The coupling of simultaneous switching noise (SSM) in mixed signal system on package modules is a critical signal and power integrity (SI/PI) problem. In the presence of split planes and apertures, SSN coupling occurs both horizontally as well as vertically across layers. Thus, to catch SI and PI problems at an early stage of design requires fast signal and power co-simulation methodologies. In this paper, we outline the multi-layer finite difference method and how the accuracy of the technique can be enhanced with models for fringe and gap effects. We then briefly describe a method for integrating the signal distribution network with the power distribution network to enable co-simulation. The method is then applied to a mixed signal board containing split planes, and numerical results are compared to full-wave simulations. © 2007 IEEE.

Finding an accurate network null model for protein-protein interactions (PPI) networks is an important and fundamental problem in today's systems biology. A number of graph models were introduced to model and analyze PPI networks. However, because the previous network models were developed to capture specific network properties or just mimic the way that real PPI network might have evolved, the whole connectivity information of PPI networks is not utilized to learn the topological structure of the networks. In this paper we propose a novel model for PPI networks which is based on geometric random graphs and employs the entire connectivity information of PPI networks to learn its structure. The computational experiments show the superiority of the fit of our method over five other network models to PPI data. Thus, the proposed network null model could facilitate further graph-based studies of protein-protein interactions and may help infer their hidden underlying biological knowledge. © 2012 Springer-Verlag.

Cross-Domain Few-Shot Relation Extraction via Representation Learning and Domain Adaptation

Few-shot relation extraction aims to recognize novel relations with few labeled sentences in each relation. Previous metric-based few-shot relation extraction algorithms identify relationships by comparing the prototypes generated by the few labeled sentences embedding with the embeddings of the query sentences using a trained metric function. However, as these domains always have considerable differences from those in the training dataset, the generalization ability of these approaches on unseen relations in many domains is limited. Since the prototype is necessary for obtaining relationships between entities in the latent space, we suggest learning more interpretable and efficient prototypes from prior knowledge and the intrinsic semantics of relations to extract new relations in various domains more effectively. By exploring the relationships between relations using prior information, we effectively improve the prototype representation of relations. By using contrastive learning to make the classification margins between sentence embedding more distinct, the prototype’s geometric interpretability is enhanced. Additionally, utilizing a transfer learning approach for the cross-domain problem allows the generation process of the prototype to account for the gap between other domains, making the prototype more robust and enabling the better extraction of associations across multiple domains. The experiment results on the benchmark FewRel dataset demonstrate the advantages of the suggested method over some state-of-the-art approaches. © 2022, CC BY-NC-SA.

Packet propagation delay reduction is becoming the primary concern of the Internet. Internet service providers (ISPs) attempt to optimize packet routing to offer the best route to their subscribers by achieving desired network performance. Consequently, a route computation metric that uses packet propagation delay instead of link state will be a strong incentive for ISP routing optimization, in which case ISPs could ensure minimal delay route paths for their subscribers. To this end, we present SLRouting, a novel Interior Gateway Routing Protocol. SLRouting calculates a composite route metric using packet waiting delays of servers and routers as well as the packet propagation delay of network links. SLRouting computes the route matrix by selecting the minimal delay path for destination networks. This paper presents the first version of the SLRouting including its theory, design, and implementation notes. A prototype of the proposed protocol is implemented using the ns-3 simulator, and the results were used to evaluate the proposed protocol. © 2015 ACM.

Evaluation of Mouse and Touch Input for a Tabletop Display Using Fitts' Reciprocal Tapping Task

引用

Proceedings of the Human Factors and Ergonomics Society Annual Meeting 2009年第12期53卷 839 - 843页

作者： Farzan Sasangohar I. Scott MacKenzie Stacey D. Scott Dept. of System Design Engineering University of Waterloo Dept. of Computer Science and Engineering York University

User performance with a tabletop display was tested using touch-based and mouse-based interaction in a traditional pointing task. Dependent variables were throughput, error rate, and movement time. In a study with 12 participants, touch had a higher throughput with average of 5.53 bps compared to 3.83 bps for the mouse. Touch also had a lower movement time on average, with block means ranging from 403 ms to 1051 ms vs. 607 ms to 1323 ms with the mouse. Error rates were lower for the mouse at 2.1%, compared to 9.8% for touch. The high error rates using touch were attributed to problems in selecting small targets with the finger. It is argued that, overall, touch input is a preferred and efficient input technique for tabletop displays, but that more research is needed to improve touch selection of small targets.

The non-idealities of full-duplex devices of the transceiver chain is not well known despite of the intensive recent research on wireless single-channel full-duplex communications. However, in spite of the use of efficient analog and digital cancellation and suitable physical antenna isolation they turn out to be among main practical reasons for observing residual self-interference. In this paper the implementation and simulation of RF transceiver Duplex Filter and noise isolation improvement using Matlab/SIMULINK environment is done, as well as quantifying the dynamic range of required signal and the reduction of these IF-interference due to the analog-to-digital interface. The Transfer Function calculation results are provided by the help of a White Noise Source and Simulation results of frequency response in the Tx and Rx channels. The simulation and measurement results comparison for new duplexer and the marks and values of frequency response at the critical frequency points have improved isolation due to the effect of optimized external inductor. It has been observed in a full-duplex transceiver that the transmitter power amplifier (PA) produces a nonlinear distortion that is considered to be a significant issue. © 2020 IEEE.

The radar is considered as one of tracking application which we need to tracking unknown targets. This application is using a kalman filter. Also the extended and unscented kalman filter has been created to deal with nonlinear systems such as multidimensional radar tracking. If wideband radar is used, multiple return signals may be obtained by scattering on a single target in a single pulse. It is important to monitor multiple dispersions on an undefined number of artifacts in the specific problem considered, with a standard wideband radar model, whose motion involves a nonlinear rotational velocity component. The measurements used are scattered range, range-rate (in analogy to Doppler), nonlinear functions of the scattered position and velocity, with parameters in the state-space model. In order to evaluate the scene and observe its progression over time, the tracker design uses a Kalman Filter type to model the nonlinear dynamics and measurement items and a multi-pronged association scheme. © 2022 IEEE.

Lab report writing (and teaching!) made easy

Lab report writing (and teaching!) made easy

2008 ASEE Annual Conference and Exposition

This paper reports on a project to improve students' ability to write better lab reports and assist teaching assistants (TAs) in grading reports in a consistent manner. A lab report teaching system was developed that includes lab report templates, teaching assistant instructions, grading rubrics, examples, peer review materials and instructions, and recommendations for quickly providing student feedback (grading). These materials were developed for project-based labs across the electrical engineering curriculum and utilize methods to write weekly lab updates that are combined into a final lab report, mimicking methods commonly used in industry. The technical writing information was adapted to all levels of complexity to help students from freshman through senior years. The system begins with instruction on writing very basic reports, and builds each year on previous knowledge and practices, to prepare students to later write complex reports. This system is designed to improve students' understanding of labs (by 'writing to learn') in addition to preparing them for the communication intensive workplace. The amount of time spent grading such reports is often a primary concern, as this is commonly given as a reason for not requiring advanced writing assignments in engineering classes. Detailed guidelines and grading rubrics are included in this manual to instruct TAs on better and more consistent grading techniques. Guidelines for checking both lab books and formal lab reports help improve TA training and grading consistency, reducing student complaints. Although this system was designed for an electrical engineering program, it can also be adapted to other technical fields and used for various scientific lab reports. © American Society for engineering Education, 2008.
