The objective of the study is to investigate influence Polyethylene Terephthalate (PET) recycled plastic bottle fibers on compressive strength and cracking concrete. In this study, two types fiber are used: straight zigzag whose length aspect ratio 40 mm respectively. 0, 0.75, 1.25% volume fractions replacing coarse aggregates used in investigation. According ACI 211.1-91, design mixing 1:2:3 f...

This paper introduces a family of error-correcting codes called zigzag codes. A zigzag code is described by a highly structured zigzag graph. Due to the structural properties of the graph, very low-complexity soft-in/soft-out decoding rules can be implemented. We present a decoding rule, based on the Max-Log-APP (MLA) formulation, which requires a total of only 20 addition-equivalent operations...

We describe a new methodology for studying persistence of topological features across a family of spaces or point-cloud data sets, called zigzag persistence. Building on classical results about quiver representations, zigzag persistence generalises the highly successful theory of persistent homology and addresses several situations which are not covered by that theory. In this paper we develop ...

geometrical structure, nuclear magnetic resonance (n1,1it) chemical shielding tensors, and chemical shiftsof silicon and carbon nucler are investigated for twn infinite size zigzag and armchair single-walled siliconcarbide nanotabes (sicnts). geometrical structures of sients, sit bonds and bond angles of st and cvertices in both zigzag and armchair nanotubes, indicate that bond lengths are appr...

Herein, we report on a zigzag graphene superconducting junction with superconductor sandwiched in between two magnetized nanoribbons, where the valley and pseudoparity mixing are shown to bring about peculiar properties. We find that bipolar spin diode spin-conversion ferromagnetic configuration as well quantum entanglement antiferromagnetic one exhibited. The noncollinear angle combined arbitr...

Microfluidic platforms have greatly benefited the biological and medical fields, however standard practices require a high cost of entry in terms of time and energy. The utilization of three-dimensional (3D) printing technologies has greatly enhanced the ability to iterate and build functional devices with unique functions. However, their inability to fabricate within microfluidic devices great...

the reaction mechanism between (h2c) and (7, 0), zigzag single-walled carbon nanotubes(zswcnts) on two different orientation of c-c have been studied by semi empirical am!method. the activation barriers of (h2c) adding to (7, 0) zswcnt are computed and compared.the effects of diameters of zigzag swcnt on their binding energies were studied

In this paper we introduce a new class of facet-inducing inequalities for the Windy Rural Postman Problem and the Windy General Routing Problem. These inequalities are called Zigzag inequalities because they cut off fractional solutions containing a zigzag associated with variables with 0.5 value. Two different types of inequalities, the Odd Zigzag and the Even Zigzag inequalities, are presente...

In [2], the concept of zigzag function was introduced in relation with oblivious transfer [17]. This subject has later been studied in [21, 9, 5]. The definition of zigzag functions has been generalized to s-zigzag functions for 2 ≤ s ≤ n. It turns out that zigzag functions are also interesting combinatorial objects, thanks to their relation with self-intersecting codes and orthogonal arrays [2...
