Renjini","doi":"10.1109/ICCPCT.2015.7159416","DOIUrl":"https://doi.org/10.1109/ICCPCT.2015.7159416","url":null,"abstract":"This paper introduces average current mode control of flyback rectifier with bidirectional switch. The proposed control scheme employs an outer voltage feedback loop, which maintains the output voltage as constant and an inner loop, which sense the input current. Average current mode control of flyback rectifier is suitable for obtaining a regulated output voltage with a varying input. Voltage equivalent of input current is averaged by using high gain current error amplifier, which again compared with the reference voltage. Reference voltage is produced by multiplying the rectified input voltage with the error output voltage. Gating pulse is generated by using this signal. This control method obtain better line and load regulation with the addition of inner current loop compared with voltage mode control. Also the rectified input voltage feedback achieves better input power factor. Conventional flyback rectifier is the inter connection of a diode bridge rectifier in the input side and a flyback converter. In order to obtain a highly efficient flyback rectifier with fewer losses an improved flyback rectifier is introduced. Here, two switches are connected in back to back to establish the bidirectional switch element, which will conduct both in the positive and negative half cycle of the ac input voltage. The transformer with dual output windings with a diode in each winding reduces the current stress across each diode. New topology adds an extra switch in the primary side and a diode in the secondary side. Improved bridgeless flyback rectifier only introduces a switch with common gate drive, a diode and an additional winding in the secondary side. Thus the weight of the converter is not affected with these additional components. Proposed average current mode control can be used as an adapter. Design and simulated waveforms are added in this paper for an output rating of 20V/1.5A.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"13 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2015-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86371219","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 Proposed method has been used to segment normal tissues and abnormal tissue like tumor part of MR image automatically. MR images are often corrupted by Intensity in homogeneity and artifacts. This may affect the performance of image processing techniques used for brain image analysis. Due to this type of artifacts and noises unknowingly some normal tissue in MRI may be misclassified as other type of normal tissue and it leads to error during diagnosis process. The proposed system remove noise from the given images using a method called spectral subtraction de noising (SSD) and Kernel Weighted Fuzzy C Means (KWFCM) has been used for segmentation. This method incorporates spatial information and the membership weighting of every cluster has been altered after the cluster distribution in the neighborhood is considered.

The pin based security is the simplest level of security. The pin number is a unique number which is encrypted and decrypted during transaction. Nowadays the pin number can be extracted through many ways, for fraudulent activity. So, as a solution the pin number can be replaced with biometric security. The biometric security may be fingerprint, retina and so on. Nowadays, the system is used to compare the input image with the image in the database and if they are verified, the bank staff would disperse the cash. But the proposal model would completely replace the pin number with biometric system and the machine would disperse the cash when the comparison gets satisfied.

The performance characteristics of different forecasting models have been compared by applying different measure of errors such as bias, mean absolute error, root mean square error and standard deviation.

Srivastava","doi":"10.1109/ICCPCT.2015.7159390","DOIUrl":"https://doi.org/10.1109/ICCPCT.2015.7159390","url":null,"abstract":"The nanometre technology is different fundamentally from its predecessors as it is exposed to a wide variety of new effects that are induced on the transistor chips. NBTI is one degradation effects in the reliability regime. It plays significant role as it leads to severe performance degradation. Ageing in pMOS transistor takes place due to Negative bias temperature instability (NBTI) which is the major threat to reliability as we scale down the transistor geometries consistently towards our objective for less power consumption coupled with high performance. The work presented in this paper focuses on NBTI detection scheme for building tolerance with respect to NBTI effects employing Adaptive Body Bias (ABB). In this scheme, an On-Chip monitor detects the change in threshold voltage of the circuit to generate corresponding adaptive body bias by the body biasing circuit which is supplied to the transistors. The simulations have been carried out taking VBB as zero, i.e., No Body Bias (NBB), by applying a finite adaptive body bias (ABB) voltage to the transistors on the chip & their corresponding power and delay have thus been calculated by implementation of the proposed approach on a host of domino logic circuits which include Current comparison domino (CCD). We have mitigated the rise in delay problem by suitably allocating a supply voltage so that the delay specifications are continuously met even after a time span of 10 years of operation at the cost of very low power headroom. Simulations have been performed using the BSIM4v4.7 model & 32-nm predictive technology model in SILVACO EDA tool at a frequency of 2 GHz and nominal supply voltage of 0.9V. The proposed approach has been implemented on 32-bit & 64-bit OR gates and also on 32-bit comparator and the results has been noteworthy.","PeriodicalId":6650,"journal":{"name":"2015 International Conference on Circuits, Power and Computing Technologies [ICCPCT-2015]","volume":"30 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2015-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77813574","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}
