And the complexity challenge is particularly acute in the most crucial place -- security -- in a world where potentially hostile programs are continuously arriving across the Internet to run on potentially vulnerable computers.
In many new applications fields, such as surveillance, networks, and sensor technologies, the generating data are time-varying, unpredictable, uncertain, continuously arriving, and must be processed online.
The dynamic online job shop scheduling problem (JSSP) is formulated based on the classical combinatorial optimization problem – JSSP with the assumption that new jobs continuously arrive at the job shop in a stochastic manner with the existence of unpredictable disturbances during the scheduling process.
Such widely used data intensive applications don't directly target their data models for persistence storage, because the continuously arriving multiple, rapid, time-varying, and unbounded streams lose the support for storage as an entirety [31], and a portion of arrived stream is required to keep in the memory for initial processing.
The concepts of unbounded data streams and windows are visualised in Figure 2. The small circles represent tuples continuously arriving over time and constituting a data stream, whereas the thick rectangular frame illustrates the window operator applied to this unbounded sequence of tuples.
MUSTN1 (Fig. 2B, left), for example, is associated with cellular proliferation and differentiation in bone tissue [38], and might play similar roles in the development and/or growth of newly-born neurons that continuously arrive in HVC, even in adults.
In a natural scenario, new invaders may continuously arrive, environmental changes are erratic and local adaptation may provide an additional advantage [ 14].
It is more likely that a proportion of these have resulted from an ongoing process of melanoma cells shed from other metastases continuously arriving in the microcirculation of the brain slowing down, attaching to endothelium, and finally, successfully implanting.
We grew our own food and clothed ourselves humbly but we were in arrears for the material costs of our building program, which had gone on more or less continuously as new members arrived.
Now email arrives continuously, and most emails demand some sort of action: Click on this link to see a video of a baby panda, or answer this query from a co-worker, or make plans for lunch with a friend, or delete this email as spam.
