This is a conceptual study on GST that elaborates the previous tax structure in India and problems associated with it, basics of the GST and how it will solve the present problems. This study also discusses the GST structure, benefits and the key issues related to it. This study brings out that how GST would bring down the cascading effects of present tax structure and reduce overall tax burden on business and consumers. GST would be overall beneficial to industry, trade, agriculture, exports. The key issues for businesses would be to assess the nuances of GST and its impact on particular business to chart out effective strategies for smooth transition to GST.

To escape the requirement for exhaustive instruction and stipulated preference ordering, a robot’s operation must involve choices between alternative actions, guided by goals. We describe a robot that learns these goals from humans by considering the timeliness and context of instructions and rewards as evidence of the contours and gradients of an unknown human utility function. In turn, this underlies a choice-theory based rational preference relationship. We examine how the timing of requests, and contexts in which they arise, can lead to actions that pre-empt requests using methods we term contemporaneous entropy learning and context sensitive learning. We provide experiments on these two methods to demonstrate their usefulness in guiding a robot’s actions.

We see that vector functions of position can be differentiated to give vector velocities and accelerations. We define frames of reference and see how the motion of a particle in a rotating frame can be represented in ‘world axes’. Generalised coordinates are mentioned, though a more mathematical treatment is to be found in the second appendix.

It was the result of a long and hard campaign spanning many years. In Paris, over 30 years ago the ‘Palais de la Decouverte’ had enticed youngsters to experiment with electricity, mechanics and even relativity with hands-on exhibits. For many years the British science museums have warned ‘Do not touch.’ At last exhibitions such as Intech are starting to spring up, no doubt helped by the growing alarm at the shortage of young students opting for science and engineering specialisations.

This paper discusses the design and possible gaits of such a robot.

At a time when universities are keen to encourage secondary school students into science and engineering disciplines, and schools are looking to bolster their technology programs, such competitions provide a win-win scenario. The major di#culties in establishing such a competition include #1# devising an inexpensive robot and associated task that challenges the student, #2# raising the skill level of teachers to a point where they are con#dent to run such an activity and #3# establishing a broad base of expertise to support large numbers of participants. In this paper we detail the development, features and outcomes of the Robot Bilby Competition. The use of workshops and school visits to impart the necessary skills to te...

Four types of inattentive students are described and common reasons for their lack of attention in class are discussed. Each individual student possesses different levels of 'intelligence' or talents. Unfortunately, only a few of these are promoted, developed and assessed in most education. Fun and entertaining video games have clearly demonstrated the potential to hold the attention of students for long periods of time. This attribute can be of great value if imparted to teaching material. Some game design strategies are outlined, together with an overview of the tools that teachers will need to learn in order to develop such games.
