one of the most important measures, in order to increase animal products and reduce imports, is the industrialization of animal husbandry units, specially the dairy cattle. the condition of milk production would be improved by this industrialization, which is in the direction of increasing the efficiency of milk production units. the purpose of this study is calculate , the efficiency of the tr...

There are many factors that affect the change of room temperature, especially outdoor environmental factors, which makes it difficult to establish a model describe dynamic changes real time temperature. In response this problem, study proposes RC network two-node wall structure method and analyze heat conduction process building envelope. With method, we first divide envelope such as walls floo...

Background: Many elderly individuals complain of difficulty in understanding speech in noise despite having normal hearing thresholds. According to previous studies, auditory training leads to improvement in speech-in-noise perception, but these studies did not consider the etiology, so their results cannot be generalized. The present study aimed at investigating the effectiveness of envelope-b...

Censored (or truncated) observations are quite prevalent in practice. How does the existence of imperfect observations affect optimal decisions? We consider this problem in the setting of a general finite-horizon Bayesian sequential decision process. We first prove a general derivative result that resembles the classic envelope theorem. We then show that for a class of Bayesian sequential decis...

The Multi-Input Multi-Output (MIMO)Constant Envelope Modulation MIMOCEM is introduced as power and complexity efficient alternative to MIMO-OFDM for wireless backhaul networks. Due to a low resolution ADC (1-bit in the default operation) employed in the MIMO-CEM receiver, MIMO-CEM channel estimation is considered as one of the major challenges toward its real application. A block based adaptive...

In this paper a two-phase supply modulator suitable for envelope tracking power amplifier is presented. The designed supply modulator has the linear assisted switching architecture. Two-phase architecture is used in order to reduce the output switching ripples. The proposed architecture uses hysteretic control instead of pulse width modulation (PWM) which significantly reduces the circuit compl...

The control augmentation systems are very important to keep the stability and manipulability in the flight control systems. The general flight control laws are designed by static designs and dynamic fits. To improve the adaptive capability, a new method of control laws design was introduced by using dynamic optimization genetic algorithms. The control parameters were adjusted online in the flig...

We report a 75dB, 2.8μW, 100Hz-10kHz envelope detector in a 1.5μm 2.8V CMOS technology. The envelope detector performs input-dc-insensitive voltage-to-currentconverting rectification followed by novel nanopower current-mode peak detection. The use of a subthreshold widelinear-range transconductor (WLR OTA) allows greater than 1.7Vpp input voltage swings. We show theoretically that this optimal ...

Two related studies investigated the relationship between place-pitch sensitivity and consonant recognition in cochlear implant listeners using the Nucleus MPEAK and SPEAK speech processing strategies. Average place-pitch sensitivity across the electrode array was evaluated as a function of electrode separation, using a psychophysical electrode pitch-ranking task. Consonant recognition was asse...
