Fiber optic sensor to detect nitrite and nitrate in water

Abstract: A fiber optic sensor prototype to detect nitride and nitrate in water is presented. Its working principle is based on a spectrophotometric technique, and makes use of specific chemical reagents.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

Decomposition of games: some strategic considerations

Abstract: Candogan et al. (2011) provide an orthogonal direct-sum decomposition of finite games into potential, harmonic and non-strategic components. In this paper we study the issue of decomposing games that are strategically equivalent from a game-theoretical point of view, for instance games obtained via duplications of strategies or suitable linear transformations of payoffs. We consider classes of decompositions and show when two decompositions of equivalent games are coherent.

Application of the X-ray laser to muon-catalyzed d-t fusion

Abstract: We discuss the alpha-muon sticking coefficient in the muon-catalysed d-t fusion in the framework of the Constrained Molecular Dynamics model. Especially the influence of muonic chaotic dynamics on the sticking coefficient is brought into focus. The chaotic motion of the muon affects not only the fusion cross section but also the muon-alpha sticking coefficient. Chaotic systems lead to lar ger enhancements with respect to regular systems because of the reduction of the tunneling region. Moreover they give smaller sticking probabilities than those of regular events. By utilizing a characteristic of the chaotic dynamics one can avoid losing the muon in the muCF cycle. W e propose that the application of the so-called microwave ionization of a Rydberg atom to the present case could lead to the enhancement of the reactivation process by using X-rays.

Reti strategiche come evoluzione delle reti emergenti: L'esperienza di due contratti di rete nel bresciano

Abstract: Purpose of the paper : Italian firms are increasingly drawn to modify their own competitive positioning. Traditional network relations, such as industrial districts or subcontracting value chains, are not themselves sufficient to generate this repositioning, since they are not designed to achieve a strategic goal, but tend to emerge spontaneously. We focus on an evolutionary path, empirically drawn from two case studies, leading to the definition of strategic network, i.e., an aggregation resulting from joint projects designed to manage the shift of partner firms towards an higher value-added segment of the value chain. Methodology : This paper analyzes the formal network contract as an empirical phenomenon capturing the theoretical concept of strategic network. It does so investigating the case of network contracts flourished in the area of Brescia. Findings : Strategic networks analyzed via two network contracts showed that different strategies exist to exploit value from the diversity of member firms; risks can arise from this diversity; risks can be tackled by means of proper governance mechanisms. Research limits : The analysis is focused on two representative cases. Undoubtedly, enriching this analysis with the observation of networks embedded in other areas would enhance and enrich the discussion raised in the article. Practical implications : The article analyzes the problems tackled, the strategies used, and the solutions selected by the network actors embedded in a “network-intensive area” (Brescia province). The idea is that these networks can act as a models for other entrepreneurs who want to build new networks or promote the existing ones. Originality of the study : The emergence of networks by means of formal network contracts remains largely unexplored. The analysis highlights the critical issues and the great potential of this instrument. Italian Obiettivo del paper : L’impresa italiana e chiamata a governare il proprio riposizionamento competitivo. Le aggregazioni reticolari tipiche dei nostri territori, come i distretti industriali o le filiere di subfornitura, non sono piu sufficienti a generare questo riposizionamento, poiche sono aggregazioni emergenti, non progettate strategicamente per raggiungere un obiettivo. Nell’articolo viene presentato un percorso evolutivo, empiricamente rappresentato da due casi studio, che porta alla definizione del concetto di rete strategica, vale a dire coscientemente disegnata per riposizionare le imprese che ne fanno parte in un segmento a piu alto valore aggiunto della catena del valore. Metodologia : Questo lavoro analizza il contratto di rete come fenomeno empirico che cattura il concetto teorico di rete strategica, approfondendo il caso di due contratti di rete stipulati nella provincia di Brescia. Risultati : Le reti strategiche analizzate tramite i due contratti di rete oggetti di analisi hanno permesso di capire come vi siano diverse strategie volte a mettere a valore la diversita delle compagini di imprese retiste, come questa diversita possa sollevare dei rischi, e come questi rischi possano essere affrontati con opportune scelte di governance. Limiti della ricerca : L’analisi si concentra su due casi emblematici. Sicuramente, l’ampliamento dell’analisi a reti presenti in territori diversi porterebbe ad una estensione ed arricchimento delle tematiche affrontate nell’articolo. Implicazioni pratiche : Nell’articolo vengono analizzati i problemi affrontati, le strategie messe in campo e le soluzioni scelte da imprenditori retisti localizzati in un’area “ad alta densita di reti” (l’area bresciana). L’idea e che possano fungere da modello per altri imprenditori che vogliano costituire nuove reti o promuovere l’evoluzione di quelle gia esistenti. Originalita del lavoro : La costruzione di reti a mezzo di contratti resta ancora largamente inesplorata. Nell’analisi, si evidenziano alcune criticita e contestualmente le enormi potenzialita dello strumento.
