In this paper, a 4-port broadband mobile phone multiple input multiple output (MIMO) antenna is designed and implemented for use in femto cell communications. The assembly consists of 4 antennas with one main antenna that covers the entire design band and 3 sub antennas that cover the data communication bands. The main antenna operates in the CDMA, GSM, LTE class 2~3 and class 33~34 service bands, and the sub antenna operates in the LTE class 1~4, and Wibro band for data communications. The voltage standing wave ratio (VSWR) was less than 3:1, and the maximum isolation between the antennas was -8.5dB over the entire design band. The average gains for the main antenna were measured from -2.48 to -0.54dBi, with efficiencies from 56.45 to 88.3% while those for the sub antennas were between -1.96 to -1.2dBi and 63.75 to 75.92%, respectively. The envelop correlation coefficient (ECC) for the MIMO system was under 0.148 over the entire data communications band.

Facial feature detection has been applied in many devices, such as cameras, smartphones, and CCTV. Most importantly, face detection should detect a face without a significant effect from external factors, such as changes in lighting, background, and so on. In this study, to be robust against external factors and to select the pattern, we propose a specified accuracy that is a better algorithm. The proposed algorithm is used to extract facial features from the LGP algorithm robust to external factors when detecting facial features. The facial features are the eyes, nose, and mouth, thereby learning by specifying a pattern. Using the training set a face is detected.

With the improvement of people's life quality, people require the higher level of the electric power communication than before. The electric power communication is the key to the safety of power grid and electric power security support. At the same time, the rapid development of power industry puts forward higher requirements on electric power communication system. Optical fiber communication technology with low weight, large capacity, low dissipation, strong anti-interference ability, especially the optical WDM optical fiber communication and optical switching function, meets the requirement of the development of digitization, and also makes electric power integrated communication ability improved. Therefore, optical fiber communication technology is widely used in electric power communication, but with the development of the society, we should strengthen the development and study of optical fiber communication technology continuously. The paper mainly explores the application and influence of optical fiber communication technology in electric power communication.

A broadband MIMO antenna, using the metal cover which is one of the antenna radiators, is designed and implemented on the PCB. A monopole and an IFA with a metal cover radiator operate simultaneously through a hybrid form of operation. The proposed antenna satisfies S-parameter -6dB at the bands of LTE class 12 ~ 14, class17, CDMA, GSM900, DCS, KPCS, USPCS, WCDMA, LTE class 40 and WiFi. The maximum ECC is 0.186 over the desire bands.

This paper aims to propose a design and architecture of a lexicon of verbs that would help in parsing visual scenes into linguistically grounded representation as well as in generating the semantic representations. To this end, we look over verb representation in linguistics for a skeleton architecture of a model and observe visual data in order to extract detailed properties embedded in visual scenes. This paper mentions early results of modeling works so we need to explorer various factors and apply them in the modeling works continuously.
