1 Description of the Model We consider an autonomous lawnmower that uses a probability bias to avoid patterns on lawns. This mower is started on a rectangular grassed area. When it reaches the border of the area, it changes its direction. To prevent the mower from following a simple cycle pattern, this direction is randomly biased, such as to ensure that finally the entire area has been cut. A ...

1 Description of the Model We consider in this test case an extension of the thermostat example described in [1]. A sketch of the model is depicted in Figure 1 There are four modes: Cool, Heat, Check and Error. The latter mode models the occurence of a failure, where the temperature sensor gets stuck at the last checked temperature.The set of variables {t, x, T } where T represents the temperat...

This year, 2015, marked 40 years since the first routine vaccination schedule was approved in Spain. Although the vaccination schedules in the various Autonomous Communities are currently based on that proposed by the Inter-regional Council of the National Health System (CISNS), the differences between them are obvious, not only in terms of the age bands in which particular doses are administer...

ABSTRACT While aspe t{oriented approa hes draw their strength from improving modularity at the sour e ode level, their a eptan e for wide spread appli ation depends on a seamless embedding into the software life{ y le. When striving for an appropriate design notation for AOSD it is important to arefully balan e the abstra tion required by design with the pre ision required for implementing a gi...

The article presents a review on vision-based solutions for driver assistance. These solutions support the driver to keep safe travel conditions. They use diverse sensing modalities for the recognition of the environment around the vehicle. Upon detection a critical safety situation they supply the driver with the warning. Four assistance systems have been addressed: TSR Traffic Sign Recognitio...

Large-conductance Ca2+-dependent K+ (BKCa) channels are important regulators of electrical activity. These channels colocalize and form ion channel complexes with voltage-dependent Ca2+ (CaV) channels. Recent stochastic simulations of the BKCa-CaV complex with 1:1 stoichiometry have given important insight into the local control of BKCa channels by fluctuating nanodomains of Ca2+. However, such...

Chicken anaemia agent (CAA) was purified using differential centrifugation and successive cycles of equilibrium density gradient centrifugation using sucrose and CsCl. The purification method was dependent on the use of an antigen-detecting ELISA based on a CAA-specific monoclonal antibody. Virus particles banded at a density of 1.33 to 1.34 g/ml in CsCl and measured 23.5 +/- 0.8 nm in diameter...

Plant harvest is one of the most important management practices in constructed wetlands. In this study, we evaluated the impact of harvesting Phragmites australis (Cav.) Trin. ex Steudel on the activity and community structure of nitrifiers and denitrifiers in a free-water surface constructed wetland. The nitrifiers were targeted using bacterial and archaeal-amoA that encode ammonia monooxygena...

After 19 weeks on a mash diet nine of the 10 birds exhibited from two to 19 oral lesions. The majority of these lesions involved the total erosion of the buccal epidermis giving a total area of exposed dermis of 0.6 to 94.5 mm(2). This was accompanied by a significant reduction in the numbers of heterophils, monocytes and eosinophils. Birds with lesions also had significantly reduced concentrat...

Introduction. Chicken anaemia virus, CAV, was until recently the only member of the Gyrovirus genus. 6 novel gyroviruses, AGV2, HGyV1, and GyV3-6, have since been discovered in human and chicken samples. Methods. PCR amplification of the VP2 gene was used to detect AGV2/HGyV1, GyV3, and CAV in a range of clinical samples including stool, respiratory, CSF, and HIV-positive plasma. Screening of f...
