For long-term operations, graph-based SLAM approaches require to marginalize nodes in order to control the computational cost. In this paper, we present a method to recover a set of nonlinear factors that best represents the marginal distribution in terms of Kullback-Leibler divergence. The proposed method, which we call nonlinear factor recovery (NFR), estimates both the mean and the informati...

Non-Functional Requirements (NFRs) have been increasingly accepted as crucial to the success of software projects. However, the current state of industrial practice is still focusing mainly on functional requirements (FRs) using UML use cases as the main tool for requirements elicitation and modeling. In order to encourage practitioners to focus more on much deserved NFRs, there is a need for f...

Research suggests that emotion modulates spinal nociception and pain; however, there is limited evidence that other objective, nociceptive reactions are modulated. This study examined the impact of affective picture-viewing on autonomic reactions (skin conductance response, heart rate acceleration) resulting from noxious electric stimulations to the sural nerve. Pictures varying in affective va...

Studying the quality requirements (aka Non-Functional Requirements (NFR)) of a system is crucial in Requirements Engineering. Many software projects fail because of neglecting or failing to incorporate the NFR during the software life development cycle. This paper focuses on analyzing the importance of the quality requirements attributes in software effort estimation models based on the Desharn...

Traditionally, non-functional requirements (NFRs) are specified as measurable entities to permit evaluation satisfaction; however, NFR specifications quickly become obsolete because (1) NFRs are expressed in numbers, (2) architects specify them using the correct values at design time, and/or (3) providers are constantly improving their offer, in terms of functionality and quality of service (Qo...

Web Services (WS) have become one the most used technologies nowadays in software systems. Among the challenges when integrating WS in a given system, requirementsdriven selection occupies a prominent place. A comprehensive selection process needs to check compliance of Non-Functional Requirements (NFR), which can be assessed by analysing WS Quality of Service (QoS). In this paper, we describe ...

Abstract The steady-state nonlinear forced response (NFR) of finite element (FE) models with friction joints is usually computed in the frequency domain through combination node-to-node contact elements and Harmonic Balance Method (HBM). In current state art, rare are cases where forces estimated for interfaces non-conforming mesh grids. This need nowadays taking place due to improving capabili...

Pepper plants are subject to complex environmental factors including abiotic and biotic stresses in fields, as well the significant effects of climate changes, low high temperatures. Low temperature stress growth development pepper is one most critical issues, directly impacts crop yield productivity plants. Therefore, it essential select breed temperature-(LT) tolerant (Capsicum annuum L.) cul...

Abstract Self-adaptive systems (SASs) are increasingly leveraging autonomy in their decision-making to manage uncertainty operating environments. A key problem with SASs is ensuring requirements remain satisfied as they adapt. The trade-off analysis of the non-functional (NFRs) establish balance among them. Further, when performing trade-offs it necessary know importance each NFR be able resolv...

OBJECTIVE To describe the reasons for, and immediate outcome following Medical Emergency Team (MET) activation. METHODS Retrospective analysis of MET calls in 1998. RESULTS There were 713 MET calls to 559 in-patients. Of the 559 patients 252 (45%) were admitted to ICU and 49 (6.9%) died during the MET response. The three commonest criteria for calling the MET were a fall in GCS>2 (n=155); a...
