Breastshot waterwheels represent a solution for this problem because they allow water energy potency up to 19 GW. To enable the use of waterwheels, this study develops a simple bucket shape that is easy to manufacture, considering its efficiency, and tests whether the kinetic energy contributes to the energy conversion process. There are three possible bucket shapes, namely straight, circular and thick. The computational fluid dynamic (CFD) method is a simulation approach used for determining the features of physical phenomena with six degrees of freedom (6 DoF). The study results show that the straight bucket has a better efficiency than other buckets do; the numerical results illustrate that this bucket has higher rotation and torsion than the others do. The straight bucket generates 120 W of power, with a potential energy of 318.8 W and efficiency of 37.6%. For the circular bucket, the power generated is 43.05 W, with an efficiency of 13.5%; this is better than the results for the thick bucket, which generates 19.3 W with an efficiency of 6%. Two-factor analysis of variance (ANOVA) without replication is used to determine the effect of the energy kinetic (inlet velocity) on the energy conversion process, and it shows no effect. Consequently, the breastshot waterwheel is classified as a reaction turbine. Thus, the straight bucket is recommended for use due to its higher generated power and easier manufacture compared with the other bucket shapes.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133505013","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}

The aims of this research is to produce a new technical of blood pressure. The homemade equipment set-up (called magnetic-coil equipment) is built by placing permanent magnet (strength: $(pmb{18pm 2})mathbf{x} pmb{10^{3}}$ gauss) and two series of receiver coils in 7×7 cm2 dimension (with 2,000 turns of coil wire 0.1 mm diameter). Output of receiver coils is connected to an amplifier (500 times to voltage) and a filter (20 Hz). Then, output of amplifier is connected to an oscilloscope and also a voltmeter. That set-up is based on the flowing speed of blood (in branchyalis artery) of 0.5 m/s and also the transversal relaxation time of blood of 0.2 s. The experiment testing is placed an arm's sample between 2 magnetic poles, then a hand is placed inside of receiver coils. Electromotive force induction is produced by magnetic dipole moment of proton in hydrogenic atoms flipping. That electromotive force (by magnet-coil equipment) is seen qualitatively by oscilloscope and measured quantitatively by the voltmeter. Electromotive force output values (of 12 samples) are 0 up to 11 volts. Those electromotive force are equivalent to systole and diastole on blood pressure of sample, so sistole and diastole are measured by sphygmomanometer reading in mmHg. The conclusion is the equivalent graph electromotive force induction versus blood pressure as exponential function.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132161584","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}

As a limited resource, the use of the frequency spectrum is regulated by the government by applying a licensing system. This research will calculate the price of spectrum license in LPWA according to Indonesian regulation. NB-IoT system will be used as input parameter in calculating the spectrum price in Indonesia.

The data showed that the maximal and comfort pinch in zooming were around 600 and 375 in pixels (160 and 100 in millimeters) for both hands while the range of rotation was 148-degree clockwise and 115-degree counterclockwise using the dominant hand. This study also found that participants preferred a 42-degree clockwise inclination to initiate rotation. Using non-dominant hands decreased the range of rotation but not the span of the pinch. Rotating with thumb fixed also significantly reduced the range of rotation.

The results show that the proposed solution is to filter information by using a recommender system. The system may need to be conducted by considering the tourists rating, collaboration, and products or services description. Further, the system should consider additional contextual information: location, time, social, and weather. Such a multidimensional context-based recommender system faces problems with the complexity of contextual data with many attributes used for filtering. Therefore, the additional contextual information on a context-based recommender system could be based on the expected contextual preferences.
