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.

The research paper CSE Seminar Topics with PPT Bio Informatics The Emerging Discipline describes the emerging role of Bioinformatics in establishing the need to understand the code of life, DNA. DNA the basic molecule of life directly controls the fundamental biology of life. It codes for genes which code for proteins which determine the biological makeup of humans or any living organism. It is variations and errors in the genomic DNA which ultimately define the likelihood of developing diseases or resistance to these same disorders.

The scope of Bioinformatics: The research paper clearly elucidates the scope of Bioinformatics. It says that the science of bioinformatics or computational biology is increasingly being used to improve the quality of life and has developed out of the need to understand the code of life, DNA. Massive DNA sequencing projects have evolved and added in the growth of the science of bioinformatics. DNA the basic molecule of life directly controls the fundamental biology of life.

Application of Bioinformatics: The research paper talks about the various applications of Bioinformatics. It says that Bioinformatics is the applications of computer technologies to the biological sciences, particularly genomics, with the object of discovering knowledge. This is often understood to include high-through output screening of genes and proteins, chemical information system, clinical data, the activity of drugs in the body-all of that got lumped in.

Bioinformatics is any application of computation to the field of biology, including data management, algorithm development and data mining.

In the bioinformatics arena primary focus is on use of the information, as well as on acquisition, preparation, and storage. All needs to be considered within the framework of information for Acquisition of information and documents, including creation of meta-data, submission of electronic media, and communication interfaces.

The research abstract Computer Science Seminar Topics Beowulf System clearly explains what clusters are. It later proceeds to explain the Beowulf system as an important breakthrough in the area. Clusters are essentially a group of computers connected over a network, which work in tandem to look like a single computer to an outside user. Clustering is most widely recognized, as the ability to combine multiple systems in such a way that they provide services a single system could not. Clustering is used to achieve higher availability, scalability and easier management.

What is Beowulf: Beowulf was a cluster developed by Thomas Sterling of Center Excellence in Space Data and Flight Information Sciences(CESDIS) at NASA Goddard Space Flight Center[1],in 1994.That cluster employed 16 Intel 100MHz DX4 PCs each with 16 MB RAM and 2 Ethernet cards.

A typical Beowulf system may comprise 16 nodes interconnected by 100 base T Fast Ethernet. Each node may include a single Intel Pentium II or Digital Alpha 21164PC processor, 128-512 MBytes of DRAM, 3-30 GBytes of EIDE disk, a PCI bus backplane, and an assortment of other devices. At least one node called master node will have video card, monitor, keyboard, CD-ROM, floppy drive and so forth.

 Beowulf is a parallel computer. It will not just run a uniprocessor “dusty deck” and benefit from all of the computing resources. A site must expect to run parallel programs, either acquired from others or developed in-house. A site without such skill base should probably not follow the Beowulf path. Beowulf is loosely coupled and is a distributed memory environment.

The research abstract CSE seminar topics with abstract Bayou System elucidates the various functionalities of BAYOU a replicating system. The research paper explains that Bayou is a replicated, weakly consistent storage system designed to support collaborative application in distributed computing environment with varying network connectivity. A typical example of such an environment is a system with mobile hosts that may disconnect over period of time, connect only through low bandwidth, radio networks or connect occasionally with expensive cellular modems.

BAYOU System Model

In Bayou replication management is undertaken by Bayou servers. Each server holds a complete replica of the data. The data model provided by current implementation of Bayou is a ‘relational database’, although other data models could be used as well. Bayou is chosen as a relational model because of its power and flexibility. In particular it naturally supports fine-grained, structured access to the data, which is useful for application specific conflict detection and resolution mechanism, which is desired.

Bayou applications are free to run and update replicas without locking. Bayou guarantees that the distributed strong system will move towards eventually consistency by imposing a global order on write application and by providing propagation guarantees.

What BAYOU does

One feature of Bayou that application can impose its own semantics on the operation executed at a replica. To this end, Bayou reads and writes are not the simple operations supported by most databases.  Instead they include additional application supplied information, which ensures that application will receive the required level of services from the system.

Conclusion

The research paper suggests that Bayou model supports client-supplied anti-entropy policies. Thus clients can influence when to propagate their changes to other servers. The ability to regulate when updates are propagated is important for applications like collaborative software development where users must ensure that a coherent picture of the code base is available at specific times.

The research paper seminar topics for cse 2011 Asynchronous Transfer Mode (ATM) Switching explains the functionality of ATM- Asynchronous Transfer Mode Switching. The research paper defines ATM. It suggests that ATM does not stand for automatic teller machine. In the telecommunication, it stands for Asynchronous Transfer Mode, in   which data is sent asynchronously.  This mode is another fast packet switching mode. Asynchronous  transfer  mode  (ATM)  is  a  technology  that  has  his  its  history  in  the  development  of  broadband  ISDN  in  the  1970s  and  980s.  Technically, ATM can be viewed as an evolution of pocket switching. The paper describes pocket switching in detail. ATM  is  also  a  set  of  international  interface  and  signaling standards  defined  by  the  International  Telecommunication  Union- Telecommunications  (ITU-T)  Standards  Sector  (formerly  the  CCITT).

The research paper talks in depth the various functionalities offered by ATM. ATM  provides  a  way  of  multiplexing  many  sources  of data  onto  a  common  cells  stream.  Regardless of  speed  of  the inputs.  This  greatly  improves   flexibility,  enabling  provision  of bandwidth  on  demand. ATM  is  a  cell-switching  and  multiplexing  technology  that  combines  the  benefits  of  circuit  switching  (guaranteed  capacity  and  constant transmission  delay)  with  those  of  packet  switching  (flexibility  and efficiency  for  intermittent  traffic).  It  provides  scalable  bandwidth  from a  few  megabits  per  second  (Mbps)  to  many  gigabits  per  second (Gbps).  Because  of  its  asynchronous  nature,  ATM  is  more  efficient than  synchronous  technologies,  such  as  time-division  multiplexing (TDM).

Three types of ATM services exist: permanent virtual circuits (PVC), switched virtual circuits (SVC), and connectionless service (which is similar to SMDS). ATM supports two types of connections: point-to-point and point-to-multipoint.

1. *High   performance via   hardware switching
2. Dynamic bandwidth for heavy traffic
3. *Class- of –service support for media
4. Scalability in speed and network size
5. Common LAN / WAN architecture
6. Opportunity for simplification via VC architecture
7. International standard compliance

Conclusion

The research paper concludes on a note that ATM  is  a  technology  that  can  handle  all  types  of traffic  ( voice,  video  and  data)  multiplexed  on  the  same  network  . In  an  ATM  network  band  width  can  be  reassigned  in  real  time  to different  traffic  based  on  demand.  ATM  is  the  only  technology  common   to  all  environments   from  LAN  to  GAN .
