This paper presents a local audio watermarking method based on the dual-tree complex wavelet transform (DT CWT) and distortion-compensated dither modulation (DC-DM).Specifically, we perform DT CWT on extracted audio segment, and embed the watermark signal in the decomposed low-pass coefficients.During the embedding process, the selected coefficient
Food Safety System Design Using Hazard Analysis Critical Control Point (HACCP) on Beverage Product X at a Milk Tea Producer
Food safety is a primary concern in food industry.Hazard Analysis Critical Control Point (HACCP) is a systematic preventive approach that aims to ensure food safety in a comprehensive manner, starting from raw material retrieval from supplier, production phase, up to the distribution to end consumers.Furthermore, the approach is capable of reducing
Stress distributions along the roll contact arc
The article provides the results of a mathematical description of Cloche the distribution of contact stresses of a roll module with smooth rollers.Analysis of the developed models shows that when the rollers rotate, the maximum of the normal stress distribution diagram is displaced in the direction opposite to the movement of the material being pro
