Detection of hidden patterns in time series data via multiple-time FOD method
Erkuş, Ekin Can; Purutçuoğlu Gazi, Vilda (2019-06-23)
The periodicity in time series data can be detected by several frequency domains’ methods, especially, by the Fourier transform (FT). FT is a non-parametric method to convert the time domain data into the frequency domain and it is used in many engineering and data science applications. Recently this method which has been used to detect outliers in time series observations where the data may also include some systematic patterns is called “outlier detection via Fourier transform” (FOD). From our previous ...
Detection of underdeveloped hazelnuts from fully developed nuts by impact acoustics
Onaran, I.; Pearson, T. C.; Yardimci, Y.; Cetin, A. E. (2006-11-01)
Shell-to-kernel weight ratio is a Vital measurement of quality in hazelnuts as it helps to identify nuts that have underdeveloped kernels. Nuts containing underdeveloped kernels may contain mycotoxin-producing molds, which are linked to cancer and are heavily regulated in interviational trade. A prototype system was set up to detect underdeveloped hazelnuts by dropping them onto a steel plate and recording the acoustic signal that was generated when a kernel hit the plate. A feature vector comprising line s...

Detection of gamma irradiated spices with OSL method and its reliability
Irradiation has been accepted as an effective food safety method for various foods over 50 years. Gamma rays from radioactive isotopes of Cobalt 60 or Cesium 137 are used for food irradiation applications. The main concern about food irradiation is the detection of these irradiated foods and also loss of detection of irradiation through the storage period. Photo Stimulated Luminescence (PSL) is one of the physical techniques that can be used for irradiation detection. The aim of this study is to analyze the...
