Introduction: Designer Cannabinoids is a newly emerging drug of abuse that gained popularity among adolescent and young adults in the past few years. These drugs are marketed as incense or potpourri under different brand names such as spice. The potency of these drugs is variable and the range of adverse effects range from simple to severe and life threatening adverse effects such as myocardial...

The static and dynamic response of a fluorescent lamp operating at high frequency was studied and modeled by a SPICE-compatible behavioral equivalent circuit. Good agreement was found between model simulations and experimental results. It was also found analytically that the proposed model predicts a zero at the right half-side of the complex plane as observed experimentally.

This paper deals with an electrical modelling and optimization of a thermal energy harvester dedicated to power autonomous systems. Such devices based on bimetal strips and piezoceramics turn thermal gradients into electricity by a two-step conversion mechanism. This work focuses first on a demonstration of a ST-WSN (GreenNet demonstration platform) supplied by the harvester to validate, for th...

We discuss several elements of statistical SPICE models and present our solutions. We present (i) a solution of automatically detecting Monte Carlo vs. skewed simulations, (ii) a method of modeling an arbitrarily given asymmetric or symmetric distribution, (iii) a hierarchical structure of the skewing parameters of many process/device statistical distributions for skewed simulations, (iv) a tec...

Abstract Accurate snowfall measurements are necessary for meteorology, hydrology, and climate research. Typical uses include creating calibrating gridded precipitation products, the verification of model simulations, driving hydrologic models, input into aircraft deicing processes, estimating streamflow runoff in spring. These applications significantly impacted by errors solid measurements. Th...

Though rather awkward and limited in its usage, SPICE has been used by several authors solving their various optimisation problems. In this paper we propose how some generic optimisation algorithms can be integrated into SPICE. The implemented program has proven to be an extremely efficient optimisation tool for an experienced circuit designer. It is free of charge available at our web site (ht...

A comprehensive large-signal MESFET model that provides a realistic description of measured characteristics over all operating regions is presented. It describes subthreshold conduction and breakdown. It has frequency dispersion of both transconductance and drain conductance, and derates with power dissipation. All derivatives are continuous for a realistic description of circuit distortion and...

Process improvement models include the best practices from relevant disciplines in comprehensive sets. Their purpose is to convey knowledge that will help organizations through their process improvement journey. In this paper we argue that process improvement practitioners do not take advantage of this knowledge. Hence we propose a process to evaluate and extract knowledge form a process model ...

A mathematical model of the prototype of memristor, manufactured in 2008 in Hewlett-Packard Labs, is described in the paper. It is shown that the hitherto published approaches to the modeling of boundary conditions need not conform with the requirements for the behavior of a practical circuit element. The described SPICE model of the memristor is thus constructed as an open model, enabling addi...

This paper presents empirical models to estimate the propagation delay time and power consumed by DCFL digital circuits implemented with HFETs. Model parameters are selected performing sensitivity analysis over SPICE simulations. Sensitivity is also exploited in developing the model equations. A maximum relative error of 7% has been obtained.
