And the numerical simulations also reveal that the rapider improving the number of flaws per unit area of the intima, the greater the degree to which the reduction of the volume of the blood vessel in the arteriosclerosis-causing part is suppressed. However, in case for example the cholesterol concentration in blood is high, the effect of suppressing the progression of arteriosclerosis is small.

Two small RC samples’ frontal geometry was considered from a reported experimental study, tested here against corrosion in a chloride environment. Those samples had different rebar diameters (10 mm and 16 mm). The reported specific electrochemical parameters and material properties were selected through this numerical investigation. The cathodic protection system’s optimization process was based on identifying the appropriate external applied potential $E_{app}i$ which lowers at minimum the corrosion rate. In this purpose, the first average corrosion current density iFe under the value with minimum corrosion risk (of 0.1 $mu A/cm^{2}$) was identified for both models. For Model 1 with rebar diameter of 10 mm, a safe iFe value of 0.087 $mu A/cm^{2}$ was attained $E_{app}i=-0.225V$, and for Model 2 with rebar diameter of16 mm, $i_{Fe}=0.085mu A/cm^{2}$ at $E_{app}i=-0.15$ V.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128627839","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 goal of the study is to explore a novel procedure to detect the shear rates domain where possible wall depletion might be present. The measurements are performed in simple shear with the Anton-Paar MC301 rotational rheometer, the samples (xantan solution and grease) being located between a smooth plate and a special manufactured lower plate patterned with pillars. The rheological behavior of the samples in the tested configurations are characterized by two material functions: (i) the flow curve $sigma(dot{gamma})$ and (ii) the differential viscosity $boldsymbol{eta}_{d}=boldsymbol{d} sigma / boldsymbol{d} dot{gamma}$, where $sigma$ is the shear stress and $dot{gamma}$ is the shear rate. The experimental data put in evidence an instability region, which is related to the plateau of the flow curve and possible apparent slip at the walls. The existence of the yield stress is also discussed.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129069799","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}

At the same time, it must be conform to the legal regulations and norms. When a photovoltaic installation is to be delivered into the power supply network, its operating parameters must be closely monitored. In this work we present the results of our monitoring of a low power photovoltaic installation. Upon examination of the voltage variations, of the currents, of the voltage and current harmonics, we conclude that the installation we studied does indeed fulfill the necessary requirements for connecting to the national power grid. Examining the energy levels consumed by the beneficiary, we find that the photovoltaic installation cannot continuously ensure the required energy levels, which recommends the acquisition of an additional photovoltaic installation.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130289178","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 computation was performed at steady state for a cable joint insulation consisting of Ethylene Propylene Rubber (EPR) installed for a cable with Cross-linked Polyethylene (XLPE) insulation. The presence of the FGM layer leads to important modifications of the electric field values, especially near the corners of the cable joint inner semiconductive layer. The results also show that the maximum electric field and temperature values, as well as the surface charge density values present at the interface between the insulations are lowered by using a FGM layer. This leads to reduced electric stresses and charge injection. The reduction of the surface charge density values also reduces the values of the residual electric field and leads to a slowdown of insulation ageing.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123238527","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}

Calculations and graphs, performed for both an array with a square planar aperture and an array with a circular planar aperture, show that, at similar results (opening, gain), there are at least two net advantages of the circular planar array respectively, the number of antenna elements is lower (which implies a lower cost price) and lower levels of side lobes to the patterns.","PeriodicalId":359645,"journal":{"name":"2021 12th International Symposium on Advanced Topics in Electrical Engineering (ATEE)","volume":"68 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114103427","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 efficiency has been demonstrated by testing the device while walking and having as object a container with liquid. The purpose of the study is to minimize the costs of making such platforms and their widespread use in various fields (e.g. cup holder that can be mounted on car dashboard).
