Vlad Trifa

Vlad Trifa is a computer science 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 Vlad Trifa rather than just read about it. In short: Vlad Trifa is a computer scientist, researcher and Chief Product Officer at Ambrosus who played a key role in defining and implementing the application layer of the Internet of Things. He is particularly known for his early contributions to the Web of Things along with other researchers such as Dominique Guinard, Erik Wilde and Friedemann Mattern.

Key takeaways

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

Reference excerpt

Vlad Trifa is a computer scientist, researcher and Chief Product Officer at Ambrosus who played a key role in defining and implementing the application layer of the Internet of Things. He is particularly known for his early contributions to the Web of Things along with other researchers such as Dominique Guinard, Erik Wilde and Friedemann Mattern. Vlad is widely published author and a recognized expert in distributed embedded sensing and interactive devices, and their integration with enterprise applications using Web technologies.

Career Vlad studied Computer Science at École Polytechnique Fédérale de Lausanne. After graduating from EPFL, he went on to get his PhD in Computer Science at ETH Zurich. During his time as a PhD he also worked as a Research Associate for SAP where he met Dominique Guinard. Both focused on the Internet of Things at SAP especially looking at the integration of real-world devices such as wireless sensor networks to business processes and enterprise software (e.g., ERPs). The complexity of these integrations at the time lead them to look simpler integration mechanisms. In 2007 they defined an application layer for the Internet of Things that uses Web standards called the Web of Things. Vlad wrote his Ph.D thesis on the Web of Things, particularly looking at the real-time aspects of Things on the Web. Towards the end of his Ph.D he experimented with applying the Web of Things concepts to smart cities and worked as a researcher in urban and mobile computing at SENSEable City Lab at MIT in Cambridge, USA and Singapore. In 2011, Vlad co-founded EVRYTHNG together with Dominique Guinard, Niall Murphy and Andy Hobsbawm. The founding idea of EVRYTHNG was to create digital identities and Web APIs for all kinds of objects: from consumer goods to consumer electronics. As such EVRYTHNG was the first commercial Web of Things platform. Vlad served as the Chief Product Officer and then EVP of Research and Development at EVRYTHNG before joining Swisscom to lead the Swisscom Digital Lab at École Polytechnique Fédérale de Lausanne. In 2015, Vlad co-authored the Web Thing Model which was accepted as an official W3C member submission. The Web Thing model is a first attempt at creating a simple Web based standard for the application layer of the Internet of Things.

Publications Vlad published a number of academic papers, largely related to the Internet of Things and the Web of Things. One of his most cited publications is "Towards the Web of Things: Web Mashups for Embedded Devices" which lays the foundations for integrating everyday devices and sensors to the Web. Vlad is also the co-author of Building the Web of Things, the first end to end manual for building Web connected devices.

Worked examples

Example 1 — a first encounter with Vlad Trifa

Start with the simplest possible case. Write down what Vlad Trifa claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, 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 Vlad Trifa 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 Vlad Trifa 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 Vlad Trifa

In research: Vlad Trifa appears in computer science 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 Vlad Trifa 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: Vlad Trifa is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1982 births, ETH Zurich alumni, Internet of things, so understanding it makes those chapters shorter.
In everyday life: Look for Vlad Trifa 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.
