A log-domain current-mode true RMS-to-DC converter based on a novel synthesis of a simplified current-mode low pass filter and a two-quadrant squarer/divider is presented. The circuit employs floating gate MOS (FG-MOS) transistors operating in weak inversion region. The converter features low power(

With increasing scale and complexity of cloud operations, automated detection anomalies in monitoring data such as logs will be an essential part managing future IT infrastructures. However, many methods based on artificial intelligence, supervised deep learning models, require large amounts labeled training to perform well. In practice, this is rarely available because labeling log expensive, ...

We present several new results on minimal space requirements to recognize a nonregular language: (i) realtime nondeterministic Turing machines can recognize a nonregular unary language within weak log logn space, (ii) log logn is a tight space lower bound for accepting general nonregular languages on weak realtime pushdown automata, (iii) there exist unary nonregular languages accepted by realt...

‎This paper presents two main results that the singular values of the Hadamard product of normal matrices $A_i$ are weakly log-majorized by the singular values of the Hadamard product of $|A_{i}|$ and the singular values of the sum of normal matrices $A_i$ are weakly log-majorized by the singular values of the sum of $|A_{i}|$‎. ‎Some applications to these inequalities are also given‎. ‎In addi...

Abstract This article deals with kinetic Fokker–Planck equations essentially bounded coefficients. A weak Harnack inequality for nonnegative super-solutions is derived by considering their log-transform and adapting an argument due to S. N. Kružkov (1963). Such a result rests on new Poincaré sharing similarities the one introduced W. Wang L. Zhang in series of works about ultraparabolic (2009, ...

This paper extends the scenario of the Four Color Theorem in the following way. LetHd,k be the set of all k-uniform hypergraphs that can be (linearly) embedded into Rd . We investigate lower and upper bounds on the maximum (weak and strong) chromatic number of hypergraphs in Hd,k. For example, we can prove that for d ≥ 3 there are hypergraphs inH2d−3,d on n vertices whose weak chromatic number ...

fracture system in carbonate reservoirs is very complex. understanding the features of fractures such as dip, strike and the other parameters can help to distinguish the behaviour of reservoir in any exploration and production plan. image log is the best way to investigate feature planes like fracture and bedding. image log in one of drilled well #10x393 of bangestan reservoir in gachsaran oilf...
