Over the last decade, there has been a gradual increase in the number of people with mobility and speech impairments who require novel communication devices. Most of the recent works focus on the Latin script; there is a lack of appropriate assistive devices for scripts that are specific to a country. In this paper, we propose a novel multimodal Hindi language virtual keyboard based on a menu selection...
This paper presents a semi-incremental recognition method for online handwritten mathematical expressions (MEs). The method reduces the waiting time after an ME is written until the result of recognition is output. Our method has two main processes, one is to process the latest stroke, the other is to find and correct wrong recognitions in the strokes up to the latest stroke. In the first process,...
Since Cyber Physical Systems (CPS) are widely used inmany safety-critical domains these days, critical propertiessuch as robustness and resilience are required for such systems. To increase the robustness and the resilience of CPS, various sensor fusion techniques have been studied [1], [2],[3], [4]. These fusion techniques are based on certain sensormodels, which broadly fall into two categories:...
In the real-word matching, deformation, outliers and other emerging variations are inseparable conditions which make matching increasingly difficult. One way to solve this challenging problem is raising an effective graph matching method which is flexible to non-rigid objects. As a good structure representation, graph can nicely describe objects with meaningful information. Meanwhile, feature pooling...
Infographic is a type of information visualization that uses graphic design to enhance human ability to identify patterns and trends. It is popularly used to support spread of information. Yet, there are few studies that investigate how infographics affect learning and how individual factors, such as learning styles and enjoyment of the information affect infographics perception. In this sense, this...
This paper proposes a robust optimization (RO) model for bidirectional dispatch coordination of large-scale plugin electric vehicles (PEVs) in a power grid in which the PEVs are aggregated to manage. The PEV aggregators are considered as a type of dispatchable demand response and energy storage resource with stochastic behaviors, and can supply load or provide ancillary services such as regulation...
In recent years parallel computing has been widely employed for both science research and commercial applications. For parallel systems such as many-core or computer clusters, it is inevitable to have one or more computing node failures due to random errors or injected attacks. Usually a diagnosis mechanism is able to locate several defective nodes through a number of tests and the analysis of those...
The robustness of networks suffering site or link attacks is a topic of great interest because it is an important issue affecting many real-world networks. The robustness of complex networks under attack is dependent upon the structure of the underlying network and the nature of the attack. However, random attack and hub-targeted attack do not adequately describe many real-world scenarios in which...
Corresponding points matching is a one of the primitive problems in computer vision and image processing which is used in a vast verity of applications such as stereo vision, image registration, object detection, motion analysis and image retrieval. In this paper, we present a new framework to improve the performance of interest points matching using not only the feature descriptors of keypoints,...
In this paper, we propose a space character based reversible high capacity text steganography scheme which embeds the secret data into a Microsoft word document. The scheme hides the secret data bits into the white spaces by changing their font type and style. Since the white spaces are invisible characters, the changes made in their style as well as in their font type do not raise suspicion. Thus,...
In this paper, fractional order proportional integral derivative controller (FOPID) has been designed to get a desired performance form a separately excited Direct Current (DC) motor fed by a buck converter. The robustness of the DC motor speed control is increased using this FOPID controller due to the effect of increased iso-damping response. This increased iso-damping occurs due to the addition...
Proportional Integral Derivative (PID)-type controller are the most commonly used control algorithm in industry due to their practicality. Two design techniques are presented for tuning the parameters of the controller, Zeigler-Nichols and the Åström-Hägglund method based on certain design specifications. In order to achieve better performances, different combinations of parameters from the two techniques...
Digital audio watermarking aims to embed digital information in the form of multimedia files such as text, image or audio into an original audio signal. The main requirement of audio watermarking is to prove ownership as well as copyright protection. This paper presents efficient audio watermarking based on Wavelet transform. The L level Haar Wavelet transform is performed on the audio signal and...
In the cooperative data exchange problem, a set of clients share a lossless broadcast channel. Each client initially has a subset of packets in the ground set X, and wishes to learn all packets in X. The clients exchange their packets with each other by broadcasting coded or uncoded packets. In this paper, we consider a generalization of this problem for the settings in which an unknown (but of a...
In this paper, operator-based robust perfect control for nonlinear semiconductor refrigeration device with uncertainties is considered. For the research about the properties of the semiconductor refrigeration, an aluminum plate with Peltier device is very representative. So, the perfect tracking control performance is studied by using this device. The robust right coprime factorization approach is...
The complexity associated with Urdu fonts regarding OCR in newspapers is being dealt with active research. When creating an Urdu OCR you are limited to a certain font size i.e. if working with a font size of 12, you will have to create a database covering all characters/words of font size 12. In order to work with another font size of same Urdu font you'll have to cover all the characters/words of...
Advances in mobile health (mHealth) has been notable in the last few years, but so has the problems associated with the development, implementation and sustained use of mHealth systems. After implementation, various difficulties arise contributing to being considered a failure. The purpose of the study is to create a model by which e-Health systems can be evaluated in order to ensure development for...
The Christmas and new year 2016 are coming, in order to stimulate the future development, explore novel applications, and exchange ideas for developing robust solutions, the 12th International Computer Conference on Wavelet Active Media Technology and Information Processing 2015 (ICCWAMTIP 2015) is held at University of Electronic Science and Technology of China (UESTC) in Chengdu on December 2015...
This paper treats with the issue of disturbances, noises, uncertainties and sensor faults estimation for uncertain nonlinear systems whose nonlinearity satisfies the Lipschitz condition. The general idea of this approach is to establish an augmented model by supposing the sensor faults as an auxiliary state. In order to ensure the robustness of the proposed observer and guaranteed the convergence...
This paper deals with the problem of state estimation for perturbed output nonlinear systems. A multiple models approach is used to describe such class of systems. Then a structure of Lyapunov based sliding mode multiple observer is presented. The stability proof of the observer is ensured by a suitable choice of estimation gains which are solutions of a set Linear Matrix Inequalities(LMI). The simulation...
