The processing framework of large-scale data is becoming a major concern due to an explosive growth of data intensive applications in the cloud environment, such as MapReduce/Hadoop architecture. Many virtual machines (VMs) are used for processing large-scale data of cloud applications. Therefore, the total completion time of a task is an important index to evaluate the cloud performance. The access...
A compact (125 μm × 376 μm) silicon photonic interleaver is proposed and experimentally demonstrated using loop-mirror-based Michelson-Gires-Tournois interferometer. The 3-dB and 20-dB bandwidths of the passband are ∼1.245 nm and ∼1.709 nm, respectively.
A compact DC-block broadband filter has been designed and fabricated with a simple and efficient evolutionary design process in this paper. The DC-block filter is based on parallel-coupled three-line structure which can realize a stronger coupling coefficient to reduce the stringent requirements of the line width and spacing comparing to the traditional double-line structure. The simulated fractional...
The paper presents a method of bridging the gap between GIF and HTML5 Video by providing both - allowing much faster content delivery and saved bandwidth. It's been over 25 years since the GIF format was introduced, and we've since then made significant progress in video compression. By converting GIF to video formats, you not only gain the possibility of user interaction, but you also reduce its...
This paper discusses the networked predictive control with communication delay and data loss in feedback channel under limit-bandwidth through a single value. A networked predictive control scheme is used to actively compensate for the communication delay and data loss. Based on the analysis of the closed-loop networked predictive control systems, a design strategy and detail steps is proposed. The...
To further increase the experienced data rate per user, and to overcome the poor indoor penetration and the presence of dead-spots, the network architectures with relays, picocells and femtocells underlaying the macrocell network which are commonly referred as heterogeneous networks have drawn more and more researching interests. One of the main challenges of heterogeneous networks is the severe inter-cell...
To improve the bandwidth of a micro-strip antenna used in sensing moisture contents in materials, such as soil and concrete, a design method of circular double-layer micro-strip antenna is studied in this paper. The paper introduces the circular antenna structure, the algorithm for calculating resonant frequency, and the analysis of the relationship between patch size and bandwidth. Simulation results...
A single layer, single-feed circularly polarized (CP) microstrip antenna designed with four slits equally spaced and inset at the boundary of the circular patch for Beidou (COMPASS) Navigation System is proposed. The experimental results shown that by simply tuning the lengths of the slotted pairs, two orthogonal near-degenerate resonant modes for CP radiation can be excited. The measured impedance...
Call admission control is an essential approach for traffic control and QoS provisioning. Compared with the single network, it is quite complicate for multi-service heterogeneous wireless networks. In this paper, a hierarchical joint call admission control HJCAC is proposed. The framework of the scheme, new introduced messages format and service access procedure is also designed in this paper. Simulation...
Generally, every Website provides its own resource upload and download modules for users to share resources. However, the resources uploaded to Websites' servers are often lack of unified and professional management. Whatpsilas more, when the amount of user using the upload and download modules increases, it will put a big pressure on the Websitepsilas server in term of bandwidth. To solve these problems,...
