Abstract: The world is experiencing rapid and tremendous growth in computer communication network technology. This technology provides the technical infrastructure, where routing protocols are used to transmit packets across the Internet. Routing protocols specify how routers communicate with each other by spreading information. Enhanced Interior Gateway Routing Protocol (EIGRP) is one of the hybrid protocols, which is based on Interior Gateway Routing Protocol (IGRP). In our work titled “Improved Shortest Path First Algorithm for Enhanced Interior Gateway Routing Protocol (EIGRP)”, we proposed an improved shortest path first algorithm (ISPFA) used in enhanced interior gateway routing protocol. This work addressed the end-to-end delay problem associated with the existing routing protocol. In this paper, we carried our comprehensive analysis of the proposed protocol and assessed its comparative performance with existing protocol. The analysis shows average improvement of 36% by the proposed protocol over the existing.

Abstract: Building Information Modeling (BIM) also accustomed as virtual model technology is a process or technique implicating the propagation and administration of programmed embodiment of physical and utilitarian aspects of places. It is an avant-garde development that is rapidly transforming the Architecture-Construction-Engineering (ACE) industry. This work addresses the status of Building Information Models and the environment necessary for them to develop into more broadly used process including modularization and cost assessment. BIM helps project internal stakeholders to envisage what is to be built in a virtual environment and to ascertain any latent design, construction or outfitted issues. The paper presents an outline of BIM with center on its nucleus concepts, challenges, and applications in the all stages of project life-cycle and managerial issues among project stakeholders. The paper also depicts the role of government for the enlargement of BIM technology especially in India. Further, the paper concludes that comprehensive implementation of this technology by the ACE industry will acquire little more years.

Abstract: In this paper, it’s reviewed the concept and methods of measuring productivity construction and the most important factors affecting on productivity. In addition, the most important applications of techniques (Multiple Linear Regression (MLR), Artificial Neural Network (ANN), and support vector machine techniques (SVM)) in the construction productivity field. Most of the previous studies are interested in identifying the factors affecting the construction productivity so as to achieve control and improve construction productivity and find a mathematical model to estimation construction productivity. Use several techniques to analyze the data of which was used to Identify factors affecting such as (relative importance, quantitative engineering project scope definition, Severity index, sensitivity analysis), and to use them for the development of predictive models such as (Linear Regression, Fuzzy models, Support Vector Machine and Artificial Neural Network).

Abstract: The performance and service life of the plunger and seal of fracturing pumps directly affect the implementation of fracturing technology. The structure characteristics of the plunger seal pair in OPI-1800AWS fracturing pump are analyzed. This paper focus on the contact stress between the plunger and the sealing ring, and the effect of the sealing ring structure parameters on the contact stress is analyzed, and the structure of the sealing ring is optimized. The failure and leakage reason of the plunger seal pair is analyzed. A new structural renovation plan for the plunger seal pair in fracturing pumps is put forward, that is, the sealing effect and service life of the plunger and seal can be increased by strengthening the plunger surface, selecting excellent sealing materials, improving the structure of the sealing ring, adding scraping ring, keeping the moving track of the plunger and the axis of the cylinder jacket in line.
