Wayne will sample, in 3 hours, his 3-day course. In the 3 hours, he will introduce the concept of resonant behavior of a wide range of structures (the Tacoma Narrows Bridge down to electronic circuit boards). Laboratory vibration tests on samples determine whether product design and manufacture have avoided or at least lessened resonant responses. Wayne will introduce sinusoidal as well as random vibration test standards. He will show, by slides and video clips, how we perform those standard tests by means of (1.) EH or electrohydraulic or servohydraulic shaker systems and (2.) ED or electrodynamic shaker systems, including their power amplifiers and their controllers. Part 1: How does in-service vibr damage hardware? Animation of card flexing; show chip with damaged ball grid. Why is such weakness important to QE? How do we measure in-service vibr? Why re such measurements important to QE? Seismic & Land vehicles & Ships will use on-board accelerometer sensors & recorders; explain what accelerometer is, where place, how electrical signal is on-board recorded for later study, data becomes test spec. Air vehicles on-board accelerometer sensors & telemetry much the same but record to higher frequencies and telemeter signals to ground for recording, study & becomes test spec.

IRJET- Cable Behavior in Cable Stayed Bridge due to Sudden Ground Motion

IRJET Journal

This document analyzes the behavior of cables in a cable-stayed bridge due to sudden ground motion. It describes a case study of a 200m bridge with 60m towers and 300mm cables. The bridge is analyzed under normal and impact loading conditions using Staad Pro software. The results show cable stresses increase significantly, up to 1309.477 N/mm2, when an impact load of 800kN is applied with the support released in the x-direction. However, stresses only increase nominally with the support released in the z-direction. Moment diagrams also show higher fluctuations at the tower base and cable junction under the former impact case. The conclusions are that impact loading can cause instability if the support is released in

This document discusses voltage dips/swells in power distribution systems and proposes using a Dynamic Voltage Restorer (DVR) for mitigation. It begins with an introduction to power quality issues like voltage variations and their effects. It then provides details on the basic structure and operation of a DVR, which injects voltage in series to maintain acceptable voltages. Simulation results are presented showing how a DVR can compensate for voltage dips/swells caused by changes in load conditions or upstream disturbances. The paper concludes the DVR is effective for mitigating voltage variations and maintaining power quality.

Chapter 4 Boylstead DC Biasing-BJTs.pptx

AneesSohail1

This document summarizes key concepts about biasing transistors, including: 1) Biasing establishes operating conditions like current and voltage to turn the transistor on for amplifying AC signals. Important to keep the operating point (Q-point) stable for proper transistor functioning. 2) Common biasing circuits include fixed bias, emitter-stabilized bias, voltage divider bias, and collector feedback. Emitter-stabilized and voltage divider biases are more stable against temperature and transistor parameter variations. 3) Load line analysis graphs the transistor characteristics and determines the Q-point where DC and AC signals are amplified linearly without saturation or cutoff. Biasing aims to set the Q-point in the active region for maximum

Design of Low Cost Load Cell Amplification Card

IRJET Journal

This document describes the design of a low-cost load cell amplification card. It begins with an abstract explaining that load cells produce low voltage signals that need amplification for measurement. The circuit uses three OP07 operational amplifiers to provide adjustable gain amplification of load cell signals from 0-20mV to -10V to +10V. Power is supplied by a voltage regulator circuit producing ±5V, ±12V, and 0V from a step-down transformer. PCB layouts are provided for the amplification card and power supply circuitry. The amplification gain can be adjusted using a 100k potentiometer to amplify low-level load cell signals for data acquisition.

Performance evaluation of SEPIC, Luo and ZETA converter

International Journal of Power Electronics and Drive Systems

DC-DC converters are devices which convert direct current (DC) from one voltage level to another by changing the duty cycle of the main switches in the circuits. These converters are widely used in switched mode power supplies and it is important to supply a constant output voltage, regardless of disturbances on the input voltage. In this work, the performance of three different converters such as Single-Ended Primary-Inductance Converter (SEPIC), Luo converter and ZETA converter have been analyzed. Further, the parameters values such as ripple voltage, switching losses and efficiency of the proposed three different converters were compared with each other. Also, the simulation work has been carried out using MATLAB/SIMULINK software. From the comparison of obtained results, it is observed that the ZETA converter has high significance than the SEPIC and Luo converter.

Design of Single Phase Automatic Power Factor Controller using Microcontroller

IRJET Journal

This document describes the design of a single-phase automatic power factor controller using a microcontroller. It aims to improve power factor automatically when it falls below a certain level. Low power factor results in losses in transmission lines and equipment. The system measures voltage and current using zero crossing detectors to calculate phase difference and power factor. When power factor drops below 0.95, the microcontroller activates capacitor banks to compensate for reactive power and improve power factor. Simulation results show the power factor is improved from 0.66 to 0.97 with the automatic power factor correction system.

On Duty Cycle Concept in Reliability

ASQ Reliability Division

This document discusses duty cycle concepts in reliability engineering. It begins with definitions of time-based and stress-condition-based duty cycles. Time-based duty cycle is the proportion of time a system is active, while stress-condition-based duty cycle considers the level of stress applied. The document then discusses how duty cycle manifests differently across various industries and how it is used to calculate reliability, with duty cycle affecting mission time, failure mechanisms, and characteristic life. Examples are provided for hard disk drives to illustrate the effects of duty cycle on acceleration factors and mean time to failure.

A Proposal for an Alternative to MTBF/MTTF

ASQ Reliability Division

The document discusses potential issues with using MTBF/MTTF as the primary reliability metric for the defense and aerospace industries. It argues that MTBF/MTTF provides an incomplete view of reliability across the entire product lifecycle and can result in overly optimistic assessments. The document proposes using an alternative metric called Bx/Lx, which specifies the life point where no more than a certain percentage (like 10%) of failures have occurred. This provides a more comprehensive view of reliability focused on early failures. Overall, the document advocates updating reliability metrics and practices to better reflect physical failure mechanisms.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?

Speck&Tech

ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune. Partecipate alla presentazione per immergervi in una storia di interoperabilità, standard e formati aperti, per poi discutere del ruolo importante che i contributori hanno in una comunità open source sostenibile. BIO: Sostenitrice del software libero e dei formati standard e aperti. È stata un membro attivo dei progetti Fedora e openSUSE e ha co-fondato l'Associazione LibreItalia dove è stata coinvolta in diversi eventi, migrazioni e formazione relativi a LibreOffice. In precedenza ha lavorato a migrazioni e corsi di formazione su LibreOffice per diverse amministrazioni pubbliche e privati. Da gennaio 2020 lavora in SUSE come Software Release Engineer per Uyuni e SUSE Manager e quando non segue la sua passione per i computer e per Geeko coltiva la sua curiosità per l'astronomia (da cui deriva il suo nickname deneb_alpha).

HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAU

panagenda

Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-und-domino-lizenzkostenreduzierung-in-der-welt-von-dlau/ DLAU und die Lizenzen nach dem CCB- und CCX-Modell sind für viele in der HCL-Community seit letztem Jahr ein heißes Thema. Als Notes- oder Domino-Kunde haben Sie vielleicht mit unerwartet hohen Benutzerzahlen und Lizenzgebühren zu kämpfen. Sie fragen sich vielleicht, wie diese neue Art der Lizenzierung funktioniert und welchen Nutzen sie Ihnen bringt. Vor allem wollen Sie sicherlich Ihr Budget einhalten und Kosten sparen, wo immer möglich. Das verstehen wir und wir möchten Ihnen dabei helfen! Wir erklären Ihnen, wie Sie häufige Konfigurationsprobleme lösen können, die dazu führen können, dass mehr Benutzer gezählt werden als nötig, und wie Sie überflüssige oder ungenutzte Konten identifizieren und entfernen können, um Geld zu sparen. Es gibt auch einige Ansätze, die zu unnötigen Ausgaben führen können, z. B. wenn ein Personendokument anstelle eines Mail-Ins für geteilte Mailboxen verwendet wird. Wir zeigen Ihnen solche Fälle und deren Lösungen. Und natürlich erklären wir Ihnen das neue Lizenzmodell. Nehmen Sie an diesem Webinar teil, bei dem HCL-Ambassador Marc Thomas und Gastredner Franz Walder Ihnen diese neue Welt näherbringen. Es vermittelt Ihnen die Tools und das Know-how, um den Überblick zu bewahren. Sie werden in der Lage sein, Ihre Kosten durch eine optimierte Domino-Konfiguration zu reduzieren und auch in Zukunft gering zu halten. Diese Themen werden behandelt - Reduzierung der Lizenzkosten durch Auffinden und Beheben von Fehlkonfigurationen und überflüssigen Konten - Wie funktionieren CCB- und CCX-Lizenzen wirklich? - Verstehen des DLAU-Tools und wie man es am besten nutzt - Tipps für häufige Problembereiche, wie z. B. Team-Postfächer, Funktions-/Testbenutzer usw. - Praxisbeispiele und Best Practices zum sofortigen Umsetzen
