1. Multiple allocation p-hub location problem for content placement in VoD services: a differential evolution based approachSoumen Atta, Goutam Sen, 2020, izvirni znanstveni članek Opis: In video-on-demand (VoD) services, large volumes of digital data are kept at hubs which are spatially distributed over large geographic areas and users are connected to these hubs based on their demands. In this article, we consider a large database of video files, that are pre-partitioned to multiple segments based on the demand patterns of users. These segments are restricted to be located only in hubs. Here, users are allowed to be allocated to multiple hubs and all hubs are assumed to be connected with each other. We jointly decide the location of hubs, the placement of segments to these hubs and then the assignment of users to these hubs as per their demand patterns and finally, we find the optimal paths to route the demands of users for different segments having the objective of minimizing the total routing cost. In this article, a differential evolution (DE) based method is proposed to solve the problem. The proposed DE-based method utilizes an efficient function to evaluate the objective value of a candidate solution to the proposed problem. It also incorporates two problem-specific solution refinement techniques for faster convergence. Instances of the problem are generated from the real world movie database and the proposed method is applied to these instances and the performance is evaluated against the benchmark results obtained from CPLEX.

2. My Sister Who TravelsMartina Caruso, katalog razstave Opis: This exhibition offers the viewer new perspectives on this genre, through the landscapes in the work of six women artists. Landscape art is often considered in Romantic terms. Human analogies between the concrete world and the inner world are frequently drawn, and the open space of the land can be seen as a space for imagining, for thinking freely. But these public spaces are also contested sites, layered with histories and the implicit legacies of control, power, occupation and exclusion.
Ključne besede: landscape photography, history of photography, 19th century, 20th century, 21st century, women, gender, Mediterranean, video art, Halida Boughriet, Corinne Silva, Paola Yacoub, Noor Abed, Jananne Al-Ani, Ursula Schulz-Dornburg, Esther Boise Van Deman, migration, capitalism, patriarchy

3. Conversing with Ghosts of the Previously TamedMartina Caruso, 2019, izvirni znanstveni članek Opis: In this article I argue that representing animal-human relationality in contemporary video art shows how certain artists are addressing recent philosophical perspectives such as object-oriented ontology within a posthuman and post-anthropocentric paradigm. While the philosophies that treat the posthuman, from object-oriented ontology to speculative realism and vital materialism, imply a utopian refusal of hierarchy between human and non-human existence, artists may be hard-pressed to represent the described new order, which, at the moment, does not exist socially or politically.
Ključne besede: post-Anthropocene, animal-human relationality, non-human, posthuman, object-oriented ontology, speculative realism, vital materialism, video art, Basma Alsharif, Christoph Keller, Corinne Silva

4. Barve v filmuAlen Dolšak, 2021, diplomsko delo Opis: V pričujočem diplomskem delu sem predstavil potek celotnega postopka barvne obdelave filma, orodja, ki jih uporabljamo pri tem postopku, ter osnovno znanje, ki ga potrebujemo za barvno obdelavo filma.
Poleg tega sem se dotaknil teorije barve ter razumevanja, kako barve delujejo kot pripovedovalno sredstvo na podzavestno (čustveno) raven.
Opis procesov je razdeljen na dva dela, in sicer na opis procesa, ki izvaja večina študentov, ter opis procesa, ki sem ga sam uporabljal zaradi posebnih ciljev, ki sem si jih zadal za svoj praktični del diplomske naloge.
V zadnjem delu diplomske naloge sem opisal cilje svojega praktičnega dela, filma z naslovom Preden odideš, kako sem jih dosegel ter težave, na katere sem naletel med montažo filma.
Ključne besede: barvna korekcija, barvni prostor, LUT, logaritmični zapis, HDR, video montaža

6. Efficient and secured video encryption scheme for lightweight devicesRajan Gupta, Neeharika Chaudhary, Anika Garg, Saibal K. Pal, 2014, izvirni znanstveni članek Opis: Technological advancements in the field of multimedia have made access to information effortless. As information is available easily to everyone so it is quite essential to shield secretive data. This paper focuses on encrypting videos using confusion and diffusion at various levels. Chaotic skew tent map and nested piecewise linear chaotic map which are categorized under piecewise linear maps have been used for the processing. Two skew tent maps are cross coupled with each other to generate random values. The binary sequences are generated by comparing the outputs of the cross coupled piecewise linear chaotic maps. The generated binary sequence is used for bit level diffusion. Further, pixels are shuffled to provide higher level of encryption. The ciphered video is of the same size as that of plain video. The proposed scheme is of low complexity and provides high level encryption. The security analysis of the technique has been carried out and better results have been found regarding the statistical and differential attacks. The code development has been done in MATLAB and the scheme is applicable in areas like Video Encryption, Steganography and Digital Watermarking on various lightweight devices.
Ključne besede: video processing, multimedia encryption, chaotic maps, lightweight device security

10. Ma' NeptunPeter Purg, umetniško delo Opis: After the Neptun Trilogy (2011-13) and its Re:enactment in 2014 (vimeo.com/119334124) as well as its Resiege in 2017 (https://vimeo.com/235908183), the performer returns to The ex-Neptun factory in Komiža, island of Vis (Croatia) for the sixth time altogether. Throughout 2017, the factory was used as one of the strictly closed areas on the island for shooting of the Hollywood blockbuster Mamma Mia 2. Many Komižan mothers worked in the Neptun fish-canning factory for years and decades; dozens of young women came to work in the factory from mainland, they mostly stayed, and became mothers...
