16 May 1999TL;DR: A case study of what indeed turned out to be the most difficult part of a geographically distributed software project, i.e., integration, and shed light on the problems and mechanisms underlying the coordination needs of development projects generally, be they co-located or distributed.
Abstract: It is widely acknowledged that coordination of large scale software development is an extremely difficult and persistent problem. Since the structure of the code mirrors the structure of the organization, one might expect that splitting the organization across time zones, cultures, and (natural) languages would make it difficult to assemble the components. This paper presents a case study of what indeed turned out to be the most difficult part of a geographically distributed software project, i.e., integration. Coordination problems were greatly exaggerated across sites, largely because of the breakdown of informal communication channels. The results imply that multi-site development can benefit to some extent from stable plans, processes, and specifications. The inherently unpredictable aspects of projects, however, require communication channels that can be invoked spontaneously, by developers, as needed. These results shed light on the problems and mechanisms underlying the coordination needs of development projects generally, be they co-located or distributed.

TL;DR: In this article, organic thin-film transistors have been shown to have suitable properties for use in gas sensors, such sensors possess sensitivity and reproducibility in recognizing a range of gaseous analytes.
Abstract: We show that organic thin-film transistors have suitable properties for use in gas sensors. Such sensors possess sensitivity and reproducibility in recognizing a range of gaseous analytes. A wealth of opportunities for chemical recognition arise from the variety of mechanisms associated with different semiconductor–analyte interactions, the ability to vary the chemical constitution of the semiconductor end/side groups, and also the nature of the thin-film morphology.

TL;DR: In this article, a novel method for the optical generation and distribution of millimetre waves is described, which is demonstrated at 36 GHz and an electrical linewidth limited by the resolution bandwidth of the spectrum analyser is achieved.
Abstract: A novel method for the optical generation and distribution of millimetre waves is described. The method is demonstrated at 36 GHz and an electrical linewidth limited by the resolution bandwidth of the spectrum analyser is achieved. No broadening of the electrical linewidth could be observed after propagation through 8 km of standard fibre.

TL;DR: It is suggested that in addition to regulating the shape, micropatterned frameworks act as sites for stress and impurity release during the amorphous-to-crystalline transition.
Abstract: Micropatterning of single crystals for technological applications is a complex, multistep process. Nature provides alternative fabrication strategies, when crystals with exquisite micro-ornamentation directly develop within preorganized frameworks. We report a bio-inspired approach to growing large micropatterned single crystals. Micropatterned templates organically modified to induce the formation of metastable amorphous calcium carbonate were imprinted with calcite nucleation sites. The template-directed deposition and crystallization of the amorphous phase resulted in the fabrication of millimeter-sized single calcite crystals with sub-10-micron patterns and controlled crystallographic orientation. We suggest that in addition to regulating the shape, micropatterned frameworks act as sites for stress and impurity release during the amorphous-to-crystalline transition. The proposed mechanisms may have direct biological relevance and broad implications in materials synthesis.

04 Dec 2007TL;DR: Key requirements for co-channel operation of femtocells such as auto-configuration and public access are discussed and a method for power control for pilot and data that ensures a constant femtocell radius in the downlink and a low pre-definable uplink performance impact to the macrocells is proposed.
Abstract: In this paper, the feasibility of user deployed femtocells in the same frequency band as an existing macrocell network is investigated. Key requirements for co-channel operation of femtocells such as auto-configuration and public access are discussed. A method for power control for pilot and data that ensures a constant femtocell radius in the downlink and a low pre-definable uplink performance impact to the macrocells is proposed, and the theoretical performance of randomly deployed femtocells in such a hierarchical cell structure is analysed for one example of a cellular UMTS network using system level simulations. The resulting impact on the existing macrocellular network is also investigated.
