The event-driven communication paradigm is used increasingly often to build loosely-coupled distributed systems in many industry domains including telecommunications, transportation, and supply chain management. However, the loose coupling of components in such systems makes it hard for developers to estimate their behaviour and performance under load. Most general purpose performance meta-mode...

The aim of this paper is twofold. First, it discusses how the functioning and performance of food chains are affected by the way stakeholders are embedded in the chains, by the coordination modes, and by the kind of governance. Second, by depicting six relevant agro-food chains, attention is raised on the kind of the stakeholders that participate in the chain and on the role of each with a spec...

We investigate the phase diagram of antiferromagnetic spin ladders with additional exchange interactions on diagonal bonds by variational and numerical methods. These generalized spin ladders interpolate smoothly between the S = 1/2 chain with competing nn and nnn interactions, the S = 1/2 chain with alternating exchange and the antiferromagnetic S = 1 chain. The Majumdar-Ghosh ground states ar...

The performance assessment of supply chains including sustainability dimensions of economic, environmental and social is a significant aspect for managers and decision makers. Furthermore, imprecise data are presented in many real world applications. Therefore, the current paper proposes an approach based on data envelopment analysis (DEA) to analyze the revenue efficiency of sustainable supply...

This paper presents a dual-objective facility programming model for a green supply chain network. The main objectives of the presented model are minimizing overall expenditure and negative environmental impacts of the supply chain. This study contributes to the existing literature by incorporating uncertainty in customer demand, suppliers, production, and casting capacity. An industrial case st...

Cybercrime today is a profit-driven enterprise. Viewing computer security through the lens of business incentives in this way helps guide the efforts of policy-makers and researchers, since the effectiveness of countermeasures is directly related to their effect on cybercriminals’ profit motives, the root causes of cybercrime. In this respect, understanding the structure of the cybercrime marke...

tthe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. this paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. as a novelty, the proposed controller employs a simple gaussian radial-basis-function network as an uncertainty estimator. the proposed netw...

this study investigates the conceptual metaphors of happiness in a representative corpus of modern persian. making use of persian linguistic database, we sampled a corpus of contemporary written texts, to represent modern colloquial persian; then we tried to extract the relevant conceptual metaphors of happiness. the sample corpus contains 14 texts written by contemporary iranian writers. analy...
