Bi-Level Optimization Model for Urban Traffic Control
Authors: Stoilova Krasimira , Stoilov Todor , Dimitrov Stanislav 
Published: December 2021

Abstract
The urban traffic control optimization is a complex problem because of the interconnections among the junctions and the dynamical behavior of the traffic flows. Optimization with one control variable in the literature is presented. In this research optimization model consisting of two control variables is developed. Hierarchical bi-level methodology is proposed for realization of integrated optimal control. The urban traffic management is implemented by simultaneously control of traffic light cycles and green light durations of the traffic lights of urban network of crossroads.
Simulation-Based Optimisation for Autonomous Transportation Systems Using a Parallel Real-Coded Genetic Algorithm with Scalable Nonuniform Mutation
Authors: Akopov Andranik S. , Beklaryan Levon A. , Beklaryan Armen L. 
Published: December 2021

AbstractThis work presents a novel approach to the simulation-based optimisation for Autonomous Transportation Systems (ATS) with the use of the proposed parallel genetic algorithm. The system being developed uses GPUs for the implementation of a massive agent-based model of Autonomous Vehicle (AV) behaviour in an Artificial Multi-Connected Road Network (AMСRN) consisting of the “Manhattan Grid” and the “Circular Motion Area” that are crossed. A new parallel Real-Coded Genetic Algorithm with a Scalable Nonuniform Mutation (RCGA-SNUM) is developed. The proposed algorithm (RCGA-SNUM) has been examined with the use of known test instances and compared with parallel RCGAs used with other mutation operators (e.g., standard mutation, Power Mutation (PM), mutation with Dynamic Rates (DMR), Scalable Uniform Mutation (SUM), etc.). As a result, RCGA-SNUM demonstrates superiority in solving large-scale optimisation problems when decision variables have wide feasible ranges and multiple local extrema are observed. Following this, RCGA-SNUM is applied to minimising the number of potential traffic accidents in the AMСRN.

Published: December 2021

Abstract
This paper presents the identification of the ThermoElectric Cooler (TEC) plant using a hybrid method of Multi-Verse Optimizer with Sine Cosine Algorithm (hMVOSCA) based on continuous-time Hammerstein model. These modifications are mainly for escaping from local minima and for making the balance between exploration and exploitation. In the Hammerstein model identification a continuous-time linear system is used and the hMVOSCA based method is used to tune the coefficients of both the Hammerstein model subsystems (linear and nonlinear) such that the error between the estimated output and the actual output is reduced. The efficiency of the proposed method is evaluated based on the convergence curve, parameter estimation error, bode plot, function plot, and Wilcoxon’s rank test. The experimental findings show that the hMVOSCA can produce a Hammerstein system that generates an estimated output like the actual TEC output. Moreover, the identified outputs also show that the hMVOSCA outperforms other popular metaheuristic algorithms.
Non-Indigenous Parasites of Fish in Inland Waters of Croatia
Authors: Pofuk Matija 
Published: December 2021

AbstractNon-indigenous parasite fauna of freshwater fish has not been studied extensively in Croatia, despite the long history of introductions and translocations of alien fish species into inland waters. Negative implications for aquaculture production and wild native fish species have been frequently associated with the introduction of non-native parasite species. Hence, the present paper attempts to lay out a historical overview of the suspected localities, time frames and pathways of introduction for non-indigenous fish parasites into inland waters of Croatia, therefore producing a list of species. In total, 16 non-native fish parasites have been recorded in inland waters of Croatia, aquaculture establishments being identified as initial points of introduction. However, a paucity of information exists on the overall prevalence of infection as well as the economic impact on aquaculture production. In addition, limited information is available about the presence and potential ecological impact of non-indigenous parasites on endemic fish fauna in areas of high biodiversity, such as the water bodies of the Adriatic Sea Basin. Therefore, there is an urgent need and opportunity for multidisciplinary cooperation between different stakeholders, including government, scientists, in both biological and veterinary disciplines, and the industry, with the aim of extensive surveys to determine the potential impact on aquaculture production and wild fish population of high conservation value.

Published: December 2021

Abstract

Objectives. Given the high prevalence of subclinical hypothyroidism (SCH), defined as high thyroid stimulating hormone (TSH) and normal free thyroxine (FT4), and uncertainty on treatment, one of the major challenges in clinical practice is whether to initiate the treatment for SCH or to keep the patients under surveillance. There is no published study that has identified predictors of short-term changes in thyroid status amongst patients with mild elevation of TSH (4.5–10 mIU/L).

Subjects and Results. A cohort study was conducted on patients with SCH detected through a general population screening program, who were followed for six months. This project identified factors predicting progression to hypothyroid status, persistent SCH and transient cases. A total of 656 participants joined the study (431 controls and 225 were patients with SCH). A part of participants (12.2%) developed biochemical hypothyroidism during the follow-up, while 73.8% of the subjects became euthyroid and the remained ones (13.4%) stayed in the SCH status. The incidence of overt hypothyroidism for participants with TSH above 6.9 mIU/L was 36.7%, with incidence of 42.3% for females. Anti-thyroid peroxidase antibodies (TPO) positivity is an important predictor of development of hypothyroidism; however, it could be also positive due to transient thyroiditis.

Conclusions. It can be concluded that females with TSH above 6.9 mIU/L, particularly those with free triiodothyronine (FT3) and FT4 in the lower half of the reference range, are more likely to develop biochemical hypothyroidism. Therefore, it is recommended to give them a trial of levothyroxine replacement. It is also recommended to repeat TSH after six months for male subjects and participants with baseline TSH equal or less than 6.9 mIU/L.
The increase in urinary serotonin and decrease in salivary cortisol concentrations following direct inhalations of concentrated essential oils is not induced by non-specific effects
Authors: Schneider Rainer 
Published: December 2021

Abstract

Objectives. The effectiveness of exogenously triggered serotonin (e.g., dietary supplements, drugs) increase is varied. However, since urinary serotonin concentrations were found to correlate with those in the cerebrospinal fluid, the olfactory system might be an efficient and testable pathway to quickly elevate serotonin levels due to its fast-acting central neurophysiological and peripheral pathways. However, little research has been devoted to investigate this assumption. This paper extends previous findings of parasympathetic activation of a specially designed essential oil inhaler (AromaStick® Balance) by experimentally testing its impact on urine serotonin and saliva cortisol excretion.

Method. Two experiments involving healthy individuals were conducted to test the efficacy of essential oil application to the nose by employing different inhalation protocols and control conditions.

Results. In the pilot study (n=8), serotonin urine excretion was increased after six inhalations (effect size Cohen’s d=0.7). In the second experiment (n=80), inhalations proved superior to both the natural control condition and the pseudo placebo condition after three and six inhalation cycles (0.6<d<1.8). In addition, there was a large reduction of cortisol saliva levels after three inhalations (d=0.9).

Conclusion. Short and deep inhalations of essential oil scents directly delivered to the olfac-tory system appear to result in an enhanced serotonin and a reduced cortisol release in healthy individuals of both sexes.
Interaction Between the Transport Network and the Territory of Algiers (Complex System): In Search of Indicators
Authors: Baba Slimane Nour El Houda , Baouni Tahar 
Published: December 2021

Abstract
In recent years and within the framework of its project “Algiers the metropolis”, Algiers has classified its transport network among its first concerns in order to compete with the other Mediterranean metropolises. However, the complexity of its territory, which is of a particular geological and geomorphological nature, represents a constraint for the proper distribution and management of its transport network. The complexity of its territory and of its transport network, leads us towards the systemic approach for the search of an adequacy between these two complex urban realities in order to find an effective and efficient tool of management and urban planning. The development of a set of indicators of sustainable mobility, as a result of this work, allowed us to find through an epistemological study of the literature on the two complex concepts to select and develop a list of Input and Output Indicators that are related to both territory and transport. Indeed, this list of sustainable mobility indicators will allow, on the one hand, in urban planning, a better match of the transport network to the Algerian territory and, on the other hand, the study of the effectiveness and efficiency of the present and future transport network.

Published: December 2021

Abstract
The characteristics of the industrial heritage (antiquity, architectural, cultural, technological value) determined its inscription in the category of historical monuments. In recent years, non-invasive digital technologies have been used in studies focused on documenting, digitizing, preserving elements of industrial heritage. Also, another objective of digitizing the industrial heritage is to facilitate its promotion as a cultural resource among the general public. The purpose of this study is to promote the railway station of Curtea de Argeş through non-invasive technology. The analyzed industrial monument represents a symbolic building of the neo-Romanian architectural style. The building is also associated with a remarkable historical value: the railway station was also used by the Romanian royal family. Based on the use of terrestrial photogrammetry (versatile GNSS RTK GS18 I sensor) and aerial (photogrammetric flight), the authors created the 3D model of the station, obtaining a high-resolution modeling. The results of this study reflect the usefulness of modern technology for documenting, 3D modeling and promoting an industrial monument inscribed on the list of national cultural heritage. The accuracy and optimal performance of the measurements made, using GNSS technology and aerial photogrammetry, allowed highlighting the remarkable architectural and volumetric characteristics of the railway station of Curtea de Argeş Municipality.

Abstract
In construction industry, demolished construction waste is recently used as reprocessed aggregate to produce environmentally friendly concrete which is a good substitute to normal crush due to increased demand of ecological growth and conservation benefits. Though, the properties of recycled aggregate concrete are smallest as compared to concrete produced from natural aggregate and these properties can be enhanced by adding some materials having cementitious properties. Rice husk ash (RHA) is used as partial replacement of cement in recycled aggregate concrete to improve the properties as well as to conserve the natural resources. The elementary purpose of this investigation is to determine the compressive strength of concrete by the replacement of cement with different percentages of rice husk ash such as 0%, 7.5%, 10%, 12.5%, 15%, and 17.5% respectively with different curing conditions. For the experimental program approximate 198 cylinders (18 for rapid curing, 90 for normal water curing and 90 for acid curing) are casted with the mix proportion of 1:2:4 and water to cement ratio of 0.50 whereas curing is done at the ages of 3,7,14,21 and 28 days. Various experiments are performed on fresh and hardened concrete to determine the effects of rice husk ash on recycled aggregate concrete with different curing conditions. Linear regression analysis is carried out to determine the compressive strength of concrete. It is pragmatic from the slump test results that the workability of recycled aggregate concrete is decreased by increasing the quantity of rice husk ash. This reduction in slump is due to high water absorption of recycled aggregates and rice husk ash. Further, the compressive strength of recycled aggregate concrete with normal and acid curing is decreased by increasing the percentages of rice husk ash. It is also observed that at 28- days of normal water curing for mix M1,M2,M3,M4,M5 and M6 the compressive strength is increased by 0.96%, 2.74% 1.45%,4.50%,4.23% and 4.22% respectively as compared to the compressive strength values at 28 days of acid water curing. Therefore, it is concluded that recycled aggregate concrete with 10 to 12% of rice husk ash is suitable for properties of concrete. The acid water curing has negative impacts on hardened properties of concrete as it reduced the compressive strength of concrete as compared to normal water curing.

Abstract
In the science of seismology, issues such as the study of tectonic seismic maps and the identification of the behavioural pattern of pre-earthquakes and aftershocks are among the cases that have been proposed as the basis of applied geological studies in recent decades. Accordingly, numerous studies and researches in this field have been carried out in different regions of the world. However, the results of these studies so far have not been able to meet the needs of this field in a practical and practical way, and in this regard, there is a need to provide practical approaches in this field. In order to realize this approach, there is a need for specialized research and case studies in this field in order to be able to present studies on earthquake risk reduction in an institutionalized and practical way by identifying practical patterns. In this study, the basis of the case study, considering the special characteristics of Tasuj earthquake as one of the important earthquakes according to the basic patterns that can be provided in this field for this earthquake has been considered. Also geodetic analysis of Tasuj fault and the other faults studied for estimation of accuracy this analysis for prediction of earthquake. The results of this study indicate that the fault causing the Tasuj earthquake, contrary to what is presented in the fault map of the region and previous reports and articles, is of the strike-slip type, which should be corrected. Also, the analysis of the behavioural pattern of geodetic data, foreshocks and aftershocks as a precursor shows that these patterns can be used in predicting major earthquakes and large aftershocks. To predict the time of large aftershocks in this study, three phases have been used, which are based on changes in depth to magnitude, changes in seismic quiescence to magnitude and depth changes.
