    Carpet evaluation by imaging
    (Uludağ Üniversitesi, 2006) Gemci, Remzi; Ulcay, Yusuf; Altun, Şule; Mühendislik Mimarlık Fakültesi; Tekstil Mühendisliği Bölümü
    Carpets suffer an appearance loss with use. Carpet manufacturing companies, before marketing their product, are interested in determining the life of a carpet and the appearance change the carpet undergoes at different wear levels in order to test it acceptability in the market. Traditionally, carpet samples have been tested mechanically and their evaluation process, obviously involves a lot of subjectivity, is time consuming and is often unreliable. This study reviews the image techniques which eliminates instrumental testing in carpet evaluation.

    Cramér-Rao bounds for a sıngle real sinusoid: The known frequency case
    (Uludağ Üniversitesi, 2006) Dilaveroğlu, Erdoğan; Mühendislik Mimarlık Fakültesi; Elektronik Mühendisliği Bölümü
    The Cramér-Rao bounds for estimating the amplitude and phase of a real sinusoid of known frequency in white Gaussian noise are examined as the phase is varied, and the largest and smallest bounds and the corresponding critical phases are obtained.
