Gene-set enrichment analyses (GEA or GSEA) are commonly used for biological characterization of an experimental gene-set. This is done by finding known functional categories, such as pathways or Gene Ontology terms, that are over-represented in the experimental set; the assessment is based on an overlap statistic. Rich biological information in terms of(More)
Due to limits on the availability of the energy source in many mobile user platforms (ranging from handheld devices to portable electronics to deeply embedded devices) and concerns about how much heat can effectively be removed from chips, minimizing the power consumption has become a primary driver for system-on-chip designers. Because of their superb(More)
BACKGROUND Principal component analysis (PCA) has gained popularity as a method for the analysis of high-dimensional genomic data. However, it is often difficult to interpret the results because the principal components are linear combinations of all variables, and the coefficients (loadings) are typically nonzero. These nonzero values also reflect poor(More)
Modern smartphones consume significant power and can hardly provide a full day's use between charging operations even with a 2000 mAh battery. This is in spite of many power management techniques being employed in the smartphones. This paper starts from the observation that modern smartphones waste a significant amount of the battery's stored energy during(More)
Emerging mobile systems integrate a lot of functionality into a small form factor with a small energy source in the form of rechargeable battery. This situation necessitates accurate estimation of the remaining energy in the battery such that user applications can be judicious on how they consume this scarce and precious resource. This paper thus focuses on(More)
Photovoltaic (PV) cells are promising endurable renewable power sources that do not include mechanical components, which are subject to wear and tear. However, actual development of a solar-powered system requires elaborated design processes to find the best setup including location determination and development of a maximum power point tracking method,(More)
—Smartphones consume a significant amount of power. Indeed they can hardly provide a full day of use between charging operations even with a 2000 mAh battery. While power minimization and dynamic power management (DPM) techniques have been heavily explored to improve the power efficiency of modules (processors, memory, display, GPS, etc.) inside a(More)
—The emerging trend toward utilizing chip multi-core processors (CMPs) that support dynamic voltage and frequency scaling (DVFS) is driven by user requirements for high performance and low power. To overcome limitations of the conventional chip-wide DVFS and achieve the maximum possible energy saving, per-core DVFS is being enabled in the recent CMP(More)
