The Given

Photovoltaic plants and off-grid connections have been a solution for rural and remote areas in the past few years. It is, however, requiring a group of technicians to maintain the efficiency of the PV panels in a regular based. PV panels also suffer a steady reduction in their effectiveness due to the need for cleaning and environmental aspects. The project monitors the output of individual PV connected in the array and advises timely maintenance. The technology of wireless sensor networks consists of a small device. Efficiency trends are to be utilised to activate the cleaning robot to travels the given path and cleans the suspected PV and then moves to the next one as required

Local government in Iceland has been through extensive functional reforms in the past three decades. Territorial reforms have been less successful even though the central government has openly aimed to enhance the capacity of the local governments. This study aims to estimate the administrative capacity of Icelandic local governments by estimating the level of expertise in the tasks of planning, education and social service. The findings show that there is a considerable difference with respect to size, as municipalities with more than 3,000 citizens have much higher levels of expertise in comparison to smaller municipalities. The municipalities are only partially able to turn to inter-municipal cooperation (IMC) for compensation because the municipalities in more densely populated areas are more likely to set up IMC entities than those in more sparsely populated areas. The municipalities in less populated areas are also more likely to buy their services from private service providers. Moreover, the smallest municipalities have transferred a large bulk of their functions to other municipalities through contracting. The findings suggest that IMCs may not be the best answer for small municipalities, especially those in rural and remote areas.

The way of generating and distributing energy throughout the electrical grid to all users is evolving. The concept of Smart Grid (SG) took place to enhance the management of the electrical grid infrastructure and its functionalities from the traditional system to an improved one. To measure the energy consumption of the users is one of these functionalities that, in some countries, has already evolved from a periodical manual consumption reading to a more frequent and automatic one, leading to the concept of Smart Metering (SM). Technology improvement could be applied to the SM systems to allow, on one hand, a more efficient way to collect the energy consumption data of each user, and, on the other hand, a better distribution of the available energy through the infrastructure. Widespread communication solutions based on existing telecommunication infrastructures instead of using ad-hoc ones can be exploited for this purpose. In this paper, we recall the basic elements and the evolution of the SM network architecture focusing on how it could further improve in the near future. We report the main technologies and protocols which can be exploited for the data exchange throughout the infrastructure and the pros and cons of each solution. Finally, we propose an innovative solution as a possible evolution of the SM system. This solution is based on a set of Internet of Things (IoT) communication technologies called Low Power Wide Area Network (LPWAN) which could be employed to improve the performance of the currently used technologies and provide additional functionalities. We also propose the employment of Unmanned Aerial Vehicles (UAVs) to periodically collect energy consumption data, with evident advantages especially if employed in rural and remote areas. We show some preliminary performance results which allow assessing the feasibility of the proposed approach.

Cleaning Methods

Abstract Traditional grain cleaning methods are labor-intensive, time-consuming, and yet very inefficient. The use of available mechanical seed cleaners is widely limited since they are expensive to own, operate, and maintain. A Pedal Operated Seed Cleaner (PoS-Cleaner) was developed and its performance evaluated. Appropriate engineering principles and methodologies were used in the sizing and construction of the machine. The cleaner consists of a bicycle-like pedaling system, hopper, a centrifugal fan, and three cleaning sieves which include two inside interlocking sieves (one sieve fixed and the other adjustable); whose meshes can be adjusted to be larger than the size of the unclean seeds by longitudinally translating the second sieve to achieve the appropriate seed size. This allows trapping of impurities larger than the seeds. Cleaning rates of 576.5 kg/h, 375.8 kg/h, and 377.4 kg/h for maize, beans, and groundnuts were obtained respectively. Maize, beans, and groundnuts had their highest cleaning efficiencies of 95.09%, 87.61%, and 81.67% at inner sieve sizes of 13 mm, 16 mm and 10 mm respectively, pedaling speed of 60 rpm. The PoS-Cleaner presents a more viable cleaning option for smallholder farmers in rural and remote areas with no access to the national grid, therefore producing high-quality seeds. This will eventually facilitate agricultural value addition and increase individual family incomes in Uganda. Article highlights A pedal operated multi-seed cleaner was developed. Achieved 5 times higher seed cleaning rates compared to traditional cleaning technologies. Attained higher separation efficiencies of seed and externalities compared to traditional technologies.
