Quasi-Static Voltage Scaling for Energy Minimization with Time Constraints
No full textSupply voltage scaling and adaptive body-biasing are important tech-niques that help to reduce the energy dissipation of embedded systems. This is achieved by dynamically adjusting the voltage and performance settings according to the application needs. In order to take full ad-vantage of slack that arises from variations in the execution time, it is important to recalculate the voltage (performance) settings during run-time, i.e., online. However, voltage scaling (VS) is computationally ex-pensive, and thus significantly hampers the possible energy savings. To overcome the online complexity, we propose a quasi-static voltage scal-ing scheme, with a constant online time complexity O(1). This allows to increase the exploitable slack as well as to avoid the energy dissipated due to online recalculation of the voltage settings. We conduct several experiments that demonstrate the advantages of the proposed technique over the previously published voltage scaling approaches

Bilipschitz maps of boundaries of certain negatively curved homogeneous spaces
No full textIn this paper we study certain groups of bilipschitz maps of the boundary minus a point of a negatively curved space of the form R x M R-n, where M is a matrix whose eigenvalues all lie outside of the unit circle. The case where M is diagonal was previously studied by Dymarz (Geom Funct Anal (GAFA) 19:1650-1687, 2009). As an application, combined with work of Eskin-Fisher-Whyte and Peng, we provide the last steps in the proof of quasi-isometric rigidity for a class of lattices in solvable Lie groups.X1178sciescopu
KAIDAH MORFOFONEMIK PREFIKS PENG- DALAM BAHASA INDONESIA
No full textThis study aims to reveal the morphophonemic rules of peng prefixes in Indonesian. This research is a type of qualitative research using a morphophonemic approach. The data in this study are words that use the prefix {peng-} obtained from digital track records. The method used is the listening method followed by observation and note-taking techniques. In the data analysis, the distribution method was used with the Direct Element Sharing technique. The results showed that there were three morphophonemic processes: (1) phoneme changes occurred in the prefix {peng-} which was nasalized to /pem-/, /peny-/, /pen-/, and /peng-/; (2) the addition of phonemes occurs in the affix {peng-} which is nasalized to become /penge-/; and (3) the omission of phonemes occurs in the prefix {peng-} to /pe/, and basic morphemes with initial phonemes /k/, /t/, /s/, /p/.

Novel stability criteria for T-S fuzzy systems

The so-called nonquadratic membership-dependent Lyapunov function is first proposed, which is formulated in a higher order form of both the system states and the normalized membership functions than existing techniques in the literature. Then, new membership-dependent stability conditions are developed by the new Lyapunov function approach. It is shown that the conservativeness of the obtained criteria can be further reduced as the degree of the Lyapunov function increases. Two numerical examples are given to demonstrate the effectiveness and less conservativeness of the obtained theoretical results.Xudong Zhao, Lixian Zhang, Peng Shi, and Hamid Reza Karim
