An evolutionary algorithm based on Random Keys to represent Golomb Rulers segments has been found to be a reliable option for finding Optimal Golomb Rulers in a short amount of time, when comparing with standard methods. This paper presents a modified version of this evolutionary algorithm where the maximum segment length for a Golomb Ruler is also part of the evolutionary process. Attained exp...

This paper focuses on the performance evaluation of complex man-made systems, such as assembly lines, electric power grid, traffic systems, and various paper processing bureaucracies, etc. For such problems, applying the traditional optimization tool of mathematical programming and gradient descent procedures of continuous variables optimization are often inappropriate or infeasible, as the des...

In this paper, we present a new family of 3-D single pulse per plane codes for differential detection (SPDD) for optical cdma systems (based on the 1-D golomb ruler sequences), which achieve good code cardinality and a very high BER performance. The improved BER performance is obtained by using two codes to encode ‘1’ and ‘0’ bits in the encoder and adopting the Differential Detection in the re...

The aim of this project is the development of a pedagogical tool that could address the needs related to the learning process of the blind and could also be used in the pedagogical process of people who are visually impaired. This project also has the objective of showing how the forms of the Ruler of Inclusion were planned in order to facilitate learning while addressing issues related to its ...

Abstract How should we understand the Confucian doctrine of rectification names (zhengming): what does it mean that an object’s name must be in accordance with its reality, and why matter? The aim this paper is to answer question by advocating a novel interpretation later Confucian, Xunzi’s account doctrine. Xunzi claims sage-kings ascribe values objects convention, since they are sages, know t...

A new architecture for Golomb ruler derivation has been developed, and a FPGA-based custom compute engine of the new architecture has been fully designed. The new FCCM, called GE1, is presented in terms of its datapath, and control path. Portions of the GE1 have been implemented to verify functional correctness and accuracy of the simulation results. The new machine requires twenty Xilinx 5000 ...

PURPOSE To describe the use of a ruler to increase the accuracy and customization of Lester Jones tube placement. MATERIALS AND METHODS This was a review of 92 patients who underwent minimally invasive conjunctivodacryocystorhinostomy using this instrument. RESULTS The success rate was 100%, with an average operating time of 15 minutes. In nine patients, late migration of the Jones tube int...

A Ruler Array measures the distance between a set of microarray probes and a set of experimentally defined locations in a nucleic acid, offering new possibilities for locating and characterizing changes in the nucleic acid sequence. Despite the known relevance of genomic changes to pathogens, cancer, development, and evolution, many of these changes evade detection by existing high-throughput t...
