Abstract: The present disclosure relates to paper microfluidic devices for use in combination with a viewing box assembly for imaging and rapid identification and quantification of target analytes in a fluid sample that is deposited onto the device such that one or more target analytes in the sample react with one or more diagnostic components on the paper, causing a detectable reaction. The reacted microfluidic device may then be placed inside an opaque viewing box having an internal light source and top panel viewing aperture through which the microfluidic device may be imaged using a mobile electronic device and graphical user-interface for purposes of detecting and quantifying the one or more target analytes. In some embodiments, the microfluidic device includes diagnostic paper and abase. In some embodiments, the microfluidic device includes a filter layer on top of diagnostic paper layer.

Abstract: A client utilizes a backchannel messaging infrastructure and information matching logic to measure server performance characteristics at the client without requiring the server to correlate command responses to command requests. The backchannel messaging infrastructure facilitates the sending of messages between clients, and allows a client to send to the interested clients messages containing an activity start timestamp and identifying the requested activity when sending a command request to a server. The information matching logic enables each client to measure server performance by matching command requests, as indicated by the backchannel messages, and command responses based on message types, identification of the sender (i.e., the client that generated the original command request), and identifier attributes that are unique to the command requests and command responses.

Abstract: A facility executes on a central computer system and applies a time-varying load to an application program under test (AUT). The facility executes in a multiple number of modes or hierarchical levels as dictated by information provided in its configuration file. An instance of the facility executing at the highest or first-level of the hierarchy is responsible for spawning numerous subordinate or second-level instances of the facility on, for example, remote computer systems. These second-level instances of the facility may spawn additional subordinate or third-level executors on the same or remote computer systems. Ultimately, the lowest-level or leaf instances of the facility are spawned, and these leaf instances of the facility are responsible for launching the client test program instances that are used to test the AUT.
