The multiple-block divider is to obtain the broad-band and high frequency operation in phase-locked loop (PLL). ILFD has a similar structure with LC cross-coupled oscillator which operates at 20 GHz. 3 stages of ILFD are supposed to provide the operation of divide-by-8 (/8) with low power consumption and are to adjust the frequency alignment with the LC cross-coupled oscillator. CML frequency divider which is used as the 2nd block of divider applies an inductive peaking structure in order to increase the bandwidth. The proposed frequency divider which has the /8 ILFD and /32 CML frequency divider is integrated with 0.18 μm CMOS process and operates in the conventional PLL. Simulation test shows the low power consumption of 13.2 mW at the input frequency of 20 GHz.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125111715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main non-linear factor leading to the PIO is, generally, rate limitations of the aircraft control surfaces, resulting in a delay in the response of the aircraft to pilot commands. Due to the tight relationship between magnitude and phase frequency responses for linear systems, applicability of the linear compensator for mentioned aim is highly restricted. This leads to the idea of employing the nonlinear phase shift compensator. In the control theoretic literature, various nonlinear corrective devices (NCD) are elaborated, which make it possible to change the phase-frequency and amplitude-frequency responses independently on each other. In the paper, a novel phase shift compensator based on nonlinear correction technique is presented and numerical comparative study for two models of a pilot for PIO prevention during the flight is given. The results obtained demonstrate that the proposed method in several times increases the admissible gain of the \"airplane-pilot\" loop as compared with non-corrected system.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126401754","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicate that a saving of 65% -- 99% in the invoicing time can be achieved when using an electronic waybill instead of paper waybills.

The adaptive filter used has an additional penalty term to promote sparsity in the estimation of the convolution kernel. From the derived convolution kernel an estimate of the displacement field is made, from which an interpolated image is generated. This estimate can then be refined by iterating over the filtering process using the image generated as the new target image. Stability in the refining iterations is improved by using multiple space filling curves for the adaptive filter scan paths. This not only smoothes the changes in the displacement vectors but the multiple paths add diversity, which improves the evolution of the adaptive filter through more difficult portions of the image content. Due to this greater stability, the forgetting factor for the adaptive filter can be reduced allowing more detail in the displacement to be determined. The resultant system compares favourably with a standard intensity based image registration technique with the commercial Mat lab implementation. A selected set of tests were also performed with the Middlebury dataset [1], which shows the comparative strength and weaknesses of the approach.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127615589","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has emerged as an attractive research problem due to possessing several desirable merits unlike other biometrics. However, most of the existing gait recognition methods that involve Gabor-based filters suffer from the curse of dimensionality, even with the use of a dimensionality reduction technique. This adds more computational and storage burdens and may cause difficulties to identify subjects with a high degree of confidence. In this paper a statistical gait recognition approach is proposed based on the analysis of overlapping Gabor-based regions. The Gait Energy Image (GEI) is first constructed from the gait sequence as a spatio-temporal summary. Then, the GEI image is convolved with a Gabor filter bank of 8 different orientations and 5 different scales. A statistical analysis is then applied to extract discriminative gait features from multi-overlapped Gabor-based regions. Consecutively, an SVM classifier is applied to measure the gait similarity and identify the subject. Comprehensive experiments are carried out to evaluate the proposed approach and compare it to existing approaches. The results have shown that promising performance can be achieved with the proposed approach under a variety of scenarios.","PeriodicalId":253479,"journal":{"name":"2015 IEEE European Modelling Symposium (EMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131238675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The level of packet reordering, however, becomes higher: distant packets are reordered, the application performance is reduced due to head-of-line blocking at the destination, and a large resequencing buffer is needed for sorting incoming packets. In this paper, we study the stochastic compensation effect to reduce packet reordering. If a source randomizes packet scheduling into multiple paths of random transmission delays, then these two sides of randomness \"quench\" each other. We perform simulation experiments to test this hypothesis in various multipath configurations and compare deterministic vs. Randomized scheduling.
