Change detection (CD) between a pair of images is a popular problem in remote sensing. Despite a large amount of data is acquired every day by remote sensing satellites, standard CD methods usually consider only the two target images between which we desire to detect changes. The aim of this work is to present a novel framework in which the bi-temporal CD is redefined by evaluating the consistency...
The potential of Split-Band processing to determine the absolute phase of an interferometric pair of SAR images has been demonstrated in previous studies. In this work we propose a new approach based on the joint use of Split-Band Interferometry and SAR Interferometry for the phase leveling of disconnected regions of an unwrapped interferogram. In this paper a new selector of frequency-persistent...
Need for end-to-end secure voice communication under the cyber security threats are increasing day by day. This paper describes a method of establishing secure VOIP system in which the voice encoded with the SYMPES [1] coding technique and encryption set with an open standard encryption algorithm. Voice can be transmitted from point to point within a secure IP network. A Graphic Processing Unit (GPU)...
With the omnipresence of video playback on handheld devices, better interface design for fast access to mobile video content becomes essential. We present two experiments investigating optimum interaction with storyboard-based designs for mobile video browsing. Concretely, we evaluate maximum speeds at which users can process visual information; an important characteristic when quickly skimming storyboards...
Stemming is a technique that transforms morphologically similar terms into a unique term without doing a complete morphological analysis. Stemming is used as a preprocessing step in many Natural Language Processing (NLP) applications like Information retrieval (IR), Machine Translation, Parsing, Summarization, etc. The present work explores the application of stemming to the task of information retrieval...
The multiple hypothesis tracker (MHT) has historically been considered a gold standard for multi-target tracking. In this paper we show that the key formula for hypothesis probabilities in Reid's MHT can be derived from the modern theory of finite set statistics (FISST) insofar as appropriate assumptions (Poisson models for clutter and undetected targets, no target-death, linear-Gaussian Markov target...
The evaluation of recommender system is often biased towards accuracy, which is hard to balance all participants' interests. In this paper, a novel recommendation strategy using expanded neighbor collaborative filtering (ECF) is presented. Different from the standard collaborative filtering (CF), this recommendation strategy takes into account the second-order neighbors, which are expected to contribute...
We consider the integrated fractional Brownian motion with Hurst index 0 < H < 1. The main aim consists in studying its links with the quasi-helix with approximately stationary increments class of centered Gaussian processes. More precisely, we compute some well-chosen quantities which depend on the moments of the integrated fractional Brownian motion. Firstly, we check if one can obtain appropriate...
Meeting the communication needs of individuals requires an understanding of the contexts where they use materials. Addressing this objective requires an understanding of the complex contexts in which patients use such materials. A modified version of script theory can address such situations.
This paper questions the sizing standardization of small scale energy storage systems in a context of high penetration of renewable energies and non-deterministic load within the power grid. The future electrical grid is more precarious than the classic one by many reasons, inter alia, abrupt meteorological variations are hard to predict. Therefore, the geographic expansion beside high penetration...
Introduction. The priority directions in pediatric otorhinolaryngology are development of diagnostic criteria in chronic tonsillitis in children and argumentation of complex conservative therapy tactics to preserve palatine tonsils as important organs in local and general immunity.
Virtual Reality applications for integrated cognitive and motor stroke rehabilitation show promise for providing more comprehensive rehabilitation programs. However, we are still missing evidence on its impact in comparison with standard rehabilitation, particularly in patients with cognitive impairment. Additionally, little is known on how specific stimuli in the virtual environment affect task performance...
This paper investigates the M&A performance of coal listed companies in our country that experienced M&A from the years 2008 to 2012. The factor analysis method and comparative analysis method are employed and further the multiple regression analysis is used to identify the important factors for short-term M&A performance. The results show that the performance of coal companies in our...
We extend the self-organizing mapping algorithm to the problem of visualizing data on Grassmann manifolds. In this setting, a collection of k points in n-dimensions is represented by a k-dimensional subspace, e.g., via the singular value or QR-decompositions. Data assembled in this way is challenging to visualize given abstract points on the Grassmannian do not reside in Euclidean space. The extension...
This paper investigates the influence of internal control on executive pay-performance sensitivity in public welfare SOE and commercial SOE in China by empirical study. Finally, we find that the implementation of internal control can not improve executive pay-performance sensitivity in all kinds of SOE, which means the reform of state-owned enterprises in China can not be the same mode. We need to...
Light fingertip contact with an earth-fixed referent decreases body sway. In a previous study Johannsen et al. (2014) demonstrated longer return-to-baseline of body sway for intermittent contacts of more than 2 seconds duration. This indicates that sway reduction with light tactile contact involves postural control strategies independent of the availability of tactile feedback and may depend on the...
Power quality related to DC microgrids is still on virgin grounds of research. However, it may play an important role both in the design stage and on the DC microgrid control scheme to be adopted. Currently there is no comprehensive, quantitative and qualitative analysis on which of the power quality features are the most stringent constraints to be taken into account. This work is an attempt of defining...
This contribution introduces an evolutionary algorithm (EA) for continuous optimization in ℝn. The algorithm generates new individuals by the standard nonelitist truncation selection and the differential mutation to generate new individuals. The differential mutation is enriched by adding a random vector in the direction of the shift of population midpoint. Difference vectors are generated with the...
Affordable and reliable supply chain visibility is becoming increasingly important as the complexity of the network underlying supply chains is becoming orders of magnitudeshigher compared to a decade ago. Moreover, this increase in complexity is starting to reflect on the cost of goods and their availability to the consumers. This paper addresses two key issues in the distribution phase of the supply...
In the recent years, the rapid increase of industrial pollution, scientific evaluation of air quality is an important research topic. This is the Bias network applied to the city air quality evaluation of air quality characteristics, establish a directed acyclic graph (DAG), and the air quality data of Shanghai for training and validation, the experimental results coincide with the actual situation,...
