Fog computing has been widely deployed in intelligent production lines to provide real-time computing services for terminal devices to alleviate the transmission problem between cloud and terminal. Nevertheless, when there are many services provided in a single fog node, how to choose an optimal data processing path is a challenge to minimize optimization latency and power consumption while ensuring the reliable transmission of data with different priorities. To address the problems as mentioned above in this paper, we first propose a joint evaluation model of time latency and power consumption based on task priority. then, we formulate a fog computing adaptive scheduling algorithm (FCAS) based on dynamic programming to obtain the optimal path for processing data with different priorities at fog nodes. Experimental results illustrate that our proposed evaluation model and algorithm have lower power consumption, high efficiency, and higher reliability. (C) 2021the Authors. Published by Elsevier B.V.

this work presents a surface wave antenna metallic pattern prediction from electric field in near-field by applying Bidirectional Gated Recurrent Unit neural network prediction model. the metallic pattern of the proposed antenna has been predicted by using Bi-GRU neural network model with prediction accuracy 100% at 34.5G1Iz. Different uniform mark-space-ratios (MSR) of the metallic pattern do not affect the metallic pattern prediction accuracy.

We explore the problem of learning and predicting popularity of articles from online news media. the only available information we exploit is the textual content of the articles and the information whether they became popular by users clicking on them or not. First we show that this problem cannot be solved satisfactorily in a naive way by modelling it as a binary classification problem. Next, we cast this problem as a ranking task of pairs of popular and non-popular articles and show that this approach can reach accuracy of up to 76%. Finally we show that prediction performance can improve if more content-based features are used. For all experiments, Support Vector Machines approaches are used.

We present a new video character recognition method based on hierarchical classification. In the first step, we propose a method for character segmentation of the text line detected by the text detection method. the segmentation algorithm uses dynamic programming to find least-cost paths in the gray domain to identify the spaces between characters. For the segmented characters, we get a Canny edge image as input for the character recognition step. We introduce hierarchical classification based on voting criteria with structural features to classify 62 character classes into different smaller classes. We divide the perimeter of a character into 8 segments according to 8 directions at the centroid. then the shape of each segment is studied to recognize the characters based on distances between the centroid and end points, and distances between the midpoint and end points. Our experiments on 1462 characters of upper case, lower case and numerals shows that 10% samples per class for training is enough to obtain 94.5% recognition accuracy. the dataset is chosen from TRECVID database of 2005 and 2006.

User Authentication module plays a crucial role in a software system. this module must be very well defined by Cyber Security Experts. It takes much versatility according to changes in environment as well as technology. User authentication may be provided in several ways like user credentials, biological identification, One Time Password and many more. It is difficult and complex to manage future requirement & day to day changes in authentication module. the framework is one of the ways to provide the solution to the problem. there are many tread-offs to design the framework. this paper focuses on software design pattern based framework for authentication module. Using this design pattern based login framework, developers can easily manage future requirement. It provides extensibility and flexibility to applications.

Kirigami is a Japanese art of paper cutting. It is used to obtain three-dimensional shapes via cutting and folding the paper. Origami, however, is based on a series of precise geometric folding without any other changes to the paper. Withthe characteristics of dimensional change and form transformation as well as the advantages of being able to expand and zoom, both Kirigami and Origami have great potential in cross-domain applications. these include biomedical materials, deformable robots, adaptable building cortex, and aerospace science. these applications show different requirements for folding by Kirigami or Origami. this study considered that the knowledge of design must include the operational process used to solve design problems.

Quality of sleep is an important attribute of an elder's health state and its assessment is still a challenge. the sleep pattern is a significant aspect to evaluate the quality of sleep, and how to recognize elder's sleep pattern is an important issue for elder-care community. Withthe pressure sensor matrix to monitor the elder's sleep behavior in bed, this paper presents an unobtrusive sleep postures detection and patternrecognition approaches. Based on the proposed sleep monitoring system, the processing methods of experimental data and the classification algorithms for sleep patternrecognition are also discussed.
