An update on what is coming in 2017 from Wonderware with the largest Wonderware Software Evolution in 15 years.
Welcome to International Journal of Engineering Research and Development (IJERD)
This document summarizes a system for controlling robots over the Internet using human supervision. The system uses a robotic arm, cameras, and a PC controller connected to a web server. When the robot encounters a task that is too complex, it pauses and asks the human supervisor for assistance via an Internet browser. The supervisor can then help the robot complete the task. The system was tested using a laundry sorting task, where the robot sorted clothes into different baskets but could ask for help identifying ambiguous items. With human supervision, the robot was able to complete the entire sorting procedure without errors. The concept of internet-controlled robots with human assistance could enable applications in remote exploration, hazardous environments, and domestic robotics by improving reliability and consistency

A hybrid MEMS sensor is described that uses inductive telemetry for contactless, high-temperature measurements in harsh environments. The passive sensor uses a bent beam structure connected to interdigitated combs to change capacitance with temperature. It communicates wirelessly with a readout unit through coupled inductors. Testing showed the sensor's capacitance and the measured temperatures agreed well with a reference sensor up to 350 degrees C, demonstrating its effectiveness for remote, high-temperature industrial monitoring.
PROTOTYPING ECO POWER GENERATOR USING GIANT MAGNETOSTRICTION MATERIAL
This document discusses the design and testing of a Giant Magnetostriction Electric power Generator (GMEG) that converts vibration energy into electricity. The GMEG uses a Terfenol-D giant magnetostrictive material which changes shape under magnetic fields. Experimental results showed the GMEG could generate over 100W of power from a dropped metal ball and that output voltage increased with an applied preload of 8MPa to the Terfenol-D. A vibration deflector was also designed to redirect vibrations to the GMEG from different angles.
Measuring Chest Movement
This study aimed to detect and measure chest wall motion using an array of unobtrusive pressure sensors placed beneath a mattress. The pressure sensor data was compared to measurements from respiratory inductance plethysmography bands. Five participants performed different breathing patterns in various positions while sensor data was recorded. The pressure sensor signals were aligned using cross-correlation and summed to increase signal amplitude. Inspiration and expiration segments were identified and delays between signals were calculated. When corrected for delays, the pressure sensor data showed similar chest movement detection to the reference plethysmography bands, suggesting this method could enable long-term respiratory monitoring.
RADIATION HARDENED CHIPS
Radiation hardened chips are designed to resist damage from ionizing radiation like that encountered in space, around nuclear reactors, and near particle accelerators. They use techniques like hardened substrates, shielding, and error correction to prevent issues like data corruption from radiation. Major sources of damaging radiation include Van Allen belts, cosmic rays, solar particles, and nuclear reactions. Radiation hardening aims to let electronics reliably function in radiation-intensive environments like satellites and nuclear facilities.

HCL Notes und Domino Lizenzkostenreduzierung in der Welt von DLAU
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.

HCL Notes and Domino License Cost Reduction in the World of DLAU
Webinar Recording: https://www.panagenda.com/webinars/hcl-notes-and-domino-license-cost-reduction-in-the-world-of-dlau/
The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.
These topics will be covered

- Practical examples and best practices to implement right away
Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdf
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:
