Effect of random perturbations on adaptive observation techniques
(© 2012 John Wiley & Sons, Ltd., 2012-05-10)
An observation sensitivity (OS) method to identify targeted observations is implemented in the context of four-dimensional variational (4D-Var) data assimilation. This methodology is compared with the well-established ...
New traveling wave solutions by the extended generalized Riccati equation mapping method of the (2 + 1) -dimensional evolution equation
(© 2012 Journal of Applied Mathematics, 2012)
The generalized Riccati equation mapping is extended with the basic (G ′ / G) -expansion method which is powerful and straightforward mathematical tool for solving nonlinear partial differential equations. In this paper, ...
Night mode face recognition using adaptively weighted sub-pattern PCA
(© 2012 IEEE, 2012)
The face recognition problem is made difficult by the great variability in head rotation and tilt, lighting intensity and angle, facial expression, aging, partial occlusion (e.g. Wearing Hats, scarves, glasses etc.), etc. ...
Tuning the TCP congestion control parameters to optimize client-server systems
(© 2012 International Journal of Multimedia and Ubiquitous Engineering, 2012)
The demand of high volume data communication over the internet is mounting day by day. In general, the performance of a communication system depends on the loss of data packets. It happens as there are multiple paths exist ...

Airtel Bangladesh Ltd. is a GSM-based cellular operator in Bangladesh. Airtel is the sixth mobile phone carrier to enter the Bangladesh market, and originally launched commercial operations under the brand name "Warid ...
Financial aid for the rehabilitation of individuals with spinal cord injuries in Bangladesh
(© 2012 Asia Pacific Disability Rehabilitation Journal, 2012)
In Bangladesh, a majority of individuals with spinal cord injuries (SCI) are either poor or very poor. In most cases, their families undergo extreme hardship as they lose the income of the only or main earning member, and ...
The modified benjamin-bona-mahony equation via the extended generalized riccati equation mapping method
(© 2012 Applied Mathematical Science, 2012)
The generalized Riccati equation mapping is extended together with the (G'/G) -expansion method and is a powerful mathematical tool for solving nonlinear partial differential equations. In this article, we construct twenty ...
Informal markets in sexual and reproductive health services and commodities in rural and urban Bangladesh

Beliefs and practices during pregnancy and childbirth in urban slums of Dhaka, Bangladesh
(© 2012 Choudhury et al.; licensee BioMed Central Ltd., 2012)
Worldwide urbanization has become a crucial issue in recent years. Bangladesh, one of the poorest and most densely-populated countries in the world, has been facing rapid urbanization. In urban areas, maternal indicators ...
Some new traveling wave solutions of the nonlinear reaction diffusion equation by using the improved (G′/G)-expansion method
(© 2012 Mathematical Problems in Engineering, 2012)
We construct new exact traveling wave solutions involving free parameters of the nonlinear reaction diffusion equation by using the improved (G ′ /G)-expansion method. The second-order linear ordinary differential equation ...
