Impact of ATM Service on Customer Perception and Satisfaction of Indian Banks
. Indian banking sector has completely changed. It has undergone much technological advancement that makes banking easy. Technological advancements are important but at the end what build customer satisfaction is proper management, employee behavior and customer relationship handling. Customer satisfaction is a sum of many variables that is many factors together leads to customer satisfaction. This modern electronic banking has completely changed the concept and functioning of banking system in India. Indian banking has moved from cash economy to cheque to and finally to the use of plastic cards. The customer satisfaction is dependent on customer awareness to a lot of extent. An unaware customer has less knowledge and therefore they cannot use the facilities completely even if they have it at their disposal. Customers prefer public sector banks when they are looking for trust and security and reliability. When it comes to speed, advancements and up gradation people shits from public sector banks to private sector banks. Customer gets satisfied only when they get quality service from the brand they are dealing with. This is very important for the marketers or the service providers as this leads to consumer satisfaction which benefits them and this brings loyalty to the brand enhancing the brand positioning. This research is important because new modern era has made people technology savvy they start their day with technology and end with technology therefore it is important to see the perception of users towards various factors of ATM. This research is conducted to see the highlighting factors that have direct impact on ATM services
Lyot-based Low Order Wavefront Sensor: Implementation on the Subaru Coronagraphic Extreme Adaptive Optics System and its Laboratory Performance
High throughput, low inner working angle (IWA) phase masks coronagraphs are
essential to directly image and characterize (via spectroscopy) earth-like
planets. However, the performance of low-IWA coronagraphs is limited by
residual pointing errors and other low-order modes. The extent to which
wavefront aberrations upstream of the coronagraph are corrected and calibrated
drives coronagraphic performance. Addressing this issue is essential for
preventing coronagraphic leaks, thus we have developed a Lyot-based low order
wave front sensor (LLOWFS) to control the wavefront aberrations in a
coronagraph. The LLOWFS monitors the starlight rejected by the coronagraphic
mask using a reflective Lyot stop in the downstream pupil plane. The early
implementation of LLOWFS at LESIA, Observatoire de Paris demonstrated an open
loop measurement accuracy of 0.01 lambda/D for tip-tilt at 638 nm when used in
conjunction with a four quadrant phase mask (FQPM) in the laboratory. To
further demonstrate our concept, we have installed the reflective Lyot stops on
the Subaru Coronagraphic Extreme AO (SCExAO) system at the Subaru Telescope and
modified the system to support small IWA phase mask coronagraphs (< 1 lambda/D)
on-sky such as FQPM, eight octant phase mask, vector vortex coronagraph and the
phase induced amplitude apodization complex phase mask coronagraph with a goal
of obtaining milli arc-second pointing accuracy. Laboratory results have shown
the measurement of tip, tilt, focus, oblique and right astigmatism at 1.55 um
for the vector vortex coronagraph. Our initial on-sky result demonstrate the
closed loop accuracy of < 7 x 10-3 lambda/D at 1.6 um for tip, tilt and focus
aberrations with the vector vortex coronagraph.Comment: 9 pages, 9 Figures, Proc. of SPIE Astronomical Telescopes +

Automatic Solar Tracking System with AVR Microcontroller based Street Light
This paper presents the design of a solar tracking system driven by an AVR microcontroller. This project is done by two ways of tracking system, manual and auto tracking. This project is very useful for street light in the campus and villages. The solar panel converts the sun light into the electrical energy, because sun is a very good source of different energies. And the solar energy is the best technique for renewable energy. Basically the energy sources are two types such as conventional energy sources and non-conventional energy sources. Coal, petroleum, natural gas etc. are example of conventional energy sources and solar cell, fuel cells, thermo-electric generator, thermionic converter, solar power generation, wind power generation, geo-thermal energy generation etc. are example of non-conventional energy sources. In developing countries where electricity supplies are inadequate, renewable energy can offer an alternative to expensive extensions of the grid to sparsely populated or rural areas, or a contribution to the grid-based energy mix to meet rapidly expanding electricity demand in urban areas. This work presents an autonomous street lighting system based on solar energy as primary source, batteries as secondary source, and light emitting diodes as lighting source. This system is being presented as an alternative for remote localities, like roads and crossroads
