摘要：2016年9月，筹划多年的勒内马格丽特（Rene Magritte）的个展在巴黎蓬皮杜艺术中心开幕了，尽管绘画已经不是当代艺术的主流了，但是这位老画家的魅力还是点燃了人们无限的热情。先给您透露个秘密：马格丽特不是个画家，是个会画画的思想家。

摘要：众所周知，设计功放是一门“黑色艺术”，简单讲就是当设计者在首次完成自己的作品时，根本无法知道这台功放的声音表现如何。有的功放经受住了历史长河的考验，几十年后人们对这台机器的声音还津津乐道；有的机器尽管出自名家之手，面市不久就被人遗忘。声音艺术具有较强的主观特点，因此回顾一下晶体管功放的发展历史，使我们更能透过纷繁杂乱的表面，看到各种各样的电路、元件、工作状态的设定对功放声音的影响。

摘要：In this paper, a low-noise preamplifier for MRI is designed and studied. A noise matching network consisting of three elements is presented. To the single-stage AsGa-FET preamplifier working at 128 MHz, the measured gain through network analyzer (HP8712C) and noise figure through noise figure analyzer (8970B) are 25 and 0.43 dB, respectively.

摘要：This paper studies the consistency of the extended Kalman filter(EKF) for a kind of nonlinear systems. Based on the EKF algorithm, the authors propose the quasi-consistent EKF(QCEKF)as well as the tuning law for its parameters. The quasi-consistency of the proposed algorithm is ***, the feasibility of the algorithm is illustrated by the numerical simulation on an orbit determination example.

摘要：构建过程、声学和光学处理及特别设计此项目是在仅为全球17名顶级人士私人定制的庄园，依山傍水处于青岛黄金地带，自然针对简单、便捷、智能，以满足各种娱乐生活场景。在设计视听室之前，设计公司对环境进行整体的评估和测试。为创造浓厚的360度包围感，设计公司首先对室内环境做混响时间测试，

摘要：Herning艺术中心设计关注场所筑造，强调自然风景与建筑主体相融合。设计将平坦的场地转化成隐蔽于草坡和池塘之中的泊车处和服务区域，从而打造新景致；同时设置激发参观者思考与交流的护堤小径，构建独具文化气质的景观空间。

摘要：This study presents a new method of 4-pipelined high-performance split multiply-accumulator (MAC) architecture, which is capable of supporting multiple precisions developed for media processors. To speed up the design further, a novel partial product compression circuit based on interleaved adders and a modified hybrid partial product reduction tree (PPRT) scheme are proposed. The MAC can perform 1-way 32-bit, 4-way 16-bit signed/unsigned multiply or multiply-accumulate operations and 2-way parallel multiply add (PMADD) operations at a high frequency of 1.25 GHz under worst-case conditions and 1.67 GHz under typical-case conditions, respectively. Compared with the MAC in 32-bit microprocessor without interlocked piped stages (MIPS), the proposed design shows a great advantage in speed. Moreover, an improvement of up to 32% in throughput is achieved. The MAC design has been fabricated with Taiwan Semiconductor Manufacturing Company (TSMC) 90-nm CMOS standard cell technology and has passed a functional test.

摘要：提到羽商的“艺术家”放大器,似乎其设计师的名声还要远远盖过品牌的知名度,虽然笔者至今无缘与之谋面,不过从他设计推出作品所蕴藏的艺术价值来推断,于建兵先生对于美的含义,必然是有着比常人具有更深层次的理解与认知。在我看来,懂得运用将技术与艺术巧妙地融合在一起的设计者,常常能直接体现出他(她)们的审美情趣、文化修养、亦或生活态度。我们拒绝“拿来主义”,也讨厌“快餐文化”,是因为我们知道音响与音乐一样,也是情感的寄托,个性的凸现,而绝非硬性的抄袭与模仿。

摘要：Vivid Audio在我的印象当中是一个挺另类的Hi-End品牌。我之所以说它另类,估计大家看到今天评论的GIYA G1的外形设计之后也会跟我有相同的想法。全流线型的箱体,头顶长长的,而且圆弧线形的顶部设计酷似魔人布欧1日本著名动漫《龙珠》的卡通人物）的形象,还有人说它像一只辣椒等等,总之不同人看到它都有不同的感觉。只要跟其他音箱摆在一起的时候,GIYA G1就显得非常的与众不同。

摘要：Efficient coupling from the silicon waveguide to the GeSi layer is the key to success in the GeSi electro-absorption （EA） modulator based on evanescent coupling. A lateral taper in the upper GeSi layer has room for increasing the modulating efficiency and alleviating the sensitivity of the extinction ratio （ER） and insertion loss （IL） to the length of the active region. The light behavior and the effect of the taper are explored in detail using the beam propagation method （BPM）. After optimization, the light can nearly be totally confined in the GeSi layer without any oscillation. The modulator with the designed taper can achieve low IL and high ER.
