Hendrik C. Ferreira

Hendrik C. Ferreira is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hendrik C. Ferreira rather than just read about it. In short: Hendrik Christoffel Ferreira (1954 – November 20, 2018, in Johannesburg) was a professor in Digital Communications and Information Theory at the University of Johannesburg, Johannesburg, South Africa. Biography He studied electrical engineering at the University of Pretoria, South Africa, where he obtained his Ph.D. in 1980.

Key takeaways

  • Hendrik C. Ferreira belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Hendrik C. Ferreira to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Hendrik C. Ferreira from memory before moving on to harder problems.

Reference excerpt

Hendrik Christoffel Ferreira (1954 – November 20, 2018, in Johannesburg) was a professor in Digital Communications and Information Theory at the University of Johannesburg, Johannesburg, South Africa.

Biography He studied electrical engineering at the University of Pretoria, South Africa, where he obtained his Ph.D. in 1980. He worked as a visiting researcher at Linkabit in San Diego. He joined the Rand Afrikaans University in 1983, where, in 1989, he was appointed full professor. In recognition of his excellence in research and educating post-graduate students, he has been appointed as a research professor at the University of Johannesburg in 2007. He is a Fellow of the SAIEE, the South African Institute of Electrical Engineers. Ferreira published close to 250 research papers on topics such as digital communications, power line communications, vehicular communication systems. With his work he introduced and developed a new theme in Information Theory, namely coding techniques for constructing combined channel codes, where error correction and channel properties are considered jointly. Ferreira was a pioneering initiator and stimulator of the research fields of Information Theory and Power Line Communications in South Africa. He also was an organizer of the IEEE Information Theory Society and Power Line Communications within South Africa and Africa. He was a member of the Technical Committee for Power Line Communications of the IEEE Communications Society, and he served on the Technical Program Committee of several IEEE conferences, including the IEEE (ISIT) International Symposium on Information Theory, the IEEE (ISPLC) International Symposium on Power Line Communications, and the IEEE Africon and Chinacom conferences. An obituary by his colleague Han Vinck was presented during a workshop in 2019.

Worked examples

Example 1 — a first encounter with Hendrik C. Ferreira

Start with the simplest possible case. Write down what Hendrik C. Ferreira claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hendrik C. Ferreira before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hendrik C. Ferreira ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hendrik C. Ferreira

In research
Hendrik C. Ferreira appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Hendrik C. Ferreira in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Hendrik C. Ferreira is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1954 births, Academic staff of Rand Afrikaans University, Academic staff of the University of Johannesburg, so understanding it makes those chapters shorter.
In everyday life
Look for Hendrik C. Ferreira outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
