One of the challenges of requirements engineers is to understand domain issues and elicit requirements effectively. One of the possible strategies is to perform a manual inspection of similar projects to quickly gain leverage of domain concepts underlying the projects. However, this task is time-consuming and limited to the projects at hand. To ensure comprehensive elicitation using more widely...

When software development teams modify their requirements engineering process as an independent variable, they often examine the implications of these process changes by assessing the quality of the products of the requirements engineering process, e.g., a software requirements specification (SRS). Using the quality of the SRS as the dependent variable is flawed. As an alternative, this paper p...

The elicitation of end-user requirements is primarily focusing on the industry, where companies endeavor to discover and satisfy their customer’s requirements. Increasingly however, companies which are working in the same or in different fields are getting together, in order to do joint research and development, despite the fact that they may be potential competitors. These kinds of projects ha...

This paper introduces an approach to multi-perspective requirements engineering (PREview) which has been designed for industrial use and discusses our practical experience in applying PREview. We have developed a flexible model of viewpoints and, using examples from an industrial application, show how this can be used to organise system requirements derived from radically different sources. We ...

Developing a desirable framework for handling inconsistencies in software requirements specifications is a challenging problem. It has been widely recognized that the relative priority of requirements can help developers to make some necessary trade-off decisions for resolving conflicts.

PURPOSE Appropriate caloric intake in critically ill patients receiving enteral nutrition is controversial. This study evaluates the impact of different caloric regimens on severity of organ failure measured with Sequential Organ Failure Assessment (SOFA). MATERIALS AND METHODS We conducted a randomized prospective controlled trial. Study population included adult intensive care unit (ICU) pa...

BACKGROUND AND PURPOSE The local infiltration analgesia (LIA) technique has been widely used to reduce opioid requirements and to improve postoperative mobilization following total hip arthroplasty (THA). However, the evidence for the efficacy of LIA in THA is not yet clear. We determined whether single-shot LIA in addition to a multimodal analgesic regimen would reduce acute postoperative pain...

The paper presents a modelling framework for activity scheduling process. The modelling framework considers Random utility maximization (RUM) assumption for its components in order to dynamically capture the joint activity type, location and continuous time expenditure choice tradeoffs over the course of the day. The dynamics of activity scheduling process are modeled by considering the history...

With the VMS (Variable Message Signs) gradually and extensively used in major cities, it is necessary to develop a related evaluation system to evaluate its guidance effect systematically and efficiently. This paper primarily studies on developing a system to make the evaluation work more simply and quickly, and it chiefly contains the following five aspects: Firstly, conducting the system requ...
