There are diverse factors involved in the transmission of live video over internet. These factors have direct impact on the quality of the transmitted video. The underlying protocol, encapsulation method and the choice of video codec are the, key factors involved in the transmission of video over streaming network. Up to our knowledge various studies have been performed to analyze the impact of these factors individually on the quality of video transmission however their joint impact on video transmission is not yet done. In this paper we characterize the performance of live video streaming setup, while keeping in view the effect of stack-protocol, encapsulation method and the underlying video codec on delay as the key investigating parameter. The results obtained while considering diverse video streaming setups are provided in the results section of this paper. More specifically, it was observed that stack (http, mjpeg, mjpeg) performs best and stack (mms, asf, wmv1) perform worst.

Detecting diseases in jute leaves is difficult due to the variability in how the diseases appear. Manually identifying these diseases is challenging because it requires expert knowledge and visual inspections take a lot of time. Machine Learning (ML) offers a promising solution to these challenges by automating the detection process. However, research in this area is limited due to the lack of specific datasets. This study aims to address this by creating a comprehensive dataset of 10,800 high-quality images of jute leaf diseases. The main goal is to develop a robust system for classifying jute leaves into three categories: Yellow Mosaic, Powdery Mildew, and Healthy. Our methodology involved extensive image preprocessing, including resizing and various augmentation techniques, to enhance the dataset's diversity and ensure model robustness. We trained various ML and Deep Learning (DL) models and conducted a comparative analysis of their performance. Additionally, we compared our approach with the state-of-the-art methods. The results showed that DL models, particularly Inception V3, achieved an outstanding accuracy of 99.98\%, compared to 89.75\% for Random Forest (RF). This highlights the potential of DL techniques in improving the accuracy of jute leaf disease detection. Our findings contribute to better disease management strategies and increased productivity in jute cultivation.

In recent times, Wireless Sensor Networks (WSNs) are broadly utilized in targeted monitoring applications. Traditional target coverage techniques usually consider that environment is known completely and every target is covered by single sensor. However those algorithms are inflexible when the sensor is about to die, that is, lack of energy and therefore target has to be covered with more than a sensor which is termed as n coverage crisis. In general, n coverage problem is energy and time consuming process, as well sensor organization is needed all the time. To resolve this crisis, this work anticipates a n coverage model with VCH-PSO (Virtual Cluster Head based Particle Swarm Optimization and EFLM (Energy management based Fuzzy logic Model) to enlarge the lifetime of WSN. During the search of optimal area coverage, diverse factors like node position, energy consumption, and coverage range of sensors are considered significantly. Simulation was carried out in MATLAB environment and compared with prevailing techniques. The proposed model shows better trade off in terms of network lifetime and time needed for switching between various coverage regions. © 2020 IEEE.

Understanding on-node application power and performance characteristics is critical to the push toward exascale computing. In this paper, we present an analysis of factors that impact both performance and energy usage of OpenMP applications. Using hardware performance counters in the Intel Sandy bridge X86-64 architecture, we measure energy usage and power draw for a variety of OpenMP programs: simple micro-benchmarks, a task parallel benchmark suite, and a hydrodynamics mini-app of a few thousand lines. The evaluation reveals substantial variations in energy usage depending on the algorithm, the compiler, the optimization level, the number of threads, and even the temperature of the chip. Variations of 20% were common and in the extreme were over 2X. In most cases, performance increases and energy usage decreases as more threads are used. However, for programs with sub-linear speedup, minimal energy usage often occurs at a lower thread count than peak performance. Our findings informed the design and implementation of an adaptive run time system that automatically throttles concurrency using data measured on-line from hardware performance counters. Without source code changes or user intervention, the thread scheduler accurately decides when energy can be conserved by limiting the number of active threads. For the target programs, dynamic runtime throttling consistently reduces power and overall energy usage by up to 3%.

A mobile cloud is a cloud infrastructure connecting to mobile devices with a variety of applications (apps). This paper proposes utilizing bigraphical reaction systems (BRSs) to model and analyze a mobile cloud including its contexts such as mobile location, power consumption, network bandwidth, and latency. Simulations and evaluations are performed by matching the reaction rules of BRS with its current agent, on different usage scenarios of mobile cloud, to demonstrate the validity of the proposed methodology.

Business analytics is an important means of gaining new insights and understanding of business performance. Data mining technology provides information needed by business analytics based on data. But due to the barriers of skill, resource and cost, business analytics is hard to carry out and put into practice for small and even medium sized enterprises. This paper presents a novel concept named Highly Consumable Business Analytics (HCBA) aiming to improve consumability of business analytics. We discuss the ways to simplify the use of data mining algorithms, establish end-to-end integrated lifecycle management of model and ultimately wrap models into web service to provide model-wise services. We propose a general reference architecture of HCBA. And a prototype is designed and implemented based on this architecture.

Recent studies indicate that the energy cost and carbon footprint of data centers have become exorbitant. It is a demanding and challenging task to reduce energy consumption in large-scale storage systems in modern data centers. Most energy conservation techniques inevitably have adverse impacts on parallel disk systems. To address the reliability issues of energy-efficient parallel disks, we propose a reliable energy-efficient RAID system called REED, which aims at improving both energy efficiency and reliability of RAID systems by seamlessly integrating HDDs and SSDs. At the heart of REED is a high-performance cache mechanism powered by SSDs, which are serving popular data. Under light workload conditions, REED spins down HDDs into the low-power mode, thereby offering energy conservation. Importantly, during an I/O access turbulence (i.e., I/O load is dynamically and frequently changing), REED is conducive to reducing the number of disk power-state transitions by keeping HDDs in the low-power mode while serving requests with SSDs. We build a model to quantitatively show that REED is capable of improving the reliability of energy-efficient RAIDs. We implement the REED prototype in a real-world RAID-0 system. Our experimental results demonstrate that REED improves the energy-efficiency of conventional RAID-0 by up to 73% while maintaining good reliability.

The conducted electromagnetic interference (EMI) and overvoltage characteristics for a spindle permanent magnet synchronous motor (PMSM) driven by pulse width modulation (PWM) converter are comprehensively presented. The high power, ultra-precision PMSM is applied to a computer numerical control (CNC) grinding machine. The conducted EMI prediction model mainly includes multi-core shielded cable, high frequency (HF) converter and PMSM models. The multi-transmission line (MTL) theory is employed to establish the multi-core shielded cable considering their coupling effect caused by the control pairs. The parasitic capacitance for the PWM converter is calculated by using the analytical formula. The HF equivalent circuit model of the PMSM is obtained combining the methods of impedance measurement and vector fitting method. The influence of the rotor position on the PMSM impedance measurement is considered. The common mode (CM) and differential mode (DM) interference voltage and current both for the output of inverter and the input of PMSM terminals are conducted by using the prediction model. The parametric influence of the long multi-core shielded cables on the overvoltage for the PMSM terminal is discussed.
