The Research-Engaged School: The Development and Test of a Causal Model through an Exploratory Mixed Methods Design

The Research-Engaged School: The Development and Test of a Causal Model through an Exploratory Mixed Methods Design   Sh. HosseinPour, Ph.D.[1] H.R. Zeinabadi, Ph.D. [2]   The present study was undertaken to design and test a research-engaged school model using mixed methods design. In the qualitative and quantitative parts of the study, phenomenological strategy and structural equation mod...

Compact and Efficient Active Vibro-acoustic Control of a Smart Plate Structure

An effective wide band active control law through one kind of the Dynamic Vibration Absorber (DVA) is proposed and studied in this paper. With the help of mechanical impedance method, active DVA control law is formulated based on the passive mechanical model. The electrical DVA can generate multi-mode active damping to the structure. The host structure is an aluminum plate and acceleration sign...

Changing Regional Spatial Structure of the Population and Activity The Case of West Azerbaijan Province, Iran

Functional and structural changes of regional system are ongoing spatial changes that form patterns of spatial organization, depending on dominant regional forces and factors. Spatial structure of West Azerbaijan province experienced significant changes during 15 years; thus, the present research aim to investigate the manner of spatial distribution of two variables of population and activity, ...

SEISMIC BEHAVIOR OF SILOS WITH DIFFERENT HEIGHT TO DIAMETER RATIOS CONSIDERING GRANULAR MATERIAL-STRUCTURE INTERACTION

Silos are structures that are used for storing different types of granular material. Dynamic behavior of silos under seismic loads is very complex. In this paper seismic behavior of steel silos with different height to diameter ratios is investigated by considering granular material-structure interaction using ABAQUS finite element package. Silo wall is modeled by shell elements and its behavio...
