fUser Behavior and IM Topology Analysis
نویسندگان
چکیده
The use of Instant Messaging, or IM, has become widely adopted in private and corporate communication. They can provide instant, multi-directed and multi-types of communications which make the message spreading in IM different from those in WWW, Blog and email systems. Groups have great impacts on message spreading in IM. The research demonstrates the power law distribution of groups in MSN with parameterγ ranging from 0.76 to 1.22. Based on an online survey, IM user behavior is analyzed from the aspects of message sending/receiving and contacts maintaining. According to the results, degree distribution of users has a peak value and doesn't present power law character. This may indicate that social networks should be a prospective direction for the research on IM topology.

On Optimal Projective Fusers For Function Estimators
We propose a fuser that projects diier-ent function estimators in diierent regions of the input space based on the lower envelope of the error curves of the individual estimators. This fuser is shown to be optimal among projective fusers and also to perform at least as well as the best individual estimator. By incorporating an optimal linear fuser as another estimator, this fuser performs at le...
متن کاملExperiments on Individual Classifiers and on Fusion of a Set of Classifiers
In the last decades many classification methods and fusers have been developed. Considerable gains have been achieved in the classification performance by fusing and combining different classifiers. We experiment a new method for ship infrared imagery recognition based on the fusion of individual results in order to obtain a more reliable decision [1]. To optimize the results of every class of ...
متن کاملLow Energy Printing: an Exploration in Cold Pressure Fusing
1. ABSTRACT The primary goal of this Senior Design project is to examine a low energy, non-thermal fuser that is capable of fusing toner to paper without the use of heat. This fuser will use pressure only and be able to be retrofitted to existing printers to be used in locations where power supply is limited. Two fuser assemblies will be constructed for evaluation. The first design will be a fo...
متن کاملTOPOLOGY OPTIMIZATION OF PERFORATED STEEL PLATE SHEAR WALLS WITH THICK PLATE IN SIMPLE FRAMES
In this paper, topology optimization (TO) is applied to determine the form, size and location of holes for the special form of perforated steel plate shear wall (PSPSW). The proposed model is based on the recently presented particular form of PSPSW that is called the ring-shaped steel plate shear wall. The strain energy is selected as the objective function in the optimization. Simple Isotropic...
متن کاملSpeaker Tracking Using Particle Filter Sensor Fusion
in Proc. of Asian Conference on Computer Vision (ACCV), 2004 Sensor fusion for object tracking has become an active research direction during the past few years. But how to do it in a robust and principled way is still an open problem. In this paper, we propose a new fusion framework that combines both the bottom-up and top-down approaches to probabilistically fuse multiple sensing modalities. ...
