In this study, we measured the mobility distributions of cluster and intermediate ions with an ion spectrometer near a waterfall. We observed that the concentration of negative 1.5–10 nm ions was one-hundred fold higher than a reference point 100 m away from the waterfall. Also, the concentration of positive intermediate ions was found to be higher than that at the reference point by a factor o...

For hybrid inflationary potentials, we derive the tunneling rate from field configurations along the flat direction towards the waterfall regime. This process competes with the classically rolling evolution of the scalar fields and needs to be strongly subdominant for phenomenologically viable models. Tunneling may exclude models with a mass scale below 10 GeV, but can be suppressed by small va...

in recent decades, tourism has been considered as a way to decreasing tensions of urban life. this study tried to determine the effective factors in visitors' willingness to pay for asiab kharabeh fall by using tobit model. data set were obtained by completing questionnaires and interviewing with 125 individuals who visit the fall. according to the results 69.6 percent of visitors were rea...

The purpose of this document is to provide technical specifications concerned to the Design of the University Unified Inventory System - Web Portal, of the UIfA. The Team of Developers used a Feedback Waterfall approach to build up the system, under an Object Oriented paradigm. The architectural model followed was the Model-View-Controller, mixed with a Mapper layer between the database and the...

Starting from the Rational Unified Process RUP and the ARIS life cycle model the ARIS Unified Information System Development Process AUP is designed. Similar as the RUP is developed from the classic waterfall model as an iterative and incremental process to build software, the AUP is developed from the ARIS life cycle model as an iterative and incremental process to build business information s...

Researchers and practitioners alike agree that the waterfall approach to software development results in poor quality software systems. Unfortunately, the waterfall approach is inherently used in almost all of today’s development efforts resulting in system failures. The problem lies in the forward, linear development effort that produces inconsistent and incorrect specifications, designs, and ...

A new general concatenated code structure, containing both parallel and serially concatenated codes as special cases, is presented. The structure provides a unified framework for the analysis of concatenated codes and offers new degrees of freedom for code design. Performance analysis based on bounds on the error probability in the error floor region and suggestions for suitable design criteria...

We propose an analysis tool of the finite-length iterative turbo decoding algorithm. The proposed tool is a generalized EXIT chart based on the mutual information transfer characteristics of the extrinsic information in the iterative turbo decoding algorithm. The proposed tool can describe the probabilistic convergence behavior of the iterative decoding algorithm. By using this tool, we obtain ...

Software has been playing a key role in the development of modern society. Software industry has an option to choose suitable methodology/process model for its current needs to provide solutions to give problems. Though some companies have their own customized methodology for developing their software but majority agrees that software methodologies fall under two categories that are heavyweight...
