Network coding is becoming a very important technology to improve the reconstructing performance of distributed storage systems due to its high reliability and low redundancy. Update is a typical and important operation involved in the network-coding-based systems. However, the overhead incurred by the update operation has a significant impact on the system performance. Traditionally, the small updated...
Bursty behavior normally indicates that the workload generated by data accesses happens in short time, uneven spurts. In order to handle the bursts, the physical resources of IT devices have to be configured to offer capability which goes far beyond the average resource utilization, thus satisfying the performance. However, this kind of fat provisioning incurs wasting resources when the system does...
The paper presents the design and implementation of input/output interface circuits, fully compatible with low-voltage differential signal (LVDS) standard. Due to the low voltage differential transmission technique, the low power consumption and high transmission speed are achieved at the same time. The transmitter is implemented by a closed-loop control circuit and an internal bandgap voltage reference,...
In this paper, the embedded based fuzzy controller is implemented and applied for a car-like mobile robot (CLMR). We present the design and implementation of a fuzzy controller by using a microcontroller. The fuzzy controller utilizes a look-up table to realize fuzzy logic algorithm. The controller of the CLMR receives the information from the IR sensor via two analog-digital converters and a control...
A multiple support vector regression (SVR) model with time lags was proposed for short term traffic flow prediction. Time lags between current traffic flow and upstream traffic flow were estimated in order to make better use of spatial-temporal correlation between the upstream and the downstream. The time lags could help identify the upstream flow series most similar to that of the current road and...
Spatio-temporal similarities, one of the characteristics to describe the relativity of traffic phenomenon, can be utilized to predict short-term traffic flow. These similarities not always appear at spatial adjacent road links because of complexity of road network. In this paper, we adopt Cross-Correlation Function to depict similarities between different traffic flow series according to the observed...
Web-based training gains popularity due to the pervasiveness of Web applications, abundant hyper media contents, and other attractive attributes. However, previous experience and research indicate that learners in Web-based learning environments tend to drop out when they lose orientation or have insufficient interaction with support providers during self-directed learning process. Formative assessment...
