The said WCAN is an adaptation of CAN protocol which follows the data-centric approach. WCAN uses token frame method in providing channel access to nodes in the system. This method allow nodes to share a common broadcast channel by taking turns in transmitting upon receiving the token frame that are circulating around the network for a specified amount of time. The token frame allows nodes to access the network one at a time, giving 'fair' chance to all nodes to transmit, instead of competing with one another. Message with highest priority has the highest priority to transmit. The token frame method provides high throughput in a bounded latency environment. WCAN is tested in a simulation environment and is found outperforms IEEE 802.11 in a ring network environment in terms of network scalability and high data rate.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117317211","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 the experiments, Gaussian mixture model with different number of mixtures is used as classifier. Different experiments were conducted using all alphabets of Arabic for speaker recognition systems.

Besides these generous peers, there are some other peers who always try to harm the network by providing harmful data or just block the activities with invalid responses and dropping lookup queries to fail the searches by the source peers. These problems force the researchers to introduce trust system into the peer-to-peer networks to isolate the malicious nodes from the generous nodes. In this paper, we have evaluated the effects of malicious nodes in the network by running the simulation of GIA (GIAnduia: an unstructured P2P network, creates the overlay network based on nodes capacities) using OverSim and found out that how we can improve the performance of P2P systems by creating the network based on trust -- based topologies.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115502445","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}

Thus there were several studies about formant frequencies which have been done for adults so far, but still look into the formant frequencies of Malay vowels produced by Malay children have not been well-established. The need to investigate on the effect of age and gender on formant frequency values on children is also obvious. The 360 normal Malay children in 6 different age groups were asked to pronounce all 6 Malay vowels in 5 seconds. The first four formant frequencies of all 6 Malay sustained vowels were extracted for each children in all age groups and the regression line, Mean and Standard Deviation of them were calculated. The results showed that generally Malay children females had higher formant frequency than their male counterparts. The trend reduced during the age growing up.

However, LED has radiation angle that is relatively smaller than other types of lighting device. This results in heterogeneity of light intensity that received by particular point near the LED. To obtain homogeneity of light intensity, this paper proposes a model of fuzzy logic control system to control illumination of LEDs lamp in a room. This model involves several components, namely LEDs lamp, LED driver, illumination sensor, microcontroller, and a differential transceiver RS-485. The fuzzy logic control system that used in this model uses error of illumination and delta error of illumination as input parameter. As output, this control system will change duty cycle of Pulse Width Modulation (PWM) that used to control illumination of LEDs lamp. Based on experiment result, when expected light intensity is set to 150 Lux, homogeneity of light intensity can be achieved with error less than 2%. In addition, the control system also can reduce energy consumption up to 40% under the experimental environment.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117238331","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 major contribution of this paper is the proposal for automating the above procedure for the ASIC implementation of wave-pipelined circuits using built in self test approach. This is studied by a multiplier using dedicated AND gate by adopting three different schemes: wave-pipelining, pipelining and non-pipelining. From the implementation results, it is verified that the wavepipelined multipliers are faster by a factor of 1.08 compared to the non-pipelined multipliers. The wavepipelined multiplier dissipates less power in the factor of 1.43 compared to the pipelined multiplier.","PeriodicalId":200002,"journal":{"name":"2012 Third International Conference on Intelligent Systems Modelling and Simulation","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121548743","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 result is a rooted AVL tree. The n leafs correspond to input data-items that need to n/2 or n/2+1 steps to merge into one cluster, correspond to groupings of items in coarser granularities climbing towards the root. As observed from the time complexity and number of steps needed to cluster all data points into one cluster perspective, the performance of the bi-directional agglomerative algorithm using tree data structure is better than the current agglomerative algorithms.
