The techniques also proved practical on a large social network of one billion edges.
Cloudsim t-drive enhancing driving directions with taxi drivers’ intelligenceEcwayt
This paper presents a smart driving direction system that leverages taxi drivers' intelligence and experience. GPS-equipped taxis act as mobile sensors to model the dynamic traffic patterns of a city. A time-dependent landmark graph models traffic patterns and experienced drivers' route choices to provide users with the practically fastest route to a destination at a given departure time. A clustering approach estimates travel times between landmarks in different time slots. A two-stage routing algorithm then computes a customized, practically fastest route for the user based on this graph and real-world trajectory data from over 33,000 taxis over three months. Evaluation found that 60-70% of routes suggested were faster than alternatives, with 20% sharing results, and on average routes
Cloudsim ranking on data manifold with sink pointsEcwayt
ECWAY Technologies provides IEEE projects and software development services from its offices in multiple cities across India. The document discusses a novel ranking approach called Manifold Ranking with Sink Points (MRSP) that addresses diversity, relevance, and importance in ranking. MRSP uses manifold ranking over a data manifold to find the most relevant objects while turning already ranked objects into "sink points" to prevent redundant objects from receiving a high rank. Experimental results on update summarization and query recommendation tasks show MRSP performs strongly compared to existing ranking approaches by better addressing the importance of diversity in ranking.
Cloudsim quality-differentiated video multicast in multirate wireless networksEcwayt
This document describes a quality-differentiated video multicast scheme for multirate wireless networks called QDM. QDM aims to provide heterogeneous clients with differentiated video qualities matching their channel conditions. It first proposes a rate scheduling model to select the optimal transmission bitrate for each video frame to maximize total visual quality subject to minimum quality guarantees. It then presents QDM, a practical protocol that constructs a cluster-based structure to characterize heterogeneity and adapts transmission rates based on video quality perceived by representative cluster heads. Simulation results show QDM can efficiently adapt to network dynamics and variable video bitrates, producing a 2-5 dB gain in average video quality over leader-based approaches.

The document proposes a power allocation scheme for statistical quality-of-service provisioning in multi-relay cognitive networks. The scheme first chooses between direct transmission or relay transmission based on channel state information. It then performs efficient power allocation according to the transmission mode under average transmit power constraints, interference power constraints, and a peak interference constraint to meet quality-of-service requirements. Simulations show the proposed scheme outperforms max-min criterion and equal power allocation policies by achieving higher throughput while involving at most two relays for transmission.

This document discusses using a chopper circuit to control the speed of a DC motor. A chopper circuit uses MOSFETs to vary the voltage applied to the motor, allowing for remote speed control. This method is more efficient and compact than previous variable resistor and transformer-based controls. Pressing buttons on the chopper circuit varies the MOSFET firing angle, decreasing motor speed as the firing angle increases. The chopper control reduces motor current, losses, temperature, noise, and increases lifetime compared to DC operation.

The document discusses a channel assignment algorithm for throughput optimization in multi-radio wireless mesh networks using network coding. It formulates the joint problem of random network coding, channel assignment, and broadcast link scheduling while taking into account opportunistic overhearing, interference constraints, coding constraints, number of channels, radios per node, and fairness between unicast connections. An auction-based suboptimal solution is developed for overall network throughput optimization.

The document discusses channel allocation and routing in hybrid multichannel multiradio wireless mesh networks. It proposes an Adaptive Dynamic Channel Allocation (ADCA) protocol that considers both throughput and delay optimization in channel assignment.

Simulation results show that ADCA reduces packet delay significantly without degrading throughput, and the hybrid architecture adapts better to changing traffic than static-only architectures with lower overhead and delay than existing hybrid network approaches.

Capacity of hybrid wireless mesh networks with random a psEcwayt
This paper proposes a hybrid wireless mesh network (WMN) architecture that allows the backbone to utilize random connections to access points (APs) in a wireless local area network (WLAN). Theoretical analysis shows that the capacity of a three-tier hybrid WMN is affected by the number of mesh router cells connected to APs, the ratio of access link bandwidth to backbone link bandwidth, and traffic balance among routers with AP access. Simulation results demonstrate that configuring APs and balancing traffic can significantly improve network capacity in the proposed hybrid architecture by taking advantage of wired connections through APs.

Binary Division Power Models for High-Level Power Estimation of
FPGA-Based DSP Circuits
Abstract
Power models are at the heart of high-level estimation methods used for industrial
power evaluation of FPGA-based electronic designs. In this paper, probabilistic power
estimation models of binary divider IP cores implemented in re-configurable logic are
presented. The models are ready for use at the algorithmic and RTL levels of the design flow
and are simulation-independent, thus resulting in fast estimation times. The only parameters
the model needs are the bit-widths of the operator inputs and their signal statistics: mean
values, variances and autocorrelation coefficients. Based on these parameters and taking into
account the particular logic structure of the binary divider cores, analytical probabilistic
formulas are used to calculate the overall switching activity in the circuits—themain cause of
dynamic power consumption. Estimates are compared with both real on-board measurements
and estimates from the simulation-based tool XPower from Xilinx. Results show that the mean
relative estimation errors are within 10% of on-board measurements or low-level estimates,
and the average time to obtain power estimates using the proposed models is only 135 ms.
