Modelling and Simulation of a Grid-Connected PV System based on Efficient Maximum Power Point Tracking Algorithm
No full textThe results presented in this paper have been acquired through simulation of a grid-connected photovoltaic system (GCPV) to a specific section of Alsabyia generation station part of Kuwait national grid with efficient maximum power point tracking (MPPT) algorithm incorporated into a DC-DC boost converter. The simulations were performed using Power Simulation Software (PSIM). The analytical model of a photovoltaic (PV) module has been combined with a 'perturb and observe' (P&O) method so that MPP is achieved with the external temperature and solar radiation (SR) also considered. A DC-AC inverter is used to track the output voltage of the converter and interface the PV array with the grid. The results show that the model not only achieves the MPP function but also improves the output of the inverter by reducing the ripples in the sine waveforms

Solaris and the Dao: The Reception of Stanislaw Lem’s Novel in the Sinophone World
No full textThe most popular science fiction novel written by the Polish author Stanisław Lem, Solaris, was published in 1961. Although it was translated into English as early as 1970, the book was unknown to the Sinophone readers until 2003, when the first translation from English into Chinese was published, most probably following the popularity of the resounding Hollywood film adaptation from 2002. Still, Suolalisi Xing (which can be translated as ‘Solaris Star’) did not attract broader audiences in China or Taiwan, at least not until the third version of the novel, translated directly from Polish into Chinese, saw the light of day in 2010. The appearance of this translation coincided with the beginning of a New Golden Era of Chinese and Taiwanese science fiction, which undoubtedly had a significant influence on the positive re-reception of Solaris. In the paper, the author focuses on the philosophical aspect of Lem’s work and investigates which themes and concepts present in Solaris caught the imagination of Chinese-speaking readers. The author wants to show how this reception, while coming from a different historical, cultural, and linguistic background, can enrich our understanding of the novel and introduce a new way of looking at the important existential questions stated by the writer.The most popular science fiction novel written by the Polish author Stanisław Lem, Solaris, was published in 1961.

Berkeley na Solaris
No full textThe article, discussing confirmed in Dialogues, Solaris and Futurological Congress examples of the reception of George Berkeley’s philosophy in Lem’s oeuvre draws attention to the connection between his theories and modernist practice of painting. Berkeley’s observations on perception refer to formal solutions of impressionism and cubism, while his conclusions on immaterialism refer to postulates of suprematism and conceptualism.
The author noticing in Solaris’s landscape iconography which refers to the Avant-garde of the twentieth century proves that it looks like that indirectly due to Lem’s interest in Berkeley and his theory of vision. Descriptions of “mimoids” (impressionism, informel) and symetriads (cubism) seem to prove this thesis directly, while indirectly it is done by selective ideas of Berkeley and parallel reflections of Lem. A conclusion drawn from that on the matter of Berkeley’s correspondence with the twentieth-century painting Avant-garde is confirmed by the comparison of his ideas with subject matter of Rudolf Arnheim and phenomenology
Job at the Space Station: Carnality, Memory and Onirism in Stanisław Lem's Solaris
No full textArtykuł traktuje o tym, jak temat cielesności, pamięci i snu wpływa na lekturę Lemowskiej Solaris. Rozpoczyna się od ukazania powieści jako tekstu wielointerpretacyjnego i otwartego, następnie przechodzę do kwestii innowacyjności modelu Obcego zaprezentowanego przez Lema. Problemy związane z ciałem, pamięcią i snem generuje w tekście postać Harey: będąca sobowtórem dawno zmarłej narzeczonej głównego bohatera zostaje odtworzona na Solaris poprzez wspomnienia Kelvina. Staram się odpowiedzieć na pytanie, czy kobietę można nazwać istotą ludzką oraz co o tym decyduje. Biologia? Czyn nacechowany etycznie? Opisuję także rolę pamięci w zmianie zachodzącej w głównym bohaterze oraz wspominam o intertekstualnym tropie, jakim jest Kochanka Szamoty Stanisława Grabińskiego.This article discusses how the subjects of carnality, memory and dreams influence the reading of Lem's Solaris. The article starts with a discussion of the novel as an open text allowing for multiple interpretations, then it moves on to the innovation of the Alien model presented by Lem. The problems related to body, memory and sleep are generated in the text by the character of Harey, the double of the protagonist's long dead fiancée recreated on Solaris through Kelvin's memories. The author tries to answer the question of whether the woman can be called a human being and what exactly determines that − biology, or an act that is ethically marked? The article also describes the role of memory in the protagonist's internal metamorphosis, as well as mentioning the intertextual trope of Kochanka Szamoty by Stanisław Grabiński
EU-SOLARIS: The European Research Infrastructure Consortium for CSP Technologies
No full textAfter many years of fruitful collaboration in the field of research infrastructures (RIs) for concentrated solar power/solar thermal energy applications, several European countries decided to apply to the European Commission to go a step forward and create a European Research Infrastructure Consortium (ERIC), a new legal form of association which poses a number of advantages in the endeavour for a further development of this technology in Europe at all levels.
This new consortium, EU-SOLARIS ERIC, is likely to be legally implemented in October 2022, after a long negotiation and evaluation process, where the support of the respective Governmental research agencies of the countries involved has been crucial.
EU-SOLARIS ERIC will be a legal entity and its main goal will be the improvement of the interoperability, accessibility and quality of services provided by the existing European research infrastructures to the CSP/STE research communities and industrial stakeholders.
Although the current Members of the EU-SOLARIS consortium are Germany, France, Cyprus and Spain (Statutory Seat at Plataforma Solar de Almería, Spain), plus Portugal as an Observer, it is open to any other country willing to participate as Member or Observer
THE EUROPEAN SOLAR RESEARCH INFRASTRUCTURE FOR CONCENTRATED SOLAR POWER (EU-SOLARIS)
No full textEU-SOLARIS aims to create a new legal entity to explore and implement new and improved rules and procedures for reserach infrastructures (RI) for Solar Thermal Electricity (STE) technology, in order to optimise RI development and RTD coordination. According to what was communicated by ESFRI, EU-SOLARIS is expected to be the first of its kind, where Industrial needs and private funding will play a significant role.
15 partners (13 Scientific,1 Ministry and the EU STE Industry Assoc.) representing 11 EU countries are participating covering all the modes and Technologies of Solar Energy Concentrating Systems.
The success of this initiative-specifically addressed during the PP-will be the establishment of a new governance body, aided by sustainable financial models. The following actions will be included: developing and determining all necessary arrangements for hosting the new legal entity; developing the collaborative model between public and private entities and fostering the collaboration between industry and research centres; establishing one access point and clear rules for users; preparing all the necessary mechanisms to secure sustainable financial resources; defining appropriate systems for knowledge and IPR management; coordinating the efforts of the participating infrastructures around Europe; establish joint future development of research facilities; elaborating effective rules for the dissemination of project; and finally assessing the impact of the new EU-SOLARIS RIs and the deployment of STE technologies for a sustainable development.EU, Funded under: FP7-INFRASTRUCTURES-2012-
Truth is Stranger than Science Fiction: The Quest for Knowledge in Andrei Tarkovskii’s Solaris and Stalker
No full textThis article explores Andrei Tarkovskii’s conception of truth in Solaris (1972) and Stalker (1979) as part of his wider philosophical project concerning knowledge. The director’s epistemological views form a core dimension of his life and aesthetic as he strives towards what he considers a higher, spiritual ‘idea of knowing’. In his search for this idealised notion of truth, Tarkovskii uses the medium of film to address what he perceives as a profound imbalance in modern civilization between scientific rationalism and spiritual/aesthetic ‘truth’. This is nowhere more prominent than in his two science fiction films, Solaris and Stalker, as he uses the genre as a battleground to discuss key debates in epistemology. Comparisons will be made with the Russian author and thinker Tarkovskii most revered, Fyodor Dostoevskii, and the Soviet-period science fiction authors whose works he adapted, Stanisław Lem and the Strugatskii brothers, in order to elucidate how the director came to cinematically represent his philosophy
Solaris Project : The Design of a Solar Powered UAV
No full textProject Solaris is a unique student project that is carried out at Mälardalen University, Sweden. The project involves all the phases of the development and construction of a solar-powered UAV (unmanned aerial vehicle), where every subproject involves a specific assignment in the development-process. The primary task of this project is the investigation of the energy balance for the entire aircraft. In other words, calculating the power that is generated through the solar panels, and the required power to fly the aircraft and operate all the electronic systems. The total thrust from the motors is 6,6 oz (1,834 N) which is completely sufficient to fly the aircraft during cruise-flight and take-off flight. And the provided energy from the solar panels (87,8381 Wp) is enough to operate the motors and the necessary system, including the battery-charging. As a result of these factors, the aircraft will theoretically have the ability to fly “constantly” without the need of landing. The presented data shows the capacity of the aircraft and all the essential parameters. The calculations have been based on the solar-powered UAV Zephyr Qinetiq, due to the fact that Zephyr successfully have managed to fly both day and night. However, the design of the Solaris aircraft has been a little different, regarding the battery and motor choice. But it’s also important to understand that the installation of the exact same components is not fully necessary to achieve the same goal, which is a 24h-flight
Implementation of a Hardware/Software Platform for Real-Timedata-Intensive Applications in Hazardous Environments
No full textReal-Time Technology and Applications Symposium. Brookline, MA, USA, 10-12 Oct. 1996In real-time data-intensive applications, the simultaneous achievement of the required performance and determinism is a difficult issue to address, mainly due to the time needed to perform I/O operations, which is more significant than the CPU processing time. Additional features need to be considered if these applications are intended to perform in hostile environments. In this paper, we address the implementation of a hardware/software platform designed to acquire, transfer, process and store massive amounts of information at sustained rates of several MBytes/sec, capable of supporting real-time applications with stringent throughput requirements under hazardous environmental conditions. A real-world system devoted to the inspection of nuclear power plants is presented as an illustrative examplePublicad
