This study developed a five-axis machine center that integrates two mechanical models: a three-degree-of-freedom parallel platform and traditional computer numerical control (CNC) X–Y table. In the design of the mechanism, the three actuator axes are parallel to each other, and the two platforms are installed in parallel. The positions of the moving platform are changed by extending and shortening the three axes. To verify the machining precision and usability of this machine, this study used the post processing program to transfer the numerical control code using five-axis machining software to determine the processing path; the Z, a, and ß values of the numerical control program are used to convert each axis value of a three-axis motion platform through inverse kinematics. Finally, this study used two machining methods in the design: actual concentric roughing and actual spiral roughing. Machining experiments were conducted to verify the accuracy of the proposed method.

In present scenario due to high competition in market, there are lots of pressures on organizations involbs with transportation industry, to provide the service in a better and effective manner. The distribution of products among the customers in systematic manner is not an easy task. Transportation models provide an effective framework to meet these challenges. In an uncertainty environment, it is a too difficult to handle a multi-objective transportation problem with fixed parameters, rather it is easy to consider all related factors in terms of linguistic parameters. Different objectives of a multi-objective transportation problem are affected by multiple numbers of criteria like route of transportation, weather condition, vehicles used for transportation etc. In this study a multi-stage multi-objective transportation model is developed with fuzzy relations. Minimization of both cost and time of transportation are considered as two different objectives of first stage which are associated with a number of different criteria like detortion time, fixed charge and mode of transportation. In second stage, another objective i.e quantity of transported amount is considered on the basis of previous two objectives. All these factors considered for this model are imprecise in nature and are represented in terms of linguistic variables. The fuzzy rule based multiobjective transportation problem is formulated and Genetic Algorithm for multiobjective problems (MOGA) is used to find optimal solution. The model is presented with a numerical problem and optimum result is discussed.

Computer training of technological process operators is recognized worldwide as an effective means of reducing accidents and increasing production efficiency by improving operator`s skills. The use of computer simulators for training operators of potentially dangerous industries is fixed in regulatory documents of many countries, including Russia. Most enterprises in the oil and gas industry have already equipped their training centers with computer simulators; however, the metallurgical sector and other representatives of the chemical engineering industries do not use and often do not consider a computer simulator as a tool for improving efficiency and production safety. World statistics shows that among the causes of industrial accidents, operator mistakes are firmly in second place. They account for an average of 40% of all emergency incidents. Computer training is the most powerful and effective means of dealing with the operators mistakes. With the help of a specialized simulator, with a high degree of accuracy, imitating the work of a dangerous technological installation, relating to the oil refining or metallurgical industry, it is possible not only to familiarize operators with potential emergencies and develop a strategy for preventing accidents, mitigating or eliminating its consequences, but also working out actions operators to automatism. A good full-scale simulator allows to work out detailed measures to prevent accidents, as well as plans for the localization and liquidation of emergenciesThe article presents an overview of the current state of the industry of technological simulators, examines existing technical solutions, global manufacturers and simulators using aspects

Achieving the highest possible efficiency from a propeller is needed to minimize fuel. However, this is limited by the occurrence of cavitation, vibration, noise and material strength possessed by propellers. Thus it is necessary to do a new breakthrough in designing or modifying the shape of the propeller to achieve maximum performance. One modification that can be done is to change the skew angle. Propeller B-Series is a propeller that is often used and has a fairly complete geometry data. Cavitation is something that must be considered because it will manifest into noise, vibration and erosion in the propeller blade. The modification of the skew angle will be analyzed using the CFD (Computational Fluid Dynamics) method of how the relationship between performance and cavitation results from the various variations that have been made. So that later it can be known that skew angles produce maximum performance and low cavitation. From the simulation results it can be concluded that the greater the skew angle, the value of the thrust and torque aredecrease, but this is inversely proportional to the value of efficiency that has an upward trendline with the greater angle of skew. Increasing the skew angle can reduce the potential of cavitation at certain skew angles. The skew angle which has a thrust value, torque, and efficiency that is quite high and has a fairly low cavitation potential is at the skew angle 0°

Multiple human tracking based on object detection has been a challenge due to its complexity. Errors in object detection would be propagated to tracking errors. In this paper, we propose a tracking method that minimizes the error produced by object detector. We use RetinaNet as object detector and Hungarian algorithm for tracking. The cost matrix for Hungarian algorithm is calculated using the RetinaNet features, bounding box center distances, and intersection of unions of bounding boxes. We interpolate the missing detections in the last step. The proposed method yield 43.2 MOTA for MOT16 benchmark

Modified Sukhoi with Gripen wing was under investigation. The Sukhoi Su-30 maneuverability at very high angles of attack (AoA) was preserved and intensified with the advantage of slotted Gripen wing. The angle of canard in collaboration with fighter wings created a pattern of flow so that at the maximum of AoA the fighter has a higher lift coefficient than without the Gripen wing. The behavior of changing the angle of canard configuration played a crucial role in producing a sturdy core of vortex so that it could create an increased lift. Canard body vortex cores interacted strongly with the vortex core from slotted Gripen wing that the resulting vortex core merging increased lift dramatically. The use of fluid dynamics computation (CFD) based on vortex strength had attained detailed and clear visualization and aerodynamic data in uncovering the vortex dynamics occurrence. It was uncovered that at the AoA 400 , the modified Sukhoi Su-30 with Gripen wing was capable of creating the most potent flow relation from the main wing caused by the canard. It was clear that the formation of the merging of the vortices above the canard of the fighter was obviously evident resulting into stronger vortices.

A model of the movement of bulk material with regard to its stress-strain state in the working chamber of a centrifugal crusher with inclined blades is proposed. The results of the model allow us to determine the kinematic and geometric characteristics of a uniform flow of particles of bulk material as it leaves the cell of the apparatus between the blades. The evaluation of the design parameter of the blades for the implementation of the condition of uniformity of the specified flow before the impact on the bumping surface

The present study investigated a lightweight optimal design method that considers the static and dynamic environment of a child pop-up seat, which is a convenience device applied to vehicles. This paper presents a method for deriving a lightweight optimal design model by applying topology optimization and an experimental design method. For this purpose, this study changed the existing metal material used in the leg part of a child pop-up seat to a plastic material, and simultaneously considered the static and dynamic environments when applying sled test conditions. The density method was used to derive the initial shape of the child pop-up seat leg part in a static environment. Furthermore, the leg part was designed based on the stress distribution, and an optimization algorithm in the dynamic testing environment was applied to derive a thickness value that satisfied the allowable stress. The effectiveness of the lightweight optimal design model was verified through a comparative analysis between the model that considered the existing static environment and the model that simultaneously considered the static and dynamic testing environments.

The convective heat transfer rate inside a flat tube radiator of an automobile using CuO-Water nanofluids were investigated experimentally and numerically. Nanofluid of 0.1%, 0.2%, 0.3% volume concentrations were prepared using CuO nanoparticle with water as base fluid. The effect of mass flow rate, volume concentration inlet temperature on heat transfer rate with varied coolant mass flow rate ranging from 6LPM, 8LPM, 10LPM were examined. Results shows that heat transfer rate linearly increases with increase in mass flow rate and volume concentration, the best heat transfer rate is achieved at 0.3% volume fraction of CuO at 10LPM. A maximum enhancement of 35% in heat transfer rate is obtained for 0.3% concentration of CuO nanofluid.

In this paper, free and forced vibration of functionally graded beam are investigated, the develop theory based on the refined method considered the variation of transverse shear strain and stretching through the FGM beam at the simple supported boundary condition. The properties of the material change continuously through the thickness of the beam, these characteristics vary according to a power law. The aim of refined method is to reduce and simplify the number of unknowns by divided the transversal displacement into shear, bending and stretching displacement. Based on Hamilton’s principle, the governing equation of motion beam is obtained. The present results are compared with current and different solutions in order to validate the sequence development of the analytical solution. However, the power law index, shear and stretching deformation have a significant influence on displacement stress and frequency

This research assesses the factors influencing construction site operative training in Nigeria with a view to enhancing safety practices among construction sites operatives. A cross-sectional research design was adopted, where snowballing and random sampling techniques were used to select the construction company and the respondents. Respondents to be sampled were drawn from the list of professionals in the built environments such as Architect, Quantity surveyors, Builder and the Engineers and site operatives such as skilled, unskilled, semi-skilled labors and operators working with each construction company. Data were collected using a wellstructured close-ended questionnaires designed based on the stated objectives of the study. 188 copies of questionnaires were distributed out of which 137 was completely filled and returned, representing 72.9 response rate. Returned data were analyzed using percentile, Relative Important Index (RII) and independent Sample T-Test with the aid of the Statistical Package for Social Science (SPSS) software version 21.0. The result revealed that changes in government policy, poor job performance, quality improvement, high rate of rework and technological changes were the major ranked factors influencing construction site operative training in Oyo State. It further show that there are significant difference in the opinion of site operatives and professionals on organizational peer pressure, high level of material wastage and promotion exercise or change in position. The study concludes that operatives in the study area tend to be trained only when there is change in government or organization policy. The study recommend that government/organization should frequently review there policy in favor of operative training

Cloud computing is presently playing a significant role in the provisioning of vital services in information technology. A unique aspect of cloud computing is the cloud middleware and other related entities which supports applications and networks. Determining a particular research area especially in terms of cloud middleware and services at all levels could be a cumbersome process for a researcher, hence the need for reviews and paper surveys that identify research gaps. The purpose of this paper was to conduct a systematic mapping study of cloud computing middleware, stacks, tools and services at all layers. The focus was on three facets of studies, the research facet, topic facet and contribution facet. The results showed that there were more publications on tool in the contribution facet with tool, model, method and process having 18.10%, 13.79%, 6.03% and 8.62% respectively. In addition, evaluation and solution research had the largest number of articles in terms of tool with 14.17% and 26.77% respectively. A most striking aspect of the systematic map is that solution research has the highest frequencies of publication in relation to all aspects of the topics extracted for the study. This study clearly identified gaps in the field of cloud computing middleware, which should stimulate interest for further studies by both researchers and industry practitioners

Industrialization of the Nigerian economy started with the establishment of fully integrated large-scale industries for rapid development of the sector. However, inability of the strategy to fast-track economic growth in Nigeria led to a shift to small-scale industries. As opposed to the complex and sophisticated nature of the former, the latter strategy is characterized by simple technology which available industrial infrastructure could readily support. A blend of the right choice of technology and strong economic fundamentals is imperative for a vibrant and robust manufacturing sub-sector. This paper estimates the impact of key macroeconomic indicators on manufacturing performance in Nigeria using the method of vector autoregression (VAR). The study focused on the industrial strategy based on small-scale industrialization. The variance decomposition result shows that variations in manufacturing capacity utilization in Nigeria are largely driven by shocks to its lagged values. The result further shows strong positive impact of trade openness on manufacturing capacity utilization. The study therefore concludes that manufacturing performance in Nigeria is partly driven by shocks to own innovations and partly by trade policy shocks.

It is nearly impossible for any manufacturing firm to produce all inputs whether raw material or intermediate inputs required for its production processes. Consequently, industries depend on the resources of one another. In economic interplay of industries, bottleneck problem do occur where one industry may not be able to satisfy the demand of the other industry. Hence, the review effort seeks to document the underlying relationship between vertical integration and bottleneck problem arising therein inter-industry production system to guide industry stakeholders in making decisions and policy formulations for improved production performance. The appraisal pinpoints “resources dependent” as the primary bottleneck problem in inter-industry production system. In addition, the review established that firms attempted to solve resources dependent problem by implementing vertical integration because it ensures reduced marketing cost, stable operations, and certainty of supplies. In addition, it motivates control o f product distribution, high quality control, timely revision of production policies, and healthier inventory control among other benefits particularly for products whose components are highly inter-related and dependent. Hence, vertical integration is tool to address resources dependent problem but requires econometric model to determine the threshold and limit of its implementation in production environment

In production environment, supply chain system is a tool for attaining efficient production performance because it streamlines and optimizes the entire production processes. It appears that research efforts so far only supported arguments for the benefits of supply chain management in production environment without taking into account problems associated with the administration of supply chain system within production setting that constitute impediment to production throughput and make it difficult for manufacturers to satisfy customers’ demands. Consequently, the aim of the review effort is to highlight the importance of supply chain management and identifies the underlying bottleneck problems related to supply chain administration in production setting to guide stakeholders in policy formulation for further production performance. Notable among the problems identified that are attributable to supply chain organization in production environment are, supply disruption, lack of agility to respond to supply and demand fluctuation, inadequate logistics, lack of adaptation to evolving market, inaccuracy of information between the extended enterprises, ineffective integration and coordination of supply chain strategy across the functional units, lack of capacity and resources availability, lack of quality and regulation compliance. Based on the identified problems, we developed a supply chain appraisal tool for pre-qualification and selection of supply chain vendors in production environment.

The visual ergonomic is a very effective tool in preventing visual problems through environmental and postural advice. One important field in visual ergonomics is the eye ellipse. Eye ellipse may be defined as the imaginary elliptical boundaries beyond which the iris of the eye cannot reach. So far, the eye ellipse is defined only with the manikin features i.e., different manikin has different eye ellipse and this eye ellipse remains the same all times. Ergonomical evaluation software like RAMSIS, Jack, etc... also uses the same principle to define the parameters. As of now, a truck driver in his neutral position will have the same eye ellipse as when he drives a race car in the neutral position. So, we are doing a study in which we estimate the eye ellipse of manikin with respect to its H-point and also to find the parameter which has a peculiar effect on the eye ellipse.

Due to a considerable increase of electric energy demand and greenhouse gases emission in South Africa (SA), renewable energy (RE) systems are an important option to overcome this challenge. This paper presents an assessment of electric energy production using new manufactured photovoltaic (PV) systems in KwaZulu-Natal (KZN) province. It has been found that electricity can be produced using PV technology with higher performance of 102.30 W/m2 for SPR-P17-350-COM PV module and 97.15 W/m2 for SPR-P19-400-COM PV module obtained at the site SM10 and low performance of 81.54 W/m2 for SPR-P17-350-COM PV module and 81.32 W/m2 for SPR-P19-400-COM PV module obtained at the site SM04. This encourage the use of PV technology in the province to overcome the growing demand of electricity and reduce the emission of greenhouse gases produced by the coal-fired power plants

The use of power in corporate settings tends to influence the organizational climate which is related how much employees commit to the progress of a firm. In this paper, qualitative content analysis is used to assess how power-game in Nigerian manufacturing firms influence workers’ productivity. Fifty (50) full time employees were randomly selected across five (5) manufacturing companies in Nigeria. A semistructured, open-ended interview schedule containing 10 questions related to power and productivity was administered on the employees. Using qualitative approach (content analysis), Cohen Kappa inter-coder reliability calculations showed that at 54 percent, themes such as coercive power, reward power and legitimate power were dominant, pointing to formal power forms. In turn, these bases of power negatively affect openness and commitment on the part of employees. As such, it is suggested that corporate individuals who have access to power entrusted by organizational authority must make use of personal power forms; such as referent and expert powers to effect high productivity among employees
