The invention discloses a work attendance recording method, a device, a server, an office system, and a storage medium. The work attendance recording method comprises following steps: working stationinformation of employees and pressure sensing information of corresponding seats are acquired; based on the pressure sensing information, accumulated lasting time of the employees on the working stations in a preset time range is calculated; it is determined whether the accumulated lasting time is equal to or larger than a first preset time threshold, and if the accumulated lasting time is equal to or larger than the first preset time threshold, it is determined that the employees are at normal working state. According to the work attendance recording method, the information of pressure generated by sitting of the employees on the working stations is adopted to determine employee working duration, the employee working duration is adopted to determine whether the employees are at normal working states, so that real-time statistic and reflection of employee working states is realized, the defects of punching time card record are avoided, work attendance record cheating is avoided effectively, and work attendance record accuracy is increased.

The base motivation of Mobile Cloud Computing was empowering mobile devices by application offloading onto powerful cloud resources. However, this goal can’t entirely be reached because of the high offloading cost imposed by the long physical distance between the mobile device and the cloud. To address this issue, we propose an application offloading onto a nearby mobile cloud composed of the mobile devices in the vicinity - a Spontaneous Proximity Cloud. We introduce our proposed dynamic, ant-inspired, bi-objective offloading middleware - ACOMMA, and explain its extension to perform a close mobile application offloading. With the learning-based offloading decision-making process of ACOMMA, combined to the collaborative resource sharing, the mobile devices can cooperate for decision cache sharing. We evaluate the performance of ACOMMA in collaborative mode with real benchmarks - Face Recognition and Monte-Carlo algorithms - and achieve 50% execution time gain.
