Reinforced concrete structures strengthened with CFRP (ACI x FIB) - Recommendations for bending design criteria

abstract: This work deals with the evaluation of the design criteria and security check (Ultimate Limit State - ULS) of the American (ACI-440.2R, 2017) and European (FIB Model Code, 2010) standards of reinforced concrete structures strengthened with Carbon Fiber Reinforced Polymers (CFRP), by the technique of Externally Bonded Reinforcement (EBR). It is intended to evaluate if, for a given database of 64 experimental tests of beams and slabs, the obtained results respect the safety conditions according to the mentioned standards, to increase the efficiency of this reinforcement technique and to lead to the establishment of regulatory design criteria in Brazil. Results show a conservative match among experimental and theoretical values calculated according to the two guidelines and it is concluded that a future regulation in Brazil on this subject should be based on the FIB Model Code.

Sistem Pengatur Tegangan Otomatis : Analisa Peralihan Dengan Pengendali Tunggal Dan Kaskade

This journal describes the design and analysis of the response of a single controller and cascade direct current type of Automatic Voltage Regulator (AVR) system. The direct current AVR system is represented form of a transfer function. For single and cascade controllers, it is designed using a parallel architecture using MATLAB software with predetermined design criteria. The types of controllers used consist of Proportional Differential (PD), Proportional Integral (PI), Proportional Integral Differential (PID), Proportional Differential with First Order Filters in the Differential Section (PDF) and Proportional Integral Differentials with First Order Filters in the Differential Section(PIDF). For the transition analysis, the observed parameters consist of rise time, peak time, steady state time, maximum pass value and peak value. The results of the analysis show that the controllers that meet the design criteria are Proportional Differential (PD) controllers and Proportional Differential controllers with First Order Filters in Differential Sections (PDF) for single controllers and cascade controllers. For a single controller, the value of the Proportional constant (Kp) is 0.6280 and the value of the Differential constant (KD) is 0.1710 for the Proportional Differential (PD) controller. Proportional constant value (Kp) is 0.6130, Differential constant value (KD) is 0.1710 and filter constant value (Tf) is 0.0009 for Proportional Differential controller with First Order Filter in Differential Section (PDF). Cascade controllers and Proportional Differential (PD) controllers, the Proportional constant (Kp) is 1.7300 and the Differential constant (KD) is 0.0242 for the inner circle (C2). Outer ring controller (C1), the proportional constant (Kp) is 179,000 and the Differential constant (KD) is 2.4600. Cascade controllers and Proportional Differential controller types with First Order Filters in the Differential Section (PDF), the Proportional constant (Kp) value is 1.5900, the Differential constant (KD) value is 0.0246, the filter constant value (Tf) is 0.0018 for the inner circumference (C2 ). For the outer ring controller (C1), the Proportional constant (Kp) value is 134,0000, the Differential constant (KD) value is 2.2900 and the filter constant value (Tf) is 0.00008.

Hospitales sustentables: partidas críticas para su construcción y el rol de la inspección técnica

Currently, the public health infrastructure in Chile, at its different scales, has made important advances in determining sustainability design criteria. However, it is possible to see that, during its construction, there are no standardized verification processes on sustainability aspects, and that the work of technical inspection focuses on the administrative compliance of construction contracts, rather than on checking technical aspects. This research proposes a list of critical items and activities to supervise hospital construction, to guarantee sustainable criteria in their operation. A survey was also made to professionals involved in the design, construction, and supervision of hospital construction, ranking the results with a multi-criteria methodology (AHP), which showed a preference in the thermal envelope (20%) and thermal and ventilation installations (17%). Finally, based on the weaknesses stated by the professionals, a control and monitoring process of these items and activities is proposed, redesigning the work of the Worksite’ Technical Inspector.

SOIL IMPROVEMENT METHODS USING MINIPILE FOR REDUCING SETTLEMENT VALUE IN HIGHWAY TOLL KERTOSONO – KEDIRI

A highway toll project is an urgent need in this modernization era, especially in our country, which currently has a population of around 250 million people. From the population that has been increasing, In the current era the need for transportation is also growing rapidly, Therefore, a safe and comfortable transportation is needed. Relationship with the occurred of soft soil in the STA. 18 + 000 to STA. 20 + 300, the authors need to provide an analyzing way of handling the soft soil in order to meet the criteria for the settlement criteria. Meanwhile, the purpose of making analysis soft soil improvement using minipile is to find out a technical point still meets the requirements stated in the design criteria. To achieve this goal, analysis of the soft soil improvement in carrying out the analysis and calculations was taken from the results analysis of the N-SPT value and laboratory testing material from the soil investigation of the borehole. The calculation results obtained are in the soil improvement methods at the location which was originally using a minipile it can reduce settlement value < 20 mm/years, safety factor in earthquake condition > 1.10 and time schedule for implementation pilling work on site 1 month faster than the time required when using another methods for each location that has of soft soil content, especially in the section STA. 18 + 000 to STA. 20 + 300.

Te Kēmu Hauora - Designing a mobile game to facilitate education and improve healthcare engagement

<p>This thesis addresses the research question “How could a mobile game be designed to facilitate education and improve healthcare engagement around skin sores in children?”. Health behaviour issues such as lack of education and low adherence to treatment regimes impact the success rates of treatments in children for common ailments such as skin sores. Skin sores are a particular health issue in New Zealand where the rates of admission to hospital for serious skin infections in 2006 were double that of USA and Australia (Craig et al., 2007, p. 278-282). Hospitalisation can be prevented by ensuring treatment regimes for skin sores are correctly completed after early diagnosis (Gray et al., 2013, p. 2). Literature states that game design is a viable solution to healthcare issues, as it can be used alongside persuasive strategies to engage and educate children around their treatments. However, there is a gap in the literature and existing precedents for health games addressing treatment of common ailments. This thesis addresses the research question through developing design criteria for a health game by identifying suitable theories to encourage positive health behaviors and educate children. These include: simulation, personalisation, reward and flow theory, as well as the information, motivation, strategy model to increase engagement with treatment. These criteria are used alongside user personas and journey maps methods to create the design output of a mobile health game to educate and engage New Zealand children around the treatment of skin sores. The game was tested for education, engagement and usability during the design process. Methods for user testing included observation, an adaption of the System Usability Scale and semi-structured interview questions. Thematic analysis of the testing results showed that most participants were engaged with the game and gained education around treatment steps. Insights on user testing with children for education, engagement, and usability are reported. The final output was refined and accessed against the design criteria. Findings from this thesis discuss how game design techniques including simulation, flow theory and reward can be used to educate and engage children with treatments of common ailments.</p>
