Earned Value Management (EVM) is a well-known cost and schedule management technique in government and defense industry projects. Its usage, however, is not as wide spread in the general software industry. In this paper we explore some of the shortcomings in EVM and suggest several improvements in the application of EVM in software development projects. In particular, we analyze the nature of s...

In order to cope with the rapid changes in the world, enterprises utilize project management methodology to globally outsource their works and to evaluate their internal and external work performance. Of all the project management techniques, Earned Value Management (EVM) is the major one that provides a method to evaluate project performance by integrating schedule and cost of work packages. E...

This paper deals with the performance analysis of HOM (higher order modulation) in LTE-A system. Firstly, we analyzed the requirement of HOM in small cell deployment, and then we analyzed the problem of EVM (Error Vector Magnitude) modeling in LTE system. With the assumption of small cell deployment, some link level simulation results are proposed, where the impacts of EVM on different MCS (mod...

Smart contracts in Ethereum are executed by the Ethereum Virtual Machine (EVM). We defined EVM in Lem, a language that can be compiled for a few interactive theorem provers. We tested our definition against a standard test suite for Ethereum implementations. Using our definition, we proved some safety properties of Ethereum smart contracts in an interactive theorem prover Isabelle/HOL. To our k...

The lack of integrated project control techniques covering both qualitative and quantitative indices is one of the most important reasons leading to unfinished projects under predetermined schedules and expected budgets. Two modern techniques proposed in project control—the critical chain method and buffer management (CCM/BM), and the earned value analysis or earned value management and earned ...

Standards for modern digital CDMA communication systems specify limits on the error vector magnitude (EVM) of the transmitted signal at the transmitter, whereas performance at the receiver is characterized by the bit error rate (BER). Traditionally, RF receiver specification defines limits on amplitudeand phase ripple over a certain bandwidth, IP3, IQ-mismatch, DC-offset, etc. Unfortunately, th...

Ethereum is a cryptocurrency framework that uses blockchain technology to provide an open distributed computing platform, called the Ethereum Virtual Machine (EVM). EVM programs are written in bytecode which operates on a simple stack machine. Programmers do not usually write EVM code; instead, they can program in a JavaScript-like language called Solidity that compiles to bytecode. Since the m...

This paper proposes a smart way of handling the Electronic Voting Machine (EVM) theft problem by having a wireless network based security and monitoring system using WPAN, RF signal strength, MEMS motion sensors and GSM technology. The proposed system consists of EVM units each equipped with a MEMS motion sensor forming a WPAN network based on star topology with the coordinator node acting as t...

Increasing complexity of software applications forces researchers to look for automated ways of programming and adapting these systems. Self-adapting, self-organising software system is one of the possible ways to tackle and manage higher complexity. A set of small independent problem solvers, working together in a dynamic environment, solving multiple tasks, and dynamically adapting to changin...

We propose a computational cognitive Extended Visual Memory (EVM) model for a Computer-Aided Vision (CAV) framework to assist human in vision-related tasks. The CAV framework exploits wearable sensors such as cameras, GPS and ambient computing facilities to empower a user’s vision and memory functions by answering four types of queries central to visual activities. Learning of EVM relies on bot...
