Background: Essential oils of medicinal plants such as chamomile are very complex natural mixtures which can contain compounds at quite different concentrations and some of their components have antioxidant and antimicrobial activities in foodstuff. Objective: The antioxidant and antimicrobial effects of chamomile essential oil in cake preparation were evaluated during 75 days of storag...

Dendritic side chains have been used to modify the binding environment in anthracene-based synthetic carbohydrate receptors. Control of length, charge, and branching enabled the positioning of side-chain carboxylate groups in such a way that they assisted in binding substrates rather than blocking the cavity. Conformational degeneracy in the dendrimers resulted in effective preorganization desp...

Objective: Tramadol is a synthetic analgesic with two mechanisms. The opioid and non-opioid mechanisms are responsible for tramadol side effects. Non-opioid side effects of tramadol are due to the reuptake inhibitions of serotonin and norepinephrine. Some of the side effects include anaphylactoid reactions, CNS depression, hypoglycemia, hypotension, respiratory depression, seizures, and seroton...

Masking is a common countermeasure against side-channel attacks. The principle is to randomly split every sensitive intermediate variable occurring in the computation into d+1 shares, where d is called the masking order and plays the role of a security parameter. The main issue while applying masking to protect a block cipher implementation is to design an efficient scheme for the s-box computa...

The discovery that natural and synthetic chemicals, in the form of excreted hormones and pharmaceuticals, as well as a vast array of compounds with domestic and industrial applications, can enter the environment via wastewater treatment plants and cause a wide variety of environmental and health problems even at very low concentrations, suggests the need for improvement of water recycling. Thre...

Accurate knowledge extracted from relevant datasets is essential for making reasonable and timely decisions using data mining algorithms. In order to both guarantee data quality collected and prevent disclosure of confidential or sensitive information, privacy preservation has become a major concern in the design of practical data mining applications. In this paper, a novel data distortion appr...

This paper describes a method of modeling singing styles by a statistical method. In this system, singing expression parameters consisting of melody and dynamics which are derived from F0 and power are modeled by context-dependent Hidden Markov Models (HMMs.) A modeling method of the parameters are optimized for dealing with them. Since parameters we focus on are essential but general ones for ...

We have applied two state-of-the-art speech synthesis techniques (unit selection and HMM-based synthesis) to the synthesis of emotional speech. A series of carefully designed perceptual tests to evaluate speech quality, emotion identification rates and emotional strength were used for the six emotions which we recorded – happiness, sadness, anger, surprise, fear, disgust. For the HMM-based meth...
