Parkinson's disease (PD), is an age-related, progressive neurodegenerative disorder that affects movement and is characterized by the loss of dopaminergic neurons in the nigrostriatal region. Although the clinical and pathological features of PD are complex, recent studies have indicated that microglial NADPH oxidase play a key role in its pathology. A(More)
Due to high complexity of VLSI systems used in various applications power dissipation becomes a limiting factor in VLSI circuits and systems, which arises from its switching activity influenced by the supply voltage and effective capacitance. Charging and discharging of the node capacitances in CMOS circuits creates power dissipation called as dynamic power(More)
In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique. As with other spread spectrum technologies, the transmitted signal takes up more bandwidth than the information signal that modulates the carrier or broadcast frequency. DS-CDMA is advantageous for ad hoc networks because it eliminates the need for any frequency or(More)
OBJECTIVES Amyloid-beta (Aβ) peptide deposition into insoluble plaques is a pathological hallmark of Alzheimer's disease (AD), but soluble oligomeric Aβ is considered to be more potent and has been hypothesized to directly impair learning and memory. Also, evidences from some clinical studies indicated that Aβ oligomer formation is the major cause for early(More)
— An effort is made to minimize the arithmetic intricacy of signal by using the VHDL module on FPGA. A curve fitting algorithm is used for finding the fundamental frequency of a given signal. Modification of algorithm is reducing the arithmetic complex-city become extinct the cubic solution. This is mature a fast approach for the signal processing and(More)
In telecommunications, direct-sequence spread spectrum (DSSS) is a modulation technique like other spread spectrum technologies; transmitted signal takes up additional bandwidth than the data signal which modulates the carrier frequency. DS-CDMA is beneficial for Ad hoc network because it eliminates the requirement for any frequency or time-slot(More)
In many kinds of equipment, it is important to produce readily control accurate waveforms of various frequencies and profiles such as agile frequency sources with low phase noise and low spurious signal content for communications, and simply generated frequency for industrial and biomedical applications. A direct digital synthesizer (DDS) provides many(More)
