In this paper, we address the problem of identifying periodically occurring patterns in a time series. The domain of data-center management is the primary focus. Data here comprises of request latencies, resource utilization of servers, data center workload etc. to name a few. Although periodicity detection has been researched, the past work does not(More)
This paper presents a simple, yet novel, approach to address the problem of spike detection. The definition of a spike varies with the domain under study. This results in domain-specific solutions that are often rendered unusable in other domains. Moreover, the spike detection algorithms proposed in the past are effective only when suitably tuned.

There seems to be ample evidence supporting the view that glutamate plays a significant role in the mammalian brain as a neurotransmitter. It is considered to be a likely transmitter candidate in one or more hippocampal pathways. Recently it has been visualized in excitatory, possibly glutamatergic, neurons in the hippocampus. Glutamate has been proposed to(More)
