Three dimensional IC (3DIC) is becoming practical in today's consumer electronics designs. However, one major problem remains in design synthesis and flow: how to model heterogeneous die(s) with major logic die for power synthesis and signoff. This work provides a realistic model and principle for heterogeneous dies power network for 3DICs. It is based on given abstract or early stage information...
For de novo transcriptome analysis, choosing a closest reference model specie in terms of evolutionary distance is a general approach for gene mapping and genome annotations. However, not every selected reference model species possesses comprehensive genome annotations and curated information, and the total number of mapped genes from the selected reference species could not be fully expected either...
Increasing supply chain players seek to run business in a responsible way. This work stands from a supplier's point of view by considering a two-stage supply chain structure in which a responsible supplier produces a responsible component (or raw material, ingredient) through an entrepreneurial process and exploits the business opportunity (e.g., market expansion) to sell it to downstream buyers....
When the load of high voltage electricity consumer is low, the line will send large of capacitive reactive power to the power grid for the existing of distributed capacitance, causing lower power factor by the side of metering point substation. The electricity expenses of consumer will increase proportionally. With the case of more electricity expenses for the light-load line, this paper has established...
The network distance education is a new form of further education based on computer information technology, its advantages lie in breaking the limits of time and space, besides stimulating students the initiative of learning. However, it influenced by traditional academic education, so the advantages of the above model don't get fully exerted. The text analyzes from these above problems, it based...
A novel permanent-magnet (PM) linear motor which composes of two isolated movers and one single stator is proposed in this paper. It is suitable for tasks requiring multiple drive motors. Each mover can produce independent force and flexible motions by interacting with the stator poles. Compared with conventional multi-motor driven system, it achieves more compact size, and thus increases the system...
Pipe strings, as critical components in oil and gas industry, are highly susceptible to axial cracks for stress corrosion and fatigue damage. The conventional detection methods, such as magnetic flux leakage and magnetic particle inspection, are inadequate for accurately detecting a narrow axial crack. Alternating current field measurement (ACFM) technique is an electromagnetic inspection method capable...
A slow-paced attack, such as slow worm or bot, can remain undetectable indefinitely by slowing down the pace of its movement. Detecting slow attacks based on traditional anomaly detection techniques may yield high false alarm rates. Since attacks are usually controlled by pre-programmed computer codes, their behaviors have regularity. In this paper, we track outbound connections of hosts by using...
A novel dual Halbach array is proposed in this paper to increase the output performance of tubular linear machines. The magnetic field distribution in three-dimensional (3D) space is formulated with Bessel functions analytically. Following that, the modeling of force output for linear machines with three-phase windings is carried out based on Lorentz force law. The formula component of force ripple...
In this paper, we propose a fast and accurate thermal aware analytical placer. Thermal model is constructed based on Green function with enhanced DCT to generate full chip temperature profile. Unlike other previous thermal aware placers, our thermal model is tightly integrated with a flat force directed placement. A thermal spreading force based on 2D Gaussian model is proposed to reduce maximum on-chip...
The dynamic equations of a micro-positioning Scott-Russell (SR) mechanism associated with two flexible hinges and an offset are developed to calculate the output responses. Both rigid and flexible hinges are considered to explore the results. The manufacturing inaccuracy of the SR mechanism definitely causes geometric offsets of flexure hinges, and affects the displacement amplification and straight-line...
The demand for high performance information dissemination is increasing in many applications, such as e-commerce and security alerting systems. These applications usually require that the desired information be matched between sources and sinks based on established subscriptions in a timely manner while a maximal system throughput be achieved to find more matched results. Existing work primarily focuses...
A ball-joint-like three-degree-of-freedom (3-DOF) spherical actuator which features a ball-shaped rotor with multiple permanent magnet (PM) poles and a spherical-shell-like stator with air-core coils is proposed to achieve omnidirectional smooth motion in only one joint. Unlike previous study in which dihedral-shaped PMs are employed as the rotor poles, this spherical actuator takes advantage of cylindrical-shaped...
Because of the limited battery power of wireless sensor network node, energy conservation is a key issue. This paper improves LEACH algorithm. Through taking into account the energy state and one-hop neighbor nodes of nodes, the improvement algorithm optimizes cluster head selection, and effectively reduces the possibility that the low energy or poor location nodes are elected the cluster heads, further...
This paper introduces a semi-analytic model that provides a simple and quick solution for analyzing large deflection beam-based flexure joints of various configurations. Such configurations consist of a beam-based flexure joint coupled with any rigid-link length. This model provides an accurate approximation of large deflection beam-based flexure joints achieving a deviation as low as 0.06% when compared...
Power control is becoming a key challenge for effectively operating a modern data center. In addition to reducing operation costs, precisely controlling power consumption is an essential way to avoid system failures caused by power capacity overload or overheating due to increasing high-density. Control-theoretic techniques have recently shown a lot of promise on power management thanks to their better...
For supplying adequate driven force with high operational precision in semiconductor manufacturing industry, construction of a low cost device that can be integrated with the micro-electromechanical system (MEMS) fabrication scheme has been investigated. With both the degraded material property after electroplating process and the geometric constraints of MEMS constructions being considered, magnetic...

We also develop analytical models to determine the tracking and locating costs for mobile switches. The fitness function is formed by these analytical models. Load balancing and the call-to-mobility ratio...
