This document discusses tribology and wear-out of mechanisms. It outlines the methodology used by Verhaert Space, which includes selecting between wet and dry lubrication, avoiding poor design, analyzing contact loads and stresses, assessing wear aspects, and making decisions on lubrication and materials selection. The document then discusses wet versus dry lubrication pros and cons, design considerations to avoid wear, analysis aspects to cover, and common myths regarding tribology and wear to assess wear mechanisms.
Recrystallization is the process in which deformed grains of the crystal structure are replaced by a new set of stress-free grains that nucleate and grow until all the original grains have been consumed. The process is accomplished by heating the material to temperatures above that of crystallization.

Impact Testing of metals is performed to determine the impact resistance or toughness of materials by calculating the amount of energy absorbed during fracture. The impact test is performed at various temperatures to uncover any effects on impact energy. These services provide test results that can be very useful in assessing the suitability of a material for a specific application and in predicting its expected service life.
This book offers fundamentals and a comprehensive overview of tribology in sever conditions. It addresses a comprehensive coverage of classical tribology of solid contacts, friction mechanics, wear mechanisms and lubrication technologies. Characteristics of tribological systems operating under extreme conditions involving extraordinary loads, temperatures, speeds, and vacuum are discussed. Surface coating, surface treatment, and lubrication are argued considering the cutting-edge researches. In addition, tribology of automotive components is presented, as are tribological applications in many practical situations. The tribology of polymer composites, MEMS and NEMS are explored. A basic understanding of failure in tribological systems is covered. Various test methods used in evaluating wear are reviewed. Diverse techniques applied in predicting wear behavior by mathematical models, FE modeling and ANN approach are discussed.
Fatigue is important as it is the largest cause of failure in metals, estimated to comprise approximately 90% of all metallic failures; polymers and ceramics are also susceptible to this type of failure.

To explain the tremendous evolution in ICT the last decades, one typically refers to the Law of Moore. Today we’re facing with new languages and methodologies popping up like buzz words. Understanding the evolution of programming and cornerstone concepts will help you to position and value future programming languages and trends.
Although GPS developments started in 1967, it’s only in the early 70’s that NASA launched its first Earth Observation satellite. Contemporary technologies like satellite navigation and remote sensing are key in our daily life. Still, we ain’t seen nothing yet. Explore the potential of these technologies in your future products or services, and find a way to get things done.
Based on demonstrations and cases you’ll explore the future impact on new interface technologies like gesture, augmented and virtual reality. Douglas Engelbart developed the computer mouse in the ’60s. It was the first in a list of human interface technologies that revolutionized the way we interact with ICT. What’s the next big thing?
At the end of the ’60s, the first research programs started on humanoid robots. Although this technology inspired many of us, it’s only now that we see first applications arise. What’s the status of the robotics technology? How is it impacted by other technologies like AI, RF and energy storage? Let’s discuss the evolution and potential for your business based on recent projects and technologies available at our partners and alumni start-ups.
Let’s discuss the boundary conditions to innovate successfully based on some cases in Flanders and the Netherlands. Most governments are taking about half of their gross national product for their account. They can be better off by being open to innovation in the public purchase process and act as a launching customer for their industry and start-ups.
What’s the impact of public moonshot projects on innovation if they’re set up the right way? Armstrong saw his first footstep on the moon as one small step for man, one giant leap for mankind. And he was right.
The human aspect in driving innovation is not to be underestimated. Driving innovation is done by implementing the necessary tools and structures. However driving desired behavior on individual and team level is at least equally important. Möbius will share insights in how to build an innovation and continuous improvement culture.
The key concept in any start-up? The freedom to experiment as basis for accelerated learning. Or like Pink Floyd sang in the 70’s: “We don’t need no education.” Is your FabLab ready for it?
How do you set up your venture and accelerate growth? Start-ups are in a fundamental different position than corporates. As a consequence they play a different ball game. What can the start-up culture learn from the ’60s?
What are the differences between popular innovation project management methodologies? Why does project management often fail? Learn how risk assessment should define your methodology in order to become a real innovation factory. The waterfall methodology has been promoted for years as the best practice for IR&D management. These days agile and scrum are increasingly popular as alternative. Hater or believer? Good or bad? Get guided through our body of knowledge as published in the Inspire Toolbox.
Project management in innovation can only be successful if it’s driven by a robust methodology integrating a clear quality assurance concept. What can trendy methodologies learn from the house of quality?
50 years ago, innovation centers like Xerox or Philips’ Natlab set the benchmark with their methodologies on organizing innovation. Today, innovation is influenced by rapid-moving triggers and companies have to organize accordingly. Discover current best practices on organizing your innovation ecosystem.
How do you reinvent a mature business with the right cocktail of user insights and technologies? The message is clear: choose for differentiation or servitization, or loose.
AI has an inevitable impact on your next generation products and services. Things evolved relatively slow since the first AI experiments in the ’60s. Today, AI is accelerating as no other technology has done before. How will the 4th wave of Artificial Intelligence transform your future business?
Discover the newest insights in understanding value drivers and their impact on new products and services. From technology improvement towards platform economy with the value pyramid. How to use new design skills and service design to create experience economy?
The adoption of innovative IoT technology in smart cities seems to go slower than the utopian predictions of the last decade. This might be because the traditional business-to-government model is no longer sufficient to bear the investment cost and get these systems operational. Multi-sided business models can offer
a possible solution, but require a different approach from governments as well as suppliers, as illustrated by recent Verhaert cases.
AI can be weaved together with space technologies to provide exciting new solutions to a wide array of industries. Get a glimpse of how space data can enhance businesses, and how ESA Space Solutions Belgium can offer you the tools and funding to develop your ideas.
New space in the Belgian and European start-up technology ecosystem. Presentation at the launch event of ESA Space Solutions Belgium on Wednesday the 7th of November in Brussels.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
