Soil Mechanics (Geotechnics
Triaxial tests but the most common ones are; Consolidated Drained also known a CD, Consolidated Undrained tests which is also referred to as UD and Unconsolidated Undrained. In the consolidated drained or CD, the test is done through consolidating and shearing while compressing it with the drainage. In the second type of test, the sample is not drained and in the third type of test, the sample is constantly compressed.A; can be referred to as the colluviums or top soil, B; is the Residual soil

Detailed Cycle Analysis of Turbofan Engine
For the basic turbojet, the hot exhaust gas passes through fan turbines, the core and then out through the nozzle. The surplus of the inbound air passes through the bypasses and fan. Sometimes it goes about the engine. This is just like the air via a propeller. The velocity of the air that passes via the fan is higher than the free stream. A turbofan gets a portion of its thrust from the fan and the rest from the core (Peter Galison 2000, p.In the analysis of the engine cycle, the bypass ratio

Series resonance
Basically, selectivity defines how well an RLC (resonant) circuit responds to a certain frequency while discriminating against all other frequencies.In a series RLC circuit the capacitive resistance, XC and the inductive resistance, XL have opposite effects on the phase angle thus the total their total impedance is less than the individual resistances. The circuit is inductive when the inductive resistance, XL, is more than the capacitive resistance, XC, while it is capacitive when the

The experiment could also be done in an area with vacuum conditions in order to minimize the interferences in obtaining the readings demonstrated to air resistance. Whenever the capacitor is by-passed by an emitter, and capacitance of the coupled capacitor is large in regards to the AC frequency signal, the capacitors would be approximated as a circuit that is short (BS EN 1097-2, 1998). Whenever the input signal or voltage is increased the output voltage and the signal would be further vary

Cost effective low carbon buildings
This was followed by the advancement in design as people started to integrate long lasting material like Timber, stones and clay. This was to be quickly followed by synthetic materials like bricks which were not only long lasting but also far prestigious and a symbol of success. Later on in the industrial revolution poorer populations were to turn to plastics and metals with industries going for metal when creating industrial structures since it was cheaper to bricks.Krygiel et al (2008) notes
