MFC Cosinus
The document defines a CPropertiesDlg class that inherits from CDialog and contains an integer member variable m_edit1. It also defines a CCosinusView class that contains an integer member m_pasi. The CCosinusView class opens an instance of the CPropertiesDlg as a modal dialog when the OnFunctionsCosinus method is called, and assigns the m_edit1 value from the dialog to its own m_pasi member variable.

Electron transport in one dimensional nanosystems
This document provides an overview of electron transport theory in one-dimensional nanoscale systems. It begins with an introduction to Landauer theory and asymmetric potential barriers. It then examines tight binding models of perfect and defective wires to understand electron transmission. Applications to scanning tunneling microscopes are discussed, modeling the tip-surface junction as a tight binding wire. Vibrational effects on conduction are also considered.
Tools.cpp
This C++ code defines several functions used as tools: ProgressBar prints a progress bar to the console, IntToString converts an integer to a string, BernoulliDistr returns a random boolean value based on a probability, Distance calculates the distance between two points on a grid, NormalDistr generates a random number from a normal distribution, and LogNormal generates a random number from a log-normal distribution.
Smell in real noses: how the environment changes vibrations
This document discusses Benjamin Yiwen Färber's research into how the vibrational frequency of odor molecules is affected by the environment inside the nose. It begins by summarizing the biological process of smell and Turin's theory that odor discrimination is based on the vibrational frequencies of molecules. It then models odor molecules as diatomic harmonic oscillators and examines how the oscillator's frequency is altered by environmental factors like external charges and binding to olfactory receptors. The document relates the harmonic oscillator model to the quantum mechanical Morse potential model and tight binding model of diatomic molecules.
Dynamical symmetry breaking in vibration-assisted transport through nanostruc...
This document summarizes a theoretical model of electron transport through a nanostructure with strong electron-vibron coupling. A single molecule is coupled to many vibronic modes, and at low energies transport is dominated by electron-vibron processes where an electron transfers through the molecule accompanied by the excitation or emission of vibrons. When the vibron frequencies form a harmonic series, energetically degenerate vibronic configurations can contribute to transport. Both negative differential conductance features and gate asymmetry are predicted due to interplay between Franck-Condon suppression and spin/orbital degeneracies, which give rise to slow transport channels.

Statistics.cpp
This C++ code defines functions for statistical analysis and logging of simulation data. It includes functions to initialize log vectors for salesmen data, log field visits to a grid, and write output log files. Functions are also defined for histogramming data, smoothing and averaging vectors, and calculating statistics like the midpoint and variance of a data set.
Could humans recognize odor by phonon assisted tunneling
This document discusses a proposed physical mechanism for how humans could recognize odors through phonon-assisted tunneling. The mechanism involves inelastic electron tunneling between donor and acceptor sites in olfactory receptors that is mediated by the absorption or emission of odorant molecule phonons. The document evaluates the viability of this proposed mechanism using theoretical models and estimates of parameter values. It finds that the mechanism is physically plausible and consistent with observed features of the sense of smell, provided olfactory receptors have certain general properties that allow electron transfer on appropriate timescales.
Statistics.hpp
This document contains C++ code that defines two classes: Histogram and Statistics. The Histogram class is used to store and represent histogram data, including a vector of doubles for the data, minimum value, and bin size. The Statistics class contains various public methods for initializing simulation parameters, logging field visits and salesman data, writing data to files, processing the data by dividing, smoothing, and calculating statistics like midpoint and variance. It stores the logged data and simulation parameters as private member variables.
Structure-odor relations: a modern perspective
1) This document provides an overview of structure-odor relations (SORs), discussing the challenges in relating molecular structure to odor perception and reviewing some prominent odor categories.
2) A key difficulty is that no two odorants have been found to have exactly the same odor, despite similarities in structure, and the human olfactory system appears to have infinite resolution.
3) Theories of SORs have generally been unsuccessful at predicting odor based on structure alone. Conformational analysis and quantitative structure-activity relationships have had limited predictive power due to unknown receptor structures.
Dpsm simu.cpp
This document contains C++ code for simulating a dynamic pricing model. It defines classes for customers and salespeople, and includes methods for initializing the simulation, having customers and salespeople interact on a grid, and adjusting salesperson prices over time using different strategies. The simulation runs for a set number of iterations, logging data at intervals to output files.
Econophysics
This document summarizes a statistical model of a stock market consisting of buyers and sellers interacting on a lattice. Sellers are fixed in position with set prices, while buyers diffuse randomly and may purchase from sellers based on the difference between the seller's price and the buyer's valuation. The model could later be expanded to have sellers dynamically adjust prices based on aggregate demand, similarly to models of Brownian motion in financial markets. Statistical physics approaches are applied to understand this complex system of many interacting agents as an equilibrium process.
Gps c
This sample program demonstrates how to access Meinberg GPS receivers via the binary data protocol. It can work via a serial port or network socket connection depending on the target operating system. It requires several other modules and supports Windows, Linux, QNX, and DOS targets. The program checks return codes from API functions, gets receiver information, status information, position, time zone, and synthesizer settings. It also has the ability to set the synthesizer frequency and phase.

Having issues with passing my values through different functions aft.pdf
The document describes creating an EmployeeRecord class to store employee data including ID, name, department, and salary. It includes the class definition with private member variables and public getter/setter functions. The main() function demonstrates creating an EmployeeRecord object, passing values to the constructor, and calling printRecord() to output the data. Issues were encountered passing values through functions after construction. The solution comments out incorrect nulling of string pointers in the constructor, fixes the getter/setter functions to properly copy between members and parameters, and changes the salary input in main to not use a pointer.

Discussion Questions
(Two questions from Chapter 6)
1. What industry forces might cause a propitious niche to appear or disappear?
The environment or industry changes. The company or SBU continues to make its products or services but the size of the market changes. The company or SBU changes. The same market demand continues for some specific products or services but the company or SBU itself changes so that there is no longer asynchronization between itself and the market. If a company or SBU loses its niche, it is likely to get much less profitable unless it gets a new niche. The specifics of what might happen depends upon how the company had lost its niche. The possibilities of class discussion can be almost endless.
2. What does a business have to consider when trying to follow a cost leadership strategy and a differentiation strategy simultaneously? Can you name a company doing this?
A cost leadership strategy is a “company’s ability to design, produce, and market a comparable product more efficiently than t ...

If a company or SBU loses its niche, it is likely to get much less profitable unless it gets a new niche. The specifics of what might happen depends upon how the company had lost its niche. The possibilities of class discussion can be almost endless.

Ass 1
The document contains a C++ program to print employee information including their employee number, name, gross salary, and net salary. It defines an Employee class with private data members for this information and public member functions to read, calculate net salary, and print the employee details. The main function allows the user to enter the number of employees, reads their details into an array of Employee objects, calculates the net salary for each, and prints a report of the employee information. It provides sample output for one employee with a basic salary of Rs. 10,000.

Introduction to MPI
This document provides an introduction and overview of MPI (Message Passing Interface). It discusses:
- MPI is a standard for message passing parallel programming that allows processes to communicate in distributed memory systems.
- MPI programs use function calls to perform all operations. Basic definitions are included in mpi.h header file.
- The basic model in MPI includes communicators, groups, and ranks to identify processes. MPI_COMM_WORLD identifies all processes.
- Sample MPI programs are provided to demonstrate point-to-point communication, collective communication, and matrix multiplication using multiple processes.
- Classification of common MPI functions like initialization, communication, and information queries are discussed.

Statistics.cpp
This C++ code defines functions for statistical analysis and logging of simulation data. It includes functions to initialize log vectors for salesmen data, log field visits to a grid, and write output log files. Functions are also defined for histogramming data, smoothing and averaging vectors, and calculating statistics like the midpoint and variance of a data set.
Could humans recognize odor by phonon assisted tunneling
This document discusses a proposed physical mechanism for how humans could recognize odors through phonon-assisted tunneling. The mechanism involves inelastic electron tunneling between donor and acceptor sites in olfactory receptors that is mediated by the absorption or emission of odorant molecule phonons. The document evaluates the viability of this proposed mechanism using theoretical models and estimates of parameter values. It finds that the mechanism is physically plausible and consistent with observed features of the sense of smell, provided olfactory receptors have certain general properties that allow electron transfer on appropriate timescales.
Statistics.hpp
This document contains C++ code that defines two classes: Histogram and Statistics. The Histogram class is used to store and represent histogram data, including a vector of doubles for the data, minimum value, and bin size. The Statistics class contains various public methods for initializing simulation parameters, logging field visits and salesman data, writing data to files, processing the data by dividing, smoothing, and calculating statistics like midpoint and variance. It stores the logged data and simulation parameters as private member variables.
Structure-odor relations: a modern perspective
1) This document provides an overview of structure-odor relations (SORs), discussing the challenges in relating molecular structure to odor perception and reviewing some prominent odor categories.
2) A key difficulty is that no two odorants have been found to have exactly the same odor, despite similarities in structure, and the human olfactory system appears to have infinite resolution.
3) Theories of SORs have generally been unsuccessful at predicting odor based on structure alone. Conformational analysis and quantitative structure-activity relationships have had limited predictive power due to unknown receptor structures.
Dpsm simu.cpp
This document contains C++ code for simulating a dynamic pricing model. It defines classes for customers and salespeople, and includes methods for initializing the simulation, having customers and salespeople interact on a grid, and adjusting salesperson prices over time using different strategies. The simulation runs for a set number of iterations, logging data at intervals to output files.
Econophysics
This document summarizes a statistical model of a stock market consisting of buyers and sellers interacting on a lattice. Sellers are fixed in position with set prices, while buyers diffuse randomly and may purchase from sellers based on the difference between the seller's price and the buyer's valuation. The model could later be expanded to have sellers dynamically adjust prices based on aggregate demand, similarly to models of Brownian motion in financial markets. Statistical physics approaches are applied to understand this complex system of many interacting agents as an equilibrium process.

Having issues with passing my values through different functions aft.pdf
The document describes creating an EmployeeRecord class to store employee data including ID, name, department, and salary. It includes the class definition with private member variables and public getter/setter functions. The main() function demonstrates creating an EmployeeRecord object, passing values to the constructor, and calling printRecord() to output the data. Issues were encountered passing values through functions after construction. The solution comments out incorrect nulling of string pointers in the constructor, fixes the getter/setter functions to properly copy between members and parameters, and changes the salary input in main to not use a pointer.

The document contains a C++ program to print employee information including their employee number, name, gross salary, and net salary. It defines an Employee class with private data members for this information and public member functions to read, calculate net salary, and print the employee details. The main function allows the user to enter the number of employees, reads their details into an array of Employee objects, calculates the net salary for each, and prints a report of the employee information. It provides sample output for one employee with a basic salary of Rs. 10,000.

Introduction to MPI
This document provides an introduction and overview of MPI (Message Passing Interface). It discusses:
- MPI is a standard for message passing parallel programming that allows processes to communicate in distributed memory systems.
- MPI programs use function calls to perform all operations. Basic definitions are included in mpi.h header file.
- The basic model in MPI includes communicators, groups, and ranks to identify processes. MPI_COMM_WORLD identifies all processes.
- Sample MPI programs are provided to demonstrate point-to-point communication, collective communication, and matrix multiplication using multiple processes.
- Classification of common MPI functions like initialization, communication, and information queries are discussed.

Alien life forms
The document discusses several possibilities for the existence of alien life forms:
1) There may be another human species in our galaxy or universe that evolved separately from apes, refuting evolution theory.
2) Advanced civilizations like those depicted in Star Wars could exist elsewhere in the galaxy.
3) Other dimensions may contain worlds like those in Harry Potter or Lord of the Rings with separate human species.
4) Greys or other aliens may have communicated telepathically or visited Earth. Their bodies and technology could differ greatly from humans.
Spaceengine2
This document discusses several physics concepts including:
1. The relationship between thermal conductivity, surface area, heat transfer rate, and temperature gradient in a pipe.
2. How Lorentz transformations relate velocity and acceleration in special relativity.
3. How the Faraday tensor relates electric and magnetic field components between inertial frames in motion relative to each other.
Structural Language
This document discusses structural language and how statistical analysis can be used to understand communication between agents through sequences of symbols or actions. It provides an example of two fighters in a computer game each with a repertoire of moves they use in a sequence to battle each other. The document argues that without understanding the meaning of individual symbols, one can still analyze repetitive structures and compare sequences to understand communication. It then discusses using statistical methods like Kendall's tau and Spearman's coefficient to analyze pairings between sequences and look for correlations. The document concludes by discussing how current computer games follow basic rules for situations but the next step is for computers to rely on sequences of their own decisions to become more autonomous agents.
Language
This document discusses structural language and statistical analysis of sequences of signs or data. It uses examples of fighters in a computer game applying sequences of moves and birds communicating with sequences of tones. It argues that statistical analysis of the structures and sequences can help understand languages without knowing the meaning of individual symbols. This includes finding repetitions in sequences and comparing structures using methods like the Kendall Tau and Spearman coefficient to analyze pairings in sequences and assess concordance and discordance. It also suggests computer games could incorporate more artificial intelligence by having computer players rely on sequences of decisions rather than situational rules to become more autonomous agents.
Spaceengine2
This document discusses equations related to heat transfer through pipes and the temperature gradient that results from fluid flow. It then speculates that quantum mechanical equations like the Fermi-Dirac distribution and theories of relativity may help explain the relationship between temperature and the movement of water particles through pipes. The document proposes that the velocity of water particles must be connected to temperature, that velocity is infinite, and that the movement of an inertial system through a vacuum must be related to the movement of the system.
Spaceengine
1. The document discusses equations relating thermal conductivity, surface area, temperature gradient, and heat transfer rate for water flowing through a pipe.
2. It then discusses how the movement of water particles through a tube is analogous to the movement of a train on rails, and how the laws of special relativity may need to be combined with temperature and quantum mechanics.
3. Finally, it presents equations for a von-Neumann type interaction describing an open boundary quantum system, where the wave function of a pointer after time t depends on the initial wave function and a parameter relating position and time.
Topology and Electrostatics
1. The document defines topological spaces and metric spaces. A topological space is a set endowed with a collection of open sets satisfying certain properties. A metric space is a topological space where the open sets are defined by a metric.
2. It then introduces Gauss's law, which states that the electric flux through a closed surface is proportional to the total charge enclosed by the surface.
3. Gauss's law can be applied to both discrete point charges and continuous charge distributions described by a charge density function.

The document discusses the results of a study on the impact of COVID-19 lockdowns on air pollution. Researchers found that lockdowns led to significant short-term reductions in nitrogen dioxide and fine particulate matter pollution globally as economic activities slowed. However, the impacts on greenhouse gases and long-term air quality improvements remain uncertain without permanent behavior and economic changes.
Aspelmeyer
This document discusses optomechanics and the use of quantum optics techniques to control mechanical systems. It provides a brief history of mechanical effects of light, including early predictions of radiation pressure and recent experiments cooling mechanical modes into the quantum ground state using laser radiation pressure. Current optomechanical systems are described, along with proposals to generate optomechanical entanglement and use optomechanics to teleport quantum states. Requirements for achieving quantum optomechanics experiments are discussed, and progress on developing systems meeting these requirements is summarized.
Arndt matter wave interferometry
The slide is about matter wave interferometry and discusses this subject first with regards to the following questions.
1. While quantum physics is a universally valid theory are there any mass, size or complexity limits ?
2. As quantum physics is a precise theory can we use quantum interferometry for particle metrology?
3. As there seems to be a limit of how far the quantum interferometry can be shown to exist how far can we extend the double slit interferometry to larger things ?
The author's perspective is therefore to show that he can do double slit wave interferometry with quite large molecules.
What is interesting to him is the velocity distribution or "velocity selection" as it is called in his poster.
Then the author continues to discuss different interferometry techniques such as the Talbot-Lau interferometre and its extension, the Kapitza-Dirac Talbot-Lau interferometre.
After this he starts mentioning quantum interferometry with "polyatomic strings" and continues to discuss a larger variety of techniques and molecules.

Applied Science: Thermodynamics, Laws & Methodology.pdf
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.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.

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.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

The cost of acquiring information by natural selection
This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
