Item Electronic psychrometer based on August-Assmann method(Видавництво Національного університету “Львівська політехніка”, 2003) Proszak, W.; Proszak, D.; Hotra, O.; Melnyk, O.Наведено результати розробки, моделювання та описано функціонування електронного психрометра на основі методу Огуста–Асмана. The design, modelling and operation of electronic psychrometer based on August-Assmann method are considered at the paper.Item Relation between domain structure distortion and electric permeability and spontaneous polarisation in l-lysine doped tgs single crystals(Видавництво Національного університету "Львівська політехніка", 2004) Trybus, M.; Proszak, W.Researches upon relation between domain structure and electric properties of ferroelectric TGS doped single crystals are presented in this paper. Finding such relation should make possible elaboration of simplified method of samples preselection, that should be very convenient from the point of view of its application in fabrication of active elements of pyroelectric detectors. Possibility of finding such relation includes directly from theoretical model constructed by authors.Item Sensivity and average temperature of latgs pyroelectric detector(Видавництво Національного університету "Львівська політехніка", 2004) Proszak, W.New obtained single crystal LATGS and its selected dielectric properties are presented in this paper. Samples of the single crystal were utilised as active elements of pyroelectric detector. This paper contains also theoretical considerations for this type of detector, making possible determination of voltage-current sensitivity.
