NB: A UK species action plan already exists for the Scottish Crossbill in the UK Biodiversity Action Plan. This document aims to put this information into a European framework. Reviews This action plan should be reviewed and updated every four years. An emergency review will be undertaken if sudden major environmental changes, liable to affect the population, occur within the species' range. Sh...
چکیده به منظور مطالعه مرز سنومانین-تورونین در زون های زمین ساختی ایران مرکزی و کپه داغ سه برش چینه شناسی در این نواحی انتخاب و از آنها نمونه برداری به عمل آمد. در ناحیه ایران مرکزی برش کلاه قاضی و در ناحیه کپه داغ برش های گردنه مزدوران و طاهرآباد ترک انتخاب گردیده اند. مطالعات زیست چینه نگاری بر روی فرامینیفرهای موجود نشان می دهد که برش های ناحیه کپه داغ در بر گیرنده سازندهای آیتامیر و آب در...
Planning by Rewriting (PbR) is a paradigm for efficient high-quality planning that exploits declarative plan rewriting rules and efficient local search techniques to transform an easy-to-generate, but possibly suboptimal, initial plan into a high-quality plan. In addition to addressing planning efficiency and plan quality, PbR offers a new anytime planning algorithm. The plan rewriting rules ca...
To investigate the feasibility of image-based intracavitary brachytherapy (IBICBT) for uterine cervical cancer, we evaluated the dose-volume histograms (DVHs) for the tumor and organs at risk (OARs) and compared results from the IBICBT plan and the standard Manchester system (Manchester plan) in eight patients as a simulation experiment. We performed magnetic resonance imaging (MRI) and compute...
The ability of a planner to reuse parts of old plans is hypothesized to be a valuable tool for improving eeciency of planning by avoiding the repetition of the same planning eeort. We test this hypothesis from an analytical and empirical point of view. A comparative worst-case complexity analysis of generation and reuse under diierent assumptions reveals that it is not possible to achieve a pro...
PURPOSE Develop a decision support tool that aids dosimetrists, physicians, and physicists in assessing and improving plan quality through comparison to plans previously used in similar clinical situations. METHODS Software was developed to capture and store DVHs and other clinically relevant treatment plan characteristics in a database. In addition to the plan DVH, the database contains a to...
