TL;DR: In this article, a model on this theme is developed, on the lines of one of Professor Ballestero's research programmes, for the organisation of crop reception periods. But there is a notable lack of models of the operation of a crop reception period, which study the relationships between the effects of a waiting phenomenon and the effect of a system of premiums for farmers designed to stimulate them to deliver their crops.
Abstract: In the literature on agricultural economics there are several applications of the classic models of the theory of queues in agricultural production processes. However, there is a notable lack of models of the organisation of crop reception periods which study the relationships between the effects of a waiting phenomenon and the effects of a system of premiums for farmers designed to stimulate them to deliver their crops in a period of time fixed beforehand. In this paper a model on this theme is developed, on the lines of one of Professor Ballestero's research programmes.

PRIME OPTIMALE DANS LA LIVRAISON DES RECOLTES
La litterature des sciences economiques agricoles renferme plusieurs applications des modeles classiques de la theorie des files d'attente dans l'achemiment de la production agricole. Pourtant, l'on constate une serieuse absence de modeles de l'organisation des periodes de reception des recoltes pour etudier la relation entre les effets d'un phenomene d'attente et les effets d'un systeme de primes aux producteurs destinea leur fournir des stimulations les incitant a livrer leurs recoltes dans un laps de temps fixe d'avance. Cet article fait la description d'un modele sur ce theme, inspire d'un des programmes de recherche duprofesseur Ballestero.
Zusammenfassung
OPTIMALE PRAMIE BEZUGLICH ERNTEUBERGABE
In Schriftstucken uber Agrarwirtschaft gibt es mehrere Anwen-dungen der klassischen Modelle der Theorie des Warteprozesses. Es herrscht jedoch ein bemerkenswerter Mangel an Modellen in der Organisation von Ernteubergabezeiten. Diese Modelle untersuchen die Beziehungen zwischen den Folgen eines Wartephanomens und denen eines Pramiensystems, das Landwirte zur Abgabe ihrer Ernten binnen im voraus festgelegten Zeitspannen anregen soll. In dieser Abhandlung wird ein Modell auf dieses Thema aufgebaut im Sinne eines der Forschungsprogramme des Herrn Professor Ballestero geschrieben.
TL;DR: In this article, the stability of the nearly uniform distribution of the current through the junction of the diode is analyzed and it is concluded that, for diodes which are small enough, a hot point cannot appear.
Abstract: This paper discusses the process of the generation of hot points in reverse biased p−n diodes. In this work we use a simple lumped thermal model of the diode. The stability of the nearly uniform distribution of the current through the junction of the diode is analysed. This analysis determines, for every diode, the maximum value of the current under which the junction will be free of current constriction, or hot points. It is concluded that, for diodes which are small enough, a hot point cannot appear. Nevertheless, if a nearly ideal voltage generator is used to drive the diode, a thermal instability of the whole junction can appear.
