Displacement-based methods are recognized as appropriate approaches to reach the goals of performance-based seismic design method. In the direct displacement-based seismic design method, the seismic yield displacement is applied as one of the important design parameters. In this paper, a new relation is suggested to determine the lateral displacement pattern at first yielding of eccentrically b...

The present study examines how Trump’s unilateral withdrawal from the Joint Comprehensive Plan of Action (JCPOA) on May 8, 2018 was framed in political cartoons published in the American and French media. The paper offers a thematic analysis of cartoons published from May 8 to June 8, 2018, the peak period for publication of cartoons on the Iran nuclear deal, and accessed via Google images. The...

dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

We propose a digital image stabilization algorithm based on improved SageHusa filter. Global motion estimation is obtained by detecting interest points from reference frame, matching points in current frame, and solving motion equations. The motion includes intentional camera scan and unwanted jitter; therefore, we need to smooth global motion sequence to remove jitter. The Sage-Husa filter is ...

Many applications in biology, such as long-term functional imaging of neural and cardiac systems, require continuous high-speed imaging. This is typically not possible, however, using commercially available systems. The frame rate and the recording time of high-speed cameras are limited by the digitization rate and the capacity of on-camera memory. Further restrictions are often imposed by the ...

We present a workbench for the study of real-time quantum imaging by measuring the frame-by-frame quantum noise reduction of multi-spatial-mode twin beams generated by four wave mixing in Rb vapor. Exploiting the multiple spatial modes of this squeezed light source, we utilize spatial light modulators to selectively pass macropixels of quantum correlated modes from each of the twin beams to a h...

We present an implementation of Simultaneous Localization and Mapping (SLAM) that uses infrared (IR) camera images collected at 10 Hz from a Packbot robot. The Packbot has a number of challenging characteristics with regard to vision based SLAM. The robot travels on tracks which causes the odometry to be poor especially while turning. The IMU is of relatively low quality as well making the drif...

A system for dynamic mapping of broadband ultrasound fields has been designed, with high frame rate photoacoustic imaging in mind. A Fabry-Pérot interferometric ultrasound sensor was interrogated using a coherent light single-pixel camera. Scrambled Hadamard measurement patterns were used to sample the acoustic field at the sensor, and either a fast Hadamard transform or a compressed sensing re...
