We live in the age of data. From global warming stats to customer behavior patterns, new technologies have made it easier to collect, store, access and analyze information. But our use of these technologies has also eroded our attention spans and fueled post-truth misunderstandings. To combat these trends, the question [...]

Being forced to work from home now, I launched into cleaning out stuff on my hard disk and dug into long unvisited folders.

There are many Sankey diagrams still sitting there. So, you might eventually see a higher posting frequency again over the next couple of weeks. At least something good…

Another sample Sankey diagram in German from the building sector. Swiss architectural firm Moosmann Bitterli has this on their website to showcase their services. Not sure what the unit of flow is, but definitely energy related.

Just a quick Friday afternoon post in order not to let this week slip past without a post. This is a sample from the latest e!Sankey demo version,

The Sankey diagram represents energy flows in a canning plant with heat being distributed to the various steps of the process. Recovery of energy (red-brown arrow) from two of the steps.

Some of the problems we work on as UX researchers are simple and are easily solved by getting users in front of our product. But other problems can be complex and it's hard to know how to start solving them. In situations like that, a simple 2x2 diagram can cut through the 'what ifs', the 'how abouts' and the edge cases and provide a simple way of looking at the problem. Here are 10 examples of 2x2 diagrams to simplify UX research discussions.

Earlier this year, Rolling Stone called Deerhunter, “one of the great guitar bands of the 21st century.” But that’s not the only music to come from the Georgia band. Moses Archuleta is co-founder and drummer for Deerhunter. He also has a solo side project called Moon Diagrams, which released a new album, titled Trappy Bats , in August. We invited Archuleta to add two songs to the Georgia Playlist. That’s our collection of songs written or performed by a Georgian. His picks? Athens band Pylon, and Atlanta native Playboi Carti.

Our world is becoming increasingly intelligent, interconnected, and instrumented, resulting in massive amounts of data being collected. This data is a treasure trove of information that can be mined to improve service, increase sales, determine risk, or make operations more efficient.

Analysis of such large amounts of data, often called analytics, is increasingly desired by governments and businesses alike.

Abstract:
In this paper, we study the persistent homology associated with topological crackle generated by distributions with an unbounded support. Persistent homology is a topological and algebraic structure that tracks the creation and destruction of topological cycles (generalizations of loops or holes) in different dimensions. Topological crackle is a term that refers to topological cycles generated by random points far away from the bulk of other points, when the support is unbounded. We establish weak convergence results for persistence diagrams – a point process representation for persistent homology, where each topological cycle is represented by its $({mathit{birth},mathit{death}})$ coordinates. In this work, we treat persistence diagrams as random closed sets, so that the resulting weak convergence is defined in terms of the Fell topology. Using this framework, we show that the limiting persistence diagrams can be divided into two parts. The first part is a deterministic limit containing a densely-growing number of persistence pairs with a shorter lifespan. The second part is a two-dimensional Poisson process, representing persistence pairs with a longer lifespan.

Water, water, everywhere, so let's all have a drink (or so we all learned as kids, right?), but it's definitely not as easy as that these days. In honor of World Water Day (which may or may not have been today), let's
