This paper examines empirically the tourism impact on the long-run economic growth of Greece by using the causality analysis among real gross domestic product, real effective exchange rate and international tourism earnings. A multivariate autoregressive VAR model is applied for the examined period 1960:Ι – 2000:IV. The results of cointegration analysis suggested that there is one cointegrated ...

Time-of-Flight (ToF) cameras, a technology which has developed rapidly in recent years, are 3D imaging sensors providing a depth image as well as an amplitude image with a high frame rate. As a ToF camera is limited by the imaging conditions and external environment, its captured data are always subject to certain errors. This paper analyzes the influence of typical external distractions includ...

Robustness of phoneme recognition to additive noise is investigated for PLP and acoustic waveform representations of speech using support vector machines (SVMs) combined via error-correcting code methods. While recognition in the PLP domain attains superb accuracy on clean data, it is significantly affected by mismatch between training and testing noise levels. The classification in the high-di...

Tumor oxygen status is a reliable prognostic marker that impacts malignant progression and outcome of tumor therapy. However, tumor oxygenation is heterogeneous and cannot be sufficiently described by a single parameter. It is influenced by several factors including microvessel density (MVD), blood flow (BF), blood volume (BV), blood oxygen saturation, tissue pO(2), oxygen consumption rate, and...

This work is concerned with improving the robustness of phoneme classification to additive noise with hybrid features using support vector machines (SVMs). In particular, the cepstral features are combined with local energy features of acoustic waveform segments to form a hybrid representation. The local energy features are taken into account separately in the SVM kernel, and a simple subtracti...

In this paper, a reliable information hiding scheme based on support vector machine and error correcting codes is proposed. To extract the hidden information bits from a possibly tampered watermarked image with a lower error probability, information hiding is modeled as a digital communication problem, and both the good generalization ability of support vector machine and the error correction c...

This report is based on the article [1] by Koetter and Kschischang. The authors introduced a novel approach for constructing codes by selecting a subset of a powerset of a vector space. With the code construction, they also defined an operator channel for code transmission. The codewords are vector subspaces. The data is transmitted by using one of the bases of such a subspace. The properties o...

in this paper, nonlinear adjustments and price transmission mechanism between the two levels of wholesale and retail for the egg market has been examined under the threshold vector error correction model (tvecm) framework using hansen and seo (2002)’s two-regimes). the unit root test showed that both wholesale and retail egg price series were integrated of order one . the johansen co-integratio...

In this paper bi-annual time series data on unemployment rates (from the Labour Force Survey) are expanded to quarterly rates and linked to quarterly unemployment rates (from the Quarterly Labour Force Survey). The resultant linked series and the consumer price index (CPI) series are examined using Johansen’s cointegration approach and vector error correction modeling. The study finds that both...

In area efficient low error compensation multiplier design is using fixed width RPR (Reduced Precision Redundancy). We propose a new method called fixed width RPR for DSP applications. This fixed width multiplier is placed in ANT architecture to meet high speed, low power consumption and area efficiency. The fixed RPR is designed with compensation circuit for minimizing the occurrence of error....
