A popular technique for tolerating malicious faults in open distributed systems is to establish small groups of participants, each of which has a non-faulty majority. These groups are used as building blocks to design attack-resistant algorithms. Despite over a decade of active research, current constructions require group sizes of O(logn), where n is the number of participants in the system. T...

We argue for breaking data-parallel jobs in compute clusters into tiny tasks that each complete in hundreds of milliseconds. Tiny tasks avoid the need for complex skew mitigation techniques: by breaking a large job into millions of tiny tasks, work will be evenly spread over available resources by the scheduler. Furthermore, tiny tasks alleviate long wait times seen in today’s clusters for inte...

A distinctive pattern of small-scale marine magnetic anomalies (25-100 nT amplitude, 8-25 km wavelength: tiny wiggles) is superimposed on the more generally recognized seafloor spreading pattern between anomalies 24 and 27 in the Indian Ocean. By normalizing and stacking multiple profiles, it is demonstrated that this pattern of tiny wiggles is a high-resolution recording of paleodipole field b...

A low-cost and portable vector network analyzer (VNA) which covered operating frequency between 1MHz to 3GHz is used for vector reflection coefficient and standing wave ratio (swr) of the various microstrip antennas. This paper presents measurements of various ultra wideband (uwb) microstrip antennas for applications in biomedical field. Selection of antenna is an important key for detection of...

Trade secret and contract law are inadequate remedies for protecting recordings of single notes created without an underlying composition use in digital instruments such as keyboards, drum pads, audio workstations. These should be afforded the same rights under copyright any other sound recordings. Selection arrangement sounds to facilitate playing specific compositions (i.e. custom programming...

For this thesis, different algorithms were created to solve the problem of Jop Shop Scheduling with a number of constraints. More specifically, the setting of a (simplified) car workshop was used: the algorithms had to assign all tasks of one day to the mechanics, taking into account minimum and maximum finish times of tasks and mechanics, the use of bridges, qualifications and the delivery and...

Java is widely applied from the small embedded devices to enterprise systems nowadays due to its object-oriented features and corresponding advantages of security, robustness, and platform independence. Java programs are compiled into Java Bytecodes, which are executed in the Java virtual machine. Among the current hardware or software solutions to the Java virtual machine, the object-oriented ...
