Multi-channel analysis of Surface Wave (MASW) profiling for delineation of sub surface stratigraphy at various locations within and surrounded Kolkata High Court
This document summarizes a study that used Multi-channel Analysis of Surface Waves (MASW) profiling to delineate subsurface stratigraphy around the Kolkata High Court building in India. MASW data was collected along 6 profiles near the building to determine shear wave velocity with depth. The data showed that within 15 meters of the surface, shear wave velocities were low (<200 m/s), indicating soft soil that could cause settlement. Below 15 meters, velocities increased, indicating denser soil. This helps explain cracking observed in the heritage building, likely due to soft near-surface soil conditions. The study classified the near-surface soils as NEHRP Site Class F and deeper soils as Class E, providing information on
DUAL-CHANNEL MODEL FOR SHALLOW WATER DEPTH RETRIEVAL FROM WORLDVIEW-3 IMAGERY...Luhur Moekti Prayogo
This research aims to estimate shallow water depth using Worldview 3 satellite imagery and dual-channel models in Karimunjawa waters, Central Java – Indonesia. To build dual-channel models, we used spectral data that had been validated in the field. Twenty-three depth data were recorded synchronous to the spectral data used in forming the semianalytical dual-channel models. Twelve models were tested using 633 depth data with a non-linear model using multiple polynomial regression analysis degrees 1 and 2. This research has shown that the proposed model has been confirmed to improve depth accuracy. Models using blue and green channels of Worldview 3 image result in good accuracies especially for estimating depths with interval from 5 to 20 meters with RMSE of 1,592 meters (5–10 meters), 2,099 meters (10–15 meters), and 1,239 meters (15–20 meters). The wavelengths of two channels have a low absorption rate to penetrate deeper waters than other wavelengths. The research also finds out that there are still models that meet the IHO standard criteria.

The influence of tree induce suction on soil suction profileseSAT Journals
Abstract This study provided an investigation of active root tree zone located at the toe of the slope. This section of slope generated suction due to tree water uptake during dry season. A field monitoring set up program was carried out to collect matric suction data at slope with absent of a tree and with a tree located at toe of the slope. The installations of Jet-fill tensiometer and Gypsum blocks to measured matric suction were placed at vicinity of tree with certain depths and distances. The distribution in matric suction values and matric suction profiles responses to tree water uptake and rainfall were investigated. The decreased of soil matric suction after intense rainfall in this monitoring period as a function of an initial condition before the water uptake driven by active root tree substantially increased matric suction (low moisture content). Matric suction significantly increased at vicinity of tree trunk located at toe of slope compared to the slope without tree. This exploration provides the viewed of mature tree can significantly alter the suction distribution driven by transpiration in an unsaturated soil slope. It takes consideration by preserved mature tree can improved soil properties in geotechnical slope design. Index Terms: active root zone, tree water uptake, field monitoring, unsaturated soil, matric suction

Determination of Local Site Effects in Taikkyi Area, Yangon Region by using M...ijtsrd
Considering the possible local site effect is one of the most important facts in seismic hazard assessment. Depending on the local site condition, the characteristics of the seismic waves propagated through different geological layers and amplified the surface ground motion. In this study, one of the geophysical method of microtremor observations were carried out at 112 sites throughout the Taikkyi area. After analyzing the recorded microtremor observed data by Cygwin Software, we determined the horizontal to vertical spectral ratio HVRs that reflects the local site effects of the study area. The main outcomes of this research is to develop the fundamental frequency map and peak amplitude or soil amplification map of Taikkyi area. According to the evaluation results, the fundamental frequency is ranging from 1 to 2.3 Hz and most parts of Taikkyi area show in the range of 1.3 to 1.6 Hz. The peak amplitude of HVRs potential soil amplification is ranging from 1.5 to 3.6 and most parts of the area are in the range of 1.5 to 2.5.

Remote Sensing Method for Flood Management SystemIJMREMJournal
Flood occurred when heavy and continuous rainfall exceeding the absorptive capacity of soil and the flow
capacity of rivers, streams, and coastal areas. Land areas that are most subjected to floods are areas situated
adjacent to rivers and streams, that are known as floodplain and therefore considered as “flood-prone”. These
areas are hazardous to development activities if the vulnerability of those activities exceeds an acceptable level.
The main objectives of this study are; to identify floodplains and other susceptible areas, and to assess the
extent of disaster impact in the study area which is located at Kota Tinggi, Johor, Malaysia. This area
experienced an unprecedented flood during December of 2006 to January of 2007.Questions such as how often
and how long the floodplain will be covered by water, and at what time of year flooding can be expected need to
be answered. Thus, an understanding of the dynamic nature of floodplains is greatly required. Multi-temporal
Radarsat-1images, Landsat ETM+ image, topographical maps and land use maps were used in this study for
the purpose of delineating the flood extend before, during and after the flood event. DEM acquired from
topographic map is used to derive flood depth. The final outputs of this study are flood extent and flood depth
maps where both of these maps show the impact of the flood to environment, lives and properties. This map is
also important and can be applied to develop a comprehensive relief effort immediately after flooding.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
