NI founders Truchard and Kodosky: The human ties that bind

[EE Times is celebrating its 40th anniversary, with special articles to honor the innovators who made the electronics industry what it is today, as well as the visionaries who are taking it forward. Look for more stories on the 40th anniversary in our special section.]

It takes a certain something to be an engineer. It takes a certain something else to come up with an idea that becomes a thriving electronics company, one that's grown for nearly 40 years. Then it takes something to stay with the company you founded, continue to drive its growth and innovation AND give back to your community relentlessly.

And it takes some that borders on the incomprehensible for the co-founders of a single company to share all of that at once.

Meet Jeff Kodosky and Jim Truchard, founders of National Instruments (Austin, Texas).

EE Times 40th: Ten visionaries to watch

[EE Times is celebrating its 40th anniversary, with special articles to celebrate the innovators who made the electronics industry what it is today, as well as the visionaries who are taking it forward.]

Predicting the future is always fraught with peril, but the visionaries featured here are boldly going where no one has gone before.

To be sure, the personalities featured in this slideshow are not unique--in each category dozens of other pioneers could have been used in lieu of those chosen. Nevertheless, the pioneering vision and unflinching dedication of those featured in this slideshow serve as a shining example of how to “do” the future right.

Please forgive us for including two “ringers” who are not human: Wireless@MIT (which features a photo of the futuristic center where two MIT visionaries work) and “Lucy” an animated avatar which exemplifies a futuristic trend.

David Shepler-IBM

David Shepler was the Jeopardy Challenge Program Manager at IBM Research (shown here giving pointers to the human contestants on how to compete against Watson--IBM’s pioneering artificial-intelligence technology). After Watson beat the reigning human champions on Merv Griffin’s NBC television game show “Jeopardy,” hosted by Alex Trebek, Shepler served as Chief of Operations for the Watson research team’s efforts to adapt its AI to the healthcare field. Now patients in the WellPoint network--the nation's largest health benefits provider--can use Watson to help make more accurate and informed medical diagnoses. Next, Watson is tackling financial services, government-mandate management and retailing. More recently, Shepler became program manager for IBM's Smarter Energy Research Institute, which is developing predictive analytics, system optimization and advanced computation models that will help define the smart grid of the future. Shepler lives in his net zero-energy home in New Paltz, New York.

冰种翡翠观音 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

冰种翡翠观音 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

    冰种翡翠很常见，但用来做成极品的冰种翡翠观音的翡翠原料，就很少了。

一、什么是冰种翡翠观音

    所谓的冰种翡翠观音，说起来就是用质地翡翠透明、毫无瑕疵的冰种翡翠雕刻制作而成的。冰种翡翠并不像玻璃种翡翠一样纯净透明的犹如玻璃一般。但做成的冰种翡翠首饰品、或者是冰种翡翠观音挂坠，就要求选用的料子质地必须通透，肉眼观测不到任何杂质存在。有时候也会用到接近于玻璃种的高冰种翡翠来制作观音。

【价格机制】 ￥29800元
【尺　　寸】 高：62.7mm 宽：41mm 厚：6.2mm 
【颜　　色】 飘花
【透 明 度】 三分之二透明

宝贝描述：冰种的质地透明水润，光泽好。雕刻的工艺一流，飘着蓝花的感觉着实不错，很适合佩戴的冰种翡翠飘蓝花观音。

缅甸翡翠A货冰种飘花观音吊坠 20178

    冰种翡翠观音尽管具有很晶莹透明的特性，但是它和玻璃种不一样，玻璃种翡翠通体给人的感觉显得冰冷，而冰种则会显得七分冰冷、三分温润。而冰种翡翠的质地，就和老坑种有很多相似或相近的地方，都是无色或者是少色。但是冰种的特征就显得水头足、透明度好、光泽度强烈的感觉。

    好的一款冰种翡翠，如果雕刻成佛教最受人尊敬的观世音菩萨头像，则要求翡翠必须要能洗尽铅华呈素姿、要清亮如水柔、晶莹如结冰，要让人看起来至少感觉到是冰清玉骨。只有这样才能符合佛教明心见性的本，才能使佩戴者能一扫烦躁、舍去浮华而尽显沉稳。

    有时候我们也会看到用“飘蓝花冰”的翡翠来制成观音，这里的飘蓝花冰是指在冰种翡翠中，含带呈现出花絮状或者是连绵状的蓝颜色。但不管如何，冰种翡翠观音的价格多是在几千元至上万元不等。

【价格机制】 ￥2980元
【尺　　寸】 高：46.2mm 宽：32.1mm 厚：9mm 
【颜　　色】 晴水
【透 明 度】 三分之一透明

宝贝描述：晴水的色泽淡淡的，质地透明，雕刻师对翡翠的雕刻可是下了很大的功夫。

二、冰种翡翠观音的保养

    佩戴观音的时候，并不一定要遵循“男戴观音女戴佛”的话，只要喜欢，皆可以佩戴。

    对于冰种翡翠观音的保养，我们要做到“一防二常三忌讳”。就是要求我们要尽量防止冰种翡翠观音被磨损；二常就是常常检查翡翠观音的吊坠是否已牢固，以此避免在佩戴过程中脱落而摔坏。还要时常对翡翠观音进行擦拭和把玩，通过人养玉、玉养人的方式把翡翠观音供奉好；最后的忌讳就是防止冰种翡翠观音和其它的化学物质接触在一起，如不要沾染上油污、也不要沾染上洗发水、洗面奶等等酸、碱化学物质，这样的话很容易就使冰种翡翠观音失去色泽而变得黯淡，不好看。

紫罗兰翡翠手镯 神秘高贵的象征 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

紫罗兰翡翠手镯 神秘高贵的象征 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

    翡翠的颜色中，以绿色为尊，以紫色为贵。紫罗兰色泽的翡翠，千般多姿态，娇媚留形神。

    紫罗兰翡翠手镯是用颜色含带以紫色为主的翡翠制作成，这是一种早期并不受人们欢迎的色泽，也是一种比较特殊的翡翠品质，行内人喜欢称之为“春”或者是“春带彩”。现今的紫罗兰色的翡翠手镯，是众多人喜爱佩戴和收藏的品质之一。紫罗兰手镯的颜色有三种，分别是淡紫、粉紫、和大紫。但市场上较常见到的只是淡紫和粉紫，如果是满是大紫色的翡翠手镯出现，则是众人哄抢的对象。

【价格机制】 ￥188000元
【尺　　寸】 内径：55.6mm 宽：21.6mm 厚：8.9mm
【颜　　色】 春带彩
【透 明 度】 略微透明

宝贝描述：宝贝的种质细腻透明，典型的春带彩翡翠，水头润滑透亮。以紫罗兰色泽为主，浓艳的绿色为魂，紫罗兰手色泽通体一样，很不错的一款宝贝，值得收藏。你的笑容太美，像一款紫檀香萦绕的紫罗兰手镯一样。

 

缅甸翡翠A货糯冰种春带彩手镯（55.6mm）19508

    紫色在我国一直是一种高贵神秘的色泽，中国的历代帝王和我国本土的道教，都是信奉紫色为上。所以有紫气东来、紫衣绶带的说法，在古代形容女子的时候，也常会说成粉紫的姑娘等等。为此紫色成为了神秘高贵、华丽多姿的象征。为何紫罗兰色泽的翡翠要这样命名呢？因为这样的色泽一干比较淡雅高贵，犹如紫罗兰花一样，即使枯萎都不肯离开枝头的感觉，所以就命名成是紫罗兰翡翠手镯。

紫罗兰翡翠手镯的价格

    常有一些人抨击紫罗兰色泽的翡翠手镯是种水不好的、绿色和紫色搭配在一起会显得太过于妖娆、野魅。所以紫罗兰翡翠手镯的价格只有在几百元到上千元之间而已，以此来误导顾客朋友。实际上这是一种对翡翠无知的体现。紫罗兰翡翠手镯一般不会是单纯的紫色出现，多会是带着绿色和其它的颜色在一起，所以有时候也会叫做的春带彩、三彩翡翠手镯、福禄寿三彩翡翠手镯。一般带有这样色泽的翡翠，其的种质和水头都是达到了很到的地步的，有时候颜色浓艳、质地细腻透明的翡翠手镯，价格还往往不低于绿色的翡翠手镯。

【价格机制】 ￥188000元
【尺　　寸】 内径：53mm 宽：18mm 厚：8.6mm 
【颜　　色】 春带彩
【透 明 度】 略微透明

宝贝描述：紫色和绿色很好过渡结合在一起，色泽明亮浓艳。三生石，三生路，用曼妙的紫绡，陪着你碧玉洞箫，哼起浅吟低唱的小曲、绘下生死不离的契约。

缅甸翡翠A货糯冰种春带彩手镯（53mm）19510

    1、处于中低档的紫罗兰翡翠手镯：其的价格一般只在上千元到万元之间，这类的紫罗兰翡翠手镯是在种质和水头上略显得粗糙些，但也不排除有好的情况存在，属于淡紫色调。

    2、处于中高端的紫罗兰翡翠手镯：不仅要求色泽要浓艳明亮，还要求翡翠的种质和水头、透明度等要达到冰种的程度，最低可以是糯冰种。这类型的翡翠手镯价格一般在几万元到十几万元之间，属于粉紫色调。

    3、高档收藏级别的紫罗兰翡翠手镯：这类型的紫罗兰手镯，不仅仅是色泽明艳，甚至有可能是达到满紫色或者是大紫色的，而且种质、做工、水头和底子、透明度都是达到了上乘的地步。价格在几十万元甚至更高到上千万元。

岫玉的开采方式

岫玉的开采方式

　　根据岫玉的产出类型,岫玉的开采有两种方式:一为掘采,二为捞采.

　　掘采:清代至民国年间采玉方法十分落后,主要以锹、镐、钻、凿等工具,在地面上发现地苗后,须先“扒岇”(即挖去浮土),再掘坑取玉.如遇地下水涌出,则以柳罐斗将水汲干.遇有大块玉则以凿钻孔,装上炸药破碎.因此所得良玉甚少,多被震出纹绺,不堪雕琢.1957年成立玉石矿以后,采玉工艺基本上是沿袭旧式手工作业,露天开采.60年代后,修建了矿山专用公路,架设了专用输电线路,增设了空压机、卷扬机、凿岩机、抽水机等矿山设备.70年代,逐渐转入井下开采,基本实现采掘、运输机械化.80年代后,又引进灌入式、涨药法等开采新工艺、新技术,使玉石的利用率比爆炸法提高20% .

　　捞采:细玉沟玉长久被人们称为“无根之玉”,因此细玉沟向无采场,人们习惯沿河采玉,并称作“采河磨”,采出来外包石皮、内藏美玉的玉称为“河磨玉”.长期以来当地农民在水中采玉的同时还不时在河两边的谷地、砂砾及山表层获得外包石皮、但已呈风化不及河磨玉外表那样光滑的“石包玉”,这种开采方式叫做捞采.

中国玉雕流派之南阳玉雕

中国玉雕流派之南阳玉雕

　　经过玉雕艺人和科技工作者挖掘、整理传统技艺,吸取外地经验,南阳玉雕的工艺不断改进,逐渐形成了自己的独特艺术风格,以技巧的灵活及色泽显贵著称于世.南阳拓宝玉器有限公司董事长、总经理、高级工艺美术师吴元全介绍说,由于独玉色彩丰富,浓淡兼备,一块石料上面往往各色杂陈.

　　这就要求雕刻者要全盘考虑,既要有精彩的布局构思,又要巧用各种颜色,使得整个作品妙趣天成,让欣赏者禁不住拍案叫绝.南阳玉雕制作的《卧龙出山》,利用独玉色彩丰富、鲜素一体的特点,严谨布局,巧用俏色,雕刻精细,气势雄伟,它重3.8吨,长2.5米,高1.6米,是我国目前最大的巨型玉雕,是不可多得的艺术瑰宝.

　　用精选的独山玉制作的五环炉、花薰,吸收了古代青铜器和其它工艺品的特色,创造了多层转球花薰黄,造型古朴端庄,技艺巧夺天工,在法国举办的国际工艺品展览会上,赢得了广泛的好评.南阳人在玉雕加工上,选用原料非常丰富,除独玉外还有来自辽宁岫玉、缅甸翠玉、阿富汗白玉、加拿大碧玉、俄罗斯白玉以及珊瑚、玛瑙、芙蓉石、水晶石、紫晶石、红蓝宝石等150多个玉种.

　　的确,历经千年兴盛而不衰的玉雕产业,形成了浓郁的、博大精深的南阳玉文化,孕育了一代又一代、代代相传、层出不穷、技艺高超的南阳玉雕艺人.南阳的玉雕艺术大师们在继承传统工艺的同时,不断引进、吸收、创新艺术设计雕刻手法.正是悠久的历史、深厚的文化底蕴和得天独厚的美玉资源相结合,才使得南阳玉雕这一艺术瑰宝得以代代相传,发扬光大,惊世之作也不断问世.

　　南阳玉雕艺术大师们设计雕刻的“卧龙出山”、“九龙转动花薰”、“鹿鹤同春”、“万里长城”、“九龙晷”等40余件精品先后获得国家级、省级奖项,多件产品被作为稀世珍宝由故宫博物院、美术馆和收藏家收藏.《九龙晷》礼品长199cm、宽110cm、高80cm、重500kg,该礼品设计风格新颖独特,巧妙构思,匠心独运,把南阳独山玉特有的各种色彩巧妙利用,采用浮雕、透雕、镂空、线刻等多种雕刻手法,使这件产品线条流畅,形神具备,气势雄伟.九条盘龙环绕日晷,表明九州华夏儿女紧密团结,和睦相处,同时表达了九九归一之意.整幅作品寓意民族团结、国家昌盛、祖国统一,表达了河南九千万人民喜迎澳门回归之深情.

　　被誉为“国之瑰宝”、重3500公斤的玉器“渎山大玉海”,是元代忽必烈犒赏三军时盛酒的器物,是中国历史上出现最早最大的巨型玉雕,为中国划时代的艺术珍品,也是世界宝玉石发展史上罕见的杰作.但问世700多年来,其玉料一直众说纷纭,未能认定.最近,由文化部中国传统文化促进会、亚洲珠宝联合会等单位主办的中华宝玉石文化高层论坛在北京人民大会堂举行.在论坛上,经过20余名国内知名玉器考古、收藏专家仔细观察、研究,并与南阳的独山玉矿样品反复对比、鉴定,认定制作于元代、现陈列于北京北海公园团城的“渎山大玉海”玉料为南阳独山玉.至此,一桩“千古悬案”一锤定音.

Apple, Amazon squeeze costs out of latest tablets

Apple, Amazon squeeze costs out of latest tablets

SAN FRANCISCO—Apple's iPad Mini and Amazon's Kindle Fire HD both carry bill of materials (BoM) costs that allow for higher initial profit margins compared to previous tablet offerings from Apple and Amazon, according to teardown analyses performed by market research firm IHS iSuppli.

An entry-level iPad Mini carries BoM costs of $188 and another $10 in manufacturing costs, bringing the total to build each unit to $198—not including additional expenses such as software, licensing royalties and other expenditures—according to IHS. The entry level iPad Mini retails for $329. Based on the ratio of cost to retail price, the iPad Mini is slightly more profitable on a percentage basis than the comparably equipped version of the new iPad when it was released in March, according to IHS. (UBM TechInsights performed a detailed teardown of the iPad Mini last week).
http://www.eetimes.com/design/microcontroller-mcu/4400479/Teardown--Apple-iPad-Mini

A separate teardown analysis by IHS on the low-end Microsoft Surface RT tablet found that the product is initially more profitable per unit than a comparably equipped iPad.

After initially losing money on every original Kindle Fire after the tablet first came out, Amazon reduced the BoM costs significantly in the updated Kindle Fire HD, according to IHS. The firm estimates that the low-end Kindle Fire HD carries a BoM cost of about $165, plus another $9 in manufacturing costs. The low end Kindle Fire HD retails for $199.

By contrast, according to IHS, the original Kindle Fire was estimated to carry a combined $201.70 BoM and manufacturing cost when it was first introduced. That product also retailed for $199 at the time. Amazon's stated goal has been to break even on the Kindle Fire tablet hardware, allowing the firm to turn a profit on the content that users buy from Amazon.

浅谈玉雕的美学含义

浅谈玉雕的美学含义

　　“玉”字在人们心目中是一个美好,高尚的字眼,在古诗文中,常用玉来比喻和形容一切美好的人或事物.“书中自有黄金屋,书中自有颜如玉”、同时,玉字的妙用也使许多人,物,事,景为之增辉生色.至于玉颜、用来赞美美人姿色,此外形容人的风致还有“亭亭玉立”、“玉树临风”、“玉洁冰清”,玉总是和美好的事物联系在一起. 玉又是和平的象征,至于玉色纯净,质地坚密,也常用它来比喻贞操,节义,如“守身如玉”、“玉洁冰清”、“宁为玉碎,不为瓦全”.

　　玉,还被广泛用来描写大自然的景色.一些纯白素雅的花,常在其名之前冠以“玉”字,如玉兰花,玉茗等；以“玉龙”比喻漫天大雪,也颇为壮观.

　　从中国古代国家政治理论角度释义；从地理上讲,玉被推崇为天地万物的主宰；从成因上论,玉被解释为天地之精华；从礼仪上曰,玉被标榜为道德的楷模；从功能上说,玉被珍视为辟邪除祟,延年益寿的神物.

　　玉雕在美的追求方面集中表现在形式美方面.离开了形式美就称不上玉雕的创作.玉雕的创作是通过对原材料艺术的加工,使贵重的玉石和高超的技艺有机的结合起来,从而产生浓郁的趣味性和欣赏性.也就是说,玉雕创作是按照形式美的规律组成的艺术形象.

　　玉雕与国粹京剧艺术同样重欣赏轻情节,重形式轻内容,讲究形式美.玉雕创作当然要反映生活,表达一定的思想内容,但在程度、形式和表现手法上都与绘画有所区别,它是用高度地概括、夸张、寓意、象征的手法来表达的,如四季花卉同时开放,日月同时生辉.

　　玉雕的形式美可以归纳为三个方面:原材料的质地美、外形形式美、结构形式美,现在就这三方面作重点介绍,旨在对玉雕作品的欣赏有一个启发.

　　1. 1原材料的质地美

　　自然产生的事物具有美的特性,玉石材料本身的物理属性、材料的质地美,构成了天然的美感.

　　一块玉石通常呈现出多种颜色,它们颜色变化规律一般体现为多色美,如:色条、色块疏密的变化可以显示一定的节奏感.玉雕中的审美情趣在节奏的基础上赋予一种情调的色彩便形成韵律,韵律能给人以情趣,满足人的精神享受.玉的颜色韵律可用不同颜色在一定方向重复出现的规律来认定.例如虎皮玉的花斑纹很像老虎毛的花纹变化,斑驳陆离是指说不出变化的规律,但又很美的多色变化.

　　这也是玉雕得天独厚的优越条件.一件成功的玉雕作品就是充分利用并发挥原材料的质地美.这涉及到玉雕设计制作上的一些技术问题.其基本要点就是挖脏去绍,突出玉石之美,反璞归真.在设计创作法则上就是量料取材,因材施艺.

　　1.2外形形式美

　　就是整个外形构成的形象.玉石透明度、光洁度较强,细节刻画不大显眼,这就应该在外形上下工夫.以充分暴露的外型来刺激视觉,打动心灵.同时还应注意繁简、疏密、虚实、动静的对比关系,从而达到完美的效果.

　　1. 3结构形式美

　　在玉雕制作中,在形象刻画上都要求结构明确、肯定具体、细致以及来龙去脉交待清楚,要注意一叶一鳞、一羽的细节刻画,像表现发须总是丝丝分明、一丝不苟.对于代表性、关键性的细节和折关系更是明确、具体.比如:人物的衣领、衣袖、飘带,花卉的花头、叶子,无论怎样概括、夸张、变形或简化取舍,但对基本的结构关系,动态关系、生长规律、起伏变化都应交待的十分明确、肯定.

　　实践证明,玉石只有经过琢玉艺人的巧妙构思和鬼斧神工般的琢磨,方能成为一件精美的艺术品,才能最大限度地体现出其审美价值.任何一种艺术都有它的外在形式,作者的思想感情以及要表达的主题内容,都要通过某种形式来表现.所以形式美在任何艺术创作中都占有重要地位.

　　玉器造型之类的美学原则:1、对称原则；良堵文化的玉宗是对称原则运用的典范.2、虚实原则；龙山文化的玉龙等,镂空雕造型、动静相话、虚实相生、是中国艺术精神的源头之一.3、色,材型的充一原则；战国以来的俏色玉器是玉器审美潜力的充分体现.

　　玉器纹饰是造型的有机组成部分,造型与纹饰,内容与形式的统一相得益彰,融为一体的.数千年的玉器纹饰,以主题意韵可以宏观地概括为；新石器时代的神秘性(龙山,红山,良堵文化中的玉兽面纹),商周时代的礼仪性(六瑞,六器的用玉制度所要求),战国汉代的多彩性(几何性,兽而纹的变幻无穷,表现纹饰的绚丽多彩).唐宋时代的兼融,明清时代的风俗性(大量表现文玩雅兴,示警风俗的题材和纹饰表现于玉器中.

　　对于一件艺术品的欣赏所受到经验与知识的限制,使我们往往迷失在它的外在的形式里.对于这种美术作品的欣赏,人们常常被它外在的形式所感染,如造型之拙朴、雕琢之祖细、线条之简练、以及外在之张力,气氛之神秘等等,如何透过这些表层的东西去认知它内在的含义,从而探寻它的规律与特性,这便需要我们对中国传统文化有比较深的了解.

　　人们的审美需求的变化起了重要的作用.从良堵文化审美的玉棕,到汉代玉器简练的“汉八刀”,造型中所蕴涵的艺术和美感因素有了极大的发展.对于玉材和玉器制作工具与方法的制约的突破,也并不单单是对物质材料规律把握与发明(发现)方面的进展,同时也有“按照美的规律来创造”.

　　我们对玉的审美形态可归结为；质地色彩美一器形纹饰美一象征美之三位一体的模式.早期玉材料都是先民的在长期的运用石器的过程中发现大自然中对那些质地细腻、坚韧、润泽、晶莹、色泽鲜艳的珍贵称有的美石.材质美是玉的最基本的审美形态.玉从石中分离来,正是人们从玉石材料本身的物理化学性质的特殊性加以审美的结果.

ARM, Imagination divvy up MIPS

ARM, Imagination divvy up MIPS

NEW YORK -- MIPS Technologies, which had been on the block for almost a year, finally found buyers in a complicated deal involving Imagination Technologies and ARM.

Imagination said Tuesday (Nov. 6) it has agreed to buy MIPS' operating business for $60 million. Under terms of the deal, the U.K. graphics IP vendor will gain 160 engineers and 82 MIPS patents. The move is viewed as a way for Imagination to beef up its CPU core expertise while defending its graphics lead. It would also position Imagination to competing against ARM, which has been pursuing its integrated CPU-GPU solution strategy.

Separately, ARM said it will lead a consortium buying the rights to the MIPS portfolio of 580 patents. The consortium, called Bridge Crossing LLC, will pay $450 million in cash to purchase the rights to the portfolio, of which ARM will contribute $167.5 million.

ARM and others in the consortium are hoping that the deal will reduce the risk of infringing any MIPS patents. The consortium will make available licenses to the patent portfolio to companies outside the consortium, ARM said.

"ARM is a leading participant in this consortium, which presents an opportunity for companies to neutralize any potential infringement risk from these patents in the further development of advanced embedded technology," ARM CEO Warren East said in a statement. "Litigation is expensive and time consuming and, in this case, a collective approach with other major industry players was the best way to remove that risk."

Chip sales on pace to decline 5% in 2012

Chip sales on pace to decline 5% in 2012

SAN FRANCISCO—Worldwide semiconductor sales reached $24.8 billion in September, up 2 percent from August but down 4 percent compared with September 2011, according to the Semiconductor Industry Association trade group.

Third quarter chip sales totaled $74.4 billion, up 2 percent compared with the second quarter, SIA said. But sales year-to-date are still running down close to 5 percent compared with the first nine months of 2011, the group said.

"Semiconductor sales increased from August to September and from Q2 to Q3 as the industry continued to exhibit relative steadiness in a choppy global economy, but the global industry remains behind last year's pace due to lingering economic headwinds," said Brian Toohey, SIA president and CEO, in a statement.

Regionally, chip sales increased by 6 percent in the Americas on a sequential monthly basis, marking the region's largest increase since May 2010, the SIA said. Sales also increased from August to September in Asia Pacific (1.6 percent), Europe (0.7 percent) and Japan (0.2 percent), but all four regions lagged behind September 2011 sales, the SIA said.

    评定翡翠的品质优劣，可谓是认识翡翠的一项重要也是最基本的内容。但翡翠的品质划分一直以来是最为困难的工作，历来就有“千种玛瑙万种翠”的说法。所以对翡翠质量优劣的鉴别，堪称是失之毫厘、谬以千里。所以在翡翠行业界内，是不会对翡翠进行准确数字的估价的。比如说顾客朋友要鉴定一款手镯，专家会帮你鉴定，但是若要问准确价格，无论会是谁都说不上来准确的价格，所以翡翠忌讳估价。

福禄寿翡翠手镯类型寓意、价格、图片赏析 玉观音_玉貔貅_价格_图片_收藏_鉴赏—妙瑞可翡翠网

    在我国民间，一直传说福禄寿是三位仙人，即福星、禄星、寿星。所以当以“福禄寿”来命名的翡翠首饰品，就会显得寓意深远。

一、福禄寿翡翠手镯的类型及寓意

    在此处我们所说的福禄寿手镯，第一是指具有美好寓意的手镯，第二则是指翡翠手镯中的三种颜色，也就是三彩颜色，就是一款手镯中最难同时具有的红翡、绿色、紫罗兰色三种颜色。随着翡翠手镯在我国民间开始普及被佩戴的时候，国人就为这样具有三种颜色的翡翠手镯命名成福禄寿翡翠手镯。也是寓意了健康长寿、福运亨通、升官发财的意思。当然现今人们购买福禄寿手镯，并不是单纯的看它的寓意，而是当福禄寿手镯的三种颜色分布均匀、色泽比例好的时候，尤其是三种颜色的深浅度和浓、阳、正、俏、匀度都基本上一样时，再加上种好质地好的话，那么这样的手镯是很难见到的，就会显得极其珍贵和漂亮。从远观而来，会有一种震慑人心底的感觉，会吸引很多人的目光和心跳。

    当然国人还会比较喜欢最为传统的三彩福禄寿翡翠手镯，这里的三彩福禄寿翡翠手镯就是红色为上佳，白底搭上鲜绿色的色泽，这三种色泽就是人们比较喜欢和推崇的。还有另外的一种三彩福禄寿翡翠手镯，颜色是绿、红、黄三种颜色的手镯，是我国沿海一带、两广、海南台湾人比较喜欢的类型。如果这样的三种颜色生的比较好的话，那么价格也是极其高的。

    福禄寿翡翠手镯除了有三彩的颜色之外，还会偶尔可以见到“大四喜”的手镯，这类型的手镯要求颜色必须要蕴含四种以上，这样的手镯基本上都已经被私人收藏，翡翠市场上基本见不到影子。还有我们常说的“五福临门”风餐露宿翡翠手镯，更是极品的翡翠手镯，染色要达到五种以上，例如是红翡、黄翡、紫罗兰色、绿色、白底加蓝或者是加青色，这类型的翡翠手镯就是全世界的收藏家都为之疯狂的，一般只在超大型的翡翠百脉会上才可以见到这些福禄寿翡翠手镯的踪影。

二、福禄寿翡翠手镯的价格

    福禄寿翡翠手镯的价格并非像其它网站上吹嘘的天花乱坠般，什么价值连城，甚至价值上百万千万等等。福禄寿翡翠手镯在市场上还是偶尔可以见到的，一般出现这样的手镯时，福禄寿翡翠手镯的种质多是在冰种和糯种之间的糯冰种，有时候更多是冰种的福禄寿翡翠手镯，价格也就在几千元到上万元之间波动。但如果是极品的福禄寿翡翠手镯，则是要在一些大型的拍卖会上才可以见到。

Microsoft Surface RT more profitable than iPad

Microsoft Surface RT more profitable than iPad

SAN FRANCISCO—Microsoft Corp.'s Surface RT tablet generates a higher profit per unit than a comparable version of Apple Inc.'s wildly successful iPad, according to a teardown analysis performed by IHS iSuppli.

According to the IHS Teardown Analysis Service, the Surface RT model with a minimum of 32 gigabytes of NAND flash memory and an optional black Touch Cover carries a bill of materials (BOM) of $271.00. Adding in $13 in manufacturing expenses, the total cost to make each Surface rises to $284, according to IHS.

Microsoft retails the 32-gbyte version of the Surface with the Touch Cover for $599, generating a profit of $315 per unit, according to the IHS analysis. Even at a price of $499 without the Touch Cover, Microsoft will generate a profit margin that is greater than the low-end iPad in both percentage terms and on a per-unit basis, according IHS.

The IHS teardown of the Surface RT found components made by chip suppliers including Samsung Electronics Co. Ltd., Freescale Semiconductor Inc., Atmel Corp., Nvidia Corp. and others, IHS said.

Slideshow: Emerging Technologies that will change the world

Slideshow: Emerging Technologies that will change the world

[EE Times is celebrating its 40th anniversary, with special articles to celebrate the innovators who made the electronics industry what it is today, as well as the visionaries who are taking it forward. Look for more stories and a special section, coming soon.]

We picked ten technologies representative of trends which we expect will redefine our industry as well as the way we expect to interact in an increasingly interactive world. Admittedly, there are dozens of other examples we could have chosen with equal validity. We welcome your comments on our choices.

A few software-related trends were included because they are enabled by electronic technologies. We intentionally resisted including the deluge of “social media” and related trends that are merely popular uses of electronic devices.

Some of the predictions here are controversial -- such as “Death of the PC” -- but please try to be tolerant. Remember that few agree on the shape of the future, except perhaps that it will mostly include revolutionary changes nobody predicted.

Someday My 3-D Princess Will Come

3-D chips are one of those perennially "almost there" technologies, but are bound to become commonplace by 2023. Between now and then the 2.5-D Interposers will provide a buffer that solves the same problems without the fabrication headaches. Interposers interconnect multiple 2-D die on a silicon substrate that rivals stacking die in speed and energy conservation, but which lays them out side-by-side like a traditional PC board, only smaller. However, by 2023 stacked die using through-silicon-vias (TSVs) will be commonplace, such as the Hybrid Memory Cube (HMC) developed by Micron. Initially the bottom logic layer will be manufactured by IBM and shipped to Micron for stacking memory die. The HMC is being promoted by a consortium whose members include Altera, ARM, HP, IBM, Micron, Microsoft, Open Silicon, Samsung, SK Hynix and Xilinx.

SMIC posts record sales

SMIC posts record sales

SAN FRANCISCO—Chinese chip foundry Semiconductor Manufacturing International Corp. (SMIC) Monday (Nov. 5) reported record sales that exceeded analysts' expectations for the third quarter as the firm continues to benefit from rapid growth of the communications and consumer sectors in China.

SMIC (Shanghai) reported record third quarter sales of $461.2 million, up 9 percent from the previous quarter and up 50 percent compared to the third quarter of 2011. The foundry reported a net income of $12.2 million, up 68 percent from the previous quarter and up compared to a net loss of $87.9 million in the year-ago quarter.

SMIC's third quarter sales beat consensus analysts' expectations of about $440 million, according to Yahoo Finance.

SMIC's record sales announcement came just days after Taiwan Semiconductor Manufacturing Co. Ltd., the largest foundry vendor, also reported record third quarter sales. It was also the second consecutive quarter of record sales for SMIC, which also reported record results for the second quarter.

SMIC said it expects sales for the fourth quarter to be between $461.2 million and $470.4 million, flat to up 2 percent compared with the third quarter.

Tzu-Yin Chiu, SMIC's CEO, said through a statement that SMIC expects to achieve record sales in 2012. "In the past two quarters, we successfully achieved our short-term goal: to fully utilize our existing capacity and improve efficiency," Chiu said. "Our medium-term goal of technology differentiation is on track. We've already seen the fruit of some initial results."

Chiu said SMIC is also on track to achieve its long-term goal to continue advanced technology development to serve expanding demand from the fast-growing China market while deepening its relationships with leading customers.

Visionaries changing the world in next ten years

Visionaries changing the world in next ten years

Predicting the future is always fraught with peril, but the visionaries featured here are boldly going where no one has gone before.

To be sure, the personalities featured in this slideshow are not unique--in each category dozens of other pioneers could have been used in lieu of those chosen. Nevertheless, the pioneering vision and unflinching dedication of those featured in this slideshow serve as a shining example of how to “do” the future right.

Please forgive us for including two “ringers” who are not human: Wireless@MIT (which features a photo of the futuristic center where two MIT visionaries work) and “Lucy” an animated avatar which exemplifies a futuristic trend.

David Shepler-IBM
David Shepler was the Jeopardy Challenge Program Manager at IBM Research (shown here giving pointers to the human contestants on how to compete against Watson--IBM’s pioneering artificial-intelligence technology). After Watson beat the reigning human champions on Merv Griffin’s NBC television game show “Jeopardy,” hosted by Alex Trebek, Shepler served as Chief of Operations for the Watson research team’s efforts to adapt its AI to the healthcare field. Now patients in the WellPoint network--the nation's largest health benefits provider--can use Watson to help make more accurate and informed medical diagnoses. Next, Watson is tackling financial services, government-mandate management and retailing. More recently, Shepler became program manager for IBM's Smarter Energy Research Institute, which is developing predictive analytics, system optimization and advanced computation models that will help define the smart grid of the future. Shepler lives in his net zero-energy home in New Paltz, New York.

漫谈寿山石微雕艺术

漫谈寿山石微雕艺术

　　寿山石微雕是在小颗寿山石材上雕刻细微的画面或文字.寿山石微雕的历史从清朝末年开始.清初,杨璇、周彬都曾在寿山石雕品的花纹僻处刻以小字,西门派薄意大师林清卿也常在所刻作品的草丛、石缝中以极细的笔划刻上自己的姓名和制作年月.以后有人在印章方柱的四边,也以极细微的文字,雕刻古人诗词作为边款.

　　80年代,陈忠森以微中求精,进一步发展了“微雕”艺术.陈忠森自20世纪60年代潜心微雕艺术,微中求精,作品“微”到需用功率放大镜才能看清楚.他不但能在微雕中表现真、草、隶、篆,人物,山水,花鸟,乃至彩墨抽象画,而且所刻的字,点、划、间架结构极其精妙,其操刀金石韵味十足.书法家启功赠以“铁笔”称号.比如说王羲之的《兰亭序》全文,竟能在一颗1立方厘米、比大豆大一些的田黄石一个平面上全部刻完,所以他说是“艺在微”.

　　寿山石微雕书法和国画首先对创作用材十分讲究,被雕刻处的石质要绝对精纯,含不得半点砂格和裂纹.其次,应该具备既尖又锋利的细刀.第三,要求雕刻者有精熟的书法和国画功底,有时眼力已不敷其用,只能凭“意念”和运笔走势去雕刻.创作者要进入高超的艺术境界,聚精会神,屏息凝神,把训练有素的美感,倾注于刀下.第四,要有扎实的基本功.微雕力求用刀稳、准、狠.微雕的刀即是笔,功力不足,因微失控,刀不达意.微雕,见大显丑,字之歪斜,行之不齐,画之失准,配之失调,都是创作者应避免的.第五,应把握刀具与石材所产生的线条变化的艺术效果.

Why don’t start this specific audio learning tutorial to go to somewhat regarding the sort of record you need to start together with. Its fair to say nevertheless the initial thing you must do will be make certain that most likely working together with the ideal audio tracks quality achievable. Period different tracks and also render these in to a Trend or perhaps AIFF record. Tend not to work together with a great MP3 record unless really necessary since you’re previously letting go of several top quality.

When you have your current rendered register for your current music, turn on your current audio enhancing software for ones and load that will file as its very own the path. Make sure you unwarp that will file if possible to ensure it is not getting smaller to match the particular default pace of your respective audio tracks application.

Moment for the main a part of this specific audio learning article: the particular learning period. This is how outcomes like compression setting, reverb, and also EQ be given enjoy. One of the most beneficial tool with a learning engineer’s fingertips is likely to be equalization which usually splits the particular audio guide of your respective music into different ranges or perhaps “bands”. Generally many equalizers make use of a a few band create regarding reduced, middle, and also heights, even though several equalizers make use of a several band variety to offer you a lot more control within the middle collection.

As soon as you separation the particular spectrums of your respective audio tracks, it is possible to change them independently one at a time to improve or perhaps diminish the effects and also presence that will range or perhaps a part of that will range provides within the complete combine. Small adjustments different runs yields diverse final results. As an example, increasing time ending can give your current track a clear bassier and also thicker sculpt and getting rid of it will eventually give you a record an even more aluminum-like and lightly thin and also treble noise.

Increasing positive aspects ending will deliver an even more crispy properly getting rid of it will eventually supply the feeling your music will be muffled. This is the reason plenty of technical engineers will generally improve the high-end yet a word regarding caution as you enhance that collection an excessive amount of after that your noise should come around as being also aluminum-like and lightly thin.

Reverb can be another well-liked effect I described and works to right a designated sound song and present that more area. Incorporating or decreasing the particular reverb around the the path will deliver different noises, also, so it is generally done to the particular artist’s tastes and often done in the mixing period because of this.

内蒙古哈民史前聚落遗址发现人骨遗骸玉器

内蒙古哈民史前聚落遗址发现人骨遗骸玉器

　　新华网呼和浩特11月4日电(记者 于嘉)近日,被评为“2011年度中国十大考古新发现”的内蒙古哈民史前聚落遗址出土大量非正常死亡的人骨遗骸和精美玉器.考古专家表示,这些人骨遗骸和玉器的发现在史前遗址中极为罕见,并为揭示这处聚落被废弃的原因、复原史前人类生活原貌及研究古代玉文化提供了宝贵材料.

　　哈民史前聚落遗址位于内蒙古自治区通辽市科尔沁左翼中旗舍伯吐镇,北靠新开河,南望西辽河,介于大兴安岭南麓与松辽平原之间,年代距今约5500年.2010年,内蒙古文物考古研究所联合吉林大学边疆考古研究中心开始对其进行大面积有计划的考古发掘.

　　据考古队领队、内蒙古文物考古研究所研究员吉平介绍,在2012年的发掘工作中,考古人员共发掘1700平方米的遗址面积,清理房址11座、墓葬6座、灰坑18座、环形壕沟2条,出土遗物达500余件.其中,最引人注目的是大量非正常死亡人骨遗骸和精美玉器.

　　吉平说,考古人员在5座房址内共发现50具人骨遗骸,它们大多凌乱堆放,并且有被火烧的痕迹.同时,2条具有防御功能的环形壕沟内还出土7具姿态各异的人骨遗骸.“这些都展示了遥远的史前年代这里发生过一场杀戮或瘟疫,对解释这处聚落的废弃原因具有重要意义.”他说.

　　此外,考古人员还发现了44件玉器,均出土于房址内.主要器形有玉璧、双联璧、勾云形玉佩、兽首匕形器,以及各种坠饰,其中一件匕形器长15厘米,选料讲究,制作精美.值得一提的是,兽首匕形器、方形玉璧在此前的同时期史前遗址考古中从未出土过,属于哈民遗址独有的发现.

　　“这些玉器大多发现于人骨附近,可能被当时的人们所佩戴,也可能是史前人类某种身份的象征.而且这处聚落很可能遭受过巨大灾难,导致它在极短时间内被废弃,从而使大量玉器被瞬间埋藏,至今保存较好.”吉平说.

London Calling: Is GCC on the wane?

London Calling: Is GCC on the wane?

I doubt that the Gnu Compiler Collection (GCC) will go away any time soon. But it is notable that the 25-year old open-source initiative is facing some competition and rivalry – most notably from LLVM. LLVM is an open-source initiative similar to GCC but one that is favored and pushed by the significant force that is Apple.

The Free Software Foundation distributes GCC under the GNU General Public License. This is a license for royalty-free general use but requires that derived works can only be distributed under the same license terms.

GCC, which originally stood for Gnu C Compiler – because only the C software programming language was supported – has played an important role in the growth of free software and as a first port of call for those wishing to add compiler support to hardware. It therefore plays a significant role in embedded development and the world of microcontrollers.

But all things have their season and it may be that GCC's significance will now begin to reduce over time. Or it may respond to competitive pressure being brought to bear by LLVM.

One reference point I can give you is XMOS Ltd. (Bristol, England), a developer of event-driven, low latency multicore processors. XMOS has recently started to reposition the company as high-end microcontroller company. There's been no significant change in the hardware it sells as yet but the company recently reworked its entire line of development tools and moved them from GCC to LLVM.

The XMOS move reportedly produced improvements in compile time of about 40 percent, in run-time performance of about 60 percent, and reduced code size by 17 percent, over the previous GCC-based compiler.

LLVM used to stand for low-level virtual machine but now has little to do with traditional virtual machines, although it does support runtime as well as static compilation. LLVM began as a research project at the University of Illinois Urbana–Champaign, under the direction of Vikram Adve and Chris Lattner with the goal of providing a three-phase compiler strategy capable of supporting both static and dynamic compilation of arbitrary programming languages.
