8th Special Issue on Z-PINCH PLASMAS

8th Brazilian Symposium on Programming Languages - J.UCS Special Issue

The Brazilian Symposium on Programming Languages (SBLP) is the main event in South America devoted to programming languages. Its scope includes all aspects of programming languages, including language design and implementation, formal semantics, domain-specific languages, and theoretical foundations of programming languages. The Symposium is a yearly event supported by the Brazilian Computer So...

K-shell radiation physics in low- to moderate-atomic-number z-pinch plasmas on the Z accelerator

Dense z-pinches produced by 100 ns implosions of wire arrays or gas puffs produce substantial soft X-ray power. One class of z-pinch radiation sources includes lowto moderate-atomic-number K-shell radiators, such as aluminum and iron. These loads are designed for 1–10 keV K-shell X-ray generation, and offer opportunities for crystal spectroscopy that can reveal fundamental properties of the pla...

Explosive Z Pinch

We propose an explanation for the recently observed powerful contained explosion in a Z pinch experiment performed at Sandia National Laboratories. Our arguments are based on the assumption that a pure SU(2) Yang-Mills theory of scale ∼ 0.5MeV is responsible for the emergence of the electron and its neutrino.

The main aim of this study is to develop part-of-speech tagger for Afaan Oromo language. After reviewing literatures on Afaan Oromo grammars and identifying tagset and word categories, the study adopted Hidden Markov Model (HMM) approach and has implemented unigram and bigram models of Viterbi algorithm. Unigram model is used to understand word ambiguity in the language, while bigram model is u...
