Noise pollution is caused by various sources like industries, transportation, social events, and construction activities. It can negatively impact human health by causing hearing loss, cardiovascular issues, and sleep disorders. It also disturbs wildlife. The Indian constitution obligates the government to protect the environment. Laws like the Air and Environment Protection Acts define noise as a type of air pollution. The Supreme Court has upheld reasonable restrictions on noise to prevent nuisance. Controlling noise pollution requires enforcement of strict regulations as well as public awareness campaigns about its health impacts.
Noise Mapping and Sound modelling
hat is Noise Mapping ?
A Noise Map is a map of an area which is coloured according to the noise levels in the area. Sometimes, the noise levels may be shown by contour lines which show the boundaries between different noise levels in an area.
The noise levels over an area will be varying all the time. For example, noise levels may rise as a vehicle approaches, and reduce again after it has passed. This would cause a short-term variations in noise level. In the slightly longer term, noise levels may be higher in peak periods when the roads are busy, and lower in off-peak periods. Then again, there is a greater volume of activity from more people and traffic in the day-time than in the evening or at night. In the longer term, wind, weather and season all affect noise levels.
This means that it is not possible to say with confidence what the noise level will be at any particular point at any instant in time, but where the noise sources are well-defined, such as road or rail traffic, or aircraft, then it is possible to say with some confidence what the long-term average noise level will be.
It may be thought that the best way of doing this is by measurement, but experience shows that this is not the case. For a start, a long-term average must be measured over a long period of time. Secondly, to obtain complete coverage of an area, measurements would have to be made on private property, where access might be difficult, and thirdly, measurements cannot distinguish the different sources of noise, so they would not be able to give information on how much noise was being made by each of the sources in an area.
For these and other reasons, noise mapping is usually done by calculation based on a computerised noise model of an area, although measurements may be appropriate in some cases.
A further benefit of having a noise model is that it can be used to assess the effects of transportation and other plans. Thus the effect of a proposed new road can be assessed and suitable noise mitigation can be designed to minimise its impact. This is particularly important in noise action planning, where a cost-benefit analysis of various options can be tested before a decision is made.

Noise Pollution
Noise pollution arises from various sources like vehicles, construction machinery, and household appliances. It is defined as unwanted sound that disrupts human or animal activity. Sound is measured in frequency (cycles/second), intensity (sound energy/second), and decibel level which is a logarithmic ratio of measured to reference intensity. The human ear can detect sounds from 20-20,000 Hz. Noise pollution has physiological effects like hearing loss, and psychological effects like sleep disturbances and annoyance. Control methods include using mufflers and insulation to reduce sound transmission, and ear protection for those working in noisy environments.

Noise pollution can be caused by both industrial and non-industrial sources. It can negatively impact human health through auditory effects like hearing loss and non-auditory effects such as sleep disturbance, cardiovascular problems, and annoyance. Noise pollution can be controlled through reducing noise at the source, preventing transmission, and protecting receivers. Some techniques to reduce noise include installing barriers, maintaining equipment, limiting loud speakers, and developing green spaces. Regulations define acceptable noise limits to protect human health and welfare.
Pollution
Pollution harms human health in several ways. Air pollution causes respiratory and cardiovascular diseases and can kill millions per year. Water pollution from sewage and industrial waste contaminates drinking water and causes thousands of deaths daily from diseases. Soil pollution from heavy metals and other pollutants undermines soil quality and fertility. Various types of pollution like noise, thermal, and radiation pollution also negatively impact human health. Collective global action is needed to treat wastes, use renewable resources, and implement standards to reduce pollution and protect human well-being.

The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.

Deep Software Variability and Frictionless Reproducibility
Deep Software Variability and Frictionless ReproducibilityUniversity of Rennes, INSA Rennes, Inria/IRISA, CNRS
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.
