A novel ultra-HIGH compliance, low power, very accurate and HIGH output impedance CURRENT output stage (COS) with extremely HIGH output CURRENT drive CAPABILITY is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18mm CMOS, BSIM3, and Level49 technology.This deliberately composed structure utilizes a well combination (for a mutual auto control action) of negative and positive feedbacks to achieve ever demanded merits such as very low power of 150mW, ultra HIGH ratio of 3000 for output CURRENT over the bias CURRENT (which is selected to be 0.5mA) at low THD of -20dB and very HIGH output impedance of 5GWwith power supplies of ±0.5V when operating at class AB mode. Simulation results with ±0.5V power supply shows an absolute output voltage dynamic range of 0.9V which interestingly provides the HIGHest yet reported output voltage compliance for CURRENT mode building blocks implemented by regular CMOS technology. Full process, voltage, and temperature variation (PVT) analysis of the circuit is also investigated in order to approve the well robustness of the structure. The transient stepwise response is also done to verify the proposed COS stability.

A new method for baseband demodulation of OQPSK has been proposed in this paper. The sampling rate is two times the Nyquist rate which is very low compared with similar demodulators. The demodulation process includes baseband mixer bank, matching filter, timing recovery and phase recovery. To fasten the process, we have used the fast convolution in matching filter. Besides, a new phase recovery method has been proposed which can be used in other phase demodulators such as QPSK. The HIGH data rate demodulator will demodulate OQPSK with data rates ranging from 1 Mega-bits to more than 500 Mega-bits per second. The experiments show that this architecture can efficiently work with performance loss less than 0. 8dB for low SNR (i. e. Eb/N0≃ 5dB) and 0. 2 dB for HIGH SNR (i. e. Eb/N0≃ 10dB).

Determining land CAPABILITY based on land suitability, climatic characteristics, and soil physical and chemical properties is considered as a method of achieving sustainable management. In this study, FAO model was used to determine land CAPABILITY. To describe the spatial results, Geographical Information System (GIS) was used. Spatial data, as maps, and descriptive data, as database table, were entered into the GIS environment. The results of CURRENT land suitability model for irrigated agriculture and garden land use showed that 64.5% was in N2 class, 17.86% in N1 class, 17% in S3 class and 0.64% in NR class. For dry farming land use, 64.5% was in N2 class, 18.86% in S3 class, 17% in S2 class, and 0.64% in NR class. For rangeland use, 32% was in S3 class, 32.5% in N1 class, and 35.5% in NR class. For forest land use, 64.5% was in N1 class and 35.5% in NR class. From overlaying the CURRENT land use map with the CURRENT land suitability map, it was found that only 25.5 % of irrigated agriculture land use, 82% of dry farming land use and 30.3% of rangeland use were consistent with their land suitability map, being exploited properly.

This paper describes a modified structural dynamics model for aeroelastic analysis of HIGH-aspect-ratio wings undergoing large deformation behavior. To achieve this objective, a moderate deflection beam model is modified with some important large deflection terms and then coupled with a state space unsteady aerodynamics model. Finite element method is used to discretize the equations of motion. A dynamic perturbation equation about a nonlinear static equilibrium is applied to determine the flutter boundary. The obtained results show good agreement in comparison with the other existing data such as HIGH-altitude long-endurance (HALE) wing and Goland wing. It is found that the present aeroelastic tool have a good agreement in comparison with valid researches and also considering the effect of the geometric structural nonlinearity and HIGHer order nonlinear terms on the flutter boundary determination is very significant.

in this research genetic diversity of 33 M7 soybean mutant lines with HIGH N2 fixation characteristic which evolved from L17 cultivar irradiated by γ ray (co-60) doses 150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivar; Clark (CL) and Williams (WI) were studied using random amplified polymorphic DNA (RAPD) markers. RAPDs established 104 major amplified products using 10 polymorphic primers. Out of 104 markers, 34 were monomorph and the remaining (70) were polymorph. To estimate the similarities amongst mutant lines, parent cultivar and commercial cultivars, the Jacard coefficient provided similarity values ranging from 0.17 to 0.79. Clustering of studied genotypes with cluster analysis method and by CL (completely linkage) algorithm resulted in 7 major groups. Regarding to the similarity matrix, the mutant lines number 32 (M32) and number 9 (M9) were closer and entirely different from parent cultivar respectively. According to the HIGH genetic variability of these mutant lines, they can use in future plant breeding programs to create desirable cultivars.

In this paper a novel very HIGH performance CURRENT mirror is presented. It favorably benefits from such excellent parameters as: Ultra HIGH output resistance (36.9GW), extremely low input resistance (0.0058W), low output (~0.18V) and low input voltage (~0.18V) operation, very low power consumption (20μW), very low offset CURRENT (1pA), ultra wide CURRENT dynamic range (150dB), and ultra HIGH accuracy (error=0.003%). The circuit has a very simple compact architecture and uses a single 1V power supply. The qualitative performance of the circuit is validated with HSPICE simulations using HSPICE TSMC 0.18mm CMOS technology.

Fe/FeO/Fe3O4 composite was synthesized by a simple solid method using ferric citrate and phenolic resin as raw materials. The reaction processes of raw materials mixture were characterized by thermogravimetric analysis (TGA) under nitrogen. X-Ray diffraction (XRD) and scanning electron microscopy (SEM) were used to investigate the structure and morphology of the products. The results showed that the obtained material was octahedral Fe/FeO/Fe3O4 composite with a size of 2-4 mm. The electrochemical performances of Fe/FeO/Fe3O4 composite as anode material were also evaluated, which exhibited a stable specific capacity of 260.3 mAh g-1 and an ideal initial coulombic efficiency of 90.8% in the range of 0.05~3 V at the 5C rate. A good rate capacity of Fe/FeO/Fe3O4 composite electrode was also shown by the charge-discharge testing even at the rate of 60C. The better rate CAPABILITY of Fe/FeO/Fe3O4 electrode could be measured in HIGHer temperature.

This paper deals with results of leakage CURRENT measurements on 20 kV porcelain insulators. The measurements were performed in a time frame of one period (50 Hz) and the insulators were contaminated from a compound of salt and kaolin. The study was made via I-U characteristic curves plotted for one cycle of voltage application. The investigation of the observed phenomena showed that the response to the applied voltage is linear at first and thereafter takes the form of CURRENT pulses. Partial discharges (streamers), short and long duration arcs are the most likely physical phenomena detected experimentally. This assumption is convincingly supported from calculations of the average energy per pulse, which was found to be close to values reported in the related literature.

In this paper, a new bidirectional buck-boost dc-dc converter with CAPABILITY of soft switching and zero input CURRENT ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input CURRENT ripple. In the proposed converter, zero voltage switching (ZVS) and zero CURRENT switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addition, the proposed topology is analyzed in all operating modes and all equations of voltage and CURRENT for components are obtained.Moreover, the required conditions for soft switching operation and also achieving zero input CURRENT ripple are calculated. Finally, the acuracy performance of the proposed converter is reconfirmed through simulation results in EMTDC/PSCAD software program.
