As we know radium cutting through PC is readily available from that, we got the idea of our project i.e. "Low cost, thermocol cutter". In this project the microcontroller is the backbone of the hardware circuitry. All the controlling actions are done by the micro controller. A hot rod basically the soldering gun is used for cutting purpose. Here, the thermocol is not actually cut, but it is melted at a specified temperature with the help of soldering gun. So this project is used for cutting different figures and shapes as per the program of the micro controller. Optocouplers are used to provide isolation between the micro controller and the hardware circuitry. Stepper motors are used for controlling the different directions of different axis. Thickness of the thermocol will depend upon the length of the cutter and its heating capacity. Alphabets and numerical are generally cut using this project but figures of all shapes and sizes can be cut up to the limit of the work platform.

The adopted strategy to overcome the housing shortage crisis in Iran is the mass production. The way forward to accelerate the mass production, is adopting the industrial building systems with the increased prefabrication. One of the most optimal new building systems is Lightweight Steel Framing (LSF) Technology. Parand Residential Complex as the first serious project to industrialize the construction processes in Iran is facing the various problems during the processes of manufacture and execution of LSF components. The research is to offer an optimized model for the manufacture and execution processes of LSF Technology in the constructive projects. So, the manufacture and execution processes of LSF Technology in the research case-study were taken into consideration to recognize the existing advantages and disadvantages. Finally, offering four strategies to compensate the deficiencies and three strategies to intensify the strengths, a model to coordinate these two processes presented.

We describe various misconceptions and misinterpretations concerning presentation of the hysteresis loop for ferromagnets occurring in undergraduate and college textbooks. These problems originate from our teaching a Theoretical solid state / condensed matter physics (TSSP/CMP) course. A closer look at the definition of “coercivity” reveals two distinct notions referred to as the hysteresis loop: B vs. H or M vs. H, which can be easily confused and, in fact, are confused in several textbooks. The properties of the M vs. H type hysteresis loop are often ascribed to the B vs. H type loops, giving rise to various misconceptions. An extensive survey of textbooks at first in the TSSP/CMP area and later extended into the areas of general physics, materials science and magnetism / electromagnetism has been carried out. Relevant encyclopedias and physics dictionaries have also been consulted. The survey has revealed various other substantial misconceptions and/or misinterpretations than those originally identified in the TSSP/CMP area. The results are presented here to help in clarifying the misconceptions and misinterpretations in question. The physics education aspects arising from the textbook survey are also discussed. Additionally, analysis of the CMP examination results concerning questions pertinent to the hysteresis loop is provided.

The magnetic response of transverse wave propagation of double layered nanoplate embedded in an elastic medium is studied employing nonlocal continuum theory. The displacement equation of nanoplate with magnetic and elastic medium is devised with the help of Lorentz force and Winkler elastic foundation. The frequency equations are acquired for nanoplate with simply supported edges. The numerical result reveals that the magnetic strength and elastic medium increases the frequencies of double layered nanoplates. The perfection of the present frequency value is noted by comparing it with the existing literature.

Pakistan is among the top ten countries in the world with large area under citrus orchards. Punjab province is endowed with one of the best Kinnow varieties of the world and Sargodha district has largest share in area and production. The primary data was collected from two tehsils (revenue units) of Sargodha district, namely Sargodha and Bhalwal. The Value Chain Analysis was performed to investigate the marketing inefficiency of Mandarin trade. The study concluded that by decreasing the number of the intermediaries in both form i.e. open and packed, not only the purchased price of the consumer decreased but also producer received high profit.

The Line graph L(G) of an undirected graph G is another graph L(G) that represents the find adjacencies between the edges of G. In this paper, we find the Maximum and Minimum of total coloring for a certain Line graphs of a snake graph families and further we established the results on maximum number colors required to total coloring to the graph G is denoted by and similarly we color the vertex of a snake graph and obtained certain results and denoted by X_Max^(G)

The difficulty of calculating transient heat transfer in foamed concrete panel is complex due to its porous and multi-phase material nature. This paper reports the basis of one-dimensional Finite Difference method to acquire thermal properties of foamed concrete. Additionally, this paper also incorporates the execution of the method and the validation of thermal properties model of foamed concrete. A one-dimensional finite difference heat conduction programme has been developed to predict the temperature development through the thickness of the foamed concrete slab, based on an initial estimate of the thermal conductivity-temperature relationship as a function of porosity and radiation within the voids. The accuracy of the model was evaluated by comparing predicted and experimental temperature profiles obtained from small scale heat transfer test on foamed concrete slabs, so that the temperature history of the specimen calculated by the programme closely matches those recorded during the experiment.

Decision making method of telecommunications channel throughput distribution based on linear programming and neuro fuzzy predicting tool.

In this paper, various generalized imputation procedures have been suggested and their corresponding families of estimators of population mean have been considered. Asymptotic expressions for biases and mean squared errors have been obtained. Optimum conditions are investigated at which the proposed family of estimators has minimum mean squared errors. It has been shown that the proposed imputation procedures and the resulting families of estimators due to Singh and Horn (2000), Ahmed et al. (2006), Shukla and Thakur (2008) and Pandey et al (2015) are members of the suggested procedures and estimators. The results of this paper are general and of immense useful.
