THERMAL EXPANSION BEHAVIOR OF THE Ba0.2Sr0.8Co0.8Fe0.2O3−δ (BSCF) WITH Sm0.2Ce0.8O1.9
Nanostructured perovskite oxides of Ba0.2Sr0.8Co0.8Fe0.2O3−δ (BSCF) were synthesized through the co-precipitation method. The thermal decomposition, phase formation and thermal expansion behavior of BSCF were characterized by thermogravimetric analysis, X-ray diffraction (XRD), and dilatometry, respectively. XRD peaks were indexed to a cubic perovskite structure with a Pm3m (221) space group. All the combined oxides produced the desired perovskite-phase BSCF. The microstructures were characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The TEM analysis showed that BSCF powders had uniform nanoparticle sizes and high homogeneity. The cross-sectional SEM micrograph of BSCF exhibited a continuous and no delaminated layer from the electrolyte-supported cell. The thermal expansion coefficient (TEC) of BSCF was 16.2×10-6 K-1 at a temperature range of 600°C to 800°C. Additional experiments showed that the TEC of BSCF is comparable to that of Sm0.2Ce0.8O1.9 (SDC) within the same temperature range. The results demonstrate that BSFC is a promising cathode material for intermediate-temperature solid-oxide fuel cells

Clay from Gema Village, Kampar Regency, Riau Province has been applied as an adsorbent. The increase of clay\u27s adsortive capacity can be done by modification. This study was aimed to use the activated clay to improve the quality of bulk cooking oil. The adsorbent preparation was began with activation process by using 0,5 M H2SO4, for 3 hours, and stirring rate 500 rpm. Activated clay showed the increase the intensity of quartz and montmorillonit, and accompanied by the loss of muscovite and kaolinite. The parameters that were used in this study were peroxide value, acid value, water content, odor, and colour.

The obtained result showed that the activated clay 0,5 M H2SO4 was able to decrease the acid value, and water content, respectively 54,55%, 48,75% with 120 minute and 7 gram weight of activated clay, it was also able to decrease peroxide value 39,64% with 60 minute and 7 gram weight of activated clay, and the color of bulk cooking oil was more clear, but it\u27s smells like clay
Mobile ad hoc network testbed using mobile robot technology
MANET (Mobile Ad Hoc Network) researchers have shown increased interest in using mobile robot technology for their testbed platforms. Thus, the main motivation of this paper is to review various robot-based MANET testbeds that have been developed in previously reported research. Additionally, suggestions to heighten mobility mechanisms by using mobile robots to be more practical, easy and inexpensive are also included in this paper, as we unveils ToMRobot, a low-cost MANET robot created from an ordinary remote control car that is capable of performing a real system MANET testbed with the addition of only a few low-cost electronic components. Despite greatly reduced costs, the ToMRobot does not sacrifice any of the necessary MANET basic structures and will still be easily customizable and upgradeable through the use of open hardware technology like Cubieboard2 and Arduino, as its robot controller. This paper will also include guidelines to enable technically limited MANET researchers to design and develop the ToMRobot. It is hoped that this paper achieves its two pronged objectives namely (i) to facilitate other MANET researchers by providing them with a source of reference that eases their decision making for selecting the best and most suitable MANET mobile robots for real mobility in their MANET testbeds (ii) to provide MANET researchers with a prospect of building their own MANET robots that can be applied in their own MANET testbed in the future

Similarity Based Entropy on Feature Selection for High Dimensional Data Classification
Curse of dimensionality is a major problem in most classification tasks. Feature transformation and feature selection as a feature reduction method can be applied to overcome this problem. Despite of its good performance, feature transformation is not easily interpretable because the physical meaning of the original features cannot be retrieved. On the other side, feature selection with its simple computational process is able to reduce unwanted features and visualize the data to facilitate data understanding. We propose a new feature selection method using similarity based entropy to overcome the high dimensional data problem. Using 6 datasets with high dimensional feature, we have computed the similarity between feature vector and class vector. Then we find the maximum similarity that can be used for calculating the entropy values of each feature. The selected features are features that having higher entropy than mean entropy of overall features. The fuzzy k-NN classifier was implemented to evaluate the selected features. The experiment result shows that proposed method is able to deal with high dimensional data problem with average accuracy of 80.5%

Ketahanan Genotipe Kedelai terhadap Kekeringan dan Kemasaman, Hasil Induksi Mutasi dengan Sinar Gamma
The study aimed to classify soybean genotypes that are tolerant, moderate and sensitive to drought and acidity. The results are expected to give a contribution in the development of Soyban on dry land and acid soil. Increasing of genetic diversity was carried out through mutation induction by gamma ray in soybean seeds. The experiment was conducted in green house by using the method in the form of a two-factor factorial design laid out in the draft group. The first factor was the variety (V) which consisted of three kinds, namely soybean Menyapa varieties (v1), Orba (v2), and Tanggamus (v3). The second factor was the dose of gamma-ray irradiation (D) consisted of 4 doses of 0 Gy (d0), 25 Gy (d1), 50 Gy (d2), and 75 Gy (d3) at concentrations of PEG and Al which showed that the level of diversity the biggest concentration of 30 previous trials of PEG+10 ppm Al. The volume of nutrient solution (Hoagland's) maintained in accordance with the initial volume by adding distilled water, and the solution was maintained at pH 4 using NaOH and HCl 1N. The results showed that the grouping was based on drought tolerant and acidity as follows: genotypes tolerant were varieties Menyapa 50 Gy gamma irradiation, variety of Orba 25 Gy of gamma irradiation, gamma irradiation variety Tanggamus 0 Gy, 25 Gy, 50 Gy of gamma iradiation. Moderate genotype were varieties Menyapa 75 Gy of gamma irradiation, variety Orba 50 Gy, 75 Gy of gamma irradiation, variety Tanggamus 75 Gy of gamma irradiation; genotype susceptible were variety Menyapa 0 Gy, 25 Gy of gamma irradiation; variety Orba without gamma irradiation of 0 Gy
Scattering from supramacromolecular structures
We study theoretically the scattering imprint of a number of branched
supramacromolecular architectures, namely, polydisperse stars and dendrimeric,
hyperbranched structures. We show that polydispersity and nature of branching
highly influence the intermediate wavevector region of the scattering structure
factor, thus providing insight into the morphology of different aggregates
formed in polymer solutions.Comment: 20 pages, 8 figures To appear in PR
