Effect of Wind Load on Structural Performance of Dimensionally Regular & Irre...Dr. Amarjeet Singh
Outriggers system is used as one of the best way of increasing the lateral stiffness and has been generally utilized in tall building structures. The outrigger system is very effective in increasing structure’s flexural stiffness. It is likewise viable in decreasing the horizontal top deflection and bending moments in the core of high-rise frame-core structures. This study presents the detailed analysis on how the top drift, inter-story drift, base moment in the core are influenced by the outriggers stiffness, outriggers optimum locations, columns axial stiffness and foundations flexibility. outrigger braced structures can strengthen a structure without disturbing its aesthetic appearance and this is a significant advantage over other lateral load resisting systems. The thesis compare between many outriggers systems including both concrete & steel Outriggers. The Rectangular shape & L- shaped building structures are taken for analysis. The study also presents simplified procedure to optimize the location of the outriggers that will result in a maximum reduction in the lateral displacement at the top of the building. The modeling of the structure is done using “ETABS” program. The investigation of the model is completed by comparable static technique. Finally, the thesis proposed a simplified analysis for outriggers structures with core for both regular and irregular high rise building.

The main aim of this paper is to identify the type of bracing for the better seismic
performance of the structure by building steel bracings at different floor
levels.Duringearthquakes the human loss is mainly due to the failure of structures.
Seismic deficitstructures will crumble even at low magnitude earthquakes.Many
existing structures need to be retrofitted,installation of steel bracing for existing
structure will be easiest way instead of buildingshear walls.Steel tubular X-bracing
system have been installed to the strcuture at different floor levels for choosen G+5
RCC building and analyzed by Non-linear static push over analysis.Six cases are
considered in this study, in each case the placement of bracing were changed to find
out the better performane of the structue with variation in the placement of bracings at
different storey levels.The comparisions made between these six cases by keeping base
model as ideal model along with the parameters like base shear,displacement and
inter-storey drift.After comparing it was found that there is a significant increase of
Base Shear by 14.90%,16.53% for case-3,case-5 models respectively when compared
with basemodel i.e. case-1with out bracing. The displacement is reduced by 17.39%,
17.39% for case-3 and case-5models respectively when compared with base model.
There is a reduction of inter-storey drift by 33.33%, 33.33% for case-3 and case-5
models respectively when compared with base model. Case-3 and case-5 braced
frames has been significantly performed well with the reduction in storey drifts and
displacements and increase in base shear
Evaluation of Flat Slab by Varying Percentage of Infill Wall in RC Building U...ijtsrd
In the area of high seismicity the conventional slabs are become uneconomical due increase in design requirement to tackle additional seismic loads. The use of deep beams, increased column sections etc led to costly frame work. Moreover masonry infill wall effect is not incorporated in the design of conventional slab building frames, which led to unsafe or uneconomical design. These panels are used to fill gaps between the frames of building. Under seismic action these walls increases the strength and stiffness and reduces the time period by increasing the seismic mass of the building. This hinders the ductility requirement of the conventional frames which may lead to brittle failure under seismic action. To avoid this effect the flat slab systems are used. The flat slabs are the beamless frame having lower lateral stiffness, high storey drift, and are more flexible. But these are more susceptible to failure under seismic action.Hence to avoid the failure of flat slab structure under seismic action, some lateral resistance structural elements are used in order to increase stiffness, reduce storey drift, lateral displacement thereby improving the lateral resistance of the system.In the present study an attempt is made to analyze and study the various multi storied reinforced concrete flat slab building frames with several percentage of infill wall considering the lateral resistance of flat slabs by evaluating parameters, subjected to seismic loading. A number of flat slab building frames are analyzed by varying the percentage of infill wall 0 , 50 , 80 and 100 to evaluate parameters affected by the addition of infill wall in the flat slab. The results obtained by analysis are used to study and compare the effects of variable percentages of infill wall on the lateral resistance of flat slabs by varying storey height. The several parameters are compared for the lateral resistance assessment of flat slabs. The effect of masonry infill wall on flat slab frame in studied in terms of several parameters for the lateral resistance of the flat slab under seismic actions.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
