The justification of implementing PAPR reduction schemes in OFDM is discussed. Decreasing PAPR increases the efficiency of the linear power amplifier, yielding an increase in average power emitted and consequentially an increase in capacity. However, implementing a PAPR reduction scheme s such as Tone Reservation or Selective Mapping means a decrease in the payload bandwidth which causes a decr...

This paper argues that a risk averse of workers after-tax reservation wage the difference between her reservation wage and the tax needed to fund the unemployment insurance system when liquidity constraint binds exists and it is unique. The optimality of unemployment insurance based on the responsiveness of reservation wage to unemployment benefit shows the disincentive effect, i.e. higher unem...

Thyroid hormone (TH) treatment exerts beneficial effects on the cardiovascular system: it lowers cholesterol and LDL levels and enhances cardiac contractile function. However, little is known about the effect of TH on vascular function or the functional role of TH receptors (TRs) in the regulation of vascular tone. We have investigated the contribution of TRs to vascular contractility in the he...

{ The Dual Busy Tone Multiple Access (DBTMA) scheme was designed for decentralized networks such as Packet Radio Networks (PRN's). We use the RTS/CTS dialogue to reserve the channel in DBTMA. In addition, we use two busy tones to notify neighbor nodes of the ongoing transmission and reception after a successful channel reservation. Our analysis and simulations show that DBTMA provides higher ne...

Presently, orthogonal frequency division multiplexing (OFDM) as a multicarrier transmission system is widely used. Along with its advantages it has many disadvantages. One of its major drawback is high peak to average power ratio (PAPR). As with high PAPR the spectral efficiency of the high power amplifiers degrades. So it becomes necessary to maintain the efficiency of a wireless system to red...

Research is reported on the way in which Finnish speakers of English interpret the semantic/pragmatic meaning of the fall-rise intonation in spoken English. A set of constructed mini-dialogues were used for listening tests in which the test subjects were to interpret the “meaning” of the fall-rise tone. To obtain baseline data, a group of native speakers of English listened to the same material...
