the kind of contracts of government and public organisations that relates public affaires, that named public or administrative contracts , are very important to fulfil legal duties of government, and public contracts are new forms of providing public welfare, and management of public services, that are based on consenting instead of being authoritarian, but had been studied less in iran law bec...

Law information retrieval systems use law ontologies to represent semantic objects, to associate them with law documents and to make inferences about them. A number of law ontologies have been proposed in the literature, what shows the variety of approaches pointing to the need of matching systems. We present a proposal based on argumentation to match law ontologies, as an approach to be consid...

This paper presents an investigation of a radio receiver architecture to enable multi-standard (GPRS, WCDMA, HiperLAN2) implementation in mobile terminals. The architecture uses partial radio band digitisation at an intermediate frequency. Following circuit progress and industry trends (e.g. Moore’s law) we estimate components for the proposed architecture with acceptable power consumption to b...

the main purpose followed in this study was to identify and analyze the mechanisms of nanotechnology development in iranian agricultural sector. the research method was an analytical- explanatory one. the statistical population of the study consisted of researchers of national agricultural research institutions/ centers (n= 170). according to morgan& krejcie table, 120 persons were selected thr...

We present a new method to compute output gain-scheduled controllers for non-linear systems. We use structured H∞-control to pre-compute an optimal controller parametrization as a reference. We then propose three practical methods to implement a control law which has only an acceptable loss of performance with regard to the optimal reference law. Our method is demonstrated in longitudinal fligh...
