A new system of hexadecimal and base-256 numerals is proposed whose digit shapes are based on binary numerals. The proposed numerals are implemented in open source fonts and integrated into popular editors (Notepad++ and Eclipse) to prove the concept.
In an earlier paper we introduced Lévy base correlation. In this paper we look at base expected loss at maturity both in the Gaussian copula and Lévy based models and link it to base correlation in these frameworks. We report on the existence of smile in both base correlation curves and discuss different interpolation methodologies in view of absence of arbitrage. Finally we discuss the propert...
ABSTRACT Background and objectives: Synthesis and characterization of several metal complexes (metal ions: Co2+, Ti4+ and Ce3+) of macroacyclic Schiff base ligand have been reported. The Schiff base ligand is prepared from the condensation reaction of 1, 4-di-(4-fluoro-2-aminophenoxy) butane with salicylaldehyde in ethanol. In addition, antibacterial ...
با توجه به پیشرفت علم در جهان و ایران ، امروزه شرکت های دانش بنیان که با ایجاد کسب و کار دانش محور به منظور تبدیل پایدار دانش به ثروت تشکیل شد و به توسعه اقتصاد دانش محور در جامعه کمک می کند، روی کار آمده است که یکی از فعالیت های این شرکت ها در زمینه سلول درمانی و استفاده از سلول های بنیادی است، با پیشرفت علم پزشکی، استفاده از سلول های بنیادی به خصوص سلول های بنیادی رویانی که کارایی بیشتری دارد...
in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...
introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...
abstract background: invasive fungal infection is an opportunistic infection caused commonly by mucoraccae and aspergillus. it mostly occurs in patients with underlying disease. since it has a high mortality and morbidity rate, considering a treatment strategy seems necessary. objective: since there has not been a clear protocol for treating these patients, we decided to establish a protocol ...
there are many occasions where the base of a robotic manipulator is attached to a moving platform, such as on a moving ship, terrain or space shuttle. in this paper a dynamic model of a robotic manipulator mounted on a moving base is derived using both newton-euler and lagrange-euler methods. the presented models are simulated for a mitsubishi pa10-6ce robotic manipulator characteristics mounte...
