Published: September 2022

Abstract
Wireless Power Transfer (WPT) technology has recently gained popularity in applications and research topics. It enables the transfer of electrical energy from a source to a load without connecting wires physically. The WPT system is commonly studied classically using integer order capacitors and inductors. Nonetheless, such integer order based systems have drawbacks, such as low output power, poor transmission efficiency and sensitivity to parameter variations. This paper proposes a fractional order resonant WPT circuit whereby both the transmitting and receiving ends are composed of a fractional capacitor and inductor to overcome such problems. In this paper, the overall performance is studied based on its output power and efficiency considering a series-parallel topology. The effect of fractional order in fractal elements will be analyzed to observe the optimal combination of components to achieve the maximum output power with higher efficiency. Through a comparative analysis of the results, several combinations of circuit parameters can provide a theoretical understanding for implementing an experimental system.
A potential flooding version number attack against RPL based IOT networks

Published: September 2022

Abstract
Routing protocol for low power and lossy networks (RPL) has been proposed for power, memory, and processing constrained devices. Owing to their constrained, RPL-based networks are exposed to a wide range of security attacks that mainly include control message tampering. In this paper we propose and study a modified version number attack, based on flooding the network by falsified incremented version numbers. The obtained results show that the modified attack led to an immense increase in the overhead, 1426%, compared with the attack-free case, and an increase of 182 % in the total energy consumption. When it comes to PDR a degradation to 4.7% has been recorded, affecting the reliability of the network. On the other hand, the latency also showed an increase from 0.24 s in the attack-free case to 0.89 s, which is mainly due to the high congestion created by the attack.

Published: September 2022

Abstract
Quantum-dot Cellular Automata (QCA) is a rival to complementary-metal-oxide-semiconductor (CMOS)-based technology and one of the most cutting-edge nano-scale technologies. The multiplexer is a fundamental component in the fields of nano communication and nano computation. The investigative item of this article is the QCA multiplexer, and a handful of the best multiplexers were chosen as samples for the current experiment. The QCA layouts were designed in the QCADesigner-2.0.3 simulation engine environment, and the best one was reported after successfully experimenting on a total of eight samples. The co-ordinate-based energy was estimated using QCADesigner-E (QDE), and the non-adiabatic energy waste was investigated using QCAPro. According to the coordinates-based technique, the overall energy waste of the best energy-saving QCA multiplexer is 5.90 meV, with an average energy loss per cycle of 0.537 meV. Another approach, QCAPro-based, was used to estimate the energy loss at three different levels of tunneling at a constant temperature, yielding an overall energy loss of approximately 12 to 15 meV for the energy-efficient multiplexers..

AbstractChannel equalization is the efficient method for recovering distorted signal and correspondingly reducing bit error rate (BER). Different type of equalizations, like feed forward equalization (FFE) and decision feedback equalization (DFE) are canceling channel effect and recovering channel response. Separate optimization of tap coefficients for FFE and DFE does not give optimal result. In this case FFE and DFE tap coefficients are found separately and they are not collaborating. Therefore, the final equalization result is not global optimal. In the present paper new analytical method for finding best tap coefficients for FFE and DFE joint equalization is introduced. The proposed method can be used for both NRZ and PAM4 signals. The idea of the methodology is to combine FFE and DFE tap coefficients into one optimization problem and allow them to collaborate and lead to the global optimal solution. The proposed joint optimization method is fast, easy to implement and efficient. The method has been tested for several measured channels and the analysis of the results are discussed.

Abstract

Introduction: The creation of an abdominal stoma is a common procedure performed by surgeons as a part of the treatment for benign and malignant conditions in general surgery. Stoma formation is simple, but sometimes the associated postoperative complications have an impact on the patients’ physical and psychological state. The majority of complications do not require reoperation, but when it is indicated, we have to assess the most appropriate option for the patient.

Material and Methods: We conducted a retrospective study in a single surgical center, the Department of Surgery, Mureș County Hospital, Târgu Mureș, Romania, using data from patients who have been admitted under elective conditions for stoma-related complications between 2005 and 2019.

Results: A total number of 877 ostomies (653 colostomies and 224 ileostomies) were performed, and 157 patients (17.9%) developed some type of stoma complication and required surgical intervention. The mean age was 64.5 ± 2.1 years, with a male-female ratio of 1.3 to 1. The leading comorbidities included cardiovascular disease (52.2% of cases), obesity (22.2%), and diabetes (18.4%). Parastomal hernia was the most frequent complication (47.5% of cases), followed by stoma prolapse (23.4%), parastomal stenosis (20.3%), and parastomal infection (8.2%). There was an association between age and the type of complication: parastomal hernia, stoma prolapse, and stenosis were more frequent in the elderly; parastomal infection was more prevalent in young patients. A longer hospital stay was observed in case of parastomal hernia.

Conclusions: Stoma formation is associated with significant morbidity. Typically, the complications appear in the elderly. Conservative treatment is essential, but some of the late complications, such as parastomal hernia, stoma stenosis, stoma prolapse, and parastomal infection, require a surgical solution. Parastomal hernias are the most common complications, frequently associated with comorbidities and prolonged hospitalization.
Remote-sensing detection of points for the heavy vehicles crossing in the large lowland riverbeds
Authors: Ostrowski Piotr 
Published: September 2022

Abstract
The erosion-resistant culminations of the alluvial subsoil occurring in the riverbeds of some rivers may play the role of “geological bridges” under favorable hydrological conditions, constituting places convenient for forcing by heavy vehicles. The article discusses the possibility of remote-sensing identification of such places based on a common analysis of aerial images, high-resolution satellite images and Digital Terrain Models based on Airborne Laser Scanning. The result of the work was the identification of relief forms in the valley bottoms of large lowland indicating the available locations for heavy vehicles forcing the bed. This allowed for the formulation of general assumptions of the SYSTEM OF DESIGNING ZONES CONVENIENT FOR CROSSROADS USING AIR PLATFORMS.

Identification of Regularities in Relation Between Prices on Primary and Secondary Housing Market in Selected Cities in Poland
Authors: Kokot Sebastian 
Published: September 2022

Abstract
The purpose of this study is to identify regularities in the price relations between primary and secondary housing markets. The primary market and the secondary market are two related but quite differentiated sub-segments of the residential market. They particularly differ in the qualitative features of their traded objects and, consequently, also in the prices recorded in their trading. Nevertheless, they remain under the influence of the same main factors of a macroeconomic nature. This gives rise to the research hypothesis that prices of flats quoted in the sub-segments of the residential market remain in specific relationships with one another.
In an attempt to verify this hypothesis, the paper presents the results of an analytical work on the search for regularities in the relationship between prices on primary and secondary housing markets in selected Polish cities. The regularities concern the dynamics and structure of price relation indices constructed for the research. They also include classification analyses. The findings of the research have revealed, inter alia, that in the majority of the cities under study, prices of flats in the primary markets are higher than prices in the secondary markets. However, situations in which the reverse happens periodically (sometimes occasionally) are not rare. The examined relations are not permanent and are subject to relatively large, irregular fluctuations over time. It is possible to distinguish groups of cities which are relatively similar in this respect, but these similarities are not strong.
Econometric Models of Real Estate Prices with Prior Information. Mixed Estimation
Authors: Doszyń Mariusz 
Published: September 2022

Abstract
The purpose of this paper is to estimate econometric models with sample and prior information. Prices of land property for residential development in Szczecin are modeled (the price level was determined for 2018). Modeling property prices only based on sample data generates numerous problems. Transaction databases from local real estate markets often contain a small number of observations. Properties are frequently similar, which results in low variability of property characteristics, and thus – low efficiency of parameter estimators. In such a situation, the impact of some features cannot be estimated from the sample data. As a solution to this problem, the paper proposes econometric models that consider prior information. This information can be, for example, in the form of property feature weights proposed by experts. The prior information will be expressed in the form of stochastic restrictions imposed on the model parameters. In the simulation experiment, the predictive power of mixed estimation models is compared with two kind of models: OLS models and model with only prior information. It turned out that mixed estimation results are superior with regard to formal criteria and predictive abilities.

Seed priming with zinc increases the seed germination and seedling growth of many crops. The present study aimed to investigate the effect of seed priming with different levels and sources of zinc on seed germination and seedling growth of barnyard millet variety MDU1. A germination experiment was conducted with various Zn sources and concentrations viz., T1- Non-primed seeds (control); T2-water priming; T3-GA3 priming; T4-T6: seed priming with 0.10%, 0.25% & 0.50% ZnSO4 ; T7- T9: seed priming with 0.10%, 0.25% & 0.50% Zn EDTA; T10-T12: seed priming with 0.10%, 0.25% & 0.50% Zn citrate and the experimental design was a completely randomized design (CRD) which were replicated five times. The seeds of MDU1 variety were treated with different sources and levels of Zn for 12h and the seed germination study was carried out for 15 days. After 15 days, the germination percentage, speed of germination, germination energy, germination index and the seedling growth parameters such as, root length, shoot length, vigour index and seedling dry weight were recorded. Seed priming with 0.50% ZnSO4 performed better in increasing the germination percentage (99%), speed of germination (76.2%), germination energy (69.4%), germination index (3.91) and seedlings growth parameters like shoot length (14.7cm), root length (16.5cm), seedlings dry weight (0.44g), vigour index I (3099) and II (44.6), Zn content (21.9 mg kg-1) & its uptake (5.54 mg g-1). This was closely followed by seed priming of Zn EDTA at 0.25% and Zn citrate at 0.50%. From this study, it can be concluded that seed priming with 0.50% ZnSO4 could be used to improve the germination and seedling growth of barnyard millet which was also economical.
