The development of advanced microscopes has enabled scientists to further their investigation on the criteria for life. As a result, biologists have been confronted with a baffling question: is there a size limit on life? If so, then just how small can something be before it can no longer be considered alive? Ever since the discovery of nano-sized particles called “nanobacteria” or “nanobes”, researchers have been scrambling to unravel and analyze the mysterious functions of these purported…
Aristotle’s virtue ethics, telos is the first and fundamental element to achieve happiness in human’s nature. In my own field, for example, if I get a chance to be a power electrical engineer fortunately, designing and creating more efficient and safer transmission and distribution circuits will be purpose and goal for me. Because if the goal is realized, it will contribute to developing our human society. In addition to a good telos, I also need to learn and train myself to be professional. For…
Transmission electron microscopy, or TEM, is a variation of low field, high-powered electron microscopy. Created by Ernest Ruska and Max Knoll of the Berlin Technische Hochschule in 1931, the invention of this novel microscope allowed for the surpassing of the visible light resolution barrier. Since its inception, the TEM has become a resolution standard in the field of imagery, and further advances have led to the progression of high quality atomic viewing. The development of the electron…
By Brigid Garrett , Wyatt Mullings, Jesus Sanchez, and Lydia Blaisdell Cable Sensation Russky Bridge, Vladivostok, Russia. What are Cable/Stayed Bridges? A cable/stayed bridge is a bridge that has two towers with cables supporting the bridge itself, as shown above. The towers are called pylon, the crossing area itself is called the roadway. The cables are obviously called cables. The supports underneath on the sides are called abutments, The foundations are located under the ground on the…
4.1.4 Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…
Disturbance or destruction of marine life (including changes in the distribution and types of marine life near the shore) • Degradation of scenic ocean front views from wave energy devices located near or on the shore, and from onshore overhead electric transmission lines 4) Why Oscillating Water Column? There are a number of factors concerned with the installation of the type of ocean wave energy converter. However, the OWC is chosen as one of the optimum measures to tackle the issue of wave…
Do you like the vibe of grass under your feet, or the sand in the middle of your toes, well appreciate all the more unshod contact with the Earth, since that is the thing that Earthing or Grounding truly is! As a child we cherished strolling unshod all over the place... yes it was on account of it felt great on our feet, additionally in light of the fact that our bodies felt the advantages as well. In the event that we could backtrack to those days we would be in an ideal situation, the Earth…
REPORT TCP: Transmission Control Protocol SUMMARY: The idea of TCP congestion control is for each sender to determine the available capacity in the network so that it knows how many packets can be safely transmitted. The congestion window is a state variable for each connection which is used by the sender to limit how much data a sender can transmit into the network before receiving an acknowledgement. This report consist of the simulation of different model of TCP transmission…
UML 91.561 Computer & Network Security I HomeWork 1 Name – Nrupen Abnave Student ID -01382247 1.1 (a) Describe the major structure of a TCP packet and explain the main functions of the TCP headers. - TCP is a transport layer protocol and is connection oriented. Its reliable connection, has error checking and flow control. TCP Headers: 32bits Source and Destination Ports – Each 16bit number. Indicate which application is using the communicating stream. Used by most common…
Harmonics: Harmonic distortions are injected at the generation as well as the consumer end. At the consumer end, harmonics are caused by nonlinear loads such as PCs, CFLs, electronic devices, etc. The harmonics distortion caused by non-linear load such as electric arc furnaces, large concentrations of arc discharge lamps, variable speed motors, saturation of magnetization of transformer and a distorted line current. The current generated by such loads will interact with power system impedance…
