Intrathoracic displacement of the humeral head is a very uncommon condition and can be life threatening due to lungor heart injuries. There is a report of this condition where intrathoracic bone fragment was missed. Because of rareincidence there is no guideline for approach and treatment of this condition.We hereby present a case of intrathoracic displacement of fractured hum...

The purpose of the article is to define metamorphosis in Ukrainian ornamentation based on principles gradualism and punctualism, which allows us determine evolutionary gradual approach due mimesis discrete according poiesis. research methodology methods semiotic epistemological analysis, system-analytical comparative-historical methods. method has been used philosophical meaning symbols pattern...

Metric Temporal Logic (MTL) and Timed Propositional (TPTL) are prominent real-time extensions of Linear (LTL). In general, the satisfiability checking problem for these is undecidable when both future (Until, U) past (Since, S) modalities used (denoted by MTL[U,S] TPTL[U,S]). a classical result, Interval (MITL[U,S]), non-punctual fragment MTL[U,S], shown to be decidable with EXPSPACE complete c...

Railway track maintenance and renewal are vital for railway safety, train punctuality, travel comfort. Therefore, having cost-effective is critical in managing infrastructure assets. There has been a considerable amount of research performed on mathematical decision support models improving the application planning scheduling. This article reviews literature scheduling transforms results into p...

Performance aspects such as travel time, punctuality, and robustness are conflicting goals of utmost importance for railway transports. To successfully plan traffic, it is therefore important to strike a balance between planned times expected delays. In operations research, lot attention has been given construct models methods generate robust timetables—that is, timetables with the potential wi...

Train operation control is of great importance in reducing train energy consumption and improving railway efficiency. This paper investigates the design optimal inputs for multiple trains on a single line with several stations. Firstly, distributed problem formulated to reduce improve punctuality trains. Then, we propose an efficient algorithm based framework symmetric alternating direction met...

This article presents an ant colony optimization for the time scheduling of public transport traffic. In fact, the assistance of a decision support system becomes necessary for the real-time regulation of this transport networks since the size of the search space increases exponentially with the number of vehicles and stops. So, we propose an ant colony algorithm with dynamic local search, in t...

timents, and shews that the zeal of improvement may sometimes, even in the best concerns, be carried beyond the bounds of discretion, and that regulations and institutions, which we may think evil or unnecessary, may be both salutary and advisable. " The observance of fasts is a wholesome form of superstition. The omission of them in the Protestant calender, was, perhaps, as it relates to healt...
