burning condition recognition of rotary kiln based on spatiotemporal features of flame video - sciencedirect

We develop an effective model based on spatiotemporal features of flame clip for the recognition of burning condition.The unsteady state condition of rotary kiln is first studied in this paper, and the proposed method achieves high recognition accuracy for it.We propose two computationally simple and effective 3D dynamic texture and structure descriptors, 3DBLBP and HOPC-TOP, to characterize dynamic texture and structure of flame.

In the coal-fire industry, recognition of burning condition is vital for combustion control and optimization as it can provide early warning of abnormal conditions in the combustion system. We propose an effective model based on spatiotemporal features extracted from flame video for burning condition recognition especially for unsteady state condition. This model extracts features from both the spatial and temporal dimensions based on multiple adjacent frames to capture the appearance and motion information of the flame. Two new three-dimensional (3D) descriptors are developed to characterize the dynamic characteristics of the flame video stream. A computationally simple and fast dynamic texture descriptor, 3DBLBP, is designed to extract flame dynamic texture and motion from three adjacent frames of a video block, and a dynamic structure descriptor, HOPC-TOP is developed by extracting 3D phase congruency information of video clip from three orthogonal planes to capture structure and motion characterizes of flame. The two descriptors are combined to extract spatiotemporal features from flame clip for burning condition recognition. Experiment results show the proposed framework can achieve a high recognition accuracy in the real-world data, thus verifying the effectiveness of our proposed framework for the recognition of burning conditions in a rotary kiln.

dark souls: 10 things you didn't know about the kiln of the first flame

dark souls: 10 things you didn't know about the kiln of the first flame

In a desperate effort to prolong his failing age of light, Lord Gwyn sacrificed himself to keep the embers of the First Flame alive. Unfortunately, to keep the First Flame burning, Gwyn had to rely on a powerful chosen undead to take his place in the Kiln of the First Flame.

The final area of the original Dark Souls, the Kiln of the First Flame is a place of great mystery. Very little is known about it, but we're here to shed a light on this perplexing place.

Though some Dark Souls players live for the thrill of PvP encounters, certain builds make getting invaded a major nuisance, and, unfortunately, the Kiln of the First Flame is one of the most active PvP environments in the game. Restoring your humanity here means that you'll almost certainly come across a high-level enemy player, and that can be a real burden for those simply questing to return to Gwyn's boss room.

Additionally, those hoping to summon others for the final boss encounter are at a disadvantage, as getting invaded in the time it takes to return to the fog gate feels more likely than not.

The Kiln of the First Flame is relatively free of enemies, though there are five Black Knights prowling the premises. This makes sense, as, according to the lore, they served as Gwyn's servants during the war against the dragons, and again during the effort to seal spawn of the Bed of Chaos in Lost Izalith.

Interestingly, each of the Black Knights in the Kiln area wields a different weapon, from swords, greatswords, axes, etc. Fort hose hoping to collect all of the Black Knight weapons before beginning new game plus, look no further!

Those who paid close attention to the introductory cutscene will know that the four LordsGwyn, Nito, The Witch of Izalith, and The Furtive Pygmygained their powers when the discovered four special Lord Souls within the First Flame.

Though it's simply speculation from the community, some believe that the Kiln of the First Flame was built on the ground where these souls were first discovered. There's little to prove or disprove this theory, as we don't have a solid idea of where the Kiln actually is, though it can be an interesting detail for fans head-canon.

Fan-favorite NPC Solaire of Astora can actually be summoned to help in the fight against Gwyn, though doing this requires that his questline be finished, something most players aren't likely to manage without a walkthrough.

Typically, Solaire is found in Lost Izalith, having turned hostile thanks to a sunlight maggot. This can be avoided if the player joins the Daughter of Chaos covenant, donates 30 humanity to Quaalag's sister in the Demon Ruins, and then opens the door to the Lost Izalith bridge and kills every sunlight maggot. In all honesty, it's more trouble than it's worth.

As Solaire explains when players first encounter him, time and space act strangely in Lordan, and, as a result, it's difficult to interpret exactly where and when certain things took place in the lore.

This also calls into question the location of the Kiln of the First flame. Some believe that it's far below Firelink Shrine, though we don't know exactly where Kingseeker Frampt takes us. It can't be seen from any other location in the game, and some have speculated that it may, in fact, be found in an entirely different place and time.

Dedicated Dark Souls fans will know that the series culminates with a return to the Kiln of the First Flame at the end of Dark Souls 3. However, this time around, it looks completely different.

This adds fuel to the theory that the Kiln exists outside of the regular flow of time. However, millennia have supposedly past between the first and third Dark Souls titles, so it could be that this is, in fact, the same Kiln, though it's been drastically changed over all that time.

While the Kiln of the First Flame is an excellent place for collecting Black Knight weapons in the original Dark Souls, it's also an awesome spot for those hoping to farm some vital upgrade materials before the final encounter.

The Black Knights in the area will almost always drop regular, red, blue, and white titanite chunks. These are fairly tough to come across in the regular game and would ordinarily require a fair amount of grinding. However, making a few runs through the Kiln and then returning to a blacksmith should make certain upgrade processes much less taxing.

Another popular Dark Souls theory posits that the Kiln of the First Flame was actually originally constructed in what became Lost Izalith. The city is located inside of a giant dome, which some have likened to an actual kiln. Additionally, we know that Lost Izalith is where the Witch of Izalith attempted to recreate the First Flame, meaning that the Kiln of the First Flame would have been redundant.

However, The Witch of Izalith failed and created the Chaos Flame, spawning the demons of Lordran. Had things turned out differently, the events of Dark Souls may very well would never have come to pass.

Many players believe the so-called "canon" ending of Dark Souls to be the one which sees the Chosen Undead linking the fire and perpetuating Gwyn's age of light. However, according to some players, there is no true canon ending, and the player's choice ultimately doesn't impact the rest of the series.

Dark Souls' final boss theme has gained notoriety over the years for its shockingly dark and emotional tone, which stands in stark contrast to most of the game's other tracks. However, when breaking down the song's composition, things get even sadder.

Gwyn's theme is played entirely on whitealso known as naturalkeys. This was done purposefully, as Gwyn represents the light and opposes the darkness of humanity. This shows an outrageous amount of dedication to lore of which most players will only have a cursory knowledge.

rotary kiln product quality forecasting based on flame imaging - sciencedirect

For most applications, the rotary kiln product quality control problem is to apply a certain temperature profile to the solids within the kiln through direct contact with a hot flue gas produced by combustion. Since it is very difficult to measure the solids temperature profile in the kiln, due to the harsh environment and the rotating motion of the shell, quality control is often achieved in practice by controlling the solids discharge temperature close to some target value. The rational behind that is twofold: 1) the solids discharge temperature is often highly correlated to
