A study was conducted to examine the effects of nation-states’ political institutions on state relations. War-fighting and selection-effects explanation were compared to explain why democracies were more likely to win wars. An analysis of all interstate wars between 1816 and 1982 revealed that democracies that initiate wars often win them. Results also suggest that domestic political structure ...
Global fits to precision cosmological data which show that there is a dark energy component comprising about 2/3 of the total cosmological energy also hint that a dark energy with w = P/ρ < −1 is viable, even favored. Here we discuss implications of such a surprising w, including whether it jeopardizes vacuum stability. It appears to be secure in microscopic processes, but why bulk dark energy ...
Investors significantly reduce their future returns by selecting mutual funds with higher fees, allured by higher past returns that do not predict future performance. This suboptimal behavior, which can roughly halve an investor’s retirement savings, is driven by two psychological factors. One factor is difficulty comprehending rate information, which is critical given that mutual fund fees and...
abstract because of the many geopolitical, geo economical and geo strategically potentials and communicational capabilities of eco region, members can expand the convergence and the integration in base of this organization that have important impact on members development and expanding peace in international and regional level. based on quality analyzing of library findings and experts interv...
An explicit snake is a smooth closed curve which deforms towards the desired features in an image. There are two types of force controlling the motion of the snake: internal and external forces. The former usually constrains the snake’s curvature and tension, through first and second Tikhonov smoothness force terms, while the latter generates attraction forces. To investigate the possible role ...
Experimental robot identi cation techniques can principally be divided into two categories, based on the type of models they use: internal or external. Internal models relate the joint torques or forces and the motion of the robot; external models relate the reaction forces and torques on the bedplate and the motion data. This paper describes how internal and external robot models can be combin...
Most robot manipulators are poor at measuring and controlling forces, especially force of contact. At the innermost control loops these force estimates are needed to control compliance. At a more general level identifying when contact occurs, and the forces involved, are elemental requirements in building cognitive information that allow robots to adapt to an unstructured environment. This pape...
Background and purpose: Internal assessment is an introduction for improving the quality and the first step of accreditation. Identifying the competencies and the weaknesses enables the organizations to choose the strategies to face environmental forces. This study aimed to identify the strengths and the weaknesses of hospitals in Gorgan and the Gonbad-e Qabus cities, Iran. Materials and metho...
