Application of Zero Exclusion Condition to Stability Analysis of Computer Networks
2016
Stability, or robust [Dscr ]-stability analysis of computer network considered as a dynamic system, relies on increasing the speed of data transmission while minimizing the queuing time delays of its packets in the router buffers that can affect the overall data flow of the network traffic. We consider a zero exclusion condition as an effective method for testing and analyzing the computer networks stability. Our findings indicate that keeping control over the queuing time delays as well as including some factors of the RED algorithm and its variants, which we present in this paper, can improve the quality of network services significantly. Our method can be applicable both to single-loop a…
Energy efficient resource allocation in heterogeneous software defined network: A reverse combinatorial auction approach
2015
In this paper, resource allocation for energy effi- ciency in heterogeneous Software Defined Network (SDN) with multiple network service providers (NSPs) is studied. The considered problem is modeled as a reverse combinatorial auction game, which takes different quality of service (QoS) requirements into account. The heterogeneous network selection associated with power allocation problem is optimized by maximizing the energy efficiency of data transmission. By exploiting the properties of fractional programming, the resulting non-convex Winner Determination Problem (WDP) is transformed into an equivalent subtractive convex optimization problem. The proposed reverse combinatorial auction ga…
Społeczeństwa sieci a zróżnicowanie kulturowe. Socjologiczna analiza relacji
2017
The contemporary world can be characterized by the gradual increase in cultural diversity, which results from a variety of global processes. The shrinking of time and space brought together groups of people who represent a multitude of sometimes distant cultures. This cultural diversity is incorporated into the fabric of societies which operate at different levels of cultural development, including network societies. Thus, the aim of the following article is to present the relationship between cultural diversity and network society. In the first decades of the 21st century, our civilization experienced a huge technological revolution which led to an increase in the flow and volume of the tr…
Structural analysis of network models in tetrapod skulls : evolutionary trends and structural constraints in morphological complexity, integration an…
2013
Background Ever since classic anatomists like George Cuvier, Geoffroy St. Hilaire, or Richard Owen laid down the fundamental principles of comparative anatomy in the 19th century, connections among anatomical parts have been essential for the recognition of biological homologies. However, few studies have addressed the possibility of implementing an adequate methodological tool to use connections among parts to unveil problems in morphology; although Woodger, Rashevsky, Riedl, and, more recently, Rasskin-Gutman pointed in this direction. In the last decades Network Theory has been developed as a novel conceptual and methodological framework to deal with the relational properties that emerge…
Benefits and drawbacks of communication visibility : from vicarious learning and supplemental work to knowledge reuse and overload
2022
Purpose This study aims to examine some of the benefits and drawbacks of communication visibility. Specifically, building on communication visibility theory, the authors study how and why message transparency and network translucence may increase knowledge reuse and perceived overload through behavioral responses of vicarious learning and technology-assisted supplemental work. Design/methodology/approach Drawing on survey data obtained from 1,127 employees of a global company operating in the industrial machinery sector, the authors used structural equation modeling to test the hypothesized model. Findings The results demonstrate that the two aspects of communication visibility yield somew…
A critical re-examination of the academic literature on venture capital networks
2020
This paper proposes a critical re-examination of the recent trends of the literature on venture capital networks. This brief review thoroughly scrutinises three papers that are representative of the recent academic literature in this field of study. I identify their points of strength and limitations, in order to pave the way for future research. This paper shows that the study of network weak and informal ties and the role of risk management strategies are promising areas for pushing the frontiers of research on venture capital networks. Extending our knowledge on this topic is crucial to understand the best strategic decisions venture capital firms should take, as parts of an inter-organi…
MAKE LIFE EASIER ON CAMPUS WITH HIGH-SPEED NETWORK
2012
In this paper I have shown that with the evolution of technology, networks and the Internet have become an almost daily necessity, being an essential part of our individual, economic and social life. On their well-functioning depend our governmental, commercial and even personal activities. The modern information society is already a reality, which ignores frontiers which may pass any spatial or temporal limitations due to the communication system. Economy, politics and society today are based ever more on a computerized infrastructure.
Il rescaling e la flessibilità geografica del modello territoriale reticolare policentrico
2021
Con l’obiettivo di alimentare il dibattito scientifico-disciplinare in corso sulle modalità con cui i territoti devono essere governati e con quali strumenti e politiche, il contributo intende proporre alcune riflessioni sulle relazioni che stanno caratterizzando il processo evolutivo dei territori, sulle forme di cooperazione necessarie e sui confini che devono essere re-interpretati e ri-definiti, e propone il policentrismo reticolare come modello di sviluppo territoriale da perseguire per affrontare le sfide del rescaling. I primi due paragrafi affrontano specificatamente le questioni legate ai processi di rescaling e alle questioni ancora aperte relativamente alla governance territorial…
L’arcipelago territoriale delle Aree Interne: verso nuove forme di economia, società e sviluppo locale
2017
L’attuale fase di transizione dei modelli economici sta provocando fasi di instabilità, necessità di cambiamento/aggiornamento/adattamento nella sfera economica, nei processi di sviluppo e innovazione, nello stile di vita delle società e dei cittadini, nelle città e nei territori rurali. Questa instabilità si sta verificando sia nelle città sia nei territori interni caratterizzati da perdita demografica, elevato indice di invecchiamento e incapacità di soddisfare le nuove esigenze del mercato. Le Aree Interne rappresentano, pertanto, quei territori in cui un ripensamento del rapporto territorio/produzione nonché degli strumenti e delle politiche da attivare è sempre più impellente per la lo…
