We introduce a robust and efficient mix-network for exponentiation, and use it to obtain a threshold decryption mix-network for ElGamal encrypted messages, in which mix servers do not need to trust each other for the correctness of the result. If a subset of mix servers cheat, they will be caught with an overwhelming probability, and the decryption can restart after replacing them, in a fashion...

We propose a variant mix-net method, which we call a “marked mix-net” . Marked mix-nets avoid the extra cost associated with verifiability (producing a proof of correct mixing operation), while offering additional assurances about the privacy of the messages, compared to a non-verifiable mix-net. With a marked mix-net, each mix-server adds an extra secret mark in each ciphertext, and the input ...

This study investigated the use of waste chicken feather (barbs and rachis) as reinforcement in cement-bonded composites. A series of composite boards consisting of various proportions of waste feather, cement, sand, and chemical admixtures were prepared. Mix workability decreased significantly as the proportion by weight of feathers or ground feathers increased from 5% to 20%. Boards containin...

In this position paper, I reflect upon the question “Should AI stay married to Ed?”, specifically referring to how research in AI and Education should cross-fertilize to define AIED as an independent practice, beyond its composite fields. In my view, a mix of approaches, inspired by cognitive science, should serve to formulate characteristic research questions for the AIED community. Such quest...

applying robust optimization to solve product mix problem in automotive industries in this article, applying robust optimization in product mix problem in automotive industries is presented. the problem includes determining both the quantity and the identification of each product to produce to maximize profit. at first, the deterministic model will be presented. then, robust model of product mi...

Many health care providers and policy makers believe that health care financing systems fail to reward high-quality care. In recent years, federal and private payers have begun to promote pay for performance, or value-based purchasing, initiatives to raise the quality of care. This report describes conceptual issues in the design and implementation of pay for performance for chronic kidney dise...

The study implements the consequential life cycle assessment (CLCA) to provide a market based perspective on how overall environmental impact will change when shifting glass fibres to flax fibres as reinforcements in composite fabrication. With certain assumptions, the marginal flax fibre supply is identified to be a combination of Chinese flax fibre (70%) and French flax fibre (30%). Due to in...
