BACKGROUND Selecting the most efficient vaccination schedule is an important issue. OBJECTIVE To assess the beneficial and harmful effects of accelerated hepatitis B vaccination schedules in high-risk healthy adults. METHODS We searched controlled trial registers of The Cochrane Library as well as MEDLINE, EMBASE, VIP Database for Chinese Technical Periodicals, and the Chinese National Know...

This paper considers the problem of scheduling hybrid flowshops with machine availability constraints (MAC) to minimize makespan. The paper deals with a specific case of MAC caused by preventive maintenance (PM) operations. Contrary to previous papers considering fixed or/and conservative policies, we explore a case in which PM activities might be postponed or expedited while necessary. Regardi...

For collective communications, the upper limit of a network's capacity is its liquid throughput. The liquid throughput corresponds to the flow of a liquid in an equivalent network of pipes. However, in communication networks, the aggregate throughput of a collective communication pattern (traffic) scheduled according to straight forward topology unaware techniques may be several times lower tha...

This paper presents a new energy-efficient MAC design to improve the performance of IEEE 802.15.4-based wireless sensor networks. Our proposed mechanism adaptively determines the sleeping schedules of sensor nodes based on the network traffic load to achieve the balance of throughput and energy consumption. This mechanism consists of two phases: schedule exchange phase and schedule generation p...

Creating quality construction schedules to mitigate delays often relies on experience. The lack of dissemination historic decision reasoning makes it harder. This study proposes a graph-based method find the time- and risk-efficient patterns from projects help schedulers improve productivity accuracy. leverages schedule data obtained Tier-1 contractor validates for excavation activities. result...
