In this paper we consider the computability of the solution of the initialvalue problem for differential inclusions with semicontinuous right-hand side. We present algorithms for the computation of the solution using the “ten thousand monkeys” approach, in which we generate all possible solution tubes, and then check which are valid. In this way, we show that the solution of an upper-semicontin...

the area of bargaining mechanisms has been well explored in both multi-agent systems and economics. in bargaining, participants raise/reduce their offers until an agreement is hopefully reached. in this dynamic environment, finding superior agreements without having the knowledge about the strategic private information of the counterpart is considerable. in this paper, we present a simple semi-...

the main of this research was to investigate the effect of a psychological training program on mental health of elite basketball players. this research was semi–experimental with pretest posttest and a control group. the population consisted of all basketball players from iran basketball super league (n=150). they were divided into two teams: experimental and control group. minnesota multiphasi...

The object of this paper is to analyse the sedimentologic characteristics of old and new terrace sediments from the Pawmpawm River channel. The morphometric characteristics of the terrace materials give credence to the hydrologic dynamics of the river as it performs its core functions of erosion, transportation and deposition with time. The terrace materials are evidenced from their petrographi...

We extend the model for semi-structured data proposed in [4], where both databases and schemas are represented as graphs, with the possibility of expressing different types of constraints on the nodes of the graphs, and defining queries which are used to select graphs from a database. We show that reasoning tasks at the basis of query optimization, such as schema subsumption, query-schema compa...

I N recent years, several notes in this journal have called attention to the distinctive wing-flashing of the Mockingbird (Mimus polyglottos) , in which the wings are opened upward at about 45” in a series of jerking movements, then closed. In this display, large white wing patches are exposed. The function of this behavior remains unknown; but, since the display is most frequently seen being p...

Plants and Insects are studied since decades, but, most of the time, separately. In Agronomy, plants are studied in order to improve crop yields while insects are studied in order to control their (negative or positive) impacts on crop yields. It is well known that plants and insects are always in interaction but, surprisingly, they are very few mathematical models of these interactions. For in...

The problem of modeling semi structured data is important in many application areas such as multimedia data management biolog ical databases digital libraries and data integration In this paper we base our work on bdfs which is a formal and elegant model for semi structured data where schemas are graphs whose edges are labeled with formulae of a theory T We extend bdfs with the possibility of e...
