Chromatic dispersion is one of the most significant impairments in long-distance fiber-optical communications. Electrical domain compensation of optical chromatic dispersion by signal predistortion using digital processing is investigated with two different approaches: using a linear digital FIR compensating filter and using a nonlinear filter based on a look-up table (LUT). The linear compensa...

The paper proposes the technology of control of integrity and legitimacy of information object usage with the Look Up Table-oriented (LUToriented) architecture. The technology is based on embedding the self-recovery digital watermark into information objects of such kind. The technology is the composition of approaches to forming the self-recovery digital watermarks in the passive multimedia co...

OBJECTIVES Dementia with Lewy bodies (DLB) is the second most common degenerative cause of dementia, whereas lower urinary tract (LUT) function in DLB patients has not been fully delineated. We investigated LUT function in DLB by clinical-urodynamic observations. METHODS We examined 32 patients with DLB (23 men, 9 women; aged 59-86 [mean, 75.9] years; disease duration, 0.2-17 [3.3] years). Al...

This paper studies joint security and robustness enhancement of quantization-based data embedding for multimedia authentication applications. We present analysis showing that through a lookup table (LUT) of nontrivial run that maps quantized multimedia features randomly to binary data, the probability of detection error can be considerably smaller than the traditional quantization embedding. We...

A multiple-output function can be represented by a binary decision diagram for characteristic function (BDD for CF). This paper presents a method to represent multiple-output incompletely specified functions using BDD for CFs. An algorithm to reduce the widths of BDD for CFs is presented. This method is useful for decomposition of incompletely specified multiple-output functions. Experimental r...

the highest temperatures of the world are recorded in dry and warm climates. this can especially be observed in deserts, where vegetations and soil moisture are very low. as a result, the soil surface receives high thermal energy and its temperature rises up. the lut desert has the above characteristics, making it a suitable environment to prepare land surface temperature (lst) models. objectiv...

The use of Look-Up Tables (LUTs) is extended from binary to multiple-valued logic (MVL) circuits. A multiple-valued LUT can be implemented using both current-mode and voltage-mode techniques, reducing the transistor count to half compared to that of a binary implementation. Two main applications for multiple-valued LUTs are multiple-valued FPGAs and intelligent memories. An FPGA uses a LUT as a...

This paper presents a hybrid logic simulator using both an event-driven and a cycle-based methods. For special primitives such as memories and tri-state buffers, it uses an event-driven method. For other parts, it uses a cyclebased method using LUT cascade emulators. To simulate a large scale circuit, it partitions the circuit into smaller ones, and realizes each part by an LUT cascade emulator...
