Classification and association rule mining are vital to such practical applications. Thus, if these two techniques are somehow integrated would result in great savings and conveniences to the user. Such an integrated framework is called associative classification (AC). This integration is carried out by focusing on a specific subset of association rules whose consequent contains only class attribute. Several studies in data mining have shown that AC is superior to other traditional classification algorithms due to its numerous favorable characteristics such as readability, usability, training efficient and excellent accuracy. Hence, various AC techniques are studied with its pros and cons. However, AC suffers from a drawback that large number of rules is produced as an output. Now, utilizing all these rules for analysis would be computationally expensive. This paper studies various pruning and evaluation methods that are employed to produce qualitative rules. Further, the paper empirically evaluates associative classification technique considering various parameters.","PeriodicalId":306637,"journal":{"name":"2017 Nirma University International Conference on Engineering (NUiCONE)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122694950","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 main drawback of NPC inverter is the fluctuation in the neutral point voltage and the corresponding imbalance created in dc-link capacitor voltages. A balancing scheme is proposed in this paper for five-level NPC inverter by providing offset in the individual carrier without using any extra hardware. In this scheme, only capacitor voltages are measured and not the load current. However, the limitation of this control scheme is that the wave shape of fundamental output voltage of the inverter is not as per the requirement. The output voltage has full dc-link voltage but waveform has only three levels when machine is operated in five-level mode. The quarter wave as well as half wave symmetry in an inverter output voltage is lost so harmonics in the output voltage waveform increases compared to sinusoidal pulse width modulation (SPWM) technique for the same level. The rms output voltage is more than that of an ideal NPC inverter. This will affect V/f ratio as well as torque of the motor. Also, dv/dt stress on switches increases due to less number of levels compared to ideal five-level NPC inverter. Simulation is carried out in MATLAB/Simulink. Hardware implementation of one leg of five-level neutral point clamped inverter with stiff dc power supply for each capacitor is carried out using dSPACE DS1104 controller board. The proposed scheme can be applied (for two-level and three-level modes) in conjunction with other hardware scheme used for balancing during four-level and five-level operation, leading to a hybrid balancing scheme.","PeriodicalId":306637,"journal":{"name":"2017 Nirma University International Conference on Engineering (NUiCONE)","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115021860","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}

This system is mainly used for irrigation purpose in farming and household purposes. In the proposed system, induction motor along with submersible pump of 1.5 kW is used. On the basis of motor rating, solar panel rating is decided to be 1.8 kW considering losses in the system. In this paper the main focus is to design boost-converter which boosts the voltage obtained from solar panel. This boost voltage acts as a dc-link voltage for three-phase inverter. Three-phase inverter is developed to convert dc voltage into ac voltage. This ac voltage generated is given to induction motor which runs the submersible pump. Maximum Power Point Tracking (MPPT) algorithm is implemented to obtain maximum power from the solar panel under different solar irradiation and temperature. In this topology, incremental conductance method is used to obtain maximum power from solar panel. Modulation index of inverter is controlled by Sine-Triangle Pulse Width Modulation (SPWM) technique. SPWM along with V/F scheme is implemented for the control of inverter which results in the control of speed of induction motor when the output from solar panel changes. Design and simulation verification of the system is performed in PSIM software. After satisfactory results obtained through simulation studies, hardware setup is also tested on resistive load.","PeriodicalId":306637,"journal":{"name":"2017 Nirma University International Conference on Engineering (NUiCONE)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129170174","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}

Here the term Cloud comes into existence which provides various services to its user without taking a burden as well as with cheaper cost. This gives much benefits to user but conversely it also suffers from some burning issues like confidentiality, availability, continuous Network connection requirement, integrity and many more. The user data is available on Cloud system and to process that data securely a providers need to process this data without displaying identity of the user. Secondly the user must be able to work with open environment even if the network connection is not available. First issue is solved using the anonymization techniques and for second issue we used an important new term called Dew computing. Dew computing together with Cloud makes a Cloud-Dew architecture which solves above mentioned issues. We are among few researchers who proposed a scheme which solved important issues related to privacy of user information in Cloud-Dew Computing architecture that may be one of the important open platform computing trends in the future.","PeriodicalId":306637,"journal":{"name":"2017 Nirma University International Conference on Engineering (NUiCONE)","volume":"98 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113954431","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 Simultaneous localization and Mapping (SLAM) is a complex process and consumes major chunk of computational power. Many algorithms have been developed to enhance the SLAM process and is a progressing area in Robotics research. ROS is one such framework which provides multiple algorithm nodes to work with and provides a communication layer to Robots. Many of these algorithms majorly in use are HectorSLAM, Gmapping and KartoSLAM. This paper provides with a quantitative analysis of these algorithms and their performance on various parameters on a differential robot equipped with 2D Laser scanner. We Study the optimum parameters of each of these algorithms and then compare the performance of these algorithms against one another.
