A software code optimizer automatically detects inefficiencies in software code and corrects them. Generally, the software code optimizer converts software code into a graph representing the workflows and relationships in the software code. The graph is then converted into vectors that represent each workflow in the software code. The vectors are assembled into a matrix that represents the software code. The matrix may be stored in a cluster in a database as an example of optimized software code or be compared with other matrices stored as clusters in the database to determine whether the software code is optimized. The software code optimizer can change the software code to be more efficient if a matrix for an optimized version of the software code is found in the database.

A data-instantiator method handle is configured to create a target object based on a stream object. One type of data-instantiator method handles is a Stream Object Processor method handle (SOP_mh). A SOP_mh is a runtime-computed constant in a runtime constant pool. A runtime environment resolves the SOP_mh lazily responsive to a request to access the SOP_mh. The runtime environment invokes the SOP_mh to create a target object based on a stream object. By virtue of being a constant in the runtime constant pool, the SOP_mh is a candidate for optimization by a dynamic compiler in the runtime environment. The dynamic compiler may elect to constant fold the value of the SOP_mh and inline any code or executable logic that the SOP_mh refers to.

The invention discloses a MIMO different-factor full-form model-free control method with parameter self-tuning. In view of the limitations of the existing MIMO full-form model-free control method with the same-factor structure, namely, at time k, different control inputs in the control input vector can only use the same values of penalty factor and step-size factors, the invention proposes a MIMO full-form model-free control method with the different-factor structure, namely, at time k, different control inputs in the control input vector can use different values of penalty factors and/or step-size factors, which can solve control problems of strongly nonlinear MIMO systems with different characteristics between control channels widely existing in complex plants. Meanwhile, parameter self-tuning is proposed to effectively address the problem of time-consuming and cost-consuming when tuning the penalty factors and/or step-size factors. Compared with the existing method, the inventive method has higher control accuracy, stronger stability and wider applicability.

A new and improved method and apparatus for use in conjunction with the free floating paving screed used for road paving is disclosed. The method of forming a bituminous mixture into a smooth flat paved mat comprising some areas with a given nominal mat density and some selected areas with a predeterminedly higher mat density is described wherein problems posed by a reduced compaction ratio occurring subsequently to paving the mat where the roller drum bridges over recesses in the subbase are addressed. The modified paving screed described employs a new adjustable screed plate that allows localized areas of increased angle of attack and a device to increased material entry density in localized areas in front of a screed plate leading edge. Either method is used to create an increase in mat density in the desired area. The method and apparatus teach that by pairing differences in compaction ratio that inherently occur due to subbase irregularities with correspondingly predetermined and different mat densities in the paved mat, a good consistent final density can be achieved notwithstanding the limitations of the compaction rolling. A forward looking vision system is described that identifies subbase recesses, a digital controller quantifies the density increase required, and a GPS system maps locations where the mat density increases are to be applied.

Aspects of the technology relate to temperature regulation for high altitude, long duration balloons, such as balloons that operate in the stratosphere for weeks, months or longer. A balloon covering overlays the balloon envelope, providing an opaque or otherwise light-reflective layer with low emissivity that blocks or reflects optical and/or infrared light. Heat from within the envelope is reflected back from the covering toward the envelope, while light from the sun is reflected back towards the environment. An active venting system is employed to draw in cooler ambient air from the external environment while expelling warmer air from within the envelope. Vent and air intake assemblies of the active venting system are actuated in view of current and/or predicted balloon conditions to regulate internal balloon temperature. This approach reduces repeated pressure changes, which can put undue stress on the balloon envelope and adversely affect the operational lifespan of the system.
