The primary research objective is to reduce the dangers of rogue drones in our lives and the consequences of extremist groups, drug dealers, and organised criminals using them. The growing number of incidents involving modified drones proves the weakness of existing technology in stopping and neutralising errant drones such as the hand-held gun jammer, trained eagle, R.F. jammer, and others. This technology is not very likely to able to knock out a rogue drone and is incapable of stopping programmable drones. This article aims to examine the directed energy of HPM (high power microwaves) in using the electromagnetic field strength energy to damage the drone’s structure or burn its PCB board electronics. It goes on to analyse electronic attack using microwave power with high frequency to immediately switch off drones. The effectiveness of high microwave power for disrupting drones at different distances and in different weather conditions is evaluated. A study of the conical horn antenna of the magnetron coupling system, which has an operating frequency of 2.45 GHz, is also included.

The study investigates the mean reversion in 1-minute EURUSD. Intraday patters in FX seem of particular interest as more and more trades in the FX market are automated high frequency trades (HFT). The study reveals that the mean reversion is present in the intraday EURUSD. ADF test rejects unit root. The average of the deviation of EURUSD from its (moving) mean is close to zero. Furthermore when short and long positions are simultaneously open, the average maximum return achieved through 24 hour period is similar, providing yet another evidence for mean reversion and lack of weak form of market efficiency.

The paper tackles the problem of the efficiency of the foreign exchange market by examining selected intraday trading strategies. The research was conducted based on high-frequency data, i.e. one minute EUR/USD bid and ask rates. The paper demonstrates that a trading strategy based on high volatility and a mean-reversion pattern can provide outstanding results. This, in turn, is evidence against market efficiency, at least in the intraday horizon.

Praca porusza problem efektywności rynku walutowego poprzez ukazanie wyników inwestycyjnych dobowej strategii inwestycji. Badanie zostało przeprowadzone na podstawie danych wysokiej częstotliwości, tj. jednominutowych danych kursu kupna i sprzedaży EUR/USD. W pracy wykazano, że strategia oparta na założeniu wysokiej zmienności i tendencji powrotu do średniej może zapewnić doskonałe wynki inwestycyjne. Jednocześnie stwierdzono, że z uwagi na powyższe wyniki rynek walutowy nie jest efektywny w krótkim, dobowym kontekście.
