Optimization of Vertical Formwork Layout Plans Using Mixed Integer Linear Programming [PDF]

open access: yesInternational Journal of Civil Engineering, 2016
A formwork is a structure used to contain poured concrete and to mold it to the required dimensions. Different formwork systems provide a wide range of concrete construction solutions that can be chosen to suit the needs of a particular structure. The selection of panels and the design of the formwork layout for concrete structures, especially if the ...

Vertex-Unfoldings of Simplicial Polyhedra [PDF]

open access: yes, 2001
We present two algorithms for unfolding the surface of any polyhedron, all of whose faces are triangles, to a nonoverlapping, connected planar layout. The surface is cut only along polyhedron edges. The layout is connected, but it may have a disconnected

The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Key Concepts of Structural Mechanics Design for a New Type of Vertical Silo Arranged in Rows and Columns

open access: yesLiang you shipin ke-ji, 2022
Vertical silos have become the first choice for large silos to store grain due to their large capacity and small footprint. However, the problem of grain accumulation and small volume in star silos has not been well resolved.

Achieving High ON State Current through Ferroelectric Polarization‐Dependent Interfacial Resistance Switching in Undoped Orthorhombic HfO2 Films

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectric tunnel junction devices based on epitaxial undoped ferroelectric HfO2 films demonstrate stable switching endurance of over 106 switching cycles, low write voltages of ±3 V, 16 measured resistance states, and neuromorphic capability.

On the Area of Hypercube Layouts [PDF]

open access: yes, 2001
This paper precisely analyzes the wire density and required area in standard layout styles for the hypercube. The most natural, regular layout of a hypercube of N^2 nodes in the plane, in a N x N grid arrangement, uses floor(2N/3)+1 horizontal wiring ...

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

open access: yesAdvanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

DYNAMIC YARD TEMPLATE DESIGN TO IMPROVE UTILIZATION AND OPERATION EFFICIENCY ON VERTICAL LAYOUT-CONTAINER YARDS CONSIDERING UNCERTAINTY OF TRUCK ARRIVAL

open access: yesJournal of Engineering and Management in Industrial System, 2018
Loading containers into a vessel can be delayed because of inefficient processes in the container yard. These container yard inefficient processes can be caused by inappropriate stacking position and inefficient crane operation.
