So, what exactly are AI companion apps, and how do they work? Basically, they’re platforms that let you engage in conversations with virtual characters, simulate scenarios, and even write stories. The apps fall into a couple of different sub-categories: those…
An AI chatbot girlfriend goes a little beyond the scope of a traditional chatbot. These apps do more than answer questions; they can carry small talk, retain information, facilitate a specific fantasy or roleplay, and answer in an informal or…
These days, AI is a common occurrence that can be useful when drafting an email, figuring out a meal plan, studying, or just having a question answered by an LLM. Some tools are used for entertainment, whether it be roleplay…
Validation in urban dispersion is never easy. In such cases, there is evidence to consider: fluctuating meteorology, dynamic traffic emissions, urban complexity, uncertainty and spatial heterogeneity in both emissions and concentrations. AI can aid this process but does not eliminate…
Air pollution is hardest to understand in street canyons. Roads have buildings on both sides and emit right next to where people are standing. In these relatively narrow areas, air flow can get funnelled, held, slowed, reversed, or trapped. Consequently,…
Short-term peaks are challenging to forecast given how quickly they can arise from rapidly changing local conditions. It could be just a few minutes’ congestion, the wind shifting, a line of vehicles stopping at a junction, or a lack of…
The occurrence of pollution hotspots is seldom haphazard; instead, it arises when a confluence of factors — such as emissions intensity, street canyon geometry, wind characteristics, and exposure levels — combine in such a manner that they generate a recurring…
Urban dispersion models provide a way of calculating how pollutants travel through street and junction networks, building canyons, and across the wider urban area. They help complete missing measurement records, explore scenarios, and underpin decisions regarding monitoring network design, planning…
