Head injury is common and preventable. Assessment of the head injury patient includes airway, cervical spine protection, breathing, circulation, haemorrhage control and the Glasgow Coma Scale. Hypotension, hypoxia, hypocarbia and hypercarbia should be avoided by continuous monitoring of vital signs and hourly head chart to prevent secondary brain injury. This paper aims to assist primary health...
This paper presents a dynamic linear model for modeling hourly ozone concentrations over the eastern United States. That model, which is developed within an Bayesian hierarchical framework, inherits the important feature of such models that its coefficients, treated as states of the process, can change with time. Thus the model includes a time–varying site invariant mean field as well as time v...
Due to the short duration, high intensity and sudden of torrential rain, mountain torrents are easily formed in northern hilly area.The distributed hydrological model is used as main means rain-flood forecasting. Rainfall an important input,its spatial interpolation accuracy time scale directly affect forecast results.Therefore, this paper, calculation analysis rainstorm process with hourly car...
A new constellation of radio occultation satellites called COSMIC-2 (Constellation Observing System for Meteorology, Ionosphere, and Climate-2) is providing unprecedented dense measurements the tropical atmosphere, with on average more than 4,000 high quality observations per day over 40°N–S. We use these data to evaluate large- small-scale thermal variability in lower stratosphere during Octob...
Accurate and reliable wave forecasting is crucial for optimizing the performance of various marine operations, such as offshore energy production, shipping, fishing. Meanwhile, predicting height achieving sustainability a renewable source, it enables harnessing power efficiently based on water-energy nexus. Advanced models, machine learning models semi-analytical approach, have been developed t...
Rainfall data of high temporal resolution are required in a multitude of hydrological applications. In the present paper, a temporal rainfall disaggregation model is applied to convert daily time series into an hourly resolution. The model is based on the principles of random multiplicative cascade processes. Its parameters are dependent on (1) the volume and (2) the position in the rainfall se...
The Short-term forecasting of electric load plays an important role in designing and operation of power systems. Due to the nature of the short-term electric load time series (nonlinear, non-constant, and non-seasonal), accurate prediction of the load is very challenging. In this article, a method for short-term daily and hourly load forecasting is proposed. In this method, in the first step, t...
Pollen forecasting is of increasing interest as a way to help the general public avoid contact with allergy-inducing pollen. It was recently reported that the dynamics underlying pollen concentration series is very similar to that of low-dimensional deterministic chaos, thus opening up new avenues of development in local pollen forecasting. Our analysis of hourly cedar pollen series for two sea...
