Abstract:

In the present investigation the distribution of mean velocity are experimentally studied on square cross section Double-S duct.The experimental set up Double-S duct having center line length of 750 mm and square cross section of (100×100) made up of transparent Perspex sheet to study flow visualization. Experiment is carried out at mass averaged mean velocity 40 m/s. The velocity distribution shows the Bulk of flow shifting from inner wall to outer wall in the first bend and third bend of the duct and outer wall to inner wall in the second bend and forth bend of the duct along the flow passage is very instinct. Flow at end of the duct is purely uniform in nature due to non existence of secondary motion. The experimental results then were numerically validated with the help of Fluent, which shows a good agreement between the experimental and predicted results.

Abstract:

The maintenance of bridges as a key element in transportation infrastructure has become a major concern due to increasing traffic volumes, deterioration of existing bridges and well-publicized bridge failures. Therefore, bridge maintenance planning should accommodate multiple performance goals that need to be quantified by various performance indicators. The main goal of this research is to develop a decision support model for maintenance of bridges in Egypt within acceptable limits of safety, serviceability and sustainability. The General Authority for Roads, Bridges, and Land Transport (GARBLT) was chosen for the study of the current research as it represents the biggest governmental organization responsible for planning, operating and maintaining of bridges in........

Abstract:

The relationship between architecture and climate is always a hotspot, interesting in the recent architecture studies, especially in corelation with thermal comfort in equatorial tropic climate, such as Indonesia vernacular dwellings. Such researchs has shown the principle of climate-oriented architecture, focus on qualitative description of passive design in getting thermal comfort. The result, it is difficult to evaluate accurately thermal performance of the vernacular buildings by qualitative approach, therefore some incorrect conclusions are easily to be drawn in general result, also incorrectly. A detailed field, empirical study of Baduy Jero‟s vernacular dwellings at Kanekes village, Lebak regency, Banten Province, Indonesia, has been done in the four seasons of 2015.......

Abstract:

Speaker recognition is related to speaker identification and speaker verification problems. Speaker identification is a task to identify the provided speech sample (utterance) as belonging to one speaker from the set of known speakers (1:N match). Speaker verification is a task of comparison of the utterance to one given speaker identity and either accepting or rejecting the identity (1:1 match).Here we are using an artificial intelligent (AI) based technique to complete this task. Here we are trying to differentiate the sound of APJ Abdul Kalam sir and the Donald Trumph president of America. Herewe are using K-nearest neighbor (KNN) algorithm which is a powerful supervised learning tool. We have extract the four parameters of sound and these are 'power spectral density', "spectral centroid‟, "spectral flatness‟ and "roll-off frequency'.

Abstract:

This work aims to analyze the feasibility of using PLC – Power Line Communication technology in local networks in comparison with UTP twisted pair metallic cable. The study covers PLC technology for indoor access. In the run of the research is a brief introduction on the PLC and on the technology of data transmission through metal cables of twisted pair UTP, telling a little of its history, operating principles, categories and types of existing cables. The focus of the research is to analyze the feasibility of using PLC technology in local networks where the passage of metallic twisted pair cables is not possible or feasible due to existing physical barriers and among others, as for example pipelines for The passage of the crowded cables or distance between the parties to be intertwined. For this conclusion, a case study was carried out on a laboratory bench analyzing and comparing the two technologies through the HTTP, full page HTTP, ping for Gateway, RDP and speed tests. According to the research, PLC technology is shown to be effective, and it is concluded that it is feasible to use PLC in local networks.

Abstract:

Major requirement of the next generation wireless communication systems is to provide higher data rates in transmission of signal in order to meet higher demand of quality services. Multi-User Detection is a field which comprises all aspects related to the detection of mutual users whose received signals are not orthogonal to each other. This generally corresponds to (non orthogonal) CDMA systems, because these systems have a large number of users whose signals overlap in frequency and time. DS-CDMA system is extensively used wireless communication technology. Use of Direct Sequence Spread Spectrum causes MAI (Multiple Access Interference) which in turn affects performance of DS-CDMA system. To distinguish user data in presence of Multiple Access Interference, various Multi-User detection techniques were suggested by different researchers. Objective of this paper.....

Abstract:

k-means algorithms are one of the most applied algorithm due to its simplicity and efficiency, k-means algorithm performance are generally good but also has got some limitation, it takes initial cluster centre as an arbitrary data points, number of cluster are given by the user, missing data problem, inefficient with the large data set, various research work has been done to improve efficiency of the k-means algorithms. Our main work to deal with the initial cluster centre problem various research work has been done in this direction but still there is not any global method of the initializing the initial cluster centre or mean of the k-means algorithms, in our work we generate the initial cluster centre by using the idea of M-way tree, this method is efficient as compare to the traditional k-means algorithms.

Abstract:

As the use of internet is increasing the corporate migrating their business from traditional computing to the cloud computing and thus no of user is increasing on cloud & load is also increasing. Thus to provide congestion free and reliable on demand service to client load balancing method is needed. Many algorithms is proposed for load balancing & auto scaling to handle the load .we can use cloud service to make load efficient model in cloud environment. This load efficient model will provide the load balancing, scaling capabilities and monitoring of solutions in the cloud environment.To achieve the above mentioned, we use public cloud services such as amazon's EC2, ELB. This research is divided into four parts such as load balancing, auto-scaling, latency based routing, resource monitoring. We will implement the individual service and test while providing load from external software tool Putty and we will produce the result for efficient load balancing.
