IntroductionEnsuring quality of care in Low and Middle Income countries (LMICs) is challenging. Despite the implementation of various quality improvement (QI) initiatives in public and private sectors, the sustenance of improvements continues to be a major challenge. A team of healthcare professionals in India developed a digital community of practice (dCoP) focusing on QI which now has global footprints.MethodologyThe dCoP was conceptualised as a multitiered structure and is operational online atwww.nqocncop.orgfrom August 2020 onwards. The platform hosts various activities related to the quality of care, including the development of new products, and involves different cadres of healthcare professionals from primary to tertiary care settings. The platform uses tracking indicators, including the cost of sustaining the dCoP to monitor the performance of the dCoP.ResultSince its launch in 2020, dCoP has conducted over 130 activities using 13 tools with 25 940 registration and 13 681 participants. From April 2021, it has expanded to countries across the South-East Asia region and currently has participants from 53 countries across five continents. It has developed 20 products in four thematic areas for a targeted audience. dCoP is supporting mentoring of healthcare professionals from five countries in the South-East Asia region in their improvement journey. Acquiring new knowledge and improvement in their daily clinical practice has been reported by 93% and 80% of participants, respectively. The dCoP and its partners have facilitated the publication of nearly 40 articles in international journals.ConclusionThis dCoP platform has become a repository of knowledge for healthcare professionals in the South-East Asia region. The current paper summarises the journey of this innovative dCoP in an LMIC setting for a wider global audience.

Orthogonal frequency division multiplexing (OFDM) is recently introduced as a waveform candidate for6TH generation New Radio (5GNR) system and it is also popular for 5th generation wireless communication systems due to various advantages. Large peak to average power ratio is a major drawback of OFDM signal. It is necessary to reduce PAPR of OFDM system for power efficient operation of high power amplifier. This paper presents an improved Riemann sequence based SLM (IRSLM) for PAPR reduction of OFDM system. From the results, it is revealed that the PAPR of proposed scheme is improved by 1.9dB, 0.9dB and 0.4dB compared with CSLM, WSLM and Riemann based SLM (RSLM), respectively.

LED's are used for both lighting and data exchange in the rapidly expanding field of visible light communication. In this study, we have investigated the performance of indoor visible light communication with white LED using the modeling tool Opti system. Quality factor and log of BER measurements are used to assess the effectiveness of the Visible Light Communication system at various data rates and link lengths. This system, with a Q factor of 6.508, can deliver a 1 GB/s transmission rate across a connection distance of up to 3 m. The investigation is conducted for the NRZ-OOK modulation formats using a white LED as the communication source. When external ambient light influences are present, the performance of the VLC system is also examined, and its overall performance is improved by utilizing a rectangular optical filter.

The smart home is a setting where different electronic gadgets and machines are organized to give smart services to the homeowner on a far reaching premise. People. The elements gave by the applications to smart homes are being acknowledged and embraced by associations and individuals from one side of the planet to the other. this could be because of the different advantages that the arising internet of Things (IoT) advancements and gadgets, outfitted with sensors, cameras, or actuators, and ready to either accumulate data from the climate or perform legitimate errands, give as far as making clients' regular routines and occupations more straightforward. Ongoing checking, controller, security from interlopers, gas/alarm, and different capabilities are among the critical attributes of smart houses. Since delicate and individual information is overseen in smart homes, security and protection measures ought to be executed to shield clients' and organizations' information from encroachment while as yet guaranteeing the arrangement of trustworthy services. The review's decisions and suggestions assist us with understanding how clients' mentalities toward security are changing in smart homes as IoT home gadgets become more ordinary. Albeit a smart home arrangement in light of the Internet of Things can offer a superior and more compelling way to deal with healthcare the executives, end client reception is very low. The presentation of smart home healthcare services, which basically focus on the old, will be essentially hampered by these moderate clients. The discernment layer, transport layer, and application layer security defects might be available in most of recently evolved smart gadgets because of their designs, which are by and large very basic. Most of IoT security examination structures right now being used require extra elite execution equipment. Simultaneously, there hasn't been any attention on the new “mining” malware or other assault strategies that conspicuously take the gadget's figuring power. This paper plans and carries out a smart home security investigation framework as an answer for the previously mentioned issues.

In a mobile ad hoc network, packets are lost by interference occurrence in the communication path because there is no backup information for the previous routing process. The communication failure is not efficiently identified. Node protection rate is reduced by the interference that occurs during communication time. So, the proposed reliability antecedent packet forwarding (RAF) technique is applied to approve the reliable routing from the source node to the destination node. The flooding nodes are avoided by this method; the previous routing information is backed up; this backup information is retrieved if any interference occurred in the communication period. To monitor the packet flow rate of every node, the straddling path recovery algorithm is designed to provide an interference free-routing path. This path has more number of nodes to proceed with communication. These nodes have a higher resource level and also used to back up the forwarded data; since sometimes routing breakdowns occurred, data are lost, which is overcome by using a backup process. It improves the network lifetime and reduces the packet loss rate.

This paper addresses modeling and software simulation of parallel interconnection photovoltaic (PV) and solid oxide Fuel Cell (SOFC) to obtain continuous supply and hysteresis current controlled single phase inverter for hybrid generation system. Two arm Insulated Gate Bipolar Junction Transistor (IGBT) is applied to convert DC power produced by (PV-SOFC) into Alternating Current (AC) Supply. The proposed hysteresis controller is capable of reducing the total harmonic distortion, current regulation, and provides constant switching frequency. The DC-DC Boost Converter is implemented to track Maximum Power Point using Incremental Conductance (INC) Algorithm for efficient utilization of PV system. The synchronization between the inverter and the Grid is maintained by using Phase Locked Loop (PLL) within Hysteresis Band Controller. The performance of phase locked loop (PLL) based proposed hysteresis current controller of inverter is evaluated through MATLAB-Simulation. Simulation results are verified the effectiveness of suggested system.

Cellular systems are generally encountered with near-far problem. Several power control updating algorithms have been proposed to deal with this problem. One of the commonly used algorithms is proposed by Zander that drives all the mobiles to achieve the system threshold signal to interference ratio (SIR), that is necessary for a mobile to get the access of base station. This algorithm deals with the link gain matrix associated with the system. Removal policy is applied which removes a mobile from the network if it fails achieve threshold value after being given several trials. The system is rebalanced by changing the link gain matrix. This increases the capacity as new incoming users can be served by the system. In this paper, a new power updating algorithm for cellular system is proposed and simulated to show that mobiles converges faster in terms of number of iterations required to get system threshold.
