The focus of this contribution is the estimation of multi-step-ahead linear multivariate predictors of the output making use of finite input-output data sequences. Different strategies will be presented, the common factor being the exploitations of geometric operations on appropriate subspaces spanned by the data. In order to test the capabilities of the proposed methods in predicting new data, a

Aim: To assess the rate of complications following hypospadias repair in a consecutive series of boys and the correlations of those complications with their preoperative symptoms, degree of hy- pospadias and method of operation. This study was conducted to address the question of whether all boys with all degrees of hypospadias should undergo reconstruction. Methods: This was a prospective cohort

The selection of appropriate working media for organic Rankine cycles (ORC) is essential for the optimization of their performance. Dry fluids are widely used in existing ORC because, unlike wet fluids, they do not need to be superheated to avoid wet expansion that may cause damage to the expander. However, regeneration is sometimes needed for fluids with a highly dry behavior in order to improve

Improvement in isentropic total to total efficiency of a low reaction turbine stage by airfoil redesign was considered in first part of the paper. Further, modifications in the flow path of the baseline stage is considered in second part of the paper. Flow path of the baseline stage incorporates axisymmetric meridional endwall contour(commonly called Russian kink). For a stage comprising of high a

The present work approaches the idea of increasing the efficiency of an industrial steam turbine stage. For this endeavor, an industrial steam turbine stage comprising of prismatic stator and rotor is considered. With the velocity triangles as input, airfoil design is carried out. Firstly, the rotor is redesigned to take care of any incidence issues in the baseline case. In rotor blades, the peak

Maritime transportation is a significant contributor to So x, NO xand particle matter emissions, even though it has a quite low CO2 impact. New regulations are being enforced in special areas that limit the amount of emissions from the ships. This fact, together with the high fuel prices, is driving the marine industry towards the improvement of the energy efficiency of current ship engines and th

It is well-known and experimentally conrmed that the mechanical re-sponse to loading of small enough structures diers from what applies to themacro-scale. This is valid for structures of linear measures at the nano-scale,typically below about 50nm. In addition to pure size eects also the crys-tallographic orientation becomes important at this scale.

This chapter brings empirical data to the debate about the ability of law to contribute to the empowerment and development of informal workers, looking into the case of street vendors. Looking into the potential that law has for poverty reduction is an important goal and for that reason, this research aims to understand whether legal change, getting the legal permit to sell, can in fact bring empo

In this paper, we consider precoder designs for multiuser multiple-input-single-output (MISO) broadcasting channels. Instead of using a traditional linear zero-forcing (ZF) precoder, we propose a generalized ZF (GZF) precoder in conjunction with successive dirty-paper coding (DPC) for datatransmissions, namely, the GZF-DP precoder, where the suffix ‘DP’ stands for ‘dirty-paper’. The GZF-DP precode

The Swedish welfare state model has its roots in home turf as well as in the soil of othernations, mainly Germany and Britain. It took on its characteristic shape as the People’s Home in the 1930s, when national models to the left and right of the political spectrum in many countries were built around “the people”. At the time it was also labelled “the middle way” between capitalism and socialism.
