Economic Science by Pawan Upadhyay — The Best Economy Model :-
This repository presents “Economic Science by Pawan Upadhyay,” a comprehensive and balanced economic framework built on the combined strength of Domestic Consumption and Export-Driven Growth. This model defines the foundation of a stable, resilient, and growth-oriented national economy capable of withstanding both internal and external shocks.
At the core of this framework is the principle that a nation must cultivate a solid domestic economy while simultaneously boosting exports. When domestic demand weakens, export demand fills the gap; when global markets slow down, strong internal consumption sustains growth. This dual-engine approach ensures long-term economic stability.
The model emphasizes that economic strength is not dependent on a single variable, but on the coordinated functioning of multiple factors:
Key Components of the Model :-
Domestic Consumption + Export: The two main drivers of national growth.
Deficit Management: Strong savings, efficient taxation, investment inflows, and tourism revenue help reduce both fiscal and current account deficits.
Demand, Supply & Production: Stable demand, timely supply, and expansion of production capacity drive continuous growth.
Consumer Purchasing Power: Strong income, job creation, and affordable pricing strengthen domestic demand.
Strong but Comfortable Currency: A balanced strong currency reduces import costs without harming export competitiveness.
Cash Inflow vs. Outflow: Increasing foreign exchange inflow and reducing unnecessary outflow fortify national reserves.
Savings & Reserves: National savings act as a shield during inflation spikes, droughts, or global recessions.
Insights on Export Dynamics :-
The model explains how companies profit even with a strong currency by increasing export quantity or reducing production costs through cheaper imports. Profit = Earning − Expenditure A strong currency lowers import costs, increasing profit margins and making the economy more efficient.
Purpose of This Repository :-
This repository documents the complete economic model, provides theoretical foundations, and offers policymakers, students, and researchers a structured approach to understanding sustainable economic development.

Economic Science by Pawan Upadhyay
A Balanced and Resilient Economic Growth Model :-
This repository presents “Economic Science by Pawan Upadhyay,” a comprehensive economic framework built on the dual strength of Domestic Consumption and Export-Driven Growth. The model outlines how nations can achieve long-term stability, strong financial health, and sustainable growth by balancing internal demand with external trade performance.
Key Principles of the Model :-
Domestic Consumption + Export = Best Economy
A nation becomes resilient when it has:
Strong domestic demand
Strong export performance
If one weakens, the other fills the gap — stabilizing the economy.
Managing Fiscal & Current Account Deficits
The model highlights four essential strategies:
Strong national saving
Efficient tax revenue collection
Increased domestic + foreign investment
Growth in tourism and foreign currency inflow
These pillars help control deficits and strengthen national finances.
Inflation, Income & Demand
Stable growth requires:
Low to moderate inflation
Rising income levels
Affordable product pricing
Strong consumer purchasing power
Demand and supply must remain balanced to avoid shocks.
Production Capacity & Supply Chain
Timely production and efficient supply chains meet both:
Domestic demand
Export demand
Higher production capacity drives economic expansion.
Strong but Comfortable Currency
A strong currency:
Makes imports cheaper
Reduces production cost
Increases profitability
A “comfortable level” of strength ensures exports remain competitive.
Cash Inflow vs Cash Outflow
A strong economy ensures:
More money flows into the country
Less money flows out unnecessarily
This boosts foreign reserves and economic security.
Savings & Economic Stability
National savings and reserves help during:
Drought
Inflation spikes
Global recessions
Domestic economic shocks
Export Profitability Formula
Profit = Earning − Expenditure
A strong currency lowers import-related expenditure, increasing profits even if export prices remain competitive.
Purpose of This Repository
This repository documents the complete economic model, offering:
Theoretical insights
Policy frameworks
Practical explanations
Real-world economic logic
It is suitable for students, researchers, economists, and policymakers.

Chalcogenide Sensitized Carbon Based TiO2 Nanomaterial For Solar Driven Applications
No full textThe demand for renewable energy is growing because fossils fuels are depleting at a rapid pace. Solar energy an abundant green energy resource. Utilizing this resource in a smart manner can resolve energy-crisis related issues. Sun light can be efficiently harvested using semiconductor based materials by utilizing photo-generated charges for numerous beneficial applications. The main goal of this thesis is to synthesize different nanostructures of TiO2, develop a novel method of coupling and synthesizing chalcogenide nanocrystals with TiO2 and to study the charge transportation effects of the various carbon allotropes in the chalcogenide nanocrystal sensitized TiO2 nanostructure.We have fabricated different nanostructures of TiO2 as solar energy harvesting materials. Effects of the different phases of TiO2 have also been studied. The anatase phase of TiO2 is more photoactive than the rutile phase of TiO2, and the higher dimension of the TiO2 can increase the surface area of the material which can produce higher photocurrent.Since TiO2 only absorbs in the UV range; to increase the absorbance TiO2 should be coupled to visible light absorbing materials. This dissertation presents a simple approach to synthesize and couple chalcogenide nanocrystals with TiO2 nanostructure to form a heterostructured composite. An atmospheric pressure based, single precursor, one-pot approach has been developed and tested to assemble chalcogenide nanocrystal on the TiO2 surface. Surface characterization using microscopy, X-ray diffraction, and elemental analysis indicates the formation of nanocrystals along the nanotube walls and inter-tubular spacing. Optical measurements indicate that the chalcogenide nanocrystals absorb in the visible region and demonstrate an increase in photocurrent in comparison to bare TiO2 nanostructure. The CdS synthesized TiO2 nanostructure produced the highest photocurrent as measured in the three electrodesystem. We have also assembled the PbS nanocrystal sensitized photoanode using the one pot method.Finally, the charge transportation effect of carbon allotropes has been studied. For this we assembled TiO2 conductive carbon chalcogenide nanocomposite system. Surface and elemental characterization using electron microscopy, EDX (energy dispersive x-ray) and x-ray diffraction pattern, provide the insights into the assembly of the nanostructure. Optical absorbance, Photo chronometry, Linear sweep voltammetry, and electrochemical impedance analysis have been used to provide opto-electronic performance of the material. We have studied the loading effect of various carbon allotropes, [fullerene (C60), reduced graphene oxide (RGO), carbon nanotubes (CNTs), and graphene quantum dots (GQDs)], loading effect of chalcogenide, and effect of nitrogen doping on the carbon allotropes to optimize the performance of the heterostructure.This dissertation is expected to impact the materials synthesis strategies and assemble the nanostructures used in composite electrode driven applications in the area of photo electrochemistry, PV, solar-fuels, and other associated topics of energy storage and sensing

Cyber-Physical Co-Simulation Testbed for Real-Time Reactive Power Control in Smart Distribution Network
No full textExisting electric power distribution systems are evolving and changing as a result of the high renewable energy sources integration. Hence, future smart distribution networks will involve various technical challenges; one of them is real-time monitoring and controlling the network to operate it effectively and efficiently. This paper develops and analyzes a cyber-physical co-simulation testbed for real-time reactive power control in the smart distribution network. The testbed is a two-layer system, with Typhoon HIL 604 representing the physical layer and the other layer as a cybernetic layer. The cybernetic layer is used to model a test system and control reactive power from smart inverters in real-time. The implementation of real-time reactive power control of smart inverters on a CIGRE MV distribution network is shown in this study. The proposed testbed's usefulness in real-time reactive power control is demonstrated through simulation results.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Intelligent Electrical Power Grid
Analysis of EMG Signal for Prosthetic hand based on Fuzzy Logic Technique
No full textLidská ruka je koncový orgán horní končetiny, který slouží k důležité funkci uchopení, stejně jako důležitý orgán pro vnímání a komunikaci. Je to úžasný příklad o tom, jak komplexní mechanismus může být implementovaný, schopný chápat velice komplexní a užitečné úkoly používáním velmi efektivní kombinace mechanismů, snímání a řídicích funkcí. Elektromyogram (EMG) byl původně vyvinutý pro vyšetrování svalnatého nepořádku. Klinické aplikace se brzo rozšířila, nejpozoruhodněji ve výzkumu epilepsii a nakonec se stal populární po zavedení protéz, specificky tělem poháněných protéz. EMG nahrávání je použito pro studování funkčního stavu svalu během různých pohybů. Cílem tohoto projektu je vyvinutí elektromyogramové (EMG) metody třídění, která bude pomáhat v aplikacích jako systém pracující v reálném čase. První část tohoto projektu bylo získávání informací. Údaje reálného času byly zaznamenaný pomocí EMG monitorovacího systému (BIOPAC) a kompletní datová sada různých osob byl zaznamena. Tyto EMG data byly konvertované ze souboru ASCII do čitelné formy pro MATLAB. Druhou částí projektu byla extrakce vlastností. Pět tradičních parametrických rysů bylo vypočítáno, jmenovitě Integrovaný EMG (IEMG), variance (VAR), Zero Crossing (ZC), Slope Sign Changes (SSC) a Vlnová délka (WL). Třetí část projektu byla klasifikace EMG vzorů s použitím fuzzy logiky. Výsledky jsou docela slibné
