As one alternative source of energy for the future, fusion power will be required to demonstrate that it can be a safe, clean and economically attractive option in an increasingly diverse and competitive energy marketplace. Top-level requirements have been developed and used to guide the development of fusion power concepts, most recently, the ARIES-RS conceptual power plant design based upon t...

We extend the former matrix rearrangement approach of the entangling power to the general cases, without requirement of same dimensions of the subsystems. The entangling power of a unitary operator is completely determined by its realignment and partial transposition. As applications, we calculate the entangling power for the Ising interaction and the isotropic Heisenberg interaction in the hyb...

A 128-channel digital autocorrelator spectrometer using four 32 channel low power CMOS correlator chips has been built and tested. The CMOS correlator chip uses a 2-bit multiplication algorithm and a full-custom CMOS VLSI design to achieve low DC power consumption. The digital autocorrelator spectrometer has a 20 MHz band width, and the total DC power requirement is 6 Watts.

Inertial energy scavengers are self-contained devices which generate power from ambient motion, by electrically damping the internal motion of a suspended proof mass. There are significant challenges in converting the power generated from such devices to useable form, particularly in micro-engineered variants. This paper presents approaches to this power conversion requirement, with emphasis on...

<p>The heart of the machining center design is spindle design, and one primary functions in a tool clamping system mechanism. The selection disc spring stack for mechanism an iterative process that highly depends on space availability, drawbar unclamp stroke length, standard force requirements. For example, even 0.1 mm may impact kN depending design. Hence time- intensive also needed care...

A novel TEM horn antenna placed in a solid dielectric medium is proposed for microwave imaging of the breast. The major design requirement is that the antenna couples the microwave energy into the tissue without being immersed itself in a coupling medium. The antenna achieves this requirement by: 1) directing all radiated power through its front aperture, and 2) blocking external electromagneti...

Traditional online wheel-set ultrasonic inspection method and inspection technology can not meet the new requirement of High Power Locomotive wheel-set online. In this article, features of locomotive wheel and defect distribution are analyzed, and a more strictly online inspection requirement is put forward. Based on which, an optimized multi arrangement of phased array and conventional ultraso...

In intrusion detection among different hardware approaches, memory-based architecture has attracted a lot of attention be-cause of its easy reconfigurability and scalability. In order to accommodate the increasing number of attack patterns and meet the throughput requirement of networks, a successful network intrusion detection system must have a memory-efficient patternmatching algorithm and h...

Requirements specification methods and techniques have hitherto mainly been concerned with promoting various representation formalisms for formally describing information systems, and discussing their expressive power. However, this approach concentrates only partially on the problem. A major issue is how to bridge the gap between ill-defined problem and application situations, and specificatio...
