Earned value management (EVM) is a well-known approach in a project control system which uses some indices to track schedule and cost performance of a project. In this paper, a new statistical framework based on self-starting monitoring and change point estimation is proposed to monitor correlated EVM indices which are usually auto-correlated over time and non-normally distributed. Also, a new ...

The high demand for multimedia applications in environmental monitoring, invasion detection, and disaster aid has led to the rise of wireless sensor network (WSN). With the increase of reliability and diversity of information streams, the higher requirements on throughput and quality of service (QoS) have been put forward in data transmission between two sensor nodes. However, lower spectral ef...

This paper discusses practical constraints of Error Vector Magnitude (EVM) measurements for high-coverage Radio Frequency Integrated Circuit (RFIC) device testing. Noise, distortion, spurious signals, and phase noise all degrade EVM, and therefore EVM provides a comprehensive measure of an RFIC’s quality of use in digital communications. New wireless standards with large instantaneous bandwidth...

Evidence-based veterinary medicine (EVM) is an evolving discipline in veterinary medicine so it is important to periodically "benchmark" opinion about EVM across the profession. An international survey to assess veterinarians' awareness of EVM was conducted. Veterinarians were surveyed via an online questionnaire (all countries) or a postal questionnaire (UK only). Participants were asked wheth...

Fourth Generation (4G) Wireless System will integrate heterogeneous wireless overlay systems i.e. interworking of WLAN/ GSM/ CDMA/ WiMAX/ LTE/ etc with guaranteed Quality of Service (QoS) and Experience (QoE).QoS(E) vary from network to network and is application sensitive. User needs an optimal mobility solution while roaming in Overlaid wireless environment i.e. user could seamlessly transfer...

Earned Value Management Method (EVM), widely used in the world, is a project management method of costschedule integrated control. But the traditional EVM sometimes cannot provide an accurate result. In this paper, a practical method is given to analyze the project performance, in which the Network Diagram Method and the Critical Path Method have been introduced into EVM system that can better ...

Long Term Evolution (LTE) has been introduced by 3 rd Generation Partnership Project and dominates the 4 th generation of mobile telecommunication network. In this paper our work is unique in providing a detailed performance study based on NI PXIe – 5644 KIT. Our performance study includes FDD and TDD operation modes for uplink and downlink transmission in physical channel, data modulation, EVM...

The gas mechanism in Ethereum charges the execution of every operation to ensure that smart contracts running in EVM (Ethereum Virtual Machine) will be eventually terminated. Failing to properly set the gas costs of EVM operations allows attackers to launch DoS attacks on Ethereum. Although Ethereum recently adjusted the gas costs of EVM operations to defend against known DoS attacks, it remain...
