Unguided (Wireless) Media network communication .pptxamare63
Collaborating with suppliers can help improve inventory management through better communication, information sharing, and coordinated planning. This can lead to reduced lead times, improved quality, and lower costs.
Radio propagation is the way radio waves travel or propagate when they are transmitted from one point to another and affected by the medium in which they travel and in particular the way they propagate around the Earth in various parts of the atmosphere.
Outline of Presentation :
Modes of propagation, Ground Wave Propagation,
Structure of troposphere and ionosphere,
Characteristic of Ionospheric layers,
Sky wave propagation, Definitions for Virtual height,
Maximum Usable Frequency (MUF) and Skip distance,
Optimum Working Frequency (OWF), Fading,

Describe polarization and why it is important to WLANs.
Solution
Polarization, likewise called wave polarization, is a declaration of the introduction of the lines of
electric flux in an electromagnetic field ( EM field ). Polarization can be consistent - that is,
existing in a specific introduction at all circumstances, or it can turn with each wave cycle.
Polarization is essential in remote correspondences frameworks. The physical introduction of a
remote reception apparatus relates to the polarization of the radio waves got or transmitted by
that recieving wire. In this way, a vertical reception apparatus gets and transmits vertically
captivated waves, and an even radio wire gets or emanates on a level plane spellbound waves.
The best short-run correspondences is acquired when the transmitting and accepting (source and
goal) reception apparatuses have a similar polarization. The slightest proficient short-run
interchanges for the most part happens when the two reception apparatuses are at right edges (for
instance, one even and one vertical). Over long separations, the environment can bring about the
polarization of a radio wave to change, so the refinement amongst flat and vertical turns out to be
less noteworthy.
Some remote radio wires transmit and get EM waves whose polarization turns 360 degrees with
each total wave cycle. This kind of polarization, called curved or roundabout polarization, can be
either clockwise or counterclockwise. The best interchanges results are gotten when the
transmitting and getting reception apparatuses have a similar feeling of polarization (both
clockwise or both counterclockwise). The most noticeably bad correspondences for the most part
happens when the two radio wires emanate and get in the inverse sense (one clockwise and the
other counterclockwise).
Polarization influences the proliferation of EM fields at infrared ( IR ), noticeable, bright ( UV ),
and even X-beam wavelength s. In conventional noticeable light, there are various wave parts
aimlessly polarization points. At the point when such light is gone through an uncommon
channel, the channel hinders all light aside from that having a specific polarization. At the point
when two polarizing channels are put so a beam of light goes through them both, the measure of
light transmitted relies on upon the edge of the polarizing channels regarding each other. The
most light is transmitted when the two channels are arranged so they spellbind light in a similar
bearing. The slightest light is transmitted when the channels are arranged at right points to each
other.One of the minimum comprehended properties of a remote flag is its polarization,
particularly in the event that you are introducing a considerable measure of WiFi Antennas in
one area, as on a tower. Polarization is dictated by the way a radio wire is mounted, and can
normally just be either level or vertical. This is imperative, particularly in indicate point remote
correspondence, in light of .

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).

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.
