Message Service System Evolution and General Frameworks

With the development of message service in telecom networks as well as the Internet,multiple message service formats have been emerging,including Short Message Service (SMS),Multimedia Messaging Service (MMS),Mobile Email Message (MEM) and Instant Message (IM).Based on the latest research achievements of OMA CPM Organization and GSMA RCS Organization,the message service evolution may have two phases:Integration and convergence,with corresponding overall framework realization methods.

Fever Outpatient Service of General Hospital Applies “1 + 3 + 3” Emergency Management Mode to Deal with COVID-19 Pandemic

Purpose: To discuss the effect of “1 + 3 + 3” emergency management mode to deal with COVID-19 pandemic in fever outpatient service of general hospitals. Method: This paper analyzes and summarizes the problems encountered by fever outpatient service in dealing with the COVID-19 pandemic from three aspects of “One Team”, “Three-Key” Control and “Three Mosts”. Results: The application of “1 + 3 + 3” emergency management mode can effectively boost the orderliness and efficiency of fever outpatient service in dealing with COVID-19 pandemic. Conclusion: The “1 + 3 + 3” emergency management mode provides a new management mode and idea for dealing with COVID-19 pandemic, so the fever outpatient service of general hospitals can better improve the national overall anti-pandemic situation.

Remote positioning system based on GPS/GPRS

Considering the need of target positioning,a remote positioning system is designed based on global positioning system(GPS)and general packet radio service(GPRS);The data collection terminal is based on microcontroller unit(MCU)PIC24FV301.It uses GPRS network to create wireless link and transmits GPS source information which is collected by LEA-5H board to monitor center on the Internet.The monitor center obtains the target information through processing and analysis of the calculated data.Actual operation results indicate that the designed system has excellent performance and achieves the goal of the remote location.

Co-Simulation of an SRG Wind Turbine Control and GPRS/EGPRS Wireless Standards in Smart Grids

Wind energy can be considered a push-driver factor in the integration of renewable energy sources within the concept of smart grids.For its full deployment,it requires a modern telecommunication infrastructure for transmitting control signals around the distributed generation,in which,the wireless communication standards stand out for employing modern digital modulation and coding schemes for error correction,in order to guarantee the power plant operability.In some developing countries,such as Brazil,the high penetration of commercial mobile wireless standards GPRS and EGPRS(based on GSM technology)have captivated the interests of the energy sector,and they now seek to perform remote monitoring and control operations.In this context,this article presents a comparative performance analysis of a wireless control system for a wind SRG,when a GPRS or EGPRS data service is employed.The system performance is analyzed by co-simulations,including the wind generator dynamics and the wireless channel effects.The satisfactory results endorse the viability and robustness of the proposed system.

Control of Progressive Collapse of the Structure Using Shear Wall

The vulnerability of reinforced concrete(RC)building systems to progres­sive collapse has turned out to be a challenging trouble for professional structural engineers so as to prevent total failure on account of nearby dam­age.The goal of this paper is to enhance the knowledge of such buildings’behavior underneath several scenarios of misplaced columns at different floor stages,and their capacity for progressive collapse.The homes had been analyzed following the guidelines for progressive collapse evalua­tion and design organized by means of the general services administration guidelines(GSA).The progressive collapse of a ten story structure sub­jected to a simplest gravity load is taken into consideration and the column has been eliminated at one place and the spread damage is evaluated.The progressive collapse study has been carried out by way of removing the column at a diagnosed crucial locations(at corner,middle and at interi­or)as in line with GSA guidelines.Static analysis is done using analysis program ETABS.For each case,the consequences were taken in terms of demand capacity ratio(DCR)at critical section,and as a result the structure has been assessed for it’s susceptible to progressive collapse.The availabil­ity of shear wall is made on the component wherein collapse occurred and DCR values are mentioned.After imparting the shear wall to the structure,the progressive collapse of the structure because of accidental load may be controlled in order that the GSA guidelines recommended DCR value would be within the range.

On international trade in educational services:an interpretation of the regulations and China’s WTO commitments

The General Agreement on Trade in Services(GATS)of the World Trade Organization(WTO)covers educational trade services.Hence,all the regulations of the GATS have to be followed in the international trade of educational services.Having acceded to the WTO,China is starting to fulfill the rights and obligations as a member by completely respecting international trade,services and intellectual property laws.At the same time,it is also starting to fulfill some of the commitments it made in the GATS,such as expanding activities on trade in educational services.Comprehending the fundamental regulations and China’s commitments is significant towards promoting China’s international trade in educational services.
