“…The two direct relationships which are students' characteristics (β=0.497, t-values=8.342, p<0.05) and technology (β=0.356, t-values=4.323, p<0.05) included in Figure 1 are statistically significant and accepted for instructors' characteristics (β=0.082, t-values=1.512, p>0.05) As such, Hypothesis 2 and 3 were supported in this study. The significance estimated are obtained using a percentile bootstrap [26]. Results show that the lower limit and upper limit values do not contain zero, and explained how the direct effects are significantly different from zero with 95 percent co nfidence [23].…”

The incorporation of E-learning in both private and public tertiary education can help expedite the learning process. The utilization of fast-paced technology with E-learning also allows for a more flexible and convenient learning process. E-learning platforms can be accessed anywhere as long as there is an internet connection, including at home, the workplace, restaurants or while travelling. This allows for the benefit of distance learning. As such, the current study aims to examine the factor effectiveness of E-learning based on three variables, namely technology, instructors’ characteristics and students’ characteristics and their impact on distance learning. The education system has greatly evolved from the use of apparatus such as chalk and blackboards to the modern use of projectors to conduct lessons. In the current age, E-learning will have an effect on both instructors and teaching technology, aside from the students themselves. As an example, students are expected to know how to utilize these systems in their lessons, instructors must receive training in E-learning systems management and in terms of technology, the E-learning systems must be updated and operated using the most recent upgrades. E-learning is also cost-efficient, less time consuming and reduces the burden on both students and educators.

“…A suitable sensor must be used for this prepossess like high frequency current transformer (HFCT), that can confine hefty frequency gestures along the path of pulses by balding them round the cable earth band or the core of the cable, this way represents a common technique of PD recognition in the cable. The HFCT sensor has frequency band from hundreds of KHZ to thousands of MHZ, it can be put easily, safe and reliable test method [21,22].…”

<p>A partial discharge described as anon-linear electrical break-down even that happened in a section of insulating area between two conduct which are at different potentials the damage of the insulating material, these conductors have a different insulating material potential of damage, under AC voltage discharge interval process. In this paper, we propose a Matlab /Simulation software. A detailed analysis of the partial discharge (PD) signal in the underground electric power conductor performed for monitoring, and investigation of numerous effects associated with the partial discharge event, such as heat ,phonic and electrical. Thus, to gain the important data of the insulating material status.</p>

“…The positive power that is absorbed by the load can be determined by the difference between the phases of voltage and current coming from the grid to the load. If there is no phase difference between the voltage and current, then the power is positive [15][16][17][18][19][20].…”

<p>The significance of power or energy measurement has been very acute in recent times with the increase of Grid-Tied Solar PV system that needs Net-Metering. Power can be flown in both directions, from grid to load or from load (PV- Panel) to grid line. If power flow from both side is not calculated and surplus power which is not being used at the time instant is not stored, accurate billing is not possible. That is why a bidirectional power meter is required which can measure both the positive and negative power at any instant. The aim of this paper is to develop a bidirectional power meter using microcontroller. The work of this paper constitutes a microcontroller, a current sensor, bulbs as load and a display. The rms values of voltage and current is determined and showed in the display. Then the calibration is done inside the developed program. After that the power is calculated and showed in the display. Then the direction of the power is determined depending on the direction (whether positive or negative) of the power which is also dependent on the phase difference between the voltage and current. If there is no phase difference between the voltage and current, then the power is positive and leaving from the grid. If there is 180 degree phase difference between the voltage and current, then the power is negative and entering to the grid. The direction of the power flow is very important for efficiently of the proposed meter. For some defined load the accuracy of the developed meter is calculated as 94%.</p>
