great effect of three way catalytic convertor (twc) performance on oxygen sensor output voltage has made the sensor (located after catalyst) as the main signal in almost all today’s twc monitoring algorithms. in this paper output voltage of nonlinear oxygen sensor is estimated using a nonlinear autoregressive with exogenous inputs (narx) model. the estimation uses ecu calculated exhaust gas flo...

Microgrids need control strategies to achieve maximum performance. An appropriate strategy should have high performance in unbalanced conditions addition normal conditions. Today, the use of microgrids, with a variety power sources, including solar, wind, diesel, energy storage sources increase capability distribution grid has made significant progress. However, controlling and managing their e...

A single multi-plane light convertor (MPLC) is applied to simultaneously mitigate turbulence-induced crosstalk and demultiplex two orbital angular momentum (OAM) multiplexed channels for a free-space optical link. Comprised of six programmable phase planes, the MPLC placed at receiver side turbulence mitigation channel demultiplexing. Propagating through cascaded coaxial turbulence-distorted OA...

This paper presents the performance investigation of multi-phase voltage source inverter (VSI) with simple PWM switching techniques namely the harmonic injection and offset injection method. The technique discussed in this paper is easy to implement and avoid complicated controlling algorithm adapted in SVPWM technique. A generalized algorithm suitable for odd number of phases is developed in M...

In this paper we describe the statistical machine transliteration system of Amirkabir University of Technology, developed for NEWS 2011 shared task. This year we participated in English to Persian language pair. We use three systems for transliteration: the first system is a maximum entropy model with a new proposed alignment algorithm. The second system is Sequitur g2p tool, an open source gra...

A new high speed Nd:YAG Thomson scattering AD Convertor (HYADC) that can directly convert the detected scattered light signal into a digital signal is under development. The HYADC is expected to improve a signal to noise ratio of the Nd:YAG Thomson scattering measurement. The data storage of the HYADC which is required for the direct conversion of whole plasma discharge is drastically reduced b...

Spectrum efficient data transmission is of key interest for high capacity optical communication systems considering the limited available bandwidth. Transmission of the high speed signal with higher-order modulation formats within the Nyquist bandwidth using coherent detection brings attractive performance advantages. However, high speed Nyquist signal generation with high order modulation form...

A highly sensitive weak current detection circuit for implantable glucose monitoring is presented. The circuit consists of a current splitter, an integrator, a sampling/holding (S/H) circuit, and an 8-bit successive approximation register (SAR) analog-to-digital convertor (ADC). T-switches, source voltage shifting and correlated double sampling (CDS) technology are adopted to reduce the effects...

Recently, Microsoft introduced a game interface called Kinect for the Xbox 360 video game platform. This interface enables users to control and interact with the game console without the need to touch a controller. It largely increases the users’ degree of freedom to express their emotion. In this paper, we first describe the system we developed to use this interface for sound generation and co...

Code-switching is known to be a widespread phenomenon among bilinguals and in ESL/EFL teaching/learning process; it refers to any alternate use of two codes or languages within the same conversation or even the same utterance. The present study is an attempt to investigatethe functions, types and frequencies of code switching in students discourse in the context of ELT classrooms.The study also...
