标准的存在形式与类型谱系

本文从全域的角度考虑标准的概念,研究构建了包括主客观关系的全域标准概念,将标准的存在形式分为自然界形成的客观标准、人类构建的主观标准和主观对客观认识的标准三大类,建立了主客观标准存在形式的分类谱系,分析了客观形成的标准、主观建立的标准和主观对客观认识的标准的形式、类型和特点等,提出和论证了人类思维进化的重要环节——幻想,深入讨论了标准的哲理关系。     

标准的起源和发展的形式(上)

本文对人类历史上标准的起源和标准产生形式进行了深入的讨论,建立了人类历史上具有里程碑意义的标准形成关系。这些重要的标准形式为动作行为标准、语言标准、工具标准、文字标准、度量衡标准、文件标准等。本文深入讨论了每类标准产生的背景原因、形成的形式、特点、作用等。论证得出标准的起源形式不是以往所说的语言形式的标准,而是动作行为形式的标准,研究将标准的起源结论提前了两个历史阶段。本文还分析了标准发展的综合关系。     

绿色设计理念的地域性室内设计方法

＂地域性室内设计方法＂是＂绿色设计＂在文化形态方面的表现,属于绿色设计表现形式的一种。绿色室内设计包括物质和精神两个层面的内容,决定室内空间变化和差异的元素有很多,我们主要从空间形态、装饰材料这两个室内设计元素来分析结合绿色设计理念的地域性室内设计,对二者的结合进行思考,寻找结合点进行分析。     

Morphological facilitation following prefixed but not suffixed primes: Lexical architecture or modality-specific processes?

Morphological facilitation was examined in immediate (Experiment 1) and long-term (Experiment 2) lexical decision with English materials. For the target (payment), related primes consisted of base-alone (pay), affix-plus-base (prepay), or base-plus-affix (payable) combinations, thereby defining position of overlap. In addition, modality of presentation varied for primes and targets (Experiment 1). At short lags, the advantage for prepay-payment over payable-payment type pairs was significant when primes were visual (V) and targets were auditory (A), marginal under AV conditions, and nonexistent under VV conditions. At long lags, the magnitude of VV did not vary with position of overlap. Morphological facilitation was stable across changes in modality following prefixed and simple forms, reflecting lexical architecture. By contrast, the absence of facilitation following suffixed primes presented cross-modally implicates modality-specific processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

基于涡旋电磁波的大容量通信系统设计

鉴于涡旋电磁波所体现出的独特空间电磁场分布特征,以及其携带的轨道角动量在理论上所具有的无穷维度模态正交特性,涡旋电磁波在无线通信领域和雷达探测与成像领域均表现出重要的研究价值和应用潜力;通过涡旋电磁波空间电磁场的分布和原理入手,采用在C波段设计阵元交替排布的双圆环均分天线阵列,并基于带状线屏蔽性能强的优势设计4路1分8的叠层馈电网络,从而产生4种混合模态(+1,-1,+2,-2)的涡旋天馈系统;通过搭建混合模态涡旋电磁波大容量通信系统测试收发天馈之间模态隔离度大于15dB,在此基础上加入软件无线电平台验证通信系统多路涡旋波信号传输特性,测试验证4个端口均可正确接收、解调电磁信号,实现频谱效率4倍的提升。     

Associations with home hemodialysis modality failure and mortality

Background: Limited data exist on risk factors for home hemodialysis (HH) failure and mortality. We sought to determine whether age, helper status, or ethnicity was associated with home dialysis failure or mortality. Methods: We conducted a retrospective cohort study of all prevalent and incident patients from a regional dialysis unit who initiated HH training from December 2000 to September 2002. Baseline demographics, program entry and exit dates, and mortality were ascertained. Characteristics of those more likely to remain in the program were assessed using logistic regression; survival was determined using Cox proportional hazards models. Results: Of the 1117 patients enrolled for dialysis, 116 patients were trained in the HH program (6.8%). Of those, 45.7% remained in the program, 10.3% received a transplant, 10.3% returned to in‐center dialysis, 1.7% were lost to follow‐up, and 31.7% expired. Compared to patients who returned to center or received a transplant, patients who remained on HH were more likely to be older, to have been on dialysis longer, and to have diabetes as their primary renal disease. Ethnicity, sex, or type of helper did not affect home program status. Among those who remained in the HH program, those with hypertension or other renal diseases had better survival than those with diabetes, as did those who had related helpers compared to those with unrelated helpers. Conclusions: Older and younger ages, but not ethnicity, helper status, or sex, were associated with home dialysis failure. Diabetes remained an independent risk factor for increased mortality. HH remains a viable option for many patients.     

基于ANSYS的汽车仪表板横梁焊接支架模态分析

采用有限元分析软件ANSYS对汽车仪表板横梁焊接支架进行模态分析,得到支架的前6阶固有频率和振型。结果表明,横梁支架低阶固有频率远离汽车发动机的怠速激振频率,不会出现整体共振现象;横梁支架结构优化时,要重点考虑驾驶舱面板左右安装支架、中部左右连接支架以及离合器踏板支架等构件。

基于非文本模态强化和门控融合方法的多模态情感分析

针对各模态之间信息密度存在差距和融合过程中可能会丢失部分情感信息等问题,提出一种基于非文本模态强化和门控融合方法的多模态情感分析模型。该模型通过设计一个音频-视觉强化模块来实现音频和视觉模态的信息增强,从而减小与文本模态的信息差距。之后,通过跨模态注意力和门控融合方法,使得模型充分学习到多模态情感信息和原始情感信息,从而增强模型的表达能力。在对齐和非对齐的CMU-MOSEI数据集上的实验结果表明,所提模型是有效的,相比现有的一些模型取得了更好的性能。
