Over the past few decades the World has experienced a revolution in Energy production from solar technology, mostly from photovoltaics. On the other hand, an increasing number of unmanned aerial vehicle (UAV) applications are also noticed. Combining photovoltaics and UAVs reveals many opportunities for researchers and renewable energy industry. Responding to the challenge of large area observations at remote locations, the conception of an autonomous photovoltaic station integrated with UAV has been proposed. The essential advantage of the station is its energetic autonomy. The station is movable and can be installed in various locations all over the World. It can be implemented for a wide range of applications, i.e. examining hydroelectric, solar or wind power stations. The simulation results of energy production from PV system mounted on the station have been shown in this work. Several issues were taken into account for the calculations: tilt and azimuth of PV modules, irradiation at case study location and energy demand of the station’s equipment. The energy usage of five and eight hours daily of UAV flights was estimated. Energy balance was calculated.

Chapter 5 turns to the transformation of historic spaces into ‘cultural shopping streets’, divided along the official macro-categories of Malays, Chinese, and Indians. After introducing the making of Little India and the Malay Bazar Ramadan, the chapter focuses on the Chinatown-like Jonker Walk as the first and most successful of these projects. This case study shows how these tourism packages resist a wide range of critics: from UNESCO-related actors and local heritage bureaus that condemn the commercialization of these historic streets, to the residents and heritage aficionados that identify them as symbols of multicultural coexistence. This chapter reveals competing views of Melaka’s multi-ethnic townscape: from the cosmopolitan character of the World Heritage inscription to a racialized and politicized demarcation of space.

Performance ratio is one of the indicators used to describe the effectiveness of the PV systems. The sustainability of the PV system year after year as well as its reliability can be checked by measuring the performance ratio each year. This indicator will also enable us to carry out a comparison between the performances of different PV systems. In this paper, the performance ratios for five PV systems installed on the roof tops of some of PTUK university buildings have been calculated on monthly and yearly basis. The analysis has been carried out using the available data (energy production and solar irradiation) for the year 2019. It was found that the performance ratio has higher values for May and September in comparison with other months. On the other hand, its lowest values were obtained in winter months. This trend can be observed for all of the PV clusters on the five buildings.  When taking into account the overall system, the highest value for the performance ratio was 0.89, which was for September, whereas its lowest value of 0.70 was obtained in January. The performance ratio, which was calculated on yearly basis for the overall system, was found to be 0.80. When considering each building separately, the lowest value was 0.44 for the “Services” building whereas the highest value was 0.94 for the Science building.

Disadvantaged Neighbourhoods

Fuel poverty rates are high in southern Europe, particularly in social housing, despite the enormous potential for capturing solar power inherent in the roofs of apartment buildings. The in situ generation, distribution and consumption of photovoltaic energy carry obvious advantages including vastly improved efficiency attendant upon the reduction in distribution-related losses and costs, and the energy empowerment afforded lower income communities. The primary drawback is the imbalance between photovoltaic production patterns and users’ actual needs (peak consumption vs. peak generation). That mismatch is difficult to reconcile without resorting to energy storage or net metering, both of which entail grid involvement and greater management complexity. The present study introduces a methodology for analysing residential archetypes to determine the values of the parameters essential to optimising photovoltaic energy production and use. The aim is to determine where excess generation can be shared with other users in the vicinity and optimally pool residential rooftop facilities to meet community-scale energy demand, ultimately enhancing such disadvantaged neighbourhoods’ self-sufficiency. The case study discussed defines archetypes for just such a neighbourhood in Madrid, Spain. The solar energy production potential of the example is promising for its application in large southern European cities, with self-sufficiency rates obtained ranging from 15% to 25% and self-consumption rates from 61% to 80%.

The study deals with the socio-economic geographical analysis of the solar energy production — one of the most rapidly developing industries of the world energy complex. The aim of the study is to identify and explain main features of the territorial structure of solar energy production and assess its role and place in the world. The paper also investigates the factors that affect the development of solar energy production itself as well as the deployment of individual solar panels or solar power stations. The study carried out is based on the review of datasets and official documents which enable to draw a conclusion that the result of an intensive development of solar energy production is its dynamic spatial expansion visible in the emergence of new poles of growth which largely changes the territorial structure of the industry, transforming it from a monocentric to polycentric.

Cultural diplomacy is an influential element of soft power. The concept covers a wide range of activities that aim to promote national interests through strengthening relationships and enhancing sociocultural cooperation among countries. Cultural diplomacy is built upon the culture, identity, and values of the country. As government apparatuses often activate cultural diplomacy, it is civil society that plays the most prominent role. This study takes Indonesia`s diplomacy as a case study to highlight the importance of cultural diplomacy as a soft power instrument. The study seeks to identify the challenges in the creation of a grand narrative of Indonesia’s cultural diplomacy. Finally, the study argues that in the age of globalization in which the world is moving toward a global culture, Indonesia`s cultural diplomacy concept that is rotating around its unique culture, identity and values needs to be reassessed to not only contain unique Indonesian cultural products, but also contain the spirit of the culture, values, and traditions of the Indonesian people who have sustained the unity of Indonesia.

The article discusses the dialogue of ethnocultures within the anthology titled ‘Contemporary Literature of Russia’s Peoples. Poetry’. The case study of contemporary Russia’s literary processes through works of Kalmyk and Tuvan poetry makes it possible — to a certain degree — to identify its present-day state, examines the existing literary contacts and interrelations, including by means of Russian-language literary translations of compositions by national poets, reveals the translation problem faced by national literatures of our country. Goals. The article presents poetic collections of Kalmyk and Tuvan poets, reveals ethnic worldviews of the Turko-Mongolic peoples through the use of Russian translations. The novelty of the work lies in the fact that this is the first study of Kalmyk and Tuvan poetic lyrics in the format of a modern anthology of literature of Russia’s peoples as a presentation of ethnic poetry for a wide range of Russian-speaking readers. Materials and 57 Фольклористика и литературоведение Methods. The comparative method delineates specific features of Kalmyk and Tuvan poetic works, identifies mental and individual vectors of authors. In terms of gender, the anthology contains works by Kalmyk men poets only. Kalmyk poetry is represented by 5 authors, Tuvan poetry — by 3 authors. The distinctive line is the age. The selected works include none by representatives of senior or junior generations which evidently attests to the fact, on the one hand, there is a problem of generational change and, on the other hand, the compilers faced quite a challenge when it actually came to select authors to be introduced in such anthologies. In genre perspective, both the sections seem to have little to do with the traditional poetic structures and patterns; so, there are some borrowed genres of ballad and poetic legend without any mention of post-modernist experiments. Still, the thematic landscape is traditional enough: motherland, genealogies, national history, nature of ancestral lands, love, and family. The Tuvan poems by E. Mizhit are published in the author’s translations (a bilingual poet), works by the other poets — in V. Kulle’s translations. Results. The study of modern Kalmyk and Tuvan poetry in this book in a comparative aspect reveals similarities and differences in cultures of the Turko-Mongolic peoples, artistic pictures of the world inherent to related ethnic groups.

The list of photovoltaic (PV) applications grows longer every day with high consideration for system efficiency. For instance, in spite of many recent PV aircraft designs, aircraft propulsion was mainly reserved for nonelectric motors. Lately, the Solar Impulse flight across the world shows the possibilities of larger PV powered electric aircraft. In order to obtain this goal efficiency of flight, PV conversion, power converters and electric drives have to be maximized. These demands led to a 63.4 m wingspan. The purpose of this paper is to present that PV power could be used for improving the performance of fixed-wing radio-controlled aircrafts with smaller wingspans (1 m). In order to improve the performance of battery powered electric unmanned aerial vehicles (UAV), a model without PV cells (commercial Li-ion battery powered UAV) was compared with UAV powered both from battery and PV modules. This work shows details about Boost DC/DC converter and PV system design for small size fixed-wing electric UAVs, investigating the possibility of the application of PV powered drones, as well. Theoretical findings involving efficiency improvements have been confirmed by measurements combining the improvements in electrical engineering, microcontroller application and aerodynamics.
