Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging
We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of simultaneity
Cooperative Processing: An Agenda for Research
The purpose of this paper is to explore the potential research agenda for Cooperative Processing (COP). COP is a method of processing in which communications is an integral part of the process of executing an application. Numerous innovative products that support COP are starting to appear on the market. However, as is usually the case with any new technology, many organizations have not yet implemented COP. They have embraced a wait and see attitude. Such a stance can be attributed to the newness of the applications operating in COP mode and to the lack of data demonstrating COP\u27S uses and benefits. For example, no data, at present, demonstrates basic COP efficacy. Among many possible research areas this paper suggests topics such as: potential COP users, types of applications benefiting from the COP processing mode, and organizational and technological factors involved in COP implementation
Visual Process Language: An Environment That Enhances Inventiveness in the System Development Process -- a Theoretical Perspective
This paper provides a theoretical perspective on the effect of computer support on creativity. The assertion is made that artifacts of IS do not substantially differ from those of art and science, and that the creative processes leading to the artifacts are similar. It further proposes that the use of newly available computer technology, specifically, the Visual Process Language (VPL) will have much to offer in terms of augmenting creativity when constructing IS artfacts. We postulate that VPL assists the first insight, preparation and illumination steps of the creative process, and that both Association/Images and Progressive Abstraction techniques are embedded in VPL
The characteristic exponents of the falling ball model
We study the characteristic exponents of the Hamiltonian system of () point masses freely falling in the vertical half line
under constant gravitation and colliding with each other and
the solid floor elastically. This model was introduced and first studied
by M. Wojtkowski. Hereby we prove his conjecture: All relevant characteristic
(Lyapunov) exponents of the above dynamical system are nonzero, provided that
(i. e. the masses do not increase as we go up) and
Mediatization of Politics During U.S. Presidential Election 2008
The thesis of this paper applies to the mediatization of politics process during American
presidential campaign of 2008. It is entrenched in the theory of political communication.
Because of the primary assumptions in the analysis below, political communication is
considered mainly from perspective of the models of relations between the mass media
and politics, which are treated as systems. It is justified because those relations influence
the abovementioned systems and play the biggest role in affecting mass society and culture.
In this thesis, the public is considered as having less influence on entire process of political
communication.
In order to clarify the subject of the research, the division into structural and functional
mediatization was created. Structural mediatization, which is the main subject of
the analysis, occurs when structures of the media and political systems come into dependence
and subordination relation. Parts of the media system dominate over the analogical
elements in the political system, internalizing media logic. Individual elements of the
political world comply to the media logic and the media orders. Subjects of the political
system implement political marketing methods to use the dominant role of the media in
the process. Functional mediatization can be defined as a transfer of systemic relations at
the smallest possible level – specific case in micro scale,when the medium controls a political
actor. Here, the mediatization takes its most radical form. The medium on every
