This paper proposes a new smart antenna beamforming scheme based on electronically steerable parasitic array radiator (ESPAR). The proposed method is capable of providing better capacity compared to the conventional ESPAR. The termination of each antenna element in this structure comprises a PIN diode in addition to a varactor. Using PIN diode besides the varactor provides more degrees of freed...

The joint power control and base station assignment for downlink is considered in this paper. We present an algorithm that finds a feasible joint base assignment and power control in the downlink which uses the base assignment that is computed by the joint algorithm in the uplink. We show that under some conditions the algorithm. also minimizes the sum of downlink powers. Interestingly, there i...

We propose a new design of the high channel capacity in Mobile Ad Hoc Network that uses the dense wavelength division multiplexing wavelength enhancement, in which the increasing in channel capacity and signal security can be provided. The increasing in number of channel can be obtained by the increasing in wavelength density, while the security is introduced by the specific wavelength filter, ...

Wireless mesh networks (WMNs) have gained considerable interest in expanding IEEE 802.11 networks to large-scale enterprise and community scenarios, primarily because its capability of providing wide-band ubiquitous network access to a significant number of users. However, the mesh nodes are typically limited in resources such as bandwidth, computation power and memory. Moreover, the shared wir...

This paper shows how the application of MIMO (multiple-input multiple-output) communication methods can enhance telemetry systems. The main contribution of MIMO to the communication system is improving spectral efficiency by exploiting spatial diversity of multiple antennas. For communications using high order QAM modulated signals, a blind MIMO equalizer is proposed in earlier works. In this w...

Current suggestions for capacities that should be targeted for moral enhancement has centered on traits like empathy, fairness or aggression. The literature, however, lacks a proper model for understanding the interplay and complexity of moral capacities, which limits the practicability of proposed interventions. In this paper, I integrate some existing knowledge on the nature of human moral be...

Page | 60 Capacity Enhancement of Reversible Data Hiding Technique Using Adaptive Embedding Cheenu Bansal, Preeti Gupta ABSTRACT: Reversible data hiding is current research area in field of data hiding. Reversible data hiding is defined as the process of hiding secret data in such a way that at receiver side both secret message and cover image can be recovered. This kind of reversibility is req...

Molten salts are used as heat transfer fluids and for short-term heat energy storage in solar power plants. Experiments show that the specific heat capacity of the base salt may be significantly enhanced by adding small amounts of certain nanoparticles. This effect, which is technically interesting and economically important, is not yet understood. This paper presents a critical discussion of t...
