SWOT analysis of Halfeti's rural tourism potential in the context of rural development

2024-04-30T13:14:46-03:00

Halfeti district, located in the southeast of Turkey, is a destination area with tourism potential with its natural beauties, ruins reflecting historical, religious and cultural heritage, and endemic plant and animal existence. With the Birecik dam starting to collect water, the flooded rural settlement areas have become interesting and the tourism destination value of Halfeti district has further increased. Halfeti's tourism value continues to increase day by day after it was included in the Cittaslow network in 2013. Local community, who earned income only through animal and plant production in the past, have gone into rural tourism activities with these changes in Halfeti district, and Halfeti has taken a special place among rural tourism destination areas today. In this study, the rural tourism potential of Halfeti district was investigated in the context of rural development. In the study, SWOT analysis was conducted using primary data. As a result of the SWOT analysis, it was determined that the strengths of Halfeti district in terms of rural tourism potential are greater than its weaknesses. In addition, suggestions are offered for using Halfeti's rural tourism potential in ensuring rural development.

2024-04-30T13:14:45-03:00

This article analyzes different architectures with which a neural network can be developed using computer vision with the objective of detecting traffic accidents. For the development of the software, the Java Script programming language was used, reaching the conclusion that the best architecture to use is a Convolutional Neural Network since it has the capabilities of detecting features within the images. At the same time, a database was developed with the necessary characteristics for the functioning of the neural network.

Characterization of a low power wind turbine prototype for interconnection to the grid

2024-04-30T13:14:45-03:00

In this article, a prototype of a low power wind turbine interconnected to the NETWORK and the controlled electronic converter for the rectification of the generated voltage was designed, which is used for the conditioning of the electrical power generated by low power wind systems for the Connection to the electric grid. Using different electronic components and free hardware development boards, the construction of a controlled three-phase rectifier prototype was carried out, divided into 3 modules, the first one in charge of obtaining a reference signal and synchronization of the voltage to be rectified, the second is the control circuit, which performs the time calculations for the activation of the third module, in charge of rectifying the triphasic voltage using thyristors (SCR), in which the moment of activation of the semiconductors can be controlled. Finally, tests of the prototype connected to a wind turbine built by teachers and students of the Technological University of Campeche were carried out, verifying its correct operation in the rectification of the voltage delivered by this generator.

Estimation of refractivity gradients and effective earth radius factor (K-factor) in the lowest 100 m of the atmosphere over Ogbomoso, southwestern Nigeria

Upon deviation from standard condition, anomalous propagations are usually experienced in within the atmosphere. As a result, it is very pertinent to considered the value of the tropospheric refractive index while planning, designing and implementing microwave systems. In this study, measurements of meteorological parameters (temperature, relative humidity, and atmospheric pressure) were conducted for a period of 12 months (Jan - Dec, 2021) in Ogbomoso (8.17ºN, 4.24ºE, 372 m above sea level) using a collection of wireless Davis Vantage Pro2 6162 automatic weather stations. The hourly time series of these measured data were extracted and converted to monthly averages and used to compute refractivity, gradient of refractivity, and the k-factor. From the Analyses, results revealed a generally high values of refractivity during the rainy months with a peak value of 359 recorded in May. The values were observed to decrease with increasing height. For the period of this observation, the mean refractivity gradient was found to be 50 N-units/km while the average value of K-factor was 1.49. As a result, it was concluded from these findings that the propagation condition in Ogbomoso is super-refraction.

Optimal tuning of PID controller parameters for AGC of a wind

2024-04-30T13:14:45-03:00

The interconnected power systems response control has become more challenging with the integration of wind energy due to the variable range of wind speed and power output. In addition to load perturbations, fluctuations in wind power can also impact system frequency. Therefore, enhancing current control strategies is essential to maintain the stability of the frequency in these complex power system scenarios. The Controller is tuned in three methods. The new tuning methods are introduced to the conventional proportional-integral and derivative controller such that the system gives best performance. These tuning methods are Genetic Algorithm (GA) and Harmony Search Algorithm (HSA) used to study the system performance in comparison between them on Time Domain Analysis. The system is also tested for its robustness in three cases as the nominal loads for both the areas and with the load disturbance and the controller by its gain variations. The system's results are acquired through the utilization of the MATLAB/Simulink software.

Progress in the welding of AL alloy thin sheet and future prospectus for automobile

2024-04-30T13:14:46-03:00

Since the early 21st century, the automotive and aluminium industries have rapidly developed a variety of advancements in response to competitive, environmental, and technological problems. Reduction in tare weight of vehicle is one approach for dealing with some of these problems. Al alloys have potential to save mass, which is need for fuel efficiency, environment pollution and emerging electrical vehicle. The estimated consumption of Al alloy in vehicle by 2025 is 250 Kg from current 180 Kg. However, the difficulties in welding Al alloy have hindrance their widespread adoption. Al alloys, which are regarded as being challenging to fuse using a traditional process because of its intrinsic qualities, such as its low melting point, high thermal conductivity, high solubility in hydrogen, formation of oxides, and significant solidification shrinkage. Currently low heat input welding process such as MIGW, TIGW, FSW, LBW and EBW are employed by industries for thin sheet Al alloy. However, each of these techniques’ variants suffers from few limitations. Therefore, joining of Al alloy thin sheet is still a difficult and costlier task. Weld beads frequently exhibit many defects which significantly lower the mechanical and fatigue strength of thin Al alloy sheets. This overview aims to provide a concise summary of current advancements in the joining of Al alloys and shows the future prospectus and direction of development in joining of thin sheet Al alloy. The researchers working on joining Al alloys are also intended beneficiaries of this study.
