[1] Across vast, agriculturally intensive regions of the United States, the spread in predictions of summer temperature and soil moisture under global warming is curiously elevated in current climate models. Some models show modest warming of 2–3C and little drying or slight moistening by the 22nd century, while at the other extreme are simulations with warming as large as 7–8C and 20– 40% redu...

In ducts with varying cross-sectional area and sustaining a subsonic non-isentropic mean flow, the axially flow conditions affect acoustic energy balance of system. This is significant in understanding controlling thermo-acoustic phenomena, particularly combustors. work aims at quantifying change such configurations, using absorption coefficient, $\Delta$. The response duct to forcing determine...

In 1986 S. Sattolo introduced a simple algorithm for uniform random generation of cyclic permutations on a fixed number of symbols. Recently, H. Prodinger analysed two important random variables associated with the algorithm, and found their mean and variance. H. Mahmoud extended Prodinger’s analysis by finding limit laws for the same two random variables.The present article, starting from the ...

This paper discusses the conceptual design of Digital Learning Ecosystems, which, as we argue, are becoming the foundation of nextgeneration Technology-Enhanced Learning systems (TEL systems). We illustrate our argument by a case study on design and development of a Dippler ecosystem. First, the framework for identifying the generations of TEL systems is described and expectations towards next ...

We design a custom spectrum sensing network, called RadioHound, capable of tuning from 25 MHz to 6 GHz, which covers nearly all widely-deployed wireless activity. We describe the system hardware and network infrastructure in detail with a view towards driving the cost, size, and power usage of the sensors as low as possible. The system estimates the spatial variation of radio-frequency power fr...

A novel object tracking algorithm is presented in this paper by using the joint colortexture histogram to represent a target and then applying it to the mean shift framework. Apart from the conventional color histogram features, the texture features of the object are also extracted by using the local binary pattern (LBP) technique to represent the object. The major uniform LBP patterns are expl...
