You work with a circuit’s transfer function all the time in this course and make extensive use of the logarithmic scale: you are asked to Bode-plot a system’s frequency response in your homework assignments, lab reports, or maybe exams using Matlab, Agilent VEE, or even with bare hands, where the horizontal axis reads Frequency (log-scale). Good or bad, you will continue to see such plots here ...

The simetry of voltages, among other parameters, in to real power networks, is essential for ensuring optimum performances of the electrical systems and a standard quality of the energy. To control this, there are specific electric and electronic relays, which are hardware programmed to survey the symmetrical components of currents and voltages. The paper describe a software method to control t...

To study the expression of globin genes in human cells, human epsilon-globin genes were transferred into a K562 cell line, Bos, which synthesizes very low amounts of epsilon-globin mRNA. A plasmid (pSV2neo-epsilon) containing a complete epsilon-globin gene and 2 kilobases (kb) of 5' flanking DNA as well as a neomycin-resistance gene and a simian virus 40 origin of replication was transfected in...

The Fc-region of immunoglobulin E (IgE) comprising C epsilon 2, C epsilon 3, and C epsilon 4 domains is sufficient for binding to the alpha chain of the high affinity IgE-Fc receptor (Fc epsilon RI alpha). In order to identify the smallest Fc fragment capable of binding to the Fc epsilon RI alpha with high affinity, various regions of the IgE-Fc molecule were expressed in COS cells and investig...

Let G be a simple, connected graph and let A(G) the adjacency matrix of G. If D(G) is diagonal vertex degrees G, then for every real $$\alpha \in [0,1]$$ , $$A_{\alpha }(G)$$ defined as }(G) = \alpha + (1- ) A(G).$$ The eigenvalues form }$$ -spectrum $$G_1 {\dot{\vee }} G_2$$ {\underline{\vee \langle \text {v} \rangle {e} denote subdivision-vertex join, subdivision-edge R-vertex join R-edge two...

In fact, in the welding process, there are many problems that arise. Such as cracking caused by excessive stress Residual can result a decrease mechanical properties of material such brittle fracture, fatigue, and cracking. The purpose this study was to determine comparison tensile strength ASTM plate welded joints A36 with variations single vee butt bevel knowing effects ofpost-weldd heat trea...

Pembelajaran Biologi di Sekolah tidak lepas dari kegiatan praktikum baik dalam maupun luar Laboratorium. Kegiatan tentunya harus selaras dengan tuntutan kurikulum, sehingga lembar kerja perlu dianalisis dan dikaji lebih lanjut. Analisis dilakukan melalui metode deskriptif kualitatif menggunakan dua instrumen penilaian. Instrumen penilaian mengacu pada konstruksi pengetahuan diagram vee relevans...
