Serpens: A Highly Compliant Low-Cost ROS-Based Snake Robot with Series Elastic Actuators, Stereoscopic Vision and a Screw-Less Assembly Mechanism
(Peer reviewed; Journal article, 2019)Snake robot locomotion in a cluttered environment where the snake robot utilises a sensory-perceptual system to perceive the surrounding operational environment for means of propulsion is defined as perception-driven ... -
Belief Propagation Detection For Large-Scale MIMO Systems With Low-Resolution ADCs
(Peer reviewed; Journal article, 2019)We derive the belief propagation (BP) detector for large-scale multiple-input multiple-out communication systems where the low-resolution analog-to-digital converters (ADCs) are used to save the power and hardware costs. ... -
A robust two-feedback loops position control algorithm for compliant low-cost series elastic actuators
(Peer reviewed; Journal article, 2019)Elastic joints are considered to outperform rigid joints in terms of peak dynamics, collision tolerance, robustness, and energy efficiency. Therefore, intrinsically elastic joints have become progressively prominent over ... -
Relative Quantum Time
(Peer reviewed; Journal article, 2019)The need for a time-shift invariant formulation of quantum theory arises from fundamental symmetry principles as well as heuristic cosmological considerations. Such a description then leaves open the question of how to ... -
Theory of bifurcation amplifiers utilizing the nonlinear dynamical response of an optically damped mechanical oscillator
(Peer reviewed; Journal article, 2019)We consider a standard optomechanical system where a mechanical oscillator is coupled to a cavity mode through the radiation pressure interaction. The oscillator is coherently driven at its resonance frequency, whereas the ... -
Serpens, a Low- Cost Snake Robot with Series Elastic Torque-Controlled Actuators and a Screw-Less Assembly Mechanism
(Chapter, 2019)Even though a few examples of elastic snake robots exist, they are generally expensive and tailored to custom-made hardware/software components that are not openly available. In this work, Serpens, a newly-designed low-cost, ... -
The algebra of observables in noncommutative deformation theory
(Peer reviewed; Journal article, 2019)We consider the algebra of observables and the (formally) versal morphism defined by the noncommutative deformation functor of a family of right modules over an associative k-algebra A. By the Generalized Burnside Theorem, ... -
A comparison between a two feedback control loop and a reinforcement learning algorithm for compliant low-cost series elastic actuators
(Chapter, 2020)Highly-compliant elastic actuators have become progressively prominent over the last years for a variety of robotic applications. With remarkable shock tolerance, elastic actuators are appropriate for robots operating in ... -
Anchored kernel hashing for cancelable template protection for cross-spectral periocular data
(Journal article; Peer reviewed, 2019)Periocular characteristics is gaining prominence in biometric systems and surveillance systems that operate either in NIR spectrum or visible spectrum. While the ocular information can be well utilized, there exists a ... -
Inclusion of human values in the specification of systems: bridging design and systems engineering
(Journal article; Peer reviewed, 2019)This paper investigates a method for ensuring that systems engineers generate requirements related to human values. It looks at the work of a project team that designs and develops complex systems in a company recognized ... -
Solution Validation and Customer Needs Understanding in the Early Phases of Product Platform Development; a Case Study in Digital Manufacturing Machines
(Journal article; Peer reviewed, 2019)We have observed in our company that the high‐level specification of new products is difficult. The company works with legacy product platforms. Even with extensive knowledge about legacy products and applications, it can ... -
Improving the information transfer between engineering and installation; case study at AS Nymo
(Journal article; Peer reviewed, 2019)Engineering, Procurement, Construction and Installation (EPCI) projects for the offshore oil and gas industry become more and more complex, with a reduced timeframe, and increased demand for cost savings in the industry. ... -
Applying and analyzing A3 Architecture Overviews in a complex and dynamic engineering environment
