This includes the use of a Programmable Logic Controller (PLC) as the main controller and the Variable Frequency Drive (VFD) as the motor's inverter drive. Combination of ladder logic diagrams (LLD), structured texts (ST) and function block diagrams (FBD) were used to code the fuzzy program. The FLC was built with 36 rules from the two (2) inputs, Actual Error or Δ Speed and Actual Error Rate or Rate of Δ Speed, having six (6) membership functions each: Neg_Large, Neg_Medium, Neg_Small, Pos_Small, Pos_Medium and Pos_Large. Mini-fuzzy associative matrix (FAM) was also introduced in the study to reduce the number of computational rules by 75%. Center of gravity (COG) was the defuzzification technique used to convert the fuzzy outputs into crisp real data due to the simplicity of its computation in providing fast results. The proposed fuzzy controller was based from the data feedback value of the drive to attain the desired motor speed. The controller was able to consider the effect of different load variations in different loadings.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115140785","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 adapted speech recognition architecture was that of the Oregon Graduate Institute's (OGI) Center for Spoken Language and Learning (CSLU). It utilizes a hybrid Hidden Markov Model/ Artificial Neural Network (HMM/ANN) keyword spotting framework. The feature extraction method used was Mel-Frequency Cepstral Coefficients (MFCC). The ANN is a 3-layer feedforward neural network using Multi-Layer Perceptron (MLP). In recognizing the words, an HMM decoder was used which implemented the Viterbi Beam Search Algorithm. Whenever a profane word was recognized, it would be replaced with a constant frequency tone. The training and testing data (recordings) were gathered from 30 random (15 male and 15 female) Filipino speakers.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133263529","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}

Molecular Dynamics simulations using GROMACS software were utilized to obtain a molecular model of a cell membrane. The membrane model was composed of 32 dilauroylphosphatidylcholine (DLPC) lipids, 32 dioleolyphosphatidylcholine (DOPC) lipids, 32 dipalmitoylphosphatidylcholine (DPPC) lipids, 32 distearoylphosphatidylcholine (DSPC) lipids and 6000 water molecules in an all-atom force field. The effect of varying the temperature on the bilayer thickness and the effect of varying the osmotic pressure on the water migration across the lipid bilayer were determined. The temperature was varied from 300 K to 345 K with 5 K interval and the pressure was changed from 100 MPa to 150 MPa with 10 MPa interval. Results showed that at increasing temperature the bilayer thickness increased but when it reached 340 K the bilayer thickness started thinning. Furthermore, at increasing osmotic pressure the water migration became faster.","PeriodicalId":309548,"journal":{"name":"2014 International Conference on Humanoid, Nanotechnology, Information Technology, Communication and Control, Environment and Management (HNICEM)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121131143","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}
