No full textAn assessment of the impact of possible CAP reform scenarios on Romanian agriculture
No full textUsing a simplified model, with key-variable the prices of two different possible scenarios of CAP reform after 2013 (moderate and radical), this paper present a comparison between the price effects of implementation of each reform scenario at 2015 horizon on Romanian agriculture. This short analysis shows that, under the presented hypotheses, the net welfare effect, due to the price changes, for the selected products, is positive in both reform scenarios, yet greater in the case of the radical reform. Integrated in the large context of Romanian development, it seems that the influence of CAP reform upon agriculture and rural areas will be most likely a gradual one: an interpenetration between the two scenarios is foreseeable, starting with the moderate reform that will dominate the period around 2013, the reform measures acquiring a more radical character afterwards.CAP reform, Romania, welfare effects, Agricultural and Food Policy,
Rich, Sturmian, and trapezoidal words
No full textIn this paper we explore various interconnections between rich words, Sturmian words, and trapezoidal words. Rich words, first introduced by the second and third authors together with J. Justin and S. Widmer, constitute a new class of finite and infinite words characterized by having the maximal number of palindromic factors. Every finite Sturmian word is rich, but not conversely. Trapezoidal words were first introduced by the first author in studying the behavior of the subword complexity of finite Sturmian words. Unfortunately this property does not characterize finite Sturmian words. In this note we show that the only trapezoidal palindromes are Sturmian. More generally we show that Sturmian palindromes can be characterized either in terms of their subword complexity (the trapezoidal property) or in terms of their palindromic complexity. We also obtain a similar characterization of rich palindromes in terms of a relation between palindromic complexity and subword complexity

System-on-chip Computing and Interconnection Architectures for Telecommunications and Signal Processing
No full textThis dissertation proposes novel architectures and design techniques targeting SoC building blocks for telecommunications and signal processing applications.
Hardware implementation of Low-Density Parity-Check decoders is approached at both the algorithmic and the architecture level. Low-Density Parity-Check codes are a promising coding scheme for future communication standards due to their outstanding error correction performance.
This work proposes a methodology for analyzing effects of finite precision arithmetic on error correction performance and hardware complexity. The methodology is throughout employed for co-designing the decoder. First, a low-complexity check node based on the P-output decoding principle is designed and characterized on a CMOS standard-cells library. Results demonstrate implementation loss below 0.2 dB down to BER of 10^{-8} and a saving in complexity up to 59% with respect to other works in recent literature. High-throughput and low-latency issues are addressed with modified single-phase decoding schedules. A new "memory-aware" schedule is proposed requiring down to 20% of memory with respect to the traditional two-phase flooding decoding. Additionally, throughput is doubled and logic complexity reduced of 12%. These advantages are traded-off with error correction performance, thus making the solution attractive only for long codes, as those adopted in the DVB-S2 standard. The "layered decoding" principle is extended to those codes not specifically conceived for this technique. Proposed architectures exhibit complexity savings in the order of 40% for both area and power consumption figures, while implementation loss is smaller than 0.05 dB.
Most modern communication standards employ Orthogonal Frequency Division Multiplexing as part of their physical layer. The core of OFDM is the Fast Fourier Transform and its inverse in charge of symbols (de)modulation. Requirements on throughput and energy efficiency call for FFT hardware implementation, while ubiquity of FFT suggests the design of parametric, re-configurable and re-usable IP hardware macrocells. In this context, this thesis describes an FFT/IFFT core compiler particularly suited for implementation of OFDM communication systems. The tool employs an accuracy-driven configuration engine which automatically profiles the internal arithmetic and generates a core with minimum operands bit-width and thus minimum circuit complexity. The engine performs a closed-loop optimization over three different internal arithmetic models (fixed-point, block floating-point and convergent block floating-point) using the numerical accuracy budget given by the user as a reference point. The flexibility and re-usability of the proposed macrocell are illustrated through several case studies which encompass all current state-of-the-art OFDM communications standards (WLAN, WMAN, xDSL, DVB-T/H, DAB and UWB). Implementations results are presented for two deep sub-micron standard-cells libraries (65 and 90 nm) and commercially available FPGA devices. Compared with other FFT core compilers, the proposed environment produces macrocells with lower circuit complexity and same system level performance (throughput, transform size and numerical accuracy).
The final part of this dissertation focuses on the Network-on-Chip design paradigm whose goal is building scalable communication infrastructures connecting hundreds of core. A low-complexity link architecture for mesochronous on-chip communication is discussed. The link enables skew constraint looseness in the clock tree synthesis, frequency speed-up, power consumption reduction and faster back-end turnarounds. The proposed architecture reaches a maximum clock frequency of 1 GHz on 65 nm low-leakage CMOS standard-cells library. In a complex test case with a full-blown NoC infrastructure, the link overhead is only 3% of chip area and 0.5% of leakage power consumption.
Finally, a new methodology, named metacoding, is proposed. Metacoding generates correct-by-construction technology independent RTL codebases for NoC building blocks. The RTL coding phase is abstracted and modeled with an Object Oriented framework, integrated within a commercial tool for IP packaging (Synopsys CoreTools suite). Compared with traditional coding styles based on pre-processor directives, metacoding produces 65% smaller codebases and reduces the configurations to verify up to three orders of magnitude
Cultural Policy against the Grain 流れに逆らう文化政策: liber amicorum for Matthias Theodor Vogt in honour of his 65th birthday, edited by his colleagues and students
No full textWhat are the premises of today‘s cultural policy? What insights can the past, present and theory offer for a contemporary cultural policy? How can art counteract agoraphobia, digital isolation and populist temptations? How can local authorities give their citizens ample space to develop civil society solidarity ‘for the good of the city. For only when the city is well will you be well.’ (It should be noted that Jeremiah 29:7 addresses immigrants who are to become citizens in foreign Babylon. Does our cultural policy also achieve this?) Are the arts not precisely the place where we can first listen to the other before we think together and then act together?It is the historical achievement of Matthias Theodor Vogt, in the Free State of Saxony, which was re-established in 1990, to not only conceive the Saxon Cultural Area Act between 1991 and 1995 in a unique process of analysis and dialogue with the state, municipal and civil society levels, but also to have it enshrined in law and, last but not least, to have it implemented with little friction. It was therefore only natural that, on the thirtieth anniversary of the law‘s entry into force, the cultural areas of Saxony invited Matthias Theodor Vogt‘s colleagues and students to a conference entitled ‘Kulturpolitik gegen den Strich’ (Cultural Policy Against the Grain). We are hereby presenting the results of this conference in a commemorative publication to mark his 65th birthday.What can art do better and differently than the digital world? What political, structural, economic, and, last but not least, intellectual conditions are necessary for art to develop its own life for the benefit of humanity? The cover image shows Haus Klingewalde, Görlitz, home of the Institute for Cultural Infrastructure Saxony since 1998. The watercolour by Lynne Beal, Cologne, relates to a conversation with Matthias Theodor Vogt about the vanishing point in Alberti: De pictura | De pittura (1435 – 1436). According to Corinna Laude, in the centricus punctus of Alberti‘s intromission theory, ‘the orthogonal vanishing lines, the depth lines of the representation, converge “quasi persino in infinito” (as it were out into infinity), it lies in infinity – and thus, according to contemporary understanding, in God’. Which “vanishing points” does today‘s post-secular society use?How can political science in Chemnitz interact in a multidisciplinary, cross-continental manner, always with reference to human beings themselves, with cultural studies in Tokyo and linguistics in Leipzig, with legal studies in Naples and social sciences in Rome? This volume shows that cultural policy studies require a fact-based holistic approach and that this may be achieved by working together.:Bingen, Dieter (Köln), Stefan Garsztecki (Chemnitz), Goro Christoph Kimura (Tokyo), Luigi Ferrara (Neapel), Peter Lah (Rom), Beat Siebenhaar (Leipzig) and the other editors: Listening, Considering, Acting, Introduction by the editors
