Computing with large die-size graphical processors, that involves huge arrays of identical structures, in the late CMOS era is abounding with challenges due to spatial non-idealities arising from chip-to-chip and within-chip variation of MOSFET threshold voltage. In this paper, we propose a software-framework using machine learning for in-situ prediction and correction of computation corrupted due to threshold voltage variation of transistors. Semi-supervised training is imparted to a fully connected cascade feed-forward (FCCFF) neural network (NN). This FCCFF-NN then creates an accurate spatial map of faulty processing elements (PE), which are avoided in computing. Besides correcting spa...

Ark is an implementation of a consensus algorithm similar to Paxos[7] and Raft[11], designed as an improvement over the existing consensus algorithm used by MongoDB and TokuMX. Ark was designed from rst principles, improving on the election algorithm used by TokuMX, to x deciencies in MongoDBs consensus algorithms that can cause data loss. It ultimately has many similarities with Raft, but diverges in a few ways, mainly to support other features like chained replication and unacknowledged writes.

Geotechnical investigation of natural slopes is challengeable especially whennatural slopes having higher gradients and access is difcult. Also, it is even more prob-lematic to nd the shear strength parameters spatially to evaluate the stability of slopes asmost of the methods available to nd the shear strength parameters in the literature areuneconomical or such methods cannot be applied in vegetated slopes. Recently, authorshave conducted a series of in situ investigations based on the newly developed lightweightdynamic cone penetrometer to examine its applicability in analyzing the slopes coveredwith weathering remnants of decomposed granite. Six patterns were identied based on thepene...
