The main focus of this work is to discuss the influence of the projectile’s length on the results of a Split Hopkinson Tension Bar (SHTB) experiment. By using the commercial software ABAQUS, finite element simulations of high-strain-rate tension experiments are accomplished on Aluminium 7017-T73 alloy specimens when varying the length of the projectile employed. The finite element analyses described herein are applied to simulate the effects of the variation of the projectile’s length on the measurements obtained in the incident, reflected, and transmission bars. Different strain rates are obtained when varying the projectile’s length always provided that its speed remains constant. The simulation results show that the projectile’s length has a significant effect on the strain obtained in the specimen and also on the subsequent stress-strain curve of the specimen. In view of this research, it can be concluded that the projectile’s length is a factor that can resolutely influence the interrupted dynamic tension experiment results since it has a significant effect on the strain obtained within the specimen. The simulations also provide complementary information to the experiments and an in-depth understanding of the specimen’s behaviour.

This paper presents modified Space Vector Pulse Width Modulation (SVPWM) techniques for Cascaded Multilevel Inverter. In the proposed SVPWM technique the reference signals are generated by adding offset voltage to the reference phase voltages. This SVPWM technique does not involve region identification, sector identification or look up tables for switching vector determination as are required in the conventional multilevel SVPWM technique It is also reduces the computation time compared to the conventional space vector PWM technique. The modulation signals are generated by comparing the reference phase voltages with triangular carrier signals. Cascaded multilevel inverter fed with Induction Motor and RL load is simulated for various carrier PWM techniques like PDPWM, PODPWM, APODPWM and PSCPWM. The simulation results are analysed and compared. Among the various modulation techniques, PDPWM is themost efficient one and has better spectral performance and better induction motor performance.

As a new technical approach, a hydraulic and magnetic clamp device was attempted to realize a magnetic clamp crane system that uses 8 simultaneously actuating individual hydraulic cylinders. Through this approach, a Sr type of ferritic permanent magnet(SrO ․ 6Fe2O3), not the previously employed electro-magnet, was utilized for the purpose of lifting and transporting the heavy weighted and oversized curved steel plates used for manufacturing the ships. This study is aimed at manufacturing and developing the hydraulic magnetic clamp prototype, which is composed of three main parts – the base frame, cylinder joint, and magnet joint – in order to safely transport such curved steel plates. Furthermore, this research was pursued to conduct a performance evaluation as to the prototype manufacture and acquire the planned quantity value and the development purpose items.

This paper investigates separately the effects of life and non-life insurance on economic growth in Nigeria from 1976 to 2013. The Autoregressive Distributed lags (ARDL) was adopted given the different order of integration of the variables of interest. After estimating a growth model, the bound test shows a long run relationship to exist among economic life, non-life insurance and economic growth in Nigeria over the period of study. The long run and the short run dynamics further confirms the positive and significant contribution of life and non-life insurance on economic growth in Nigeria. The paper concludes that life and non-life insurance acts as complements to economic growth in Nigeria rather substitutes.

In this experiment, we have attempted to investigate the effects of yarn count on crimp% and take-up% of 𝟐𝟐 𝟏𝟏 (S) twill weave design. Experimental studies were conducted by woven fabrics with five different yarn count. For this purpose five woven fabric samples, each of 𝟐𝟐 𝟏𝟏 (S) twill designs with different count, were made on same rapier weaving machine by keeping all parameters constant with same atmospheric condition. Crimp% and take-up% was calculated by dividing the difference between umcrimped length and crimped length of yarn by crimped length of yarn and uncrimped length of yarn respectively. It was observed that when the count of yarn changes the crimp% and take-up% of yarns are affected. Finally found that, as expected, with increase of yarn count the crimp% and take-up% of warp yarn decreases while crimp% and take-up% of weft yarn increases.

Effect of four storage temperatures (T1-ambient room temperature (35±5ºC), T2-Air conditioner (25±2ºC), T3- Fridge (5±1ºC) and T4-Freezer (-4±1ºC) and four moisture levels M1 (38%), M2 (21%), M3 (12%), M4 (5.5%) were studied on seed longevity of seeds under controlled conditions. After setting of desired moisture content seeds were then subjected to storage treatments in 200μ thick polythene bag and kept in airtight plastic container at different temperature levels and tested upto 270 days respectively. Seeds were sown in between paper (BP) for germination study in laboratory at 30±1ºC and relative humidity (90±3%).

Developing high-quality reliability models is one of the key concerns in the domain of software reliability. The enhanced software reliability model ought to give superior predictions of upcoming malfunction manners, calculate helpful quantities and be extensively relevant. Hence, an extremely significant purpose of existing software reliability study is to build up broad prediction models, for a software supervisor, it is imperative to be capable to foretell the upcoming performance of the fault discovery and rectification procedure. The forecast is imperative for the allotment of additional testing assets and for the learning of software release troubles. No solitary step only is ample to decide the most excellent constraint assessment technique on a specified dataset. In reality, software supervisors would have a preference to observe steadily minor proportion of the data forecasted, as the more the testing procedure runs, the extra costly it becomes. In this direction, this paper key center is to provide high-quality forecasts to evaluation procedures for software testing.

The main objective of this study is to ascertain the socio-economic determinants of income poverty in rural areas of Ethiopia. A Simple random sampling was used to select 217 household heads from two rural areas Dodola district, Oromia Regional State, in a year 2012. The Binary logistic method was used to find out the determinants of income poverty. The result reveals that determinants of income poverty include household size, number of income sources of the household, livestock and farm land ownership. Poverty status is negatively associated with number of income sources of the household, livestock and farm land ownership. However, family size is positively related to poverty. Finally the study suggests the rural households should diversify their income sources. The households should also be effectively involved in family planning.

God has garnished our land with sublime attractions and blessed us with in-born hospitality. So, Tourism is truly expected to flourish in Bangladesh but due to the lack of proper planning and strategies from the policy making levels, information sharing mismanagement and tourism stakeholders below standard performances have yet created a messy tourism industry. This study wants to find out the current scenario of STSCM in Bangladesh as well as how to develop STSCM for tourism industry in Bangladesh supported by a contingency approach if something goes wrong in STSCM and also if anything creates obstacle in the STSCM from outside. Our tourism industry is yet in its early days, so if we encapsulate all the components of tourism supply chain, it will add value to tourists and tourism businesses. The result of the study is vital for NTO and the Tourism Stakeholders to understand the framework and execution process of STSCM. In fine, Tourism authorities will find the study relevant and a platform which are the today’s demand for the tourism industry of Bangladesh.

The present study about pitfalls of impulse purchase has been carried out from customers’ stand point of view. The study intends to educate and to create awareness among those class and category of customers who surreptitiously fall prey of lucrative packages and offers of products marketed and merchandised in super/hypermarket and malls. The present research intends to create awareness among customers who hardly give priority to the inherent worth and durability of goods and services provided by the dazzling and mind blowing slogans. There are certain class and category of buyers identified and located by the expert or analysts and managerial apparatus of impulse purchase - offer lucrative products and slogans in order to give boost and fulfill their sales target. Furthermore, the promises mentioned in products’ features are just a violation of the basic agreement either partially: in quality or in other characteristics.
