Dancing is always challenging especially for beginners who may lack sense of rhythm. Salsa, as a popular style of dancing, is even harder to learn due to its unique overlapped rhythmic patterns made by different Latin instruments (e.g., Clave sticks, Conga drums, Timbale drums) together. In order to dance in synchronization with the Salsa beats, the beginners always need prompts (e.g., beat counting...
In order to study the thermal adaptability of piezoelectric actuated tracked mobile system, a theoretical model is developed for investigating the effect of ambient temperature on the characteristics of piezoelectric actuated tracked mobile system based on finite element method and Coulomb's friction law. In the analysis, the temperature-dependent mechanical properties of materials, thermal stress...
A compact dual-broadband antenna is proposed for 2G/3G/LTE (4G) mobile communications. The radiation unit of the proposed antenna consists of a lower-band element and an upper-band element. The lower-band element comprises a rectangular patch fed by an L-shaped probe, the upper-band element comprises a pair of two folded printed dipole fed by an L-shaped probe as well. The upper-band element is stacked...
On validating the performance of small-sized, multi-functionalized and complicated mobile antenna on motherboard efficiently, an improved scheme with combination of the Method of Momentum (MOM) and the Fast Multipole (FMM) is proposed in this paper. The essence of this newly forwarded scheme is apt to categorize the engaged base functions into one near field group and one far field group, the MoM...
With the development of mobile communication key technology, the wireless channel condition has become an important factor to constraint the quality of wireless communication. The wireless channel measurements and modeling of the corridor at 900MHz and 1800MHz is mainly investigated based on the method of Shooting and Bouncing Ray (SBR) in this paper. Some multiple-path parameters are obtained in...
The Windows CE registry plays a very important role from physical memory and contains lots of important information that are of potential evidential value in forensic analysis. Memory acquisition and analysis is the most important in Windows CE devices forensic. The paper introduces physical memory acquisition and analysis methods in Windows environment and the procedure of memory analysis on the...
In this paper, a multi-band mobile antenna in specific for mobile terminal is come forward to support multiple communication systems. The antenna proposed herein is configured primarily by a notched planar inverted-F (PIFA) structure, an L-shaped parasitic branch element, and an inverted-L strip that is seen independently mounted on ground plane. The antenna is able to reduce antenna size by 38% compared...
Channel estimation is an important technical issue in mobile communication system, the performance and capacity of mobile communication system are directly influenced by the speed and precision of channel estimation. This paper introduced the definition and the method currently existed of channel estimation firstly, and then proposed a method based on the probability of gain difference by the feature...
Instead of the original wired IP networks, the mobile networks are used as the return channel in IP-QAM VOD system to take the advantage of their wireless data communication function and full coverage in cities. The mobiles are used as a virtual remoter of STB for demanding video programs and controlling their playing. The function of complex query for programs can be realized based on the mobile's...
Mobile informational strategy has a higher demand on the network supporting system and aims at the implementation of user oriented service management. As the indexes of customer perception are the direct reflection of the network quality, it is particularly important to analyze the indexes. In this paper, varieties of factors affecting customer experiences on the network quality are analyzed. A customer...
Wireless Mesh Networks (WMNs) are envisaged to be a key enabling technology for next generation wireless networks. The mesh nodes form the backbone connectivity, performing the dual tasks of packet forwarding as well as providing network access to the mesh clients. In this paper we present a new MAC protocol based on a star-mesh topology, which is compatible with the IEEE 802.16e-2005 Orthogonal Frequency...
