Data Warehouse Seminar topic explains about the data warehouse testing. And for every organization which is implementing the data warehouse, testing to be done effectively so that success is achieved and also the risks are reduced.

The people in the IT field even believe in the saying of “trust, but even verify”. We can even say that there are drawbacks even in the process of testing. In general testing is performed by writing the test cases and they assume that test is passed even when a single test condition is met. But it is not true in case of the production phase. In some situations some of the requirements are not even met.

Also in the business some rules even appears to be false and also complex to implement when compared to that of the original situation the applications of the data warehousing changes with the change in the requirements.

In general the data warehousing is a repository of the data which is capable of maintaining the historical data. With this history a decision can be made based and also analysed. We can even say that if the bug is identified in the later stages of the testing process then it can also result in much financial losses so efforts are needed to identify the bugs at the initial stage.

So the data warehousing testing is considered as the best practise so that top position can be achieved in the business. The testing procedure can involve in various phases so that the business is done in an efficient way. We can conclude that for every organization which is implementing the data warehouse, testing to be done effectively so that success is achieved and also the risks can be reduced.

Introduction to  CSE PPT Topic on Analysis of the Algorithm:

This Analysis of the Algorithm Paper Presentation is about the analysis of the algorithm. An algorithm is defined as set of instructions which are written for solving a problem. 

In case of any computing problem there is a need for improving the efficiency of the algorithm so that more data can be processed and also the execution can be done faster. The algorithm is more useful in situation where the complexity in the problem. In order to reduce the execution times where there are a large number of instructions. The algorithmic approach provides a simple and clear solution to the problem

The analysis of the problem is done so that the resources which are needed are known beforehand. The resources can be related to the computational time, can be the memory and also the bandwidth of the communication.

In some algorithms security can be even provided using the cryptographic functions so that the security is attained by the process of encryption and also decryption. The data is encrypted so that the data is hidden and not exposed for ensuring the security and then decrypted once the data is delivered to the destination.

Hash tables are used for searching the data in the data structures. It involves various operations related to the insertion, also deletion and also the updating of the data. In the analysis of the algorithm the worst case is used to providing the upper bound during the execution time. The best case involves the input where the algorithm executes in a faster way. In the average case it is used for predicting the execution time.

We can conclude that the algorithmic approach provides a simple and clear solution to the problem.

Introduction to Paper Presentation Topic on Analysis of Algorithms:

Analysis of Algorithms Paper Presentation covers detail information regarding the algorithm. An algorithm is defined as set of instructions which are written for solving a problem. The set of values are provided as input and as output we can expect a value or a set of values.

The algorithm which is set of instructions can be written in simple language like English, or can be provided as a computer program or even can be implemented as a pseudo-code.  The data structures can be used for the organizing the data.

When we discuss about the reasons for developing an algorithm it can be due to many reasons like reducing the complexity in case of a typical program, reducing the execution time in case of large number of instructions. The algorithmic approach provides a simple and clear solution to the problem.

We perform analysis on only the correct algorithms. These algorithms if we provide the correct input instance then they result in correct output.  When we analyse any problem we can know the resources which are needed in beforehand. The resources can be related to the computational time, can be the memory and also the bandwidth of the communication.

The analysis of the algorithms can depend on several factors related to the algorithm or can vary based on input values and even the compiler. The main question is how to measure the efficiency of the algorithm. In this paper we have provided the solution as number of operations that are performed by the algorithm.

We can conclude that algorithm is defined as set of instructions which are written for solving a problem. The algorithmic approach provides a simple and clear solution to the problem.

Introduction to CSE PPT Topic on Analysis Model:

Analysis Model Paper Presentation explains about the analysis model. The main objectives of this model are for describing the requirements of the customer, creation of a software design and also the set of requirements for validating when the software is developed.

To perform the analysis we build a model so that the system can be understood in a better way. Also when the systems are complex we build models so that complexity reduces. The aim of the analysis is for providing visualization of the system; it is used for documenting the decisions and also involves the specification of the structure of the system.

The model is capable of relating among the data objects. The focus is mainly on the data domain. Processing of the data objects is done independently. The entity relationship model is used for the giving the relationship between the entities or objects. It is the simplest way of the representation of the model.

The entity relation model consists of various objects or entities. The relationship between the objects is represented using the arrows and the relationship gives the cardinality relation between the objects.

The feature of the object oriented approach can be attained using various models related to the aggregation and also the models related to inheritance. In the model of the inheritance the object classes are organised into the hierarchy. All the features of the classes which are common are placed at the top of the hierarchy. One object is capable of inheriting the attributes and also services from one class to other class. 

Whereas when we consider the aggregation model, the aggregation model is used for denoting the classes which are composed from other classes.

We can conclude that analysis model is used for describing the requirements of the customer, creation of a software design and also the set of requirements for validating when the software is developed.

Introduction to Privacy and Anonymous Communication Presentation:

Privacy and Anonymous Communication presentation is about the anonymous communication. This paper includes various concepts related to the privacy and also the analysis of the traffic, the communication which is anonymous, also the onion routing and also the attacks on anonymity.

The property of privacy includes the protecting of the information so that the unauthorized users will not have access to the information. Whereas the traffic analysis includes the intercepting and also the examining of the messages so that information is obtained from the patterns of communication. Also the analysis includes the information about the size and also the frequency of the transfer of the data.

The property of the anonymous communication involves ensuring the security communication between two parties so that the third party is not capable of knowing the information. The implementation of this type of communication is done using several methods like Broadcast and also using proxy.

The onion routing mechanism is implementation of the anonymous communication in a computer network. For ensuring the security the messages which are to be sent are encrypted and then sent over the network with the help of the networking nodes named as the onion routers. The main goal of its implementation is ensuring the security so that the privacy exists of the sender and also the receiver of the message.

We can conclude that anonymous communication involves ensuring the security communication between two parties so that the third party is not capable of knowing the information. The implementation of this type of communication is done using several methods like Broadcast and also using proxy.

The paper is about the Bluetooth. In this project we have described about the Bluetooth, its goal, also includes the brief history of it. This paper also includes various modules and also the real time applications of Bluetooth. 

In this paper, we use Bluetooth for the sensor network regime. We will discuss a multihop network procedure that leverages Bluetooth’s device protocol, and also discuss the way the Bluetooth plays a vital role in-network query processing.

The results show that despite of limitations the Bluetooth sensor nodes exhibits properties such as energy per bit sent ratio. 

There are two types of radio components for sensor nodes: those based on fixed frequency carriers and those based on spread-spectrum transmissions such as Bluetooth, the sensor nodes within a certain range make use of the separate channels so that the data is transmitted. 

Our results says that Bluetooth based sensor networks are well suited for applications such as mounted operations which exchanges data heavily during a period of time.

Our experiments with the BTnodes suggest that Bluetooth based sensor nodes could be appropriate for applications exchanging huge amount of data during a limited time period.

Bluetooth Technology Seminar Report

Bluetooth is considered as the best device for communications because of the following features i.e. interoperability can either exhibit between the devices or can be between the manufacturers. The implementation of the Bluetooth is easy i.e. it is self operatable without a need of the user’s guide.

It is comparatively less or similar to that of cost of the cable it is getting replaced. It is capable of performing its task at lower power consumption.

Introduction to An Efficient Architecture for 2-D Lifting-based discrete Wavelet Transform Presentation:

This CSE PPT topic is about an efficient VLSI architecture for implementing the 2-D discrete wavelet transform. The number of applications based on integrated circuits resulted in high performance computing, telecommunications, and consumer electronics has been increasing. In this paper we discuss about VLSI, the whole architecture is designed in such a way that there is an increase in the speed and also the utilization of hardware is done efficiently.

One of the most important characteristics of for today’s services focusses on the higher bandwidth and also high processing power. The other characteristic which is focussed more is the personalized services to the user depending on the user requirement which includes the flexibility also the mobility feature.

When we consider VLSI design styles, several design styles can be considered for chip implementation of specified algorithms. Each design style has its own advantages as well as disadvantages and thus an appropriate choice has to be made by designers in order to provide the functionality at low cost. It includes Field Programmable Gate Array an array of logic cells connected via routing channels. These cells include Special I/O cells and logic cells. When we consider that other design style which comes after FPGA is Gate Array, which is capable of processing fast. The implementation includes with the metal mask design and also processing.

The GA chip utilization factor is higher when compared to that of FPGA and in terms of speed also it is higher. One of the most custom design styles is Semi-Custom design style. All the used logic cells are developed and characterized and stored in cell library. When we consider the full custom design, the mask design implemented without the usage of the library.

We can conclude that the 2-DWT is used in many applications related to the image compression techniques.

Introduction to Amorphous Computing and Swarm Intelligence Seminar Topic: 

Amorphous Computing and Swarm Intelligence seminar topic is about the amorphous computing. The amorphous computing includes interacting computers with the power of the computing and also the memory, and also includes modules for the inter communication. The devices collections are named as swarms.

 The global behavior of the computer system is achieved with the help of the local interactions using the individual agents. The behavior of the unreliable agents also results in the misbehaving agents and also as a noisy environment. 

The idea of the amorphous computing is from the swarm behavior of the social organisms like ants. This intelligence of the swarm is derived from the features of the randomness; the repulsion feature and also unpredictability feature of the agents so that it provides different solutions for the problems. 

The main objective of the computing involves the algorithm creation and also the creation of the technique for meeting the programming requirements. An amorphous computing system is a system which is placed irregularly and also not synchronous and also interacting systems which is done locally. 

The advantages with the implementation of the system, includes the decentralization of the control i.e. the global information is not available in the system. The agents are capable of reacting to the change in the environments. It does not require any interaction with the direct agent. Agents are not goal oriented. 

There exist some disadvantages with the system i.e. implementation of the swarm-based system is typical. Also the behavior of the individual system implies a noise and also parameter has tremendous effect on the behavior. 

We can conclude that the amorphous computing includes interacting computers with the power of the computing and also the memory, and also includes modules for the inter communication.
