Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 9

Abstract

Purpose - Housing associations make too small a contribution to society, the government has to step in too frequently because of maladministration, and the associations' executives are often unaware of the far-reaching impact of their decisions. These are the conclusions of new academic research conducted by Jan Veuger of Rotterdam School of Management, Erasmus University (RSM). In his dissertation, he asserts that in numerous cases there is no correlation between social and financial objectives. The Dutch House of Representatives debated the results of the report Ver van huis from the Parliamentary Committee of Inquiry on Housing Associations in early December 2014.

KEY WORD: housing associations – social values – consistency – responsibility

A Study on the Intensity of Vowels of Disyllabic Words in Sundanese

China
Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 9

Abstract

In this study, the effects of syllable position, syllable type and vowels on the intensity of disyllabic words in Sundanese are analyzed. It is shown from the result that, in Sundanese, for disyllabic words, the first syllable tends to be stressed, so the intensity values of vowels in the first syllable are larger than that in the second syllable. As the CVC syllable is phonologically heavier than the CV syllable, the intensity of CVC syllable is higher than that of the CV syllable. The intensity value of low vowel, /a/, is larger than that of high vowel /i/ and /u/, which is due to the fact that low vowels have a higher intrinsic intensity than high vowels.

KEY WORD: Syllable, vowel, intensity, stress

Abstract

Nanoparticles have attracted great attention in different fields as they show unique properties which can't be attained by conventional macroscopic materials. Low cost additives like nanoparticles play a vital role in modern lubricants. It improves the performance and life of machines by reducing frictional work, wear and prevents failure of its components. In the situations of high thermal loading and high heat flux nanofluids with stabilized nanoparticles emerge as a key for efficient heat transfer. Here a performance analysis was conducted on a hermetically sealed compressor in a domestic refrigeration system working with conventional POE oil lubricant. the POE oil is replaced by SUNISO3GS mineral oil. Nano lubricant samples of POE+ silver nanoparticles oil mixture, POE +tin nanoparticles oil mixture, POE +nickel nanoparticles oil mixtures SUNISO3GS+ silver nanoparticles oil mixture, SUNISO3GS............

How CREM strategies apply to primary school buildings

Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 9

Abstract

The purpose of this paper is to investigate which theoretical elements of adding value with? real estate are applied in practice in accommodating primary education and in what way these are elements relevant to the stakeholders. A literature study of usual CREM strategies has been used to build a theoretical framework with regard to the value a building can create for different stakeholders. Interviews were then held with various professionally involved people in order to understand to what extent the general theory is taken into account with regard to "added value" for the stakeholders of primary school buildings. The data show that CREM theory also can be applied to the "not for profit" school buildings, but that not all potential possibilities to add value with real estate for primary education seem to be applied in practice.

Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 9

Abstract

In this study, object tracking and object capturing application were realized according to the data obtained using image processing techniques and pid speed control was implemented to object catch. Image processing software and DC motor speed control program were programmed on the Raspberry pi 3 card in python language. The red and round properties of the object are defined to image processing and OpenCV library is used. The object tracking was realized and its position was determined with the result of filtering operations on image processing. According to the obtained position information, the object is caught by the robot.

Abstract

TToday's technology has been evolved into stand-alone systems which can do all necessary process by itself without any additional hardware. Advance microcontrollers have become microcomputers that is also known as single board computers. These systems take their power from powerful microcontrollers. These microcontrollers have many integrated circuits onboard so they can achieve many different process by themselves. They are being used in many applications from powerful industrial device to simple home appliance. On today's market, there are many different microcontrollers with different structure and capabilities. Therefore, understanding the concepts related to the microcontrollers is really important for choosing the best hardware. This paper presents main concepts of microcontrollers and reveals basis of their structure. Their components and abilities have been discussed and comparation of well-known single board computers has been given.

Numerical Investigation of Cavitation Problem on A Specified GeometryNumerical Investigation of Cavitation Problem on A Specified Geometry

Abstract

Cavitation can be a significant thread for hydraulic structures. This phenomenon occurs when vapor pressure drops below static pressure. Occurrence of the cavitation can cause cavitation erosion that can damage the parts of the pipes, turbines or pumps. In this study, pipeline system which will be constructed in a part of hydraulic works is investigated numerically using commercially available ANSYS Fluent software in terms of cavitation problem. By varying inlet boundary condition, the maximum velocity that cause cavitation not to occur and the velocity that cause cavitation just to occur is determined. Results of the numerical simulations are visualized. In addition, minimum static pressure and maximum velocity of the pipeline system are determined and compared with the vapor pressure. It is shown that for the given boundary conditions, cavitation does not take place. On the other hand, if the inlet velocity is increased to 5.7 m/s or further, cavitation can be observed depending on flow and structural conditions

Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 6

Abstract

Deep drawing is one of the important sheet forming process used to make cup shaped components. In sheet metal forming, it is essential that the formed components are to be free from any defects such as undesired thinning, fracture, wrinkles or shape distortion etc. The die tryouts to achieve the defect free components will result in high cost of tooling and set up. Now a days numerical simulation is widely used to eliminate the costly trails. The accuracy of such simulations depends on the input parameters of the simulation. In this work, a parametric study was carriedout for the selection of appropriate input parameters for the finite element simulation such as material model, number of integration points and type of element that could ultimately lead to a reduction in lead time in the design of deep drawing process. The material considered for the study was Super duplex stainless steel sheet of grade (S32750). A commercially available finite element code Dynaform/Lsdyna was used in the simulation. The punch stem diameter, depth of drawing and the blank diameter were selected according to the benchmark specification given in Numisheet'2002.The results of experimentation and simulation were compared for the validity of simulation approach.

Research Inventy: International Journal of Engineering & Science , Volume 7 ~ Issue 6

Abstract

Scientific computation aims to analyze and predict natural and engineered phenomena for human understanding. Specific quantification of physical variables requires annotations of physical units, either basic or derived. State-of-the-art computation uses the object-oriented programming (OOP) features using a number of processing cores. In translating scientific governing equations to computer programming, developers are still responsible to use and convert physical units to provide meaningful results. In this paper, we indicate some incoherency of SI units and propose possible ways to minimize unintended numerical errors. We use standard Fortran 90 as a programming language and discuss how physical units can be specified and checked during code compilations and executions.
