This paper develops a framework of a theory for the emergence of social reality that turns out by relating three different models or agent architectures, respectively: a model of the emergence of social hierarchies, an architecture of a normative system and an architecture of the delegation of social control. This reflects a complex feedback loop of the emergence of an autonomous sphere of soci...

Star trackers provide spacecraft with the most precise estimate of their orientation,or attitude, with respect to a fixed celestial coordinate system. The star tracker camera views a patch of the celestial sphere and attempts to recognize the stars contained within. Then from the known star positions it will calculate the attitude. A number of pattern recognition methods, each with various stre...

In this paper we present the design of a sliding mode controller for attitude control of spacecraft actuated by three orthogonal reaction wheels. The equilibrium of the closed loop system is proved to be asymptotically stable in the sense of Lyapunov. Due to cases where spacecraft do not have angular velocity measurements, an estimator for the generalized velocity is derived and asymptotic stab...

Boltzmann defined the entropy of a macroscopic system in a macrostate M as the log of the volume of phase space (number of microstates) corresponding to M. This agrees with the thermodynamic entropy of Clausius when M specifies the locally conserved quantities of a system in local thermal equilibrium (LTE). Here we discuss Boltzmann's entropy, involving an appropriate choice of macro-variables,...

British colonial policies set the stage for the subsequent balance between state and civil society in Malaysia, including the persistent racial stratification of the public sphere, cross-racial differences in modes of state–society engagement and the focus on development of citizenship skills for some groups and autonomous self-regulation for others. This article explores the vestiges and impli...

This paper addresses the problem of performing navigation with a mobile robot using active vision exploring the image sphere properties in a stereo divergent configuration. The navigational process is supported by the control of the robot’s steering and forward movements j u s t using visual information as feedback. The steering control solution is based o n the diflerence between signals of vi...

This paper addresses the problem of performing navigation with a mobile robot using active vision exploring the image sphere properties in a stereo divergent configuration. The navigational process is supported by the control of the robot's steering and forward movements just using visual information as feedback. The steering control solution is based on the difference between signals of visual...

see through the wall radar, is a relatively new small range radar that uses electromagnetic waves to detect targets behind wall. because of its symmetry, a conducting sphere is often used as a reference scatterer to calibrate radars. in this paper, to simulate received signal for see through the wall radar, scattering model of a conducting sphere in free space is presented. then using a dielect...

This paper presents SPHERE, a project aimed at the realization of an integrated framework to abstract hardware complexity interconnected, modern system-on-chips (SoC) and simplify management their heterogeneous computational resources. The SPHERE leverages hypervisor technology virtualize resources isolate behavior different subsystems running on same platform, while providing safety, security,...

The concept of "public sphere”, which has been one the main discussion topics academy since 1980s, derives its basis from Jürgen Habermas' Structural Transformation Publicity, published in 1962. bourgeoisie, whose influence increased European society, creates a public community places such as halls, cafes, and clubs where it had critically discussed 18th century, this spread to with increase pu...
