Use Case: Julia Programming Language for Artificial Intelligence

Julia is a programming language that has gained popularity in the field of artificial intelligence (AI) and scientific computing for several reasons.

High Performance: Julia is designed to be a high-performance language, often compared to languages like C and Fortran. It achieves this performance through just-in-time (JIT) compilation, allowing it to execute code at speeds close to statically compiled languages. This makes Julia well-suited for computationally intensive AI tasks such as numerical simulations and deep learning.

Ease of Use: Julia is designed with a clean and expressive syntax that is easy to read and write. It feels similar to other high-level languages like Python, making it accessible to developers with a background in Python or other scripting languages.

Multiple Dispatch: Julia’s multiple dispatch system allows functions to be specialized on the types of all their arguments, leading to more generic and efficient code. This feature is particularly useful when dealing with complex data types and polymorphic behavior, which is common in AI and scientific computing.

Rich Ecosystem: Julia has a growing ecosystem of packages and libraries for AI and scientific computing. Libraries like Flux.jl for deep learning, MLJ.jl for machine learning, and DifferentialEquations.jl for solving differential equations make it a powerful choice for AI researchers and practitioners.

Interoperability: Julia offers excellent interoperability with other languages, such as Python, C, and Fortran. This means you can leverage existing code written in these languages and seamlessly integrate it into your Julia AI projects.

Open Source: Julia is an open-source language, which means it is freely available and has an active community of developers and users. This makes it easy to find resources, documentation, and community support for your AI projects.

Parallel and Distributed Computing: Julia has built-in support for parallel and distributed computing, making it well-suited for tasks that require scaling across multiple cores or distributed computing clusters. This is beneficial for large-scale AI projects and simulations.

Interactive Development: Julia’s REPL (Read-Eval-Print Loop) and notebook support make it an excellent choice for interactive data analysis and experimentation, which are common in AI research and development.

While Julia has many advantages for AI applications, it’s important to note that its popularity and ecosystem continue to grow, so some specialized AI libraries or tools may still be more mature in other languages like Python. Therefore, the choice of programming language should also consider the specific requirements and constraints of your AI project, as well as the availability of libraries and expertise in your development team.

ABSTRACT.  Many optimization problems in power transmission networks can be formulated as polynomial problems with complex variables. A polynomial optimization problem with complex variables consists in optimizing a real-valued polynomial whose variables and coefficients are complex numbers subject to some complex polynomial equality or inequality constraints. These problems are usually directly expressed with real variables. In this work, we propose a Julia module allowing the representation of polynomial problems in their original complex formulation. This module is applied to power system optimization and its generic design enables the description of several variants of power system problems. Results for the Optimal Power Flow in Alternating Current problem and for the Preventive-Security Constrained Optimal Power Flow problem are presented.

Lifts, escalators & moving walks

At the 1853 New York World’s Fair Elisha Otis amazed a crowd when he ordered the only rope holding the platform on which he was standing cut by an axeman. The platform fell only a few inches before coming to a halt; thus proving the safety locking mechanism he had invented will work. These elevators quickly became the type in most common usage and made vertical living possible.

Most large research universities have 100 – 1000 elevators that are highly regulated, maintained by highly regulated service personnel and inspected by highly trained conformance operatives; thus our primary interest in state-specific regulations.  We have a  secondary interest in innovation in the technology generally.  Many sustainability goals urged in academic circles  — which include greater population density in smaller areas — are challenged by mobility issues.

From the project prospectus:

“…The main feature of these products is that they are an integral part of industrial, residential or public buildings. Consequently, they should be adaptable to the technical and architectural constraints of such buildings. They must also meet the capacity requirements imposed by the intended use of the building. These products are considered as means of transport and therefore represent an essential component of the functional life of the buildings in which they are installed. Contrary to most public means of transport, they are intended for free use and operation by their passengers, which makes the integration of safety an essential concern…”

Qu’est-ce qu’une nation?

Ernest Renan (1823-1892) was a French philosopher, historian, and scholar of religion. He is best known for his work on nationalism and the relationship between language, culture, and identity.  The language of technology– and the catalog of codes, standards, guidelines, recommended practices and government regulations rest upon a common understanding of how things can and should work separately.  The essay is widely cited:

Qu’est-ce qu’une nation ?

English and French are the two most prominent diplomatic languages, especially in historical and international contexts. They have long been the primary languages of diplomacy due to their widespread use in international organizations and historical influence.

English: Dominates in modern diplomacy, international law, and global organizations. It is the working language in many international forums, including the United Nations, NATO, and the Commonwealth of Nations.

French: Traditionally known as the “language of diplomacy,” French was the dominant diplomatic language until the 20th century. It remains a significant language in international relations, particularly within the United Nations, the European Union, and many African nations.

While other languages like Spanish, Arabic, Russian, and Chinese are also used in diplomatic contexts and are official languages of the United Nations, English and French are the most universally recognized and utilized in diplomatic settings.

Alexis de Tocqueville on the Foundations of American Democracy

Alexis de Tocqueville was born in Paris and came from a prominent lineage, with his father serving as a royalist prefect under the Bourbon restoration.

In 1831, at the age of twenty-five, Alexis de Tocqueville made his fateful journey to America, where he observed the thrilling reality of a functioning democracy. From that moment onward, the French aristocrat would dedicate his life as a writer and politician to ending despotism in his country and bringing it into a new age.



Quotes from Alexis de Tocqueville’s “Democracy in America”:

  1. “The greatness of America lies not in being more enlightened than any other nation, but rather in her ability to repair her faults.”
  2. “Americans are so enamored of equality that they would rather be equal in slavery than unequal in freedom.”
  3. “In democratic ages, human beings rarely sacrifice themselves for one another voluntarily; they almost always do so because they are impelled to by some power outside themselves.”
  4. “Despotism often presents itself as the repairer of all ills suffered, the support of just rights, defender of the oppressed and founder of order.”
  5. “The best laws cannot make a constitution work in spite of morals; morals can turn the worst laws to advantage.”
  6. “I do not know if the people of the United States would vote for superior men if they ran for office, but there can be no doubt that such men do not run.”
  7. “The most dangerous moment for a bad government is when it begins to reform.”
  8. “The Americans combine the notions of Christianity and of liberty so intimately in their minds that it is impossible to make them conceive the one without the other.”
  9. “The will of man is not shattered, but softened, bent, and guided; men are seldom forced by it to act, but they are constantly restrained from acting. Such power does not destroy, but it prevents existence; it does not tyrannize, but it compresses, extinguishes, and stupefies a people, till each nation is reduced to nothing better than a flock of timid and industrious animals, of which the government is the shepherd.”
  10. “Americans combine the notions of Christian morality and of liberty so intimately in their minds that it is impossible to make them conceive the one without the other.”
  11. “In the United States, the most enlightened are the most religious; and the most religious are the most enlightened.”
  12. Americans of all ages, all conditions, and all dispositions constantly form associations… Wherever at the head of some new undertaking you see the government in France, or a man of rank in England, in the United States you will be sure to find an association.”

“Cantique de Jean Racine” Gabriel Fauré.

Gabriel Fauré’s “Cantique de Jean Racine” is a choral work composed in 1865 when Fauré was 19. Written for a four-part choir, it’s a setting of a Latin text by the 17th-century French playwright Jean Racine, which reflects a deep, devotional tone. The text is a hymn of praise and supplication, asking for divine grace and mercy.

Fauré’s composition is noted for its lyrical beauty and sophisticated harmony, showcasing his early mastery of choral writing. The piece begins with a serene, flowing melody in the sopranos, which is then developed and harmonized throughout the choir. The work features lush, rich chords and a gentle, flowing rhythm, characteristic of Fauré’s style, blending simplicity with depth. Its mood is one of quiet contemplation and reverence, aligning with the text’s themes of divine worship and reflection.
