Sapieżyńska ochrona dóbr Potockich w starostwie owruckim w latach 80. i 90. XVII wieku Przyczynek do badań nad współpracą rodzin magnackich w czasach…
2019
The Sapiehas and the Potockis were amongst the most influential families of the Polish‑Lithuanian Commonwealth. The latter family owned numerous estates in Ukraine, which were directly under threat from marching Lithuanian soldiers. Kazimierz Jan Sapieha, Grand Hetman of Lithuania was in charge of the said estates. Due to cooperation of the two magnate families, he attempted to shield the Potockis’ estates and possessions from Lithuanian troops marching to or returning from the war with Turkey. To that aim he utilised legal proclamations called Universals. The Potockis returned the favour by entering into political collaboration. Hetman Kazimierz Jan Sapieha, having been absent from the Sie…
The Other J.M.: John Maurice Clark and the Keynesian Revolution
2009
This paper suggests that Clark's views regarding the Keynesian Revolution illuminate some of the limitations of the Keynesian orthodoxy that developed after the war, bringing more institutional detail and a greater preoccupation with dynamic analysis. Clark developed the multiplier in dynamic terms and coupled it with the accelerator to provide the framework for business cycle theory. His analysis was not formalized and emphasized time lags and non-linearities, similar to Harrod. In addition, Clark was concerned with the inflationary consequences of Keynesian policies and he was dissatisfied with those mechanical interpretations of the income flow analysis, which came to be known as hydraul…
Geochemical constraints on basalt petrogenesis in the Strait of Sicily Rift Zone (Italy): Insights into the importance of short lengthscale mantle he…
2020
Igneous activity from the late Miocene to historic time (most recently 1891 CE) in the Strait of Sicily has created two volcanic islands (Pantelleria and Linosa) and several seamounts. These volcanoes are dominated by transitional (ol + hy-normative) to alkaline (ne-normative) basaltic lavas and scoriae; volcanic felsic rocks (peralkaline trachyte-rhyolite) crop out only on Pantelleria. Although most likely erupted through continental crust, basalts demonstrate no evidence of crustal contamination and are geochemically similar to oceanic island basalts (OIB). Despite their isotopic similarities, there are considerable compositional differences with respect to major and trace element geochem…
Multimode WSN: Improving Robustness, Fault Tolerance and Performance of Randomly Deployed Wireless Sensor Network
2010
This paper proposes an advanced, robust and flexible solution that applies the (revised) concept of Always Best Connected (ABC) Network, typical of multimode modern mobile devices, to Wireless Sensor Network. Hostile environments and unpredictable conditions (e.g. interferences) can negatively affect communication range, potentially increasing the number of unconnected nodes in random deployments. Multimode Wireless Sensor Network (MM-WSN) is provided with an adaptive mechanism for environmental condition evaluation and with the ability of self-configuring itself for optimal networking independence of detected conditions. Proposed solution is based on advanced smart nodes provided with mult…
Q-Chem 2.0: a high-performanceab initio electronic structure program package
2000
ABSTRACT: Q-Chem 2.0 is a new release of an electronic structure programpackage, capable of performing first principles calculations on the ground andexcited states of molecules using both density functional theory and wavefunction-based methods. A review of the technical features contained withinQ-Chem 2.0 is presented. This article contains brief descriptive discussions of thekey physical features of all new algorithms and theoretical models, together withsample calculations that illustrate their performance. c 2000 John Wiley S electronic structure; density functional theory;computer program; computational chemistry Introduction A reader glancing casually at this article mightsuspect on t…
The role of sport-specific play and practice during childhood in the development of adolescent Finnish team sport athletes
2016
This study sought to understand the role of sport-specific play and practice in the development of adolescent team sport athletes in the Finnish sports development system. Participants were male, 15-year-old soccer (n = 141), ice hockey (n = 204), and basketball (n = 96) players, divided into three groups based on the amount of sport-specific play and practice experienced during childhood. Data were collected with sport-specific inventories of practice history, tactical skills, psychological skills, and sport-specific skill test. Results showed that athletes with more sport-specific play and practice during childhood had more sport-specific play and practice during adolescence, better techn…
Personal Reasons for Withdrawal from Team Sports and the Influence of Significant others among Youth Athletes
2013
The aim of this study was to identify the main reasons for withdrawal from team sports and to examine the influence of significant others (i.e., coaches, parents, peers, and siblings) in the decision making concerning withdrawal from youth sports. An attempt was also made to compare withdrawal components and the influence of significant others in terms of gender, level of competition and years of involvement in youth sports. The participants in this study were young football (American soccer) (n=397), ice hockey (n=88) and basketball (n=50) players who had terminated their participation in their sports. Principal component analysis was used to reduce the number of withdrawal items and iden…
A method for modeling the battery state of charge in wireless sensor networks
2015
In this paper we propose a method for obtaining an analytic model of the battery State-of-Charge (SoC) in wireless sensor nodes. The objective is to find simple models that can be used to estimate accurately the real battery state and consequently the node lifetime. Running the model in the network nodes, we can provide the motes with the required information to implement applications that can be considered as battery-aware. The proposed methodology reduces the computational complexity of the model avoiding complicated electrochemical simulations and treating the battery as an unknown system with an output that can be predicted using simple mathematical models. At a first stage, during a se…
Electric Vehicles and Psychology, Part 2
2021
This paper presents the main psychological attitudes influencing the transition from conventional ICEV to BEV, and it is the continuance of Electric vehicles and psychology, part 1, [1]. This part faces the range anxiety problem, the risk of explosion of batteries, the autonomous silver vehicles and the experience of driving electric vehicles. If the reader is looking for simple answers, the author does not recommend the subsequent reading, since few paradoxes will be solved.
A Comprehensive Survey on Cooperative Relaying and Jamming Strategies for Physical Layer Security
2019
Physical layer security (PLS) has been extensively explored as an alternative to conventional cryptographic schemes for securing wireless links. Many studies have shown that the cooperation between the legitimate nodes of a network can significantly enhance their secret communications performance, relative to the noncooperative case. Motivated by the importance of this class of PLS systems, this paper provides a comprehensive survey of the recent works on cooperative relaying and jamming techniques for securing wireless transmissions against eavesdropping nodes, which attempt to intercept the transmissions. First, it provides a in-depth overview of various secure relaying strategies and sch…
