In 2006 the European Union issued a Directive on the Restriction of Hazardous Substances (RoHS) which among other materials banned the use of lead in electronics. The Aerospace and Defense (A&D) industry in the US designs and manufactures products that carry more than three billion passengers worldwide on any given day as well as systems which are vital to our national security. In order to transition to lead-free electronics, the A&D industry demands careful analysis and research into the performance, reliability and safety of these materials in order to maintain public safety and assure our war-fighters’ mission is successful and safe. In this effort, the College of Engineering at Tuskegee University and the Boeing Company has teamed to understand some of the knowledge gaps that surround this new technology. Students at Tuskegee are undertaking an effort to understand the best use of conformal coatings to mitigate the risks these tin protrusions can cause in an electronic circuit. Also, Tuskegee is studying the effects tin whiskers may have on the ability of conformal coatings to protect Circuit Boards from corrosion.

TESTING OF COMPOSITE ON DROP-WEIGHT IMPACT TESTING AND DAMAGE IDENTIFICATION ...AM Publications
In recent years the use of composite materials in structural components has become increasingly common in a wide range of engineering applications. Composite materials offer numerous advantages over more conventional materials because of their superior specific properties, but a serious obstacle to a more widespread use of these materials is their high sensitivity to localized impact loading. This paper presents an experimental study to assess the impact response of drop weight impact tests on fiber reinforced polymer composites with deferent load and damage identification of composite using Non-destructive testing techniques ultrasonic testing (UT) C scan. In the study includes checking the strength of the specimen, plotting of graphs between the height and the impact energy obtained and tabulating the results after conducting the various functional tests.
Spacecraft structures are designed to support the maximum quasi-static loads they will be subjected to during their lifetime. It is a normal practice in these space projects to perform a test to qualify this structural design. The standard testing approach is achieved by subjecting the structure or satellite to those loads using a wiffle tree, a centrifuge machine or an electrodynamic shaker. Each one of these testing options has its own weak points: wiffle tree is not able to test actual flight spacecrafts; centrifuge tests require a very expensive facility and can only be used to test low mass spacecrafts and the current electrodynamic shaker tests have maximum mass and minimum frequency limitations. Because of these limitations, a simple and efficient alternative that can fulfill almost any mass, frequency and load requirement is herein proposed. This non-conventional approach is based in the simplest way to generate a quasi-static acceleration wave using the spring-mass-damper concept. Due to its simplicity, this system does not require high technology components helping to obtain a very low cost quasi-static testing machine. Then, the main objective of this presentation is to show the key characteristics of this solution including a detailed table comparing its performance versus the standard ones, finally it must be highlighted that in spite the design to be presented is able to test spacecrafts from 100 to 4000 kg this concept has no limitations for testing lighter or heavier satellites.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
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:
