Abstract: A method of software defect prediction by a computer is provided. The method comprises identifying software test organizations scheduled to perform testing on an application or applications, where the scope of the software testing varies between different test organizations, identifying the type of test cases to be executed by each test organization, where the test types comprise at least one of new functionality test and regression test, and identifying a planned number of test cases to be executed for each test type. A forecast number of defects are modeled by a computer based on the planned number of test cases to be executed and a defect rate for each test type. The development staffing level capable of fixing forecast defects by the scheduled completion of testing is calculated by the computer based on a fix capacity of a software development organization. Development resources are assigned to fix defects based on the calculated development staffing level.

Abstract: A hybrid utility vehicle includes a tool-supporting frame and an electrical power source driven by an engine. Right and left rear wheels independently driven by permanent magnet electric motors and front wheels electrically steerable over a range of approximately 180 degrees operate under the control of a vehicle controller responsive to steering and speed input controls to provide zero turn radius operation with minimum slippage and tire scuffing. Space efficiency provided by the electric steering and an electrically driven tool deck facilitate a variety of tool mounting configurations including a rear discharge deck with a chute passing under the vehicle frame between the driven wheels. An inverter connected to the electrical power source provides 110/220 volt output. The power source also functions as a high powered, high rpm, low noise starter motor.

Abstract: A control system for a cutting reel unit includes a height-of-cut adjusting system and a reel-to-bedknife clearance adjusting system. The reel mower cutting unit may be manual or self-adjusting. In the manual mode, adjustments can be made by engaging and turning an adjustment actuator on the side of the cutting reel with a hand tool such as a socket wrench. In the self-adjustment mode, adjustments can be made by engaging and turning adjustment actuators with an output shaft of an electric motor. The same adjustment actuators are used in both adjustment modes, and the reel cutting unit may be converted between modes by fastening or unfastening electric motor assembly from the unit.

Abstract: A mobile transmitter transmits a transmission signal from a vehicle to beacons. An estimator determines elapsed times for corresponding propagation paths between the vehicle and the beacons. Each propagation path includes at least one of a first propagation duration of a transmission signal and a second propagation duration of a return signal. A compensator compensates for noise or measurement error associated with a corresponding propagation path by invoking a linear fit scheme. The linear fit scheme applies a generally linear fit over fixed intervals of noisy measurements such that the noisy position measurements generally conform to a linear portion of a path plan of a vehicle. A data processor estimates a position of a vehicle at a confluence or intersection of the position curves or temporal curves based on elapsed times for the propagation paths.

Abstract: A method and system for determining the position of a vehicle comprises a transmitter or transceiver for transmitting a transmission signal from a vehicle to beacons associated with the work area. A data processor determines an elapsed time including at least one of a first propagation duration and a second propagation duration. The first propagation duration refers to a propagation time of the transmission signal from the vehicle to the particular beacon; the second propagation duration refers to a propagation time of a return signal from the particular beacon to the vehicle. A compensator compensates for the following associated with the transmitter and the particular beacon: bias delay, noise, and measurement error. A data processor processes the elapsed times into corresponding position curves or temporal curves to estimate a position of a vehicle at a confluence or intersection of the position curves or temporal curves.

Abstract: A time estimator determines a first aggregate elapsed time between the transmission of the first transmission signal to a first beacon and receipt of a return signal, a second aggregate elapsed time between the transmission of the first transmission signal to a second beacon and receipt of a return signal, and a third aggregate elapsed time between the transmission of the first transmission signal to a third beacon and receipt of a return signal. A bias compensator compensates for bias delay associated with at least one of the first transmitter, the first beacon, the second beacon and the third beacon. A converter converts the first aggregate elapsed time, the second aggregate elapsed time, and the third aggregate elapsed time into position curves. A data processor estimates a position of the vehicle at a confluence or intersection of the position curves.

Abstract: A transmitter at a lead vehicle transmits a first transmission signal toward a first beacon and a second beacon associated with a following vehicle. A data processor or estimator determines a first propagation time associated with the first transmission and the first beacon and a second propagation time associated with the first transmission and the second beacon. A vehicle controller controls a heading of the following vehicle to maintain a first distance substantially equal to a second distance (i.e., first propagation time substantially equal to a second propagation time) or a first distance that deviates from the second distance by a predetermined maximum amount.
