Thermal Performance of Three Sided Artificially Roughened Double Duct Parallel Flow Solar Air Heater - A CFD Approach
No full textA sun powered air warmer is essentially a warmth exchanger, which blocks the occurrence sun based radiation changes over it into warm lastly exchanges this warmth to a working liquid for an end utilize system.The method of air streaming in the channels of a sun powered air radiator is a standout amongst the most critical angles worried about sun oriented air radiator which predominantly influence. A twofold pipe parallel stream falsely roughened sun powered air radiator with three sides of the safeguard plate is examined in the present examination. Dissimilar to the ordinary model of sun powered air warmer with just a single sided roughened safeguard plate, a novel sun based air radiator with three misleadingly roughened safeguard plate is utilized so the surface zone of the safeguard plate is expanded which at last builds the rate of warmth exchange. Also, a twofold channel parallel stream game plan through internal and external conduit of sunlight based air warmer is considered request to improve the warmth exchange rate. A numerical examination of the warmth exchange and erosion factor qualities of a twofold pipe parallel stream three sided misleadingly roughened sunlight based air warmer has been completed. A business limited volume CFD code ANSYS FLUENT is utilized to mimic turbulent wind stream through counterfeit roughened sunlight based air radiator. Overseeing conditions of the liquid stream and warmth exchange i.e. Navier-Stokes condition and vitality condition are settled with RNG k-ε turbulence demonstrate. Nine distinctive design of square rib are considered with relative harshness pitch (P/e = 5-10) and relative unpleasantness stature (e/D = 0.03-0.06). The Reynold number of the stream is shifted from 2500 to 16000. The hydraulic diameter of inner and outer duct of double duct of solar air is varied and an optimum value of hydraulic diameter is found out for maximum thermal efficiency. The effects of relative roughness pitch and relative roughness height on Nusselt number and friction factor have been discussed and the results are compared with the square sectioned rib roughened duct and smooth duct under similar flow conditions to investigate the enhancement in Nusselt number and friction factor. Roughness and flow parameters for artificially roughened solar air heater have been optimized by considering the thermo-hydraulic performance parameter based on constant pumping power requirement. It has been found that the square sectioned transverse continuous rib roughened duct with P/e = 10 and e/D = 0.06 offers the best thermo-hydraulic performance parameter for the investigated range of parameters

Home Automation Using Internet of Things
No full textIn this time of digitization and automation, the days of human beings is being paid simpler as approximately the whole thing is automatic, replacing the older manual systems. These days humans have finished internet an essential part of their each day life with no which they are powerless. Internet of things (IoT) provides a stage that allows devices to attach, sensed and proscribed somewhat across a network communications. In this research article we spotlight on home automation with smart phone and computer. The IoT devices reins and monitor the electronic electrical and the mechanical systems use in different types of building. The devices connected with the cloud server are restricted by a particular admin which make possible an amount of users to which a quantity of sensor and control nodes is associated. The admin can admittance and control all the nodes associated to each user but a particular user can control single the nodes to which the user itself is linked. This whole arrangement using Internet of Things (IoT) will allocate mobile devices and computers to slightly control each and every one the functions and features of home appliance from wherever around the earth by means of the internet link. The system considered is economical and can be extended as it allows association and scheming of a number of dissimilar devices

Analysis of K-Means and K-Medoid Clustering Algorithm on Various Datasets in Data Mining
No full textWith the development of information technology and computer science, high-capacity data appear in our lives. In order to help people analyzing and digging out useful information, the generation and application of data mining technology seem so significance. Clustering is the mostly used method of data mining. Clustering can be used for describing and analyzing of data. Clustering is a way of combining data objects or data points into disjoint cluster. The basic concept behind clustering is that the data objects in the same clusters should be related to each other and the data objects belonging to different clusters should differ from each other. This research article analyzes the performance of K-Means algorithm and K-Medoid algorithm on two different datasets. The algorithms are applied on cars dataset and banking dataset and results are compared on the basis of within sum square error
Study of Dyeing of Polyester Fabric using Peanut Pod Natural Dyes, Al2So4, CuSo4 and FeSo4 Mordanting Agents for Textile Engineering
No full textNatural dyes are gotten from plants, spineless creatures, or minerals. The greater sources of natural dyes are vegetable colors from plant sources-roots, berries, bark, leaves, and wood—and other natural sources, for example, parasites and lichens. Natural dyes are mostly used to color regular textures like cotton, silk, wool, jute and so on. In any case, next to no data is accessible on coloring of synthetic textures like polyester, acrylic, nylon and so forth. This paper is on utilization of natural dyes on natural fabrics as well as synthetic fabrics. The coloring of synthetic fabrics with natural dyes requires pre-treatments to produce hydrophilic groups. This paper highlights about the mordanting forms used to do coloring with natural dyes on natural fabrics and synthetic fabric
Graphic Art Effects on Consumer Behavior: A Study of Students/Youth in Iran
No full textThe paper illustrates how the power of graphic art advertisements facilitates the purchasing and as a result, consumption behavior. It bridges between the two sources ___ the decision of the purchaser/consumer on the one side, and the supplier on the other. The process eliminates negotiation, bargaining and the hard part of decision-making. Therefore, deals and interactions take place quicker under the power of graphic art advertisements. The article implicitly argues how the consumption market is strengthened and improved through graphic art advertisements. Patterns and culture of consumption are made and influenced by graphic art illustrations and advertisements. The article argues that while sociability supports consumption, isolation promotes withdrawal from consumption. Therefore, graphic art advertising bridges between production and consumption. Similarly, consumption contributes to the reproduction of culture, behavior and modernity. The research is based on the main hypothesis that: "graphic art values motivate and affect consumer behavior within the youth in the society". The present research investigates 470 students of age group18-29 of various disciplines and of both genders in Tehran City. In that, more female students 311 (66.2%), and less male students 159 (33.8%) participated in interviews
