Quality control plays a key role in approximate computing to save the energy and guarantee that the quality of the computation outcome satisfies users' requirement. Previous works proposed a hybrid architecture, composed of a classifier for error prediction and an approximate accelerator for approximate computing using well trained neural-networks. Only inputs predicted to meet the quality are executed...
Graphene layers are investigated as an alternative material to tackle the interconnect scaling challenges. In this work we use large area synthetic graphene layers and evaluate layer properties in terms of sheet resistance and mean free path. The resistance of the multilayer graphene is about 60% lower compared to the single layer graphene. Mean free path yielded a maximum value of ∼60 nm for single...
Mobile applications (apps) are mostly driven by touch gestures whose interactions are natural to human beings. However, generating gesture events for effective and efficient testing of such apps remains to be a challenge. Existing event generation techniques either feed the apps under test with random gestures or exhaustively enumerate all possible gestures. While the former strategy leads to incomplete...
With the fast development of the GPU server technology, cloud gaming has become popular in recent years. Unlike the traditional desktop gaming where the graphic rendering is performed locally using the user's personal graphics card, cloud gaming runs multiple games to support many users at the same time in the data center where most of the rendering jobs are done in the remote GPU cluster. The rendered...
Smartphone applications are becoming increasingly popular. However, these applications can suffer limited power budgets or malfunctioned sensing issues from their host devices. Computation offloading addresses this issue by delegating local computation workloads to remote servers. In this paper, we present Cose Droid, a framework that supports dynamic computation- and sensing-offloading across different...
This paper studies the small signal stability of microgrids in autonomous operation with droop control. A special power flow algorithm is employed to calculate the equilibrium point (EP) of a microgrid. The dynamic model of the microgrid is linearized at different EPs which are influenced by different droop coefficients. The system eigenvalues are compared with those obtained by other methods, in...
Inverter connected renewable energy sources are becoming increasingly general in micro-grids. It has brought many problems and challenges to the stability and transient of the system. Traditional constant voltage and constant frequency (CVCF) method fits for many occasions, but it can't plug and play easily because it needs communication between the micro-grid controller and energy sources. Peer to...
The propagation characteristics of indoor full-duplex self-interference channel (SIC) at 2.6 GHz are studied and modeled. The results based on frequency-domain measurements show that the path loss exponent is 1.54. The root mean square (RMS) delay spread (DS) follows lognormal distribution at different antenna separation d. The Ricean K-factor follows Weibull distribution at different d.
This article discovers, by means of the behavioral comparative analysis of the peasant household's borrowed money of two villages of Shanxi and Wenzhou, that the peasant households' borrowed money mainly stems from the informal channel, a lot of have already been superior to the regular channel in the loan contract terms that the informal channel offered, the borrowed money interest rate of the informal...
