چکیده

Using five-year-monitoring observations, we carried out a blind search for pulses rotating radio transient (RRAT) J0139+33 and PSR B0320+39. At the interval ±1.5 m of time corresponding to source passing through meridian, detected 39377 individual pulsar B0320+39 1013 RRAT J0139+33. The share registered from total number observed periods is 74%, it 0.42%. signal-to-noise ratio (S/N) strongest is, approximately, following: S / N = 262 (for B0320+39) 154 J0139+33). We obtained distributions in S/N units transient. could be approximated with lognormal power dependences. For pulsar, dependence lognormal, turns into at high values S/N; J0139+33, distribution by energy described broken (bimodal) an exponent about 0.4 1.8 ( ≤ 19 ≥ 19). did not detect regular (pulsar) emission Analysis data suggests that giant pulses.

Femtosecond damage threshold at kHz and MHz pulse repetition rates

Femtosecond laser-induced damage threshold (LIDT) measurements for different optical components are well studied for a set of laser pulse repetition rates spanning the range between 1 Hz and 1 kHz. Recent years saw the advent of high-repetition-rate femtosecond systems with relatively high pulse energy. Therefore investigation of LIDT in the MHz region is essential. We performed several compara...

High Speed RFID/NFC at the Frequency of 13.56 MHz

Data-intensive applications based on NFC (Near Field Communication) or applications for healthcare/e-government will need an increase of the actual defined and standardised transmission rates of 848 kbit/s. It is topic of this work to point out physical layer parameters, limitations and concepts, allowing to enhance the transmission rate of passive 13.56 MHz RFID Systems. Additionally ongoing s...

Preliminary Design of Spacecraft Attitude Control with Pulse-Width Pulse-Frequency Modulator for Rest-to-Rest Maneuvers

In this paper, the preferred region of design parameters for quasi-normalized equations of single-axis attitude control of rigid spacecraft using pulse-width pulse-frequency modulator (PWPFM) is presented for rest-to-rest maneuvers. Using the quasi-normalized equations for attitude control reduces the system parameters, that is, the moment of inertia, the filter gain, and the maximum torque of ...

Gbt Polarization Observations of 100 Pulsars at 774 Mhz

We report on polarimetric observations of 100 pulsars centered on 774 MHz, made using the Green Bank Telescope (GBT), presenting their polarization profiles and polarized flux densities and comparing them with previous observations when possible. For 67 pulsars, these are the first such measurements made. Polarization profiles of 8 millisecond pulsars in our sample show wide profiles and flat p...
