Two types of binary hybrid composite were studied. In one, the surface of pristine TiO2 nanoflowers was modified by noble metal catalyst Pd (Pd-TNFs). Whereas, for the other case, the surface of the pristine structure was decorated by 2D material rGO (rGO-TNFs). To authenticate, the structural and morphological properties of the hybrid structure, the following characterizations viz. FESEM, XRD and Raman spectroscopy were performed. Methanol and ethanol were used here as the test VOCs in the concentration range of 10-700 ppm for the hybrid sensor devices. The sensing performance was studied in the temperature range of $27^{circ}mathrm{C}-180^{circ}mathrm{C}$ and the corresponding transient characteristics of the hybrid devices were given at optimum temperature only. It was revealed from the above study that in between ethanol and methanol, the sensing performance in terms of response magnitude was promising towards ethanol compared to methanol, for these hybrid devices. Moreover, the methanol sensing performance was significantly improved in these hybrid structures compared to its pristine TiO2 nanoflowers counterpart due to the surface modification techniques.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123174188","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 platform considers the mutual combination of the multi-physics subsystems, which enables to optimize the total robot-power efficiency. We focus on the joint interactions between electrical and mechanical domains (example: electro-mechanical interaction in a servo motor) and the resulting power loss. As an example, the power dissipation of a biped robot for a gait cycle is estimated. Thus platform usability for developing power efficient humanoid robots is demonstrated.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"195 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115964618","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}

Our purpose in this study is to clarify the switching features of the IGBT for developing an accurate compact model, which can predict the switching losses accurately. The main focus is therefore given on the carrier dynamics within the device during switching. It is demonstrated that the ambipolar feature of the bipolar function of IGBT leads to a fast carrier response during the switching. The large amount of the majority-carrier existence realizes this rapid reaction of the carrier dynamics in response to the switching condition.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115260847","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}

However, anyone can easily edit or manipulate any digital image on a computer. Thus, an effective method for detecting digital image manipulation is required for retaining authenticity. Image-manipulation detection is applied in investigations of crimes and photographic evidence. In this paper, we describe a technique for detecting a manipulated image by morphological pattern spectrum. Before we have researched morphological pattern spectrum detected manipulation. We propose the new technique which counts a number of the same scale as the structuring element scale by morphological pattern spectrum in an image. So it can judge a manipulated image in detail because the new technique can detect the number of a manipulated scale. Thus, even if the previous technique judge a large different in the pattern spectrum between the original image and the manipulated image, the new technique can judge to be actually small manipulation.","PeriodicalId":293660,"journal":{"name":"2019 2nd International Symposium on Devices, Circuits and Systems (ISDCS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126105005","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}

State-of-the-art hardware for training and inference of CNN architectures require a considerable amount of computation and memory intensive resources. CNN achieves greater accuracy at the cost of high computational complexity and large power consumption. To optimize the memory requirement, processing speed and power, it is crucial to design more efficient accelerator architecture for CNN computation. In this work, an overlap of spatially adjacent data is exploited in order to parallelize the movement of data. A fast, re-configurable hardware accelerator architecture along with optimized kernel design suitable for a variety of CNN models is proposed.
