Abstract:

In this paper, we investigate the performance of a detector recently proposed by us that is applied in the relay station receiving signals from two terminals concurrently exchanging data in the two-way relaying system. This is one of the potential configurations to save resources in fifth-generation systems, similar to non-orthogonal multiple access, which is also considered for such systems. Two-way relaying can be implemented using physical network coding. This technique originates from the network coding idea, in which network nodes can perform some mathematical operations. The idea of the

Abstract:

Prior to the twentieth century, theories of knowledge were inherently perceptual. Since then, developments in logic, statistics, and programming languages have inspired amodal theories that rest on principles fundamentally different from those underlying perception. In addition, perceptual approaches have become widely viewed as untenable because they are assumed to implement recording systems, not conceptual systems. A perceptual theory of knowledge is developed here in the context of current cognitive science and neuroscience. During perceptual experience, association areas in the brain capt

Abstract:

In spatial modulation (SM), a single signal symbol is transmitted from a given physical antenna, where both the signal symbol and the antenna index carry information. SM with multiple active antennas (MA-SM) transmits several signal symbols from a combination of antennas at each channel use, thereby increasing the spectral efficiency. MA-SM is proposed in combination with a new 3-dimensional constellation, where signal symbols transmitted from a given antenna combination are rotated before transmission. In this paper, we derived an upper-bound on the error probability of the MA-SM as a functio

Abstract:

The main problem for AI consciousness is to operate within the right kind of AI. We distinguish between the traditional computing (GOFAI), and the computing based on stochastic pattern optimization. The latter will be called here computing at the edge of chaos. Optimization of learning patterns, which is the gist of its success, often happens between the areas of too much repetitive order and those of hard to predict and control stochastic processes. This is to change the focus from the opposition of symbolic versus sub-symbolic computing; symbols can appear at different granularities and the

A system is presented which is able to reconstruct the physical processes after the annihilation of particles in collider rings like LEP. It can be shown that the reconstruction task belongs to the class of NP-complete problems. Neither the conventional symbol processing approach of artificial intelligence nor connectionist systems alone satisfy the requirements of the application. A hybrid system is introduced in which a genetic algorithm acts together with a model-based hillclimbing component. The power of this method is based on the interaction of a dynamically and an inferentially working

Abstract:

As physical entities that translate symbols into physical actions, computers offer insights into the nature of meaning and agency. Physical symbol systems, generically known as agents, link abstractions to material actions. The meaning of a symbol is defined as the physical actions an agent takes when the symbol is encountered. An agent has autonomy when it has the power to select actions based on internal decision processes. Autonomy offers a partial escape from constraints imposed by direct physical influences such as gravity and the transfer of momentum. Swimming upstream is an example. Sym

To wit, there is a significant discontinuity in the degree to which human and nonhuman animals are able to approximate the higher-order, sy

The RGC is that the physical equations used to describe the dynamics of matter and/or fields should include the descriptions that not only the matter and/or fields are at rest, but also they move relative to this reference frame, and the structure of the spacetime of reference frame has been considered. The PERF is that any reference frame can be used to describe

Abstract:

Various theories highlight the importance of using the actor/environment as the ideal unit for theoretical and experimental focus. Clothing, placed as it is as the intermediary between body and environment, is typically treated as a symbol rather than as either an integral part of either the body or the environment. When clothing is considered an extension of the body, the historical development of clothing reflects persistent differences in the physical capabilities of the human animal and operates as an instrument for solo action. In addition, it is argued that due to the ecological mechanis

Abstract:

Heart rate exhibits spontaneous fluctuations that are mainly modulated by control loops within the autonomic nervous system. Assessing the dynamics of heart rate fluctuations can provide valuable information about regulatory processes and patho-physiological behavior. In this paper heart rate fluctuations and its entropy are assessed using an algorithmic information theoretic concept applying a data compressor. First, the beat-to-beat fluctuations of heart rate are binary coded for decreases and increases, respectively. Subsequently, those symbol sequences are compressed using the LZ77 algorit

Abstract:

Many prehistoric societies have left a wealth of inscribed symbols for which the meanings are lost. For example, the Picts, a Scottish, Iron Age culture, left a few hundred stones expertly carved with highly stylized petroglyph symbols. Although the symbol scripts are assumed to convey information, owing to the short (one to three symbols), small (less than 1000 symbols) and often fragmented nature of many symbol sets, it has been impossible to conclude whether they represent forms of written language. This paper reports on a two-parameter decision-tree technique that distinguishes between the

Abstract:

Universal filtered multicarrier (UFMC) is a low complexity promising waveform that provides quasi-orthogonal property among subcarriers. In addition, it can achieve much better out-of-band emission performance than orthogonal frequency division multiplexing (OFDM) system. Authors have proposed a hardware platform to implement a UFMC transmitter in this paper. Highly reduced complexity schemes for IFFT, filtering, and spectrum shifting are realized on actual hardware. This helps to achieve overall architecture of the transmitter at the cost of minimal FPGA resource usage. Hence, the overall des

Abstract:

Royal towns in Malaysia are the finest examples of traditional Malay towns, which are strongly associated with the long history of Malay Sultanates in Malaysia. This study aims to identify the significant characteristics that perhaps homogenously shared by the Malaysian Royal Towns to be inferred as the symbol and identity of the place. The study begins with thorough literature reviews of historical Malay manuscripts for some insights into how the traditional Malay towns were during the early 14th to the 19th century. From this, the study managed to identify three prominent characteristics tha

Abstract:

While neural networks are highly effective at learning task-relevant representations from data, they typically do not learn representations with the kind of symbolic structure that is hypothesized to support high-level cognitive processes, nor do they naturally model such structures within problem domains that are continuous in space and time. To fill these gaps, this work exploits a method for defining vector representations that bind discrete (symbol-like) entities to points in continuous topological spaces in order to simulate and predict the behavior of a range of dynamical systems.

Background. According semiotics, the text by which the fixation and preservation of information is carried out is the result of sign activity of man. The study of the patterns and nature of the notation and its elements is impossible without consideration of semiosis – the process of functioning of signs. The peculiarity of the musical activity is the fact that the graphic musical text finds a different form – the note signs are read by the interpreter and transform into sound. In other side, it is important to note that in the mind of the composer in the process of recording the work sound im
