Simple Random Access Compression
Fundamenta Informaticae, 2009Given a sequence S of n symbols over some alphabet Σ of size σ, we develop new compression methods that are (i) very simple to implement; (ii) provide O(1) time random access to any symbol (or short substring) of the original sequence. Our simplest solution uses at most 2h+o(h) bits of space, where h = n(H $_{0}$ (S)+1), and H $_{0}$ (S) is the zeroth-

Ferroelectric Random Access Memories
Journal of Nanoscience and Nanotechnology, 2012Ferroelectric random access memory (FeRAM) is a nonvolatile memory, in which data are stored using hysteretic P-E (polarization vs. electric field) characteristics in a ferroelectric film. In this review, history and characteristics of FeRAMs are first introduced. It is described that there are two types of FeRAMs, capacitor-type and FET-type, and that

[1991] Conference Record of the Twenty-Fifth Asilomar Conference on Signals, Systems & Computers, 2002
The authors describe an optical system that allows for the bit reversed decimation of an image scene. The optical system consists of a successive sequence of lens arrays. The output of one lens array feeds into the input of the next array. The function of each lens array is to divide the input into its four quadrants.

Random Access Versus Multiple Access
2018The support of Internet of Things (IoT) calls for physical and media access control (MAC) solutions capable to support a very large number of wireless devices transmitting short packets with low duty cycle. This chapter provides a survey of random access (RA) schemes devised for terrestrial and satellite applications which are suited to support IoT ...
