lesson 2 digital data acquisition and data processingMathew John
Digital data acquisition and processing are important for nondestructive evaluation (NDE). Data acquisition is needed to obtain quantitative information from test specimens in complex field environments. Data analysis techniques like noise reduction, feature extraction, and multi-parameter discrimination can then be used to interpret the data. Proper data acquisition, digital signal processing algorithms, and discrimination methods now allow NDE procedures to be automated and problems previously considered unsolvable to be addressed.
The tuning of Microwave Circulators utilizing gyromagnetic materials requires the calibration of the biasing magneto-static field, which is mostly supplied by permanent magnets. The permanent magnets have to be tuned down from saturation to an appropriate magnetization stage by means of specialized magnetizing and tuning equipment. A tuning procedure suited for automated adjustment of the saturation level of permanent magnets is described, based on S-parameter measurements. Eigenvalues of the measured 3x3 S-matrices are used to determine a required setting on a computer controllable magnetizer. This will enable a quick and accurate automated tuning process.

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:
In the rapidly evolving landscape of technologies, XML continues to play a vital role in structuring, storing, and transporting data across diverse systems. The recent advancements in artificial intelligence (AI) present new methodologies for enhancing XML development workflows, introducing efficiency, automation, and intelligent capabilities. This presentation will outline the scope and perspective of utilizing AI in XML development. The potential benefits and the possible pitfalls will be highlighted, providing a balanced view of the subject.
We will explore the capabilities of AI in understanding XML markup languages and autonomously creating structured XML content. Additionally, we will examine the capacity of AI to enrich plain text with appropriate XML markup. Practical examples and methodological guidelines will be provided to elucidate how AI can be effectively prompted to interpret and generate accurate XML markup.
Further emphasis will be placed on the role of AI in developing XSLT, or schemas such as XSD and Schematron. We will address the techniques and strategies adopted to create prompts for generating code, explaining code, or refactoring the code, and the results achieved.
The discussion will extend to how AI can be used to transform XML content. In particular, the focus will be on the use of AI XPath extension functions in XSLT, Schematron, Schematron Quick Fixes, or for XML content refactoring.
The presentation aims to deliver a comprehensive overview of AI usage in XML development, providing attendees with the necessary knowledge to make informed decisions. Whether you’re at the early stages of adopting AI or considering integrating it in advanced XML development, this presentation will cover all levels of expertise.
By highlighting the potential advantages and challenges of integrating AI with XML development tools and languages, the presentation seeks to inspire thoughtful conversation around the future of XML development. We’ll not only delve into the technical aspects of AI-powered XML development but also discuss practical implications and possible future directions.

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.

3. Introduction
As high-performance computing (HPC) bends to the
needs of "big data" applications, speed remains essential
The programs are getting more and more complex and
time-consuming to develop. A few years ago, when an
HPC startup Edelman was involved in Interactive
Supercomputing .It was acquired by Microsoft and its
group set out to develop a programming language, julia.
4. Julia is a high-level, high-performance dynamic
programming language for technical computing, with
syntax that is familiar to users of other technical
computing environments.
It provides a sophisticated compiler, distributed parallel
execution, numerical accuracy.
Why Julia
5. The creators wanted a language that satisfies:
1.The speed of C.
2. With the dynamism of Ruby.
3. Mathematical notations like Matlab.
4. As usable for general programming as Python.
5.As easy for statistics as R.
7. All arguments are equally responsible to
determine a method.
In single dispatch the calls cat.run("fast")
and cat.run(5) would dispatch to the same
method and it is up to the method to do
different things with the different types of the
second parameter.
In Julia run(cat, "fast") and run(cat, 5)
dispatch to separate methods.
Multiple dispatch
8. Julia’s LLVM-based just-in-time (JIT) compiler
combined with the language’s design allow it to
approach and often match the performance of C
Julia’s ability to compile code that reads like
Python into machine code that performs like C
almost entirely derives from Julia’s ability to
specialize function definitions in this way.
High-Performance JIT Compiler
10. Foreign function interfaces to a number of
languages like C and Fortran, C++ (unfortunately
planned only for Julia 0.5), Python, R, Matlab.
This makes it relatively easy to use code in any of
these languages
Built-in package manager
11. To allow easy use of this existing code, Julia
makes it simple and efficient to call C and
Fortran functions.
The machine instructions generated by Julia’s
JIT are the same as a native C call would be, so
the resulting overhead is the same as calling a
library function from C code.
Call c functions directly
12. # julia
function mmult(A,B)
(M,N) = size(A);
C = zeros(M,M);
for i=1:M
for j=1:M
for k=1:M
C[i,j] += A[i,k]*B[k,j];
end
end
end
C;
end
// C
#define M 500
void mmult(double A[M][M],double
B[M][M],doubleC[M][M])
{
//double C[M][M];
int i,j,k;
for(i=0; i<M; i++)
for(j=0; j<M; j++){
C[i][j] = 0;
for(k=0; k<M; k++)
C[i][j] += A[i][k]*B[k][j];
}
}
Sample program on julia
14. Julia already possesses a mature package
ecosystem and can be used as a feature-complete
replacement for R or Python.
Julia’s compiler is so good that it will make any
piece of code fast – even bad code.
It's touted as a high-level language, which means
it's easier to learn. It's normally faster to write code
in a high-level language.
Advantages
15. Julia arrays are 1-indexed, which can really trip
you up sometimes when you're used to Python,
C/++, Java, etc.
Julia list comprehensions (currently) lack the
ability to use conditionals, unlike Python. One
can do this with for loops and if/else, though, as
normally done.
Julia dictionaries are hashed differently than
Python dictionaries, which can make them
slower in many cases.
Disadvantages
16. Conclusion
Julia is a flexible dynamic language, appropriate
for scientific and numerical computing
Julia combines the features of many other
programming languages like C, Matlab and Java
etc.
Existence of JIT Compiler in Julia increases the
performance of computuing.
