Since more than ten years, running is experiencing a boom accompanied by a proportional explosion of research in that field. Quantitative analysis is of critical interest for both clinical and sport science fields. Inertial measurement units (IMU) are now widely considered as an economical alternative for long assessment in real conditions. Detecting the instant at which the foot strikes the ground (initial contact) and the instant at which it leaves the ground (terminal contact) gives an access to many useful temporal parameters like the stance, the swing or the stride duration. In this thesis, an original algorithm to detect the main running temporal events is presented. This algorithm allows to detect initial contacts with a precision (median $pm$ interquartile range IQR) of 5 $pm$ 10 and $0 pm 5$ for terminal contacts. The absolute errors in the stride and stance durations are of -1.56 $pm$ 3\% and 0 $pm$ 1.32\%.

The history of international mathematical co-operation over the last hundred years - from the first international congress in 1897 to plans for the World Mathematical Year 2000 - is a surprisingly compelling story. For reflected in the history of the International Mathematical Union (IMU) is all the strife among world powers, as well as aspirations for co-operation among nations in an increasingly interdependent world. As early as the 1920s, the IMU embraced principles of political neutrality, inviting every national mathematical organisation to join, and this principle of non-discrimination, while sometimes sorely tried, has held the IMU in good stead. A number of issues - the Cold War, the conflict between the Peoples Republic of China and Taiwan, a divided Germany, problems in the emerging nations of Africa - at times led to attempts to influence the IMU Executive Committee in its decisions regarding membership, location of international congresses, committee assignments, handling of protests, and awarding the coveted Fields Medals. Yet throughout, the IMU has sponsored international congresses around the world, and Professor Lehtos gripping story is one of individuals, among them many of the great mathematicians of our century, united in the common purpose of advancing their science, told against the backdrop of world events.

Recent advances in electronics have led to sensors whose sizes and weights are such that they can be placed on living systems without impairing their natural motion and habits. They may be worn on the body as accessories or as part of the clothing and enable personalized mobile information processing. Wearable sensors open the way for a nonintrusive and continuous monitoring of body orientation, movements, and various physiological parameters during motor activities in real-life settings. Thus, they may become crucial tools not only for researchers, but also for clinicians, as they have the potential to improve diagnosis, better monitor disease development and thereby individualize treatment. Wearable sensors should obviously go unnoticed for the people wearing them and be intuitive in their installation. They should come with wireless connectivity and low-power consumption. Moreover, the electronics system should be self-calibrating and deliver correct information that is easy to interpret. Cross-platform interfaces that provide secure data storage and easy data analysis and visualization are needed.This book contains a selection of research papers presenting new results addressing the above challenges.

This volume presents the findings of three seasons of excavation in the 1980s at Kom el-Hisn "the mound of the fortress", in the northwest Nile Delta. This provincial community was often in the orbit of Memphis, the capital and administrative center of Egypt's Old Kingdom Period. Small areas of occupations of the First Intermediate and early Middle Kingdom periods were also excavated. One of the goals of the excavations was to complement and compare the substantial ancient textual record of this era with Kom el-Hisn's archaeological record because such evidence is sparse for Lower Egypt between about 2500 and 1800 BC. The findings presented here reveal the complexity of small Old Kingdom settlements in the context of the Memphite state organization and shed light on the changing relationships of this administrative centre with its provincial communities. Kom el-Hisn's faunal, floral, lithic and architectural remains are presented and discussed in detail, as are some theoretical and methodological issues relevant to this research.

The Six Day War in 1967 profoundly influenced how an increasing number of religious Zionists saw Israeli victory as the manifestation of God's desire to redeem God's people. Thousands of religious Israelis joined the Gush Emunim movement in 1974 to create settlements in territories occupied in the war. However, over time, the Israeli government decided to return territory to Palestinian or Arab control. This was perceived among religious Zionist circles as a violation of God's order. The peak of this process came with the Disengagement Plan in 2005, in which Israel demolished all the settlements in the Gaza Strip and four settlements in the West Bank. This process raised difficult theological questions among religious Zionists. This book explores the internal mechanism applied by a group of religious Zionist rabbis in response to their profound disillusionment with the state, reflected in an increase in religious radicalization due to the need to cope with the feelings of religious and messianic failure.

This open access book is about the shaping of international relations in mathematics over the last two hundred years. It focusses on institutions and organizations that were created to frame the international dimension of mathematical research. Today, striking evidence of globalized mathematics is provided by countless international meetings and the worldwide repository ArXiv. The text follows the sinuous path that was taken to reach this state, from the long nineteenth century, through the two wars, to the present day. International cooperation in mathematics was well established by 1900, centered in Europe.
