Cable Connection

This paper explores the cost-effectiveness of various ways to connect users to the Internet. Three methods are analyzed: cable connection, GSM connection and Wi-Fi mesh connection. For these methods, a mathematical model is constructed that allows you to evaluate: return on investment, company profits, risk fear ratios and regrets about lost profits. The indicated calculations are carried out for 100 users in each connection method. The study of economic efficiency will be carried out by assessing the values of the parameters NPV, PI and IRR. According to the classical approach to assessing the effectiveness of projects, when implementing projects in cities, a connection using Wi-Fi mesh networks has higher relative project performance indicators (PI and IRR), but a lower NPV indicator than a project for a cable connection to the Internet. In conditions of low population density, the project for the implementation of the Internet by Wi-Fi mesh networks is more profitable in all considered indicators (NPV, PI, IRR) than the project for the implementation of the Internet via cellular communication.

Abstract Currently, the blueberry crop systems are continuous diversifing due to the growing demand for fruit on the market as well as the willingness of farmers to invest in profitable blueberries business. The need to extend the fresh-consumption period of blueberry fruits has made crop protection systems be considered appropriate for high-quality and valuable fruits. In the present work, we have proposed to compare the economic efficiency of three blueberry production systems as follows: the normal intensive cultural system in beds, the superintensive cultural system in pots and the superintensive cultural system in pots and plastic covered (high tunnel). The analyze of the cost and profitability of blueberry has been done according to the crop system, taking into consideration several elements such as: the number of plants per hectare, the total duration of the exploitation, the value of the investment, the yield and the cost of production etc. Further more, considering the average sale price of the blueberry fruits in Romania, we have calculated the net annual return, the annual return rate, the cost recovery period, total operating profit, economic return on investment, and average return on investment. We observed that as much the degree of intensification has increased, the value of investment was higher and the spendings has increased too. Blueberry pot production systems with or without plastic protection are especially recommended for smaller surfaces, which in this way can boost the value and their economic potential.

The Internet was supposed to fragment audiences and make media monopolies impossible. Instead, behemoths like Google and Facebook now dominate the time we spend online—and grab all the profits from the attention economy. This book explains how this happened. It sheds light on the stunning rise of the digital giants and the online struggles of nearly everyone else—and reveals what small players can do to survive in a game that is rigged against them. The book shows how seemingly tiny advantages in attracting users can snowball over time. The Internet has not reduced the cost of reaching audiences—it has merely shifted who pays and how. Challenging some of the most enduring myths of digital life, the book explains why the Internet is not the postindustrial technology that has been sold to the public, how it has become mathematically impossible for grad students in a garage to beat Google, and why net neutrality alone is no guarantee of an open Internet. It also explains why the challenges for local digital news outlets and other small players are worse than they appear and demonstrates what it really takes to grow a digital audience and stay alive in today's online economy. The book shows why, even on the Internet, there is still no such thing as a free audience.

The Impact

The quality of the software can be measured by its return on investment. Factors which may affect the return on investment (ROI) is the tangible factors (such as the cost) dan intangible factors (such as the impact of software to the users or stakeholder). The factor of the software itself are assessed through reviewing, testing, process audit, and performance of software. This paper discusses the consideration of return on investment (ROI) assessment criteria derived from the software and its users. These criteria indicate that the approach may support a rational consideration of all relevant criteria when evaluating software, and shows examples of actual return on investment models. Conducted an analysis of the assessment criteria that affect the return on investment if these criteria have a disproportionate effort that resulted in a return on investment of a software decreased.

Risk Categories

Public agencies generally let construction contracts to the lowest responsible, responsive bidder. In following this practice, agencies recognize there are higher risks of cost growth in awarding to either unusually low bids or to certain “claim-conscious” bidders. Despite this awareness, there are few documented studies supporting or quantifying the presence of these perceived competitive procurement risks. This research undertakes that specific task. First, bids and bidders on a sample of Alabama highway projects are grouped into risk categories by information available at the project bid opening—well in advance of any potential contract award— and without considering actual project performance data. Second, the cost growth experiences of these projects are statistically analyzed based upon these risk groupings. The results indicate that cost growth on Alabama highway projects is significantly more likely when projects are awarded to unusually low bids or to certain bidder types. A similar study performed earlier on Texas highway projects provides nearly identical results. This type of analysis and the derived information can be used by public agencies to amend the procurement process and objectively disqualify unusually low bids or questionable bidders without abandoning competitive procurement principles.
