Rational-spline approximation with automatic tension adjustment
, 1984 An algorithm for weighted least-squares approximation with rational splines is presented. A rational spline is a cubic function containing a distinct tension parameter for each interval defined by two consecutive knots.

Biotechnology and Bioengineering, EarlyView.ABSTRACT The agitation power input substantially impacts the oxygen transfer rate in aerobic fermentation processes. Furthermore, in a carbon‐limited process where the substrate feed rate is controlled by the concentration of dissolved oxygen, the power input will consequently govern the feed rate.

Real‐Time Biomass Estimation in High‐Density Yeast Fermentations Using Soft Sensor Modeling
Biotechnology and Bioengineering, EarlyView.Accurate biomass measurements, both offline and online, are essential to improve prediction and control in yeast fermentation. This study develops regression‐based predictive models to correlate offline measurements (Dry Cell Weight and OD600 from a spectrophotometer) with online OD860 probe signals to provide accurate real‐time biomass estimations and

Cone spline approximation via fat conic spline fitting
, 2006 Fat conic section and fat conic spline are defined. With well established properties of fat conic splines, the problem of approximating a ruled surface by a tangent smooth cone spline can then be changed as the problem of fitting a plane fat curve by a ...

An arc spline approximation to a clothoid
, 2004 The clothoid is a spiral used in highway and railway route design. Clothoids are transcendental functions and so have been approximated by polynomials, by power series and continued fractions, and by rational functions.

Biotechnology and Bioengineering, EarlyView.ABSTRACT Improving cell‐specific productivity remains a central objective in biopharmaceutical manufacturing. In this study, the effect of blue light illumination on IgG1‐producing CHO DP‐12 cells was systematically evaluated across batch, fed‐batch, and perfusion cultivations in controlled 3 L bioreactor systems.

A duality approach to spline approximation
, 2006 This dissertation discusses a new approach to spline approximation. A periodic spline approximation M,m,N(x) = Σk=1NαkΦM,k(x) to a periodic function (x) is determined by requiring m,j, - M,m,N > = 0 for j = 1,...,N, where the ΦL,k's are the unique ...

Business Strategy and the Environment, EarlyView.ABSTRACT This study examines how stakeholder engagement, conceptualized as a boundary‐spanning organizational capability, interacts with firms' decarbonization strategies, in relation to climate action commitments (CACs) in voluntary initiatives.

Clinical Anatomy, EarlyView.ABSTRACT Understanding how pancreas size and shape change with normal aging is critical for establishing a baseline to detect deviations in type 2 diabetes and other pancreatic disease. We measure pancreas size and shape using morphological measurements from early development through aging (ages 0–90).

Bayesian inverse ensemble forecasting for COVID‐19
Canadian Journal of Statistics, EarlyView.Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...
