Main feature of the cohesion is connection between sentences in the text. It describes the ways in which components of sentences of a text are mutually connected (grammatically and lexically). Cohesion is non-structural text forming relations because cohesion depends not on structure but on semantic relations and it makes the text a semantic unit. / Pagrindinis kohenzijos tikslas yra ryšys tarp sakinių tekste. Ji apibūdina abipusį ryšį kuris jungia sakinius(gramatinį ir leksinį). Kohenzija yra nestruktūrinis teksto formavimo ryšys, ji nepriklauso nuo struktūros, tai semantinis ryšys ir tuo pačiu jis nurodo, kad tekstas yra semantinė dalis.

The de-facto standard for dysarthric intelligibility assessment is a subjective intelligibility test, performed by an expert. Subjective tests are often costly, biased and inconsistent because of their perceptual nature. Automatic objective assessment methods, in contrast, are repeatable and relatively cheap. Objective methods can be broken down into two subcategories: reference-free, and reference based. Reference-free methods employ estimation procedures that do not require information about the target speech material. This potentially makes the problem more difficult, and consequently, there is a deficit of research into reference-free dysarthric intelligibility estimation. In this thesis, we focus on the reference-free intelligibility estimation approach. To make the problem more tractable, we focus on the dysarthrias of cerebral palsy (CP). First, a popular standard for blind speech quality estimation, the ITU-T P.563 standard, is examined for possible application to dysarthric intelligibility estimation. The internal structure of the standard is discussed, along with the relevance of its internal features to intelligibility estimation. Afterwards, several novel features expected to relate to some of the acoustic properties of dysarthric speech are proposed. Proposed features are based on the high-order statistics of parameters derived from linear prediction (LP) analysis, and a mel-frequency filterbank. In order to gauge the complimentariness of P.563 and proposed features, a linear intelligibility model is proposed and tested. Intelligibility is expressed as a linear combination of acoustic features, which are selected from a feature pool using speaker-dependent and speaker-independent validation methods. An intelligibility estimator constructed with only P.563 features serves as the `baseline'. When proposed features are added to the feature pool, performance is shown to improve substantially for both speaker-dependent and speaker-independent methods when compared to the baseline. Results are also shown to compare favourably with those reported in the literature. / Thesis (Master, Electrical & Computer Engineering) -- Queen's University, 2011-09-28 18:44:51.103

We can think about ourselves in a variety of ways, but only some of the thoughts that we entertain about ourselves will be thoughts which we know concern ourselves. I call these first-person thoughts, and the component of such thoughts that picks out the object about which one is thinking—oneself—the self-concept. In this thesis I am concerned with providing an account of the content of the self-concept. The challenge is to provide an account that meets two conditions on first-person thought. The account must show how we are aware of ourselves when we entertain first-person thoughts, so that we have an account that establishes the cognitive significance of first-person thoughts. But, in addition, this awareness must be as robust as the thinker’s ability to entertain first-person thoughts if our account is to respect the guaranteed referential success of the self-concept. I introduce both the subject matter of the thesis, and the constraints on a satisfactory account of that subject matter in the first chapter. In the second chapter I then set up a further problem: much of our self-knowledge is knowledge of our current mental states and it is often argued that we know about and can ascribe those mental states on the basis of introspection alone. The first constraint on an account of first-person thought described in the preceding paragraph requires that we be aware of ourselves in some way if our thoughts are to have the special cognitive significance of first-person thoughts. Yet, I argue, we neither do nor can introspectively observe a subject of thought and experience when we come to know about our mental states and experiences. The failure of introspection to supply us with perceptual information about a subject of thought presents us with the further potential problem. According to Fregean semantics sense determines reference: we count on the content of the elements of thought to determine the reference of terms that are used to express those elements. If we do not introspectively observe a subject of thought then we seem to be at a loss to account for the concept and we are at risk of having to accept that neither the self-concept nor the first-person pronoun are referential. In the remainder of my thesis I consider various responses that we can offer to this problem. First, I examine whether we can avoid the problem with an alternative account of first-person reference according to which reference is fixed by a reflexive rule, and whether we can also base an account of first-person thought on this account of first-person reference. Secondly, I look at the descriptivist view of first-person thought which could potentially provide both an account of first-person thought and first-person reference. These two suggestions must be rejected on the grounds that they fail to accommodate the special cognitive significance of first-person thought. A third approach to first-person thought argues that we employ an objective self-concept when we think about ourselves, a concept that is informed by bodily experience, rather than by introspective observation of a subject. Yet such an account cannot make sense of first-person thoughts in which we question our own embodiment. Lastly I consider whether it is possible to explain the cognitive significance of first-person thought in terms of non-conceptual first-person contents.

The McTronX research group of the North–West University has over some years established a knowledge base in active magnetic bearing (AMB) systems. In 2009, an AMB system that met industrial standards in being robust, reliable and economical was developed by the research group. The digital control of the AMB system was implemented with the use of a dedicated single–board computer and communication hardware that interface with the motor drive electronics, power amplifiers and sensor drive units of the AMB system. A Xilinx® field programmable gate array (FPGA), connected to the single–board computer, was used to control the AMB system. The AMB system was designed to be used in a helium blower application and to form a basis for AMB and digital control research. A programmable logic controller (PLC) is connected to the controller to operate the AMB system. To establish communication between the PLC and the FPGA, the Fieldbus standard PROFIBUS DP was chosen as being a robust industrial standard communication protocol. To reduce the cost of the entire system, the need arose to implement the PROFIBUS DP protocol on the current FPGA of the system. This project involves the research, design, implementation, verification and validation of the PROFIBUS DP protocol on a Xilinx® Virtex©–5 FPGA. The PROFIBUS DP standard was researched, analyzed and developed in VHDL for the specific Xilinx® Virtex©–5 FPGA. The implemented protocol is used to establish a standardized PROFIBUS DP network between the PLC and the FPGA controller. Through simulation the basic protocol was tested and later implemented in the real–time environment. Intensive verification and validation was done to ensure that the developed protocol conforms to the robust PROFIBUS DP standard and simultaneously meet the requirements and specifications of the AMB control system. This dissertation documents the entire PROFIBUS implementation process, from standard analysis through to verification and validation of the developed protocol. In conclusion, the developed protocol is compared against a commercial off–the–shelf PROFIBUS PMC module. It was found that the VHDL–based PROFIBUS DP protocol not only competes well with the commercial PROFIBUS device, but also outperforms the device in various aspects. / Thesis (M.Ing.

Master of Visual Arts / We all play roles in life. This paper is a personal reflection on identity, and the questioning of this identity. The writer allows the reader into a dream like environment where a life role is acted out as autobiographical narrative through appropriation and reference to the other. Theoretical sources include Walter Benjamin, Roland Barthes, Jacques Lacan and Joseph Kosuth. With reference to these sources, comparison is made between Jan Vermeer’s seventeenth century portraits of women and Bertolt Brecht’s early twentieth century epic theatre.
