Unlike stationary energy storage units, mobile energy storage can move between different buses by truck to provide different local services within the distribution feeder. This work proposes a day-ahead energy management system (EMS) for a MESS that aims to minimize the cost of the power imported from the grid. The MESS does not only shift renewable energy power to load peak-hours but also can provide localized reactive power support. Given the day-ahead predictions, the EMS decided the optimal MESS stations in the feeder and the operating power. The applicability of the proposed scheduling and operation algorithms is tested on a typical 41-bus radial feeder.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123031792","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}

Until now Apple published many iterations of their operating system and with that introduced many new features that are related to system security. Even though security-related changes go unnoticed, in the world of digital forensics this presents a challenge. Today encryption can be implemented on both, hardware and software level, which can make imaging Mac OS difficult. Besides, security which is meant to protect, user data is also used by criminals to restrict access to their computers. This paper will focus on the differences and problems that occur while creating a forensic image and extracting data from Mac OS.

The relevance of BiNRs for logic device applications at the nanoscale is further analyzed by studying the width-dependence of the ON and OFF state conductance and their ratio that reaches $sim 10^{7}$ in 1.1 nm-wide BiNRs.

A low-cost open source NodeMCU hardware and firmware platform based on ESPS266 is used, that provides WiFi connectivity and Lua interpreter as programming language. Raspberry Pi is used as a central hub for IoT devices. Teachers build an IoT system for monitoring indoor temperature and humidity, outdoor temperature and controlling an air-conditioner using IR control.

In this paper, a realization of a system for CS of analog one-dimensional signals in a shift-invariant subspace is proposed. We use statistical compressive sensing that allows efficient sampling of signals that follow some statistical distribution. In fact, principal component analysis is used to obtain a small number of principal components in which the majority of signal’s energy is compacted. The signal is demodulated using the obtained principal components, which provides optimal measurement procedure in the mean-square error sense. Orthonormality allows for a linear reconstruction which is perfectly suited for a real-time embedded system implementation. Due to hardware realization constraints, the adaptive demodulating signal is quantized. We provide qualitative and quantitative validations based on simulations of the proposed CS system realization. Furthermore, we validate performance of the system when additive white Gaussian noise is present in the measurements.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129794835","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, with the rise in popularity of neural networks, the research in the recent years focuses mainly on deep learning approaches. We test the accuracy and maintainability of both types of classifiers and try to test a new vector distance approach using a custom distance metric to see if there could still be room for improvement in the field of more traditional systems for keystroke-based authentication. We also test a keystroke dynamics and face recognition fusion classifier to see if a multi-modal system is perhaps the best compromise in terms of maintainability and performance. We find that there is still room for research on more traditional keystroke rhythm comparison techniques and conclude that by fusing those together with a face recognition pipeline we can achieve very good results in web authentication systems.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124665977","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 process consists in selecting one or more chemical compounds with the highest binding free energy to target proteins. Given that the empirical space of chemical compounds is extremely large and estimated to has over 50 millions of them, finding the most effective drug is computationally challenging. Furthermore, the vast majority of proteins still lack the experimentally obtained 3D structures, making it hard to accurately calculate their binding free energies with chemical compounds. With this in mind, the aim of our study was to investigate the accuracy of the Autodock Vina program in a virtual drug screening on a set of proteins that do not have experimentally determined structures. To do this, we performed a virtual drug screening with the Autodock Vina on a large set of drug-kinase pairs taken from the IDG-Dream Drug-Kinase Binding Prediction Challenge. The results obtained show that the Autodock Vina can be used effectively in such unstructured environments.","PeriodicalId":437575,"journal":{"name":"2020 43rd International Convention on Information, Communication and Electronic Technology (MIPRO)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129910188","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}
