Type-selection design system for hydraulic support

open access: yesGong-kuang zidonghua, 2017
In order to facilitate hydraulic support type-selection design for coal mine designers, a type-selection design system for hydraulic support based on B/S model was developed by use of C# language, ASP.NET technology, Visual Studio 2013 system development

Molecular design of the phenol type extractants [PDF]

open access: yesSpringerPlus, 2013
A method of optimisation of new extractants structure using the desirable function has been developed. Earlier the desirable function has been proposed by Harrington (Ind Qual Control 21: 494-498, 1965) for the optimisation of processes with several response functions.

Informing the Design of an Accessible Arabic Typeface: A Visual Analysis to Identify Letterform Features of Dyslexia-Friendly Typefaces

open access: yesSocieties
Dyslexia-friendly typefaces for the Latin script have been proliferating during the past decade. The typefaces are designed to tackle the challenges faced in a dyslexic reading experience by manipulating their letter forms and typographic attributes ...

Fire design of arch-type timber roof

open access: yesИнженерно-строительный журнал, 2016
Lattice timber structures, which are made of elements connected by punched steel plates, are widely used for residential and industrial buildings. The main types of the structures are trusses, frames, and arches, which enables covering spans up to 30 m ...

Ultrasonic wave propagation in cylindrical vessels and implications for ultrasonic reactor design [PDF]

open access: yes, 2010
Reactors in which processes are enhanced by ultrasound are hampered by the lack of a theoretical framework on their design. Simulation results of ultrasonic wave propagation in a cylindrical geometry are presented in this work, which are then used to ...

螺旋推进式油茶籽壳低损清选机设计及试验Design and test of spiral-propelled type Camellia oleifera seed shell low-loss sorting machine

open access: yesZhongguo youzhi
针对现有齿光辊式油茶籽壳清选机存在“磕籽”现象,造成油茶籽损失率较高的问题,利用油茶青果脱壳后的籽、壳物理特性的差异,设计了螺旋推进式油茶籽壳低损清选机,对该清选机螺旋辊直径与长度、螺旋辊转速、螺纹形式、螺距和螺旋升角等关键参数进行设计,建立油茶籽受力模型。以清选率和油茶籽损失率为评价指标,采用单因素试验和响应面试验对清洗机工作参数喂入量、螺旋辊转速和对辊间隙进行优化。结果表明:设计的螺旋推进式油茶籽壳低损清选机螺旋辊的直径为50 mm,长度为1 000 mm,转速不超过 200 r/min,螺距为50

Type synthesis to design variable camber mechanisms

open access: yesAdvances in Mechanical Engineering, 2016
This article proposes multiple hinges’ type spectrum that provides an effective description of the multiple hinges of planar kinematic chains. The relationships between characteristic invariants are established and applied into type synthesis methods.

Cell type-specific delivery by modular envelope design

open access: yesNature Communications, 2023
The delivery of genetic cargo remains one of the largest obstacles to the successful translation of experimental therapies, in large part due to the absence of targetable delivery vectors.

On the types of information and mechanism design

open access: yesJournal of Computational and Applied Mathematics, 1988
By mechanism design the communication structures used to extract and communicate information about the current state of environment is meant. The author concentrates on those mechanisms where the status of environment is determined by a team. He models the problem of whether a stated objective is satisfied by a mechanism as a performance function.

Type Classes for Lightweight Substructural Types

open access: yes, 2015
Linear and substructural types are powerful tools, but adding them to standard functional programming languages often means introducing extra annotations and typing machinery.
