Questions on composition and assosiation relationship

Which two are true about the composition relationship "A Blip consists of many
Blipverts."? (Choose two.)
A. A Blip must have at least two Blipverts.
B. A Blipvert can be a part of only one Blip.
C. A Blipvert must be part of at least one Blip.
D. When a Blipvert is deleted, its Blip should also be deleted.
E. When a Blip is deleted, each of its Blipverts should also be deleted. Answer: BE
according to me its answer shud be C and E. as composition says that one can not exsit without other..means blipvert can not exist without blip..hence it must be part of atleast one blip..
but actual answer given in book is B and E.
Can some one explain.
Question on Assosiation
Which is true about association navigation?
A. Association navigation is meaningful for only OO design, NOT implementation.
B. Association navigation is used to describe the relationship between a subclass and its superclass.
C. Association navigation indicates which direction a relationship can be traversed.
D. Association navigation indicates how many instances of each object type are involved in an association.
Answer should be C and D....D because we mention the how many instances can one have of other....example 0..1, 1..* etc etc...so D should also be an answer
but in book it is only C..
can someone explain this.
Am i wrong in my explanation?...
Thanks

Some question on pa and om

hi
some question
if employee work in us and then gone to uk
how u track
it
whcin infotype
and what is dotted reporting
in simple mantice
and how to assign diff number range in org mangemnt for job, postion and org unit like 200-300,100-200,400-500.
from
rajani

Hi Rajani,
To address dual reporting relationship ,OM has A/088 relationship,please check tcode -OOOT and select object type S-Positions and essential relationship.
OONR is tcode for number ranges -the first two letter in the subgroup denotes the plan version and the last two letter is the object type
for ex -01S-would denote plan version 01 and object type S-postion and whether the numbers are going to be asisgned internally by the system or externally by the user.
01$$ would denotes its application for all object types,should the $ be used .
select the subgroup and click on number range maintainance and you will be able to see the numbers assigned or edit them by clicking change interval button and you can assign the from and to number accordingly.The numbers gets assigned when the particular object is created.
ex-you assign the subgroup as $$S-which means its for all plan version and object type S
when you create an object type using PP01 for ex the numbers gets assigned for that object created.
Hope this helps.
Regards

AE CS6 - 3D Compositing and Color Correction workflow

AE CS6 - 3D Compositing and Color Correction workflow
Hello everybody,
I have some questions about work flow in AE concerning compositing and Color Correction. I saw many tuts about (f.e. Lynda.com Premiere Pro Color Correction and Enhancement... and tuts by Andrew Davis here in creative.cow).
Essentially, he have this CC work flow:
GRADING (primary and secondary)
Adjusting Tonality (Brightness and Contrast)
Adjusting Colors (White balance and fix color dominance)
MATCHING
Conforming colors of different clip shoted with different camera and lighting set up.
ENANCHING LOOK
Giving to all clips a unique "look"
But what does it happen if we have NOT just some clips but ALSO a 3D object (rendered in a 3d sw or, actually also a 3d object inserted by 3D Element by videocopilot)
or/and
a keyed clip from a green screen shot?
How does this footage (3d object and green screen keyed shot) transform
the aforementioned work flow?
We have to consider that this footage (3d object and green screen keyed shot) must to be pre-multiplied to make a right compositing but when you make CC it must be again "straight"... (NOT pre-multiplied)
Is really hard also understand how dale this work flow between AE and Pre Pro if you want to make CC in Pre Pro after compositing in AE.
I try to present a work flow for this (very common) situation:
I have a landscape clip as a background
a keyed clip (pre-multiplied) with a Character watching sky
and a 3d (pre-multiplied) object U.F.O. on sky.
When I have done compositing, how make I a right CC of all footage if I have two clip (3d object and green screen keyed shot) still pre-multiplied?
I think, but I'm not sure, that should be a good idea to send to Pre Pro a composited Comp with separate layers (by dynamic links) to have all single separate layers (Background, 3d object and green screen keyed shot.. but also the Color Warping...!). Than, in Pre Pro you should make a CC (Grading) just for a BG and than try to Match (Matching) this color corrected BG with 3d obj and keyed shoot. But we have a problem at this point cause our 3d object and green screen keyed shot are still pre-multiplied, and before make matching we have to re- multiplied theme, but how? And if we re pre-multiplied them, compositing will be also right?
Or maybe, before exporting comp from AE to Pre Pro, he have to create both layers for 3d object and green screen keyed shot, one pre-multiplied and one "Stright"? But, again, how to combine them to have a right compositing and a a right CC?
Anybody can help me to understand or maybe suggest any tuts to dale this common issue in AE- Pre Pro?
Many, many thanks!

Dave is correct. (And so is Mylenium. No need to be rude, when he was jsut trying to explain that you were introducing unnecessary complexity.)
The color matting is removed to interpret the alpha channel when you import the footage. After that, any color correction that you do to a layer based ont hat footage item doesn't have anything to do with whether the channels were straight or premultiplied for the source item.
You color-correct your individual items to amke them match as part of the compositing process in After Effects. Then, if you want to do a color grade of the shot in Premiere Pro along with other shots, you'd be working on the single rendered/flattened composite, so the details of the original elements that went into the composite are irrelevant.

Composition and Aggregation

hey guys
I have read the previous posts about composition and aggregation. And here is what i have got.
Composition: life time of objects got to be the same. For example there is a composition between carframe and a car. If the car gets destroyed the carframe woulod also get destroyed.
Aggregation: Life times of the objects are not the same, one oject can live even after the other object has been destroyed.
But i seem to get all these things in theory, but when it comes to coding am not able to translate these theories. To be particular i would want someone to help with me how these relationship can be coded
Thanks
K

Consider the following example :
Car has an engine, chairs, wheel, etc. it is clear
that this is composition, because "Car" is composed
of engine, chairs wheel and so on. but think about
what happens if you want to destroy the car, but
reuse its engine, thing that frequently happen when
you get your car smashed (didn't happen to be thanks
god). Anyway you destroy the car, but it parts stay
alive. so the "composed" objects lifetime can exceed
the "composer" object lifetime.
I think of composition and aggregation in the
following way :
if there is no meaning to the object without its
parts (parts of which it is
composed) then it is composition. if there is any
meaning for the object without its parts (like empty
paragraph (without words) in text, which can be left
empty till the wrighter have something to write in)
well, then it is aggregation.sometimes a car could be smashed and the engine would still be running, junkyard sells tires from wracked cars... all tha, however, has nothing to do with composition or aggration.
composition is a strong form of ownership, a car probablly needs to have an engine, some tirs etc in order to be sold as a car, so the engin, tirs are usually composed as composition. life time of them begins when the car is instantiated and until the instance vanishes. when a car is smashed or totaled, it is merely a state of the car instnace, like a flat tire, the car instnace still exists, so a running engine on a totaled car is ok.
usually if your object has a field referencing an object, that object is a composition, even the creation occurs earlier that the creation of the instance itself, such a case would be a DI: dependency injection. the destruction of an instance is a bit beyond the control of the composing instaance, that however dosnt matter, once the field loses the reference, we can think of it as the end of the life of the composed object. this is a bit different from C++ which allows you to invoke the destructor of the composed object. another difference is that you can have local objects, java objects all live in the heap area, no local objects.

UML: Composition and its implementation aspect?

UML: Composition and its implementation aspect using a Nested Class (Is it always or depends or is there another equivalent way?)
1. I read this thread: http://forum.java.sun.com/thread.jsp?forum=425&thread=306033&start=0&range=15&hilite=false&q=
2. Now, basically I want to understand:
a. If a nested class is NECESSARILY a form of composition? Or it depends on the meaning of the presented code and/or the meaning of the requirement?
b. When there is a composition, should we ALWAYS model it using a nested class and in which case/scenario/example, the choice of nested class is justifiable AND mandatory?
c. Is there any example that the Composition can be implemented by nested class (es) as well as non-nested class? (Equivalent way)
d. Depends on c., if there is a choice between a nested class and non-nested class? Which is better and from what angle?
3. 1M Thanks.

When you say nested class, I interpret that as a Java inner class.
If that's true, then I don't think that composition is always modeled as an inner class. It's more likely to be a simple private data member that's a public class type.
I usually see composition as a non-nested class. In his "UML Distilled", Martin Fowler says aggregation is the part-of relationship. Composition is a stronger variety of aggregation, where the part object may belong to only one whole and lives and dies with the whole.
So if you have a Polygon class that has a Collection of Points as member data, that's composition. No inner classes in sight. - MOD

Composite and aggregation code example - is this correct

after reading all the aggregation and composition of this forum threads, i would like to know whether this is the corect understading in java implmentation of composite and aggregation.
example of aggregation
public class Money{}
public class Wallet {
private Money money;
public Wallet(Money money) {
this.money = money;
example of composite
public class Heart {}
public class Human {
private Heart heart;
private Human() {
heart = new Heart();
the aggregation implementation is based on the idea " The instance of aggregated class can be shared by many other classes. While those classes are deleted, the instance of aggreated class won't be deleted."
hence, i create money object outside the wallet, the passed the money into the wallet to make them "has a" relationship.
the composite implementation is based on the idea " the instance of composited class can only be used by one other class. While that class is deleted. The composited class will also be deleted."
hence, the creattion of heart is done by the human constructor it self.
1. is this the only ways to do the implementation for composite and aggregation?
2. is there other implementations for aggregation, the money class is constructed inside the wallet class?
3. is there other implementations for composition, the heart class is constructed outside the human class?
thank you very much!

Your abstractions are quite good.
1. is this the only ways to do the implementation for composite and aggregation?Broadly speaking yes, there are as some subtle variations, but you examples illustrate the key distinction.
2. is there other implementations for aggregation, the money class is constructed inside the wallet class?Yes, in practice you should also have methods to add and remove from an abstraction, so Wallet should have Wallet.add(Money) and Wallet.remove(Money) methods. You should also consider multiplicity, which may require that you use Qualified Classes and/or Associative Classes to implment an aggregation.
No, you should not construct the Money inside the Wallet. If you find you want to do this you should consider changing to a Composite.
3. is there other implementations for composition, the heart class is constructed outside the human class?Yes, it is usual to pass a this from the Composite (Human) to the part (Heart) when you construct it because Composition is implicitly a bi-directional relationship.
No the part of a composite should not be constructed outside the composite.

Question regarding standby and cables...

I just got FIOS yesterday and so far (one day lol ) I love it. I love the speed of my internet. I was paying for BOOST and in the beginning I was getting 3.5mb daily but over the last 4 months that has become 500kb and I had had enough.
On to my problem. I have the new Motorola MRDVR HD in the livingroom and the 7100 p2 STB in the bedroom. Last night watching a movie in the livingroom (HD) it failed, I restarted and it played, failed again and restarted then all seemed fine but in the bedroom I have a bigger problem.
I understand the 7100p2 does standby and thats fine but I haven't bought a new TV yet so I am using an Epson projector with COMPOSITE cables. I suspect the standby and composite cables are not playing nice but while watching anything 20-30 min in the STB just goes off...and the only way to get it back on is to pull the plug on the STB.
I have tried every other iteration of menu/on/off/anything but once it goes into standby ( I guess it is anyway although I was watching something) It will not come back on. Sometimes it tries...black screen for a few then back to the EPson start screen and from there the only way is to pull the STB plug.
If it's a composite cable/projector problem Ill get another TV (the tech is SOOOO old I figured it would work np) but if there is some sort of interaction between the STB and TV that this cannot handle... I have other ways to hook it up but none will get me sound right now, s-video/vga to DVi to HDMI, but none of those will do sound (today anyway).
I have searched all over the webs and cannot find even mention of someone trying to use these old old old cables with a newer STB... help...:-)
EDIT: The motorola starter guide does show composite and s-video but no mention of standby.

Actually the standby is just when you power the cable box off, its not really off, it is in standby waiting incase there is an update. All the Verizon STB's do this.
Component cables have no communication between STB and TV. Only the HDMI cable has any 2 way communication, so there should be no compatibility issue.
If the STB is powering off after 20-30 minutes and you cannot power it back on without a reboot, then I would guess that you have one of two issues (that I can think of anyway).
It could be that the STB is overheating. Its designed to power down when it gets too hot and stay off until it cools down. Is the STB out in the open? Does it have anything on it, like a towel or another electronic device? Is it inside an entertainment center that has an enclosed back or front? If so, it may just be getting hot and you may need to move it out into the open or move whatever is on it.
If its not overheating then it may be just a lemon of a stb, I'd contact Verizon and ask them to swap it out for you.

Question regarding battery and warranty

Hi all! I have a quick question about how and if my warranty applies to my battery. After about a year and a half of ownership (I have the three-year extended warranty), my battery has gone completely down the toilet. It wasn't a problem before, but this year I have to lug my T61p around a lot for lab work. My battery is now rated at... 39.75Wh when it shipped at 84.24Wh. This is a pretty drastic difference. In any case, I don't think that this is covered by warranty, but figured that I'd ask before I drop $180 on a new battery (ouch). And, speaking of, if my suspicions are correct, does anybody know where I might find a 9-cell battery for the T61p? All I'm seeing on Lenovo's website is the one for the N100... which doesn't... match very well. Yaknow.
Thanks a lot!
ThinkPad T61p [June 2008]: 2.5Ghz Penryn Core 2 Duo, 4GB DDR2 RAM, NVidia Quadro FX 570m 256MB, 160GB 7200RPM Fujitsu HDD, 1920x1200 WUXGA Matte LCD, Windows 7 RC1

Is either of these appropriate? I'm wary of the one on Amazon, as there are other (off-brand) batteries that are advertised as being Lenovo ones (though those generally sell for a lower price). The other one just looks like I'll have to call up to buy it.

Question regarding roaming and data usage

I am currently out of my main country of service, and as such I have a question regarding roaming and data usage.
I am told that the airplane mode is sufficient from keeping the phone off from roaming, but does this apply to any background data usage for applications and such?
If the phone is in airplane mode, are all use of the phone including wifi and application use through the wifi outside of all extra charges from roaming?

Ann154 wrote:
If you are getting charged to use the wifi, then it is possible. Otherwise no
Just to elaborate here, Ann154 is referring to access charges for wifi, which is nothing to do with Verizon, so if you are using it in a plane, hotel, an internet cafe etc that charges for Wifi rather than being free . Verizon does not charge you (or indeed know about!) wifi usage, or any other usage that is not on their cellular network (such as using a foreign SIM for example in global phones) So these charges, if any, will not show up on the verizon bill app. Having it in airplane mode prevents all cellular data traffic so you should be fine

Question regarding MM and FI integration

Hi Experts
I have a question regarding MM and FI integration
Is the transaction Key in OMJJ is same as OBYC transaction key?
If yes, then why canu2019t I see transaction Key BSX in Movement type 101?
Thanks

No, they are not the same. The movement type transaction (OMJJ) links the account key and account modifier to a specific movement types. Transaction code (OBYC) contains the account assignments for all material document postings, whether they are movement type dependent or not. Account key BSX is not movement type dependent. Instead, BSX is dependent on the valuation class of the material, so it won't show in OMJJ.
thanks,

**question regarding 3G and wif**.

I have a question regarding 3G and wifi. I have #G activated as well as wifi, when I go to retrieve mail for example I get a pop up asking me if I want to connect to a wifi network…should I have wifi and 3G activated at the same time, and why am I getting the pop up…
Thanks

You can have them on at the same time, but they will not be used at the same time for data. The order of preference for data is WiFi > 3G > EDGE > GPRS. You're getting the pop up, most likely, because you have Settings > Wi-Fi > Ask to Join Networks set to ON. You can set that to OFF, and the iPhone will still join known (i.e. previously used) WiFi networks automatically.

Question regarding Dashboard and column prompt

My question regarding Dashboard and column prompt:
1) Dashboard prompt usually work with only for columns which are in subject area. In my report I've created some of the columns which are based on other columns. Like I've daysNumber column that is based on two other columns, as it calculates the difference of two dates. When I create dashboard prompt I can't find this column there. I need to make a prompt on this column.
2)For one of the column I've only two values 1 and 0. When I create prompt for this column, is it possible that in drop down list It shows 'Yes' for 1 and 'No' for 0 and still filter the request??

Hi Toony,...
I think there was another way of doing this...
In the dashboard prompt go to Show option > select SQL Results from dropdown.
There you need to write your Logical SQL like...
SELECT CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END FROM SubjectAreaName
Here.. Periods.Year is the column which is already exists in repository's presentation layer..
and difference of date functionality is the code or formula of column which you want to show in drop-down...
Also write the CASE WHEN 1=0 THEN PERIODS.YEAR ELSE difference of date functionality END code in fx of that prompt.
I think it helps you in doing this..
Just check and inform me if it works...
Thanks & Regards

Composite and S-video

Does the 2009 mini support composite and/or s-video. If so, which cable would work best?

And no thnks to APPL for this terrible decision, worse for not making it clear up front!
It clearly states in the product description on their website what video options it supports.
We are now in the HDTV age so it is understandable that apple are not supporting legacy devices.
The same thing happened when apple stopped using their proprietary monitor connections and then again when they no longer supported ADC connections.
Technology moves forward all the time it a fact of tech life but unfortunately although this suits the majority there will always be a few that are disappointed.

Questions on SPINCOUNT and Semaphores

Hello,
I have a few more questions on SPINCOUNT and semaphores.
1) The documentation states that SPINCOUNT = 0 (default) uses the spincount "built into the delivered binary".
- How can I find out what the built-in spincount is?
- What is the built-in spincount for a native client?
2) "Semaphore appears stuck" (Q_CAT 1447) is reported when the semaphore for a queue cannot be obtained.
- Does SPINCOUNT also apply to queue semaphores?
- What is the timeout for the semop? Ie, how long does a process wait before reporting 1447?
3) Is there a similar (to Semaphore appears stuck) error for other semaphores, such as GTT, AOM, etc)?
- If yes, what is the timeout?
Thanks...
Roger

Roger,
1) The default SPINCOUNT value is 0 (no spinning) for all platforms that are supported today. (At one time we had a default value of 5000 for Sequent hardware, but it has been many years since we supported that platform.) The SPINCOUNT value that will work best for any application depends on many factors, including the number of CPUs on the machine, the hardware platform, and the indvidual application. SPINCOUNT will only be useful when the machine has more than one CPU.
2) /Q logs Q_CAT:1447 after 50 unsuccessful attempts to obtain the semaphore when the semaphore has never been released and reobtained by a different process or the same process during that period. The Access Control List code uses the same rule for logging LIBTUX_CAT:1511. If TMSPINCOUNT is set, then the number of unsuccessful attempts to obtain the semaphore is incremented by 1 only after TMSPINCOUNT spins have been done.
Code for the BB semaphore and the semaphore used by /Domain follows a different rule. This code will log LIBTUX_CAT:5005 or LIBGW_CAT:5010 if a process has to wait for the semaphore for 10 seconds and the semaphore has never been released by the original owner during this time period.
3) TMSPINCOUNT is used for the BB semapahore, AOM semaphore, ACL semaphore, /Domain semaphore, and /Q semaphore. Locking the GTT uses the same BB semaphore that used to lock other tables in the BB.
Regards,
Ed
