanely Killed? Jeff Johnson St. Catherine University, Saint Paul, Minnesota. Standard philosophical approaches to the issue of eating animals who are thought to have been humanely killed typically turn on decisions around the issue of moral status or on weighing benefits and harms of killing. Rather than pursuing these lines of inquiry, I bring out circumstances that have gotten lost in thinking we can take moral cover under the idea that farmed animals are killed humanely. In thinking about whether farmed animals have been killed humanely, we are asked to focus on the whether the deaths of these animals are painful. But much more is involved when we attend to other cases in which animals are thought to have been killed humanely. In view of these discrepancies, I argue that it is much more difficult than we might suppose to take moral cover under the idea that farmed animals can be killed humanely.
Are Nonhuman Animals Persons? A Process Theistic Response
Authors: Dombrowski Daniel A.
Published: August 2015

In this article I defend the claim that nonhuman animals can be persons. In this regard I rely on the thought of neoclassical or process theists like Alfred North Whitehead and Charles Hartshorne. Their moderate stance regarding personhood is in contrast to the influential classical theistic view, which denies personhood status to nonhuman animals.
Lucretius’s Venus and Epicurean Compassion toward Nondomesticated Animals
Authors: Lazo Robert Patrick Stone
Published: August 2015

Lucretius believed that the gods were wholly perfect and self-sufficient, not vengeful and requiring appeasement. He believed contemplation of the gods allowed one to reach a similar state, as it clarified what was important for a successful human life. This article intends to examine how this theology affects Lucretius’s view of nonhuman-human interaction. It will reach the conclusion that Lucretian Epicureanism contains within it a deep appreciation of the value of life and so prohibits unnecessary disturbance to the lives of others, including nonhuman animals.
Peter Singer, Emmanuel Levinas, Christian Agape, and the Spiritual Heart of Animal Liberation
Authors: Greenway William
Published: August 2015

This article affirms Peter Singer’s calls for universal benevolence and for animal liberation. Singer, however, is unable to provide grounds for his ethics and is unable to answer the question, “why act morally?” I suggest Jewish philosopher Emmanuel Levinas unfolds an essentially Christian notion of agape that unveils a reasonable moral ground for ethics that answers the question, “why act morally?” A Levinasian ethic also forecloses some of Singer’s more notorious conclusions and better articulates and legitimates the moral dynamics and ethical contentions that made Singer’s “Famine, Affluence, and Morality” and Animal Liberation so influential.
Ameliorating Nonhuman Animals’ Lives: Erin McKenna’s Pets, People, and Pragmatism
Authors: Palop Lidia de Tienda
Published: August 2015

This review article discusses Erin McKenna’s pragmatist theory concerning the ethical treatment of companion animals, which she lays out in Pets, People and Pragmatism. McKenna develops a middle-ground view between the two opposite positions that frame the current debate on companion animals, focussing on the relationship between human and nonhuman animal beings. I suggest that the question of whether the domestication of nonhuman animals is not only a natural process, but also a desirable one, still remains unclear.
First successful capture and satellite tracking of a West Indian manatee (Trichechus manatus) in Panama: feasibility of capture and telemetry techniques

It is currently unknown how important the Central American countries south of Belize are as a link between manatee populations in the north (Belize and Mexico) and populations in South America. Therefore, apart from knowing where manatees are found, it is important to understand how manatees are using these habitats and if they are moving between countries or distinct population centers. Here we report the results of a multi-national and multiinstitutional collaboration resulting in the first successful capture and satellite tracking of a West Indian manatee in southern Central America

Distinct transcriptional responses elicited by unfolded nuclear or cytoplasmic protein in mammalian cells
Authors: Miyazaki Yusuke , Chen Ling-chun , Chu Bernard W , Swigut Tomek , Wandless Thomas J
Published: August 2015

Eukaryotic cells possess a variety of signaling pathways that prevent accumulation of unfolded and misfolded proteins. Chief among these is the heat shock response (HSR), which is assumed to respond to unfolded proteins in the cytosol and nucleus alike. In this study, we probe this axiom further using engineered proteins called ‘destabilizing domains’, whose folding state we control with a small molecule. The sudden appearance of unfolded protein in mammalian cells elicits a robust transcriptional response, which is distinct from the HSR and other known pathways that respond to unfolded proteins. The cellular response to unfolded protein is strikingly different in the nucleus and the cytosol, although unfolded protein in either compartment engages the p53 network. This response provides cross-protection during subsequent proteotoxic stress, suggesting that it is a central component of protein quality control networks, and like the HSR, is likely to influence the initiation and progression of human pathologies.
