摘要:
A system and method for providing randomly-generated test cases for a set of interfaces of a piece of software are disclosed. A test case generator is initialized with parameter arrays Sp with cardinality mp and a prime number qp. For each independent parameter p of each of the set of interfaces, a test case number t is generated. A test case is then generated based on the values for each independent parameter p and based on t and Sp, mp, and qp.

Systems and methods consistent with the invention may include receiving an indication that a software error was detected during operation of the application program, generating an error message based on the software error, the error message including an error signature, comparing the error signature with information stored in a patch library database to identify a corresponding correction patch, and correcting, when the corresponding correction patch is identified, the software error by applying the corresponding correction patch.

摘要:
Silicon wafers are first subjected to an oxidative treatment and subsequey to exposure to organosilicon compounds which contain at least one radical in the molecule which is hydrolyzably bound to the silicon and at least one radical in the molecule having hydrophilic properties. Depending on the compound selected, more or less strongly hydrophilic or hydrophobic properties of the silicon surface can consequently be established under mild conditions. The wafers treated in such a manner have a high storage stability and retain their surface nature even under difficult climatic circumstances. The surface nature present after the oxidative treatment can then be restored particularly easily by hydrolysis.

It is possible, by means of a flame-spraying or plasma-spraying technique adjusted to suit the particular properties of a plastic, not only to provide nonreinforced plastics with a uniform coating, but also to achieve an excellent hydrophilic surface wettability at the same time.

This invention relates to an improved process for preparing polysiloxanes having hydrocarbon radicals bonded to silicon atoms via oxygen, by reacting a halosilane with an alcohol and water in the presence of the desired polysiloxane, the improvement which comprises continuously introducing into a reactor equipped with a column and possibly a reflux condenser and the desired polysiloxane, an alcohol, water and, if necessary, an acid catalyst which promotes the condensation of Si-bonded condensable groups, in an amount such that the reactor contains at least 5 percent by weight of alcohol and 0.001 to 5 percent by weight of catalyst, based on the weight of the alcohol, catalyst and polysiloxane present in the reactor in which the contents of the reactor are heated to the reflux temperature and the halosilane is introduced into the column at least one meter above the bottom of the column while continuously removing the polysiloxane from the reactor at the same rate as it is formed.
