What is the definition of Cp and Cpk in Statistical process control?
Cp is the capability of a process and Cpk is the actual capability of a part running in the process. The only way Cp = Cpk is if the process mean is exactly centered which is seldom the case in manufacturing. Therefore, Cp > or = to Cpk.
What is difference between capabilities list and access list?
1. Access Control ListsAn ACL system has at least five namespaces whose relationships need to be considered:The namespace of file names: /tmp/fooThe namespace of unique object identifiers: (dev 22, inode 36, type file)The namespace of user identities (uid 52476)For each object type (file, disk, terminal, ...), the namespace of operations that object can perform.The namespace of process identifiers (process 719)In an access list system, it is assumed that there are two global mappings:principal: process identity -> user identityfs_lookup: file name -> object identity That is, every process has an assigned user identity and every file name can be translated into a unique object identifier. Hanging off of every unique object is a further mapping:acl: (object identity, user identity) -> operation(s) Given a process proc that wishes to perform an operation op on an object object, the protection mechanism in an access list system is to test the following predicate:op in acl(object, principal(p)) In the special case of the "open" call, this test is modified to be:op in acl(fs_lookup(filename), principal(p)) 2. Capability SystemsA capability system has at least four namespaces whose relationships need to be considered:The namespace of unique object identifiers: (dev 22, inode 36, type file)For each object type (file, disk, terminal, ...), the namespace of operations that object can perform.The namespace of process identifiers (process 719)The namespace of capabilities (object 10, operation set S)In a capability system, it is assumed that there is one local mapping for each processcap: (process identity, index) -> capability That is, every process has a list of capabilities. Each capability names an object and also names a set of legal operations on that object.There are also two "accessor" functions:obj: capability -> object identityops: capability -> operations Given a process proc that wishes to perform an operation op on an object object, the process must first possess a capability naming that object. That is, it must possess a capability at some index i such thatobject == obj(caps(p,i)) To perform an operation, the process names the "index" iof that capability to be invoked from the per-process list. The protection mechanism in a capability system is to test the following predicate:op in ops(caps(p,i)) Capability systems typically do not have a distinguished "open" call.3. Some Differences This section is incomplete.Simply comparing the predicates shows that there is a significant difference between the two systems:ACL: op in acl(object, principal(p)) Capability: op in ops(caps(p,i)) An obvious difference is that the capability model makes no reference to any notion of "principal".Another obvious difference is that the capability model has a parameter "i". This allows the process to specify whichauthority it wants to exercise, which is why only the capability model can solve the confused deputy problem.
How do you find the density if only the volume is given?
The formula to find the density is d=m/v
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
What is special capability on dark orbit?
Only Goliaths with special Designs have it.
Do you have to pay monthly for the Ipad2?
You only have to pay if you buy it with 3G capability
Infants can survive only on breast milk?
No,they can also be given baby formula. Yes, they can survive on a diet of nothing but breast milk.
Do digital cameras come with memory cards?
No, some have only on board memory capability, it is the better cameras that have expandable memory capability.
Can you make videos on the iPhone?
No. You can only take pictures, no video capability exists.
How to determining the optimum RAM Speed for a given CPU Is there a formula for Determining optimum RAM speed for a given CPU?
Max it out!!! The CPU can only be as fast as it's cache size and than it's memory.
Is there a formula for finding the length of a square with only the area?
Yes, if it is a square the Area=A=l2 where l is the length and If you are given the area, then l=square root (A)
What is it to Evaluate a formula in math?
to solve the equation In math there are many formulas, for example the area of a circle is given by the product of pi and the square of the radius of the circle. This is the generalized formula and holds good for any value of the radius. However, there is one and only one value of area for a given value of the radius. Similarly the area of rectangle is the product of its length and breadth. This is the generalized formula and holds good for any value of length and breadth. However, there is one and only one value of area for a given set of length and breadth. The roots of a quadratic equation are given by a well known equation and gives a positive and a negative value for the answer. Both values are valid even though the negative value may not make sense under a given circumstance and is discarded. There are many such examples. The act of finding the results for a formula for a given instance is to EVALUATE.
