Those devices are designed for applications such as activity or vital-signs monitoring, typically using Bluetooth/Zigbee technology to communicate with external devices under body-centric wireless communications system (BWCS). In addition, currently, microwave tomography (MWT) system is widely researched since it offers a portable, affordable and non-invasively modality. Study on interaction between the human body and electromagnetic (EM) waves inevitably must be evaluated for wearable and implantable antennas for BWCS or antennas/array for MWT system. Basically, the EM interaction includes two ways: an influence of the human body on the performance of antennas and an influence of EM waves on the human body. This paper studies on such phenomenon by designing two numerical phantom models particularly for head phantom, i.e. a homogeneous phantom model and multilayer phantom at 5.8 GHz. As for the head homogeneous phantom, it is set as a skull-mimicking tissue, whose permittivity and conductivity are set equally at 5.8 GHz. The multilayer head phantom is constructed by six layers namely skin, fat, skull, CSF (cerebrospinal fluid), brain and muscle. In this paper, a dipole is then put in proximity to the head phantom models for investigating the influence of such models on its performances at 5.8 GHz due to EM field interaction. The results show that the frequency center of dipole antenna tends to shift at lower frequency when situated close to the head phantom, comparing to the simulation in free space. Moreover, the width of beam-pattern of the dipole is significantly affected by phantom's structure. Finally, it can be stated that different structure of tissue-mimicking model will affect different phenomenon due to absorption properties for each structure.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121517459","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}

One way to improve the SLA is to minimize service downtime. This downtime is called with TTR (Time to Repair) which is an FMS (Fault Management System) performance indicator. The lower TTR values, the better the FMS performance. This research discuss the performance improvement by evaluating FMS business process, determine the components that lead to system failure, measure the value of a system failure probability with changes in the composition of its components, and obtain business process that improve FMS performance. FMS business process is represented in SOP of fiber optic fault handling process. MC (Markov Chain) method is used to determine the level of FMS business process performance for each process from open ticket to closed ticket. FTA (Fault Tree Analysis) method is used to determine the probability of system failure for various components composition in the FMS. The purpose of this method is to get a system that has a minimum system failure probability. The new system is then re-tested for its performance using MC method. With both methods we can obtain business process models that can improve the performance of FMS PT.

In this paper, one type of the DG i.e. Wind Turbine is optimally integrated in a power network for enhancing the performance of the network. A new variant of Genetic Algorithm (GA) dedicated in multi-objective optimization problems known as Non-dominated Sorting Genetic Algorithm II (NSGA-II) has been proposed for accomplishing the same. To aid the decision maker choosing the best compromise solutions from the Pareto front, the fuzzy-based mechanism is employed for this task. The NSGA-II is used to obtain the optimal integration and sizing of the DG in a suitable load bus of the system. Multi-objective functions are considered as the indices of the system performance viz: maximization of system loadability in system security and stability margin i.e. voltage and line limit whereas minimization of the real power loss of the transmission lines. Simulation studies are undertaken on modified IEEE 14-bus and a practical Indonesia Java-Bali 24-bus systems. Results show that the dynamic performance of the power system can be effectively improved by the optimal integration and sizing of the DG.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"110 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124884771","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}

However chaotic map which is widely used for image permutations like Arnold Cat Map (ACM) has a relatively low recurrence period so vulnerable to the known image attack. Besides, the key space Arnold cat map is also relatively low so vulnerable to brute-force attack and limited to N square matrix. ACM generally combined with other chaotic maps to produce the encryption that is more resistant to brute force attacks and the known image attacks. But there come with a cost, which is the additional process and the encryption can't be purely based on permutations that known robust to noise. Therefore in this paper we propose a chaotic permutation method which has a very large recurrence period and key space, and can be applied to M × N matrix. The proposed method is to apply the Chaotic Permutation Multi Circular Shrinking and Expanding Movement (CPMCM) which is controlled by the expanded key. Based on the analysis of chaos properties, the chaotic method meets the characteristics of the chaos system, with a very large recurrence period which is equal to the Least Common Multiple (LCM) of all real numbers N where N is the size of the permuted block. And also has a very large key space that is equal to N factorial. The Spearman correlation test also showed that among the permutation sequences are not correlated or random.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132951286","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}

Despite quiet places are mandatory for international standard observatories, noise may not be avoided due to natural conditions, such as HF signals arising from Sun's activities and ULF ones arising from Earth's activities, as well as anthropogenic sources from human activities during day times. On the other hand, geomagnetic signal processing, particularly for determinations of earthquake precursors needs uncontaminated data which are often regarded as night time values. While many papers using geomagnetic data have selected their own time span, actually no obvious limits have been commonly determined for the quietest time so far. Hence each region are necessary have their unique time span, since differences of socio-cultural and human behaviors over the world. This paper applies wavelet transformation to determine the quietest time range of geomagnetic signal processing for Japanese regions by de-noising of declination (the most sensitive geomagnetic values) of three INTERMAGNET observatories (i.e. Kakioka (KAK), Kanoya (KNY), and Memambetsu (MMB)). Comprehensive evaluations which are taken over selected days during ten years (2001-2010) resulted in the quietest time span of 21:48:00-00:53:00 at the Local Time. These results are in line with the time used by Hayakawa et al. (1996), e.g. 22:00:00- 02:00:00 LT, which are mostly referred by many researchers.","PeriodicalId":127270,"journal":{"name":"2015 International Conference on Quality in Research (QiR)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131148330","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}
