OPTOELECTRONIC DEVICES APPLICATION FOR FOREST SEEDS SEPARATION

With the development of optoelectronic technologies, it became possible to use a qualitative criterion for seed separation – their spectrometric properties, reflecting the degree of viability and germination. In the detection system of optoelectronic devices, it is possible to achieve a complete absence of mechanical interaction with the seed.

AN ATTEMPT TOWARDS A MODEL APPROACH TO CHOOSING A STOCK REPLENISHMENT SYSTEM UNDER CONDITIONS OF INDEPENDENT DEMAND

The premise for approaching the subject is the need to support companies in selecting the best stock replenishment system, taking into account all external or internal limitations related to delivery terms and order volumes assuming that safety stock is the central factor ensuring the achievement of the intended availability level. In order to meet the objective, several stock replenishment systems are briefly described. Then, prerequisites for their proper selection are identified and classified. As a result, a selection table is developed along with an algorithm for selecting an optimal stock replenishment system based on an economic or qualitative criterion.

Subliminale Modernität

Is self-reflexivity, as is often maintained, a structural characteristic of literary modernity? To what extent does self-reflexivity provide a specifically modern as well as qualitative criterion which helps to distinguish between aesthetically experimental texts and less advanced ones? Proceeding from a problematization of the concept of modernity, I explore these questions with reference to E.T.H. Hofmann‘s Prinzessin Brambilla. Labelled a ‚Capriccio,‘ the narrative unfolds as an arabesque, in which subjectivity and textuality constitute each other, so that personal as well as semantic identity appear to be multiple. Just as the mythic ‚mirror brightness‘ of the well Udar releases from the constraint of being identical with oneself by transfiguring the „I“ into a reflexive medium of alterity which is sensually perceivable, so the narrative dynamics of the text lead one to produce a reading of it as a figuration of transgression. The thematic analysis leads to a transgression of self-reflexivity, which – on the level of form – is made comprehensible as a narratological transgression. The pluralisation of the I, which is narratively staged through the mirroring of the main character in others, corresponds also with the theatrical self-image of the actor. All in all it is evident that Hoffmann’s narrating en abîme organizes a dimension of the aesthetics of the text as well as of its reception, in which the literary dissolution of the Self gives way to reflexions of reading devoid of a subject. The innovative aspect of this study is the insight it provides into the dynamics of transgression inherent to the binarity of self-reflexivity. Only a poetologically transgressive self-reflexivity qualifies it to be a distinguishing criterion of literary modernity. In taking the aesthetic structures of subjectivity to the threshhold of their deconstitution, this poetically configured subliminality conveys a specifically modern sense of crisis.

Qualitative criterion for interception in a pursuit/evasion game

A qualitative account is given of a differential pursuit/evasion game. A criterion for the existence of an intercept solution is obtained using future cones that contain all attainable trajectories of target or interceptor originating from an initial position. A sufficient and necessary conditon that an opportunity to intercept always exists is that, after some initial time, the future cone of the target be contained within the future cone of the interceptor. The sufficient condition may be regarded as a kind of Nash equilibrium.
