Modern computing system applications or workloads can bring significant non-uniform temperature gradient on-chip, and hence can cause significant temperature uncertainty during clock-tree synthesis. Existing designs of clock-trees have to assume a given time-invariant worst-case temperature map but cannot deal with a set of temperature maps under a set of workloads. For robust clock-tree synthe...

A multilingual, multimodal speech teaching and training system has been developed for 5-10 years old speech handicapped children, in the frame of the SPECO Project, funded by the EU (Contract no. 977126) in 1999. During the training the patients see the speech pictures of the reference speech and listen to the sound of it at the same time. Thus they use the human visual and auditory feedback du...

The prime and primitive spectra of Oq(kn), the multiparameter quantized coordinate ring of affine n-space over an algebraically closed field k, are shown to be topological quotients of the corresponding classical spectra, specO(k) and maxO(k) ≈ k, provided the multiplicative group generated by the entries of q avoids −1.

Let σ , θ be commuting involutions of the connected semisimple algebraic group G where σ , θ and G are defined over an algebraically closed field k, char k = 0. Let H := Gσ and K := Gθ be the fixed point groups. We have an action (H × K )×G → G, where ((h, k), g) 7→ hgk−1, h ∈ H , k ∈ K , g ∈ G. Let G/ (H × K ) denote the categorical quotient SpecO(G)H×K . We determine when this quotient is smo...

In this paper, the exergoeconomic analysis was conducted to an existing ultra-supercritical coal-fired power plant in China to understand the cost-formation process, to evaluate the economic performance of each component and to find possible solutions for more cost-effective designs. The total revenue requirement (TRR) and the specific exergy costing (SPECO) methods were applied for economic an...

This study is part 2 of the investigation on exergetic and exergoeconomic parameters an existing system with air-to-water heat pump unit as a source. Part 1 presents used experimental setup. The main aim conducted tests to develop models produced rate energetic COP at different ambient conditions. obtained data in where exergetinc assessment carried out. analysis was performed dynamically chang...

The painting with St. Thomas Becket, Stephen and Nicholas of Bari that decorates one the lunettes in so-called lower church at Sacro Speco Subiaco is an enigma from art-historical point view, for two reasons. First, on iconographical level, lunette interrupts flow story Benedict’s life unfolding systematically all walls church. Second, formal fresco clearly presents more archaic features than s...

In the present research, energy in geothermal fluid is utilized to generate power. first case of power generation, model double-effect instantaneous evaporation cycle employed, and second one, single-effect combined Rankine with different organic fluids are utilized. The effect several examined. SPECO method has also been applied economic analysis. Given analysis, net generation highest for wat...
