2. A heuristic approach to modelling thinnings

Author

Subjects
Forestry, SD1-669.5
Abstract

Thinnings play an important role in guiding forest development and are considered by many to be the most important influence on forests in Central Europe. Due to their importance, thinning models are a major part of any forest growth model for managed forests. Existing thinning model approaches have a number of problems associated with structure and model development that weaken their reliability and accuracy. To overcome some of these problems this paper proposes a heuristic approach to modelling thinnings, where the focus is on distance-dependent, single-tree models. This alternative approach tries to capture the information, strategies and deductive processes likely to be employed by a forester deciding on the removal of individual trees in a stand. Use of heuristics to represent thinning knowledge simplifies the construction and refinement of a thinning model and increases its plausibility. The representation of thinning heuristics in Prolog â a programming language based on formal logic â is a straightforward process without losing expressiveness of the original heuristics. Limited tests of the model implemented in Prolog indicate that the proposed model outperforms its competitors.

20. OpenKnowledge for Peer-to-peer Experimentation in Protein Identification by MS/MS

Author

Abstract

Abstract Background Traditional scientific workflow platforms usually run individual experiments with little evaluation and analysis of performance as required by automated experimentation in which scientists are being allowed to access numerous applicable workflows rather than being committed to a single one. Experimental protocols and data under a peer-to-peer environment could potentially be shared freely without any single point of authority to dictate how experiments should be run. In such environment it is necessary to have mechanisms by which each individual scientist (peer) can assess, locally, how he or she wants to be involved with others in experiments. This study aims to implement and demonstrate simple peer ranking under the OpenKnowledge peer-to-peer infrastructure by both simulated and real-world bioinformatics experiments involving multi-agent interactions. Methods A simulated experiment environment with a peer ranking capability was specified by the Lightweight Coordination Calculus (LCC) and automatically executed under the OpenKnowledge infrastructure. The peers such as MS/MS protein identification services (including web-enabled and independent programs) were made accessible as OpenKnowledge Components (OKCs) for automated execution as peers in the experiments. The performance of the peers in these automated experiments was monitored and evaluated by simple peer ranking algorithms. Results Peer ranking experiments with simulated peers exhibited characteristic behaviours, e.g., power law effect (a few dominant peers dominate), similar to that observed in the traditional Web. Real-world experiments were run using an interaction model in LCC involving two different types of MS/MS protein identification peers, viz., peptide fragment fingerprinting (PFF) and de novo sequencing with another peer ranking algorithm simply based on counting the successful and failed runs. This study demonstrated a novel integration and useful evaluation of specific proteomic peers and found MASCOT to be a dominant peer as judged by peer ranking. Conclusion The simulated and real-world experiments in the present study demonstrated that the OpenKnowledge infrastructure with peer ranking capability can serve as an evaluative environment for automated experimentation.

22. THE DENSITY DOLDRUMS.

Abstract

This article explores the issue of density and its impact on housing affordability in Calgary. It presents various perspectives on the topic, with some individuals expressing concerns about the effects of increased density on the environment and personal space, while others argue that higher density is necessary to address the city's housing crisis. The article acknowledges the emotional responses that density can evoke, including fear, disappointment, and optimism. It emphasizes the need for effective communication and community engagement to address these emotions and find solutions that balance the needs of different stakeholders. The Handbook provides strategies for professional planners to improve community dialogue, connect with residents, and change the language used in urban planning. The author, Goldstein, emphasizes the importance of empathy in the planning profession and suggests that Calgarians should also be more empathetic and reevaluate their beliefs, such as the strong ownership model in North America. Goldstein argues that different generations have different demands from cities, and it is important to listen to and appreciate the opinions of those who have had limited influence in the past. The article concludes by suggesting that even if one may not agree with new forms of housing or densification, it is important to understand their significance for a growing city like Calgary.
