Data-Driven Solutions and Discoveries in Mechanics Using Physics Informed Neural Network

Deep learning has achieved remarkable success in diverse computer science applications, however, its use in other traditional engineering fields has emerged only recently. In this project, we solved several mechanics problems governed by differential equations, using physics informed neural networks (PINN). The PINN embeds the differential equations into the loss of the neural network using automatic differentiation. We present our developments in the context of solving two main classes of problems: data-driven solutions and data-driven discoveries, and we compare the results with either analytical solutions or numerical solutions using the finite element method. The remarkable achievements of the PINN model shown in this report suggest the bright prospect of the physics-informed surrogate models that are fully differentiable with respect to all input coordinates and free parameters. More broadly, this study shows that PINN provides an attractive alternative to solve traditional engineering problems.
Control Of Single-Phase Grid-Connected Inverters For Voltage Regulation With Non-Linear Loads: A Review

This work is about the development of renewable energy sources. In this project we are going to present the working simulation model of a solar panel using SIMULINK in MATLAB. The main objective is the combined application of renewable energy concepts and control systems for the qualitative and quantitative improvement of the electricity generated from solar and wind sources. The energy generated from the common sources of solar and wind power is generally at some level. But the integration of solar and wind sources and control systems will certainly be greater in quantity and the use of electronic power converters will make the energy generated more efficient. By synchronizing this generated energy with the smart grid, both the consumer and the producer will benefit from it and be satisfied.
Late Holocene Moisture Changes in the Core Area of Arid Central Asia Reflected by Rock Magnetic Records of Glacier Lake Kalakuli Sediments in the Westernmost Tibetan Plateau and their Influences on the Evolution of Ancient Silk Road

The evolution of Ancient Silk Road (ASR) was deeply influenced by late Holocene moisture changes in Arid Central Asia (ACA). Nevertheless, controversies in Holocene moisture change pattern of ACA and poorly–constrained age models of related studies have made the discussion about late Holocene moisture changes in ACA and their influences on the evolution of ASR difficult. Recently, a high–resolution age model during the late Holocene was established for Kalakuli Lake, a small glacier lake located in the core area of ACA. A thorough rock magnetic investigation was carried out on Kalakuli Lake sediments based on this age model. The magnetic mineral assemblage of Kalakuli Lake sediments is still dominated by primary magnetite despite minor diagenetic effects. Comparisons of rock magnetic records to parameters previously used as indicator of glacier fluctuations suggest that clastic input to Kalakuli Lake was high (low) and magnetic grain size is relatively larger (smaller), when glaciers on Muztagh Ata advanced (retreated). The ARM/SIRM ratio, a magnetic grain size proxy, is directly related to lake hydrodynamics, which are ultimately controlled by glacier fluctuations on Muztagh Ata as the result of regional moisture changes. Late Holocene moisture changes indicated by the ARM/SIRM ratio are consistent with cool/wet and warm/dry oscillations indicated by the unweighted average of biomarker hydrogen isotopic data of the C26 and C28 n–alkanoic acids in a previous study about Kalakuli Lake, most moisture change records of the core area of ACA and winter insolation of the Northern Hemisphere, but opposite to Asian monsoon evolution. Given Asian monsoon and the westerlies are mutually inhibited, we propose that late Holocene moisture changes in the core area of ACA were controlled by the intensity of Asian monsoon versus the westerlies under the governance of solar insolation. Generally increased moisture since the late Holocene indicated by the ARM/SIRM ratio favored cultural exchange and integration between the western and the eastern Eurasia, which paved the way for the formation of ASR. Coincidence between significant increase in moisture at ~200 BC suggested by the ARM/SIRM ratio and the formation of ASR indicates moisture as an important factor that facilitated the formation of ASR. The onsets of three prosperity periods of ASR in the history generally correspond to periods when moisture was relatively high, nevertheless, stagnant periods of ASR do not coincide with periods when moisture was relatively low in the core area of ACA. Disorganized correlations between stagnant periods of ASR and moisture changes in the core area of ACA suggest that moisture is not the decisive factor influencing the evolution of ASR.
Lay Summary: Being part of a social network means that responses to social confrontations

11 12 Territorial contests often occur in the presence of conspecifics not directly involved in the 13 interaction. Actors may alter their behaviour in the presence of this audience, an ‘audience 14 effect’, and audiences themselves may alter their behaviour as a result of observing an 15 interaction, a ‘bystander effect’. Previous work has documented these effects by looking at 16 each in isolation, but to our knowledge, none has investigated their interaction; something 17 that is more likely to represent a realistic scenario for species where individuals aggregate 18 spatially. We therefore have a somewhat limited understanding of the extent and direction of 19 these potentially complex indirect social effects on behaviour. Here we examined how 20 audience and bystander effects work in tandem to modify resident male aggressive behaviour 21 towards intruders in European fiddler crabs, Afruca tangeri. We found that male crabs with 22 an audience showed greater aggressive behaviour towards an intruder compared to males 23 without an audience, but only if they had acted as a bystander to an aggressive signalling 24 interaction prior to the intrusion. Indeed, bystanding during aggressive interactions elevated 25
Europese ervaringen met integrale planning van infrastructuur en ruimtelijke ordening voor goederenvervoer en logistiek

Samenvatting De verwachte groei van het vrachtverkeer in Europa vraagt om een optimalisatie van multimodale transport ketens. Nationale infrastructuurbeheerders moeten van instrumenten worden voorzien om de keuzes op het vlak van multimodaliteit door de transporten logistieksector te kunnen beïnvloeden. Dit kan eraan bijdragen dat nationale infrastructuurbeheerders de optimale werking van hun netwerken kunnen garanderen en zij toekomstige investeringen efficiënt kunnen inzetten. De traditionele focus van deze beheerders op infrastructuurplanning leidt meer en meer tot problemen bij het inspelen op maatschappelijke veranderingen en houdt bovendien geen rekening met de drijvende krachten in de transporten logistieksector.
Chapter 6: Optimizing continuous cover forest management

The practice of silviculture involves the art and science of controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society on a sustainable basis (Helms 1998). Silvicultural practices are often divided into two broadly defined management systems, which in North America are usually referred to as “evenaged” and “uneven-aged” management. In the context of this book, “uneven-aged” management is synonymous with continuous cover forestry (CCF). The choice of appropriate management system is guided by case-specific considerations, including ecological requirements of tree species currently present and desired; effects of timber harvest on forest flora and fauna; risk of damage from wildfire, insects, or pathogens; and financial and other landowner objectives for the managed forest. Skillful use of silvicultural practices can achieve the landowner’s objectives with greater assurance of success than will reliance on natural processes alone. Financial objectives are important for both public and private forest land managers. The goal of this chapter is to lay out the theoretical foundations for evaluating the relative economic efficiency of alternative forest management systems and to present an overview of approaches and applications used for studying the economic questions of uneven-aged management. Our review focuses on stand-level economic studies. A forest stand serves as the smallest operational unit of forestry, and is thus the appropriate level for investigating the efficiency of alternative chains of stand management. Like the majority of studies in this field, we consider and formulate
Targeted Pharmacological Heme-Oxygenase-1 Induction as a Therapy for Diabetes

Diabetes is a chronic disease characterized by elevated blood sugar levels resulting from either a lack of insulin production or resistance to insulin. About 230 million people worldwide had diabetes in 2010. The global figure of people with diabetes is projected to increase to 333 million in 2025, and 430 million in 2030 [1]. The majority of diabetes patients are not insulindependent and able, at least initially, to produce the hormone. This type of diabetes mellitus (DM) is termed type 2 diabetes. Insulin resistance is a fundamental aspect of the etiology of type 2 diabetes. Subjects with diabetes have an increased risk of ischemic heart disease, atherosclerosis and nephropathy [2,3]. Obesity, which is a major public health concern worldwide, increases the risk of type-2 diabetes [3]. Type 2 diabetes is caused by a combination of insulin resistance coupled with insufficient production of insulin to overcome the insulin resistance [4]. Oxidative stress plays a key role in the pathogenesis of micro-and macrovascular diabetic complications. There is now convincing evidence that redox reactions associated with CO metabolism play key roles in adaptive processes of tissues towards oxidative stress. Cells and tissues produce significant amounts of CO from heme degradation catalyzed by microsomal heme oxygenases (HO).

Human Body Dimensions for Biomechanical Modelling: A Review

The knowledge of human body proportion and segmental properties of limbs, head and trunk are of fundamental importance in biomechanical research. As many methods are employed, it is important to know which they are currently available, which data on human body masses, lengths, center of mass (COM) location, weights and moment of inertia are available and which methods are most suitable for a specific research purposes. The present review examines the literature concerning human body segments properties for biomechanical purposes. It emerges that data obtained in studies on cadaveric specimens are still the most accurate, whilst technological tools currently available are manifolds, each one with proper advantages and disadvantages. Classical studies were focused mainly on white men, while in recent year the available data of body segments has been extended to children, woman, and other races. Also, data on special population (obese, pregnant women) are starting to appear in the scientific literature.
An Adaptive Quality Switch-aware Framework for Optimal Bitrate Video Streaming Delivery

Given a large number of online video viewers, video streaming, over various networks, is important communication technology. The multitude of viewers makes it challenging for service providers to provide a good viewing experience for subscribers. Video streaming capabilities are designed based on concepts including quality, viewing flexibility, changing network conditions, and specifications for different customer devices. Adjusting the quality levels, and controlling various relevant parameters to stream the video content with good quality and without interruption is vital. This paper proposes an adaptive framework to balance the average video bitrates with respect to appropriate quality switches, making the transition to higher switches more seamless. The quality adaptation scheme increases the bitrates to the maximum value at their current quality switch before shifting to a higher level. This reduced switching times between levels and guarantees the stability of viewing and avoids interruptions. The use of a dynamic system ensures optimal performance, by controlling system parameters and making the algorithm more tunable. We built the system using an open-source DASH library (Libdash) with QuickTime player, studied the video load changes on two performance parameters, Central Processing Unit and Memory usages that have a high impact on multimedia quality. Consequently, the values of parameters that affected the performance of video streaming could be decreased, permitting users to regulate the parameters according to their preferences. Further, reducing the switching levels will reduce the overloads that occur while transferring from one level to another.
Humpback Whales in the Western Indian Ocean

Whales are difficult to study. These large marine mammals cannot be maintained in captivity so they have to be studied in nature, and observing their underwater behavior becomes a challenge. The extensive distribution, large size, and aquatic life style of these leviathans constrain efforts to observe and understand the scale of what is being studied. Researchers have dealt with this challenge with wit, determination and creativity. Large whales are known for using long distance acoustic communication to coordinate social interactions such as mate attraction and group feeding, as well as a means for orientation and navigation. Therefore, sound is relied on to help “see” beyond the surface. Marine mammalogists were the first to modify existing technology from ocean bottom sensors to develop novel ways to listen underwater, taking advantage of the fact that these animals rely mostly on sound to survive and reproduce. In effect, biologists eavesdrop on the underwater lives of marine mammals by listening. Researchers listen to humpback whales using different passive acoustic technologies that span a variety of spatial and temporal scales. In this paper, studies conducted in Brazilian waters are reviewed, primarily in the Abrolhos Bank region, where basic and advanced technologies have been used to understand the acoustic ecology of this large marine mammal species. Male humpback whale culture, their social dynamics revealed by spatial and temporal vocal activity patterns, and their interaction with the encroaching noise generated by humans, are reviewed.
21st International Research/Expert Conference

Over the past few decades, transports have undergone a profound transformation that has recently rapidly accelerated. The renovation regards more the management and electronic revolution than mechanical innovation. Because of these changes in the industry, numerous traditional companies have suffered from dramatic crises, which led to the closure of certain iconic airlines and numerous fusions and acquisitions, substantially modifying the structure of the industry and the networks development. Over the years, the complexity of the networks grew as airlines responded to the forces of economic and social changes. LCAs have also induced inter-modal competition with high speedy trains and international buses. Intra-modal competition is emerging following the EU liberalization of international passenger services since January 1, 2010. Depending on negotiations between member States, the next steps could affect domestic regulations, with options ranging from competition for the market, to full liberalization. 1. TRANSPORT AND TOURSIM Innovation in tourism proceeds along two kinds of directions: One is going by adopting on line full services, the other one is looking for all the ways for reducing costs 1. The most appealing and innovative technological tools in considering tourism, continue to be, like always, the transport means, especially since they are managed and booked through the web, so the last innovation in travels have been realized in air transport. The reciprocity between tourism and passenger transport companies is well emphasized 2. Airlines are especially close to tourism, providing vital links particularly for long-haul travel. Tourism, in return, is a significant driving factor that enables many developments in air transport 3. Over the past few decades, the airline industry has undergone a profound transformation that has recently rapidly accelerated 4. The origin of this process of change lies in the deregulation of this industry, which began in the late 1970s in the United States and led to the entry of new actors and a subsequent increase in competition. Born as the most expensive means, air travels are now less exclusive than train travels. Low cost companies are born on the basis of charter style and serving short haul distances. They are now so established that future will let us to see the low cost short haul companies expanding into low cost -long haul – companies 5. The interplay of aircraft technology and network development continues to the present days, but along the way, some of small cities have become important gateways, providing access to national and regional markets. Their airports became hubs connected to dominant cities on the transcontinental routes and the regional emerging airlines began to serve nearby centers with feeder services. Over the years the complexity of the networks grew as airlines responded to the forces of economic and social development and technological improvement of aircrafts, affecting centrality, intermediacy and

Imaging characteristics of H3 K27M histone-mutant diffuse midline glioma in teenagers and adults.

Background To assess anatomical and quantitative diffusion-weighted MR imaging features in a recently classified lethal neoplasm, H3 K27M histone-mutant diffuse midline glioma [World Health Organization (WHO) IV]. Methods Fifteen untreated gliomas in teenagers and adults (median age 19, range, 14-64) with confirmed H3 K27M histone-mutant genotype were analysed at a national referral centre. Morphological characteristics including tumour epicentre(s), T2/FLAIR and Gadolinium enhancement patterns, calcification, haemorrhage and cyst formation were recorded. Multiple apparent diffusion coefficient (ADCmin, ADCmean) regions of interest were sited in solid tumour and normal appearing white matter (ADCNAWM) using post-processing software (Olea Sphere v2.3, Olea Medical). ADC histogram data (2nd, 5th, 10th percentile, median, mean, kurtosis, skewness) were calculated from volumetric tumour segmentations and tested against the regions of interest (ROI) data (Wilcoxon signed rank test). Results The median interval from imaging to tissue diagnosis was 9 (range, 0-74) days. The structural MR imaging findings varied between individuals and within tumours, often featuring signal heterogeneity on all MR sequences. All gliomas demonstrated contact with the brain midline, and 67% exhibited rim-enhancing necrosis. The mean ROI ADCmin value was 0.84 (±0.15 standard deviation, SD) ×10-3 mm2/s. In the largest tumour cross-section (excluding necrosis), an average ADCmean value of 1.12 (±0.25)×10-3 mm2/s was observed. The mean ADCmin/NAWM ratio was 1.097 (±0.149), and the mean ADCmean/NAWM ratio measured 1.466 (±0.299). With the exception of the 2nd centile, no statistical difference was observed between the regional and histogram derived ADC results. Conclusions H3 K27M-mutant gliomas demonstrate variable morphology and diffusivity, commonly featuring moderately low ADC values in solid tumour. Regional ADC measurements appeared representative of volumetric histogram data in this study.
