  • Publication number: 20170293597
    Abstract: This invention relates to methods and systems for message analysis and classification. It is particularly applicable to analysis and classification of very short messages such as “Tweets”. Embodiments of the invention provide methods for unbiased enriched representation for messages which can be used to transform very short messages into comparatively longer text. These methods can make use of word context information in addition to word information itself. This can provide text with enough information for analysis and classification without changing the information in the original message. Embodiments of the invention also provide a statistical learning mechanism which does not require pre-defined keywords, and can automatically detect inherent frequent words and word patterns. These methods can provide satisfactory classification accuracy even for very short messages.

  • Publication number: 20170214070
    Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.

  • Publication number: 20170206026
    Abstract: Aspects extend to methods, systems, and computer program products for predicting solid state drive reliability. Aspects of the invention can be used to predict and/or to configure a data center to minimize one or more of: SSD capacity degradation (how much storage an SSD has left), SSD performance degradation (reduced read/write latency/throughput), and SSD failure. Models and data center considerations can be based on device level SSD related operations, such as, for example, read, write, erase. Operations decisions can be made for a data center based on SSD specific features, such as, for example, remaining capacity, write amplification factor, etc. Dependence and/or causality of various different data center factors can be leveraged. The impact of the various data center factors on different SSD failure modes and capacity/performance degradation can be quantified to drive SSD design, SSD provisioning, and SSD operations.
