Functional Documents for Computer Systems
Although software documentation standards often go into great detail about the format of documents, describing such details as paragraph numbering and section headings, they fail to give precise descriptions of the information to be contained in the documents. This paper does the opposite; it defines the contents of documents without specifying their format or the notation to be used in them. W...
متن کاملchannel estimation for mimo-ofdm systems
تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...
Database Systems for Structured Documents
Documents stored in a database system can have complex internal structure described by languages such as SGML. How to take advantage of this structure presents challenges for database system implementors. We classify the types of queries that need to be supported by SGML-conformant database systems. We then describe several data models that have been proposed for representing documents in a dat...
متن کاملA Petri-net based modeling tool, for analysis and evaluation of computer systems
Petri net is one of the most popular methods in modeling and evaluation of concurrent and event-based systems. Different tools have been created to support modeling and simulation of different extensions of Petri net in different applications. Each tool supports some extensions and some features. In this work a Petri net based modeling and evaluation tool is presented that not only supports dif...
متن کاملExtensible layout in functional documents
Highly customised variable-data documents make automatic layout of the resulting publication hard. Architectures for defining and processing such documents can benefit if the repertoire of layout methods available can be extended smoothly and easily to accommodate new styles of customisation. The Document Description Framework incorporates a model for declarative document layout and processing ...
