This paper deals with the relocation of multi-target Virtual Machines (VMs) in a cloud server farm. The proposed VM movement technique at the cloud server farm meanders VMs from underutilized to full capacity Physical Machines (PMs) to energy-efficient Physical Machines (PMs). Furthermore, the multi-target VMs relocation technique not only reduces the forced use of PMs and switches but also confirms the essence of administration by preserving the SLA at the cloud server farm. A novel energy-efficient hybrid (EEHF) system for enhancing the proficiency of electrical energy usage in data centers is carried out and evaluated in this paper. Instead of focusing on only one approach as in previous related works, the proposed system is truly based on solicitation preparation and worker booking. Until managing the preparation, the EEH system sorts the errand clients’ requests according to their time and force requirements. It has a booking system that takes power use into account when making planning decisions. It also has a precise calculation that determines if under burdened employees should be rested or dozed in overburdened workers, virtual machines that should be floated, and workers that will receive moved virtual machines VMs. When compared to other strategies, our proposed VMs development strategy may find a great balance among three conflict goals. Furthermore, the shroud-based cloud sim test results show that our proposed multi-target VMs relocation strategy outperforms best-in-class VMs movement strategies like the Random VMs relocation system in terms of energy efficiency and SLA penetration at the cloud server farm.

This paper describes the design of an intelligent energy efficient lighting system that uses multi-coloured LEDs and a fuzzy logic controller to produce light of the required luminance level and colour in a typical room space. The lighting system incorporates automatic control of a room’s window shade opening, conveniently harvesting daylight. Appropriate room occupancy sensors were set to dim off the LEDs if there are no people in the room. A movement sensor was also considered for dimming the LEDs if the persons in the room are asleep. A colour decoder was included in the control system, to determine the LEDs’ output light colour and dim them off if the colour requirement is not selected. The colour decoder also closes the window shade if required light colour is not white. Two Fuzzy Logic controllers were used in the system; one to control opening of the room’s window shade via microcontroller, and the other to control the LEDs’ output luminance. The study was limited to simulation of the design in a MATLAB software environment using Fuzzy Logic Toolbox and Simulink blocks. The simulation test results confirmed that the LEDs’ output luminance decreases as the amount of daylight entering the room increases. The designed system intelligently saves lighting electrical energy while maintaining the room’s comfortable illumination levels and colour requirements.

Tracking of public bus location requires a GPS device to be installed, and lots of bus operators in developing countries don't have such an answer in situ to supply an accurate estimation of bus time of arrival (ETA). Without ETA information, it's very difficult for the overall public to plan their journey effectively. In this paper, implementation of an innovative IOT solution to trace the real time location of buses without requiring the deployment of a GPS device is discussed. It uses Bluetooth Low Energy (BLE) proximity beacon to trace the journey of a bus by deploying an Estimate location beacon on the bus. BLE detection devices (Raspberry Pi 4) are installed at selected bus stops along the path to detect the arrival of buses. Once detected, the situation of the bus is submitted to a cloud server to compute the bus ETAs. A field trial is currently being conducted in Johor, Malaysia together with an area bus operator on one single path. Our test results showed that the detection of BLE beacons is extremely accurate and it's feasible to trace the situation of buses without employing a GPS device during a cost-effective way.

More than a year and a half has passed since the first Summit and the Russia-Africa Economic Forum. The crisis of “Western-style” globalization, accelerated by the coronavirus pandemic, has adjusted the formation of the Russian business strategy in the African direction. The most important areas of Russian-African cooperation in the near future are healthcare, ensuring food security, infrastructure projects, including digitalization, education and science. With what results will Russia and Africa approach the next Summit, planned for 2022? Which business strategy will meet both Russian and African interests? What Russian investment projects are already being implemented on the African continent? How are the new mechanism and tools of the Russian-African partnership formed? These and other issues on the Russian-African agenda were discussed at the Russia-Africa business dialogue, which was held on June 3, 2021 as part of the St. Petersburg International Economic Forum. This was the first major Russian African event in full-time format after the historic Russia-Africa Summit and Economic Forum, which was successfully held in Sochi on October 23-24, 2019. The participants in the discussion concluded that Africa needs Russia to achieve the ambitious goals of the Agenda 2063, but Russia also needs Africa to implement the new development strategy of the Russian Federation, which focuses on increasing non-resource exports and technological breakthrough. The African fast-growing market, formed by the youngest population in the world, is showing an increased demand for modern Russian goods and technologies, primarily in such areas as healthcare, agriculture, infrastructure, resource development, and digital products. To intensify cooperation, it is necessary to use the entire set of instruments of public-private partnership, to utilize the information resource at full capacity, and to develop cooperation in the field of science and education. The main thing for us now is to bring our cooperation, including in the economic sphere, to a fundamentally new level that meets the interests of our peoples. Both Russia and Africa have a lot to learn from each other, and our economic strategies can be successfully implemented if we combine our efforts.

Abstract Muxindo’s LED bulb is one of the brands that are widely used by Indonesian people as lighting in the home. This study aims to look at the effectiveness of the light spectrum of the 10, 15 and 20 Watt LED power bulbs as an energy source to generate electrical energy in monocrystalline mini photovoltaic (PV) cell module. The light spectrum is compared with and without the Fresnel lens before being transmitted to the PV surface. The test results show that the PV output power is much better with a Fresnel lens (4.06> 1.67) mW. The efficiency of PV with lens displays slightly different figures, 3.77% at 15 Watt bulb power, while without Fresnel lenses, PV efficiency is 4.86% with a 20 Watt bulb. Need further research, for example, with Philips brand LED bulbs

This research is a development of previous research entitled "Designing Regenerative Shock Absorber as a Vibration Energy Harvesting Tool on Vehicles" in the PUPT scheme funded by PNBP UNP 2017. In this study optimization of design oriented to energy generation was carried out while also paying attention to aspects driving comfort that might change due to the installation of a harvesting energy mechanism. One aspect of the change occurred in the type of magnet used, namely a ring type magnet with a type of neodymium material.From the test results obtained by changing the value of the efficiency of the shock absorber after the ERSA mechanism is installed by 2%, this condition also has an impact on the dissimilarity of the attenuation value obtained by 2% for the front-rear (left) and (right) wheels. In terms of generation voltage obtained the maximum generation voltage obtained is 25,600 mV. Based on the data obtained, it needs further development ERSA, especially in the aspect of the electromagnetic mechanism to optimize the generation of electrical energy.
