A revived interest in space communication has been initiated by major space agencies since the early of this millennium. Globally, a significant growth of national space programs has been achieved by a number of nations including the USA, Europe, Russia, India and China. Industrially, there is a trend for privatizing the space industry. This will lead to new space communication age opening new ...

This paper reports supporting dynamic transport selection in omniORB2, which is a CORBA 2.0 compliant CORBA system that has been developed at AT&T Laboratories, Cambridge. We describe our design and implementation of supporting dynamic transport protocol selection in our system, and some initial experiments with the system. In our approach, IIOP can be selected for ensuring interoperability bet...

Atomic Broadcast (where all processes deliver broadcast messages in the same order) is a very useful group communication primitive for building fault-tolerant distributed systems. This paper presents an atomic broadcast protocol that can be claimed to be optimal in terms of failure detection, resilience, and latency. The protocol requires only the weakest of the useful failure detectors for liv...

This study was designed to clarify the association between inter-episode bipolar disorder (BD) and sleep architecture. Participants completed a baseline symptom and sleep assessment and, 3 months later, an assessment of symptoms and impairment. The effects of psychiatric medications on sleep architecture were also considered. Participants included 22 adults with BD I or II (inter-episode) and 2...

Dynamic inter-organizational business processes are necessary to enable the flexible creation of partnerships in areas such as e-commerce and supply-chain-management. Although many information system architectures for the support of static inter-organizational business processes exist, such architectures are still not available for supporting dynamic inter-organizational business processes. In ...

The title complex, [NiCl(2)(C(15)H(24)N(6))(C(3)H(7)NO)], is isomorphous with the Co(II) analogue. Three N-atom donors from the facially coordinating triaza macrocyclic ligand, one O-atom donor from dimethyl-formamide and two Cl(-) anions surround the Ni(II) ion in a distorted octa-hedral coordination geometry. Inter-molecular C-H⋯Cl and C-H⋯N hydrogen-bonding inter-actions link the complex mol...

The title compound, [PdBr(2)(C(24)H(31)P)(2)], has a distorted trans square-planar coordination of the Pd atom, which occupies an inversion centre. The most important bond distances include Pd-P of 2.380 (2) Å and Pd-Br of 2.515 (2) Å. Weak inter-molecular π-π inter-actions between the benzene rings of adjacent mol-ecules [centroid-centroid distance = 3.949 (6) Å] are present via crystallograph...

The title compound, C14H13N3O3·H2O, adopts an E conformation with respect to the azomethine bond and crystallizes in the amide form. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, the lattice water molecule plays a major role in the supramolecular architecture by interconnecting adjacent molecules into a three-dimensional netwrok by means of O-H⋯O, O-H⋯N and N-H⋯O hydrogen-bondi...

In the title compound, C(6)H(7)IN(2), the non-H atoms of the mol-ecule are located on a crystallographic mirror plane; the H atoms of the methyl groups are therefore disordered over two positions of equal occupancy. In the crystal structure, short inter-molecular I⋯N contacts [3.390 (3) Å] are found, linking the mol-ecules into zigzag chains. In addition, there are inter-molecular π-π stacking ...
