The integration of social networking and Internet of Things (IoT) concepts has attracted a growing interest of researchers and has promised to support new and powerful applications. However, the time it takes from development to the market for SIoT solutions is longer, especially if proper simulations are made to troubleshoot challenges in a timely manner. We propose the use of a multi-thread simulation tool that combines the existing testbeds, such as Network Simulator (Version 2), Devices Profile for Web Services, Objective Modular Network Testbed in Cplus plus, OPTNET, Parallel and Distributed Simulation (PADS), and J-Simtorun simulations in multiple threads to improve performance and save on time when simulating complex SIoT devices that are able to communicate with humans as well as interact with other devices. Through this approach, developers will shorten time-to-market for SIoT solutions and thus afford these solutions to users and improve the quality of life.

Simulation tools are essential for validating any research idea before it is being implemented. This is very essential for all the researchers irrespective of the field of research. Simulators provide a way for analysing the design.There are many simulation tools available for the network researchers. Network Simulators are used to test the performance of existing or new algorithms and protocols.Some of the simulation tools in networking include OPNET (OPtimized Network Engineering Tool), NS-2 (Network Simulator version 2), OMNET++ (Objective Modular NETwork Testbed in C++), GloMoSim (Global Mobile Information System Simulator), QualNet, NetSim (Network Simulator), JiST/SWANS (Java in Simulation Time/ Scalable Wireless Network Simulator), J-Sim (Java-based simulation) and NS-3 (Network Simulator Version 3). Simulation tools may be open source or commercial. In this paper, both the open source and commercial simulators are discussed. This survey reveals that for simulating large networks, simulators like OPNET, GloMoSim, QualNet, NetSim, JiST/SWANs and NS-3 can be used. For small network simulation NS-2 and J-Sim can be preferred. Open source simulators are poor in documentation. Commercial simulators have good documentation. Based on the requirements of the research, a proper simulation tool can be selected.

This study provides a retrospective analysis of work to ensure high quality of medical care in an unfavorable epidemic situation. The consequence of COVID-19 was the implementation of a program to prevent the spread of infection, the re-profiling of medical institu-tions, and the introduction of restrictive and anti-epidemic measures. The experience of our work has shown the effectiveness of changing the order of med-ical care, the organization of the functioning of de-partments and patient routing. The study reflects the measures implemented in the hospital departments, the Department of clinical and laboratory diagnostics, radiation diagnostics and pathology Department. To ensure the safety of patients, it was decided to place patients on a single bed according to the type of infec-tious boxes. The safety of employees was ensured by the use of personal protective equipment, minimiza-tion of contact time with patients, and preventive weekly examination of staff for SARS-CoV-2 infection. The organized and well-coordinated work of the en-tire staff of the institution made it possible to prevent the spread of COVID-19 among employees, to detect cases of infection in a timely manner, and to carry out appropriate isolation and monitoring measures. At the time of completion of infectious diseases departments, the mortality rate among patients was less than 9%. Our experience in reorganizing a multi-specialty facil-ity can be used in the future when working with pa-tients who have undergone COVID-19, as well as in the context of a worsening epidemic situation.

The learning process in madrasas (Islamic-based elementary schools) is seen as being able to contribute to instilling values and norms in students following Islamic teachings. The issue of organizational culture and teacher performance also becomes a determining factor in creating a quality learning process. In this research, the aim is to determine: 1) the effect of organizational culture on the quality of the learn-ing process; 2) the effect of teacher performance on the quality of the learning process; and 3) the influ-ence of organizational culture on teacher performance. Respondents in this study were all class teachers from three madrasas as a sample representing all public madrasas in the city of Bandar Lampung, Indo-nesia. The results obtained indicate that the variables of organizational culture and the quality of the learning process have an influence, with R squared of 0.67 or 67%, which is classified as moderate. This shows that madrassas have implemented predetermined work culture values, namely: a) integrity, the harmony between correct thoughts, words, and deeds; b) professionalism, working in a disciplined, competent, and timely manner with the best results; c) innovation, perfecting existing and creating new and improved techniques and ideas; d) responsibility, working thoroughly and with thought for the con-sequences; and e) being exemplary, setting a good example for others.

This paper reports a new parallel and distributed simulation architecture for OMNeT++, an open-source discrete event simulation environment. The primary application area of OMNeT++ is the simulation of communication networks. Support for a conservative PDES protocol (the Null Message Algorithm) and the relatively novel Ideal Simulation Protocol has been implemented.Placeholder modules, a novel way of distributing the model over several logical processes (LPs) is presented. The OMNeT++ PDES implementation has a modular and extensible architecture, allowing new synchronization protocols and new communication mechanisms to be added easily, which makes it an attractive platform for PDES research, too. We intend touse this framework to harness the computational capacity of highperformance cluster computersfor modeling very large scale telecommunication networks to investigate protocol performance and rare event failure scenarios.

E-literacy and education are important components in improving the quality of human resources needed in an organization. The purpose of this study is to reveal the importance of e-literacy and public policy education. The State Civil Apparatus (ASN) requires e-literacy and education to improve performance results so that public services can be maximized. This becomes interesting research in the development of science-based on the real events that occur in Indonesia. Where so far, e-literacy and education is only intended for the public, especially millennial generation. The research method used is the study of literature where data is obtained through various secondary sources that are relevant to theoretically strengthen research results. The findings explain that e-literacy and education are effective and efficient strategies in overcoming budget constraints and low levels of ASN competence. With e-literacy and public policy education, it is hoped that the professionalism of the ASN bureaucracy will increase and the quality of public services will be better.

The demand for reliable regional estimates from sample surveys has been substantially grown over the last decades. Small area estimation provides statistical methods to produce reliable predictions when the sample sizes in regions are too small to apply direct estimators. Model- and design-based simulations are used to gain insights into the quality of the introduced methods. In this article we present a framework which may help to guarantee the reproducibility of simulation studies in articles and during research. The introduced R-package saeSim is adjusted to provide a simulation environment for the special case of small area estimation. The package may allow the prospective researcher during the research process to produce simulation studies with a minimal eort of coding.

The existing technologies of production of compressor blade butts related with traditional machining methods, including broaching and milling. Application of these machining methods requires further superfinishing operations to ensure the required quality of compressor blades. The automated highly-productive grinding of blade butts is an effective method to improve performance and quality of blade production. The technologies of profile and contour grinding of blades of a rotor and a compressor stator provide an automated machining of the outer parts contour in the same coordinate system, implement machining based on 3-D models of theoretical blade surfaces, ensure the required quality parameters of the part surface layer without additional finishing operations.


With traffic increase in a wireless network beyond its capacity and as the number of connected devices continue to grow, the quality of service (QoS) degrades. In this paper we study the impact of mobility on throughput in the case of an infrastructure wireless network using IEEE 802.11 Wi-Fi standard. Since we found in the literature that the mobility of stations can have an impact on the quality of service, we try to remedy to this by implementing a new access category reserved for mobile stations. First we compare the throughput between static and mobile nodes, both connected to a QoS station. Then we propose our new model that consists of adding a new access category used by mobile nodes regardless of their traffic category. The study was made by simulating different scenarios using Network Simulator-3 (NS-3). We found that the throughput may vary depending on the simulation scenario. The simulation results show that with the proposed solution the mobile nodes can have a better throughput.
