Many factors impact a city’s water consumption, including population distribution, average household income, water prices, water conservation programs, and climate. Of these, however, meteorological effects are considered to be the primary determinants of water consumption. In this study, the effects of climate on residential water consumption in Las Vegas, Nevada, were examined during the peri...

In the present work the concepts of dynamic template matching and frame differencing have been used to implement a robust automated single object tracking system. In this implementation a monochrome industrial camera has been used to grab the video frames and track an object. Using frame differencing on frame-by-frame basis a moving object, if any, is detected with high accuracy and efficiency....

Changes in the timberline ecotone vegetation of Nanda Devi National Park (NDNP) was studied over a period of 30 years (1980–2010). Our study based on remote sensing analysis of Landsat MSS and TM images suggests no geographical shift in the upper limit of timberline, while the subalpine forest’s canopy has increased substantially. Decrease in heterogeneous reflectance pattern near upper boundar...

This paper presents a comprehensive review of all the options available for computing derivatives of multidisciplinary systems in a unified mathematical framework. The basic building blocks for computing derivatives are first introduced: finite differencing, the complex-step method and symbolic differentiation. A generalized chain rule is derived from which it is possible to derive both algorit...

Abstract—The objective of this research is to forecast the monthly exchange rate between Thai baht and the US dollar and to compare two forecasting methods. The methods are Box-Jenkins’ method and Holt’s method. Results show that the Box-Jenkins’ method is the most suitable method for the monthly Exchange Rate between Thai Baht and the US Dollar. The suitable forecasting model is ARIMA (1,1,0) ...

A new method of system evaluation that focuses on the impact the system has on a data series that served as the rationale for systems implementation was designed and modeled by the authors. Called outcome-based evaluation, this method is founded on the concept of intervention analysis and employs interrupted time series designs to determine the impact of an information system on specific organi...

The establishment of Christmas tree plantations over the last 50 years in Greece has provided an additional income for the inhabitants of certain mountainous and semi-mountainous regions of the country and contributed to their development. In this paper is used a neural network which combined with ARIMA which makes forecast of number of actually cut Christmas trees until the year 2015.

Time series intervent.ion analysis is used to ascertain the impact that one or more interventions have on a time series. For example, the t.ime series may be monthly revenues from the sale of n product with t,he int.ervention being the implementation of a new marketing strategy. Using the ARIMA procedure in SASjETS@ soft.ware, a large class of time series models are available to pel'form a t.im...
