Body part terms in Jahai

This article explores the lexicon of body part terms in Jahai, a Mon-Khmer language spoken by a group of hunter–gatherers in the Malay Peninsula. It provides an extensive inventory of body part terms and describes their structural and semantic properties. The Jahai body part lexicon pays attention to fine anatomical detail but lacks labels for major, 'higher-level' categories, like 'trunk', 'limb'

Utfästelser räcker inte

Det är nedslående att Cecilia Malmström givit upp kampen när det gäller fri- och rättigheter på nätet, skriver politiker och nätdebattörer. Den rättssäkerhet vi efterfrågar är en sådan som skyddar yttrandefriheten.

A Sparse Approach for Estimation of Amplitude Modulated Sinusoids

We consider the problem of spectral analysis of signals composed of sums of multiple amplitude modulated, possibly harmonically related, sinusoids using a sparse approach. By separating the nonlinear frequency variables using a dictionary of possible frequency components as well as a spline basis for the amplitude modulation, results in a convex criterion which can be efficiently solved without

A Flexible FFT Processor

In this paper a flexible FFT processor for OFDM systems is presented. In future wireless systems using OFDM each terminal should be able to handle a wide range of different applications, from pure voice communication to high-speed data transfers, with as little overhead in power consumption and protocol procedure as possible. As the terminals will be battery powered and should be cheap to manufact

Proton-Conducting Sulfonated Aromatic Ionomers and Membranes by Chemical Modifications and Polycondensations

Popular Abstract in Swedish Växthuseffekten och klimatförändringar har de senaste decennierna påskyndat forskning och utveckling av alternativa energikällor, däribland bränslecellen. En första skiss på en bränslecell föddes redan på 1830-talet. Det dröjde dock till 1950-talet innan den första kommersiella bränslecellen användes i ett av NASAs projekt. I Sverige har forskning runt bränsleceller medProton-exchange membrane fuel cells (PEMFC)s are increasingly regarded as promising environmentally benign power sources. Intensive development is today directed towards reducing the cost and increasing the durability of the fuel cell, as well as expanding the operational window for the PEMFC for a range of applications. The proton-conducting membrane is one of the key components in the PEMFC. The
