“…The lowest geometric mean diameters were measured for Çakıldak and Tombul samples (Table 7). These physical properties are important for hazelnut cracking and separation machines; they are used to adjust the dimensions between cylinders in breaker systems (Demir et al, 2018). Furthermore, these properties could prove convenient for hazelnut drying and processing (Milošević and Milošević, 2017).…”

“…In recent years, researchers have largely focused on physical properties of agricultural products to investigate the relationship between the physical and chemical parameters (Ercişli et al, 2011;Sayıncı et al, 2015a;2015b;Bahrami et al, 2017;Demir et al, 2018;2019). For agricultural products, appearance, shape, and size are important parameters for engineered systems.…”

“…Shape and dimensional characteristics are commonly used to assess quality properties and to correlate them with other chemical quality parameters (Sadrnia et al, 2007;Sun et al, 2012;Sayinci et al, 2012;Bayrakdar et al, 2015;Demir et al, 2018;Alibabic et al, 2018;Gunduz and Ozbay, 2018). Shape and size are the primary designators of the variety and the primary indicators of quantity and quality (Brewer et al, 2007;Fıratlıgil-Durmuş et al, 2010;Costa et al, 2011;Milošević and Milošević, 2017;Sorkheh et al, 2018).…”

Hazelnut is one of the most popular nuts consumed by people; it has different cultivars in Turkey. The aim of the current study was to characterize some physicomechanical characteristics, shape features, color, and biochemical properties of 6 standard and 3 local hazelnut cultivars grown in Turkey. The shape and size properties of the samples were determined using image processing techniques as an alternative to conventional measurement methods. Additionally, principal component analysis (PCA) was used to classify the hazelnut samples in terms of the biochemical parameters of the hazelnut cultivars. According to the findings, the highest crude oil (63.25%) and lowest protein contents (13.63%) were observed in the Kalınkara cultivar. Oleic and linoleic acids were the major fatty acids for all hazelnut samples. While local Devedişi and standard Çakıldak cultivars had the highest oleic acid levels, the highest linoleic acid level was observed for the Dağ fındığı cultivar. The cultivars of Foşa had the highest Zn and Mn, while the highest Cu was found in the Tombul cultivar. The greatest surface and projected areas were calculated for the Kara fındık and Dağ fındığı samples, while the greatest hardness value was measured for the Devedişi cultivar. PCA revealed some positive and negative correlations between the physicomechanical and biochemical parameters. The present analyses revealed significant correlations between hardness and internal shell b* values and between Cu content and internal L*. Such correlations should be taken into consideration in food processing applications and machine design for these hazelnut cultivars.

“…As elliptic Fourier descriptors (EFDs), originally proposed by Kuhl and Giardina [11], can delineate any type of shape with a closed two-dimensional (2D) contour. Over the past several years, researchers have applied elliptical Fourier descriptors to various fields, such as agriculture [12], the human body [13,14], and ecology [15], but it has rarely been used in archaeological research. This study, however, combines the results of quantitative analysis and elliptical Fourier descriptors to study pottery typology.…”

Pottery is an important material in archaeological studies, and the accurate classification of pottery shapes largely depends on the experience and knowledge of archaeologists. In this thesis, pottery taken from the Gansu-Zhanqi site is used for sampling. Three-dimensional (3D) models of the pottery were obtained using 3D scanning, and a computer-assisted pottery typology was studied through quantitative analysis and elliptic Fourier descriptor. This method, which can enhance and supplement the traditional methods of classifying pottery in archaeology and thereby enrich the parameters and breadth of pottery analysis, represents a new means for exploring and experimenting with objective classification and provides a new tool for traditional archaeological analysis methods.
