Little P.Eng. for Discrete Element Modeling (DEM) Services

In a world driven by technological advancements, the ability to understand granular systems at a particle level has never been more essential. This precise understanding has been made possible through a computational technique known as Discrete Element Modeling (DEM). While many entities offer DEM services, Little P.Eng. has carved a niche for itself as a front-runner in this specialized domain.

Understanding Discrete Element Modeling (DEM)

Before diving into the specifics of Little P.Eng.'s offerings, it's essential to demystify DEM:

DEM is Calculation-based Modeling: At the heart of DEM is mathematics. This method uses precise calculations to predict the behavior of individual particles within a system. By doing so, it can accurately predict the interactions and outcomes when these particles are subjected to various conditions.

DEM Allows for Visualizing Results: One of the standout features of DEM is its ability to provide visual results. Users can observe:

Particle Velocity: Understand the speed and direction of individual particles.

Forces: This includes shear (parallel to the surface) and normal (perpendicular to the surface) forces that the particles experience.

Moments: This refers to the bending and torsional (twisting) moments affecting the particles.

Acceleration and Material Scatter: Track how quickly particles move and the variations in their dispersion patterns.

DEM: More than just Flow Simulation: While DEM is instrumental in predicting the flow of bulk materials, its capabilities extend beyond this. It plays a crucial role in understanding:

Wear Patterns: Predict how equipment will fare over time by simulating particle interaction and the resultant wear.

Mixing: Understand how different particles mix, which is vital in industries like pharmaceuticals and food production.

Center Loading: This refers to the loading pattern where materials concentrate towards the center, crucial in industries like construction.

Anyways, Long Live my Anti-War Queens Elincia, Guinevere, Emmeryn and Ivy <3

TBH even here iirc some dude said the pyramids in Egypt are proof ancient Egyptians had access to electricity or something and when people called this nonsense some people defended the poster saying people who were debunking him were racist or something...

But tbh, who is the real mysoginist, the one who criticises a character based on her actions, or the one who "defends" her bringing up her gender?

And yeah, while Miccy, Elincia, Eirika and Celica were harshly shat upon back then, with copious amounts of double standards and it was hard not to see your usual brand of sexism, but imo it's not a reason to "play uno reverse" when it comes to defending Supreme Leader.

But for those devoted people, everything is fair game when it comes to defending their fave, I guess.

Review: Three Revolutionary Films by Ousmane Sembène on Criterion Blu-ray

Together, these films constitute a complex, interlocking portrait of Senegal’s past and present.

by Derek Smith May 30, 2024

Where Ousmane Sembène’s first two films, 1966’s Black Girl and 1968’s Mandabi, each focus on myriad struggles faced by an individual during Senegal’s early post-colonial years, his follow-up, Emitai, takes a more expansive view of the effects of colonialism two decades earlier. Centering on the defiance of a Diola tribe during World War II, 1971’s Emitai sacrifices none of the immediacy and urgency of Black Girl and Mandabi. Indeed, the film is perhaps an even more damning and incisive take-down of French colonial rule.

Painting a concise and pointed portrait of oppression in broad, revolutionary strokes, Emitai exposes the modern form of slavery that was France’s conscription of Senegalese men to fight on the deadliest frontlines of European battlegrounds. The film simultaneously details the meticulous taxation methods the French employed during this period, which, in attempting to seize a majority of tribes’ rice supply to feed their troops, is tantamount to starvation warfare.

Sembène, however, is less interested in the methodologies of the oppressor than in the unwavering, often silent protest of the Diola people, especially women, in the face of forces that threaten to wipe out the rituals and traditions that define them. In depicting the tribe’s refusal to turn over their rice not as a means to avoid starvation but as a matter of preserving the central value rice has in their cultural heritage, Sembène adds new dimensions to the conflict and complexity to the resistance of the villagers. The inevitable tragedy that concludes the film is quite the gut-punch, but in counterbalancing it with the rebellious enacting of funereal rites by the village women, Emitai becomes equal parts an indictment of colonial violence and a celebration of resilience and self-empowerment through revolutionary means.

In 1975’s Xala, Sembène presents a searing, often hilarious satire of the greed, corruption, and impotence of the new Senegalese governmental leadership following the eradication of French colonial rule. In the opening scene, we see government officials throw out the current French leaders and proudly proclaim that Africa will take back what’s theirs. This moment of triumph, which includes the removal of statues and busts of various French leaders, is swiftly undercut when the Senegalese officials each open a briefcase packed to the brim with 500 Franc bills.

This sequence, laden with anger and biting humor, is indicative of Xala’s absurdist, comedic tone. And as the film shifts its focus to one corrupt official in particular, El Hadji (Thierno Leye), who upon marrying his third wife is cursed with impotence, its satire becomes more metaphorical than direct. Sembène uses El Hadji’s gradual downfall to reflect the moral and political failings of the entire bourgeois class that came into power under the government of President Léopold Sédar Senghor. Through Sembène’s sly, cutting use of irony, claims of modernity and equality under a new “revolutionary socialism” are revealed to be empty promises, barely concealing the anti-feminist and pro-capitalist motives lurking behind them.

Sembène’s critique of a supposedly freed Senegal is intensely savage when it comes to unveiling the hypocrisies of a patriarchal leadership that betrayed the trust of the people it was supposed to aid and protect. Building to a conclusion that’s as funny and gratifying as it is pitiful and physically revolting, Xala captures the continuing repercussions of colonialism and how the forced delusions of a nation would leave its people perversely feeding on one another.

With 1977’s Ceddo, set in Senegal’s distant pre-colonial past, Sembène follows the conflicts between a growing Islamist faction of a once animistic tribe and the Ceddo, or outsiders, who refuse to convert and give up their animistic rituals and beliefs. This is certainly the most didactic entry in this set, but it’s enlivened by the sheer precision of its dialectical oppositions, through which the many hypocrisies of religious fundamentalism and colonization are laid bare.

Ceddo also reveals the complex intersectionality of religions and cultures that were at play in Senegal long before its colonization. Along with the Muslims, who were attempting to seize political power through religious conversions, white Christians and Catholics are present in the form of priests, missionaries, gun runners, and slave traders. The latter are silent through much of the film, but their presence—much like the white French adviser who remains in constant contact with the Senegalese politicians in Xala—speaks to the monumental power and influence whites held in Senegal even before colonialist rulers took over.

While the film’s subject is historical, Sembène draws clear parallels between the past and the post-colonial present of 1977, with the condescending paternalism of the Muslims, particularly the power-hungry imam played by Alioune Fall, mirroring that of the colonialist French. And rather than using traditional Senegalese music, Sembène employed Cameroonian musician Manu Dibango to compose a jazz-funk score that even further connects the events in Ceddo to the time of its release in the late ’70s. For whenever Sembène sets his film, he’s steadfast in his mission to draw meaningful correlations between Senegal’s past and present—each equally integral to the story of the country he loved and helped to define.

Image/Sound

All three transfers come from new 4K digital restorations and they, by and large, look terrific, with vibrant colors and rich details, especially in the costumes and extreme close-ups of faces. There are some shots where the grain is chunkier and the image isn’t quite as sharp, and the Ceddo transfer shows some noticeable signs of damage in several different scenes, but these are mostly minor, non-distracting imperfections. The mono audio track bears the limitations of the production conditions, so some of the dialogue in interior scenes is a bit echoey though still fairly clear. Meanwhile, the music comes through with a surprising robustness.

Extras

A new conversation between Mahen Bonetti, founder and executive director of the African Film Festival, and writer Amy Sall covers a lot of ground in 40 minutes. The two discuss Ousmane Sembène’s early career and discovery in the West before delving into his use of cinema as “a liberatory force” and his sly, caustic use of irony. The only other extra on the disc is a 1981 short documentary by Paulin Soumanou Vieyra in which Sembène espouses much of his philosophy of filmmaking, particularly the importance of understanding history and political complexities of the society one chooses to depict. (Amusingly, Sembène’s wife casually insults American moviegoers, as well as complains about her husband putting film before family.) The stunningly designed package also comes with a 26-page bound booklet containing an essay by film scholar Yasmina Rice, who touches on Sembène’s humor, feminism, and politically charged subjects, while forcefully pushing back against the notion that the director wasn’t much of a formalist.

Overall

These Ousmane Sembène films from 1970s brim with a revolutionary passion and, together, constitute a complex, interlocking portrait of Senegal’s past and present.
