Quality of terrestrial data derived from UAV photogrammetry: A case study of Hetao irrigation district in northern China

Most crops in northern China are irrigated, but the topography affects the water use, soil erosion, runoff and yields. Technologies for collecting high-resolution topographic data are essential for adequately assessing these effects. Ground surveys and techniques of light detection and ranging have good accuracy, but data acquisition can be time-consuming and expensive for large catchments. Recent rapid technological development has provided new, flexible, high-resolution methods for collecting topographic data, such as photogrammetry using unmanned aerial vehicles (UAVs). The accuracy of UAV photogrammetry for generating high-resolution Digital Elevation Model (DEM) and for determining the width of irrigation channels, however, has not been assessed. A fixed-wing UAV was used for collecting high-resolution (0.15 m) topographic data for the Hetao irrigation district, the third largest irrigation district in China. 112 ground checkpoints (GCPs) were surveyed by using a real-time kinematic global positioning system to evaluate the accuracy of the DEMs and channel widths. A comparison of manually measured channel widths with the widths derived from the DEMs indicated that the DEM-derived widths had vertical and horizontal root mean square errors of 13.0 and 7.9 cm, respectively. UAV photogrammetric data can thus be used for land surveying, digital mapping, calculating channel capacity, monitoring crops, and predicting yields, with the advantages of economy, speed and ease.

Detección de estructuras temporales en baloncesto Detection of temporal structures in basketball

Resumen: Resumir un partido de baloncesto a la efectividad en el lanzamiento, rebotes ofensivos y/o defensivos, entre otros indicadores; puede ser arriesgado, partiendo de la complejidad relacional existente en un partido de baloncesto. A pesar de ello, tradicionalmente ha sido investigado el éxito en baloncesto sobre datos sin una referencia temporal. La identiicación de regularidades temporales y conductuales puede ser un reto de investigación que ayude a concretar la planiicación de entrenamientos, así como la optimización estratégica de los equipos. El registro temporal de aciertos y fallos en el lanzamiento entre otros indicadores, puede ofrecer una dependencia temporal ineludible, invisible a una mirada aparente. Es este el propósito primordial del trabajo para optimizar las estrategias puestas en práctica en los partidos y con ello, la concreción de rutinas más ecológicas de acuerdo con las demandas de los partidos en los entrenamientos. Fue empleada una metodología observacional con un diseño nomotético, puntual y multidimensional para el registro de conductas motrices organizadas en torno a un sistema mixto de registro ‘had oc’. Para el análisis de la dimensión temporal de los registros fue empleada la técnica T-patterns (Magnusson, 2000), posibilitando así, la identiicación de asimetrías motrices. Los resultados muestran regularidades temporales y estratégicas más relevantes. La identiicación de itinerarios estratégicos de los equipos revelan la acomodación funcional entre los equipos. Palabras Clave: baloncesto, metodología observacional, t-patterns, interacción motriz Abstract: Summarizing a basketball game to efectiveness at launch, ofensive rebounds and / or defensive, among other indicators; it can be risky, based on the relational complexity existing in a basketball game. However, traditionally; it has been investigated success in basketball on data without a time reference. Temporary identiication and behavioral regularities can be challenging research to help realize training planning and strategic optimization of equipment. he temporary record of successes and failures in launching among other indicators, can provide an unavoidable time dependence, invisible to an apparent look. his is the primary purpose of work to optimize strategies implemented in matches and thus the realization of greener routines according to the demands of the parties in training. It was an observational methodology used a nomothetic, punctual and multidimensional design for the registration of motor behavior organized around a mixed system of registration ‘had oc’. For the analysis of the temporal dimension of the records it was used the technique T-patterns (Magnusson, 2000), thus enabling the identiication of motor asymmetries. he results show most relevant temporal and strategic regularities. he identiication of strategic pathways teams reveal functional accommodation between the teams.
Nonlinear Dynamics in a Complex Electrochemical System

This paper aims to offer a concise view of the nonlinear dynamics in electrochemical systems. Particular examples will be given using a model that qualitatively describes the anodic metal electrodissolution. Among the typical nonlinear behaviors exhibited by this system are bistable front propagation, periodic oscillations, standing waves, rotating pulses and chaotic dynamics.
On the congruence of some network and pom-pom models

We show that some network and pom-pom constitutive models are essentially the same. Instead of the usual confrontation, we suggest that the two approaches can offer useful mutual support: vital information about network destruction rates found from detailed pom-pom calculations can be used to improve the network models, while deductions about network creation rates can pinpoint areas needing further attention in the tube modelling area. A new form of the PTT model, the PTT-X model, results in improved shear and elongational flow descriptions, plus an improved recoil behaviour. The remaining problems of strain-time separation, second normal stress difference description, and reduction of parameters are also discussed and some suggestions for progress are offered.
Factors Affecting Teachers’ Use of ICTs in the Classroom: A Systematic Review of the Literature

ICT for education heralded much promise for improving learning outcomes, but results have not lived up to expectations. To understand why, researchers are increasingly exploring the factors that affect teachers’ acceptance and use of ICT in the classroom. This study adopts the systematic review approach used in clinical research to systematically search, screen, assess, and synthesize the literature on ICT use in classrooms and determine effect sizes, if any, of factors affecting teachers’ acceptance and use of ICT. We and that teachers’ perceptions about the usefulness of a particular technology are twice as important as their perceptions of the technology’s ease of use. We also and that two particular facilitating conditions—the provision of one laptop per child and on-site coaches—increased the use of technology by teachers by effect sizes ranging from 0.48 to 1.31.
Harmonic vibration of cusped plates in the N-th approximation of Vekua's hierarchical models

In this paper elastic cusped symmetric prismatic shells (i.e., plates of variable thickness with cusped edges) in the N -th approximation of Vekua’s hierarchical models are considered. The well-posedness of the boundary value problems (BVPs) under the reasonable boundary conditions at the cusped edge and given displacements at the non-cusped edge is studied in the case of harmonic vibration. The classical and weak setting of the BVPs in the case of the N -th approximation of hierarchical models is considered. Appropriate weighted functional spaces are introduced. Uniqueness and existence results for the variational problem are proved. The structure of the constructed weighted space is described and its connection with weighted Sobolev spaces is established.
Interactive comment on “ The sensitivity of global climate to the episodicity of fire aerosol emissions ” by S . K

First, thank you for a concise, well-written manuscript on a topic of significance for modelers wishing to constrain the effects of aerosols on the global weather and climate. Understanding the mechanisms that drive atmospheric forcing and their potential susceptibility to external forcing is a complicated science that is essential for predicting and therefore responding to climate change. The episodic nature of wildfire emissions is an important consideration when calculating the forcing effects of aerosols (as well as the chemical effects of trace gases released by fires).
Education and Training under Labor Market Frictions

I consider a frictional labor market model with ex-post wage bargaining where a worker invests in education ex-ante and a firm trains the employee. It is assumed that a fraction of the training cost is subsidized by the government and there exists complementarity between education and training. Although the worker and the firm face hold-up problems, the conditions under which efficiency is achieved can be derived. The conditions require that the government’s cost share to training should be equal to the worker’s bargaining share and also require that the elasticity of the production function with respect to education should be equal to the worker’s “effective” bargaining power. These conditions tell us what the government should do to gain efficiency. The model is extended to include education subsidies.
Interrelationships of Five Species of the Genus Labeo by Morphometric Analysis

The genus Labeo under Cyprinidae family is of much importance as many species under this genus are ornamental species, some food species, some used for extracting oil, some considered to be of medicinal value etc. Morphometric studies were conducted using eleven quantitative body parameters of five species of Labeo genus - Labeo bata, L.calbasu, L. rohita, L. pangusia and L. dyocheilus occurring from Assam, India, in order to identify the morphometric variation and taxonomic relationship among these species. All measurements were taken on a continuous scale using digital vernier caliper parallel to the anterior-posterior body axis except for the body depth that was taken perpendicular to the body axis between dorsal and ventral margins. The means of all measurements were standardized and multivariate cluster and principal component analysis were conducted using bdpro32 software. A dendrogram has been prepared showing the relatedness among the species. The results obtained on the basis of morphometric variation among the species using cluster analysis showed that L. bata is most distantly related whereas L. rohita and L. calbasu are most closely related with a similarity of 98.3965 (distance = 1.6035 ) followed by L. pangusia and L. dyocheilus . The scores of PC1, PC2 and PC3 are also most similar between L. rohita and L. calbasu. The findings of this study will help in developing new strategies for conservation and breeding programmes of these species.
Temporal and spatial variation in the distribution of life history phases of Chondrus crispus (Gigartinales, Rhodophyta) #

Thirty populations of Chondrus crispus Stackhouse from Nova Scotia were collected during the years 1993 to 2011. Taken from estuaries, wave exposed open coasts, high intertidal rock pools and shallow subtidal habitats, the populations were evaluated for relative abundance of tetrasporophytic and gametophytic life history phases. Over 2,800 thalli were characterized using the resorcinol-acetal test to distinguish the kappa- and lambda-carrageenan containing fronds of gametophytes and tetrasporophytes, respectively. These populations had gametophytes (mean confidence interval), with most populations having gametophyte : sporophyte ratios ranging from 2 : 1 to 9 : 1. No population had a dominance of tetrasporophytes, although two populations had 1 : 1 ratios. A meta-analysis of our data along with previously published accounts showed no significant changes in gametophyte dominance with respect to hypothesized gradients of wave exposure, salinity, or water depth. Significant changes occurred in ratios at five sites where replicate sampling occurred in different years. We conclude that C. crispus in Maritime Canada has a natural ratio of 3 : 1 or greater in stable conditions, and that lower ratios represent recovery from disturbance in which bare substratum is created that is subsequently colonized by carpospores from remaining gametophytic thalli.
CURRENT-FED SWITCHED INVERTER WITH COUPLED INDUCTOR FOR LOW VOLTAGE RENEWABLE SYSTEM

This paper presents a novel coupled inductor based high boost inverter topology which can be utilized in low voltage renewable systems where high voltage step-up is needed to interface with 110 Vt220 V AC systems. The proposed inverter possesses high boost ability with superior EMI immunity compared to a traditional voltage source inverter (VSI). Unlike the traditional VSI, the proposed inverter does not need dead time circuit for its switching signals as it utilizes shoot-through state of the inverter in its single-stage configuration. Insertion of shoot-through state also helps it to achieve high boost operation essential for renewable energy applications. The proposed inverter is derived from Current-Fed Switched Inverter topology. Apart from topology derivation, this paper describes the steady state analysis of the inverter and establishes the relation between input, DC-link, and AC output. An experimental prototype is built to validate the proposed inverter circuit. A 220 V (rms) AC is obtained from 52 V DC input to demonstrate its boost mode of operation.
Nostalgia narratives? Pejorative attitudes to welfare in historical perspective: survey evidence from Beveridge to the British Social Attitudes Survey

Jensen and Tyler (2015) have powerfully argued that 'anti-welfare commonsense', fuelled by negative political and media discourse stressing welfare dependency and deception, has buttressed support for social security reform in recent years. Along with many other academics they point to the hardening of public attitudes towards welfare state provision and how notions of the 'deserving' and 'undeserving poor' have been reintroduced into popular debates. We identify four distinct threads within this scholarship. First, there is an argument that public attitudes have shifted from an earlier post-war welfare imaginary and settlement to an anti-welfare consensus. Second, this hardening includes a growing prevalence of 'othering'. The third thread is the broadening of this moral and disciplinary gaze to include groups, such as disabled people, who until recently were not subject to the same amount of stigma as other types of benefit recipients. Fourth, is the impact of pejorative welfare discourses on the self-identity and attitudes of disadvantaged groups. While a growing body of evidence makes it increasingly difficult to argue against suggestions that there is a hostile body of anti-welfare sentiment in the UK, what is often implicit in the analysis of pejorative contemporary attitudes to welfare is the view that there was once a 'golden age' of the welfare state when public support was more fully behind a strong set of social security benefits provided as a social right of citizenship. Whether this was the case is a moot point however. Few studies have tried to piece together the attitudes to welfare of the general public during the consensus era. We attempt to undertake such a task here, drawing on ad hoc attitudes surveys and polling data in particular. Specifically, we focus on how notions of the 'deserving' and 'undeserving poor' play out in this data, pointing to some key continuities found in contemporary and historical public attitudes to welfare.
On relations between right alternative and nuclear square AG-groupoids

We find some interesting relations between right alternative and left nuclear square AG-groupoids such as (1) A right alternative AGgroupoid S is left nuclear square, (2) For a right alternative AG-groupoid S the conditions (i) S is right nuclear square, (ii) S is middle nuclear square, (iii) S is nuclear square, are equivalent, (3) a right alternative AG ∗∗ -groupoid S is nuclear square, and (4) a cancellative left nuclear square AG-groupoid S is T 1 -AG-groupoid.
Automatic adoption of touch as pointing modality on a touchscreen laptop: Beginners' motivators and inhibitors

Touch modality is a widely integrated and a highly desirable feature in modern interactive technological devices. It is the de-facto interaction modality in touchenabled mobile devices such as smartphones and tablets. Nowadays, the list of touchable interfaces is continuously expanding and even includes previously nontouchable devices such as laptops. Touch modality in laptops, however, does not stand out as the default modality for interacting with the device. Primarily, a laptop can be operated with either of the traditional point-and-click modality alternatives already present, the mouse and the trackpad. User studies on pointing modalities have generated little information on the automatic use of touch since these studies are often grounded on users’ preferential intentions, but rarely on the drivers that facilitate or impede the adoption of touch. This thesis endeavours to understand how certain factors such as background in touch usage, usage mode, type of pointing task, pointing targets and starting modality motivate or inhibit beginners’ automatic adoption of touch modality for activating interactive web elements on a touchscreen laptop device. An observation of users’ pointing movements was conducted in two sets of possible laptop usage mode – on a desktop and on a couch – with the aim of identifying the frequency of touches occurring as first instance. The observation aims to investigate the automatic adoption of touch by having participants perform pointing tasks on interactive web elements. The data obtained show that participants are motivated to automatically adopt touch within a more relaxed use context such as sitting on a sofa or on a playful task such as drawing. In conclusion, while there are not too many interactions on a touchscreen laptop which would necessitate the use of touch, its automatic adoption is, nevertheless, possible and has the potential to become widespread if user interfaces convey discoverable features of ‘touchability’ and if perceived worthiness of using touch overrides existing habitual usage of non-touch modalities.
A Review on Major Food Borne Bacterial Illnesses

Food borne illnesses are defined by the world health organization as diseases of infectious or toxic nature caused by consumption of contaminated foods or water. Food borne illnesses are classified in to two broad groups namely intoxication and infection. Intoxication is caused by ingestion of toxin produced by pathogens, while infection is caused by ingestion of food containing viable pathogens. Toxin can be present even when the bacteria or other causative agents are not and it is possible to develop food intoxication by eating animals that have consumed toxin producing organisms. Onset of illness is very rapid with food intoxication and people become very sick. The main causes of food borne illness are bacteria which constitutes 66% of the problems. Botulism, Clostridium perfringen gastro enteritis, E. coli infection, Salmonellosis and staphylococcal food poisoning are the major food illness caused by bacteria. Microorganisms present in food will grow under favorable conditions and will produce toxin in food. Following ingestion, toxins are absorbed through gastro intestinal epithelial lining and cause local tissue damage. In some cases toxins are translocated to distant organs or tissues such as kidney, liver, central nervous system or peripheral system where they can cause damage. The most common clinical symptoms of food borne illnesses are diarrhea, vomiting, abdominal cramps, headache and nausea. Food borne illnesses are usually diagnosed based on patient’s history and the symptoms. Food borne illness prevention system will depend on the extent of food safety control in place through food production, processing and distribution keeping food clean, separation of raw and cooked, and cooking thoroughly, keeping food at safe temperature and using safe water and raw materials are some of the important points especially for safety of food of humans. The high level of bacteria which could cause food borne illness in various foods presents public health risk to the consumer. This suggests the need to implement strict hygienic control measures along the food chain to improve the hygienic conditions during manufacturing, handling, storage and commercialization of foods.
Interlanguage speech recognition by computer : implications for SLA and computational machines

During the last decade, there has been a rapid growth in research into speech recognition by computer (SRC). Computerised voice recognition systems have been developed which are being used for a variety of applications. However there remain a whole range of issues which have to be elucidated and investigated before SRC can be broadly useful including for language learning purposes. It is well documented that speaker variability caused by accent is one of these issues and one of the major hurdles in accurate speech recognition. Foreign speaker recognition is particularly problematic to program for reasons that our work is beginning to suggest. In this paper we describe and compare the SRC of an interlanguage speaker of Italian/English versus a native speaker of English, both with repetitive strain disorder (RSD) and thus highly motivated, using the same software, DragonDictate, from Dragon Systems. Cognitive processes such as language transfer, fossilization and communication strategies are examined in light of the research. We illustrate the possibility of using SRC in second language research with particular emphasis on phonology. In this paper we not only explain our views of the potentials of this new technology in facilitating second language acquisition research but go to a more general applied linguistics issue where we briefly discuss some implications for the design of speech recognition systems for interlanguage speakers. This focus, we believe, can help make applied linguistics a main stream discipline, thereby increasing the job space for applied linguistics graduates.
