During World War 1, the French government tightly controlled information and spread propaganda to influence public opinion about the war. The censorship prevented French citizens from learning truthful information, so rumors spread instead. The government established a propaganda system through military journalists who invented positive information to encourage donations for the army and boost public morale. Propaganda used patriotic symbols and stereotypes of countries. It presented an overly optimistic view of how the war was going to maintain civilian support. The government even subjected schools and children to propaganda to hide the real misfortunes of war and promote victory over the depicted cowardly Germans.

The document discusses a proposed new power converter architecture for microinverters that incorporates a multilevel energy buffer and voltage modulator (MEB). The MEB aims to improve the efficiency of the high-frequency inverter stage by compressing its operating range and providing twice-line-frequency energy buffering between DC and AC. It shares benefits of both variable-topology cascade converters and switched-capacitor energy buffers. The proposed system is intended to address challenges with microinverter design like improving efficiency at high switching frequencies while reducing component counts and control complexity.

A Fast-Acquisition All-Digital Delay-Locked Loop Using a Starting-Bit Prediction Algorithm for the Successive-Approximation Register
This brief presents a fast-acquisition 11-bit all-digital delay-locked loop (ADDLL) using a novel starting-bit prediction algorithm for the successive-approximation register (SBP-SAR). It can effectively eliminate the harmonic lock and the false lock. The achievable acquisition time is within 17.5-23.5 or 17.5-32.5 clock cycles when the ADDLL works at the low or high clock rate, respectively. The digital-controlled delay line and the SBP-SAR of the ADDLL chip are synthesized using Taiwan Semiconductor Manufacturing Company's (TSMC's) 0.18-μm CMOS cell library. The proposed ADDLL can operate at a clock frequency from 60 MHz to 1.1 GHz.

A fast fault tolerant architecture for sauvola local image thresholding algor...LeMeniz Infotech
This document describes a proposed stochastic implementation of the Sauvola local image thresholding algorithm to reduce area, power consumption, and faults compared to a conventional implementation. The stochastic implementation converts pixel values and intermediate results to stochastic bit streams, uses stochastic multiplying counters (SMCs) to calculate averages and standard deviations in parallel, and a stochastic comparator to determine binary output values. Experimental results using Xilinx 14.2 show the stochastic implementation requires less time, area and power while being more fault tolerant.

A Dynamically Reconfigurable Multi-ASIP Architecture for Multistandard and Multimode Turbo Decoding
The multiplication of wireless communication standards is introducing the need of flexible and reconfigurable multistandard baseband receivers. In this context, multiprocessor turbo decoders have been recently developed in order to support the increasing flexibility and throughput requirements of emerging applications. However, these solutions do not sufficiently address reconfiguration performance issues, which can be a limiting factor in the future. This brief presents the design of a reconfigurable multiprocessor architecture for turbo decoding achieving very fast reconfiguration without compromising the decoding performances.

Interleaved digital power factor correction based on the sliding mode approachLeMeniz Infotech
Interleaved Digital Power Factor Correction Based on the Sliding-Mode Approach
This study describes a digitally controlled power factor correction (PFC) system based on two interleaved boost converters operating with pulsewidth modulation (PWM). Both converters are independently controlled by an inner control loop based on a discrete-time sliding-mode (SM) approach that imposes loss-free resistor (LFR) behavior on each cell. The switching surface implements an average current-mode controller so that the power factor (PF) is high. The SM-based digital controller is designed to operate at a constant switching frequency so that the interleaving technique, which is recommended for ac-dc power conversion systems higher than 1 kW, can be readily applied. An outer loop regulates the output voltage by means of a discrete-time proportional-integral (PI) compensator directly obtained from a discrete-time small-signal model of the ideal sliding dynamics. The control law proposed has been validated using numerical simulations and experimental results in a 2-kW prototype.

Bumpless control for reduced thd in power factor correction circuitsLeMeniz Infotech
Bumpless Control for Reduced THD in Power Factor Correction Circuits
It is well known that power factor correction (PFC) circuits suffer from two fundamentally different operating modes over a given AC input cycle. These two modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM), have very different frequency-response characteristics that can make control design for PFC circuits challenging. The problem is exacerbated by attempts to improve efficiency by dynamically adjusting the PWM switching frequency based on the load. Adjusting the PWM frequency based on the load limits controller bandwidth and restricts dynamic performance. Prior work has made use of multiple controllers, however, they have not addressed the discontinuity (bump) that exists when switching between controllers. In this paper, bumpless controllers will be synthesized for a 750 watt, semi-bridgeless PFC for the CCM-DCM operating modes.

A bidirectional single-stage three-phase Rectifier with high-frequency Isolation and power factor Correction
This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated with the three-state-switching cell (3SSC), whose power flow between the primary and secondary sides is controlled by the phase-shift angle. A theoretical analysis is presented and validated through simulation and experimental.

A bidirectional three level llc resonant converter with pwam controlLeMeniz Infotech
A Bidirectional Three-Level LLC Resonant Converter With PWAM Control
This paper proposes a bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it can achieve wide voltage gain range by switching among these three modes, which is attractive for energy storage system applications needing wide voltage variation. The proposed topology operates with constant switching frequency, which is easy to implement with digital control, and it can achieve soft switching for all the switches and diodes in the circuit as a conventional LLC resonant converter. The performance of the proposed converter is validated by the experimental results from a 1-kW prototype with 20 A maximum output current.

This document describes a proposed transformer-less inverter topology for grid-tied photovoltaic systems. The existing dual-parallel buck converter topology has issues where the grid can short circuit if there is no dead time between switches. The proposed topology addresses this by using six MOSFET switches and six diodes in a configuration that allows reactive power injection while overcoming reliability issues. It has advantages like utilizing only MOSFET switches, low leakage current, and not requiring PWM dead times. The proposed single-phase inverter is intended for grid-tied PV applications.

Highly Reliable Transformerless Photovoltaic Inverters With Leakage Current and Pulsating Power Elimination
This paper presents a transformerless inverter topology, which is capable of simultaneously solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) systems. Without adding any additional components to the system, the leakage current caused by the PV-to-ground parasitic capacitance can be bypassed by introducing a common-mode (CM) conducting path to the inverter. The resulting ground leakage current is therefore well controlled to be below the regulation limit. Furthermore, the proposed inverter can also eliminate the well-known double-line-frequency pulsating power that is inherent in single-phase PV systems. By properly injecting CM voltages to the output filter capacitors, the pulsating power can be decoupled from the dc-link. Therefore, it is possible to use long-lifetime film capacitors instead of electrolytic capacitors to improve the reliability of the PV system. The mechanism of leakage current suppression and the closed-loop control of pulsating power decoupling are discussed in this paper in detail. A 500-W prototype was also built and tested in the laboratory, and both simulation and experimental results are finally presented to show the excellent performance of the proposed PV inverter.

Grid current-feedback active damping for lcl resonance in grid-connected volt...LeMeniz Infotech
Grid-Current-Feedback Active Damping for LCL Resonance in Grid-Connected Voltage-Source Converters
This paper investigates active damping of LCL-filter resonance in a grid-connected voltage-source converter with only grid-current feedback control. Basic analysis in the s-domain shows that the proposed damping technique with a negative high-pass filter along its damping path is equivalent to adding a virtual impedance across the grid-side inductance. This added impedance is more precisely represented by a series RL branch in parallel with a negative inductance. The negative inductance helps to mitigate phase lag caused by time delays found in a digitally controlled system. The mitigation of phase-lag, in turn, helps to shrink the region of nonminimum-phase behavior caused by negative virtual resistance inserted unintentionally by most digitally implemented active damping techniques. The presented high-pass-filtered active damping technique with a single grid-current feedback loop is thus a more effective technique, whose systematic design in the z-domain has been developed in this paper. For verification, experimental testing has been performed with results obtained matching the theoretical expectations closely.

Delay-Dependent Stability of Single-Loop Controlled Grid-Connected Inverters with LCL Filters
LCL filters have been widely used for grid-connected inverters. However, the problem that how time delay affects the stability of digitally controlled grid-connected inverters with LCL filters has not been fully studied. In this paper, a systematic study is carried out on the relationship between the time delay and stability of single-loop controlled grid-connected inverters that employ inverter current feedback (ICF) or grid current feedback (GCF). The ranges of time delay for system stability are analyzed and deduced in the continuous s-domain and discrete z-domain. It is shown that in the optimal range, the existence of time delay weakens the stability of the ICF loop, whereas a proper time delay is required for the GCF loop. The present work explains, for the first time, why different conclusions on the stability of ICF loop and GCF loop have been drawn in previous studies. To improve system stability, a linear predictor-based time delay reduction method is proposed for ICF, while a time delay addition method is used for GCF. A controller design method is then presented that guarantees adequate stability margins. The delay-dependent stability study is verified by simulation and experiment.

Pass byo bring your own picture for securing graphical passwordsLeMeniz Infotech
This document describes PassBYOP, a new graphical password scheme that uses live video of a physical token (such as a photo on a mobile phone) rather than static digital images. Three feasibility studies examine its reliability, usability, and security against observation attacks. Results found passwords based on image features to be viable, with task times and error rates comparable to prior schemes. Using a user-owned physical token increased security against observation without additional user burden, showing promise for more secure graphical passwords.
The document discusses analyzing ad library updates in Android apps. It finds that almost half of Android apps underwent ad library updates over a 12 month period, where an ad library was added, removed, or updated. For nearly 14% of app updates with an ad library update, no changes were made to the app's core functionality, suggesting maintaining ad libraries requires substantial effort. The proposed system compares how apps are updated over time to determine if an update includes ad library changes, core changes, or both.
