Explain the weaknesses of the OOA/OOD focusing only on Use-cases and Class Diagram Design using CRC cards without using State Diagrams.
Solution
Object-oriented analysis (OOA) and design (OOD) are techniques which have evolved since 1988 to support the creation of object-oriented software targeted at languages like Smalltalk, C++ and Eiffel.
A contrast is drawn between the older structured systems analysis and design and the newer OOA&D. The aims and goals of SSA&D are different from the aims and goals of OOA&D.
A large number of OO methods for analysis and design have been put forward. These can roughly be categorised as:
relationship and attribute centred approaches (Shlaer/Mellor, Coad/Yourdon)
behaviour centred approaches (OBA, RDD)
high industrial profile approaches (OMT, Booch)
synthesized approaches (Objectory, Fusion)
No one approach has all the best techniques
Very few approaches cover all aspects in equal depth
Complexity and Abstraction
A look at the psychology behind human conceptual activity.
Complexity
Software is among the most complex of human artefacts.
few material constraints, contrast bridge designs;
arbitrary reconstructions, contrast building designs;
Abstraction
Abstraction is the tool we use to encapsulate complexity:
higher abstractions introduced to reduce complexity;
certain aspects of problem highlighted;
certain aspects of problem suppressed.

Diagrammatic knowledge modeling for managers – ontology-based approachDmitry Kudryavtsev
Diagrams are an effective and popular tool for visual knowledge structuring. Managers also often use them to acquire and transfer business knowledge. There are many currently available diagrams or visual modeling languages for managerial needs, unfortunately the choice between them is frequently error-prone and inconsistent. This situation raises the next questions. What diagrams/ visual modeling languages are the most suitable for the specific type of business content? What domain-specific diagrams are the most suitable for the visualization of the particular elements of organizational ontology? In order to provide the answers, the paper suggests light-weight specification of diagrams and knowledge content types, which is based on the competency questions and ontology design patterns. The proposed approach provides the classification of qualitative business diagrams.

Astronomy 107- 1- Why does helium fusion require a higher temperature.docxjames876543264
Astronomy 107:
1. Why does helium fusion require a higher temperature than hydrogen fusion?
2. What is degenerate matter? Why is it so difficult to compress?
3. Why can’t a white dwarf continue to contract as it cools? What is its fate?
4. How can a star with as much as eight solar masses form a white dwarf when it dies? (Hint: A white dwarf can be no more massive than 1.4 solar masses.)
5. How does the inward collapse of a massive star produce an outward explosion?
6. Distinguish between a Type I and a Type II supernova.
7. What is the approximate density of a white dwarf? A neutron star? Why can the neutron star be a few miles in diameter, while a white dwarf is roughly the size of earth?
8. What is the last nuclei that appear in massive star’s core? Why is it the last?
Solution
1.
helium fusion require higher temperature to overcome the greater repulsive force between the protons in helium. the repulsive force is greater because helium has two protons while the hydrogen has only one proton. at higher temperature , the protons collide efficiently and can get close enough to fuse together.

Astronomers have found “dark matter” in a variety of environments. Name the places where dark matter has been found, and briefly describe how the discovery was made in each case. The question is: In what way is this similar to the construction of Hubble’s law?
Solution
The matter that we cannot observe directly \"dark matter,\". Many evidence are found shows that super massive black hole (dark matter) is located at the galactic centre.
The large fraction of invisible matter is present in the universe because gravity produced by all luminous body is very less compared to amount of gravity required for the stars to orbit around galaxies and the galaxies to their galactic centre.
According to Hubble\'s law all objects appear to be farther away from us.This is possible if the expansion of the universe is accelerating , not decelerating. In order for the universe to accelerate, there must be some force pushing all of the galaxies away from each other, and this force must be strong enough to counteract the deceleration by gravity.

As we know- total ownership is not a requirement for consolidation- A.docxjames876543264
As we know, total ownership is not a requirement for consolidation. A parent need only gain control of another company to create a business combination. If less than 100% of a subsidiary\'s voting stock is obtained, how is the presence of the other owners reflected in consolidated financial statements? What accounting is appropriate for a noncontrolling interest? How are these figures computed and where are they reported on the consolidated statements?
Solution
When a parent acquires more than 50% but less than 100% of the voting stock of a subsidiary company, it is said to have controlling interest in that company. The remaining portion which is not acquired by the parent company is called non-controlling interest or minority interest. These are other owners whose interests are seperately reflected in the parent company\'s financial statements (balance sheet as non-controlling/minority interest).
Non-controlling interest is reported on the liabilities and stockholder\'s equity side of the balance sheet of the parent company under the head \"Equity\". It is important to note, that minority interest is recorded independently of the equity of the parent company.
Consolidated net income of the parent company and subsidiary company must be shown seperately for the parent company and minority interest in the consolidated income statement. In a similar way, the comprehensive income is also allocated between the controlling and non-controlling interest.

Asset Depreciation
2 2 unread replies. 2 2 replies.
Answer each of the following questions
What is the rationale for depreciating assets used in business? Do you agree with it?
Does the rationale have any implications on capital formation
Solution
1 ) Rationale for depreciating assets is that the depletion in the value of assets over the period of time due to the wear and tear of the asset . It is said to be the cost of assets allocated in the financial year according to the benefits generated by the use of the asset
2) Depreciation is a non cash expense and we traet as a expense that results in decline of profits due to which there is an accumulation of funds in the company and therefore helps in capital formation
3) Rules regarding depreciation are same for all the tax payers hence it does not favour any single group of taxpayers
4)Revenue implications : The method of depreciation adopted by the company can impact revenues . Depreciation amount will be different by any method

As a transportation planner-engineer- would you implement a bus servic.docxjames876543264
As a transportation planner/engineer, would you implement a bus service or a light rail service in a Completely Motorized Network Urban Structure? Provide 3 reasons for your choice.
Solution
As a transportation planner I want to improve bus service(BRT)
modern communication systems, smartcard ticketing, GPS, intelligent transport technologies and computer optimisation techniques it has become possible to serve urban transport needs with modern bus rapid transit (or high capacity bus systems) very adequately. These bus systems have the following advantages:
i) Bus rapid transit (BRT) systems can serve the needs of medium sized cities all the way up to mega cities.
ii) BRT systems can easily reach capacities of 20,000 passengers per direction per hour. These capacities are very adequate for cities which have multiple business districts and medium rise buildings. In such cities higher
capacity systems will never run at peak capacity.
iii) BRT can be implemented at a fraction of the costs involved in building metro rail transit and light rail systems. BRT systems use existing right-of-way on urban corridors and so the modifications involved do not disrupt the city significantly.
iv) A major advantage of BRT is its flexibility in meeting changes in the city development and in changes in demand in quality and quantity.
V)Rail systems can only serve a very limited area of a city. Not one developing country city subway system serves more than 10% of population. BRT systems can achieve very high coverage at low investment costs.

explain why glass electrode is a good example of an ion selective elec.docxjames876543264
explain why glass electrode is a good example of an ion selective electrode
Solution
Glass membranes are made from an ion-exchange type of glass (silicate or chalcogenide). This type of ISE has good selectivity, but only for several single-charged cations; mainly H + , Na + , and Ag + . Chalcogenide glass also has selectivity for double-charged metal ions, such as Pb 2+ , and Cd 2+ . The glass membrane has excellent chemical durability and can work in very aggressive media. A very common example of this type of electrode is the pH glass electrode.
An ion-selective electrode ( ISE ), also known as a specific ion electrode ( SIE ), is a transducer (or sensor) that converts the activity of a specific ion dissolved in a solution into an electrical potential. The voltage is theoretically dependent on the logarithm of the ionic activity, according to the Nernst equation. Ion-selective electrodes are used in analytical chemistry and biochemical/biophysical research, where measurements of ionic concentration in an aqueous solution are required.
A glass electrode is a type of ion-selective electrode made of a doped glass membrane that is sensitive to a specific ion. The most common application of ion-selective glass electrodes is for the measurement of pH. The pH electrode is an example of a glass electrode that is sensitive to hydrogen ions. Glass electrodes play an important part in the instrumentation for chemical analysis and physico-chemical studies. The voltage of the glass electrode, relative to some reference value, is sensitive to changes in the activity of certain type of ions.

Explain why in the DPCM structure- the input to the predictor P is the.docxjames876543264
Explain why in the DPCM structure, the input to the predictor P is the quantized version of the original input [n] instead of the actual original input x[n]. [please i need a detailed explanation]
Solution
we go for using DPCM instead of PCM system inorder to decrease the QUANTIZATION ERROR ....we know for multiplexing point of view channel bandwidth should be as high as possible and the signal bandwidth is as low as possible for more number of signals to be transmitted via the same channel ...in PCM system direct input is applied to sampler after encoder block and sampled values are given to quantizer those quantized values are given to decoder via regenerative repeaters and then to the receiver at the receiver input we have probability of error because of quantization distortion called the quantization error ( Q e )
quantization error varies between -(delta)/2 to +(delta)/2
here delta is called the step size
delta= (signal amplitude (peak to peak)) /2 n and band width in PCM = 1/T b
where as T b = T S /n
as signal ammplitude increases quantization error increases ,
so for decresing the Q e either the value of n is increased or the signal amplitude should bd decreased
if we increase n value the bandwidth of a signal will increases multiplexing point of view which is a drawback
so we go for DPCM system in which we are applying difference amplitude
means difference of present sample value - previous sample value so numerator of step size decreases
the Qe value also decreases so for reducing of quantization error we are using DPCM insted of PCM

Solution
Answer:
The Westminster System is a democratic system of government modelled after that of the United Kingdom, as used in the Palace of Westminster, the location of the UK parliament. The system is a series of conventions and procedures for operating a legislature. It is used, or was once also used, in most Commonwealth and ex-Commonwealth nations. There are other parliamentary systems, for example those of various European countries, whose procedures differ considerably from the Westminster system.
Aspects of the Westminster system include:
Most of the procedures of the Westminster system originated with the conventions, practices and precedents of the UK parliament, which are a part of what is known as the British constitution. Unlike the UK, most countries which use the Westminster system have codified the system in a written constitution.

Explain what an
Solution
An intervention is a deliberate process by which change is introduced into peoples thoughts, feelings and behaviors. The overall objective of an intervention is to confront a person in a non-threatening way and allow them to see their self-destructive behavior, and how it affects themselves, family and friends. It usually involves several people who have prepared themselves to talk to a person who has been engaging in some sort of self-destructive behavior. In a clear and respectful way, they inform the person of factual information regarding his or her behavior and how it may have affected them. The immediate objective of an intervention is for the self-destructive person to listen and to accept help.
Intervention can be used in various settings depending on the need of the organization.
Survey feedback intervention provides data and information to all the managers. Information related to the attitude, structure, working conditions will be included in the survey. Managers analyze the data pertaining to each and every employee and takes appropriate action. They try to analyze the problem, evaluate the result and correct the problem.
Key considerations include:
1) involvement of organizational decision makers,
2) development of a situation change model, and
3) use of evaluative methods and measures that corroborate evidence of outcomes.

Explain what is meant by the statement that a preferred stock is a hyb.docxjames876543264
Explain what is meant by the statement that a preferred stock is a hybrid between a common stock and a bond. What factors determine the value of a share of preferred stock?
Solution
Preferred stock is featured as its name that is preference . Preferred stock is always given preference over common stock that is they are the first one to claim their right on the income of the company either at the time of distribution of income or at the time of the liquidation of the company , this is the main difference between the preferred stock and the common stock . Preferred stock is also considered as a type of bond due to its feature of fixed income and repay characteristic at the time of maturity these are the reason ehy the preferred stock is considered as a hybrid between common stock and a bond
Factors determining valuation of preferred stock
1) Fixed dividend: Holders of preferred stock treat it as a investment that gives them fixed income in the form of dividend like bond gives fixed interest
2) Market interest rates: Preferred stocks are also a type of bond hence market interest rates plays a important role in the valuation of preferred stock , if market interest rate is down then preference rate increases and it the market interest rate is high then the preference rate goes down
3) Structure: Whether the preferred stock is convertible or non convertible also plays a great role in the valuation of the preferred sock

Explain two Principle of locality used in Memory Hierarchy-SolutionHie.docxjames876543264
Explain two Principle of locality used in Memory Hierarchy.
Solution
Hierarchical memory is a hardware optimization that takes the benefits of spatial and temporal locality and can be used on several levels of the memory hierarchy. Paging obviously benefits from temporal and spatial locality. A cache is a simple example of exploiting temporal locality, because it is a specially designed, faster but smaller memory area, generally used to keep recently referenced data and data near recently referenced data, which can lead to potential performance increases.
Principle of Locality: Memory Hierarchies :-
Temporal locality- Recently accessed items will be accessed in the near future.
Temporal locality is found in instruction loops, data stacks and variable accesses. If at one point a particular memory location is referenced, then it is likely that the same location will be referenced again in the near future. There is a temporal proximity between the adjacent references to the same memory location. In this case it is common to make efforts to store a copy of the referenced data in special memory storage, which can be accessed faster. Temporal locality is a special case of spatial locality, namely when the prospective location is identical to the present location.
Spatial locality - Items at addresses close to the addresses of recently accessed items will be accessed in the near future.
Spatial locality describes the characteristic that programs access a number of distinct regions. If a particular storage location is referenced at a particular time, then it is likely that nearby memory locations will be referenced in the near future. In this case it is common to attempt to guess the size and shape of the area around the current reference for which it is worthwhile to prepare faster access

Explain the use of directives in configuration files- Provide an examp.docxjames876543264
Explain the use of “directives” in configuration files. Provide an example of two directives found in an Apache configuration file and detail what each accomplishes.
Solution
The configuration files contain directives that can be applied to the entire server, or they may be restricted to apply only to particular directories, files, hosts, or URLs.
HTTP Server of Apache is configured by putting or placing directives in plain text configuration files. Configuration file httpd.conf is called main configuration file. During compile time its location is set, but command line flag -f is used if it\'s need to be overridden ever.Directive \"Include\" is used to add other configuration files ,likewise wildcards can also be used to add many configuration files.Any of these configuration files can be used to place any of the directives,httpd is used to recognised if any of the changes is made in main configuration file when it is started or restarted. The <If Define>directive encloses directives that will only be applied if an appropriate parameter is defined on the httpdcommand line.
The < IfModule>directive is very similar, except it encloses directives that will only be applied if a particular module is available in the server. The module must either be statically compiled in the server, or it must be dynamically compiled and its LoadModule line must be earlier in the configuration file. This directive should only be used if you need your configuration file to work whether or not certain modules are installed. It should not be used to enclose directives that you want to work all the time, because it can suppress useful error messages about missing modules.

Explain the motivation behind using a header file for a C program-Solu.docxjames876543264
Explain the motivation behind using a header file for a C program.
Solution
Motivation behind using header file in c Programming:
Header files contain definitions of functions and variables which can be included into any c program by using #include.
Compilation speed up and optimization :During compilation of some parts of the code it may be sufficient to load API interfaces from header files to check correctness of the code used while defining them.
-2. The motivation for the introduction of header files is type safety. C allows function calls without forward declaration. Logically speaking using functions without forward declaration is as harmful as using Macros as compilers has no proper mechanism to validate the type of the arguments with the parameters. So chances of unresolved linkage errors and runtime failure is more prominent.
3. Header files are more like data abstraction, you just see the important components and you don\'t need to know the background process.
4. To reduce overhead of RAM....the functions or classes defined in these header files are already compiled so they can be directly used .
5.Including a header allows your code to call functions or methods which are written elsewhere and which may or may not be a part of your software project/build, but which can be found by the \'linker\' when you are building the software.
6. Header files are mainly used to declare and include the signatures (i.e. function name, return value and arguments) of your functions in other files. The compiler needs to know these signatures when compiling and linking your files together.

Explain the importance of using the typedef keyword then write a C ++ statements (examples) showing how it works for declaring a string data type.
Solution
typedef is a reserved keyword in the C and C++ programming languages. It is used to create an alias name for any other data type. As such, it is often used to simplify the syntax of declaring complex data structures consisting of struct and union types, but is just as common in providing specific descriptive type names for integer data types of varying lengths. [1] They are most often used when a standard declaration is cumbersome, potentially confusing, or likely to vary from one implementation to another
The typedef keyword allows the programmer to create new names for types such as int or, more commonly in C++, templated types--it literally stands for \"type definition\". Typedefs can be used both to provide more clarity to your code and to make it easier to make changes to the underlying data types that you use.
the following declarations define a new data type with the name string:

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Explain the weaknesses of the OOA-OOD focusing only on Use-cases and C.docx
1. Explain the weaknesses of the OOA/OOD focusing only on Use-cases and Class Diagram
Design using CRC cards without using State Diagrams.
Solution
Object-oriented analysis (OOA) and design (OOD) are techniques which have evolved since
1988 to support the creation of object-oriented software targeted at languages like Smalltalk,
C++ and Eiffel.
A contrast is drawn between the older structured systems analysis and design and the newer
OOA&D. The aims and goals of SSA&D are different from the aims and goals of OOA&D.
A large number of OO methods for analysis and design have been put forward. These can
roughly be categorised as:
relationship and attribute centred approaches (Shlaer/Mellor, Coad/Yourdon)
behaviour centred approaches (OBA, RDD)
high industrial profile approaches (OMT, Booch)
synthesized approaches (Objectory, Fusion)
No one approach has all the best techniques
Very few approaches cover all aspects in equal depth
Complexity and Abstraction
A look at the psychology behind human conceptual activity.
Complexity
Software is among the most complex of human artefacts.
few material constraints, contrast bridge designs;
2. arbitrary reconstructions, contrast building designs;
Abstraction
Abstraction is the tool we use to encapsulate complexity:
higher abstractions introduced to reduce complexity;
certain aspects of problem highlighted;
certain aspects of problem suppressed.
