This paper presents theory and algorithms for covariance analysis and stochastic realization without any minimality condition imposed. Also without any minimality conditions, we show that several properties of covariance factorization and positive realness hold. The results are significant for validation in system identification of state-space models from finite input-output sequences. Using the R
Two methods for estimating the sensor offset of a cylinder pressure transducer are developed. Both methods fit the pressure data during pre-combustion compression to a polytropic curve. The first method assumes a known polytropic exponent, and the other estimates the polytropic exponent. The first method results in a linear least-squares problem, and the second method results in a nonlinear least-
Spinal cord injury (SCI) challenges many aspects of life. Common secondary health conditions are sensorimotor impairments, autonomic dysfunction affecting bowel, bladder, sexual and cardiovascular function, pressure ulcers, pulmonary dysfunction, pain and psychological distress. Primary rehabilitation and lifelong follow-up from a specialized interdisciplinary rehabilitation team is needed to atta
The open border between non-living and living matter, suggested by increasingly emerging fields of nanoscience interfaced to biological systems, requires a detailed knowledge of nanomaterials properties. An account of the wide spectrum of phenomena, belonging to physical chemistry of interfaces, materials science, solid state physics at the nanoscale and bioelectrochemistry, thus is acquainted for
Bi-based high temperature superconduting multilayers have been obtained by Molecular Beam Epitaxy (MBE) using a deposition method which consists of both co-deposition and growth interruption techniques. We have studied two kinds of structures in which a layer of BizSrzCuOg+s (2201) is alternately stacked by an insulating layer of CaCuOi or SrCuOi in order to obtain 2201/CaCuO2 or IWl/SrCuO?. multi
During a vote-decision process, citizens elect between some of the parties – not all of them. In this paper, we explore a potential strategic reason to include an additional alternative in the consideration set. Drawing on research from the field of strategic voting, we study incentives to defect to a party at risk of falling below an electoral threshold in order to elect a winning coalition (”ins
Explosive volcanic eruptions can reach the stratosphere and cause elevated concentrations of sulphate particles for months to years. When these particles descend into the troposphere, they can impact cirrus clouds though to what degree is unknown. In this study, we combine three satellite data sets to investigate the impact of downwelling sulphate aerosol on midlatitude cirrus clouds during spring
In this chapter, we explore the relationship between business ethics and faith. We suggest that faith in business ethics predominantly plays the role of the therapeu-tic: It soothes the real functioning of business with various idealized conceptions of it. Unfolding this argument, we begin the chapter by showing how business ethics is largely motivated by a now-shattered faith in the capitalist en
Building a blastema from the stump is a key step of salamander limb regeneration. Stump-derived cells temporarily suspend their identity as they contribute to the blastema by a process generally referred to as dedifferentiation. Here, we provide evidence for a mechanism that involves an active inhibition of protein synthesis during blastema formation and growth. Relieving this inhibition results i
The aim of this work is to aid the development of online handwriting recognition software by using a linguistic approach to the problem of categorizing handwriting styles. This is done by exploring the wide variety of styles among users of the Latin alphabet, trying to explain the variety and finding ways of categorizing the styles. The variety is due to the many variables open to the writer and t
Sustainable and resilient infrastructure projects are necessary for Africa if the continent is to be successful in achieving the Sustainable Development Goals (SDGs) and agenda 2063 of the African Union (AU). The paradigm shift towards a low-carbon society cannot be achieved without sustainable and efficient infrastructure that can withstand the effects of climate change. This chapter discusses th
