Propagation Effects for Radar&Comm SystemsJim Jenkins
This three-day course examines the atmospheric effects that influence the propagation characteristics of radar and communication signals at microwave and millimeter frequencies for both earth and earth-satellite scenarios. These include propagation in standard, ducting, and subrefractive atmospheres, attenuation due to the gaseous atmosphere, precipitation, and ionospheric effects. Propagation estimation techniques are given such as the Tropospheric Electromagnetic Parabolic Equation Routine (TEMPER) and Radio Physical Optics (RPO). Formulations for calculating attenuation due to the gaseous atmosphere and precipitation for terrestrial and earth-satellite scenarios employing International Telecommunication Union (ITU) models are reviewed. Case studies are presented from experimental line-of-sight, over-the-horizon, and earth-satellite communication systems. Example problems, calculation methods, and formulations are presented throughout the course for purpose of providing practical estimation tools.

What are electromagnetic waves?
Solution
We are encompassed by waves we can see and listen, from sea waves to sound waves. A wave
demonstrates the exchange of vitality, from the wind that begins a sea wave to the sound that
travels through the air to your ear drum. Waves that go through a physical protest or medium are
called mechanical waves. Dissimilar to mechanical waves, electromagnetic waves needn\'t
bother with a medium to travel or spread. Electric and attractive fields both deliver vibrations
and, together, the two sorts of vitality make electromagnetic waves.
Waves take distinctive shapes, yet electromagnetic waves all have a snake-like shape, which
makes them transverse waves. Transverse waves are measured by their tallness, or sufficiency,
and by their wavelength, or the separation between the most astounding purpose of one wave, the
peak, to the peak of the following wave. The most reduced purpose of a wave is known as a
trough. Trough to trough can be measured, as well. While dissecting an electromagnetic wave,
both the plentifulness and separation between waves is measured.
One entire wave, from peak to peak, or trough to trough, is known as a cycle. The quantity of
cycles that happen every second is the wave\'s recurrence. Out of appreciation for Heinrich
Hertz, we measure recurrence in hertz or Hz.
Electromagnetic waves will be waves which can go through the vacuum of space. Mechanical
waves, not at all like electromagnetic waves, require the nearness of a material medium keeping
in mind the end goal to transport their vitality starting with one area then onto the next. Sound
waves are cases of mechanical waves while light waves are cases of electromagnetic waves.
Electromagnetic waves are made by the vibration of an electric charge. This vibration makes a
wave which has both an electric and an attractive segment. An electromagnetic wave transports
its vitality through a vacuum at a speed of 3.00 x 108 m/s (a speed esteem ordinarily spoke to by
the image c). The proliferation of an electromagnetic wave through a material medium happens
at a net speed which is under 3.00 x 108 m/s. This is portrayed in the liveliness underneath.
The instrument of vitality transport through a medium includes the assimilation and reemission
of the wave vitality by the molecules of the material. At the point when an electromagnetic wave
encroaches upon the molecules of a material, the vitality of that wave is retained. The retention
of vitality causes the electrons inside the iotas to experience vibrations. After a brief time of
vibrational movement, the vibrating electrons make another electromagnetic wave with an
indistinguishable recurrence from the main electromagnetic wave. While these vibrations happen
for just a brief timeframe, they defer the movement of the wave through the medium. Once the
vitality of the electromagnetic wave is reemitted by a molecule, it goes through a little locale of
space between particles. When it achieves the foll.

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).

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:

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).
