In this paper, welding of dissimilar metals was demonstrated for the first time, to the best of our knowledge, by using a high-energy high-repetition-rate femtosecond fiber laser. Metallurgical and mechanical properties were investigated and analyzed under various processing parameters (pulse energy, repetition rate, and welding speed). Results showed that the formation of intermetallic brittle...

The purpose of the dissimilar paths problem is to find a set paths, between same pair nodes, which share few arcs. has been addressed from an application point view, and integer programming formulations have also introduced recently. In present work, it assumed that each arc assigned with cost, goal then while simultaneously minimizing total cost. Some previous formulations: one number repeated...

In short-term serial recall, similar-sounding items are remembered more poorly than items that do not sound alike. When lists mix similar and dissimilar items, performance on the dissimilar items is of considerable theoretical interest. S. Farrell and S. Lewandowsky (2003) recently showed that if guessing strategies are controlled, dissimilar items on mixed lists are recalled more accurately th...

Let be a nite alphabet and x 2 n. A string y 2 m is said to be k-dissimilar to x, if no k length substring of x is equal to any k length substring of y. We present an O(n log n) algorithm which on input x 2 n and an integer m n outputs an integer k and y 2 m such that: { y is k-dissimilar to x. { There does not exist a string z of length m which is k ? 1 dissimilar to x.

48 male and 48 female Ss took part in a study of "impression formation," during which they evaluated a "partner" who was presented as either similar or dissimilar to themselves, and who was further presented as either normal or emotionally disturbed. Ss rated the partner's attractiveness, similarity to themselves, and indicated their willingness to interact with him. When the partner was believ...

This paper contains a theoretical formulation of multiple interface cracks in two bonded dissimilar half planes subjected to in-plane traction. The distributed dislocation technique is used to construct integral equations for a dissimilar mediums weakened by several interface cracks. These equations are of Cauchy singular type at the location of dislocation, which are solved numerically to obta...

In this work, we show that identical TiO2-based memristive devices that possess the same initial resistive states are only phenomenologically similar as their internal structures may vary significantly, which could render quite dissimilar switching dynamics. We experimentally demonstrated that the resistive switching of practical devices with similar initial states could occur at different prog...
