A hybrid monitoring-sleeping method of wireless sensor and the wireless sensor are provided by the present invention, during N (N=N1+N2) monitoring-sleeping period, the wireless sensor monitors with the first monitoring duration, the wake-up data packet transmitted by the data acquisitor or the mobile terminal in the N1 monitoring-sleeping periods, and the wireless sensor monitors with the second monitoring duration, the wake-up data packet transmitted by the mobile terminal in the remaining N2 monitoring-sleeping periods. The first monitoring duration is longer than the second monitoring duration, N1 is less than or equal to N2, and the N1 first monitoring duration and the N2 second monitoring duration are alternatively distributed. Compared with the single monitoring duration used in the prior art, the total monitoring duration of the N monitoring-sleeping periods is reduced, as a result, the monitoring power consumption of the wireless sensor is also reduced.

In a ringtone control method executed in an electronic device receiving a call, an image capturing device captures images of surroundings of the electronic device in the event of receiving a call. The absence or presence of a person in the surroundings of the electronic device is detected and, if a person is found, whether the person is moving towards or away from the electronic device is detected according to the images. If the person is moving towards the electronic device, a ringtone volume of the call is decreased. If the person is moving away from the electronic device, the ringtone volume of the call is increased.

In this paper, a new scheduling problem is investigated in order to optimise a more generalised Job Shop Scheduling system with a Combination of four Buffering constraints (i.e. no-wait, no-buffer, limited-buffer and infinite-buffer) called CBJSS. In practice, the CBJSS is significant in modelling and analysing many real-world scheduling systems in chemical, food, manufacturing, railway, health care and aviation industries. Critical problem properties are thoroughly analysed in terms of the Gantt charts. Based on these properties, an applicable mixed integer programming model is formulated and an efficient heuristic algorithm is developed. Computational experiments show that the proposed heuristic algorithm is satisfactory for solving the CBJSS in real time.

Southeast China, characterized by a humid subtropical climate, is dominated by dense evergreen broad-leaved forests with the exception for the Changting area, which is one of the most eroded areas in southern China. Various methods have been employed to investigate regional soil erosion dynamics, yet these studies are limited to short periods and few sites. Dendrogeomorphological methods can alleviate this problem due to the long duration of tree rings and easy implementation for many sites. We present the first tree-ring-based soil erosion study in southeastern China, based on 123 exposed roots from 85 Pinus massoniana trees at six sites in Changting. The distinct reduction of cell lumen area of earlywood tracheids of exposed roots is a good bio-indicator for the first year of exposure due to soil erosion for this hot and humid area. The reconstructed soil erosion rates ranged from 4.26 to 43.50 mm/year with an average of 14.14 ± 8.05 mm/year. Soil erosion rate is the highest at the slopes of 10°–30°. This is in line with previous findings using other methods over the study area. In addition, soil erosion in this area is found to be closely related to vegetation types and summer precipitation.
