The Past

This paper considers the work of two scientists, Darko Bajlo who first detected advanced waves in a set of experiments on 3rd December 2016 to 5th January 2017 and Talaaki Musha experiments on 1st February until 1st March in 1996, who got weight reduction of a capacitor by feeding into it an electromagnetic field. From both their work I see the possibility of an experiment of combining both experiments to send advanced waves into a capacitor to see if the mass shift of the capacitor is shifted into the past.

Bicycle Rider

Over the past several years, the number of materials routinely employed for the fabrication of major bicycle components (e.g., frame, fork, and handlebar) has increased from one (steel) to at least five (steel, aluminum, titanium, fiber-reinforced polymers, and magnesium). Historically the primary driving force for implementation of new materials in bicycle manufacture has been the almost fanatical desire to reduce the weight of the bicycle. Although weight reduction of the bicycle will continue to be important, an old design paradigm—driven mostly by the recent popularity of bicycles designed to be ridden off-road (mountain bikes)—has re-emerged: the design of bicycles that minimize the amount of road/trail shock transmitted to the rider.

Design Proposal

The importance of computer aided engineering in product development processes and research has been increasing throughout the past years. As e.g. energy efficiency and therefore mechanical lightweight structures of new products plays a large role, optimization tools gained more and more importance. Weight reduction can be achieved by a change of the component’s design and by selection of adapted materials. Such an improved utilization of material can be implemented only if there is an accurate knowledge of the loads and the conditions on the material. As modern composite materials can make a clear weight reduction possible, appropriate tools and methods are necessary within the design process. Even for isotropic materials, the design of complex parts is not trivial. For the design of composites, additional parameters have to be considered, such as number and thickness of the plies and the orientation of fibers. Hence, design by intuition leads only in few cases to optimal parts. For the determination of the basic layout of a new design topology optimization can be used. It involves the determination of features such as the number, location and shape of holes and the connectivity of the domain. Today topology optimization is very well theoretically studied and also a very common tool in the industrial design process but is limited to isotropic materials. Several approaches for the determination of optimal fiber orientation have been presented in the past e.g. placing the fibers in the direction of the first main stress. Based on a finite element analysis, a method is presented that uses the orientation of main stresses to determine optimal orientations and thickness relations of plies. It is now applicable to complex 3D geometries. The result is a design proposal for the laminate structure (orientation and thicknesses of plies), taking multi-axial load cases into account. To determine a design proposal for complex 3D laminate structures, the application of both methods, topology and fiber optimization, is appropriate. Regarding an independent serial application of topology and fiber optimization it makes sense carrying out topology optimization in a first step and the determination of fiber orientations in a second step. An integrated approach might show even better results in certain cases. For that, we combined topology and fiber optimization in a two-level approach by optimizing laminate structure within each iteration of topology optimization process. In this paper topology and fiber orientation optimization are integrated into a straightforward, automatic way.

The Magnetic Field

Over the past years, an increase in the amount of the electromagnetic sources could be observed. Model presented in this article is limited to the impact of low frequency fields generated by the e.g. electrical power lines or magnetic coils in a bone fractures therapy. Particularly, the effect of the magnetic component of the electromagnetic field on stents will be evaluated. The conductivity of human tissues will be investigated. Yielded results will be used to simplify complicated, three-dimensional problem of the current distribution in stent branches, to one-dimensional one. The merits of the paper is proposing, implementing and using for analysis a numerical model of the stent in magnetic field. The impact of frequency and positioning of stent in the magnetic field will be investigated and current distributions found.

Experimental And Theoretical Studies

Over the past decade, there has been a surge of interest in the ability of hybrid light-matter states to control the properties of matter and chemical reactivity. Such hybrid states can be generated by simply placing a material in the spatially confined electromagnetic field of an optical resonator, such as that provided by two parallel mirrors. This occurs even in the dark because it is electromagnetic fluctuations of the cavity (the vacuum field) that strongly couple with the material. Experimental and theoretical studies have shown that the mere presence of these hybrid states can enhance properties such as transport, magnetism, and superconductivity and modify (bio)chemical reactivity. This emerging field is highly multidisciplinary, and much of its potential has yet to be explored.

AbstractAn analysis, based upon exact relations and previously published approximate relations, is presented. It describes the connection between changes in aircraft weight and changes in the energy to revenue work ratio (ETRW), which, for a given aircraft on a given route, correspond to changes in trip fuel burn. This is used to establish the link between weight saving and fuel burn improvement at both the total aircraft and the component levels. The analysis is then extended to address the impact of trading weight savings anywhere on the aircraft for increased wing aspect ratio, whilst the aircraft total weight remains the same. It is shown that, for flights in excess of about 350 km, if saving fuel is the objective and provided that all the aerodynamic design and airworthiness requirements can be met, it is better to trade weight saving for increased aspect ratio. In general, the ratio of fuel burn reductions for traded to non-traded weight varies with aircraft size, design range, distance flown and payload carried, with the maximum values, for typical operational payloads, ranging from 2•8, for the smaller aircraft, to 2•2 for the largest aircraft, with medium haul operations deriving the largest benefit. It is estimated that, over the past 50 years, about 10% of the operational empty weight has been traded for increased aspect ratio, giving close to a 20% improvement inETRW. Finally, estimates are produced for the impact of weight reduction and traded weight reduction on the fuel burn for the current global feet.

Software Engineering for Mapping Radio Frequency PollutionElectromagnetic fields radiation has raised concerns within several segments of the population in the past three decades. Many studies proved inconclusive, in part due to the scarcity of data. We propose the idea of a geographical model based radiation pollution database. We discuss networked sensing technology for detection and monitoring of electromagnetic fields. We elaborate on software engineering issues for the visualization in real time of electromagnetic field mappings and the dissemination of information through various means and levels of access. We propose the database be complimented by a data algorithmic software solution for the extraction of patterns.

Experimental Values

We apply a QCD motivated quark model, which was tested in the past for the calculation of isodoublet mass shift of several hadrons, to calculate isospin mass splitting of charm baryons. We find that the mass of [Formula: see text] is heavier than the mass of [Formula: see text] (an interesting as well as surprising result) when we compare the quark contents of these particles. Our theoretical value [Formula: see text] is also in agreement with recent experimental values [Formula: see text] by ARGUS.

A continuum survey of the galactic-centre region has been carried out at Parkes at 20 cm wavelength over the areal11= 355° to 5°,b11= -3° to +3° (Kerr and Sinclair 1966, 1967). This is a larger region than has been covered in such surveys in the past. The observations were done as declination scans.
