The demand for janitorial robots has gone up with the rising affluence and increasingly busy lifestyles of people [1], both in offices and personal homes. All too often people forget to switch off lights, close doors, throw away garbage and so on; this is where a janitorial robot would come in handy. This kind of robot must have the necessary characteristics of being able to autonomously naviga...

Parallel applications can speed up their execution by accessing resources hosted by multiple autonomous providers. Applications following the message passing model demand processors to be available at the same time; a problem known as resource coallocation. Other application models, such as workflows and bag-of-tasks (BoT), can also benefit from the coordinated allocation of resources from auto...

This paper demonstrates the applicability of reinforcement learning for first person shooter bot artificial intelligence. Reinforcement learning is a machine learning technique where an agent learns a problem through interaction with the environment. The Sarsa( ) algorithm will be applied to a first person shooter bot controller to learn the tasks of (1) navigation and item collection, and (2) ...

In this paper we describe the design and implementation of a bot to play the arcade game Breakout. Instead of manually writing the bot, we use reinforcement learning techniques to learn a strategy by repeated sessions of Breakout where the learner is rewarded for advancing through the game and punished for losing. We show that our bot’s game performance increases with repeated plays, though it ...

PURPOSE To quantitatively evaluate the pulse waveform changes in macular choroidal blood flow by using laser speckle flowgraphy (LSFG) with regression of acute central serous chorioretinopathy (CSC). METHODS This retrospective observational case series included 20 eyes of 20 patients with acute CSC. Laser speckle flowgraphy was performed at baseline and after 6 months. On the LSFG monochrome ...

Botnets are a major threat to the security of computer systems and the Internet. An increasing number of individual Internet sites have been compromised by attacks from all across the world to become part of various kinds of malicious botnets. The Internet security research community has made significant efforts to identify botnets, to collect data on their activities, and to develop techniques...

Exploitation of Best Effort Distributed Computing Infrastructures (BE-DCIs) allow operators to maximize the utilization of the infrastructures, and users to access the unused resources at relatively low cost. Because providers do not guarantee that the computing resources remain available to the user during the entire execution of their applications, they offer a diminished Quality of Service (...

We consider (subclasses of) polynomial bottom-up and top-down tree series transducers over a partially ordered semiring A = (A,⊕, ,0,1, ), and we compare the classes of tree-to-tree-series and o-tree-to-tree-series transformations computed by such transducers. Our main result states the following. If, for some a ∈ A with 1 a, the semiring A is a weak a-growth semiring and either (i) the semirin...

Over the years, many private sector participation (PSP) models have been evolved for infrastructure procurement and the Build-Operate-Transfer (BOT) model is one of the most common approaches used for the same. Private infrastructure projects under BOT arrangement have a complex risk profile and to a considerable extent, the success of any BOT project is influenced by the degree to which variou...
