Compressing a task means that its period is prolonged while its computation time keeps unchanged. An interesting problem is to find the earliest time to release new tasks without any deadline missing,that is,the earliest smooth insertion time. In this paper,a general frame to calculate the earliest time with multiple rounds of deadline checking is given,which shows that the checking can be done from the request time of the new tasks. A smart way is provided and proved,which takes the value of theΔchecking of the current round as the time step to the next. These techniques potentially reduce the amount of the calculation and the number of the rounds of the checking to get the earliest time.

(NPC) were held in Beijing. At the sessions, attendees discussed western development in China, stateowned enterprise reform, China’s WTO accession, giving aid to poorer regions, new legislature and the Taiwan Question. Because the year 2000 is the last year for Chinese state-owned enterprise reform and the 87 poverty allevia- tion projects. much planning was done at the sessions, making this year sessins particularly significant.展开更多

The event-related potential evoked by the old-new memory recognition task in the oddball paradigm is suitable for examining the neural processes involved in malingered neurocognitive deficits. Forty-four undergraduates were randomly assigned to a simulated malingering group and a truth-telling group, Another 22 patients with head injudes were enrolled as a control group. All participants completed the old-new memory recognition task in the oddball paradigm. The mean P300 amplitude of the simulated malingering group was significantly reduced compared with the truth-telling group （P 〈 0.01）, but was increased compared with the control group （P〈 0.01）. These results revealed that the P300, evoked by the old-new memory recognition task of the oddball paradigm, may be a helpful indicator for determining cognitive malingering.展开更多
