Water Stress Thresholds and Evaluation of Coefficient Ks for Perennial Ryegrass in Tropical Conditions
Authors: Terán-Chaves César Augusto , García-Prats Alberto , Polo-Murcia Sonia Mercedes
Published: May 2022

Perennial ryegrass (Lolium perenne) is the predominant forage crop in the equatorial highland zones of Colombia due to its high nutritional value and versatility to produce both milk and meat. This study aimed to determine the relationship between the relative depletion of usable soil water and the Ks values of canopy expansion and closure stomatal of perennial ryegrass, as well as to identify the threshold values of water stress. The experiment was carried out in pots under a controlled environment condition. These pots were arranged in a completely randomized manner. The experiment consisted of five treatments—including control treatment—of water deficits in the soil that progressively increased the depletion level as the crop cycle developed. This generated a wide range of conditions in the growth stages. For each treatment, four repetitions were performed Biomass production was significantly affected by water stress. The results show that the upper and lower thresholds of Ks were 0.28 and 1.3 of the depletion level (p) of the total available water (TAW) in the soil for the expansion of the canopy (CE), and 0.25 and 1.1 p of the TAW for stomatal closure (gs). Quadratic functions were fitted for both the CE (R2 = 0.72) and CS (R2 = 0.73); moreover, the Ks function of FAO-AquaCrop with positive shape factor (sf) was as follows: sf = 11, RMSE 0.22 for CE, and sf = 4.3, RMSE 0.19 for gs. Our results indicate that ryegrass is moderately sensitive to water stress. The differences found between the Ks function of FAO and the experimental data call for the need to use modeling with parameters adapted for each case.

Published: May 2022

This study aims to develop the intensity–duration–frequency (IDF) curves for Yangon, the economic center of Myanmar, using four satellite precipitation datasets, namely GPM IMERG, TRMM, GSMaP_NRT, and GSMaP_GC. Different probability distribution functions were used to fit the annual rainfall maximum series to determine the best-fit distribution. The estimated parameters of the best-fit distribution were used to fit the rainfall intensities of 2, 5, 10, 25, 50, and 100-year return periods for generating IDF curves using the Sherman equation. The IDF curves were bias-corrected based on the daily rainfall data available only at a location in Yangon. The bias correction factors were then used to estimate IDF curves from satellite rainfall at ungauged locations of Yangon. The results showed that the Generalized Extreme Value Distribution best fit the hourly rainfall distribution of satellite data. Integrated Multi-Satellite Retrievals for Global Precipitation Measurement (IMERG) is the most suitable for constructing Yangon’s IDF curves. The bias-corrected IDF curve generated at four locations of greater Yangon indicates higher rainfall intensity at the coastal stations than the inland stations. The methodology presented in this study can be used to derive IDF curves for any location in Myanmar.

Published: May 2022

Under extreme drought and climate change, golden pear trees have experienced problems such as yield reduction, dryness and death. This suggests that we know very little about the mechanisms regulating pear tree growth, assuming that meteorological factors positively influence plant sap flow. Based on this, we used the heat ratio method to monitor the sap flow of pear trees from June to December 2020, and recorded the changes in various environmental factors. The results showed that: (1) Sap flow velocity has obvious radial variability in tree sections; the sap flow velocity during the day was significantly higher than that at night (p < 0.05) and was higher in the growing season than in the non-growing season. (2) All environmental factors, except relative humidity and precipitation, were positively correlated with sap flow, vapor pressure deficit and photosynthetically active radiation, which are the key factors affecting daytime flow, and vapor pressure deficit and plant water potential are the key factors affecting nighttime flow. The linear regression results also showed that the daytime sap flow had a significant positive effect on the nighttime sap flow (p < 0.05). (3) The contribution of night flow to total daily flow varied from 17.3% to 50.7%, and most of the non-growing season values were above 40%. The results show that nighttime sap flow accounts for a significant portion of the pear tree’s water budget. Continuous irrigation during fruit enlargement and non-growing seasons will increase fruit yield and maintain plant sap flow activity to avoid death due to drought.
Wastewater System Inflow/Infiltration and Residential Pluvial Flood Damage Mitigation in Canada
Authors: Sandink Dan , Robinson Barbara
Published: May 2022

Pluvial flooding in urban areas is one of the most significant drivers of disaster loss in Canada. Damages during pluvial flood events are associated with overwhelmed urban drainage (stormwater and wastewater) systems. During the period from 2013 to 2021, Canadian property and casualty insurers reported approximately CAD 2 billion in personal property (residential) pluvial sewer backup claims during flood catastrophes. There has been growing interest in managing pluvial urban flood risk, notably through newly funded national programs focused on climate change adaptation. These programs have included the development of new guidelines and standards focused on managing the underlying factors contributing to urban and basement flooding. Inflow and infiltration (I/I) has received limited attention in the pluvial flood literature, however. Informed by significant engagement with practitioners in Canada, this paper provides a review of the issue of I/I into wastewater systems and its relation to pluvial flooding. The paper will address concerns related to private property engagement in I/I and urban pluvial flood reduction programs. Both improved technical standards and administrative support are needed to ensure that wastewater infrastructure is less susceptible to I/I over its lifecycle.

Published: May 2022

Water managers have increasingly shown that demand management solutions are more important than searching for alternative sources to resolve the challenges and shortages of water supply services. This study identifies the impact of climate variables on residential water demand in three geographically and spatially dispersed towns (Arba Minch, Ziway, and Debre Birhan) in Ethiopia. Monthly mean temperature, relative humidity, and precipitation are analyzed using multivariate regression models to identify and evaluate the impacts of the parameters on water consumption. Principal component analysis (PCA) is also used to determine the dominant independent variable affecting the rate of water consumption. Mean temperature is shown to be the dominant variable causing the changes in water consumption in Arba Minch. The water consumption at Debre Birhan is slightly affected by relative humidity. Analyzed climate variables do not affect the water consumption changes at Ziway. The main findings of this paper show that geographical distribution and other determinants are more important determinants of residential water demand. It is concluded that the analyzed climate variables are not the dominant determinants which impact drinking water consumption at the study sites. Thus, it is recommended to include relevant information about the climate variables alongside other determinants in order to enhance the water management system in evaluating and auditing water usage.
Experimental Data and Modeling the Adsorption-Desorption and Mobility Behavior of Ciprofloxacin in Sandy Silt Soil
Authors: Zhao Pingping , Wu Yanqing , Yu Fei
Published: May 2022

The improved understanding of the behavior of antibiotics in soil is of great importance due to their environmental hazard and frequent detection. In this work, the adsorption-desorption and mobility behaviors of ciprofloxacin in sandy silt soil, affecting the fate of ciprofloxacin in the environment, were studied by a series of batch tests and column tests. In batch tests, the effects of contact time, initial ciprofloxacin concentration, sandy silt soil dosage, solution pH, and ionic strength on ciprofloxacin adsorption and desorption in sandy silt soil were considered. Adsorption results were satisfactorily modeled, with good fittings to the pseudo-second-order model (R2 > 0.999) and Langmuir model (R2 > 0.991), with the value for Langmuir’s maximum adsorption capacity (qm) 5.50 mg g−1. Ciprofloxacin adsorption decreased sharply by increasing the pH from 7.0 to 10.0 and the ionic strength from 0.01 to 0.2 mol L−1 CaCl2. Comparatively, ciprofloxacin was more readily desorbed from sandy silt soil at alkaline and high ionic strength conditions. Breakthrough curves of ciprofloxacin obtained from the column experiments were described by the two-site model, Thomas model, and Yan mode. Of these models, the two-site model was the most suitable to describe the mobility of ciprofloxacin. The retardation factor (R) obtained in the two-site model was 345, suggesting strong adsorption affinity with ciprofloxacin on the sandy silt soil surface. The results from the Thomas model suggested the extremely small external and internal diffusion resistances. The Yan model was not suitable. Cation exchange interaction, electrostatic interaction, mechanical resistance, entrapment between porous media, and gravity sedimentation were proposed to be the important adsorption mechanisms.
Analysis of ENSO-Driven Variability, and Long-Term Changes, of Extreme Precipitation Indices in Colombia, Using the Satellite Rainfall Estimates CHIRPS
Authors: Giraldo-Osorio Juan , Trujillo-Osorio David , Baez-Villanueva Oscar
Published: May 2022

Climate change includes the change of the long-term average values and the change of the tails of probability density functions, where the extreme events are located. However, obtaining average values are more straightforward than the high temporal resolution information necessary to catch the extreme events on those tails. Such information is difficult to get in areas lacking sufficient rain stations. Thanks to the development of Satellite Precipitation Estimates with a daily resolution, this problem has been overcome, so Extreme Precipitation Indices (EPI) can be calculated for the entire Colombian territory. However, Colombia is strongly affected by the ENSO (El Niño—Southern Oscillation) phenomenon. Therefore, it is pertinent to ask if the EPI’s long-term change due to climate change is more critical than the anomalies due to climate variability induced by the warm and cold phases of ENSO (El Niño and La Niña, respectively). In this work, we built EPI annual time series at each grid-point of the selected Satellite Precipitation Estimate (CHIRPSv2) over Colombia to answer the previous question. Then, the Mann-Whitney-Wilcoxon test was used to compare the samples drawn in each case (i.e., change tests due to both long-term and climatic variability). After performing the analyses, we realized that the importance of the change depends on the region analyzed and the considered EPI. However, some general conclusions became evident: during El Niño years (La Niña), EPI’s anomaly follows the general trend of reduction -drier conditions- (increase; -wetter conditions-) observed in Colombian annual precipitation amount, but only on the Pacific, the Caribbean, and the Andean region. In the Eastern plains of Colombia (Orinoquía and Amazonian region), EPI show a certain insensitivity to change due to climatic variability. On the other hand, EPI’s long-term changes in the Pacific, the Caribbean, and the Andean region are spatially scattered. Still, long-term changes in the eastern plains have a moderate spatial consistency with statistical significance.
A GPU-Based δ-Plus-SPH Model for Non-Newtonian Multiphase Flows
Authors: Shi Hao , Huang Yu
Published: May 2022

A multiphase extension of the δ-plus-SPH (smoothed particle hydrodynamics) model is developed for modeling non-Newtonian multiphase flow. A modified numerical diffusive term and special shifting treatment near the phase interface are introduced to the original δ-plus-SPH model to improve the accuracy and numerical stability of the weakly incompressible SPH model. The Herschel–Bulkley model is used to describe non-Newtonian fluids. A sub-particle term is added in the momentum equation based on a large eddy simulation. The graphic processing unit (GPU) acceleration technique is applied to increase the computational efficiency. Three test cases including, a static tank, Poiseuille flow, and submarine debris flow, are presented to assess the performance of the new multiphase SPH model. Comparisons with analytical solutions, experimental data, and previous numerical results indicate that the proposed SPH model can capture highly transient incompressible two-phase flows with consistent pressure across the interface.
Community-Scale Rural Drinking Water Supply Systems Based on Harvested Rainwater: A Case Study of Australia and Vietnam
Authors: Ross Tara T. , Alim Mohammad A. , Rahman Ataur
Published: May 2022

Rainwater harvesting (RWH) systems can be used to produce drinking water in rural communities, particularly in developing countries that lack a clean drinking water supply. Most previous research has focused on the application of RWH systems for individual urban households. This paper develops a yield-after-spillage water balance model (WBM) which can calculate the reliability, annual drinking water production (ADWP) and benefit–cost ratio (BCR) of a community-scale RWH system for rural drinking water supply. We consider multiple scenarios regarding community aspects, including 150–1000 users, 70–4800 kL rainwater storage, 20–50 L/capita/day (LCD) drinking water usage levels, local rainfall regimes and economic parameters of Australia (developed country) and Vietnam (developing country). The WBM analysis shows a strong correlation between water demand and water supply with 90% system reliability, which allows both Australian and Vietnamese systems to achieve the similar capability of ADWP and economic values of the produced drinking water. However, the cost of the Vietnamese system is higher due to the requirement of larger rainwater storage due to larger household size and lower rainfall in the dry season, which reduces the BCR compared to the Australian systems. It is found that the RWH systems can be feasibly implemented at the water price of 0.01 AUD/L for all the Vietnamese scenarios and for some Australian scenarios with drinking water demand over 6 kL/day.
Towards Sustainable Community Development through Renewable Energies in Kyrgyzstan: A Detailed Assessment and Outlook
Authors: Mehta Kedar , Ehrenwirth Mathias , Trinkl Christoph , Zörner Wilfried
Published: May 2022

In rural Kyrgyzstan, the energy need is usually derived from multiple natural energy resources such as firewood, charcoal, agricultural residues, animal dung, and wood branches, which are considered common and predominant practices. Because of the non-sustainable resources and heavy reliance on the environment, Kyrgyzstan is one of the most vulnerable countries to climate change in Central Asia. On the contrary, the great renewable energy potential in Kyrgyzstan is untapped, which could be the most promising solution to ensuring sustainable energy supply in the country. However, because of the lack of scientific knowledge, current energy policies, and the lack of infrastructure, renewable resources are mainly untapped. To exploit the country’s renewable energy potential, there is a need for a systematic diagnosis to develop a strategy to explore renewables in Kyrgyzstan, which is currently missing in the existing literature. In that regard, the presented study aims to assess the current status of renewable energy sources by considering the local energy context from a potential point of view. Further to this, it provides a comparative overview through a matrix of strengths, weaknesses, opportunities, and threats. Such novel analysis would be the fundamental base for formulating policy advice and a national plan to enhance the utilization of renewable energy in Kyrgyzstan. The presented analysis was carried out based on the extensive literature review, the country’s national plan, and the existing energy policies of Kyrgyzstan. The article found out that there is huge potential available for the renewable energy market. As compared to other renewable energy sources, solar energy has great potential and can be considered one of the pioneer sustainable sources for integration into the country’s power generation framework.

The main principles of sturgeon breeding in the USSR were developed in the works of A.N. Derzhavin, N.L. Gerbilsky, N.I. Kozhin, B.N. Kazansky, I.A. Barannikova, T.A. Detlaff and other ichthyologists. The so called “Soviet model of sturgeon breeding” relied on using of wild prespawning breeders selected from commercial catches in lower parts of rivers. After transportation to sturgeon hatchery sturgeons were injected by pituitary preparation. The ovulated eggs were inseminated, subjected to de-adhesion and incubated. One-day larvae were kept until the transition to exogenous nutrition and, after preliminary growing on live food in pools (combined method) or immediately (pond method) transferred to ponds. The average weight of fingerlings was 3 g. The modern “Russian model of sturgeon breeding” uses the formation of domestic broodstock because the hatchery releases cannot provide sufficient recruitment. The North American model of sturgeon breeding uses only “wild” breeders in prespawning or spawning state. The fingerlings are raised at sturgeon hatcheries to high weight, marked and released at age of 1 year, while the number of offspring of each female is limited. The survival rate of juveniles in nature depends on environmental condition and ecological capacity, so the optimal volume of releases is strictly calculated. The North American model of sturgeon breeding is used not only in the United States, but in the Danube basin, in the rivers of Turkey and in conservation programs for Chinese sturgeon of Yangtze River.

Musculoskeletal injuries as a kind of trauma that the human body is exposed to, adversely affect the quality of life and workforce of individuals due to restriction of movement function. This study aimed to evaluate the effects of dose-dependent ascorbic acid (AA) administration on the repair process after gastrocnemius muscle injury in rats. In this study, 5-month-old 66 male Wistar Albino rats were used and rats were randomly divided into 6 groups of 11 each [control, muscle injury, healthy (with 5 mg/10 mg/kg/day AA-treated group), injury (with 5 mg/10 mg/kg/day AA-treated group)]. A linear incision was made in the gastrocnemius muscle of thirty-three animals included in the muscle injury groups. AA (5-10 mg/kg/day) was administered to the four groups intraperitoneally just after surgery once a day. Animals were sacrificed twenty-one days later. Blood and tissue samples were used for cytokine, collagen, and histological measurements. It was found that a dose of 5 mg/kg/day AA administration reduced serum IL-6 and muscle tissue TNF-α levels, and increased liver tissue IL-10 levels. Muscle tissue collagen levels were not statistically different between the groups in parallel with our histological results. In our study, it was demonstrated that vitamin C has effects on inflammatory mediators during muscle tissue repair to explain the mechanism detailed molecular analyzes are needed.
Natural Navigation System Design for Indoor Mobile Robots

Published: May 2022

Natural navigation simply refers to free navigation without the necessity of tapes, magnets, reflectors, or even wires. Many autonomous vehicles possess this as world maps are readily available and provide a perfect basis for machine learning solutions. However, this is not so much the case for indoor applications. Here, paths are often dynamic and more constrained; therefore, requiring the continuous identification, mapping and localization of the surrounding area. This work focuses on developing an indoor natural navigation system; the localization is achieved with a fusion of the wheel’s odometry to the on-board Inertial Measurement Unit (IMU i.e., a combination of relative localization and absolute localization) using Unscented Kalman Filter (UKF) as system’s encoder’s accumulation of errors is desired to be nullified while employing a PID control in correcting reference state errors. The map is simultaneously constructed using laws of geometry based on static points obtained from a Lidar, subsequently converted to an occupancy grid layout for effective path planning. In operation, tangency is applied in the avoidance of dynamic obstacles. The simulation results obtained in this study confirms the possibility of a simple, educational, indoor navigation system approach easily integrable by other mobile robots of the differential drive model.
Statistical Evaluation of Water Quality and Meteorological Conditions in Karacaören-II Dam Lake
Authors: YENİLMEZ Firdes
Published: May 2022

Karacaören-II Dam Lake is located on Aksu Stream within the borders of Burdur. The lake is planned to be a drinking water supply for Antalya in the near future. Some scientific studies carried out in recent years stated that the lake suffers from eutrophication problem due to the pressures within the basin.

This study examined the relationships between the selected water quality parameters (BOD5, DO, pH, NH4-N, NO2-N, NO3-N, TKN, TN, o-PO4, TP and TSS) and the meteorological parameters (temperature, wind speed, precipitation, humidity, pressure, vaporization) measured between the years 2005 and 2014 using correlation analysis. The main factors contributing to the variation in the data set were also determined by principal component analysis and the trends in selected water quality parameters were analyzed using the Mann-Kendall test. The statistical tests indicated that nitrogen, phosphorus, pH, temperature, precipitation, and vaporization are the major parameters influencing the water quality in the dam lake. A very high correlation is found between NO3-N and DO. Trend analysis showed an upward trend in TN and TP concentrations. The results of this study will be beneficial to decision-makers for better management of water quality and to those who will carry out studies on the lake in the future.

In the context of developing the Sabang Free Trade Zone and Free Port, it is necessary to revitalize the development of the Balohan Crossing Port of Sabang City. However, based on Article 11 PP Number 69 of 2001 concerning Ports, it is stated that the management of national, international ports and hub ports is left to BUMN, in this case PT. Indonesian Port (Pelindo). Whereas on the other hand, Law No. 32 of 2004 and Law No. 34 of 1999 indicates the transfer of authority from the central government to regional governments, including in terms of port management. The same is true in the context of Aceh's autonomy, based on Law No. 11 of 2006 concerning the Government of Aceh states that there is a surrender of wider authority to the regions to manage their own household affairs. The problem in this research is how is the authority to operate a port based on positive law in Indonesia? What is the authority for managing regional feeder ports in the context of Aceh's special autonomy? And what are the procedures for the utilization and management of the Balohan crossing port? The method used in this study is a nominative juridical research method. The results of the study showed that the authority to operate the port was technically regulated in Government Regulation No. 61 of 2009 concerning Ports. In the context of Aceh's special autonomy, Law No. 11 of 2006 concerning Aceh Government and PP No. 23 of 2015 concerning National Government Authority in Aceh in the context of Aceh's special autonomy, wasn’t mentioned in detail regarding port management according to the type of hierarchy, but only mentioned regarding port management (in general) managed by BUMN in which the management is managed with the Aceh Government and / or Regency / City Government. Even though the Act and PP aren’t mentioned in detail, the procedures for the utilization and management of the Balohan crossing port can be seen in the Minister of Transportation Decree Number KP. 432 of 2017 concerning the Establishment of a National Port Master Plan. The Ministry of Transportation stated that the Port of Balohan Sabang occupied the PL (Local Feed Port) hierarchy. This means that the Regency / City Government in Prov. Aceh has the authority to manage the Balohan Port in Sabang legally justified and allowed by law.Keywords: authority, management and development, balohan port

Article 44 of the KuHP states that: "Confiscated objects are stored in state confiscation houses. In Article 1 number 3 of Government Regulation No. 27 of 1983 on the Implementation of Criminal Events Act also mentions that the State Confiscation House is hereby called RUPBASAN is the place of objects confiscated by the State for the purposes of judicial proceedings. RUPBASAN is where objects confiscated by the State for the purposes of judicial proceedings. RUPBASAN is established in every capital city or city district, and if necessary can be established RUPBASAN Branch. However, in practice not all district capitals or cities have RUPBASAN to manage confiscated objects and loot proceeds from crimes, so the management of the proceeds of crime is under direct management by the law enforcement agencies that handle such crimes. Based on the background as described above, the formulation of the problems in this study is: what are the arrangements regarding the management of Confiscated Objects in the RUPBASAN? And how is the management of Confiscated Goods and Proceeds of Looting Crimes in Indonesia? This research is a normative juridical study, namely research conducted by examining library materials or secondary data. The results showed the amount of assets or items seized from the defendant in criminal cases by law enforcement officers that were still not properly managed, meaning they had been confiscated or taken from the defendant, but were not properly managed. So far there has been an institution called RUPBASAN, as stipulated in Law No. 8 of 1981 on KUHAP, PP No. 27/1983 on The Implementation of KUHAP, and Regulation of the Minister of Justice Number: M.05.UM.01.06 of 1983 on the Management of Confiscated Goods and State Booty in the State Confiscation House, but not utilized properly. Confiscated items are all stored in the police station or prosecutor's office, whereas if stored and left unmanaged properly then there will be a decrease in value.

Severe Hematologic Manifestations Among Filipino Patients With Systemic Lupus Erythematosus: a 5-Year Retrospective Cohort Study
Authors: Navarroza Rodeo V , Navarra Sandra V
Published: May 2022

Objective: Determination of the prevalence of severe hematologic manifestations among Filipino patients with systemic lupus erythematosus (SLE) and analysis of any association with organ involvement and serology. Methods: This cross-sectional study included SLE patients 19 years old and above seen at the UST Hospital from 2012 to 2017. Patients with severe hematologic manifestations (severe hemolytic anemia, severe thrombocytopenia, and ES[ES]) were identified and their prevalence determined. Independent t-test was used to compare continuous variables. Categorical variables were measured using the chi-square test; odds ratios (OR) with their corresponding 95% confidence interval were calculated using the SPSS software version 21. This study has been approved by the Institutional Review Board. Results: Of the 253 patients (238 females, 94.07%), the mean age at diagnosis was 27.04 (SD 9.96) years. Severe hematologic involvement was noted in 12.26% (n=31); severe hemolytic anemia was the most prevalent (14, 5.53%), followed by severe thrombocytopenia (13, 5.14%) and ES (4, 1.58%). Higher prevalence of major organ involvement was observed among patients who manifest with severe hematologic disease. Severe thrombocytopenia was more likely to have cardiac involvement (OR 7.39, 95% CI 1.90 to 28.81, p=0.004). A higher prevalence of negative baseline anti-dsDNA serology was seen among patients who developed ES. Conclusion: Severe hematologic involvement was noted in 12.26% of Filipino SLE patients, with hemolytic anemia as the most frequently recorded.

The issue of a university teacher’s professional career is considered. The relevance of the study is determined by the fact that the chosen subject is actively developed by supporters of the personality-activity theory, which underlies the design of the educational process in the substantive and methodological aspects. The notion of “career-forming education” (CFE) is interpreted as a non-situational amount of knowledge, applied skills and cognitive scenarios aimed at achieving high results in the profession (recognition within the community, well-paid and socially significant positions) and receiving positive emotions from the work. We understand the system of career growth as a subsystem that is a part of professional education. When studying this system, the authors of the article used the concept of Russian professional education proposed. According to this concept, there are four main ideas: the humanization of education, its democratization and an emphasis on continuity and being ahead of the time. The novelty of the study and its theoretical and practical significance consists in defining three conditions favouring the university teacher’s career growth: the integration of pedagogical work into the system of life meanings and the value hierarchy of the person as their most important component; constant creative search with a critical attitude to one’s professional level; the teacher’s readiness to implement innovative activities. Conditions for the university teacher’s professional development are the following: integration of pedagogical work into the system of life meanings; constant creative search; readiness for the implementation of innovative activities.

A strain-insensitive high-sensitivity temperature sensor based on multimode interference in a specialty fiber with a square core is developed and experimentally investigated. A 25 cm long square-core fiber is used as a multimode fiber (MMF) of a single-mode–multimode–single-mode structure and the temperature dependence of its transmitted spectrum is measured while the strain is applied continually from 0 to 500 με with steps of 100 με. The mean temperature sensitivity is −22.35 pm °C−1, which is ∼3.5 times higher than that of a standard MMF, and it is almost independent of strain with a small standard deviation of 0.44 pm °C−1.

An experimental work is performed in a constant volume combustion chamber to study the effect of varying hot surface temperature on ignition delay characteristics for different fuel sprays (Hollow cone spray and Solid cone spray). For ejecting the sprays pintle and single hole nozzles were used. In this experimental work hot surface temperature (HST) varied from 350°C to 550°C, air pressure inside the cylinder varied from 10 to 25 bar while fuel injection pressures varied from 10 to 20 MPa. Optical method is used for detecting the flame appearance while a digital Oscilloscope is used to measure ID of sprays by recording the gap between injection event and the event of appearance of flame. During the work it is found that ID is strong function of HST rather than other operating parameters. It is also found that on increasing HST, for both sprays ignition delay is decreasing at every injection pressures.

Computable Artificial General Intelligence
Authors: Bennett Michael Timothy
Published: May 2022

An artificial general intelligence (AGI), by one definition, is an agent that requires less information than any other to make an accurate prediction. It is arguable that the general reinforcement learning agent AIXI not only met this definition, but was the only mathematical formalism to do so. Though a significant result, AIXI was incomputable and its performance subjective. This paper proposes an alternative formalism of AGI which overcomes both problems. Formal proof of its performance is given, along with a simple implementation and experimental results that support these claims.

Published: May 2022

The paper presents a new method for experimental studies of typical prototypes with triple modal reservation. The authors propose to define the investigated devices in the frequency domain and then by using Advanced Design System software to redefine their characteristics in the time domain. The paper contains recommendations for the preparation and conduction of such experimental studies. Using these recommendations, the authors conducted measurements of the complex S-parameters of the circuits with triple modal reservation in the frequency range from 10 MHz to 18 GHz before and after failures. Then, to analyze the response to ultra-wideband interference, a pulse in the trapezoidal waveform with a duration of 150 ps was excited in Advanced Design System to the input of the reserved circuit. The maximum amplitude value at the end of the reserved circuit is obtained for all the faults studied. The authors also present the optimal order of switching the reserving circuits. This paper proposes the methods for analyzing the frequency and time characteristics. It makes possible to analyze the characteristics of circuits with multiple modal reservation and to determine the optimal switching order for reserving circuits. The proposed method requires commonly used equipment and a minimum set of technical tools that can reduce economic expenditures and time costs.

Self-driving laboratories receive increasing acceptance as they are used in research and education. For research, they mainly serve as a platform on which algorithms can be tested under realistic conditions before getting deployed into the real world. In education, they can add value by creating a reference to reality as they o er an application for theoretical knowledge. In combination with the fact that practical work is well appreciated among students, such setup helps to motivate and thus enhance the learning experience. However, not every institution has the capabilities to create a self-driving lab on its own. Instead, open-source and remotely accessible laboratories, like our Cyber-Physical Mobility Lab (CPM Lab) can be used to engage with the domain of networked and autonomous vehicles. By means of two of our courses, we demonstrate the capabilities of the CPM Lab. These two courses can either be used as groundwork to develop own lectures in this domain, or used directly since the course materials are open-source.

Published: May 2022

In this paper, we bring forward the use of the recently developed Signature Transform as a way to measure the similarity between image distributions and provide detailed acquaintance and extensive evaluations. We are the first to pioneer RMSE and MAE Signature, along with log-signature as an alternative to measure GAN convergence, a problem that has been extensively studied. We are also forerunners to introduce analytical measures based on statistics to study the goodness of fit of the GAN sample distribution that are both efficient and effective. Current GAN measures involve lots of computation normally done at the GPU and are very time consuming. In contrast, we diminish the computation time to the order of seconds and computation is done at the CPU achieving the same level of goodness. Lastly, a PCA adaptive t-SNE approach, which is novel in this context, is also proposed for data visualization.
