The research paper Information Technology Seminars Computer Networks Triple Play Technology describes what Triple Play Technology is. It says that Triple play technology is nowadays considered as an indisputable trend. The differentiated service architecture is preferred over “hard quality of service” (QoS) integrated service architecture. Moreover it applies perfectly to triple play, as it satisfies differing QoS requirements. In addition, latest developments in the area of video and audio encoding impose new challenges in content delivery systems.

   What is VoIP: Voice over Internet Protocol (VoIP) is a protocol optimized for the transmission of voice through the internet or other packet switched networks. Voice over IP protocols carry telephony signals as digital audio, typically reduced in data rate using speech data compression techniques, encapsulated in a data packet stream over IP.The ability of VoIP is to transmit more than one telephone call down the same broadband connected telephone line. It’s also a location independent, just by having internet connection one can avail this service.

Disadvantages: Some broadband connections may have less than desirable quality. Where IP packets are lost or delayed at any point in the network between VoIP users, there will be a momentary drop-out of voice.

Wi-MAX: The research paper explains what Wi-MAX is it says that at first this wireless communication was started by infrared then Bluetooth then Wi-Fi and now Wi-MAX. The above devices were not capable for communicating for larger distances so one by one they got improved and now finally Wi-MAX has come into existence.

Conclusion:

The research abstract concludes on a note that the converged triple play service delivery is an emerging opportunity for enterprises and consumers, enabling them to enter a new era of user-centric multimedia communication and broadband entertainment. For service providers it is an opportunity to enter into or expand new markets as well as offering increased service differentiation to remain an attractive partner for providing solutions to an established customer base.

The research paper Component Object Model B Tech Seminar Topics for Computer Science describes what a Component Object Model is. It is suggested that COM is a specification or a set of rules provided such that language interop can be achieved. The objective of COM is that the code written in one language should be reused in the applications developed using other language. In order to specify a code as a component it is mandatory that the class definition has to inherit IUNKNOWN interface.

Methods in IUNKNOWN interface: The research paper identifies the following:

• QueryInterface à it is used to maintain the address of all the member functions defined in the class definitions in a VARRAY table structure.
• AddRef à It is used to increment the reference counter value by 1 whenever the application uses the definitions of the form component.
• Release à whenever the application which uses the COM component definitions is closed in a normal procedure then Release Method is used to release the reference counter information.

What COM Does: The research paper explains COM. It says that whenever a COM type application uses the definitions of the in process COM then a request will be given to the COM server where the component will be identified based on its GUID and processing of the component will take place at the PMA [ Private Memory Area ] of the OS and the request will be given back to the application. The paper also states the advantages and limitations of COM as follows:

• Advantages à The performance of the application will be very fast.
• Limitations à Always a IN process component depends on a application. The Component can’t be used independently.

Conclusion:

The presentation concludes on a note suggesting that whenever the dot net application uses the definitions of the COM Component a request will be given to the CLR which uses the COM marshalling resource and identifies the application uses the definition of the COM Component and it defines a Runtime Callable Wrapper which sends a request to the Com Server where the Component is identified based on its GUID and the definitions of the COM component will be returned to the RCW and based on that definitions a relevant .net interop COM will be defined which will be used by the applications.

The research paper Collective Intelligence Computer Science Engineering Seminar Topics explains in detail what collective intelligence is Collective intelligence is defined as the ability of a group to solve more problems than its individual members. The research paper posits that that the obstacles created by individual cognitive limits and the difficulty of coordination can be overcome by using a collective mental map (CMM). A CMM is defined as an external memory with shared read/write access that represents problem states, actions and preferences for actions.

According to collective intelligence A system is more intelligent than another system if in a given time interval it can solve more problems, or find better solutions to the same problems. A group can then be said to exhibit collective intelligence if it can find more or better solutions than the whole of all solutions that would be found by its members working individually.

Examples of Collective Intelligence: The research abstract quotes pertinent examples pertaining to Collective Intelligence. It says that all organizations, whether they are firms, institutions or sporting teams, are created on the assumption that their members can do more together than they could do alone.

Collective Mental Maps: The research abstract casts light on Collective Mental Maps. It says that a collective mental map functions first of all as a shared memory. Various discoveries by members of the collective are registered and stored in this memory, so that the information will remain available for as long as necessary.

Benefits of CMM: The paper suggests some obvious benefits of CMM. Instead of being limited to the few links present in the document being consulted, a user would be able to choose from an extensive, but intelligently selected list of related documents, ordered by the probability that they would be relevant. The paper also quotes examples saying that such a list of suggested links has already been implemented by the Alexa Corporation and incorporated in the Netscape and Internet Explorer browsers.

Conclusion:

The research paper concludes on a note describing CMM and calling it a “global brain”. Although the first commercial applications of some of these techniques are already appearing, it is clear that still a lot of research needs to be done before it can be certain that the proposed algorithms are ready for the task. There are many possible variations on the methods discussed, and there are many other sources of collective knowledge to be mined. The best-combined method will likely be found by testing out a variety of approaches in a variety of circumstances.

The research paper Code Division Multiple Access System Computers Seminar Topics suggests that CDMA (Code Division Multiple Access) is one method for implementing a multiple access communication system. The research paper explains what multiple access is. It says that MULTIPLE ACCESS is a technique where many subscribers or local stations can share the use of the use of a communication channel at the same time or nearly so despite the fact originate from widely different locations.

About CDMA: The research paper says that CDMA is a hybrid combination of FDMA and TDMA. For example, frequency hopping may be employed to ensure during each successive time slot, the frequency bands assigned to the users are recorded in random manner. During time slot 1, user 1 occupies frequency band 1, user 2 occupies frequency band 2, user 3 occupies band 3 and so on. During time slot 2, user 1 hops to frequency band 3, user 2 hops to band 1, user 3 hops to band 2, and so on.

What is the meaning of CDMA? The research paper explains that in the CDMA technology. the users are spread across both frequency and time in the same channel. Here, unique digital codes, rather than separate RF frequencies or channels are used to differentiate subscribers. The codes are shared by both the mobile stations (cellular phone) and the base station, and are called “pseudo random code sequences” or “pseudo-noise code sequences”.

Advantages of CDMA Technology: Many advantages have been elucidated in the paper about the CDMA Technology. It says that

• Availability of very low cost, highly dense digital integrated circuits, which reduce the size, weight and cost of the subscriber station to an acceptably low level.
• Realization that optimal multiple access communication requires that all user station regulate their transmission power to the lowest that will achieve adequate signal quality.

Conclusion:

The research paper concludes on a note saying that CDMA is radically new concept in wireless communication. CDMA has gained widespread international acceptance by cellular radio system operators as an upgrade that will dramatically increase both their systems capacity and the service quality.

The research paper CDMA Technology CSE & IT Seminar Topics delves deeper into the CDMA ( code division multiple access) technology. It says that CDMA TECHNOLOGY makes existing mobile handset more efficient and attractive. CDMA (3G) mobile devices and services will transform wireless communications into on-line, real-time connectivity. 3G wireless technology will allow an individual to have immediate access to location-specific services that offer information on demand.

This research abstract presents an overview of current technology trends in the wireless technology market, a historical overview of the evolving wireless technologies and an examination of how the communications industry plans to implement 3G wireless technology standards to address the growing demand for wireless multimedia services.

About CDMA: It is suggested in the research abstract that it was the founders of QUALCOMM who realized that CDMA technology could be used in commercial cellular communications to make even better use of the radio spectrum than other technologies. They developed the key advances that made CDMA suitable for cellular, then demonstrated a working prototype and began to license the technology to telecom equipment manufacturers. CDMA was developed by QUALCOMM Incorporated, a company in San Diego, California. QUALCOMM engineers decided to do something different and applied spread spectrum techniques to a multiple access system, which ultimately became CDMA.

Scope of CDMA: The paper suggests that CDMA offers an answer to the capacity problem. The paper says that the key to its high capacity is the use of noise-like carrier waves, as was first suggested decades ago by Claude Shannon. Instead of partitioning either spectrum or time into disjoint “slots” each user is assigned a different instance of the noise carrier. While those waveforms are not thoroughly orthogonal, they are nearly so. Practical application of this principle has always used digitally generated pseudo-noise, rather than true thermal noise.

Conclusion:

The research abstract concludes on a note suggesting that interworking between access networks implementing enhanced versions of current technologies for broadcast cellular and short-range communications should provide a good first solution for CDMA(3G) services. It suggests that this technology map can be extended to include access technologies for transmission at more than 50 Mbit/s for fast moving users as well as ultra wide band systems for wide area coverage.

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.
