This paper outlines some reasons for why gestures are relevant to the study of SLA. First, given cross-cultural and cross-linguistic gestural repertoires, gestures can be treated as part of what learners can acquire in a target language. Gestures can therefore be studied as a developing system in their own right both in L2 production and comprehension. Second, because of the close link between ges

Indonesia came a long way under Suharto but it became very clear in 1997 that the development process was far from finished. In fact, the crisis showed how vulnerable the Indonesian economy still was. A core issue in development policy in Indonesia was the transformation of the agricultural sector and great efforts were put into this in the early Suharto era. With achievement of self sufficiency o

This paper presents a method based on the phase dierence of arrival and the non-linear least square estimation to lo- calize a radio-frequency (RF) source, e.g a wireless capsule endoscope, inside the human body. The phase dierence of arrival at multiple frequencies of a signal is used to estimate the distance of the source to a receiver. The linear least square estimation is used to estimate the

In this paper, the thermal impact of using different steel laminations in the stator and the rotor of a permanentmagnet assisted synchronous reluctance machine designed for an automotive application is studied. In this regard, two main parameters of the steel lamination materials, thickness and amount of alloy content in weight percent, are studied. Frequency characteristics of the iron losses of

In this paper, an inverse source reconstruction method with great potential in radome diagnostics is presented. Defects, e.g. seams in large radomes, and lattice dislocations in frequency selective surface (FSS) radomes, are inevitable, and their electrical effects demand analysis. Here, defects in a frequency selective radome are analyzed with a method based on an integral formulation. Several fa

With larger penetrations of wind power, the uncertainty increases in power systems operations. The wind power forecast errors must be accounted for by adapting existing operating tools or designing new ones. A switch from the deterministic framework used today to a probabilistic one has been advocated. This two-part paper presents a framework for risk-based operations of power systems. This framew
