Enhancing Software Development Process Quality based on Metrics Correlation and Suggestion

To improve software quality, it is necessary to introduce new metrics with the required detail and increased expressive power, in order to provide valuable information to the different actors of software development. In this paper we present two approaches based on metrics that contribute to improve software quality development. Both approaches are complementary and are focused on the combination, reuse and correlation of metrics. They suggest to the user indications of how to reuse metrics and provide recommendations after the application of metrics correlation. They have been applied to selected metrics on software maintainability, safety, security etc. The approaches have been implemented in two tools, Metrics Suggester and MINT. Both approaches and tools are part of the ITEA3 MEASURE project and they have been integrated into the project platform. To illustrate its application we have created different scenarios on which both approaches are applied. Results show that both approaches are complementary and can be used to improve the software
A Stochastic Analytical Modeling Framework on ISP–P2P Collaborations in Multidomain Environments

Cooperation between peer-to-peer (P2P) overlays and underlying networks has been proposed as an effective approach to improve the efficiency of both the applications and the underlying networks. However, fundamental characteristics with respect to Internet service providers (ISP) business relationships and inter-ISP routing information are not sufficiently investigated in the context of collaborative ISP–P2P paradigms in multidomain environments. In this paper, we focus on such issues and develop an analytical modeling framework for analyzing optimized interdomain peer selection schemes concerning ISP policies, with the main purpose of mitigating cross-ISP traffic and enhancing service quality of end users. In addition, we introduce an advanced hybrid scheme for peer selections based on the proposed analytical theory framework, in accordance with practical network scenarios, wherein cooperative and noncooperative behaviors coexisting. Numerical results show that the proposed scheme incorporating ISP policies is able to achieve desirable network efficiency as well as great service quality for P2P users. Our analytical modeling framework can be used as a guide for analyzing and evaluating future network-aware P2P peer selection paradigms in general multidomain scenarios.

Long-Duration Surface Anchoring With a Hybrid Electrostatic and Gecko-Inspired Adhesive

Many scenarios require access to locations that are difficult to reach; however, mobile and untethered robots for these applications operate on a limited reserve of energy. Researchers often design robots specifically to be able to wait for periods of time in low-power states, conserving energy, and protecting hardware during periods of inactivity. In this letter, we introduce a temporary anchor using a low-power hybrid electrostatic/gecko-inspired adhesive for robots such as quadrotors and wall-climbing systems to allow access to remote areas while providing the ability to safely hold a position for an extended duration. This letter presents a self-contained electrostatic and gecko-inspired adhesive anchor mechanism, which is particularly well suited for long-duration payload placement. With structural layers comprised of a rigid plate and a soft foam, this anchor distributes normal stress across the pad while maintaining the compliance required for effective use of the adhesives. This new approach to loading the hybrid adhesive increases the distance off-the-wall that a payload can be supported, even on rough surfaces. We model the capacity of the device and demonstrate carrying an 11.9 N load applied 12 mm off of a rough drywall surface with an adhesive area of 32 cm$^{-2}$. We also offer two innovations that extend the mission-duration of an electrostatic adhesive anchor. We show that polyimide, a common dielectric layer in flex circuits, is prone to failing over a period of hours while both polyethylene-terephthalate and polyethylene-napthalate films demonstrate long-term stability under the applied electrical field. Furthermore, to reduce the power consumption of the adhesive, we introduce the concept of power-cycling, and reduce power consumption by an order of magnitude while still maintaining over 85 percent adhesion strength.This temporary anchor can be scaled in size to suit a given application, with virtually no difference in power draw or required electronics.We model the payload capacity of the anchor, and demonstrate performance on a variety of surfaces.
Recent insights into the role of ChREBP in intestinal fructose absorption and metabolism

Fructose in the form of sucrose and high fructose corn syrup is absorbed by the intestinal transporter and mainly metabolized in the small intestine. However, excess intake of fructose overwhelms the absorptive capacity of the small intestine, leading to fructose malabsorption. Carbohydrate response element-binding protein (ChREBP) is a basic helix-loop-helix leucine zipper transcription factor that plays a key role in glycolytic and lipogenic gene expression in response to carbohydrate consumption. While ChREBP was initially identified as a glucose-responsive factor in the liver, recent evidence suggests that ChREBP is essential for fructoseinduced lipogenesis and gluconeogenesis in the small intestine as well as in the liver. We recently identified that the loss of ChREBP leads to fructose intolerance via insufficient induction of genes involved in fructose transport and metabolism in the intestine. As fructose consumption is increasing and closely associated with metabolic and gastrointestinal diseases, a comprehensive understanding of cellular fructose sensing and metabolism via ChREBP may uncover new therapeutic opportunities. In this mini review, we briefly summarize recent progress in intestinal fructose metabolism, regulation and function of ChREBP by fructose, and delineate the potential mechanisms by which excessive fructose consumption may lead to irritable bowel syndrome.

While confining the jounce for a gentle motion, the proposed scheme includes a time-optimal control law so as to achieve a fast response. The proposed scheme has been practically realized and experimentally compared with other conventional schemes.
Automatic Attendance Control System based on BLE Technology

As an emerging low power wireless technology, Bluetooth Low Energy lately has become an essential part of the Internet of Things world. Its pervasiveness has given the possibility for many different, otherwise manually driven, concepts to work in a different, enhanced, and more automated fashion. In this paper, we present an automatic attendance control system based on the interaction between a modified BLE iBeacon mechanism and users’ smart devices. As such, the system can recognize users according to predefined profiles and eventually broadcast valuable information that corresponds to recognized profiles. The proof of concept shows that this is a promising approach regarding automating specific tasks, recognizing users and interacting with them less complexly.
Analyzing Collaboration in the Gamification Process of Childprogramming

According to Jeannette Wing computational thinking involves problem solving, system design and understanding of human behavior, making use of the fundamental concepts of informatics, thus, it means that boys and girls acquire skills to solve problems in different contexts through informatics and software programming in different devices. For the purpose of supporting the initiatives to strengthen the development of computational thinking, the Software engineering research and development group (IDIS) of the University of Cauca, in 2012 formalized the Childprogramming model to support the development of software oriented to children, based on strategies of collaborative learning, agile software development, and ludic learning. Since then, this model has been improved, such as, the Childprogramming-G model that looks for the improvement of the ludic learning, offering gamification strategies for the software development process carried out by children. This article presents an exploratory case study where the ChildProgramming-G version was applied, taking some dynamics and game mechanics combined with the previous sensitization of the importance of collaborative work in children's work teams. From this case study it was possible to obtain more information about the collaborative processes involved in the teachinglearning process of the software development carried out by children.
Automatic Planning of Manufacturing Processes using Spatial Construction Plan Analysis and Extensible Heuristic Search

When automating small-batch manufacturing processes, the time spent for process planning and robot programming becomes more important. This paper proposes an automated process including construction plan analysis, process planning and execution to reduce the amount of manual work required. The process starts by analyzing the structure of the desired product and deriving required process step results, then uses heuristic search to find possible production steps and task assignments, and concludes by simulating or executing the resulting production plan. The approach is evaluated on a case study with a simulated robot automatically building different LEGO R © DUPLO R ©structures starting from a 3D model defining the desired product.
An Intelligent-Based Fault-Tolerant System for Solar-Fed Cascaded Multilevel Inverters

This paper presents an intelligent-based fault-tolerant system for a solar photovoltaic (PV) inverter. Artificial neural network based controller is used to monitor, detect, and diagnose the faults in solar PV panels, battery, semiconductor switches, and inverters. The cascaded multilevel inverter is connected across the combination of solar PV panel and battery for dc–ac conversion. The major advantage of the proposed topology is that it can deliver power from source to the load even under fault and partial shaded conditions. The paper also reviews on various faults in the solar PV energy conversion process and provides suitable solutions for each circumstance. Simulations are undertaken in MATLAB 2016a/Simulink and experimental investigation is carried out for a 3 kWp solar PV system. The results have proven that the system is capable to deliver power in spite of faulty environments. The comparison and discussion of the results were made to show the effectiveness of the proposed system.

Condition Monitoring of Electrolytic Capacitors via ESR Estimation with Recursive Least Squares and Sliding Mode Techniques

A new on-line electrolytic capacitor condition monitoring approach based on sliding mode concepts and the recursive least squares (RLS) with constant forgetting factor algorithm is proposed in this paper. This scheme involves robust exact differentiation which outperforms the classical differentiator based on linear approximations, when the system is affected by noise. The condition monitoring approach proposed in this paper allows for on-line estimation of the ESR which is considered to be one of the best indicators of capacitor degradation. Computer simulation results, considering a DC-DC buck converter, provide evidence of the effectiveness of the capacitor condition monitoring scheme proposed in this paper.
LiDAR Intensity Calibration for Road Marking Extraction

The rising demand for precise three-dimensional (3D) maps is a result of the growth of autonomous vehicles into a major focus. These precise 3D maps are often created using Mobile Mapping System (MMS) instruments equipped with various sensors. Among these sensors, Light Detection and Ranging (LiDAR) is the most widely adopted sensor for the generation of 3D maps. This paper describes the intensity calibration process for 3D LiDAR sensors installed on MMS. A typical LiDAR sensor measures the distance to an object in addition to intensity, which is the magnitude of the reflection from the surface of an object. Physically, the value of intensity depends on three factors: reflectance, the distance from the surface, and the angle of incidence. Therefore, the intensity values of road markings with the same reflectance may result in different intensity values depending on distance and angle of incidence. The method proposed in this paper aims to correct the measured intensity value of objects to ensure the measurements of the same object reports the same intensity value. To solve this issue, the intensity characteristic of each sensor with regards to a reference surface was exploited and the reflectance of the surface was estimated. The calibration result was validated via road marking extraction with Otsu threshold method.
Optimization of a DC Motor Drive Using a Firefly Algorithm

Optimization algorithms belonging to the group of artificial intelligence algorithms are becoming far more commonly used in practical applications. This article presents examples of two methods for optimization of an electrical drive controller's parameters using several quality criteria and constrained maximum values of signals in the controlled object. The two methods presented are the genetic algorithm and the firefly algorithm. In addition, solutions to the problem were sought using a modified firefly method and the traditional firefly method with operating parameters optimized for this particular problem. An effect of the firefly algorithm parameters on the speed of the solution search was observed.
Influence of Facial Expressions on the Human Head Movements

This paper addresses the problem of simulating human head motions for avatars. The presented approach includes the data extracted in the video sequences analysis process, stochastic simulations and the three-dimensional geometrical head model. The main goal of the research concerns on expressing emotion through head movement. Therefore we have described the head movements when a person expresses facial expressions. The aspect of head movement is essential in avatar/robot motion, because it provides additional information about the emotional state or it will fill a gap in idle animation where the virtual person or robot is waiting for action. Therefore the technique can increase the level of realism while performing human-machine interactions.
Experimental Measurements of Communication Technologies for Mesh Distribution Networks of Low Voltage

For future smart grids, meshed or interconnected grids of low voltage should be important. Low voltage grids are mostly structured as an open ring or radial power distribution network. Meshed or interconnected grid topologies bring higher reliability, higher voltage stability and lower losses, but these mesh grids are more expensive than traditional topologies and their operation is much more complicated. The first part of the article provides a survey of possible communication technologies for mesh power distribution networks and particular Smart Grid applications. The second part of the article focuses on on-field experimental measurements of particular communication technologies suitable for deployment in mesh power distribution networks.
Harmonic Power Sharing With Voltage Distortion Compensation of Droop Controlled Islanded Microgrids

Harmonics are found to have deleterious effects on power system equipment including transformers, capacitor banks, rotating machines, etc. However, the distributed generation interfacing converters (DICs) are able to improve power quality and system efficiency in case of adding a flexible control strategy. This paper describes the voltage distortion generated by nonlinear loads and proposes a new harmonic droop control to reduce the voltage harmonic distortion at the point of common coupling (PCC) and to share the harmonic power between parallel islanded inverters controlled by classical frequency droop method. The main objective it to effectively compensate the harmonic currents drawn by each DIC to supply the nonlinear loads in parallel with voltage harmonic damping at PCC. The operation principle of the proposed harmonic droop is explained in details. Modeling and stability analysis are developed in order to define the control parameters suitable for proper operation. Simulation and experimental results are presented to show the competence of the proposed algorithm in achieving harmonic power sharing and in improving the voltage harmonic distortion at the PCC.
Interprofessional education and practice guide No. 9: Sustaining interprofessional simulation using change management principles

ABSTRACT Collaboration between teams is an essential component of patient safety in the complex ever-changing environment of healthcare. Collaborative practice requires training, which needs to start prior to registration for it to be established in the clinical workforce by graduation. Despite the perceived value and motivation of course coordinators, interprofessional training programs often struggle to sustain, due to various reasons related to logistics of timetabling, staff availability and/or absence of institutional support. We present a guide, outlining the lessons learned from implementing a sustainable change from our 6-year experience of the Women’s Health Interprofessional Learning through Simulation (WHIPLS) program. The WHIPLS program was initially piloted to teach clinical skills in an interprofessional environment for pre-registration medical and midwifery students and has become a core component of the clinical curriculum. We describe the steps that were required to attain this outcome using the Kotter’s 8-step plan for management change. The key lessons learned were identifying overlaps in course curriculum, planning for leadership and implementation, creating institutional “buy-in”, aligning with national goals, focusing on the learner, translating into routine clinical practice, keeping the program simple, accepting innovation and considering a strategic evaluation.
3D Face Tracking Using Stereo Camera

The content of this article explores the use of 3D face tracking systems by implementing of active stereo vision cameras to ascertain the position of a person's face. The various experiments conducted in-depth have produced both promising and satisfying results for images that have enabled examiners to determine the disparity between images. The paper also explores some of the various challenges researchers are facing with the implementation of algorithms to construct cloud-points in from stereo-based images. The reviewed recommendations suggest on better software components that would avail final 3D computational images or reconstructions that can easily be matched to the original. The tracking system modules address the challenges of the practical application of face tracking including pose illumination and occlusion. The content of the paper evaluates the putting into practice of multi-view or multiple stereo cameras enhance the field of view to improve the performance of a 3D tracking system. Face tracking using functional multi-view stereo camera systems can significantly solve the correspondence problem and the issue of comparing scenes or image points given that extra views reduced ambiguity in matching.
Loss Evaluation for the Hybrid Cascaded MMC Under Different Voltage-Regulation Methods

This paper presents a quantitative analysis of the losses of the hybrid cascaded modular multilevel converter (HC-MMC). Regulation of full-bridge (FB) submodule-capacitor voltages in an HC-MMC requires dedicated strategies that affect the voltage harmonics generated by the converter's main power stage and hence its switching patterns and losses. This paper uses an electromagnetic transient simulator (PSCAD/EMTDC) to estimate the semiconductor losses using the switches’ turn-on and turn-off characteristics. The paper examines the losses of a 45-MW HC-MMC for two recently introduced voltage-regulation methods based upon the modified sinusoidal pulse width modulation (PWM) and an existing method based upon the trapezoidal PWM. Losses of a conventional FB-MMC that offers dc-fault blocking capability are also investigated and compared with those of HC-MMC. The loss comparison results indicate that: first, the two voltage-regulation methods for HC-MMC based upon the modified sinusoidal PWM result in markedly lower semiconductor losses than the trapezoidal PWM method; second, compared with the original HC-MMC, a mixed submodule HC-MMC may lower the semiconductor losses at certain operating points with proper addition of mixed submodules; and finally, HC-MMC may have up to 9.0% lower semiconductor losses (relative) than the conventional FB-MMC.
