  A simple equivalent circuit to explain the electrical response of an ionic conductor is a parallel circuit consisting of an electrical resistance and a capacitor. Impedance semicircle of such a circuit is exactly a semicircle, but the impedance semicircle of experimental data is a depressed one. To explain this deformed shape of semicircle, usually CPE (constant phase element) is used in equi...

constructing phase diagram and its subsequent quality lines for lean gas condensate reservoirs is always crucial and challenging topic in reservoir fluid studies. due to small amounts of liquid drop-outs in lean gas condensates at reservoir conditions, full experimental tracking of phase diagram and its relevant quality lines is almost impossible for lean gas condensates.on the other hand, eos ...

Constant phase elements (CPEs) are commonly used in bioelectronic systems, to model the impedance of bioelectrodes and electrode-electrolyte interfaces. To simulate systems with an electronic design automation tool, a circuit-simulator-compatible CPE is required use circuit simulation. This paper applies rational function approximation CPEs as frequency, which able be implemented Verilog-A lang...

A generic M-ary continuous phase modulation (CPM) scheme, with a modulation index of h = 1/M, can be modeled by a continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is linear over the ring of integers modulo M. By designing a channel encoder (CE), which is a convolutional encoder, to operate over the same ring of integers modulo M, the CE and the CPE can be co...

A generic M-ary continuous phase modulation (CPM) scheme, with a modulation index of h = 1/M, can be decomposed into a continuous-phase encoder (CPE) followed by a memoryless modulator (MM), where the CPE is linear over the ring of integers modulo M. By using a channel encoder (CE), which is a convolutional encoder, to operate over the same ring of integers modulo M, the CE and the CPE can be c...

In this paper, Basic Sequential Algorithmic Scheme (BSAS) based blind Common Phase Error (CPE) compensation method is proposed to abate the effect of Phase Noise (PHN) in OFDM system to retain the system bandwidth. By using the proposed algorithm, all the signal points are grouped according to the constellation size and average angle of each group is estimated. The estimated average angles are ...

We propose Janus | a C++ template library of container classes and communication primitives for parallel dynamic mesh applications. The paper focuses on two phase containers that are a central component of the Janus framework. These containers are quasi-constant, i.e., they have an extended initialization phase after which they provide read-only access to their elements. Two phase containers ar...

the rapid melting of a semi- infinite body due to the absorption of a cw laser beam radiation has been studied. the enthalpy technique for the solution of phase change problems has been used in an explicit finite difference form to calculate the transient temperature distribution in the semi-infinite body and the growth rate of the melt pool. the technique has been modified so that it is not ne...

Considering literature of electrochemical impedance spectroscopy (EIS) it was discovered that for calculation the value double-layer capacitance (Cdl) from constant phase element (CPE) two equations, with or without solution resistance (Rs) could be used. After Cdl defined values CPE Ydl, exponent ?, Rs and charge transfer (Rct), confirmed in this work different results were obtained by includi...
