This paper presents a low-complexity energy efficient channel pre-processing update scheme, targeting the emerging 3GPP long term evolution advanced (LTE-A) downlink. Upon channel matrix renewals, the number of explicit QR decompositions (QRD) and channel matrix inversions are reduced since only the upper triangular matrices R and R^-1 are updated, based on an on-line update decision mechanism. Th

Abstract What happens if you put assistive robots in the hands of old adults? Will they accept or reject the robot? If they accept the robot, in which ways will the robot change the everyday lives of old adults? Old adults have a lifetime of experience technological changes. Seniors have adopted as well as rejected new technological advances in the past. If domestic assistive robots are adopted an

With increased market competition and advances in modern manufacturing technologies, requirements on customer orders and manufacturing conditions have become more diversified. This paper addresses a dynamic production planning problem for a steel plate fabrication plant with practical flexibility of both customers and manufacturing, such as steel slab-plate matching rules, plate substitution optio

This paper deals with the design of a nonlinear observer for the inverted pendulum. The observer uses the standard structure of the linear observer with the linear model replaced by a nonlinear model. Nominal observer gains are determined from a linearised model. This model is also used to find a compromise between robustness and performance. The stability of the observer is then discussed and con

A simple, fast and efficient method for designing wideband radar absorbers is proposed. The idea is to modify the circuit analog absorber method without perturbing the bandwidth. This is done by utilizing the asymptotic behavior of such an absorber at low frequency and replacing the band-stop resonating frequency selective surfaces with low-pass capacitive ones, which can be synthesized by square

Behovet av geriatrisk och gerontologisk kompetens är stor och det är angeläget att öka antalet specialistutbildade sjuksköterskor inom vård av äldre. Sveriges befolkning blir allt äldre, vilket bland annat beror på att vi blir bättre på att främja människors hälsa och bota sjukdomar. Den ökade medellivslängden till trots, kantas ofta den sista tiden i livet av en period med ett ökat behov av vårdi

Successful projects require two key elements to be set: the time frame for the project and the scope of the project. Accurately deciding these two attributes greatly increases the probability of success. If, for example we would like to build a house, we should start building it in spring so that we can lie the foundations of the house on a non-frozen ground. Moreover, we know that we should be re

A method of producing short chain alcohols from glycerol generated as a byproduct of biodiesel production is provided.

Background How many time's a word appear in a corpu's constitute's it's word frequency. Word frequency affect's memory in robust but puzzling way's. In free recall paradigm's high frequency (HF) word's are easier to recall than low frequency (LF) word's, in list's with homogenou's word frequencie's. If HF and LF word's are mixed together in a list thi's affect recall of HF word's negatively

Using the case study research method as well as empirical quantitative-based simulation methods are becoming increasingly common in supply chain management research. However, rare signs of efforts of combining these are to be found in literature. This paper contributes to the further development of research practices by presenting and discussing the concept of combining case study and simulation.
