A dual-feed small-size penta-band PIFA for LTE/WWAN mobile handset applications is presented. The proposed PIFA is composed of a simple U-shaped patch with dual-shorting pins connected to the ground plane. The patch, having a low profile of 5 mm, has dimensions of about 10 × 35 mm2. The antenna is excited at one arm of the U-shaped radiating patch to cover the higher band of GSM1800/1900/UMTS2100/LTE2300/2500, while it is excited at the other arm to realize the GSM900. In this way, the proposed PIFA achieves enhanced bandwidth coverage with no increased dimensions and additional active switches. In addition, the matching networks, employed on both feeds, ensure a high electrical insulation between the low and the high frequency bands, covered by the antenna. The measured antenna efficiency is 45%50% and over 60% for the lower band and the higher band, respectively. A prototype of the proposed PIFA with dual-feed and dual-shorting pins was fabricated. The measured results including reflection coefficients and radiation characteristics are presented. © 2014 Mingyang Liu and Bin Zhao.

In recent years, with the rapid development of the World Wide Web, huge amount of data arises in our daily life. Which approach should be taken to assist users when searching the information they need is the point. For users, when facing the same resources, they more commonly annotate them or input search queries according to their own perspectives. This process has been already proven as a time-consuming. Based on the goal, we propose our methodology that to combine user's context, users' profile with users' Folksonomies together to optimize personal search. And at the end of this paper, we make an experiment to evaluate our methodology and which performs better. © 2015 IEEE.

Food security has become a big issue in China for some big incidents occurred in recent years. happened. This study has a survey on these cases and analyzes the reasons from the aspect of enterprises and government. Some solutions are put forward to solve the problems about food security and business credit crisis in China currently. The purpose is to guide enterprises to set up a sound operation system and gain long-term profits. © Maxwell Scientific Organization, 2015.

It is really a challenging task to find the original video clip of a distorted duplicate among a large scale database efficiently since there are numerous variations between the original video and its copies. The difficulty mainly lies in handling the transformations while maintaining an acceptable efficiency. In this paper, an improved method for eliminating false matches both in pre-processing step and refinement step is proposed to obtain high efficiency as well as accuracy. SIFT feature points are quantized by dividing its orientation to eliminate the false matches obtained by visual index match and reduce the time cost of the later refinement. An improved method for spatial and temporal verification is proposed. In order to accelerate the frame-level verification, we concatenate weak geometric consistent algorithm and traditional 4D Hough Transform methods. And in temporary verification, a 5D Hough transform is adopted in temporal images grouping, which estimates the consistent transformation parameters from different image groups and further improves the accuracy of this detection system. We evaluate our system on the dataset of TRECVID2011 Copy Detection subject, and gains a promising performance which brings a 0.1 improvement of the NDCR measure.

In recent years there are some food incidents happened in China, especially in meat product industry, which caused great panic among people. This study lists some of the cases and analyzes the influence from different angles. It illustrates how to supervise processing and producing meat products under the technology of Internet of things, like sensor, RFID and trackers etc. The purpose is to offer a safe food environment in China and lead enterprises to set up a sound operation system to gain long-term profits as well. © Maxwell Scientific Organization, 2015.

In ubiquitous game, the interactions between the real world and the virtual world are known and are generally a consequence of the design of a reactive system. This analysis is to lead us to find some basic design essentials to conceive a ubiquitous game with an extended immersion for the user, by combining ideas used in the immersion and avatar theory. In this research, after analyzing all the prior design solutions with respect to their sufficiency in term of immersion, a new method based on the user model is proposed to achieve different degrees of immersion. This theory could be used by designers as the ground to develop the ubiquitous games or ambient entertainment applications. © 2011 Springer-Verlag.

The development of high-tech, smart phones are not only the tools for people to convey information but also a popular guard to protect one's accounts, especially through online payment. But the network of smart phones is not perfect for any operations which deal with money. As it is seen that there are more potential threats when lopns or passwords are put into one's smart phone keyboard to get into his internet account. Based on the working procedure of smart phones as the payment tool, this study tries to analyze the security problems of smart phone password from the perspective of M-banking. The purpose is to raise the safety awareness of online banking users and offer some solutions to the banks as well. © 2015 Academic Journals Inc.
