    Design of LED circuit card for an off-road lamp
    (2010) Yakışır, B.; Çil, Celal Zaim
    In this study a working lamp used on the working machines is designed by using the LED diodes instead of a halogen bulb. In the design, firstly a LED or a LED array and a proper driver circuit that can provide the required optical power are designed, and the working lamp developed are tested under various conditions. The luminous output values of the designed LED working lamp are compared with those of a commercial working lamp using a halogen bulb. It is evaluated that in automotive applications working lamps using LEDs could be successfully utilized depending on the optical efficacy of the LED used, the designs of the LED driver and the reflector.

"Diffraction of matter waves in time by an absorbing half-screen", 2010 National Conference on Electrical, Electronics and Computer Engineering, ELECO 2010, 2010 7th National Conference on Electrical, Electronics and Computer Engineering, ELECO 20102 December 2010 through 5 December 2010, pp. 429-432.
    Diffraction of matter waves in time by an absorbing half-screen
    (2010) Umul, Yusuf Ziya; 42699
    In this study, the scattering of matter waves that accompany to the quantum particles by an absorbing half-plane is examined. A quantum shutter, which is opened at an initial time, is proposed to close the semi-infinite complementary aperture of the half-screen. Hence the matter waves, confined in a determined region of space, transmits to the second region by scattering from the semi-infinite aperture. The mathematical expressions of the scattered fields are plotted numerically and interpreted according to the diffraction theory of Young.

    Citation Count: Preveze, Barbaros; Şafak, Aysel (2010). "Power consumption of novel throughput improvement methods", 2010 7th National Conference on Electrical, Electronics and Computer Engineering, ELECO 2010, 2 December 2010through 5 December 2010, pp. 676-679.
    Power consumption of novel throughput improvement methods
    (2010) Preveze, Barbaros; Şafak, Aysel; 17573
    The novel proposed method as a combination of Time Division Multiple Access (TDMA) and Orthogonal Frequency Division Multiple Access (OFDMA) called Orthogonal Frequency Division Most Congested Access First (OFDMCAF) provides spectrum sharing, buffer management and improves the throughput. In this work the power consumed by activating each cognitive method is analyzed in addition to the throughput improvement provided by each method used with OFDMCAF. It is shown at the end of the analysis that activation of each method also decreases the average power consumption even the same routing algorithm is used in all cases.
