摘要:
An optical component is provided. The optical component includes an optical-path portion including an arm-connecting portion and a lower portion, a first arm extending from a first end of the arm-connecting portion, and a second arm extending from a second end of the arm-connecting portion. The first arm has at least one resting feature and the second arm has at least one resting feature. The optical-path portion has an input surface. When the resting features of the first arm and the second arm are positioned on a top surface at short edges of a trench in a trench system, the optical-path portion is vertically aligned in the trench.

摘要:
A flexible, rubber-like restraining net (6) comprised of a plurality of communicating cords (8) spaced to form a plurality of apertures (10) to allow the passage of water or gas. Said cords (8) drape over and contact items (14, 16, 18) within a rack (12) so as to prevent dislocation during the application of force. In addition, said cords (8) may contain textures (20, 22, 24, 26) that increase friction with said restrained items (14, 16, 18).
摘要:
A state-based admission control method for networks carrying inelastic applications traffic such as exemplary VoIP traffic. The method analyzes the history of real-time VoIP activities in a network to determine a corresponding control state and applies performance measurement techniques to form the admit/reject decisions for placed VoIP calls.
摘要:
Methods and apparatus are provided for QoS-based admission control (QBAC). The disclosed QoS-based admission control techniques use QoS parameter measurements. An admission control request for a call on a path in a packet network is processed by obtaining performance data for the path; and predicting a performance of the call on the path using performance data for the path. In one implementation, the predicted performance is based on one or more derivatives of the performance data. Typically, the performance data includes historical performance data and is based on at least one quality of service metric.
摘要:
Methods, compositions and kits are provided for assessing angiogenesis through sensitive, direct detection of activation of endothelial cells at molecular levels. In general, activation of endothelial cells is detected by measuring the levels of cellular components and their protein complexes participating in a specific angiogenesis signaling pathway in endothelial cells. The methods can be used for assessing status of diseases associated with undesirable angiogenesis, such as the likelihood of developing the disease, presence or absence of the disease, prognosis of the disease and the likelihood of response or resistance to a particular anti-angiogenic therapy. The methods can also be used to guide the design of effective therapeutic regimens targeting a specific angiogenic signaling pathway, as well as in conjunction with therapeutic intervention of diseases or conditions associated with undesirable angiogenesis.

The present invention is directed to methods and systems for applications relating to correction of numerical data resulting from dynamic changes to a true value. Such methods and systems may be used in accurate and unbiased quantitative polymerase chain reaction measurement.
摘要:
A cover for an electrical outlet is disclosed that prevents insertion of dangerous foreign objects into the sockets of the outlet, which would pose a shock hazard. The cover is configured such that it allows use of either or both of two sockets of the electrical outlet. The cover is further designed such that it is safe for handling by children.
摘要:
Methods and systems are disclosed for scheduling one or more tasks to be performed by a resource modeled as a mathematical group. One or more tasks to be performed by a resource modeled as a mathematical group are scheduled by selecting a coset representative k of a subgroup of the mathematical group based on predefined criteria for homogenization of the one or more tasks. The one or more tasks may comprise, for example, packets and the resource may be, for example, one or more communications links in a packet network. The predefined criteria for homogenization of the one or more tasks includes, for example, a time-based or a size-based homogenization of the tasks (or both).
摘要:
Methods and apparatus are provided for measuring and evaluating access link performance in IP networks that reduce the amount of required test traffic. Performance values supported by access links in a packet network that interconnects regions of an enterprise network are evaluated by (i) obtaining a plurality of test measurements for a set of N access links; (ii) formulating a matrix equation (Ax=D), where A is an invertible matrix, such as a Hadamard matrix, x is a vector of unknown access link performance parameters and D is a vector based on the plurality of test measurements; (iii) assigning one or more numeric values to one or more unproducible equations in the matrix equation based on one or more system properties; and (iv) obtaining a performance parameter value on each directed edge for the set by applying an inverse matrix A−1 to each side of of the matrix equation.
