Generalized Trigonometric Functions [PDF]

, 2014
A new trigonometric functions called generalized trigonometric functions are defined by system of first order nonlinear ordinary differential equations with initial conditions. This system is related to the Hamilton system.

k-Fractional trigonometric functions [PDF]

, 2014
Based on the k-Mittag-Lefler function and the k-α-Exponential Function we introduce families of functions that allows us define new fractional trigonometric functions that contain the classical trigonometric functions as particular case for some ...

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

SmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Improving Human Diving Endurance With a Field‐Deployable Exoskeleton

SmartBot, EarlyView.
High energetic demands to overcome drag, combined with a finite supply of self‐contained breathing gas, fundamentally limit human endurance in underwater locomotion. Here, we present DiveMate, a portable exoskeleton that provides adaptive bidirectional assistance synchronized with fin‐kicking during diving, reducing lower‐limb muscle activation and ...

ANEForge: Python for Direct Computation on the Apple Neural Engine

Software: Practice and Experience, EarlyView.
ABSTRACT Background The Apple Neural Engine (ANE) is the fixed‐function neural accelerator on every recent Apple device, and the only sanctioned route to it is CoreML. CoreML treats the engine as a scheduling option: no configuration requires it, the CPU remains a permitted fallback, and no runtime interface reports which unit ran a call.

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

Structural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Understanding STEM Coursetaking Among English Learner Subgroups: Longitudinal Evidence From Four State Policy Contexts

TESOL Quarterly, EarlyView.
Abstract Although a substantial body of research documents the problem of course tracking for students classified as English learners (ELs), very little work has addressed the notably different challenges that subgroups of ELs face across different state policy contexts.

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

High Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

Review on Distributions Generated Using Trigonometric Functions

Austrian Journal of Statistics
In the present scenario, researchers are interested in developing new distributions based on trigonometric functions to model data.  Previously, data modelling was commonly done with standard and existing distribution functions.
