The specific topics that were investigated are the brain and its importance in learning, characteristics of the hemispheres of the brain learning and the contribution of neuroscience in the teaching-learning process. The first topic mentions how the brain influences learning and the role of memory in that process. The next topic focuses on the characteristics and functions performed by the two brain hemispheres. The latest content deals with the contribution of neuroscience in the educational field, here is detailed on how neural networks combined with the environment where the student performs to make learning possible. The descriptive methodology, based on the review of current bibliographic sources, was used.

These distribution networks have been planned with wide operating margins, which together with the characteristic that energy flows are unidirectional (from the substation to consumers) allow them to be operated passively. This means that they are not subject to constant monitoring of the network status variables (ie voltages, flows), so these networks are managed with little supervision since that is more economical. The objective of this research is to investigate the economic impact that is presented within the university for a better presetting in the low voltage lines for them, the causes and effects that can be committed when installing them have been investigated, in addition to making a bibliographic review of how in other countries and within our city Portoviejo is distributed in low voltage and its consequences or benefits.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116477343","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 method used is to compare statistically descriptive area and distribution class produced by the NDVI and RVI models with area data from the Forestry and Plantation Service (FPS), Buleleng regency, Bali in 2014, amounting to 7622.32 ha. The estimated area of ??clove vegetation by the NDVI model was 7852.68 ha and the RVI model was 7669.44 ha. There is an estimated difference in the area of ??clove vegetation of 183.24 ha and a difference in the broad class category of 2453.85 ha for the Rare class (NDVI > RVI) category, for the Medium class of 1611.45 ha (RVI > NDVI), and for the Dense class of 659.16 ha (RVI > NDVI). Comparison of the area with FPS data obtained 97.07% for the NDVI model and 99.39% for the RVI model.

The method used is a solid state reaction. The phase formation of the sample Ba1-xLaxFe12O19 was carried out at 1200oC for 2 hours. The results of the X-ray diffraction pattern analysis show that all sample compositions have a single phase BaFe12O19. The results of magnetic properties testing using VSM showed that the best coercivity field and remanent magnetization values were obtained at the composition of x = 0.04. The effect of substitution of lanthanum into the barium atom can increase the number of magnetic domains which are indicated by the increase in the coercivity value of the material along with the increasing composition of x. It was concluded that the composition of Ba1-xLaxFe12O19 is a permanent magnet with the best product energy.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128090914","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}

Simulation methods are used to show how harmonic propagation occurs in the system. MATLAB Simulink is used as a method of simulation with generating harmonics loads and linear loads.

The results showed that after controlling motor educability, football skill learning achievement of the students who learned through the Cooperative Learning type Jigsaw model was higher than those who learned through the conventional model; the football skill learning achievement of those who were assessed by portfolio assessment was better than those who were assessed by authentic assessment. There was also an interaction between the teaching model and an authentic assessment on football skill learning achievement.

When it comes to transporting energy over long distances it is necessary to consider the effect of the capacitance, since each phase has a different capacitance causing each line to introduce an imbalance to the electrical system, for this reason, it is necessary to study the transposition of the cables. In the present work, several simulations of transmission lines with and without transposition are made, and the voltage unbalance that occurs as the line is longer has been verified. The simulations have been carried out under conditions of balanced load and fixed voltage in the arrival bar. Using the Sim Power Systems tool from Matlab, it was possible to check the behavior of the parameters of the line, depending on the geometric layout of the structure and its length. By applying this software, the objective is achieved by checking the stress unbalance problems suffered by a transmission line when transposition is not made.","PeriodicalId":303507,"journal":{"name":"International journal of physical sciences and engineering","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129531447","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}
