Learning Externally Modulated Dynamical Systems

Aude Billard, Klas Jonas Alfred Kronander, Nicolas Sommer

Dynamical Systems (DS) are often used to represent motion, with the advantage of being easy to learn from demonstrations. We present a method to modulate DS depending on an external signal, extending our previous work on Locally Modulated DS (LMDS, Kronand ...

Uniting Language Embeddings for Fast and Friendly DSLs

Vojin Jovanovic

The holy grail for a domain-specific language (DSL) is to be friendly and fast. A DSL should be friendly in the sense that it is easy to use by DSL end-users, and easy to develop by DSL authors. DSLs can be developed as entirely new compilers and ecosystem ...

How to Architect a Query Compiler

Christoph Koch, Amir Shaikhha, Lionel Emile Vincent Parreaux, Ioannis Klonatos, Mohammad Dashti Rahmat Abadi

This paper studies architecting query compilers. The state of the art in query compiler construction is lagging behind that in the compilers field. We attempt to remedy this by exploring the key causes of technical challenges in need of well founded soluti ...

Architectural Modeling of a Multi-Tone/Single-Sideband Serial Link Transceiver for Lossy Wireline Data Links

Yusuf Leblebici, Gain Kim

This paper presents a serial link transceiver (TRX) architecture that enables high-speed data transmission over a lossy backplane channel without the presence of equalization circuits. The proposed architecture employs multi-tone signaling to reduce inter- ...

Forge: Generating a High Performance DSL Implementation from a Declarative Specification

Martin Odersky, Tiark Rompf

Domain-specific languages provide a promising path to automatically compile high-level code to parallel, heterogeneous, and distributed hardware. However, in practice high performance DSLs still require considerable software expertise to develop and force ...

High Symbol Rate Coherent Optical Transmission Systems: 80 and 107 Gbaud

Rüdiger Urbanke, Luis Salamanca Miño

We demonstrate high speed optical transmission systems using digital coherent detection at all-electronically multiplexed symbol rates of 80 and 107 Gbaud. At 107 Gbaud, we demonstrate a single-carrier polarization division multiplexed quadrature phase shi ...

Tracking freeriders in gossip-based content dissemination systems

Rachid Guerraoui, Anne-Marie Kermarrec, Kévin Clément Huguenin, Maxime Monod

Gossip-based protocols have proven very efficient for disseminating high-bandwidth content such as video streams in a peer-to-peer fashion. However, for the protocols to work, nodes are required to collaborate by devoting a fraction of their upload bandwid ...

Insomnia in the Access (or How to Curb Access Network Related Energy Consumption)

Dejan Kostic, Marco Canini

Access networks include modems, home gateways, and DSL Access Multiplexers (DSLAMs), and are responsible for 70-80% of total network-based energy consumption. In this paper, we take an in-depth look at the problem of greening access networks, identify root ...
