Hello, I am seeking assistance in finding information regarding the behavior of electricity, both direct current (DC) and alternating current (AC), in seawater. Specifically, I am interested in understanding how far electricity travels underwater and what effects it has on marine life. As I delve into this topic, I would appreciate any guidance on the following aspects: 1. **Distance of Electricity Travel**: How far does electricity travel underwater, and what factors influence its propagation? Are there any specific conditions or circumstances that affect the distance it can travel? 2. **Effects on Marine Life**: What are the known effects of electricity on marine life? Are there any documented cases of harm or disruption to marine ecosystems due to electrical currents? Are there any species that are more susceptible to these effects? Your expertise and insights would be invaluable in helping me better comprehend the behavior of electricity underwater. If you could provide any relevant resources, studies, or references, I would greatly appreciate it. Thank you for your time and consideration. Humberto

🌟 Thank you to everyone who joined our recent sessions on best practices for tolerances in design! It was fantastic to see such engagement and enthusiasm for this critical aspect of product development. In case you missed it, here are some key takeaways: 🔍 Common Tolerance Issues: Tolerance confusion is widespread in product design and manufacturing, impacting performance and cost. 🛠️ Designer Challenges: Avoiding insufficient, unnecessarily tight, or impossible-to-hold tolerances is crucial to prevent design flaws and cost overruns. 🏭 Manufacturing Factors: Achieving final tolerances involves managing variance, careful tooling/process selection, and monitoring tool/equipment wear. 🔬 Quality Inspection: Overcoming challenges with measurement statistics, automation, and utilizing tools/gauges for compliance checks. 💡 Key Takeaways: There’s no one-size-fits-all approach to tolerances, but clear communication, understanding documentation, and interdepartmental collaboration are crucial. Incorporating tolerance considerations into Design for Manufacturing (DFM) enhances overall efficiency. Stay tuned for more valuable insights and expertise to empower your success in design and manufacturing.

5 things I wish I had known about LEV (Local Exhaust Ventilation) before I started in the industry; 1. Legally, it's not just a "nice to have". It's compulsory in specific sectors. 2. One size doesn't fit all here. Just like a bespoke suit, each LEV system is customised to its space, function and the safety of those working around it. 3. Maintenance is key. Preventive measures can save you from significant future costs. 4. It directly impacts worker health. Underestimating it could mean severe health risks. 5. There's more to LEV than meets the eye. It's a blend of science, engineering and regulations all working in harmony. Delving into the world of LEV is fascinating, yet complex. Always question, study and explore to keep up-to-date with the dynamic industry. To the LEV enthusiasts, what's the one thing you'd like to know more about? Thank you for your kind assistance Aminin Al-Fatihin Zainudin

Careful when considering the stability of products--especially when it concerns the effectiveness of something like a sunscreen--and the intended storage!

A review article on "Recent developments in stretchable and flexible tactile sensors towards piezoresistive systems: A review" has been published. If this topic interests you, then please go through the link below: https://lnkd.in/dYS9xdDC I thank Prof. Karali Patra for his constant guidance and support in writing this detailed and informative article.

New paper online in Medical Image Analysis! You should definitely read this one, the take home message is simply great! Introducing weak masks of anomalous areas as an additional target in lesion segmentation models aids A LOT to improve results. We tried it in OCT scans of many different datasets and for multiple types of lesions. Thanks Philipp Seeböck for inviting me to collaborate in this project!

I am excited to share that the final part of my Doctoral Thesis has just been published! 📚✨ 🙏 a big thank you to my supervisors and collaborators: Konstantinos Tatsis, Roland M. Hohensinn, John Clinton, Eleni Chatzi, Markus Rothacher 🔬 Title: Unscented Kalman Filter-Based Fusion of GNSS, Accelerometer, and Rotation Sensors for Motion Tracking 📄 What is it about? In seismology or structural monitoring, we often face the challenge of measuring vibrations that vary immensly. The motion of interest spans a very broad frequency band, from kHz up to daily or even yearly variations. Additionally, the amplitudes range from being imperceptible to the human eye to visible and permanently displacing fault lines. On top of all that, the traditional translational sensors such as accelerometers and GNSS antennas and receivers are sensitive to rotational motion. Our paper introduces the well-known method, the Unscented Kalman filter, for new applications in seismology and structural monitoring. It enables the fusion of both accelerometer data and GNSS positions while simultaneously correcting for rotation-induced errors. This fusion scheme then provides displacement, velocity and rotation time series across a broad frequency band and in near real-time. 🔗 Link to Paper: https://lnkd.in/dH9FhEAv

🚀 Exploring Advanced Control Systems!🎯 I'm excited to share insights from the initial stages of my project on Inverted Pendulum Stabilization Using a Reaction Wheel with Non-Linear Controller (Sliding Mode Control). This early-phase work dives into advanced control strategies for stabilizing an inverted pendulum system, a classic challenge in control theory and robotics. Project Highlights: 1. Inverted Pendulum System: A dynamic model requiring precise control to stay upright. 2. Reaction Wheel: Utilized to provide the necessary torque for stabilization by adjusting angular momentum. 3. Non-Linear Controller: Implemented a sliding mode control strategy, known for its robustness against disturbances and system uncertainties. Key Outcomes: - Enhanced Stability: Progressed towards effective stabilization of the inverted pendulum through advanced control mechanisms. - Robust Performance: The sliding mode controller showed promising results in handling non-linearities and external disturbances. This project is based on the foundational work presented in the attached paper, which guided our approach and methodology. Feel free to connect if you're interested in discussing control systems or have any questions! 🚀🔧

This 102 page book by Dr. Vikram A Munshi, provides a practical roadmap for those attempting to champion or lead transformation both within team and in organisations. Transposing his model at an enterprise level, Dr. Munshi provided an effective interplay of :Will (Instrinsic Motivation), Skill (Capabilities that drives transformation)and Drill (Work Methods) with a high degree of perspicacity. This book to me is a simple yet impactful way for business leaders and talent practitioners to lead and guide transformation for their ares of influence and control. A recommended read.

🔺🆂🆄🆄🅽🆃🅾 Replacements ♻ Another thing saved from the dumpster! When my Suunto T3 wrist watch bands broke, I saw it as an opportunity rather than a setback. Using TPU and my 3D printer, I designed and created custom replacement bands. This wasn't just about fixing a broken watch; it was about diving into a challenge and emerging with a practical solution. Each project like this not only solves a problem but also teaches me something new. You can download the parts for free here: https://lnkd.in/d84-R6AR I love being an engineer because it allows me to continuously learn and innovate. Whether it's designing replacement parts, improving existing designs, or creating something entirely new, I thrive on the process of problem-solving and discovery. If you're looking for a passionate engineer who brings creativity and dedication to every project, let's connect! I'm always eager to discuss new challenges and opportunities.
