On the relationship between the Method of Least Squares and Gram-Schmidt orthogonalization

The method of Least Squares is due to Carl Friedrich Gauss. The Gram-Schmidt orthogonalization method is of much younger date. A method for solving Least Squares Problems is developed which automatically results in the appearance of the Gram-Schmidt orthogonalizers. Given these orthogonalizers an induction-proof is available for solving Least Squares Problems.

La ventilazione non-invasiva a pressione positiva nell’insufficienza respiratoria acuta ipercapnica: 10 anni di esperienza clinica di una Unità di Terapia Semi-Intensiva Respiratoria

PremessaSebbene numerosi studi prospettici, controllati e randomizzati abbiano dimostrato il successo della ventilazione non-invasiva a pressione positiva (NIV) in casi selezionati di insufficienza respiratoria acuta ipercapnica (IRA) in setting con intensità di cura differenti, i dati di pratica clinica relativi all’uso della NIV nel “mondo reale” sono limitati. Scopo Riportare i risultati della nostra esperienza clinica sulla NIV nell’IRA applicata nell’Unità di Terapia Semi-Intensiva Respiratoria (UTSIR) allocata all’interno dell’Unità Operativa di Pneumologia di Arezzo negli anni 1996-2006 in termini di: tollerabilità, effetti sui gas ematici, tasso di successo e fattori predittivi del fallimento.MetodiTrecentocinquanta dei 1484 pazienti (23.6%) consecutivamente ammessi per IRA nella nostra Unità Operativa di Pneumologia durante il periodo di studio hanno ricevuto la NIV in aggiunta alla terapia standard, in seguito al raggiungimento di criteri predefiniti impiegati di routine.RisultatiOtto pazienti (2.3%) non hanno tollerato la NIV per discomfort alla maschera, mentre i rimanenti 342 (M: 240, F: 102; età: mediana (interquartili) 74.0 (68.0-79.3) anni; BPCO: 69.3%) sono stati ventilati per >1 ora. I gas ematici sono significativamente migliorati dopo 2 ore di NIV (media (deviazione standard) pH: 7.33 (0.07) versus 7.28 (7.25-7.31), p<0.0001; PaCO2: 71.4 (15.3) mmHg versus 80.8 (16.6) mmHg, p<0.0001; PaO2/FiO2: 205 (61) versus 183 (150-222), p<0.0001). La NIV ha evitato l’intubazione in 285/342 pazienti (83.3%) con una mortalità ospedaliera del 14.0%. Il fallimento della NIV è risultato essere predetto in modo indipendente dall’Apache III (Acute Physiology and Chronic Health Evaluation III) score, dall’indice di massa corporea e dal fallimento tardivo della NIV (> 48 ore di ventilazione) dopo iniziale risposta positiva.ConclusioniSecondo la nostra esperienza clinica di dieci anni realizzata in una UTSIR, la NIV si conferma essere ben tollerata, efficace nel migliorare i gas ematici e utile nell’evitare l’intubazione in molti episodi di IRA non-responsivi alla terapia standard.

A neurofuzzy network knowledge extraction and extended gram-Schmidt algorithm for model subspace decomposition

This paper introduces a new neurofuzzy model construction and parameter estimation algorithm from observed finite data sets, based on a Takagi and Sugeno (T-S) inference mechanism and a new extended Gram-Schmidt orthogonal decomposition algorithm, for the modeling of a priori unknown dynamical systems in the form of a set of fuzzy rules. The first contribution of the paper is the introduction of a one to one mapping between a fuzzy rule-base and a model matrix feature subspace using the T-S inference mechanism. This link enables the numerical properties associated with a rule-based matrix subspace, the relationships amongst these matrix subspaces, and the correlation between the output vector and a rule-base matrix subspace, to be investigated and extracted as rule-based knowledge to enhance model transparency. The matrix subspace spanned by a fuzzy rule is initially derived as the input regression matrix multiplied by a weighting matrix that consists of the corresponding fuzzy membership functions over the training data set. Model transparency is explored by the derivation of an equivalence between an A-optimality experimental design criterion of the weighting matrix and the average model output sensitivity to the fuzzy rule, so that rule-bases can be effectively measured by their identifiability via the A-optimality experimental design criterion. The A-optimality experimental design criterion of the weighting matrices of fuzzy rules is used to construct an initial model rule-base. An extended Gram-Schmidt algorithm is then developed to estimate the parameter vector for each rule. This new algorithm decomposes the model rule-bases via an orthogonal subspace decomposition approach, so as to enhance model transparency with the capability of interpreting the derived rule-base energy level. This new approach is computationally simpler than the conventional Gram-Schmidt algorithm for resolving high dimensional regression problems, whereby it is computationally desirable to decompose complex models into a few submodels rather than a single model with large number of input variables and the associated curse of dimensionality problem. Numerical examples are included to demonstrate the effectiveness of the proposed new algorithm.

Investimento reprodutivo em fêmeas de populações sintópicas de Dendropsophus nanus (Boulenger, 1889) e D. sanborni (Schmidt, 1944) (Anura: Hylidae)

As espécies estudadas neste projeto, Dendropsophus nanus e Dendropsophus sanborni, são pererecas de pequeno porte, morfologicamente semelhantes e ocupam nichos similares. O presente trabalho foi realizado na Floresta Estadual Edmundo Navarro de Andrade, município de Rio Claro, estado de São Paulo e teve como objetivo obter informações acerca da biologia reprodutiva de ambas as espécies. Os principais resultados obtidos foram referentes à: (1) Relações de tamanho-fecundidade em fêmeas de D. nanus, sendo que foi significativa a correlação entre número de ovos e comprimento rostro-cloacal de fêmeas, o que não ocorreu para correlações entre tamanho dos ovos e CRC de fêmeas e entre tamanho e número de ovos, (2) Seleção do tamanho dos machos em D. nanus, com as fêmeas aparentemente acasalando com machos proporcionalmente mais leves e (3) Comportamento de desova de D. sanborni semelhante ao relatado para D. werneri, havendo dois tipos de interação parecidos: um envolvendo movimentos da cabeça e o outro das patas traseiras do macho, ambos descritos pela primeira vez para D. sanborni neste estudo.
