Published: May 2015

The set-top box (STB) connected to TVs are used to gather viewing data, which then is transmitted to a backend platform. It is very hard to analyze the viewing behavior since the viewing data are very huge and contain noise. This paper presents a real-time interactive-TV rating system for monitoring the trend of user viewing behavior. The system collects viewing behavior data from CATV system vendors, analyzes the data, and then provides real-time analysis diagrams. The authors also proposed two phases filtering algorithm that can efficiently check and filter the invalid viewing behavior according to the effective data filter rules. The algorithm can daily filter 27 million viewing behavior data and generate 7.6 million effective data. It can reduce the need of storage space and increase the analysis speed. In this works, we develop a real-time interactive-TV rating system for monitoring the trend of user viewing behavior and provide the real-time ratings for the last three minutes watched.

Authors: Chiu Yung Piao , Shiau Yan Chyuan , Song Shu Jen
Published: May 2015

The main rivers in Taiwan present numerous distinct features, such as narrow catchment areas, short main flow paths, fast-flowing rapids, and steep slopes. In Taiwan, typhoon season in summer and fall is the period during which torrential rainfall frequently occurs. Large amounts of rainfall in short periods increase the likelihood of disasters, such as hillside collapses, landslides, and floods. By using a computer simulation to visually present landslide disasters, disaster evacuation can be facilitated and casualties can be reduced. In the present study, we compiled the causes of hillside landslides by employing a remote helicopter equipped with a camera to capture images of landslide-prone rivers and hillsides. ReCap computation was adopted to establish 3D river and hillside models for mesh optimization, which were then imported into the Unity software. Finally, by referencing slope and geographical data, and considering various landside factors such as cause, scale, flow direction, flow speed, and damage, model disaster scenarios were created to perform simulations. The results were uploaded to Web-and mobile-based platforms, providing a reference for assisting the general public in implementing preventive measures, thereby reducing the occurrence of disaster incidents.

Authors: Su Chung Ho , Chen Ken T.K.
Published: May 2015

Researchers of game-based learning have often suggested that learner’s motivation beliefs about learning achievement would likely affect their use of game-based learning strategies and ultimate success in learning. However, research which has empirically documented the link between gamification, motivation, and cognitive load is scant. Therefore, the aim of this article attempts to explore how gamification, motivation, cognitive load will affect learning achievement, and their use of Gamification Software Engineering Education Learning System (GSEELS) are related. This research involved empirical study, comprised of four sets of questionnaires concerning gamification, motivation; cognitive load and learning achievement. Tow intact class of 107 college students participated in the study. The structural equation modeling (SEM) analysis was conducted through descriptive statistics, measurement model evaluation and structured model evaluation in order to indicate the direction and relationship between the four sets of variables. The research result shows that 5 out of 6 hypotheses are supported and merely 1 hypothesis is false. Well-design GSEELS will affect student learning motivation and achievement. To conclude, this study may be important in explaining the relationship between gamification, motivation, cognitive load, as well as in suggestions for teaching and learning four aspects with a better understanding of how teacher’ beliefs about SE education related to their strategy use.

Authors: Chen Young Long , Chang Yung Chi , Zeng Yu Ling
Published: May 2015

Wireless sensor networks (WSNs) are a group of wireless sensor nodes, those sensor nodes with sensing and monitoring of environmental information. Energy consumption is an important topic; the node's power is limited. Therefore, we proposed an Opportunistic Large Array Concentric Geographic Routing Algorithm (OLACGRA) to reduce the node’s energy consumption and analysis the characteristic of energy model. The sink position of our proposed OLACGRA is at the center of concentric topology architecture. The source node wants to transmit data that it needs to calculate the distance between source node and sink node. If this distance bigger than threshold value, we use the multi-hop manner. Otherwise, source node transmits data to sink node directly. Simulation results show that our proposed algorithm can effectively reduce the node’s energy consumption.

Authors: Lee Yung Cheng , Lee Pei Ju
Published: May 2015

Due to the rapid growth of computer and communication technologies, people obtain variety of online services quickly. However, all networks are vulnerable to lots of security threats and attacks. The remote authentication scheme provides an efficient method to validate the remote users and servers. Ahirwal and Sonwanshi proposed a remote user authentication scheme with smart card in 2012. They indicated that Song’s smart card based password authentication protocol cannot resist the offline password guessing attack, insider attack, forward secrecy and denial of service attack. They proposed an ID-based authentication scheme to fix security flaws. The scheme uses one-way hash function and bitwise XOR operation such that the computation complexity is very low. However, in this article, we will show that their scheme cannot withstand the offline password guessing attack as they declared. An adversary can use the intercepted messages of two login sessions to obtain the password.

ET Detector: A Client-Based Solution to Detect an Evil Twin Access Point
Authors: Hsneh Yu Hsiang , Hsu Fu Hau , Chen Shih Jen , Chen Yao Hsin , Hwang Yan Ling , Wang Chuan Sheng , Hsu Yu Liang
Published: May 2015

An evil twin is a kind of rogue Wi-Fi access point (AP) which has the same SSID name to the legitimate one and is set up by an adversary. The user who associates to the evil twin, adversary may eaves-drops sensitive data on wireless communications to the Internet. Most of existing detection solutions are administrator-based, which is used by wireless network administrator to verify whether a given AP is in an authorized list or not. Such administrator-based solutions are limited, hardly maintained, and difficult to protect users timely when the attack is launched. Hence, we propose a client-based detection by operating the wireless network interface controller (WNIC) in monitor mode and capturing the Internet packets. Through analyzing the captured packets, client users can easily and precisely detect the evil twin attack even in a complicated AP scenario as well as avoid any threat arisen from connecting to an AP. Our method does not need to know any authorized AP list, and does not rely on data training or machine learning technique of target wireless network. Finally, we implemented a detecting system on Windows 7, which is widely used nowadays.

Published: May 2015

Traffic counts are one of the fundamental data sources for the Highway Performance Monitoring System (HPMS). Automatic Traffic Recorders (ATRs) are used to provide continuous traffic count coverage at selected locations to estimate annual average daily traffic (AADT). However, ATR data is often unavailable. This paper investigated the feasibility of using Video Detection System (VDS) technology when ATR data is not available. An Android Tablet-based manual traffic counting application was developed to acquire manual count based ground truth data. The performance of VDS was evaluated under various conditions including mounting styles, heights, and roadway offsets. The results indicated that VDS data presents reasonably accurate data, although the data exhibits more variability compared to ATR data.

On the Performance of Weakly Connected Dominating Set and Loosely Coupled Dominating Set for Wireless Sensor/Mesh Networks
Authors: Dou Chie , Chang Yu Hui , Ruan Jia Siang
Published: May 2015

Using an underlying cluster-based virtual backbone induced by the weakly connected dominating set (WCDS) is a very promising approach to enhance network efficiency. This paper proposes a novel loosely-coupled dominating set (LCDS) which is adapted from the concept of WCDS by further relaxing its connectivity requirement. The main advantages of the proposed LCDS are as follows. First, it can further reduce the size of the dominating set compared with that generated by the WCDS. Second, it can decrease the average utilization of the selected cluster heads to prolong their life-cycle. Third, it can increase the edge coverage of the network to exploit the benefits of load balancing. Fourth, it provides the network with high reliability by supporting more alternative routing paths. Numerical results show that the proposed LCDS outperforms the WCDS in almost every node deployment scenarios and every performance aspects.

This paper proposed a spelling error detection and correction using the linguistic features and knowledge resource. The linguistic features mainly come from language model that describes the probability of a sentence. In practice, the formal document with typos is defective and fall short of the specifications, since typos and error hidden in printed document are frequent, rework will cause the waste of paper and ink. This paper proposed an approach that addresses the spelling errors and before printing. In this method, the linguistic features are used in this research to compare and increase a new feature additionally that is a function of Internet search based on knowledge bases. Combining these research manners, this paper expect to achieve the goals of confirming, improving the detection rate of typos, and reducing the waste of resources. Experimental results shows, the proposed method is practicable and efficient for users to detect the typos in the printed documents.

Toward a Unified Approach to Software Reliability Modeling under Imperfect Debugging
Authors: Lo Jung Hua
Published: May 2015

Many software reliability growth models (SRGMs) have been developed to estimate some useful measures such as the mean value function, number of remaining faults, and failure detection rate. Most of these models have focused on the failure detection process and not given equal priority to modeling the fault correction process. But, most latent software errors may remain uncorrected for a long time even after they are detected, which increases their impact. The remaining software faults are often one of the most unreliable reasons for software quality. Therefore, we develop a general framework of the modeling of the failure detection and fault correction processes. Furthermore, it is assumed that a detected fault is immediately removed and is perfectly repaired with no new faults being introduced for the traditional SRGMs. In reality, it is impossible to remove all faults from the fault correction process and have a fault-free effect on the software development environment. In order to relax this perfect debugging assumption, we introduce the possibility of imperfect debugging phenomenon. Finally, numerical examples are shown to illustrate the results of the unified approach for integration of the detection and correction process under imperfect debugging.

Published: May 2015

A numerical comparison of finite difference (FD) and finite element (FE) methods for a stochastic ordinary differential equation is made. The stochastic ordinary differential equation is turned into a set of ordinary differential equations by applying polynomial chaos, and the FD and FE methods are then implemented. The resulting numerical solutions are all non-negative. When orthogonal polynomials are used for either continuous or discrete processes, numerical experiments also show that the FE method is more accurate and efficient than the FD method.

Towards a Methodological Approach for Frame Identification and Analysis in Translation
Authors: Dejica Daniel
Published: May 2015

Frame analysis is a relatively new methodological approach which shows how people understand activities or situations. It originated in sociology and its application to translation has not been considered practically or theoretically yet, though the advantages may be manifold. Consisting of two main parts, this paper presents a methodology for frame identification and analysis, and suggests this be applied to the translation of pragmatic texts. The first part presents the concepts of frame and frame analysis as they appear in literature and as they are interpreted in this paper for translation purposes. $e second part focuses on the exemplification of a methodological framework which includes the integration of frames into the translation process. It is shown that by using frames, translators can obtain the cognitive image of the text, create various versions of the source text in the target language, and use translation strategies consistently and transparently.
The Present Perfect and Preterite in British and American English
Authors: Žetko Katarina Dea
Published: May 2015

The objective of our article is to present the selected results of the research which was conducted for the purpose of our master’s thesis. We focused on the transfer of the functions of the present perfect into the domain of the preterite in informal British and American English. We put together a British and an American corpus and analysed the differences and similarities between British and American English in this transfer. We examined some factors that may influence this transfer either in American or British English, or in both varieties. The major factors will be presented in this article. The results show that the differences between both varieties mostly occur in the frequency of this transfer. Moreover, in American English there are more significant factors than in British English. Nevertheless, we can observe that the general tendency is the same in both varieties. This fact may indicate that this phenomenon, which was first noticed in informal American English, is spreading to informal British English.
Teaching Reference Skills: Does it really Matter?
Authors: Kavalir Monika
Published: May 2015

The article discusses the results of a study at the core of which is the question of whether teaching reference skills really matters – i.e. how useful it is to train students to work with dictionaries. To answer this query, two issues are investigated: firstly, how effective the particular methodology developed here is with regard to using thesauri; and secondly, whether it makes a difference if some specific hands-on exercises are included or excluded. By the end of the project, the students felt that thesauri, a previously unknown language tool, would be quite useful for their work in the future; on average, they were planning to use a thesaurus several times a month. The analysis of the student questionnaires and a comparison of lexical variation in the first and second drafts of the essays also showed that the experimental group, which received more practical training, generally found thesauri more useful and, accordingly, used them more than the control group did.
Carniola oživljena: Spreminjajoča se praksa pri poimenovanju slovenskih pokrajin v angleških besedilih
Authors: Reindl Donald F.
Published: May 2015

V zadnjem stoletju smo bila priča izrazitim spremembam v poimenovanju tradicionalnih slovenskih pokrajin v angleških besedilih. Po drugi svetovni vojni so Slovenci že ustaljene angleške eksonime za te pokrajine v angleških besedilih postopoma zamenjali z endonimi. Tej smeri razvoja so sledila tudi objavljena dela in pedagoška praksa, ki so vedno bolj vztrajali pri tem, da se v angleških besedilih uporabljajo izključno endonimi. Po razpadu Jugoslavije in osamosvojitvi Slovenije pa so se ustaljeni eksonimi začeli ponovno uporabljati. Članek orisuje to spreminjajočo se prakso na podlagi izbranih angleških besedil iz zadnjih treh stoletij. Poleg tega se osredotoča tudi na številne probleme, povezane z rabo endonimov, ter na nenehna vprašanja glede rabe endonimov. Ker je angleščina svetovni jezik, izbire tistih, ki pišejo v angleščini, neposredno vplivajo na to, kako sta Slovenija in slovenska narodna identiteta predstavljeni na svetovni ravni. Zaključki se nanašajo neposredno na prakso prevajanja slovenskih besedil v angleščino, posredno pa tudi na slovensko književnost in kulturo, predstavljeno v angleških prevodih.
Deconstructing Identity in Postcolonial Fiction
Authors: Karkaba Cherki
Published: May 2015

With the destabilization of political and cultural boundaries between peoples and nations, the concept of identity, with its implications in the dialectics of self and other, becomes a philosophical challenge in a globalised cosmopolitan world. The challenge resides in the fact that in such a postmodern situation where identity is viewed as shapeless, shifting and moving beyond the fixity of Manichean thought, a process of questioning is enacted to interrogate identity in its past, present and future implications. This paper will attempt to look at the ways in which some postcolonial novels set out to deconstruct the concept of identity by constructing ambivalent texts, blurring the borders between self and other, laying the foundations for hybridity where otherness reigns as a process of signification which rests on interpretation.
Slovene-English Language Contact and Language Change
Authors: Šabec Nada
Published: May 2015

The paper focuses on Slovene - English language contact and the potential language change resulting from it. Both the immigrant context (the U.S. and Canada) and Slovenia, where direct and indirect language contact can be observed respectively, are examined from two perspectives: social on the one hand and linguistic on the other. In the case of Slovene Americans and Canadians the emphasis is on language maintenance and shift, and on the relationship between mother tongue preservation and ethnic awareness. The linguistic section examines different types of bilingual discourse (borrowing, code switching), showing how the Slovene inflectional system in particular is being increasingly generalized, simplified and reduced, and how Slovene word order is gradually beginning to resemble that of English. In the case of Slovenia we are witnessing an unprecedented surge in the influence of English on Slovene, especially in the media (both classic and electronic), advertising, science, and the language of the young. This influence will be discussed on a number of levels, such as lexical, syntactic and intercultural, and illustrated by relevant examples.

The article discusses methods of sense disambiguation in monolingual dictionaries and equivalent differentiation in bilingual dictionaries. In current dictionaries, sense disambiguation and equivalent differentiation is presented in the form of specifiers or glosses, collocators or indications of context, (domain) labels, metalinguistic and encyclopaedic information. Each method is presented and illustrated by actual samples of dictionary articles taken from mono and bilingual dictionaries. The last part of the article is devoted to equivalent differentiation in bilingual decoding dictionaries. In bilingual dictionaries, equivalent differentiation is often needed to describe the lack of agreement between the source language (SL) and target language (TL). The article concludes by stating that equivalent differentiation should be written in the native language of the target audience and sense indicators in a monolingual learner’s dictionary should be words that the users are most familiar with.
Potential Effects of Disturbance Types and Environmental Variability on Sagebrush-Steppe Community Dynamics
Authors: Evers Louisa B. , Miller Richard F. , Doescher Paul S.
Published: May 2015

While fire is widely recognized as an important factor shaping sagebrush (Artemisia spp.) ecosystems, little is known about the role other natural events play in these systems. Using a state-and-transition modeling framework in conjunction with the scientific literature and data for climate (temperature, precipitation, and snow), soils (soil surveys and ecological site descriptions), and modern fire occurrence records, we explored how fire and various other natural events might shape sagebrush ecosystems in eastern Oregon, USA, and whether those events could affect fire rotation. Model results suggested other disturbance events were important in shaping all but the most productive sagebrush communities and influenced fire rotation in drier sagebrush communities. Insects and pronghorn browsing may have been as important as fire in shaping sagebrush-steppe landscapes with freezekill and snow mold locally important. Our study also demonstrated the use of climate, soils, ecological site, and fire occurrence data to derive probabilities of several natural events, providing a more objective approach to estimating reference conditions.
Fire Regime, Climate, and Vegetation in the Sierras de Córdoba, Argentina

Wildfires are a primary disturbance in the Sierras de Córdoba, Argentina, with approximately 2 152 000 ha burned between 1993 and 2012. However, little is known about the spatial and temporal patterns of fires and their relationship with climate and vegetation in this area. Such information is of great value for fire risk assessment and the development of strategies for fire management. Our main objective was to analyze fire activity in four sierran ranges, assessing which weather and climate conditions were mostly related to fire activity, and which land cover types were mostly burned. We used a fire database of mid-high spatial resolution and a land cover map derived from Landsat imagery. Fire regimes were different among the different sierran ranges. The Sierras Chicas range was the most affected by fires, with the largest number of fire events, burned area, and fire frequency. Although large fires represented 3 % to 5 % of fire events, they accounted for 60 % to 86 % of total burned area in different sierran ranges. Sierras of lower elevation had a winter seasonality of fires, while sierras of higher elevation had a winter-spring or spring fire seasonality. The number of fire events was positively correlated with preceding periods that were wetter than normal, while the burned area was mainly associated with midterm weather conditions. Fires occurred mainly in grasslands and shrublands, but the area of burned forests was important, too. Our results will be useful to determine the times and conditions in which fire risk is highest, and also to identify where preventive efforts should be focused.
Latitude dependence of long-term geomagnetic activity and its solar wind drivers

Abstract. To validate the usage of global indices in studies of geomagnetic activity, we have examined the latitude dependence of geomagnetic variations in Fennoscandia and Svalbard from 1994 to 2010. Daily standard deviation (SD) values of the horizontal magnetic field have been used as a measure of the ground magnetic disturbance level. We found that the timing of the geomagnetic minimum depends on the latitude region: corresponding to the minimum of sunspot cycle 22 (in 1996), the geomagnetic minimum occurred between the geomagnetic latitudes 57–61° in 1996 and at the latitudes 64–67° in 1997, which are the average auroral oval latitudes. During sunspot cycle 23, all latitude regions experienced the minimum in 2009, a year after the sunspot minimum. These timing differences are due to the latitude dependence of the 10 s daily SD on the different solar wind drivers. In the latitude region of 64–67°, the impact of the high-speed solar wind streams (HSSs) on the geomagnetic activity is the most pronounced compared to the other latitude groups, while in the latitude region of 57–61°, the importance of the coronal mass ejections (CMEs) dominates. The geomagnetic activity maxima during ascending solar cycle phases are typically caused by CME activity and occur especially in the oval and sub-auroral regions. The strongest geomagnetic activity occurs during the descending solar cycle phases due to a mixture of CME and HSS activity. Closer to the solar minimum, less severe geomagnetic activity is driven by HSSs and mainly visible in the poleward part of the auroral region. According to our study, however, the timing of the geomagnetic activity minima (and maxima) in different latitude bands is different, due to the relative importance of different solar wind drivers at different latitudes.
MOOCS – A FORCE TO BE RECKONED WITH OR A TEMPORARY PHENOMENON
Authors: Koenig G.
Published: May 2015

Abstract. The digital revolution has dramatically changed our everyday life. Using the Internet has evolved into a key technology that became an indispensable information source. The expansion of Internet usage beyond mere information storage to a learning and communication tool sets new standards for the development of educational concepts. Digital textbooks, multimedia tutorials, elearning offers using learning management systems and massive open online courses (MOOCs) demonstrate the development phases of new strategies for knowledge transfer. Initially starting in the USA MOOC platforms like Udacity, Coursera or edX had gained an enormous media attention caused by the huge number of participants. Initially this new teaching method was welcomed euphorically; the didactic preparation of courses is however viewed with scepticism, particularly in Europe. This paper will review the status of MOOCs, with a particular emphasis on Photogrammetry, Remote Sensing, and Geomatics. A selection of these 'Geo-MOOCs' will be presented. The consideration of these free online learning resources will include a commentary on quality and perceived effectiveness. Finally it will be outlined if MOOCs are reasonable and promising in our fields.

In this article, we determine certain conditions under which the partial sums involving thecomplex Baskakov-Stancu operators of analytic univalent functions of bounded turning are also of boundedturning. Moreover, we consider some geometric properties such as starlikeness and convexity for these partialsums. The lower bound of the partial sums of univalent functions is computed using the lower bound of thecomplex Baskakov-Stancu operators of analytic functions

Quasirecognition by prime graph of $C_{n}(4) $, where $ n\geq17 $ is odd
Authors: Mosavi Somayeh , Ahanjideh Neda
Published: May 2015

Let $G$ be a finite group and let $\Gamma(G) $ be the prime graph of $ G$. We assume that $ n\geq 17$ is an odd number. In this paper, we show that if $ \Gamma(G) = \Gamma(C_{n}(4))$, then $ G$ has a unique non-abelian composition factor isomorphic to $C_{n}(4)$. As consequences of our result, $C_{n}(4)$ is quasirecognizable by its spectrum and by prime graph.

Published: May 2015

A mathematical model is proposed and analyzed for the understanding of growth pattern of mosquito vector looking into its life cycle. The objective of this study is to develop a mathematical model that can fit to the real data provided by DRDE scientist for different month at different stations so that the seasonal variation in population density of mosquitoes can be reported accurately to the estimated data obtained by the proposed mathematical model.  The aquatic class $(L)$ and adult stage is divided in two class, indoor population $(I)$ and outdoor population $(O)$. Here we estimated different parameters of our proposed continuous model and numerically simulation is done to compare the estimated data with the original data.

Published: May 2015

Let R be a ∗-prime ring with involution ∗ and center Z(R). An additive mapping F:R→R is called a semiderivation if there exists a function g:R→R such that (i) F(xy)=F(x)g(y)+xF(y)=F(x)y+g(x)F(y) and (ii) F(g(x))=g(F(x)) hold for all x,y∈R. In the present paper, some well known results concerning derivations of prime rings are extended to semiderivations of ∗-prime rings.
