Abstract: The recent development in person re-identification has challenging task for variations in pose, illumination, expression, and also similar appearance between two different persons. In this paper, we propose Discrete Wavelet Transform (DWT) based person re-identification using Generative Adversarial Network (GAN). The CMU multi-PIE face database with multiple viewpoints and illuminations is considered to test the model. The profile side view face images to be tested are converted into frontal face images using Two-pathway generator adversarial network (TP-GAN). The frontal face images are loaded into the server to create server database. The synthesized TP-GAN images and server database images are pre-processed to convert RGB into grayscale images and also to convert into uniform face image dimensions. The person re-identification is based on feature extraction through DWT, which generates one low frequency LL band and three high frequency bands LH, HL and HH. The LL band coefficients are considered as final features, which are noise-free and compressed number of features. The features of profile side view images and server database images are compared using Normalized Euclidean Distance (NED) and threshold values for person re-identification.

Abstract: This article presents 24 sectors direct torque control (DTC) with fuzzy hysteresis comparators for the doubly-fed induction motor (DFIM) using a three-level neutral point clamped (NPC) inverter. The designed DTC technique of the DFIM combines the advantages of the DTC strategy and fuzzy logic controller. The reaching conditions, stability, and robustness of the DFIM with the designed DTC technique are guaranteed. The designed DTC technique is insensitive to uncertainties, including parameter variations and external disturbances in the whole control process. Finally, the designed DTC technique with fuzzy hysteresis comparators is used to regulate the electromagnetic torque and the flux of the DFIM fed by the three-level NPC inverter and confirms the validity of the designed DTC technique. Results of simulations containing tests of robustness and tracking tests are presented.

Abstract: An Octagonal shaped Annular Ring pattern reconfigurable antenna is proposed for cognitive radio applications which gives Omni-directional and directional pattern at 1.3 GHz. The antenna has the frequency switching capability at 1.5 GHz, 3.2 GHz, 4.8 GHz and 6.8 GHz with the use of a single PIN diode. Further, the antenna is modified by inserting a slotted square shape in an octagonal ring. With the use of two diodes, the proposed antenna shows the pattern diversity at 3.2 GHz and 4.6 GHz with the gain of 6.23 dBi. Also, the antenna shows the frequency switching for 1.5 GHz, 3.1 GHz, 4 GHz, 4.3 GHz, 4.8 GHz and 6.8 GHz with the different states of the PIN diode. The proposed antennas can be used for RFID, S and C band applications.

Abstract: Across-sectional study was conducted in Asossa, Bambasi and Homosha District from July 2020 to November, 2021 with the objectives of estimating, the seroprevalence of bovine brucellosis and epidemiological associated factors, assess awareness/knowledge, attitudes and practice towards the zoonotic disease of the society on the socio-impact and the control methods of Anthrax, Brucellosis and Rabies in animal and human beings, and assess preliminary retrospective data of the disease in the study area. Of 384 serum sample examined, 9/384 (2.34%) were positive for bovine brucellosis. The high seroprevalence of the bovine brucellosis (9.75%) was recorded in Homosha woreda whereas the low prevalence of the disease (0.09%) was recorded in Bambasi woreda and it was significantly high (p<0.004).The highest seroprevalence (5.12 %) of brucellosis was recorded in animals >9 years old whilst the lowest prevalence (1.97 %) was recorded in animals 3->5 years of old and the association was not significant among the age groups. Slightly, higher prevalence was registered in female animals (2.56%) than in male animals (0 %), which was not found to be statistically significant (p>0.05).The highest prevalence of brucellosis (3.33%) was found in animals with poor body condition while the lowest (2.20 %) was recorded in animals with medium body conditions respectively, and the difference was insignificant (p>0.05).Cattle Brucellosis was recorded across the study kebeles with the highest prevalence of(14.28%)in Gumukebele whereas in Dabus, Mender (47, 48, 41, 43, 42), Sonka, Womba, Megele(49), Komoshiga (27 and 28), N/komoshiga, Selga (24), Amba14, and Megele (33) kebeles, the lowest brucellosis prevalence (0%) was recorded in the present study and the prevalence of brucellosis was not significant across the study sites. In Gumu, Dunga, Mutsakosa, Megele(39), Komoshiga(26), (14.28%, 5%, 9.09%, 2.27%, 3.03%) brucellosis prevalence was recorded in the studied kebeles respectively, but the association is not significant (P>0.05).In Asossa, Bambasi and Homosha selected kebeles, 340 respondent farmers, 34 animal health workers and health extensions, kebele leaders were interviewed and retrospective data, up on communicable animal diseases (rabies, anthrax and brucellosis) and the respondent rate was assessed in the study areas. The respondents were assessed for the existing problems in 34 selected kebeles, from community farmers, animal health workers, health extensions and kebele leaders. They were interviewed for their perception of communicable animaldisease occurrence, symptoms, causative agent, the possible factors contributing for the occurrence of problems, activities to be taken for control measures, habit of using animal product (milk, meat) and the risk /exposure groups, number of sick, died and their preference of treated cases were assessed, vaccination habit of dog, cattle, sheep and goats; number and duration of aborted ruminants; use of (aborted, anthrax suspected) animal products cases and pain felling situation; awareness of zoonotic disease and occurrence of acute and sudden killer cattle disease in the area were assessed in this study. According to Asossa, General hospital retrospective data, of the total 434 unspecified human cases, 272 male cases and 162 female victims cases were recorded in the 2018- 2021 year. The rabies in human cases were varies in age categories, that was 4, 38, 170, 133, 82, 7 cases were reported in <1yr, 1-4 yr, 5-14 yr, 15-29yr, 30-64 yr and >=65 years of age respectively. Therefore, based on the findings, appropriate recommendations were forwarded to reduce the impact of the zoonotic diseases in the study area. Evidence of brucellosis in various cattle and the associated human population illustrates the need for a coordinated One Health approach to controlling brucellosis so as to improve public health and livestock productivity.

Abstract: The study focused on the prospects and challenges of the use of multimedia instructional aids in teaching of Mathematics in Senior Secondary Schools within Minna Town. The objective of the study among others was to investigate the adequacy of multimedia facilities for teaching and learning Mathematics in secondary schools within Minna town. Four research questions were formulated to guide the study. Descriptive survey research design was adopted for the study. The population of the study comprised of all secondary school teachers within Minna town and a simple random sampling technique was used to select twenty (20) secondary schools from the population of study (consisting of private and public schools). A simple random sampling using simple balloting was also used to select five (5) teachers from each selected school. This gives a sample size of one hundred (100). Out of the 100 respondents that were given the instrument, only 80 were retrieved which gives a response rate of 80%. A well-structured questionnaire which was validated by three experts was used to collect data for the study. The Pearson’s Product Moment Correlation was carried out and a coefficient of 0.81 shows a very strong reliability for the instrument. The data collected from the study were analyzed using descriptive statistics. Findings from the study revealed that majority of the respondents do not have access to the multimedia resources in schools and that they did not make use of the multimedia resources in practical teaching. It is recommended among others that the Nigerian (federal) government and proprietors of private schools should support the teaching of Mathematics by allocating and releasing adequate funds to invest in massive Internet connectivity, as well as purchase and installation of ICT infrastructures in secondary schools.

Abstract. In this article, the leading axiom of providing quality education in the context of globalization is the presentation of theoretical knowledge in visual or direct visual form. As a reflection of this axiom, information and communication technology (ICT) helps to solve the problem of providing students with visualized knowledge. With the help of many programs, browsers and applications that have these technologies, any theoretical knowledge can be visually expressed. The didactic nature of geography provides ample opportunities for the effective use of information and communication technologies in the educational process. The article discusses the didactic possibilities of using information and communication technologies in the teaching of geography.

On modelling the structural quasiness of complex systems

Abstract: Complex systems are usually represented by structurally invariant models acquiring their characteristic properties in simulations. This approach ssumes and infers idealized simplifications to models these systems. We consider this standard approach as omitting crucial features of phenomenological interaction mechanisms related to processes of emergence of such complex systems. We consider, as the main feature, the quasiness of the structural dynamics that generate complex systems. Generation achieved through prevalently coherent sequences and combinations of interactions. Quasiness (dynamics of loss and recovery, inhomogeneity, multiplicity, non-regularity, and partiality) represents the incompleteness of the interaction mechanisms. Complex systems possess local coherences corresponding to the phenomenological complexity. Complex systems are considered quasi-systems, not always systems, not always the same system, and not only systems. We address problems of representing the quasiness of coherence (quasicoherence), such as the ability to recover and tolerate temporary levels of incoherence. The main results of the study focus on modelling quasicoherence through the changing of rules in models of emergence. This is in contrast to models of fixed structural rules allowing only parametrical variations. We present a version of standard analytical approach compatible with quasiness of systemic emergence and related mathematical issues. The same approach is considered for networks, artificial neural networks, and we introduce the concept of quasification for fixed models. Finally, we assert that suitable representations of structural dynamics and its quasiness are needed to model, simulate, and adopt effective interventions on emergence of complex systems. In direct contrast to standard methods that only consider their properties.
