ARC International plc was a developer of configurable microprocessor technology and is now owned by Synopsys. ARC developed synthesisable IP and licensed it to semiconductor companies. The configurability of the ARC happens at design time using the ARChitect processor configurator. The core was created in such a way that it is extensible. Unlike most embedded microprocessors you can add extra instructions, registers and functionality as if they were made from Lego. Wikipedia.

Herein, we have demonstrated a highly efficient, flexible, and low-cost (Pt-free and TCO-free) counter electrode made of a highly conductive poly(3,4-ethylene dioxythiophene) (PEDOT)/exfoliated graphite (EFG) composite in solid state dye-sensitized solar cells (DSSCs) employing polymer electrolytes. Electropolymerized one-dimensional PEDOT nanofibers were firmly attached to a flexible EFG sheet affording high catalytic activity and electron conductivity. PEDOT/EFG counter electrode-based DSSCs showed an energy conversion efficiency of 5.7% with a solid polymer electrolyte, which is significantly higher than conventional Pt electrodes (4.4%) under similar device architecture conditions. © The Royal Society of Chemistry 2013.

Many connection elements are modeled as rectangular members under various combinations of shear, flexural, torsional and axial loads. Strength design is now used for steel members and connections; therefore, the traditional method of combining loads using beam theory needs to be updated to comply with strength design philosophy. Due to the extensive research available on the plastic interaction of rectangular members, a review of existing equations forms the basis of this paper. In cases where existing research is unavailable, new derivations are provided. An interaction equation is developed for strength design of rectangular connection elements under any possible loading combination. Source

Gusset plates are used in steel buildings and bridges to connect diagonal members to other members in the structural system. In design, gusset plates are currently modeled as rectangular columns with an effective cross-section defined by a 30° stress trajectory. The buckling strength is calculated using a standard column curve with empirical effective length factors. Previous tests showed that local yielding allowed the stresses to redistribute and create a wider stress trajectory. Because slender gusset plates cannot redistribute stresses without buckling, a variable stress trajectory has been established, which is dependent on the lateral buckling slenderness parameter. This paper describes an improved method to calculate the buckling strength of gusset plates using variable stress trajectory angles. The effective length factors used in design were also evaluated, and revised values were proposed. The design model is valid for single- and double-plane corner gusset plates in steel buildings and bridges, including extended corner gusset plates commonly used for seismic design. Compared to the results of 159 specimens from 15 previously-published research projects, the design model is reasonably accurate. © 2014 American Society of Civil Engineers. Source

The present invention relates to a process for the wet production of granules from powdered materials, in particular raw materials for the production of glass. The process of the invention comprises the following successive steps: (i) the powdered materials to be granulated are divided into at least two portions: a first portion and a second portion; (ii) a binder liquid is added to the first portion of powdered materials; (iii) the first mixture thus obtained is agglomerated in the granulator in order to obtain granules (a); (iv) the second portion of powdered materials is added to the granulator; and (v) the new mixture obtained is agglomerated in the granulator in order to obtain granules (b). This sequenced granulation process allows granules to be obtained that have a degree of moisture that assures their stability and their ease of handling eliminating the drying step.
