Long‐Tea‐CLIP: An Expert‐Level Multimodal AI Framework for Fine‐Grained Green Tea Grading Across Five Sensory Dimensions

open access: yesAdvanced Science, EarlyView.
Long‐Tea‐CLIP (Contrastive Language‐Image Pre‐training) presents a multimodal AI framework that integrates visual, metabolomic, and sensory knowledge to grade green tea across appearance, soup color, aroma, taste, and infused leaf. By combining expert‐guided modeling with CLIP‐supervised learning, the system delivers fine‐grained quality evaluation and

K2 Stream Cipher

2008
A variety of different clock-controlled stream ciphers and attacks on them have been described in a number of papers. However, few word-oriented algorithms with an irregular clocking mechanism have been proposed. This paper proposes a new design of irregular clocking for word-oriented stream ciphers that is dynamic feedback control and show analysis ...

Historical Stream Ciphers

2015
It is desirable that both the encryption and decryption functions be public knowledge and so the secrecy of the message, given the ciphertext, depends totally on the secrecy of the secret key k. Although this well-established principle, called Kerckhoffs’ principle, has been known since the mid-1800s some companies still ignore it and choose to deploy ...

Modern Stream Ciphers

2015
We can interpret a pseudo-random function as a stream cipher. Let {F k } K be a PRF family with codomain C of bitstrings of length l. The PRF family immediately defines a stream cipher for messages of length l bits.
