    Апробація методу контролю акустичної емісії для дослідження структурних змін у водних розчинах
    (Видавництво Національного університету «Львівська політехніка», 2009) Пташник, Вадим; Януш, Ярослав; Прилєпська, Світлана
    In the given paper the aspects of application of acoustic emission method are used to research structural changes in water solutions the processes of melting and crystallization of water were researched by us with application of device, that consists of acoustic emission sensor and metallic cup for the explored specimen. Universality and high sensitivity of acoustic emission method allows us to use it for research physical and chemical processes in a liquid environment (as the base/precursor of changes in phase transition processes).

    Дослідження електроенергетичних систем на основі діакоптичного підходу та макромоделювання в сучасних комп’ютерних середовишах
    (Видавництво Національного університету «Львівська політехніка», 2009) Гоголюк, Оксана; Корецький, Роман; Пташник, Вадим
    In the paper problems of mathematical modeling of electric power systems using modern computer environments based on macromodeling and diakoptic principles and prospects of their research on uni- and multiprocessor computers are discussed. The question of electric power systems splitting on several parts with the purpose of their further analysis by means of parallel processing and development of corresponding parallel algorithms, possibility and expediency of available computer tools usage for their practical implementation are considered.

    Електрохімічна активація водних розчинів як екологічний метод водопідготовки
    (Видавництво Львівської політехніки, 2013) Пташник, Вадим; Наконечна, Ольга; Велигорська, Мар’яна; Садова, Марія
    The possibility of using electrochemical activation of water as a method which can solve a number of complex environmental problems is shown in this work. An attempt to systematize and analyze existing applications of electrochemical activation of water and aqueous solutions is implemented. In purpose of total or partial replacement a number of dangerous technological operations, it is offered examples of using functional solutions based on electrochemically activated water. The possibility of natural water purification and waste water purification from certain pollutants by using electrochemical activation is considered in work. Separately it is investigated the mechanisms of biological effects of electrochemically activated solutions for livelihoods process of biota.
