Mobile communication standards have been developed into a new era of B5G and 6G.In recent years,low earth orbit(LEO)satellites and space Internet have become hot topics.The integrated satellite and terrestrial systems have been widely discussed by industries and academics,and even are expected to be applied in those huge constellations in construction.This paper points out the trends of two stages towards system integration of the terrestrial mobile communication and the satellite communications:to be compatible with 5G,and to be integrated within 6G.Based on analysis of the challenges of both stages,key technologies are thereafter analyzed in detail,covering both air interface currently discussed in 3GPP for B5G and also novel network architecture and related transmission technologies toward future 6G.

The system integration of image processing

An integration system was designed to apply to the remote communication of optics and electronics detection systems, which was integrated with programmable DSP and FPGA chirps in addition to a few Application Specific Integrated Circuits （ASICs）. It could achieve image binarization, image enhancement, data encryption, image compression encoding, channel encoding, data interleaving, etc., and the algorithms of these functions might be renewed or updated easily. The CCD color camera being a signal source, experiments had been done on the platform with a DSP chirp and a FPGA one. The FPGA chirp mainly realized the reconstruction of image’s brightness signal and the production of various timing signals, and the DSP chirp mainly accomplished the other functions. The algorithms to compress image data were based on discrete cosine transformation （DCT） and discrete wavelet transformation （DWT）, respectively. The experiment results showed that the developed platform was characterized by flexibility, programmability and re- configurability. The integration system is well suitable for the remote communication of optics and electronics detection systems.

＜正＞There is no professional injection simulation software in metal powder injection industry,so we propose to establish shrinkage rate formula for different materials and sintering temperature.On the basis of large number of experiments and data analysis, we have been verified the correctness of the formula. We have finished the design of injection mold by UG MoldWizard modules,and realized simulation and analysis of injection process with MoldFlow software. Through the mould concurrent development process, it has completed the CAD/CAE integration of the mould,and achieved the optimal design of the mould, which wil greatly improve the development efficiency of the mould.

The widespread diffusion of renewable energy sources calls for the development of high-capacity energy storage systems as the A-CAES(Adiabatic Compressed Air Energy Storage)systems.In this framework,low temperature(100℃–200℃)A-CAES(LT-ACAES)systems can assume a key role,avoiding some critical issues connected to the operation of high temperature ones.In this paper,two different LT-ACAES configurations are proposed.The two configurations are characterized by the same turbomachines and compressed air storage section,while differ in the TES section and its integration with the turbomachinery.In particular,the first configuration includes two separated cycles:the working fluid(air)cycle and the heat transfer fluid(HTF)cycle.Several heat exchangers connect the two cycles allowing to recover thermal energy from the compressors and to heat the compressed air at the turbine inlet.Two different HTFs were considered:air(case A)and thermal oil(case B).The second configuration is composed of only one cycle,where the operating fluid and the HTF are the same(air)and the TES section is composed of three different packed-bed thermal storage tanks(case C).The tanks directly recover the heat from the compressors and heat the air at each turbine inlet,avoiding the use of heat exchangers.The LT-ACAES systems were modelled and simulated using the ASPEN-Plus and the MATLAB-Simulink environments.The main aim of this study was the detailed analysis of the reciprocal influence between the turbomachinery and the TES system;furthermore,the performance evaluation of each plant was carried out assuming both on-design and off-design operating conditions.Finally,the different configurations were compared through the main performance parameters,such as the round-trip efficiency.A total power output of around 10 MW was set,leading to a TES tank volume ranging between 500 and 700 m^(3).The second configuration with three TES systems appears to be the most promising in terms of round-trip efficiency since the energy produced during the discharging

Greenhouse horticulture is associated to a significant energy consumption in temperate countries,mainly for lighting and for heating.Interestingly,the potential for energy optimization and energy savings is high but requires detailed models capable of considering various system configurations and control systems.This paper provides an open-source modeling framework capable of simulating and optimizing the design and the control of both the greenhouse and the generation systems covering all energy needs.The proposed model is composed of sub-models from different scientific fields:a greenhouse climate model,a crop yield model,a large number of energy generation and storage units models and different rule-based control strategies.The association of such state-of-the-art models in a single framework provides a powerful tool for optimization purposes and allows the definition of completely customized systems by means of an object-oriented interface.In this work,various control strategies are defined and simulated,thus demonstrating the capabilities of the proposed model.Results indicate that,by performing minor changes to the control of the thermal screen,heating consumption can be reduced by 3%without any loss in crop yield.The control of heat-generation units also has a significant impact on the operational costs,which vary by up to 17%when self-consumption levels are accounted for in the control strategy.
