From an American Plantation to Interwar Poland: How Uncle Remus Became Bam-Bo the Negro

The article opens with the introduction of Joel Chandler Harris and his literary output. As one of “local colourists,” Harris depicted American plantation life in 19th-century Georgia and included many cultural as well as folk elements in his works. The following analysis of his stories about Uncle Remus focuses on (1) the levels of narration; (2) the linguistic complexity of the text (the stories abound in slang and dialectal expressions); (3) the form; and (4) the folklore value. These four aspects guide the discussion of the only Polish translation of the Uncle Remus stories. Prepared by Wladyslawa Wielinska in 1929, it was addressed to children. Therefore, the article aims to determine the profile of the translation as a children’s book, to consider it in relation to the skopos of the source text and to establish the extent to which it preserved the peculiar character of the Uncle Remus stories.

Improving RO PUF design using frequency distribution characteristics

<p>A Physical Unclonable Function (PUF) can be used to provide authentication of devices by producing die-unique responses. In PUFs based on ring oscillators (ROs) the responses are derived from the oscillation frequencies of the ROs. However, RO PUFs can be vulnerable to attack due to the frequency distribution characteristics of the RO arrays. In this letter, in order to improve the design of RO PUFs for FPGA devices, the frequencies of RO arrays implemented on a large number of FPGA chips are statistically analyzed. Three RO frequency distribution (ROFD) characteristics, which can be used to improve the design of RO PUFs are observed and discussed.p>

RO PUF Design in FPGAs with new comparison strategies

A Physical Unclonable Function (PUF) can be used to provide authentication of devices by producing die-unique responses. In PUFs based on ring oscillators (ROs), the responses are derived from the oscillation frequencies of the ROs. However, RO PUFs can be vulnerable to attack due to the frequency distribution characteristics of the RO arrays. In this paper, in order to improve the design of RO PUFs for FPGA devices, the frequencies of RO arrays implemented on a large number of FPGA chips are statistically analyzed. Three RO frequency distribution (ROFD) characteristics are observed and discussed. Based on these ROFD characteristics, two RO comparison strategies are proposed that can be used to improve the design of RO PUFs. It is found that the symmetrical RO comparison strategy has the highest entropy density.
