We present a method for contactless manipulation of multiple small objects in a plane using multiple air jets. When the objects are initially clustered as a group, the group's center of gravity is used as a representative point and the entire group ...

Dual-Polarized Wideband Filtering Antenna Array Based on Stacked-PCB Structure
This paper investigates a thin low-pass filtering antenna array based on dual-polarized Vivaldi elements. The low-pass filtering in the antenna elements reduces the requirement for the front-end filtering between the antenna and the microwave electronics,

Design and Synthesis of Planar Chiral Bisphosphine Ligands Based on Diphenyl [2.2]-Paracyclophane
Planar chiral bisphosphine ligands based on diphenyl [2.2]paracyclophane (PhPhanePHOS) were successfully synthesized in a practical manner in four steps from commercially available 4,12-bisbromo-[2.2]paracyclophane as a new family of bisphosphine ligands.

Non-Isothermal Modeling of Planar Solid Oxide Fuel Cell [PDF]
A Solid Oxide Fuel Cell (SOFC) with internal reformation and a parallel flow configuration is modeled. The solution domain of the model is divided into four sections: the fuel channel, air channel, bipolar plates, and the cell core (PEN), which comprises

Split Euler Tours In 4-Regular Planar Graphs
The construction of a homing tour is known to be NP-complete. On the other hand, the Euler formula puts su cient restrictions on plane graphs that one should be able to assert the existence of such tours in some cases; in particular we focus on split ...
