As an efficient multi-core system structure, three-dimensional Network-on-Chips (3D NoC) opened a new filed of System-on-Chip (SoC) research. In this paper, we present an efficient routing algorithm for 3D NoC applications. This method is based on west-south-first routing algorithm and intra-layer routing has higher priority. We introduce the concept of possible deadlocked configurations and further...
From the perspective of national security, legitimate government agencies have long been committed to enforcing powerful surveillance measures on suspicious individuals or communications. This paper investigates a wireless legitimate surveillance system, where a full-duplex multi-antenna legitimate monitor aims to eavesdrop on a dubious communication link between a suspicious pair via proactive jamming...
Bridge is among the most important structures on high speed railway. The operation and management must meet the requirements in terms of reliability, availability, maintainability and safety. A prognostic and health management system used for bridges on high speed railway is first proposed in this paper. This new system is a user-oriented tool, providing guidance or information for inspection, repair...
This article introduces a new wind turbine, called resistance type vertical axial wind turbine (VAWT) with soft blades. The blades of the new turbine resist the wind and collect the power along the wind direction, while canceled the resistance against the wind direction. The new work mechanism was conceived to improve the aerodynamic performances of traditional VAWT. To prove the above supposing,...
This paper presents an efficient routing algorithm for 3D meshes without virtual channels. The proposed routing algorithm is extended from 2D east-first routing algorithm and based on network partitioning. It is proven that the proposed method is free from deadlock. In comparison of previous routing algorithms, the average degree of adaptiveness is higher. This feature contributes to higher communication...
This paper studied the influence of polyimide (PI) on the wafer warpage and electrical leakage in the wafer bumping structure and process. The wafers with different thickness PI and different PI coverage were built. And the warpage of these wafers was measured before PI coating, and after PI curing. According to the result, the thicker PI and higher PI coverage on the wafer induce larger wafer warpage...
The thermal problem is a challenge in recent Network on Chip (NoC) designs due to its great impact on the network performance and reliability, especially for 3D NoC. In this work, we design a virtual channel based fully adaptive routing algorithm for the runtime 3D NoC thermal-aware management. For throttling information collection, instead of transmitting the topology information of the whole network,...
We present a hybrid photonic-crystal fiber for phase-matched third-harmonic generation. Third-harmonic radiation is confined in a Gaussian-like mode by an all-solid bandgap microstructure, while outer hollow channels ensure guidance of pump radiation in fundamental mode.
We analyze the problem of computing a correlated equilibrium that optimizes some objective (e.g., social welfare). Papadimitriou and Roughgarden [2008] gave a sufficient condition for the tractability of this problem; however, this condition only applies to a subset of existing representations. We propose a different algorithmic approach for the optimal CE problem that applies to all compact representations,...
The rapid growth of wind energy is presenting great challenges to the traditional dispatch and control of power grid since the wind energy which has an adverse effect on peak regulation is intermittent, fluctuant and uncontrollable. To improve the consumption level of wind energy, this paper proposed a cost compensation mechanism to facilitate the demand side to participate in peak regulation when...
Battery Energy storage system (BESS) makes it possible for wind power to participate in pre-determined power dispatching. To deal with the variability and uncertainty of wind power, peaking constraints of BESS accounting for the effect of wind power on system dispatching are proposed in this paper. On the basis of that, an optimal capacity model considering investment costs, operational benefits,...
In this paper, a 13-bit serial to parallel GaAs digital circuit based on GaAs 0.15um Enhancement-Depletion(ED) PHEMT has been realized and measured. This serial to parallel circuit is designed for the 6–18 GHz T/R module, it controls 1-bit switch, 6-bit shifter and 6-bit attenuator. This GaAs logic circuit could reduce the size of T/R module chip and improve the integration degree of the system. The...
Wind power curtailment in winter of Northern China is mainly caused by the limited flexibility of combined heat and power (CHP) plants. Improving the profitability of CHP by heat storage is a promising alternative to increase the integration of wind power. Dispatching method of CHP and heat storage is proposed in this paper based on two linear models. The first model is used for the pre-judging of...
We experimentally evaluated the crosstalk impacts of cascaded ROADMs for SDM networks. Crosstalk induced Q penalties in 128 Gb/s transmission were compared for interleaved and grouped configurations, with 1–1.5 dB improvement for the interleaved setup.
This paper considers a wirelessly powered wiretap channel, where an energy constrained information source, powered by a dedicated power beacon, communicates with a legitimate user in the presence of a passive eavesdropper. The source is assumed to have multiple antennas, while the other three nodes are equipped with a single antenna each. Considering a simple time-switching design where power transfer...
Two fourth-harmonically pumped mixers are designed and fabricated on a 0.15 μm GaAs pHEMT process. A new tandem comb-compact microstrip resonating cells structure with excellent wide band-stop and slow-wave characteristics is designed for conversion loss reduction and size compaction. Instead of using conventional shorted or open stubs, equivalent capacitors and inductors are employed to save chip...
This paper presents a G-band balanced tripler using 0.1 um GaAs process. An anti-parallel diode pair (APDP) structure is applied in the tripler to obtain the third harmonic signal. The balanced architecture with two 90° Lange couplers is employed for doubling the output power, improving input and output impedance matching, as well as increasing the spurious suppression. The measurement results show...

The distances between DNA Transcription Regulatory Elements (TRE) provide important clues to their dependencies and function within the gene regulation process. However, the locations of those TREs as well as their cross distances between occurrences are stochastic, in part due to the inherent limitations of Next Generation Sequencing methods used to localize them, in part due to biology itself. This...
