The Smart Grid can work in a two — way system using advanced technology. The Smart Grid includes a monitoring system that can record all the electricity flows in the power grid, as well as the ability to control the switching, relays, and circuit breakers of the power grid with the use of automation and communication system. This improvement will have an increase economic growth of the NCR. The Design Project deals with remodelling of the NCR power grid, designing a transmission line communication system and designing a Smart Monitoring system. Design Constraints was considered and trade — off analysis was done to choose the optimal design. The Smart Grid model was simulated using EDSA PALADIN Design Base 5 and the monitoring system was programmed using MATLAB GUI Function.

Thus, all health professionals need to be trained in EBP. An EBP training program was conducted to health professionals in a developing country, the Philippines. The health professionals (medical doctors and allied health professionals [physical therapists and occupational therapists]) were working in hospitals in Manila, Philippines. The program aimed to build capacity in EBP in terms of knowledge and skills. The EBP training program was conducted as a 1-day face-to-face training. Pre- and post-test measures of EBP knowledge and skills were taken prior to and immediately after the 1-day training, using the Fresno test of evidence-based medicine for the medical doctors and the Adapted Fresno test for the allied health professionals. The EBP training program resulted in significant improvements in knowledge and skills for both the medical doctors (change in pre- and post-...

One could use the gradient expansion (GE) to calculate the non-interacting kinetic energy (KE) by the knowledge of the density alone. The system of interest was the cosine potential, which has a periodic potential that can approximately model solids. The density of cosine potential was are obtained by summing singleparticle eigenfunctions that satisfying boundary conditions. The density depends on the potential V0, the length of the unit cell d, the number of electrons per unit η, and the number of unit cells Nc, which was manipulated to explore the behavior of the GE. An extrapolation technique was introduced to calculate the KE within the thermodynamic limit where Nc → ∞. An error analysis for the performance of the GE was implement by plotting the logarithm of percent errors against the order of the GE. The addition of the GE terms systematically improve KE calculations, and the sixth order GE performs the best...

This paper presents the simulation of half adder, half subtractor, full adder, and the full subtractor. The presented circuit contains NAND gates combining the NMOS and PMOS. These CMOS circuitries has the advantage of lower voltage, lower power consumption, and higher energy efficiency. The NMOS and PMOS were bridge together to produce the desired output. This design provides the CMOS half adder, half subtractor, full adder, and full subtractor using the Tanner EDA software tool. The complete CMOS circuit schematic are described in this paper. The design methods and principles are described thereafter. Simulations have been done with the use of the Tanner EDA tool in a CMOS technology standard and response output was verified comparing the obtained waveform along with its truth table. In comparison with conventional logic truth table, T-Spice output simulation matches with theoretical expectations.

Natural causes are inevitable but having a warning device to alert people and prepare them from what's about to come is essential today. In this paper, the Arduino-based disaster management system is proposed. The device created is a disaster management device that consists of temperature, soil drift, accelerometer, tilt, and rain sensor. A hardware prototype model was developed. It is operated through microcontroller Arduino and implemented using the C language. The effectiveness of the proposed method is verified by experimental studies. If a sensor is activated, it will send data to the selected receiver, which is a mobile phone. Acquired data were provided in this article. Results reveal the effectiveness and efficacy of the proposed system. An expressive future directive has been incorporated at the end of this paper.
