Aspects of the disclosure provide a system for disease detection. The system includes an interface circuit, a memory circuit, and a disease detection circuitry. The interface circuit is configured to receive data events associated with a patient sampled at different time for disease detection. The memory circuit is configured to store configurations of a model for detecting a disease. The model is generated using machine learning technique based on time- series data events from patients that are diagnosed with/without the disease. The disease detection circuitry is configured to apply the model to the data events to detect an occurrence of the disease.


The methods and systems described herein centralize simulation resources and effectively delivering training and simulation services to a broad set of distributed users at both the enterprise and operational levels. The cloud-based delivery of simulation applications described herein enables on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. In exemplary systems, users may provision computing capabilities, such as server time and network storage, as needed, automatically without requiring human interaction.


A Volatile Organic Compound (VOC) mitigation system employs a combination of technologies coupling VOC laden exhaust with a reciprocating engine and generator system (Combined Heat & Power (CHP) System) with heat recovery to destroy the VOC emissions and generate electric power and useful thermal energy.

An adaptive phased-array processing solution, referred to as the Wideband Beamformer System (WBS), demonstrates an improvement in the range and quality of air link surveillance downlink wireless cell radio signals. The WBS applies wideband frequency-domain adaptive beamforming to preprocess the dense RF signal environment, minimizing co-channel interference (CCI) from each signal, and then reconstructing a clean version of the signal for input to the existing surveillance receiver(s).

Systems and methods are described herein for a self-referencing interferometer. The interferometer can comprise an improved spatial phase shifter that reduces the number of components, size and complexity of the spatial phase shifter and maintains a common path for a combined reference beam and signal beam. The self-referencing interferometer further comprises a single mode fiber shunt for filtering the reference beam and further reducing the size of the interferometer. The angle of the reference beam can be tilted before being recombined with the single beam which further simplifies the spatial phase shifting component of the interferometer.


A processing platform integrates ETL (extract, transform, and load), real time stream processing, and big data data stores into a high performance analytic system that runs in a public or private cloud. The platform performs real time pre-storage enrichment of data records to form a single comprehensive record usable for analytics, searching and alerting. The platform further supports sharing of components and plug-ins and performs automatic scaling of resources based on real time resource monitoring and analysis.

Mixed-phase TiO_(2 )nanofibers prepared via a sol-gel technique followed by electrospinning and calcination are provided as photocatalysts. The calcination temperature is adjusted to control the rutile phase fraction in TiO_(2 )nanofibers relative to the anatase phase. Post-calcined TiO_(2 )nanofibers composed of 38 wt % rutile and 62 wt % anatase exhibited the highest initial rate constant of UV photocatalysis. This can be attributed to the combined influences of the fibers specific surface areas and their phase compositions.


A system and associated method for isolating intended radiation signals for determining target characteristics includes multiple detectors for detecting radiation signals having varying energies, delay modules for delaying the detected radiation signals and a discriminator associated with the multiple detectors for determining if detected radiation signals include unintended radiation signals, e.g., x-rays, and provided blanking signals to a switch in order to effectively remove the unintended radiation signals from the data that is presented to the processor for determining target characteristics.

The shortcoming of pure activated carbons is that chemicals with weak intermolecular forces typically have weak physical interactions with the carbon surface and therefore require chemical reactivity for removal. Thus, early gas masks were large, bulky, and burdensome to ensure proper protection for the user. Over the past century, the gas mask has changed substantially many times focused on the purported threat of the day. To properly afford broad spectrum protection, activated carbons must be impregnated with a variety of compounds capable of both acidic and basic chemistries. Due to the proximity of complementary functionalities within the pores of carbons, these chemical groups will inherently interact with one another over time, reducing the efficacy of the material. Instead, covalently anchoring functional groups to the substrate may be advantageous, a property that can be imparted through crystal design of materials, such as metal-organic frameworks (MOF).
