The approach is an extension of a previous authors work and is based on a parallel decomposition of the modulator. In this representation, the general N-th order modulator is transformed into a decomposition of low order, generally complex modulators, which interact only through the quantizer function. The decomposition considered helps for easy description of the time-domain behavior of the modulator. Based on this in the previous authors work, the conditions for the existence of limit cycles in the high order modulator, for constant inputs are obtained. They are determined by the periodicity conditions for the states of the first order modulators. In this case, the state variables are uncoupled and the obtained conditions are very easy to be checked. Limit cycles correspond to periodic output sequences and in the previous work the validation conditions are also proposed by the author. Here these conditions are considered in details. They help to search the possible limit cycles with different lengths.","PeriodicalId":117809,"journal":{"name":"Proceedings of the Joint INDS'11 & ISTET'11","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124880402","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 numerical algorithm for the electric field intensity computation takes into account a short power line and approximates the conductor charge density by a constant. The numerical algorithm for magnetic flux density computation is based on the application of the Biot-Savart law. The computed results are compared to measurements taken underneath a 400 kV power line. The computed results and measurements prove to be in good agreements keeping in mind that the sag of the power line section is approximated with a horizontal straight line. Both the computed results as well as measurements confirm the fact that the electric and magnetic fields of high voltage power lines are well within the prescribed limits.","PeriodicalId":117809,"journal":{"name":"Proceedings of the Joint INDS'11 & ISTET'11","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133281049","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}

We implement a self-adaptive mechanism that drives the local systems to share a common set of parameters Λ<inf>c</inf>. This situation therefore strongly differs from classical synchronization problems where the Λ<inf>k</inf> are kept constant. The deformations of the Λ<inf>k</inf> towards the consensual Λ<inf>c</inf> are “plastic” — once Λ<inf>c</inf> is reached, it remains permanent even in absence of interactions. Again, this has to be contrasted with classical synchronization which does not affect the Λ<inf>k</inf> (in the absence of interactions, individual behaviors are restored). The resulting consensual Λ<inf>c</inf> can be analytically characterized. In general, the set of initial conditions from which Λ<inf>c</inf> is reached depends on the network topology. The class of models discussed here unveil the basic features necessary to construct a wider class of dynamical system sharing self-adaptive attractor-shaping capability. Finally, we present numerical simulations that corroborate our theoretical assertions.","PeriodicalId":117809,"journal":{"name":"Proceedings of the Joint INDS'11 & ISTET'11","volume":"487 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123060204","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}

In this paper a detailed analysis and comparison of the existing methods, describing the behavior of a considered electrostatic field, is made. Two models, based on the pan filled with electrolyte and on the electrical-conductivity paper, respectively, are proposed and realized experimentally.

In many cases they are regarded as identical which leads to confusion with understanding of the fundamental concept of electromagnetic field. Related to this topic, some authors in their books and papers on electromagnetic theory have discussed what the voltmeter actually measures, which is resolved here in a simple way. In this paper it is shown that there is a difference between the terms voltage and potential difference depending on what is the observation point — static fields or time-varying fields. Also in the transmission line model, the voltage between two points depends on the path of integration and, therefore, is ambiguous. What is commonly referred to as voltage, is transversal voltage that is a special case of voltage equal to the potential difference that is unique. Similarly, in electrical circuit analysis, branch voltages are unique and equal to difference of nodal voltages (nodal potentials).","PeriodicalId":117809,"journal":{"name":"Proceedings of the Joint INDS'11 & ISTET'11","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130807697","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 utilization of the MNA approach ensures a high universality and covers arbitrarily complex systems on principle. The solution of resultant MNA differential algebraic equations (DAE) is based on the backward Euler method.
