Fuzzy subtractive clustering (FSC) with exponential membership function for heart failure disease clustering

The fuzzy clustering algorithm is a partition method that assigns objects from a data set to a cluster by marking the average location. Furthermore, Fuzzy Subtractive Clustering (FSC) with hamming distance and exponential membership function is used to analyze the cluster center of a data point. The data point with the highest density will be the cluster's center. Therefore, this research aims to determine the number of collections with the best quality by comparing the Partition Coefficient (PC) values for each number produced. The data set, which is heart failure patient data, is 150 data obtained from UCI Machine Learning. The data consists of 11 variables, including age

Shortest Route at Dynamic Location with Node Combination-Dijkstra Algorithm

Abstract— Online transportation has become a basic requirement of the general public in support of all activities to go to work, school or vacation to the sights. Public transportation services compete to provide the best service so that consumers feel comfortable using the services offered, so that all activities are noticed, one of them is the search for the shortest route in picking the buyer or delivering to the destination. Node Combination method can minimize memory usage and this methode is more optimal when compared to A* and Ant Colony in the shortest route search like Dijkstra algorithm, but can’t store the history node that has been passed. Therefore, using node combination algorithm is very good in searching the shortest distance is not the shortest route. This paper is structured to modify the node combination algorithm to solve the problem of finding the shortest route at the dynamic location obtained from the transport fleet by displaying the nodes that have the shortest distance and will be implemented in the geographic information system in the form of map to facilitate the use of the system. Keywords— Shortest Path, Algorithm Dijkstra, Node Combination, Dynamic Location (key words

Short-term forecasting of the electric demand of HVAC systems

Heating, Ventilation and Air Conditioning (HVAC) systems of large buildings have a high contribution to the electric grid peak demand. During those periods, electric utilities face important mismatch issues in power supply and demand. In the context of Demand Response (DR) programs, there is a need from building energy managers for tools to forecast the electric demand of HVAC systems to plan for fast-DR control strategies. This thesis contributes to the DR research field by proposing a method for multi-step forecasting of the electric demand of existing HVAC cooling systems on the short-term in large commercial and institutional buildings. Two forecasting methods are proposed: a cascade-based (global) method and a component-based method. The cascade-based method includes a sequence of forecasts of target variables. First, the air flow rate supplied by the AHUs is forecasted, followed by the cooling coils load, the cooling load of the whole building, and finally the electric demand of the primary cooling system is forecasted. The component-based method forecasts the electric demand of one component of the HVAC system such as a fan. Data-driven models are developed based on Building Automation System (BAS) trend data for electric demand forecasting of HVAC cooling system over the next six hours with a time-step of 15 minutes. The large amount of data collected through the BAS presents a gold mine of information which could be used for better understanding of the actual building operation and performance. Data mining techniques are used as pre-processing steps to help in the development of the forecasting models, for the selection of regressors, to identify typical daily profiles of the target variable and to better understand the operation of HVAC systems. Different sequences of preprocessing steps are tested and their impact on the forecasting performance is compared. The proposed forecasting methods are validated on two case studies: the Genomic research center on Loyola Campus of Concordia University and an office building located in Shawinigan-Sud (Québec). The thesis compares the forecasts with measurements, and discusses the quality of forecasting results

Crab and cockle shells as heterogeneous catalysts in the production of biodiesel

In the present study, the waste crab and cockle shells were utilized as source of calcium oxide to transesterify palm olein into methyl esters (biodiesel). Characterization results revealed that the main component of the shells are calcium carbonate which transformed into calcium oxide upon activated above 700 °C for 2 h. Parametric studies have been investigated and optimal conditions were found to be catalyst amount, 5 wt.% and methanol/oil mass ratio, 0.5:1. The waste catalysts perform equally well as laboratory CaO, thus creating another low-cost catalyst source for producing biodiesel. Reusability results confirmed that the prepared catalyst is able to be reemployed up to five times. Statistical analysis has been performed using a Central Composite Design to evaluate the contribution and performance of the parameters on biodiesel purity

Molecular phylogeny of horseshoe crab using mitochondrial Cox1 gene as a benchmark sequence

An effort to assess the utility of 650 bp Cytochrome C oxidase subunit I (DNA barcode) gene in delineating the members horseshoe crabs (Family: xiphosura) with closely related sister taxa was made. A total of 33 sequences were extracted from National Center for Biotechnological Information (NCBI) which include horseshoe crabs, beetles, common crabs and scorpion sequences. Constructed phylogram showed beetles are closely related with horseshoe crabs than common crabs. Scorpion spp were distantly related to xiphosurans. Phylogram and observed genetic distance (GD) date were also revealed that Limulus polyphemus was closely related with Tachypleus tridentatus than with T.gigas. Carcinoscorpius rotundicauda was distantly related with L.polyphemus. The observed mean Genetic Distance (GD) value was higher in 3rd codon position in all the selected group of organisms. Among the horseshoe crabs high GC content was observed in L.polyphemus (38.32%) and lowest was observed in T.tridentatus (32.35%). We conclude that COI sequencing (barcoding) could be used in identifying and delineating evolutionary relatedness with closely related specie
