The building of networks and the establishment of communication protocols have led to distributed systems, in which computers that are linked in a network cooperate on a task. The task is divided by the master node into small parts (sub problems) and is given to the nodes of the distributed system to solve, which gives better performance in time complexity to solve the problem compared to the time required to solve the problem in a single machine. Load balancing is the process of redistributing the work load among nodes of the distributed system to improve both resource utilization and job response time while also avoiding a situation where some nodes are heavily loaded while others are idle or doing little work. So before sending these parts of problem by the master to the nodes, master node should know the actual work load of all the nodes. We try a dynamic approach to find out the work load of each participating nodes in the distributed system by the master before sending the parts of the problem to the nodes.
This paper describes an algorithm which runs in the master machine and collects information from the nodes of the distributed system (client server application) and calculates the current work load of the nodes of the distributed system. The algorithm is developed in such a way that it can calculate the loads of the nodes dynamically. This means the loads can be evaluated if new nodes are added or deleted or during current performance of the nodes. The whole system is implemented on linux machine and local area network.

An Adaptive Load Sharing Algorithm for Heterogeneous Distributed SystemIJORCS
Due to the restriction of designing faster and faster computers, one has to find the ways to maximize the performance of the available hardware. A distributed system consists of several autonomous nodes, where some nodes are busy with processing, while some nodes are idle without any processing. To make better utilization of the hardware, the tasks or load of the overloaded node will be sent to the under loaded node that has less processing weight to minimize the response time of the tasks. Load balancing is a tool used effectively for balancing the load among the systems. Dynamic load balancing takes into account of the current system state for migration of the tasks from heavily loaded nodes to the lightly loaded nodes. In this paper, we devised an adaptive load-sharing algorithm to balance the load by taking into consideration of connectivity among the nodes, processing capacity of each node and link capacity.
A study on dynamic load balancing in grid environmentIJSRD
Grid computing is a collection of computer resources from multiple locations to reach a common goal. Grid computing distinguishes from conventional high performance computing systems that are heterogeneous and geographically dispersed than cluster computer. One of the major issues in grid computing is load balancing. Classification of load balancing is: Static – Dynamic, Centralized – Decentralized, Homogeneous – Heterogeneous. Techniques like: Ant Colony Optimization, Threshold based and Optimal Heterogeneous are used by some researcher to balance the load. This survey paper discusses set of parameters to be used for comparing performance of each of them. In addition to that it says which technique is more useful for grid environment.

Life cycle cost analysis of overlay for an urban road in bangaloreeSAT Journals
Abstract
Pavements are subjected to severe condition of stresses and weathering effects from the day they are constructed and opened to traffic
mainly due to its fatigue behavior and environmental effects. Therefore, pavement rehabilitation is one of the most important
components of entire road systems. This paper highlights the design of concrete pavement with added mono fibers like polypropylene,
steel and hybrid fibres for a widened portion of existing concrete pavement and various overlay alternatives for an existing
bituminous pavement in an urban road in Bangalore. Along with this, Life cycle cost analyses at these sections are done by Net
Present Value (NPV) method to identify the most feasible option. The results show that though the initial cost of construction of
concrete overlay is high, over a period of time it prove to be better than the bituminous overlay considering the whole life cycle cost.
The economic analysis also indicates that, out of the three fibre options, hybrid reinforced concrete would be economical without
compromising the performance of the pavement.
Keywords: - Fatigue, Life cycle cost analysis, Net Present Value method, Overlay, Rehabilitation

Survey on Load Rebalancing for Distributed File System in CloudAM Publications
Distributed file system is used as a key building block of cloud computing. In distributed file system, a
large file is divided into number of chunks and allocates each chunk to separate node to perform MapReduce function
parallel over each node. In cloud, if number of storage nodes, number of files and assesses to that file increases then
the central node (master in MapReduce) becomes bottleneck. The load rebalancing task is used to eliminate the load
on central node. Using load rebalancing algorithm the load of nodes is balanced as well as the movement cost is
reduced. In this survey paper the problem of load imbalancing is overcome.
Efficient Resource Allocation to Virtual Machine in Cloud Computing Using an ...ijceronline
The focus of the paper is to generate an advance algorithm of resource allocation and load balancing that can deduced and avoid the dead lock while allocating the processes to virtual machine. In VM while processes are allocate they executes in queue , the first process get resources , other remains in waiting state .As rest of VM remains idle . To utilize the resources, we have analyze the algorithm with the help of First-Come, First-Served (FCFS) Scheduling, Shortest-Job-First (SJR) Scheduling, Priority Scheduling, Round Robin (RR) and CloudSIM Simulator.
Cloud computing is the set of distributed computing nodes. It is the use of computing resources that are delivered as a service over a network. Virtualization plays a crucial role in cloud computing. Typically VMs are offered in different types, each type have its own characteristics which includes number of CPU cores, amount of main memory, etc. and cost. Presently, static algorithms are being used for scheduling VM instances in cloud. Instead of these, an algorithm is proposed here which dynamically detects the load and then schedules the tasks. The main purpose of the proposed scheduling strategy is to find the minimally loaded computational node. Upon receiving task requests from the clients, server has to schedule these to a minimally loaded node among all available computing nodes.

Hybrid Scheduling Algorithm for Efficient Load Balancing In Cloud ComputingEswar Publications
In cloud computing environment, various users send requests for the transmission of data for different demands. The access to different number of users increase load on the cloud servers. Due to this, the cloud server does not provide best efficiency. To provide best efficiency, load has to be balanced. The highlight of this work is the division of different jobs into tasks. The job dependency checking is done on the basis of directed acyclic graph. The dependency checking the make span has to be created on the basis of first come first serve and priority based scheduling algorithms. In this paper, each scheduling algorithm has been implemented sequentially and the hybrid algorithm (round robin and priority based) has also been compared with other scheduling algorithms.

Tremendous usage of internet has made huge data on the network, without compromising on the
performance of network the end-users must obtain best service. As cloud provides different services on
leasing basis many companies are migrating from their own Infrastructure to cloud,This migration should
not compromise on performance of the cloud, The performance of the cloud can be improved by having
excellent load balancing strategy such that the end user is satisfied. The paper reveals the method by which
a cloud can be partitioned and a study of different algorithm with comparative study to balance the
dynamic load. The comparative study between Ant Colony and Honey Bee algorithm gives the result which
algorithm is optimal in normal load condition also the simplest round robin algorithm is applied when the
partition are in Idle state

A New Function-based Framework for Classification and Evaluation of Mutual Ex...CSCJournals
This paper presents a new function-based framework for mutual exclusion algorithms in distributed systems. In the traditional classification mutual exclusion algorithms were divided in to two groups: Token-based and Permission-based. Recently, some new algorithms are proposed in order to increase fault tolerance, minimize message complexity and decrease synchronization delay. Although the studies in this field up to now can compare and evaluate the algorithms, this paper takes a step further and proposes a new function-based framework as a brief introduction to the algorithms in the four groups as follows: Token-based, Permission-based, Hybrid and K-mutual exclusion. In addition, because of being dispersal and obscure performance criteria, introduces four parameters which can be used to compare various distributed mutual exclusion algorithms such as message complexity, synchronization delay, decision theory and nodes configuration. Hope the proposed framework provides a suitable context for technical and clear evaluation of existing and future methods.

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.
