This paper studies a general inverse eigenvalue problem which generalizes many well-studied pole placement and matrix extension problems. It is shown that the problem corresponds geometrically to a so-called central projection from some projective variety. The degree of this variety represents the number of solutions the inverse problem has in the critical dimension. We are able to compute this...

Integrated test technology is becoming critically important for MEMS due to the high reliability and safety critical applications targeted. High quality levels in production require efficient test strategies that are properly validated. Fault simulation and testability analysis are critical utilities required to support this process. This paper will discuss methods for achieving test support ba...

Given two Jordan curves in a Riemannian manifold, a minimal surface of annulus type bounded by these curves is described as the harmonic extension of a critical point of some functional (the Dirichlet integral) in a certain space of boundary parametrizations. The H2,2regularity of the minimal surface of annulus type will be proved by applying the critical points theory and Morrey’s growth condi...

Abst rac t . AORTA has been proposed as an implementable real-time algebra for concurrent systems where event times, rather than values of data, are critical. In this paper we discuss an extension to AORTA to include a formal data model, allowing integration with a variety of modelbased data specification languages. An example is given using VDM with AORTA to define a time-critical system with ...

Lack of understanding of the extension, education, and development practitioners’ role and their contribution to sustainable agriculture is the main challenge of sustainability projects in Iran. Accordingly, the aim of this study was toidentify the extension system that has been more successful in sustainable horticulture. The population consisted of 22 pioneer farmers that had used or are usin...

The study was carried out to assess the implication of the use of selected Information and Communication Technologies (ICTs) for extension service delivery in Nigeria. The simple random technique was used to select fifty percent of the total extension agents which equivalent to forty-two respondents as sample size for the study. Frequency counts, percentages, mean and standard deviation were us...

AbstractThe purpose of this study was to assess organizational and personnel structure in Iranian Agriculture Extension System (IAES). The research instrument was a structural questionnaire including close-ended questions which its validity and reliability was confirmed by using expert panel and Cranach’s alpha test, respectively. The statistical population of this research included all public ...

Agricultural extension, as an informal educational system, is one of agricultural development tools that lean on human capitals. Inefficiency of public bureaucracy on the one hand, and managerial problems on the other hand, as well as neglecting real needs of beneficiaries in planning, have determined responsible to transfer administrative tasks to the private sector and reduce government''s te...
