Discrete{time analysis (DTA) is a modelling technique that is mainly applied to the analysis of communication systems. In this paper, we show how DTA can be adopted to the numerical analysis of manufacturing systems. The modelling concepts of DTA are introduced and the advantages of DTA over other methods like discrete{event simulation are indicated. We apply DTA to two sample applications, nam...

This paper presents a systematic study of the surface chemistry, porous texture and adsorptive characteristics of prepared new activated carbon using Persian mesquite grain. Several techniques and methodologies such as, proximate analysis, N2 adsorption–desorption isotherms, scanning electron microscope (SEM), Fourier transform infrared spectroscopy(FT-IR), X-ray Diffraction (XRD), X-ray photoe...

Two nano-sized mixed-ligand Cd (II) coordination polymers; [Cd (4,4' -bpy) (C4H4O4)].1/4 H2O (1) and[Cd(bpy)1.5 (NO3)2].3H2O (2) (bpy=bipiridine) were synthesized by a sonochemical method and characterized by elemental analyses, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The cry...

CuO nano particles were obtained by calcination of nano-sized  [Cu(C4H4O4)(bipy)(H2O)2].2H2O (1) and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) (2) which are two  Cu(II) coordination polymers. The two coordination polymers [Cu(C4H4O4)(bipy)(H2O)2].2H2O and [Cu(2‚2′-bipy)](C4H4O4)0.5(NO3)(H2O) were synthesized and characterized by Fourier transform infrared spectra (FT-IR spectroscopy), thermal gravim...

In current study, the synthesis and characterization of novel thermally stable polyimides (PIs) containing an 1,3,4-oxadiazole moiety based on a diamine, i.e. 2,5-bis(3-amino-4-methyl benzene)-1,3,4-oxadiazole (BAMO), have been reported. The polymers were characterized using FT-IR and elemental analysis (CHN). Thermal and mechanical behaviours of the prepared PIs were studied by thermo-gravimet...

Bu çalışmada, pomza hafif agregası ile değişik oranlarda çimento dozajı arttırılarak oluşturulan harç karışımlarına tinkal atığı eklenmiştir. Beton harçların üretiminde 0-4 mm boyutundaki Nevşehir yöresi asidik kullanılmıştır. Karışımların su/çimento oranı 0.50 olarak sabit tutulmuştur. Üç farklı dozajında her dozajda kontrol ve katkılı olmak üzere toplam 6 karışım oluşturulmuştur. Çeşitli dene...
