A mobile e-business client application may intentionally operate in disconnected mode to reduce the communication cost and the power consumption of mobile devices. We use "data hoarding" to allow business transactions to be processed on the mobile client despite of disconnection, which is implemented by the materialized view. We split the synchronization of a mobile transaction with the server database into 2 steps: intermediate and final synchronization. The intermediate synchronization uses the high cost wireless medium while the final synchronization generally uses the low cost communication medium such as a wired LAN. User can customize the synchronization details including the synchronization type for each data object through the materialized view definition expressed in extended SQL. We present the Transaction-Centric Split Synchronization (TCSS) algorithm and evaluate its performance. It supports the customized synchronization for each object that a transaction accesses. Appropriately selected synchronization details considering the data object's semantics can make it possible to save the power consumption of the mobile device and wireless communication cost. © 2005 IEEE.

Kernel method is a powerful tool in multi-instance learning. However, many typical kernel methods for multi-instance learning ignore the correspondence information of instances between two bags or co-occurrence information, and result in poor performance. Additionally, most current multi-instance kernels unreasonably assign all instances in each bag an equal weight, which neglects the significance of some "key" instances in multi-instance learning. Last but not least, almost all the multi-instance kernels encounter a heavy computation load, which may fail in large datasets. To cope with these shortcomings, we propose a FAst kernel for Multi-instancE leaRning named as FAMER. FAMER constructs a Locally Sensitive Hashing (LSH) based similarity measure for multi-instance framework, and represents each bag as a histogram by embedding instances within the bag into an auxiliary space, which captures the correspondence information between two bags. By designing a bin-dependent weighting scheme, we not only impose different weights on instances according to their discriminative powers, but also exploit co-occurrence relations according to the joint statistics of instances. Without directly computing in a pairwise manner, the time complexity of FAMER is much smaller compared to other typical multi-instance kernels. The experiments demonstrate the effectiveness and efficiency of the proposed method. Copyright © SIAM.

A novel objective quality for image fusion based on structural similarity and visual attention mechanism (VAM) is presented. By giving higher weight to the salient areas in the input images, the quality measure can estimate how much visual meaningful information is preserved in the fused image. The correlation analysis between objective measure and subjective evaluation showed that our measures are more consistent with human subjective evaluation. ©2010 IEEE.

Nonsubsampled contourlet transform (NSCT) can provide flexible multiresolution, anisotropy, and directional expansion for images. Compared with the original contourlet transform, it is shift-invariant and can overcome the pseudogibbs phenomena around singularities. Fuzzy logic is an efficient intelligent method to handle uncertain information. In this paper, a novel image fusion algorithm is proposed based on the NSCT and fuzzy logic. Extensive experiments show that the proposed method can improve subjective and objective results compared to some other fusion approaches. ©2010 IEEE.

Data Mining & Statistics Analysis is the search for valuable information in large volumes of data. It is now widely used in health care industry. Especially breast cancer is the second most cause of cancer and the second most dangerous cancer. The best way to improve a breast cancer victim's chance of long-term survival is to detect it as early as possible. Currently there are three methods to diagnose breast cancer: mammography, FNA (fine needle aspirate) and surgical biopsy. The diagnose accuracy of mammography is from 68% to 79%, the accuracy of FNA is inconsistent with varying from 65% to 98%, the accuracy of a surgical biopsy is nearly 100%. The procedure of a surgical biopsy, however, is both unpleasant and costly. In this paper, we use a FNA with a data mining & statistics method to get an easy way to achieve a best result We combine some statistical methods such as PCA, PLS linear regression analysis with data mining methods such as select attribute, decision trees and association rules to find the unsuspected relationships. In addition, the experimental results are shown and discussed. © 2005 IEEE.

Data mining is finding hidden rules in given dataset using nontraditional methods. The objective is to discover useful or patterns from the given collection of data. This research investigates if the differences in accuracy of "time series forecasting" are related to the differences in one's cognitive style and subjective emotion. Two kinds of analyses were performed before applying data mining. Firstly, a statistical test was used to see if there was a positive correlation between a number of cognitive styles and subjective emotional states and the accuracy of time-series forecasting. This was not very revealing and the next step are to use a self-organizing neural network (SONN) to see if correlations between these variables could be discovered. The results showed that there were correlations but did not show whether the correlations were positive or negative. Finally data mining was applied to discover which cognitive styles and subjective emotions positively influence forecasting. It was found that subjects who have in analytic style and subjects who have a relaxed mode were more accurate in their judgments than those who do not these characteristics. © Springer-Verlag Berlin Heidelberg 2006.

This research had a systematic study on arm fatigue issue in free hand interaction in VR environment and explored how arm fatigue influenced free hand interaction accuracy. A specifically designed target-acquisition experiment was conducted with 24 volunteered participants (7 left-handedness, 17 right-handedness) recruited. The experiment results indicated that (1) arm fatigue resulted in short durations of hand operation, or frequent alternations of operating hand. The user’s dominant hand had a more durable operation than the non-dominant one;(2) hand operate position had a significant effect on arm fatigue level, a bent arm posture was found to be more labor-saving than an extended arm posture, (3) hand operation at a higher position (e.g., at the head height) perceived arm fatigue more easily than that at a lower position (e.g., at the waist height);and (4) arm fatigue impact hand interaction accuracy negatively. © Springer Nature Switzerland AG 2020.

In this paper, we utilize the concept of transfer learning in fruits and vegetable quality assessment. The transfer learning concept applies the idea of reuse the pre-trained Convolutional Neural Network to solve a new problem without the need for large-scale datasets for training. Eight pre-trained deep learning models namely AlexNet, GoogleNet, ResNet18, ResNet50, ResNet101, Vgg16, Vgg19, and NasNetMobile are fine-tuned accordingly to evaluate the quality of fruits and vegetable. To evaluate the training and validation performance of each fine-tuned model, we collect a dataset consists of images from 12 fruits and vegetable samples. The dataset builds over five weeks. For every week 70 images collected therefore the total number of images over five weeks is 350 and the total number of images in the dataset is (12∗350) 4200 images. The overall number of classes in the dataset is (12∗5) 60 classes. The evaluation of the models was conducted based on this dataset and also based on an augmented version. The model's outcome shows that the Vgg19 model achieved the highest validation accuracy over the original dataset with 91.50% accuracy and the ResNet18 model scored the highest validation accuracy based on the augmented dataset with 91.37% accuracy. © 2020 IEEE.

Gamification is not a newly emerging concept. Perhaps, it is a new term to some people. Gamification is a powerful new strategy to influence and motivate groups of people. It applies game mechanics to non-game activities to change the user's behavior of an application. It improves the engagement of user by keeping score of points earned through various activities on the application. The recent gamified websites or a related service such as Foursquare is a location-based application that pinpoints where you are and your activities. Users of the Foursquare can "check in" to various locations on their mobile phones and gain incentives like badges or deals. Gamification is utilised as a mean to build up user loyalty, and not so much to gain their long-term engagement. This article discusses how the gamification can help to drive the sustainability after a mobile application has been delivered and is in use. It is important to make mobile application continuously visible and sustainable if the concept of gamification has been used correctly. The more users can gain from the virtual and tangible rewards of using our application, the more we can be rewarded from our users. It also discusses how adding a "game layer" has improved the basic functions in society like educating people to become more responsible and helpful and use badges as virtual reward to users who contribute photos. Interactive mobile application designed to change the way of people report road accident cases with applying a simplicity and convenience principles. For instance, user just needs to snap photo and touch on screen to report a road accident case. © 2011 IEEE.
