A Study Resource Optimization Techniques Based Job Scheduling in Cloud Computing
Cloud computing has revolutionized the way businesses and individuals utilize computing resources. It offers on-demand access to a vast pool of virtualized resources, such as processing power, storage, and networking, through the Internet. One of the key challenges in cloud computing is efficiently scheduling jobs to maximize resource utilization and minimize costs. Job scheduling in cloud computing involves allocating tasks or jobs to available resources in an optimal manner. The objective is to minimize job completion time, maximize resource utilization, and meet various performance metrics such as response time, throughput, and energy consumption. Resource optimization techniques play a crucial role in achieving these objectives. Resource optimization techniques aim to efficiently allocate resources to jobs, taking into account factors like resource availability, job priorities, and constraints. These techniques utilize various algorithms and optimization approaches to make intelligent decisions about resource allocation. Research on resource optimization techniques for job scheduling in cloud computing is of significant importance due to the following reasons: Efficient Resource Utilization: Cloud computing environments consist of a large number of resources that need to be utilized effectively to maximize cost savings and overall system performance. By optimizing job scheduling, researchers can develop algorithms and techniques that ensure efficient utilization of resources, leading to improved productivity and reduced costs. Performance Improvement: Job scheduling plays a crucial role in meeting performance metrics such as response time, throughput, and reliability. By designing intelligent scheduling algorithms, researchers can improve the overall system performance, leading to better user experience and customer satisfaction. Scalability: Cloud computing environments are highly scalable, allowing users to dynamically scale resources based on their needs. Effective job scheduling techniques enable efficient resource allocation and scaling, ensuring that the system can handle varying workloads without compromising performance. Energy Efficiency: Cloud data centres consume significant amounts of energy, and optimizing resource allocation can contribute to energy conservation. By scheduling jobs intelligently, researchers can reduce energy consumption, leading to environmental benefits and cost savings for cloud service providers. Quality of Service (QoS): Cloud computing service providers often have service-level agreements (SLAs) that define the QoS requirements expected by users. Resource optimization techniques for job scheduling can help meet these SLAs by ensuring that jobs are allocated resources in a timely manner, meeting performance guarantees, and maintaining high service availability. Here in this research, we have used the method of the weighted product model (WPM). For the topic of Resource Optimization Techniques Based Job Scheduling in Cloud Computing For calculating the values of alternative and evaluation parameters. A variation of the WSM called the weighted product method (WPM) has been proposed to address some of the weaknesses of The WSM that came before it. The main distinction is that the multiplication is being used in place of additional. The terms "scoring methods" are frequently used to describe WSM and WPM Execution time on Virtual machine, Transmission time (delay)on Virtual machine, Processing cost of a task on virtual machine resource optimization techniques based on job scheduling play a crucial role in maximizing the efficiency and performance of cloud computing systems. By effectively managing and allocating resources, these techniques help minimize costs, reduce energy consumption, and improve overall system throughput. One of the key findings is that intelligent job scheduling algorithms, such as genetic algorithms, ant colony optimization

The impact of modern headlamps on the design of sag vertical curves
Incorporating safety in the design of a highway is one of the foremost duties of a design
engineer. Design guidelines provide standards that help engineers include safety in the
design of various geometric features. However, design guidelines are not frequently
revised and do not accommodate for the frequent changes in vehicle design. One such
example is the change in vehicle headlamps. These changes significantly impact the
illuminance provided on the road and in turn the design formula.
Roadway visibility is critical for nighttime driving. In the absence of roadway
lighting, vehicle headlamps illuminate the road ahead of a vehicle. Sag vertical curve
design depends on the available headlight sight distance provided by the 1 degree
upward diverging headlamp beam. The sag curve design formulas were developed in
the early 1940s when sealed beam headlamps were predominant. However, headlamps
have changed significantly and modern headlamps project less light above the horizontal
axis. In this research, the difference in illuminance provided by sealed beam headlamps
and modern headlamps was examined. For the theoretical analysis, three different sag
curves were analyzed. On these curves, about 26 percent reduction in illuminance was observed at a distance equal to the stopping sight distance when comparing sealed beam
to modern headlamps. A change in the headlamp divergence angle from 1.0 degree to
0.85 degree will provide the required illuminance on the road when using modern
headlamps. A field study was performed to validate the theoretical calculations. It was
observed that for modern headlamps, a divergence angle less than 1 degree and greater
than 0.5 degrees will provide illuminance values comparable to sealed beam headlamps.
As a part of this research, a preliminary study, examining the impact of degraded
headlamp lenses on the illuminance provided on sag vertical curves was conducted. A
significant reduction in illuminance reaching the roadway on sag curves was observed,
due to headlamp lens degradation

Role of Multidetector Computed Tomography in the Assessment of Olfactory Fossa Depth among the South Indian Population: A Cross-sectional Study
Introduction: Functional Endoscopic Sinus Surgery (FESS) is one of the most commonly performed surgeries for sinusitis. The olfactory fossa is prone to injury during FESS and the risk of injury depends on the depth of the olfactory fossa.
Aim: To assess the depth of the olfactory fossa by multidetector Computed Tomography (CT) and to study the incidence and distribution of asymmetry of olfactory fossa depth.
Materials and Methods: A cross-sectional, observational study was conducted at Department of Radiology, Dr Pinnamaneni Siddhartha Institute of Medical Sciences and Research Foundation, Gannavaram, Andhra Pradesh, India from November 2019 to October 2019. The sample size was 500 patients. All patients above the age of 18 years who were referred to the department of radiology for CT paranasal sinuses were included. Olfactory fossa depth was calculated from the CT scan and statistical analysis was done comparing it with the variables such as age, gender and side of fossa.
Results: Out of total 500 participants, 311 (74.2%) patients in the study were males. The mean age of patients was 40.3±16.05 years. There was no significant difference in the olfactory fossa depth on the right side (p-value=0.6) and left side (p-value=0.9) in both genders. A total of 400 (80%) patients of the cases had asymmetry of the olfactory fossa. In males, the most common (n=294, 799.2%) was type 2 Keros on the right and 280 (75.5%) patients on the left side. In females on the right side, type 1 Keros was more common (52 patients, 40.3%) and on the left side type 2 Keros was more common (60 patients, 46.5%) and there was a significant difference in the proportion of different types of Keros in both genders (p-value<0.001). There was no significant difference in the proportion of Keros types among the different age groups (p-value=0.56 on the right side and p-value=0.66 on left side).
Conclusion: There was a significant difference in the proportion of Keros types among males and females and the majority of the patients had asymmetry. Prospective studies with intraoperative information from the surgeon can add further information on the utility of the Keros grade
