Abstract: A system that facilitates obtaining a coarse estimation of a boundary of symbol with respect to time comprises a peak detector that detects a peak energy of an energy distribution output by a correlator, and an estimating component that adaptively estimates a boundary of the symbol based as a function of the detected peak energy. A parameter defined as a function of the magnitude to create a threshold value, the estimate obtained as a function of a comparison of the threshold with the energy distribution.

Abstract: A method of reducing power consumption of a server cluster of host systems with virtual machines executing on the host systems is disclosed. The method includes recommending host system power-on when there is a host system whose utilization is above a target utilization, and recommending host system power-off when there is a host system whose utilization is below the target utilization. Recommending host system power-on includes calculating impact of powering on a standby host system with respect to reducing the number of highly-utilized host systems in the server cluster. The impact of powering on is calculated by simulating moving some virtual machines from highly utilized host systems to the standby host system being recommended to be powered on. Recommending host system power-off includes calculating impact of powering off a host system with respect to decreasing the number of less-utilized host systems in the server cluster. The impact of powering off is calculated by simulating moving all virtual machines from the host system, which is being recommended to be powered-off, to less-utilized host systems.

Abstract: A process of producing solution heat treated aluminum alloy sheet material comprises subjecting hot- or cold-rolled aluminum alloy sheet to solution heat treatment followed by quenching and, before substantial age hardening has taken place, subjecting the alloy sheet material to one or more subsequent heat treatments involving heating the material to a peak temperature in the range of 100.degree. to 300.degree. C. (preferably 130.degree.-270.degree. C.), holding the material at the peak temperature for a period of time less than about 1 minute, and cooling the alloy from the peak temperature to a temperature of 85.degree. C. or less. The sheet material treated in this way can be used for automotive panels and has good a good "paint bake response", i.e. an increase in yield strength from the T4 temper to the T8X temper upon painting and baking of the panels.

Abstract: The present disclosure envisages an air purification system. The system comprises includes a shell, a blower, an electrode and a plurality of spikes. The shell has electrically-grounded wall(s), an inlet, and an outlet. The blower generates flow of air through the shell. The electrode is fitted within the shell between the inlet and the outlet and is electrically isolated from the shell body. The spikes extend from the electrode. The spikes have tips spaced apart from the inner surfaces of the walls and generate a corona between the tips and the inner surface of the walls when an high voltage electric current is passed through the electrode and thereby ionize gases and charge particles present in the air resulting in the particles being deposited on the inner surface of the walls of the shell.

Abstract: Techniques for performing frequency control using dual-loop automatic frequency control (AFC) are described. The dual-loop AFC includes an inner loop that corrects short-term frequency variations (e.g., due to Doppler effect) and an outer loop that corrects long-term frequency variations (e.g., due to component tolerances and temperature variations). In one design, a first inner loop is implemented for frequency control of a first system (e.g., a broadcast system), a second inner loop is implemented for frequency control of a second system (e.g., a cellular system), and at least one outer loop is implemented for adjusting a reference frequency used to receive signals from the first and second systems. Each inner loop estimates and corrects the frequency error in an input signal for the associated system and may be enabled when receiving the input signal from the system. The reference frequency may be used for frequency downconversion, sampling and/or other purposes.

Abstract: A timing estimation system and methodology are provided. In particular, a first pilot is employed in conjunction with three acquisition stages. In the first stage, an attempt is made to observe the leading edge the correlation curve associated with the first pilot symbol. In the second stage, a determination is made to confirm a leading edge was detected in the first stage by attempting to observe a trailing edge the correlation curve. Furthermore, during this second stage, a frequency loop is updated to account for frequency offset. The third stage is for observing the trailing edge the curve if it was not already observed in stage two. Upon detection receipt the first pilot, a second pilot can subsequently be employed to acquire fine symbol timing.
