A 65nm CMOS 282uW 915MHz direct conversion receiver front-end

Abstract in UndeterminedThis paper presents an inductorless ultra-low power radio receiver front-end intended for applications such as sensor networks and medical implants. It consists of low noise amplifier, quadrature mixer, and a frequency divider for the generation of quadrature local oscillator signals. The power consumption is just 282μW from a 0.9V supply when it operates in the 915 MHz ISM

Definition of landscape erosion units using a structural classification OASIS of Landsat TM satellite imageries, case study Lebanon.

Soil erosion by water is a major cause of landscape degradation in semi-humid to semi-arid Mediterranean environments. Terrain particularly susceptible to the phenomenon witness a combination of erosive soil, unconsolidated rock type, steep slope, high rainfall intensity, active tectonic movement, rapid land use change and intense human interference. Current erosion models (e.g. USLE, RUSLE) are b

Adaptive Resource Scheduling for Energy Efficient QRD Processor with DVFS

This paper presents an energy efficient adaptive QR decomposition scheme for Long Term Evolution Advance (LTE-A) downlink system. The proposed scheme provides a performance robustness to fluctuating wireless channels while maintaining lower workload on a reconfigurable hardware. A statistic based algorithm-switching strategy is employed in the scheme to achieve workload reduction and stable comput

Existence of Minimum Upcrossing Controllers

An optimal stochastic control problem that minimizes the probability that a signal upcrosses a level is solved by rewriting it as a one-parametric optimization problem over a set of LQG control problem solutions. Finding the optimal controller can be interpreted as finding an optimal costing transfer function. The existence of the optimal controller is investigated in a constructive way, and it is

Betydelse av nedlagd studietid samt inlärnings- och studiestrategier för nya ingenjörers studieresultat under första terminen

I studien har vi gjort en inventering av inlärnings- och studiestrategifaktorer såsom oro, attityder, koncentration, motivation, studiestöd och tidsplanering bland nybörjarstudenter vid Lunds tekniska högskola (LTH) och studerat hur de förändras under första terminen. Vidare har vi studerat hur självstudietiden påverkar studieresultat och om det finns samband med inlärnings och studiestrategifakto

Small scale experiments and theoretical aspects of flame extinguishment with water mist

The present study focuses on extinction of flames with water mist where surface cooling effects are neglected i.e. water mist as a total flooding system where the direct spray cannot reach and cool all burning items in the protected volume. The study includes a survey of the production and properties of water mist such as different types of nozzles and means to describe droplet size distribution.
