This paper investigate the impact of packet size on the performance of 802.15.4 for Wireless Sensor Network based on various packet size scenario like packet size 300, 600 and 900.The comparative results have been reported for the performance metrics like Battery energy consumed, Traffic sink end to end delay and Traffic received. Packet size optimization is an important issue in energy constra...

Stevens Institute of Technology Hoboken, NJ, USA {hwang,[email protected]} Abstract. We study the privacy threat by publishing data that contains full functional dependencies (FFDs). We show that the cross-attribute correlations by FFDs can bring potential vulnerability to privacy. Unfortunately, none of the existing anonymization principles can effectively prevent against the FFD-based priv...

exp(2 i( p 1 i ) are the eigenvalues of the Milnor monodromy and their integral part is determined by the Hodge ltration of the mixed Hodge structure. This notion was rst introduced by Steenbrink [11]. By [14] the exponents are constant under -constant deformation of f . In particular, they depend only on f 1 (0). They express the vanishing order (up to the shift by one) of the period integrals...

Feature Diagrams (FDs) are a family of popular modelling languages, mainly used for engineering requirements in software product lines. FDs were first introduced by Kang et al. as part of the FODA (Feature Oriented Domain Analysis) method back in 1990. Since then, various extensions of FODA FD were devised to compensate for purported ambiguity and lack of precision and expressiveness. Recently,...

Severe plastic deformation is a technical method to produce functional material with special properties such as high strength and specific physical properties. Selection of an efficient severe plastic deformation for grain refinement is a challenging field of study and using a modeling technique to predict the refinement efficiency has gained a lot of attentions. A comparative study was carried...

Abstract: Noise filtering, data predicting, and unmonitored data interpolating are important to dam deformation data analysis. However, traditional methods generally process single point monitoring data separately, without considering the spatial correlation between points. In this paper, the Space-Time Kalman Filter (STKF), a dynamic spatio-temporal filtering model, is used as a spatio-tempora...

Resolution degradation due to gradient coil deformation and vibration in NMR microscopy is investigated using finite element analysis. From the analysis, deformations due to the Lorentz force can be as large as 1-10 mum depending on the gradient strength and coil frame material. Thus, these deformations can be one of the major resolution limiting factors in NMR microscopy. Coil vibration, which...

[1] InSAR time series analysis is an effective tool for detecting spatially and temporally complicated volcanic deformation. To obtain details of such deformation, we developed an advanced InSAR time series analysis using interferograms of multiple-orbit tracks. Considering only right(or only left-) looking SAR observations, incidence directions for different orbit tracks are mostly included in...

AIMS Different layers of myocardium may contribute differently to myocardial deformation. Speckle tracking based on high resolution two-dimensional (2D) echocardiography has been used to define myocardial deformation parameters of whole left ventricular (LV) segments. This study evaluated with a Novell analysis modality allowing layer-specific analysis of deformation if there are differences in...
