The important feature of the calculation of such structures for microwaves is the necessity of taking into account wave properties of piezoelectric films and electrodes because their thickness is comparable with wavelength in the material.","PeriodicalId":380710,"journal":{"name":"2006 Multiconference on Electronics and Photonics","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124913540","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}

Applied software provides reading and processing the TIE and decodes the negative sawtooth from the GPS timing receiver.

It allows one to calculate the optical transmission in the transducer as a function of the refractive index of the surrounding medium. The software allows one to analyze the detection elements having a smooth working surface of the second order of any of the following shapes: a segment of a sphere, ellipsoid, and paraboloid. Our results generalize previous work [1], [2] where the element geometry was a hemisphere.

The results extend our first studies and we show how the ratio of radii and direction of main curvature of a piezoelectric plate surface both affect the frequency shifts and amplitude distributions. We notice that the direction of the main curvature causes a substantial influence upon localization of self-vibrations. The dependence in this case is closer to the linear one, although it still needs more profound investigations for the surfaces with different geometries.","PeriodicalId":380710,"journal":{"name":"2006 Multiconference on Electronics and Photonics","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128805851","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}

Both are artificial intelligence processes for tackling real-world problems. Planning studies action-selection for obtaining good quality plans. On the other hand, scheduling studies the suitable resources application in any plan. However, when the AI planning community has tried to solve real-world problems, they have seen the necessity to combine both planning and scheduling techniques. Additionally, in the state-of-the-art, there are two approaches to solve these problems: extended planning and extended scheduling. The first approach results in a high computational complexity, and the second approach uses a rigid plan template (embedded planner) avoiding the possibility of re-planning. Otherwise, our system homogeneously solves resources conflicts, in a flexible design with a strongly coupled form. Consequently, this model promises to be efficiently enough to obtain executable and consistent plans.","PeriodicalId":380710,"journal":{"name":"2006 Multiconference on Electronics and Photonics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127996489","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}
