Acoustic data communication for industrial drilling applications by Goh, Cher Shin.

“…Project B5035-121, Acoustic Data Communication for Industrial Drilling Applications, looks at the possible ways of incorporating the multilevel modulation of Amplitude Shift Keying-Frequency Shift Keying (ASK-FSK) into the transceiver architecture of an acoustic telemetry system, such that the architecture embodies balance of good traits, such as high data transmission rates and good bit error rate (BER) performance. This is due to the greater need for communication systems of industrial drilling applications to have a higher throughput. …”

A highly strained Al-Al σ-bond in dianionic aluminum analog of oxirane for molecule activation by Koshino, Kota, Kinjo, Rei

“…The structure of 2 has been unambiguously ascertained by spectroscopic analysis as well as X-ray crystallography, and computational studies revealed that 2 bears a highly strained Al-Al σ-bond. 2 readily reacts with the unsaturated substrates such as isocyanide, ethylene, and ketone, concomitant with the cleavage of the Al-Al σ-bond under mild conditions, leading to the four- and five-membered heterocycles 3-5. …”

Why Brussels? Neruda’s ‘título absolutamente enigmático’ by Moran, D

“…<p>The primary purpose of this article is to propose a solution to longstanding literary mystery, namely, why Neruda&rsquo;s disconcertingly enigmatic poem &lsquo;Bruselas&rsquo; (from&nbsp;<em>Tercera residencia</em>&nbsp;[1947]) has a title which seems to bear little if any relation either to the city of Brussels itself or to its sometimes bewilderingly obscure content and imagery. …”

Iterative decoding of cyclic codes based on FFT sliding correlator by Mohammad Ridwan Septadi.

“…We successfully designed the soft-in-hard-out ML-decoding of cyclic code based on sliding correlator. BER performance results indicate that our decoder performs well as it meets the theoretical expectation by having performance curves which are slightly better than the theoretical upper bound by 0.3-0.4dB for various BCH codes. …”
