While robust optimization techniques have been found useful for the modeling of uncertainties in a wide range of fields, their application to concurrent engineering optimization models have been limited. This research introduces new integer, non-linear programs for the robust concurrent design of product families and their corresponding assembly systems. The models introduced involve the application of interval and ellipsoidal uncertainty functions to the solution of the latter problem. A new, exhaustive search algorithm for the determination of exact solutions to the models is also introduced. The implementation of the model is demonstrated with an example.

It is generally accepted that having a proper river crossing point has a positive effect on rural inhabitants. Such crossing points would increase the ability of communities to access their social services, markets, jobs, and thereby lead to raising their standard of living. In line with this objective,Rwanda has been promoting the construction of pedestrian footbridges in rural areas, and with different partners, different pedestrian footbridges have already been constructed. It is very crucial that all institutions involved in the construction of pedestrian footbridges, both public and private, consider the financial benefits of pedestrian footbridges and some significant direct and indirect effects on the rural communities.The Objective of this study was to identify all possible benefits that may be generated by pedestrian footbridges to understand the potential range of their impacts in rural areas and the likely responses from those people impacted by the project. The study also proposed a comprehensive approach for estimating the economic impacts of a pedestrian footbridge in rural areas. The methodology involved community interviews conducted during site visits to identify and predict possible impacts due to the lack and availability of safe access via pedestrian footbridges.

The work in this paper deals with reconstructing and optimizing the wing geometry of an Unmanned Combat Aerial Vehicle for improved performance and reviewing the impact of the modification on flight parameters in a steady flight. The behavior of airfoils at planned flight conditions under I.S.A. is checked in XFLR5 software. Following up by 2-D CFD and boundary layer analysis of former and new airfoil, dimensions of the wing are re-developed, keeping the fuselage and tail structure same. The existing wing and the optimized wing design is analyzed by Vortex Lattice Method and Triangular Panel Method, with an objective to make the shape of the wing aerodynamically suitable for an increased Lift to Drag ratio and thereby minimizing drag coefficients.

In this paper, an unconstrained quadratic programming problem with uncertain parameters is discussed. For this purpose, the basic idea of optimizing the unconstrained quadratic programming problem is introduced. The solution method of solving linear equations could be applied to obtain the optimal solution for this kind of problem. Later, the theoretical work on the optimization of the unconstrained quadratic programming problem is presented. By this, the model parameters, which are unknown values, are considered. In this uncertain situation, it is assumed that these parameters are normally distributed; then, the simulation on these uncertain parameters are performed, so the quadratic programming problem without constraints could be solved iteratively by using the gradient-based optimization approach. For illustration, an example of this problem is studied. The computation procedure is expressed, and the result obtained shows the optimal solution in the uncertain environment. In conclusion, the unconstrained quadratic programming problem, which has uncertain parameters, could be solved successfully.

Drying is an important agricultural process, particularly for crops, and shriveled products are used all over the world. The performance of drying green chili was also tested in this article, which created an alternate way of drying agricultural products. The goal of this study is to provide a solar biomass hybrid dryer with improved design, construction, and performance testing. During most hours of the trial, the temperature within the solar collector and dryer was sufficiently higher than the ambient temperature, according to the results obtained during the test period. The temperature of the ambient air at the collector intake ranged from 30 to 35 degrees Celsius. The temperature of the air at the collector's outlet ranged from 54 to 64 degrees Celsius, while the temperature of the drying chamber ranged from 51 to 60 degrees Celsius, making it suitable for drying green chili and a variety of other agricultural products. The collector was found to be 46.54 percent efficient. The findings revealed that the alteration of the collector, which produces turbulent air flow and improves chamber wall insulation, affects drying. Based on the results of this study, the created solar biomass hybrid drier is cost-effective for small-scale crop growers in rural areas of developing countries.

There are three reasons why laws such as q = hΔT and σ = Eε, and parameters such as h and E, should be abandoned. 1. The laws are analogs of y = (y/x)x and, if y is a nonlinear function of x, analogs of (y/x) (such as h and E) are extraneous variables that greatly complicate problem solutions. 2. Parameters such as h and E were created by assigning dimensions to numbers, in violation of the modern view that dimensions must not be assigned to numbers. 3. The laws purport to describe how the numerical value and dimension of parameters are related when, in fact, equations can rationally describe only how the numerical values of parameters are related. When conventional engineering laws are abandoned, they will be replaced by new laws described by the following: 1. They are dimensionless because parameter symbols in equations represent only numerical value. 2. They are analogs of y = f{x}. 3. They contain no analogs of y/x, and consequently they contain no extraneous variables. 4. They make it possible to abandon analogs of y/x (such as modulus and heat transfer coefficient), greatly simplifying the solution of nonlinear problems by reducing the number of variables. 5. They have no parameters that were created by assigning dimensions to numbers. 6. They are inherently dimensionally homogeneous because parameter symbols in equations represent only numerical value. 7. They state that the numerical value of parameter y is always a function of the numerical value of parameter x, and the function may be proportional, linear, or nonlinear.

Wind tunnel (WT) is a device that artificially produces airflow relative to a stationary body and measures aerodynamic force and pressure distribution, simulating the actual conditions with an important aspect of accurately feigning¬ the full complexity of fluid flow. The aim of the present study is to design the three dimensional geometry of a small, open-circuit (also known as Eiffel Type), and subsonic (low speed) wind tunnel (WT) capable of demonstrating or acting as a vital tool in aero-mechanics research. The project and fabrication itself, poses as an onerous task with the cynosure/central theme being the delineation/depiction of wind tunnel components such as Test Section, contraction cone, diffuser, drive system and settling chamber.

The need to choose appropriate methods to ensure quality of continuing engineering education has been an issue of research and of practice for years. Several initiatives were undertaken in the last decades to define the methods of proper assurance of provision and delivery of continuing engineering education. The quality models for education and training have a large variety of approaches that have been applied to all different levels from primary schools to adult learning. Methods employed had no significant success with continuing engineering education due to the particular nature of the training. A proposal for a project was elaborated between universities in Europe and in the USA to develop accreditation procedures to ensure quality of continuing engineering education (CEE) centres. The project (DAETE)applied an adaptation of the EFQM (European Foundation Quality Management) descriptors to the specific contexts of CEE centres. The DAETE model had also been applied in other contexts like accreditation and classification of CEE centers and for training managers of CEE centers staff. The paper also describes these applications of the model in different contexts with emphasis on useful conclusions. Recommendations for the adoption of the EFQM model to organizations involved in education and training are made with the consequent adaptations.

In this work, a system able to monitor the crowd density detecting mobile phone communications through the analysis of the electromagnetic spectrum is proposed and experimentally assessed. The variations of the electromagnetic spectrum are collected with a low-cost spectrum analyzer, and a high gain log-periodic directive antenna (LPDA). The objective is to relate the spectral power density in a given frequency band to estimate the connections present and the number of people in a given area. In particular, a linear regression estimator, whose parameters have been calculated with the least square method modeled considering experimental data in a controlled environment, permits us to infer the number of customers detected on a given frequency band. The obtained experimental results demonstrated the efficacy of the method, which can be used not only to monitoring the number of people in a given scenario, but it also be used for commercial activities to detect the presence and pervasiveness of different mobile phone companies.

Ten years have passed since the Great East Japan Earthquake and the subsequent accident at the Fukushima Daiichi nuclear power plant (NPP) that occurred on March 11, 2011. The earthquake and tsunami caused significant loss of lives and widespread disaster in Japan. Several reports have been published on the nuclear accident; however, the original data released at the beginning of the accident were written in Japanese, and some of these documents are no longer accessible. Some of the scenarios pertaining to the accident have become standardized theories, and these scenarios may be passed down to future generations with different descriptions, which may not fully describe the actual occurrences. To prevent future nuclear accidents, the accident at Fukushima Daiichi must be properly understood and analyzed.
