A fully capillary-driven μDMFC twin-stack operating in all orientations
2015 Edition, June 1, 2015 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel concept of fully automatic fuel supply for passive micro direct methanol fuel cells (μDMFCs) twin-stack is presented. A special capillary pump featured by symmetric channel array is designed to transport methanol fuel spontaneously by...

Design of a Passive and Portable DMFC Operating in All Orientations
2009 Edition, January 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A microfluidic layout concept for passive and portable Direct Methanol fuel Cells (DMFCs) is presented. We proofed this concept by developing a DMFC that continuously runs for 40 hours in all orientations without the need for any active components such as pumps or...

Finding all stable orientations of assemblies with friction
1996 Edition, Volume 12, April 1, 1996 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we include Coulomb friction at contacts between bodies and give a characterization of the entire set of stable orientations of an assembly under uniform gravity. Our characterization is based on the concept of potential stability, which describes a...

Finding all gravitationally stable orientations of assemblies
1994 Edition, January 1, 1994 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Previous work by Mattikalli et al. (1993) considered the stability of assemblies of frictionless contacting bodies with uniform gravity. A linear programming-based technique was described that would automatically determine a single stable orientation for an assembly (if such an...

All-epitaxial orientation-patterned GaAs for nonlinear optical frequency conversion
2000 Edition, Volume 1, January 1, 2000 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We have demonstrated all-epitaxial growth of orientation patterned GaAs films having suitable aperture and domain period for bulk-focused frequency conversion from the near-IR to mid-IR. The films have good optical properties and enable quasi-phasematched frequency conversion with...

A Coordinate System Establishing Method for All Around Space Orientation
2013 Edition, September 1, 2013 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A new coordinate system establishing method specific to all around space orientation are proposed in this paper. The error corresponding to the peak value of the error probability density of proposed arithmetic is much smaller than the traditional arithmetic even non...

Upscaling PV Power Considering Module Orientations
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Only a small share of photovoltaic (PV) systems installed in Germany are equipped with near real-time measurement devices. To estimate the generated power of a large number of unmeasured photovoltaic systems (e.g., to determine the sum of all systems in a...

Band Variations Caused by Strain Effects for Quantum Wires With Arbitrary Orientations
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We develop a 2-D continuum elasticity model to study semiconductor band variations caused by strain effects for quantum wires (QWRs) with arbitrary orientations on the (001) plane. The model is implemented by the finite-element method, considering the anisotropic properties of...

Comparison of (001), (110) and (111) uniaxial- and biaxial- strained-Ge and strained-Si PMOS DGFETs for all channel orientations: Mobility enhancement, drive current, delay and off-state leakage
2008 Edition, December 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Using the non-local empirical pseudopotential method (bandstructure), full-band Monte-Carlo simulations (transport), self-consistent Poisson-Schrodinger (electrostatics) and detailed band-to-band-tunneling (BTBT) (including bandstructure and quantum effects) simulations, the effect of...

Band Variations Caused by Strain Effects for Quantum Wires With Arbitrary Orientations
2020 Edition, Volume 67, January 1, 2020 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We develop a 2-D continuum elasticity model to study semiconductor band variations caused by strain effects for quantum wires (QWRs) with arbitrary orientations on the (001) plane. The model is implemented by the finite-element method, considering the anisotropic properties of...
