A parameterized algebra for event notification services
- Trang 61-63
Event notification services are used in various applications such as digital
libraries, stock tickers, traffic control, or facility management. However to
our knowledge, a common semantics of events in event notification services has
not been defined so far. We propose a parameterized event algebra which
describes the semantics of composite events for event notification systems. The
parameters ser...

Logic Trạng thái Phân tán Dịch bởi AI
- Trang 55-57
Chúng tôi giới thiệu một logic thời gian để lý luận về các ứng dụng toàn cầu.
Trước tiên, chúng tôi định nghĩa một logic mô-đun cho địa phương tính, nhúng các
lý thuyết địa phương của mỗi thành phần vào một lý thuyết về các trạng thái phân
tán của hệ thống. Chúng tôi cung cấp cho logic một hệ thống tiên đề đầy đủ và
chuyên sâu. Sau đó, chúng tôi mở rộng logic với một toán tử thời gian. Đóng góp

A continuous planning framework with durative actions
- Trang 108-114
This paper describes a continuous planning framework to be used by a planning
agent situated within an environment, which reasons about goals with priorities
and deadlines, and actions with duration. The framework assumes that goals may
be generated continuously, which requires the interleaving of planning and
execution. Constraints upon time may mean it is not possible for all goals to be
achieve...

Indexed flows in temporal /spl times/ modal logic with functional semantics
- Trang 146-153
Two classical semantical approaches to studying logics which combine time and
modality are the T /spl times/ W-frames and Kamp-frames (Thomason (1984)). In
this paper we study a new kind of frame that extends the one introduced in
Burrieza et al. (2002). The motivation is twofold: theoretical, i.e.,
representing properties of the basic theory of functions (definability); and
practical, their use i...

Stratified causal theories for reasoning about deterministic devices and protocols
- Trang 52-54
We present a method for formalising the behaviour of simple deterministic
devices and protocols in a way that makes explicit the causal dependencies
amongst the component elements, thereby allowing true causal (as opposed to
purely temporal) reasoning. Our intention is to handle such systems effectively
in the simplest possible way, without invoking additional problematic
considerations (concernin...

Logical data expiration
- Trang 66-67
Summary form only given. Data expiration is an essential component of data
warehousing solutions: whenever large amounts of data are repeatedly collected
over a period of time, it is essential to have a clear approach to identifying
parts of the data no-longer needed and a policy that allows disposing and/or
archiving these parts of the data. Such policies are necessary even if adding
storage to a...

Performance of querying temporal attributes in object-relational databases
- Trang 58-60
We evaluate a model for temporal data utilizing the benefits of
object-relational database systems (ORDBS). In particular we show how attribute
timestamping can be efficiently implemented in state-of-the-art ORDBS. The
attribute timestamping concept is based on introducing user-specific types for
temporal versions of datatypes. Moreover on the physical level we make use of
user-defined index struc...

Evolution specification of multigranular temporal objects
- Trang 78-85
The main key feature of temporal databases is to maintain all values taken by
object attributes over time. Since historical information may be needed at
different levels of detail, multigranular temporal databases have been
introduced, in which different attributes can be stored at different temporal
granularities. An important issue that has not been addressed, however is that
the required level ...
