Age of Information Based URLLC-enabled UAV Wireless Communications System
2022
This paper considers an unmanned aerial vehicles (UAV) communication network, where UAV operate as an aerial mobile relay between a source and a destination of the network. To capture the “timelines” of the received information at the destination node, a new performance metric named age of information (AoI) is considered. In addition, a short packet communication scheme maintains low latency in the proposed UAV wireless communication system. The finite block-length theory investigates the performances of short packet communications scheme in the UAV-assisted wireless communications system. In this paper, the Average Age of Information (AAoI) is estimated by applying the Stochastic Hybrid Sy…
Supportive Communication in the Workplace
2019
Supportive communication is a form of social interaction that produces resources with which to solve situational problems and manage emotional strain. Through the management of uncertainty, supportive communication enhances the perception of personal control over life events and strengthens the perception of acceptance. It is enacted in the seeking of support, in providing support, and in supportive listening as a form of emotional and informational support. In the workplace, supportive communication is crucially important: It promotes productive work and employees’ well-being as well as job satisfaction and engagement in the organization. This chapter presents the foundations of supportive…
Compensation of Nonlinearity of Voltage and Current Instrument Transformers
2019
This paper aims at characterizing and improving the metrological performances of current and voltage instrument transformers (CTs and VTs) in harmonic measurements in the power system. A theoretical analysis is carried out to demonstrate that, due to the iron core nonlinearity, CT and VT output signal is distorted even when the input signal is a pure sine wave. Starting from this analysis, a new method for CT and VT characterization and compensation is proposed. In a first step, they are characterized in sinusoidal conditions and the harmonic phasors of the distorted output are measured; in the second step, these phasors are used to compensate the harmonic phasors measured in normal operati…
A Computationally Efficient Online/Offline Signature Scheme for Underwater Wireless Sensor Networks
2022
Underwater wireless sensor networks (UWSNs) have emerged as the most widely used wireless network infrastructure in many applications. Sensing nodes are frequently deployed in hostile aquatic environments in order to collect data on resources that are severely limited in terms of transmission time and bandwidth. Since underwater information is very sensitive and unique, the authentication of users is very important to access the data and information. UWSNs have unique communication and computation needs that are not met by the existing digital signature techniques. As a result, a lightweight signature scheme is required to meet the communication and computation requirements. In this researc…
Reconfiguration de l'ordre mondial de l'information et de la communication: implications et incidences de la chaine Al Jazira
2014
Reconfiguración del orden mundial de la información y de la comunicación: implicaciones e incidencias de la cadena Al Yazira La información es la base de la toma de decisión. Los gobiernos a través de la Historia entendieron la influencia de este soft power en su política interior como exterior. Los Estados nacidos de la descolonización notaron sobre todo el desequilibrio de sus fuentes y sus consecuencias en términos de dominación cultural e intelectual. Esta tesis entonces pregunta cómo dar una voz al « Sur ». Analiza el enfoque de los principales actores implicados en el ideal de un « Nuevo orden mundial de la información y de la comunicación »: el Movimiento de los No-alineados y la UNE…
W sprawie potrzeby uregulowania umowy franczyzy w Polsce
2021
Praca prezentuje w pierwszej kolejności zagadnienia związane z pojęciem umowy franczyzy jako empirycznym typem umowy, jak i teoretyczne zagadnienie problematyki umów nienazwanych. W kontekście treści stosunku prawnego franczyzy zwrócono uwagę na dwie kwestie. Po pierwsze, pomimo braku regulacji umowy franczyzy w polskim prawie cywilnym wpływ na treść stosunku prawnego franczyzy mają przepisy prawa publicznego z zakresu ochrony konkurencji (prawa antymonopolowego). Wpływ ten należy ocenić jako istotny. Ewentualne uregulowanie w prawie cywilnym umowy franczyzy nie będzie oznaczało dopuszczalności pominięcia przy nadawaniu jej konkretnej treści regulacji prawa ochrony konkurencji. Po drugie, t…
Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.
2014
Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…

Uniformly Path Connected Homogeneous Continua
2016
It is proven that every path connected homogeneous continuum is uniformly path connected, which answers a question of David P. Bellamy. From this result it follows that every path connected homogeneous continuum is continuously equivalent either to an arc, or to the Cantor fan.
