T T T T T T T T T T T T T T T Abstract In this paper we continue an earlier study of ends non-compact manifolds. The over-arching goal is to investigate and obtain generalizations of Siebenmann's famous collaring theorem that may be applied to manifolds having non-stable fundamental group systems at infinity. In this paper we show that, for mani-folds with compact boundary, the condition of inw...

The Intelligent Street is a music installation that is able to respond intelligently to the collective requests of users interacting together. The performance it creates is largely influenced by the collective set of text commands from users’ mobile phones. In this way, users in shared environments, subjugated for so long to uncontrollable and often undesired ‘Muzak’, can now directly influence...

In the United Kingdom the Environment Agency of England and Wales have developed a number of initiatives to assist in implementing the Water Framework Directive (2000/60/EC) including Catchment Management Strategies (CAMSs) and the Resource Assessment Management (RAM) Framework. These processes include setting river flow objectives and establishing best practice for the assessment of water reso...

No completely reliable echocardiographic technique has been described for the separate identification of the aorta and main pulmonary artery in complete transposition of the great arteries. A mechanical wide-angle (60 degrees) sector scanner has been applied to this problem in 17 infants and young children, including 8 newborns before angiocardiography. In all patients a longitudinal scan (sagg...

Trench is connected to very narrow and deep excavation filled with bentonite suspension. This paper presents estimation of its stability in cohesive soil. The stability is assessed by two calculation methods. The first involves the equilibrium of forces acting on the rigid wedge. The second one includes numerical calculations conducted in Plaxis 3D Foundations. A few examples having different d...

Major characteristics Many autistic infants are different from birth. Two common characteristics they may exhibit include arching their back away from their caregiver to avoid physical contact and failing to anticipate being picked up (i.e., becoming limp). As infants, they are often described as either passive or overly agitated babies. A passive baby refers to one who is quiet most of the tim...

This paper looks at the convergence of knowledge management and Enterprise 2.0 and describes the possibilities for an over-arching exchange and transfer of knowledge in Enterprise 2.0. This will be underlined by the presentation of the concrete example of T-System Multimedia Solutions (MMS), which describes the establishment of a new enterprise division "IG eHealth". This is typified by the dec...

The Conservation of Energy plays a pivotal part in the development of the physical sciences. With the growth of computation and the study of other discrete token based systems such as the genome, it is useful to ask if there are conservation principles which apply to such systems and what kind of functional behaviour they imply for such systems. Here I propose that the Conservation of Hartley-S...

The lyssomanine jumping spider genus Sumakuru gen. n. is here described for Sumakuru bigal sp. n., from the Bigal River Biological Reserve in Ecuador. Known from a single male, the embolus of the palp takes the form of a smoothly arching curve, and appears fully mobile, being connected to the tegulum by a thin sclerite and a twisted hematodocha. Data from four gene regions (28S, 16SND1, CO1, wi...

The face stability of shallow tunnels was investigated with small-scale model experiments at single gravity. Aim of the research was to detect the evolution of failure mechanisms in dense and loose soil samples with varying overburden above the tunnel. Moreover, the quality of proposed theoretical/numerical approaches for the determination of a necessary support pressure pf was assessed. The re...
