Nicely describe everything about super critical technology in thermal power plant.This slide is very useful for the freshers.Anybody can get the basic fundamental idea about super critical technology from this slide. In India now we have to think some new technology for power sources as sub critical power plants are less efficient and emit more pollutant to the environment and the alternative is the 'Super Critical Power Plant'.
How to Improve Steam Turbine Head Rate and Increase OutputMargaret Harrison
As the steam path degrades in mature steam turbines performance loss often occurs. Reducing heat rate while increasing output can have a significant impact on earning potential within the current market and today’s regulatory conditions. Improvements of 3% or more have been seen by users who have installed the full package of steam turbine seals in their units. EthosEnergy has been developing advanced turbine sealing technologies that improve efficiency and performance of steam turbines for over 30 years.

Cause and prevention for steam turbine blade scaling & fouling Prem Baboo
The paper intended to deposition of Wang scaling/deposition & corrosion on turbine blades. How to deposit these scales? Prevention and control the deposits. Major steam turbine problems causes and effects. Practical examples of our shut down experience of 40 ata & 100 ata steam turbines. Lab analysis detail report of wet steam cleaning and sand blasting cleaning of the blades.
A steam turbine is a prime mover in which the potential energy of the steam is transformed into kinetic energy and later in its turn is transformed into the mechanical energy of rotation of the turbine shaft
Description- This project was taken up to reduce the problem of Global warming due to the use of CFCs and HFCs refrigerants in Industries for spot cooling and for other purposes, as Vortex tube uses compressed air for cooling which is environment friendly and free of cost. Also the fabrication of Vortex Tube was done using CPVC material which is cheaper & lighter alternative to its other conventionally used metal counterparts. The minimum cooling effect of -1.9°C was attained and also the same was validated using CFD (Computational Fluid Dynamics) Analysis.
Advantages-
Vortex tube does not have any moving parts, makes it simple in construction.
It provides instant cold air in environmental chamber.
The cold air temperature can be easily adjusted with the help of valve.
The output temperature range and mass flow rate can be easily adjusted by changing nozzle bush or orifice bush.
No need of electricity if compressed air is available.
Not require any refrigerant or chemicals.
It is compact; light in weight makes it suitable for aviation application.
It can be worked in any position and at low cost applications.
It does not require any coolant.
It does not have spark or explosion hazard.
Improves tool life and improves finish.
Maintenance free unit.
The presentation discusses the various factors which affect the performance of Power Boilers including the quality of coal, airheater performance, air ingress etc.

Low charge ammonia vapour compression refrigeration system for residential ai...RAJESHKUMAR4616
Low-charge ammonia chillers provide a natural refrigerant option for the chiller market facing pressure to reduce the global warming impact of their systems. However, to make the most significant impact initially and for the life of the system, ammonia chillers must be able to deliver premium efficiency to assure the lowest indirect impact to the environment. Ammonia’s availability is not at risk of becoming scarce like hydrofluorocarbon (HFC) synthetic refrigerants; however, energy codes are always becoming more stringent and the most advantageous systems will stand the test of time from a chemical perspective and from a performance perspective.
Ammonia chillers with small amount of refrigerant have afforded the benefits of industrial quality and efficiency with the ability for deployment just like commercial packaged systems. However, packaged ammonia systems maintain some key differences relative to commercial HFC packages that are important to understand because they bring added value, but also additional capital cost. It is therefore important to consider the total cost of ownership to understand the business impact fully.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
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.

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).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

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.
