Improving Bacteria Controller Efficiency

We present a novel approach that would enable the placement of dynamic sensor platforms in the most optimal areas for data collection in an environment of any size. Our approach would ensure that more sensors are placed in areas that contain interesting data and less in areas with little or no data. In this paper, we use a bacteria controller to navigate the environment in the search of interesting data and show that the addition of a flocking algorithm improves the chances of finding data

Bio-inspired vision-based leader-follower formation flying in the presence of delays

Flocking starlings at dusk are known for the mesmerizing and intricate shapes they generate, as well as how fluid these shapes change. They seem to do this effortlessly. Real-life vision-based flocking has not been achieved in micro-UAVs (micro Unmanned Aerial Vehicles) to date. Towards this goal, we make three contributions in this paper: (i) we used a computational approach to develop a bio-inspired architecture for vision-based Leader-Follower formation flying on two micro-UAVs. We believe that the minimal computational cost of the resulting algorithm makes it suitable for object detection and tracking during high-speed flocking; (ii) we show that provided delays in the control loop of a micro-UAV are below a critical value, Kalman filter-based estimation algorithms are not required to achieve Leader-Follower formation flying; (iii) unlike previous approaches, we do not use external observers, such as GPS signals or synchronized communication with flock members. These three contributions could be useful in achieving vision-based flocking in GPS-denied environments on computationally-limited agents

Discrete event simulation and virtual reality use in industry: new opportunities and future trends

This paper reviews the area of combined discrete event simulation (DES) and virtual reality (VR) use within industry. While establishing a state of the art for progress in this area, this paper makes the case for VR DES as the vehicle of choice for complex data analysis through interactive simulation models, highlighting both its advantages and current limitations. This paper reviews active research topics such as VR and DES real-time integration, communication protocols, system design considerations, model validation, and applications of VR and DES. While summarizing future research directions for this technology combination, the case is made for smart factory adoption of VR DES as a new platform for scenario testing and decision making. It is put that in order for VR DES to fully meet the visualization requirements of both Industry 4.0 and Industrial Internet visions of digital manufacturing, further research is required in the areas of lower latency image processing, DES delivery as a service, gesture recognition for VR DES interaction, and linkage of DES to real-time data streams and Big Data sets

Human Nature and Social Order: A Comparative Critique of Hobbes and Locke

Central to most intellectual debates on political organization is the issue of human nature, for one’s understanding of it influences one’s prescriptions on how best society can be governed. This paper examines the contractarian theories of Hobbes and Locke in their attempts to identify the conditions for social order. Deploying a critical and comparative method, the paper identifies the failure of the two theories to recognize the complexity of human nature, a complexity which forecloses the plausibility of a descriptive straitjacket. The paper further argues that contrary to Hobbes’ pessimism and Locke’s optimism towards human nature, the individual has qualities which point to a delicate balance of both. Consequently, the paper highlights the imperatives of social order in a manner that accommodates the complexity of human nature. It concludes that it is on the basis of the appreciation of these dimensions of human nature that we can hope to evolve an enduring social order

A vision-based terrain morphology estimation model inspired by the avian hippocampus

AbstractHoming pigeons are known for their ability to return home after being released from a location spanning up to hundreds of miles. They make use of detected visual features in the environment, the earth׳s magnetic field as well as using the hippocampus region of the brain to construct spatial maps of the environment. This is unlike present day UAVs that rely on GPS and radio/satellite communications with a ground station, both of which might not be available during a major disaster scenario such as a solar flare.In this paper, we take inspiration from the avian hippocampus and develop a preliminary model for estimating a terrain׳s morphology using visually detected features on the terrain. This could then be used to localise a portable micro-UAV during a demining task for humanitarian purposes in third world countries affected by buried land mines from previous wars. Our goal is that in future, the presented model and algorithm in this work would enable effective coverage of an affected area using the visual information obtained from the environment

When reason is not enough for social cohesion: rethinking the place of emotion and art in politics

Reason has often been defended as critical for the prudent harmonisation of competing interests, security and social cohesion in organised societies. Human rationality however, now appears inadequate to cope with the spate of conflicts and dysfunction in many societies, postcolonial Africa inclusive. Thus, imaginative approaches to fostering social cohesion are required. In this paper, I argue that the dichotomy that elevates reason (equated with logic) and derides emotion (equated with irrationality) is not only misplaced, but also unhelpful. I defend art as a valuable vehicle for creating the dialogic space that fosters empathy, make politics affective and promote social cohesion. I conclude by advocating a complementary integration of reason and emotion, with particular focus on empathy, as a remedy to dysfunctional, antagonistic politics, especially in societies confronted by the complexities of diversity

Reparation, slavery and political realism: The challenge of contemporary African leadership

In spite of some revisionist attempts to rationalise slavery as just another form of trade between interested parties, there is an overwhelming conviction that it represented an age of man’s highest inhumanity to fellow man. Accordingly, calls have been loud and persistent as to the need for reparation which though will never compensate for actual loss, nevertheless has the possibility of symbolising  penitence and serve as cushion for some of the debilitating damages done. This paper examines the moral basis of the call for reparation. In agreeing with the moral validity of the claims, the paper probes further in a realistic manner and argue  that African states in their present situation cannot make a serious case for reparation. The paper argues further that for African states to position themselves for genuine reparation struggles in this age of political realism, urgent steps must be taken to  ensure the useful and productive deployment of available resources in Africa and remove the continent from its appendage status with the west. The paper concludes that only when African states are able to break the cycle of poverty and  underdevelopment, freeing themselves from external manipulations can a credible and rewarding case for reparation be made.Keywords: Reparation, Slavery, Realism, Africa, Leadershi
