Abstract

We report in this work the results of fabricating high quality MEH-PPV and MEH-PPB thin films using spincoating method by proper choice of a solvent, weight concentration and spinning speed. It is found that the films prepared from toluene solutions of weight concentration around 5 % at spinning speeds of 2000 rpm show the highest quality of uniform thickness of d = 540 nm for MEH-PPV and d = 450 nm for MEH-PPB with normalized surface roughness (Ra/d) of 0.3 % for MEH-PPV and MEH-PPB.

Abstract

Effect of growth temperature on crystalline structure of YBCO thin films have been studied by a MOCVD method using a vertical reactor with a flow guide. At growth temperature between 600°C and 675°C, the films are composed of a mixture of a-axis and c-axis oriented phases, while at growth temperature of 700°C or higher, the a-axis-oriented phase disappears. At these growth temperatures, only c-axis-oriented phases are existing on the films. Film grown at 680°C or higher have the composition of Y : Ba : Cu is 1 : 2 : 3, as confirmed from EDAX spectra. Films deposited at 700°C have critical temperature around 87.4 K.

Abstract

Simulation of CO2 dispersion has been carried out for Semarang region and its surrounding which covers area of (50 x 50) km2, in September 1998 (represent dry season), by using software of LADM that developed by CSIRO, Australia. Aerology data, except wind data, for this simulation is observed by launching radiosonde at Ahmad Yani airport area (110,4°E and 7,0°S), and this location is taken as center of the simulation. Wind data is obtained from Meteorological and Geophysics Agency. By simulating two CO2 emission sources that placed in Ungaran regent and north east of Semarang, close by bus terminal of Terboyo, it is found that the CO2 dispersion pattern tends to spread northwards and north-westwards; covering northern and north western of Semarang, Java sea and Kendal Regency. Based on the CO2 dispersion pattern given by LADM and by considering field conditions including topography and CO2 emission sources therefore are measurements of CO2 in six sites in the same season in 1999. Jomblom bay (Kendal), Tanjung Mas harbor, and Graha Padma Settlement represent the spreaded area of CO2 (polluted area of LADM version) that borne in Semarang city. While Candi, Gubug (Grobogan) and Dan Sat Brimob complex represent the unspreaded area of CO2 (cleaned area of LADM version). Dan Sat Brimob and Tanjung Mas harbor are located closed by CO2 emission sources (road and industry). The other sites have no significant pollutant emission sources, thus the CO2 emission sources can be neglected in the sites. Analyzing of measurement of CO2 in the sites show correlation with the dispersion of CO2 pattern of LADM.

Abstract

Research on optical interferometry has been applied to examine object deformations caused by static & dynamic loading. This method makes use of coherent beam phase alteration recorded in image recording system. In general, the system consists of three systems i.e. optical system, image recording system, and image processing system. Optical system (optical set-up) will determine the deformation shape, image recording system which function as recording before (initial condition) and after deformation. Image processing system will determine the deformation. By means of static & dynamic tests on aluminum plate, it is shown that this system can lends itself to determine object deformation and has light beam order of accuracy. Therefore, deformation distribution can be quantitatively interpreted by analyzing the fringe pattern.

Abstract

This paper describes a non-linear inversion method employing simulated annealing technique that imitates a thermodynamic process in which a substance is cooled down slowly to achieve an equilibrium state with a minimum energy. The method was applied to invert 1-D magnetotelluric data in which the model parameter is resistivity varied with depth. Model perturbations carried out in search for a minimum data misfit. Inversions of synthetic and field data showed satisfactory results. By considering equivalence problems, synthetic models were resolved relatively well with data misfit around 10%. Inversions of field data showed subsurface resistivity distribution that agrees well with the geological condition of the surveyed area.
