Two vector direc- tional distance (VDDF) filters and one center weighted vector directional distance filter (CWVDDF) are proposed to be used in the first stage due to their desirable properties, such as, noise attenuation, chromaticity retention, and edges and details preservation. keywords: color; distance; filters; function; image; noise; output; processing; results; vddrhf; vector; vol cache: tjer-9.pdf plain text: tjer-9.txt item: #240 of 246 id: tjer-91 author: Singh, L.; Khan, R.A.; Aggarwal, M.L. title: Influence of Residual Stress on Fatigue Design of AISI 304 Stainless Steel date: 2011-06-01 words: 3174 flesch: 61 summary: It may be noticed that the depth of deformed layer is found to vary with shot peening intensity. Hence, it is not neces- sary that increase in shot peening intensity will always increase fatigue strength (Goa et al. 2003). keywords: fatigue; peening; shot; steel; stress; surface; vol cache: tjer-91.pdf plain text: tjer-91.txt item: #241 of 246 id: tjer-93 author: Siddiqui, N.

No. 1 (2011) 61-73 desired reliability of 3.2 ( T = 3.2), the concrete thick- ness should not be less than 3.0 m. As increasing the thickness of concrete barrier is quite an expensive option, it is better to also consider other parameters along with the thickness to reach the desired reliabili- ty. keywords: barrier; concrete; engineering; missile; penetration; reliability; soil cache: tjer-93.pdf plain text: tjer-93.txt item: #242 of 246 id: tjer-94 author: Nadir, Z.; Touati, F. title: Class-E Amplifier Design Improvements for GSM Frequencies date: 2011-06-01 words: 2607 flesch: 61 summary: Basic circuit of class E power amplifier 76 The Journal of Engineering Research Vol 8 No. 1 (2011) 74-82 (1) RL should be down-converted from 50 to 36.06 using a matching network as shown in Fig. 3 for optimum power delivery.

Smida, H. Lamloumi, Z. Hafsia and K. Maalel The problem of head-on collision of two solitary waves takes its origin from the study of the run-up of these waves on a vertical wall (tsunami case). Numerical results given by Power et al.

The mesh of bonded model is straight forward and simpler because of the absence of spot welding, which leads to only the overlap area that needs to be divided into fine mesh. keywords: adhesive; bonded; displacement; load; model; spot; thickness; weld cache: tjer-99.pdf plain text: tjer-99.txt
