Does internet change the concept of education: An institute based cross sectional study to reveal the opinion of the students about classroom teaching and internet as an education

The Internet is the latest mode of communication technologies that have been widely adopted by the students and consequently has the potential to become a valuable resource to support their educational queries and communication with their peers. In our study, we tried to found out their view about learning through this new approach and conventional classroom teaching. An Institute based cross-sectional study was designed with all the 109 first year M.B.B.S students. After getting the ethics committee clearance and informed consent from the students, questionnaires were given to them. They responded according to the question asked. The data were analyzed in Microsoft Excel 2010 package. View of the students varies. They all appreciated both types of teaching, but weightage of each have some advantages of their own. Through this cross-sectional study result, we can conclude that “internet, if used judiciously on behalf of both teachers and student that could be powerful teaching aids.”

Structural behaviour of ferrocement self compacting concrete using M-sand under axial and lateral pressure load

Present Paper describes the structural performance of ferrocement self-compacting concrete tanks under pressure loads. The structural performance of the all tested tanks in terms of strength, cracking behavior and energy absorption was investigated. An experimental program was designed in the current work to examine the structural performance of ferrocement self-compacting concrete tanks under pressure loads. The self -compacted concrete is an innovative product in civil engineering field in India. In this paper discussed about the using ferrocement self-compacting concrete tanks is better than the conventional concrete tanks.

Survey Report

A survey on diminishing schemes for visible light communication

In the visible light communication in which data is superimposed on light, the communication range is visible. In pulse position modulation, for instance, when one image utilizes four openings, quad data can be sent by turning on just a single space among the four openings and killing the other three openings. In this strategy, the brightness becoming ¼ and feels not flicker but rather darker than when it is always on. Then again, when-when inverted pulse position modulation in which these openings of ON and OFF are switched is utilized, since one space is OFF, and three openings are ON, the brightness becomes 3/4, which does not turn out to be too dark. In this paper, we analyzed a crossbreed adjustment that can change the brilliance other than 1/4(25%) or 3/4(75%) by joining these pulse position modulation and reversed heartbeat position modulation. Visible Light Communication (VLC) utilizing light discharging diodes (LEDs) is an innovation that gives a chance to rapid minimal effort remote correspondence, being an option for successful and effective correspondence that can adapt to the real fast remote administrations request. This paper focuses around darkening mechanism that can be implemented in VLC frameworks to save energy and give exact illumination control. The inspiration behind this control mechanism, decrease and flow difficulties in down to earth usage, driver hardware, ongoing advancement, and future prospects are additionally concisely introduced.

Factors that cause delay in construction project- A critical review

The occurrence of a delay in the construction project is a common problem in civil engineering. The delay is defined as a situation where the actual progress of a construction project is slower than the planned schedule or late completion of the project. The problem of delay occurs during the life of the project leading to disputes and litigation. The delay will result in several negative effects like conflicts between owner, contractors and consulting, loss of productivity and exaggerated prices. This paper presents a major construction delay caused by rank order retrieved from past literature. The list of construction delay causes is collected and grouped together, are ranked. The result of this paper gives the major causes of delay.

Review Paper

A critical review on noise absorbing construction material from waste(s)

This study reveals the concept and applications of noise absorbing panels which is made from different materials both natural and artificial. As a part of green construction and to reduce waste from the coir industry which is located in and around Coimbatore in large numbers. A noise absorbing panel is designed and made from the coir with addition of polypropylene. The prepared sample is tested and the result is compared with other artificial made panels.

A coordinated control scheme of PSS and comparison of FACTS devices for improving power system stability

Nowadays, the continuous growth in power demand leads to expansion of the Power System network which makes existing system more sensitive and prone to instability. An important issue associated with the stability of a multi-area power system is low-frequency electromechanical oscillations from the multi-machine system. Generally, Power System Stabilizer (PSS) are used to compensate low-frequency electromechanical oscillation of interconnected Power System, but local PSS does not have global observance and controllability of inter-area low-frequency oscillation because of a control signal of local PSS and generated a local signal. So next resolution is Flexible AC Transmission System (FACTS) device with supplementary controller, that are used for effective damping of low-frequency electromechanical oscillations of interconnected Power System and to improve Power System stability. This paper presents Coordination control of PSS and FACTS Devices to damp out low-frequency electromechanical oscillation. In this research study, we use different FACTS Devices like Static VAR Compensator (SVC), Static Synchronous Series Compensator (SSSC), Static Synchronous Compensator (STATCOM), and Unified Power Flow Compensator (UPFC) to damp out low frequency electromechanical oscillation from a Multi-machine Power System and improve the stability of Interconnected Power System. Analyzing result of all FACTS devices on simulation, we found that UPFC gives a better response. Due to re-activeness, FACTS device like UPFC are considered and assessed for their damping controller design. In this research, we studied the implementation of supplementary Power Oscillation Damping (POD) Controller to control UPFC. POD Controller are designed to improve the dynamic performance of interconnected Power System under the transient condition to stabilize Power System. Some simulation results are carried out on Kundur Two area Four Machine systems under small disturbances. From simulation result, it reveals that the proposed controller damp-out low-frequency electromechanical oscillations effectively to improve Power System stability under small disturbance.
