Blockchain Technology: An Analysis of Potential Applications and Uses

This paper will focus on explaining what blockchain technology is, the fundamentals of how it works, and applications of it. By utilizing sophisticated cryptography, a distributed network, a specified order of events the technology is able to create a ledger that cannot be altered due to its existence on many computers that able to detect if the data has been changed or tampered with. To help illustrate the uses of blockchain technology the technical explanation is complemented with real and hypothetical ways that the technology it being used. The use of blockchain technology originated with financial application and has expanded to many industries as new and creative ideas come to fruition

A jelen tanulmány célja, hogy röviden számot adjon, a fogyatékos személyek jogairól és esélyegyenlőségük biztosításáról szóló, 1998. évi XXVI-os törvény keletkezésének körülményeiről, tartalmáról és az elfogadása óta eltelt időszak legfontosabb eredményeiről. (Magyarország 1999-ben negyedikként – Dél-Korea, Kanada és Írország után – az e cikkben leírt eredményekért, a fogyatékossággal élő emberek érdekében kifejtett tevékenységéért, Göncz Árpád köztársasági elnök és Harrach Péter miniszter pályázata nyomán elnyerte a Roosevelt-díjat.

On alpha stable distribution of wind driven water surface wave slope

We propose a new formulation of the probability distribution function of wind driven water surface slope with an $\alpha$-stable distribution probability. The mathematical formulation of the probability distribution function is given under an integral formulation. Application to represent the probability of time slope data from laboratory experiments is carried out with satisfactory results. We compare also the $\alpha$-stable model of the water surface slopes with the Gram-Charlier development and the non-Gaussian model of Liu et al\cite{Liu}. Discussions and conclusions are conducted on the basis of the data fit results and the model analysis comparison.Comment: final version of the manuscript: 25 page

Results of consecutive training procedures in pediatric cardiac surgery

This report from a single institution describes the results of consecutive pediatric heart operations done by trainees under the supervision of a senior surgeon. The 3.1% mortality seen in 1067 index operations is comparable across procedures and risk bands to risk-stratified results reported by the Society of Thoracic Surgeons. With appropriate mentorship, surgeons-in-training are able to achieve good results as first operators
