This makes ARX ciphers especially fast in software implementations, but comes at the cost of making it harder to protect against side-channel information leakages using Boolean masking: the best known 2-shares masked adder for ARM Thumb micro-controllers takes 83 instructions to add two 32-bit numbers together. Our approach is to operate in bitsliced mode, performing 32 additions in parallel on a 32-bit microcontroller. We show that, even after taking into account the cost of bitslicing before and after the encryption, it is possible to achieve a higher throughput on the tested ciphers (CRAX and ChaCha20) when operating in bitsliced mode. Furthermore, we prove that no first-order information leakage is happening in either simulated power traces and power traces acquired from real hardware, after sufficient countermeasures are put into place to guard against pipeline leakages.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126855462","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 work proposes the design of a positioning system based on trilateration. The main objective is to predict the positioning in both the ‘x’ and ‘y’ axis in an area of 8 square meters. For this purpose, 3 Access Points (AP) and a Mobile Device (DM), which works as a raster, have been used. The Received Signal Strength Indication (RSSI) values measured at each AP are the variables used in regression algorithms that predict the x and y position. In this work, 24 regression algorithms have been evaluated, of which the lowest errors obtained are 70.322 [cm] and 30.1508 [cm], for the x and y axes, respectively.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124998287","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}

Light distribution is measured in the way that luminaire changes its position, respectively angle towards to luxmeter which measures light intensity in defined angle. The proposed automated system is used for the control of two motors which are used for positioning the luminaire. The proposed system is used also for automated measuring of luminous intensity at defined angles which can be defined by the user. This can speed up measurement significantly because, if the luminaire is symmetrical so only half of the measurement samples are necessary. The next advantage of the proposed system is that all results of measurements are saved in EULUMDAT which except for values of luminous intensity contains parameters of luminaire and parameters of measurement. Files in this format can be processed directly in some special software for lighting design.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130845629","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}

Traditionally, the NSAF has made use of sophisticated perfect reconstruction (PR) filter banks and a block updating scheme, in which the adaptive filter vector is updated once every N samples, with N being equal to the number of subbands. Here we argue, first from a theoretical point of view, that an extremely simple two band filter bank with the simplest possible length 2 FIR filters, {1, −1} and {1, 1}, can be successfully used either with a sample by sample adaptive filter update, or with a block update performed for every second input signal sample. We demonstrate that this scheme actually works well through simulations. In short we obtain better convergence performance than the NLMS with a (multiplicative) computationally complexity proportional to 2M, M being the length of the adaptive filter to be identified, with the block update and even better performance if we are willing to accept a computational complexity proportional to 4M.","PeriodicalId":113076,"journal":{"name":"2022 International Conference on Applied Electronics (AE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124846577","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}

Furthermore, the LC equivalent circuit and transfer function of funnel shaped resonator are extracted. The cut-off frequency of proposed filter at −3 dB is 1.4 GHz and this filter has an ultra-wide stopband begins from 1.66 GHz to 17 GHz with the suppression level of 20 dB. Moreover, this lowpass filter has a sharp transition band of 0.26 GHz and compact size of 0.138 λg ×0.05 λg.
