Issues on the design of a variable LINC amplifier system in SiGe operating at 2.4GHz
No full textAn increasing number of wireless communication systems require linear transmitters that can achieve high efficiency. Good linearity is necessary for bandwidth efficient modulation while poor efficiency directly affects operational costs and causes thermal losses in the base station. This paper examines the implementation of the outphasing technique, also known as Linear Amplification with Nonlinear Components (LINC) using a 0.25 mm SiGe BICMOS process. Adaptation of the amplifier in order to achieve different power levels, via the use of Class-F amplifying sections working in parallel is also examined. The effects of the input and output mismatch introduced when changing the power level are discussed and possible solutions presented. Furthermore, specific problems which arise when using a bipolar technology are addressed. This work also discusses the adaptation of a tunable phase shifter for a 1 V supply and wide-linear range. The 2.4 GHz amplifier system presented in this work achieved a 3-level power control with a maximum PAE in the range of 58-73
Preemptive type checking in dynamically typed programs
No full textWith the rise of languages such as JavaScript, dynamically typed languages have gained a strong foothold in the programming language landscape. These languages are very well suited for rapid prototyping and for use with agile programming methodologies. However, programmers would benefit from the ability to detect type errors in their code early, without imposing unnecessary restrictions on their programs.Here we describe a new type inference system that identifies potential type errors through a flow-sensitive static analysis. This analysis is invoked at a very late stage, after the compilation to bytecode and initialisation of the program. It computes for every expression the variable’s present (from the values that it has last been assigned) and future (with which it is used in the further program execution) types, respectively. Using this information, our mechanism inserts type checks at strategic points in the original program. We prove that these checks, inserted as early as possible, preempt type errors earlier than existing type systems. We further show that these checks do not change the semantics of programs that do not raise type errors.Preemptive type checking can be added to existing languages without the need to modify the existing runtime environment. We show this with an implementation for the Python language and demonstrate its effectiveness on a number of benchmarks
The Pygmalion-Galatea myth in relation to simulation scenarios in Star Trek
No full textStar Trek has existed since 1966, with a total of 738 hours of viewing time. Like most science fiction, the series frequently alludes to religion or myth but censors such references for the modern world-view by sanitising them with scientific or scientific-sounding explanation. This paper illustrates the depiction of the Galatea-Pygmalion myth in the franchise and relates these to simulation scenarios.peer-reviewe
The image of universities from the point of view of students and high school graudates
No full textIn this article the most important results and conclusions from two surveys are presented. The first one is an internal survey conducted among the students of the University of Wroclaw. The second one is a survey conducted among students of final grades of high schools located in Wroclaw. Both surveys were conducted in the years 2007-2009 on the territory of Wroclaw. Taking into consideration the purposes of this work, we will focus just on the most significant results and conclusions from the conducted surveys. Full set of data is available in a book discussing the results of a survey on self-presentation and the image of non-public higher education institutions (Grech 2010) and in an article discussing the methodology and detailed results of a survey of the image of University of Wroclaw (Grech 2011). The first of the presented surveys was carried out by a group of employees and students of the Institute of
Journalism and Social Communication of the University of Wroclaw, the author of this
article belonged to. The second survey was the effect of a greater own project.
Due to the lack of comparable surveys concerning Polish universities, the survey which is presented in a limited extent in this article is pioneering in character and before reference data for other universities are obtained, it gives a foundation for drawing conclusions about the image of universities in Poland. The obtained results highlight expectations, open and hidden factors determining the choice of a university, praised and negatively assessed elements of a university's image, ideas about other Polish universities, reconstruction of the image of perfect university. The analysis of the collected data shows a few dimensions through which a university is regarded and through which the decision whether to choose this or that university is made. These dimensions are systemic and hierarchical and - depending on the situation other criteria are regarded as important
The image of universities from the point of view of students and high school graduates
No full textW artykule przedstawiono najważniejsze wyniki i wnioski wypływające z dwóch badań. Pierwsze z nich to badanie wewnętrzne przeprowadzone wśród studentów Uniwersytetu Wrocławskiego, drugie to badanie przeprowadzone wśród wrocławskich maturzystów. Oba badania zostały przeprowadzone w latach 2007 - 2009 na terenie Wrocławia. Ze względu na cele niniejszego opracowania autor ograniczył się do najistotniejszych wyników i wniosków wypływających z przeprowadzonych badań. Pełne dane dostępne są w książce omawiającej wyniki badań autoprezentacji i wizerunek uczelni niepublicznych oraz artykule referującym metodologię oraz szczegółowe wyniki badań wizerunku Uniwersytetu Wrocławskiego. Pierwsze z prezentowanych badań zostało zrealizowane przez grupę pracowników i studentów Instytutu Dziennikarstwa i Komunikacji Społecznej Uniwersytetu Wrocławskiego, której autor był członkiem, drugie stanowi efekt większego projektu własnego.
Ze względu na brak porównywalnych badań dotyczących polskich uniwersytetów badanie, którego wybrane wyniki są prezentowane ma charakter pionierski i dopóki nie zostaną uzyskane dane referencyjne dla innych uniwersytetów daje podstawy do wnioskowania o wizerunku uniwersytetu w Polsce. Otrzymane rezultaty wskazują na oczekiwania, jawne i ukryte determinanty wyboru uczelni, cenione i negatywnie oceniane elementy wizerunku uniwersytetu, wyobrażenie o innych polskich uniwersytetach, rekonstrukcję obrazu idealnego uniwersytetu. Analiza zebranych danych wskazuje na kilka wymiarów przez pryzmat których postrzegany jest uniwersytet i podejmowane decyzje o studiach, przy czym wymiary te mają charakter systemowy i hierarchiczny - w zależności od sytuacji inne kryteria uznawane są za istotne.In this article the most important results and conclusions from two surveys are presented.

Carmel Borg and Michael Grech. Lorenzo Milani’s culture of peace : essays on religion, education, and democratic life [Book review]
No full textThe biography and thoughts of Don Milani, and his school, are enriched in this edited work
by approaches from different perspectives. The two editors, Carmel Borg and Michael
Grech, have utilised their strengths in education and philosophy to organise a set of readings
especially focusing on peace with a thrust that becomes a pedagogy and a stance that
is critical not passive. Part I, entitled 'Peace and religion: Then and now' is arguably the most directly related to
themes raised by the Letter to the military chaplains of Don Milani. In the first reading, with
a number of brushstrokes, Borg & Grech depict the Letter's catholic, Italian, and Tuscan
ecclesiastical contexts. Amongst others, a context they describe is the one when the Catholic
Church was ready for a marriage of convenience with Nazism and Fascism, along with their
war rhetoric. [excerpt]peer-reviewe
