Maximize the system capacity

In this paper, we investigate the physical layer secrecy performance of multiple-input multiple-output (MIMO) system with transmission antenna selection (TAS) and receiver maximal-ratio combining (MRC) in the presence of a single antenna passive eavesdropper over dissimilar fading channels.

The Digital Video Broadcasting Next Generation Handheld (DVB-NGH) standard has adopted many advanced technologies, including overhead reduction schemes, to maximize the system capacity. However, some of the overhead reduction schemes of Layer-l (LI) signaling result in increased initial capture time delays. In order to get a more flexible trade-off between overhead reduction and initial capture time delay, a full-truncated Ll signaling scheme is proposed in DVB-NGH systems. Simulation results demonstrate the effectiveness ofthe proposed scheme.

India's agricultural extension system is at a pivotal point in its development. During the past 50 years, the Indian extension system has evolved to reflect national priorities. At the outset, extension worked to bring about broad-based rural development. However, the food crises starting in the late 1950s refocused the efforts of extension on food security and increasing food production. The combination of Green Revolution technology in the late 1960s and Training and Visit (T&V) Extension in the mid-1970s enabled India to achieve food self-sufficiency during the 1980s–1990s.

Buchanania lanzan (Chironji) a member of family Anacardiaceae consist of a hard nut that on decortication yields kernel containing 52% of oil and this oil is used as a substitute for olive and almond oil. Also, kernel is used for sweet meals, medicinal purpose, cosmetics etc. By manual decortication the capacity was observed to be minimum and recovery of whole kernel was nearly 12% only. This manual method is time consuming, laborious, inefficient and there is fear of injury to fingers.

The present work was carried out to evaluate the removal of Coomassie brilliant blue dye by adsorption onto a magnetized activated carbon nanocomposite (MNSA) prepared from Nigella sativa L. (NS) waste. Different techniques, including infrared spectroscopy, scanning electron microscopy, and nitrogen adsorption/desorption, were used to characterize MNSA to investigate its adsorption properties. Adsorption experiments were carried out by simultaneously optimizing four variables that usually present a strong effect in adsorption studies.

Drugs Acting on the Sympathetic Nervous System of the sympathetic division can be considered a means by which the body achieves a state of maximal work capacity as required in fight or flight situations. In both cases, there is a need for vigorous activity of skeletal musculature. To ensure adequate supply of oxygen and nutrients, blood flow in skeletal muscle is increased; cardiac rate and contractility are enhanced, resulting in a larger blood volume being pumped into the circulation. Narrowing of splanchnic blood vessels diverts blood into vascular beds in muscle.

Network Access and Synchronization Overview As we have described in Chapters 3 and 6, the SS/CDMA uses orthogonal CDMA in both uplink and downlink. The orthogonal CDMA can reject the interference between the user traffic channels and thus maximize the system capacity. However, the use of orthogonal CDMA in the uplink requires a network-wide synchronization of all satellite receptions (global synchronization). The accuracy of the synchronization at steadystate and the speed at which synchronization is acquired depends on the propagation environment, i.e.
