Proper management of requirements is crucial to successful development software within limited time and cost. Nonfunctional requirements (NFR) are one of the key criteria to derive a comparison among various software systems. In most of software development NFR have be specified as an additional requirement of software. NFRs such as performance, reliability, maintainability, security, accuracy ...

We describe a flexible web service selection model that will rate the web services based on Quality of Service (QoS) constraints. To maintain the QoS factors the non functional requirements (NFR) of a web service such as response time, throughput, reliability and security are crucial during web service selection. The performance depends not only on satisfying functional requirements, but also f...

Physiological reactions to noxious stimuli are often used to make inferences about pain, but few studies have thoroughly examined the intra- and interindividual relationships between them. In the present study (N=104), multilevel analyses was used to assess relations between physiological (nociceptive flexion reflex magnitude [NFR], blink reflex magnitude, skin conductance response [SCR], heart...

Emotion can modulate pain and spinal nociception, and correlational data suggest that cognitive-emotional processes can facilitate wind-up-like phenomena (ie, temporal summation of pain). However, there have been no experimental studies that manipulated emotion to determine whether within-subject changes in emotion influence temporal summation of pain (TS-pain) and the nociceptive flexion refle...

Although Non-Functional Requirements (NFR) have been present in many software development methods, they have been faced as a second or even third class type of requirement, frequently hided inside notes and therefore frequently neglected or forgotten. Surprisingly, despite the fact that nonfunctional requirements (NFR) are among the most expensive and difficult to deal with [5] [12] [3][10], ev...

Non-functional requirements (NFR) have a crucial role in the software development process because they correspond to the characteristics and restrictions on which the software must running and represent factors that influence the time and cost of software development. Nevertheless, many organizations do not perform these requirements elicitation properly. This paper presents an approach to crea...

The nociceptive flexion reflex (NFR) is a polysynaptic withdrawal reflex typically assessed from biceps femoris electromyogram (EMG) following noxious stimulation of the ipsilateral sural nerve. Electrophysiological evidence suggests the reflex is elicited following the activation of small diameter A-delta afferents. As a result, the NFR is assumed to be a categorically distinct construct that ...

PURPOSE This study aims to establish the prevalence of high work-related fatigue (need for recovery, NFR) among employees and to explain group differences categorized by gender, age, and education. The study particularly aims to clarify prevalence and explanatory factors in highly educated women. METHODS In 2005 and 2006, large representative samples of 80,000 Dutch employees (net response ra...

UNLABELLED Sex differences in the processing and experience of emotion exist. The present study examined whether sex differences in emotion lead to sex differences in affective modulation of pain and spinal nociception (assessed by nociceptive flexion reflex, NFR). Participants were healthy men (n = 47) and women (n = 73). Prior to affective modulation testing, electrocutaneous pain sensitivity...

PURPOSE To investigate the impact of increasing age on the need for recovery (NFR) over time among day workers METHODS The study is based on data from the first 2 years of follow-up of the Maastricht Cohort Study (n = 7,734). To investigate whether age predicted the onset of elevated NFR, multivariate survival analyses were conducted RESULTS The highest levels of NFR were observed in the ag...
