data visualization is the process of transforming data, information, and knowledge into visual form, making use of humans’ natural visual capabilities which reveals relationships in data sets that are not evident from the raw data, by using mathematical techniques to reduce the number of dimensions in the data set while preserving the relevant inherent properties. in this paper, we formulated d...

Single-walled carbon nanotubes (SWCNTs) offer a range of potential applications based on their unique one-dimensional structures. Theoretical calculations shows that their electronic structures depend strongly on their chiral vector indices (n,m) which determine the diameter and chiral angle. The graphite wrapping condition n-m=3p+q generates metallic tubes for q=0, while semiconducting tubes a...

We evaluate the goal of maximizing number individuals matched to acceptable outcomes. present two mechanisms that maximize assignments. The first is Pareto efficient and undominated—in terms assignments—in equilibrium. second fair for unassigned agents assigns weakly more than any stable mechanism in

The paper presents experimental results on quadratic assignment problem. The “scanning area” method formulated for radioelectronic equipment design is applied. For all more complex tests ours results are better or coincident with the ones known in literature. Conclusion concerning the effectiveness of method are given.

russian language, with regard to its grammar, is a language with its own special complexities, hardly found in other languages. although languages are different from each other, they have some similarities as well. the iranian learner, while learning russian, analyzes the sentences using patterns similar to his/ her native language patterns. occasionally, such native patterns cause the learner ...

Evidence for the quantum spin Hall (QSH) effect has been reported in several experimental systems form of approximately quantized edge conductance. However, most fundamental feature QSH effect, spin-momentum locking channels, never demonstrated experimentally. Here, we report clear evidence channels monolayer WTe2, thought to be a two-dimensional topological insulator (2D TI). We observe that c...

We consider a novel ultra-narrowband (UNB) low-power wide-area network (LPWAN) architecture design for uplink transmission of massive number Internet Things (IoT) devices over multiple multiplexing bands. An IoT device can randomly choose any the bands to transmit its packet. Due hardware constraints, base station (BS) is able listen only one band. Our main objective maximize packet decoding pr...
