Simulation Platform For Invulnerability Of Industrial Wireless Sensor Networks, Xiuwen Fu, Yongsheng Yang

Journal of System Simulation

Abstract: Existing simulation platforms for industrial wireless sensor networks (IWSNs) mainly focus on the general scenario and fail to take into consideration the impacts of interference brought by external environments and emergencies on network performance, thus failing to evaluate the network invulnerability. For given the environment-impacted and event-driven features of IWSNs, the connections between network invulnerability and deployment environment are built. On this basis, a simulation platform for invulnerability of IWSNs is proposed by introducing deployment environment component and event creator. Experiments show that the platform is capable of evaluating the invulnerability of IWSNs.

The Polish Leniency Programme And The Implementation Of The Ecn+ Directive Leniency-Related Standards In Poland, Patrycja Szot

Yearbook of Antitrust and Regulatory Studies

This publication discusses the current state of the Polish leniency programme and the amendments required in order to implement the ECN+ Directive (in particular in the area of specific conditions for leniency, individual sanctions, protection of leniency statements or leniency plus) as well as harmonisation flaws (primarily lack of one-stop-shop, universal language, failure to lay down rules regulating the reduction of fines or fully coordinating rules on immunity from individual sanctions, lack of harmonisation regarding applications in non-cartel cases). The author’s view is that the Polish system in broad terms corresponds to the majority of the harmonised standards owing to …

The Implementation Of The Ecn+ Directive In Hungary And Lessons Beyond, Katalin J. Cseres

Yearbook of Antitrust and Regulatory Studies

In order to facilitate national competition authorities (NCAs) in their application of EU competition rules, the EU legislator adopted Directive 2019/1/EU. The Directive’s aim is to empower the competition authorities of the Member States to be more effective enforcers of competition law and to ensure the proper functioning of the internal market. The so-called ECN+ Directive introduces minimum harmonisation rules allowing competition authorities to have common investigative, decision-making (notably fining decisions) and enforcement powers. The Directive, furthermore, sets minimum safeguards for the NCAs’ independence, accountability and resources as well as harmonizes leniency programmes including the coordination of national leniency programmes …

New Scenarios Of The Right Of Defence Following Directive 1/2019, Marialaura Rea

Yearbook of Antitrust and Regulatory Studies

The purpose of this paper is to analyze the effects of Article 3 of Directive 1/2019 when transposing it by Member States. The incompleteness and vagueness of Article 3 of Directive 2019/1 could cause non-harmonization in the various EU Member States, especially those in Eastern Europe, of the right of defence for the defendant party in the antitrust procedure. More specifically, to avoid this effect, Member States must adapt to European standards. In doing so, the paper intends to shed some light on how the right of defence is protected by the European Commission during competition proceedings.

Competition Law Enforcement In Italy After The Ecn+ Directive: The Difficult Balance Between Effectiveness And Over-Enforcement, Giacomo Dalla Valentina

Yearbook of Antitrust and Regulatory Studies

Almost fifteen years after its adoption, the system of decentralized enforcement laid down in Regulation 1/2003 has shaped competition law in a way that could hardly be predicted, in terms of both magnitude and quality of the activities of National Competition Authorities. More recently, the so-called ‘ECN+ Directive’ was adopted to address the shortcoming of such system, namely a perceived lack of independence and accountability of several NCAs and a certain degree of divergence within the European Competition Network. In this scenario, the Italian Competition Authority has frequently been depicted as a well-equipped, independent and effective enforcer and – with …

Cumulative Enforcement Of European And National Competition Law And The Ne Bis In Idem Principle Case Comment To The Judgement Of Eu Court Of Justice Of 3 April 2019 Powszechny Zakład Ubezpieczeń Na Życie S.A. V Prezes Urzędu Ochrony Konkurencji I Konsumentów (Case C-617/17), Mario Libertini

Yearbook of Antitrust and Regulatory Studies

The judgement of EU Court of Justice in response to the request for a preliminary ruling by the Polish Supreme Court confirms that the principle of ne bis in idem, enshrined in Article 50 of the Charter of Fundamental Rights of the European Union, must be interpreted as not precluding a national competition authority from fining an undertaking in a single decision for an infringement of national competition law and for an infringement of Article 82 EC (now Article 102 TFEU). In that regard it can be concluded that the judgement does not have anything new and is just a …
