RSS constraintsConstraints for Corpora Development and Validation
White Paper Ideally, the software supporting the creation of a corpus has to allow all the constraints that follow from the guidelines to be imposed over the XML representation of the corpus. This paper considers corpora as a set of... [04 Dec 2008]
Survivable Network Design With Degree or Order Constraints
White Paper This paper presents algorithmic and hardness results for network design problems with degree or order constraints. The paper first considers the SURVIVABLE NETWORK DESIGN problem with degree constraints... [09 Jan 2008]
A UML Precise Specification of Design Patterns Using Decoupling Constraints
White Paper This paper adapts the notion of decoupling constraints to UML models and it expresses it using the Object Constraint Language. Adding decoupling constraints to collaboration templates allows checking if... [03 Dec 2008]
Optimizing IT Security Within Real-World Resource Constraints--A Practical Guide for Mid-Sized Businesses
White Paper While midsized businesses face the same risks as larger enterprises, they tend to have particularly tight IT resource constraints. Their central challenge therefore is not only to protect themselves from potential... [18 Mar 2009]
Optimal Replica Placement in Tree Networks With QoS and Bandwidth Constraints and the Closest Allocation Policy
White Paper The latter problem is investigated using the Closest access policy when adding QoS and bandwidth constraints. This paper deals with the replica placement problem on fully homogeneous tree networks known as the Replica... [11 Jul 2008]
Circuit-Switched "Network Capacity" Under QoS Constraints
White Paper Then choices of routes and of admission control policies are sought to achieve maximum throughput (usually under QoS constraints). However, similarly to the notion of channel "Capacity," it is also of interest to... [10 Sep 2008]
The IBM Research Constraint Solver Models and Solves Complex Problems Through the Examination and Prioritization of Myriad Variables and Constraints
White Paper The Constraint Solver models and solves problems involving thousands of variables and multi-tiered constraints. Variables can be a headache. Ask any seventh grader puzzling over a2=9. When variables for a given problem... [11 Jun 2008]
Enforce Business Rules for All Your Data With Constraints
White Paper Of the several ways to enforce business rules in the database, only constraints can guarantee that the business rules are always enforced for all the data. This paper teaches how to apply foreign key... [11 Jul 2007]
IP Network Design With End-to-End QoS Constraints: The VPN Case
White Paper The challenge in the area is how to devise reasonable packet network design methodologies that allow the choice of the most adequate set of network resources, subject to e2e QoS constraints and, at the same time,... [12 Jan 2008]
XML Constraints: Specification, Analysis, and Applications
White Paper To make effective use of XML constraints it is often necessary to reason about them, both at compile-time (for consistency and implication analyses) and at run-time (for incremental constraint checking). [29 Nov 2006]
Orchestrating Composite Web Services Under Data Flow Constraints
White Paper This paper proposes a solution for orchestrating composite web services under data flow constraints. To overcome data flow constraints, each partition is executed within the same domain as the... [05 Feb 2009]
Sizing HP ProLiant and BladeSystem 64-Bit Servers for Exchange 2007 and Large Mailbox Storage Constraints
White Paper This paper provides sizing information for running Microsoft Exchange Server 2007 mailbox servers on HP ProLiant servers with large mailbox storage constraints. The sizing tables and charts presented here show the... [08 May 2007]
Optical Network Design With Optical Constraints in IP/WDM Network
White Paper This paper considers algorithms for the logical topology design and traffic grooming problem in WDM networks with router interface constraints as well as optical constraints. The optical... [12 Jan 2008]
Using UML to Visualize Role-Based Access Control Constraints
White Paper The constraints of the RBAC model are expressed using the Object Constraint Language (OCL). OCL constraints, based on first-order logic, are difficult to understand. To alleviate this problem, the paper... [03 Dec 2008]
Addressing Budget Constraints Through Testing
White Paper CIOs and IT Managers need to address this sooner rather than later as for many, key delivery targets still need to be achieved regardless of budgetary constraints. The increasing unrest of the economic climate is... [10 Jul 2009]
