Bitcoin elektronisessa liiketoiminnassa : haasteet ja mahdollisuudet

2016

Digitaalinen raha ja maksujärjestelmä Bitcoin on herättänyt paljon huomiota viime vuosina. Elektronisen liiketoiminnan toimijat ovat kuitenkin olleet hitaita hyväksymään Bitcoinin maksuvälineenä. Syynä tähän on sen kyseenalainen maine ja riskit. Tämän kandidaatintutkielman tarkoituksena oli selvittää Bitcoinin hyödyt ja haitat elektronisessa liiketoiminnassa. Toisena tavoitteena oli selvittää, miten Bitcoinia on ehdotettu kehitettäväksi, jotta siitä tulisi varteenotettavampi maksuväline. Tutkimusmenetelmänä käytettiin kirjallisuuskatsausta. Bitcoinin tärkeimmiksi hyödyiksi havaittiin muun muassa alhaiset transaktiokustannukset etenkin mikromaksumarkkinoilla ja sen pohjalla olevan teknologia…

Decoupled control scheme of grid-connected split-source inverters

2017

Grid-connected power conversion systems for renewable energy sources must fulfill several requirements, e.g., the high efficiency, the reduced cost and complexity, and, quite often, the boost capabilities that is usually achieved using a front-end dc–dc boost converter before the inversion stage, leading to a two-stage architecture. Meanwhile, single-stage power conversion systems, which perform the boosting operation within the inversion one, offer some potential advantages, in terms of reducing the complexity and the volume of the whole system. Among several proposed options, the split-source inverter (SSI) has been recently proposed by Abdelhakim et al. as an alternative option with some…

"Co to są czary? Co za znaki ich?" Litewskie kazanie i sposoby na czary z końca XVII i XVIII w

2018

Witchcraft as a crime attracted the attention of Polish-Lithuanian society in many aspects at the turn of 17th and 18th centuries. On the one hand, it was connected with a belief in its efficiency, in the existence of witches and sorcerers, and their covenant with the devil. The article analyzes two manuscripts: a prayer „Modlitwa przeciwko czarom i niebezpieczeństwom” and a sermon „ Jako się strzedz czarów i potwarzy o nie”. The sermon utilizes contemporary rhetoric, stresses the importan-ce of sin and appeals to the receivers through fear. What is somewhat surprising, the text maintains that most witchcraft happened with God’s permission, as God allows the devil to function in the society…

Extended Families as Communities of Religious Experience in Late Seventeenth-Century Eastern Finland

2022

AbstractThis chapter offers an interpretation of extended families as communities of experience in a rural area close to the eastern border of the Swedish realm. Through a case study of lower court records, Kuha examines the social and religious life in a 17th-century farm culminating in the crisis of an extended family. The chapter explores how practices of lived religion shaped the relationship of the community and the individual, and how experiences were negotiated within families and local communities. The analysis highlights the importance of protecting the boundaries of the household as well as the meaning of religious practices in creating cohesion within the community.

Effect of pulse amplitude on depression and potentiation of ZrO2(Y)-based memristive synaptic device

2022

The effect of the amplitude of depressing and potentiating pulses on the synaptic plasticity (potentiation and depression) of a memristive device based on the Ta/ZrO2(Y)/Pt stack has been experimentally studied. It is shown that the amplitude of depressing and potentiating pulses affects the synaptic plasticity, namely, the value of current passing through the memristive device. The presented results demonstrate the prospects of using the ZrO2(Y)-based memristive devices as stable and low-power elements of neuromorphic systems.
