Songs of the Dead is a photographic exploration of the aftermath of a devastating fire that impacted the community of Fort McMurray in Alberta Canada on the 3rd of May 2016. Six months after the fire, stimulated by media coverage and reflecting on the discourse surrounding dispossession and the environment, the project commenced at ground level with support of a Royal Photographic Society Environmental Awareness Bursary in a region inhabited by Anishinaabe1 located within Treaty 8 Territory, the traditional lands of the Cree, Dene and unceded territory of the Métis.
The visual essay presented here is centred in the wake of a major fire event, however, it is also about human law and ecosystems. By traversing discussions on ethics within documentary photography and briefly exploring the history Aftermath of this medium, we argue how photography can better address socio-ecological issues within climate change through poetics. We offer a way of resisting the norms of documentary photography, resulting from subject and process-driven methods.
Collision course: Bagnara crumbling without care?

Bagnara - Castelvolturno - Photo by Mario Ferrara
 
«Collision is the crash, the impact between two bodies in motion» (Treccani, “Collisione”). In the landscape, movement characterises both the evolution of built parts and the mutability of natural parts, and new balances or new imbalances are defined starting from the possibility of recognising stable or unstable lasting arrangements. The intermediate areas between city and nature are the place of contact between the different modes and speeds of transformation of the natural and artificial components of the landscape. The contact between these components can be defined as an encounter or a collision, depending on the greater or lesser level of acceptance or rejection that is produced by the intersection.
The collision is therefore identified as an extreme figure for interpreting the relationship between different phenomena that is difficult to translate, with the same power, into a design theme. «In the passage from analysis to design, it seems that the term collision tends to lose its precision to some extent. Its descriptive power rarely goes beyond the level of metaphorical evocation to become an operational design tool» (Corbellini 2015, p.69).
In Bagnara - Castelvolturno, indiscriminate construction has come into collision with the uncontrolled power of the sea. In this coastal landscape of southern Italy between the Volturno river to the south and the Agnene canal to the north, the unstable balance between land and water has created a narrow sandy strip dotted with houses' ruins and inhabited by bathers. The lack of breakwaters leaves the sea currents free to erode the beaches; the presence of houses built illegally on state-owned land put the inner linear city beyond the boundaries of stability. The current landscape of Bagnara consists on the one hand of a sandy shore, with unique characteristics on the Campania coast, which acts as an unstable base for crumbling ruins, and on the other, the water swallows up shreds of buildings that become artificial rocks. The sinuous curves of the sandy and watery nature of Bagnara are juxtaposed with the rigid folds of buildings broken by the slow catastrophe.
A social and aesthetic practice, photography, understood with Olivier Lugon as a documentary art, explores this landscape, becoming tangible evidence of a reality in oblivion that presents a multifaceted and complex pathological dimension. Illuminating, revealing and disseminating the state of health of Bagnara is the only cure currently in place for this landscape. The photos, like a “caress on the world” of this unstable strip of land, provide a therapeutic practice and a poetic vision of the crumbling reality of Bagnara.

To understand the landscape as heritage is to recognize it in a synthesizing condition, as a complex system of ecological, historical and social legacies. This approach allows an articulation and reading of the territory not as a sum of particularities but rather as a particular system, where the landscape, as a collective construction of society, is not only understood as a material construction, but also as a construction of memory and cultural expressions, which in the Atacama Desert have become evident with a clear mining emphasis, temporally since pre-Columbian times and spatially throughout the transversality, longitudinality and altitudinal levels of the territory.

Grounding is a basic measure to guarantee the security, reliability of the operation of the system and ensure the safety of humans and living things when there is a ground disturbance in the electric power system. In research on the earthing system, what must be considered is the nature of the soil as the place where the grounding system will be installed. The difference in soil type and acidity will affect the safety quality of the grounding system. This study discusses the acidity of the soil to get an appropriate earthing system on different soil textures. The research method used is direct measurement of acidity and resistivity of different soil textures. As well as analyzing by calculating the optimization of 4 types of earthing system namely Rod, Multiple Rod, Plate, Mesh and Grid-Rod technically. The results of the analysis found that each soil has a different level of acidity. The stronger the soil acidity, the smaller the type of resistance produced. A good acidity level is used for the grounding system (pH <7). Unequal acidity causes different types of soil resistivity, so the shape of the grounding system will vary according to the texture and type of soil.

Hotspots are signaled areas that refer to certain places (usually public places) and have internet services using wireless local area network (WLAN) technology. Because the installation of the device and the user who is accessing it is indoors, of course it will be faced with a barrier / barrier in the form of a wall that prevents the entry of the radio signal so that the hotspot signal coverage is unable to cover optimally. This condition occurs in the WLAN network of Agrokomplek Building, Udayana University. So it is necessary to measure the coverage area of the hotspot signal so that no blank spots occur. The results of the measurement of the 4th floor coverage of the Udayana University Agrokomplek Building showed that the signal coverage experienced a lot of attenuation caused by distance and barriers in the form of walls. To increase the signal level value, an access point is added in an area that does not get signal coverage.

Parking space is a facility that must be available in public places, both in shopping areas, offices, hospitals and other places. In general, parking lots only provide parking slots to occupy cars without a system that provides information to the driver about the availability of parking slots, often the driver must surround the parking area to determine whether there are still parking slots that can be occupied. Design and build this application using the Computer Vision method, with the help of CCTV cameras. In making this application, the reference object for detection is a four-wheeled vehicle and the detection uses the Structural Similarity Index Measurement (SSIM) method by taking photos of full parking slots and empty parking slots with four-wheeled vehicles. Then two sample photos will be compared with the threshold method. After getting information about the availability of parking slots, the data will be sent to the server which will then be forwarded by the android application in real time. The results of designing this application have several things that are very influential on the level of detection, namely the intensity of light and camera position. Resistance to light changes of at least 50% of the template that has been made, while the distance of the camera to the parking slot is very influential. The farther the camera the smaller the precision produced by the system.
