Artificial neural networks based multimodal device for autism spectrum disorder.

The neuro developmental condition known as Autism Spectrum Disorder (ASD) affects people on a lifetime basis and exhibits itself in a wide range of ways. In this research work a brand-new semi-supervised training method for the recognition of discrete multi-modal autism spectrum disorder is proposed. At the coarse-grained level, we consider that various methodologies are anticipated to explore equivalent information about child autism. To build DC AlexNet, this combines two small network branches and a large network (trunk network). The network trunk is programmed just to become familiar with the distinguishing characteristics shared by face images at different resolutions. It is built using recently suggested residential components. To project images to a place where their ranges are as little as possible, two branch networks are programmed to learn coupled-mappings (CMs) that are particular to a given resolution. The suggested technique is properly assessed utilizing the databases for the OMEGE and DIAEMO datasets by evaluating it to state-of-the-art techniques in terms of many parameters. Deep Coupled AlexNet is developed to obtain 98.13 % of accuracy, 95.1 % of precision, 94.3 % of recall and 95.4 of F1-score for OMEGE dataset. Moreover, 98.6 % of accuracy, 97.2 % of precision, 98.5 of recall and 97.5 % of F1-score for DIAEMO dataset (Tab. 8, Fig. 10, Ref. 16). Keywords: autism spectrum disorder, artificial neural networks, emotion recognition, interaction design, multimodal factors.

Development and assessment of alternative designs for side impact beam

Side collisions are the second most important cause of death and injury in traffic accidents. Such collisions are riskier than frontal collisions as there are no unique bumpers to absorb the impacts and the space between the passenger and the door is very limited. Therefore, one of the most studied collision types in vehicle safety research is side collisions. Passenger safety is ensured by the A, B, C-Pillar and the side impact beam. This study aims to design and test a composite side door impact beam with a higher strength/weight ratio against impacts. For this purpose, side impact beam design alternatives were created from glass fiber reinforced polymer composite and carbon fiber polymer composite materials, and the samples were tested to obtain maximum force, maximum stress, force/weight ratio, stress/weight ratio, energy absorption ability, specific energy absorption, cost, and mass results. Then, the effectiveness of the designed side impact beams was discussed by comparing the results obtained from the quasi-static compression tests. The study results show that an optimum design can be suggested by evaluating such structural elements in terms of many parameters and establishing trade-off relations between the parameters.

Performance analysis of a new thermal management for thermoelectric cooler

In this paper, a new thermal management method applied to thermoelectric cooler (TEC) is proposed by combining radiative sky cooler (RSC) with air cooling, which can improve cooling capacity and reduce power consumption over a standalone air cooling. The system is based on radiative sky passive cooling and supplemented by air cooling for heat dissipation. A steady-state model is developed to analyze the system performance in terms of many parameters, including the input current, the area of RSC, the cold/hot side temperature, ambient temperature and convective coefficient of air. The results show that the system can significantly increase the cooling capacity and reduce the attenuation of heat dissipation capacity at high ambient temperature compared with a standalone air cooling system. It can achieve complete passive cooling by RSC without any energy consumption when the TEC input power is low. Although increasing the RSC surface area and air cooling intensity can further enhance the cooling capacity, there is a reasonable value between the two, depending on the TEC cold and hot side temperatures. Moreover, it has an optimal input power for different target cooling capacity of TEC, which can minimize the required RSC area.

ПД-14 – чи такий вiн вдалий?

The introductory part of the article provides information about the features of the modern Russian aircraft and engine designations, about the disappearance of the world famous brands such as "Tu", "Yak", "PS", "NK" and others. The tone of many publications testifies to a certain "megalomania" of the Russian aviation industry, whose real achievements of which are greatly exaggerated. One of the main prides of Russia is the PD-14 turbofan engine. This evaluation is the purpose of this article. The history of the development and testing of the PD-14 turbofan engine is given. Simultaneously, it is indicated that it was an alternative engine for the MS-21 aircraft, for which the Western PW-1000G engine was initially selected. Detailed information is given on the production and testing of experimental engines, including in a flying laboratory. It is noted that PD-14 is actually a program for the entire aircraft engine industry in Russia and other enterprises are actively involved in its implementation, in addition to the main subcontractors of the UEC - Aviadvigatel and Perm Motors. In the development of the PD-14, the experience of creating and fine-tuning the PS-90A2 turbofan engine was widely used. It is indicated that when creating the PD-14, many innovative and advanced technologies were developed and applied (16 key technologies). The developers of PD-14 pay considerable attention to the creation of an effective after-sales service system (a network of field offices, engine service stations, spare parts warehouses, ensuring the replacement of modules in operation, etc.), the absence of which previously prevented the successful marketing of Russian engines (a characteristic negative example is the SaM-146 engines of the SSJ regional airliner). General information about the development programs, the main technical characteristics and design features of the competitors of the PD-14 - western PW1000G and LEAP-1 turbofan engines are given. These engines are already widely used in several types of medium-haul aircraft. The PD-14 is compared with its main competitors in terms of many parameters and design characteristics. It is concluded that a modern 5th generation turbofan engine has been created in Russia, which has come close in terms of characteristics and the level of applied technologies to the existing serial Western engines of a similar thrust class. However, the future of the PD-14 engine in the current conditions of the fall of the Russian economy due to the war with Ukraine and EU and US sanctions looks uncertain.

The Study of Associations of ECG Changes in Lead aVR and Lead V6 with Acute Coronary Syndrome (ACS)

BACKGROUND
 The ECG (Electrocardiogram) lead aVR gives reciprocal data for the aVL, II, V5, and V6 leads. It is frequently ignored, even while reviewing complicated ECGs. The purpose of the study was to evaluate the associations of ECG changes in Lead aVR and Lead V6 with acute coronary syndrome (ACS) and coronary complexity as measured by CAG (coronary angiography) in patients with the ACS.
 METHODS
 This was a prospective Hospital-based observational study. A sample size of 80 patients was being used and a study was done on patients admitted to Mahatma Gandhi Medical College & Hospital, Jaipur with ACS, for 18 months, as well as on those who met the inclusion criteria.
 RESULTS
 Of 80 patients enrolled with ACS, the mean age was 60.3500 ± 14.8717 (Mean ± SD). The proportion of patients (72.5 percent) had a history of hypertension, and the prevalence of diabetes in the population was found to be significant. The mean ST elevation in lead aVR of patients was 1.4500 ± 0.6779. The mean ST depression in Lead V6 (Mean ± SD) of patients was 2.1519 ± 0.6063. The mean ST depression in corresponding leads (Mean ± SD) was 2.0375± 0.6303 in patients of ACS. In CAG, 27 (33.8 %) patients had TVD (triple vessel disease), 20 (25.0 %) had DVD (double vessel disease) and 22 (27.5 %) patients had SVD (single-vessel disease). The majority of patients, 46 (57.5 %) had angioplasty, and the distribution of coronary artery bypass graft (CABG) outcomes in the overall population was determined to be significant. ECG changes in leads aVR and V6 correlate with age, lead V1, corresponding leads, troponin levels, and Timi Score (Thrombolysis in Myocardial Infarction). There is a positive association in both leads aVR and V6, and the changes occur concurrently in terms of many parameters, indicating the necessity for additional investigation. The outcomes of our investigation were consistent with the findings of ST-T changes in lead aVR and lead V6.
 CONCLUSIONS
 ECG changes in leads aVR and V6 are associated with poorer prognosis in ACS. Widespread ST-segment depression and ST-segment elevation in lead aVR during episodes of chest pain may represent diffuse subendocardial ischemia caused by severe coronary artery disease (CAD). Further, when interpreting the 12-lead ECG in clinical practice, physicians should give due consideration to the tracing of lead aVR and lead V6 as it can help in identifying the patients who need more aggressive management.

Contribution of Ureteral Access Sheath Use to the Efficacy of Semirigid Ureterorenoscopy in Upper Ureteral Stones Smaller than 2 cm: Experiences of a Single Center

Objective: The aim of our paper is to answer the question that during the ureteroscopy procedure if ureteral access sheath could facilitate operation, could decrease complication rates,operation time,requirement of additional surgery. Method: The patients were randomly divided into two groups. Group 1 contained 44 patients for whom a UAS was not used and Group 2 consisted of 70 patients for whom a UAS was used during the URS procedure. The operation was continued using the semirigid ureteroscope within the UAS. Results: There were no statistically significant differences between the two groups in terms of the mean age, BMI, ASA score, mean stone density, previous unsuccessful interventions, history of stone disease, mean grade of hydronephrosis in renal pelvis and mean stone size. the mean operation time was 41 minutes for Group 1 and 30 minutes for Group 2, with a statistically significant difference (p < 0.001), consistent with the literature. Similarly, the difference in the mean fluoroscopy time was statistically significant, being determined as six minutes for Group 1 and three minutes for Group 2 (p < 0.001). Conclusions: Use of UAS was statistically significantly superior in terms of many parameters, such as increased stone-free rate, shorter operation time, and reduced requirement of additional surgery. Furthermore, the complication rates did not significantly differ between the UAS and non-UAS groups. We also consider that the advantages of a higher stone-free rate and reduced requirement of secondary interventions make the cost of UAS acceptable.

SALDA-ML: Machine Learning Based System Design to Predict Salary In-crease

Number of employees are increases with growing in companies. Firms basically make salary increases for their employees in order not to lose their talents and moreover to increase them. Although there is not much problem in how to in-crease the salary in small organizations, this process should be carried out carefully in terms of many parameters in large organizations and should not result in negativities that may disrupt employee motivation. For companies with a large number of employees, creating a model in which the market conditions are determined correctly and all economic parameters are taken into account reveals the need for a process that needs to be worked on for months. In this context, a machine learning-based salary increase prediction system was designed with the study. Specific attributes were determined and a specific scale was developed for performance score for this study.

Edirne İli Barajlarının Bazı Fiziko-Kimyasal Özellikleri ve Sulama Suyu Kalite Sınıfları

Water pollution which is the daily problem of the whole world has increased in parallel with industrialization, urbanization and population, and it is increasing rapidly. At the same time, intensive and uncontrolled water consumption causes the decline of underground and over ground water resources day by day in Thrace Region. Having information about the quality of the water used in the irrigation is a significant indicator in order to prevent the problems in the soil. In this study, 4 dams in Edirne province were handled and convenience of the dams in terms of irrigation water was determined. According to the results, Suloglu dam was in T1A1 and T2A1 irrigation water class. Altinyazi dam, Sultankoy dam and Hamzadere dam were in T3A1 irrigation water class. When the quality criteria of the dams were examined according to the intra-continental ground water sources classes, it was determined that Suloglu dam, Sultankoy dam and Hamzadere dam were in II and III classes and Altinyazi dam was in the II class. According to FAO-29 classification, Suloglu, Sultankoy and Altinyazi dams were generally in I the class and Hamzadere dam was in the II class in terms of many parameters.

Parametric Models of the Product Novelty Assessment Through the Basic Structures Approach

The Achievement of essential consumer parameter values or the implementation of new functionality determines the degree of novelty of the product. However, issues related to the evaluation of technical and scientific novelty of experimental products remain open. This is due to different approaches in the formulation of the problem in terms of many parameters. One of the known approaches to quality assessment is the formation of options based on the basic structures. This approach is consistent with the practice of creating a new product based on a retrospective analysis of the basic structures in the selected problem area. Known, for example, models of functionally necessary and functionally sufficient structures, basic structures represented by the point of the multidimensional parameter space. An important complement to this approach is to take into account the constraints required to manage the quality of an innovation project. The process of improving the parameters of new products is halted by the existing limitations, both in scientific and technological progress and in the social environment. The paper proposes to determine the degree of change in the technical characteristics of new products in relation to the current analogue or adopted prototype. The set of technical and social requirements established for the product by the terms of technical requirements and normative documents determine the functional significance of new products. Models and methods of estimation of a product novelty achievability in the conditions of not completely clear requirements of the market are offered. The analysis of the degree of change of parameter values is performed using fuzzy logic and flexible calculations. The parametric model application allows, taking into account the existing limitations, to determine the required level of perspective novelty of products.

Comparison of radiofrequency and transoral robotic surgery in obstructive sleep apnea syndrome treatment

Introduction: Radiofrequency tissue ablation (RFTA) and transoral robotic surgery (TORS) are the methods used in OSAS surgery. We also aimed to compare the advantages and disadvantages of RF and TORS as treatment methods applied in OSAS patients in terms of many parameters, especially apnea hypopnea index (AHI).Materials and methods: Patients were classified by performing a detailed examination and evaluation before surgery. 20 patients treated with anterior palatoplasty and uvulectomy −/+ tonsillectomy + RFTA (17 males, 3 females) and 20 patients treated with anterior palatoplasty and uvulectomy −/+ tonsillectomy + TORS (16 males, 4 females) were included in the study. PSG was performed preoperatively and postoperatively in all patients and Epworth sleepiness questionnaire was applied. All operations were performed by the same surgeon and these surgical methods -RF and TORS- were compared in terms of many parameters.Results: When the patients treated with RF and TORS were compared in operation time, length of hospitalization and duration of transition to oral feeding; all parameters were significantly greater in the patients treated with TORS.Conclusions: TORS technique was found to be more successful than RF in terms of reduction of AHI value, correcting minimum arterial oxygen saturation value and decreasing Epworth Sleepiness Scale score.

A comparative study of outcomes of Lichtenstein repair and Desarda tissue repair in patients of inguinal hernia

Background: Inguinal hernia is a very common surgical problem for which, mesh-based techniques, particularly the Lichtenstein repair is considered standard. However, problems like foreign body sensation, wound infection, cord fibrosis, chronic pain and recurrence are major concern. Desarda tissue repair (non-mesh technique), which was given by an Indian surgeon, is now being used in many countries because of low cost of procedure with very low recurrence rates. The objective of this study was to evaluate the feasibility of Desarda tissue repair at a tertiary care centre of Central India as a treatment of primary inguinal hernia, by comparing it with Lichtenstein repair in terms of various post-operative parameters.Methods: Patients between age of 18 and 70 years with primary inguinal hernia were included in this randomised controlled trial. Patients with strangulated, obstructed or recurrent hernia, surgically unfit patients and patients having unmanaged urinary obstruction, cough or constipation were excluded. Randomization was done by sealed envelope method into Lichtenstein and Desarda arm and respective surgeries were performed.Results: 90 patients were included in the study and average duration of follow-up was 15.1 months. Operative time was significantly less in Desarda arm (14.75 min compared to 21.32 min in Lichtenstein arm). Cost, incidence of seroma formation, post-operative pain, foreign body sensation and chronic pain were also significantly less in Desarda arm. No recurrence was observed in both arms.Conclusions: Desarda repair is easy to perform and takes less time to perform and proves cost effective. Desarda repair is comparable to Lichtenstein repair in terms of many parameters and superior in terms of post-operative pain and foreign body sensation and can be preferred for young patients. In infected and strangulated cases, Desarda repair can be used effectively without fear of mesh infection.

Performance Improvement of Cluster-Based Routing Protocol in VANET

Vehicular ad-hoc NETworks (VANETs) have received considerable attention in recent years, due to its unique characteristics, which are different from mobile ad-hoc NETworks, such as rapid topology change, frequent link failure, and high vehicle mobility. The main drawback of VANETs network is the network instability, which yields to reduce the network efficiency. In this paper, we propose three algorithms: cluster-based life-time routing (CBLTR) protocol, Intersection dynamic VANET routing (IDVR) protocol, and control overhead reduction algorithm (CORA). The CBLTR protocol aims to increase the route stability and average throughput in a bidirectional segment scenario. The cluster heads (CHs) are selected based on maximum lifetime among all vehicles that are located within each cluster. The IDVR protocol aims to increase the route stability and average throughput, and to reduce end-to-end delay in a grid topology. The elected intersection CH receives a set of candidate shortest routes (SCSR) closed to the desired destination from the software defined network. The IDVR protocol selects the optimal route based on its current location, destination location, and the maximum of the minimum average throughput of SCSR. Finally, the CORA algorithm aims to reduce the control overhead messages in the clusters by developing a new mechanism to calculate the optimal numbers of the control overhead messages between the cluster members and the CH. We used SUMO traffic generator simulators and MATLAB to evaluate the performance of our proposed protocols. These protocols significantly outperform many protocols mentioned in the literature, in terms of many parameters.

Malinovka deposit—A new type of gold mineralization in Primorye, Russia: Geology, mineralogy, and genesis

Original data on the ore composition are obtained by studying samples from mining workings. In terms of mineral composition, gold-productive veinlets are subdivided into three types: sulfide–quartz, sulfide–carbonate–quartz, and sulfide. The wall-rock metasomatites and typomorphic features of the minerals are studied and the genetic problems of the ores and deposit are discussed. It is established that the Malinovka deposit is ascribed to the gold–tourmaline type (gold–quartz formation), which is identified for the first time in Primorye. In terms of many parameters, the ores of this type are close to those of the large deposits from the Transbaikalian and Amur regions (Klyuchevsky, Kariy, Kirov, Darasun, and others), which are genetically related to granitoid magmatism.

Assessment of the turkey’s electric power policies in terms of sustainability

This study, using statistical data published by the Turkish Electricity Transmission Company, analyzes key parameters such as installed capacity and energy demand growth rates, investment plans and emission rates, taking into consideration the expected increase in use through the year 2023. The results of the analyses were compared to relevant data from around the world. The weight of domestic - and especially renewable - resources in investment plans for the next 10 years was discussed. Recommendations for an investment plan to support sustainable development in Turkey are listed. Consequently, the lack of investment in domestic and renewable energy projects decreases the competitive power of Turkey vis-?-vis Organisation for Economic Co-Operation and Development countries in terms of many parameters. For a sustainable development, the country must make significant changes in its foreign-dependent energy production policies. Any future policies must encourage supplying local resources to meet the continuously increasing demand. Qualifications for incentive mechanisms applied to investments in renewable energy should be developed. The impact of the private sector on the installation of new plants must also be increased by quickly completing the privatization process.

Assessment of the State of Flounders from Sivuch'ya Bight (Peter the Great Bay, Sea of Japan) Based on Histopathological Parameters

The liver and gills of five flounder species (Pleuronectes obscurus, P. punctatissimus, P. yokahamae, P. herzensteini, and Platichthys stellatus) from Sivuch'ya Bight were histologically studied. Specimens of all species were characterized by a wide spectrum of histomorphological changes. The proportions of most specific pathologies in P. obscurusfrom Sivuch'ya Bight were estimated. The pathologies comprised two major groups: those of the gills (edema and fusion of the respiratory lamellae; lifting and hyperplasia of the respiratory epithelium; vacuolization of the epithelium cells; and the presence of clavate lamellae, aneurysmal areas, and parasites) and those of the liver (vacuolization of the hepatocytes, aneurysms, necrosis of the parenchyma tissue, pathologies of the hepatocyte nuclei, pigment accumulation, and an increase in the number and size of melanomacrophage centers). The estimated proportions of pathological changes were compared with those observed in P. obscurusspecimens from the most contaminated area of Amurskii Bay. In both Sivuch'ya Bight and Amurskii Bay, the proportion of fish with various pathologies was high. The comparison of pathological changes in the gills and liver of P. obscurusand P. stellatusfrom Sivuch'ya Bight showed that, in terms of many parameters, the former species is more sensitive to pollution of the marine environment than the latter. Pathomorphological changes in the organs of the flounders studied are apparently caused by chronic pollutant action and suggest that the fish of both areas are in a damaged state.

Mathematical Relationship Predicting Grain Separation in Combines

ABSTRACT TO achieve the proper design of a combine straw walker that can efficiently separate the grain from the plant material, the physical process of this separation must be understood. An equation, which describes the physical separation of the grain from the plant material was derived in terms of many parameters typically omitted by researchers. The derived equation included the parameters width of separation, material flow rate, bulk density of the material, thickness of the separation layer, and a diffusion coefficient. Using published data, the model was evaluated in terms of material flow rate and straw walker length. The R^ values for length for all data sets were greater than 0.99, and significant at the 99.9% level (a = 0.001). In addition to the initial derivation, variables in the separation function were related to the rate of material flow and the type of plant material. The flow rate relationship also gave a high R^ (0.90) and was significant at the 95% level (a = 0.05). It was also shown that grain size and straw type has an effect on rate of separation.
