Some cloud-based systems albeit internet-based systems suffer delays and disruptions in processing when in full use or large number of users are online. Sometimes the application may not readily respond to requests from the users (cf. denial of service – DOS) or some boxes may not present properly leading to the usual frustrations when it occurred. This lethargic behavior may be as a result of unavailability of facilitiesto carry the load. Such facilities like bandwidth and latency if not properly checked may lead to such disruptions of service. This paper therefore, tries to predict through testingby building a mathematical relations to predict the behavior of cloud-based systems during development and final production but before deployment, to gauge the behaviour of the system when an extreme number of usersare online and predict when the system is expected to demand additional resources. This paper was a result of original research for a higher degree conducted by the authors.

Now a days data mining techniques are rapidly growing in data science. There are many functions in data mining techniques (WEKA) and some of them are Gaussian process, Least Median Square, Linear Regression, Isotonic Regression, Pace regression, PLS Classifier, SMO regression, etc. In this paper we are fitting piece wise Isotonic Regression and Simple Regression models for Coastal Andhra Pradesh, Telangana and Rayalaseema regions for rainfall data from the year 1970 to 2017. We divide 1970 to 1989 as division I, 1990 to 2004 as division II and 2005 to 2017 as division III. Best model is chosen between isotonic regression and simple regression model using Root Mean Square Error criteria.

The asymptotic behavior of laminar forced convection in a circularduct, for a Herschel-Bulkley fluid with constantproperties, is analyzed by taking into account the viscous dissipation effects. The axial heat conduction in the fluid isneglected. The asymptotic temperature field and the asymptotic value of the Nusselt number are determined for every boundary condition that allows a fully developed region. Comparisons with other existing solutions for Newtonian and non-Newtonian cases are presented.

KEYWORDS: Asymptotic behavior, Herschel-Bulkley fluid, variable wall heat flux, laminar forced convection, viscous dissipation.

The most popular building material today is concrete. Concrete is used for buildings, industrial structures, bridges, railroad sleepers, roads, dams and more. Along with the development of concrete technology is increasingly developing and innovative so as to achieve better characteristics, cheaper prices and environmentally friendly. In the early days of the development of concrete......

Technology in the field of concrete construction continues to develop , this cannot be separated from the demands and needs of the community for increasingly advanced infrastructure facilities, such as bridges, dams that use high quality concrete. To achieve high-strength concrete requires special treatment of concrete. One of the concrete innovations that can be used is concrete with the reactive powder concrete (RPC) method. Reactive powder concrete ( RPC) is a concrete innovation that has a high compressive strength of up to 800 N/mm2 or 800 MPa........

The aim of this paper is presenting the planning design of a power network which supply the power from a vicinity Distribution Network Operator (DNO) 132KV overhead line through one underground cable terminated to one of the 132KV lattice towers to an industrial state. (It should be mentioned that feeding this high-profile industrial state by one underground cable does not comply firm capacity). The design starts from 132/11KV substation and continues to entire 11KV network up to each factory containing the 400V main circuit breaker on the LV side of the transformer. It is possible to describe the planning process of an electrical network in several stages.

KEYWORDS: Distribution Network Operator, Overhead line design, Circuit breaker and Transformer.

This study provides a description of a system designed as a new progressive method of measuring and evaluating geometric parameters of surfaces using laser profilometry. The study focuses on a more detailed description of the behavior of these individual parts functioning in mutual interaction as a whole. A method of measuring samples using the triangulation principle is described. The study also measured problematic types of surfaces, such as glossy surfaces, where the use of specific or non-traditional methods of treating these surfaces is partially avoided. The measured and evaluated sample was also created by a progressive technology of material separation using a laser. In the end, the study focuses on the evaluation of the measured profile data of the examined surface

In this paper, we investigate an inventory model with non-instantaneous deteriorating items, stock-dependent demand, partial backlog shortages, and trade credit. Some factors, like as trade credit and inflation, are introduced in this model. The demand rate is a linear function of time and the model has non-instantaneous deterioration that is time dependent. Demand and perhaps deterioration alter inventory levels over a cycle. This study demonstrates that the overall average is maximal when the total trade credit period is shorter than the whole cycle length. To explain the development model, a numerical example is used. The ideal solution is also subjected to a sensitivity analysis in terms of important parameters.
