To study the impact and usage of test parallelization

The number of test cases required to ensure the quality of a software system grows hand in-hand with its complex and henceforth the total test execution time increases proportionally. Traditionally test cases are executed sequentially which takes much time. Thus parallel test execution appeared to be an appealing option to cut over the test execution time .This paper presents our findings on different techniques for test parallelization and its impact with respect to time and test flakiness. Test flakiness is the tests that fail randomly. We have applied the different techniques on a java project containing 623 test cases and observed the effect.Based on the result we have tried to conclude the optimal technique for test parallelization.

Improvement in production rate by reducing the defects of die casting process by DMAIC approach

Six Sigma’s problem-solving methodology DMAIC has been one of several techniques used to improve quality. The work follows the DMAIC methodology to investigate defects, root causes and provide a solution to reduce/eliminate these defects. The analysis from employing Six Sigma and DMAIC indicated that the metal melting temperature, die temperature and die holding time influenced the number of defective items produced. In particular, the design of experiments (DOE) and two-way analysis of variance (ANOVA) techniques were combined to statistically determine the correlation of the metal melting temperature, die temperature and die holding time with defects as well as to define their optimum values needed to reduce/eliminate the defects. As a result, a reduction of 16.93 % to 10.04 % in the terminal cover and 16.62 % to 8.97 % in the din based cover was achieved, which helped the organisation studied to reduce its defects per million opportunities (DPMO) and thus improve its Sigma level from 2.53 to 2.79 for the terminal cover and 2.55 to 2.85 for the din based cover.

Gearing up engineers for the global employability pursuit

We are all aware of this perplexing, wave which is driving the global professional scenario towards a multifarious warfare arena. The saddest part now which today’s youth faces is that all the players are not actually equipped with the ammunition of skills, equitable, comparable, or even commensurably parallel in proximity. The result is horrendous, bewildering, crisscross, display of ammunition, unworthy of any determinative accomplishments. Satisfaction is improbable, unimaginable, and impossible for entities on both the sides of the table. India is a country with one of the largest tertiary age population. Under such circumstances, where the country has a huge youth power, which can be used to convert the economy of the country into a booming one. Yet we are at such a juncture there is a huge gap in the skill sets offered by job contenders and that expected by employers. The result of which is the rise of professionally qualified yet unemployed youth. Extensive research and brainstorming on a massive scale is being carried out at all levels, both by the government and non-government organizations, to decide the requisite parameters, a well-defined paradigm and obviously means to precisely define the set of employability skills. What exactly are these employability skills and how they are to be developed and implemented is the most pertinent question? Can a curriculum be accurately designed for employability skills? In bits and pieces through the information is disseminated, nevertheless, the “what” and “how” of the concept is still far from the general comprehension of the majority of today’s youth looking out to be employed. This paper discusses what these employability skills are, how they affect the employability status of today’s youth. Especially from the point of view of engineers, it’s important how best skills can be integrated with their academic regime, to improve the employability status. The imperative task lays ahead and questions are like how best to gear up the education system to meet the growing demand of the industry. We still have a long way to go, but one thing is certain a robust partnership between the industry and the universities, – the two crucial stakeholders, to chalk our strategies foreseeing the future only, can lead us to the destination we are all dreaming of!

Experimental study on fresh and hardened properties of concrete by incorporating fly ash, metakaolin and brick powder by partial replacement of cement for M40 grade concrete

The present dissertation is on replacement of fine aggregate, as metakaolin, brick powder & fly ash, in this present construction concrete world the natural resources are undergoes to depletion and wastage of various materials are increased day by day. The construction growth also increased due to the heavy population .in this present manuscript the various materials are used as fine aggregate and check the concrete characteristics at various curing periods and know the behavior of the concrete. In this present study deals with the strength properties of concrete by using flyash,metakaolin& brick powder as partial supplements for fine aggregate at 0,5,10,15,20 at various curing periods 7,28,56 days. The use of materials in cement concrete a) Materials will modify properties of the concrete b) Control the concrete production cost c) To overcome the scarcity of fine aggregate d) clever usage of waste materials

Fabrication and mechanical behaviour of limonia acidissima ash – silicon carbide reinforced AL2024 alloy matrix hybrid composites

In the present scenario, Aluminium metal Metrix hybrid composites are widely using for aerospace applications, transport applications and structural applications due to their desirable properties. In view of this, the present investigation was aimed to synthesized aluminum –silicon-agro waste based hybrid metal matrix composites.The present experiment was carried out to examine fabrication characteristics and mechanical properties of Aluminium hybrid metal matrix composite. In the present investigation, Al 2024 reinforced with silicon carbide (Sic) and Limonia acidissima ash for developing the mechanical properties. The composites were synthesized by the stir casting technique. The composites were synthesized by varying Limonia acidissima percentage of weight as 0%, 2%, 4%, 6% and 8%. The mechanical properties of Tensile strength, Yield strength, the percentage of elongation, hardness were performed. The microstructural study was carried out by SEM examination.

A survey on rectangular patch antenna using a various shaped patch antenna

Microstrip patch antennas are most commonly used in dense, conformal and low- cost wireless applications because of the advantages over the traditional antenna. In this paper, the small introduction of microstrip antenna along with various patch shapes are discussed in detail. Numerous techniques are used to improve the parameters such as bandwidth, return loss, gain, and efficiency of the antenna. In this paper, different feeding techniques such as coaxial cable, line feed, Aperture coupled and proximity coupled feeding techniques along with their advantages and disadvantages are discussed. The formulas used for calculating length and width of patch and ground antennas are provided. The antennas with different slots on patch such as Triangular slot, E shape, Single U shape, Double U shape, fractal techniques are discussed.
