C10M 105/02

US Classification:

508110, 208 18

Abstract:

This invention relates to basestocks and base oils with improved low temperature properties and formulated lubricant compositions or functional fluids created by blending at least one such lube basestock with at least one component selected from dispersants, detergents, wear inhibitors, antioxidants, rust inhibitors, demulsifiers, extreme pressure agents, friction modifiers, multifunction additives, viscosity index improvers, pour point depressants, and foam inhibitors. In particular the invention relates to dewaxed lube basestocks having a Free Carbon Index of less than 4.3 and an Epsilon Carbon mole % of less than 14%. Formulated engine oils using such dewaxed basestocks exhibit improved low temperature properties as may be measured by the Mini Rotary Viscometer test.

International Classification:

B05D 5/12

US Classification:

427 79

Abstract:

Provided are processes for the manufacture of capacitors. It is found that by using a nickel foil as the substrate and one electrode of the capacitor and by controlling the oxygen partial pressure in the range of 10to 10atmospheres during the crystallization heat treatment of the barium titanate, the leakage current can be maintained at adequate values without a reoxygenation step.

Appl. No.:

13/280031

Inventors:

Riddhiman Ghosh - Sunnyvale CA, US
Lei Zhang - Chicago IL, US
Mohamed E. Dekhil - Santa Clara CA, US

International Classification:

G06F 17/27

US Classification:

704 9

Abstract:

There is provided a computer-implemented method of performing sentiment analysis. An exemplary method comprises performing a first sentiment analysis on microblogging data based on a method using an opinion lexicon. The method also includes training a classifier using training data from the first sentiment analysis. Additionally, the method includes identifying a new opinion term in the microblogging data by performing a statistical test. The new opinion terms are not in the opinion lexicon. The method also includes identifying new microblogging data based on the new opinion term. Further, the method includes performing a second sentiment analysis on the new microblogging data using the classifier.

US Classification:

704 9

Abstract:

There is provided a computer-implemented method of performing sentiment analysis. An exemplary method comprises identifying one or more sentences in a microblog. The microblog comprises an entity. The method further includes identifying one or more opinion words in the sentences based on an opinion lexicon. Additionally, the method includes determining, for each of the sentences, an opinion value for the entity.

International Classification:

G06K 9/00

G06T 7/20
G06N 3/04
G06K 9/62

Abstract:

A system for tracking a target object across a plurality of image frames. The system comprises a logic machine and a storage machine. The storage machine holds instructions executable by the logic machine to calculate a trajectory for the target object over one or more previous frames occurring before a target frame. Responsive to assessing no detection of the target object in the target frame, the instructions are executable to predict an estimated region for the target object based on the trajectory, predict an occlusion center based on a set of candidate occluding locations for a set of other objects within a threshold distance of the estimated region, each location of the set of candidate occluding locations overlapping with the estimated region, and automatically estimate a bounding box for the target object in the target frame based on the occlusion center.

G06T 3/00
G06T 3/40
G02B 27/01

Abstract:

Systems and methods for object detection generate a feature pyramid corresponding to image data, and rescaling the feature pyramid to a scale corresponding to a median level of the feature pyramid, wherein the rescaled feature pyramid is a four-dimensional (4D) tensor. The 4D tensor is reshaped into a three-dimensional (3D) tensor having individual perspectives including scale features, spatial features, and task features corresponding to different dimensions of the 3D tensor. The 3D tensor is used with a plurality of attention layers to update a plurality of feature maps associated with the image data. Object detection is performed on the image data using the updated plurality of feature maps.
