Following in the footsteps of the renowned report “Control in an Information Rich World,” Report of the Panel on “Future Directions in Control, Dynamics, and Systems” chaired by Richard Murray (2002), this paper aims to demonstrate that Systems & Control is at the heart of the Information and Communication Technologies to most application domains . As such, Systems & Control should be acknowled...

Soon after the discovery of x-rays by Roentgen, radioactivity by Becquerel, and radium by the Curies, it was concluded that x-rays could not only be used for diagnostic purposes but also for therapy [1,2]. In the early years of radiation therapy, physicians had little understanding or knowledge of the physical nature and biological effects of radiation, the delivered doses were not certain, the...

This paper describes a general method for interactive segmentation, Smart Paint. The user interaction is inspired by the way an airbrush is used, objects are segmented by ”sweeping” with the mouse cursor in the image. The user adds or removes details in 3D by the proposed segmentation tool and the user interface shows the segmentation result in 2D slices through the object. We use the novel met...

in descriptive statistics, there are two computational algorithms for determining the variance s2, of a set of observations : algorithm 1: s2= - , algorithm 2: s2= , where . it is interesting to discuss, which of the above formulas is numerically more trustworthy in machine numbers sets. i this paper, based on total effect of rounding error, we prove that the second algorithm is better than ...

Five carnation cultivars (‘Grand Salam’, ‘Nelson’, ‘Kaly’, ‘Cinderella’ and ‘Tempo’) were evaluated with respect to growth, yield and quality characteristics under lath house conditions at Kala Shah Kaku Research Station, Directorate of Floriculture, Lahore during 2011. Among the cultivars studied, maximum plant height was recorded in carnation cultivar ‘Grand Salam’ (78.66 cm) closely followed...

The grand challenge in global health is the inequality in mortality and life expectancy between countries and within countries. According to Global Health 2035, the Lancet Commission celebrating the 20th anniversary of the World Development Report (WDR) of 1993, the world now has the unique opportunity to achieve a grand convergence in global mortality within a generation. This article comments...

The constantly growing body of scholarly knowledge of science, technology, and humanities is an asset of the mankind. While new discoveries expand the existing knowledge, they may simultaneously render some of it obsolete. It is crucial for scientists and other stakeholders to keep their knowledge up to date. Policy makers, decision makers, and the general public also need an efficient communic...

We derive matter collineations for some static spherically symmetric spacetimes and compare the results with Killing, Ricci and Curvature symmetries. We conclude that matter and Ricci collineations are not, in general, the same.
