Urban revitalisation with music and dance in the Port of Veracruz, Mexico
Authors: Gutiérrez H. Fernando , Törmä Ilkka 
Published: February 2020

AbstractThe paper portrays thePlazuela de la Campana, a historical small square in the Port of Veracruz, Mexico that fell into ill-use and was revived with a strategy of music and dance events. The case demonstrates how music and dance became a new tradition that nurtures a collective attachment to the Plazuela and contributes to it being regarded as heritage. The privately initiated revitalisation borrows potency from prior nostalgic memories and traditions to overpower the past notoriety of the square. Dance and music, besides creating pleasant associations, effectively build a network of friendships that engages people in the square and through which the history of the place becomes remembered. All these effects deepen the meaningfulness of the Plazuela, which fosters personal affection towards the square and ultimately, it is proposed, translates into a general appreciation—a lesson to be learned for emerging urban planning practices.
Applying semantic gravity wave profiles to develop undergraduate students’ academic literacy
Authors: Brooke Mark 
Published: February 2020

Abstract
This study draws on Legitimation Code Theory (LCT), particularly semantic gravity waving, as a strategy for
academic literacies practitioners to conceptualise how knowledge in their field might be organised and presented. Students can be
guided to notice meanings related to context-dependency at the discourse and lexico-grammatical levels through the presentation of
semantic gravity waving profiles. For this study, semantic gravity waving profiles have been found useful for explaining the
rationale of a genre pedagogy approach, the structure of an Introduction-Method-Results-Discussion (IMRD) genre, and teaching both
lexical coherence for a theoretical framework section, and accurate use of determiners with non-count abstract nouns such as
“research”. Therefore, semantic gravity profiling seems to provide explanatory power as a pedagogical tool in the classroom.
Findings from a mixed method survey with sixty students as well as extracts from student texts before and after semantic gravity
waving profile pedagogical interventions are provided.

Published: February 2020

AbstractThere is scarcity of research examining the physiological and psychological effects of ultra‐endurance racing on athletes in extreme conditions. The purpose of the current study was to identify common injury patterns and illness, profile mood states and sleep patterns and finally examine the relationships between mental toughness, sleep, mood and injury rates during a 120 mile, three‐day Arctic ultra‐marathon. Twelve participants (3 females, 9 males) with a mean age of 42 ± 5.35 yrs participated in the study. Mental toughness was measured using the MT18 questionnaire. Injuries were clinically assessed and recorded each day. Temperatures ranged from −20 to −6 degrees Celsius throughout the race. Sleep quantity and mood state were recorded using the BRUMS questionnaire. 10 out of the 12 participants experienced injuries; almost half of the participants had injuries that carried over a number of days. Mean sleep duration over the three days was 4.07 h, with an average of 0.78 injuries per day. Significant changes in mood were recorded across the three days, specifically a reduction in vigour (p = .029) and increase in fatigue (p = .014). Neither sleep quantity nor mental toughness was correlated with injury rate. Interestingly, sleep quantity was not related to changes in mood, as previously shown in ultra‐marathons. Mental toughness had a moderate negative correlation (p < 0.01) with depression (−.623), reduced anger (−.616), confusion (−.558), increased vigour (.497) and tension (−.420) during the race. Success in this type of event involves significant psychological and physiological preparation to minimize the effects of sleep deprivation and avoidance of injuries.
Characterisation of a deep-ultraviolet light-emitting diode emission pattern via fluorescence
Authors: McFarlane Mollie , McConnell Gail 
Published: February 2020

Abstract
Recent advances in LED technology have allowed the development of high-brightness deep-UV LEDs with potential applications in water purification, gas sensing and as excitation sources in fluorescence microscopy. The emission pattern of an LED is the angular distribution of emission intensity and can be mathematically modelled or measured using a camera, although a general model is difficult to obtain and most CMOS and CCD cameras have low sensitivity in the deep-UV. We report a fluorescence-based method to determine the emission pattern of a deep-UV LED, achieved by converting 280 nm radiation into visible light via fluorescence such that it can be detected by a standard CMOS camera. We find that the emission pattern of the LED is consistent with the Lambertian trend typically obtained in planar LED packages to an accuracy of 99.6%. We also demonstrate the ability of the technique to distinguish between LED packaging types.
A review of flexibility of residential electricity demand as climate solution in four EU countries
Authors: Mata Érika , Ottosson Jonas , Nilsson Johanna 
Published: February 2020

Abstract
Increased flexibility at the grid edge is required to achieve ambitious climate goals and can be provided by smart energy solutions. By systematically reviewing the literature, we provide an overview of the potential flexibility of different residential electrical loads for France, Germany, Sweden, and the United Kingdom. While 85% of the studies aimed to identify potentials for shifting electrical energy use in time, the other 15% aimed to identify energy-saving potentials. Most of the data were found for the German and British electrical systems. A wide range of flexibility measures (e.g. price mechanisms, user-centered control strategies for space heating and water heating, automated shifting of appliances’ use, EV charging algorithms, and consumer feedback) and methods (e.g. simulations, trials, and interviews) have been used. Potentials obtained from the literature have been upscaled to the national level, including corresponding effects in terms of carbon dioxide (CO2) emissions. The results show that between 2% and 18% of residential sector electricity in the four countries could be shifted, resulting in total emission reductions of 10 MtCO2 from peak shaving, or 24 MtCO2 per year if optimizing the deployment of renewables. The literature identifies substantial economic, technical, and behavioral benefits from implementing flexibility measures. In all the cases, it seems that the current regulatory framework would need to change to facilitate participation. Recognized risks include higher peaks and congestions in low price-hours and difficulties in designing electricity tariffs because of conflicts with CO2 intensity as well as potential instability in the entire electricity system caused by tariffs coupling to wholesale electricity pricing.
Research on blackout simulation model considering hidden failures and reclosing
Authors: Qingqing HAO , Qun YU 
Published: February 2020

Abstract
In this paper, a blackout simulation model considering hidden failures and reclosing is proposed, which is more realistic than the previous model. The operation of reclosing devices, the synchronization control for reclosing in two-ended sources transmission lines and the interaction between reclosing and relay protection are simplified. Simulation results of IEEE39-bus test system are obtained to confirm the validity of the model. Compared with the blackout simulation model considering only the hidden failures of relay protection, it shows that the trip caused by the transient faults and hidden failures induced by transient faults can be corrected in this large-scale blackout simulation model. It also shows that with the increase of the probability of hidden failure, the failure rate of reclosing becomes an important factor affecting the system recovery.
Temperature extraction method for infrared image of high voltage power equipment
Authors: Xueyou HUANG , Yu ZHANG , Xianan JIAO , Shuheng MA , Jun XIONG 
Published: February 2020

Abstract
An infrared temperature prediction method for power equipment is proposed based on the radial basis function (RBF) network optimized by quantum genetic algorithm (QGA) and orthogonal least squares algorithm (OLSA). The modified compound algorithm was used to optimize parameters of the RBF network. A temperature prediction model was established through the fitting of pixels and temperatures of the infrared image of an equipment. After image matching, the infrared temperature at a position can be directly obtained from the visible image. Meanwhile, we can also directly read temperature values of different positions from the infrared image and identify the corresponding positions in the visible image. Experimental results indicate that the algorithm proposed has a better prediction performance than the RBF network optimized by OLSA alone and by adaptive genetic algorithm (AGA) and OLSA. It improves the generalization capacity of RBF network, resulting a more stable input and a higher prediction accuracy. The algorithm proposed facilitates temperature analysis and condition-based maintenance for substations.

Comparison of fuel consumption and emission characteristics of china VI coach under different test cycle
Authors: Yu Hanzhengnan , Liu Yu , Li Jingyuan 
Published: February 2020

Abstract
As the test cycle used for evaluating the fuel consumption and emission characteristics of the heavy-duty commercial vehicle in China will be replaced from C-WTVC to CHTC in a round 2020, the investigation on the variation of fuel consumption and emission test results after the replacement is well needed for further vehicle’s development and calibration. In this paper, the fuel consumption and emission characteristics of a China VI coach under these two test cycles have been discussed and compared. Results showed that fuel consumption, CO, HC and NOx emissions of the test coach all increased after changing the test cycle from C-WTVC to CHTC, which were due to the low rotation speed and low torque operating points, and the aggressive and frequent acceleration under CHTC. In addition, Acceleration driving condition contributed most to the deterioration of fuel consumption, CO, HC and NOx emissions under CHTC, which attention should be especially paid in the further vehicle calibration.

Growth performances of Nile Tilapia, Oreochromis niloticus, reared in recirculating aquaculture and active suspension systems
Authors: Amin M , Musdalifah L , Ali M 
Published: February 2020

Abstract
Recirculating aquaculture system (RAS) and active suspension aquaculture system (ASS) are rearing systems which are commonly used in aquaculture productions nowadays. This study aimed at comparing the growth performances of Nile tilapia cultured at the two aquaculture systems for 42 days. The measured parameters were growth rate, weight gain, feed conversion ratio, survival rate, and nutrient utilization (protein efficiency ratio, fat efficiency ratio, and energy efficiency ratio). The results showed that Tilapia reared in the RAS had significantly higher growth rate, weight gain, lower feed conversion ratio, and more efficiently in the utilization of protein, fat, and energy compared to tilapia reared in ASS. These results may indicate that the recirculating aquaculture system provided more comfortable environments for the tilapia for growth compared to the active suspension aquaculture system. However, another study in terms of economic perspective is still required, since the recirculating aquaculture system requires more rearing tanks and operational costs, especially from electricity.
