Third-party reviews play an important role in many contexts in which tangible attributes are insufficient to enable consumers to evaluate products or services. In this paper, we examine the impact of professional and amateur reviews on the box office performance of movies. Using a simple diffusion model, we establish an econometrics framework to control for the interaction between the unobserva...

Morphological openings and closings form the cornerstones of a rich set of nonlinear operators in signal processing. In this paper, we show how a new morphological operator can be constructed that serves as an approximation to openings and closings for images corrupted by low levels of noise. 2001 Elsevier Science B.V.

The discovery and subsequent study of microquasars lead to major progress in our understanding of: 1) the nature of relativistic jets seen elsewhere in the universe, and 2) the connection between the accretion onto compact objects and the formation of collimated jets. A detailed account of the major progress accomplished until present was published in Annual Review of Astronomy & Astrophysics (...

Determination of stomatal densities of the banana peel (Musa acuminata L. var Hort. Valery) by microscopic observations showed 30 times fewer stomates on fruit epidermis than found on the banana leaf. Observations also showed that peel stomates were not laid down in a linear pattern as on the leaf.It was demonstrated that stomatal responses occurred in banana fruit. Specific conditions of high ...

As Semantic Web services begin to emerge as the next evolution of the Service Oriented Architecture, it is become clear that authorization is going to be one of its biggest challenges. Not only are there the typical obstacles which most areas of Semantic Web services have had to overcome, i.e. what parts of a Web services need semantic information, how best to use the semantics, and agreeing on...

Purpose The review aims to facilitate a broader understanding of platform opening and cooperation points out potential research directions for scholars. Design/methodology/approach This study searches Web Science (WOS) database relevant literature published between 2010 2021 selects 86 papers this review. selected is categorized according three dimensions: the strategic choice (before opening),...

This research examines the strengthening efficiency of prestressed concrete dapped end beam with opening under monotonic point load. The study concerns position relative to end, shape opening, as circle or square, in addition, effect CFRP around opening. experimental program consisted testing nine scaled down specimens single near end. Beam one control and remaining eight beams classified into ...
