In renewable power generation doubly fed induction generators (DFIG) are used, in which the stator of the generator is directly connected to mains, while the converter for the rotor is rated only for slip power. Due to the interaction of rotor and stator windings in a DFIG, the high-frequency harmonics caused by the pulsed output of rotor power converters are transmitted into the stator current...

Current tools do not provide adequate support to users for handling reminders. The main reason for this is the lack of use of rich context that specifies when a reminder should be presented to its recipient. We describe CybreMinder, a prototype context-aware tool that supports users in sending and receiving reminders that can be associated to richly described situations involving time, place an...

Tracking health related behaviors regularly helps in forming good health habits, which greatly improve our health status in the long run. Self-reporting is the most acceptable behavior tracking method, but it suffers from issues like recall bias and low consistency. We propose a novel platform to mitigate these issues: It can send smart reminders to the user’s smartphone soon after completion o...

Objectives: Since forgetfulness is the major cause of missed appointments, reminder systems can be used prior to appointments. The present study aimed to evaluate the efficacy of different reminders [e-mails, social networks, telephone, and short message service (SMS)] in order to reduce missed appointments by orthodontic patients. Methods: Of a total of 751 active orthodontic patients, 379 we...

BACKGROUND Telephone or text-message reminders have been shown to significantly reduce the rate of missed appointments in different medical settings. Since text-messaging is less resource-demanding, we tested the hypothesis that text-message reminders would be as effective as telephone reminders in an academic primary care clinic. METHODS A randomized controlled non-inferiority trial was cond...

BACKGROUND Cell phone text messaging, via the Short Messaging Service (SMS), offers the promise of a highly portable, well-accepted, and inexpensive modality for engaging youth and young adults in the management of their diabetes. This pilot and feasibility study compared two-way SMS cell phone messaging with e-mail reminders that were directed at encouraging blood glucose (BG) monitoring. ME...

Methods Using existing well-accepted evidence-based national clinical guidelines, a multidisciplinary team created 16 specific reminders within 4 clinical categories: (1) diabetes care (eye exams, HbA1C and cholesterol studies, nursing education visits); (2) therapeutic recommendations (ACE-inhibitor (ACEI) use in diabetic hypertensives; aspirin, beta-blocker, and statin use in patients with co...

OBJECTIVE Little evidence exists on effective interventions to integrate HIV-care guidelines into practices within developing countries. This study tested the hypothesis that clinical summaries with computer-generated reminders could improve clinicians' compliance with CD4 testing guidelines in the resource-limited setting of sub-Saharan Africa. DESIGN A prospective comparative study of two r...

People often fail to follow through on good intentions. While limited self-control is frequently the culprit, another cause is simply forgetting to enact intentions when opportunities arise. We introduce a novel, potent approach to facilitating follow-through: the reminders-through-association approach. This approach involves associating intentions (e.g., to mail a letter on your desk tomorrow)...
