2007 IEEE Workshop on Signal Propagation on Interconnects (SPI 2007)

In this paper we discuss a computational framework which allows for accuracy controlled capacitance extraction in the entire package model consisting of 2.9 million elements on the conductor boundaries. The capacity for simulation of large-scale interconnects is attained through parallel implementation of a tree-based hierarchical computational algorithm. The acceleration of dense matrix-vector product resulting from the Locally Corrected Nystrom (LCN) discretization of the governing integral equation is effected by means of the Barnes-Hut (BH) method. The kernel-independence of the latter provides for inclusion of the dielectric substrate into the computational model without increasing the model's size by means of creation of the pertinent Green's function databases for the substrate process.

Inkjet technology was used in a mass production process to form an alignment layer on high-temperature polysilicon TFT liquid crystal panels used in LCd projectors. This is the first-ever inkjet process for forming alignment layers in an LCd manufacturing process. Surface treatment, inkjet ejection, and post-print drying processes were integrated, and process conditions and printing materials were optimized, thereby sharply improving display quality while reducing process environmental impact.

Multimedia applications are driving wireless network operators to add high-speed data services such as Edge (E-GPrS), WCdMA (UMTS) and WLAN (IEEE 802.11a,b,g) to the existing network. This creates the need for multi-mode cellular handsets that support a wide range of communication standards, each with a different rF freguency, signal bandwidth, modulation scheme, etc. This in turn generates several design challenges for the analog and digital building blocks of the physical layer. In addition to the above-mentioned protocols, mobile devices often include Bluetooth, GPS, FM-radio and TV services that can work concurrently with data and voice communication. Multi-mode, multi-band, and multi-standard mobile terminals must satisfy all these different reguirements. Sharing and/or switching transceiver building blocks in these handsets is mandatory in order to extend battery life and/or to reduce cost. Only adaptive circuits that are able to reconfigure themselves within the handover time can meet the design reguirements of a single receiver or transmitter covering all the different standards while ensuring seamless inter-interoperability. This paper presents analog and digital base-band circuits that are able to support GSM (with Edge), WCdMA (UMTS), WLAN and Bluetooth using reconfigurable building blocks. The blocks can trade off power consumption for performance on the fly, depending on the standard to be supported and the reguired QoS (Quality of Service) level. © 2006 IEEE.

This paper characterize the power bus noise radiation through a cutout on the power/ground plane of printed circuit boards (PCB). Analytical model of the radiation is proposed and it is verified by a full wave simulation and experiment. Both the full wave simulation and measurement show good agreement with the model up to 3 GHz. The results show that the radiation through a cutout is substantial at the resonant frequencies.

A unique generating system for Gas heat pump system (GHP) is presented. The GHP is an air-conditioning system, in which the compressors are driven by a gas engine. The proposed system is applied to the outside unit of GHP to feed the electrical equipments inside. The system utilizes a permanent magnet synchronous generator, which is connected to the gas engine, to realize high-efficiency and small-size. The generator is controlled by a converter with sensorless control technology to eliminate the position sensor. Another major topic is the "free-run startup" technique to start the converter when the generator is rotating. The system configuration and principles of the techniques are set forth, followed by experimental results which show that the system works properly and successfully.

The cover demonstrates the innovation potential of bulk nanostructured materials obtained by severe plastic deformation (SPd) in various industrial sectors. The microstructure of Al wire processed by continuous SPd processing in ECAP-Conform together with a schematic illustration of an ECAP-Conform set-up are shown in the background. Further information about the perspectives of commercialization of bulk nanostructured materials produced by SPd processing can be found in the review paper by r. Z. Valiev et al. on page 527. The innovation potential is high for bulk nanostructured materials (BNM) produced by methods of severe plastic deformation and accordingly this report focuses on very recent developments demonstrating the potential of using BNM for advanced and functional applications in engineering and medicine.

An efficient computational method for the constrained multibody systems is proposed. In the proposed method, local parametrization method is employed to apply the same solution method for position, velocity, and acceleration analyses since the coefficient matrices for each analysis have an identical matrix pattern. The skyline solution method is used to overcome numerical inefficiency when solving large scaled equations. Subsystem partitioning method is derived systematically to perform parallel processing for the real time simulation. To show the numerical accuracy and efficiency of the proposed method, three numerical problems are solved. Copyright © 2005 by ASME.

development of navigation system employing intraoperative diffusion weighted imaging using open MrI

International Congress Series 2004年第C期1268卷 697-702页

In surgical removal of a malignant brain tumor, which is close to a pyramidal tract, diffusion tensor images obtained by preoperative magnetic resonance imaging (MrI) can display the spatial relationship between the tumor and the pyramidal tract. This image, however, is not appropriate to navigate the surgery because of brain shift due to surgical manipulation. We developed a navigation system employing intraoperative diffusion weighted imaging (dWI) using open MrI, which is the first trial with a 0.3 T scanner to aim at complete removal of cerebral tumors. A newly developed surgical coil has both functions of head fixation in surgery and a receiver coil in scan. The dWI of volunteers could display nerve fibers such as pyramidal tracts and corpus callosum under the optimized scan parameters. By refining navigation software, a physical position directed by the pointing device could be displayed correctly on three cross-sectional T1 (or T2) weighted images and three-dimensional (3d) dWI. Initial clinical evaluation of this system revealed that the spatial relationship between the tumor, the pyramidal tract, and the treatment position could be displayed correctly. Furthermore, the surgeons could recognize these positions intraoperatively and visually. The navigation system employing intraoperative dWI for a tumor and nerve fibers helped the surgeons remove the tumor and obviated postoperative disturbance such as motor paralysis. © 2004, CArS and Elsevier B.V.

For high bandwidth and low stand-by power ddr (double data rate) I/O interface, a new fully analog dLL (delay Locked Loop) are designed and implemented in 0.16 /spl mu/m drAM process. Utilizing a tracking AdC (Analog-to-digital Converter), a large stand-by current of the analog dLL is suppressed without losing locking information nor compromising jitter performance. Two-step duty correction scheme using multiphase clocks and phase mixing corrects an inherent duty-error of a system clock with more precision and speed, especially for a large duty-error. Proposed dLL has a 100 MHz/spl sim/520 MHz wide lock-range and a 65 psec peak-to-peak jitter and 0.064 psec/mv supply sensitivity at 2.3 v supply voltage consuming 1.1 mA of stand-by current.
