Forecasting speculative stock prices is essential for effective investment risk management and requires innovative algorithms. However, the speculative nature, volatility, and complex sequential dependencies within financial markets present inherent challenges that necessitate advanced techniques. In this regard, a novel framework, ACB-XDE (Attenti...

The present article examines and compares the diverse online electoral advertising strategies employed by the Socialist Party (PS) and the Democratic Party (PD) in Albania’s national and municipal elections. The purpose of this study is to analyze the themes, communication techniques, and tones used in campaign advertising and to evaluate how these...

The rapid growth of the digital economy presents opportunities and challenges, particularly in the Gulf Cooperation Council (GCC) region, where economic diversification is essential. Accurate measurement of digital economic activity is crucial for developing effective policies and strategic decision-making. This study introduces a comprehensive Dig...

Entrepreneurship education has evolved to meet the demands of a dynamic business environment, necessitating innovative teaching methods to prepare entrepreneurs for market uncertainties. Large Language Models (LLMs) like the Generative Pre-trained Transformer 4 (GPT-4), recognized for their exceptional performance on public datasets, are examined i...

This paper explores the transformative potential of blockchain technology (BT) as a catalyst for sustainable development, addressing the tri-fold aspects of environmental, economic, and social sustainability. Through a comprehensive review and theoretical framework, it delves into how BT can significantly contribute to achieving the United Nations...

Bayesian estimation of the linear regression parameter system is considered by deploying Median Rank Set Sampling (MRSS). The full conditional distributions and the associated posterior distribution are obtained. Therefore, based on Markov Chain Monte Carlo simulation, the Bayesian point estimates and credible intervals for the regression parameter...

The transportation sector accounts for 61.5% of global oil consumption and is responsible for 29% of the world’s total energy demand. Passenger transportation utilizes around 50%–60% of the energy used for transportation-related activities. Accurate prediction of future transportation energy consumption is essential for governments to make well-inf...

The term “Internet of Things” (IoT) refers to an architecture in which digital objects have identification, sensing, connectivity, and processing capabilities that allow them to connect with other devices as well as perform tasks on the internet. There are many applications of IoT, among which Vehicle Delay-Tolerant Networks (VDTNs) are one of the...

The increasing demand for bandwidth and long-haul transmission has led to new methods of signal processing and transmission in optical fiber communication systems. The nonlinear Fourier transform is one of the most recent methods proposed, and is able to represent an integrable nonlinear Schrödinger equation (NLSE) channel in terms of its continuou...

Northern Alps are situated in a mountainous block in the Northern Albania region, in counties Shkoder and Kukes. The terrain formation has created isolated communities from the infrastructure point of view, thus leaving villages and valleys disconnected. In the modern world, connectivity remains as a must toward digitalization. The need for a monit...

A rural mountainous area, sparsely populated and unserved by the communications network and the electricity grid, but popular with tourists, is assessed for risk factors. The paper presents research undertaken for the Northern Albanian Alps, but applicable to any such similar areas, for the application of technology to assess, predict and prevent d...

Real time analysis of images is an inherent expectation of the medical imaging research area. Monitoringof important medical data requires the acquisition of high-quality images at a high rate. Nowadays manyexperiments are conducted on multiwell culture plates to determine the influence of different physical andchemical conditions on a specific bio...

A polarization multiplexed all-optical orthogonal frequency division multiplexing (AO-OFDM) system is investigated analytically and numerically, with 12.5 Gbaud symbol rate, that is compatible with the International Telecommunication Union flexible grid. We demonstrate that fast adaptive filtering is not require at the receiver and chromatic disper...

Iris recognition is a well-known biometric identification system which distinguishes authentic and imposter individuals based on the features of their irides. It employs stringent statistical analyses of the features of irides due to the fact that each person has a unique iris, just like a fingerprint. In this work, the approach adopted towards the...

A new coherent optical transmission system is proposed that makes use of the digital multicarrier fractional Fourier transform to obtain serial optical Nyquist pulses at the receiver side in the time domain by adopting the time-lens effect. Theoretical time-lens effect is derived based on fractional Fourier transform (FrFT) and chromatic dispersion...

In this study the electromagnetic field scattered by a buried object is obtained by use of a commercial full-wave frequency-domain solver which implements the Finite Element Method (FEM). The buried object is supposed to have different simple shapes and material composition such as a cylinder or cylindrical shell modelling for example a void in con...

We propose and test a coherent all-optical orthogonal frequency-division multiplexing (AO-OFDM) system, based on all-optical (de)multiplexing and coherent detection, for multiterabit per second (multi-Tbit/s) passive optical networks (PONs). The proposed approach allows us to greatly increase the downstream data rate per user and extend the standar...

An experimental comparison of all optical-orthogonal frequency division multiplexing (AO-OFDM) transmission is presented, using at the receiver either a fiber Bragg grating (FBG) or an arrayed waveguide gratings (AWG). System performances are analyzed, without dispersion compensation or optical time gating.

We report on the transmission experiment of seven 12.5-GHz spaced all optical-orthogonal frequency division multiplexed (AO-OFDM) subcarriers over a 35-km fiber link, using differential quadrature phase shift keying (DQPSK) modulation and direct detection. The system does not require chromatic dispersion compensation, optical time gating at the rec...

We consider a simple and effective solution for unbundling the local loop in optical access networks, based on the orthogonal frequency division multiplexing technique, without coherent detection. The proposed architecture has a reduced power consumption and allows a flexible and scalable resource assignment among the operators and/or the users. Sy...
