Procedural standards of participation have the capacity to structure and constrain the exercise of authority. Focusing on the way decisions are formed, this paper argues that the depletion of such standards in processes of reception of trans- and international decisions within the EU potentially leads to situations of unrestrained authority and can constitute a challenge to the rule of law. The first part of the paper identifies the conditions under which this may occur. It sets out the basis for a conceptual and normative analysis underpinning the argument that procedural standards of participation can be considered part of the rule of law. As such, the depletion of procedural standards emerges as one facet of a broader problem – the ability of public law to structure discretion and constrain the exercise of authority that results from internationalised procedures. These intertwined decisionmaking procedures cutting across different levels of governance challenge law’s ability to limit executive action and, hence, the rule of law premise that the exercise of public authority ought to be limited by law. In this way, and despite its EU focus, the paper contributes to analysing the challenges and possibilities of the rule of law in the current realities of diffusion of power resulting from internationalisation. This perspective requires a re-conceptualisation of the decision-making procedures that operate the substantive coordination between the sites of governance involved. The processes through which inter- and transnational rules and decisions are received in EU law are only segments of a broader regulatory cycle initiated by inter- and transnational bodies – of which the receiving authorities are either members, observers, or, otherwise active collaborating parties. Such processes can neither be fully grasped by focusing only on the segments of decision-making developed within each legal system, nor can the challenges they pose to law be apprehended from this perspective. They ought to be seen in their entirety as segments of a broader regulatory cycle. On this basis, the second part of the paper proposes two possible routes to rethink internationalised procedures [less ▲]

The European Communities (founded in 1951) with the ECSC and then the European Union started out as an exclusively west European enterprise. The guarantee of the “rule of law” was one of the criteria for accession to the European Union which the EU defined at the Copenhagen European Council in 1993, together with stability of institutions guaranteeing democracy, human rights, and respect for and protection of minorities. the existence of a functioning market economy as well as the capacity to cope with competitive pressure and market forces within the Union. Membership presupposes the candidate's ability to take on the obligations of membership including adherence to the aims of political, economic and monetary union. In their Constitutions today, all the countries of Central and East Europe confess to the “rule of law” as either a fundamental prerequisite or one of the highest values/a fundamental value of the constitutional order as stated (by Czech Republic, Slovakia, Slovenia, Poland), or by declaring their country operates under or is based on the “rule of law” as stated (by the Baltic countries, Hungary), or that it is a “law-governed state” as stated by (Bulgaria; Romania). In doing so, the countries confess to the “rule of law” at least in its formalistic understanding.The crucial question is what the “rule of law” as referred to by the EU in the Copenhagen Criteria and by the Constitutions of the countries of Central and Eastern Europe effectively means. What is the state practice? [less ▲]

A Rule-based Approach for Evolution of AADL Models based on Changes in Functional Requirements

in The workshop on Sustainable Architecture: Global Collaboration, Requirements, Analysis (SAGRA) at the 10th European Conference on Software Architecture (ECSA) (2016, November)

The increasing complexity of software systems makes change management costly and time consuming. To ensure the cost-effective system longevity and endurance, it is crucial to apply change management in the early stages of software development. In this paper, we introduce a rule-based approach to make software architecture evolving based on counter examples provided by a model checker for violated, changing functional requirements. The approach works on software architecture in AADL and is based on verifying functional requirements using Maude model checker. Our goal is to provide guidelines to the architect about potential changes. Using an industrial example, we show how our approach helps in determining changes to produce a new version of the architecture. [less ▲]

A Rule-based Contextual Reasoning Platform for Ambient Intelligence environments

The special characteristics and requirements of intelligent environments impose several challenges to the reasoning processes of Ambient Intelligence systems. Such systems must enable heterogeneous entities operating in open and dynamic environments to collectively rea- son with imperfect context information. Previously we introduced Con- textual Defeasible Logic (CDL) as a contextual reasoning model that addresses most of these challenges using the concepts of context, map- pings and contextual preferences. In this paper, we present a platform integrating CDL with Kevoree, a component-based software framework for Dynamically Adaptive Systems. We explain how the capabilities of Kevoree are exploited to overcome several technical issues, such as com- munication, information exchange and detection, and explain how the reasoning methods may be further extended. We illustrate our approach with a running example from Ambient Assisted Living. [less ▲]

Before performing a surface finishing process, human operators analyze the workpiece-conditions and react accordingly, i.e. they adapt the contact-situation of the tool with respect to the surface. This first step is ignored in most suggested automation concepts. Although their performance is satisfactory for the general process thanks to adaptive position- and force-/torque-control algorithms, they are unable to address specific problematic cases as often encountered in practice because of variations in workpiece-dimensions or -positioning. In this work, a human mimicking element is developed to overcome this limitation of current control concepts and to translate human expertise to the robotic manipulator. A rule-based system is designed where human knowledge is encoded as if-then rules. This system is integrated with a previously suggested control strategy in a hierarchical manner. The developed concept is experimentally validated on a KUKA LWR 4+-robotic manipulator. [less ▲]

Rules and mechanisms governing octahedral tilts in perovskites under pressure

The rotation of octahedra (octahedral tilting) is common in ABO(3) perovskites and relevant to many physical phenomena, ranging from electronic and magnetic properties, metal-insulator transitions to improper ferroelectricity. Hydrostatic pressure is an efficient way to tune and control octahedral tiltings. However, the pressure behavior of such tiltings can dramatically differ from one material to another, with the origins of such differences remaining controversial. In this paper we discover several new mechanisms and formulate a set of simple rules that allow us to understand how pressure affects oxygen octahedral tiltings via the use and analysis of first-principles results for a variety of compounds. Besides the known A-O interactions, we reveal that the interactions between specific B ions and oxygen ions contribute to the tilting instability. We explain the previously reported trend that the derivative of the oxygen octahedral tilting with respect to pressure (dR/dP) usually decreases with both the tolerance factor and the ionization state of the A ion by illustrating the key role of A-O interactions and their change under pressure. Furthermore, three new mechanisms/rules are discovered, namely that (i) the octahedral rotations in ABO(3) perovskites with empty low-lying d states on the B site are greatly enhanced by pressure, in order to lower the electronic kinetic energy; (ii) dR/dP is enhanced when the system possesses weak tilt instabilities, and (iii) for the most common phase exhibited by perovskites-the orthorhombic Pbnm state-the in-phase and antiphase octahedral rotations are not automatically both suppressed or both enhanced by the application of pressure because of a trilinear coupling between these two rotation types and an antipolar mode involving the A ions. We further predict that the polarization associated with the so-called hybrid improper ferroelectricity could be manipulated by hydrostatic pressure by indirectly controlling the amplitude of octahedral rotations.

In this survey paper we focus on some requirements for developing normative multi-agent systems (NMAS). In particular, we discuss Boella et al.’s guidelines proposed for NMAS. Finally, we deal with two more specific questions concerning the role of norms in rule-based NMAS: the concepts of compliance and norm change. [less ▲]
