Higher order wavelet neural networks with Kalman learning for wind speed forecasting

Abstract

Objective: The goal of the present study was to assess the health-related quality of life of a group of family caregivers of individuals with traumatic brain injury from Guadalajara, Mexico. Patients and methods: Ninety family caregivers of individuals with traumatic brain injury and 83 healthy controls completed the Short-Form 36, a self-report health-related quality of life measure composed of 8 component areas: physical functioning, role-physical, bodily pain, general health, vitality, social functioning, mental health, and role-emotional. The samples were statistically similar with respect to age, gender, marital status, and education. However, caregivers had significantly lower household income than controls. Results: After controlling for income, results showed significantly lower scores for traumatic brain injury caregivers compared with healthy controls on 6 Short-Form 36 subscales: role-emotional, vitality, mental health, social functioning, bodily pain, and general health. Conclusion: Caregivers of individuals with traumatic brain injury living in Guadalajara, Mexico report having poorer health-related quality of life across various domains including mental and general health. Future studies should be conducted to determine which specific factors (e.g. lack of services, physical strain of providing care) are responsible for reduced health-related quality of life in these areas. It is likely that resources, such as respite services, adult day-care, aides, outpatient rehabilitation, psycho-educational programs, and support groups would increase health-related quality of life for these individuals.

Smith, E.N.",,"2010",,"A study was conducted to examine the adult male specimens of Crotalus ericsmithi, C. lannomi and C. stejnegeri deposited at the Amphibian and Reptile Diversity Research Center, University of Texas at Arlington. Around 15 specimens of long-tailed rattlesnakes had been deposited in museum collections. A long tail might be a primitive character state in rattlesnakes thereby casting doubt on the monophyly of long-tailed rattlesnakes. Hemipenial characters are particularly useful in evolutionary studies because they are closely associated with species differentiation and reproductive behaviors. Although C. stejnegeri was described nearly nine decades ago, some features of its unique hemipenis have not been published. The hemipenes of Crotalus stejnegeri, C. ericsmithi, and C. lannomi are remarkably similar to each other and dissimilar to those of other rattlesnakes. Nonetheless there are distinctions among the three species. All three hemipenes have lobes of similar length, about 17 mm long, allowing for accurate comparison.",,,,,,,,,"http://hdl.handle.net/20.500.12104/41866","http://www.scopus.com/inward/record.url?eid=2-s2.0-77955604884&partnerID=40&md5=91dcca9a902361d3c8d3fe62a71c61c9",,,,,,"1",,"Phyllomedusa",,"69

Sanchez, E.N.",,"2011",,"In this paper, a Higher Order Wavelet Neural Network (HOWNN) trained with an Extended Kalman Filter (EKF) is implemented to solve the wind forecasting problem. The Neural Network based scheme is composed of high order terms in the input layer, two hidden layers, one incorporating radial wavelets as activation functions and the other using classical logistic sigmoid, and an output layer with a linear activation function. A Kalman filter based algorithm is employed to update the synaptic weights of the wavelet network. The size of the regression vector is determined by means of the Lipschitz quotients method. The proposed structure captures more efficiently the complex nature of the wind speed time series. The proposed model is trained and tested using real wind speed data values. " 2011 IEEE.
