A Scalable and Adaptive Technique for Compensating Process Variations and Controlling Leakage and Delay in the FPGA

Yusuf Leblebici, Christian Piguet, Bahman Kheradmand Boroujeni

A new circuit style is proposed to tune the delay, subthreshold leakage (ISUB), and gate leakage (IG) of high fan-in multiplexer circuits, such as the FPGA Look-Up Table (LUT) and Switch-Box (SB), without increasing the Gate Induced Drain Leakage (GIDL) cu ...

Heat Transfer and Performance Characteristics of Axial Cooling Fans with Downstream Guide Vanes

Peter Ott, Alexandros Terzis

This study examines experimentally the effect of stators on the performance and heat transfer characteristics of small axial cooling fans. A single fan impeller, followed by nine stator blades in the case of a complete stage, was used for all the experimen ...

Effects of Swirl Velocities From Fan Assemblies Mounted on Lifting Surfaces

Alexandros Terzis, Charilaos Kazakos, Nikolaos Papadopoulos

The penetration of a jet of fluid into a traversal moving stream is a basic configuration of a wide range of engineering applications, such as film cooling and V/STOL aircrafts. This investigation examines experimentally the effect of blowing ratio of fans ...

Effect of Stators on the Performance and the Thermal Capabilities of Small Axial Cooling Fans

Peter Ott, Alexandros Terzis

This investigation examines experimentally the effect of stators on the performance curves and the heat transfer capabilities of small axial cooling fans. The experimental data indicated that the results are highly affected by the flow conditions at the fa ...

Computing Gröbner fans

This paper presents algorithms for computing the Gröbner fan of an arbitrary polynomial ideal. The computation involves enumeration of all reduced Gröbner bases of the ideal. Our algorithms are based on a uniform definition of the Gröbner fan that applies ...

Influence of mechanical mistuning on the forced response of a turbine cascade

Arrigo Beretta

An experimental investigation has been conducted in the non-rotating annular test facility of the "Laboratoire de Thermique Appliquée et de Turbomachines" (LTT), "École Polytechnique Fédérale de Lausanne" (EPFL). The influence of frequency mistuning and mo ...

Comparison of transmission and the 90-degree holographic recording geometry

Demetri Psaltis

We compare the system performances of two holographic recording geometries using iron-doped lithium niobate: the 90-degree and transmission geometry. We find that transmission geometry is better because the attainable dynamic range (M/#) is much higher. Th ...
