Carrier aggregation technique plays a significant role in LTE-A to meet the need of higher data rate, it applies a number of frequency bands to transmit signals and therefore there is a promising research arising that it is indispensable to study the characteristics of the signal at different frequencies at a receiver, in order to make the receiving equipment adjusted to the discrepancy of the receiving...
The requirement of QoE is gradually increasing currently. Simultaneously, as the intermedium between the users and network, devices support collecting several QoS parameters which could predict expected QoE for users. However, a large quantity of mobile devices will become the obstacle for the QoS collection due to the costs of collection traffic. To solve it, this paper proposes a framework for collecting...
The static analysis of an given truck crane was conducted using FEA software ANSYS with the expectation of lightweight. The 3D geometric model of the crane frame was modeled by Pro/Engineer software, transported to the ANSYS software and analysised. Results show that the frame weight was reduced by 4.4%percent.
Belt conveyor is one the most important equipments for bulk material transportation. Traditional static analysis methods can not meet the design requirements of the heavy-duty belt conveyor. In this study virtual prototyping (VP) technology is applied to virtual simulation of belt conveyor. The simplified prototype of belt conveyor is established by RecurDyn software. And the VP can simulate belt...
