Compared to today's traditional distributed systems, the mobile computing environment is very different in many respects. Limited battery life and high communication prices are bottlenecks in mobile computing, so a new method is urgently needed to resolve such problems. this paper proposed a new framework to meet the demands of future wireless applications. In the framework we propose Asynchronous Access pattern (AAP) and Service Configure File (SCF) supporting disconnection (include voluntarily and involuntarily) operations for mobile clients. AAP allow a mobile user voluntarily disconnect itself from the server to save its battery life and avoid high communication prices. And new wireless applications are easy to be developed/deployed based on SCF in our framework.

An image-based multivariate multiscale entropy (MMSE) method used to measure the size of stacking particles is proposed. the intensive stacking particles with irregular shape and different sizes are collected online and processed by gradient image and one-dimensional coarse graining. Composite delay vectors are formed on row space to eliminate noise between multichannel variables. then, the multivariate multiscale entropy is calculated in order to match the particle sizes. By comparing withthe state-of-the-art methods, the experiment results indicate that the method can obtain the intensive stacking particle size accurately without image segmentation.

Multimodal emotion recognition is a challenging problem in the research fields of human-computer interaction and patternrecognition. How to efficiently find a common sub-space among the heterogeneous multimodal data is still an open problem for audio-video emotion recognition. In this work, we propose an attentive audio-video fusion network in an emotional dialogue system to learn attentive contextual dependency, speaker information, and the interaction of audio-video modalities. We employ pre-trained models, wav2vec, and Distract your Attention Network, to extract high-level audio and video representations, respectively. By using weighted fusion based on a cross-attention module, the cross-modality encoder focuses on the inter-modality relations and selectively captures effective information among the audio-video modality. Specifically, bidirectional gated recurrent unit models capture long-term contextual information, explore speaker influence, and learn intra- and inter-modal interactions of the audio and video modalities in a dynamic manner. We evaluate the approach on the MELD dataset, and the experimental results show that the proposed approach achieves state-of-the-art performance on the dataset.
Support Vector Machine (SVM) is one of the most famous classification techniques in the patternrecognition community. However, due to outliers in the training samples, the SVM tend to be over-trained. this means that...

this study proposes a solution that extends the capabilities of web information systems with single-factor authentication by introducing an additional authentication factor based on biometric face recognition. the proposed solution design and its main operation steps are presented and discussed. the solution utilizes the standard multimedia functionality of popular web browsers and supports available or built-in image capturing devices (photo and web cameras). Robust program algorithms from the open source computer vision library are used for face image processing and analysis. Experimental testing and validation of the algorithms for face localization and recognition are conducted with image sets produced with consideration of reality. Experimental results demonstrate high effectiveness with a success rate of 80% ... 93% for the solution based on the local binary pattern face localization algorithm withthe local binary pattern histogram face recognition algorithm.

the Weather Research and Forecasting (WRF) model is a multi-purpose open source weather model, which is widely used by the wind energy community. However, the state of the art applications that use the WRF model for wind resources do not always meet the sector's needs. the fundamental challenge is the massive quantity of data required for accurate modelling, as well as the expenses associated withthe computing of such massive volumes of data, implying that state-of-the-art approaches are not appropriate. Our work tackles this issue withthe use of a novel orchestration framework relying on cloud computing infrastructure. Cloud computing platforms provide robust infrastructure that allows for the deployment of production-level services as well as extended processing and storage capacity. this paper presents the overall software architecture of a Cloud Orchestration System, enabling the dynamic and flexible cloud deployment of containerized wind resource model chains. Moreover, a set of performance, functional and operational criteria are presented and evaluated, using a real use case of a wind resource model.

We investigate further our intelligent machine vision system for patternrecognition and texture image classification. A database of about 335 texture images of industrial cork tiles is used for this research. the images need to be classified into several classes based on their texture features similarities. In this work, we assume that there is no a priori human vision expert knowledge about the classes. After pre-processing of the data, feature extraction and conducting statistical analysis by applying principal component analysis (PCA) and linear discriminant analysis (LDA), we investigate unsupervised neural network learning. Self-organizing map (SOM) neural networks are trained, tested and validated and the obtained results are discussed and critically compared with research works investigating similar approaches.
