 How the Java virtual machine handles method invocation and return
When the Java virtual machine invokes a class method, it selects the method to invoke based on the type of the object reference, which is always known at compile-time.
On the other hand, when the virtual machine invokes an instance method, it selects the method to invoke based on the actual class of the object, which may only be known at run time.
The objectref and args (or just args, in the case of a class method) must be pushed onto the calling method's operand stack by the bytecode instructions that precede the invoke instruction.

 HOOD book sample
HOOD is an architectural design method, helping a designer to partition the software into modules with well defined interfaces that can either be directly implemented or further partitioned into modules of lower complexity.
HOOD was developed as a design method, with special consideration for other development activities that occur at the same time: smooth integration with requirements analysis, concurrent development of independent parts, automated code generation and testing, client-server and post-partitioning support.
HOOD concepts can be described using UML, adorned with a number of ad-hoc stereotypes, and the HOOD method itself can be described using UML as a meta-model, the same way as UML is itself described using its own meta-model.

The subtraction method and the flow hood method measure leakage at different pressures; therefore the results are not directly comparable.
The two primary ratio test methods are the Blasnik and the "Half Nelson." The first quantifies the relationship between the leakage to inside the envelope and the leakage to outside the envelope.
This procedure is part of a method of estimating leakage flows without the use of a flow hood, Duct Blaster, or blower door.

 Chapter 3: The effect of an extraction hood - Emissions of Rural Wood Burning Cooking Devices - PhD Thesis: Energy, ...   (Site not responding. Last check: 2007-10-23)
One of the problems with placing a stove under a hood is "the potential for the mechanically induced air flow to change the combustion characteristics of the stove" (Ahuja et al 1987:250).
The chamber method, where the effect of the stove concentrations are measured in a dilution chamber and the source emissions are calculated (Ahuja et al 1987), was developed in response to perceived difficulties with the hood method.
The mathematical methods as well as some definitions relating to an analysis of variance (such as factors, levels, and null hypotheses) are covered briefly in Appendix C.

 Metabolic Monitor
There are three methods of accomplishing expired air collection, namely [1] via a mouthpiece or a face mask; [2] within a hood or canopy positioned over the head or the upper body; and [3] from a totally enclosing body chamber which has discrete inlet and outlet ports.
The relationship of the forced flow rate to the-subject's level of ventilation is of considerable importance in the flow-through technique, as is the size of the hood, canopy or chamber which encompasses the subject.
Air is drawn into the hood either through a designated inlet or through the interstices of the hood as it invests the body of the test subject.

 Flux Hood - Emission Isolation Flux Chamber - Gaseous Emissions from Area Sources
The flux hood sapling method (also called flux chamber or isolation chamber sampling method) has been used to measure air emissions from surface impoundments like landfill and contaminated sites.
Emission isolation flux chamber sampling method is US EPA recommended method to estimate gaseous emission rates from area emission sources.
The flux chamber method was found to be a reliable method for measuring volatile organic emissions from surface impoundments.

 Welcome To Home Energy Magazine Online
The ASTM flow hood measurement protocol consists of two blower door pressurization tests, one that measures the leakage of the supply ducts, and another that measures the leakage of the return ducts.
Again, for the flow hood measurements, direct measurements of duct pressures--not just the pressure of the indoor space--for determining duct leakage characteristics are just as important as with the blower door method.
Although we observed no significant bias between the two methods, the flow hood method seemed to be superior because of better internal consistency between pressurization and depressurization results, and it does not render impossible results such as negative leakage figures (see Table 1).

 Chapter 6: The simulation of a dilution chamber - Emissions of Rural Wood Burning Cooking Devices - PhD Thesis: Energy, ...   (Site not responding. Last check: 2007-10-23)
The method was developed in an attempt to reduce the cost and complexity of measuring emissions, and avoid some of the errors assumed to have been caused by suspending an extraction hood above a stove.
The method was the same as that described in Chapter 3 (where the stove was refuelled during the test and 2 litres of water was heated and simmered for 30 minutes, no pot lids were used).
Of the two methods compared for calculating emission factors from data collected in chamber tests the accuracy of the least squares method deteriorates with increasing air exchange rate and that of the simple mean method improves.

 Question about Barrel hood fit method. - 1911Forum
1) The length of the barrel hood should be long enough to create an almost crush fit between the front of the first (rear most) barrel lug and rear of the hood, regardless of whether the gun is in battery or disassembled on a bench.
2) The length of the barrel hood should be set so that when the gun is assembled and in battery, there should be a.001 gap between rear of the barrel hood and the slide.
As for the hood area he believed the same as Bob and Chris that the end and sides of the hood should be a snug fit with light drag on the end of the hood.

 PARTIAL SOIL STERILISING WITH STEAM AIR MIXTURES - SOME EXPLORATORY EXPERIMENTS
However, in all these methods the use of pure steam has inevitably led to the soil being heated locally to the steam temperature to that optimum sterilising conditions are not attained.
The rigid hood method shows promise for use on a practical scale, but is not sufficiently developed yet for commercial use.
Injection methods, such as buried or spiked pipes etc., were ineffective because of the low mixture pressure available from the injection type steam-air mixer unit (or from any normal rotary blower or fan).

 A Survey of OO Methods
His method also discusses a project-independent role, that of the object-oriented domain analyst, whose organisation is responsible for the identification, development, marketing, and demonstration of reusable components in conjunction with the projects.
After all, this is the method used with data flow diagrams starting from a context diagram which shows all the external interfaces with one central process.
Although Jacobsons OOSE design method is not particularly strong, his view of the system in terms of use cases is a powerful method for analysing the system in terms of the demands made of the system, and the processing that is required to meet those demands.

 Squawkbox Noise » Robin Hood is Dead. LONG LIVE ROBIN HOOD
I have been listening to all this ballyhoo that the "Robin Hood" method of school funding that takes local tax revenue away from property-wealthy school districts and shares it among property-poor districts is now dead.
In what’s being called a new "enrichment" tier, wealthy districts can have access over the next few years to as much as 6 cents on their tax rate without any "Robin Hood" sharing, as long as the state guarantees other districts as much money per student as the Austin district enjoys.
There are circumstances that would allow the old method of "Robin Hood" funding to return.

 8th International Conference on Reliable Software Technologies - Ada-Europe 2003   (Site not responding. Last check: 2007-10-23)
In the niche market that the HOOD method addresses (notably aerospace and transport), its specialised derivative HRT-HOOD has, over the last few years, increasingly earned the reputation of being "the" answer to the demands from the development of time-critical systems.
The massive advent of UML presents the HRT-HOOD community with a threat and an opportunity: the threat that the irresistible thrust of the new trend obliterate the methodological value of the old; the opportunity of riding the UML wave, with its large offer of support technology, while trying to preserve the unique strengths of HRT-HOOD.
Finally, which should be of major interest to the Ada community, this paper presents its strategic choice to view the Ada Ravenscar Profile as the target language for the automated code generation capability attached to the method.

 [No title]
As part of this exercise, a new design method and a set of associated tools have been developed to support the design of time-critical systems.
This has resulted in the definition of the HRT-HOOD design method which builds on the foundation of HOOD and augments it with features especially suited for the design of hard real-time (HRT) systems: abstractions, attributes, rules and constraints that support the definition of an HRT design analyzable against timing requirements.
The terminal objects of the architecture that belong to the hard real-time component of the system are either passive or sporadic (to model a-periodic activities) or cyclic (to model periodic activities) or protected (to encapsulate resource control mechanisms).
