1.1. Logical Necessity of the Three Dimensions as a Unit of Thought The mathematician does not look kindly on the simple question of why natural space should consist of precisely three dimensions. Instead of giving an answer he assumes a silent smile and shows us a version of space with an infinity of dimensions, as if space were some kind of toy for him to fiddle with to his heart's content.

The purpose of this paper is to invite managers and practitioners to reflect on the meaning and implications of the concept of zero for individual and organizational spiritual growth.

Building on spirituality and complexity literatures, this paper stimulates non‐traditional thinking in organizational change and leadership. The paper uses the concept of zero as a creative metaphor for organizational development.

The paper introduces a systemic, unified, multidimensional, holistic, complex, chaotic and dynamic paradigm for organizations based on spirituality: paradigm zero. Zero represents paradox, transcendence, interconnectedness, balance, modesty, creativity, inspiration, and the essence and mystery of human existence.

This paper invites managers to consider a futurist perspective called zero‐centered thinking that enables creativity and reflection in the middle of complexity.

This paper builds on cutting edge spirituality and complexity concepts to enable new thinking for twenty‐first century managers and professionals. Zero philosophy provides organizations a new trans‐disciplinary paradigm based on spirituality, complexity, chaos, systems sciences, quantum physics, emergence, and Sufism.

The traditional view of quality treats it as an economic good which can be developed by incurring costs. Proponents of total quality management have rejected the traditional view and stress the complementary nature of cost and quality. Reconciles these two views as different manifestations of the same underlying phenomenon within the same strategic framework. This requires precise definitions of quality concepts such as conformance and performance quality. The organization first examines its current position within this framework. The definitions of quality help sharpen the formulation of strategic objectives and the framework helps in mapping out a policy for moving the firm from the current position to the desired position. In addition, also determines the operating systems of quality management by how quality is defined in the organization. In conjunction with the strategic direction, the operational management procedures facilitate the process of cost management.

As part of the R.A.E.‘s critical study of the aero‐isoclinic principle of wing design, a detailed examination was made of high‐speed aeroelastic effects on manoeuvre point, with special reference to the effect of rearward movement of local aerodynamic centres at super‐critical Mach numbers. From the results of calculations, using the method of R.A.E. Report No. Aero. 2320, it is concluded that as regards possible shifts of manoeuvre point, the aero‐isoclinic wing is generally superior to the conventional wing. For tailless aircraft, application of the aero‐isoclinic principle makes it possible to employ wings of an aspect ratio much larger than is considered practicable with conventional design. Structural design of a flutter‐free aero‐isoclinic wing entails radical departures from orthodox procedure, and with tailed aircraft it is therefore probably preferable to adapt the design of the tail plane and its attachment, to cope with the destabilizing deformability effects of a conventional wing, than to eradicate such effects at the source by aero‐isoclinic design of the wing.

The paper published below was prepared by Taylor Ostrander for Frank Knight’s course, Economic Theory, Economics 301, during the Fall 1933 quarter.

The purpose of this paper is to propose a new algorithm for independent navigation of unmanned aerial vehicle path planning with fast and stable performance, which is based on pigeon-inspired optimization (PIO) and quantum entanglement (QE) theory.

A biomimetic swarm intelligent optimization of PIO is inspired by the natural behavior of homing pigeons. In this paper, the model of QEPIO is devised according to the merging optimization of basic PIO algorithm and dynamics of QE in a two-qubit XXZ Heisenberg System.

Comparative experimental results with genetic algorithm, particle swarm optimization and traditional PIO algorithm are given to show the convergence velocity and robustness of our proposed QEPIO algorithm.

The QEPIO algorithm hold broad adoption prospects because of no reliance on INS, both on military affairs and market place.

This research is adopted to solve path planning problems with a new aspect of quantum effect applied in parameters designing for the model with the respective of unmanned aerial vehicle path planning.

This article presents a simple and objective formula to determine a tender's price-quality ratio, for the purpose of value-for-money awards, which is literally quality divided by price (Q/P). Most formulas used in public procurement today first translate prices into points, in a process which has several flaws, and in the end they do not produce any actual ratios, a fact which makes them less objective. To adjust the proposed Q/P formula to the relative weight of the price criterion from the buyer's point of view, all tenders start out with a fixed quality score to compress or expand quality differences between them. Tenders then compete for the remaining range of quality points up to the maximum, and in the end have their quality score divided by the price that they offer.

This paper aims to develop an adaptive unscented Kalman filter (AUKF) formulation for orientation estimation of aircraft and UAV utilizing low‐cost attitude and heading reference systems (AHRS).

A recursive least‐square algorithm with exponential age weighting in time is utilized for estimation of the unknown inputs. The proposed AUKF tunes its measurement covariance to yield optimal performance. Owing to nonlinear nature of the dynamic model as well as the measurement equations, an unscented Kalman filter (UKF) is chosen against the extended Kalman filter, due to its better performance characteristics. The unscented transformation of the UKF is shown to equivalently capture the effect of nonlinearities up to second order without the need for explicit calculations of the Jacobians.

In most conventional AHRS filters, severe problems can occur once the system suddenly experiences additional acceleration, resulting in erroneous orientation angles. On the contrary in the high dynamic accelerative mode of the new proposed filter the errors would not suddenly increase, since the additional to cruise accelerations are being continuously estimated resulting in substantially more accurate orientation estimation. This feature causes the associated filter errors to gradually increase, in the event of continuous vehicle acceleration, up to a point of zero additional acceleration that subsequently causes a subsidence of the error back to zero.

The proposed filtering methodology can be implemented for orientation estimation of aircraft and UAV that are equipped with low‐cost AHRSs.

Traditional AHRS algorithms utilize the accelerometers output for the computation of roll and pitch angles and magnetometer output for the heading angle. Moreover, these angles are also calculated from the gyroscopes output as well, but with errors that increase with time. Of course for some applications of AHRS system, orientation errors can be damped out with a proportional‐integral controller. In such a case, the filter cut‐off frequency is usually selected experimentally. But, for high accelerating vehicles utilizing AHRS, the system errors can become very large. A possible remedy to this problem could be to use more advanced nonlinear filter algorithms such as the one proposed.

This paper aims to identify the reasons for the lower ranking of the Online Service Index of Sri Lanka under the United Nations E-Government Readiness Index. The study is conducted as a comparative study on selected Asian countries and suggests remedial measures for the improvement of the status of e-government of Sri Lanka.

In this regard, as the sample of websites ranked according to the Online Service Index of the United Nations, five government websites of Sri Lanka, India, Bangladesh and Singapore were selected. They are the national portal and the websites of the five Ministries: The Ministry of Education, Finance, Health, Labor and of Social Services. Asian countries selected are India, Bangladesh and Singapore including Sri Lanka. Observation method was the mainly used method for data collection. The websites were evaluated in contrast with the help of the “Main features reviewed by the United Nations E-government Survey” as the checklist. Substantial description and scoring methods were used for the analysis of the data and the presentation of the findings of the study.

Thus, several weaknesses of the online services of the government websites of Sri Lanka were identified. Among them, the major reasons identified for the lower rank of the Sri Lankan Online Service Index were, for example, the inability to identify the exact website of national portal, the lack of accessibility or usability features, the weaknesses in the active maintenance of the “Contact us” feature, service-delivery capability features, citizen participation and also interconnectedness features. The above weaknesses have been the key/root causes for the decline of the rank of the Online Service Index of Sri Lanka.

From five government websites, selected three foreign Asian countries were in focus because of practical limitations. Another difficulty faced in the analysis and comparison of the websites was that the information with regard to the United Nations evaluation methodology/criteria has not been adequately provided.

The findings of this study provide information for the policy makers, web standards, evaluation criteria developers and almost all the government organizations to address key issues related to this field for the maximization of citizen participation, the enhancement of the service-delivery capabilities and accessibility features of websites to improve the online services of the government. This study unfolded several areas for the future researchers. Those researches can also be conducted based on sub indexes of the United Nations E-Government Readiness Index. The same method could be used to examine Human Capital Index, Telecommunication and Infrastructure Index and Citizen Participation Index. This research could also be expanded through observations of foreign countries.

This paper provides an overview of the quality of government websites of Sri Lanka compared to the selected Asian countries. Through the utilization of this scoring method, four major weaknesses that contribute to the lower ranking of the online service of Sri Lanka were identified with suggestions indented for the improvement of the government websites.

A three-dimensional (3D) printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy. The purpose of this study is to analyze the influence of such errors on printing accuracy and printing quality for delta-robot 3D printer.

First, the kinematic model of a delta-robot 3D printer with an ideal geometric structure is proposed by using vector analysis. Then, the normal kinematic model of a nonideal delta-robot 3D robot with tilted vertical beams is derived based on the above ideal kinematic model. Finally, a 3D printing error simulation approach is proposed to analyze the influence of tilted vertical beams on the 3D printing accuracy.

The results show that tilted vertical beams can indeed cause 3D printing errors and further influence the 3D printing quality of the final products and that the 3D printing errors of tilted vertical beams are related to the rotation angles of the tilted vertical beams. The larger the rotation angles of the tilted vertical beams are, the greater the geometric deformations of the printed structures.

Three vertical beams and six horizontal beams constitute the supporting parts of the frame of a delta-robot 3D printer. In this paper, the orientations of tilted vertical beams are shown to have a significant influence on 3D printing accuracy. However, the effect of tilted vertical beams on 3D printing accuracy is difficult to capture by instruments. To reveal the 3D printing error mechanisms under the condition of tilted vertical beams, the error generation mechanism and the quantitative influence of tilted vertical beams on 3D printing accuracy are studied by simulating the parallel motion mechanism of a delta-robot 3D printer with tilted vertical beams.
