EPC: A Provably Secure Permutation Based Compression Function
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2010 The security of permutation-based hash functions in the ideal permutation model has been studied when the input-length of compression function is larger than the input-length of the permutation function.

Aggregation Rate for Compressible Functions
Proceedings of the 18th ACM International Symposium on Mobile Ad Hoc Networking and Computing, 2017One of the most fundamental tasks in sensor networks is the computation of a (compressible) aggregation function of the input measurements. What rate of computation can be maintained, by properly choosing the aggregation tree, the TDMA schedule of the tree edges, and the transmission powers? We show here that the optimal rate is effectively a constant.

Engineering Compressed Static Functions
2018 Data Compression Conference, 2018Recent advances in the compact representation of static functions (with constant access time) have made it possible to fully exploit constructions based on random linear system. Such constructions, albeit theoretically appealing, were previously too slow to be usable.

Performance as a function of compression
IBM Journal of Research and Development, 1998This paper discusses the performance of bilevel-image arithmetic coders, ABIC and JBIG, and Lempel-Ziv string compressors, ALDC and BLDC. Images are analyzed for typical and worst-case throughput and latency as a function of compression. A relationship between the compressibility of an image and the throughput performance of the compression algorithm ...

On Distributed Compression of Linear Functions
IEEE Transactions on Information Theory, 2008We consider distributed compression of a pair of Gaussian sources in which the goal is to reproduce a linear function of the sources at the decoder. It has recently been noted that lattice codes can provide improved compression rates for this problem compared to conventional, unstructured codes.

On Approximation of Bandlimited Functions with Compressed Sensing
2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018The application of Compressed Sensing techniques to bandlimited functions is investigated in this paper. It is shown that under the assumption of sparsity, stable reconstruction of a bandlimited function is possible from finitely many samples, contrary to classical results from signal processing theory.

Constructing Compression Functions
2021We have seen that cryptographic hash functions that can process arbitrarily long inputs can be built from fixed-input-length compression functions via the Merkle–Damgard transformation (Chapter 13).

On the Weak Ideal Compression Functions
2009In SAC 2006, Liskov introduced the weak ideal compression functions. He proved that a hash construction based on these functions is indifferentiable from the random oracle. In ICALP 2008, Hoch and Shamir applied Liskov's idea and proved the indifferentiability of another hash construction.

Effects of Tourniquet Compression on Neuromuscular Function
Clinical Orthopaedics and Related Research, 1999Neuromuscular function in New Zealand White rabbits was evaluated after thigh tourniquet compression in the directly compressed quadriceps muscles and the distal tibialis anterior by measuring isometric contractile function after supramaximal stimulation of the motor nerve.
