this paper presents the characteristics of programmed SONOS memory. the CHE and CHISEL programming mechanisms are analyzed and the effects of programming bias to the program speed and saturated VT under different program methods are studied. It shows that compared with CHE operation, CHISEL program has a lower voltage bias for the same program speed, and better threshold self-convergent character. the distribution of trapped charges in the silicon nitride layer after CHE or CHISEL program is also investigated. the research shows that the different charge distributions have different impacts to the I/sub d/-V/sub g/ and erase characteristics.

作者： Xiaoke Yan Caisheng Shi Baojun Zhao Peikun He Department of Electronic Engineering Beijing Institute of Technology Beijing China

In this paper, a dynamic programming (DP) method, concerning the edge detection of infrared (IR) target from a given field background, is proposed. It involves locally adaptive threshold technique and fractal theory. Firstly, optimal control function based on different fractal dimensions and gray level features on infrared image is created. the second step is to seek latent object point by locally adaptive threshold technique and to calculate the minimum cumulative cost matrix. Finally optimal and connected contours are determined by DP. Experiments with real targets show that the method can detect target effectively and reduce false alarm probability.

three-dimensional (3-d) surface models of human carpal bones obtained from Computed Tomography (CT) were used to investigate their kinematic behavior throughout the entire physiological range of motion of the human wrist joint. the 3-d motion of the bones was visualized graphically by the finite helical axis (FHA) and smooth animations. It was found that extension mainly occurs in the radial-carpal joint and flexion is shared between the radialcarpal and midcarpal joints. During radial and ulnar deviation, the relative motion between the scaphoid and lunate was larger than in flexion-extension. this study will improve our understanding of carpal bone motion in a range of wrist poses, and will provide morphological data for the design of a functional wrist replacement arthroplasty. © Springer-Verlag Berlin Heidelberg 2004.

the bi-level programming of airport time slot allocation at a peak hour

international conference on Intelligent Transportation

作者： Sui-Ling Li Department of Shipping & Transportation Management National Penghu Institute of Technology Makung Taiwan

the allocation of airport time slot not only impacts the airlines' service level to passengers, but also influences airlines' profits of market share. therefore, this study attempts to present the optimal allocation aspects of airport time slot for the passengers and airlines and considers the constraints of airport capacity at peak hours. this study proposes the optimal time allocation model by the bi-level programming to analyze the airport time slot issues. One outcome shows that if passenger is the leader and airline the follower, then the time slot of offshore island routes should be more than other routes. the other outcome shows that if the airline is a leader and passenger the follower, then the time slot is prior to main-island route of longer distance. Both outcomes demonstrate that aviation is suitable to offshore island and long distance transportation.

Globally optimal solutions to the on-ramp metering problem - Part 1

international conference on Intelligent Transportation

作者： G. Gomes R. Horowitz Department of Mechanical Engineering University of California Berkeley USA

A mathematical programming approach to the freeway on-ramp metering problem is formulated. the objective function is a linear combination of mainline and on-ramp flows, termed the generalized total travel time. the underlying freeway model - the asymmetric cell transmission model (ACTM) - is similar to the original cell transmission model (CTM), except that the merge law of the CTM has been replaced with additional terms weighted by the influence parameters. It is shown that an appropriate selection of the model parameters and boundary conditions guarantees a physically reasonable evolution of the ACTM. It is also shown that the resulting nonlinear optimization problem can be solved globally, by solving an equivalent linear program, whenever the cost weights are generated by a proposed numerical algorithm.

7th Workshop on Languages, Compilers, and Run-Time Support for Scalable Systems, LCR '04

Networks of mobile devices and embedded systems represent a new computing platform. Typical network nodes range from sensors, cell phones, PDA's, to laptop computers. Wireless ad-hoc networks are used to connect these heterogeneous nodes, each of which has different capabilities and resources and may provide different services. Most applications targeting such networks will exploit the physical locations of the network nodes. SpatialViews is a language for applications executing on volatile networks of mobile devices and embedded systems. SpatialViews provides high- level abstractions for dynamic service discovery, location-awareness, and in-network aggregation. the compiler translates a SpatialViews program into low-level representations that use light-weight execution migration and property based routing. this paper investigates the impact of parallelization and replication on program performance metrics such as response time, energy consumption, and quality of result (QoR). For a simple application program running over networks with a range of different node failure rates, analytical modeling, simulation, and physical measurement revealed different energy/response time/QoR tradeoffs among different parallelization strategies and replication degrees.

Although cnidarian nervous systems appear to make heavy use of neuropeptides, evidence of the presence of biogenic amine transmitter systems has also surfaced over the past two decades. Our and other laboratories have used several analytical methods to reveal the presence of catecholamines and indoleamines in cnidarians, some of which are traceable to specific subsets of neurons. Evidence was also provided of amine biosynthesis, and of neuronal catecholamine release. Adrenergic-like and serotonin-like receptors were pharmacologically characterized by bioassays and by radiobinding assays in the sea pansy Renilla koellikeri, and these receptors appear to mediate activities such as bioluminescence and peristaltic contractions. the search for their structural identity has led to the molecular cloning and characterization the sea pansy of two new G protein-coupled receptors, Ren1 and Ren2, exhibiting homologies with aminergic receptors. In contrast to the receptors characterized in sea pansy membranes, none of the two cloned receptors responded to conventional amines when expressed in mammalian cell lines. Ren1 displayed constitutive cyclic AMP-generating activity when expressed in mammalian cells. these findings illustrate the challenges posed by attempting to reconcile physiological and molecular data in the quest for functional relevance of cnidarian transmitter systems.

Non-rigid image registration is widely used in the analysis of brain images to the extent it is provided as a standard tool in common packages such as SPM. However the performance of algorithms in specific applications remains hard to measure. In this paper a detailed comparison of the performance of an affine, B-Spline control-point and viscous fluid registration algorithm in inter-subject brain registration is presented. the comparison makes use of highly detailed expert manual labellings of a range of structures distributed in scale and in location in the brain. the overall performance is B-Spline, fluid, affine (best first) with all algorithms struggling to improve the match of smaller structures. We discuss caveats, evaluation strategies for registration and implications for future registration-based neuroimaging studies. © Springer-Verlag Berlin Heidelberg 2004.
