Some problems that commonly stated by students who learn geography are too much information and definitions to be memorized, not interesting or enjoyable, difficult and so on. The use of Information and Communication Technology (ICT) media hopefully can help to solve this problem. Currently, most students have been familiar using mobile devices. Therefore, it is a potency to develop a geography learning application especially for mobile devices. This paper exhibits the development of geographic mobile learning application. The employment of Linked Data as information sources, i.e. DBpedia and LinkedGeoData, can help us to provide rich information with minimum efforts. The evaluation showed that the application got more than 85% positive responses in terms of ease of use, ease of learning, usefulness, pleasant and intention to use the application.

Neutron radiography is one of effective nondestructive methods for investigation of defects in the specimen. It has a capability to detect a light element, especially hydrogen, while other radiography cannot. In this study, the technique of fast neutron radiography using the (n, p) reaction has been developed. The (n, p) reaction is the nuclear reaction that converts fast neutron particles into proton particles. The recoiled proton produces from hydrogen-rich materials by the (n, p) reaction using the 14 MeV fast-neutron generator. To confirm the existence of (n, p) reaction, the experiment on the track-etching on CR-39 with proton particles is performed. The conditions of track etching are 6 N NaOH, a temperature of 60 °C, etching time of 4.5 hours. The X-ray image plate, BAS-MS type produced by FUJIFILM attached with a converter screen made by hydrogen-rich material (a cloth tape), is irradiated by 14 MeV of fast-neutron about 30 minutes. The results show that the range of particle track size from 5.214 μm to 17.962 μm. The proton particles is confirmed. To find an optimum converter screen condition for the radiography, several types of hydrogen-rich materials (cloth tapes, acrylic plates) with various thickness between 0.81 cm to 3 cm are irritated with 14 MeV neutron produced by a fast-neutron generator. The X-ray image plate BAS-MS type is again applied to record the charge particle effect on a radiography screen. For each test condition, The Photo-Stimulated Luminescence (PSL) is used to determine the quality of images, including the parameters of the image contrast and unsharpness. According to the test results, a cloth tape with 0.81 mm of thickness is selected as an optimum converter screen condition which provides a high PSL of 154.9 PSL/mm2, and relatively high contrast with acceptable unsharpness parameters.

The aim of this research was designed, to determine the acute toxicity of 80% ethanolic leaf extract from S. trilobata (STLE) in Wistar rats. Rats were divided into 4 groups; group I: controls, group II-IV: rats received STLE 1000, 1500 and 2000 mg/kg respectively. A single oral administration of STLE to the rats revealed that all the doses of STLE did not produce any signs or symptoms of toxicity. And also, the mortal rat was not observed during a period of an observation within 24 h and the further period lasting 14 days. Furthermore, STLE did not affect the body weight, relative organ weight (liver, pancreas, kidney and heart), hematological values including hemoglobin, hematocrit, RBC, MCV, MCH, MCHC, WBC, neutrophil, lymphocytes, monocyte and platelet, and blood biochemistry including alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN) and creatinine. Moreover, STLE did not alter blood cell characteristics and ultrastructure of red blood cells. These findings indicate that the leaf extract from S. trilobata has no acute toxicity with LD50 higher than 2000 mg/kg. It is therefore, safe and can be used as traditional medicine or complementary diet without any effect on hepatic and renal function.

In this work, we focus on increasing surface area of Pt layer used as a counter electrode in dye-sensitized solar cells (DSSC). The increasing surface area of Pt layer was prepared by coating Pt layer on FTO template. The FTO template was fabricated by dipping FTO glass in hydrochloric (HCl) acid with concentration of 0.016, 0.324 and 1.62 M and immersion time of 5, 15, 30, 45 and 60 s, respectively. The Pt layer counter electrode was coated on FTO template by electrochemical technique with Pt(NH3)4Cl2 powder dissolved in HCl solution. The coating current was fixed at 25 mA and deposition times were varied from 10, 30 to 60 min. The sheet resistance, surface roughness and structural property of FTO substrate were examined by Van der pauw technique, atomic force microscopy (AFM) and X-ray diffraction, respectively. The AFM image shows that surface roughness of FTO template increases with increasing immersion time but sheet resistance decreases. The high surface area of FTO template can decrease sheet resistance because of increasing conducting Pt surface area. Based on AFM results, the surface area of Pt layer is highest with HCl concentration of 0.016 M and immersion time of 60 s. The DSSC were consisted of working electrode (FTO, TiO2 blocking layer and TiO2 porous layer) sandwich with the Pt counter electrode and iodide liquid electrolyte, respectively. The cell efficiency was measured by solar simulator operation at 1000 mW/cm-2. The maximum cell efficiency of 2.78% was achieved from Pt deposition time of 60 min. Our results show that this simple preparation of Pt layer can be applied as a counter electrode for dye-sensitized solar cell.

Particle Swarm Optimization (PSO) has been proven to solve various applications by most applications using the real problem-space. In some specific problem, the discrete problem-space is selected on PSO that getting the solution result slowly by cause of sticky on local solution, and also the researcher cannot modify or difficult to understand how to improve the performance finding solution. The researcher many be tried to adjust velocity value by giving a new c1, c2 and weight to be a smaller or a larger value. This research proposed how to apply roulette wheel select to improve PSO on the discrete problem-space. Experiment tested the idea by a toll-keeper scheduling and a numerical function. Both problems created parameters inform discrete problem-space. The experiment result showed that PSO with roulette wheel selection taking the solution quickly.

Collaborative filtering approach recommends new items to users by aggregating opinions of others who present highly similar preferences. Usually similarity computation techniques in collaborative filtering involved with analyzing common aspects between users. Limitation of collaborative filtering techniques is that lacking of reliability can be found in the output when a very small number of common aspects are considered in similarity computation. This conduces to disrepute of opinions and may not only affect to recommendation quality, but the system might also waste time to process poor quality opinions. To alleviate this limitation, we proposed the techniques how to locally estimate reliability of opinions or neighbors based on the number of common aspects presented by users. Next we proposed the Neighbor Filtering Approach to reduce the number of low quality opinions or neighbors who are not likely to be creditable in recommendation process. We also suggested new process structure which incorporates the Neighbor Filtering Approach into the classical collaborative filtering recommender system. Finally we conduct the collaborative filtering system according to the new process structure and evaluate the results by comparing them with the baseline from the classical system. The results show that the effort in recommendation process can be reduced without compromising its recommendation quality.

As the number of transistors in a single Very Large Scale Integrated (VLSI) chip is countless, the IC design has become much more complex. Floor-planning is an essential design step for hierarchical, building-module design methodology. Floor-planning provides an early feedback that evaluates the architectural decisions; estimates the chip areas; delays and congestion caused by wiring. As the technology advances, the design complexity increases and the circuit size gets larger. To cope up with the ever increasing design complexity, hierarchical design and intellectual property (IP) modules are widely used. This trend makes floor-planning much more critical to the quality of the VLSI design than ever. This paper presents an evolutionary algorithm called Craziness Based Particle Swarm Optimization algorithm (CRPSO) for floor-planning optimization of VLSI chip. CRPSO is a modified version of Particle Swarm Optimization (PSO) Technique and is employed to speed up the local search and to improve the precision of the solution. The main objective of floor-planning optimization is to minimize the chip area and the interconnection wire length. Floor-planning directly correlates to the cost of the silicon chip. The simulation results show that the CRPSO based floor-planning outperforms those of the other approaches reported in earlier literature.

The simulation results show that the CRPSO based floor-planning outperforms those of the other approaches reported in earlier literature.","PeriodicalId":251893,"journal":{"name":"2015 International Conference on Science and Technology (TICST)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133936524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, website has play an important role for the business. Almost every company have its own website to convey some information for a variety of purposes including marketing, after sales services, cataloging, etc. Accordingly, the larger the company the more information or content that must be put on the website. One measure of the amount of information available on website is how many links available in the website. In this paper, we observe the relationship between company size and the amount of content or information available on their website that will be reflected by the amount of links there. In this study, we use n=25 large company owned website. We employ correlation analysis to reveal the relationship between company size and the amount of website links. However, the company size do not relate specifically to it's representing website. The result of the study shows that the relationship is not exist. We have also examine the type of information contained in these links.
