DESIGN OF AN IMAGE PROCESSING SYSTEM FOR FABRIC DRAPE MEASUREMENT

KUMAŞ DÖKÜMLÜLÜK ÖLÇÜMÜ İÇIN GÖRÜNTÜ İŞLEME SISTEMI TASARIMI

The drape is mainly expressed as the bending behavior of the fabric under its own weight. The drape quality of the fabric varies according to the area of ​​use and the design criteria of the product to be produced. First of the drape coefficients of the samples was determined using developed image processing algorithm of the image frames taken with the newly designed machine vision system.

In the image processing technique, the quality and properties of the image frame have a significant effect on the targeted result. The mean of the bend length values ​​for weft/run and warp/weft directions and drape measurements were compared with the drape coefficient values ​​obtained from the developed machine vision system.

ELEKTRİKLİ BİR ARACIN BATARYA SİSTEMİNİN MODELLENMESİ MODELING THE BATTERY SYSTEM OF AN ELECTRIC VEHICLE

Lityum-iyon piller, yüksek güçleri, enerji yoğunlukları ve uzun ömürleri nedeniyle tipik olarak tercih edilen pil türüdür (Zhang ve diğerleri, 2018). Dirençler ve kapasitörlerden oluşan eşdeğer devre modelleri, bir pilin voltaj-akım davranışını simüle etmek için yaygın olarak kullanılmaktadır (Xia ve diğerleri, 2015). Bu çalışmada, lityum-iyon pillerin modellenmesi ve simüle edilmesi için Şekil 1'de verilen birinci dereceden bir RC eşdeğer devre modeli kullanılmıştır (Zhang vd., 2017).

Bu çalışmada kullanılan pil modelinin 20 ℃'deki parametre değerleri Tablo 1'de verilmiştir (Web1; Ehsani vd., 2010). Bir pilin şarj durumu, pile giren ve pilden çıkan elektrik akımı miktarı dikkate alınarak tahmin edilebilir (Ehsani ve diğerleri, 2010).

Yenilikçi kompozit malzemelerin geliştirilmesindeki ana odak noktalarından biri, takviyeler ile matris arasında uygun bir bağ sağlamaktır (Liotier ve diğerleri, 2019). Bu kabuk atıkları, mekanik performanslarını iyileştirmek ve malzemenin çevre dostu özelliklerini korumak için biyolojik olarak parçalanamayan polimerler için bir biyo-dolgu malzemesi olarak kullanılır (Mohamad ve diğerleri, 2014; Poompradub ve diğerleri, 2008). Kompozit malzemelere kil, talk ve kalsiyum karbonat gibi malzemelerin eklenmesiyle kırılma, nem içeriği ve eğilme elastisite modülü gerilme değerlerinde önemli olumlu gelişmeler sağlanmıştır (Glenn vd., 2001; Matsuda vd., 2013; Pushpadass ve diğerleri, 2008).

CEYHAN'DAKI BALLIKAYA HAVZASININ KARAKTERISTIK ÖZELLIKLERININ ARC-CBS ORTAMINDA BELIRLENMESI

Previously, the boundaries of the watershed were determined from the topographical paper maps (Ercan and Yuce, 2016). The main objective of this study is to derive the boundaries of the basin based on DEM via Arc-GIS environment for the study area located in Gaziantep, Turkey. Discharge point coordinates for the watershed obtained from the General Directorate of State Hydraulic Works in Turkey.

The basin drawing below (Figure 9a) is in raster format; however, this image must be converted from raster to vector (polygon) format to determine the area of ​​the basin and the length of the watercourse (Figure 9b). a) Ballikaya watershed (raster) b) Ballikaya watershed (polygon) Figure 9. Using freely available digital elevation models on the internet and Arc-GIS software, watershed boundaries can be accurately determined without relying on paper topographic maps.

GPU ACCELERATED INTUITIONISTIC FUZZY AND OTSU ALGORITHMS FOR FOREIGN LEAF DETECTION IN COTTON

PAMUKTAKİ YABANCI ELYAFLARIN GPU İLE HIZLANDIRILMIŞ SEZGİSEL BULANIK MANTIK VE OTSU ALGORİTMALARI İLE TESBİTİ

Thus, the threshold value of each frame obtained from the camera was automatically calculated and implemented on the image in time. In this study, the goal is to calculate the threshold value in each frame using the Otsu method instead of using a fixed threshold value. Literature research has shown that a fixed value is used as a threshold value in an intuitive fuzzy logic edge detection algorithm.

In this study, it is the first time that dynamic thresholding obtained by the Otsu method was used integrated with heuristic fuzzy logic. In this way, the threshold value for each image from the camera was calculated in real time and currently applied to the image.

The chemical properties (CP, CO, DM, ODM, ADF and NDF), biogas and methane production values ​​of the materials were discussed. The variance analysis of biogas, methane production and methane ratios of biogas is presented in Table 3. Biogas and methane values ​​in co-fermentation increased as the proportion of OW in the materials increased.

The average cumulative methane production of the materials from highest to lowest was determined to be 100%. The efficiency of biogas and methane production can be increased by co-fermentation of OW with CM.

ETKİSİ

In Laser Metal Deposition (LMD), powder material is supplied to the melting zone simultaneously with the movement of the laser. According to the result of the equation, the maximum energy intensity occurs in the central axis, that is, r = 0 point. One of the factors that gives the Gaussian distribution is the absorption effect of the material.

Part of the laser beam that affects the material is absorbed by the material and part of it is reflected. In equation (2), A is the absorption coefficient, PA is the amount of energy absorbed by the material, and P is the total energy of the laser.

HEAVY METAL POLLUTION INDEX (HPI) IN SURFACE WATER BETWEEN ALAKIRI DAM AND ALAKIR BRIDGE, ANTALIA-TURKEY. The Heavy Metal Pollution Index (HPI) indicates water quality and is calculated from the concentration of heavy metals in the water. The heavy metal pollution index (HPI) and the sub-index of each parameter (Qi) were calculated using the following correlations (Leventeli et al., 2019).

The water quality in K26 was identified as "very good"; the water quality in the remaining locations is marked as "good". Evaluation of the heavy metal pollution index for surface and spring water near a limestone mining area of ​​the lower Himalayas.
