Real-Time Vehicles Detection Using a Tello Drone with YOLOv5 Algorithm
No full textIncorporating Unmanned Aerial Vehicles (UAVs) within Artificial Intelligence systems has given rise to an essential and academically significant approach in the domain of vehicle detection. This study introduces a real-time vehicle detection framework leveraging the you only look once (YOLO) algorithm for precise identification of vehicles, employing the camera on the DJI Tello drone. The research is underpinned by a rich dataset encompassing approximately 2000 images, meticulously annotated with the respective vehicle angles. The framework’s innovation lies in its comprehensive training regimen, encompassing all angles of vehicles: Vehicle-front, vehicle-rear, vehicle-above, and vehicle-sides. This holistic approach aims to yield a model capable of accurately identifying and tracking vehicles from a multitude of viewing angles. The choice of the YOLO algorithm, further enhanced by Ultralytics HUB, ensures the robustness and accuracy required for the detection of moving objects. The model’s capability to effectively track objects is a testament to the algorithm’s efficacy. In assessing the framework’s performance, we employed a comprehensive set of evaluation parameters, including mean average precision, precision, recall, and F1 score. This research not only underscores the practicality of UAVs in the field of artificial intelligence but also highlights the excellence achieved in real-time vehicle detection
Multi-Level Feedback Queue Scheduling Technique: Model Proposal to Reduce Risk and Enhance Performance of Healthcare Systems
No full textAbstract - In recent decades, computer technology has been highly developed and applied in numerous aspects of daily life, and the healthcare sector is becoming more aware of the significance of information development. Healthcare systems, including their divisions, can indeed use software applications to minimize risk and enhance performance. This study used the MLFQ technique, assigning a time slot to each queue for MLFQ scheduling so that it changes dynamically with each round of performance. Implementing MLFQS techniques enhances patient satisfaction, minimizes risk, and ultimately delivers high-quality care to patients. It also optimizes patient flow and resource allocation, reducing wait times and delays. The technique divides the ready queue into several queues with different priorities, and each queue has its own scheduling technique. Based on the prioritization, MLFQST reduced the waiting time in the queue over the maximum safety requirements for optimal management by 78 arrivals per 4 hours per day in a week, while the percentage of station time utilization was 22, 19.81, 17.62, and 17.62, respectively. While the average waiting time was 24.56, 29.68, 23.5, and 22.62 minutes, the estimated average support units used by the four stations in the system are Ws = Ls/λ = 1/λ – μ = 0.215 hours = 0.215 * 60 = 12.9 minutes per patient in the waiting queue. The findings indicate a substantial reduction in risk, waiting times in the queue, and enhanced performance.

Determination of Single Sampling Attribute Plans Based Upon Dodge Roaming Model with Application
No full textBayesian sampling plans for production inspection involve using a sampling method to assess the features of the plan, under the assumption that defect rates fluctuate randomly among different production batches. This results in a likelihood distribution that can be established through experience and the quality information at hand. In this study, the parameters of a single Bayesian sampling plan were determined using the Beta-Binomial distribution, and were subsequently contrasted with parameters from other single sampling plans. Based on research findings, (Ala corporation for soft drinks) oversees the control of product quality. Since the variable fluctuates randomly between manufacturing batches, 120 batches were selected to calculate the defect rate by analyzing batch size and number of defective items. Applying Bayesian and decision-making models can lead to the development of a single sampling inspection procedure that closely approximates the actual quality level. When the decision-making model was used, the researchers discovered that the sample size was smaller and led to lower inspection costs compared to other inspection plans
Code Switching by Novice Teachers in EFL Classes and its Effects on Students: Cihan University-Erbil
No full textCode Switching (CS) is shifting from one language to another in a dialogue, a lesson, a sermon, etc. It is used across the board in multilingual communities deliberately and unconsciously. It has many benefits. It has many negative impacts, though. It might distract students’ attention and result in opposite consequences. Therefore, in this study, using CS by novice teachers who do not have enough experience as a medium of explaining the taught material. Besides, it takes into consideration students’ attitudes toward CS as positive or negative. If they understand better after implementing CS, they consider it positive. If, on the contrary, distracts their attention, they consider it negative. The data for this study were collected from 70 students through distributing an open questionnaire and direct observation. They were analyzed using IBM SPSS. The outcomes proposed that some students switch codes at the level of words to have a smooth conversation with colleagues. However, some novice lecturers tend to explain the whole lesson using students’ first language to make sure that they have grasped it well. They do so due to the lack of experience and shortage of vocabulary. The results also pinpointed that some students have a positive reaction toward CS, yet there are many students who do not prefer following it
Reviewing Southern Africa’s Status as a Developmental Region through Governance and Development
No full textThis case study discusses how the democratic governance principles and norms impact development in the SADC, and how institutional and structural reforms require greater participation by society to address the governance challenges encountered in this subregion of Africa. Consequently, the aim of this paper is to examine and assess the relationship between SADC’s governance, democratic principles and norms, development plans and processes. A comparative analysis was conducted using SADC’s key democratic achievement connected to policies, processes, and remaining challenges. Subsequently, the key causes of SADC’s slow development on the African continent were explored, focusing on the failure to institutionalise liberal democratic governance consistently during postcolonial transition periods, speculating SADC’s slow development. The findings suggest that SADC is impacted by democratic principles, norms, and processes, such as local governance, civil society, and decentralisation of power. Bearing in mind Southern Africa’s economic frailty, elevated levels of civil unrest and poor service delivery, SADC authorities require a strong sub-regional governance strategy supported by robust national programmes to determine and overcome the factors hindering the institutionalisation of democratic principles in SADC, and promote strengthened institutional capacity. The unambiguous progression towards the consolidation of democracy, within the SADC, has impacted the governance and development successes of the region, resulting in democratic values and practices remaining shallowly rooted, and slow progress toward open and transparent governance
The 2000–2008 Economic Crisis in Zimbabwe: Status and Survival Strategies of Business Survivors in Rural Areas
No full textBetween 2000 and 2008, Zimbabwe was hit by one of the devastating economic situations which threatened the lives of businesses and also led to the closure of several businesses. The main purpose of this paper was to trace the survivors of Zimbabwe’s 2000-2008 economic distress and establish the strategies they employ to avert future economic pandemics in the country. A mixed research approach was utilised to carry out the study, with data being collected from a sample of 105 business people and their employees in rural Zimbabwe. A self-designed questionnaire and interview guide were used to solicit data from participants with descriptive and thematic analysis data analysis methods being utilised as data analysis tools. The study revealed that while a significant number of businesses closed their businesses due to the economic downturn some survived and self-rejuvenated and moved on in 2009 when the economy stabilised. The strategies most businesses in rural areas employ to avert effects of future economic distress include among others; 1) diversification, 2) trading in foreign currency, 3) avoiding selling goods on credit, and 4) keeping savings in USD and traditional banks. It was recommended that businesses in rural areas need to manage their businesses in a more professional way so that they do not easily get affected by socio-economic shocks and political upheavals
The Role of British Diplomats in Yazidis Affairs in Iraq 1932-1939: An Archival Study
No full textStudying the history of minorities in Iraq has been an important field of interest for many scholars. This study (The Role of British diplomats in Yazidis Affairs in Iraq1932- 1939) is an attempt to present and analyze the role of the British diplomats towards the affairs relating to Yazidi minority in Iraq during a very important period in the latter’s cotemporary history. The Yazidis who had been living in Sinjar a sub-district of Mosul in northern Iraq had been in continuous conflict with Ottoman authorities . This was partly due to their refusal to perform mandatory military service, (compulsory conscription,) and paying taxes. Ottoman campaigns were conducted against them to subjugate them by force to Ottoman rule. This was the reason for their isolating themselves in the mountainous area far from the city center. When British had developed an influence in Iraq an opportunity was presented to the Yazidis to defend themselves. Their leaders asked British authorities to defend their interests and to help them get rid of the oppression of the Ottomans. For the purpose of establishing British influence among the Yazidis , the former called the Yazidi leaders to hold a conference and issue a plea to the British authorities in Iraq to include them under British protection. Britain was planning to set up a Yazidi princedom in Sinjar to serve as a buffer between Iraq and Syria, kipping Frances away from oil field
