Media Project

This article discusses Echo, an environmental media project that explores the possibility of defamiliarizing representational structures of nature through creative practice techniques. Through a reflective, critical analysis of Echo, this article examines how the 3D scanning process, used at the threshold of viability, can illuminate the fragile conditions of data and the complexities of photographic representation. I argue that movements from the plane of environmental forces and forms into a digital materiality carries meaning in addition to signifying practices. This article suggests that viewing environmental photomedia through the lens of posthumanism and materialist philosophy offers the possibility of opening up more-than-representational meanings within materialities, processes, practices and art encounters.

The article sets out to unveil the challenge of drugs in Njega and Kamuiru secondary schools of Kenya. With drug challenge becoming the single major threat to the entire education system in tropical Africa, the sampling of the two schools will help in opening up the matter for decisive action by the relevant stakeholders. Methodologically, the article begins by theorizing the issues regarding drug menace as it wonders: Why do teens engage in this vice? What are the practical effects of drug abuse? And more importantly, what can we do to arrest the challenge? Even though the article has not given the final solution on how it can comprehensively be tackled, it has however opened up possibilities that can lead to the final onslaught. The materials in this article are gathered via oral interviews, some selected readings, participant observation especially through visiting the specific sites, and through critical analysis.

Over the past three years, the author has pursued a method for developing interpretive exhibit materials that synthesizes ethnographic approaches, critical analysis, and creative practice. The term “mimetic inquiry” is used to describe this method, drawing on articulations of mimesis as a “thematic concept” that tracks through the history of aesthetics as a process of representation-with-transformation. The author also discusses the genesis and goals of mimetic inquiry.

The paper shortly illustrates the general concept of Reverse Engineering, which includesalso the 3D scanning. In the main part of the paper the concrete 3D scanning process of chosen individual objects are described. The problems that occurred during 3D digitizing of individual parts are step by step discussed and solved. The paper deals with 3D scanning of ball nose end mills and screw drill. The article gives a procedure for digitizing and comparing the results of the scanned digital models of the two ball nose end mills and screw drill.

Currently, 3D scanning technology is used for high-precision measurements and fixing the geometric shape of various objects. However, when creating a computer 3D-model as a result of processing the array of data obtained from the scanning process, may contain errors. Errors may related to the features of the studied object (material, weight, size, location), functional properties of the software used or they may be the low qualification of the software engineer involved in processing 3D scan data. The task of this work was a finding the technical solutions, which allows one to reconstruct the objects surface, recorded using 3D scanning in the process of creating their computer 3D models. We proposed to use the inverse distance method, which is used in biometry to improve the quality of reconstruction of the 3D surface of a human face. Experiments have shown that the result of the reconstruction makes it possible to increase the accuracy of creating 3D models by recovering gaps in the surface of an object that were made during the 3D scanning process. The proposed approach allows one to construct a 3D surface without solving the triangulation problem, which leads to a reduction in computational costs.

Accessing remote objects that might be hard for a human being to reach to has become feasible by the use of mobile robots, which can be equipped with numerous gadgets to facilitate the purpose of using this robot. Scanning a remote object to study it or build a model of it is one of the applications where such mobile robots can be used for. This research aims at providing a cheap and efficient robot that performs 3D scanning of remote objects in order to build a model at the controller’s station. The robot has its own obstacle avoidance and distance calculation mechanism, but it can also be remotely controlled. Images of the object are captured by two cameras; one normal camera and another Time-of-Flight dedicated camera for capturing the depth of the object. The collected fragments of the images collected by the scanning process are sent wirelessly and securely to the controller, where a CAD model is built of the scanned object’s received data. The application will be applied on Festo Robotino because of its movement that supports this job as it uses Swedish Wheel drive.

This paper provides a detailed critical analysis of the case of Coman, where the Court of Justice clarified that the meaning of the term ‘spouse’ in Directive 2004/38 was gender-neutral, opening up the door for same-sex marriage recognition for immigration purposes all around the EU, thus destroying the heteronormative misinterpretations of the clear language of the Directive practised in a handful of Member States. The state of EU law after Coman is still far from perfect, however: we underline a line of important questions which remain open and which the Court will need to turn to in the near future to ensure that marriage equality moves beyond mere proclamations in the whole territory of the Union.

This paper represents the focus on developing efficient algorithms that reduce the operations required to be employed in order to obtain complex surfaces milling finishing toolpaths for the three axis NC (Numerical Control) machine within the reverse engineering chain of processes. Direct machining is the process of generating efficient toolpaths directly from the digitized data, meaning the point cloud. The entire research is focused on determining the mathematical calculus able to interpret the data collected through the contact/noncontact 3D scanning process. In this direction, two algorithms were developed to generate ball-end mill finishing toolpaths for freeform surfaces using ordered/unordered point clouds. Practical work that validates author’s employed algorithms of obtaining finishing milling toolpaths uses the point cloud stored from the 3D scanning process in matrix found in ASCII files, which makes data interpreting easy.

The object of the publication is to present the validation process stage (operational qualification) of developed assumptions for customised clothing manufactured in industrial conditions. 12 special clothes were made and adjusted to the individual dimensions of firefighters’ silhouettes obtained in the 3D scanning process as well as 12 special clothes adjusted to selected size subgroups after the 3D scanning process from the same identified group of 12 firefighters. Two batches of clothes having undergone the installation qualification were submitted for testing in real conditions (operational qualification). Then, on the basis of data collected from the ongoing functional tests, a batch of six sets of individualised special clothing for the Fire Service was produced in industrial conditions (changing the manufacturer and model of the clothing). A positive result of validation (operational qualification) of this batch of clothing in functional tests conducted in real conditions will allow its introduction to industry through training in production plants and procedures of individualisation of advanced protective clothing design for people working in environments with a high degree of risk to health and life. The individualisation of protective clothing design, through a better fit of the size of the clothing to the body of the user, will significantly affect the comfort of use, ergonomics of the clothing, and the safety of the user.
