Question:
(a) Spreading the spectrum for signal transmission helps alleviate the narrow band interference problem. What is narrow band interference? State and describe 2 different techniques that can be used to spread the spectrum.
(b) Describe the following terms in the Bluetooth architecture: (i) Piconet (ii) Master (iii) Slave (iv) Parked Devices (v) Standby Devices (vi) Scatternet
(c) IEEE802.11 supports two types of network architectures, describe these architectures with the support of diagrams detailing the network components.
(d) New types of computer based devices arise from:
(i) Specialisation (ii) Convergence (iii) Disaggregation and decentralization
Explain each of the term above and provide an example for each of these cases.
(e) A key component to the success of Ubiquitous computing is sustainability. What is meant by sustainability when associated with Ubiquitous Computing and what are the main sustainability concepts associated with Ubiquitous Computing?
BLADE TWIST: Rotational velocity and its effect on the Angle of Attack depends on the radius of the blade element in question. A blade element near the blade root (hub) will h
Torsional Divergence Lets first try to explain and interpret torsional divergence for the aerofoil structural model physically. An additional figure describing the mechanical s
Turbine engines cooling : Turbine engines are designed to convert heat energy into mechanical energy. The combustion process is continuous and, therefore, heat is produced. On
Exhaust Jet Mixing: Figure shows that the noise from the exhaust jet is the main contributor to the total noise generated by a low by-pass ratio turbo-fan. For a turbo-jet the
h(t) is an analog IIR filter, with the poles lambda_1 = -1, lambda_2 = -1+i, lambda_3 = -1-i and no zeros. let h[n] be a digital IIR filter with poles which defined by e^lambda_i a
