Are stock prices too volatile to be justified by the dividend discount model?
(Elsevier, 2007)This study investigates excess stock price volatility using the variance bound framework of LeRoy and Porter [The present-value relation: tests based on implied variance bounds, Econometrica 49 (1981) 555-574] and of Shiller ... -
Big-data streaming applications scheduling based on staged multi-armed bandits
(Institute of Electrical and Electronics Engineers, 2016)Several techniques have been recently proposed to adapt Big-Data streaming applications to existing many core platforms. Among these techniques, online reinforcement learning methods have been proposed that learn how to ... -
Combined filtering and key-frame reduction of motion capture data with application to 3DTV
(WSCG, 2006-01-02)A new method for combined filtering and key-frame reduction of motion capture data is proposed. Filtering of motion capture data is necessary to eliminate any jitter introduced by a motion capture system. Key-frame reduction, ... -
E-museum: web-based tour and information system for museums
(IEEE, 2006)A web-based system - consisting of data entrance, access and retrieval modules - is constructed for museums. Internet users that visit the e-museum, are able to view the written and visual information belonging to the ... -
Effective early termination techniques for text similarity join operator
(Springer, Berlin, Heidelberg, 2005)Text similarity join operator joins two relations if their join attributes are textually similar to each other, and it has a variety of application domains including integration and querying of data from heterogeneous ... -
Evaluating predictive performance of judgemental extrapolations from simulated currency series
(Elsevier, 1999)Judgemental forecasting of exchange rates is critical for financial decision-making. Detailed investigations of the potential effects of time-series characteristics on judgemental currency forecasts demand the use of ... -
Feedback-labelling synergies in judgmental stock price forecasting
(Elsevier, 2004)Research has suggested that outcome feedback is less effective than other forms of feedback in promoting learning by users of decision support systems. However, if circumstances can be identified where the effectiveness ... -
Financial earthquakes, aftershocks and scaling in emerging stock markets
(Elsevier BV, 2004)This paper provides evidence for scaling laws in emerging stock markets. Estimated parameters using different definitions of volatility show that the empirical scaling law in every stock market is a power law. This power ... -
Human action recognition using distribution of oriented rectangular patches
(Springer, 2007-10)We describe a "bag-of-rectangles" method for representing and recognizing human actions in videos. In this method, each human pose in an action sequence is represented by oriented rectangular patches extracted over the ... -
Improvement of face detection algorithms for news videos
(IEEE, 2005)People are the most important subjects in news videos and for proper retrieval of person images, face detection is a very crucial step. However, face detection and recognition in news videos is a very challenging task due ... -
Intraday dynamics of stock market returns and volatility
(Elsevier BV, 2006)This paper provides new empirical evidence for intraday scaling behavior of stock market returns utilizing a 5 min stock market index (the Dow Jones Industrial Average) from the New York Stock Exchange. It is shown that ... -
Neural networks for improved target differentiation and localization with sonar
(Pergamon Press, 2001)This study investigates the processing of sonar signals using neural networks for robust differentiation of commonly encountered features in indoor robot environments. Differentiation of such features is of interest for ... -
A new directional acoustic lens: V-groove lens
(IEEE, 1993)A new directional acoustic lens is introduced. The geometry is very similar to the line-focus lens except the lens cavity, which is shaped as a groove with flat-bottom V cross section. The slanted planar edges of the groove ... -
Nonrectangular wavelets for multiresolution mesh analysis and compression
(2006)We propose a new Set Partitioning In Hierarchical Trees (SPIHT) based mesh compression framework. The 3D mesh is first transformed to 2D images on a regular grid structure. Then, this image-like representation is wavelet ... -
On reduced order modeling of flexible structures from frequency response data
(IEEE, 2014)In order to identify the dominant flexible modes of a flexible structure with an input/output delay, a numerical method is proposed. The method uses a frequency domain approach (frequency response data) to estimate the ... -
Parsing Turkish using the lexical functional grammar formalism
(Springer/Kluwer Academic Publishers, 1995)This paper describes our work on parsing Turkish using the lexical-functional grammar formalism [11]. This work represents the first effort for wide-coverage syntactic parsing of Turkish. Our implementation is based on ... -
Prediction of protein subcellular localization based on primary sequence data
(2004)Subcellular localization is crucial for determining the functions of proteins. A system called prediction of protein subcellular localization (P2SL) that predicts the subcellular localization of proteins in eukaryotic ... -
Protein folding rates correlate with heterogeneity of folding mechanism
(American Physical Society, 2004)The folding rates of protein were shown to correlate with the degree of heterogeneity in the formation of native contacts. It was shown that both experimental rates and simulated free energy barriers for 2-state proteins ... -
Query expansion with terms selected using lexical cohesion analysis of documents
(Elsevier Ltd, 2007-07)We present new methods of query expansion using terms that form lexical cohesive links between the contexts of distinct query terms in documents (i.e., words surrounding the query terms in text). The link-forming terms ... -
Using data compression for increasing memory system utilization
(Institute of Electrical and Electronics Engineers, 2009-06)The memory system presents one of the critical challenges in embedded system design and optimization. This is mainly due to the ever-increasing code complexity of embedded applications and the exponential increase seen in ...
