Moderate resolution data for 40 quasi-stellar objects (QSOs) at z ≈ 2 were combined with spectra of comparable resolution of 59 QSOs with redshifts greater than 1.7 found in the literature to form a large, homogeneous sample of moderate resolution (∼1Å) QSO spectra. These spectra were presented and the statistics of the Lyman α forest were discussed in(More)
—Video coding is controlled by coding algorithms and limited in a frame or group of frames within a sequence, without considering channel status condition. Besides the conventional coding algorithm, we need to develop methods to take care of resource allocation in cooperative wireless a sensor networks (CWSNs). The most challenging part of the CWSNs is the(More)
Multimedia transmission in wireless multimedia sensor networks is often energy constraints. In practice the bit rate resulting from all the multimedia digitization formats are substantially larger than the bit rates of transmission channels that are available with the networks associated with these applications. For the purpose of efficient of storage and(More)
To demonstrate the influence of sliding friction of motion on a curve, a circular path is considered for simplicity on which a person slides from the highest point to the lowest point. A slide which represents a quadrant of radius 5 m and a person of mass 60 kg are considered for comparison in this paper. A Differential equation for motion considering the(More)
An extensive comparison of aerosol extinction has been performed using lidar and Stratospheric Aerosol and Gas Experiment (SAGE) II data over Gadanki (13.5 • N, 79.2 • E), a tropical station in India, following coincident criteria during volcanically quiescent conditions from 1998 to 2005. The aerosol extinctions derived from lidar are higher than SAGE II(More)
Scheduler is part of executing throughput in MAC Layer. A good scheduler provides high Quality of Service (QoS) and work towards getting more and more throughput. There are varieties of Scheduler based on different factors such as fairness and maximum feedback etc. Priority Scheduler is based on the need of the service to be catered. We have designed a(More)
We investigated the role of femtosecond (fs) laser wavelength on laser ablation (LA) and its relation to laser generated aerosol counts and particle distribution, inductively coupled plasma-mass spectrometry (ICP-MS) signal intensity, detection limits, and elemental fractionation. Four different NIST standard reference materials (610, 613, 615, and 616)(More)
Scheduler is part of MAC Layer that executes fair throughput. A good scheduler provides high Quality of Service (QoS) and work towards getting better throughput. There are varieties of Schedulers based on different factors such as fairness, maximum feedback, etc. Priority Scheduler is based on the need of the service to be catered. We have designed a(More)
