Weighted automata are non-deterministic automata where the transitions are equipped with weights.... more Weighted automata are non-deterministic automata where the transitions are equipped with weights. They can model quantitative aspects of systems like costs or energy consumption. The value of a run can be computed, for example, as the maximum, limit average, or discounted sum of transition weights. In multi-weighted automata, transitions carry several weights and can model, for example, the ratio between rewards and costs, or the efficiency of use of a primary resource under some upper bound constraint on a secondary resource. Here, we introduce a general model for multi-weighted automata as well as a multiweighted MSO logic. In our main results, we show that this multi-weighted MSO logic and multi-weighted automata are expressively equivalent both for finite and infinite words. The translation process is effective, leading to decidability results for our multi-weighted MSO logic.
Equality and Equity, prime principles of justice in creation and distribution of income and asset... more Equality and Equity, prime principles of justice in creation and distribution of income and assets, have plural, circular and retroactive relationships with globalization, growth and poverty. The objective of this paper is to establish a notion that which of these principles is to be followed and by which institutions in order to tackle the despicable stigma of poverty. In this aim, the first section of paper presents critical evaluation of equity vs. equality debate, specifically focusing on the processes of creation and distribution of outcomes and opportunities. The second section draws on the relative significance of institutions, principally government and IFIs, in these processes in order to spur growth, equality and wellbeing. This follows to the third section exhibiting some policy implications and recommendations. The paper concludes that no particular form of institution or principle of justice is 'panacea' to social and economic objectives, including reducing wide inequalities.

To realize this ambition substantial CO 2 savings have to be realized at the 375,000 current houses in the city. A special challenge is formed by the houses of historic and visual importance, as the implementation of standard energy saving measures may conflict with the ambition to protect their cultural and historic values. Nyenrode Business University was asked to study the possibilities for a successful combination of ambitions in both fields. This article shows an overview of suggestions that focus on the combination of technical and process orientated innovations which can contribute to the acceleration of the reduction of CO 2 emissions in houses of historic and visual importance. The article therefore addresses political and technical as well as financial and process related aspects in implementing energy saving measures in this category of buildings.
