Construction machine ingress and maintenance is burdensome. Evaluating the operator's physical load is thus important according to individual differences of the operators and machines. This paper presents a feasibility study for the physical load evaluation of two real-life operators of two excavator machines by motion measurement experiment in actual construction fields. Wearable inertial measurement units are used to capture the full-body posture of the operator. Insole foot pressure sensors and a strain gauge on the machine are used for measuring the contact forces. Physical load indices such as joint torques, the Ovako working posture analyzing system (OWAS), and the base-of-support (BoS) are calculated by kinematic and dynamic analysis of the digital human (DH). Applicability and effectiveness of evaluating physical load based on measurement in actual construction fields were discussed. Our results indicated that the joint torque evaluation is applicable to almost cases, however, the BoS and the OWAS are effective for a part of works.

Dual-functional Radar and Communication (DFRC) has become one of the key technologies of advanced wireless systems. This is because of the continuous development of mobile communication, the scarcity of spectrum and the potential network applications. In this paper, we propose a symbol-level precoding optimization scheme for Multi-Input-Multi-Output (MIMO) radar and multi-user Multiple-Input-Single-Output (MU-MISO) communication systems. More specifically, the weight sum of communication rate and radar detection probability are maximized by jointly optimizing the precoding vector and bandwidth allocation. Meanwhile, it includes the condition of ensuring the receiving signal-to-interference-plusnoise ratio (SINR) at receivers, the interference to the radar and the transmission power budget at the base station (BS). Compared with the traditional beamforming based on Semidefinite Relaxation (SDR), the feasible area of the optimization problem is extended. Based on the concept of constructive interference, the harmful multi-user interference (MUI) is converted into a beneficial signal. So the communication rate is ensured and the system performance is improved. Numerical simulations show that our proposed method achieves a better result of the object function compared to benchmark methods, while obtaining a favorable bandwidth allocation.
