In the presence of a peer-to-peer economy, the option of sharing an item is valuable for consumers. By retaining control over the shareability of its products a monopolist can set a sharing tariff in conjunction with the purchase price of the product, in order to extract state-contingent surplus from consumers: the shareability rent. Using an overlapping-generations model with heterogeneous con...
In light of the massive developments in Information Technology (IT) in the past few years, there has been a recent debate in the literature on the economic impact of IT. Of particular interest has been the role of the ‘New Economy’ sectors (hardware, software, and communications) in bringing about economic growth and productivity revival in the United States. While on a much smaller scale, Egyp...
applications such as high definition viedeo reproduction, portable computers, wireless, and multimedia demand, and ever-increasing need for ligh-frequency high-resolution and low-power analog-to-digital converters. flash, two-step flash, and pipeline convertors are fast but consume large amount of power and require large area. to overcome these problems, successive approximation converter blo...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
In a modern economy each branch of economic activity is inter-linked with other branches of activity. Measuring any one sector of an economy therefore usually involves drawing more or less arbitrary boundaries around that sector. This problem is particularly acute in relation to the food industry. Varying definitions of that industry are in common usage, so that any attempt to measure the size ...
This work proposes LEASE, a novel Mobile-P2P lease-based economic incentive model, in which data requestors need to pay the price (in virtual currency) of their requested data items to data-providers. In LEASE, data-providing mobile peers lease data items to other mobile peers in lieu of a lease payment. The main contributions of LEASE are three-fold. First, its lease model entices even those u...
When measuring the importance of the energy sector in a country’s nonfinancial business economy total (Graph 1), and among the 21 Member States with data available, Slovakia was the most specialised – in terms of both value added and employment – with the industry representing 14.8 % and 3.4% respectively of its non-financial business economy. By contrast, in terms of value added, the least spe...

the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
This work proposes LEASE, a novel Mobile-P2P lease-based economic incentive model, in which data requestors need to pay the price (in virtual currency) of their requested data items to data-providers. In LEASE, dataproviding mobile peers lease data items to free-riders, who do not have any data items to provide, in lieu of a lease payment. Thus, LEASE not only combats free-riding, but also enti...
