A Peer-to-Peer Market Algorithm for a Blockchain Platform

2020

In an era of technological revolution in which everything becomes smarter and connected, the blockchain can introduce a new model for energy transactions able to grant more simplicity, security and transparency for end-users. The blockchain technology is characterized by a distributed architecture without a trusted and centralized authority, and, therefore, it appears as the perfect solutions for managing exchanges between peers. In this paper, a market algorithm that can be easily transferred to a smart contract for maximizing the match between produced and consumed energy in a micro-grid is presented. The algorithm supports energy transactions between peers (both producers and consumers) …

Aggregation and remuneration in Demand-Response with a blockchain-based framework

2020

This paper describes the possibility to use the blockchain technology for load and generation aggregation in a new distributed Demand Response (DR) service and customers remuneration system. The blockchain technology and the use of smart contracts for DR allow the creation of a distributed system in which customers can communicate directly, in a transparent, secure and traceable way, with the grid operator to provide their flexibility. In this paper, the DR problem formulation takes into account several aspects, which are periodically executed. First, the blockchain records customers’ energy consumption or production, then, the smart contract starts calculating the baseline and the potentia…

Robust auto calibration technique for stereo camera

2017

Calibration of the internal and external parameters of a stereo vision camera is a well-known research problem in the computer vision. Usually, to get accurate 3D results the camera should be manually calibrate accurately as well. This paper proposes a robust approach to Auto Calibration stereo camera Without intervention of the user. There are several methods and techniques of calibration that have been proven, in this work we exploiting the geometric constraint, namely, the epipolar geometry. We specifically focuses to use 7 techniques for Features Extraction (SURF, BRISK, FAST, FREAK, MinEigen, MSERF, SIFT), however tries to establish the correspondences between points extracted in stere…

Evaluation of Banking Digitization Policy of Romanian Commercial Banks

2018

Nowadays, even in Romania, we faced with process of digitalization of financial system, especially of banking system. Natural person—banks relationships are more and more distant as location, but more and faster as financial transaction results, because of banking digitalization process based on performance of internet era. The paper’s aims are to answer to questions like: Are Romanian past, actual and future generations prepared to be fully integrated in banking digitalization process? Do Romanian natural person understands the usefulness and benefits of digital banking services/? Or, how benefits of Romanian commercial banks are changing? The methodological support includes analyzing empi…

Extending the Transactional View on Public–Private Partnership Projects: Role of Relational and Motivational Aspects in Goal Alignment

2019

AbstractIn public–private partnerships (PPPs), aligning the goals of the public sector with those of the private contractor is usually achieved using incentives informed by agency theory. However, ...

Realisation of strategic leadership in leadership teams' work as experienced by the leadership team members of basic education schools

2013

This article introduces a quantitative research into how the leadership team members of 49 basic education schools in the city of Vantaa, Finland, experienced the realisation of strategic leadership in their leadership teams' work. The data were collected by a survey of 24 statements, rated on a five-point Likert scale, and analysed with the Statistical Package for the Social Sciences (SPSS). The only variant explaining the differences in experiencing the realisation of strategic leadership in the leadership teams' work statistically, almost significantly, was the leadership team membership.

How Followers Differing in Career Motivation Gain Career Profits from Transformational Leaders: A Longitudinal Moderated Mediation Model

2017

Although, transformational leadership is among the most thoroughly examined leadership theories, knowledge regarding its association with followers' career outcomes is still limited. Furthermore, the underlying mechanisms explaining how transformational leaders affect their employees' career success are yet not well-understood. Based on theoretical assumptions about the processes involved in setting the goal of “making a career,” we propose an indirect effect of transformational leadership on subjective and objective career success via development opportunities that depends on the level of career motivation of employees. We conducted a longitudinal study with two measurement occasions separ…

Extraction Chromatographic Behavior of Rf, Zr, and Hf in HCl Solution with Styrenedivinylbenzene Copolymer Resin Modified by TOPO (trioctylphosphine …

2010

It is of great interest to study chemical properties of the transactinide elements with atomic numbers (Z) ≥ 104. One of the most important subjects is to establish the position of the elements at the extreme end of the periodic table. To this end we perform studies of chemical properties of these transactinides and compare them with those of their lighter homologues and with the ones expected from extrapolations in the periodic table. So far, chromatographic studies of the transactinides have provided experimental proof of placing rutherfordium (Rf, Z = 104) through hassium (Hs, Z = 108) into groups 4 to 8, respectively. 1-10 Quite recently, copernicium (Cn, Z = 112) has been shown to be a…

Examining key drivers of consumer experience with (non-financial) digital services : An exploratory study

2020

Recent advancements in the field of mobile information systems have transformed the consumer lifestyle as well as have changed the digital service landscape globally. This exploratory study identifies and describe key marketing drivers of consumer experience with non-financial transactions available on mobile banking apps. Data were gathered using semi-structured in-depth interviews from 12 respondents in Finland during March and April 2019. The qualitative analysis of the interview transcripts revealed three emerging themes i.e. the mobile banking app experiences and sustained usage of mobile banking apps are largely affected by consumers’ level of knowledge (consumer awareness), usefulnes…
