Teaching Manufacturing Strategies and Structures in higher Education

The importance of software systems for the planning and execution of production has drastically increased over the past decades. This has lead to a growth in number of software systems used within sites. The company’s problem today is no longer only to find relevant software systems but rather to coordinate and synchronize existing systems. Students at higher technical educations e.g., bachelors a

Determination of over current protection thresholds for class D audio amplifiers

Monolithic class-D audio amplifiers typically feature built-in over current protection circuitry that shuts down the amplifier in case of a short circuit on the output speaker terminals. To minimize cost, the threshold at which the device shuts down must be set just above the maximum current that can flow in the loudspeaker during normal operation. The current required is determined by the complex

Influence of user hand on the performance of a multiband diversity antenna

The increasing demand on improved reception and high data throughput brings into focus the design of compact multiband antenna terminals with diversity reception capability. In particular, the influence of user on diversity performance is of current interest. In this paper, the diversity performance of compact tri-band antennas (WCDMA850, WCDMA1800 and UMTS 2100) for mobile handsets is evaluated i

European Identity from Below : The Presence of Eurosymbols in Two European Capitals

Abstract in UndeterminedIdentity construction processes have been studied at the national level both from top-down (elite driven process) and from bottom-up (popular movements). In the context of European identity research, Billig's argument for "banal nationalism" has been transposed to the scale of the region by Cram under the name "banal europeanism". The present paper wants to test the process

A 0.8V, 7uA, rail-to-rail input/output, constant Gm operational amplifier in standard digital 0.18um CMOS

A two-stage amplifier, operational at 0.8V and drawing 7/spl mu/A, has been integrated in a standard digital 0.18/spl mu/m CMOS process. Rail-to-rail operations at the input are enabled by complementary transistor pairs with g/sub m/ control. The efficient rail-to-rail output stage is biased in class AB. The measured DC gain of the amplifier is 75dB, and the unity-gain frequency is 870kHz with a 1
