Stream-switching techniques are applied in a content delivery system. A merge frame is generated as a function of bit-rates, distortion, and a piecewise constant operator. Parameters of the piecewise constant operator are selected to optimize the merge frame. Data streams are switched based on bandwidth requirements, switch requests, and throughput of a network. Images are reconstructed based on the merge frames and prediction frames. Reconstructed images are identically reconstructed for any prediction frame based on the merge frame.

An information processing unit and information processing method capable of performing a ground-state search of an Ising model having coefficients of arbitrary values regardless of restrictions on hardware or software is suggested. When a ground state of an original problem, which is an Ising model, or an approximate solution of that ground state is calculated as a solution of the original problem, one or more sub-problems which are Ising models are generated from the original problem and the information processing unit searches the ground state of each generated sub-problem and generates a solution of the original problem based on a solution of each sub-problem obtained from the search; and when types of coefficient values of an Ising model whose ground state can be searched are limited, sub-problems which are Ising models composed of the types of limited values of coefficients are generated.

Purpose: For most of the 20th century, students with visual impairments were placed in separate schools from their peers. With major advances in public policy, it is now more common that all students (regardless of such disabilities) be integrated within schools and in classrooms. Recent research demonstrates a lack of products to support the visually impaired in STEM (science, technology, engineering, and mathematics) classrooms, as schools today often rely on large print or curricular materials that cannot wholly convey information to students. This project will develop a platform to enrich STEM learning among students with (or without) visual impairments. Project Activities: After mock-ups are completed, prototypes of the multi-media learning applications (apps) will be developed. A user-interface will be designed to house the apps and the materials needed to implement the intervention. Next, programming code will be authored to integrate a haptic controller device with the platform to enable tactile sensory learning opportunities. To assess implementation feasibility, the usability of the technology, and to gather data on the promise of the product to support learning, the pilot study will follow 10 classrooms over two months. The classrooms will include a mixture of students with and without visual impairments. Half of the classrooms will use the product to supplement their normal science curriculum whereas the other half will serve as a business-as-usual comparison group. Research questions will address the ease of integration of the product within classrooms, whether visually impaired students have greater access to science data than typical practices, and whether students learn more from using the platform compared to those not using the product. Pre and post measures will address STEM topics.

A time-series waveform of tire vibration detected by an acceleration sensor is windowed by a windowing means, time-series waveforms of the tire vibration are extracted for respective time windows, and feature vectors of the respective time windows are calculated. Then kernel functions are calculated from the feature vectors of the respective time windows and road surface feature vectors, which are the feature vectors for the respective time windows calculated from the time-series waveform of the tire vibration obtained for distinctive road surface conditions calculated in advance. And the road surface condition is determined by comparing values of discriminant functions using the kernel functions. As a result, the road surface condition can be determined from the time-series waveform of the tire vibration without detecting peak positions or measuring the wheel speed. Moreover, robustness against changes in tire size can be added to the determination of the road surface condition.
