The aim of this work is to answer the question how much quantum coherence a beam splitter able produce. To end we consider as variables under study both amount input states well characteristics. We conclude that there an optimal combination these factors making gain maximum. In addition, two mode squeezed vacuum arises studied state most capable gaining when passing through splitter. These resu...

noise is one of the most common workplace hazardous agents that can cause permanent hearing damage. workers in many industries are usually exposed to noise levels with high risks of hearing loss. accordingly this research aims to study the noise exposure and haring status of registered locksmiths who are exposed to harmful effects caused by several factors, such as key making machines loud nois...

BACKGROUND Hypoxia and nitric oxide (NO) play important roles in the onset and progression of glaucoma. Vascular endothelial growth factor (VEGF) is one of the main factors responsive to hypoxia and NO. In this study, we investigated the association between the BstUI C/T VEGF gene polymorphism and primary open angle glaucoma (POAG). METHODS 60 POAG patients and 78 healthy volunteers were enro...

Preferences are usually considered as binary relations applied on a set of objects, let’s say A. Preference modelling is concerned by two basic problems (see [31]). The first can be summarised as follows. Consider a decision maker replying to a set of preference queries concerning a the elements of the set A: “do you prefer a to b?”, “do you prefer b to c?” etc.. Given such replies the problem ...

We present the necessary and sufficient conditions on ordinal preferential information provided by the decision maker for the existence of a 2-additive capacity such that the Choquet integral w.r.t. this capacity represents the preference of the decision maker. These conditions help the decision-maker to understand the main reasons of the recommendations made when inconsistencies occur in his p...

Market Maker is a tool for creating agent based electronic marketplaces. Market maker supports automated product identification, buyer and seller qualification, and negotiations by software agents to facilitate transactions. The concept of agent based marketplace was first demonstrated through Kasbah, an electronic marketplace developed in the Media Lab's Software Agents group in 1996. Market M...

In this paper, we propose many-to-many voice conversion (VC) techniques to convert an arbitrary source speaker’s voice into an arbitrary target speaker’s voice. We have proposed one-tomany eigenvoice conversion (EVC) and many-to-one EVC. In the EVC, an eigenvoice Gaussian mixture model (EV-GMM) is trained in advance using multiple parallel data sets of a reference speaker and many pre-stored sp...
