with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
the rise and stublishment of safavid dynasty was depend on triangle of tasavof, tashayo and royalty, kings legitimized their power upon these. therefore for the understanding the functions of that period we must explore the role of this elements. although application and emphsise upon dignities such as; complete mentor (morshede kamel), deputy of absent imam (nayebe imame ghayeb), and god’s sha...
* In my opinion the connection of fractional-level and supergroup Wess-ZuminoWitten models to string theory is remote. It is definitely not substantiated in any of the given references. Unless this connection can be described more concretely (a precise reference to a paper in which this is discussed would be enough), these models should rather be counted among those “studied for their own sake”.
The world is changing at an incredible pace. An enormous amount of data is being generated continuously everywhere at a rate faster than ever before, leaving us with the challenge of making sense out of it at the right time and the right place. With concepts such as the Internet of Things, CyberPhysical-Systems, Cooperating Objects and Smart Cities, things are only going to get worse. But are w...
Smart cities are a popular and recognized research topic. In urban spaces, the learning factor is an important component for citizens and local communities. This paper presents a systematic mapping of the literature on smart city learning, with focus on how technology is used to enhance smart city learning. The goal is to map the state of the art and to identify gaps in current research that ca...
Smart Grid is designed to integrate advanced communication/networking technologies into electrical power grids to make them ‘‘smarter’’. Current situation is that most of the blackouts and voltage sags could be prevented if we have better and faster communication devices and technologies for the electrical grid. In order to make the current electrical power grid a Smart Grid, the design and imp...
With the growing development of smart cities, public transit forecasting has begun to attract significant attention. In this paper, we propose an approach for forecasting passenger boarding choices and public transit passenger flow. Our prediction model is based on mining common user behaviors for semantic trajectories and enriching features using knowledge from geographic and weather data. All...
C-cross topologies are introduced. Modifications of the Kuratowski-Ulam Theorem are considered. Cardinal invariants add , cof, cov and non with respect to meager or nowhere dense subsets are compared. Remarks on invariants cof(nwdY ) are mentioned for dense subspaces Y ⊆ X.
