PANEL COINTEGRATION ANALYSIS OF INTERNATIONAL TOURISM DEMAND: SAMPLE OF ANTALYA

This paper aimed to find the short-run and long-run relationships between international tourism demand to Antalya with economic variables such as income (GDP) and tourism price. Seasonally adjusted quarterly tourist arrivals data were used for 36 countries over the period 1996Q1 – 2014Q4. Firstly, panel unit root test such as Levin, Lin and Chu (LLC) (2002) panel unit root test, Maddala and Wu (1999) and Choi (2001) panel unit root test were used. Then the panel cointegration test based on Kao (1999) panel cointegration test and Pedroni (1999) panel cointegration test were used to test cointegration relationship among the variables in the long-run. Also we used a new technique of estimating dynamic heterogeneous panels, which is developed by Pesaran, Shin and Smith (1999), for the international tourism demand model. Pooled Mean Group (PMG) estimator is particularly convenient for panels with large T and N. The PMG estimator allows the intercepts, short-run coefficients and error variances to differ across groups while constrains the long run coefficients to be identical. The long-run results of this study show that growth in income (GDP) of the countries concerned has positive effect on international visitor arrivals to Antalya. However, tourism price was not found as determinants of international tourism demand in Antalya since the tourism price parameter is not statistically significant. Also error correction coefficient is negative and statistically significant. This findings show an existence of long-run relationship
Comparison of multilevel inverters for static VAr compensation

Inverter-based static VAr compensators (SVCs) can benefit from the use of a multilevel invertor structure which allows the elimination of the step-up transformer. The inherent high quality of the multistep waveform allows operation without PWM, thus high switching losses are avoided. This paper discusses the issues affecting the application of multilevel invertor structures as reactive power compensators and compares the device MVA and reactive component MVA requirements of two topologies that have been presented in prior literature. The modulation strategy strongly affects the voltage balancing in the DC bus capacitors as well as their ripple current rating and capacitance value. <<ETX>>
Using Topological Data Analysis to Infer the Quality in Point Cloud-based 3D Printed Objects

Introduction: 3D printing of parts is gaining incredible popularity in manufacturing. However, assessing the quality of models before they are printed remains a challenging problem, particularly when you consider point cloud based models [3], such as those that come from 3D scanners. This paper introduces an approach to quality assessment, which uses techniques from the eld of Topological Data Analysis (TDA) to compute a topological abstraction of the eventual printed model. This abstraction enables investigating certain properties of the model, with respect to print quality, and identify potential anomalies that may appear in the nal product.
Combinatory logic

the equations derivable from the axioms of the theory. When this two-step algebraization has been carried out it is possible to reduce problems of validity in a first-order language to questions about derivability of equalities from equations. The above process is applied to obtain three algebraic languages and theories. The first language L„ is developed in Chapters 2 and 3. It is based on an extension of j <p j to an operation on sets of finite sequences of arbitrary finite length (called \<a-operations). The symbols for L„ are the same as for o>-dimensional cylindric algebras with the addition of symbols for the projection operation and its natural right inverse. The function symbols of L„ are interpreted as |w-operations. Axioms for a sound equational theory in L,, are given in Chapter 4, which is devoted to deriving consequences of these axioms. A Henkin-style completeness proof for the equalities of this theory is the content of Chapter 5. The second and third algebraic languages and theories are developed in Chapters 7 to 10. They are both based on an extension of j ip j to an operation on sets of sequences of length a>. The two languages are determined by different generating sets for the same set of 10 -operations. The second algebraic language is syntactically the same as L„; it differs only in that its function symbols are interpreted as to -operations. The third language is related to the language of o>-dimensional polyadic algebras with generalized diagonal elements. It contains operators (S„) and (T„) where (S«) is a substitution operation with conjugate (T„) for each a in a certain semigroup of transformations on <o. Generalizations of the third language and the corresponding equational theory are obtained by considering arbitrary semigroups of transformations. The third algebraization of logic is discussed in this more general context in Chapters 9 to 11. Most of the book pursues completeness results. Chapter 11, however, deals with some semigroups of transformations for which the corresponding theory is not complete for all equalities. Much of this chapter is based on work by Ralph McKenzie.

A new Effective Approach for Categorizing Web Documents

Categorization of Web documents poses a new challenge for automatic classification methods. In this paper, we present the megadocument approach for categorization. For each category, all corresponding document texts from the training sample are concatenated to a megadocument, which is indexed using standard methods. In order to classify a new document, the most similar megadocument determines the category to be assigned. Our evaluations show that for Web collections, the megadocument method clearly outperformes other classification methods. In contrast, for the Reuters collection, we only achieve mediocre results. Thus, our method seems to be well suited for heterogeneous document collections.
Analysis , Mathematical Model and Simulation of Selected Components of Advanced Technological Solutions of HVDC Architecture of Modern Aircraft Compatible with the Concept of MEA / AEA

Conventional voltage of (28V DC, 115V/ 400 Hz AC) in traditional electro-energy power system EPS (Electric Power System), used for the "classic" aircraft (civilian and military) do not meet the requirements of advanced on-board autonomous power systems ASE (Autonomous Electric Power Systems) in the context of a modern system of EPS and a power electronic power system PES (Power Electronics Systems). It is dictated first of all by the fact that the concept of a more electric aircraft obliges manufacturers to implement in modern aerospace advanced solutions, among others in the field of high voltage power HVDC (High Voltage Direct Current). The subject, and also the purpose of this paper is to introduce the theme of aviation in terms of power HVDC, making its analysis by creating a mathematical model and simulation in software environment of Matlab/ Simulink selected components of the system ASE (EPS, PES) in the context of architecture HVDC in the range of high voltage DC 540V DC (±270V DC), and 350V DC. In the final part of this paper we present the results obtained on the basis of simulations and conclusions in the field of innovative architecture HVDC power in line with the trend of more electric aircraft (MEA/ AEA).

Physical Activity in US Youth : Impact of Race / Ethnicity , Age , Gender , & Weight Status

Purpose—To describe physical activity (PA) levels by race/ethnicity, age, gender, and weight status in a representative sample of U.S. youth. Methods—Cross-sectional data from the 2003–4 and 2005–6 National Health and Nutrition Examination Survey (NHANES) were combined and analyzed. Youth ages 6 to 19 with at least 4 10-hour days of PA measured by accelerometry were included (N=3,106). Outcomes included mean counts per minute and minutes spent in moderate to vigorous PA (MVPA). Results—6 to 11 year olds spent more time (88 min/day) in MVPA than 12 to 15 (33 min/day) and 16–19 (26 min/day) year olds (p<.001 for both). Females spent fewer min/day in MVPA than males (p<.001). Overall, obese youth spent 16 fewer min/day in MVPA than normal weight youth. However, non-Hispanic White (NHW) males spent 3–4 fewer min/day in vigorous PA than Mexican American (MA) (p=.004) and non-Hispanic Black (NHB) (p<.001) males but had lower obesity rates; and obese 12 to 15 year old MA recorded similar minutes in MVPA per day as normal weight MA (p>.050). There was a significant 3-way age-BMI-race/ethnicity interaction for mean min/day in MVPA (p<.001). Adjustment for total energy intake did not qualitatively alter these results. Conclusion—Females and older youth were the least active groups. Obese youth were generally less active, but this did not hold uniformly across race/ethnic groups. Cultural or biological factors could moderate the association between PA and obesity in youth.
Use on Alien Plant Composition along a Riparian Corridor in the Cape Floristic Region , South Africa

Riparian zones are important for the many ecosystem services they supply. In settled areas, the vegetation of such zones is shaped by human land use; this often creates conditions under which alien plant species thrive. Alien plants have been shown to induce large-scale changes in riparian habitats, and they pose a major threat to the continued provision of key ecosystem services. Direct gradient analysis was used to assess the effects of land use on the composition of vegetation along a riparian river corridor in the highly transformed landscape surrounding Stellenbosch in South Africa’s Western Cape Province. Vegetation plots were sampled along the entire length of the river from headwaters to estuary (ca. 40 km). Plant community composition was analyzed in relation to land-use data collected in the field, and additional land-use variables computed from digital land-cover data. Patterns of plant species composition were found to be directly related to land use, with measures of cover, richness, and diversity differing significantly between land-use types. Several native species were found to remain competitive in areas with high abundance and diversity of invasive alien plants, suggesting that they will be valuable focal species for future restoration attempts. Due to the level of human-mediated change in many areas of the riparian zone, restoration to historic conditions over most of the river is not considered feasible. These areas should be recognized as examples of novel ecosystems, and management efforts should focus on restoring or creating desirable ecosystem functions, rather than on achieving assemblages comprising only native species. Key-words: biological invasions; landscape change; ecosystem services; ecosystem transformation; restoration; novel ecosystems
Radiobiological response of U 251 MG , CHOK 1 and V 79 cell lines to accelerator-based boron neutron capture therapy

In the current article, we provide in vitro efficacy evaluation of a unique accelerator-based neutron source, constructed at the Budker Institute of Nuclear Physics (Novosibirsk, Russian Federation), for boron neutron capture therapy (BNCT), which is particularly effective in the case of invasive cancers. U251MG, CHO-K1 and V79 cells were incubated and irradiated in various concentrations of boric acid with epithermal neutrons for 2–3 h in a plexiglass phantom, using 2.0 MeV proton energy and 1.5–3.0 mA proton current, resulting in a neutron fluence of 2.16 × 10 cm. The survival curves of cells loaded with boron were normalized to those irradiated without boron (to exclude the influence of the fast neutron and gamma dose components) and fit to the linear– quadratic (LQ) model. Colony formation assays showed the following cell survival rates (means ± SDs): CHOK1: 0.348 ± 0.069 (10 ppm), 0.058 ± 0.017 (20 ppm), 0.018 ± 0.005 (40 ppm); V79: 0.476 ± 0.160 (10 ppm), 0.346 ± 0.053 (20 ppm), 0.078 ± 0.015 (40 ppm); and U251MG: 0.311 ± 0.061 (10 ppm), 0.131 ± 0.022 (20 ppm), 0.020 ± 0.010 (40 ppm). The difference between treated cells and controls was significant in all cases (P < 0.01) and confirmed that the neutron source and irradiation regimen were sufficient for control over cell colony formation. We believe our study will serve as a model for ongoing in vitro experiments on neutron capture therapy to advance in this area for further development of accelerator-based BNCT into the clinical phase.
DESTINATION MARKETING AND REBRANDING TOURISM IMAGES OF IPOH CITY, MALAYSIA

The study of destination image is a relatively recent addition to the field of tourism research. Several studies have illustrated that destination images do, indeed, influence tourist behaviour. In essence, the research suggests that those destinations with strong, positive images are more likely to be considered and chosen in the travel decision process. As a result, destination image has an important role in the various models of travel decision making developed to date. As more and more areas are developed for tourism, the destination choices available to consumers continue to expand. One of the most significant marketing challenges arising from this situation is the need for an effective destination positioning strategy. The research attempts to demonstrate that successful rebranding of destination images of Ipoh city in Malaysia will be valuable in understanding the destination selection process of the tourist’s markets and the relationship between destination image and preference or visitation intentions. In this manner, the various strengths, weaknesses, accuracies and inaccuracies of the existing destination images could be more effectively addressed in the design of the promotional strategies, locally and abroad. This research employs a survey among tourists and visitors to Ipoh about their perceptions of Ipoh’s destination images, destination attributes and revisit intentions. The research recommendations include understanding the market characteristics and selecting the tools correctly when designing the promotional mix; building brand loyalty through relationship marketing as visitors/tourists had an overall very good assessment of their trips to Ipoh; positioning and differentiating Ipoh from its competitors by bundling competitive advantages and offering more benefits for similar products; and creating an international icon that will be the must-see attraction and instantly recognizable, nationally and globally. Keywords— Destination Marketing, Tourism Images.
On the use of the concept of quantum-unstable states in General Relativity : the blackhole radiation as a barrier phenomenon

The physics of black holes, and particularly the study of Hawking’s radiation, is a sensitive subject in several fields, from General Relativity to Cosmology. Its basic explanation involves the creation and annihilation of particle-antiparticle pairs at the boundary. Here we develop a different approach to the problem based on the notion of unstable quantum states. We derive the expressions from general relativity and show that the black-hole radiation may be understood as a quantum mechanical emission from a barrier.
The ‘ decision-making ’ on the trade of ' Cultural Artefacts ' , applying the role of tourism to measure the economic perspective

Tourism continues to flow into Africa and along with this flow of tourism, is the flow of tourist spending. Much of the spending is used to purchase goods and souvenirs that are unique to the region from which they are bought. While tourism spending greatly contributes towards the growth and development of these regions, there is also the added benefit associated with the trade of 'Cultural Artefacts'. Each year, thousands of historically significant artefacts exchange hands across the world. What makes these artefacts so significant is that they contain within them an element of ‘cultural value’. This ‘cultural value’ is specific to the information, subjective norm and institutional importance relevant to religious, social and geographic location. The flow of Art from these regions is highly correlated with the flow of tourism, and tourism facilitates the link between local and international art markets. Yet the trade of 'Cultural Artefacts' which are rich in 'cultural significance' operate on a different level to that of ‘works of art’. This paper looks at the way in which the value of items of 'cultural significance' are considered within an economic context and proposes a methodology, to determine the role of value, within an historical cultural framework.
Andreas Lind

The Choice Blindness-methodology has introduced a novel way of investigating the properties of confabulation in introspective verbal reports. Johansson et al (2005a) showed participants 15 picture-pairs of female faces and asked them to, for each pair, choose the one they found most attractive. By asking participants to motivate their choices and by, unknown to the participants, manipulating the outcome of some of these choices, the experimenters have shown that it comes quite naturally to a normal person to motivate a choice he or she manifestly did not intend to make. This thesis aims at investigating such manipulated choice-reports by comparing them with the non-manipulated choice-reports from the same experiment. It is shown that while there are differences between manipulated and non-manipulated choice-reports, these are few and difficult to interpret.
Myoelectric signal classification using a finite impulse response neural network

Recent work by Hudgins (1993) has proposed a neural network-based approach to classifying the myoelectric signal (MES) elicited at the onset of movement of the upper limb. A standard feedforward artificial network was trained (using the backpropagation algorithm) to discriminate amongst four classes of upper-limb movements from the MES, acquired from the biceps and triceps muscles. The approach has demonstrated a powerful means of classifying limb function intent from the MES during natural muscular contraction, but the static nature of the network architecture fails to fully characterize the dynamic structure inherent in the MES. It has been demonstrated previously that a finite-impulse response (FIR) network has the ability to incorporate the temporal structure of a signal, representing the relationships between events in time and providing translation invariance of the relevant feature set. The application of this network architecture to limb function discrimination from the MES is described here.

A New Effective Criterion to Select Sentences in Extractive Text Summarization

This paper introduces a new criterion to get better performance in selecting the most important sentences of text for extractive text summarization. There are two kinds of criteria to find the most relevant sentences of text: statistical criteria and semantic relations between text sentences. The proposed technique is a statistical criterion. The idea behind our approach is to consider the position of sentence words relative to words in the sentence occurring in title and keywords. We evaluate this criterion in combination with other statistical criteria. The results show that using this criterion in selecting the most important sentences of text has good results
A Novel Transient Current Limiter Based on Three-Phase Thyristor Bridge for Y-yg Transformers

The transformer in flux current may be a transient current that happens in electrical devices has been charged. This current depends on completely different parameters probably the voltage magnitude, the switching on angle the permanent flux, the core physical phemeon characteristics, the primary circuit resistance, etc. To beat the issues arising owing to transients, these are required to be suppressed.In this paper, an easy and economical techniquie is conferred to limit the transient current of the Y-yg transformers. One amongst the most benefit of this technique is it doesn’t would like any negative feedback circuit or activity unit. The tactic relies on a three-phase thyristors bridge single LC reactor with the individual phases of electrical device. Since the amount of thyristors is reduced, the voltage ripple, electrical losses and therefore the malfunction likelihood due to device failure is reduced significantly. The projected technique has been simulated by MATLAB simulation. It’s shown that the projected style is a lot of economical for the transient current limitation of Y-yg transformers.
