Abstract. The Twente region in the east of Netherlands has a network with 20 soil monitoring stations that been utilized for validation Soil Moisture Active/Passive (SMAP) passive-only moisture products. Over period from April 2015 until December 2018, seven covered by SMAP reference pixels have fairly complete data records. Spatially distributed simulations Dutch National Hydrological Model de...

Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...

The purpose of this study was to choose between two popular models of skeletal muscle: one with the parallel elastic component in parallel with both the contractile element and the series elastic component (model A), and the other in which it is in parallel with only the contractile element (model B). Passive and total forces were obtained at a variety of muscle lengths for the medial gastrocne...

Adolescence may be defined as the period of life 'rom the end of childhood, and indicated physically by the bodily changes associated with puberty, continuing until full physical development is achieved, and adult status in society is recognised. Unfortunately there is incomplete agreement as to the time-period involved. Some authors (Sandstrom) consider the years from 12-16, the age 10-12 bein...

We argue in favor of the presumed c o m m i t protocol by proposing two new presumed commit variants that sign$cantly reduce the cost of logging activities associated with the original presumed commit protocol. Furthermore, for read-only transactions, we apply our unsolicited updatevote optim’zationand show that the cost associated with this type of transactions is the same in both presumed com...

Introduction. Since the time of Riemann, there has been a close interplay between the study of the geometry of complex algebraic curves (or, equivalently, compact Riemann surfaces) and the topology of 2-manifolds. These connections arise from the uniformization theorem, which asserts that every simply connected Riemann surface is conformally equivalent to either the Riemann sphere, the plane, o...

Dynamic replication can be used to reduce bandwidth consumption and access latency in high performance “data grids” where users require remote access to large files. Different replication strategies can be defined depending on when, where, and how replicas are created and destroyed. We describe a simulation framework that we have developed to enable comparative studies of alternative dynamic re...

Software measures are of paramount importance to evaluate both processes and products. However, collecting such data requires a large effort and this activity produces benefits only in the long term. For these reasons, companies have to use automated tools able to collect data without affecting both the productivity and the process. This approach is useful to reduce the effort related to the me...

It is well known that passive walking robot can dynamically walk down with a steady gait by only powered gravity. The dynamics of passive walking has interesting characteristics of stability and bifurcation. Since passive gait is natural motion, investigation of passive walking may lead us to understand human locomotion and design for active walking robot. In this paper, the dynamics of passive...
