Amongst candidate bands to be allocated for IMT-2020 mid bands, the extended C-band (±3.5 GHz) becomes favorite due to its advantages in terms of both technology and economy. Thus, many countries identify it as one of the candidate bands for IMT-2020. In Indonesia, C-Band and extended C-band are primarily occupied by Fixed-Satellite Services (FSS) because of its robustness to heavy rain. This study investigates the feasibility for IMT-2020 and FSS systems to coexist in the extended-C band by analyzing the possibility of interference from IMT-2020 base stations to FSS earth stations using deterministic calculations. The calculations use FSS earth station and IMT-2020 base station trial parameters in Indonesia. The study results show that under any circumstances, co-channel scenario is very challenging since it requires very significant separation distance between the two systems. By employing off-axis angle of 50°, IMT 2020 base station need to be separated at least 78 km away from any FSS earth station. On the contrary, in the adjacent channel scenario, two systems are possible to coexist with a small protection distance (about 1 km) and a guard band of 10 MHz. The protection distance can be minimized by directing the IMT-2020 base station transmitting antenna away from the direction of the FSS earth station antenna.","PeriodicalId":345220,"journal":{"name":"2019 IEEE 4th International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128560220","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}

Also, some CNNs incorporate channel attention mechanisms that re-scale each channel of intermediate feature maps based on their importance. The channel attention modules squeeze the spatial information of a feature into a representative value to transform it as a re-scaling value. In order to reduce the amount of information, attention modules have utilized hand-designed pooling functions such as max pooling or average pooling which have been widely adopted in CNNs, because they add negligible computational complexity. However, a significant amount of spatial information is lost due to these pooling functions. In this paper, we propose a generalized pooling function that scales down spatial information with respect to the importance of each pixel. Unlike max pooling or average pooling, our score-based aggregation is capable of flexibly adjusting to input. Also, the score-based aggregation function learns how to squeeze the spatial information into the must appropriate representative value, which will convert the pooling into a spatial attention mechanism. Finally, we propose a novel method called Score-based Aggregated Attention Module (SAAM) that utilizes the proposed score-based aggregation. Our experimental results on CIFAR-10 and CIFAR-100 datasets demonstrate that SAAM achieves the highest classification accuracy improvement among existing channel attention modules since the score-based aggregation in SAAM is a more dynamic and effective method than the hand-designed aggregations.","PeriodicalId":345220,"journal":{"name":"2019 IEEE 4th International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128567142","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}

On the other hand, it has introduced a new reliability problem called row-hammering, in which, in case that a certain row is activated too frequently, one or more bits in the adjacent rows are unintentionally corrupted. It is crucial to address row-hammering errors because they not only can be exploited by a malicious attack for modern computing systems but also may occur in general applications stored in a highly scaled-down DRAM. Even if several methods have been proposed to resolve row-hammering, existing solutions have limited capability to prevent row-hammering from occurring. Hence, a more robust solution for row-hammering is necessary. In this paper, we propose a novel row-hammering mitigation mechanism, called Adaptive-probabilistic Additional Row Refresh (AARR). The main observation exploited by the proposed method is that each memory access does not have an equal degree of threat to cause row-hammering: accessing a row that has been frequently activated is much vulnerable to row-hammering rather than a barely activated row. In AARR, a small table and a few logic blocks are added to keep track of the threat level that causes row-hammering. Then, one of the adjacent rows of an accessed row is refreshed with an adaptive probability that corresponds to the threat level of that memory access. Our evaluation results show that the proposed method renders the most reliable protection against row-hammering with the lowest overhead on performance and energy compared to two well-known existing solutions.","PeriodicalId":345220,"journal":{"name":"2019 IEEE 4th International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128180682","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 paper discusses a microgrid testbed simulation consisting of one synchronous generator, two induction generators, three induction motors, busbar, and load. The induction motor is used as prime mover which controlled by inverter. The operation of microgrid testbed, both in stand-alone as well as parallel operation, can affect frequency. The speed of prime mover is used to maintain the frequency of the system at 50 Hz (±1 %). The method used to control the speed of prime mover is by changing the frequency of the power source. The best stand-alone operation frequency (50 Hz) of induction generator is achieved by setting the power source frequency to 46 Hz to get the motor speed of 0.85 pu, while synchronous generator operation achieved with setting the power source frequency to 45 Hz and the motor speed of 0.9 pu. The oscillation occurred shortly when induction generator 1 and 2 connected to the system in parallel operation. This happens because the induction generator not only acts as an active power supply, but also absorbs reactive power from the system, so it affects the changes of frequency. The synchronous generator as the primary generator can reduce oscillation because it acts as both active and reactive power supply to the system, so it can stabilize the frequency.","PeriodicalId":345220,"journal":{"name":"2019 IEEE 4th International Conference on Technology, Informatics, Management, Engineering & Environment (TIME-E)","volume":"131 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127186139","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 quality of the image plays a vital role in increasing the success rate of image recognition and related fields. Image quality can be degraded due to distortion, imperfection during image capture, inappropriate light balancing, and exposure to name a few. Various deblurring techniques were introduced to address blurred issues, transforming an image to lesser imperfections, successfully reading and/or identifying available details on it. This study aims to identify, define, and evaluate deblurring techniques in a way that demonstrates comprehension of the tradeoffs involved in the design. Significantly, the study compares various techniques that can be used to recover hidden details in the presence of image noise. The MA TLAB was used as a tool for testing and evaluating the deblurring techniques. PSNR, MSE, and computational time were used to compare each identified deblurring techniques. Based on the comparative performance results of each technique, in terms of accuracy measure, Lucy-Richardson got the highest PSNR ratio of 25.8312 that leads the best result while wiener filter got the lowest PSNR ratio of 21.3012.
