Upper body power (UBP) is one of the most important factors affecting the performance of cross-country skiers during races. Although some initial studies have already attempted to predict UBP, until now, no study has attempted to apply machine learning methods combined with various feature selection algorithms to identify the discriminative features for prediction of UBP. The purpose of this study is to develop new prediction models for predicting the 10-second UBP (UBP10) and 60-second UBP (UBP60) of cross-country skiers by using General Regression Neural Networks (GRNN), Radial-Basis Functio...

In this dissertation, I have presented a comprehensive research on Bitcoin. Bitcoin was introduced in 2009. This is a decentralized digital currency and works like cash, but they are mined like gold (Volastro, CNBC Explains: How to mine bitcoins on your own, 2014). In this thesis, I will explain that how this currency works and how users can mine Bitcoins. Bitcoins mining is a very hard process, it is almost impossible to create Bitcoins on simple computer. You need specialist hardware to generate Bitcoins. Pool mining is quite popular these days, as numbers of people are taking interest in ma...

Despite the fact the human computer interface is the main facilitator of communication between the user and the computer system, its importance has been highly disregarded by system designers. This has resulted in many undesirable consequences, and in prescription and other healthcare systems, these problems are aggravated by the fact that not only are the users inconvenienced, but there are potential threats to the well-being of the patients under care as well. Many healthcare systems are often designed without considering the potential users of these systems. Consequently, the systems are cr...

The operational aspects of Lambda Calculus are studied as a fundamental basis for high-order functional computation. We consider systems having full reduction semantics, i.e., equivalence-preserving transformations of functions. The historic lineage from Eval-Apply to SECD to RTNF/RTLF culminates in the techniques of normal-order graph Head Order Reduction (HOR). By using a scalar mechanism to artificially bind relatively free variables, HOR makes it relatively effortless to reduce expressions beyond weak normal form and to allow expression-level results while exhibiting a well-behaved linear ...

This book presents a comprehensive process for visualization of interface metaphor for software. It is helpful in designing interactive user interfaces with magical super-affordances and definitive user experiences. As per the ancient Indian Vedic literature, metaphors are always conceived out of Vastu (entities having existence in our world). The visualization process given in the book shows how metaphorization could help in innovating highly experiential user interfaces, as one can create Avastu (non entities) by combining different objects and imaginative properties together. The main highl...

Wireless Metering Networks (WMN), a special class of Wireless Sensor Networks (WSN), consisting of a large number of tiny inexpensive sensor nodes are a viable solution for many problems in the field of building automation, especially if the expected lifetime of the network permits to synchronize the network maintenance with the schedule for routine maintenance of the building. In order to meet the resulting energy constraints, the nodes have to operate according to an extremely low duty cycle schedule. The existence of an energy efficient MAC Layer protocol, the adoption of a robust time sync...

Multi-Agent Geo-Simulation (MAGS) is a modelling paradigm which has attracted a growing interest from researchers and practitioners for the study of various phenomena in a variety of domains such as traffic simulation, urban dynamics, environment monitoring, as well as changes of land use and cover, to name a few. These phenomena usually involve a large number of simulated actors (implemented as software agents) evolving in, and interacting with, an explicit spatial environment representation commonly called Virtual Geographic Environment (VGE). Since a geographic environment may be complex an...

Multicarrier Modulation (MCM) has significant features over Single Carrier Modulation (SCM). Orthogonal Frequency Division Multiplexing (OFDM) is a special form of Multicarrier Modulation with its key feature of Orthogonality. Along with the several advantages of MCM or specifically OFDM, it has some drawbacks, too, in which High Peak to Average Power ratio is the dominant one. There are different techniques available to lower that PAPR. Every technique has its own benefit as well as shortcoming, so each is suitable for different circumstances. Tone Reservation is one technique in which a s...

The IP Multimedia Subsystem (IMS) is the basic network architecture for Next Generation Networks (NGN) which is intended to bridge the divide between the traditional circuit switched and packet switched networks, thereby providing a single network capable of providing all service offerings. IMS is based on the IP infrastructure and it enables the convergence of data, speech and video on the same network platform. The IMS forms the basis of Fixed Mobile Convergence (FMC), where fixed-line operators are striving to provide mobile access and mobile operators are trying to provide fixed access. Th...

During a conversation, listeners do not assimilate passively all of the speaker's words; they actively participate in the interaction providing information about how they feel and what they think of the speaker's speech. The speaker relies on signals emitted by the listener to know if he is listening or not, understanding or not, agreeing or not, etc. This informs the speaker on the success or failure of the communication and helps him to decide how to carry on with the interaction. In this thesis, to refer to signals provided by listeners, we adopt the term backchannel proposed by Yngve. We d...
