in this paper we introduce continuous $g$-bessel multipliers in hilbert spaces and investigate some of their properties. we provide some conditions under which a continuous $g$-bessel multiplier is a compact operator. also, we show the continuous dependency of continuous $g$-bessel multipliers on their parameters.

Does trade liberalization foster total factor productivity (TFP) growth in the manufacturing sector? Does sectoral trade orientation determine sectoral TFP levels and growth rates? These questions are addressed using pooled pre-and post-liberalization panel data from Cameroonian firms of eight manufacturing industries. A single production function for the whole manufacturing sector is estimated...

Improved water supply, sanitation and hygiene used in combination are effective at achieving better health for poor people in developing countries. However, donor policy has been dominated by interventions in water supply, at the expense of achieving the potential health benefits of improved sanitation and hygiene. Commitments recently made by the international community require greater emphasi...

In this paper a new design of full adder cell based on Sense Energy Recovery concept using novel exclusive NOR gates is presented. Low-power consumption and delay are targeted in implementation of our design. The circuit designed is optimized for low power at 0.18-μm and 0.09 μm CMOS process technologies in full custom environment. The new circuit has been compared to the existing work based on...

Design of portable battery operated multimedia devices requires energy-efficient multiplication circuits. This paper proposes a novel architectural technique to reduce power consumption of digital multipliers. Unlike related approaches which focus on multiplier transition activity reduction, we concentrate on dynamic reduction of supply voltage. Two implementation schemes capable of dynamically...

Portable electronic systems require low-voltage low-power building blocks. An important building block is an A/D converter. ∆Σ ADCs provide an efficient way of trading off speed for resolution. The switched opamp (SO) technique allows design of switched-capacitor (SC) circuits at very low supply voltage without the use of multithreshold technologies or voltage multipliers to drive the switches ...

Multiplier is an important block of wireless communication system. In many applications there is a need to mix the signals of different frequencies or signals of different types, which emphasises the use of mixers or multipliers for different RF applications. MOS analog multiplier with less number of transistors which can operate at ISM Band frequency with high linearity is proposed. An ISM ban...

We consider the contribution of sectoral shocks to post-war US unemployment movements in a dynamic factor framework. Whereas previously published estimates of the contribution of sectoral shocks to unemployment relate to a particular theory of unemployment, our approach is sufficiently general to encompass almost any theory. We estimate our model in the frequency domain and use data on unemploy...

Firm births and deaths are interrelated. Johnson and Parker (1994) have summarized the various causality relationships according to three different effects: (1) the Multiplier, (2) the Competition and (3) the Marshall effect. This article proposes an enlarged analytical framework by introducing the sectoral and cross-sectoral dimensions of firm demography. The expected interrelationships betwee...

In this paper, we developed a supply chain network game theory model with differentiated products and transportation costs in the case of time-based oligopolistic competition. The firms are profit-maximizers and have, as their strategic variables, the product shipments and the guaranteed delivery times to the consumers at the demand markets with the guaranteed delivery times never exceeding the...
