Cost-conscious manufacturing – Models and methods for analyzing present and future performance from a cost perspective

Manufacturing is an industry in which the effects of globalization are obvious. Manufacturing costs are a key factor in this respect and affect, for example, decisions about offshoring, i.e., moving production abroad. If Sweden and other Western countries are to maintain large manufacturing sectors, they must be competitive, making cost one of the most critical parameters. The work presented here

Use and evaluation of simulation for software process education: a case study

Software Engineering is an applied discipline and concepts are difficult to grasp only at a theoretical level alone. In the context of a project management course, we introduced and evaluated the use of software process simulation (SPS) based games for improving students’ understanding of software development processes. The effects of the intervention were measured by evaluating the students’ argu

A Positive Feedback Passive Mixer-First Receiver Front-End

This paper presents a technique to reduce the noise figure of a passive mixer-first receiver front-end. By using lower than 50Ω switch resistance in the current-mode passive mixer and introducing a positive feedback from baseband to the RF-input, it can be well matched close to fLO while achieving a noise figure below 3dB, which is otherwise a fundamental limit. A quadrature front-end prototype fo
