Hans Deyssenroth studied Electrical Engineering at the TH Karlsruhe and Physics at the University of Basel. He worked as a Biometrician and led an IT department in the pharmaceutical industry. After retirement, he became actively engaged in challenging the validity of the Theories of Relativity. 

Abstract:

The Special Theory of Relativity is indirectly based on the null result of the MME. The skewed light path in the y-arm provides the time dilation, and in the x-arm there must be a length contraction to achieve the null result. This results in the Lorentz transformation. But applying the Quantum Theory to the MME, the light path in the y-arm is not tilted but perpendicular to the direction of movement. However, in this case the calculation of the length of the light path in the x-arm must be wrong, because this length must be the same as in the y-arm: s_x = s_y = 2L. In the text books this length is calculated via the time durations and has the result s_x = 2Lγ². But this contradicts the statement that the two-way lightspeed is isotropic and therefore independent of the movement velocity. The calculation of this length via the frequency or via the local lightspeeds (c-v) and (c+v) results as expected in s_x = 2L. There is an obvious conflict with the 120 years old interpretation of the MME.

Five experiments are presented that could reveal which interpretation is the correct one. Only now it is possible to perform these measurements with the newest technology. The results will reveal to us whether the mathematical basis of the Theories of Relativity is wrong or right. The experimental confirmations of these theories alone are not sufficient.

Abstract:

Several instances of use of biological warfare agents during World War I and World War II can be found in open literature. For the few decades after Biological and Toxin Weapon Convention in 1972, the use of these agents was not reported. But it again hogged the limelight after terrorists used the anthrax powder in United States in 2001 which claimed 22 casualties including five deaths. The use of biological, chemicals and explosive   warfare agents by terror groups is one of the biggest concerns in today’s scenario. The development of a technology for standoff detection of biological warfare agents to mitigate the threat. The technology utilizes UV Laser (266 nm) induced fluorescence (LIF) spectroscopy for the detection in bio-aerosol form. The technology has been demonstrated and the signals from bio-aerosols have been detected from distances of up to 1000 meter in both day and night conditions. The spectra are recorded of Bacillus Anthrax class stimulants/ bio-chemicals with the range and concentration.  The LIF results have recorded using the ICCD and MAPMT spectrometer detectors at day and night conditions. Absorption based ultrasonic laser Photoacoustic spectroscopic (LPAS) technique is developed based on Mid IR quantum cascade laser (7 to 9 micron), microphone and quartz enhance detectors. The Photoacoustic technique is made for without interference of audio sound and the presence Sunlight.  The  Standoff Photo acoustic technology have potential for the detection of hazardous molecules (like explosive, chemicals and drugs etc) in the form of solid, liquid  vapours, gases and aerosols. Photo acoustic  sensing technology have capabilities for the detection of traces, mixtures of molecules, post blast  materials,   these technologies in details will be discussed in my presentation.

Abstract:

We propose and theoretically explore reduced-symmetry (P- and T broken) states of graphene superlattices created by strong circularlypolarized ultrashort pulses. The conduction-band electron distribution in the reciprocal space forms an interferogram with discontinuities related to topological (Berry) fluxes at the Dirac points. Our findings hold promise for control and observation of ultrafast electron dynamics in topological solids and may be applied to petahertz-scale information processing.

One of the fundamental problems of topological physics of graphene is a direct observation of the Berry phase. This is related to the fact that the only realistic possibility of observing this phase is self-referenced interferometry of electronic waves in the reciprocal space. However, the Berry phase is ± π; the self-referenced interferometry doubles it to ±2π, which does not produce any discontinuities in the interference fringes. The Bragg scattering from the superlattices creates diffraction and “which way” interference in the reciprocal space reducing the Berry phase and making it directly observable in the electron interferograms, which can be read-out with time- and angle-resolved photoelectron emission spectroscopy (TR-ARPES). These interferograms give the most direct information about such fundamental topological field as Berry curvature of the reciprocal space. The femtosecond dynamics of such interferograms will provide direct information about electron momentum relaxation in graphene.

Abstract:

GOD created life in universe with sole purpose of Nirvana. The Einstein answered to the uncertainty principle as God doesn’t play dice was proven scientifically by Kumar and consequently proved by him that all forms of energy are manifestation of electrical energy with positive electrical energy being Shiv and negative electrical energy being Parvati (Shakti). The flow of energy from positive to negative is in the form of electromagnetic radiation hence blue shift (higher energy) to red shift (lower energy) leads to creation of life by conversion of energy into matter forming from sub-atomic particles to atomic particles leading to form the huge quantity of hydrogen gas. These hydrogen atoms are converted to stars, planets and satellites by the two fundamental principles or better can be said as the rules of GOD viz. Law of conservation of Energy and Law of conservation of Momentum to control the evolution of life in the Universe/Multiverse to lead it for Nirvana. Every life is having unique digital signature of GOD i.e. every male (positive energy) and female (negative energy) soul is uniquely coded to form the key and lock form of life thus giving the freedom for matter (body) and energy (soul) to interact (sex) for finding (Karma) the right code for Nirvana with a power for reproduction. Every Karma is converted to Bhagya (Destiny i.e. magnetic energy) in every birth and rebirth as the full previous karma information to the new life being reproduced during interaction (sexual intercourse) by themselves. This chakra (cycle) continues till nirvana. The right digital encoding can be done by diagnosing with mathematical tools the GOD’s image captured as shown in the image thus innovating, integrating and motivating with ideas of physics and its concepts.

Abstract:

The analysis of the Rainfall effects on the signal power attenuation is considered as a fundamental step in the satellite link adaptation and fade mitigation techniques due to the its major effect on the satellite communication services. This study presents an approach for analyzing the satellite link performance during rainfall in semi-tropical regions for frequencies above 10 GHz. The information from these analyses will be a good preliminary design benchmark for earth-sky microwave links in the subtropics and also provide a broad idea of rain attenuation and link performance for microwave engineers. Results show that a considerable change occurs in the performance of the wave propagated through the rain drops. The analyses are realistic approach for predicting the link characteristics based on actual measured rainfall rate.

Abstract:

Void fraction measurements are reviewed with emphasis on applications to multiphase flow. The presentation is divided into two main sections; intrusive where the probe penetrates into the flow field, and non-intrusive where the detection is done remotely. The latter is more preferrable than the former. We subdivided the non-intrusive techniques into into two main categories; nuclear and non-nuclear. In the nuclear section, we discussed the utilization of almost all types of radiations ,namely; beta, neutrons, gamma, X-ray, and near infrared. In the non-nuclear techniques, we presented the following methods; fluorescence, optical sensors, laser, autotransformer winding, ultrasonic, and photgraphy.

Abstract:

Significant progress on the device performance of organic solar cells (OSCs) with nearly 100% internal quantum efficiency has been made in recent years via the incorporation of new materials, morphology control, interface engineering, and device fabrication processes. However, further improvement in efficiency remains a daunting challenge due to limited light absorption and charge collection in the conventional device architectures. Advanced light manipulation is extremely attractive for applications in OSCs to enhance light harvesting efficiency. In addition, the photogenerated charge recombination should be reduced for enhancing the charge collection efficiency. Here, we proposed a nanopatterned ZnO:Al₂O₃ composite film as an efficient light and charge manipulation layer (LCML) to achieve high-efficiency single-junction OSCs of various material systems. The Al₂O₃ shells on ZnO nanoparticles offer the passivation effect that allows the optimal electron collection by suppressing charge recombination loss. The quasi-periodic nanostructures were imprinted into the ZnO:Al₂O₃ composite film for broadband self-enhanced light absorption, which was due to collective effects of the pattern-induced light scattering and surface plasmonic resonance. Correspondingly, the light harvesting efficiency of OSCs was dramatically enhanced with a peak external quantum efficiency up to 90% without sacrificing the charge transport properties. Highly efficient single-junction OSCs for different binary blends were then obtained, showing the certified PCEs of 9.69% and 13.03% for the fullerene blend of PTB7:PC₇₁BM and nonfullerene blend FTAZ:IDIC, respectively.
