This paper discusses the Finite Element analysis (FE) conducted to predict behavior of Glass Fiber Reinforced Concrete (GFRC) beams without shear reinforcement (stirrups) and strengthen them with proposed techniques increase their strength. for this study, A total eighteen (18) (120 * 300 2200 mm) specimens were modeled using Ansys™ mechanical. The main variables percentage discrete glass fiber...

In genomic signal processing applications, digitization of these signals is needed to process and analyze DNA signals. the process, mapping technique be chosen greatly affects performance system for domain studied. The purpose this review how numerical techniques used in digitizing sequences affect studies. For purpose, all digital coding presented literature studies conducted last 10 years hav...

This paper gives an overview of the difficulties associated with the design of hard rock pillars in South African mines. Recent examples of large scale pillar collapses in South Africa suggest that these were caused by weak partings which traversed the pillars. Currently two different methods are used to determine the strength of pillars, namely, empirical equations derived from back analyses o...

We give further results for Perron-Frobenius theory on the numericalrange of real matrices and some other results generalized from nonnegative matricesto real matrices. We indicate two techniques for establishing the main theorem ofPerron and Frobenius on the numerical range. In the rst method, we use acorresponding version of Wielandt's lemma. The second technique involves graphtheory.
