ince the early 1990s, hedge funds have become an increasingly popular asset class. The amount invested globally in hedge funds rose from approximately $50 billion in 1990 to approximately $1 trillion by the end of 2004. 1 And because these funds characteristically use substantial leverage, they play a far more important role in the global securities markets(More)
This paper proposes a technique for suppressing low-frequency band noise from speech signal. In practice, speech is often corrupted by color noise like car and multi-talker babble noise that affect mostly the low-frequency region of speech signal. We propose a straightforward approach for noise reduction by utilizing bone conducted (BC) speech. Lower(More)
Police work is one of the most stressful occupations in the world due to their enormous stresses, uncertainty in work, lack of support from the superior, etc. They were suffering from different types of physical and mental disorders. But only a few studies were carried out in India. The present study was conducted to evaluate the cardiovascular status of(More)
The paper surveys the principal generative syntactic assumptions that have been proposed for ergative construction and discusses the pattern of the ergative case marking in Assamese. For a language L which shows some mixed properties of ergativity and accusativity in a certain respect R, the language L is said to be split-ergative with respect to R(More)
This article is a limited assessment of the agricultural production economics literature since 1982 that resulted from dual modeling approaches. Contributions have removed several perceived obstacles to dual modeling, such as testing curvature, identifying the technology when prices are collinear, and examining dynamics of production. Some contributions(More)
In this paper we propose a digital logic inverter based on Graphene Nanoribbon Field Effect Transistor (GNR-FET) using ratioed circuit topology. Different types of GNR-FET architectures have been analysed through their current-voltage characteristics to find their probable applications like interconnect, on-chip resistance etc. Here electronic transport(More)
The novel electronic properties of graphene nanoribbons (GNRs) including purely two-dimensional structure along with its tunable bandgap have led to intense research into possible applications of this material in nanoscale devices. However, as yet, dimensions of its possibilities in practical device levels have remained inconsistent. In this paper we(More)
