Research ArticleOpen accessEvery word in the titleAn Automated Time-Shift Alignment Algorithm Based on Discrete to Continuous ApproachWajih Rhalem, Mourad Raji, Ahmed Hammouch, Jamal El MhamdiDealing with the variation in retention time and time series is one of the most popular challenges in the field of analysing data obtained from biological experiments. In most cases, this problem can lead to invalid conclusions. This work aims to propose a new method to cope with this problem by using the principle of the transition from discrete to … …Journal of Computer Science, Vol. 15, Issue 4 · 15 Apr 2019 · 7,766 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBit Error Rate Analysis of RS (7, 3) Coded Frequency Shift Keying Using SimulinkT.A. Shanmugasundaram, V. VijayabaskarBit Error Rate is an essential parameter to quantize the effectiveness of transceiver circuits used in low power, low duty cycle sensor nodes. BER can figure out their performance in terms of number of retransmissions, which keeps the node to consume its battery power undesirably rather than conserving it. Forward Error Correction schemes ensure the transceiver circuit to effectively perform … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 25 Mar 2015 · 7,047 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAdaptive Cross-Validation Under Concept Drift for Time Series ForecastingKunjira Kingphai, Prapakorn Kanjina, Kamol Sanittham, Wacharong WongsanurakTime-series forecasting often involves non-stationary data, making i.i.d. validation unreliable and fixed-window protocols vulnerable to leakage and biased error estimates. We propose Adaptive Time-Series Cross-Validation (ATSCV), a drift-aware evaluation framework that uses statistical change-point detection to partition each series into contiguous, approximately stationary regimes, followed by forward-chaining folds that respect those boundaries. By aligning train–validation splits with distributional changes (with … …Journal of Computer Science, Vol. 22, Issue 7 · 7 Jul 2026 · 1,488 accessesView PDFCite

Research ArticleOpen accessIn the keywordsAn Investigation of Work-Related Fatigue Levels and Related Factors among Emergency Nurses: A Primary Quantitative StudyKhaldoun Ismail, Mahmoud Al-Masaeed, Rawan Alsababha et al.One of the most frequent phenomena among shift workers, particularly nurses, is work-related fatigue. There is a necessary demand for research in the area concerning the relationship between socio-demographic factors, occupational variables and work-related fatigue among Arabic, including Jordanian nurses, given the lack of knowledge. This study targets evaluating the magnitude of the relationship between socio-demographic and occupational factors and … …International Journal of Research in Nursing, Vol. 12, Issue 1 · 5 Mar 2021 · 7,005 accessesView PDFCite

Research ArticleOpen accessIn the keywordsLow Transition Test Pattern Generator Architecture for Built-in-Self-TestP. Sakthivel, A. NirmalKumar, T. MayilsamyProblem statement: In Built-In Self-Test (BIST), test patterns are generated and applied to the Circuit-Under-Test (CUT) by on-chip hardware; minimizing hardware overhead is a major concern of BIST implementation. In pseudorandom BIST architectures, the test patterns are generated in random nature by linear feedback shift registers. This normally requires more number of test patterns for testing the architectures which need … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 21 Jul 2012 · 7,357 accessesView PDFCite
