Abstract:
Pulse shape discrimination is a name of a group of techniques used to detect and distinguish between different types of radiation interactions. Analog pulse shape discrimination methods can be more suitable than digital methods, for high-speed scintillators both from rate and power consumption perspectives. Common analog discrimination methods are based on pulse-height and pulse-energy discrimination techniques. Other techniques rely on the time difference in the pulse width such as the ZeroCrossing methods. Neither of the above combine both amplitude and time methods. We present a novel analog pulse shape discrimination topology that combines both height and time domain. The topology is based on discrimination according to the pulse duration in time combined with compensation function of the pulse height. Amplitude of the pulse is used as a restraining factor. Subsequently, our topology correctly identifies fast pulses that are prolonged in time due to their high amplitude. The topology yields superior discrimination capabilities, under degraded light collection conditions, with an uncertainty gap smaller than 1 ns in pulse width. The ability to control both the time and the amplitude parameters individually, provides tailored adjustment for various detectors and pulse shape discrimination applications.

Abstract:
Fifteen autosomal STR markers, namely D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, and FGA were typed using AmpFlSTR® Identifiler® Plus PCR amplification systems in 132 unrelated Santal individuals of Bangladesh. Forensic efficiency parameters like, matching probability (MP), power of discrimination (PD), polymorphism information content (PIC), power of exclusion (PE), typical paternity index (TPI), observed heterozygosity (Hobs), and expected heterozygosity (Hexp) were calculated for all the loci. No deviations from Hardy-Weinberg equilibrium were detected for the loci after Bonferroni correction. The combined matching probability (MP), combined power of discrimination (PD) and combined power of exclusion (PE) for the 15 tested STR markers were 8.38 x 10-17, 0.999999998 and 0.0.999993866, respectively. A comparison of the locus wise allele frequencies of autosomal STR data of the Santal population with the published geographically close population data based on Nei’s genetic distance revealed that the Santal population is closely related to Munda population from Jharkhand, India.

Abstract:
<p>Chaos discrimination is a prerequisite for the application of chaos theory modeling. Since the average orbital period of an air traffic flow system is long, it is difficult to obtain time series with a small time scale and many data points, so the Small-Data Method is often adopted to quantitatively calculate the chaotic characteristic quantity. However, when using the power spectrum method, it is found that the Small-Data Method is prone to false judgments when the data volume is small. To reduce spurious judgments, we apply a chaos discrimination algorithm based on an Improved Alternative Data Method combined with the Small-Data Method for air traffic flow and analyze it by example. The algorithm was experimentally demonstrated to correct the false judgment results of the Small-Data Method. In particular, when the data volume is only 150, the discrimination accuracy of the improved algorithm is as high as 80%, which is 26% higher than the discrimination accuracy of the Small-Data Method. Moreover, the improved algorithm has better discriminative performance than the Small-Data Method under the same data volume condition, which is suitable for the chaotic discriminative analysis of the arrival traffic flow time series.</p> <p> </p>

Abstract:
SUMMARYAn index of discrimination was used to assess the discriminatory power of biotyping for salmonellas of selected serotypes. Three collections of phage-typed strains ofSalmonella typhimuriumandSalmonella paratyphiB, previously tested for biotype, were examined. The results established that the discrimination index was high when full biotyping alone was used for differentiation of strains from international series. When biotyping was combined with phage typing, the discrimination achieved was greater than for either method used alone. These findings confirm that biotyping affords excellent discrimination of strains ofS. typhimuriumandS. paratyphiB and indicate that the results obtained from biotyping can be interpreted with confidence.

AbstractThis study evaluates the forensic utility of the 30 insertion and deletion (indel) markers contained in the Qiagen Investigator® DIPplex kit in the Kuwaiti population (n = 150). All but one of the 30 markers were shown to conform to the expectations of the Hardy-Weinberg Equilibrium. Linkage disequilibrium tests showed no statistically significant deviation from independence. The high combined power of discrimination (CPD > 99.999%) and low combined match probability (CMP) of 2.736 × 10−13 provide a satisfactory level of discrimination, allowing the DIPplex loci to be used as forensic markers for individual identification in Kuwait. The paternity indices indicate the usefulness of the DIPplex kit as a supplementary typing system for challenging paternity cases in Kuwait.

Abstract:
Azerbaijan population consisting of 302 individuals was studied using 15-STR markers constituting the main set of human identification, and for each STR locus the forensic and population-genetic parameters were determined. Along with the other parameters, the calculated P-values (PHWE) for the accuracy of the Hardy- Weinberg equilibrium (HWE) tests showed that for our population this parameter had a statistically significant value (PwA=0.0006) only for the vWA locus. The values of parameters for a set of 15 STR loci such as the combined power of exclusion (CPE-0.99999935), combined power of discrimination (CPD-0.9999999999999999965), combined paternity index (CPI-1466339.18) and the probability of paternity (PP-0.99999932) showed that given set of loci can be confidently used in ving of identification our population the D21S11. D2S1338, D18S51 and FGA STR markers are more informative. In addition, comparative analysis of our population with 14 world populations based on the allelic composition of STR markers, allelic frequencies and basic population-genetic parameters have established that there are some degree of differences in the allelic structure of individual loci and the frequencies of the identified alleles between the compared populations. Significant differences are observed both in the region of the most frequent major and in the region of low-frequency minor alleles of STR markers.

Abstract:
To investigate the genetic polymorphisms of 19 X-STR loci in the Han population in Northern China, samples from 628 unrelated individuals (314 males and 314 females) were collected and 19 X-STR loci were amplified by AGCU X19 STR System. A total of 270 different alleles were detected in 19 X-STR loci. All loci were in Hardy − Weinberg equilibrium and there was only one pair of linkage loci (DXS10103-DXS10101). There was no significant difference in allele frequency between male and female populations. The combined power of discrimination in males was 1–1.8667 × 10−13, while the combined power of discrimination in females was 1–3.6532 × 10−22. The combined mean paternity exclusion chance (CMEC) for X-chromosomal markers in father/daughter or mother/son duos Mean paternity exclusion chance (MECDesmarais Duo) was 1–5.1109 × 10−9. Moreover, the CMEC for X-chromosomal markers in trios involving daughters (MECDesmarais) was 1–2.0292 × 10−12. The compound amplification system composed of 19 X-STR in this study showed high polymorphism in the Han population of Northern China, which had a high application value in difficult genetic relationship identification.

Abstract:
The aim of this study was to develop models based on linear dimensions or shape factors, and the sets of combined linear dimensions and shape factors for discrimination of sour cherry pits of different cultivars (‘Debreceni botermo’, ‘Łutówka’, ‘Nefris’, ‘Kelleris’). The geometric parameters were calculated using image processing. The pits of different sour cherry cultivars statistically significantly differed in terms of selected dimensions and shape factors. The discriminative models built based on linear dimensions produced average accuracies of up to 95% for distinguishing the pit cultivars in the case of ‘Nefris’ vs. ‘Kelleris’ and 72% for all four cultivars. The average accuracies for the discriminative models built based on shape factors were up to 95% for the ‘Nefris’ and ‘Kelleris’ pits and 73% for four cultivars. The models combining the linear dimensions and shape factors produced accuracies reaching 96% for the ‘Nefris’ vs. ‘Kelleris’ pits and 75% for all cultivars. The geometric parameters with high discriminative power may be used for distinguishing different cultivars of sour cherry pits. It can be of great importance for practical applications. It may allow avoiding the adulteration and mixing of different cultivars.

Abstract:
While it is undeniable that over-reliance on AI-powered digital media has created a shift in epistemological understandings of how communication shapes, and is shaped by, the affordances of AI processes and power relations, it is equally true that the latest technologies function as multimodal resources for meaning-making with the danger of offering fertile ground for new forms of discrimination. The present study argues that AI-coded search engines function as semiotic resources where the interaction of the verbal and the visual communicates corporate interests and human bias that ultimately lead to structural gender- and sex-based discrimination. The aim of this study is to advance awareness on algorithmic discrimination by investigating asymmetric power relations and discriminatory frameworks in the combined visual/verbal representation of same-sex couples in Google Images from the vantage point of Multimodal Critical Discourse Analysis. The comparative analysis concerns the Italian and the British digital landscape of Google Images, where same-sex couples are intended as a socio-culturally stigmatized group. The examination uncovers different levels of structural gender- and sex-based discrimination in Google Images computations of verbal and visual resources, whose final output are thumbnail captioned images. The latter are intended as multimodal ensembles representing how same-sex couples epitomize gender- and sex-based discrimination in Google Images digital landscape. Since the results of the queries are highly context-dependent, the comparison of the Italian and the British digital landscapes encodes different discriminatory frameworks and power asymmetries that should prompt effective measures to contrast the perils of heteronormative bias in AI-based search engines.

Abstract:
Parkinson's disease is known to be associated with abnormal electrical spiking activities of basal ganglia neurons, including changes in firing rate, bursting activities and oscillatory firing patterns and changes in entropy. We explored the relative importance of these measures through optimal feature selection and discrimination analysis methods. We identified key characteristics of basal ganglia activity that predicted whether the neurons were recorded in the normal or parkinsonian state. Starting with 29 features extracted from the spike timing of neurons recorded in normal and parkinsonian monkeys in the internal or external segment of the globus pallidus or the subthalamic nucleus (STN), we used a method that incorporates a support vector machine algorithm to find feature combinations that optimally discriminate between the normal and parkinsonian states. Our results demonstrate that the discrimination power of combinations of specific features is higher than that of single features, or of all features combined, and that the most discriminative feature sets differ substantially between basal ganglia structures. Each nucleus or class of neurons in the basal ganglia may react differently to the parkinsonian condition, and the features used to describe this state should be adapted to the neuron type under study. The feature that was overall most predictive of the parkinsonian state in our data set was a high STN intraburst frequency. Interestingly, this feature was not correlated with parameters describing oscillatory firing properties in recordings made in the normal condition but was significantly correlated with spectral power in specific frequency bands in recordings from the parkinsonian state (specifically with power in the 8–13 Hz band).

Abstract:
An investigation into the performance of several combined gas-steam power generating plants’ cycles was undertaken at the School of Engineering and Technology at the University of Hertfordshire and it is predominantly analytical in nature. The investigation covered in principle the aspect of the fundamentals and the performance parameters of the following cycles: gas turbine, steam turbine, ammonia-water, partial oxidation and the absorption chiller. Complete thermal analysis of the individual cycles was undertaken initially. Subsequently, these were linked to generate a comprehensive computer model which was employed to predict the performance and characteristics of the optimized combination. The developed model was run using various input parameters to test the performance of the cycle’s combination with respect to the combined cycle’s efficiency, power output, specific fuel consumption and the temperature of the stack gases. In addition, the impact of the optimized cycles on the generation of CO2 and NOX was also investigated. This research goes over the thermal power stations of which most of the world electrical energy is currently generated by. Through which, to meet the increase in the electricity consumption and the environmental pollution associated with its production as well as the limitation of the natural hydrocarbon resources necessitated. By making use of the progressive increase of high temperature gases in recent decades, the advent of high temperature material and the use of large compression ratios and generating electricity from high temperature of gas turbine discharge, which is otherwise lost to the environment, a better electrical power is generated by such plant, which depends on a variety of influencing factors. This thesis deals with an investigation undertaken to optimize the performance of the combined Brayton-Rankine power cycles' performance. This work includes a comprehensive review of the previous work reported in the literature on the combined cycles is presented. An evaluation of the performance of combined cycle power plant and its enhancements is detailed to provide: A full understanding of the operational behaviour of the combined power plants, and demonstration of the relevance between power generations and environmental impact. A basic analytical model was constructed for the combined gas (Brayton) and the steam (Rankine) and used in a parametric study to reveal the optimization parameters, and its results were discussed. The role of the parameters of each cycle on the overall performance of the combined power cycle is revealed by assessing the effect of the operating parameters in each individual cycle on the performance of the CCPP. P impacts on the environment were assessed through changes in the fuel consumption and the temperature of stack gases. A comprehensive and detailed analytical model was created for the operation of hypothetical combined cycle power and power plant. Details of the operation of each component in the cycle was modelled and integrated in the overall all combined cycle/plant operation. The cycle/plant simulation and matching as well as the modelling results and their analysis were presented. Two advanced configurations of gas turbine cycle for the combined cycle power plants are selected, investigated, modelled and optimized as a part of combined cycle power plant. Both configurations work on fuel rich combustion, therefore, the combustor model for rich fuel atmosphere was established. Additionally, models were created for the other components of the turbine which work on the same gases. Another model was created for the components of two configurations of ammonia water mixture (kalina) cycle. As integrated to the combined cycle power plant, the optimization strategy considered for these configurations is for them to be powered by the exhaust gases from either the gas turbine or the gases leaving the Rankine boiler (HRSG). This included ChGT regarding its performance and its environmental characteristics. The previously considered combined configuration is integrated by as single and double effect configurations of an ammonia water absorption cooling system (AWACS) for compressor inlet air cooling. Both were investigated and designed for optimizing the triple combination power cycle described above. During this research, tens of functions were constructed using VBA to look up tables linked to either estimating fluids' thermodynamic properties, or to determine a number of parameters regarding the performance of several components. New and very interesting results were obtained, which show the impact of the input parameters of the individual cycles on the performance parameters of a certain combined plant’s cycle. The optimized parameters are of a great practical influence on the application and running condition of the real combined plants. Such influence manifested itself in higher rate of heat recovery, higher combined plant thermal efficiency from those of the individual plants, less harmful emission, better fuel economy and higher power output. Lastly, it could be claimed that various concluding remarks drawn from the current study could help to improve the understanding of the behaviour of the combined cycle and help power plant designers to reduce the time, effort and cost of prototyping.

Abstract:
In order to reach targets on reducing greenhouse gas emissions from fossil resources it is necessary to reduce energy losses in production processes. In polygeneration, several processes are combined to complement each other to avoid sub-optimization of the standalone processes. This thesis addresses polygeneration with focus on Combined Heat and Power (CHP) production integrated with other processes. Biomass-fired CHP plants are commonly dimensioned to have surplus heat production capacity during periods with lower heat demand. At the same time, production of biomass based vehicle fuels and fuel upgrading are heat demanding processes. The opportunity to combine CHP with ethanol production from lignocellulosic feedstock and torrefaction with the aim of replacing fossil fuels are used as cases during the evaluation of polygeneration. Simulation models are used to investigate the performance of CHP integrated with production of ethanol and torrefaction. Measured data from commercial CHP plants have been used to reflect the operation boundaries. The findings show that polygeneration can compete with stand-alone production in both energy and economic performance. Polygeneration offers a wider operating range where reduced minimum load gives increased annual operating time. Therefore, under limited heat demand more renewable electricity production is possible due to increased operating hours and steam extraction from the turbine during part-load operation. Resource availability and fluctuations in fuel price have the largest impact on the profit of polygeneration. Other aspects that have substantial effects on the economy in polygeneration are the electricity spot price and subsidies. Furthermore, it has been proven that the yield of each product in a multiproduct process plant, the size of the plant and the heat demand have a large impact on the economy. Polygeneration turns by-products into buy-products.

Abstract:
Simulators for power plants can be used for many different purposes, like training for operators or for adjusting control systems, where the main objective is to perform a realistic behaviour for different operating conditions of the power plant. Due to an increased amount of variable energy sources in the power system, the role of the operators has become more important. It can therefore be very valuable for the operators to try different operating conditions like island operation. The aim of this thesis is to model the power system of a general combined-cycle power plant simulator. The model should contain certain components and have a realistic behaviour but on the same time be simple enough to perform simulations in real time. The main requirements are to simulate cold start, normal operation, trip of generator, a controlled change-over to island operation and then resynchronisation. The modelling and simulations are executed in the modelling software Dymola, version 6.1. The interface for the simulator is built in the program LabView, but that is beyond the scope of this thesis. The results show a reasonable performance of the power system with most of the objectives fulfilled. The simulator is able to perform a start-up, normal load changes, trip of a generator, change-over to island operation as well as resynchronisation of the power plant to the external power grid. However, the results from the changing-over to island operation, as well as large load losses during island operation, show an unreasonable behaviour of the system regarding the voltage magnitude at that point. This is probably due to limitations in calculation capacity of Dymola, and the problem has been left to further improvements due to lack of time. There has also been a problem during the development of a variable speed regulated induction motor and it has not been possible to make it work due to lack of enough knowledge about how Dymola is performing the calculations. Also this problem has been left to further improvements due to lack of time.

Abstract:
As electricity production from renewable sources increases, higher flexibility is required by fossil fuel generation to cope with the inherent fluctuations of solar and wind power. This results in shorter operating cycles and steeper ramps for the turbines, and more uncertainty for the operators. This thesis work applies mathematical optimization and statistical learning to improve the economic dispatch of a combined cycle power plant composed by two separate blocks of two gas turbines and one steam turbine. The goal is to minimize the input fuel to the gas turbines while respecting a series of constraints related to the demand the plant faces, power generation limits etc. This is achieved through the creation of a mathematical model of the plant that regulates how the plant can operate. The model is then optimized to reduce fuel consumption at a minimum. Machine learning techniques have been applied to sensor data from the plant itself to realistically simulate the behavior of the turbines. Input-Output curves have been obtained for power and exhaust heat generation of all the turbines using ordinary least squares on monthly data with a ten minutes sampling rate. The model is cross-validated and proven statistically valid. The optimization problem is formulated through generalized disjunctive programming in the form of a mixed-integer linear problem (MILP) and solved using a branch-and-bound algorithm. The output of the model is a one-week dispatch, in fifteen minutes intervals, carried out for two months in total. Lower fuel consumption is achieved using the optimization model, with a weekly reduction of fuel consumed in the range of 2-4%. A sensitivity analysis and a correlation matrix are used to highlights the demand and the maximum available capacity as critical parameters. Results show that the most efficient machines (alternatively, the ones with highest available capacity) should be operated at maximum load while still striving for an efficient utilization of the exhaust gas.<br>När elproduktionen från förnybara källor ökar krävs högre flexibilitet av fossil bränsleproduktion för att hantera fluktuationerna från sol- och vindkraft. Detta resulterar i kortare driftscykler och brantare ramper för turbinerna och mer osäkerhet för operatörerna. Detta avhandlingsarbete tillämpar matematisk optimering och statistisk inlärning för att förbättra det ekonomiska utnyttjandet av en kombicykel i ett kraftverk som består av två separata block med två gasturbiner och en ångturbin. Målet är att minimera bränsleförbrukningen hos gasturbinerna samtidigt som man tar hänsyn till en serie av villkor relaterade till efterfrågan som anläggningen står inför, kraftproduktionsbegränsningar etc. Detta uppnås genom skapandet av en matematisk modell för anläggningen som reglerar hur anläggningen kan fungera. Modellen är sedan optimerad för minsta möjliga bränsleförbrukning. Maskinteknik har använts på sensor data från själva anläggningen för att realistiskt simulera turbinernas beteende. In och utdata kurvor har erhållits för kraftproduktion och avgasvärmeproduktion med hjälp av ordinary least squares (OLS) med månads data och med en tio minuters samplingshastighet. Modellen är korsvaliderad och bevisad statistiskt giltig. Optimeringsproblemet formuleras genom en generaliserad disjunktiv programmering i form av ett mixed-integer linear problem (MILP) och löses med hjälp av en Branch-and-Bound algoritm. Resultatet från modellen är en veckas värden, med femton minuters intervall, totalt i två månader. Lägre bränsleförbrukning uppnås med hjälp av optimeringsmodellen, med en vecka minskad bränsleförbrukning i intervallet 2-4%. En känslighetsanalys och en korrelationsmatris används för att visa efterfrågan och den maximala tillgängliga kapaciteten som kritiska parametrar. Resultaten visar att de mest effektiva maskinerna (alternativt de med högsta tillgängliga kapacitet) bör drivas med maximal belastning medan de fortfarande strävar efter ett effektivt utnyttjande av avgaserna.

One such approach is to create a transactive market for DER to provide grid services, which are services required to support reliable grid operation. Though work has been done to understand some of the technical mechanisms of this type of market, gaps still exist in understanding the value and market opportunity of ancillary services at the distribution level. One type of ancillary service - reactive power - is of particular interest because of the theoretic ability to source from existing assets on the distribution network. This paper aims to build understanding of the value of procuring reactive power from one of these assets: Combined Heat and Power (CHP) systems. The value of procuring reactive power from a CHP system will be quantified by 1) characterizing CHP systems' capacity to produce and absorb reactive power, 2) assessing the annual cost of procuring reactive power from CHP systems, and 3) comparing the CHP system technical capability and cost to the utility's conventional solution: capacitor banks. This study finds that, while there are promising scenarios in which CHP systems can technically and economically provide reactive power in a comparable or slightly advantaged manner to capacitor banks, the overall statistics for the 29 CHP systems analyzed in the New York fleet do not conclusively demonstrate an advantage that supports outright replacement of capacitor banks. Further assessment of CHP systems as a complementary source of reactive power and site-specific case studies are recommended to inform the next step in the decision making process for determining whether this path should be pursued as a source of reactive power.<br>by Monica Harnoto.<br>M.B.A.<br>S.M.<br>M.B.A. Massachusetts Institute of Technology, Sloan School of Management<br>S.M.

Abstract:
Women are up to twice as likely to suffer from post-traumatic stress disorder (PTSD) than men. Failure to discriminate between cues predicting threat and safety is associated with PTSD, yet sex differences in fear discrimination remain poorly understood. Here, we examined sex differences in auditory fear discrimination in rats using a combination of behavioural, computational and electrophysiological methods. In the initial behavioural study, males and naturally cycling females underwent 1-3 days of discrimination training, consisting of pairings of one tone (CS+) with shock and presentations of another tone (CS-) alone. After one day of training, females, but not males, discriminated between the CS+ and CS-. With 2-3 days of training, however, males discriminated and females generalised between the CS+ and CS-. Further testing also revealed that males successfully encode the CS- as a safety signal, whereas females do not. Using reduced computational models, we investigated how both ‘discrimination’ and ‘generalisation’ phenotypes can be generated in silico. We achieved this through a simulation of neural activity produced via ‘fear’ and ‘safety’ neural sub-populations of the basolateral amygdala (BLA) in response to CS+ and CS- cues. By using a model representation of extended fear discrimination training and retrieval, we found that generalisation between the CS+ and CS- could be produced from reduced inhibition, or increased excitation, of fear neurons. Due to their involvement in regulating learned fear, we additionally aimed to investigate the roles of the prelimbic (PL) and infralimbic (IL) cortices of themedial prefrontal cortex in fear discrimination. By concurrently recording activity from the PL, IL and BLA in awake behaving animals during retrieval of the CS+ and CS- after extended discrimination training, we examined the individual contributions and functional interactions of these regions during this learning paradigm. We found that, in males, the PL showed an increase in power at both theta (4-12 Hz) and gamma (30-120 Hz) frequencies during presentations of the CS- compared to the CS+, whereas this increase was largely absent in females. Taken together, these results indicate that, while females show fear discrimination with limited training, they generalise with extended training. We hypothesised that this generalisation in females is likely due to impaired safety learning, which may result, in part, from sex differences in the neural circuitry underlying fear discrimination.

Abstract:
An attractive technique for increasing the coherent output from semiconductor lasers is to coherently combine the output powers from individual high power single transverse mode lasers in an external Talbot cavity. In this presentation we report on the first demonstration of CW coherent high output power from a GaAlAs semiconductor laser array in a Talbot cavity. The cavity consists of an anti reflection coated 20 element laser diode array on 50 microns spacing, an imaging system and a 50% reflective flat output mirror. The chosen fill factor of the array optimizes mode discrimination and coupling between the lasers while minimizing the diffraction losses due to light diffracted out of the array. A half Talbot length cavity (round trip) is used such as to alleviate the need of a spatial filter in the cavity. Our experimental results show a CW diffraction limited far field of 250 mW and a differential efficiency of 29%. These power levels surpasses by far previous power levels obtained with semiconductor laser arrays in a Talbot cavity. Our results are found to be in good agreement with our theoretical model.

Abstract:
We present a new servo controllable force sensor that exploits photon momentum forces for the identification, calibration, and control of its dynamic properties. The sensor comprises a millimeter-scale glass cantilever, a low-noise fiber interferometer for detection of the cantilever deflection, and a high-power, intensity-modulated fiber laser to apply optical actuation forces. Combined with appropriate digital and analog signal processing, the sensor has been operated as a feedback-cooled low-noise force sensor, and as a self-excited oscillator governed by the familiar Rayleigh equation. Operated in this self-excited Quber mode, it appears well suited for noncontact, frequency modulated force gradient detection such as in atom discrimination. Here, we briefly lay out the principles of the sensor and provide examples of its performance, including the demonstration of feedback cooling and the ability to induce controlled limit cycle oscillations with atomic scale amplitudes.

Abstract:
This article is devoted to a philosophical study of the transformation of power in the context of digital immortality - a hypothetical possibility of transferring human consciousness into a digital environment and achieving potentially infinite existence. Digital immortality is considered as a factor capable of radically changing the balance of power in society and giving rise to new forms of power, control and social interaction. The article examines the factors limiting access to digital immortality technology, such as high cost, technological complexity and ethical considerations. The social and political consequences of unequal access are analyzed, including the increase in social inequality and the emergence of a “digital divide” - a gap in access to immortality itself. The role of data in ensuring digital immortality and the problem of ownership and control over the personal data of “immortal” individuals are considered. Particular attention is paid to the risks of data abuse, manipulation of consciousness and violation of privacy. The changes in the balance of power between the “immortals” and “mortals” are analyzed, as well as the emergence of new forms of social hierarchy and discrimination. The potential for conflict and social instability associated with inequality and the struggle for resources is explored. The article uses an interdisciplinary approach that combines methods from the philosophy of technology, social philosophy, political philosophy and ethics. The analysis is based on a critical understanding of classical and contemporary philosophical theories, as well as on the study of modern trends in the development of technologies and their potential impact on society.
