Не зважаючи на широке використання технології розподілених децентралізованих реєстрів, зокрема в популярних платформах Bitcoin і Etherium, їм притаманні суттєві недоліки. Головним з них є невисока швидкість обробки транзакцій. Для його усунення цій роботі запропоновано двошарову модель розподіленого деценталізованого реєстру, що дозволить не тільки підвищити транзакцій, а й збільшити масштабова...

The gallides HfCoGa2 and HfNiGa2 were synthesized by arc-melting of the elements and subsequent annealing in glassy carbon crucibles. Their structures have been reinvestigated by X-ray diffraction on powders and single crystals: I4mm, a = 1222.4(1), c = 812.0(1) pm, wR2 = 0.0766, 1464 F2 values, 64 variables, BASF = 0.41(2) for HfCoGa2 and a = 1224.0(2), c = 809.3(2) pm, wR2 = 0.0609, 1499 F2 v...

Важливою складовою розв’язання проблеми децентралізованої координації керування розподіленими кібер-фізичними системами (РКФС) є отримання первинної інформації, яка необхідна для пошуку оптимального керування. Таку інформацію можна розділити на умовно постійну – параметри об’єкта керування, і змінну стан Визначення параметрів здійснюється шляхом задачі ідентифікації. Інерційність і, відповідно,...

Abstract Background Bearing dislocation is a problem following mobile bearing Oxford lateral Unicompartmental Knee Replacement (UKR). Therefore, the design of tibial component was changed from flat surface to domed with biconcave increase entrapment. This systematic review compared and revision rates two designs. Methods Two authors independently searched MEDLINE, EMBASE ISI Web Science, refere...

TECHNIQUE The Lyon Schuss view (an anteroposterior weight-bearing radiograph taken with the knee in 20–30 degrees flexion) offers greater accuracy in determining moderate to severe loss of joint space compared with the standard weight-bearing view with the knee fully extended3,4. This is particularly so in lateral compartment arthritis where the pattern of disease is different, ie the posterior...

AbstractBackground Cementless fixation is an alternative to cemented unicompartmental knee replacement (UKR). The aim of this study was determine if cementless UKR as good by comparing the five-year migration measured radiostereometric analysis (RSA) in a randomised controlled trial. Methods Thirty-nine patients were receive either or Oxford and studied at intervals u...

Inhomogeneous multidimensional cosmological models with a higher dimensional spacetime manifold M = M0 × ∏n i=1 Mi (n ≥ 1) are investigated under dimensional reduction to tensor-multi-scalar theories. In the Einstein conformal frame, these theories take the shape of a flat σ-model. For the singular case where M0 is 2-dimensional, the dimensional reduction to dilaton gravity is preformed with di...
