For the first time, a 40nm-node, 2x logic density, 3.8x operation speed, and 3x power efficient, nonvolatile programmable logic (NPL) is demonstrated by using Cu atom switch for configuration switches. The switching characteristics of the atom switch are kept in scaling down to 64/32nm device area, and an improved PSE reduces set voltage while keeping low leakage current, enabling core transistors...
To ascertain flashover mechanism of the roof external insulation in high-speed airflow environment, breakdown characteristics and mechanisms of short needle-plate air gaps in high-speed airflow were investigated based on an artificial experimental wind-tunnel platform We obtained the breakdown characteristics of the air gaps in wind sand environment by studying the influences of sand mass concentration,...
Microwave assisted magnetic recording has been proposed as a next generation recording technology, which utilizes a spin torque oscillator (STO) imbedded between write pole and trailing shield for generating high frequency ac field [1] [2].
Programmable Logic (PL) with a high logic density is demonstrated by cross-bar (xbar) of atom switches, which are programmed through logic transistors. The PL has 4 4-input LUTs to minimize area-delay product owing to small area & capacitance of atom switch. Xbar with 50% and 100% populations mixed and programming lines shared architecture achieves a 2× higher logic density comparing to a commercial...
A fully 400°C-processed, standard Cu-BEOL compatible, robust Cu atom switch has been developed featuring an over-400°C high thermally tolerant polymer-solid electrolyte (TT-PSE). Hydrocarbons that have weak chemical bindings in the PSE are selectively eliminated in the TT-PSE, resulting in higher thermal stability. The TT-PSE also gives higher breakdown voltage (+1V) with keeping low set voltage (2V)...
A non-volatile programmable logic (NPL) with atom switch significantly accelerates performance of micro-controller unit. A low-power 32bit-CPU using a 65 nm-node Silicon-on-Thin-Box (SOTB) CMOS performs 1.95 DMIPS/MHz and 33 μW/MHz on 25 MHz and VDD=0.4V. When a software process in the CPU is offloaded to NPL, the 9 times faster processing speed and 3 times higher energy efficiency are realized. A...

This paper looks at how automatic load transfer may be used as a possible planning tool to help deliver faster connections for customers. A trial on an area of overhead line Network is presented to show how improvements in % feeder utilisation may be realised by changing the location of the open point. The reported Network data is compared to calculated data under two different configurations over...
Compressive sensing (CS) is a novel signal sampling theory and it can recover sparse or compressive signals with lower rates than their Nyquist rates. Greedy pursuit algorithms are important recovery algorithms in CS. In this paper, we study the performance of subspace pursuit (SP) greedy algorithm and propose a modified SP termed as regularized multipath subspace pursuit (RMSP), which divides the...
Different dose rates of implant can lead to different amorphous layer thicknesses for amorphizing implants and may influence device performance. In addition, it has to be noticed that the batch type spot-beam was proved as divergent beam with large angle divergence which is different from single wafer spot beam and also takes into consideration by both bare wafer and also real device leanings. In...
The cost and limited flexibility of traditional approaches to 11kV network reinforcement threatens to constrain the uptake of low carbon technologies. Ofgem has released £500m of funding for DNOs to trial innovative techniques and share the learning with the rest of the industry. One of the techniques under study is the addition of Energy Storage at key substations to the network to help with peak...
This article reviews the studies on the influencing factors of the establishment mode choice in international market entry, based on 12 empirical studies published from 2000 to 2011 published in five top journals in the international business and general management & strategy fields. Following a central theme-based organizing approach, we suggest a strategic management process framework with five...
The practice and future plans of smart grids in Europe are discussed in this paper. Firstly, the features of current power grid in Europe are introduced. Then, the plan of future European power grid with high penetration of renewable energy is introduced. After that, the practice of smart operation of interstate power grid is given. Finally, the most concerned issues and plans for the smart operation...
In this paper, we proposed a novel approach to shape classification. A new shape tree based on junction nodes can represent the global structure in a simple way. The statistic distribution of junctions can be learned by merging the shape trees. In the process of learning, context of a junction node is obtained to improve the rate of classification. We illustrate the utility of the proposed method...
This paper addresses the quantification and allocation of peaking costs of hydrothermal power systems under electricity market environment. Mixed-integer linear formations of market scheduling of hydrothermal power systems is described, with the maximum ramping up/down limits and minimum start/off time limits of thermal generators, as well as the generation quantity and hydraulic vibrations of hydropower...
A high resolution EEG study was conducted on healthy human subjects during video game play. Throughout the game playing experiment short time segments of spontaneous activity were recorded. Spectral analysis was performed on these segments for the theta-wave (4-8 Hz) and alpha-wave (8-13 Hz) bands to investigate the modulatory effects of long-lasting game play and the dynamic changes of spectral contribution...
