In a background in which transparency and reliability are fundamental cornerstones in financial statements, appropriate management of operational risks is a growing concern. As a result, risk management is increasingly necessary and a vital tool to reduce the opportunities for deviations from the route plan. However, the literature on the subject addresses, mainly, companies in the financial sector, showing a lack of data for organizations in other industries. Within this context, this study aims to present the implementation of operational risk management in the Integrated Receiving (IR) area of a National Publisher. The analysis of this study was based on the concepts of COSO (Committee of Sponsoring Organizations of the Treadway Commission) methodology and made possible using Control Self Assessment (CSA) methodology, in addition to the interventionist approach. CSA methodology provides the identification of risks by managers of the area under analysis. However, in order to develop a theoretical contribution, this study analyzed data referring to employees in IR area. After data were collected, the implementations of the necessary corrective actions were discussed and negotiated with the concerned manager. The result was a success throughout the whole process of implementation; in addition, the participation of all employees were beneficial and constructive for the company in order to determine weaknesses of the area. The main benefit observed was the dissemination of the risk culture among the participants of this work and an improvement in the control environment for the company. Results should be analyzed considering the limitations of this work, as the company studied belongs to a specific sector. Therefore, as a suggestion for future research, there is a need to expand the number of companies and internal areas to be studied, comparing the conclusions with those of this study. / A gestão de riscos é um dos mais importantes recursos para a sobrevivência das organizações. Em um cenário de demanda por transparência e confiabilidade nas demonstrações financeiras, o adequado gerenciamento de riscos operacionais é preocupação cada vez mais presente. Em razão disso, a gestão de riscos torna-se um instrumento de extrema importância para minimizar as ocorrências de perdas nas organizações. Porém, a literatura sobre o assunto aborda, principalmente, empresas do setor financeiro, havendo uma carência de dados para organizações pertencentes aos demais setores do mercado. É nesse contexto que o presente estudo teve como objetivo principal a implementação do gerenciamento de riscos operacionais na área de Recebimento Integrado (RI) de uma Editora Nacional. As análises deste trabalho tiveram por base os conceitos da metodologia COSO (Committee of Sponsoring Organizations of the Treadway Commission) e foram viabilizadas com a utilização da metodologia CSA (Control Self Assessment) e da abordagem intervencionista. A metodologia CSA estabelece a identificação dos riscos pelos gestores da área em análise, porém, nesse trabalho, com o intuito de se obter contribuição para a teoria, foram apurados dados referentes a todos os funcionários da área de RI. Posteriormente ao levantamento de dados, as implementações das ações corretivas necessárias foram discutidas e negociadas junto ao gerente da área. O resultado apurado demonstrou sucesso no processo de implementação, destacando que a participação de todos os funcionários da área para apuração de fragilidades é benéfica e salutar para o negócio. O principal ganho verificado foi a disseminação da cultura de riscos entre os participantes deste trabalho e uma melhoria no ambiente de controle para a empresa. Os resultados devem ser analisados considerando-se as limitações deste trabalho, que estudou uma empresa em um setor específico. Para tanto, como sugestão de pesquisas futuras, há a necessidade de se ampliar o número de empresas e áreas internas a serem estudadas, comparando-se as conclusões com as do presente trabalho.

Yes / This chapter encapsulates the multi-disciplinary nature that facilitates NLP in AI and reports on a linguistically orientated conversational software agent (CSA) (Panesar 2017) framework sensitive to natural language processing (NLP), language in the agent environment. We present a novel computational approach of using the functional linguistic theory of Role and Reference Grammar (RRG) as the linguistic engine. Viewing language as action, utterances change the state of the world, and hence speakers and hearer’s mental state change as a result of these utterances. The plan-based method of discourse management (DM) using the BDI model architecture is deployed, to support a greater complexity of conversation. This CSA investigates the integration, intersection and interface of the language, knowledge, speech act constructions (SAC) as a grammatical object, and the sub-model of BDI and DM for NLP. We present an investigation into the intersection and interface between our linguistic and knowledge (belief base) models for both dialogue management and planning. The architecture has three-phase models: (1) a linguistic model based on RRG; (2) Agent Cognitive Model (ACM) with (a) knowledge representation model employing conceptual graphs (CGs) serialised to Resource Description Framework (RDF); (b) a planning model underpinned by BDI concepts and intentionality and rational interaction; and (3) a dialogue model employing common ground. Use of RRG as a linguistic engine for the CSA was successful. We identify the complexity of the semantic gap of internal representations with details of a conceptual bridging solution.

For repairing concrete transportation infrastructure, such as pavements and bridges, much importance is placed on early-age strength gain as this has a major impact on scheduling and opening to traffic. However, the long-term performance and durability of such repair materials are often not satisfactory, thus resulting in future repairs. This research project focuses on the evaluation of the durability of various rapid-setting cementitious materials. The binders studied in this project include calcium aluminate cement (CAC), calcium sulfoaluminate cement (CSA), Type III portland cement, alkali-activated fly ash (AAFA) , and various prepackaged concrete materials. In addition, selected CAC and CSA mixtures were further modified with the use of a styrene-butadiene latex. The durability aspects studied include freezing-and-thawing damage and the implications of air entrainment in these systems, alkali-silica reaction, sulfate attack, and permeability of the concrete matrix and potential corrosion. / text

Responsible design practice should include environmental advocacy and a focus on community — subjects often lacking in design education. My creative project is the result of investigations into how designers integrate nature into their design process. By increasing their awareness for communal and environmental advocacy at the undergraduate level, students can develop responsible design practices at the beginning of their career. The result is the student's accumulation of integrity.

Master of Science / Department of Civil Engineering / Kyle Riding / Concrete is most widely used material in construction industry, which is made up of cement, water and aggregates as its major ingredients. Aggregates contribute to 60 to 75 % of the total volume of concrete. The aggregates play a key role in the concrete durability. The U.S Midwest has many aggregates that can show distress in the field under freezing and thawing conditions. The objective of this research was to determine if the Test Method for the Resistance of Unconfined Coarse Aggregate to Freezing and Thawing, method CSA A23.2-24A, could be used to differentiate good from poor performing aggregates in concrete. In this study fifty one KDOT aggregates (including twelve ledge and thirty nine production samples) were tested for freeze thaw resistance using CSA A23.2-24A test method and were compared to the results of the standard KDOT aggregate qualification tests. In addition to performing the CSA test method using a 3% sodium chloride solution, a subset of the aggregates were tested using either a 3% magnesium chloride or calcium chloride solution to determine the effects of the salt type on the aggregate performance. No correlation was found between the CSA A23.2-24A test method results and the standard KDOT aggregate qualification tests. The results also indicated that the mass loss in the CSA A23.2-24A was similar for the aggregate sizes tested. The use of alternate salt solutions like MgCl2 and CaCl2 resulted in increased freeze thaw mass loss in limestone aggregates.

<p>Rapid development in CMOS technology has resulted in its suitability for the implementation of readout front-end systems in terms of high integration density, and low power consumption yet at the same time posing many challenges for analog circuits design like readout front-end. One of the significant challenges is the low noise design for high speed front-end systems, while at the same time minimizing the power consumption as much as possible.</p><p>A high speed, low noise, low power, and programmable readout front-end system is designed and implemented for an X-ray detector in CMOS 0.18 m technology in this thesis work. The front-end system has a peaking time of 10 ns, which is the highest speed ever reported in the published work. The front-end system is designed to achieve low noise in terms of ENC, and a low power consumption of 2.9 mW. The detector capacitance is the most dominating parameter to low noise, which in turn is directly related to the power consumption. In this thesis work an ENC of 435 electrons is achieved for a detector capacitance of 5 pF and an ENC of 320 electrons for a detector capacitance of 3 pF. Based on the comparison to related published work, a performance improvement of at least two times is achieved taking peaking time, power, ENC, and detector capacitance all into consideration. The output pulse after amplification has peak amplitude of 300 mV for a maximum injected charge of 40000 electrons from the detector.</p><p>The readout front-end system noise performance is strongly dependent on the input MOSFET type, size, and biasing. In this work a PMOS has been selected and optimized as the input device due to its smaller 1/f noise and high gain as compare to NMOS when biased at same currents. The architecture designed in this work consists of a folded cascode CSA with extra cascode in first stage, a pole-zero cancellation circuit to eliminate undershoot, a shaper amplifier, and integrators using Gm-C filter technique. All of these components are optimized for low power while meeting the noise requirements. The whole front-end system is programmed for peaking times of 10, 20, and 40 ns. The programmability is achieved by switching different capacitors and resistors values for all the poles and zeros in the front-end, and by switching parallel transconductance in the Gm-C filters. Finally fine tuning of all the capacitance, resistance, and transconductance values is done to achieve required performance.</p>
