an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

We consider the problem of testing for the presence (or detection) of an unknown sparse signal in additive white noise. Given a fixed measurement budget, much smaller than the dimension of the signal, we consider the general problem of designing compressive measurements to maximize the measurement signal-to-noise ratio (SNR), as increasing SNR improves the detection performance in a large class...

It is known that it a very restrictive condition for frame $\{f_{k}\}^{\infty }_{k=1}$ to have representation $ \{T^n \varphi \}_{n=0}^\infty as the orbit of bounded operator $T$ under single generator $\varphi \in \mathcal H.$ We prove that,

In this paper, a novel procedure is presented for segmenting a general 3-D wireframe model obtained from a head and shoulders multiview sequence. The procedure consists of two steps. In the rst step, two ellipses corresponding to the head and the body of the person are identi ed based on ellipse tting of the outline of the person in each image. The tting is based on a direct least squares metho...

The aim of this paper is to provide a design guide of the LRFD based advanced analysis method for practical frame design. To this end, the step-by-step analysis and design procedures for the practical advanced analysis method are presented. The proposed advanced analysis program and input data format are discussed. Case studies are drawn to show the detailed design procedures of the practical a...

With the large amounts of video data available, it has become increasingly important to have the ability to quickly search through and browse through these videos. The key frame extraction is an essential technology of video retrieval and has a great impact on retrieval efficiency by reducing the redundant information. In this paper we analyses the performance of simple Edge Change Ratio (ECR) ...

We have recently developed a hierarchical K-Means clustering method for weather images. Using this technique, it is possible to identify storms at different scales. In this paper, we will describe an error-minimization technique to identify movement between successive frames of a sequence and show that we can use the K-Means clusters as the minimization kernel. Using this technique in combinati...
