Joint Compensation of I/Q Impairments and PA Nonlinearity for Concurrent Dual-Band Transmitters using Two-Box Model

A novel two-box model for joint compensation of nonlinear distortion introduced from both in-phase/quadrature modulator and power amplifier is proposed for concurrent dual-band wireless transmitters. Compensation of nonlinear distortion is accomplished in two phases, where phases are identified separately. It is shown that complexity of the digital predistortion is reduced. The performance of the proposed model is evaluated in terms of ACPR, EVM and NMSE improvements using 1.4 MHz LTE and WCDMA signals.

Skolad blick på blommor : Formandet av yrkeskunnande i floristutbildning

This article-based thesis focuses on the formation of vocational knowing within adult and upper secondary floristry education in Sweden. Three articles explore classroom interaction and assessment actions; a fourth considers changes in vocational subject matter during the period 1990–2015. While the first three articles draw on empirical data in the form of video and audio recordings in combination with participant observation, the fourth is based primarily on material-based interview data. All four articles share a sociocultural perspective on educational practice (Wertsch, 1998; Säljö, 2011, 2013) and a relational view of knowing (e.g., Carlgren, 2015; Molander, 1996), in combination with the use of conversation analysis (Goodwin & Heritage, 1990; Sahlström & Melander, 2010) as a tool to illuminate the formation of vocational knowing. The interaction between teacher, student, and floral arrangement is foregrounded to facilitate analysis of the formation of vocational knowing. The results contribute to our understanding of the schooling of the gaze (Goodwin, 1994; Grasseni, 2009, 2011) as appropriated by participants in the interaction. Floristry vocational knowing is shown to evolve in the temporal dimension, encompassing (a) financial and aesthetic values, (b) verbal and non–verbal communication, (c) botanical material and tools, and (d) making. The respective roles and interrelations of these four components of vocational knowing in floristry are discussed. The contribution of the thesis is twofold. First, these articles contribute to the understanding of vocational education through close appraisal of the formation of vocational knowing. Second, in exploring the previously under-researched field of Swedish floristry vocational education, the thesis bridges a gap in existing knowledge of the evolution of Swedish vocational education. As floristry education is little researched internationally, the thesis also contributes to the wider body of international research. 

Käyttöpääoman ennustaminen kysyntäennusteen avulla

Työn tavoite on selvittää erilaisia käyttöpääoman ennustusmalleja, jotka pohjautuvat kysyntäennusteeseen. Tavoitteena on esittää malleja niin pitkän kuin lyhyenkin aikavälin ennustamiseen. Pitkällä aikavälillä mallien on tarkoitus ennustaa yrityksissä sitoutuvan käyttöpääoman kokonaistarvetta, kun taas lyhyen aikavälin malleilla pureudutaan käyttöpääomaerien (lopputuotevarasto ja myyntisaamiset) ennustamiseen tuotekohtaisesti. Työssä pyritään myös vastaamaan, miksi käyttöpääomaa kannattaa ennustaa ja miten sen hallintaa voidaan tehostaa. Työ on toteutettu kirjallisuuskatsauksena, mitä on elävöitetty laskuesimerkein. Laskuesimerkkien tarkoitus on antaa lukijalle kuva käyttöpääoman ennustamisen todellisista mahdollisuuksista, jotta työ ei jäisi pelkäksi sanahelinäksi. Työssä esitetyt ennustusmallit on valittu matemaattisen yksinkertaisuutensa ehdolla, jotta niiden käyttäminen yritysmaailmassa olisi mahdollista. Käyttöpääomatarpeen ennustamisen suurimpana haasteena voidaan pitää kysyntäennusteen luotettavuutta. Vuositasolla käyttöpääomatarpeen keskimääräinen osuus suhteessa liikevaihtoon on helpohko ennustaa liiketoiminnan pysyessä melko vakiona. Tarve voi kuitenkin vaihdella hyvin paljon kysynnän vaihdellessa kuukausi-, viikko- ja päivätasolla. Jos kysyntäennustetta saadaan tarkennettua, lopputuotevaraston kokoa ja siihen sitoutuvaa käyttöpääomaa on mahdollista pienentää, koska varmuusvaraston määrittelyssä käytettävä hajonta pienenee. Myyntisaamisten osalta lähitulevaisuudessa sitoutuvaan käyttöpääomaan vaikuttaa eniten asiakaskohtainen maksukäyttäytyminen, koska myyntisaamisiin vaikuttava kysyntä on suurimmalta osaltaan jo toteutunut.

Vem ouvir o verso de teu cantador : amos, cantadores e toadas no Boi-Bumbá Caprichoso Belém/PA

This thesis aims to investigating the cantadores and the toadas in the Boi Bumbá, debating questions which put together around the construction and performance of amo s and cantador s role in the Boi Bumbá Caprichoso of Belém-PA city and exploring the extent of toadas its characteristics, functions, the uses that are made of theirs and the relations that establishes between them and the cantadores. The problematic of the research consisted on analysing what the amos, cantadores and toadas represent in the whole context of boi-bumbá plays in Belém, nowadays. Considering this perspective, I tried to identify on Boi Caprichoso the most meaningful expressions which were related to toadas and how the roles of amo and cantador were performed. Participative observation, ethnical research, open and semistructured interviews were used as research methods. The role performances on Boi Caprichoso plays an essential part on the playing realization, highlighting themselves as pivotal characters. These performances, characterized by the vocal presence, also highlighted the size that toadas occupy in the whole play, and pointed the way for an emerging model of presentation, in which both toada and cantador appear as central figures

Un estudio de Alicia en el pa?s de las maravillas y Alicia a trav?s del espejo con un enfoque en la ense?anza de las matem?ticas

Cuando se ense?an las matem?ticas se debe tener claros los conceptos que se abordar?n en la clase, pero no se puede dejar de lado que dichos conceptos surgieron en un momento hist?rico y que fueron construidos por estudiosos de las matem?ticas bajo un contexto determinado, lo cual sirve para conocer el por qu? surgieron las matem?ticas, para qu? que se ense?an en la escuela, qu? se debe ense?ar y qu? esperan los estudiantes aprender, debido a que constantemente se preguntan si las matem?ticas les servir? de algo en su d?a a d?a. Las matem?ticas se van construyendo y se enriquecen de nociones, muchas veces expl?citas como bien se conoce, o en otras impl?citas como es el caso que se observa en diversas obras literarias. Espec?ficamente, en este trabajo se abordar?n algunos cap?tulos de dos libros que parecen ser solo para un p?blico infantil, se trata de ?Alicia en el pa?s de las maravillas? y ?Alicia a trav?s del espejo?, escritos por un matem?tico ingl?s de la ?poca victoriana, Charles Lutwidge Dodgson, m?s conocido en la literatura como Lewis Carroll. Pues bien, para poder comprender estas dos obras desde la mirada matem?tica, se hizo necesario partir no solo del desarrollo matem?tico de la Inglaterra victoriana, sino tambi?n conocer una edici?n comentada de las obras por parte del autor Manuel Garrido y desde la filosof?a del lenguaje, por lo cual se tomaron como referente los trabajos del fil?sofo Jairo Urrea Henao quien a su vez menciona varios fil?sofos que han realizado un estudio de las obras de Carroll, dado que es a trav?s de los juegos del lenguaje y la noci?n de la l?gica del sinsentido donde se pueden evidenciar algunas nociones matem?ticas de la ?poca del reverendo Dodgson, para aportar reflexiones educativas desde la literatura hacia la ense?anza de las matem?ticas en el bachillerato.

Od transfromacji do integracji: wybrane uwagi nt. “bezpośredniej” partycypacji obywateli w procesie podejmowania decyzji politycznych po 1989 r. na przykładzie państw Grupy Wyszehradzkiej

The subject of this paper concerns selected experiences of citizens from the Visegrad Group countries (Poland, the Czech Republic, Slovakia and Hungary) participating in the process of ‘direct’ (that is, exercised by means of the tools of direct democracy) decision making as regards the most important matters, ranging from those related to the process of political transformation to the decision on accession to the European Union. The present considerations dwell on the experiences of Central and East European countries.

Il «Castellazzo» di Monte Iato in Sicilia occidentale (PA) Quinta e sesta campagna di scavo. Aggiornamenti dal territorio

From May 15th to 30th and 15th to 30th September 2015 took place the fifth and sixth excavation campaign at the Castellazzo of Monte Iato. The presence of 15 participants made it possible to deepen the research significantly and ex-pand the surface area of investigation. It is completely emptied a room already identified in previous campaigns and provided new information about the relationship with the existing cemetery. Part of a burial in a supine position was destroyed by the installation of wall 20. Traces of another turret projecting from the walls have been discovered in the east and another section of the inner walls (15) was fully exposed. A gate, between two towers, is the first entry traced so far, on the north-eastern side of the plateau. The archaeological materials found confirm the characteristics and type of construction. Being a military camp of ephemeral nature, although active at least 30 years, objects such as arrowheads and crossbow quarrels, knives, buckles and harnesses for horses have been found. One of the environments has been interpreted as an area where gaming took place because of the presence of four dice in ivory, glasses and different coins, in addition to the greater extent than the other environments found. Among the findings are reported a glass weight with a cufic inscription dated to the mid-twelfth century and two bronze coins dated in 15th centu-ry.

Avaliação nutricional de estudantes do Instituto Politécnico de Santarém

O estudo apresentado avaliou a adequabilidade da ingesta de nutrientes e energia de estudantes do Instituto Politécnico de Santarém (IPS), através do preenchimento de um relatório alimentar de 24 horas, preenchido on line. Foram obtidas 103 respostas válidas para avaliação, maioritariamente do género feminino (77%), com uma idade média de 21 anos e valores de IMC normoponderais (78%). Cerca de metade dos participantes apresentou um estilo de vida sedentário. No geral, a alimentação caracterizou-se por elevados consumos de arroz, massa, batatas ou cereais de pequeno-almoço, de carne ou ovos, e consumos reduzidos de peixe, leguminosas e hortícolas crus ou cozinhados. O consumo de frutos e vegetais foi maioritariamente inferior ao recomendado, assim como a ingesta de energia e fibra. Ao contrário, a ingesta de lípidos totais e lípidos saturados foi superior ao recomendado na maioria dos participantes. A prevalência de inadequação de micronutrientes como cálcio, vitamina A, vitamina C e folatos foi próxima dos 50% ou superior. Perante os dados obtidos sugere-se uma melhoria dos hábitos alimentares e de estilo de vida, nomeadamente, o aumento do número de refeições realizadas, o aumento do consumo de frutos, hortícolas e leguminosas e o aumento da prática de atividade física.

Teoretycznoprawne aspekty operacjonalizacji ochrony praw człowieka w państwie z perspektywy globalnego systemu prawa (Zarys problematyki)

The article is devoted to the presentation of the outline of the concept of operationalization of human rights taking place in the states involved in the system of international protection of those rights. The concept of operationalization of protection is a collective term for a series of processes that lead to the establishment of legal provisions protecting human rights, and to transfer this abstract construct to specific societies. It includes both the decision-making processes of extralegal (uprising idea, its conceptualization, social issues and change the perception of axiology of society, cultural aspects) and legal (lawmaking and law application processes in the aspect of human rights and the impact of international institutions on them) character. The essence of the process of operationalization is providing effective protection of human rights in a state. The concept is set primarily on the consequences of membership of Poland in the system of the Council of Europe.
