LED PEDD Discharge Photometry: Effects of Software Driven Measurements for Sensing Applications.

ABSTRACT: This work explores the effects of embedded software-driven measurements on a sensory target when using a LED as a photodetector. Water turbidity is used as the sensory target in this study to explore these effects using a practical and important water quality parameter. Impacts on turbidity measurements are examined by adopting the Paired Emitter Detector Diode (PEDD) capacitive discharge technique and comparing common embedded software/firmware implementations. The findings show that the chosen software method can (a) affect the detection performance by up to 67%, (b) result in a variable sampling frequency/period, and (c) lead to an disagreement of the photo capacitance by up to 23%. Optimized code is offered to correct for these issues and its effectiveness is shown through comparative analyses, with the disagreement reduced significantly from 23% to 0.18%. Overall, this work demonstrates that the embedded software is a key and critical factor for PEDD capacitive discharge measurements and must be considered carefully for future measurements in sensor related studies.

Project description:For more than thirty years, it has been claimed that a way to improve software developers' productivity and software quality is to focus on people and to provide incentives to make developers satisfied and happy. This claim has rarely been verified in software engineering research, which faces an additional challenge in comparison to more traditional engineering fields: software development is an intellectual activity and is dominated by often-neglected human factors (called human aspects in software engineering research). Among the many skills required for software development, developers must possess high analytical problem-solving skills and creativity for the software construction process. According to psychology research, affective states-emotions and moods-deeply influence the cognitive processing abilities and performance of workers, including creativity and analytical problem solving. Nonetheless, little research has investigated the correlation between the affective states, creativity, and analytical problem-solving performance of programmers. This article echoes the call to employ psychological measurements in software engineering research. We report a study with 42 participants to investigate the relationship between the affective states, creativity, and analytical problem-solving skills of software developers. The results offer support for the claim that happy developers are indeed better problem solvers in terms of their analytical abilities. The following contributions are made by this study: (1) providing a better understanding of the impact of affective states on the creativity and analytical problem-solving capacities of developers, (2) introducing and validating psychological measurements, theories, and concepts of affective states, creativity, and analytical-problem-solving skills in empirical software engineering, and (3) raising the need for studying the human factors of software engineering by employing a multidisciplinary viewpoint.

Project description:BackgroundEarly morning patient discharge from the hospital is increasingly being recognized as a key dimension of quality of care. At our institution, there is a significantly lower early discharge rate on the teaching hospitalist teams in comparison with the non-teaching teams.ObjectiveTo implement a resident-driven intervention in the teaching medical services to increase overall discharge order rate before 11 am (DOB-11) and assess the effect of this intervention on hospital length of stay (LOS), 30-day readmission rates (RR), and resident perception.DesignInterrupted time series as well as controlled before-after designs.ParticipantsAll inpatients discharged from general medicine units.InterventionsWe implemented an educational didactic in conjunction with resident-attending daily walk rounds followed by resident-led multidisciplinary discharge huddles to identify next-day discharges.Main measuresThe primary outcome was DOB-11 rates 18 months pre- and 12 months post-intervention.Secondary outcomesLOS and RR. Additionally, we assessed residents' perception of the early discharge protocol.Key resultsThe DOB-11 rate increased from 12 to 29% (p < 0.001), LOS increased by 1.47 days (P < 0.001), and RR increased by 0.32% (P = 0.84), respectively, on the teaching teams. Compared with the non-teaching (control) teams, the teaching teams registered a greater increase in DOB-11 rate (by 17%, p < 0.001; ratio of adjusted ORs 2.16; 95% CI, 1.65, 2.85; p value < 0.001), small increase in LOS (by 0.74 day, p = 0.39; ratio of adjusted post-/pre-intervention ratio [teaching] and post-/pre- intervention ratio [non-teaching] = 1.05, 95% CI, 0.97, 1.14, p = 0.23), and relative increase in RR (by 3.98%, p = 0.07, and ratio of ORs = 1.35, 95% CI, 1.03, 1.8), p = 0.03). Approximately 55% (16/29) of the residents agreed that the early discharge initiative helped in understanding the importance of prioritizing patients for early discharge. Additionally, 55% (20/36) of the residents "agreed" that the early discharge initiative compromised their learning during teaching rounds.ConclusionOur study demonstrates that DOB-11 is an achievable goal, not only for non-teaching teams but also for resident-run teaching teams.

Project description:ImportanceFamilies often struggle after discharge of a child from the hospital. Postdischarge challenges can lead to increased use of urgent health care services.ObjectiveTo determine whether a single nurse-led telephone call after pediatric discharge decreased the 30-day reutilization rate for urgent care services and enhanced overall transition success.Design, setting, and participantsThis Hospital-to-Home Outcomes (H2O) randomized clinical trial included 966 children and adolescents younger than 18 years (hereinafter referred to as children) admitted to general medicine services at a free-standing tertiary care children's hospital from May 11 through October 31, 2016. Data were analyzed as intention to treat and per protocol.InterventionsA postdischarge telephone call within 4 days of discharge compared with standard discharge.Main outcomes and measuresThe primary outcome was the 30-day reutilization rate for urgent health care services (ie, unplanned readmission, emergency department visit, or urgent care visit). Secondary outcomes included additional utilization measures, as well as parent coping, return to normalcy, and understanding of clinical warning signs measured at 14 days.ResultsA total of 966 children were enrolled and randomized (52.3% boys; median age [interquartile range], 2.4 years [0.5-7.8 years]). Of 483 children randomized to the intervention, the nurse telephone call was completed for 442 (91.5%). Children in the intervention and control arms had similar reutilization rates for 30-day urgent health care services (intervention group, 77 [15.9%]; control group, 63 [13.1%]; P = .21). Parents of children in the intervention group recalled more clinical warning signs at 14 days (mean, 1.8 [95% CI, 1.7-2.0] in the intervention group; 1.5 [95% CI, 1.4-1.6] in the control group; ratio of intervention to control, 1.2 [95% CI, 1.1-1.3]).Conclusions and relevanceAlthough postdischarge nurse contact did not decrease the reutilization rate of postdischarge urgent health care services, this method shows promise to bolster postdischarge education.Trial registrationClinicalTrials.gov Identifier: NCT02081846.

Project description:In today's digital world, app stores have become an essential part of software distribution, providing customers with a wide range of applications and opportunities for software developers to showcase their work. This study elaborates on the importance of end-user feedback for software evolution. However, in the literature, more emphasis has been given to high-rating & popular software apps while ignoring comparatively low-rating apps. Therefore, the proposed approach focuses on end-user reviews collected from 64 low-rated apps representing 14 categories in the Amazon App Store. We critically analyze feedback from low-rating apps and developed a grounded theory to identify various concepts important for software evolution and improving its quality including user interface (UI) and user experience (UX), functionality and features, compatibility and device-specific, performance and stability, customer support and responsiveness and security and privacy issues. Then, using a grounded theory and content analysis approach, a novel research dataset is curated to evaluate the performance of baseline machine learning (ML), and state-of-the-art deep learning (DL) algorithms in automatically classifying end-user feedback into frequently occurring issues. Various natural language processing and feature engineering techniques are utilized for improving and optimizing the performance of ML and DL classifiers. Also, an experimental study comparing various ML and DL algorithms, including multinomial naive Bayes (MNB), logistic regression (LR), random forest (RF), multi-layer perception (MLP), k-nearest neighbors (KNN), AdaBoost, Voting, convolutional neural network (CNN), long short-term memory (LSTM), bidirectional long short term memory (BiLSTM), gated recurrent unit (GRU), bidirectional gated recurrent unit (BiGRU), and recurrent neural network (RNN) classifiers, achieved satisfactory results in classifying end-user feedback to commonly occurring issues. Whereas, MLP, RF, BiGRU, GRU, CNN, LSTM, and Classifiers achieved average accuracies of 94%, 94%, 92%, 91%, 90%, 89%, and 89%, respectively. We employed the SHAP approach to identify the critical features associated with each issue type to enhance the explainability of the classifiers. This research sheds light on areas needing improvement in low-rated apps and opens up new avenues for developers to improve software quality based on user feedback.
