...| Compensation and R&R: Current Issues and Proposed Reform | A Critique | Manish Gupta Roll No 13 | Current Issues and Proposed Reform The current Resettlement & Rehabilitation policy has set a very high threshold of 500 families or more together in plains and 250 families together in hills, Desert Development Programme (DDP) blocks, and the areas which have been mentioned in Schedule V and Schedule VI of the Constitution of India. This high threshold fails to capture the cases in which the family number is not as high as 500 in plains or 250 in cases of hills. This high threshold totally defeats the purpose of the Resettlement & Rehabilitation policy as it will still cause the families to be traumatized due to loss of land and in most of the cases, means of the livelihood and social status of the families. In Indian society, the families having land have always enjoyed a higher social status than the ones having less or no land at all. Displacement from the land also may result in the families losing the same society of people in which they have been living in prior to land acquisition. The Resettlement & Rehabilitation policy also failed to put stress on an option that causes non-displacement or minimum displacement for the execution of the project for which the land has been acquired from the landowners. The Resettlement & Rehabilitation policy also did not make any provision for prior assent of the affected people before forced displacement...

...form of affirmative action designed to improve the well-being of backward and under-represented communities defined primary by their ‘caste’ (quota-system based on ‘gender’ or ‘religion’). These are laws wherein the certain percentage of total available vacancies in educational institute or government jobs are set aside for people from backward communities and others like SC, ST, OBC are the primery beneficiaries of the reservation policy under the constitution. Reservations per say has really failed to deliver the intended objective. Which is to uplift the down trodden and reduce the huge gap between the forward and the backward class . In the almost 60 years of its existence it has kind of consolidated a deep rooted belief amongst the scheduled caste that it is their right to get quotas and freebies and they need not have to make efforts to acquire skills to be competitive .There is quota in education and there is quota in jobs. The entire approach has been flawed .Mostly because the original well intentioned reservation policy thought out by the framers of the constitution was manipulated by later order politicians solely with the intention securing votes.None of the government machinery's has bothered to evaluate the extent to which benefits have percolated.Instead of creating more schools and educational institutions it went about reserving quotas.If the govt had provided a high class free education ,they need not have bothered about reserving jobs for the SC AND ST,the SC...

...A Review of Induction Motors Pattinson Hayton California State University, Long Beach College of Engineering 12/03/2015 Thus far in Energy Conversion and Principles, the topics of direct current, or DC, and synchronous motors have been covered and discussed. A direct current exists in the field windings of both of these motors and an alternating current, or AC, exists in the armature windings of both of these motors. Electrical power is delivered right to the armature of a DC motor using a commutator, or the moving part of the rotary, in these motors. Because of this, a DC motor with this type of connection can also be referred to as a conduction motor. Conversely, if a motor receives power by induction, rather than by conduction, the motor is called an induction motor. An induction motor is therefore a type of transformer that possesses a rotary secondary winding. As discussed previously, both DC and synchronous motors are doubly-fed. An induction motor, however, is a singly-fed motor. With these motors being singly-fed, the construction of is different than that of other motors. These motors do not require slip-rings, a commutator, or brushes. With these components absent from induction motors, it is thus seen that there are no moving contacts between the stator and rotors, which is obviously quite different than the structure of DC and synchronous motors. Induction motors are useful due to their efficiency. The absence of brushes in induction motors eliminates...

The alternating current (AC) electric induction motor has been an industry workhouse for electromechanical conversion for over 100 years. This paper introduces the fundamental electric and mechanical principles of 5 phase AC induction motor. In this paper, a generalized formula is proposed for the selection of number of slots required for 5-phase alternative current (AC) machine design and the criterion for selecting the starting points of each phases. Keywords: Induction motor. Five phase, Stator winding. current. The power per phase is P = VP IP cosϕ and the total power is the sum of the amount of power in each phase.

...Mathematical induction is a method of mathematical proof typically used to establish that a given statement is true for all natural numbers (positive integers). It is done by proving that the first statement in the infinite sequence of statements is true, and then proving that if any one statement in the infinite sequence of statements is true, then so is the next one. The method can be extended to prove statements about more general well-founded structures, such as trees; this generalization, known as structural induction, is used in mathematical logic and computer science. Mathematical induction in this extended sense is closely related to recursion. Mathematical induction should not be misconstrued as a form of inductive reasoning, which is considered non-rigorous in mathematics (see Problem of induction for more information). In fact, mathematical induction is a form of rigorous deductive reasoning.[1] Contents [hide] 1 History 2 Description 3 Axiom of induction 4 Example 5 Variants 5.1 Starting at some other number 5.2 Building on n = 2 5.2.1 Example: product rule for the derivative 5.2.2 Example: Pólya's proof that there is no "horse of a different color" 5.3 Induction on more than one counter 5.4 Infinite descent 6 Complete induction 6.1 Transfinite induction 7 Proof of mathematical induction 8 See also 9 Notes 10 References [edit]History In 370 BC, Plato's Parmenides may have contained an early example of an implicit inductive proof.[2]...

...CHAPTER I The Problem and Its Setting Introduction Cookers can broadly be divided into two types, namely gas cookers and electric cookers. Electric cookers can also however also be sub-divided into three types, namely radiant coil cookers, solid disc cookers and ceramic top cookers. Gas cookers power is easy to adjust and response is instant, thus providing good temperature control. Consumption of gas varies depending on the size of the burners. This type of cooker is the least efficient of all the cookers. The main advantage of a gas cooker is that gas is relatively inexpensive. The main disadvantage is that these types of cookers are the least safe out of all the cookers. Radiant coil cookers are the most common of all the cookers. They are also the cheapest cookers to purchase initially. These types of cookers are heated by electrical resistance. These cookers are more efficient than solid disc cookers and ceramic top cookers. Solid disc cookers are similar to radiant coil cookers. They are just solid and fixed to the cooker. They do not need to be removed for cleaning. These elements have a greater thermal mass than radiant coil elements and are thus less efficient and have a slower response time. Ceramic top cookers have their elements below heat resistant ceramic glass. This improves appearance and improves cleaning. These types of cookers take longer to heat up than radiant coil and solid disc cookers. Their response is also slower than the above-mentioned cookers...

...Journal of Data Science 2(2004), 231-244 Estimating Vehicle Speed from Traffic Count and Occupancy Data Martin L. Hazelton University of Western Australia Abstract: Automatic vehicle detectors are now common on road systems across the world. Many of these detectors are based on single inductive loops, from which data on traffic volumes (i.e. vehicle counts) and occupancy (i.e. proportion of time during which the loop is occupied) are available for 20 or 30 second observational periods. However, for the purposes of traffic management it is frequently useful to have data on (mean) vehicle speeds, but this is not directly available from single loop detectors. While detector occupancy is related in a simple fashion to vehicle speed and length, the latter variable is not measured on the vehicles that pass. In this paper a new method for speed estimation from traffic count and occupancy data is proposed. By assuming a simple random walk model for successive vehicle speeds an MCMC approach to speed estimation can be applied, in which missing vehicle lengths are sampled from an exogenous data set. Unlike earlier estimation methods, measurement error in occupancy data is explicitly modelled. The proposed methodology is applied to traffic flow data from Interstate 5 near Seattle, during a weekday morning. The efficacy of the estimation scheme is examined by comparing the estimates with independently collected vehicle speed data. The results are encouraging. Key words: Bayesian inference, inductance...

...Induction and mentoring programs are a structured form of support for beginning educators. The two programs are linked together and complement each other for the security of lowering the attrition rate in beginning teachers. These two programs are offered to new teachers for a combination of support, new development and opportunities. Mentoring and induction programs are very similar, but their differences set them apart and each one can offer knowledge and experience for every new teacher. More and more school systems are creating quality induction and mentoring programs for new teachers with great success and this process is invaluable. Across the country the need for more quality teachers has been recognized and the support from successful induction and mentoring programs can make that need a reality. The New Teacher Center reports working with “teachers, administrators, universities, and other educational organizations to build induction and mentoring programs not only designed to support new teachers, but to have a lasting impact on classroom practices and the school communities.”(NTC, 2009) For an induction and mentoring program to have longevity, strategy and constant feedback are two vital components. When an induction and mentoring program are successful, teachers can easily integrate into the culture of the school full of confidence to respond to their own induction and mentoring plans. How does a mentoring program differ from an induction program? The induction...

Induction Step: Assume we form any postage i with 18 ≤ i ≤ n, with n ≥ 20.Consider forming n + 1 cents of postage. By strong induction hypothesis, since n ≥ 20, n − 2 ≥ 18, we then have n − 2 cents of postage. Adding single three cent stamp then gives n + 1 cents of postage. Hence proved 5) The assumption in the inductive step is that there always is minimum 1 3-cent stamp or minimum 2 4-cent stamps. Proof is also flawed since...

...Induction – Magnet through a Coil Activity P30 Purpose: Electromotive forces can be induced in a coil by changing the magnitude of the magnetic field within the coil, changing the area of the coil, or changing the angle between the magnetic field and the area of the coil. This lab used the first method of changing the magnitude of the magnetic field by dropping a magnet through a coil in order to induce an electromotive force. The EMF was measured as the magnet fell. The integral of EMF versus time gives the magnetic flux according to Faraday’s Law of induction. Faraday’s law of induction essential states that EMF is equal to the rate of change of magnetic flux. Some aspects of Lenz’s law were also investigated. Lenz’s law states that the direction of the current in a coil moves in the direction that causes a magnetic field that opposes the change in the magnetic field of the magnet. Procedure and Materials: The computer was set up by connecting the Voltage Sensor and the interface. A new activity was opened in Data Studio with a graph of Voltage versus Time. Automatic recording was set to begin recording once 0.05 volts was reached and stop at 0.4 seconds of elapsed time. The alligator clips were connected to the circuit board springs next to the induction coil. Data was recorded for three variations of the experiment. First, a single bar magnet was dropped through the coil starting with the south end approximately 2 cm above the coil. Then two magnets were dropped with...
