2013年4季度，世界经济复苏势头渐显。从国际经济形势来看，美国经济受益于个人消费、出口、非居民住宅固定资产投资以及私人库存投资的增加而持续增长，欧元区在经历了债务危机的打击之后正在慢慢恢复元气，相关数据也表明欧洲经济正处于加速增长的轨道上，而日本经济则受制于私人部门消费增长没能达到预期和出口不振的影响，增速明显低于预期。从国内形势来看，中国经济增速稳中向好。根据国家统计局的初步核算，2013年全年国内生产总值568845亿元，按可比价格计算，比上年增长7.7%。国内经济的平稳运行，为电信业务收入的增长创造了良好的环境。2013年全年，电信业务收入实现11689.1亿元，同比增长8.7%，增速虽较上年回落0.2个百分点,但仍连续三年高于同期GDP增速。

2014年1月份，受上年基数较高和节假日因素的影响，我国电子信息产品进出口额同比出现小幅下降。电子信息产品进出口总额1050亿美元，同比下降4.4%；其中，出口630亿美元，同比下降2.3%，低于全国外贸出口增速12.9个百分点，占全国外贸出口比重为30.4%。进口420亿美元，同比下降7.6%，低于全国外贸进口增速17.6个百分点，占全国外贸进口比重为24.0%。

2013年,世界经济延续缓慢复苏态势,全球消费电子市场保持小幅增长,手机市场形势好于2012年.市场研究机构IDC称,2013年全球手机出货量达到18亿部,同比7.3%,增速比2012年明显提高;智能手机的快速增长是带动手机市场成长的主要动力,IDC称,2013年全球智能手机出货量首次突破10亿部,达到10.04亿部,同比增长38.4%,占手机整体出货量份额达到55%.与手机市场规模扩张相伴的是行业竞争进一步加剧,手机产业竞争由原先的单纯产品竞争演变为硬件、软件与服务的全方位竞争.面对市场与竞争结构的不断变化,我国手机企业积极应对,加快产品革新,提升服务质量,行业整体平稳运行,产量规模继续扩张,外贸出口稳步增长,效益质量持续提升,对我国电子制造业、软件业及通信业的发展起到了积极的支撑作用.

2013年，面对错综复杂的国内外政治经济形势，我国电子信息产业各级主管部门认真贯彻党中央、国务院“稳中求进”的经济工作总基调，坚持统筹稳增长、调结构与促改革之间的关系，加大政策预调微调力度，积极培育信息消费等热点领域，产业内骨干企业加快转变发展方式，不断优化产品与市场结构，全面深化转型升级，使得产业整体运行呈现平稳态势，生产保持较快增长，效益规模稳步提升，结构调整不断加快，为提高社会信息化发展水平和促进两化深度融合发挥了积极作用，在国民经济中的重要性持续提高。

1月份，我国通信业总体运行平稳,电信业务总量和业务收入增速回升。1月份，全国电信业务总量完成1411.3亿元，同比增长17.0%，比上年同期增速高3.6个百分点；电信主营业务收入完成947.1亿元，同比增长9.2%，比上年同期增速高2.4个百分点。

The Asia-Pacific ICT sector slowed over the six months under review, hampered by sluggish growth in China and India. Emerging countries such as Malaysia, Vietnam, Indonesia and the Philippines spent more on ICT, with governments budgeting to further develop high-tech ICT infrastructure. The ten leading Asian IT stocks were mixed over the six months to October 25, 2013, but most of them performed poorly, declining by an average 5.8%. Although Lenovo remained in a virtual tie for the top position in PC market, it shifted its “attack market” to mobile devices, which contributed to a significant portion of total revenues.Asia-Pacific merger and acquisition activity was low in both volume and value over the past six months, but the long-term outlook remains strong thanks to ongoing technology innovation.

Among all the harsh environment applications, high temperature applications have drawn lots of attention due to the emerging activity in automotive, turbine engine, space exploration and deep-well drilling telemetry. Silicon carbide has become the candidate for these harsh environment applications because of its wide bandgap, excellent chemical and thermal stability, and high breakdown electric field strength.

This work demonstrates a new technique for achieving high optical Q on chip, a fully-integrated tunable filter with ultra-narrow minimum bandwidth, and the effect of material choice and device design on optical Q, mechanical Q and phase noise in microring optomechanical oscillators.

This research aims at designing a non-invasive, low-cost, and portable imaging device for cancer screening. Conceptualization, architectural and system-level design, and finally implementation of the system called TUSI, Time-Domain Ultra-Wideband Synthetic Imager, are addressed. Using an array of closely controlled radiating silicon chips, acting as transceivers in microwave /mm-wave frequencies, this device transmits short “beam-steered” pulses and picks up reflections from tissue abnormalities (e.g. cancerous tissue). By processing the data from multiple transceivers, a larger aperture is synthesized. In essence, this imager probes the “electrical” properties of the tissue.

In this dissertation, we theoretically derived the local enhancement of the optical antenna and found that optimized radiation and small gap spacing are required for maximum field enhancement of the antenna. To address these parameters, we experimentally demonstrated three different designs of optical antennas. First, we report on applying a dipole antemma on a ground plane for radiation engineering. Secondly, we report on a patch antenna on gound plane for the uniform sub-5 nm gap spacing. Finally, we present a novel optical antenna design—thearch-dipole antenna—which has radiation efficiency and small gap spacing(5 nm) fabricated by CMOS-compatible deep-UV spacer lithography.

Aluminum nitride (AlN) Lamb wave resonators (LWRs) utilize piezoelectric transduction to ensure low motional resistance. The resonance frequency of a LWR is defined by interdigital transducer (IDT) pitch and is thus decoupled from the overall device dimensions. This fine frequency selection technique is enabled by adjusting the so-called AlN "overhang" dimension allowing control of relative frequency of Lamb wave resonators in an array to 0.1%. Experimental results suggest the center frequency of LWRs can be linearly adjusted by up to 5% with no significant effect on other resonator parameters includingQ,Rm,C0, andkt2. Closely and evenly spaced AlN Lamb wave resonators, without post-process trimming, demonstrate the potential to realize a pure mechanical, high performance, yet low power RF front-end system.

An uncommon architecture of a direct-coupled transmit/receive FMCW radar transceiver was investigated and implemented. The architecture uses a single dual polarization antenna to transmit and receive circularly polarized waves and implements a form of on-chip circulator by directing energy between common- and differential-modes on a symmetric waveguide structure.

Proposal a tool flow that enables a programmer to describe key applications kernels from a high-level description and then generate highly efficient software and hardware solutions from that description. Demonstrate of the effectiveness of our approach to hardware and software code-design by an in-depth case study in large vocabulary continuous speech recognition. Specifically, our results show an energy savings of 3.6×over that of a conventional mobile processor and 2.4×over that of a highly-optimized vector processor.

智慧城市是指以“强政、兴业、惠民、绿色”为目标，创新应用新一代信息技术和泛在宽带安全的信息基础设施，将城市中的信息化资源和系统有效整合，达到人与城市功能系统以及城市客观环境全场信息交流、智能响应、和谐共生的境界，构建具有可持续内生动力的绿色城市新形态。因此，智慧城市模型应该是“多维的，涵盖城市不同方面的智慧，并强调跨多个域的融合和互动的重要性”。
