Diversity Indices of Aquatic Macrophytes in Jharokh Wetland, Assam, India
The present study was conducted for a quantitative investigation of macrophytes of the Jharokh wetland of the Gorjaan wetland system of Hajo area of Kamrup district of Assam , during March 2015 to February 2016. During the investigation, 140 different species of macrophytes were recorded in pre monsoon and 60 species in winter from the wetland.While the number of free floating, rooted floating leaved and submerged species are almost same in both the seasons of the wetland, the number of emergent species vary in both the two seasons i.e 80 in pre monsoon and 38 in winter in the wetland respectively.Based on Importance Value Index (IVI) Eicchornia crassipes (Mart.) Solms, Eurayle ferox Salisb, Ludwigia adscendes (L.) H.Hara, Hygroryza aristata (L.f.) Royle,Cyanodon dactylon and Hymenachne acutigluma (Steud) Gill, Leersia hexandra L. , Lemna minor, Ipomea carnea var.fistulosa were dominant species in pre monsoon whereas Eicchornia crassipes (Mart.) Solms , Ruppia maritima, Myrophullum alterniflorum,Chara vulgaris,Ceratophyllum demesrsum (L.),Nelumbo nucifera Gaertn, Nymphaea nouchalli Burm.f.,Nymphoides indicum (L.) were dominant in winter.

Recent Progress in Dye Sensitized Solar Cells
The article summarizes the recent trends in solar cells particularly in the field of Dye Sensitized Solar Cell. The DSSC we would refer for short for Dye Sensitized Solar Cell. The Dye Sensitized Solar Cell are the recent trend in the field of solar photo voltaic electricity generation. The Solar Cells captures the solar radiation and he photovoltaic material convert those solar radiations to the usable voltage which could be used for various purpose. The conventional method using in this regard consists of use of Silicon wafer photovoltaic solar cell which are way too costly to be used. The most efficient way to achieve the objective (cheaper solar energy) is to replace the Silicon from the PV Solar Module (Silicon being the most costly material of the module) with any other chemical or element which is abundantly available in nature and also is very cost effective. Titanium Dioxide (Ti02) is one major compound which can be used to replace Silicon along with the Ruthenium Dye. Apart of presently being many methods for generation or harnessing Solar energy, the Dye Sensitized Solar Cells or DSSCs have acquired the attention of much more wider section of scientists and engineers working in this field. Due to its greater and wider working capability in the solar UV Spectrum ad future scope of the material and porous structure and semiconducting behaviour the mesoporous tiatania made Dye Sensitized Solar Cells are widely expected to be used in innovative applications.

Novel Approach for Residential Grid Connected Solar Photovoltaic System Using Matlab Simulink
The need for energy is never ending. This is certainly true of electrical energy, which is a large part of total global energy consumption. But growing in tandem with energy needs are the concerns about sustainable development and environmental issues, such as the movement to reduce greenhouse gas emissions. The fossil fuels and nuclear fuels are not renewable and reserves of these fuels will run out some day in the future. The exploitation of solar energy has become an essential measure to address present energy shortages and environmental problems. We have several reasons to be optimistic as there is great excitement about the possibilities opening up before scientific community in the field of solar PV. Therefore today our main focus is to develop renewable energy especially from solar. Government of India also promoting solar energy and also providing subsidy to peoples so that pollution level means CO2 emission level decreased. In our research work photo crystalline PV solar panel is used and with help of boost converter DC level increased and this is achieved by MPPT also used PI controller to limit voltage and current. Our main focus is to reduce THD level under 5% as per IEEE standards. Our THD is below the level of IEEE standard

Scaling of Ground motions for performing Incremental Dynamic Analysis of RC framed structures
In the modern world of structural engineering design of structures subjected to earthquake promotes a need of developing simple and practical methods for estimating seismic demands of structures. These methods are based on their behavior which is to be predicted prior to design. Researchers are implementing various static as well as dynamic, linear as well as nonlinear to predict the performance of the structure. This study aims towards performing incremental dynamic analysis of structures using SAP 2000 subjected to several scaled ground motions scaled using SEISMOMATCH 2016. This procedure is followed by the pushover curves plotted for each structural model. The 5, 12 and 18 story moment resisting RC frames are used for study which is located in the highly active seismic region of north India. Due to improper knowledge of seismic hazards buildings designed using modern principles observe earlier failure. This leads to loss of property as well as lives.

Evaluating Seismic Efficiency of Combination of Bracing for Steel Building
Steel structures played an important role in the construction industry.It providing strength, stability, and ductility. A study regarding the seismic response of steel structures is necessary. In the present study, modeling of the steel braced structures with a different combination of bracing and analyses structure using commercially available SAP2000 software. A bracing element in the structural system plays a vital role in structural behavior during an earthquake. In this study there are four types of braces are used. Such as X bracing, V bracing, inverted V bracing, and knee bracing. The combinations from these bracing are X and V type bracing, X and inverted V type bracing, X and Knee type bracing, V and inverted V type bracing, V and Knee type bracing, Knee and inverted V type bracing. Response spectrum method is used for seismic analysis. Comparison between the seismic parameters such as base shear, roof displacement, story drift, for steel frame with different combination of bracing are studied

Wind Excitation Control in Skyscraper
In skyscraper structure vibration produces because of wind intensity. This wind intensity transferred into dynamic load which cause the structure and along its connected portion structure create problem. The type of high rise structure mass create huge problem in the height increases, but the modified shape as well as some passive energy control system reducing lateral load on the structure. The effect modified shape of structure with great height analyses for along, across direction and twisting of structure in Etab. Base on the analysis results, it has been concluded that effect of tune mass damper intermediate stories play significant role to decreases the natural frequency and lateral displacement in skyscraper.
