Transcranial direct current stimulation

known for being "painless, safe, inexpensive, and portable" (Ramezani et al.) with mild side-effects like tingling, rash, irritability, or itching being the most common reactions making this system ideal to continue to study for use on children. TDCS is known for its effectiveness with children who exhibit spastic diparesis CP. Coupling TDCS with treadmill training, virtual reality, and constraint induced movement therapy (CIMT) that improved gait, mobility, and hemiparesis respectively in children with CP. Although this approach is becoming more prominent, more research studies need to be done before it can be used as an approved treatment for children with CP or other neurological disparities. TMS, is similar to TDCS, but instead of a direct pulse it uses a figure-eight electrical coil on the head to make an electromagnetic field that can control cortical excitability and make permanent changes to the brain function (Ramezani et al.). TMS is used in treating ADHD, ASD, schizophrenia, neurological pain, depression, and much more, but also shows promise when used in children with spastic quadriplegic CP. In those children with CP the electromagnetic induction reduced spasticity by calming the spinal nerves, corticospinal tract, and motor cortex to make mobility…

SIMULATION RESULTS AND DISCUSSION 4.5.1 Compensation of Voltage Sags All the proposed controllers performed to the IEEE standard. Table 4.5 shows voltage sag compensation of the proposed intelligent controllers. Compensated SS value shows the voltage sag compensation capability of the each proposed controller under different fault types and load conditions. In case 1, performance of DVR with proposed fuzzy logic controller has the sag score 0.5056pu observed at sensitive load before…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…

Fig. 3. Schematic Diagram of Power Line Guardians (“PLG”) PLGs are also used to give the real-time data on the lines such as: line current, conductor temperature, frequency, sag [17]-[21]. Fig. 4. The PLG communications system. The diagram (Fig.4) shows the PLG communications system. PLGs (blue) control the power flows on the lines. Super PLGs (red) can control both the power flows and the PLGs. These Super PLGs are also used to communicate with Energy Management Systems (EMS) and allow…

Factors That Contribute to the Digital Divide Transportation One of the crucial factors that contribute to the difficulty to spread technology and business to much of India is the lack of easy transportation. Of the over 1.34 billion people who populate India, 72.2 percent live in 638,000 villages while the remaining 27.8 percent live in only 5,480 towns and urban agglomerations (Population of India 2016, 2016). While urban cities have some paved roads and public transportation means such as…

and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D becomes forward-biased and forms a conduction path for the filter inductor current. The voltage across the filter inductor is the reverse of the output voltage. By using filter inductor volt-second balance…

Secondary coil Toroid Figure 1: Tesla coil (diagram) A primary transformer is a step-up transformer that takes the line voltage of the AC source and steps it up to a range between 12 kV and 50 kV at 60 Hz (Johnson 4). The efficiency of this transformer is largely dependable on the construction of its core. The iron from which the core is made has to be of a high permeability (amount of magnetization within the iron when immersed into a magnetic field) and a low retentivity (portion of…
