Assignee:

Michael Freedman & Associates, Inc. - Edison NJ

International Classification:

E04B 1/82

US Classification:

181290, 181284

Abstract:

An acoustical vinyl tile having an integral acoustical layer is disclosed. The vinyl tile includes a vinyl portion, an acoustical portion, and an adhesive layer for fixing the vinyl portion to the acoustical portion. The acoustical portion comprises a crumb rubber component and a polyurethane foam component. The acoustical portion can include 10-40% crumb rubber and 60-90% polyurethane foam. The resulting vinyl tile meets ASTM E 2179 IIC sound requirements. A method of making a vinyl tile meeting the ASTM sound requirements is also disclosed. The method includes providing a vinyl slab portion, providing an acoustical slab portion comprising crumb rubber, polyurethane foam and a resin binder; and bonding the vinyl slab portion to the acoustical portion. Other embodiments are described and claimed.

Abstract:

An adaptive learning system and method provides for automatically generating question types to a user for word comprehension and selecting multiple choice answers for display. Questions are developed for the user by obtaining online content and indexing the content into individual sentences and questions. The system provides questions in a series of rounds to the user and then adaptively tracks the progress of the user based on the categorization of each question.

Abstract:

Materialized views are maintained for time-series databases, to enable faster analytics over large data sets and to downsample data for storage savings. These materialized views are the result of computations on existing tables, such as aggregation, approximation, sampling, filtering, statistical estimates, and more. A materialized view is created on a base table, and continuously maintained, such that as changes are made to the base table, the materialized view is correspondingly updated. The database system records metadata identifying regions of the base table that have already been materialized. Subsequently, these invalidated regions are rematerialized. Queries ensure up-to-date results by combining data from the materialized view with results calculated at query time on the base table. Invalidation records and completion thresholds are used to determine which results should use records from the materialized table and which should be computed from records from the base table.

Abstract:

Materialized views are maintained for time-series databases, to enable faster analytics over large data sets and to downsample data for storage savings. These materialized views are the result of computations on existing tables, such as aggregation, approximation, sampling, filtering, statistical estimates, and more. A materialized view is created on a base table, and continuously maintained, such that as changes are made to the base table, the materialized view is correspondingly updated, either synchronously or asynchronously. The database system records metadata identifying regions of the base table that have already been materialized. Subsequently, these invalidated regions are rematerialized. Queries ensure up-to-date results by combining data from the materialized view with results calculated at query time on the base table. Invalidation records and completion thresholds are used to determine which results should use records from the materialized table and which from records from the base table. Hierarchical materializations are also maintained.

Abstract:

Disclosed are solutions for improving Internet video streaming. A first number is determined based on one or more parameters, including network conditions. A second number is then determined corresponding to a number of video segments that is greater than or equal in size to a third number determined based on a bandwidth-delay product of the network to a remote machine. The second number of video segments is then requested in a pipelined fashion. Pipelined requests are stopped when a predetermined size of the video has been requested that is greater than or equal to the first number. Alternatively, a request is sent to the remote machine to send a portion of the video, where the size of the portion of the video is equal to the first number or equal to the size of video remaining if less than the first number. Combined with pipelining, the approach achieves near-optimal throughput and fast bitrate adaptation, regardless of control plane algorithm.

Abstract:

A database system stores data as hypertables that represent partitioned database tables. Each hypertable comprises chunks of data that may be distributed across multiple locations, each location comprising at least a storage device. The database system provides an interface that allows database queries seamlessly to hypertables as well as standard tables. The database system dynamically creates chunks as records are added to a hypertable. The database system defines a new partitioning strategy if the storage configuration of the database system is changed by adding new locations or removing existing locations. The records added to the hypertable before the storage configuration was changed continue to be stored as chunks distributed according to the previous partitioning policy.
