The research abstract Building Your Own Web Server Computer science seminar topics with Abstract explains how to build our own web server. It elucidates all the technical aspects involved therein. The abstract talks about Webster2 and its detailed construction. It says that Webster2 is the fourth generation web server designed and built and fully capable of supporting all our current web server needs. It has the stability and performance necessary for serving pictures, large documents, music, and video files for our friends etc.

Generations of Webster: The research paper identifies the webster2 generations and explains in depth the technical aspects of all the four generations of Webster2. The abstract suggests that besides the energy conservation issue, Webster can be put on the Internet without concern for viruses and spyware. Webster’s software is written entirely in C++ with no underlying operating system with exploitable security flaws. Since, by design, there isn’t any write access to the underlying file system, it is unlikely the website content can be compromised. Finally, since Webster supports basic authentication, access to the website can be controlled with a username and password.

Protocols uses in Webster2 design: The paper explains then different protocols used in Webster2 design. It comments on:

• DHCP. Webster2 can use DHCP to obtain its networking parameters (IP address, and so forth) from a DHCP server on the network to which it is attached. If DHCP isn’t used, the networking parameters can be set statically via entries in a configuration file.
• DNS. DNS is like a phone book for the Internet for turning host names into IP addresses. DNS entries must be in place so that Webster2 can be found on the Internet by name. The research paper also explains different protocols like NTP, FTP, and HTTP.

Conclusion:

The paper concludes by considering that Webster2 was fun and easy to build and helps conserve energy. Webster2 is the fourth-generation web server designed and built and is fully capable of supporting all the current web server needs. It has the stability and performance necessary for serving pictures, large documents, music, and video files for family and friends.

The research paper Computer Science Seminar Topics Brain Computer Interface begins by describing the size of human brain which is of the size of a deflated volley ball and weighs around 3 pounds. The research paper suggests that a Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer. The 100 billion neurons communicate via minute electrochemical impulses, shifting patterns sparking like fireflies on a summer evening, that produce movement, expression, words.

Approach: The research paper describes how the process is achieved. It says that the Invasive BCIs are implanted directly into the grey matter of the brain during neurosurgery. As they rest in the grey matter, invasive devices produce the highest quality signals of BCI devices but are prone to scar-tissue build-up, causing the signal to become weaker or even lost as the body reacts to a foreign object in the brain. The paper says that the easiest and least invasive method is a set of electrodes — a device known as an   electroencephalograph (EEG) — attached to the scalp. The electrodes can read brain signals.

Potential Users of BCI Systems

The research paper segregates the potential users of BCI systems as

1.      Individuals who are truly unlocked.

2.      Individuals who have a very limited capacity for control, e.g., useful eye movement.

3.      Individuals who retain substantial neuromuscular control.

The research Paper posits the recent breakthrough in BCI saying that Advanced Telecommunications Research Institute International (ATR) and Honda Research Institute Japan Co., Ltd. have jointly developed base technology for a new BMI (brain machine interface) to operate robots based on the human brain’s activity patterns.

Scope of BCIs: The paper suggests that one of the most exciting areas of BCI research is the development of devices that can be controlled by thoughts. Some of the applications of this technology may seem frivolous, such as the ability to control a video game by thought.

Conclusion:

The research article concludes by quoting various possible advantages of Brain Computer Interface (BCI). It says that there are many useful applications of brain computer interface. It can be very helpful for people with moving disabilities as human – machine interface. But it can be also used for control of human body muscles. There are also many possibilities of BCIs in the military domain.

The research paper Computer Science Seminar Topics Bluetooth Security describes different ways of data transfer through Bluetooth in a secure way. This paper gives information about the security measures of Bluetooth, the paper examines the Bluetooth security architecture in detail, how it should be different from the old security measures of the cable-connected world and are they sufficient enough, so that Bluetooth can be used for everyday communications.

Applications of Bluetooth: The research paper comments on various applications of Bluetooth and many more beyond mentioned.

Examples:

• Wireless headsets for cell phones for hands-free, wire-free phone calls.
• Wireless PC Mouse connection to the PC using Bluetooth.
• Wireless printing between a PC or handheld and a Bluetooth enabled printer.
• Wireless barcode scanner input for retail and warehousing.
• Automated synchronization of Personal Digital Assistant (PDAs) and PCs using Bluetooth.
• Ad hoc networking and file sharing between PCs, PDAs & laptops in a meeting.
• Automated cell phone dialing from a laptop’s contact database with logging of the activity on the laptop.

Benefits of Bluetooth: The paper states that the most basic benefit from Bluetooth is of simple cable replacement between two devices. For many situations where the physical elimination of inconvenient cables that take space and limit device placement. In industrial and commercial applications, the presence of wires creates problems and task interference issues. The wide range of device types and standard interface make by Bluetooth which allows selection of devices optimized each for their particular functions.

Security Modes: The paper states that each Bluetooth device can work on one of the three security modes. Depending on whether a device uses a semi link key or a master key, there are several encryption modes available. If a unit key or a combination key is used, broadcast traffic is not encrypted. Individually addressed traffic can be either encrypted or not. If a master key is used, there are three possible modes. All the three modes have been meticulously explained in the paper.

Conclusion:

The abstract concludes on the note that the Bluetooth’s security seemed to be adequate only for small ad hoc networks, such as a network of the participants in a meeting. Connecting a Personal Digital Assistant (PDA) to a mobile phone using Bluetooth may also be secure enough. The paper puts forth a valid question asking whether Bluetooth is secure enough for larger networks, money transfers and transferring other sensitive information.

The research paper CSE Seminar Reports Bluetooth Technology talks about the Bluetooth Technology. It goes about explaining the working aspects of Bluetooth. The paper elucidates advantages of the technology, security concerns and finally the possible developments in the technology in future. The paper says that Bluetooth is an open specification for short-range wireless communication and networking mainly intended to be a cable replacement between portable and/or fixed electronic devices.

What is Piconet: The paper explains what Piconet is. It suggests that when two Bluetooth enabled devices come within range of one another, one of them assumes the role of master of the communication and the other becomes the slave. The Master device establishes synchronization among all slave devices by using its clock and hopping sequence. This simple “one hop” network is called as piconet. There is no limit on the maximum number of slaves connected to one master. Many graphical representations of the various steps and procedures involved in Bluetooth information transfer are illustrated in the research paper.

Conclusion:

The research paper concludes on a note that the Bluetooth standard enables the formation of scatternets, with which mobile ad hoc networks (MANETs) may be established. The paper presents two protocols to solve the problem of scatternet formation. The first protocol organizes the Bluetooth nodes into a rooted tree, the bluetree, in which each node participates at most two piconets, reducing piconet switching overhead. A prominent solution also considers the problem of limiting the number of slaves that each master has to control.  The paper presents a second protocol with a more distributed behavior. Using simulation has demonstrated that in a large population of nodes the speed of the formation procedure outperforms that of the first one. In the second solution the piconet switching overhead is still well contained, since each node is allowed to assume at most three roles.

The research paper CSE Seminar Topics with Bluetooth Technology explains in depth about Bluetooth Technology. The research paper suggests that Bluetooth, the new low-cost radio technology, is designed to unite or connect all different types of devices to effectively work as one. By uniting devices, Bluetooth eliminates the need for cabling in a wide range of products, including cellular phones, PCs, headphones, audio equipment, printers, and many more.

How Bluetooth Works: The paper explains the in depth working aspects of Bluetooth technology. It says that the technology of Bluetooth centers around a 9mm x 9mm microchip, which functions as a low cost and short range radio link. Bluetooth Technology provides a 10 meter personal bubble that supports simultaneous transmission of both voice and data for multiple devices. Up to 8 devices can be connected in a piconet, and up to 10 piconets can exist within the 10 meter bubble. Each piconet supports up to 3 simultaneous full duplex voice devices. The gross data rate is 1 Mb/s, but the actual data rate are 432 kbps for full duplex transmission, 721/56kbps for asymmetric transmission, and 384 kbps for tms2000 transmission.

The paper explains that the Bluetooth network arrangements (topology) can   be either point-to-point or point-to-multipoint. Any unit in a piconet can establish a connection to another piconet to form a scatternet.

Some techniques establishing the Bluetooth Connections are explained in the research abstract. They are:

1. Stand by

2. Page inquiry

3. Active

4. Hold

5. Sniff

6. Park

Future of Bluetooth: The paper suggests that Bluetooth is a continually expanding technology. There are plans to add many new application profiles. With over 1800 companies working on Bluetooth, the future could not be brighter. With a strong special interest group behind Bluetooth, the standardization of the application profiles is almost assured.

Conclusion:

The research article concludes on a note quoting the many advantages offered by Bluetooth technology. It suggests some examples like automatic check-in, the three-in-one phone etc.

The research paper CSE Seminar Topics Technical Latest Blue Ray Disk aims at explain what a blue –ray disc is. It talks about the disc, its functionalities and scope. The research paper explains the advantages of Blu-Ray Disc (BD) over the traditional discs. It says that since BD uses blue lasers, which have shorter wavelengths than traditional red lasers, it can store substantially more data in the same amount of physical space as previous technologies such as DVD and CD.

How BD Works: The research paper also suggests how a BD operates it says that when a diode is forward biased, holes from the p-region are injected into the n-region, and electrons from the n-region are injected into the p-region. If electrons and holes are present in the same region, they may radioactively recombine—that is, the electron “falls into” he hole and emits a photon with the energy of the band gap. Further light is cast on the ‘working’ aspect of BD in the research paper.

Conclusion:

The abstract concludes on a note saying that BD still has a long way to go. But still it speaks optimistically saying that BD may hit the market with consumers clamoring for faster transfer speeds and storage capacity. BD answers such complicated questions. Speed and storage capacity seem to be notable advantages of BD technology, it’s possible that the industry is headed to a point where BD sales will one day outstrip DVDs. The paper says that it’s too early to call the game just yet, but this will be an interesting technological development to follow.

The research paper CSE Seminar Topics Technical Blue Ray Disk identifies the need to store data on an optical disc and the indispensable role played by the blu-ray disc. The paper posits that the Optical disc has high storage capacity, advanced security and privacy features and the A/V high quality O/P (generally video) of the media files stored on it makes it quite unique & gives an edge over the others, letting BD to be widely adaptable in every application possible. Blur-ray Disc or BD is the next generation digital video disc.

The research paper talks and clarifies the encryption issues pertaining to BDs. It says that Blu-ray has an experimental security feature titled BD+ that allows for dynamically changing encryption schemes. Should the encryption be compromised, manufacturers can update the encryption scheme and put it on all new discs, preventing a single crack from opening up the entire specification for the duration of its lifetime.

Conclusion:

The abstract concludes on a note saying that it would definitely take time for the Blu-Ray disc to hit the market & completely takeover the DVD share hold.

This research paper CSE Seminar Topics 2010 Biometric World explains the various aspects of biometrics hence named BIOMETRIC WORLD.  A special focus is laid on Iris Recognition and Retina Scan. Even a particular emphasis is placed on the variations of Iris & Retinal Scanning. The biometric applications which well suit the market demands are stated and this proceeds with the predictions of future along with the present scenario.

Retinal Scan: The paper elucidates the nuances involved in retinal scan. The paper says that the retinal scan uses a low-intensity light source and a delicate sensor to scan the pattern of blood vessels at the back of the retina, a pattern unique to each individual. Retina scan devices read through the pupil which require the user to situate his/her eye within 1/2 inch of the capture device, and to hold still while the reader ascertains the patterns. The user looks at a rotating green light as the patterns of the retina are measured at over 400 points.

Advantages: This leads to a very high level off accuracy in comparison to most other biometrics.

Iris Scan: The research paper suggests that Iris identification technology is a tremendously accurate biometrics when compared to all the other biometrics. Iris recognition can account for the detection of papillary (pupil) changes; reflections from the cornea, detection of contact lenses on top of the cornea and use of infrared illumination to determine the state of the sample eye tissue.

Conclusion:

The research paper concludes saying that there is a need for the invention of some of the biometric technologies which are inexpensive, user-friendly and which are of less cost and high accuracy. An organization may seek the help of feedbacks to understand what can be improved, to let them have the sorts of risks that are acceptable, and what has to been done to minimize the organization’s exposure to them. It’s important to build systems and networks in such a way that the user is not constantly reminded of the security system around him.

The research paper CSE Seminar Topics Free Download Bio Informatics talks about Bioinformatics and the role of software engineers in the emerging discipline. The research paper clearly elucidates that Bioinformatics is the application of computers in biological sciences. 

It is concerned with capturing, storing, graphically displaying, modeling and ultimately distributing biological information. It is becoming an essential tool in molecular biology as genome projects generate vast quantities of data.

The relation between Computers and Biology: The research abstract draws an interesting relationship between biology and computers. It says that Bioinformatics is the symbolic relationship between computational and biological sciences. 

The ability to sort and extricate genetic codes from a human genomic database of 3 billion base pairs of DNA in a meaningful way is perhaps the simplest form of Bioinformatics.

Moving on to another level, Bioinformatics is useful in mapping different people’s genomes and deriving differences in their genetic makeup through pattern recognition software. But that is the easiest part. 

What is more complex is to decipher the genetic code itself to see what the differences in genetic makeup between different people translate into in terms of physiological traits. The paper elucidates the above-mentioned facts by giving experimental references.

Application: The research abstract explains Computational simulation of experimental biology which is an important application of Bioinformatics, which is referred to as “in silico” testing. This is perhaps an area that will expand in a prolific way, given the need to obtain a greater degree of predictability in animal and human clinical trials.

Drawbacks: The research paper identifies certain limitations it states that today, the use of computers to model such processes is limited by, and must be placed in the context of, the current limits of understanding of these central themes.

At the outset, it is important to recognize that the rules of protein folding are still not fully understood; it cannot be invariably said that a particular sequence or a fold has arisen by divergent or convergent evolution; and it cannot necessarily be diagnosed as protein function, given knowledge only of its sequence or of its structure, in isolation.

Conclusion:

The research paper concludes by quoting the strides made by Bioinformatics in various fields. DNA forensics, bio-archeology, risk assessment, application of microbial genomics etc.
