this paper examines the accuracy of valuation models in providing reasonable estimation of the market values of listed companies in tehran stock exchange (tse). six valuation models including gordon growth model, two stage dividend discount model, adjusted present value, price to earning ratio and residual income were examined in this study. in addition, three proxies represent the market value...

Due to the complexity of pricing in service industry, it is important provide an efficient framework for real-life and large-sized applications. To this end, we combined optimization approach with a regression-based machine learning method reliable integrated train formation problem under hybrid uncertainty. do so, firstly, model applied forecast ticket price passenger railway then, obtained us...

Urban public transportation systems in 26 selected Czech municipalities are studied using their timetables, location of stops, and price survey. The methodology processing is proposed. A set indicators describing spatial accessibility, performance, prices analysed mainly for relationships to the population with an indication which most deviate from common trends. proposed four-dimensional evalu...

Yeast histidine tRNA guanylyltransferase (TGT) catalyzes in the presence of ATP the addition of GTP to the 5‘ end of eukaryotic cytoplasmic tRNAHi” species. A study of the enzyme mechanism with purified protein showed that during the first step ATP is cleaved to AMP and PPi creating adenylylated TGT. In a second step the activated enzyme forms a stable complex with its cognate tRNA substrate. T...

This paper presents results from an impact analysis of the Ticket to Work (TTW) program, as implemented by the Social Security Administration (SSA) from 2002 through 2007. For new, young Social Security Disability beneficiaries, we use exogenous variation in the month of Ticket mailing to rigorously estimate impacts of TTW on beneficiary outcomes over a 48-month period following the start of Ti...

Online air ticket booking is a cognitively complex task even on fully-functional internet-access devices such as desktops, representing a repetitive multi-parametric search in the flights database and then browsing long lists of flights found, consisting of different carriers, prices, dates and times, to create an optimal combination of outbound and inbound flights. We present the results of re...

Cell nuclei are like gated communities—quite selective about who gets in. And understandably so, because if the wrong proteins showed up at the wrong time and place, the consequences could be disastrous. The standard procedure for moving large molecules that cannot diffuse from the cytoplasm into the nucleus is to use the transport proteins known as karyopherins as escorts. How do karyopherins ...

A Decision Support System based on Artificial Neural Network is developed to forecast the number of sleeping cars in rail transport. The inputs to the system consist of train route, month, type of sleeping car, number of berths (supply), number of departures, ticket price and GDP, while the output of the neural network is the number of sold tickets (demand). By comparing the results obtained th...
