Integrating human-computer interaction (HCI) activities in software engineering (SE) processes is an often-expressed desire. Two metrics to demonstrate the impact of integrating HCI activities in SE processes are proposed. Usability Goals Achievement Metric (UGAM) is a product metric that measures the extent to which the design of a product achieves its user-experience goals. Index of Integration (IoI) is a process metric that measures the extent of integration of the HCI activities in the SE process. Both the metrics have an organizational perspective and can be applied to a wide range of products and projects. An attempt has been made to keep the metrics easy to use in the industrial context. While the two metrics were proposed mainly to establish a correlation between the two and thereby demonstrate the effectiveness of integration of HCI in SE processes, several other applications seem likely. The two metrics were evaluated in three independent studies: a classroom-based evaluation with two groups of students, a qualitative feedback from three industry projects, and a quantitative evaluation using 61 industry projects. The metrics were found to be useful, easy to use, and helpful in making the process more systematic. Our studies showed that the two metrics correlate well with each other and that IoI is a good predictor of UGAM. Regression analysis showed that IoI has a somewhat greater effect on UGAM in projects that use the agile process model than the waterfall process and in the projects that are executed as a contracted software development service than in the projects in product companies. UGAM also correlated well with the traditional usability evaluations. © 2010 Elsevier Inc. All rights reserved. Source

In this paper, the bending and free flexural vibration behavior of sandwich plates with carbon nanotube (CNT) reinforced facesheets are investigated using QUAD-8 shear flexible element developed based on higher-order structural theory. This theory accounts for the realistic variation of the displacements through the thickness, and the possible discontinuity in slope at the interface, and the thickness stretch affecting the transverse deflection. The in-plane and rotary inertia terms are considered in the formulation. The governing equations obtained using Lagrange's equation of motions are solved for static and dynamic analyses considering a sandwich plate with homogeneous core and CNT reinforced face sheets. The accuracy of the present formulation is tested considering the problems for which solutions are available. A detailed numerical study is carried out based on various higher-order models deduced from the present theory to examine the influence of the volume fraction of the CNT, core-to-face sheet thickness and the plate thickness ratio on the global/local response of different sandwich plates. © 2014 Elsevier Ltd.

The embodiment of the present invention provides a computer implemented network centric system and method for real-time traffic offloading belonging to a plurality of subscribers from a cellular network to a Wi-Fi network. When the cellular network utilization is greater than certain threshold and if there is capacity available in the Wi-Fi network, then the present invention classifies the subscribers based on subscriber and network parameters and offloads them to the Wi-Fi network using adaptive dichotomic methodology. The proposed invention also analyzes any external interrupts with the pre-determined trigger rules and accords them highest priority for offload.

Disclosed are methods and systems for handling social media inputs in an existing multi-channel converged CSTA based infrastructure. The methods and systems may be characterized by determination of priority and potential churn index of the inputs received from sentiment analysis module based on predetermined parameters. The inputs are translated into qualifier by using predetermined combinations of severity index and anticipated churn index, which are then adapted into the CSTA specifications. Thereafter, the method and system includes determination of routing of the adapted posts for further treatment using inbound mechanism or outbound mechanism. Specifically, the routing of the inbound post is carried out leveraging the one number service of the CSTA based infrastructure.
