FRDB, an extension of RDB using a soft computing technique, fuzzy theory. Using our relational formulas of relational calculus, we can denote its properties by simple and correct formulas. Also, we can prove its properties formally using relational calculus. There are many applications of FRDB such as managing hyperlinks of web pages, customer relationship management (CRM), etc. Our motivation is developing formal verification tools for a software system using FEC of FRDB. We also formalize database operations such as “projection”, “selection”, and “natural join”. We prove several elementary properties of natural join operations using our formalization.","PeriodicalId":191373,"journal":{"name":"2017 International Conference on Applied Computer and Communication Technologies (ComCom)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129000480","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}

In terms of purpose, game has two types, which is serious game and non-serious game. As learning media, serious games need to have ability to motivate its player in order to play the game until the end so the player can finish the game while understanding learning materials given in the game. Therefore, the quality of serious game should be measured, like any other software. When it comes to measure serious games, previous models can't do the job well since all of them have no way to measure the game's content, especially to measure the content that can improve player's motivation. This paper proposes a new game measurement metric to measure the game quality factors, especially to measure serious game contents that can motivate its players. The result of this paper is a metric table consisted of measureable factors and type of test to measure them.","PeriodicalId":191373,"journal":{"name":"2017 International Conference on Applied Computer and Communication Technologies (ComCom)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114925443","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}

{"title":"An analysis of optimal capacity in cluster of CDMA Wireless Sensor Network","authors":"Dwi Widodo Heru Kurniawan, A. Kurniawan, M. S. Arifianto","doi":"10.1109/COMCOM.2017.8167080","DOIUrl":"https://doi.org/10.1109/COMCOM.2017.8167080","url":null,"abstract":"Interference is one of the factors influence the number of active sensors of the CDMA Wireless Sensor Network as it affects Eb/I0 on the received signal. The higher the interference, the smaller the capacity is. One of the methods to minimize the interference is cluster formation in the CDMA Wireless Sensor Network. Using cluster, the interference can be minimized because transmission power to send data decreases as the sensor only transmits data to Cluster Head (CH), not directly to sink. There are two types of the interference on the CDMA Wireless Sensor Network, namely: intra-cluster interference (Multiple Acces Interference/MAI) and inter-cluster interference (Node Interference/NI). The intra-cluster interference is overcome by using power control so that the received power in the Cluster Head from every sensor is the same. However, the Cluster Head is not able to control sensor's transmission power from other clusters, so interference from other cluster cannot be managed. The research analyzes the factors influencing inter-cluster interference comprising of distance between clusters, cluster size, influence of sensors located near cluster's border and the network capacity. The research shows distance and position of sensors will impact to inteference. If the distance between clusters rises 1.5 times, then it will reduce the power of interference signal by 8.6 dB. And the sensors at the border generate higher interference than other sensors. This problem is overcome by using layering technique, in that high power sensors at the border will send data through intermediary sensor. As a result this methode can reduce transmission power of the sensors at the border. Therefore, applying layering technique is capable of reducing interference of the sensors at the border. The research shows that if the layering radius is 0.7 of cluster size, it will generate minimum inter-cluster interference. Finally utilizing the cluster formation will increase the network capacity. If the network applies the unequal number of sensors in the cluster, it will increase 3% capacity compared to the equal number of sensors in the cluster.","PeriodicalId":191373,"journal":{"name":"2017 International Conference on Applied Computer and Communication Technologies (ComCom)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129045848","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}

Physical security is a type of computer security that secures the perimeter of an area. Anyone who has physical access to the computer controls it. The organization must physically secure its resources because it is easy to manipulate the computer through physical means. In this paper, a new mechanism is introduced to map out the pair of values in table of 4×4 scrambled keys. The initial seed comes from the parameters, strings of characters and numbers. This will minimize the number of key strokes because OTP codes sent via email will be keyed in using the XY coordinates.
