Resource management is one of the most important engineering issues in 3G systems where multiple traffic classes are supported each being characterized by its required quality of service (QoS) parameters. Call admission control (CAC) is one of the resource management functions, which regulates network access to ensure QoS provisioning. Call Admission(More)
Lipid peroxidation in kidney of rats fed with vitamin B-6 deficient diet for a period of 12 weeks was studied with pair-fed controls. The basal lipid peroxide level as well as the degree of susceptibility to lipid peroxidation in presence of promotors such as NADPH, ascorbate, t-butyl hydroperoxide, Fe2+, Cu2+ and oxalate, were increased in vitamin B-6(More)
Lipid peroxidation in blood of vitamin B6 deficient rats was significantly increased when compared to pair-fed controls. The observed increased lipid peroxidation in vitamin B6 deficiency was correlated with high levels of lipids, metal ions and low levels of antioxidants, alpha-tocopherol, ascorbic acid and reduced GSH. Supplementation of methionine or(More)
Observed loss in body weight gain, increased lipid peroxidation reaction, decreased concentrations of antioxidants, ascorbic acid, alpha-tocopherol and reduced glutathione and antioxidant enzymes, glutathione peroxidase and catalase and increased concentration of hydroperoxides and hydroxyl radicals in vitamin B6 deficient rat liver [J Nutri Biochem, 2(More)
Lipidperoxidation in plasma of rats fed with vitamin B-6 deficient diet for a period of 12 weeks was studied with pair-fed controls. Plasma pyridoxal 5'-phosphate, alanine amino transferase and aspartate amino transferase, the markers of vitamin B-6 status, were significantly low in vitamin B-6 deficient rats. Plasma malondialdehyde level, conjugated dienes(More)
The shift factor of a permutation is the average of the displacement of elements. In this paper, we count the number of permutations having maximum shift factor in which adjacent elements not appearing together. 1. INTRODUCTION In a scrambling system, the signal is encrypted by rearranging the input (plain text) data using permutations. When the signal is(More)
The anticipation for the demand from low bandwidth to high bandwidth application leads to multiple-user class in mobile communication networks. In this paper, the connection admission control problem for multiple-user class with user mobility in mobile communication networks has been investigated. The user mobility and multimedia traffic are important(More)
People with limited mobility in the U.S. (defined as having difficulty or inability to walk a quarter of a mile without help and without the use of special equipment) face a growing informational gap: while pedestrian routing algorithms are getting faster and more informative, planning a route with a wheeled device in urban centers is very difficult due to(More)
