Determination of suspended pm in atomosphereECRD2015
This document provides details on the high volume method for determining suspended particulate matter concentrations in ambient air. Key points:
- Air is drawn through a size-selective inlet and filter at a rate of 1132 L/min. Particulate matter with aerodynamic diameters less than the inlet cut-point are collected on the filter.
- The mass of particulate matter is determined by the difference in pre-and post-sampling filter weights. Concentration is calculated by dividing the weight gain by the air volume sampled.
- The method is applicable for measuring suspended particulate matter concentrations ranging from approximately 3.5 to 1000 μg/m3, depending on factors like sample duration and aerosol composition.

Ammonia Slip Emission Control in DeNOx processes AndreaTancredi4
This document discusses controlling ammonia (NH3) slip in combustion processes. It provides an overview of technologies for reducing oxides of nitrogen (NOx) emissions from combustion furnaces, including low NOx burners, over fire air, reburn, and selective catalytic reduction (SCR). SCR can reduce NOx by 80-90% but requires higher upfront costs while selective non-catalytic reduction (SNCR) reduces NOx by 40-60% with lower operation costs. Laser-based gas analyzers provide benefits for measuring NH3 slip including fast response, no sampling system, ability to handle high dust environments, and low maintenance needs.
If you want to analyze different gases including SO2, CO2,CO,NO, O2 and HC, it would be best to use CEMS. This is the best way to go for getting right kind of things.

Understanding what airborne dust is, its potential health effects and how to manage dust in all areas of the workplace is fundamental to ensure that the respiratory health of your workforce is protected.
Generating potentially harmful levels of respirable airborne dust is not confined to production-based tasks within an operation. Engineering and maintenance tasks also have the potential to expose tradesmen and operators to respirable dust that can cause lung disease. Many of these tasks are also often conducted without the need for respiratory protection being taken into consideration.
Occupational dust disease is 100% preventable, and the key to workers making smart choices about their health is education.
This presentation is a generic version of the Airborne Dust Awareness sessions that have been rolled out to thousands of mineworkers in the NSW coal industry recently and has resulted in positive behavioural change in and around the workplace.
As industry leaders, we all need to understand the risks before we can identify them, then eliminate or control them.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

Digital Banking in the Cloud: How Citizens Bank Unlocked Their MainframePrecisely
Inconsistent user experience and siloed data, high costs, and changing customer expectations – Citizens Bank was experiencing these challenges while it was attempting to deliver a superior digital banking experience for its clients. Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.
Compared to other technology sectors (for instance IT), air quality monitoring is a very “conservative” market, and the take-up of new technology often very slow, even if there are clear cost-benefit advantages for doing things differently.
This presentation will look at just a few innovative ideas and alternative technologies and I hope it will provide a greater insight for you.
ChemiluminescentNOx analysers have been around for 30+ years. Although the electronics have changed (there were no microprocessors in analysers just 20 years ago), the actual measurement and detection systems within them have hardly changed at all. Reaction cell, ozone generator, moly-con etc.Chemiluminescence is still regarded as the “Gold Standard” for ambient NOx monitoring world-wide and is in fact an ISO reference method.They will be with us for a long time to come although there are other thoroughly proven and well established techniques like DOAS which we will come back to.In the 20 years I have been at ET, I’m yet to see any manufacturer in the world manage to make a NOx analyser much smaller. Lift the lid on one and you will see why. They are jam packed with modules, all of which necessary for the chemiluninecence reaction to take place.
Although at first glance this may not look any different than other roadside enclosures, look again. It is very “skinny”. Only 300mm deep in fact. This makes for a very small, unobtrusive footprint. They can be far easier to site than more common enclosures.
How do we do it? Simple, just mount the analyser vertically rather the typical horizontal approach. The analyser performs just as well and means we can save lots of space! We leave enough in there though for gas cylinders, regulators, pumps, modems, etc. Just a bit of clever packaging really!
When you would like to measure NOx and maybe one or two other pollutants, but don’t need the precision and overall accuracy of “reference method analysers” such as chemiluminescentNOx, then the TrafficBOx could be of interest?There have been tremendous improvements in gas sensor technology over the last decade and sensors such as metal-oxide semiconductors can now measure compounds such as NO2 down to roughly the same levels of detection as chemiluminescence (around 1 ppb). With a range of up to 500 ppb they lend themselves well to air quality monitoring. True the sensors need replacing every couple of years and don’t offer the repeatability and precision compared to say chemiluminescence, but they are excellent for “indicative” monitoring and far more useful than diffusion tubes as you can see what is happening minute by minute, rather than waiting a month or two for lab analysis and then just monthly mean.We can add PM10 with an optical laser backscatter system. Again, not perfect, but useful for indicative purposes.Other sensors can be added for gases such as O3, CO and NHS.All wrapped up in a neat package with data logging, communications and software for analysis/data export.

Measure up to 6 x gases + dust, or customise choosing whichever sensors you need. PM10 and NO2 an obvious favourite!Housed in a weatherproof case which can be mounted on a wall or lamppost etc.
Opsis is an open-path, non-contact, optical gas monitoring technology based on differential optical absorption spectroscopy.Three main parts of the system, an emitter (light source), a receiver and a computerised multi-gas spectrometer.No pumps, sample lines, pneumatics, filters and it requires little or no LSO involvement and calibration only once every 6 months. Perfect!
One of Swansea City Council’s large Groundhog AURN type stations.
Picture shows DOAS analyser, and emitter/receiver set.
System in operation in Swansea measuring NO NO2 O3 BTEX over a 600m open-path alongside main arterial road.
OPSIS is MCERTS approved for NO2 SO2 O3 and Benzene. UK users include Swansea City, Sandwell MBC, Walsall MBC, Corus and several industrial plants.
Although the TEOM and TEOM/FDMS is very widely used in the UK, there ARE alternatives!We all know now that the original TEOM unit did not meet the EU equivalency testing criteria and the FDMS was introduced partly to overcome these original under-reading measurement problems.Take a look at the BAM1020.BAM stands for beta-attenuation mass monitoring. BAM’s or beta-gauges, have been around for 25+ years.Well before the TEOM, and now, well after it!Well proven technology, well tested (US-EPA, TUV, CARB etc) and more importantly “shown to meet equivalence criteria set out in the UK equivalence programme for monitoring of particulate matter” for PM10. Just like the TEOM/FDMS.The BAM1020 PM2.5 system has also been tested by BV/TUV for CEN equivalence and will be certified during summer 2010.
Due to the design of the beta-attenuation measurement principle, the BAM has a base resolution of 60 minutes. In other words, it records hourly averages of PM10 or PM2.5. For many urban applications this is fine as the UK/EU reporting frequency for PM10 is a 24 hour average.For those wanting a faster resolution, there is a real-time module (RTM) which is a simple bolt on to the BAM inlet. This is a laser back-scatter unit and enables 1, 5, 15, 30 minute measurement resolution as well as the standard BAM hourly average.
