Superhydrophobic paper substrates were patterned with high surface energy black ink using commercially available desktop printing technology. The shape and size of the ink islands were designed to control the adhesion forces on water drops in two directions, parallel ('drag-adhesion') and perpendicular ('extensional-adhesion') to the substrate. Experimental data on the adhesion forces shows goo...

Addition is the most complex operation in a floating-point unit and can cause major delay while requiring a significant area. Over the years, the VLSI community has developed many floating-point adder algorithms aimed primarily at reducing the overall latency. An efficient design of the floating-point adder offers major area and performance improvements for FPGAs. This paper studies the impleme...

Lop Nur is a famous dried lake in Xinjiang of northwest China and finally lost its last drop of water in 1960s. It is well known for its “Human Ear Shape” feature in optical remote sensing images. Likewise, “Ear” feature is shown in Synthetic Aperture Radar (SAR) images, and even larger because of penetration effect [1, 2]. There are some explanations about external causes of the “Ear” feature ...

This paper discusses the potential problems due to cultural differences, which foreign companies may face in Brazil concerning information security. Top 3 investing countries in Brazil, namely US, Netherlands, and Japan are examined. Potential problems concerning the management of people in information security are developed by using Geert Hofstede’s framework and based upon the authors’ experi...

The quantitative study of the arid Lop Nur lake basin is significant to investigate the environmental changes in the arid area of northwestern China and extremely arid areas of Eurasia in general. Synthetic aperture radar (SAR) imagery, with its penetration capability and advantages for studying geological phenomena on a large spatial scale, is very suitable for analyzing the subsurface of the ...

In some cases, global businesses expansion leads to human-related problems due to cultural differences between investor countries and investee countries. This study focuses on such problems in the area of information security. Potential problems which British companies may face in rising economies are discussed here. Russia, India and China, where UK is one of the key investors, are examined. P...

The object of this study was to investigate whether level of processing (LOP) modulates enhanced memory performance for emotional stimuli, and, if so, whether the LOP effects relate to their gist and details. During the study phase, participants were presented with colourful pictures with negative, neutral and positive valences and encoded the emotional pictures under either a semantic (living/...

The linear ordering problem (LOP) arises in a number of divers domains. The notoriously hard class of LOP instances, even for sizes L < 50, is represented by Paley tournament graphs. Instances of these graphs, along with best-known-values (BKVs), some of them proven optimum, are now readily available on the Internet. There is no published record of asymptotic complexity to solve instances of Pa...

Given a matrix of weights, the Linear Ordering Problem (LOP) consists of finding a permutation of the columns and rows in order to maximize the sum of the weights in the upper triangle. This NP-complete problem can also be formulated in terms of graphs, as finding an acyclic tournament with a maximal sum of arc weights in a complete weighted graph. In this paper we first review the previous met...

The computational identification of genes in DNA sequences has become an issue of crucial importance due to the large number of DNA molecules being currently sequenced. We present a novel neural network based multi-classifier system, MultiNNProm, for the identification of promoter regions in E.Coli DNA sequences. The DNA sequences were encoded using four different encoding methods and were used...
