An ultra-wide band band-pass filter using novel spiral stub-loaded triple-mode resonator (SSLTMR) is presented. New spiral stub loaded resonator is analyzed with odd and even modes analysis for this class of BPF, achieving higher band wide and size reduction. In order to have a good response characterized, two (SSL-TMRs) and two quarter wavelength digital coupled lines are used. This new design...

Abstract This paper develops a novel design methodology for the off-grid PV system by applying demand- side management (DSM) approach. DSM strategy is used optimal distribution of electrical energy among load. Various types load are being categorized based on priority. In case power shortage, top-priority will get more reliable supply. Moreover, shortage distributed loads. A programming model h...

Background: There are few psychometric studies addressing sensitivity and specificity of the Persian version of the Edinburgh Postnatal Depression Scale (EPDS). Therefore, there is a need for future studies to identify the best cut-off point for EPDS score. The present study is aimed at assessing the validity of the EPDS among Iranian mothers. Materia...

This paper investigates the off-line use of the dependency structure matrix genetic algorithm (DSMGA). In particular, a problemspecific crossover operator is design by performing dependency structure matrix (DSM) analysis. The advantages and disadvantages of such an off-line use are discussed. Two schemes that helps the off-line usage are proposed. Finally, those off-line schemes are demonstrat...

determination of trade-off, which they are feasible and similar variations on all of decision making units (dmu), is important issue in data envelopment analysis (dea). in this paper, we select these trade-offs based on an external evaluation of dmus such that the correlation between external evaluation and technical evaluation resulted from dea model is maximized. in fact, we sift the trade-of...

the industrial design is a two or three-dimensional aesthetic creation related to industrial products. according to the definition of the iranian law, for the realization of the legal protection of industrial designs there are three necessary components: combine lines or colors, runs on industrial products and change product appearance. in iran, only the registered designs are supported. while ...

Abstract The dual carbon target in China, which is set to improve the low and economy of regional microgrid (villages northwest China for example) energy consumption, proposed use compressed air storage utilization rate distributed new reduce cost power purchase upper grid. Therefore, system dynamic characteristics simulation performance analysis under wide working conditions are very important...

The wings of the aircraft reflect an aircraft's primary lift unit. aerodynamic strain, weather, wind and vibration are liability wing throughout ride. Aeronautical structural stresses may often be handled by wings. Therefore, must constructed to have good overall efficiency each period operation, both structurally aerodynamically. Spar, ribs, thongs skin main elements a construction. It is flut...
