This article presents a new generalized direct synthesis method to design multiband bandpass filters (MBPFs). Based on the proposed frequency transformation technique, it can be used synthesize an arbitrary number of starting from low-pass prototype filter. allows determining analytically all resonant angular frequencies and slope parameters low high cut-off as initial specifications whatever b...

The target costing technique, mathematically discussed by Sauers, only uses the p C index along with Taguchi loss function and X -R control charts to setup goal control limits. The new specification limits derived from Taguchi loss function is linked through the p C value to X -R control charts to obtain goal control limits. In this study, the target costing technique is exploited by further co...

One research field in Leipzig deals with the design of high strength lightweight-aggregate concretes (HSLWAC). Due to the huge waveband of this concretes with all possible combinations of lightweight-aggregates and mortar matrix the formulation of general rules is difficult. Therefore both components lightweight-aggregates and mortar matrix will be investigated in detail in order to achieve a d...

Recommender Systems have been successfully deployed in a variety of e-Commerce application scenarios. Customer selections of services or standard goods are supported as well as product configuration tasks. Little research has however been done on the application of Recommender Systems outside the virtual domain in real-world stationary trade. This surprises as on a business side, brick-and-mort...

This paper proposes a voice decomposition method based on voice model. Using correlation distance as a criterion frequency domain decomposition is formulated. For a pair of correlation coe cient vectors minimizing powers of spectra is characterized using quadratic programming problem with constraint, where values of powers are non-negative. The solution of the problem without constraint is calc...
