Abstract: A method embeds a watermark image into a host image with adaptive rectangular partition and Lower Upper (LU) decomposition such that a watermarked image is generated with improved computational complexity. The method divides a host image into an Red (R) component, a Green (G) component, and a Blue (B) component, and divides each component of the R, G, and B components into a plurality of M×M size blocks, and partitions each of the plurality of M×M size blocks into a plurality of non-overlapping blocks with adaptive rectangular partition. The method selects a plurality of embedding blocks from the plurality of M×M size blocks for each component of the R, G, and B components of the host image to embed watermark information such that the watermarked image is generated.

Abstract: A MAC protocol, useful for WLANs, is provided for random access over a channel. The protocol includes three concurrent processes. The channel includes a contention subchannel and a transmission subchannel. In the contention process, all nodes use the standard RTS/CTS mechanism operated on the contention subchannel to contend for a transmission right. When one node gains the right, all the nodes store the contention result into their respective contention queue (CQ) buffers. In the transmission process, the nodes sequentially transmit their data over the transmission subchannel according to the order of the nodes stored in the CQ buffers. When one node finishes transmission, the CQ buffers are updated. The contention and transmission processes are connected by the queuing process for dynamically updating each node's CQ buffer. When OFDM is used in a random-access system, numbers of data subcarriers in both subchannels for maximizing the system throughput are given.

Abstract: One example embodiment is a method to embed a watermark image into a host image such that a watermarked image is generated. The method divides a host image into an Red (R) component, a Green (G) component, and a Blue (B) component, and partitions each component of the R, G, and B components into non-overlapping blocks from which embedding blocks are selected to embed watermark information such that a watermarked image is generated.

The carbohydrate composition of the present invention extracted from Panax ginseng shows exceptional cardio-protective effect and, thus, provides a highly advantageous and highly promising treatment option for treatment of ischemic conditions and prevention of ischemia-reperfusion injury. The present invention further provides a method of protecting cells against hypoxia and reoxygenation induced cell death. Still further, the present invention provides a carbohydrate composition extracted from Panax ginseng and a pharmaceutical formulation comprising it.

Abstract: For sustainable development, a refinery is required to save energy as much as possible so as to reduce the emission of greenhouse gas. In crude oil operations, oil transportation from storage tanks to charging tanks via a pipeline consumes a large portion of energy. It is vitally important to minimize energy consumption for this process. Since the oil flow resistance is proportional to the square of oil flow rate, the relation between energy efficiency and flow rate is nonlinear, which makes the problem complicated. The present invention addresses this important issue by formulating a linear programming model for the considered problem such that it can be efficiently solved. A real-world industrial case study is used to demonstrate the applications and significance of the proposed method.

Abstract: A method for creating an image includes identifying data representing an overlapping region in each of a first set and second set of image data, wherein the first and second sets of image data are arranged to represent a first image and a second image respectively, and at least one common feature in both the first image and the second image is identified in the overlapping region. A portion of the data representing a portion of the overlapping region in each of the first and the second sets of image data is discarded to obtain a first set and a second set of modified image data. The first and the second sets of modified image data are combined to a third set of image data arranged to represent a third image including at least a portion of each of the first image and the second image.

Abstract: A computer system executes a method that detects an edge of an object with a Canny operator. The method calculates a gradient strength of pixels of the image and applies non-maximum suppression to the image to avoid spurious responses to edge detection. The image is divided into multiple partitions based on a brightness distribution of the pixels in the image and a set of dynamic threshold values. Multiple images for the partitions are superimposed to detect an edge of the object.

Abstract: A method for treating a subject suffering from a neurodegenerative disease includes administering at least one triterpenoid which can be obtained from Hedera helix. A method for treating a subject suffering from a neurodegenerative disease includes administering an effective amount of a Hedera helix extract which comprises the triterpenoid. The neurodegenerative disease is preferably but not exclusively Parkinson's disease or Huntington's disease. Methods for extracting the triterpenoid from Hedera helix and a method for inducing autophagy in cells by contacting them with the triterpenoid are also provided. The triterpenoid allows an exceptional induction of autophagy, in particular a significant reduction of the protein level of mutant huntingtin, a significant reduction of the protein level of A53T α-synuclein, a significant inhibition of the oligomerization of α-synuclein and a significant inhibition of the inclusion formation of huntingtin via the AMPK-mTOR dependent autophagy inducing pathway.

Abstract: A computer system executes hierarchical MK splines for scattered data approximation. The computer system constructs an image by generating a final approximation function that approximates a scattered data set with a hierarchy of control lattice from coarsest to densest. The method includes executing MK splines approximation to the scattered data set with the hierarchy of control lattice to iteratively obtain approximation functions. The image is constructed by generating the final approximation function to construct an interpolated surface.
