This paper presents a new technique for deterministic length reduction. This technique improves the running time of the algorithm presented in [?] for performing fast convolution in sparse data. While the regular fast convolution of vectors V1, V2 whose sizes are N1, N2 respectively, takes O(N1 logN2) using FFT, using the new technique for length reduction, the algorithm proposed in [?] perform...

This paper proposes an improved control method based on modified Delta-Sigma Modulator (DSM) to enhance transient response and improve harmonic contents of buck DC-DC converter. The main advantages of the proposed method are improving the output voltage frequency spectrum, correction of the output voltage harmonic contents and sideband harmonics, reduction of switching noise peaks at the output...

the power supply of remote sites and applications at minimal cost and with low emissions is an important issue when discussing future energy concepts. this paper presents modeling and optimization of a photovoltaic (pv)/wind/diesel system with batteries storage for electrification to an off-grid remote area located in rafsanjan, iran. for this location, different hybrid systems are studied and ...

the decline in avoidable mortality (am) and increase in life expectancy in shanghai is impressive. gusmano and colleagues suggested that shanghai’s improved health system has contributed significantly to this decline in am. however, when compared to other global cities, shanghai’s life expectancy at birth is improving as london and new york city, but has yet to surpass that of hong kong, tokyo,...

OBJECTIVE Non-supermarket food retailers can be a promising channel for increasing the availability of healthy foods in underserved communities. The present paper reports on retailer practices, attitudes and beliefs about the supply of healthy foods before and after the introduction of new subsidies for healthy foods by the US Special Supplemental Nutrition Program for Women, Infants, and Child...

In 1993, National Car Rental faced liquidation. General Motors Corporation (National's parent) took a $744 million charge against earnings related to its ownership of National Car Rental Systems. National faced liquidation, with the loss of 7,500 jobs, unless it could show a profit in the short term. National initiated a comprehensive revenue management program whose core is a suite of analytic...

Objective(s):Acrylamide (ACR) has many applications in different industries. ACR damages the central and the peripheral nervous system in human and animals. Importance of ACR-induced neurotoxicity encouraged researchers to find both different mechanisms involved in ACR neurotoxicity and potent neuroprotective agents. Therefore, this study was designed to investigate the protective effect of cro...
