Since the occurrence of noise power uncertainty causes the detection performance of spectrum sensing techniques significantly degrade. In this paper, we propose two novel schemes of two-stage spectrum sensing for cognitive radio under environment as noise power uncertainty. The two-stage spectrum sensing technique combines two conventional spectrum sensing techniques to perform spectrum sensing by exploiting their individual advantages. The proposed two-stage spectrum sensing scheme exploits the merits of ED, MME and CAV techniques to determine the existence of the primary user. The ED performs spectrum sensing within a short time and offers a reliable detection at high SNRs condition. MME and CAV are robust to noise power uncertainty. Due to the combination of these techniques, the proposed schemes offer much more reliable detection when the uncertainty of noise power occurs. Even though the proposed technique takes the longest time in sensing period among two-stage spectrum sensing techniques, it is worth using this period of time to protect the primary user from harmful interference caused by the secondary user.","PeriodicalId":251023,"journal":{"name":"2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133599126","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}

Researchers have recently been trying to utilize people's social factors on many topics, such as those regarding recommendation systems, decision making, and behavior predictions. However, they have mainly focused on estimating final results of people's decisions or actions, and few of them have ever considered median processes that explain how people's attitudes would change. Furthermore, some realistic factors and questions, such as interactions between people and people and unequal relationships in social ties, that widely exist in our common lives and have significant impacts on attitudes and that influence processes have rarely been well considered. In this paper, we propose a novel way of modeling dynamic attitudes changing on the basis of people's social structures. We defined and used different parameters to test and then validate our ideas. We also compared the results from a method of machine learning and our proposed model. In conclusion, we described why our proposed model had high levels of scalability to suit different and complex social influence cases.","PeriodicalId":251023,"journal":{"name":"2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114353247","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 this study Elderly Music Taste Survey showed the preference scores of Taiwanese folk rhyme (M=24.62), popular music (23.46), traditional Chinese music (M=18.92), Chinese folk rhyme (M=14.23), and western classics(M=9.69) respectively. Significant improvement can be observed of both the dominant hand grip strength between pretest (M=20.60) and posttest (M=26.546) (t=2.313, p<; .05), and non-dominant hand grip strength pretest (M=18.369) and posttest (M= 24.708) (t=2.746, p<; .05) of the upper extremities. However the cognitive function test MMSE of the elderly between the pretest (M=27.67) and posttest (M=27.42) revealed no significant difference (t= .256, p= .803). The results were not affected by Gender nor by Age. We conclude that music instrument learning can effectively improve the upper extremity function and maintain the cognitive function of the elderly. By developing distance learning courses with mobile music instructors via both real-time interaction, video on demand demo, and uploads of learning records it can effectively energize the music learning experience of the elderly.","PeriodicalId":251023,"journal":{"name":"2015 Eighth International Conference on Mobile Computing and Ubiquitous Networking (ICMU)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125614084","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}
