Crime varies greatly by hour of day—more than by any other variable. Yet numbers of cases declines greatly when fragmented into hourly counts. Summary indicators are needed to conserve degrees of freedom, while making hourly information available for description and analysis. This paper describes some new indicators that summarize hour-of-day variations. A basic decision is to pick the first ho...

Solar radiation data are available for many locations on an hourly basis. Simulation studies of solar energy systems have generally used these hourly values to estimate longterm annual performance, although solar radiation can exhibit wide variations during an hour. Variations in solar radiation during an hour, such as on a minute basis, could result in inaccurate performance estimates for some...

Burkholderia pseudomallei, the causative agent of melioidosis, is endemic in southeast Asia and northern Australia. In recent years, the incidence of melioidosis has increased worldwide. Septic arthritis is a rare but well-recognized manifestation of melioidosis. Patients with underlying medical conditions, such as diabetes mellitus, renal impairment, cirrhosis, and malignancy are at greater ri...

Quantitative assessments of home-range dynamics and movements of long-tailed weasels (Mustela frenata) are lacking, in spite of the importance of these data to understanding how habitat fragmentation influences behavior, ecology, and interspecific interactions. During autumn to late winter 1998–2000, we monitored 11 long-tailed weasels (7 male, 4 female) via radiotelemetry to examine home-range...

Accumulated growing degree-days (aGDD) are widely used to predict phenological stages of plants and insects. It has been shown in the past that the best predictive performance is obtained when aGDD are computed from hourly temperature data. As the latter are not always available, models of diurnal temperature changes are often employed to retrieve the required information from data of daily min...

OBJECTIVE To determine the therapeutic efficacy of adjuvant use of voriconazole, 1%, eyedrops in the treatment of refractory fungal keratitis. METHODS A prospective open-label trial was conducted to determine voriconazole levels obtained in human aqueous humor after administration of a 1% solution, preserved with 0.01% benzalkonium chloride, every 6 hours for 3 days, or hourly for 4 doses. Te...

This paper reports on the results of a dynamic pricing experiment that compares the performance of three popular pricing programs–hourly pricing, critical peak pricing, and critical peak-pricing with a rebate–for a representative sample from the population of households in the District of Columbia. The sampled households differ in terms of their income levels, electricityusing appliance holding...

Near-real time estimates of biomass burning emissions are important for air quality monitoring and forecasting. We present here the preliminary analysis of global biomass burning emission product (GBBEP) produced from geostationary-satellite-derived fire radiative power (FRP) in near-real time. Specifically, the FRP is retrieved at an interval of 15 to 30 minutes using WF_ABBA_V65 (Wildfire Aut...

This empirical paper compares the accuracy of six univariate methods for short-term electricity demand forecasting for lead times up to a day ahead. The very short lead times are of particular interest as univariate methods are often replaced by multivariate methods for prediction beyond about six hours ahead. The methods considered include the recently proposed exponential smoothing method for...

Day-ahead half-hourly demand forecasts are required for scheduling and for calculating the daily electricity pool price. One approach predicts turning points on the demand curve and then produces half-hourly forecasts by a heuristic procedure, called profiling, which is based on a past demand curve. This paper investigates possible profiling improvements. Using a cubic smoothing spline in the h...
