Data analysis means collecting the required data, check them and then store them. This process in done in many control systems like revenue collection in any municipality. In these control system many process of data documentation is done.They have to maintain the record of the transaction, collection, deposit and then process them.  It is also checked how much revenue is collected from government and how much is evaluated.

We need to assure the level of effectiveness in the control systems of government to deposit to the banks. Every respondent were asked to show their personal performance of their work. Every respondent have the knowledge of the accountable documents, revenue collection, deposition to the bank, andfinally to the revenue for custom.

Data summary:  every day banks takings are 23 which run at the same time. 28 runs sometimes and 4 never work. It means total work done is 55. Cash remitted in the bank at the same time is 27, 30 are done sometime, and 9 are never done.

It means the total work done is 66. Next is cash book and statements that are processed at the same time are 21, 16 are done sometimes and 4 are never done. It means total work done is 41. From the above data it can be said that overall work is done is 40%., this shows average internal controls of the bank. And after the complete study it is find that 67 respondents said that there were all the effective control exists all the time. And 70 said that there few internal work sometimes and 63 said there were no internal works.  These studies show that internal control in the account office is very weak.

If u wants to access the data using Jdbc then first you have to perform few operations to make the connection between the data base and programming environment. First we have to declare the parameters that will be used in the connection then we have to write the statements for making the connections and then execute those statements, then check whether it is generating exception any error or not. Then perform any query of you have then close the connection at last. Closing connection is important part otherwise no operation will be done in the data base.

We need a driver manager for connection any data base to our program. Every data base has its own driver. It is a standard class interface that is to configure the connection and make new connection every time.

If you are using SQL then you have to define the parameter used in the classes and RDBMS operation classes. After that you can use SQL query. SQL can be reused as it uses class called thread safe that encapsulate the query. Another class is stored procedure. This is also called super class. It is used to provide the data abstraction to the RDMS.

We also have SQL functions to perform RDMS operations. The default action is integer type but we can override it by making functions or methods, we might need extra parameter for that may be of return type. In SQL we use BLOB for storing the data of binary type and CLOB for storing the data of character type. If you want handle the large data then we can use springs. And it also provides high abstraction to the objects. We can also JDBC template with it.

Introduction to Cython Seminar Topic:

It is the advanced version of the programming language python, and it is also called the derivative of Pyrex language, designed with extra syntax and to remove the limitations of that language. They can also compile the code written in python, as they are first converted in to the c code. The generated c sometimes gives as error of declarations for the python and c types. To remove this we use Cython as it makes them in the part of the program.

These language first convert the code in to the following C/C++ code and then in the binary code. They the array very fast as they access the array of python directly as object and they support almost all types of number even complex floating type. They have faster functions and smart algorithm that are 6 times faster than the fastest. In C we have to call external function like sin () from math but in Cython it has its own sin () function that is faster than that. We need to import the c libraries from python and write the code also as fast as possible. In Cython we have different strings for both byte strings and Unicode strings.

Advantages: it has increased the speed of python almost to the speed of the C. it has added new data types and different types of declarations few static type. They are more than any wrapper solutions that are available.

Limitations: they face main problem during the compilation time. They have limited threading. They don’t have templates. Compiler sometimes ignores the error related to the static type declarations. They are the best when we talk about using the external libraries but it is not suited for replacing normal python code to Cython code. we require little experience while using dynamic and static block.

Introduction to Seminar Topic on Removable Media Storage Devices:

Mass storage or auxiliary storage refer to different devices are used to store huge amounts of data. Now many modern storage devises developed but in earliest days of early 1800’s only these storage devices developed. These modern storage devices includes all type of tape drives and disc drives such as optical disc drives, RAID systems, floppy disc drives, magnetic tape drives and drum memory.

These mass storage devices include non removable and removable media devices. Mass storage devices are similar to memory present in the devises but not the same. Temporary storage within system is referred as memory but mass storage devices store the data permanently even when the system turns off. These mass storage devices are measured in kilobytes (kb), megabytes (mb), gigabytes (gb) or in terabytes (tb) and these devices have characteristics of seek time, course capacity, transfer speed and cost.

Magnetic storage disks are mostly used in personal computers for storage media. This magnetic disk can be recorded and also re-recorded magnetically any times. Magnetic recording tapes, floppy disks, hard disks and magnetic strips on electronic cards are the common examples for magnetic storage devices. For creating CD’s and DVD’s optical storage devices are used that is written and read by light where the data is stored. Optical disks have the advantages of less weight and higher capacity over magnetic disks.Many mass storage devices are developed in advanced years day by day from when the first mass storage device floppy designed in 1971.

In this project we are going to give a detailed information that how mass storage devices store the data, types of mass storage devices, history of these mass storage devices and resent developments in these mass storage devices and what are the advantages of these mass storage devices.

Introduction to Schonhage Stassen Algorithm Seminar Topic:

This algorithm is used multiply the large integers quickly. The developers are Arnold Schönhage and Volker Stassen in 1971.This algorithm uses recursive Fast Fourier transforms in rings with 2²ⁿ + 1 element. There are several notations in this Big O notation. This algorithm was in use up to furers algorithm. But this algorithm achieves only astronomical large values. The method of schonhage-stassen is based on Crandall and Pomerance in their Prime Numbers.

Convolutions:

For example take numbers 123 and 456 and multiply with the base digit B without carry. The output is.

		1	2	3
	×	4	5	6
		6	12	18
	5	10	15
4	8	12
4	13	28	27	18

The sequence 4, 13, 28, 27, 18 is called linear convolution. They are original sequences of 1, 2, 3 and 4, 5, 6.

Convolution theorem:

The Stassen-schonhage algorithm depends on the convolution theorem. By the use of this algorithm two sequences can be easily calculated. Cyclic convolutions of two vectors are calculated by DFT discrete Fourier transform. Elements are multiplied vector by vector.

CyclicConvolution(X, Y) = IDFT (DFT(X) · DFT(Y)).

For the multiplication of algorithm and to invoke recursively if we use DFT and IDFT for the vectors DFT(x) and IDFT(y) this results in a best algorithm for cyclic convolutions.

Nega cyclic convolution is very useful if use in this algorithm it’s a update of convolution theorem. It can be stated as

A = (a^j), 0 ≤ j<n

A⁻¹ = (a^−j), 0 ≤ j < n

Now, we can state:

NegacyclicConvolution(X, Y) = A⁻¹ · IDFT (DFT (A · X) · DFT (A · Y)). 

The multiplications of recursive vectors element-by-element can easily calculated by nega cyclic convolution. It also faster than cyclic convolution theorem because it has slight modification mod 2ⁿ + 1.

Introduction to Attacking LSB Based Image Steganographic Technique Seminar Topic:

The word stegano was derived from a Greek word called steganos which means covering or hiding. Steganography means hiding important messages in any form image, audio, video, paper etc. The process allows covering important messages in uncommon way. From the ancient days steganography was used by covering the wood texts with waxes. During the World War 2 also it is used by some spies. Invisible inks are mostly used as a process of steganography they are seen only heated under fire. Steganography is used ide copy-right information in images or audio or video. By this third party sharing.

Steganography-Today:

Us government concerned the needs of the steganography. Terrorists are using steganography to communicate between each other.

Introduction to Seminar Topic on Static Router:

Router is a device which routers the inter network from the source to destination. They transfer the packets from one network to another network. Routers use static and dynamic routing protocols in certain situations. Static routings are very common in routing.

Role of Router:

Routers are plays a key role in internet working. They determine the best path to transfer the packets from the source to the destination. It includes forwarding the packets or sending. They perform routing by remote networks and maintaining information about packets. The routers first forwarding decision is based on three layer information that is internet proxy address. The routing table is best way to find the match between the destination internet proxy of a packet and network addressing routing table. The router encapsulates the packet and sent them to appropriate IP address.

Router connections:

The router is to be connected with network with router interface. There are different types of connectors.

Serial connectors:

In serial connectors support EIA/TIA-232, EIA/TIA-449, V.35, X.21, and EIA/TIA-530 standards of connectors.DB-60 port supports five different cables and other ends are connected supported cables. Routers support smart serial interfaces which are 26-pin connectors it is whether DCE or DTE configuration type. It is smaller compared to DB-60. The cable which that we are using that is automatically determined by WAN-service that we are using.

Ethernet Connectors:

In Ethernet connectors a twisted pair RJ-45 connector is used for LAN-connections. It has eight-colored pins or strips. Ethernet cable uses 1, 2, 3 and 6 for sending and receiving data. A patch cable and cross over cables are used to connect.

Straight-through cables are used for:

• Switch-to-router
• Switch-to-PC
• Hub-to-PC
• Hub-to-server 

Crossover cables are used for:

• Switch-to-switch
• PC-to-PC
• Switch-to-hub
• Hub-to-hub
• Router-to-router

Introduction to Honeypots For Network Security Seminar Topic:

             Honeypots, an exciting new technology allow us to turn the tables on the bad guys. There has been a growing demand and interest in the field of honeypot technology.

           A honeypot is used in the field of network security. It acts as bait for potential attackers; the honeypot in turn gathers as much data on the attacker as possible to help determine their identity. A major goal of this paper is to showcase the possibilities of honeypots and their use in a research and productive environment.

A honeypot is much better at discovering suspicious intruders than an intrusion detection system. Honeypots have a big advantage where they do not generate false traffic reports, so it is harder for intruders to detect the device.

Introduction:

             As global communication is increasing in importance every day, so are computer crimes. Counter measure have been developed to detect and prevent intrusions by analyzing known facts and attack patterns. Similar to the military where it is imperative to know your enemy and their strategies and tools, computer security experts also need to know what their intruders are doing, what tools they are using and where they are based. If one knows this information, counter strategies can become more efficient and optimized. And one of the main goals of Honeypot is to gather this data.

A honeypot is principally a device which gathers information to learn from it. Its primary purpose is to camouflage itself from the black hat community so that they can be caught red handed. The honeypot silently gathers information like, their attack patterns, programs used, as well as information about the black hat community itself. There are other ways in which a honeypot helps intrusion detection. A honeypot can detect intruders while they are performing an attack and gather information about them.

                Although honey pots are good at preventing intrusions, they are not a perfect solution for preventing computer crime. They are hard to maintain and administrators need good knowledge about operating systems and network security. In the correct hands, a honeypot wields immense power to root out crime from the black hat community, but in the wrong hands, it becomes an instrument which is leveraged by the black hat community to commit crimes.

While this storage want is being met the storage technologies should continue so as to stay pace with a quickly increasing demand. With the decreasing price of storing knowledge and increasing storage capability with a same little device foot print are key enablers of this revolution.

Storing info through the amount of the medium not on its surface offers associate intriguing high capability various. Holographic knowledge storage could be a meter approach that has created recent progress towards utility with the looks of lower price facultative technologies.

With its ubiquitous laptop all connected via net modern era has lead associate explosion of data out there to users. Therefore the holographic memory has become a good Delphinapterus Lucas of technology analysis.

Concept of Holographic Memory

In optics, the intent is to record total wave field (both amplitude and phase) because it is intercepted by copy medium the record in plane might not even be a picture plane. The scattered or mirrored light-weight by object is intercepted by the recording medium and recorded utterly in spite of the actual fact that the detector is insensitive to the section distinction among the assorted a part of the optical field.

In optics, interference between the article wave and reference wave is made and recorded on a holographic material. The record referred to as exposure (whole record) captures the entire wave which may be viewed at the later time by illuminating the exposure with associate acceptable light. to the current day optics continues to supply the foremost correct depiction of three-D image within the world.
