Creating Places of Public Memory through the Naming of School Buildings. A Case Study of Urban School Spaces in Bologna in the 19th and 20th Centuries
Authors: D’ascenzo Mirella
Published: November 2016

Esta contribución pretende analizar los nombres oficiales de las escuelas italianas en los siglos XIX y XX, teniendo en cuenta estas escuelas como lugares de memoria civil, política y escolar. Estudiando la legislación nacional y en base a la investigación histórica de escuelas específicas en Italia, el trabajo se centra en la denominación de los edificios escolares que se encuentran hoy en la ciudad de Bolonia (Italia), durante el período comprendido entre la Unificación y la Segunda Guerra Mundial. Examinando fuentes de archivo aún inexploradas, el artículo analiza las motivaciones subyacentes a los nombres de las escuelas, los contextos en los que se debatieron y decidieron, las ceremonias de inauguración y los discursos oficiales relativos dados por las autoridades, las piedras colocadas o bustos expuestos dentro o fuera las escuelas y la compleja escenografía establecida para la población local que ofrecen un discurso «pedagógica» y, sin embargo político, como un auténtico patrimonio educativo de la «memoria pública» y la pedagogía política para las generaciones presents y futuras. Este estudio también muestra algunas sorpresas interesantes en relación con las figuras y personajes, famosos y menos conocidos, señalados en la memoria local de la escuela, pero legibles en muchos niveles de interpretación histórica y educativa. Este trabajo ha confirmado que oficialmente el nombre de los edificios escolares italianos son auténticos lugares de la memoria asignadas desde su nacimiento para desempeñar una función civil y pública de la educación nacional y la memoria cultural, así como para la alfabetización de las nuevas generaciones.

Published: October 2016

The Karimunjawa Islands mangrove forest has been subjected to various direct and indirect human disturbances in the recent years. If not properly managed, this disturbance will lead to the degradation of mangrove habitat health. Assessing forest canopy fractional cover (fc) using remote sensing data is one way of measuring mangrove forest degradation. This study aims to (1) estimate the forest canopy fc using a semi-empirical method, (2) assess the accuracy of the fc estimation and (3) create mangrove forest degradation from the canopy fc results. A sample set of in-situ fc was collected using the hemispherical camera for model development and accuracy assessment purposes. We developed semi-empirical relationship models between pixel values of ALOS AVNIR-2 image (10m pixel size) and field fc, using Enhanced Vegetation Index (EVI) as a proxy of the image spectral response. The results show that the EVI provides reasonable estimation accuracy of mangrove canopy fc in Karimunjawa Island with the values ranged from 0.17 to 0.96 (n = 69). The low fc values correspond to vegetation opening and gaps caused by human activities or mangrove dieback. The high fc values correspond to the healthy and dense mangrove stands, especially the Rhizophora sp formation at the seafront. The results of this research justify the use of simple canopy fractional cover model for assessing the mangrove forest degradation status in the study area. Further research is needed to test the applicability of this approach at different sites.

Published: October 2016

In empirical approach, the satellite-derived bathymetry (SDB) is usually derived from a linear regression. However, the depth variable in surface reflectance has a more complex relation. In this paper, a methodology was introduced using a nonlinear regression of Random Forest (RF) algorithm for SDB in shallow coral reef water. Worldview-2 satellite images and water depth measurement samples using single beam echo sounder were utilized. Furthermore, the surface reflectance of six visible bands and their logarithms were used as an input in RF and then compared with conventional methods of Multiple Linear Regression (MLR) at ten times cross validation. Moreover, the performance of each possible pair from six visible bands was also tested. Then, the estimated depth from two methods and each possible pairs were evaluated in two sites in Indonesia: Gili Mantra Island and Panggang Island, using the measured bathymetry data. As a result, for the case of all bands used the RF in compared with MLR showed better fitting ensemble, -0.14 and -1.27m of RMSE and 0.16 and 0.47 of R2 improvement for Gili Mantra Islands and Panggang Island, respectively. Therefore, the RF algorithm demonstrated better performance and accuracy compared with the conventional method. While for best pair identification, all bands pair wound did not give the best result. Surprisingly, the usage of green, yellow, and red bands showed good water depth estimation accuracy.

Residential fires are a form of disaster that often occurs in urban areas especially in densely populated settlements. This study looks at possible mitigation scenarios for this kind of disaster. A case study was conducted in Babakan Ciparay Sub-District in Bandung City, among the densely populated settlements, and was focused especially on Sukahaji Village, a sub-unit of Babakan Ciparay, which is the most densely populated village in Bandung City with up to 234.14 people/ha. There have been six structural fires recorded from 2007 until 2010 occurring in Sukahaji. This study applied stratified random sampling as the preferred sampling technique and data collection method from a total population of 3,227 buildings. The data was then examined using risk analysis. The results have led to two intervention measures suggested as mitigation scenarios for residential fires that can be applied within the Sukahaji Village. The study concludes that mitigation measures through strengthening community capacity can be the principal option in reducing risk to fires in densely populated urban settlements.

In this paper, we describe the solutions developed to address key technical challenges encountered while building a distributed database system that can smoothly handle demanding real-time workloads and provide a high level of fault tolerance. Specifically, we describe schemes for the efficient clustering and data partitioning for the automatic scale out of processing across multiple nodes and for optimizing the usage of CPUs, DRAM, SSDs and networks to efficiently scale up performance on one node.

The techniques described here were used to develop Aerospike (formerly Citrusleaf), a high performance distributed database system built to handle the needs of today's interactive online services. Most real-time decision systems that use Aerospike require very high scale and need to make decisions within a strict SLA by reading from, and writing to, a database containing billions of data items at a rate of millions of operations per second with sub-millisecond latency. For over five years, Aerospike has been continuously used in over a hundred successful production deployments, as many enterprises have discovered that it can substantially enhance their user experience.
The MemSQL query optimizer

Published: November 2016

Real-time analytics on massive datasets has become a very common need in many enterprises. These applications require not only rapid data ingest, but also quick answers to analytical queries operating on the latest data. MemSQL is a distributed SQL database designed to exploit memory-optimized, scale-out architecture to enable real-time transactional and analytical workloads which are fast, highly concurrent, and extremely scalable. Many analytical queries in MemSQL's customer workloads are complex queries involving joins, aggregations, sub-queries, etc. over star and snowflake schemas, often ad-hoc or produced interactively by business intelligence tools. These queries often require latencies of seconds or less, and therefore require the optimizer to not only produce a high quality distributed execution plan, but also produce it fast enough so that optimization time does not become a bottleneck.

In this paper, we describe the architecture of the MemSQL Query Optimizer and the design choices and innovations which enable it quickly produce highly efficient execution plans for complex distributed queries. We discuss how query rewrite decisions oblivious of distribution cost can lead to poor distributed execution plans, and argue that to choose high-quality plans in a distributed database, the optimizer needs to be distribution-aware in choosing join plans, applying query rewrites, and costing plans. We discuss methods to make join enumeration faster and more effective, such as a rewrite-based approach to exploit bushy joins in queries involving multiple star schemas without sacrificing optimization time. We demonstrate the effectiveness of the MemSQL optimizer over queries from the TPC-H benchmark and a real customer workload.

Oracle Database In-Memory (DBIM) accelerates analytic workload performance by orders of magnitude through an in-memory columnar format utilizing techniques such as SIMD vector processing, in-memory storage indexes, and optimized predicate evaluation and aggregation. With Oracle Database 12.2, Database In-Memory is further enhanced to accelerate analytic processing through a novel lightweight mechanism known as
Dynamic In-Memory Expressions
(DIMEs). The DIME mechanism automatically detects frequently occurring expressions in a query workload, and then creates highly optimized, transactionally consistent, in-memory columnar representations of these expression results. At runtime, queries can directly access these DIMEs, thus avoiding costly expression evaluations. Furthermore, all the optimizations introduced in DBIM can apply directly to DIMEs. Since DIMEs are purely in-memory structures, no changes are required to the underlying tables. We show that DIMEs can reduce query elapsed times by several orders of magnitude without the need for costly pre-computed structures such as computed columns or materialized views or cubes.

Exploratory querying of extended knowledge graphs
Authors: Yahya Mohamed , Berberich Klaus , Ramanath Maya , Weikum Gerhard
Published: November 2016

Knowledge graphs (KGs) are important assets for search, analytics, and recommendations. However, querying a KG to explore entities and discover facts is difficult and tedious, even for users with skills in SPARQL. First, users are not familiar with the structure and labels of entities, classes and relations. Second, KGs are bound to be incomplete, as they capture only major facts about entities and their relationships and miss out on many of the more subtle aspects.

We demonstrate TriniT, a system that facilitates exploratory querying of large KGs, by addressing these issues of "vocabulary" mismatch and KG incompleteness. TriniT supports query relaxation rules that are invoked to allow for relevant answers which are not found otherwise. The incompleteness issue is addressed by extending a KG with additional text-style token triples obtained by running Open IE on Web and text sources. The query language, relaxation methods, and answer ranking are extended appropriately. The demo shows automatic query relaxation and has support for interactively adding user-customized relaxations. In both situations, the demo provides answer explanations and offers additional query suggestions.
Partial marking for automated grading of SQL queries

Published: November 2016

The XData system, currently being developed at IIT Bombay, provides an automated and interactive platform for grading student SQL queries, as well as for learning SQL. Prior work on the XData system focused on generating query specific test cases to catch common errors in queries. These test cases are used to check whether the student queries are correct or not. For grading student assignments, it is usually not sufficient to just check if a query is correct: if the query is incorrect, partial marks may need to be given, depending on how close the query is to being correct. In this paper, we extend the XData system by adding features that enable awarding of partial marks to incorrect student queries. Our system is able to go beyond numerous syntactic features when comparing a student query with a correct query. These features of our grading system allow the grading of SQL queries to be fully automated, and scalable to even large class sizes such as those of MOOCs.
A system for region search and exploration
Authors: Feng Kaiyu , Zhao Kaiqi , Liu Yiding , Cong Gao
Published: November 2016

With the increasing popularity of mobile devices and location based services, massive amount of geo-textual data (e.g., geo-tagged tweets) is being generated everyday. Compared with traditional spatial data, the textual dimension of geo-textual data greatly enriches the data. Meanwhile, the spatial dimension of geo-textual data also adds a semantically rich new aspect to textual data. The large volume, together with its rich semantics, calls for the need for data exploration. First, it has many applications to retrieve a region for exploration that satisfies user-specified conditions (e.g., the size and shape of the region) while maximizing some other conditions (e.g., the relevance to the query keywords of the objects in the region). Second, it is useful to mine and explore the topics of the geo-textual data within a (specified or retrieved) region and perhaps a timespan. This demonstration proposal presents the main ideas of our system, the RegIon Search and Exploration System (RISE), for efficiently supporting region search and exploration, and our demonstration plan.

Leave no valuable data behind
Authors: Dong Xin Luna
Published: November 2016

With the mission "leave no valuable data behind", we developed techniques for knowledge fusion to guarantee the correctness of the knowledge. This talk starts with describing a few crazy ideas we have tested. The first, known as "Knowledge Vault", used 15 extractors to automatically extract knowledge from 1B+ Webpages, obtaining 3B+ distinct (subject, predicate, object) knowledge triples and predicting well-calibrated probabilities for extracted triples. The second, known as "Knowledge-Based Trust", estimated the trustworthiness of 119M webpages and 5.6M websites based on the correctness of their factual information. We then present how we bring the ideas to business in filling the gap between the knowledge at Google Knowledge Graph and the knowledge in the world.
Quill

Published: November 2016

This paper introduces Quill (stands for a
quadrillion tuples per day
), a library and distributed platform for relational and temporal analytics over large datasets in the cloud. Quill exposes a new abstraction for parallel datasets and computation, called
ShardedStreamable
. This abstraction provides the ability to express efficient distributed physical query plans that are transferable, i.e., movable from offline to real-time and vice versa. ShardedStreamable decouples incremental query logic specification, a small but rich set of data movement operations, and keying; this allows Quill to express a broad space of plans with complex querying functionality, while leveraging existing temporal libraries such as Trill. Quill's layered architecture provides a careful separation of responsibilities with independently useful components, while retaining high performance. We built Quill for the cloud, with a master-less design where a language-integrated client library directly communicates and coordinates with cloud workers using off-the-shelf distributed cloud components such as queues. Experiments on up to 400 cloud machines, and on datasets up to 1TB, find Quill to incur low overheads and outperform SparkSQL by up to orders-of-magnitude for temporal and 6× for relational queries, while supporting a rich space of transferable, programmable, and expressive distributed physical query plans.

The new Common Agricultural Policy (CAP) has been designed to shrink funds that Hungarian agricultural reform will in Nowadays, anti-hail nets are a part of basic equipment in a modern apple orchards. They decrease the risks of apple production and thus allow regular and quality apple harvest. Colours of nets differently obstruct the passing of light through the net, which directly affects some quality parameters of the yield, especially the fruit skin colour. The article includes a brief overview of studies associated with the impact of light exposure under different types of anti-hail nets on quality of apple fruits, as well as investigations which deal with adaptation of various technological measures, such as the use of reflective ground foil. A part of data from the existing literature explains the effect of anti-hail net usage on forming a microclimate under the net, and consequently, its effect on the development and dynamics of diseases and pests.

Published: November 2016

The primary aim of this research study was to model acoustic conditions of the Courtyard of the Gdańsk University of Technology Main Building, and then to design a sound reinforcement system for this interior. First, results of measurements of the parameters of the acoustic field are presented. Then, the comparison between measured and predicted values using the ODEON program is shown. Collected data indicate a long reverberation time which results in poor speech intelligibility. Then, a thorough analysis is perform to improve the acoustic properties of the model of the interior investigated. On the basis of the improved acoustic model two options of a sound reinforcement system for this interior are proposed, and then analyzed. After applying sound absorbing material it was noted that the predicted speech intelligibility increased from bad/poor rating to good category.
Acoustic Scattering of 3D Complex Systems Having Random Rough Surfaces by Scalar Integral Equations
Authors: Guel-Tapia Juan Antonio , Villa-Villa Francisco , Mendoza-Suarez Alberto , Pérez-Aguilar Hector
Published: November 2016

We propose a numerical surface integral method to study complex acoustic systems, for interior and exterior problems. The method is based on a parametric representation in terms of the arc’s lengths in curvilinear orthogonal coordinates. With this method, any geometry that involves quadric or higher order surfaces, irregular objects or even randomly rough surfaces can be considered. In order to validate the method, the modes in cubic, spherical and cylindrical cavities are calculated and compared to analytical results, which produced very good agreement. In addition, as examples, we calculated the scattering in the far field and the near field by an acoustic sphere and a cylindrical structure with a rough cross-section.
Media convergence and publicness: Towards a modular and iterative approach to online research ethics
Authors: Spilioti Tereza
Published: November 2016

The aim of the article is to build a bridge between assumptions about publicness and ethics in traditional (mass) media research and similar issues pertaining to research ethics in so-called new media environments. The article starts off with unpacking ‘publicness’ as defined in authoritative ethical guidelines that regulate research on (and through) media. It points to the challenges media convergence–and, particularly, the increasingly multimodal, multiauthored and multimedial content of websites–have brought to perceptions of publicness, as previously understood in mass media research. With reference to language-focused research on multilingual digital writing in such contexts, I critically engage with ethical tensions related to collecting and analysing internet data, on the one hand, and presenting and publishing data extracts from new media contexts, on the other. Drawing on modularity as a key organising principle of web design and discourse, the article proposes a modular and iterative approach to research ethics that takes into account the complex and fluid configuration of web environments and attends to the conditions of multiple authorship and multiple publics that are increasingly typical of such contexts.
Risk-Averse Managers, Labour Market Structures, Public Policies and Discrimination
Authors: Picault Julien
Published: November 2016

This article presents a model to analyze the effects of first and second-moment statistical discrimination on the labour market. Second-moment statistical discrimination occurs when risk-averse managers make decisions regarding wage and hiring based on productivity variances. We provide a framework exploring managers’ discrimination based on differences in average productivity and in variance of productivity. Furthermore, since discrimination is composed of two types (wage and hiring discrimination), our model allows for the interdependence between hiring practices and wages. Using our model, we examine the effects of various anti-discrimination policies along with changes to the labour market structure. We show that managers’ behaviour may be driven by anti-discrimination policies and labour market structures. A firm reduces hiring when required to implement anti-discrimination policies to address wage inequality. A firm applying policies to promote employment equity must stimulate minority participation. A change in labour market structure does not alter the efficiency of policies promoting employment equity, but it does alter the efficiency of policies aimed at reducing wage differences.

This experiment examined the influence of two different silage additives of biological (Lactococcus lactis, Lactobacillus plantarum, Enterococcus faecium, enzyme xylanase) and chemical (43% formic acid, 30% ammonium formate, 10% propionic acid, 2% benzoic acid) types on biogenic amines concentration, nutrient content, fermentation process, and microbiologic indicators in lucerne (Medicago sativa) silage after 90 days of fermentation. The biological additive significantly (P < 0.05) increased putrescine (+51%), lactic acid (+11%) and protein content (+11%) in comparison with control silage. It significantly decreased cadaverine (−29%), histamine (−57%), spermidine (−15%), spermine (−55%), acetic acid (−40%), ethanol (−55%), ammonium (−25%) and ash (−9%). After the chemical-additive treatment, greater amounts of histamine and tyramine were recorded. Significant decrease was observed in the concentrations of putrescine (−18%), cadaverine (−55%), spermidine (−47%), spermine (−45%), lactic acid (−16%), acetic acid (−46%), ammonium (−59%), ash (−13%) and fat (−24%). Populations of bacteria associated with lactic acid fermentation, moulds, yeasts, enterobacteria and total microorganisms count were also influenced. Both biological and chemical additives can be highly recommended for producing high-quality silages meeting hygienic requirements. In lucerne silage, the chemical preservative showed a stronger effect in achieving the health safety of silage compared to the biological inoculant.

Media and Violence. Closing one Door: Opening Another
Authors: Field Martin
Published: November 2016

This article sets the debate about the effects of media violence in the context of broader media research. A direct and simple ‘cause and effect’ model between media violence and violence in society does not stand up to scrutiny. It relies on an obsolete model of media influence which stands outside current, theoretical developments in mass communication research. It has diverted attention away from more relevant accounts which see the media as having ‘a primary function’ of ‘legitimation and maintenance of authority’. These suggest a no less powerful but infinitely more subtle model of media influence which finds wide support in other areas of mass communication research. Ironically, since popular debate about media violence has been – and still is – based almost exclusively upon experimental research, it too seems to serve this same legitimation process.
Sex in the Newsroom: Male-Female Differences in Perceptions of Media Professionalism
Authors: Okigbo C.C.
Published: November 2016

It is generally believed that the mass media are biased against women in terms of employment and news treatment. The roots of such bias are historical, and its effects arc felt in both the developed and developing countries. But this bias notwithstanding, are women journalists different from their men counterparts with respect to their views on media professionalism? To answer this question, data were collected from men and women Nigerian journalists who were asked their views on various aspects of media professionalism. The analysis of the data showed no significant differences between men and women journalists with respect to perceptions of media professionalism. This paper provides empirical support for equal treatment of the sexes in journalism.
Das Thema Tierversuche im Fernsehen - Meinungs-(Angst)mache durch Manipulation
Authors: Vogt Michael
Published: November 2016

Zusammenfassung der Diskussion

Bereits vor Beendigung des Vortrages durch Dr. Vogt entwickelte sich eine teilweise sehr emotional geführte Diskussion. Hierbei standen zunächst Fragen nach der Notwendigkeit von Tierversuchen in der pharmakologischen Forschung im Mittelpunkt und weniger die kommunikationswissenschaftlichen Aspekte. Dr. Vogt machte darauf aufmerksam, daß im vergangenen Jahr kein einziges Medikament auf synthetisch-chemischer Basis vom Bundesgesundheitsamt zugelassen wurde, ohne daß zuvor Tierversuche mit diesem Wirkstoff durchgeführt worden waren. Auch wenn die gesamte Pharmaindustrie rund 4000 Katzen pro Jahr für derartige Untersuchungen brauche, sei es nicht richtig, die jährlich 100.000 verschwindenden Katzen in entsprechenden Labors zu vermuten.

Es bestand Konsens darüber, daß Medien Realität konstruieren. Dies gelte für alle Themen. Aus der Sicht des Referenten werde allerdings bei der Realisation des Themas Tierversuche bewußt eine Realitätsfälschung durch die entsprechende Zusammensetzung und Dramaturgie von Diskussionsrunden oder durch die Vermischung von Fiktion und Wirklichkeit in Dokumentationssendungen konstruiert. Medienvertreter aus dem Publikum warfen daraufhin dem Referenten vor, daß er Meinungen manipulieren wolle, indem er Sendeversatzstücke aus dem Zusammenhang reiße und diese in seinem Sinne und zum Nachweis seines Verständnisses von verfehlter journalistischer Arbeit dem Publikum präsentiere.

Es wurde abermals deutlich, daß die grundsätzliche Diskussion über Tierversuche sehr stark polarisiert: der „weiße Riese“ Pharmaindustrie auf der einen und die armen Tiere auf der anderen Seite. Diese Polarisierung sei nur mit dialogischer Kommunikation und einer Rückbesinnung der Vertreter aus Pharmaindustrie und Medien auf ethische Grundwerte wie Solidarität, Altruismus und Gemeinwohl aufzulösen.
Catalytic Sol Assisted Dense Pd/γ-Al2O3 Membrane using Modified Electroless Plating: Effect of Process on Surface Morphology
Authors: Sharma Richa , Kumar Amit , Upadhyay Rajesh K.
Published: November 2016

Palladium membranes are considered ideal for high purity hydrogen separation owing to their infinite selectivity to hydrogen. The key to such selectivity depends on the dense surface of the membrane that suggests absolute non-porous surface morphology. However, preparation of dense palladium membranes irrespective of any deposition technique leads to pit formation which makes synthesis of dense palladium membrane challenging. The current study illustrates the application of electroless plating assisted with novel catalytic sol pre-coating to prepare dense Pd membranes. The surface characterization using field emission scanning electron microscope (FESEM) and atomic force microscopy (AFM) were performed to identify the gaps between dip coating and electroless plating. It was observed that with the use of a dip coated catalytic sol, thinner and well dispersed Pd deposits could be prepared. The porosity of deposited Pd layers does not affect the essential densification property as sol surface underneath dispersed Pd remains dense.

On asymptotic properties of the distribution of the number of pairs of H-connected tuples
Authors: Mikhailov V. G.
Published: November 2016

The main result of this paper is a theorem about convergence of the distribution of the number of pairs of H-connected s-tuples in two independent sequences of independent identically distributed variables. The concept of H-connection is a generalisation of the concept of H-equivalence of tuples. We give sufficient conditions for convergence and an explicit estimate of the rate of convergence. We use the local variant of the Chen-Stein method for estimating the accuracy of Poisson approximation for distribution of the set of dependent random indicators. The main results of this paper were announced in [7].

A family of multivariate χ2-statistics
Authors: Selivanov B. I.
Published: November 2016

We consider a sequence of independent trials, which, under the hypothesis H0, is a realisation of some polynomial scheme. We define a family of multivariate chi-square statistics which includes the sequential chi-square test statistics. We formulate conditions which guarantee that the distributions of the statistics under consideration converge to limit distributions under the hypothesis H0 and the alternatives contigual to H0. We find the form of the Laplace transforms of the limit distributions of the statistics of the family.

Twenty-First Century “Populism:” Not for the Unions and a Good Thing Too
Authors: Lichtenstein Nelson
Published: November 2016

On both the left and the right the phrase “populism” has lost any tangible meaning; or rather it is the default word used to describe otherwise unorganized and atomized anti-elite sentiment of almost any sort. The labor movement is a genuinely anti-corporate and anti-elite effort to empower workers both white and of color, but few commentators describe it as “populist,” and correctly so. This is because trade unions have an organized leadership, a concrete program, and the capacity to exist once the fever of the election season has passed. In his campaign for the Democratic presidential nomination, Bernie Sanders largely missed the much needed opportunity to defend and legitimize these working-class institutions for millions of potential members.

Published: November 2016

This paper presents a miniaturized frequency selective surface (FSS) with stop band characteristics at the resonant frequency of 5.12 GHz. The unit cell size of the proposed FSS design is in the order of 0.095 λ×0.095 λ. The proposed unit cell is obtained by convoluting the arms of the basic swastika structure. The design provides fractional bandwidth of 9.0 % at the center frequency of 5.12 GHz in the 20 dB reference level of insertion loss. The symmetrical aspect of the design delivers identical response for both transverse electric (TE) and transverse magnetic (TM) modes thereby exhibiting polarization independent operation. The miniaturized design provides good angular independency for various incident angles. The dispersion analysis is done to substantiate the band stop operation of the convoluted swastika FSS. The proposed FSS is fabricated and its working is validated through measurements.

Published: November 2016

In this paper, a novel multilayered substrate integrated waveguide (SIW) composite right/left-handed (CRLH) structure is proposed to design beam scanning antenna for wideband broadside radiation. The unit cell of the SIW-CRLH structure is formed by spiral interdigital fingers etched on the upper ground of SIW, and a parasitic patch beneath the slot, has a continuous change of phase constant from negative to positive value within its passband. The proposed beam scanning antenna, which consists of consists of 15 identical elementary cells of the SIW-CRLH, is simulated, fabricated and measured. According to the measured results, the proposed antenna not only realizes a continuous main beam scanning from backward –78° to forward +80° within the operating frequency range from 8.25 to 12.2 GHz, but also obtains the measured broadside gain of 11.5 dB with variation of 1.0 dB over the frequency range of 8.8–9.25 GHz (4.99 %). Besides, compared with the same works in the references, this one has the most wonderful performance.
The Fate of the Award Annulled in the Country of the Seat
Authors: Sardu Alessandra
Published: November 2016

The topic of the fate of the award annulled in the legal order of the seat has always been at the center of fervent debates. Once annulled, does the award cease to exist? Is it correct to speak about the extraterritorial and erga omnes effects of the judgment of the courts of the seat annulling the award? Scholars and national courts have tried to give an answer to these questions finding a possible solution in the framework of the New York Convention. However, it is doubtful whether the New York Convention addresses this issue. This article aims at exploring in a critical manner the different theoretical views on the fate of the award annulled in the country of origin, also taking into account case law of national courts on the topic. Three theoretical theses are analyzed and compared. A first thesis affirms that (i) an award annulled in the country of the seat cannot be enforced anywhere else, a second that (ii) the courts of the enforcement States have discretion in deciding whether to grant recognition and enforcement to a foreign award and a third that (iii) the annulment of an award in the State does not constitute a ground to refuse the enforcement of the award.
The Application of Multimedia at the Lecture-experimental Tours at Secondary Schools
Authors: Holá Oľga
Published: November 2016

The lecture-experimental tours at secondary schools of Slovakia have been realized within the scope of the APVV (The Slovak Research and Development Agency) project solving: “Physics and Chemistry in our Life Today and Tomorrow”. These lectures consist of lectures supported by power-point presentations, illustrative demos of lectured problems, as well as simple experiments. In the lecture part various information and communication means are used - e.g. the Internet connection, various CDs, DVDs and our own video film library. In our paper we inform of these courses and of their objectives and responses.
Question Objects – Source of Electronic Questions
Authors: Hrubý Miroslav
Published: November 2016

The high quality electronic tests and self tests should be an indispensable part of modern study materials and study environment. The described theory says that the items of electronic tests and self tests are electronic questions and that every electronic question is generated by the so called question object. Each question object belongs to one of the defined types. The main goal of this paper is to introduce a prepared formal description and describe the set of useful types of electronic question objects regardless of their connection with the existing software. The author tries to bridge the possible gap between the educational needs and the range of various types of available software.
Adaptive Form of Elearning

Published: November 2016

Among classic and electronic forms of education, a new type is being considered - the individualised form of education. The main reasoning behind individualised education is to respect differences of individual students. This individualised form of education in connection with the ever-present ICT devices leads to a new form of education - adaptive eLearning: a form of educational process that is in harmony with individual needs of students. This article deals with the basic principles of creating adaptive learning environment; with the current conditions of this issue in the Czech Republic and abroad; and with the outline of possible solutions to the adaptive electronic teaching process. In the second half of the article, the structure of adaptive study aids is described in detail.
Optimizing Video Clips in Educational Materials
Authors: Oujezdský Aleš
Published: November 2016

The use of videos from digital camcorders has become a standard in education in recent years. The curriculum is easily accessible and appeals to a wider audience. The lessons use videos of various physical processes and chemical experiments. However there can be problems with this format. The video quality is often degraded in the final stage when the video is being prepared for placement in education. These include teaching materials in the form of web pages, elearning courses or flash multimedia objects. The final product of editing video from a digital camcorder is a DVD video. However, if we want to transfer this to the Web or other educational material, it is necessary to remove non-square pixels, interlaced video and choose the appropriate compression. For these operations, there are many interpolation algorithms (nearest neighbour, bilinear interpolation, bicubic interpolation), filter deinterlacing (wave, bob, blend), and compression tools. By selecting appropriate settings for these parameters, the video material can be optimized while maintaining the highest possible image quality. The final step before publishing the video is its conversion into one of the used codecs. Codec’s settings will largely impact the final quality and size of the video-clip.
