We demonstrate that single-variable integrate-and-fire models can quantitatively capture the dynamics of a physiologically detailed model for fast-spiking cortical neurons. Through a systematic set of approximations, we reduce the conductance-based model to 2 variants of integrate-and-fire models. In the first variant (nonlinear integrate-and-fire model), parameters depend on the instantaneous ...

We investigated the enhanced production of nuclei formed via incomplete fusion (ICF) reactions near and above Coulomb barrier energies (5–8 MeV/A). The cross-sections evaporation residues in reactions—11B+124Sn, 10B+124Sn 11B+122Sn—were measured using off-line gamma-ray spectrometry. sum rule model (SRM) by Wilczyński et al. predicted cross-section values too low compared to our experimental re...

Thermal conductivity data acquired previously for the establishment of Standard Reference Material (SRM) 1450, Fibrous Glass Board, as well as subsequent renewals 1450a, 1450b, 1450c, and 1450d, are re-analyzed collectively and as individual data sets. Additional data sets for proto-1450 material lots are also included in the analysis. The data cover 36 years of activity by the National Institu...

This paper investigates the accuracy of rotor-locked transient-response (RLTR)-based vibration model for switched reluctance machines (SRM). RLTR is stator stimulated by abrupt change radial force when turning off one phase SRM with rotor being locked, total can be modelled as linear superposition series. An electromechanical built to clarify generation vibration, it revealed that some velocity...

A multilevel modeling approach was developed for effective prediction for performance parameters of Switched Reluctance Machine. In this approach each system is described by its most efficient model. This paper addresses the problem of multilevel modeling applied to Switched Reluctance Machine (SRM). Using field analysis magnetic characteristics and inductance profile of the SRM are obtained. T...

Introduction Switched reluctance motors (SRMs) have several advantages (rotor simplicity, high speed operation, ease of repairing, high degree of independence between phases, short end-turn, and low inertia) and used for aerospace systems, marine propulsion systems, linear drives, mining drives, hand held tools and home utility applications. However, a major disadvantage of SRM is vibration pro...

In order to improve the reliability and braking torque of aircraft electric braking system, this paper selected switched reluctance motor (SRM) as drive motor of electromechanical actuator, static torque data of SRM calculated by finite element analysis were used as training samples, then characteristics of torque-angle were obtained off-line by Generalized Regression Neural Network with partic...

OBJECTIVE To explore the mechanisms underlying the hypertropia associated with unilateral coronal synostosis. METHODS In 13 patients with unilateral coronal synostosis, we measured gaze-dependent binocular alignment before and after strabismus surgery, assessed the superior rectus muscle (SRM) pulley using computed tomography, and simulated posterior displacement of the trochlea and superolat...

The paper examines the prospects of a normative approach to institutional design for systematically introducing the concept of legitimacy to the debate on how to internationally regulate research on and possible applications of geoengineering with solar radiation management (SRM). Given the high desirability of international regulation of SRM resulting from its strong transboundary and regional...

Purpose of the paper and literature addressed: This paper aims to conceptualize supplier relationship management (SRM). It provides an overview of the objectives of SRM from the perspective of a buying company and proposes the structure of the required capabilities of the firm to obtain these objectives. The paper aggregates the previous studies on buyer-supplier relationships and participates ...
