This paper discusses the topic of uncertainty in the context of architecting embedded software and systems. It presents links between complexity and uncertainty, and identifies different kinds of uncertainty. Based on this, it elaborates why uncertainty arises in the architecting of softwareintensive systems, and presents ten different tactics that can be employed to deal with uncertainty and m...

We present a discussion of embedded vortices in general Yang-Mills theories. The origin of a family structure of solutions is shown to be group theoretic in nature and a procedure for its determination is developed. Vortex stability can be quantified into three types: Abelian topological stability, non-Abelian topological stability, and dynamical stability; we relate these to the family structu...

abstract: this paper presents the results of pullout tests on uniaxial geogrid embedded in silica sand under monotonic and cyclic pullout forces. the new testing device as a recently developed automated pullout test device for soil-geogrid strength and deformation behavior investigation is capable of applying load/displacement controlled monotonic/cyclic forces at different rates/frequencies an...

background &objective: breast cancer is the most common female malignancy. detection of dna of human papillomaviruses (hpvs) in breast carcinomas suggests that the virus may play a role in the pathogenesis of this disease. the aim of this study was to evaluate the frequency of hpvs genotypes 6, 11, 16, 18 and 31 in paraffin-embedded tissue samples of invasive breast carcinomas. methods: thr...

large size direct shear tests (i.e.300 x 300mm) were conducted to investigate the interaction between clay reinforced with geogrids embedded in thin layers of sand. test results for the clay, sand, clay-sand, clay-geogrid, sandgeogrid and clay-sand-geogrid are discussed. thin layers of sand including 4, 6, 8, 10, 12 and 14mm were used to increase the interaction between the clay and the geogrid...

a simple, highly sensitive, accurate and selective method for determination of trace amounts of cu2+ in water samples was reported. in this paper, isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (iide) in order to prepare an effective sorbent for the preconcentration and determination of cu. the sorption capacity of isopropyl 2-[(isopropoxy carbothioyl)disulfanyl]ethanethioate (ii...

Chaos is embedded to the he Charged System Search (CSS) to solve practical optimization problems. To improve the ability of global search, different chaotic maps are introduced and three chaotic-CSS methods are developed. A comparison of these variants and the standard CSS demonstrates the superiority and suitability of the selected variants for practical civil optimization problems.
