Testing a Computed Tomography Imaging Spectrometer for Earth Observations on the HEIMDAL Stratospheric Balloon Mission
Stratospheric High Altitude Balloons (HABs) have great potential as a remote sensing platform for Earth Observations that complements orbiting satellites and low flying drones. At altitudes between 20-35 kms, HABs operate significantly closer to ground than orbiting satellites, but significantly higher than most drones. HABs therefore offer a unique potential to deliver high spatial resolution imaging with large area coverage. Another two imaging parameters that are important for Earth Observat…

A LiDAR-Driven Fallback Longitudinal Controller for Safer Following in Sudden Braking Scenarios
Adaptive Cruise Control has seen significant advancements, with Collaborative Adaptive Cruise Control leveraging Vehicle-to-Vehicle communication to enhance coordination and stability. However, the reliance on stable communication channels limits its reliability. Research on reducing information dependencies in Adaptive Cruise Control systems has remained limited, despite its critical role in mitigating collision risks during sudden braking scenarios. This study proposes a novel fallback longit…

Improving After-sales Service: Deep Reinforcement Learning for Dynamic Time Slot Assignment with Commitments and Customer Preferences
Problem definition: For original equipment manufacturers (OEMs), high-tech maintenance is a strategic component in after-sales services, involving close coordination between customers and service engineers. Each customer suggests several time slots for their maintenance task, from which the OEM must select one. This decision needs to be made promptly to support customers' planning. At the end of each day, routes for service engineers are planned to fulfill the tasks scheduled for the following …

1/2 Thanks to @… for this interesting article. It speaks to me. :)
I’ve been weather blogging @… since 2005. It is interesting how it has changed, and how I have changed.
My website used to be just data from the (expensive) station I bought when I moved back to Port Alberni. It was a hobby and a side project to practice web/coding skills I use at work. My focus was on creating useful data for people that was more local/relevant than the official EC station outside of the city.
Then I put up a webcam and learned how to make timelapses. This got the attention of local media… because pictures. :)
Then I added a blog and started to write about the weather almost daily. This was before Facebook. There was a popular local online forum where I would post things. The media would also follow my website and they started to call me when there was extreme weather (usually very hot or very wet/stormy).
Then Facebook started to get big and I made a page that eventually had a few thousand followers. I would blog often. Lots of traffic from Facebook… this was 2010 and on. I blogged about climate and weather pretty equally.
Like anyone in Port Alberni, I was/am obsessed with the Martin Mars and got wrapped up in that issue along with others which combined with the weather following probably gave me just enough exposure to have me elected as a councillor in 2014.
I continued through that 4 years, blogging often in addition to councillor duties and work, heavily on facebook, then it all went sideways on my own poor judgement (go ahead and google it, it’s ok :)) and I was not reelected, but Facebook by 2018 had also changed. Cambridge Analytica, etc.

Good Morning #Canada
In August 1998, the Supreme Court of Canada ruled that Quebec could not legally secede from Canada unilaterally. The court's decision affirmed that any secession would require a constitutional amendment negotiated with the federal government and other provinces. This ruling stemmed from a reference case initiated by the federal government following a close referendum on Quebec sovereignty in 1995. Although Quebec was represented at the Supreme Supreme Court hearing, they did not participate in presenting arguments. They essentially ignored the ruling and planned a future referendum, which never happened.
This ruling established an important precedent that Alberta separatists should pay attention to. But details such as this ruling, aboriginal rights, or common sense seem to escape their attention spans.

Atomically thin silver films for enhanced nanoscale nonlinear optics
The inherently weak nonlinear optical response of bulk materials remains a fundamental limitation in advancing photonic technologies. Nanophotonics addresses this challenge by tailoring the size and morphology of nanostructures to manipulate the optical near field, thus modulating the nonlinear response. Here, we explore a complementary strategy based on engineering the electronic band structure in the mesoscopic regime to enhance optical nonlinearities. Specifically, we demonstrate an increase…

Structural and Electrocatalytic Properties of La-Co-Ni Oxide Thin Films
La-Co-Ni oxides were fabricated in the form of thin-film materials libraries by combinatorial reactive co-sputtering and analyzed for structural and functional properties over large compositional ranges: normalized to the metals of the film they span about 0 - 70 at.-% for Co, 18 - 81 at.-% for La and 11 - 25 at.-% for Ni. Composition-dependent phase analysis shows formation of three areas with different phase constitutions in dependance of Co-content: In the La-rich region with low Co content,…

Immersions and Albertson's conjecture
A graph is said to contain $K_k$ (a clique of size $k$) as a weak immersion if it has $k$ vertices, pairwise connected by edge-disjoint paths. In 1989, Lescure and Meyniel made the following conjecture related to Hadwiger's conjecture: Every graph of chromatic number $k$ contains $K_k$ as a weak immersion. We prove this conjecture for graphs with at most $(1.64-o(1))k$ vertices. As an application, we make some progress on Albertson's conjecture, according to which every graph $G$ with chromatic…
