The work uses a mathematical model for determining the frontal air resistance to movement of projectile, which based on solving inverse problem dynamics. Knowing flight range at certain angles aiming given in firing tables, functional dependence force projectile its speed and other factors is determined, taking into account effect weight Coriolis force.
 It has been established that, depen...

te c h o p s D irected Energy Weapons (DEW) have been a recurring theme in science fiction literature and cinema ever since H.G. Wells published the ‘War of the Worlds’ in 1898. The idea of a ‘death ray’ that can instantly destroy or burn a target at a distance retains its allure to this very day. More than a century after Wells contrived his ‘heat ray’ the technology is maturing to the point o...

A 5-day-old female neonate presented with persistent non-bilious projectile vomiting since birth. Baby girl was born at term by normal vaginal delivery. Antenatal scans at 12 and 20 weeks of pregnancy were reported as normal. Mother had polyhydramnios in late pregnancy. Baby was discharged home the same day of birth. The baby however developed non-bilious projectile emesis on the same day after...

Breakup calculations of loosely bound nuclei (B and Be) are performed with two different descriptions of the projectile. The descriptions differ strongly in the interior of the wave function, but exhibit identical asymptotic properties (ANC, and phase shifts). Calculations are performed for both nuclei at intermediate (40–70 MeV/nucleon) and low (26 MeV) energies with heavy and light targets. N...

A new heuristic optimization algorithm is presented based on an analogy with the physical phenomenon of a projectile launched in a conformational space under the influence of a gravitational force. Its implementation simplicity and the option to enhance it with local search methods make it ideal for the optimization of non-linear systems of equations. The algorithm is applied to standard test c...

A 20-day-old girl presented with increasing projectile vomiting over a period of one week and progressive weight loss. The diagnosis of hypertrophic pyloric stenosis (HPS) was made by sonography (Length of pyloric channel: 22 mm; muscle thickness: 5 mm). Open standard pyloromyotomy was performed. The postoperative course uneventful. On the 50th postoperative day, the girl was readmitted with pr...

A single-stage, sensor less, coil gun was designed to demonstrate the capability to accelerate a ferromagnetic projectile to high velocity. This paper summarize all important steps during coil gun design, such as physical laws of the coil gun, preliminary calculations, the testing device and final product. The electromagnetic FEA model of the capacitor-driven inductance coil gun was constructed...
