Gestural operations on touchscreens will play an essential role in the future HCI. Pinch gesture is the most common one, and its two operations: zooming and rotation, are usually performed on touchscreens device. At present, previous studies have not specifically investigated the interaction between visual menu design and the modes of gestural operations. This study aimed to determine how various visual menu designs affect users' performances (task completion time and accuracy) and subjective ratings (comfortability and preference) in using pinch zooming and rotation. The results showed that visual menu designs did not significantly affect performance time and accuracy. However, the design significantly affected participants' perceived comfort and preferences, presumably attributable to compatibility between the mental models formed based on the menu design and the explicit feedback from the modes of operations. The study revealed that despite no significant effect of different visual menu designs on user performance and gestures, users might have preferred one alternative over another and compatibility between menu designs and operational mode must be taken into consideration for gestural operations on touchscreens.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"24 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":"126909643","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}

This is because in survey jobs that require extensive documentation of photographs, photo positioning information allows surveyors to recognize the location of photo objects in the survey and ease the process of data management. Currently, smartphones are equipped with positioning features using GPS and or Assisted-GPS (A-GPS) which can provide sufficient positioning for geotagging photos. However, in the execution of certain surveys there is a need for more precise positioning than the standard GPS/A-GPS positioning features of the smartphone. One way to improve geotagging position accuracy is to use an external RTK GPS module integrated with a smartphone. This paper discusses the making of Android-based smartphone applications for geotagging using an external RTK GPS module. In this paper also discussed the advantages and disadvantages of the applications that have been made, as well as the opportunities and limitations of the use of such applications.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"3 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":"114341284","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}

Three points Sangihe Geodynamic monitoring network has been defined since 2014, which are SGH1, SGH2 and SGH3. In this study, the quality of the network has been analyzed and used for the purpose of geodynamics study based on 2014 and 2015 epochs GNSS data measurement. The results show that the accuracy and reliability of the network based on A-optimality, E-optimality, S-optimality, I-optimality and D-optimality criteria meet the minimum criteria, therefore the network can be used for geodynamics studies.

Recently, the investigations of stratified flow have widely covered various aspects of the flow, such as the liquid hold-up. An image processing technique devotes numerous advantages related to the abilities of non-intrusive measurement and quantitative visualization. The aim of the present work was to implement the image processing technique to study the characteristics of the stratified flow. Here, the observations were conducted in a transparent horizontal pipe with inner diameter of 50 mm. Air and water were used as the working fluid. The liquid superficial velocity (JL) was between 0.005 m/s to 0.05 m/s while the gas superficial velocity (JG) was between 0.94 m/s to 6.00 m/s. The data was processed by using the image processing algorithms that have been developed in the previous study. As a result, qualitative and quantitative identifications of each stratified flow patterns (smooth, ripple, and roll) have been carried out by using an image processing technique. The effects of gas and liquid superficial velocities to stratified flow behaviors were also obtained. Moreover, this study proved that the developed algorithm has been successfully implemented in the present stratified flow case. Furthermore, it can be a promising method to be used in other cases of stratified flow and validation of the available CFD simulation models on stratified flow in horizontal pipes.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"86 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":"133464864","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 application of wireless power transmission continuously charges a tire pressure sensor battery is considered as a case-study. In order to charge the battery of tire pressure sensor, a prototype wireless power charging was designed and validated. Based on the prototype, the receiver module of wireless power charging was put on the small rotating wheel, and various of rotational speed was applied to know the effect of rotational motion on its induction voltage. The result experiments show that linear increase of receiver coil rotational speed gives linear increase to the induction voltage of receiver coil, and thus it gives effect both current and power load too.

At the local government level, this includes spatial planning, land management, taxation, and the issuance of building and site permits. Utilization of geospatial information in Indonesian local government was started more than 25 years ago. However, there was a high variation in the intensity, frequency, and types of geospatial information utilization. In a particular local government, there was also a variation of use among local government agencies. This paper aims to portray and analyses the current status of geospatial information utilization in Indonesian local government. Quantitatively, the information was obtained from questionnaires distributed to 24 districts and seven cities. The questionnaire covered areas of data availability, utilization, and management of geospatial information. For every district and city, around 20 to 30 questionnaires were sent, to gather information from all local governments agencies. Qualitatively, observations and in-depth interviews were conducted to collect information on the plans, progress, and challenges in geospatial information utilization. In general, the utilization of geospatial information is progressing steadily with some cities or districts made significant achievement while others still struggling in defining geospatial policies. Local governments have limited staffs with expertise in spatial data handling. Some recommendations to overcome the challenges and impediments are presented. Recent central government initiatives on national spatial data infrastructure and one map policy, are essential to speed up the process of creating better environment governance in local government.","PeriodicalId":196768,"journal":{"name":"2018 4th International Conference on Science and Technology (ICST)","volume":"1 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":"130786642","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 model simulation was established using DeltaEC freeware. For validation purposes, the simulation was conducted on similar geometrical configuration with that on the experimental set up. The resonator diameter was straight, tubular shape with inside diameter of 52 mm. The simulation is then enhanced to predict the thermo acoustic performance on varied resonator diameter of 27 mm, 41 mm, 78 mm and 90 mm. Results revealed that the simulation of thermo acoustic engine with 52 mm diameter generated acoustic power of 20,.737 watts. On the validation, this power has a deviation of 9% with that on the experimental data.
