Introduction to Night Vision Device Seminar Topic:

Now since we have deeper understanding regarding area and the use of NVD after reading previous article letter some of deeper concept .On how this things work. A quick recall on what exactly is Night Vision Device (NVD) .We saw how it was used for military purpose,

How it was used for when applying the concept of thermal imaging, then how physics was applied while creating NVD .Let’s take a case study of US military to know about Night Vision Device. Some of the well known NVD device used is AN/PVS-14 which used by US citizen and its military .The thermal imaging technique we have discussed works on infrared technology. 

Now let’s see how the US military advanced after using generation 3 NVD.One of technology Panoramic Night Vision Goggles was tested on the basis of NVD. A nice example of PNVG.

PNVG stands Panoramic Night Vision Goggles.

Generally seen in the aircraft system which require information such as altitude, speed of plane in air this all are integrated into aircraft system based on the concept of NVD.

See this figure you must have seen in lot of Hollywood Bollywood movies a person wearing such type of helmet during border fight.

I stand for Integrated which means one can see from his naked eye as well as from the system generated eye. System generated eye means it captures the images of surrounding with use of NVD that helps to easily capture even at night. The color on the entire NVD device is that they produce green light.

Introduction to Night Vision Device Technology Seminar Topic:

Night Vision Device is nice topic of great interest of youngsters of modern time of enthusiastic about the improvement in science.

So before knowing the advantage of using Night vision device, we should know the prime reason for creating such a device .Actually this was originally developed for military. Since it was difficult to know what the enemies are up to once the night occurs. It is well known fact that humans cannot see in dark where there is no light .With this form of device we can see a person who is 180-200 m away from us. 

We have two types of night vision

1. Biological Vision      2.Technical Vision 

With every generation i.e first generation ,second  generation and so on ,the way the device purpose was same but the way of working and situation might vary .We might have observed this technology while playing action games. Our main character wore the night vision device and the screen observed by us would be green. So now you might think it be just about creating a story more interesting they might have done so ,but the truth is there is a science behind it .So why do Night Vision Device have images shown in green .The reason is simple Night Vision Device ( NVD ) use green because it is more defined image. 

One more scientific fact is that apart from other color such red, blue so on human have the ability to differentiate different shades of green. The second generation of this device made better use of thermal imagining.

So what exactly is Thermal Imagining .This is a technique that allowed the NVD to work even in foggy, smoky, dusty condition.

Eg .This form of situation generally prevails in desert.

Introduction to peed Detection of Moving Vehicle Using Speed Cameras Seminar Topic:

Lets try to examine the title of our topic taken; here we find five main keywords

1 .speed

2 .detection

3.vehicle

4.camera

5.moving speed 

So why exactly is need to develop such a system is the next question that comes in our mind,it is because , since we see in our daily life as population increases we see that the number of vehicle has also increases .Due to increase the number of vehicle there has been a number of traffic problem that arises ,thus this was the reason to create a speed detection of vehicle. So how exactly is the speed being detected is the next question that comes in our mind? One of the best techniques is used sensor, as with sensor we would be able to detect the system. 

Now let focus on the method used to make such a system:

An image taken of traffic cannot be best possible solution Keeping the importance of time factor in time as it is crucial point of traffic when managing; we will decide this factor for our speed detection .Speed detection is done on the time lag between two images. Thus it means at interval of particular time multiple images are taken out as then using special algorithm the movement of machine is compared. 

What if we are unable to achieve the speed detection, just think of the number of accident that is going to happen .We may not know what the possible cause of that accident was? A simple eg of such an aerial view is seen in Google Map. This type of system is generally need to be implemented for traffic management in metro areas

Introduction to An ATM with eye Seminar Topic:

There was a time when we do not pay importance to time, later we felt importance of time, later we felt unsatisfactory result even with span of time. This statement stands true for the topic we are learning. ATM it stands for Automated Teller Machine. 

Thus to fulfill the above goal i.e customer satisfaction, time saving of customers ATM was created. ATM is generally used for money transaction. Now since we already know what is money and how transaction of money is we are going to skip this .Lets look on how the ATM works. The most important security of ATM is pin that is used.  ATM is a machine, in order to access the machine and get some money some form of magnetic card is used .This would decrease fraudent activity. 

Since this is a system that is going to be used by a lot of people there is need to maintain some form of privacy. Why exactly a privacy is needed is the next big question that comes in the mind ?Its because we are sharing the Automated Teller Machine to perform same task i.e taking money using different account number .To properly use the ATM we need to give the account number to the system ,which is followed by Pin. 

We generally see a bank as one of the main reason that is responsible for the growth of ATM. Now one of the one question that may come in our mind is why only pin for authentication, why not something else say images for detection. Since images stored in database may not perfectly match one face even if its face of correct person who gave the image, the pin used for authentication seems to be the smart choice. Again speaking on one of the concern related to customers is privacy of images in bank database since it may be misused in some way or another thus smart choice is to use pin in ATM.

Introduction:

This project is to introduce a VHDL language, a hardware description language.  This language is used to model a digital system. VHDL-Very Hard Description Language is a verbose language with many constructs and also very difficult to understand. But the subset of VHDL is simple easy to understand. By using simple set of few features in this language, a reader can start writing models in VHDL. VHDL language has many features especially sequential language part form the ADA programming language.

Overview:

This language can be used as communication medium between chip vendors and CAD tool users and also between CAD and CAE tools. To describe an entity, VHDL provides 5 design units like entity declaration, architectural body, configuration declaration, package declaration and package body. An entity in VHDL is validated using an analyzer and simulator.

Simulation is a validation process which takes places once the model description is compiled into one or more design libraries.  A simulation can be performed on a configuration or on anentity declaration and an architecture body pair.  Elaboration and Initialization phases are two major steps which need to be carried out before preceding with the actual simulation. Identifiers, data objects, data types, operators are the basic elements of this language. 

Like C or Pascal, an entity behavior is expressed using sequential executed and procedural type code. A dataflow model gives the entity functionality without dealing with its structure. In structural modeling an entity is modeled in a way such that a set of components connected by signals.

In VHDL , compiled design units stored in specific design libraries and package is the term which represents how to store and share declarations that are common for many design units. VHDL describes its own bench models to validate the designed simulation hardware models.  Arbitrarily large designs can model using this language and also not imposing any limitation on the size of a design.  The elements of this language help to make large scale design modeling.

This paper discussed about the DOTSTAR tool which emerged for fast regular expression matching. DOTSTAR compiles regular expressions into a compact automation by using more manageable intermediate representations in a sequence. The resulting automation can easily search with a single pass without any backtracking. 

Overview: 

To define configurable rules for data parsing, regular expressions are a common choice.  Regular expressions help in performing online data filtering for many data intensive applications.  But with the regular expressions there is a possibility of increasing data rates and complexities by sets with hundreds of expressions. 

DOTSTAR addresses this problem by providing a software tool chain to compile large sets of user provided regular expressions first into a sequence of intermediate representations. Dotstar addresses the problems like amnesia and acalculia.  Amnesia is the inability of follow the multiple partial matches’ progress, whereas Acalculia is the inability to count the number of sub-expression occurrences.  Dotstar helps to avoid state explosion by using counting and status bits. Dotstar can reduce the memory requirements by elimination amnesia.

The five elements of Dotstar are classification engine, expander, compiler, compactor and runtime engine. Dotstar can accommodate the complex regex of Posix standard.  For the NIDS regex sets, Dotstar also compares well with the FPGA/accelerator implementations. 

Conclusions: 

DOTSTAR tool offers an automation to recognize small and large regular expression sets. Similar to Aho-Corasick automation, dotstar also can detect an exact matching of every regular expression including overlapping matches in a single pass.  Dotstar can efficiently parses both large and small user provided regular expressions with a very high matching speed for regex sets also Dotstar offers solution to acceleration.  The results given by Dotstar tool are better when compared to that of Regexlib and Boost tools. XML tokenization, SMTP parsing and Network intrusion detection are the three categories in which experimental evaluation has been carried out for Dotstar tool.
