Stochastic Gradient Descent (SGD) is a popular algorithm that can achieve state-of-the-art performance on variety of machine learning tasks. Several researchers have recently proposed schemes to parallelize SGD, but all require performance-destroying memory locking and synchronization. This work aims show using novel theoretical analysis, algorithms, implementation SGD be implemented without any locking. We present an update scheme called HOGWILD! which allows processors access shared with...

Markov Logic Networks (MLNs) have emerged as a powerful framework that combines statistical and logical reasoning; they been applied to many data intensive problems including information extraction, entity resolution, text mining. Current implementations of MLNs do not scale large real-world sets, which is preventing their widespread adoption. We present Tuffy achieves scalability via three novel contributions: (1) bottom-up approach grounding allows us leverage the full power relational...

This paper presents a detailed comparative evaluation of several direct torque control (DTC) strategies for permanent magnet synchronous machines (PMSMs), namely basic DTC, model predictive DTC (MPDTC) and with duty ratio modulation (DTC-duty). Moreover, field orient (FOC) is also included in this study. The aforementioned are reviewed their performances analyzed compared. comparison carried out through simulation 60 kW PMSM fed by two-level voltage source inverter (VSI). With the intent to...

This paper proposes a novel duty ratio modulated direct torque control (DDTC) to concurrently reduce ripple and stator flux that are typically associated with conventional (DTC). Three different methods of determination presented achieve various objectives, namely DDTC-final, DDTC-mean DDTC-rms. Additionally, adjustable error weight coefficients introduced balance the reduction reduction. Experimental results validate effectiveness proposed DDTC. Furthermore, comparative evaluation DDTC,...

The α-β possesses inherent advantage that motor during steady and transient states. An algorithm based on recursive least squares is proposed estimate...

In this article, we propose a novel quasi-sinusoidal-wave excitation scheme for switched reluctance motors (SRMs) to minimize torque ripple fully considering the high-order inductance harmonics and their phase angle difference. The production mechanism is interpreted by interaction of defined virtual currents, based on which components, influence factors, compensation principle are analyzed in detail. To reduce caused fundamental zero-axis article proposes <italic...

Clostridium butyricum (CbAgo)-based bioassays are popular due to their programmability and directional cleavage capabilities. However, the relatively compact protein structure of CbAgo limits its activity (even at optimal temperature), thus restricting wider application. Here, we observed that guide DNA (gDNA) with specific structural features significantly enhanced efficiency. Then, invented a novel gDNA containing DNAzyme segments (gDNAzyme) substantially efficency (by 100%). Using...

Detection of nucleic acids from a single multiplexed and amplification-free test is critical for ensuring food safety, clinical diagnostics, environmental monitoring. In this study, we introduced mesophilic Argonaute protein Clostridium butyricum (CbAgo), which exhibits acid endonuclease activity, to achieve programmable, system (PASS) rapid quantification at ambient temperatures in one pot. By using CbAgo-mediated binding with specific guide DNA (gDNA) subsequent targeted cleavage wild-type...

Pathogenic bacterial infections pose a significant threat to human life, health, and socioeconomic development, with those arising from Escherichia coli (E. coli) O157:H7 being particularly concerning. Herein, customized aggregation-induced emission luminogens (AIEgen)-based signaling tags (TPA-galactose) were combined microfluidic chip for the determination of E. O157:H7. TPA-galactose undergoes hydrolysis by β-galactosidase, resulting in formation highly fluorescent TPA–OH AIE...
