When implementing a product configuration system in a company making complex and highly engineered products, many decisions need to be made in the early phases of the project. This article presents a framework for supporting the initial scoping process and discusses experiences from applying the framework in an engineering company. The framework covers a number of topics, such as identifying th...

BACKGROUND The self-controlled case series (SCCS) is a useful design for investigating associations between outcomes and transient exposures. The SCCS design controls for all fixed covariates, but effect modification can still occur. This can be evaluated by including interaction terms in the model which, when exponentiated, can be interpreted as a relative incidence ratio (RIR): the change in ...

10.1136/bmjopen-2016-015415.89 Background and aims: It is difficult to find a commonly agreed upon definition for Very Important Persons (VIPs) or VIP patients as the concept has minimal representation in the medical literature. Caring for VIP patients, however, can challenge standard professional routines and approaches to healthcare delivery, can affect staff ’s professionalism, and may be di...

Often product line engineering is treated similar to the waterfall model in traditional software engineering, i.e., the different phases (scoping, analysis, architecting, implementation) are treated as if they could be clearly separated and would follow each other in an ordered fashion. However, in practice strong interactions between the individual phases become apparent. In particular, how im...

Scalability is of paramount importance in the design of reliable multicast transport protocols , and requires a careful consideration of a number of problems such as feedback implosion, retransmission scoping, distributed loss recovery, and congestion control. In this paper, we present a reliable multicast architecture that invokes active services at strategic locations inside the network to co...

During the past decade a number of methods and techniques for software product line scoping have been developed. Although their basic goal is the same, when it comes to details it is often hard to see what they have in common, where they differ and what their strengths and weaknesses are. This makes it difficult for the user to decide when and how to use them because these methods and technique...

We describe a language-independent theory for name binding and resolution, suitable for programming languages with complex scoping rules including both lexical scoping and modules. We formulate name resolution as a two-stage problem. First a language-independent scope graph is constructed using language-specific rules from an abstract syntax tree. Then references in the scope graph are resolved...

Product Line (PL) Engineering focuses on the development of complete system families as opposed to single systems. Systems are built of a reusable platform common to the whole family, and of specific parts extending it. The benefits of short time-to-market and lower development costs for each system within the system family are achieved by reusing the platform for each new system to be develope...
