Approximation is done to reduce the high consumption of area and power at the cost of accuracy. An array-based approximate arithmetic computing model (AAAC) is used for the reduction of error occurring in approximate binary arithmetic circuits. Although the model provides a trade-off between power, area and accuracy, these parameters can be improved further. The proposed model in this paper uses reduced number of truncated bits and a different compressor architecture for this improvement. An approximate $16 times 16$ booth multiplier and an approximate 16 bit squarer are used as the applications. The proposed model for squarers reduce the power and area by 8.4% and 21.5% respectively and has an accuracy improvement of 3.4% when compared to the existing model. Similarly the proposed model for booth multiplier reduces the power and area by 4.5% and 3% respectively and has an accuracy improvement of 3.2% when compared with the existing one.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114891717","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}

Individuals experiencing foot pathologies often require the use of assistive or corrective devices such as prosthetics or orthotics. A conceptual remedial orthotic device is modelled in this study to alleviate the foot conditions in which heel-strike phase is absent. The CAD model of this orthotic model was loaded using a finite element tool to study its mechanical behaviour under the loading conditions that a human foot sustains during the various phases of healthy gait. The von-Mises stress distributions are studied using loading conditions obtained from gait analysis results and those from statistical models. The viability and prospects of using these methods in rehabilitation engineering are discussed in this research.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123222539","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 decoupler is designed using inverted decoupling technique. As there are three unknown parameters of the FOPI controller, we have used phase margin, gain crossover frequency and velocity error constant specifications to get a objective function and constraints for optimization based control design approach. After obtaining the objective function, the optimization problem is solved by Grey Wolf Optimization (GWO) algorithm. To show the effectiveness of the approach of designing an FOPI controller for the decoupled process with respect to PI, both simulation and real-time analysis is done. It is observed that the design approach is simple and easy to implement in real-time environment.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"193 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122123184","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 this technique, genes with same expression values are discovered across some fragment of time points, under certain conditions. In this paper, triclustering using evolutionary algorithm is implemented using a new fitness function consisting of 3D Mean Square residue (MSR) and Least Square approximation (LSL). The primary objective is to find triclusters with minimum overlapping, low MSR, low LSL and covering almost every element of expression matrix, thus minimizing the overall fitness value. To improve the results of algorithm, new fitness function is introduced to find good quality triclusters. It is observed from experiments that, triclustering using EA yielded good quality triclusters.

It enables transfer of electric power from one coil to the other based on the principle of electromagnetic induction. Inductive coupling (IC) and magnetic resonance coupling (MRC) are the two main methods of WPT. In this paper, MRC technique is used to effectively transfer power over large air gaps. Low power transfer efficiency (PTE) is the major challenge in WPT charged EVs. This may causes due to misalignment between the transmitter (Tx) and the receiver (Rx) coils. Lateral and angular are two commonly occurring misalignments in the practical scenario of WPTS. This paper presents the simulation analysis of various factors, which effects PTE. In the analysis, the lateral misalignments are performed for distinct airgaps between Tx and Rx. Various modes of angular misalignments are presented for a fixed value of airgap between coils. In addition, the paper provides the effect of various cores and aluminum shielding on PTE for distinct air gaps are documented.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124501495","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}

It deals with the separation of annular iris from the acquired eye image. Accuracy of the iris segmentation module directly affects the overall system accuracy. In order to localize the pupillary boundary, this work utilizes local binary pattern (LBP) to exploit the uniform intensities present in the pupil region, to detect its boundaries. LBP aids in reducing the adverse effects of eyelashes in pupil localization. Moreover, an adaptive mask is also developed for localizing the limbus boundary. This mask provides a mean to combat with the varying sizes of iris due to variation in illumination. Outcomes of experiments performed with two benchmark iris databases (i.e. CASIA-IrisV1 and IITD iris database) support the efficacy of the proposed approach.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124817499","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}

Due to high cost constraint of PMU, the proposed OPD approach is carried out in several phases. The ability to determine possible multiple outputs (MOs) by the proposed algorithm can also provide multiple observability choices and selection of the best desired output from the MOs is very crucial. To select the best solution from the MOs, maximum redundant observability (MOR) is developed in this paper. Two new mathematical equations are adopted for the prioritization of generator and weaker buses during the initial and mid phases. Such mathematical models not only help to prefer those buses for PMU deployment but also improve their measurement reliability. The proposed phase OPD approach is applied on IEEE 57-bus test system and to verify the efficiency of the proposed BSFLA, its performance is compared with other optimization algorithms.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128170321","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}

Biclustering of microarray data is an efficient data mining technique to gain knowledge regarding the functional behaviour of multiple genes under a set of experimental states. In this work, sequential GA using weighted sum approach is first implemented to derive good quality biclusters. The multiple objective functions are mapped to single objective function using weighted sum approach; however, the primary challenge lies in deriving the accurate weight values. To overcome this drawback of sequential GA, NSGA-II is adopted for solving multiobjective optimization problem.

Therefore, controller's design, for controlling the pendulum angle, is an ambitious and fascinating task for control designer to handle such complexities present in the system. In this paper, the interval type-2 fuzzy proportional derivative plus integral $(mathrm{IT}2mathrm{FPD}+mathrm{I})$ is incorporated with fractional order PID (FOPID) controller and resulting new interval type-2 fractional order fuzzy $mathrm{PD}+mathrm{I}(mathrm{IT}2mathrm{FO}-mathrm{FPD}+mathrm{I})$ controller is presented for inverted pendulum system to suspend pendulum in the vertical on cart. For the optimal controller design, the recent artificial bee colony (ABC) optimization technique is applied to achieve optimal controller parameters. Furthermore, to show the effectiveness of presented control approach, the inverted pendulum system is also tested in presence of disturbance, random noise rejection, and parameter variations. Eventually, the results clearly show that the performances of $mathrm{IT}2mathrm{FO}-mathrm{FPD}+mathrm{I}$ is superior to type-1 fractional order fuzzy $mathrm{PD} +mathrm{I}$ controller $(mathrm{T}1mathrm{FO}-mathrm{FPD}+mathrm{I}), mathrm{T}1mathrm{FPD}+mathrm{I}$, and PID controllers.","PeriodicalId":263943,"journal":{"name":"2017 14th IEEE India Council International Conference (INDICON)","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127184612","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}
