emission measuring equipment for CO2,CO & HC
The Orsat gas analyzer uses a series of absorption bulbs containing different solutions to measure the concentrations of CO2, O2, CO, and nitrogen in flue gas samples. The flue gas is first drawn into a water-filled burette and its initial volume is recorded. It is then passed through different absorption bulbs where specific gases are absorbed. The volume of gas remaining after each absorption step provides the volume of the gas absorbed, allowing calculation of its concentration in the original sample.

Fire early warning system is an independent subsystem of automatic fire alarm system. It mainly includes combustible gas detection and alarm system and electrical fire monitoring system.
Combustible gas detection and alarm system is mainly used in the use, production of combustible gas or combustible steam places.
division of fire alarm areas
Alarm area is a unit that divides the warning range of automatic fire alarm system according to fire zone or floor. An alarm area includes a plurality of detection areas.
The purpose of dividing the alarm area is to determine the location of the alarm and fire. At the same time, it is convenient to solve the problem of fire control system linkage design.
The alarm area should be divided according to the fire zone or floor. You can also divide several adjacent fire zones or floors that need to be simultaneously linked with fire fighting equipment into an alarm area in case of fire.
addressable fire alarm bus short circuit isolator
Bus short circuit isolator is simply called bus isolator.
It is necessary to install bus short circuit isolator in bus automatic fire alarm system. When a bus fails, the bus isolator automatically separates the faulty bus part from the whole system to ensure the normal operation of the rest of the system.
At the same time, the fire alarm controller indicates the part number of the isolated parts, which is convenient for maintenance.
When the fault is rectified, the bus isolator automatically reintegrates the isolated part into the system.
fire manual call and hydrant button
Manual fire alarm button is a manual fire alarm device.
After the alarm button is pressed, the alarm signal is sent to the fire alarm controller through the bus loop.
The controller displays the position, code and annotation information of the alarm button, and sends out sound and light alarm signal.
The alarm button should be set with a red start confirmation light. After pressing the alarm button, the start confirmation light should be lit and kept until the alarm state is reset.
addressable fire alarm system input module
The input module, also known as the monitoring module, is used to receive the action signal of the monitored device and can be connected to the monitored device with normally open or normally closed signal output.
The input module adds an address code to the action signal of the monitored device, and transmits it to the fire alarm controller through the signal bus to issue an alarm signal or linkage trigger signal.
The input module can be equipped with all kinds of equipment that need feedback signals on the site, such as water flow indicator, pressure switch, signal valve control cabinet, and all kinds of external linkage equipment that can provide switch signals.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.
What is an RPA CoE? Session 2 – CoE Roles
In this session, we will review the players involved in the CoE and how each role impacts opportunities.
Topics covered:
• What roles are essential?
• What place in the automation journey does each role play?
Speaker:
Chris Bolin, Senior Intelligent Automation Architect Anika Systems
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

Containers & AI - Beauty and the Beast!?!
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.
Keywords: AI, Containeres, Kubernetes, Cloud Native

carbon monoxide detection system
- 1. According to the code, carbon monoxide detectors should be installed in places where carbon monoxide leakage is possible. For the choice of carbon monoxide detector, you may have the following questions: Carbon monoxide is both a combustible gas and a toxic gas，should I choose a carbon monoxide detector or a combustible gas detector? According to the requirements of petrochemical combustible gas and toxic gas detection alarm design code, only toxic gas detectors should be installed. Therefore, carbon monoxide toxic gas detector should be selected when selecting detectors in places where carbon monoxide leakage may exist. In addition, the detection of carbon monoxide leakage detector and the detection of fire carbon monoxide fire detector is a completely different concept. Carbon monoxide fire detector is a special kind of fire detector. Most fires will produce carbon monoxide gas, and the characteristics of carbon monoxide are more obvious for early fires and smoldering fires with insufficient combustion. Carbon monoxide fire detector is an effective fire detection method by detecting the carbon monoxide produced by the fire. The carbon monoxide toxic gas detector used to detect carbon monoxide leakage can be connected to the combustible gas detection and alarm system.
- 2. Carbon monoxide fire detectors used to detect fires should be connected to automatic fire alarm systems. From https://www.vedardsecurity.com/carbon-monoxide-detection-ezp-33 By Vedard Security Alarm Technology
