International Art Market - Essay Example National and local governments have also acknowledged the significance of culture and art in the promotion of policies, as reinforcement to the linkages between the two and in spheres of local development (Galloway and Dunlop 17). Culture and art have taken a center stage in the agendas covered by policy-making, and this is evident from the economic regeneration models adopted by Netherlands, Scotland, Singapore, New Zealand and South Korea among other countries (Galloway and Dunlop 18). Irrespective of the growing interest in cities and their histories, the museums of different cities have received less attention as sources of valid information about the places of multiple eras and shapes. City museums have continued to be viewed as extraneous and unresponsive to the changes taking place within the societies around them, therefore not beneficial to the residents of the city (Filene 14). Taking into account the centrality of contemporary city life, city museums among other art centers, should not only act as tourist and historical centers in the city, but should assume a more central role in contemporary city life (Butler-Bowdon and Hunt 76-77). In the case of Rotterdam, the Museum of Rotterdam has played a key role, over a number of years, towards increasing the role and the importance of the present city. In response to post-modern trends, the museum has done more than positioning the modern city as the central point of its work (Marstine 28). The transnational na ture of the city has become the focal point of the policies developed by the museum, and the workers of the museum have taken up the responsibility of mediating between the works of the museum, the ways in which it presents art and the life of the people in the city. Towards realizing the goal of regenerating the city, the museum trains its curators, enabling them to develop the ability to use fashionable heritage as an important ingredient in creating the future of the

Electronics ( 1 of 1) operational Amplifier Design - Coursework Example Non-ideal Op Amps might have inputs, at the two pins, having unequal voltages; there may be current flowing out or into the two input pins. The non-ideal characteristics are responsible for circuit loading, introduced noise, and the reduced Gain and input resistance (Rin). Input offset voltage is a small voltage that is applied at the input terminals in order to make the output voltage zero when two inputs’ terminals are grounded. A number of signal inputs can be integrated into the inverting amplifier via connection of individual sources with separate resistors to an Op Amp’s input; this will result into inverted sum of all the inputs. A summing amplifier’s input combinations produce an output that reflect weighted sum of the total inputs. Figure 1 shows a summing amplifier, a modification of an inverting amplifier; the inverting amplifier has been utilized since it can handle several or many inputs simultaneously. The summing amplifiers are practically used audio mixers and digital temperature recorders. A prelab procedure was carried on a summing amplifier as shown in Figure 1 with the power supplies at  ±10 V, choosing R1 to be 4.7 kâ„ ¦, hence VOUT= - (2 VA + VB ) if R3 = R1 = 10kâ„ ¦. Pspice was utilized in verifying both hand-calculations and the circuit operation. The circuit’s plots were taken, gains compared between hand-calculations and theoretical, and the ratio of VOUT and VIN were observed using the waveform amplitudes. The circuit was maintained as above in the Figure.2, and values from the prelab were used. The dual supply was  ±10 V. A 3 Vpp and 1 kHz sine was channeled at input A while a voltage of 7V from the power supply was channeled at input B. Accurate sketches of the output and input waveforms were taken; using a â€Å"DC† couple oscilloscope. From the formula = = 2VA + VB it is possible to obtain the Digital to Analogue Conversion
