Jie Wu

Jie Wu 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 Jie Wu rather than just read about it. In short: Jie Wu (Chinese: 吴杰; pinyin: Wú Jié) is a Chinese computer scientist. He is a Professor Emeritus at College of Science and Technology: Computer and Information Sciences department at Temple University.

Key takeaways

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

Reference excerpt

Jie Wu (Chinese: 吴杰; pinyin: Wú Jié) is a Chinese computer scientist. He is a Professor Emeritus at College of Science and Technology: Computer and Information Sciences department at Temple University. He served as Program Director of Networking Technology and Systems (NeTS) at the National Science Foundation from 2006 to 2008. Jie Wu is noted for his research in routing for wired and wireless networks. His main technical contributions include fault-tolerant routing in hypercube-based multiprocessors, local construction of connected dominating set and its applications in mobile ad hoc networks, and efficient routing in delay tolerant networks, including social contact networks. He served as the General Chair of IEEE ICDCS 2013, IEEE IPDPS 2008, and IEEE MASS 2006 and the Program Chair of CCF CNCC 2013, IEEE INFOCOM 2011, and IEEE MASS 2004. He is a Fellow of IEEE, for contributions to mobile ad hoc networks and multicomputer systems, and serves on the editorial board for a number of journals, including IEEE Transactions on Computers (TC), IEEE Transactions on Services Computing (TSC), and Journal of Parallel and Distributed Computing (JPDC). He received 2011 China Computer Federation (CCF) Overseas Outstanding Achievements Award. He was a Fulbright Senior Specialist. He was also an IEEE Distinguished Visitor, an ACM Distinguished Member and a CCF Distinguished Speaker. He resides in Fort Washington, Pennsylvania.

Worked examples

Example 1 — a first encounter with Jie Wu

Start with the simplest possible case. Write down what Jie Wu 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 Jie Wu 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 Jie Wu 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 Jie Wu

In research: Jie Wu 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 Jie Wu 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: Jie Wu is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computer scientist stubs, Educators from Shanghai, Living people, so understanding it makes those chapters shorter.
In everyday life: Look for Jie Wu 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.

Frequently asked questions

What is Jie Wu in simple terms?

Why does Jie Wu matter?

Because it connects several astronomy ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Jie Wu?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
