营造和谐空间——浅析环境景观中公共设施的无障碍设计

环境景观中公共设施无障碍设计的目的是为了充分满足老年人、儿童以及残疾人群体在使用环境景观中公共设施的需求。在环境景观中合理设置无障碍的公共设施,是现代城市兼顾实用功能与审美功能的人性化体现。文章从环境景观中公共设施无障碍设计的现状来分析公共设施无障碍设计的思考方向。     

留白之美——版式设计中空白的运用

所谓版式设计是指在有限的版面空间里,将版面的构成要素——点、线、面,根据特定内容的需要进行组合排列,并运用造型要素以及形式原理,把构思与计划以视觉形式表达出来,寻求艺术手段来正确地表现版面的信息。在版式设计中一般设计师都会把重点放在黑的设计上,却容易忽视白的设计。文章以版式设计教学为例,阐述版式设计中白的作用及其地位,并探讨版式设计中如何恰当使用空白。     

构成主义实践对现代视觉传达设计的影响

现代视觉传达设计已经成为我们生活的重要组成部分。以视觉为中心的视觉文化符号传播系统正向传统的语言文化符号传播系统提出挑战。俄国构成主义以及莫霍利·纳吉等在构成主义实践中对理性的思考、形式的挖掘、画面信息的强调和视觉经验的突破,深刻影响着现代视觉传达设计,并为其确立了操作的规范。     

设计素描观察能力的培养

观察能力的培养是设计素描训练的基本任务之一。设计素描应以传统素描的观察方法为基础,并更加强调用理性的、逻辑的、创造性的思维方法来观察、认识、分析物象。设计素描的观察方法必须经过由感性到理性的循序渐进的过程。文章通过:1、整体对比的观察。2、宏观与微观的观察。3、不同视点与角度的观察,三个依次渐进的过程来分析设计素描的观察方法。通过分析,希望在设计素描教学中把观察能力的培养提升到一个相当重要的位置。只有这样才能为日后设计专业学习打下良好的设计创意思维基础。     

浅析现代室内设计中的自然风尚

人们一直都在为自己营造着一个与大自然隔离的空间,文章针对这种回归自然的室内设计理念,提出现代室内设计中需要自然风尚的观点。从自然风尚的影响和理念形成入手,在物质和精神两个层面探讨了室内设计中,运用自然的空间装饰与光线处理、纳入与自然和谐的色彩元素、应用天然材料、创造性地利用废旧材料等装饰设计方法,可以带给人愉悦的心情和优雅、纯粹、自然与不凡的感受。

高校信息化平台遗留系统的重用设计与实现

目前,随着国家推进国民教育资源的优化组合,许多高校进行扩建和合并,增设了院系,新建或接收了新校区,信息系统规模不断扩大。新增院系和校区的信息系统与主校区的信息系统无法有效融合,大量需要共享的关键信息被封闭在相对独立的系统里。如何对现有遗留系统进行统一规划,封装成可重用的Web服务组件,从而集成各个孤立的信息系统,消除信息孤岛现象,实现遗留系统的重用设计,是高校信息一体化平台建设中的亟待解决的问题。     

Signal transformation and interpolation based on modified DCT synthesis

This paper proposes a novel signal transformation and interpolation approach based on the modification of DCT (Discrete Cosine Transform). The proposed algorithm can be applied to any periodic or quasi periodic waveform for time scale and/or pitch modification purposes in addition to signal reconstruction, compression, coding and packet lost concealment. The proposed algorithm has two advantages:

• (i) 

  Since DCT does not have the explicit phase information, one does not need the cubic spline interpolation of the phase component of the sinusoidal model.

• (ii) 

  The parameters to be interpolated can be reduced because of the energy packing efficiency of the DCT. This is particularly important if signal synthesis is carried out on a remote location from the transmitted parameters.

The results are presented on periodic waveforms and on speech signal in order to appreciate the fidelity of the proposed algorithm. In addition, the proposed method is compared with TD-PSOLA, sinusoidal model and phase vocoder algorithms. The results are presented in objective PESQ scores for time scale modification and output files are provided as supplementary material,¹ for subjective evaluation, for packet lost concealment. Results prove that the proposed modification of the DCT synthesis provides a favorable algorithm for specialists working in the signal processing area.     

A Copula based observation network design approach

In this paper, a method for environmental observation network design using the framework of spatial modeling with copulas is proposed. The methodology is developed to enlarge or redesign an existing monitoring network by taking the configuration which would increase the expected gain defined in a utility function. The utility function takes the estimation uncertainty, critical threshold value and gain-loss of a certain decision into account. In this approach, the studied spatial variable is considered as a random field in where variations in time is neglected and the variable of interest is static in nature. The uniqueness of this approach lies in the fact that the uncertainty estimation at the unsampled location is based on the full conditional distribution calculated as conditional copula in this study. Unlike the traditional Kriging variance which is a function of mere measurements density and spatial configuration of data points, the conditional copula account for the influence from data values. This is important specially if we are interested in purpose oriented network design (pond) as for example the detection of noncompliance with water quality standards, the detection of higher quantiles in the marginal probability distributions at ungauged locations, the presence or absence of a geophysical variable as soil contaminants, hydrocarbons, golds and so on. An application of the methodology to the groundwater quality parameters in the South-West region of Germany shows its potential.     

Model‐based code generation for HLA federates

This paper addresses the problem of automated code generation for a High Level Architecture compliant federate application given its behavior model. The behavior model is a part of the architectural model of a federation that the federate can participate in. The federate behavior model is based on Live Sequence Charts, adopted as the behavioral specification formalism in the Federation Architecture Metamodel (FAMM). FAMM serves as a formal language for describing federation architectures. An objective is to help the testing of federation architecture by means of its prototype implementation early in the development lifecycle. A further objective is to help developers construct complete federate applications that are well modularized. The approach to achieve these objectives is aspect‐oriented in that the generated code, which handles the federate's interactions with a federation execution, serves as the base code, where the computation logic is to be weaved as an aspect.
