In this chapter four combinations of input features and the feedforward, cascade forward and recurrent architectures are compared for the task of forecast tourism time series. The input features of the ANNs consist in the combination of the previous 12 months, the index time modeled by two nodes used to the year and month and one input with the daily hours of sunshine (insolation duration). The...

The seasonal distribution in the onset of polymyalgia rheumatica (PMR) was determined in 58 patients with the disease and compared with that in 44 patients affected by rheumatoid arthritis of elderly onset (EORA). Thirty six (62%) cases of PMR developed during May to August; by contrast, only 14 (31%) cases of EORA developed in the same months, this latter disease failing to show any seasonal c...

Libya experiences an influence of political instability which significantly disturbs the lifestyle economics. Consequently, growth power demand and generated is no longer met. They have obviously led to load shedding due generation deficit. In meantime, has annual average amount 3500 hours sunshine solar irradiance rate 7 kWh/m2/day. However, 4,134 million LYD government fund results in Tariff ...

Under natural conditions the vole (Microtus agrestis) breeds in the spring and summer but not in the autumn and winter. This seasonal change was attributed by Baker & Ranson (1933) to the influence of hours of sunshine, and in the laboratory it has been shown that photoperiod affects the growth ofgonads and maintenance of their activity (Baker & Ranson, 1932; Clarke & Kennedy, 1967; Breed & Cla...

Psychological studies support the existence of an influence of weather on mood. Saunders (1993) and Hirshleifer and Shumway (2001) argue that the weather could affect the behaviour of market traders and, therefore, it should be reflected in the stock returns. This paper investigates the possible relation between weather and market index returns in the context of the Spanish market. In 1989, thi...

Based on climate data and social statistics of Guangzhou observatory from 1952 to 2014,this paper used Linear trend analysis, Morlet wavelet transform analysis, Mann-Kendall mutation test etc., to analyze the trend of climate change in Guangzhou nearly 65 years. The results showed that climatic conditions in Guangzhou in recent 65 years showed a warming and drying trend and this trend had becom...

Mixtures of single-base propellant with chlorine and bromine-containing polymers in different ratios, applied in mines and quarries abroad, were investigated. The exoeffects: maximum temperature of the peak, quantity of released heat and loss of mass were determined by a differential scanning calorimetry, after a standard aging of 120 and 240 hours under conditions imitating the sunshine. Combu...

Seasonal Changes in Blood Pressure: Possible Interaction Between Sunlight and Brain Serotonin To the Editor: Whoever wishes to investigate medicine properly, should proceed thus: in the first place to consider the seasons of the year, and what effects each of them produces for they are not at all alike, but differ much from themselves with regard to their changes.
